So as some on who loves to problem solve I thought I would share my first world problem and solution. So during the lockdown, we purchased a hands-free foaming soap dispenser this thing has had a mind of its own as light-sensitive so have moved it around the downstairs bathroom and now randomly dispenses soap on the floor so have decided to make a catcher so it will go in the sink.
So out with callipers and radius tool, this is a game-changer
now I have some radius and dimensions I have made a simple sketch infusion 360 that i will now take from 2d to 3d.
I then printed a small test form so I could make sure it fitted the operation as didn’t want to make a 17hr print to find it did not fit.
test print just to make sure all is wellfront is a tight fitrear wont fit
ok so have adjusted from the wall to the front lip as 96mm fitted front but there is a 2mm deviation further you go to the corner. So now ready to print the 94 mm version just need to order some PETG in white that will be here tomorrow before I kick off the 17hr print might even film it for fun.
Time to print fingers crossed this will fit.
so will check back in the morning to see how it’s done as it’s only 54 mins in time to play some VR on my oculus quest 2 before I check in on it again. woke to spaghetti filament had jammed thankfully it stopped itself. So away we go again.
3hrs in will check back later
16hrs om there’s been some warpages on the base but should not matter 1hr 50mins left I’m going to bed report back in the morning.
Well, the results speak for themselves and works well I might add some foam tape to fix it in place as it does move when pushed.
here’s is a list of tools I have printed and have found useful to help make create and fix issues in my workshop. these are all things I have tested and used in my workshop some have been featured by others but hay this is my definitive guide to what i am using in my workshop at the moment.
this is a must for workshops that have lots of small parts that they need to put in small draws. this is my go-to tool when I get boxes of screws in to sort into their draw project.
nice quick 1hr 32 to print nice and compact to store.
3. Airbrush Wall Mount Holder with Drip Trays & Anti-Tilt by cncartist file can be found here.
in my very small workshop means my airbrush is easy to access off this handy little wall mount.
4. Screwdriver bit wall mount by SaKes file can be found here
use this and its remixes for drill bits and all my quick release bits.
As you can see I have a whole collection of bits easy to access with these wall mounts.
5. Spray can wall mount by Isalvador file can be found here
great for clearing some more spaces off my shelves for more kit and tools got 8 cans mounted behind the cave monster might add more. as a nice quick print, any wall space is a game changer for extra space have since got carried away and done both sides of the racking.
6.Disposable Glove Holderby mkelly file can be found here
12h48 print but saved me around £15 buying one off amazon.
Been meaning to buy a glove holder to mount on the workshop wall, As I have a box of nirol gloves kicking round workshop covid/resin work/ resin printing etc and I found this box so 1 money was saved for the next creation.
Metric Screw Hex Nut byJigby HDRI file can be found here
was a little slap hand with the pen highlighting number works well.
Love this great for determining what size that bolt you need is within seconds just used this as had a screw was too long by 10 mm so placed it in the guide figured out it was a 40mm bolt and I needed 30mm also identified it was an m5 bolt I required. one for my small tools tray. great for sorting that box of mixed bolts I have kicking around.
Wall-mounted spanner holder8 pcs by DaFed file can be found here
more saving spaces in draws as every spare wall space is used in my workshop as it’s so small. found this the other week love it went for the 8pces version as just needed to clear some space from my toolbox and this worked for me.
there are more bits I’m currently printing and testing which I will add to this list in the near future
you will need a licence for fusion 360 I have a free hobby licence that is limited but till i get time to learn the cam side of the program it’s free to me unless Autodesk feels kind and wants to give me a licence. not that they will read this anyhow.
open up fusion 360
the file I am going to remix is this spray can holder.
Now to remix it or in this case, I am going to create 2 bars for aligning it on the wall by using its original parts as a template. over to fusion
then go to insert drop-down insert mesh
you then can position it how you want i this case will keep it as it is so select ok,
now press s on your keyboard then type mesh you will select convert mesh.
Now select the stl
then hit ok on defaults as all other options only in paid verison.
sketch will now look like this
at this point you can simplify the sketch and make it fewer polygons by selecting segments and removing them hitting delete as shown below
selected poligondeleated smooths up shapepartly cleaned
So why do this well on flat surfaces makes it easier to select planes.
go to the sheet metal tab select Create Sketch, you are now going to select face to edit.
select highlighted plane and click you will now see it like below.
I am going to start off making a bar so i am going to hit L on the keyboard and will give me a line command.
as I am using snap to have determined the endpoint where I want to start the line click mouse to start the line
I next go to the bottom right corner of where I want the box i am making to be this will give me a guideline.
like below can now draw the 2 lines needed
close the shape
Now hit enter.
so that is literally the only bit i need for my idea but actually going to 2 as I want the top and bottom lugs to make int to alignment bars. so going to repeat this process and then we will continue.
I am now going to remove the original part from the system as i have the 2 elements i require for the alignment bars as will be easier than removing all the material I don’t need.
then hit del and sketch will remain
now to extrude it on both parts 100mm as think it’s a good size so hit E on the keyboard when selected object
hit enter and repeat on the bottom section of the file now change view please not i have moved them together for illistations.
Now to make the parts you now want to go to utilities tab select make
select the parts and in chose options as 2 body will need to do this twice.
this next part is as I have set my Prusa slicer to open when I make them so at this point you could save them as stl
now the part is in my slicer i am going to set it up for print by changing position before i save it out as an stl.
first to make it flat to the bed i will use the place on face tool F for a quick keyboard cheat
will select the bottom face
part ready to print in this case going to save it as a stl.
click the part then right-click and select Export as STL
save and parts done. then added them to one file ready to print will show more detailed remixes soon
then its over to the printer via octoprint in my case and away it goes as i have doubled up the parts as to racks going on the wall will take 2hrs to print.
parts all done ready for a test fit.
perfect fit love now to glue them all in place.
can find my files here do love a quick 1 day project parts are in to finish off the cr-10 so that should be up soon.
this has been a bigger build than I first expected around 100 hrs of printing a lot of remixing was involved so some things worked some things I have had to print again and again till correct. think they are all correct now as they fit for me.
As will any project files they are a work in progress. still need to reprint final fixes to test but the current design work with some drilling or being an angel so no rush for me. i would say there are a good few days of printing involved with this project. but well worth it.
So what this part covers:
All in one Cr-10 Remixed for Dual Y-Axis linear rails kit
UPS 12v big tree tech
Filament runout sensor big tree tech
Modifing TFT screen firmware.
Dragon Hotend and issue correction
BISQU Flexplate
All in one Cr-10 Remixed for Dual Y-Axis linear rails kit
This is a remix of this design by Cornely_Cool can find the original design here. you will need these files for some of the builds my remix replaces the front-rear panels front left panel and several of the base plate files. this is a work in progress it works for me as of me writing this blog post.
So why am I doing this the original printed mod I built-in part 3 or 4 doesn’t work with the upgraded linear rails so It doesn’t fit so going to make something using an existing design with a remixed twist as its not 100 % right for me due to the dual linear rails and the design wasn’t using SSR and some other bits. First up going to salvage parts and order up some metal work going to raise the machine 60mm and have another 70 hrs of printing ahead of me first up parts. needed some aluminium 2020 and 2040 some connectors to hold it all together some corner plates and some new rubber feet as I disposed of my original feet from my cr10 also have hight clearance is an issue with a shed roof. might still need to lower racking. have also ordered a small 5v 3amp PSU to internally power the pi that’s running the printer. as this is a custom build have also ordered some aviation plugs to tidy up the wiring and install better-suited wiring. I will have a sonsoff switch as master power on and off and use relays to turn on and off power and lights for web camera. I will publish a full shopping list. end of the post when I have calculated what I used and what you will need. will add build of material
Time to start the remix so starting with the base panels going to remix the Mosfet panel as don’t use one as running a silicon heat bed. so will house SSR relay, a 2 channel 5v relay for lights and printer and UPS board if and when it all shows up.
this is done using the panel as a reference and using PCB footprint diagrams have added a 6mm standoff for each part.
will house SSR UPS and 2 channel 5v relay it a work in progress relay fits just only screws fit
Next up I am going to remix the raspberry pi and pi PSU plate as I am going to use a hard-wired PSU 5v 3A so will need to make some mount holes for the PSU but first going to test its powerful enough. as I don’t have a reference diagram going to photograph the underside of the PSU and measure it using it as a reference image. will then trace holes for mount. won’t print it till I have tested PSU. have made some air vents and bars so i can make holes to mount it when it’s done.
the PSU holes are off as on the wrong side but will drill and bolt PSU in place. The final file changed but might be off.
The final modification is to the mainboard fixing plate so used the existing plate as a reference for size then added footprint overlay to trace holes for mounts.
insterted image of board set to size as reffrenceadded standoffs on over layexstruded finlal plate for prinnting
the final hurdle was going to print the massive PSU plate on the cave monster cr-10 but due to wiring snagging I cannot print on it so into Prusa slicer have cut it in 2 will print half and half on both the Prusa so I can do it in half the time will line up and glue the halves together.
love the cut functionas i have the print farm up and running i will print half one both the printers so saving time.
Now that I have remixed all required base plates now I am going to centre the middle post I have remixed the font panels to be blank as due to the dual linear kit I cannot fit a front-mounted screen. so going to remake the panels to smaller and more central with a 5mm notch to allow for fixing plates.
Gone for a central notch 5mm deep changed it again since this maid it longer.
Next, up is the power plug panel got to notch this and move the power connector as it’s right in the way of the plate.
slotted for brackets with 5 mm and move power connector by 20mm to the right changed it again as just on the borderline.slotted by 5mm ready to print.The last plate finishes just base plated to finalise. just had to add a hole for cables for the screen
The last panel was modified for screen cables for mounting to the frame.
Time to start printing I am going to run it all in PETG. time for some overnight parts I am going to set my Prusa’s going shame I haven’t reinstalled Octofarm to run this but will do on the next build as will be running 3 printers in it. About 4 days in now all printed apart from pi and PSU mount that’s currently running and some fixing brackets. time to build the base has been tweaked the construction of the metalwork with some extra brackets to make sure this going to the stable with the printer on top of it.
last part on the prusa printing then to assemble it all.
Oh wait fan director last 8hr print that’s overnight parts for as I am already deep in assembly.
last print of base builds overnight parts.
Time to build it.
Time to put it all together for the final time hopefully and I can then put a pin on this machine.
first up assembled outer frame with base runners and corner plates with the feet i have brought. will bolt down the centre rail once I have centred it on the base plates.
metal works arreved atime to start putting togethercenter rail in time to bolt it togetherand im out of 10mm blots damit.
now I have a squared base I will add the uprights and bolt them down with the L brackets i have sanded the tabs on the printed walls so starting from 2040 I placed the first part I then added a bit of 2020 in the middle and continued on till all the walls was installed then using 2040 plates i bolted the base to the 2020 uprights. I will add another bracket on top of this to secure the printer to the base.
First panel is in. all the walls are fitted.
now on to the base panels, I will place them loose before I add the fixing clips in place.
fr dry fitting panels.all fits well.not 100% lining but will workjust going to change pi panel as psu wont let me fit the power connecot to pi.
all my components line up perfectly well almost but still bolts down sold just need to adjust the centres slightly as the footprint diagram I found is wrong on the relay. I am getting better with each project build. now everything is in place have added the clips have bolted down all the components apart from PSU as need to modify it for the upgraded fan.
fitted new PSU base plate but holes are off, needs to modify
Final version the pi & PSU plate is done holes are wrong but I just drilled new ones and screwed it down with some 6mm M3 bolts I will start wiring up tonight.
actually going to need cable management. so time to fire up the Prusa 1 more time for a plate of connectors.
the last print for the base.
The wiring
First up will run the mains wiring from the 3 pin kettle connector to the Sonoff switch then across the on/off switch for the pi PSU and the main printer PSU. now I have the main power in.
Main power all in forgotten my wifi password so I cannot test the Sonoff all fit perfectly.
Next, I will run negative connections for the 2 channel relay and link the relay to the pi so I can control it via Octoprint. I will then run the positive to the PSU and lights circuit for the web camera. next up are the jumpers from relay to the raspberry pi going to use 5v ground gpio 23 and 24 pins I am also going to use 3.3v and pin 9 ground and pin 14 for a temperature sensor inside the enclosure so I can adjust the fan if it gets too hot inside.
Ok, my worries about the mini PSU and voltage is fine there is no under-voltage which is great as sometimes things are not what they are advertised as.
time to pull out the wiring diagram for the mainboard.
list all connectors as you can see negative and positives are needed on end-stops and thermostats if not get kill alarm so on the end-stops and thermostats square is= to ground.
end stops and motor connecotrs are wired board side got to do some soldering but will cover that later as need to make some new wires for the heat bed and y-axis.
I am actually going to modify one of the front panels to house a Micro sd card reader and a fan speed controller PCB so back into fusion 360 going to add foot block and add 2 3mm holes to mount the front 2 PCB holes as then in the main plate I will add an 8mm hole for the potentiometer. then over the other side of the panel, I am going to cut a hole for the sd card reader to squeeze into I will then fix it with hot glue. as the original design used a USB switch to allow for firmware update the skr board only allows for MicroSD upgrade so as the board is going to be embedded this will allow for firmware upgrades in the future.. this will be a 4 hr print I think. as I test fitted the 2 halves I needed to reprint this anyway as it’s off by 10mm so now will fit perfectly under the front plate support
So out with the callipers, I go to make everything will fit and is sized correctly. time to modify the sketch.
will do an overnight prototype print. well, morning has come and yes everything fits fine just need to screw the PCB down and hot glue the sd card extension in place and we are a bit of sanding for the tabs and should be good to fit. note to self make sure you sand the tabs another 3 hrs print and will defently resand the front panel as snapped a tab these things happen when prototyping but its starting to take shape.
whilst I’m at it going to add 10mm space on the rear power panel as it was very tight prefer there is some wiggle space more airflow as well going print it on ultraviolet tonight back on with the assembly tomorrow.
redesigned as was too tight on the centre spacers.
All panels are now fitted going to cut myself an aviation plug holder jig. so out with a sheet of acrylic time to cut and bolt together.
So over to light burn a sheet of acrylic in the machine let make this design I got off Thingiverse https://www.thingiverse.com/thing:4201220. I have relayed it out slightly different as I want to fit on a sheet of 300×400. if someone wants it will share it.
as I want a good connection going to start with the 4 pins i have given up on the six-pin as NEMA wiring is too fragile.
ready to cut.
Not everything you find on Thingiverse is right so had to modify the file slightly to get it to work but now a more compact jig. as the dfx is segmented and didn’t cut right in light burn fixed now and modified the base as was too big for smaller workspace ready to solder tonight. got 1 socket to solder
assembled ready to make my new connectors
Nice and neet now for the heat bed connector need a new connection as the board is about 20cm further than it was originally also my bad soldering means it intermittently doesn’t work. so time for a fresh connector.
time to solder up a new heat bed connector with longer wires so I can wire direct to PSU and solid-state. out with my soldering iron I know the following
Pin 1 = Thermostat Positive if wired wrong alarm will sound on SKR board
Pin 2 = Thermostat Negative if wired wrong alarm will sound on SKR board.
Pin 3 = Heated Bed as 220vac voltage don’t matter which goes to witch
Pin 4 = Heated Bed as 220vac voltage don’t matter which goes to witch
2 down 2 to goready to instll
have put continuity meter across the pin and end of the cable and they all check fine
now to wire it all up and we should be good to test.
all ready just need to shorten the neo pixel cable as made it way too long. going to use the bit I chopped the neo pixel wire I will use for the filament run-out sensor cable. Then it’s time to finesse the cable management.
The next issue the fan direction vent is hitting the y axis so going to make my own custom offering so going to find the footprint of 120mm fans going to make it easier to fit low profile fan shrowd. should have space as gone for 35mm high to 19mm high
So should have good clearance space. 6hr print will run tonight need to swap filament as running low on Neon orange.
Done just need to see if it fitssd and fan controler fittedrear shot of it all.just isnt sitting right.new Fan air directonal. nice and compact but does buffer the air might modifiy it more in the future,
The wiring list is getting shorter just time consuming getting there.
end stop and motors temperature sensors and relay wiring left before I’m done.
Time to link the raspberry pi to the relay using 5v ground and pins gpio pins 23 and 24.
Temperature sensor installs time so using 3.3v ground and Gpio pin 14 for the probe have added the Dupont connectors to go over the gpio pins going to have to do some changes via rasp-config to let the system know pin 14 is sensor pin. but will check if this is needed or not as it is an old guide I read. I will also need to add a plugin so it will display the internal temperature of the enclosure so I can monitor and adjust the fan speed accordingly.
going to have to change the sensor type as this type I have installed does not have a pull-up resistor on it so just ordered another type off eBay so will swap it out.
Temprarture sensor installedJumped to the raspberry
Finally, The wiring is now all complete just need to test everything works.
finished all internal wires oh wait missed the lighting circuit Relay.
The camera light relay I have pre-made a cable from the 12v supply the positive will go to the power connector negative will go via the relay so I can switch camera lights on and off when a print starts and ends. have had a change in the design as I’m not using USB switch going to wire power connector to where the switch was going an install an A to A USB panel mount so I can connect the camera to pi externally power will be via the relay so I can turn halo on and off if required, should have parts Monday. as I wired the power socket tonight I had a thought about the USB connection wouldn’t work. back over to fusion 360
power for light rig is in.
Designed the first version it’s printing now but it’s not going to work as needs relief for the screws so have remixed it further and come up with this going to print it so have both options but think this is the winner.
v2 think this is the winner
As you can see from original to remix v1 and final v2 these are the things you have to take into account when remixing a project.
orignial version 1 and 2
In fact, I am going to redesign it again as the cable layout is different so back into fusion I go doing a scrapy print to see if it works but this should be the final design have made a few changes including screw head relife and it fits perfectly added to the remix pack
version 3 with cut out for plug that turned up
this project is pushing my design skill and I love it.
the finished item I do love playing around in 3D print.
Time to fit it all into the machine.
fitted like a gloveall wired in
Right, I am on the home straight I need to make some form of protection for the printer’s innards.
going to cut some black acrylic insert them in the middle of 2020 extrusion as dust covers.
so been thinking about how to do this without having to remove the front of the printer going to do some testing. I am going to cut some test bits 20 x 74 mm at a start to see if I can insert it then centre and add a fixing clip to hold it in place I will then make will also design a middle clip that can be removed to gain access. well,
that’s the idea, time to make some test bits. so over to light burn and as I have some offcut left from the jig build going to cut some strips to see what can be inserted,
time to cut some interest to test have labelled them for ease of use
So looking front on Left = 77 middle = 146 right = 75 now to make 2 x 200 long size X plates for each area will then 3D print the customizable design for centre plates then to design some clips that will be after I have the covers fitted.
I have decided to make it a 3d printable version obviously they will be subject to where your cross braces are. but you can customise them in the slicer. i am going to print my covers so they match the base as I could cheat but I want this to be a mostly printable design. also, put a clip together
the first plate is printing
here is the centre plate design will be making left 70mm, 138mm and right 68mm. the centre area 72mm across. total area 100mmFirst panel inone side done.
Clip design I have put these in to hold the panels in 3 per panel so 24 in total. currently printing a sheet.
final plates are printing on the printers should have all the dust covers done tonight then I am ready to assemble the 2 parts have hit one minor snag as the end stop bar is skimming the middle plate need to take a few mm off it to get it to work right will think about how I do this might just be a shorter screw and a 10mm off the tube with a hacksaw. No, I own a 3d printer. so now printing a shorter 11mm x 20mm tube and have a shorter screw to fix the issue.
only issue is the centre plate as the end stop bar is clipping it.
All fixed worked like a charm now does not rub on plates and makes contact with the endstop. all plates fitted made a cut out for dust cover so waring was more neat.
Dry fit works well.
dust covers all fitted and wiring from neo pixel hidden also hidden the filament sensor wiring if there’s any interest will publish all the other bits I found on Thingiverse that used to help with the project.
Yay parts from china
Just as I was about to put a pin in this build and post the post I have now received parts from aliexpress so back on to some more upgrades. lol so this will be tomorrow as one PCB to fit and wire and one sensor to attach. and a Flexi plate to stick and fit.
So a new day has dawn going to try wrapping this up today bar printing or tuning.
UPS big tree tech
This should be easy to install one 3 pin plug to the mainboard from the ups and 12v supply just got to figure out where to place the board in the enclosure I think I am going to make some holes and add some standoffs as I did with the 2 channel relay. need to look into firmware changes for its use will cover this at the end of this post.
My fingers are crossed my calculation for the footprint of the board is correct and this just pops in with some m3 screws. Well, I’m too good fits perfectly just got to finish wiring it up.
Make sure that the + & – are wired correctly as will destroy the PCB if wrong they are labelled on the bottom of the PCB then links them to the power input on the mainboard like shown below.
then insert the 3 pin connector and connect to pwr-det on the mainboard and then back to ups PCB and it’s all installed hardware-wise.
Now for firmware changes
There are 2 files you will need to change first is in the feature folder look for powerloss.h
I have changed debut and saved each cmd this will save the last state on the printer if there is a loss of power now over to the Configuration_adv.h search for POWER_LOSS
then uncomment the above this is set up for my printer mainboard so pin number might need changing on your device. and purge and retract might need changing as well.
will compile this after making other changes for the filament runout sensor
Filament runout sensor big tree tech
As I waiting for this to arrive seller sending another one middle of February so instead of moping around the workshop getting ready for it all to arrive.
Ok have found a bracket on Thingiverse I am going to remix it so I can mount the bracket directly to my 2020 so will be adding 2 tabs in Fusion 360 so I make this a reality. first, I am going to import the mesh in and will draw two rectangles using the top face of the bracket I then extruded them by 4.40mm then made a centerline in a sketch and added matching holes time to print
Quick and dirty modification but will work.
I will print it shortly the spikes will print not sure why they ended up there are joys of modifying a mesh
Just waiting on the current print to finish should relay run the farm but need to get neon orange up and running it’s on my list of things to do. it’s a long list as always.
Printed ready to fit when I get the parts. just test fitted will just what I wanted.
works on 2020 fine.
As I now have the parts time to fit it all to the frame for real as the sensor has arrived.
hidden all the wiring in the frame with some clips.
Going to connect it to the mainboard E0-STOP port you will have to switch it on in the firmware pin 15 was already selected for filament runout.
Now you will need to turn it on in firmware so in configutation.h
find the following FILAMENT_RUNOUT_SENSOR and uncomment it like below.
Next, scroll down and uncomment the following FILAMENT_MOTION_SENSOR and FILAMENT_RUNOUT_DISTNCE_MM set it to 7
and with that just need to reflash with v5 of the mancave monster firmware on the mainboard and we should be good to go.
My Current Firmware CR-10 BTT E3 mini 2.0 with BTT UPS, BTT Filament runout sensor, BL touch and Neo Pixel 18 pixels installed compiled here if you want the vs code files ask and will happily link it for you.
all components are now installed going to join the 2 printer halves and running initial tests. fingers crossed before I permanently bolt them together. Wiring issue, not a big one negative on neo pixel is the wrong way around not a biggie just taken a photo of the pins.
Mine was the wrong way around so out with crimp tools and time to make it right.
remade the connection so let’s test it again. now seems to all be working.
Homes check bl touch works check hot end heats not working for heat bed erm ok not heating need to check the wiring.
Got a feeling negative is what I meant to pass through the SSR going to go back through my notes.
Was 2 issues had heat bed plugged into the extruder and hot end in the bed and the negative was positive no damage all fires up now and works
Just print the front left panel with a modified hole for screen cables. so going to leave that running overnight, just fitted and perfect so that’s finalised.
One thing i will need to revisit is the relay board but I think that will be done in the future as projects are already way overrun and used lots of PETG I really need to invest in centre callipers they are uber expensive one day shall order some.
Time to modifiy my racking
The next job is lowering the racking so I can fit the new printer on the shelf need to move the spool holders down and then drop the shelf level down by 15 cm approx.
cleared the shelf and now to focus on removing shelf and old wiring as will rehouse the wall-mounted pi down also binning cheep fans as they temperature should never get that great and the nose one of them I producing is bad.
spool too lowspool not high enoughJust rigjht
Have managed to drop shelf approx 120 mm have refitted shelf and refitted Prusa’s have moved my pi off the wall and disconnected fan. I shall monitor CPU temp via the plugin.
space is ready for the new printer
Now to place the printer in its place well nearly first flash the firmware and cave monster ready for action well nearly as I want to finish off the mods before I set it in place.

I didn’t use this as couldn’t get to compile I will revisit this
Z_STEPPER_AUTO_ALIGN (in Configuration_adv.h)
so that’s the merlin firmware now done not to look at the config.ini.
custom logo
cave monster
so lots of settings and functions here have changed a handful of colours and the way it talks to octoprint.
next up going to look at the actual firmware pre-compiled so I can see what changes can be made. that will be a separate blog post I have added a new icon set and flashed the screen with new firmware to see if it helps.
Dragon Hotend and issue correction
K decided I would go the full whole hog and upgrade the hot end as well. as I wanna look at the movement in the x carriage on the extruder bracket. I also why it is quite tight on the belt.
Issue 1
I fixed it was the hole the direct-drive bracket is bigger than the m5 to linear rail bolt hole so have used 2 countersunk screws to centre the bracket. works well,
Issue 1 FixedNew hot end fittedexstruder reassembeled
Fitted the dragon
I have removed the old OEM hot end. 2 screws and that’s gone now to fit the dragon hot end using Capricorn petg tube between it and the direct drive all fitted now to put the hot end back together upgrade is done. but not quite right cannot get filament into hot end tubes not quite long enough so time to order a length of it so I can get this right.
Issue 2
I noticed there is a lot of friction on the belt so I am going to swap the pully end around as I want this to be smooth and can align the pully across the beam. 4 front screws removed. pully off and rotated now to put the machine back together much smoother think I have fixed it might need a slight tweak but let home the machine and see what happens.
just going to make a benchy test. before I fit the new flexplate.
running into issues with filament sensor the hot end now clogged got a feeling the Capricorn tubes melted so I am going to strip down the hot end tonight and have a look and see if it’s down to that as removed nozzle and still cannot get the filament to come through. have ordered a back up hot end the big tree tech v6 hot end and a fixing bracket as a backup as got a feeling this isn’t right.
will disable the runout sensor for the calibration as I have a feeling it’s thinking it’s a clog on the hot end even though there is now a clog.
removed hot and cleaned and the issue blockage in the tube put it back together loaded it ran 20mm through it and bam blocked again so might be my filaments shit or the tolerances of the tube is too tight might try a different batch and see if I get any joy other wire going to revert back to my back up but that’s going to delay first print. by 3 weeks but going to launch this part of the build and then come back when it’s all printing right. at least makes me know that the runout sensor working. so will re-enable it after I have a calibrated machine.
going to first install the flex plate whilst i figure this out.
BISQU Flexplate
This is something I love on my Prusa printers will hopefully be the same experience. so to install going to need to stick the magnetic sticker to the glass bed.
so have turned over the glass sheet and cleaned it using isopropyl now to apply the sticker sheet went down will not be 100% straight but no one will notice.
Time to cleanSticker fittedAll installedAnother anglejust need a working hotend and good to test
before I test the plate on top. going start by resetting the EEPROM and then going through calibration again as don’t want to mess the sheet up. but that will be in part 7
all fitted now a waiting game for the new hot end so will leave this here final part will be testing it all out.
So this is all going to be 3d printed mods I have already done a 35hr print on the control board side I have printed the new feet need to print the SSR module clip might set that up whilst I am remote in wales the joys of being connected. so all I will need to do is 2 lids then will be ready for the pro upgrade.
also mounting on the screen on the side of the machine. might need to reprint the printing bracket. as want it on the left-hand side of the machine.
23hrs of printing done should be finished by the end of the day,
so just uploaded it to the local computer and now have kicked off the amazingly long 23min print haha so will only be 2 x 7hr prints left when I get home on Monday. just as I feared the small print it failed never mind noticed and cancelled the print. will check back with the main print later.
80hrs combined printing still a little cleaning to be done
wow, that’s the long prints done now for some smaller prints and armed with elnet the king of hair spray when it comes to getting prints to stick well. as Pritt stick is too messy. wow just saw the bend in the heat bed how did that happen bent it flat again. just going to adust the bed by probe till it’s nearly on the money then I might lock tight them in position for the moment. probably should have done that before I kicked off an 8hr print.
5 layers of 95 done
I will be going over to a flexible steel bed soon but till then I am going to continue on the old fashion way well till the credit card bill rolls and I then have my monthly spending pot.
so smooth a 4hrs to go.
think its dialed in now.
starting to get ready for build
lids and SSR printed and that just under 1kg of filament was done. on the case.
All parts printed for pro conversion
last time it will look like this
so time to strip out the old box and fit the electronics in the new one oh and to add the new feet so it will fit.
just need to order some silent fans as the control box fan is really annoyingly loud so I have orderd 120mm nocturia fan and I think i will need to order 80mm one for the PSU supply. I will be opening that up in the rebuild as one i dont know its voltage and 2 pin numbers 2 or 3 so will order that when i konw.. I then have to think about speed control as i don’t think they need 100% speed but that I will be looking into as we go, as going to monitor temprature with a probe in the electronics low voltage box.
Have been thinking about a name for my cr-10 modified machine that came up with cave monster. so the next round of modifications to the code will include a name change haha. will attempt to design him a logo as well for the boot screen.
as i have been spending alot of time getting everything printed for the next step i have been customising my octoprint layout and feel. also on christmas crafting for friends and family so yes been a fun week that and i am re jigging the work shop as need to add storage for extra tools as need to make it all work.
High voltage side.
time to look at power supply and lable up wring before i strip it out the box. next up power input and switch. I will be making new wiring for all power elements. First up adding the mains power plug and switch. looks like the are going to need a little help fitting so out with the dremal and they now fit. as it cold have stopped halfway through the job as working how and where to route the wiring and fit the ssr to the psu.
Heat Bed mains and switch in
now to figure out this mess
all high voltage done.
Also, going to wire the printer PSU through a 5v relay so i can turn the printer on and off through the raspberry pi cover this in the Low voltage side of the board but will cover that later.
Low voltatge side.
Now i have the power run across the board I will either add the bucks converter to step the 12v down to 5v to run the raspberry pi or I will use a mains adapter this will allow me to shut down the printer where as the other way would be a total power off. whilst I think I will install the pi and the main control board. am then going to install 2-way relay board so i can switch on/off the machine and lights via the relay.
boards in ready for wires
final image for refrence.
need to think about this as big arse fan wil be above this.
Might run the wiring under the main board to keep it away or i mgiht just exstend the wiring.
Time to connect all the power wires and the heater wiring to the board and the SSR.
Now to add all the board inputs and output so end stops motors and sensor
next, it is time to fit the 120mm fan to keep things cool as its a 4 pin I will only use the 12v supply as should work will test this theory later also waiting on t-nuts so I can bolt this to the frame should have them later on today so will finish wiring ready to bolt it all together.
got one more print to go on as adding halo light to the camera so I can film all the loverly creations that I am making with the printer but that will be done once I have installed the rest of the electronics. going to make the camera mount a little more sensible as i feared there’s a little bit of a wobble when running.
testing halo /focus mount is not 100% right but fits and works soldered some longer wiring i will be
As I am waiting on parts as amazon let me down I will be getting the last bits sorted ready to bolt the boxes to the bottom of the printer. ok been a week had a family issue that’s now come to a sad conclusion. so back in London will try wrapping this stage up by Xmas but see what happens.
How my plans have changed
its been 2 weeks of hell over Xmas father in law passed away suddenly so was in wales for a week then came back to london and wife and son both have covid so stuck in london in the house i am negtive and they are both ok.
bad new but good news been working on the project and ironing out my kinks with it so where to start
It dont fit under my printer bed like its ment to due to my custom bed so instead of having a hissy fit throw 70 hrs printing. I am going to let be and will figure it out as i go i have welded the 2 sides together with some high strength glue and exsellitator now bonded together
custom mounts piot holes drilled.
now to screw it in place.
stand offs in and board scured.
relays all wired up.
New power for lights and speed conroller wired up.
All in working
i then have added some custom stand offs for the fan speed controler and 2 channel relay. i then drilled holes for external raspberry pi power and for fan controler knob. oh and power connector for the halo.
bit of wiring changes to the printer can be powerd off and on by the raspberry pi also using the 12v psu to power the halo light as well also had to change the wiring.
and we are good to go i am waiting on the next mods to show up from the far east got one PCB board still to fit so before i bolt it back together and start testing the new fetures
ready for install just power headers for the pi and add USB PCB when it gets here.
I will leave this here. get ready to part 5 this will be the final part i hope. so whats coming well a UPS 12v board from big tree tech. New fexable bed for the machine and fliminet runout sensor from big tree tech and upgraded linier rail upgrade and thats it.
Well as I await parts I will be working on a few issues and also designing some parts.
What I did not mention in the last part is I managed to drop the control box moving the printer back into the cave as it’s so big and the doorway is so tight. it is back in the cave no so I need to do a strip down and see what’s making my Y-axis go in reverse.
I have a feeling it’s damaged cable or end stop both are on order so should start on this shortly as really thought I had come to the end of the update journey. But no it’s become a paperweight well hopefully not for much longer.
So in part 3 plan is as follow.
Fix reversed Y-Axis after drop
Time to invstigate whilst i wait for new bracket
Fit proper X-axis linear rail bracket.
Reinstall hotend with direct drive & Install new hotend part cooler mod
Print a camera mount:
Fixing the reversed Y-axis:
this was working right till the control box that was balancing on the bed fell off and dangled. now the printer when homing goes in reverse. very odd I have ordered a new wiring loom and end switch. going to start by swapping the bent up end stop. that main pull was on and replace y loom fingers crossed. The end stop has arrived going to fit it now and see if that fixes the issues. If not back to waiting for the loom.
Looms arrived was the Y-Axis end stop wiring has broken out with the old in with the new.
Installing the updated motor mount and bed upgrade:
After ruling that wouldn’t fit the mods and I didn’t think they would fit.
I changed my mind and thought what’s the worst that could happen? So have fitted both the bed wasn’t too bad once I had lined up the centrical nuts up. I then added the new motor mount this wasn’t as much fun, as mounting it needed some parts that were not included. fist up need M5 T-Nuts luckily I had some, countersunk m5 screws again luckily I had these. right now to reattach the Y-Belt to the motor and the bed. for F#&k sake the belt is 100mm too short. looked through my draw of printer parts and spotted gt2 belts was a loop cut i and then rethreaded the bed. ok no to reattaching the end stop it wouldn’t fit as the holes in the bracket are for the raw small micro switch so have mounted the original end stop back in place if this causes issues can modify the end stop to fit on the brackets with old bent up microswitch scavenged for bits let us see hopefully not but have a backup plan.
all back together and homes ok so now for the next part of the project.
Time to invstigate whilst i wait for new bracket:
Now that I have a working printer going to do some more testing to see why it’s not printing right.
ski jump did hit camera mount im testing for later. bars hav foiled my install idea.
right has put a spirit level and my z was out slightly so have adjusted one of the rods. and the new result is better but still off. Hoping on the bracket to sort this out a bit better.
Just waiting on the arrival of the X-Axis bracket now as I am sure there that that is also compounding this. So as you might have figured I am doing other bits whilst I wait and updating this post as I go. Hoping by the end this will be an awesome printer.
The bracket is in the UK just waiting on delivery so probably in 48hrs time. so time to strip off The offending bracket and strip down the hot end ready for the new bracket to arrive
Fit proper X-axis linear rail bracket.
Out with the v2 bracket as there’s a 5mm difference between the centres. as you can see I have removed the modified direct drive hot end as I think this is also the issue with print being fine on one side and in the bed on the other. time to add the bracket and fit the 2 screws. before moving on to the hot end and direct drive. it fits but!! mgn9 rails kit not 12 argh never mind ordered new rail so will sort this out next week.
braket fits yes
so happy
old modifed one
Reinstall hotend with direct drive & Install new hotend part cooler mod.
I have repopulated the direct-drive motor I have rotated the motor for cleaner wire management. I will now reattach the hot end and fit the modified parts and hot end cooler as it uses existing fans and screws. I had to get my craft knife on it to make it fit but fits fine
right time to reasemble.
all re attached
bl touch re fitted now to measure off set
I have reattached the BL Touch need to measure the offset form probe to the sensor in the x-axis its -41 and in the y axis, it – 5 so will need to recompile merlin to get it working to make a note of the setting for later. I am already going to need to do this when I add other functions to the board that i will cover in the next post,
Ok next issue
just did a test moving the extruder head to make sure it homes ok and there is a bolt head hitting the z-axis bracket so I have solved this by swapping it for a button head bolt that now makes contact with the end stop so homes fine.
Right, let’s run a bed visualizer scan and see how it is now.
about a mm diffrence across the bed
So out with the solid mounts and I think i will be adding back the springs if i can find them if not will order a set and go back to configuring it manualy.
So back to my box labled printer parts to see what i can find as i have a feeling i saved my springs. YES I did saveI them so will fit them going to to look for some nylock adjustment wheels on thingivers so i can lock them in possition
me being me put the springs back in and spent a hour getting bed as flat as i could before i set saving the mesh and dong the z offset.
Much better
Time to print a camera mount:
I am using a c270 Logitec camera as I do on all my printers as nice and cheap. doh printed the wrong parts need to find another fixing bracket as printed vertical mount instead of horizontal one never mind. Just a few more hours and then will cannibalise a second-hand c270 that I have ordered so inserted about £24 on amazon and got it for £13.
I have used this one before and it worked well so I pre-printed this design that can be found here. All you will need is some m4 nuts bolts and 4 t-nuts is fixed to the framework like so.
not good view
too short
might work
ok, it’s probably going to vibrate like a bitch but I’m game for a laugh lol.
view from the camera lol
Right now up to date with all mods, there are more to come but going to make sure I have a functioning printer before I go splash out on any more parts.
Calibrate and do some calibration prints without issue,
Now that all is working let’s start to play with calibrating the machine and getting it all working right. so first up is a bed levelling program not sure if I need to run this at the start of the print each time. can make it fewer touchpoints and then to calibrate z offset height.
Still needs a bit of a tweak I think will do a few more adjustments to the springs to get it just a slight bit more level as seems beds off a slight bit. I now remember the pain of manual bed levelling but hope it will be worth it.
made some firmware tweaks let see if this fixes the machine. getting there nearly dialled in just got to drop the head a few 0.01s and we should be good for a benchy test.
All sliced up ready to print think that will be tomorrow
Success i have a printed bentchy will be looking at it properly when i get home later.
checked in 20 mins after start
then this monring so it works
so got home had had 1 layer shift so have tightened up the belt and run the print again. now yay had a filament jam and a tangle that made the print fail halfway through so I have decided to 1 make a better spool holder for the printer and 2 go back to sold standoffs or silicon ones so some play but can be locked in a level position.
so whilst I wait for parts again printing spool holder.
Now to glue and fix it to the wall.
It all looks like a good time to print something bigger before I try doing 1 day 12hr prints on it.
eureka is all working well now to do some calibration prints to make sure all is well in 3d printing land.
so after 5 calibration cubes and a benchy or 2 or 3, I think I am nearly bang on as level as I will get it with a bl touch across the bed.
Layer shift tangeld spool
a part from that looks good
New Spool holder installed
Away we go
4 cubes later
time for a final go with black
Conclusion to part 3
Now that I have a working machine I am going to turn it into a pro by losing the control box.
don’t worry this will be part 4 as having a working printer that’s improved the prints and has improved the quite ness of the machine, not the control box but that will be part 4.
but back to the big print
well, about 2 hrs in and it’s printed 2 layers a little bit of stringing but let’s see going to risk leaving it alone for 2 hr or more. ok came back 6hrs later and yes it’s still working I am amazed my self oh well 1 day 3 hrs left on the print.
looking good
Morning all well been printing for 23 hrs now and still going a strong slight bit of warping not bad and won’t affect the massive print this is side 1 of 2. Apparently, 23 hrs to go but it’s 61% complete so I think it will be less.
Happy the machine is working right so will show the finished side a put a pin in part 3 get ready for part 4 more modifications coming up going to order Y linear rail upgrade so we can start speed testing.
35hrs 10 mins and she is done this is pcb side low voltage.
right, this is the end of part 3 as 35 hr print is complete and looks great. did thteh enw feet over night and now doing the rigth hand side so another 35hr print.
then wehen i get back from wales i will print the lids, and start adding the electronics.
but thats going to be part 4 over all its working well so let see how we go now 1% in to next large print.
Part 4 will be all the 3d printed parts and part 5 is going to be the linear rail conversion on the y-axis.
so where we left off printer moved home and levelled then failed so in this exciting chapter going to strip out the control box and add a new brain to the system.
so as I am upgrading the brain I might as well do some more mods so a colour touch screen is included in the kit. so will be adding that as well. I have been watching a few videos on compiling merlin. so have downloaded the nightly bug fix and will talk through compiling later on.
so time to jump back in there. as I have one working printer at the moment I am going to start off with printing the new screen holder as going to lose the control box completely. these things take up space.
so over to Thingiverse and found this Slim and Elegant BTT TFT35 E3 V3 dual-mode touch screen Extrusion Mount see the link here.
Over to Prusa slicer sliced and uploaded to ultraviolet. as neon orange is offline.
away we go will check back in 9hrs time
2hrs 45 mins into 9 hr print
9 hrs later one screen adapter is done
All done
All cleaned up
some M3 screws later and it’s ready to wire lol ok I forgot to take the screen protector off never mind let’s get it all working first.
it fits
stand offs fit
all lines up
spot the reset button
all screwed together time for some wires.
one part is ready to install some m4 bolts and t-nuts and will fit onto the frame.
I will print the pro enclosure once I have the printer working online as the cr-10 is the only printer big enough to print it. will print all small parts whilst I get the cr-10 working.
have tried the y motor mount and dont fit right so abandoning this upgrade for the time being. now to do some compiling
Compiling merlin for the first time.
This is sort of new for me as in have flashed my old original cr-10 board before using Arduino ISP programmer and source code. but now it’s all moved over to the Microsoft VScode environment so much easier to do. as the cr-10 has a pre-built config file it’s for the new SKR E3 mini v2.0 BigTreeTech mainboard that’s repacing the stock board.
so you are going to first up need to install VSCode / PlatformIO programming environment. there are plenty of guides on this. once done you will need to head over to https://marlinfw.org/meta/download/ and grab the latest bugfix file you will then find a link in the config folder for the example zip this houses the configuration.h and configration.adv.h files and boot screen files you will need to drag these into the marlin main folder.
open the project in vs code.
in my case I am installing bl touch so needed to change settings to include bltouch and safe z home, also added about probe offset and a handful of other bit. There are vidoes on this so i wont try explaning it all.
I then selected my board type in the core settings. and built it. after the compile was done I found location firmware.bin and copied it to sd card to flash the mainboard. you will need to power on the machine and it should all be ready with the new firmware. will test this along with the new screen shortly same applies for that can be custom-built or you can just use stock firmware.
Now whilst doing my research for this project. I saw the filament run-out sensor porton the new screen so going to use my filament sensor from my old ezout board as it’s compatible.
I am also going to use neopixle function as well so have ordered 1m of led tape. will be experimenting with this soon as I will need to recompile the firmware to use the function actualy will turn it on now and play later time to do some more reserch as wont complie needs some addtional settings will do them first before first switch on as then when i assemble the board i will be able to playwith it will runn cable ready for it so all in place for when the tape arrives
I am also going to name the machine so i know its talke the frimware before i start testing.
now to upgrade the components.
So out with the old in with the new:
so toime to take the old board out
wiring all swapped over wiring to the new board so that it’s ready for its new firmware. whilst I’m doing this have also fitted the final part of the last lot of upgrades to the machine. new motor bracket fitted.
time to swap over part
halfway done
all swapped over
Time to switch it all on
Time for the initial turn on with new screen fitted in enclosure hole as till I have finished off the new mounting box for the machine won’t mount it till then.
turns on lights up and turns off ok a little bit of googling figured out the issue because i have bltouch wiring plugged incorrectly.
now I can see I have messed up the screen with an improper firmware update. long and short of it don’t copy the update to the sd folder to the TFT screen.
Dont copy over the file saying copy to sd.
only copy theme folder content TFT model number and config.ini and just like that is fixed now to flash the firmware I have compiled with fully bltouch customise on. all done did have a message that bed mesh couldn’t be found but after running bed levelling got a saved to eprom message and that’s resolved that.
its alive ready to do offset and test.
wow, it’s so quiet moving around the printer all I can hear is the noisy control box on my list of things to modify.
Ready to print have done my z offset wish me luck.
nozzles hit temp beds not heating up time to check connections. brb. ok after checking all connectors and solder joints i have done over the years was poles on the SSR some how got switched now heating like a champ.
My first print failed as need to watch a video how to do z offset done right as was about 4mm off the plate but on a realy grate side it works it runs were its ment to. so very happy. watched a video all of the menus have changed but i think i have got it just going to start a test print before i move the machine back to the man cave.
bed seamms very off not sure if its down to my bracket modification.going to look for the bracket set only as then will save money on getting this sorted time for a evening of reserch fingers crossed i can solve this i am going to put this down to my mod of the braket
So have found braket correct x axis braket and orderd it and a new braket 10 to 15 days i will hopfuly be finishing this project. as i am waiting for parts i will do some other mods then leve part 2 here and come back with part 3 when the parts arrive.
Time to print some Upgrades whilst i am waiting on parts
As my wirings got heavier going to print a drag chain to sort that out so overnight parts on the Prusa will report back in the monring.
all done ready to fit. had a near miss with 2 clips shakeing loose. but it servived the nite.
lets see if it works.
all printed
It sort of works but is a little weak for my likeing i am going design my own chain holders for the liniear ralil mount and were the old exstruder motor used to be to use with some stock chain. got to free spome space up from my drive as fusion isnt working,
Hot end part cooler
been looking over thingivers for other mods i can install on my machine as you know me with this ever elvolving project. so as i have direct drive installed i am limeted with hot end cooling mods as i know the stock one is less than great so i have found one that i think will fit so time for another 7hr print. going with the AJS hero v2s as it has bl touch mount and uses factory stock screws so should fit.
will check back in 7hrs
morning time and all cleaneed up very well will be stripping offending bracket later in the week from the machine and install new one wilst i wait for x-axis braket that is alreay shipped from china.
test fit with new braket and have removed 5mm off the top corner with a dremal saw bit. Now a nice snug fit with out interfering with the bracket or hotend.
just got a ghost trap to build for the boy before i get on to stripping down the hote end and removing it ready for the new liniear rails bracket that is shipped already so 10 to 15 days time the project will resume.
Will it improve its printing ability? or will it be an expensive mistake?
This project is going to kill or make my CR10 v1. The story so far :
2017 Received the machine from Aliexpress Creality store.
IT worked out the box did some big prints suffered from ringing kept vibrating off level suffered form glitches and so the story begins
brought the duel z modification less ringing started to get the hump with the board shaking the leaving screws lose. so decided to get the EZABL prob kit brought it got it all set up worked great had a major meltdown and destroyed itself with mass blob filament could not unclog it so I brought a complete extruder. took months to arrive. I disassembled the machine and put it in the attic.
meanwhile, I kept on using the Prusa mk2 that I keep on upgrading to the latest spec so forgot about the cr10.
Lockdown happened health workers needed PPE to save lives I joined a group of people making ppe. I started my print farm going 2 Prusa around the clock pumped out face masks ruffly printing 25 masks a day. but wanted to help more
brainwave I got that cr10 in the attic I can fix it as now 100 times more confident with repairing machines. So fixed the cr10 added silicon bed heater with SSR 1 good print out of my machine then for some reason the bed temp was reading very high in the 800c back in the attic went for another year have moved all business servers in the house so needed the space back so brought the cr 10 back down and put it in the workshop,
since then I have sworn at it a lot as keep tripping over and finally decided enough was enough swapped thermistor as thought that was the issue. it was but wasn’t, I finally figured out that it was the gunked connector in the control box that was that actual issue. fixed it after soldering a new connector into the plug on the box.
After a binge on Ali express and some more local parts, I’m going to modify the F#%k out of it and hopefully not go down in flames.
Let’s get this done.
I am going to lose the EZabl probe as has intermittent issues and the upgrade to a BL touch will mean that the EZout is no longer needed.
So thanks to the 3dprintingkid. I have been armed with a brand new ender pro 1.1.4 mainboard which I will be flashing with the BL Touch upgrade kit and latest Creality firmware. It’s already been flashed with a merlin 2.0x but going to go with the Crealitys version for the time being to see how it performs. if not will make my own compiled version.
So I will then have hopefully reliable levelling probe. next, I will be losing the Boden tube extruder for a direct dual drive upgrade off amazon with some belt tensioners being installed and proper z-axis motor mounts aluminium. I am going to upgrade the 8mm rods with some proper anti-backlash nuts.
Then it will give it a test whilst I wait for the next batch of upgrades to arrive from china within 10 days according to aliexpress.
So we are going to get a custom bed chassis, with an Upgraded Y-axis motor bracket.
then I will upgrade X-axis and Z-axis with a linear rails upgrade kit.
Finally, on to the frame, I will fit a stiffening kit and adjustable z rod holders with bearings.
Well, that’s the modification of the parts done. if they all work will be time to do some 3d printed upgrades.
Time to start.
Time to strip the machine down and swap out the old mainboard ready for the flash update. so first of all I have swapped over the cables and connectors from one board to another.
Cables swapped
New board in
now to remove the old board from the machine. now to bolt the new board in the machine.
Off with old EZABL
Time to remove the ideler
Making a collection of parts off the machine.
Time to remove the extruder
Extruder motor gone.
Exstruder removed
I will also loosen the y and x-axis belts and remove idlers ready for new ones. then will remove the extruder and extruder motor and PETG tubing. So I will be ready for the parts to arrive tomorrow.
A new day and a bit of a build ahead well once Amazon has delivered.
Got the first batch of updates,
Going to be a fun night
First up going to replace Y-axis tensioner with nice solid construction easy to fit.
Fitted and tenctioned
Solid construct
next up time to install the new extruder drirect drive kit.
Ajusted and fitted the new direct drive
Had to remove 5mm off the capricon pteg tube.
Exstruder now filts and can be screw down.
Time to fit the cover and Braket
BL touch Bracet installed just need to fit the sensor.
Time to install the wiring.
Right next up to add the X-axis tensioner again solid construction the supplied screws are too long luckily had some M4 x 10mm screws kicking around nice snug fit.
Going to change the motor mounts as they are easier to fit 4 screws each and done much neater.
Old motor mount
New motor mount and anit backlash
I installed a clone bltouch that didn’t work very well have been waiting on parts to continue the project. kept on crashing into the bed so ordered the official one from Creality
a week on and have most of the upgrades so now time to fit them all first up going to do the x-axis with linear rails. you can find the kit here have to take off my newly installed extruder and add the new rails.
Exstruder stripped off
time to add the brakets
now to add the rail.
now to refit the extruder
That was very easy to do next up is the bracket on the extruder. it doesn’t fit what the F%&k I ordered the cr-10 v2 must have a different head on it. time to modify and make it work! if not will have to bite the bullet and order the correct one so out with my needle files and time to lengthen the hole. well 30 mins later now fits. but then the probe mounts don’t fit right. ok solved that put the bracket on first then nudged it over then the cover fits so looks like it will work I am now going to wire the official BL touch kit. won’t fit it yet as need to remove the x gantry to fit the z linear kit.
lets strip everything off to fit the braket
all ready
it dont fing fit argh
finger file to the modify the part
fits perfectly now
and i think its straight.
all back together ready for bltouch
the one thing I will say about fitting all these parts is there are no instructions just wish that aliexpress manufactures would think about this as would make life easier for us end users.
time to strip down the z-axis and liberate it from the machine then to install the left and right z rail all fitted and now to rebuild x-axis with new brackets. the machine is starting to come together just need to fit the extruder.
had to rotate x motor to get it to fit with the bracket supplied. next up I fitted some side struts for rigidity lets see if they help. can find the struts kit here
all done ready for the extruder.
I just need to fit the BL touch and then do some cable management.
nice offical kit.
all fited
cable managment sorted
had to find screws as non provided for the exstruder
all done ready to flash.
ok now to flash the firmware with Creality ISPprog.exe all done time test. lets do a auto home. argh, mods not allowing me to hit the end stop time for some mods some m3 nuts will act as spacers for the motor mount now works, as with any project some times just need to think out of the box.
time to flash the system
Right auto home x and y hitting wait a moment I have no z oh I see flashed it with standard merlin. Reflashed and all works had some binding issues with z that I have fixed by adjusting the threaded rod screws and my trust spirit level.
Now to offset z so we can start to test what the mods have done for this machine and will I be doing further mods let see quite nervous about the first print.
final bits to install z rod ends are now installed.
time to find a sheet of paper and see if my machine calibrates ok fingers crossed.
away we go auto home done over to Prepare menu then » Move Axis » Move Z now to lower the z till it grabs the paper and then make note of the amount and then go over to
In my case it’s -01.50 go up to the main menu then go Control » Motion » Z Offset enters —01.50 time to store the offset.
go back to the Control menu, then select Store Settings. The job is done now to test print
Failure of the bog-standard Creality firmware 1.60 has issues I think the printer is heating auto homing then going through the bed levelling part then it starts to extrude and rocks backwards and forward on the front of the bed. hmmm
F@@K it 8bit Creality board can go do one time to spend some money as I said going to throw upgrades at the printer till it works right.
Have ordered bigtreetech skr mini e3 v2 with TFT screen so will be compiling my own version of marlin for my 32bit board.
I think I will also swap to linear rails kit for Y-axis I might just sell on the custom bed as the kit comes with all the parts including the bed.
so I am going to end this here till I have the new mainboard and can make some progress.
have since moving my Prusa mk3s to its new home on some racking been having issues finding a good wall mount spooler for it. so have been testing some from Thingiverse and www.prusaprinters.org that will fit into my set up. There might be more if none perform right.
16hr print start16hrs later.rods and screws all installed as well as plastic membrane
The buidl:
Now as i have some 8mm tubing and all the bits have arrived from aliexpress time to build the box and see how she performs.
the print time is 36 hrs per box one failure as my new filament sensor was not turned on doh. hence the 2 tone box. still dialling in the printer.
funny looking humidity gauge thanks aliexpress.
Oh, Just opened up my humidity monitors from aliexpress turned out to be temp gauges so have ordered 5 more from bangood hope these ones are right but for time being they are going to be temp ones till bangood deliver.
the build come in 2 x 16 hr prints for each side of the shell. you are going to need 4 bearings and 2 x 100mm aluminium 8mm tubes 1 x M3 x 5mm. 2 x M3 x 10mm. and 2 x M3 x 30mm. and a panel mounts humidity meter bag plastic from a ziplock bag and some silica crystals to dry out the box.
the 8mm tube is a nice tight fit so i got some sandpaper and smoothed each end to allow bearings to fit better. then pushed them into pockets in the base of the dry box I then fitted the lid and added the 2 x M3 x 30mm bolts to the hinges and screwed them in. the M3 x 5mm holds on the lid catch i had to ream the channel that the plastic nub fits into slightly to get a nice tight fit. i also added another m3 x 5 mm to the lid to help it lockdown this was not mentioned in the guide but works well you then use a ziplock bag to cut out a rectangle window for the filament to go through this is then bolted down using 2 x M3 x 10mm bolts. as i have bags of silica gel i have added 2 to the box.
I then positioned the box to were I wanted to mount it I then use 4 self-tapping wood screws to fit it to my wall behind my printer.
Time to test.
very stiff on pulling out filament going to do some more testing later it’s not working right might be the cheap bearings from china. will play some more with this but taking up wall space. so going to remove it and test next design.
Conclusion:
my issues might be the cheap bearings i used. so will revisit this design shortly as like the idea of having my filament stored during our winters.
As this one has been designed for Prusa printers i am hoping this will work for my set up its a clever system going to take 3 print runs to build have finished printing the base around 6hrs to print and am currently running the legs that a further 9+hrs then i will do the spoolers 9+hrs. you are going to need some parts for this build luckily i have all the parts from the days of printing fidget spinners. 8mm threaded rod from previous projects.
Legs are currently on the printer did the base earlier.
Parts list.
160mm M8 Threaded rod.
4 x 608 bearings.
2 x M8 nuts
The Build.
all built up ready to mount.
In my case, i had to cut down a 1m bar threaded with my junior hacksaw. then ran the first nut to end of the bar. insert the 2 legs into the base ad 608 barings to each end of the spoolers. thread the bar through the bearings the legs and add the second nut tighten till not to much play one the spoolers.
attached mine to the wall with 3 self tappers and then covered with the hex caps.
fits the space perfectly
Conclusion.
This is the one for me as holds 2 full-size Prusa filament spools and easy to swap in and out. will be testing this over the next few weeks. as I am installing a heater in the next few days i will not need to have a covered spool.
Right finally go this out after a few months of issues and printer problems i can see the light.
As it was Sunday night and wet i thought i would bring the Prusa in for its upgrade as its time i fixed it once and for all.
One of the perks of being a Prusa owner is when new tech is produced they release an upgrade kit. So armed with a Pepsi Max cherry my electric micro screwdriver a pair of pliers and a screwdriver i set to work.
sunday night fun ready to start the upgrade
got the footstool and a box and made a little workshop in the living room as my little one was in bed.
All stripped down box of bolts removed time to upgrade
so after 30 or minutes or so i had taken apart the old extruder and was left with bare z-axis ready for its new extruder to be installed. now to install the new extruder.
Do love the online manuals nothing missed. what you see on the screen is what you need to do.
about an hour and 30 mins into the build and starting to button up the extruder getting ready. for electronics. section of the upgrade
All done 2 hrs later yes i missed some square nuts and had to rebuild x backplate again doh missed that section of the manual it’s fine as was easy enough to do. right all built.
Downloaded latest software and firmware of the Prusa site ready to flash it. all done flash successfully. Time to calibrate my machine and hope the upgrade has fixed it. here goes nothing. ok seft test passed auto home passed XYZ calibration failed arg going to call it a night as 1 am in the morning on a work night.
Monday evening feeling bit on the tired side. I have managed to speak with tech support online chat and was asked to check the P.I.N.D.A probe yes think i must have been tired as had not plugged it in last night doh. Ok, let’s get back on to the calibration one last check of the P.I.N.D.A probe hight and found it needed some minor adjustments. time to calibrate
4 point calibration to start off with fingers crossed.
Yay, its passed all calibrations and have dialled in the first layer hight. done a simple test print all working. time to move it back to the cave. time to test it’s all working. first long print. 12:30 am fist layer looks perfect time to sleep.
have checked on it this morning and its still printing. So i think i have solved issues with my mk3 will post an image of first printed half of the spool holder later on my return home.
Will put an image of the first half printed later here
That one working Prusa Printer now to fix the Mk2s MMU as then can print multi-coloured prints. without the expense of pallet 2 +. Fingers crossed on that one as then will have a full set of working printers at home. That will probably be on my return from Walse as got a house to get ready for our first renters so a busy week/week end.
Will be printing 5 spool holders so i can have a full set of multi-material printing and the mk3 at the same time.
