This is a daily blog that i will be doing during the lockdown as i want to keep a record and show day to day operation in this strange time. as try to keep my mind off the virus.
Printing lots of PPE and cutting screens for PPE along with making buttons to give away to people rasing money for the NHS our life and blood in the UK. during this strange times.
Then today i finally got around to looking at my Prusa i3 Mk2s MMU yes i know i have promised for months i was going to do it. been sitting in the house for 2 night keep putting it off. to day i decided to take a look so took off the mixer and noticed that the Square nut that the mixer head goes in to was not aligned in the hole so i out it were it should be and thought wouldn’t be that easy well it was managed to print a calibration cube dialed in the first layer just printing some wall brackets as i am going to be running filament from above.
So now have 2 working prusa’s do i look at the CR-10 tomorrow and got for the hat trick.
Have also made moved my resin printer out the way so i can have both printers next to each other. just printing brackets so i can mount my spools of filament above the printer. will check out the MMU at a later date as PPE is what i am running.
lets see how this works just installed this bracket from thingivers can download it here will need some ptfe tube to get the bracket working.
Next up will be moving my heat press’s out of my workshop and install my cr-10 back into the man cave to get a 3rd machine running. Well hopefully as i am on a roll of fixing and braking stuff mmu went down again last night my fault but back in the game again now adjusted idlers wrongly. now ready to print again.
So once i have had a postman come should have more filament till then i will use up my old supplies. No filament found some Neon Pink in my store so some colourful prints coming up.
going to start date and time stamping live blog as i do more work on my machines.
bah mmu down again got one more thing to try if not i will go back to the drawing board. or bite the bullet and get the upgrade to mk3s full kit. did not even manage a full print.
also dident get a chance to do cr-10 last night as put the boy to sleep and felt knackered.
any how enough excuses back on with trying to get the mmu and cr-10 going.
CR-10 is shorting issue as plugs come lose looking for a pin out diagram.
Found it on my one of my prior posts Doh. i have just pulled my gas soldering iron out and re solderer properly. Just got to put the boy to sleep and we are good to flash the freshly compiled firmware then will build a raspberry pi for it and add it to the network.
Flashed sd card with fresh copy of octoprint now to get to on the house wifi before then have to change it for the mancave wifi later but for configuration house it. just going to dig out a USB cable bring the printer back in and then the fun can begin.
Going to flash the firmware with latest version of TH3D firmware.
Right its not going to happen tonight i have a thermistor showing an ambient temperature of 730c its a silicon heat bed so not sure i just change it going to do some reading and call it a night will resume in the morning.
Happy modding printing creating and enjoy these strange times.
Morning all back on the case had some thoughts about some further testing on the cr-10 as it might be a motherboard issue so going to get my multimeter out and probe the thermistor with my trusty multimeter to see what readings i get as when recompiled the firmware last night to not have the silicon bed it dropped to 499c so wondering if its an issue with compensation with software. so will take some readings should see 100.00 ohms ish for room temp are right or wrong. if right will approach the TH3D and ask some more questions. i have also been donated a motherboard from the 3dprinting kid so might do a complete board swap out. see if that fixes the issue.
Have a user of the Prusa owners group come back with some suggestions so might give that a go as well see if we can get the MK2s mmu stable as have all the parts. first some family time. as i have set first print of the day going. more mask frames. got to cut some buttons.
Been struggling to do much today but have taken a reading on my CR-10 figured out it 100k thermistor found this chart as is am seeing around the 144.9 figure. so around 17c will take a measurement later as its on one of our storage sheds and the tumble dryer is running to make sure this is changing temp correctly. I have put a thermometer in the room to give an estimate of temp as the bed should be colder.
he chart below is just to help others
So tonight will swap over the control board with the one i have been given and then see if we can get this all working before i turn my attention to the Prusa tomorrow,
got 200 screens to cut tonight once my boys in bed and going to do some more buttons have cleaned and made ready 225 night before last ready to ship out.
see how time goes as got to some filming for my business as putting together some how-to videos for products.
Will update later after eaten and little one has gone to bed.
Time to take a CR-10 to bits one more time hopefully for the last time of the week. wish me luck.
swapped over the motherboard reflashed the new board and still, no joy time to ask for help have emailed TH3D as they are the supplier of my levelling probe and ezout sensors.
2 hrs of my life i wont get back lol.
going to call it a night.
Sorry for lack of updates busy 2 days cutting printing and trying to fix printers.
have been looking over marlin config files have found a line of code that i am going to try \\ and see if that solves high temp ambient heat.
bitten the bullet on my prusa mk2s mmu going to upgrade to mk3s as then will have 2 reliable printers. 2 to 3 weeks wait but will double my output.
been playing cutting speeds as 1hr 30 mins to cut a sheet of buttons is too long going to cut faster with more power and have changed power and speed on engraving so should be 37 mins per sheet. will test later as want to get the buttons out.
Some images of last night.
more coming later.
As i have ordered the upgrade kit i will need to do some prep before the gets here in 2 to 3 weeks so i am going 1 disassemble the mks2s mmu and salvage 5 motors and 2 pulleys with bearings the lcd screen and surround. i also have a 19hr and 15hr pteg print for parts needed will cover this soon.
Have printed 14 frames today and cut 140 screens jigs starting to fail going to make new version as hav had some ideas. Also cut another 100 buttons.
Calling a night here.
Going to attempt one more thing on the cr-10 before giving up for now might strip down the prusa tommorow and will start on parts for the upgrade on week end as want all in place by the time it gets here. So will just be a build. Might stream the build if all goes well.
Right it the end of the road for the CR-10 for the time being as i cannot find an answer so into the attic it goes. got 4 sheets of buttons to run tonight and as that is going on will strip down the Prusa mk2s mmu and take the 8 bits that are needed to keep. rest will go into bag of bits as spares.
still printing ppe in the background though i will need to do a 19hr and 15hr print to get the bits for the upgrade i am in 2 to 3 week Que on Prusa website but like to be prepared for the arrival and have everything in place. more later.
been bust have stripped most of the bits from the Prusa mk2s that i need. till got to get 2 bearings and 3 motors but won’t take long to have all the bits i need for the upgrade. already studied the manual back to front.
I have decided to do first long print with PETG i am scared as never used it, I have heard mixed things about it. So have loaded some Prusa PETG it into the machine and embarked on the black bits for the mk3s upgrade and so far so good.
monitoring it remotely from my lounge as finishing off 77 more buttons.
Will go check with it later on before i go to bed on quality so far so good.
right time to sleep. blog tommorow
Afternoon all just a quick update printing going well 14hrs in to 19hr print.
Next up the Orange or in my case translucent red for the orange parts and new then new knob and LCD screen surround. that i have just sliced ready for print. all sliced for a 4hr print so around 40hrs of printing for all the parts needed to make Prusa printed parts for upgrade.
Back on to button cutting later 3 more sheets of 77 buttons to complete and i am up to date.
Right done 2 sheets of buttons done just need cleaning. The black PETG parts all done not sure i have to redo the wire support part got to load the stl up and have a look. then took my red which is violet translucent wow.
Had to be done so halfway through a 15hr print then final 4 hours of new LCD screen housing. Right I am done for today.
I have been busy cutting material patterns for my wife side project.
Made some more studio lighting for overhead filming using led tape and dimmer switch.
Getting the old printer ready been a fun little side project still cannot believe what is going on in the world today.
Hopefully Joseph Prusa will pull it out of the bag nice and quick. 2-3 weeks hoping for more like 2.
will be back on PPE tomorrow happy that i seem to over come my fear of PETG.
going to try having a early night.
Morning all well 2 hrs till the next plate of parts are done. then just the lcd display surrond and controls knob so in around 6 hours should be all done.
The last sheet of buttons todo today then going to cut some more material for the wife as she is making rainbows for NHS back later.
Well another full sheet of parts for the incoming Prusa upgrade kit. one more 4hr 19min print and i am done till kit arrives right time to clear the bed. make some breakfast.
19 seconds time laps of a 15hr print for your entertainment.
Morning all another day finally got all parts printed for Prusa upgrade just printing a wall-mounted spool holder as my broom handle isn’t working as well as i would like it, so as i am on a roll with PETG i thought why not do a wall mount spool holder for the smaller spool hole so now 3 hrs into 7 hr print. button production is all done just need to go to the post office and post them. if rain passes will go for a family walk.
Nearly done at 90% then to mount it to the wall and print more masks. been looking at the nyloc mod going to do some more research on it but might be a good one to do.
have also figured out my camera mount is not good for tall items see image below.
More upgrades going on if they all work then repeat for my ultraviolet Prusa Edition going to do the nyloc mod as looks like will help make on making the bed flat. Done using a plugin and manual adjustments looks good. I have ordered bits so i can do it. have also ordered some bits
so what mods am i printing well i have had to print a new guide for the filament as been warn away with my makeshift broom handle spooler. I printed a new one yesterday and forgot to post pictures must be losing it. Well, I installed it and has some issues with it so adding some wall management and pulleys to aid filament supply to the printer.
New camera mount came out great. waiting on magnets 6mm x 2mm should have them tomorrow as then won’t suffer from bumping camera and have a fixed rail so can move up and down.
New filament guide in PETG came out great as well so now have smooth feed.
Filament management is currently on the printer should finish at 1am so wont be waiting up on that one as going to bed soon.
parts are on there way for this so tomorrow will be a day of pictures have managed to produce 6 frames today but had 2 failures down to filament snag so stopped to get this working.
Right early night for me i hope. seems to be 2 am every morning. will post images tomorrow. once i have had 5 mins to edit them.
Been another busy day doing day job got parts in will assemble them later and post more images and information later. just got to strip down my racking of heat press as not doing any sublimation work in this climate so will put it in the attic till I’m back doing sublimation work.
going to so some spring cleaning tonight as i want to get my cnc machine working. over this lock down period so going to go through my draws and clear out part i m not going to need a box them up to come back to later. clearing up space so i can get on with fun stuff to entertain you all and learn stuff in the process. I have been prommising my 2 1/2 year old a door sign so will star with configuring the cnc milling machine and see how i get on. seen some nice printed projects for bit for it that i am going to make. will also be printing a dust cyclone.
Go back to printing ppe masks tonight if my modified spooling system works.
Was a non-eventful night as having had some issues with z height was late so-called it night not sure whats the issue is might be as moved printer going to have a play this afternoon after work as need my full attention.
Back printing was too much tension on my spool idea so have done something that will work for now will do some changes over the next few weeks gives me 2 materials per printer. will show images of half the system in place later new camera mount works very well going to install a dimmer switch to take off the glare fromled light on the print bed.
I am going to be setting up separate lighting and PSU power on for each machine so i can turn lights on and off independently on each printer. the will both have Logitec C270 cameras monitoring them. with octohub reporting on progress.
need to take current relay module and put in a different housing as its all open putting my HSE hat on don’t like unsafe stuff.
think i spoke to soon as print failed argh going to do some more testing. have lowered the z height .05 let see if that fixes it. gone again going to do some more testing as thinking there something going on somewhere. will investigate later
I do not know what’s going on but will be doing the nyloc mod tomorrow as need my printer back. going to lock up and bed methinks.
24hrs later and my machine seems to behaving so having a stay of execution with the nyloc mod.
as its been 2 weeks since i orderd the up grade kit i am starting to think ahead of what will be needed to be done so. i will be printing ppe during the day and doing mods for set up over night.
So first up is the lighting of each printer. so each machine will have separate led lights going with dimmer led tape as easy and cheap. have a shelf width 600 x 900 there’s a bar in the middle of the shelf so have two rectangles of 450 x 600 each will have 4 strips. i think i will inlay the light by 65mm all around the rectangle so tonight’s operation will be to take the shelf off and raise it by one link so i can fit the spooler under the shelf then my 3d vacuum sublimation oven can go back above it.
So have sketched my idea out in fusion 360 i will then tape the 4 strips to the under side of the shelf i will link them with wire final connection will go thought the shelf so i can attach to psu and relay.
when next print finishes i will do the fist part of this by setting up the strips and soldering them. once this has been done i will start on making custom pcb to make the circits for the 2 lights there will be a dimmer controlling both sets before relay controls them independently.
so the set up will have a raspberry pi 3 on each machine controlling power and lamp each set up will have a web camera. and a bar to control the height of the webcam. this will allow me to do awesome time laps using octolaps.
as its hard to visualize will show some images later..
Right my light rings are done and old spooler put back and new pulley system for guest filament. i have also done the other side of the shelf ready for the incoming mk3s kit.
I decided to go 80mm instead of 65mm from the edge and drilled centres out for pully both machines. As both machines will have a guest filament input this if for the odd shape spools i get from time to time, in this case, it the BQ filament that i am running PPE on.
I started off by getting my shelf off racking and marking it out before cutting the led tape to size and sticking it down. i then tinned all the pads on it and started to solder link connections.
All done back on with PPE production for the night testing how the new spooling system goes
I then added a second bar for the camera mount as i had raise the shelf by one so i could put everything closer to the printer.
Lower angle makes for clearer picture for remote monitoring and octolaps.
Right time to get some sleep night all.
Morning all going to be another day of printing PPE with a mix of wiring and printing.
so my jobs list for the day making 2 custom raspberry pi wiring looms and then 3d print 2 relay enclosures. I will then will move my raspberry so everything is mounted on the shelf easy to perform maintenance. I will also be doing some better cable management. so by the end of the day, everything should be in place for my 3d printers rack. Apart from the second spool holder, That i need to print and the second printer which i am hoping will be with me this week or next.
here is a system layout of my octopi setup. that i have put together.
First, up will be crimping some wires so will be making a link to relay module power connection to the enclosure. going to need 4 wires for the link to module going to use red and black for power. yellow and green for relay activators yellow for PSU and green for led lights.
Right Relay housing is printing in PETG looking lovely it should be done in a hour have started to plan the wiring loom but still just need to pen to paper before getting crimping tools, wire cutters and possibly soldering iron. will make 2 the same as then every thing will be ready just to plug in the printer and go.
then got an 8 Hr print this is the first parts for the new printer’s spool holder will print the base tomorrow and the rollers as well if time permits.I have built my new camera mount for the machine yet to do an Octolaps print might do that tonight to capture the base of the spooler being printed. Great design as held in place with magnets works well with my racking.
Just finished mask number 32 for the last week. have got 3 bags of masks of Nik and Celab to sort and box up ready to ship.
Going to wait for the current print to finish and i will start the next one going and then going to try getting an early one as every time i sign off end up being up to 2 am. eek, too fast layer sift start again.
Morning all was another 2 am as had a layer shift as forgot to slow the print down as PETG and not PPE so had to start over round 23:30 as i was about to go sleep noticed it had finished printing so jumped out of bed and cleared off print and started 7-hour print. finished this morning. so was able to start back on PPE run first thing this morning so will be running them till around 8 before i change back to PETG and do rest of part for spooler as the current one is white might reprint that as well so they match the machines so violet and black for new machine and orange and black for the existing machine.
over night parts came out great
Going to test out the new relay housing and remove old one off the wall transfer all the wiring over going to also move the raspberry pi and do first of the 2 looms tonight figured out the circuit.
Well that was my evening plans cut short as the relay enclosure dont fit the relay. not to worry I have some relays turning up mid week. So will see if they fit other wise will have to make me fit. so just printing base plate of the spool to fill time tonight i moved the camera so time laps is going to be not good. might go move it
Been out at the office today so left a big print on the printer to keep it busy going to bug Prusa tomorrow as will have been 2 weeks already since i have ordered my printer.
Will post a timelapse later. Still waiting on parts to arrive should have relays today at some point so will get on with wiring later IF they show up. let down by amazon so will be a night off tonight.
well you know me just doing some prototypes for our daily crafting project and printing solder fingers makes joining wires a lot easier.
Just pressed fitted bearings into new spooler got to gut 180 mm of 8 mm threaded rod and put it all together. really need to buy a vice.
Well ordered a vice will go pick it up today from screw fix click and collect so i can finish off the spooler, and mount it on the wall.
some images from last night as dident get around to it last night.
well, new relays fit with some trimming down of enclosure got my vice cut the bar and assembled new spooler for the second printer. and started second octopi build.
Think first sign of madness is setting in as named my printers and even created custom logos for them. so now features in my stream.
08/05/2020 1;41 am
One day will go to bed early, been busy making looms done both sets of raspberry pi GPIOs looms to 2 channel relays. will post some images tomorrow will write updated GPIOS as went with 12 pin connector makes for a more compact loom. Right time to sleep. tomorrow I will do lighting relay loom and prep second kettle leads to go through the relay to control on/off power to the printer.
the joys of a 2-year-old am up and first print of the day is on as promised here are images from last nights wiring will do a full schematic shortly. as I need to write it all down. oh and test it all before i publish it.
next up is the relay power side this will control printer PSU and LED lights. Word of warning you are playing with 240 volts don’t do this unless you know what you’re doing. #
going to start off with the led wiring going to need to put the live throught the relay so nc and com. so first off goint to wire up 2 jst connectors from the shelf down to printer shelf.
so out with my new tool i printed solder fingers so time to solder the wires and heat shrink. them. now i have extended the wiring i will join the negative wires into the 2.1 x 5.5 power connector on the positive side i will run 2 wires 1 to each relay com connection then 1 wire back from nc connection on each relay this will connect to the positive connection of the led lights. this will be wired into relay 1 of the 2
Right to get this to work will need to install the enclosure plug-in in octoprint and configure a light on gpio pin 12 this will allow you to set it so the when you start a print the lights will power on and then wen the print completes i will turn the light off. will add images later. once i have done it.
Power side i have taken an old kettle lead i have stripped the isolation off 4 approx cm of the wiring an cut the live. wire i then strip both sides and add a pin connector crimp so will make a nice connection in the relay. the 2 live wires are then put in pins com and NC on relay 1.
On the octoprint setup install psu plug-in and configure pin 11 to trigger power on and off again this can be set to turn off the printer after a print completes.
I will cover this process in-depth later on once done with wiring done. wont go over building octoprint set up as have done this on prior posts.
Right wiring done tested had a issue that turned out to be a blown fuse so will put the relay wiring back together and do cable management tomorrow back to printing one more set of frames. at least I know it works,
so what you going to need to do this.
- 12 pin dupont connectors
- 4 pin dupont connectors
- 10 female dupont connectors crimps
- Crimping tool
- Wire cutters
- heat shrink
- soldering iron
- octoprint set up
- raspberry pi 3 onwards.
- pin crimps
- pin crimp tool.
I am not going to talk about how to set up octopie as if you search here you will find a guide on that. this is to presume you have octoprint installed and up to date.
you are going to need to install the following plug-ins
- PSU Control
- Enclosure plugin
the connector i am wiring up is using an extra 5v+ Ground for the cooling fan so that’s optional. just google PI 3 GPIO and you will figure out where to plug in the connector below. white squares are unused pins.
12 pin dupont connection
- pin 2 = Relay Vcc +5v
- pin 4 = Fan + 5v
- pin 6 = Fan – Ground
- pin 9 = Relay Ground
- pin 11 = GPIO pin 11 PSU on/off trigger
- pin 12 = GPIO pin 12 Lights on/off trigger
4 pin dupont connector
- pin 1 VCC Red wire
- pin 2 GPIO Lights Trigger Green Wire
- pin 3 GPIO PSU Trigger Yellow Wire
- pin 4 Ground Black wire
connect to duel relay board match vcc and ground. on the relay 4 pin connector
relay 1 is PSU power so will need to split the positive connection to the live feed obviously do this when unplugged from mains voltage.
Insert one end of the split wiring into com connector and the other into NC (Normally Closed) and screw tight.
Now for relay 2, this is where it gets a little hard to explain but i will try my best i have a screw terminal 2.1 x 5.5 power connector female have joined te 2 negatives from both sets of lights to negative connection. the live side has 2 wires joined together one for each set of lights each wire goes to each sets com connection then the NC side has the positive wire from the led lights so each relay has its equivalent.
right to make my ramblings more legible have done this wiring diagram.
all wired up. now to configure the software side.
fist up click on psu controll in configuration set the settings as set below.
no scroll down. To power offer, i have mine set up for longer at the moment as keep going in and out to take prints off the bed. but if not usually set the power-off time for 30 mins.
going to look in to sensing as GPIO pin options as might make things easier as when it turns off using commands usb port times out so will see what happens if i use gpio method over comes that.
Next up go to enclosure plugin
label in my case is lights.
I am going to investigate other features in the future. As print start to turn on the lights and 30 mins after the print ends will turn off lights. in theory. will try that out tomorrow.
system should be working now. will add more as i do it.
Going to be a busy day, will continue guide above first print of the day is on the printer when that is done should be son’s nap time so will do some cable management going to move printer out. then run all the cables stick the relay housing down and screw the pi enclosure to the wall. i will then refit the printer and continue printing and repeat for the other printer space so when it’s here can build install and print.
Was mother in laws birthday to day so time has been limited to running frames will do the install tomorrow instead. have been updating the guide above will finish the software side tonight.
Right guide done as far as i am i have done it. will do cable management and get everything neatly installed and then can continue with a clean up of the workshop as want to get my CNC machine running before this lockdown ends as i have some jobs i wan to get done. tonight i am going to call it and have an early one.
Morning all wiring tiding day once little one goes to bed.
Managed to wire and tidy up t printer. however, it keeps on popping fuses think i might try 13amp fuse. as all wired correctly but here is some images for your enjoyment.
I have wired the lights and mounted the pi to the wall just need to add the webcam and the USB cable network cable and make the mains cable up.
but back to frames as the need to get some shipped out tomorrow as starting to fill up my workshop. also need to finish filming some shorts for my day job. so need to get worktop clear of bits that i have taken off the shelf and move my vacuum press back into the workshop. will do more tonight.
I Have been out doing day job stuff printing frames in the background. I am just about to speak with Prusa to find out when i will get the second printer. Tonight i will clone octoprint to the second pi and install USB cable and camera. will also install second power cable and test it all then that rack is done. Ready for the printer.
I will be shipping off some on my sublimation printing stuff off to storage to give me a little more space as we don’t need them for the time being. took some airsoft bits.
I am going to bag up all my guns as don’t think will be playing for a while.then can put water pump bucket out freeing up shelf space as really want to get CNC machine working. did have some thoughts at the failure of my previous attempt. So hoping by Friday to be all set up ready for some fun projects i want to do.
Prusa bad news got a further 3 week i will need to wait for the new printer oh well everything is ready for it to arrive. just need to up t it all together. just cloned my PI sd card now writing it to a new sd card for another setup. will then change the theme to violet. going to change the titles to there names. NEON ORANGE and ULTRAVIOLET think I’m going crazy in the lockdown.
more spring cleaning and frames tomorrow and a trip to the office. more videoing for day job. After wife’s birthday is over on Wednesday will start playing with cnc machine.
Not a lot was done today clone sd made just need to install it in the pi and power everything on but that will be later on this week then just need one more trip to storage to put some more stuff over there i will then be able to get the CNC machine up and running hopefully.
As i don’t like having equipment i cannot use taking up space and this is a very expensive paperweight.
Another day in lockdown but it is my wife’s birthday so will busy today first set of frames are being printing.
As i was clearing a print off the bed have put second relay together and stuck it down. and stapled gun the mains wiring down just got to run USB and camera wires and power up to the pi then will boot it up and configure all ready for the printer when ever it comes waiting on 2 pulleys as well then this little fun project is done will copy guide to its own post shortly.
currently playing will it or won’t it print on the filament left on the spool getting around 89 frames to a spool i think. so just waiting on my phone to let me know when the print is at 50% to do next check as the Prusa don’t like it when the filament gets to the end tends to do a jam in heat brake. so just monitoring remotely.
Right calling it a night last prints on of the night. didn’t finish wiring up but tomorrow is another day. in the world of lockdown wife loved my crafting project added lighting to a vintage stage door sign. love led tape my soldering iron and
printing printing and filming for my other business. tonight i will be fixing a lamp might document that for fun. anyhow back to filming more updates later on finishing wiring up stand 2 for printer.
right was filming till about 2 hrs ago just been editing for my business will get more done on the blog tomorrow as just got to do some place holders and film rest of filming scheduled.
But then will get on with fun stuff over the week end. CNC machine is my goal.
afternoon all HAPPY FRIDAY. have been busy with work this morning just had to pause my mask production for 5hrs as printing an endoscope stand to aid with close up filming of products. got to love petg such a nice material to print don’t know once i have run my PLA down might just print with it from now on.
Nice new camera holder works well will be great for close up shots. see below. some m3 screws and nylock nuts holding it together great design can be found here. i have made some mods as its not meant for my smaller endoscope but some tape it works well.
Bad news the UK government has changed ruling on PPE so looks like down tools for the moment will keep you posted.
As PPE production is on hiatus i am going to start with my CNC machine this evening. going to start basic and make a square and a circle basic but need to get my head around it once i have cracked that i will try more complex stuff.
So first up i need to clear my floor space and remove all airsoft bit bits as i don’t think with COVID-19 i will be playing anytime soon so going to bag them up and put in my top shed to take to the storage unit tomorrow.
I will then clear CNC machine enclosure as been using as a dumping ground need to go through it and see what’s in there.
Once i have cleared that going to move wiring and vacuum around and control box for CNC machine as this will allow for 2 more storage boxes for materials.
tools down issues with my laser think its a limit switch.
Morning all well today i will be investigating my laser as need to get back up and running have ordered a new switch should be with me by Monday but here for your entertainment is a 19hr lightsaber timelaps.
Morning all got last last night so did not get a chance to update my post. lasers back up and working was a lost connection on the stepper motor driver.
Will be moving things around today. and finish off wiring loom for home and limit switches for the CNC as i want a working CNC machine. decided to print another lightsaber with removable core but it failed so going to reprint that today. anyhow back today job. more later.
print failure argh 2nd failure thought i had cracked it with a brim but no, I think i might try something else next.
3rd attempt 20mm brim as its got very little surface area.
Right clean slate all stuff shipped off to the storage. So now clear to film and get up to date with day job.
In my spare time will start to look at the CNC machine this week. just going to rotate it 180 degrees and re-route wiring and water pipes re plum cooling bucket and aquarium pump. thinking about giving its own PC to run Mach3 off.
As the last time i started playing with cnc machine i stated running the limit switches and z probe wiring i will need to finish off loom with a quick connection of some sort.
So i am also going to have a quick go at mounting limit switches. past the point of return so time to modify the machine.
As then it’s going to make my life easier as will avoid bed crashing. whilst i learn how to program it. should be a doddle but just for some reason or other not got my head around it but to be fair time was not on my side the last 2 times were as this time every day is the same.
This is my next project in the workshop.
Coming soon as they ship it will be doing a full upgrade from mk2s to mk3s Prusa i3 as been delayed by 3 weeks at least. so some more fun coming up. to keep me sain in these strange times.
Morning all right all coffee up and ready to face the world.
Print failed as the dreaded 50% just as i was going to sleep so stopped it without a drama. will revisit this later on as 3 failures is enough. for me to re-slice it and try again.
First up going to print an end stop bracket system for the CNC machine and a vacuum and light system as well. so out with a roll of petg. i found these on Thingiverse last night.
Not sure its 100% right so going to print in pla and then if it works will do it petg. all sliced up and sent to the printer.
all printed will test fit after run to post office. and boy has gone to bed.
Sorry for not posting yesterday was a full-on day of sorting stuff work-related as for previous parts i printed long a short of it don’t trust parts off Thingiverse anything fitting correctly as not all 3040 machines are the same. so last nights idea been playing with limit switch holders. I think i am going to mount directly to hardware using a clip i have remixed. will post images later as very hot in the workshop today,
just going to take some measurements and look in how to sort the z axis measurements. and toy with ideas on how to mount z fix switches to the machine might need to design something. after looking over the machine i decided i would mount front and size
Going with my remix idea and tabs that i have cut down from bits i printed on Thingiverse that didn’t fit so got my side cutters out and cut it down to act as activation tabs. have used some double-sided M3 tape to hold in place to make sure all works will then drill and affix with M3 screws once i prove it all works.
switch X- is not making contact so i am going to have to drill it so i can slide plate across as its catching on the z switches making contact to the frame before microswitch. not an issue though. will drill and tap it. i will wire all up then will super glue switches into brackets once i have tested everything.
but that will be after the sun goes down. and my little boy is in bed. as i will need to drill some more holes for the Y-axis switches run wiring in series to all the switches and back to control box. then configure mach3 to recognise the switches then should be able to home and test.
See how we go later that what i am hoping to achieve today. Then tomorrow can be wire management and first test program to check all axis’s are calibrated. also need to drill the wast board. and mount it to aluminium bed. I have gone with a thick first waste board as i don’t trust my self.
I know you all say well you have a laser and 3d printer this should be a doddle well its been my kryptonite since buying the machine. fingers crossed this will solve everything and get me up and running.
Little tight for my drill going to need an extender bar to drill and tap second mark. also need shorter m3 screws. I also marked out drill hole over top of channel so i can ge some bolts through it to scure wast board. will do the same on the back of the board tommorow as well. Amazon is my friend parts now on order for sat delivery.
So M3 tape to hold it in place till then. I will tap and wire the bottom Y-Axis 2 micro switches tomorrow lunch. going to add some quick connects for wiring. This is going to be wired from in2 on the controller board back to the ground in a normally closed loopback. i am using in4 i have connected for z probe as if its there i might as well use it. going to use a quick connector for that so can zero tool on the material.
I then will feel a bit more confident to start playing with it. As at the moment is a scary bit of kit.
Have been looking in to things a little more and now think i have the answer to what to do.
As with mach 3, a home switch can be a limit switch as well. will wire homes switches as -X -Y +Z and limit switches will be +X Y+ and -Z i will also set soft limits in the software to prevent E-stop activation.
as the way limit switches work they will activate E-stop if hit. but with soft limits will slow down and stop before hitting switches. the home switches will also act as limit switches after systems been homed.
so my set up in configurations of mach3 will look like this.
I will then configure the soft limits this will prevent it from ever hitting the limit switches but just incise they fail its better to have them.
I Cannot set these up till i have wired up all the switches in place hoping to do this at lunchtime. Back, later on, to get everything ready for testing.
should not be allowed near tools drew blood but drilled out the base for micro switch holders.
drill taps snapped so have had to re-drill going to use nylon nuts and bolts to hold every thing down got to strip the bed off now the joys of life.
more work tonight before wiring will post updates later.
Prusa upgrade kit shipped. should be with me on the 28th of this month.
I will be wiring up the switches in series in sets of 3 so 3 switches on the home side and 3 for limit side. will do a diagram some point over the next day if it all works. just having a sit down as its been a full on day with little one.
right going to do this tomorrow as now figured out my wiring loom is short by 200 mm.
all brackets mounted just need to solder it all put it back together but happy with progress just wish the man cave was so hot atm 35c back in the morning. night all.
Morning all just been putting together some test patterns in gcode for the CNC machine. going to cut a circle outline and hollow out a square to make sure its calibrated correctly. once i have done that i will start to play with more complex designs.
Waiting on my wife to get out of bed and boy to go to sleep then i can get on with getting my 3040T up and running. want this all finished off today. As then can get ready for the delivery of the Prusa 3d printer Upgrade kit from mk2s to mk3s. but that’s later on next week.
Been a productive lunch time nap time for me, CNC machine all re assembled z homes correctly x and y are in reverse i think i have just fixed that will test shortly and come back to you all. yup all fixed.
now to set up soft limits to stop it crashing in to limit switches.
Right now to test the soft limits out and once there tested i will then test the probe tool once that done. i need to plum in the cooling pump and water put in waste board in then i am ready for test program. fingers crossed will add images later.
Paper weight no more all working over the moon going to try making something proper tomorrow. Just did a simple pattern but homes and limits work.
Have moved it back in to it enclosure re installed the wiring . then cut the test pattern again to make sure all works. and was not a fluke.
It all works bar the probe but that probably something silly. think i might add a camera as well for help with setting it up.
Anyway enjoy the images of the last few days. Last
Right done for the night tidy up in the morning so happy it works time for some fun tomorrow.
right been busy making a sign for my boy’s bedroom well first attempt at a sign I have managed to break my first end mill 2.0mmm well my fault as went really deep and was trying to cut 5.0mm in 1 pass.
so now going to cut in 5 passes using 2.5 mm end mill as don’t want to risk damage. going to cut at 1.0 mm per cut. also getting some ripping on the cut so going to limit clear out to 4 passes. actually preview shows its not going to clear out so will set up everything ready for tomorrow.
I have repositioning the control box as then can keep the vinyl cutter in the cave, I have put the control box next to my sublimation printer. all neat and tidy.
i had a look throught the dump bin of cnc parts i have on the wall and there was 2 more 2mm end mills so i take it every one brakes them at the first attempt. so will run the program again tonight. its a 4 part program so using 4 tool changes.
So program one material removal with a 6mm end mill. then tidy up and clean out with 2mm end mill followed by a 3mm end mill to drill mounting holes. then back to 6 mm to cut the sign out i have left tabs so it won’t flip out. going to also add edge finder scripting to make it al the more accurate tonight. more later.
Roll on making more cool stuff still buzzing from getting things working. right now to finish off the clean up of the cave. then will be ready for prusa build later on in the week. will put a go pro in to film the cut later if all goes well.
Lasers blown a connector so going to be down for a few days. I’m nearly all done in the cave just some more wiring and we are good to go. going to play with CNC coding over the next few days. till the Prusa arrives .
Also going to look at making a dust shoe and finish the enclosure off think some hinged perspex or something similar keeps the dust down and the noise. but got the cnc bug.
got to figure out how to film it for you enjoyment.
Been busy printing dust shoe for CNC machine. i am awaiting the brush material for it should be here tomorrow. 1hr left on current bit the shoe adapter left to print. next projects engraving 3d on the CNC. I probably need some better wood samples. as only have mdf in my stock bin.
dust shoe printed and fitted need to drop the spindle down a little bit and got 70mm brush tape coming tomorrow think i will need to upgrade my vacume but will know more once its fitted fully .
Also fixed the laser was a burnt out plug managed to make a new one out of parts box till i get a new six pin connector. So it then made wife a storage craft box to test out the machine.
Last of the cleanup tomorrow and getting wiring all sorted for the second Prusa so can plug that straight in and then i am done on maintenance time to start looking for new projects my arcade machine i on hold till i can get back to wale.
Might do a design for the CNC machine to cut. to test the dust shoe nothing fancy just something see how it clears a path also want to install the edge finding script and centre finder. will do a review on my 3040T now that i have a working machine. going to superglue the micro switches in place tomorrow as well to stop slippage. right night all.
