CR-10 Firmware upgrade and new Bed install.

After my week end fun of rebuilding my machine and trashing my magnetic bed. i ordered a replacement glass bed with build material on it. an offical creality one.

So to make sure its not 2 of 2 beds destroyed in 72 hrs i am going to start off by upgrading the firmware and re positioning EZABL probe as i just fitted it and never ajusted it.

First things first a bit a prep work as I have a day job. So during my lunch hour I downloaded the latest version of the firmware off as I have an official EZABL sensor. is current.

I have unzipped the folder and then uploaded to my dropbox so I can pre-edit all the defined lines on the configuration.h part of the upgrade sketch. One thing to note I have pre-flashed my CR-10 with a bootloader go find a guide on how to do this first if you have not done it.

when you have unzipped the file you will see, OpenFirmwareWindows.bat double click on this file and this will launch the Audrino sketch pad. click on the tab

scroll down to your printer model in my case CR-10 then define your settings by removing the // symbols.

as you can see i have set mine to CR10 and OEM Probe Mount .

After making changes save the file and change the in my case I set the board to Sanguino 1284P in tools then hit upload will take a while to compile and then should say the following when done.

system will reboot after flashing

Firmware update all done.

Installing new bed

This was very easy remove glass bed lift it out new on in job done looks very smart. So far it’s works very well still dialling in the setting but Pleased with that it sticks well.

Probe positioning and sensitivity

the probe base should be 2mm higher then the print nozzle approximately so i ajust the the nuts to position it in the right height..

Then using the printer menu i go prepare> move axis>move Z axis>0.1mm enter i then lower the bed till the nozzel is touching the bed.

Nozzle touching the bed with probe 2 mm off the bed

I can now adjust the sensor sensitivity. turning the small screw on the top anti-clockwise till the light goes out. i then slowly turn it clockwise till the light turns back on. sensitivity now set. now I raise the sensor z-axis 2mm off the bed.

Nozzle 2 mm off the bed

Now I go prepare menu scroll down to preheat PLA and heat the bed up only I leave this for 5 mins. to warm up the bed so it’s up to heat. then using the same z-axis movement from the menu and a piece of paper.

I place the piece of paper on the heated bed. I lower the z-axis until there is a slight bit of friction between the paper and the bed. I note the setting of reading -2.01.

click to enter then go to motion menu
click to enter
click to exit then go up one screen store settings the you are done

I now exit back to the main menu and go to the control menu>motion>Z probe enter. I then set the setting to -2.01 exit up one menu and store settings. (the setting value will be different on every printer)

that is the z height dialled in now to run auto home and pre heat set up ready for calibration test.

The calibration test.

So going to run 3 calibration test first up is bed test 275mm this will draw 4 squares and lines and logo, this will be followed by a test cube and a torture test.

The 275 calibration test.

Did not run need to get calibration cube right first

The calibration cube test.

cube printed but as you can see there were some issues I have since levelled my z-axis as was slightly off will run again and see if I can get it better might just need the profile adjusted in simply3d I have also just upgraded to the latest version on S3D so will see if that corrects the issue tonight.

The Torture test.

Did not run need to get calibration cube right first

Summery of Monday nights activity’s

  • New firmware installed with out hitch.
  • New Bed Installed works well.
  • Probe hight and sensitivity all set up
  • Calibration need to try the new version of S3D if not need to tinker with settings or find a better profile.

Right looks like Tuesday will be fixing the issues with the slicer might run some new feet for the printer as well to get rid all vibrations.
