Troubleshooting
After Firmware Version 3.12 Prusa introduced a new thermal model to improve printer safety - Due to the limitation of the 8-bit board a fork of the Prusa MK3 firmware was created to include the thermal profile for the 40W and 60W revo heatercores. The steps outlined below are required to setup up your MK3 to use the Revo eco-system effectively.
1. Verify the firmware version installed on your printer. To check this, on the printer's start screen, the firmware version will be indicated. You can also check which firmware version you already have via the following process: LCD menu -> Support. Scroll down, and you will see the firmware version.
If your printer displays a firmware version prior to 3.13.0 or it does not start with E3DREVO_fw_ or E3DREVO_HF_60W_ B we would advise that you install the latest Revo-supported firmware release via the following link and proceed with the next steps: https://github.com/prusa3d/Prusa-Firmware/releases
If you are using an E3D Revo firmware, please check that this matches the Revo Hotend you have installed, as there are different versions.
· For a Standard 40W Revo heater core, please use the. HEX file starting with E3DREVO_fw_ ensuring you chose the correct. HEX file for the printer model you have.
· For a High flow 60W HeaterCore, please use the. HEX file starting with E3DREVO_HF_60W_ ensuring you chose the correct. HEX file for the printer model you have.
If you do have an E3D Revo Firmware installed, and it matches the Revo HotEnd you have, please go to step 4.
2. Once you have downloaded the firmware Zip file and extracted it, please use the applicable. HEX file for both your printer model and the version of HeaterCore you have:· For a Standard 40W Revo heater core please use the. HEX file starting with E3DREVO_fw_ ensuring you chose the correct. HEX file for the printer model you have. · For a High flow 60W HeaterCore please use the. HEX file starting with E3DREVO_HF_60W_ ensuring you chose the correct. HEX file for the printer model you have.
If you are unsure as to how to update your printer's firmware with the .HEX file please refer to the Flashing procedure within the following guide: https://help.prusa3d.com/article/firmware-updating-mk3s-mk3s-mk3_2227
3 -Once you have flashed and updated your printers firmware Run both the PID and TM calibration from the LCD Calibration menus of your machine.
4 - If step 2 fails, however, please Use the Revo_Reset G-code files to force setting changes. There are 2 versions of this g-code that will need to be used based on the HeaterCore you have installed
- reset_revo.gcode: for a 40W HeaterCore
Reset-Revo 40W- reset_revo_hf_60W: for a 60W High Flow HeaterCore
Reset-Revo 60WThese files will need to be copied to an SD card and installed, to Install the G-code select it from the print from the SD menu on your printer and follow the on-screen instructions.
5 - Once the G-code has been installed re-run both a PID and TM calibration from the LCD Calibration menus of your machine.
