UM2Extended+ not heating


Recommended Posts

Posted · UM2Extended+ not heating

I have just acquired this machine and the hotend will not heat. The hotend heat cartridge is not open and I believe the control board is the issue. So without purchasing  unassay parts, I have ohmed out the cartridge and is is not open, tested for output voltage on the control board HEAT1 but got 0. My question is can I used HEAT2? I have some experience in Marlin and can re-assign the pins, But is the Marlin firmware the proper firmware to use on this machine, as I can not find UM firmware that is in a base code, I can only find the HEX versions. Any help would be greatly welcomed..

    Ultimaker firmware for the UM2.1 Extended can be found here:

    https://github.com/Ultimaker/UM2.1-Firmware/tree/UM2.1_JarJarExtended

     

    Double check the heater cartridge to not have a short circuit, otherwise you will break the switch on the control board.

    Changing the HEAT1 output to the HEAT2 output is possible by changing the pin numbers in the file pins.h
