Just completed my UM2 Mark2 build. Ordered the PCB from aliexpress, just replaced the magnets to some better ones and wanted to print my first (single extruder) PCB case with the new firmware.
The printer heats up just fine, makes a little line with extruder 2 (which is strange, didn't select extruder 2 in the cura print file...) Extruder 1 follows the test line and the little poop. After that, both extruders cool down to standbye temperatures, so i'm not able to print anything... Am I missing some setting i needed to change??
I do get some temperature sensor errors, but after heating up the extruder with a heat blower, everything runs normally... (Cura 5.6 with the Mark2 Profile and modded nozzle files)
