Hei,
The x-axis stepper driver burnt out (motor making weird noises on that stepper driver) on our UM2+, which is why I swapped the stepper to the E2 axis and swapped the pins accordingly in marlin. Previously we were using stock software.
Now I think I made the new firmware (marlin 2.1.2.1) work as far as homing and bed levelling and extrusion with e1. No unusual noises. Everything moves apparently in the correct directions.
The issue is now that when I start printing it starts up correctly (heats bed and nozzle, homing, move to front left, extrude some feed stock etc).. but then, just after it moves to the first coordinates of the actual print (in this case the skirt/base thing) marlin suddenly fails and reboots without any error message. I think it’s round about the line of of where I print “problems start…”
Any hints to where I could continue my bug search? I am guessing it’s still something that is set incorrectly in marlin.. but what? 🤷🏻♂️
Anyone? 🙂
