What firmware version are you running on the PanelDue?
Latest 1.23.1, i think. Same issue with previous Release.
How is the PanelDue connected? 4 wire cable, shielded, 60cm? Tried replacing the cable already.
Is the extruder wiring running alongside the PanelDue wiring?
Yes, but i have tried to separate them before Posting here.
How are you starting the extruder motor?
