I figured it out, there was a rouge piece of Gcode in my homing file that enabled stall detection at crazy high sensitivity so every time it moved, it paused, stalled on the pause, and resumed. Thanks almost everything works now!
Good point, the tpre should allow extruder movements. Is there a way I can change the firmware myself or do I have to wait for the next release. Thanks
I am wondering whether there might be a short in the PT100 cartridge between the element and the casing. Can you check it with a multimeter?
My own PT100 is connected to the Smart Effector, and from there in a separate 4-core cable to the Duet. It runs parallel to the extruder motor wires for a short distance.
