Whenever I try to do anything (start a print, unload filament, load filament, etc) the LCD shows the extruder stuck at 1%, forever.. even though the exturder is clearly hot and ready to go (smoke coming out of it from the filament burning inside).
If I fumble the connectors around a bit (cable and board) it works again for a short while, then the problem happens again.
Any idea what might be going on? Short circuit somewhere?
