Hi, been running a CTC Prusa i3 for about a week without problems but now the extruder stepper will not respond to commands.
Swapped the extruder stepper for the X stepper and and extruder stepper works, X stepper does not work as extruder.
Swapped the leads over same result.
Swapped the stepper control boards over same result.
Any help pse
