It was working and now my extruder stopped working.
I connected my extruder stepper motor to z axis and it turns. This means the extruder stepper motor is working
I then swap out the z axis and extruder stepsticks (ramps).
I connect my extruder stepper motor back to extruder connector. motor does not rotate?
I know that the stepper motor and ramps are working. What can I check on the main board?
I know this thread is a little older, but since yesterday I have the same problem: extruders stepper won´t turn anymore.
I connected the extruder stepper to x,y, and z axis and the stepper moves. but not on its own place...
I swapped the pololus, all four are working,
@Dshiri1: did you solve the problem?
