Problem: Extruder not working

History: My extruder was clogged and I didn't realize it at first and I opened the extruder and pulled out the stuck piece but later I realized it still was not working. When I put pressure on it the motor rotates and the filament comes out but does not work by it self.

Try 1: Thought something was wrong with the gears so I reseated them, Didn't work.

Try 2: Thought the extruder motor broke, so I replace the NEMA 17 motor, Didn't work.

Try 3: Plugged the motor into the x-axis plug the motor works as shown here - https://photos.app.goo.gl/kY4okR4oqkYSyzhN8

This is how the motor behaves when pluged into the [original] extruder plug- https://photos.app.goo.gl/QPo7RNeB6AFi6KsM6

Any help is appreciated, Thank you :)

  • $\begingroup$ @0scar Thank you for your reply, I checked the cable with my multimeter all the wires are working as intended. My only thinking is the the board some how is damaged. Should I order a new board? $\endgroup$

It was the stepper driver, Replacing the motherboard fixed the issue.
