Is my X Axis Motor Broken or Faulty?

If you haven’t, please contact us at support@carbide3d.com

Note that the motors from Sparkfun will have bare wires, so you will need:

  • pins
  • new housings (if the old ones can’t be re-used)
  • crimping tool

see:

for specifics.

But, it’s not likely to be the stepper motors as @neilferreri noted.
