This is usually a wiring or power supply issue.

I have ran it for a couple minutes and try ed homing it a couple times but nothing changed and it stayed +/- 0.01v so it might be the wiring

Come on you just wanted to show off your nice fluke aren’t you? :wink:

I think if the wires are wrong it should maybe report an open loop or closed loop. But check the wiring against the data sheet of the motor or just swap the motors if the others work fine.

That’s all the info we have to go on, so hopefully you find a problem in the wiring. I can’t offer any other advice.
