Anet A8 extruder motor moves back and forth
This is what is happening to my motor. Any suggestions would help.
1. I have tried adjusting the trimpot.
2. Rewire the connector to match the one on the motherboard.
3. Anything else I found on the internet.Low-hanging debug options: 1) connect the stepper to the driver of another axis 2) swap cable with another stepper/driver combo. The behaviour will allow you to understand what part (cable/driver/stepper) is at fault.
What Mick said was exactly the issue. Went to check the continuity between all of the wires and found out that the black wire didn't have any. So I took the black wire out of the connector to take a look at it and the wire just feel out. It wasn't even crimped. Once I recrimped the wire and tested the connection. It works beautifully. Can't wait to start printing. Thanks Mick!
Check the continuity of the wires on the cable. Sometimes, they are not crimped correctly. Another common fault is crossed wires. In either case, the easiest diagnostic test is to substitute another cable, but please note the color coding of this replacement wire to match the cable you replace.

Does it continue if you ask an extruder move from the control panel? I think I remember this behavior from my electronic courses where a stepper motor was halfway from a step and sending a move command did fix the issue. (no guarantee, my memory could be faulty)
