I’d contact @OnefinityCNC. I’ve no memory of seeing that one come up on the forum.

Have you investigated possible connection issues with “Z” axis’ motor? The cable has four wires terminating at both the motor and the controller. A wonky connection on any of them will cause a motor fault.
I added a little more ‘hot glue’ on all of my cable connectors to make sure none of them flexed at those junctions as a just-in-case.

The connection line is normal. When I connected the z-axis motor to the x-axis motor, the motor moved and stopped moving. Perhaps there is a problem with the motor.

6

If the motor moved then stopped it doesn’t sound like a motor problem but the z-axis cable. You could try it again while gently wiggling the cable at each end to see if that makes it stop moving.

I think the motor is defective. What do you think? Please refer to my YouTube video.

The fact that the z-axis moves (shuddering but moves) indicates it is probably ok. (The reason it shudders when connected using the x-axis controller’s output via the x-axis cable is because z-axis does not ‘pin-out’ the same as the x-axis cable.) The z-axis has reversed wires relative to those in the x&y cables. I had forgotten that fact when I suggested troubleshooting using the x axis cable because I have drag chains and don’t use the stock curly cable.

Try hooking up the curly (z) cable again then gently wiggling the connections on each end while trying to move z+/-. If the motor starts/stops you’ll know which connector is the problem.

Note though, the z motor’s pigtail connector could also be suspect as well as the curly cable.

100% you cannot have the x rail directly connected. You MUST use the curly cable for the z. There is a wire cross in the z curly cable…and since there isn’t one in the straight x cable, you’ve now crossed wires to the motor…which could lead to a motor failure. Hook the z curly cable back in. Hopefully it won’t give you an error. I fear you might have done damage by directly connecting the x cable to the z.
