My first thought would be that the stepper driver isn't providing enough current and the motors are skipping steps at different rates. Turn the potentiometer on the stepper drives up a little and see if that helps.

If that isn't it, post a more specific description, pictures and if possible a video.

What happens is, my z axis is moving then one stepper stops and the other one keeps going.

Thanks

Hi I fixed the problem i just wanted to let other people with this proble that when the current is set correctly and one sstepper stops and the other one keeps going, just put some super lube or something like that (grease, oil, etc.) on it, it relaxes the nuts so thats the steppers dont have to use so much torqe.
