X axis problem
-
The X axis has started to play up.
When I press the controls it barely moves but has a bad grating sound, also when I home it it just vibrates on the spot. I have tried two different drivers but still the same, could it be the motor playing up

Sounds like a break in the wiring to me. Stepper motors spaz out like that when one of the 4 wires is disconnected. I would inspect the connectors and start checking continuity with a multimeter.
Here is some related information on stepper motor wiring.

Thankyou, yes that was the answer.
