@jderp check your wiring as its probably a loose or damaged cable

I can't believe it was as simple as that. There was indeed a bad connection on one of the wires.

Hi,

My Y axis is refusing to move, it's making a lot of noise and juddering back and forth, sometimes it moves in one direction but very loudly. The thing is everything was working perfectly a month ago when I last used my printer and today when I tried to print something the Y motor/driver just decided to not work.

I'm not sure if it's a faulty driver or wrong settings, but seeing as it was working perfectly it seems like the former. I have tried hooking up the motor to a different driver and then it seems to work perfectly. I've also hooked up the Y axis driver to another stepper motor and the same issue occurs where it's just juddering.
