Y axis moves but is sticky and make loud noices

I’ve got the Y axis to move but they aren’t in sync (moving out of square) and make loud “grinding” noises. any advice would be appreciated.

New build?
If so double check the Y wiring they are not the same for each side.


Grinding noise = stalled stepper.
I suspect you have one of the steppers wires incorrectly (reversed) as Mark is suggesting.

Each stepper have four wires, in which are two pairs (one pair per coil)
If you swap the “polarity” on ONE of these pairs rotation will be opposite.


yes new build. you’re talking about the wiring that runs into the x-controller right?

that was it thanks guy
