there's a weird problem with my A30.
After homing, the Z engine turns on the right side opposite to the left side
and the right Z motor rotates after contact with the end stop only in one direction (in my case down), even if it is to be moved manually in the other direction.
This causes the Z axis to skew while homing and there are very nasty noises.
I hope someone can help me with this problem.
UPDATE:
I've found that the z-axis stepper on the right side only turns counter-clockwise. It does not matter if you let the Z-axis go up or down, the right side always turns in the same direction.
If I put the right stepper on the wiring of the left stepper, the stepper runs perfectly.
I have already tried the following to solve the problem:
- Stepper drivers swapped among themselves
- new firmware flashed
- new cable used for the Z-axis right stepper
unfortunately all without success
