Describe your issue:

After changing my board to the m8p with the cb2 the stepper motors don’t work. I feel a slight bump when i try to home, but then they stop.
The stepper motors I’m using are the default ones that come with the e5p.

I noticed that I did not reset the run_current to the recomended 0.8, but that’s what I was using. I just tested with 0.2 to see if that was the issue.

Did you properly set the motor voltage via the jumpers?
The forth motor port is parallel to the third one and does not have its own stepper driver.

Do you mean set the jumpers so that the motors use the board power and not the high voltage? Yes, the jumpers are all on the same 2 pins, on the photo you can’t see the ones that have the stepper drivers on, but the others have the jumpers in the same pins.
I use the 3rd and 4th motors for the z axis, just like on the original board.

I figured out the problem. One of my stepper drivers is not working. Thanks for your help anyways.
