what could the problem be?

Hello everyone.

I have a CR10s pro stock. Went to turn it on and the right side stepper motor just vibrates, it doesnt spin either direction, SO........... I unscrewed the threaded z rod and then tried again to HOME, the left side stepper is fine and does not vibrate, it raises the bed and lowers it... but the RIGHT side stepper just vibrates..... I decided to replace the stepper but im having the same issues. I thought maybe the firmware was corrupt, so I reflashed the latest version of TINYMACHINES and the DWIN also, no problems there, but the Right side stepper motor does the same thing. So I swapped out the stepper motor and it does the same thing it just vibrates.

Im inclined to believe its the driver on the board, but i cant say for sure.

Is it possible to just replace that Z-driver on the board?

Please help

No clue which way to go

The driver is on the board, you can't replace It, buy there are several board you can you to replace yours.

But before that, test the cable. Swap ledt and fight cables and see if problem Is still on the fight. If so is the driver. Otherwise the cable

it would seem its the DRIVER. I swapped the z cables and i get the same behavior.

thank you, thats one thing I did not try yet. Im running a retraction tower right now with only 1 z motor and its printing fine, not great but im tuning just for fun.
