Hi All,

I have a new Rumba board. I have DVR8825 drivers on it. When I attach a stepper motor to it (x or y) and I try to move it it just vibrates back and forth and does not move. It just hums either louder or software based on how I turn the DVR8825 screw.

Does anyone have any ideas about that or maybe its the jumper settings on the board.

I cant find a manual on the RUMBA

Thanks Steven

I can only guess, but a humming stepper usually has one coil the wrong way round.
Compare cable colors and pin positions with a working stepper.

Hi Olaf

Thanks for your reply. You are right. It turned out to be another cable arrangement than on the Rumba Wiki.
At least for my part.

Cheers
