This is the Amazon link to the board I purchased.

I took apart my old xyz da Vinci to try and turn it into a cnc just as a fun project since I got a new 3d printer. I found the data sheet for the stepper motors here

When trying to jog the motors using the control board it seems to move them much more than the intended value. I measured with calipers that what the board said was 1mm was actually 9. The board uses the A4988 drivers which I thought would work with the motors since they seem to be nema 17.

Is this a simple software fix or is this board not going to work at all for this project. Thank you in advance
