Re: [CAD_CAM_EDM_DRO] Stepper motors only turning one direction

Hi cold (name?),

I have a driver/PS built up with CN0124 modules. Do you have 5V power
to the modules? You also need a 5v return.

My schematic posted on SherlineCNC site.

The Drivers/PS PDF.

Do you have the 42 page data sheet?

The distance problem is probably scaling. 200 step/rev * 10 * TPI.
