Measuring a DRV8825's vref


Im trying to hook up a 1.68A stepper motor as part of a 3D printer. I cant seem to find what pins im meant to test the output on. Any help would be appreciated…

Thanks in advance

Also how to measure how many amps its putting out


I recommend watching our stepper motor driver video, which demonstrates how to measure the VREF voltage and set the current limit on the DRV8825.
