How to set Steps Per Unit values?
Feb 08, 2016 · Stepper motors usually have 200 or 400 full steps per one rotation of its shaft. One rotation of shaft in degrees is 360°. For motors with 200 steps per revolution this means one step is equal to °. For motors with 400 steps per revolution this means one step is equal to °. In equation below, we will name this parameter M. MicroStepping
