ZAX can you help me got a question
@elliscrane My guess would be they set the microstepping for the drivers, usually 1/4, 1/8, 1/16 etc.
Most stepper motors have 1.8 degree steps, or 200 per revolution. Microstepping is a way to decreases the step distance and increases resolution, it is common to use 1/16th so you get 3200 steps per revolution. This also makes the motors run smoother but at the cost of maximum speed and torque.
