Tips: Full-step drive mode of stepper motor
In the full-step operation, the same kind of stepper motor can be equipped with full / half step driver, as well as subdivision driver, which, however, have different operation effects. The stepper motor driver cyclically energizes the two coils of the two-phase stepper motor (set current for the coil) in pulse / direction commands. Each pulse of this type of drive will move the motor by a base step angle of 1.80 degrees (a standard two-phase motor has a total of 200 step angles in a coil).

Recommend this 3-phase stepper motor drive

This stepper driver runs my Nema 34 smoothly on a CNC router. The 6A output provides plenty of torque, and the 32-bit DSP keeps vibration low. Easy to wire and configure. Rock solid performance.
