Microstepping is a motion control method that can achieve very smooth cuts while still using stepper motor technology. The greatest advantages of microstepping include solving noise and resonance problems and increasing step accuracy and tool positioning resolution. As a result, microstepping can even help minimize tool marks on the finished part.
Microstepping uses special drives in conjunction with standard stepper motors to produce these results. These drives are able to move the magnetic pulses of a stepper motor more smoothly than in full or half stepping drive modes. With the FlashCut CNC microstepping technology, the number of steps per motor revolution (typically 200 or 400 for full/half stepping drives) can be increased to 1000, 2000, and even 12,800 steps per revolution.
