Microstepping is a technique to control stepper motors, usually used to gain higher resolution or smoother motion at low speeds. What is Stepper Motors? Stepper motors are open-loop, cheap, user-friendly, and robust motors. They offer numerous advantages over other electric motors: They have high torque at low speeds and stall mode. Their speed is easy to control via modulation of pulse widths (PWM). They have pretty good accuracy. They have a great response to start/stop. When precise and reliable positioning is needed at a low cost, then stepper motors are the obvious choice. What is Microstepping? Consider decreasing torque while micro-stepping a stepper motor for precision. Microstepping is achieved by dividing full steps into smaller steps and this is the reason for the smoothness of motors rotation at low speeds. For example, if you divide a 1.8-degree step 256 times, it will provide a step angle of (1.8/256)=0.0007 degrees or 51,200 m...
