To get the most out of my little SparkFun steppers, I need all the torque I can get. I hadn’t realized that when I first setup my control board. The micro steps can get you extra precision, but as this data shows the cost in torque can be quite high. For example, if I used 8x microsteps on my motors that are normally 200 pulses per revolution, they would jump to 1600 pulses per revolution. ![]() If you needed greater precision than that, you can use micro-steps to send pulses that move the motor a fraction of a step at a time. In my case, the steppers I use take 200 steps per revolution. Steppers are fed pulses from the controller board, where each pulse moves the motor a fixed increment. ![]() ![]() micro steps allow you to get greater precision from your stepper. First, I discovered a bit of useful data regarding stepper motor torque and micro-stepping. I’ve done a bit more tuning on the CNC machine, and it’s running better than ever.
