Frequently Asked Questions
What is microstepping and how does it work?
Microstepping divides each full step into smaller increments, providing smoother motion and higher resolution. The KF8020 supports up to 1/16 microstepping, dividing a 200-step motor into 3200 microsteps per revolution. This reduces vibration and improves positioning accuracy.
Use higher microstepping for smoother motion requirements.
