Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

  Quote  Changes STEPPER functionality to ensure steps cannot be missed by drivers that need a pause between step pulses. Note this limits the maximum pulse rate to 50KHz (100KHz interrupt rate). The code will warn you if you specify a maximum axis speed which when multiplied by the steps/unit exceeds this.


Industrial servo-drives can accept step/pulse & direction as position commands (counters). They then, internally close the loop on a servo-motor & encoder.

Question: Since these drives can handle much higher pulse-rates, do we have the horsepower available to bump-up the 50KHz?

The RP23CNC is claimed to achieve 300KHz
