Sorry, I have sold my h7 development board before, there is no way to test, I have tested the f401, the stable output is 300khz, the f446 is 400khz

Hi, I can test for you. How are you comparing, just a single axis move, or while running a more typical job? Cheers..

Thank you so much!! Only one axis movement

Will get to 700khz stable output on a single axis move, is glitchy by 800khz..

hi, dresco, I haven't tried servo motors, I heard that servo motors need high pulse output control?
