Leadshine hybrid servo drive tuning

  • Continuing the topic: https://forum.duet3d.com/topic/12582/mesh-calibration-not-working-or-what-am-i-doing-wrong
    Briefly - the problem with the first layer.

    I think now the main problem is skipping Z steps

    On the Z axis I have a Leadshine hybrid servo drive HBS507

    And all that tested before that was with the setup of the M569 P7

    After the last print, I noticed Hiccups 64

    Next, I made the M569 P7 T2.5: 2.5: 5 - no result

    Then M569 P7 T5: 5: 6 and Hiccups 20, and got better print

    Then M569 P7 T20 and even better print and Hiccups 4
    True, I constantly executed the M122 command during the printing process - it seems that it resets Hiccups

    Where to go next? What should be the timings for my motor?

  • I just think 20ms is too much.

    Can you share what settings you think are normal or use yourself?
