Strange artifacts on X with moons stepper motor 1,8 degree

  • Hello dear duetter's! Iv'e recently upgraded my Ender 3 Pro with a Duet Wifi board. Yesterday i decided i wanted to try some new stepper motors and these "zitz" or whatever you want to call them appeared! the motor is on the X axis and is a moon's 1.8 degree 1A motor. When i print a XYZ cube it seems to be fine. Just when there is movment with both X and Y this appears. thanks!

  • @Bungo First thing I would do is reduce the motor current on the X the recommendation is to run 70-80% of specified currents. you should never run them at there max ratings.

  • I tried with 75% and nothing changed;(

    Loose grub screw? Belt tension different?

    If you swap back to the other motor does it go away?

  • @Phaedrux Hey! no i checked that! havnt tried with old motor but if i scale the benchy up it dissapears ;S
