  • Hi all. I broke one motor in the delta. Can I replace it with a motor of 0.9 degrees, if the remaining 1.8? If yes, is it necessary to set a fixed microstep or will it work with interpolation too?

    That should work, although I've never tried it. In the M92 command, you will need to double the steps/mm for the tower that has the 0.9deg motor.

    When using 0.9deg motors on delta printers, you need to use 24V power to get good travel speeds.



  • dc42, Thank you, David. I was waiting for your answer) I have two 0.9 motors from the FlingBear Tornado and I rearranged them on Tevo LM. The third motor is waiting. Now I test their work on the 32 step. Should we expect problems if you enable dynamic interpolation? Will I lose microsteps?



  • @dc42 look above

    On the Duet WiFi/Ethernet, microstep interpolation only works when the microstepping is set to x16. There is no reason to set microstepping greater than x16, especially when using 0.9deg motors.
