Error: M350: Driver 20 does not support x8 microstepping

  • I have been going nuts trying to get my quad Z motors configured right. I thought I had everything figured out but now I am getting the error:
    Error: M350: Driver 20 does not support x8 microstepping

    The extruder was moved to my toolboard at 20.0 and I did not specify interpolation but it gives me the error as if I did.

    See my config below. Can someone tell me what I need to change?

    Which firmware versions are you using, both on the main board and the tool board? Current is 3.01-RC12 on main board and 3.01-RC11 on tool board.

  • @dc42 rc11 on main and tool board

  • @jdumoulin
    The extruder will not move even if I take interpolation out for the other drives.

  • @jdumoulin said in Error: M350: Driver 20 does not support x8 microstepping:


    Scratch all that. I finally found the typo. Im sorry to have wasted your time on this. I checked this thing over and over.
    Extruder was listed as E0.20 instead of E20.0
