SOLVED M584 won't swap X/Y motor axes

  • Duet 3 6HC board

    FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.01-RC9 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2020-04-21b1

    My X and Y axes are swapped. I don't want to change the wiring. It seems like this should be very doable in firmware.

    The M584 command sets motors to axes, but swapping the motor on X and Y doesn't change the result.

    The result for me is that if I want to move 10mm in the X axis, it moves in the Y axis instead.

    What am I doing wrong?

    It seems like the configuration is taking place. The gantry moved in the Y direction on both of these G0 commands.

  • Oh, I think I get it. I need to reverse direction of one motor.

    Yeah that solved it. The CoreXY kinematics were complicating the understanding of what was going on.

    @TDK said in M584 won't swap X/Y motor axes:


    Update your firmware to 3.1.1 too to avoid getting bitten by bugs.
