    Mach3 homing slave axis not squaring up

    Good day gentle people.

    I am building a new plasma cnc table to replace my old table.

    A quick overview of the build
    NVEM network controller
    Closed loop stepper motors Hbs86h driver
    Limit switch for all axis

    A Axis is slaved to Y axis

    Machine moves well and is calibrated.

    Here is my problem
    With homing with master limit turned OFF in general config.
    When I reference all home
    The y axis moves to limit switch stops and A Axis does not square up. The system appears to hang. If I activate the A Axis limit manually. It goes green in diagnostic page.
    It appears that once the y axis has hit the limit switch. It is waiting for
    The A limit switch
    But A Axis does not move.
    X Axis does not home.

    If I turn on home with master in general config.
    The homing works fine for all axis.
    But no squaring up.

    I have set the soft limits page.
    On the soft limits page. A and Y axis are set the same.

    I would expect that of this was wrong. They would drive in opposite direction when homed.

    I have looked on many forums and tried multiple settings.
    But can't seem to get this working


    Any suggestions appreciated.

    You can try modifying the homing macro to use RefCombination to home the slaved axis.

    If that doesn't work, then there's a good chance you motion controller does not support slaved homing.
