    rznc-0501 4th (c) lathe axis

    hi, i have this control board running(picture attached), i tried to wire another stepper to c axis and give it some gcode with 4th axis generated with rhinocam.

    now the new stepper not act like a 4th axis but move together with y axis, so i assume they made that slot for machines which need double y axis motors. but thinking maybe it's from firmware or maybe it's gcode.

    so wanted to ask, if i upgrade firmware is it possible to use that c axis as 4th axis?

    if not, a 3 axis lathe still will be useful for me, what is the best way to use x, z and lathe axis and easily switch back to x, y, z axis?

    gcode is here also if you think it's faulty, it's just for simple cylinder:

    Re: rznc-0501 4th (c) lathe axis

    0501 support 3 axis 3linkage , then suggest you take X axis as rotary ,
    Next time ,suggest you choose DSP A18 ,it support 4 axis 4 linkage ,process cylinder wood or square wood.
