    Mach3 strange sounds when backlash comp is on.

    When I have backlash comp turned on and set up properly everytime an axis changes direction the machine makes a strange cluncking sound. With backlash off the machne runs very quite. Has anyone else came across this strange problem? It is a stepper system on a PM20-PM25(long table and 750watt motor on a PM20) machine.

    Thanks
    Tommy

    Hoss recently posted a video which shows some differences in Mach settings in dealing with backlash comp.

    Perhaps it may shed some light on what's going on with your mill.

    I guess it was resurrected recently, but shot a while ago....
