    Default Moving origin mystery

    Does anyone know if there are any setting in Mach that shifts the origin while cutting? I set the origin off a bolt. Then screw the stock down on the bolt. Then cut a 60mm diameter disk from the stock. The disk then has excessive runout meaning the disk was cut to the right of the origin. Odd thing is that it’s perfectly round.
    I haven’t completely ruled out mechanical movement somewhere but I thought I’d get some feedback.

    FYI I checked everything including cam’ing it two different ways and got same result.
    After carefully using the touch probing feature in Mach to determine what moved where, I’m convinced it’s deflection on the Z axis column.
    I’m seeing nothing that the slides, drives and Mach4 are doing wrong.
