Re: [CAD_CAM_EDM_DRO] Re: Tool diameter compensation

Oh, yes there is, but I don't know that it's worth the effort. You'd have
to swap the controllers between the Y &Z plane.
Probably need to do some readjusting too. The machine woul then assume the
Z plane was the Y plane and vice versa. Now, there should be no reason you
couldn't use your cutter comp.
