RE: [CAD_CAM_EDM_DRO] Question Re: Work Offsets

Tom,

I think you need to do fixture offsets as those are persistent. It does
not solve my problem as I need to change the zero position
programatically and have it persist, but from the discussions when I
first tried the BDI version of EMC I seem to remember this as being the
"proper" way to handle it.
