Re: [CAD_CAM_EDM_DRO] Question Re: Work Offsets

Ok, let me put this question another way:

I am generating absolute coordinate G-code (i.e. if I do a "G0X1.0"
followed by a "G0X0.0", I expect to be at x=0).

I am using an edge finder to set my workpiece (0,0,0) point. In this
coordinate frame, z=0 has the tool touching the top of the workpiece (so
all negative Z coordinates are inside the material, and positive Z
coordinates are above it.) In this coordinate frame, the centerline of
the tool is lined up with the lower left corner of the material.

What steps do I need to perform so that when I reach a line in my program
that says "G0 X0.000 Y0.000 Z0.000", the tool moves to the workpiece
(0,0,0) point?
