Re: [CAD_CAM_EDM_DRO] Finding Z zero for CNC

You can use a piece of paper between the tool and the part. Move the paper
back and forth while lowering the tool. When the tool grabs the paper you
will be about .002" above the work. It takes a little practice but you will
be able to get predictable results. Measure your paper most I use is .003"
thick.
