    I have a simple brass block with an acrylic piece bonded to it to insulate it from the workpiece. The acrylic and brass were trimmed in the lathe and then the faces of the acrylic and brass were turned parallel. the brass has a 4mm hole in the side for a banana plug to connect to the touch probe input. Mike up the block and that is the tool height offset for Mach3. The BOB has a 10k res to 5v to keep the probe input high until the tool grounds it. A simple macro in Mach3 and I have a tool height setter that is one of my cheapest and most useful accessories.
