This item consists of one Corner Zero finder with set screw and 24" of 26 awg wire. This part is 2" by 2".

How to Use: Attach the wire from the Corner finder to one end of the electrical circuit. The tool in the CNC will be connected to the other end of the circuit. Set the Corner Finder on the corner of the material to be zeroed and either manually or via G-code carefully move the tool to the Top, X edge and Y edge until electrical contact is made.

The parts vary slightly, so please measure the X, Y and Z thicknesses of the touch plate with your calipers and use the measurements as the offsets in your G code/machine.

The center of the large hole is exactly at X0, Y0.
