CNC TOUCH PLATE NOT STOPPING HOW TO
You'll have to look at the manual for your BOB and find out what type of inputs it has then you'll know how to wire it. A better way to zero our tool changes would be the use of a touch plate (conductive plate) to automatically feel our tolerances and zero our machine for us. While this works OK in a pinch, it is very inefficient and not really accurate. That means the inputs are pulled to DC Common with a resistor and you need to connect the boards +V to the pin and activate the input. A common method of zeroing a CNC machines Z axis using Mach3 is done by using the paper friction test. Jogg your touch tool to within 1 inch of the plate and then press 'Touch X - Left'. Enter the Tool Diameter (or Tool number). Some BOBs are active HI, and the CNC4PC boards typically are this way. So - if your are going to touch left, on a plate of the outside of the workpiece at position 0, then the plate thickness should be 0 (it does not affect the position of the touch) and Touch Location should be 0. When you connect DC Common to the pin you pull the pin LOW and activate the input.

CNC TOUCH PLATE NOT STOPPING REGISTRATION
Most input pins are pulled HI, on the circuit board they have a resistor that is connected between the pin and the +V of the board. The page features tutorials and samples to help with your Shark CNC Control Panel Software Registration process. What you need to do in a general sense is complete a circuit between the DC Common and the input pin. By that I mean that DC Common is not the same thing as AC (earth)ground.
