This is a simple project but one you will find very handy to have when working with a CNC router. This touch off plate uses a simple circuit with an LED light to tell you when the router bit is touching the plate that is placed on the work piece. Then you can set the proper Z-value for that bit. This makes changing bits easy and repeatable!
