Here is a spreadsheet that will generate G code to use for zeroing all three axis. It is a Macro enabled excel spreadsheet so you will have to enable macros for it to work. That was the only way I could get it to create the g codes. All you have to do is enter the diameter of your bit and the thickness of your touch plate and the spreadsheet will generate the proper g code. I also include some rather crude but hopefully helpful wiring diagram for wiring things up. I hope this helps people who are not too sure about this.
