I decided to mount a carriage bolt (adjustable) down near my home position. I just set it around -1 on the X axis. I would like to set it up so I can zero all bits on this bolt. Any one have a custom file written for this type of action so I can just hit C4 with my new bit and have it go to the correct position and zero my Z. Also, some parts will require zeroing from the material top. Can I just run an extra wire and ground to my bolt so I can keep my z-plate in case I need it?
