I was able to get this working. Thanks for the help. I ended up using a macro and modifying G54 Z offset.
My probe is actually a mechanical switch with a touch plate. I use it by placing it on top of the workpiece, then probing with the cutter. This machine has the collet attached to the spindle, so I have to set the Z offset when I change tools. The probe speeds up a tool change considerably. > On Mar 26, 2022, at 7:14 AM, gene heskett <ghesk...@shentel.net> wrote: > > On Saturday, 26 March 2022 02:10:50 EDT Thaddeus Waldner wrote: >> Hi, >> >> I am in the process of installing a probe on my router.
