Would anyone care to share probing macros for a fanuc 18i control, or similar?

Or maybe point to where they can be found?

Thanks!

That's too broad of a question for probing macros. It depends on your probe make/model, machine, machine control, mill/lathe, mill/turn, variables used by machine builder, etc.

Are you adding a probe or looking for more subs on existing? Generally, going back to the builder is the best if you're missing them...

Actually, the probe is an accurate switch that send a on or off signal to CNC controller when the stylus was contacted (trigger) the component. There are two kinds of function that use measured both tool's length and diameter,which is put on the table of machine tool or set up a pull down arm beside spindle head in the lathe, is called tool setting and use measured the parts of features, which is set in spindle head or lathe's turret, is called inspection probe. For Fanuc or Meldas controller, all moving command is used G31 (skip function) when it received the signal from probe trigger. The machine was stopped moving immediately. For example: The parts of inspected program,
