Implement a Z guard using the touch probe #11

We should add a macro that will Z probe a surface and adjust the machine Z limit so that the machine cannot move below that location. This should allow some level of protection from bad tool paths accidentally hitting work holding or fixturing.

It might be possible to implement this using M599 keep out zones.

benagricola commented 6 months ago

Not possible yet as M599 keep-out zones work on machine co-ordinates rather than tool co-ordinates.
