Yeah I seen those posts. How accurate is that though and is there risk to damaging something since there is no "spring" area? Is there any advantage to using the actual tool setter vs the copper clad pcb?
I use a circle of PCB material, mounted by its edge. So, when Mach's probing routine loses its mind (which it sometimes does), and tries to drive the tool through the PCB, the PCB just breaks, and I put in a new piece.
If you use tool holders with some kind of a reasonable reference surface (i.e. - CAT, ISO, etc.), you can just use a simple height gauge.
