Digitising Probe

[Muzzer]

That's a pity - it's how these probes are supposed to be clocked. If you think about it, there aren't many other ways to do it sensibly. Have you actually tried it? And how does the manufacturer suggest you do it?

And how does the manufacturer suggest you do it?

Method I've seen mentioned, is centre the spindle over a known bore (a big bearing secured to the bed is ideal - you don't need any fancy gauge ring), then carry out probe centring routines to find out how far off centre the probe is, adjust, and repeat.

And valid point about If relying on software, you need to maintain orientation.
