probing on all metal machine

[routercnc]

Thanks Washout and Jazz, some good suggestions there.

Copper faced PCB board seems like the best solution all round - I don't want to keep changing the bit for a probe etc.

Thanks

Just starting to machine aluminium on my omio cnc and coming across the same problem.

How did you end up solving this routercnc?

I've seen some cheap probes on ebay and amazon but they look all metal so I'm guessing even with a probe it doesnt solve the problem.
