CNC Probe - Tried this one?

[lucan07]

I do that with an upside down 4mm broken mill for nothing.

Hmm, but the work or tool needs to be isolated for the circuit to work no??

[lucan07]

Not on my current MDF bed and on the mill usually in the vice when edge or centre finding vice is easy to isolate when mounting.

[Davek0974]

Ah Ok.

Most of my stuff is clamped to the mill table so no way of isolating it really, would need to be an isolated tip probe.

This would be an isolated tip, pick up the wires from beeper or led switch to connect to mach probing and save 90%

Interesting, thanks, I would have to butcher it though as the body is 20mm - mini-mill max is 12mm

Still, it might serve as a useful donor of parts.

They do a 12mm as someone was posting the other week on here "Boyan" I think i recall, and as Mach inputs are usually 5v even taking battery connections should work, leaving beep and led intact.
