CNC Probe - Tried this one?

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.

I have two of these. I got mine from the USA but I think its the same unit. Does what I need, its wired as a probe input via my CS Labs into Mach. I dont have a plugin to use it properly yet, just a lack of time from my side. Not as accurate as a Renishaw but nowhere the same cost either.

I have one spare - happy to sell it for around £75 including local shipping.

Thanks

I've got the deepgroove1 touch probe, although I think it's one of the more expensive ones now, however I can't fault it.

Repeatability is in the sub 0.05mm range, but some/most of that is likely to be lack of repeatability in the machine it's mounted on. I made up a small interface board for mine, as I didn't want to switch the KStep 24V opto directly with it, so the board means the probe is only switching 5V. The board also provides a couple LEDs so I know it's got power, and if the probe is triggered.

I bought two of these type (they're all the same really) from George (komatias) but haven't had time to play with them yet. I also need to make more travel on the Z axis now to use them as they're quite long.
