I had a problem using my tool height touch off and my probe
My height touch off was active low, a peace of urethane with a peace of aluminum glue to it.
But the probe was active high, to use both I had to go in to ports&pin and change it back and forth, not well
So I come up with this probe (active low)
It can repeat at .0006
Out of round .0009
For me, that good enough.
It can be made (active high) to, the over all length is 5” but I think I can cut that back to 4”
This was just the prototype, just two hours to make it and that’s with a design change in
Mid stream.
