I am trying to add a 2nd touch down probe to UCCNC. My problem right out of the gate is that as soon as I assign a PIN and Port number to the second probe settings the first probe stops working. I don't even having anything hooked up to the CNC4PC C76/C76 control card. So initially at least this is a UCCNC settings issue.

Probe #1 works just fine with my touch down probe which is a 3-point plate unit for straight down or side hit probing. It has it's own control board with a RJ45 connecto cable from it back to the C78. You can see my settings in the attached image.

But as soon as I add Port 2 / Pin 7 as the 2nd probe address in the I/O settings page of UCCNC I get a PROBE IS BUSY error message when I try to use Probe 1.

Any suggestions on what I've got set wrong?

Thanks,
BH

I would think that the dual probe should work, but I really have never tried it. I checked the manual, but did not find anything that would shed light on the issue. I know that on other programs calling for G31.1 and G31.2... will let you access more than one probe. You may want to play with it.

If you have a C76, I think that the easiest way to do what you are trying to do, is to add a C48 and the Y cable for connecting two probes:

Let me know if this helps.
