Arduino grbl easel z probe not signalling

I have Arduino uno grbl 0.9j and easel 0.4.0. I have my own firmware settings. $10 keeps reverting to $10 = 115 from my setting of $10 = 3 when I go through “Z probe configuration”. My cnc system works in easel and probes with UGS. Hardware is Arduino 5v to plate and return to Arduino ground. It is an “other” in “edit your machine” window. In the dropdown “machine” > “edit your machine” > “configure z probe” > “confirm” > get green “attached” but cannot go further (z probing works in UGS so hardware good). In “carve” I cannot get past “Plug the lead into the carriage”. Suggestions for why no signal and is “carriage” a leftover from x-carve setup and how do I workaround?

After probing attempt, works with UGS.

• $0=10 (step pulse, usec)

I had a similar issue that I finally resolved today by flashing the grbl to the latest Inventables version. Once I did that, and went through setup, the z probe works fine in Easel.

Thanks StevenDeweese. I gather there is an inventables version of grbl that can be flashed to Arduino uno, i did not know that. I am using the github version and it works awesome. My machine is a custom made designed by myself and works very well with github grbl. Have you got a link as i cannot find that of which you speak. Thanks for the reply mate, Jason.

Thanks StevenDeweese
I go help from the crew at inventables a while back and they offered me the same website so thankyou as well, your help and time is greatly appreciated. At the moment I am working on drilling some angle parts for my machine and so will not be reflashing my uno until I need to use the probe, but all looks straight forward at the moment.
