XYZ probe routine location

Since I have a CNC (the Onefinity :), I made my own probe pad. The problem is that it’s thinner than the stock pad sold by Onefinity. The canned XYZ probe routine probes Z just fine but then moves to the X axis and drops the probe too far. My pad is 8.75mm thick and I think the position for the X probe starting point is lower than that by about 1mm.

Where is the probe routine in the software? Is it intended to be user configurable? If not, I’m happy to dig into the python if I can get a pointer to where it might reside.

There are actually a number of things I’d want to change in the BB software, and may engage in the open source project. The other major one is reading the download directory when queried, not just at boot time.
