I’m using RC7 from this site. The lines you speak of are in the configuration.h file as well. I also noticed the ability to use Z_Min for the probe.
Can you post what your probe info looks like in the file ?
Can I use RC8 from this site or not ?
Btw, I connected my z-min lines to the touch plate and router bit, did a z home (G28 Z) and that works. FYI.
