The BLTouch device seems like a good idea. Did I read that it's supported in Marlin 1.1? There are PAGES of old comments about installing Marlin 1.1. It seems like I read that installation was a breeze IF you got Configuration.h right. Well, it doesn't look like that's gonna be easy. Is there some bottom line final configuration of Marlin 1.1 (or 2) for the R1+?
