Unknown rows in Configuration.h
I'm traing to tune up mu printer and read a lot in the Firmware settings. When I compare my current Configuration.h with the new ones that I made, I found some differences for wich I can't found any descriptions, nor where from they come:
The first groupe is this:
The second is this:
#define ZHOME_MIN_TEMPERATURE 0
I guess, thous settings are important too, but I'm not sure how they will change the work of the printer. And because I'm affraid to made any changes without knowing what exactly I do, I ask for some help.
Thanks in advance
P.S. My Z probe works, but I'm not sure is it works correctly.
