Hi everyone I've noticed that in the most recent version of marlin there has been some code added to the configuration.h just after 'additional features'. It used to start with the EEPROM features but now has CUSTOM_M_CODE_POINTS 851? It has no comments with it and I can't find anything explaining what it is or how you find the min max z probe range! I've been having some really strange behaviour from my probe since downloading the latest version and this seems to be the only thing I can find that has been added with no comments, I'm assuming the numbers in it must be affecting my bed levelling. If someone could please explain this to me I'd really appreciate it.
