Ok, I did the change to #define AUTO_BED_LEVELING_GRID_POINTS 5

I went to pronterface, ran G28.
when I sent G29 n 2 i got this error message:

Code:
>>> g29 n 2SENDING:G29 N 2
Error:Line Number is not Last Line Number+1, Last Line: 0
[ERROR] Error:Line Number is not Last Line Number+1, Last Line: 0


Resend: 1


I'm searching for information on this error but not getting anything definite - Thanks for any ideas.
