How do I set more calibration points for Auto Bed Levelling?
Hi all,
I recently installed my 8x12 upgrade for my i3v and I would like to have ABL calibrate the entire bed instead of just the 9 points for 8x8 sized bed, how would I go about this?
Thanks.

Things have changed based on the version of the firmware you are running. But the first step in all cases is to edit your Configuration.h file to set the
#define AUTO_BED_LEVELING_GRID_POINTS 3
higher. Maybe 5?

Assuming marlin firmware, find this section of configuration.h and change the "170" for y to something more appropriate for your 12" bed, e.g. "270".
Code://===========================================================================//============================= Bed Auto Leveling =========================== //=========================================================================== . . . #define AUTO_BED_LEVELING_GRID #ifdef AUTO_BED_LEVELING_GRID #define LEFT_PROBE_BED_POSITION 15 #define RIGHT_PROBE_BED_POSITION 170 #define FRONT_PROBE_BED_POSITION 20 #define BACK_PROBE_BED_POSITION 170

Oh! Yes, it will do a n x n grid. We will have to make a small change if you want more points in one direction than the other.
