Re: Unified Bed Leveling - border mesh points??

I found this in configuration_adj.h:
// @section leveling

#if ENABLED(MESH_BED_LEVELING) || ENABLED(AUTO_BED_LEVELING_UBL)
// Override the mesh area if the automatic (max) area is too large
//#define MESH_MIN_X MESH_INSET
//#define MESH_MIN_Y MESH_INSET
//#define MESH_MAX_X X_BED_SIZE - (MESH_INSET)
//#define MESH_MAX_Y Y_BED_SIZE - (MESH_INSET)
#endif

This seems like what I need??
I have #define DELTA_PRINTABLE_RADIUS 96.0
In the photo above, the slicer has disc as 190mm, 190/2 = 95. That disc is just about the maximum size I feel comfortable that the bltouch wont collide with a tower to print.

So make the mesh slightly bigger to get editable points for the edges????
#define MESH_MIN_X -5
#define MESH_MIN_Y -5
#define MESH_MAX_X X_BED_SIZE +5
#define MESH_MAX_Y Y_BED_SIZE +5
Good??
