Marlin 2 Bilinear Auto Bed Leveling (no replies)

Hi Guys.

I'm strugling with the bilinear Bed Leveling on my DIY Printer.

So in Marlin it says:

 * - AUTO_BED_LEVELING_BILINEAR
 *   Probe several points in a grid.
 *   You specify the rectangle and the density of sample points.
 *   The result is a mesh, best for large or uneven beds.

Probe several points in a grid.
is obviously adjusted by these 2 parameters:
#define GRID_MAX_POINTS_X 4
#define GRID_MAX_POINTS_Y 3

but where do I specify the rectangle and the density of sample points? I remember in v1 there were the parameters LEFT_PROBE_BED_POSITION, RIGHT_PROBE_BED_POSITION, FRONT_PROBE_BED_POSITION, BACK_PROBE_BED_POSITION. But I cant find these in v2. I've also setted the NOZZLE_TO_PROBE_OFFSET, which is correct in my opinion, but the printer always tries to probe outside the bed the last 4 points.

#define NOZZLE_TO_PROBE_OFFSET { 16, 33, 1 }

When I'm in front of the Printer the Z-Probe is behind and left to the nozzle so the values are positive (?).


Hope someone can help

best regards
