Where do I define the bed levelling grid max/min parameters for Bi-Linear bed levelling in Marlin 2.0? This used to be in Configuration.h in 1.1.x but its not there now in 2.0

Here is where in Marlin 2.0

The numbers below are for my 3D Printer, this is setup for my Proximity sensor location.

#define AUTO_BED_LEVELING_BILINEAR
#define RESTORE_LEVELING_AFTER_G28

  // Set the number of grid points per dimension.
     #define GRID_MAX_POINTS_X 6
     #define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X
  // Set the boundaries for probing (where the probe can reach).
     #define LEFT_PROBE_BED_POSITION MIN_PROBE_EDGE + 10
     #define RIGHT_PROBE_BED_POSITION (X_BED_SIZE - (MIN_PROBE_EDGE + 10))
     #define FRONT_PROBE_BED_POSITION MIN_PROBE_EDGE + 15
     #define BACK_PROBE_BED_POSITION (Y_BED_SIZE - (MIN_PROBE_EDGE))

In the current/latest version of Marlin 2.0.bugfix available on Github there is no table (as you show above) in Configuration.h to set the boundaries for probing. Its just like this:

#if EITHER(AUTO_BED_LEVELING_LINEAR, AUTO_BED_LEVELING_BILINEAR)

  // Set the number of grid points per dimension.
  #define GRID_MAX_POINTS_X 4
  #define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X

  // Probe along the Y axis, advancing X after each column
  //#define PROBE_Y_FIRST

I see!

Why would they change "Marlin-bugfix-2.0.x.zip I think mine is Beta".
This is why users get so confused. when it changes from Beta to Alpha.

Though it appears that is was moved to Configuration_adv.h will have to update to Alpha to see how to deal with the new changes.

#if PROBE_SELECTED && !IS_KINEMATIC
  //#define MIN_PROBE_EDGE_LEFT MIN_PROBE_EDGE
  //#define MIN_PROBE_EDGE_RIGHT MIN_PROBE_EDGE
  //#define MIN_PROBE_EDGE_FRONT MIN_PROBE_EDGE
  //#define MIN_PROBE_EDGE_BACK MIN_PROBE_EDGE
#endif

dear

u can check in Configuration_adv.h

#if PROBE_SELECTED && !IS_KINEMATIC
//#define MIN_PROBE_EDGE_LEFT MIN_PROBE_EDGE
//#define MIN_PROBE_EDGE_RIGHT MIN_PROBE_EDGE
//#define MIN_PROBE_EDGE_FRONT MIN_PROBE_EDGE
//#define MIN_PROBE_EDGE_BACK MIN_PROBE_EDGE
