// There are 3 different ways to pick the X and Y locations to probe:
// 1. Basic 3-point probe at left-back, left-front, and right-front corners of a rectangle
// 2. Probe all points of a 2D lattice, defined by a rectangle and ACCURATE_BED_LEVELING_POINTS
// 3. 3-point probe at 3 arbitrary points that don't form a line.
// There are 2 different ways to pick the X and Y locations to probe:
// To enable mode 1:
// - #define ENABLE_AUTO_BED_LEVELING
// - Set the XXXX_PROBE_BED_POSITION values below
// - Don't define AUTO_BED_LEVELING_ANY_POINTS or ACCURATE_BED_LEVELING
// - "grid" mode
// Probe every point in a rectangular grid
// You must specify the rectangle, and the density of sample points
// This mode is preferred because there are more measurements.
// It used to be called ACCURATE_BED_LEVELING but "grid" is more descriptive
// To enable mode 2:
// - #define ENABLE_AUTO_BED_LEVELING
// - Set the XXXX_PROBE_BED_POSITION values below
// - #define ACCURATE_BED_LEVELING
// - Set the ACCURATE_BED_LEVELING_POINTS to your desired density
// - "3-point" mode
// Probe 3 arbitrary points on the bed (that aren't colinear)
// You must specify the X & Y coordinates of all 3 points
// To enable mode 3:
// - #define ENABLE_AUTO_BED_LEVELING
// - #define AUTO_BED_LEVELING_ANY_POINTS
// - Set the ABL_PROBE_PT_XXXX values below
// - Comment out (undefine) ACCURATE_BED_LEVELING since that is incompatible
