Auto bed levelling? am im doing it the wrong way?

// 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

i see on your blog that you connect 2 pin on the Gnd and 5v and 1 pin next to jumper wire it seem different from my setup
