meaning of the number in the bilinear leveling grid (just a question not a bug)

[jfpion]

with pronterface and rc8 I got

Bilinear Leveling Grid:
      0     1     2
 0 +0.01 -0.13 -0.25
 1 +0.08 +0.01 -0.01
 2 -0.09 +0.04 +0.20

after the G29 (witch work perfectly on my prusa 2 by the way, thank you again)
but what is the meaning ? is it the diference from the G28 Z0 just before ? in mm ? i can't find the answer in the documentation

thank you

The points represent the height of the probed points in relation to the "zero-point" your G28 found.

Make sure to close the issue if this answers your question.

[jfpion]

I suppose it is in millimeters ?

[FHeilmann]

Yes

[jfpion]

thank you

Does point 0, 0 represent the first point probed? And point 2, 2 the last point probed? I'm trying to figure out what the numbers represent, as well. Which direction is my bed represented with by those numbers... Thanks

@aplocher — 0,0 is the mesh point closest to the smallest XY position in the measured bounds. So, if the bounds specified for G29 were given as L20 F20 R180 B180 then...

X020 Y180     X100 Y180     X180 Y180
   0    2        1    2        2    2


X020 Y100     X100 Y100     X180 Y100
   0    1        1    1        2    1


X020 Y020     X100 Y020     X180 Y020
   0    0        1    0        2    0

Thank you that makes perfect sense and is exactly what I was looking for!
