@ -7,7 +7,7 @@ Background
This mesh based method of leveling/compensating can compensate for an non-flat bed. There are various opinions about doing this. It was primarily written to compensate a RigidBot BIG bed (40x30cm) that was somewhat bent.
Currently there is no automatic way to probe the bed like the Auto Bed Leveling feature. This might soon be implemented though, stay tuned.
Currently there is no automatic way to probe the bed like the Auto Bed Leveling feature. So, you can not enable `ENABLE_AUTO_BED_LEVELING` at the same time. This might soon be implemented though, stay tuned.

Issuing a `G29` will return the state of the mesh leveling and report the probed points.
Probing the bed with G-codes

Probing the bed by G-codes follows the sequence much like doing it with the display.
`G29` or `G29 S0` will return the state bed leveling.
`G29` or `G29 S0` will return the state of the bed leveling and report the probed points. Where X=1 Y=1 is the top-left value and X=MESH_NUM_X_POINTS Y=MESH_NUM_Y_POINTS is bottom-right value. X per column and Y per row.
`G29 S1` will initiate the bed leveling, homing and traveling to the first point to probe.

`G29 S2` will store the point and travel to the next point until last point has been probed.
`G29 S3 Xn Yn Zn.nn` will modify a single probed point. This can be used to tweak a badly probed point. Specify probe point where `Xn` and `Yn`, where `n` in `Xn` is between 1 and `MESH_NUM_X_POINTS`. Likewise for `Yn`. `Zn.nn` is the new Z value in that probed point.
