Revision to Using mesh bed compensation

Jason Znack

Use the command G29 (or G29 S0) to run the probing sequence. All points in the mesh that are reachable by the probe will be probed. When probing is complete, a message will be returned indicating whether or not it was successful. if it was successful, the height map will also be saved on the SD card.
+Multiple heightmaps can be saved with unique names using G29 S3 P"filename.csv". The heightmap can then be loaded at a later time with G29 S1 P"filename.csv". G29 S1 will load the default "heightmap.csv"
+
== Examine the height map ==
* Preheat the printer and establish the Z=0 datum in exactly the same way that you did before you ran bed probing - see [[#Establish a Z=0 datum using the Z probe]]
* Then use command G29 S1 to load the height map from the SD card.

Do not use G29 S1 within config.g, because no Z=0 datum has been established at that point. If you wish to load the height map automatically, here are some options:
