Revision to Using mesh bed compensation

Tony

* If your printer is Cartesian or CoreXY, get the bed as level as you can by mechanical adjustment. Bed compensation increases wear on the Z axis moving parts, so you don't want to be doing more of it than necessary.
* If your printer is a Delta, calibrate it first (see [[Calibrating a delta printer]]). Bed compensation is not a good substitute for accurate calibration.
-* Make sure that your Z probe is correctly configured and working. This includes the trigger height and the X and Y offsets of the probe relative to the nozzle. Refer to the M558 and G31 commands in the GCodes page of the reprap.org wiki at http://reprap.org/wiki/G-code.

* On a Cartesian printer, you can use either mesh levelling (G29) or G30/G32 probing, not both. On a Cartesian printer mesh levelling is recommended but bed probing is still supported for backward compatibility with older firmware configurations.
