 +=== Fade ===
 +
 +In the above example observe we have enabled bed mesh fade. This trims the amount of compensation the bed mesh is applying over a height range. Here the fade starts at Z=4mm and has been completely tapered off and eliminated by Z=12mm.

 +==== Full Bed Meshes ====
  
 Full bed meshes aren't useful for production printing because they are stale almost immediately, yet they are useful to evaluate the shape of the bed. Having a large probe matrix, such as the Elegoo "Professional" size bed mesh, isn't going to tell us significantly more about the overall bed shape than a 6x6 or 9x9 mesh in less time. We'll want to be using Adaptive Bed Meshes run at print time for production prints and they'll have a denser mesh for just the object size. Full bed meshes aren't useful for production printing because they are stale almost immediately, yet they are useful to evaluate the shape of the bed.

-Note: the G29 gocode is a marlin gcode and not an actual gcode in [[Klipper]], it's implemented as a [[macro]]. Klipper instead implements the ''BED_MESH_CALIBRATE'' command. As such consider using G29 instead of the Klipper command as unreliable and unpredictable as its behavior may change. +==== G29 ====

 +Note: the G29 gocode is a marlin gcode and not an actual gcode in [[Klipper]], and in Elegoo's distribution of [[printer.cfg]] it may, or may not otherwise, be implemented as a [[macros]]. Klipper instead natively implements the ''BED_MESH_CALIBRATE'' command which features a richer set of parameters and can accomodate [[adaptive_bed_mesh]]. As such consider that using G29 instead of the Klipper command is unreliable and unpredictable as its behavior may change. There's no reason not to use the Klipper correct ''BED_MESH_CALIBRATE''.
