Theory
------
The bed is manually probed in a grid maner. During a print the Z axis compensation will be interpolated within each square using a bi-linear method. Because the grid squares can be tilting in different directions a printing move can be split on grid square borders. During fast travel moves one can sometimes notice a de-acceleration on these borders.

Mesh point probing can either be carried out from the display, or by issuing `G29` commands.
The Z-endstop should be set slightly above the bed. An opto endstop is preferable but a switch with a metal arm that allow some press though should also work.

If `MANUAL_BED_LEVELING` has been enabled then will a `Level bed` menu option be available in the `Prepare` menu.
When selecting this option the printer will first do a homing, and then travel to the first probe point. There is will wait. By turning the encoder on the display the hotend can now be lowered until it touches the bed. Using a paper to feel the distance when it gets close. Pressing the encoder/button will store this point and then travel to the next point. Repeating this until all points have been probed.

If the EEPROM has been enable it can be good to issue a `M500` to get these points saved.
