===== Mesh Bed Levelling on the A5S & A1 =====
If you are using the [[a5s:firmware|community custom firmware]], one of the new features is mesh bed levelling. This is not available on the factory firmware.

=== How to perform Mesh Bed Leveling using the screen ===
  - Select Level Bed then choose Level Bed (not Cancel) in the sub-menu.
  - Wait for Homing XYZ to complete.
  - When Click to Begin appears, press the "enter" button to move to the first point.
  - Use the up/down buttons to adjust Z so that a piece of paper can just pass under the nozzle.
  - Press the "enter" button to save the Z value and move to the next point.
  - Repeat steps 4-5 until completed.
  - Use Control > Store memory to save the mesh to EEPROM, if desired.
  - Dont forget to add "M420 S1" in your start gcode, so that your printer uses the level mesh when printing!

=== Other Methods ===

Mesh bed levelling can also be performed over a USB cable to a computer, using printer control software like [[http://www.pronterface.com/|Pronterface]]. See [[a5:mesh-bed-levelling-routine|this page]] for a guide how to perform manual mesh bed levelling from a computer.
