Mesh Bed Levelling
Mesh bed levelling allows you to level the bed at as many points as you would like to, in a grid. This allows you to get perfect first layer height anywhere on the large bed - and it does not matter if it is warped or not!
Before you can use this feature, you will first need to install the custom firmware. Once you have done that, you are ready to proceed.
DaHai has a good video on how to setup and perform mesh bed levelling on the A5, on his Youtube channel.
Once you have performed the mesh level, and stored it to EEPROM, you now need to tell your slicer to USE this feature. You need to add the gcode “M420 S1” into your start gcode section in your slicer. This needs to go RIGHT AFTER the G28 homing command, in order to enable the mesh correction before printing starts. The G28 command for homing will DISABLE the mesh bed levelling, so it is important that you give this command right after it.
