 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! Mesh bed levelling allows you to level the bed at as many points as you would like to, in a grid.

 **Firstly: This is a very repetitive process. But you need to focus, as if you mess up, you will need to start from the beginning. Make sure you are in a good mood, and are happy to be patient and persevere - the results will be worth it! :) **Firstly: This is a very repetitive process.

-===== How To Perform Mesh Bed Levelling ======+=== FAQ: What is GCode? === 
 +Gcode is just the language for the instructions that the printer follows to perform a print. Cura or your slicer, simply translates the STL file into the GCode that the printer run on. Pronterface allows us a way to send individual GCode commands one by one, and this is the way we can communicate to the printer, and perform procedures like this one.

-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.+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 [[https://jgaurorawiki.com/start-and-end-gcode|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. 
 + 
 +If you want to check the mesh that you have produced, you can use the command "G29 S0" to print a mesh report to the command line history window.

 + 
 +====Mesh Bed Levelling via LCD==== 
 +If you have installed both the [[a5:firmware|custom motherboard firmware]] and the [[a5:lcd-firmware|custom LCD firmware]], then you can perform mesh bed levelling via the LCD screen. Note, that the LCD screen is very sensitive, so be careful to avoid causing double taps!  
 +  - Go the more menu. 
 +  - Press "mesh bed levelling" button. The printer will home, and then automatically move to the first point 
 +  - Use the "mesh up and down" buttons until the desired gap is correct. 
 +  - Press the "next point" button to go the next point.  
 +  - Repeat this until all the points have been levelled.  
 +  - After the last point is completed, when you press the "next point" button, the head will return to the home position. 
 +  - Press the "Save EEPROM" button to save your mesh to the firmware. Otherwise, it will be lost when you restart the printer. 
 +  - Don't forget to add M420 S1 to your [[:start-and-end-gcode|start gcode!]]!
