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.

- | The important thing to remember, is 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. | + | **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! :) |

+ | **Step 1.** | ||
+ | Enter command "G29 S1" into the command line, and press enter. This will start the mesh bed levelling routine. | ||
+ | |||
+ | **Step 2.** | ||
+ | Place a sheet of paper (normal printer paper) under the nozzle. | ||
+ | |||
+ | **Step 3.** | ||
+ | Use the fine-movement jog controls in pronterface to move the nozzle up and down, until the nozzle is just starting to grab at the paper. You should still be able to move the paper around, but there should be a small amount of friction or drag from the nozzle. | ||
+ | |||
+ | **Step 4.** | ||
+ | Enter command "G29 S2" into the command line, and press enter. This will save that height for that point, and nozzle will move to the next point. | ||
+ | |||
+ | **Step 5.** | ||
+ | Repeat steps 3 and 4, until the process is completed. Make sure you enter "G29 S2" after the final point. | ||
