- Level your preheated bed as well as you can - Insert an SD card, enter the print menu.
- Send `G29 S1`, your nozzle will go to the first calibration position - Enter the special menu by selecting it and pressing the round arrow:
- Don't adjust the bed itself with screws, only use software from here on:
- Use a paper (I recommend using thermopaper like a receipt or baking paper) ![Special Menu][menu]
- Use the onscreen controls or a tool like OctoPrint to lower or raise your nozzle until you feel a light resistance
- If 0.1 mm steps are not enough, you can send specific commands down to 0.02 mm via those three commands: - In this menu, the round arrow is used to execute the command you selected.
- To raise: `G91`, `G1 Z+0.02`, `G90` (one after another, not in one line) - Preheat the bed to 60°C with this entry: (if you usually print with a hotter bed, use the Anycubic menu)
- To lower: `G91`, `G1 Z-0.02`, `G90`
- I also added fine Z axis controls to the special menu, might be easier to use. ![Preheat bed][preheat]
- When done, send `G29 S2` and repeat the process for the next level point. Continue with `G29 S2`every time.
- After finishing the 25 points, the printer will beep and calculate. - Level your preheated bed as well as you can with the four screws.
- After seeing `ok` in the console, send `M500` to save. - Start the mesh leveling:
![Start MMBL][start]
- Your nozzle will now move to the first calibration position.
- Don't adjust the bed itself with screws, only use software from here on!
- Use a paper - I recommend using thermopaper like a receipt or baking paper
- Use the onscreen controls to lower or raise your nozzle until you feel a light resistance: (If you want to send the same command multiple times, select the item again, even though it is still marked red.)
![Z axis controls][control]
- Once finished , move to the next point:
![Next mesh point][next]
- Repeat the last two steps until all 25 points are done.
- Your printer will beep, wait 20 seconds and then save:
![Save to EEPROM][save]
- Reboot your printer.

Note: By default, this firmware probes 25 points. This might take little while, if you don't need an as precise mesh, you can change the grid size by sending `G29 Px` before starting the leveling. E.g., `G29 P3` results in a 3x3 mesh, thus only 9 points.
#### Manual commands for use with OctoPrint etc.:
- `G29 S1` - Start MMBL
- `G29 S2` - Next Mesh point
- Raising Z: `G91`, `G1 Z0.02`, `G90` (one after another, not in one line)
- Lowering Z: `G91`, `G1 Z-0.02`, `G90`
- After seeing `ok` in the console, send `M500` to save.
