Here is how to do a leveling with a greater matrix: > [@How to do a larger than 3 x 3 matrix level](https://forum.snapmaker.com/t/how-to-do-a-larger-than-3-x-3-matrix-level/5727): > > So here’s my attempt at doing a leveling matrix larger than 3 x 3. Please be advised that this is not for the faint of heart. If you mess up this process you can bury your nozzle into your print surface. I know, I did. I’ll try and tell you how to avoid that. If you aren’t having any trouble with the first layer of printing then this process isn’t for you. I am doing this on an A250, so you may have to change some things for your size Snapmaker. The controller has a version of leveling that the… But honestly I’m not sure how to proceed with the nozzle offsets, but it seems you know the way to go.

However the offset from the print sheet is always way too high usually about 1.5mm above the board. I tried to fix this with a manual Z-Level from the menu but this was pretty hit and miss as I had to do it with the calibration card and getting this consistent is hard enough for one extruder, almost impossible for two extrude… --- _[View the full topic](https://forum.snapmaker.com/t/dual-extruder-bed-leveling-gcodes-missing/40190)._
