G26 - Mesh Validation Pattern

Description

G26 Mesh Validation Pattern is designed to be used in conjunction with mesh-based leveling to test the accuracy of the probed mesh.

The G26 command prints a single-layer pattern over the entire print bed, giving a clear indication of how accurately every mesh point is defined. G26 can be used to determine which areas of the mesh are less-than-perfect and how much to adjust each mesh point.

Notes

Before 1.1.6 requires UBL_G26_MESH_VALIDATION and AUTO_BED_LEVELING_UBL.
Since 1.1.7 requires G26_MESH_VALIDATION and HAS_MESH (AUTO_BED_LEVELING_UBL, MESH_BED_LEVELING, or AUTO_BED_LEVELING_BILINEAR).
