G26 - Mesh Validation Pattern

1.1.0 calibration Test the mesh and adjust. G26_MESH_VALIDATION

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 G26 requires AUTO_BED_LEVELING_UBL.

Since 1.1.7 G26 also works with MESH_BED_LEVELING and AUTO_BED_LEVELING_BILINEAR.

Usage

G26 [B<temp>] [C<bool>] [D] [F<linear>] [H<linear>] [I<index>] [K<bool>] [L<linear>] [O<linear>] [P<linear>] [Q<float>] [R<int>] [S<float>] [U<linear>] [X<linear>] [Y<linear>]

Parameters

`[B<temp>]`	Bed temperature (otherwise 60°C) to use for the test print.
`[C<bool>]`	Continue with the closest point (otherwise, don’t)
`[D]`	Disable leveling compensation (otherwise, enable)
`[F<linear>]`	Filament diameter (otherwise 1.75mm)
`[H<linear>]`	Hot end temperature (otherwise 205°C) to use for the test print.
`[I<index>]` 2.0.6	Material preset to use for the test print. Overrides `S`.
`[K<bool>]`	Keep heaters on when done
`[L<linear>]`	Layer height to use for the test
`[O<linear>]`	Ooze amount (otherwise 0.3mm). Emitted at the start of the test.
`[P<linear>]`	Prime Length
`[Q<float>]`	Retraction multiplier. `G26` retract and recover are 1.0mm and 1.2mm respectively. Both retract and recover are multiplied by this value.
`[R<int>]`	Number of `G26` Repetitions (otherwise 999)
`[S<float>]`	Nozzle size (otherwise 0.4mm)
`[U<linear>]`	Random deviation. (`U` with no value, 50).
`[X<linear>]`	X position (otherwise, current X position)
`[Y<linear>]`	Y position (otherwise, current Y position)
