G42 - Move to mesh coordinate

1.1.2 calibration Move to a specific point in the leveling mesh HAS_MESH

The G42 command moves the nozzle to the location corresponding to a specific coordinate in the bed leveling mesh. It operates similarly to the G0 and G1 commands except that the provided coordinates are a mesh row and column instead of an absolute or relative position on the bed.

The G42 command will determine the bed position that corresponds to the provided mesh row and column and move the nozzle to that position.


Usage

G42 [F<rate>] [I<pos>] [J<pos>]

Argument Description
[F<rate>]

The maximum movement rate of the move between the start and end point. The feedrate set here applies to subsequent moves that omit this parameter.

[I<pos>]

The column of the mesh coordinate

[J<pos>]

The row of the mesh coordinate
