command moves the nozzle to the location corresponding to a specific coordinate in the bed leveling mesh. It operates similarly to the
commands except that the provided coordinates are a mesh row and column instead of an absolute or relative position on the bed.
command will determine the bed position that corresponds to the provided mesh row and column and move the nozzle to that position.
G42 [F<rate>] [I<pos>] [J<pos>]
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.
The column of the mesh coordinate
The row of the mesh coordinate
Move to various points on a 9x9 mesh
