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`](/docs/gcode/G000-G001.html) and [`G1`](/docs/gcode/G000-G001.html) 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.
