Update G000-G001.md

Adding example of single axis homing with S1 option. I had issues with re homing machine between layers with G28. Was able to find older examples using S1 option within G1 (duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_X_and_Y). But did not find any examples of using S1 in your documentation or examples of the canned cycles G28 references or their location within firmware.

In Marlin the S parameter is not used this way because Marlin doesn't have "homing mode" for axes. All homing in Marlin is done through G28, and probes use G29 and G30.

In Marlin, the S parameter in G1 is used for setting laser power when the LASER_FEATURE is enabled.

You are wrong and trying to argue with main project maintainer, who have better comprehension of this code than anyone else. Gcode is barely a standard, each firmware have different flavour. RRF or any other docs are absolutely irrelevant to Malrin.
