*
* -----------------
*
* "G" Codes
*
* G0 -> G1
* G1 - Coordinated Movement X Y Z E

* G11 - Retract recover filament according to settings of M208
* G12 - Clean tool
* G20 - Set input units to inches
* G21 - Set input units to millimeters
* G28 - Home one or more axes

* G31 - Dock sled (Z_PROBE_SLED only)
* G32 - Undock sled (Z_PROBE_SLED only)
* G38 - Probe target - similar to G28 except it uses the Z_MIN endstop for all three axes
* G90 - Use Absolute Coordinates
* G91 - Use Relative Coordinates
* G92 - Set current position to coordinates given
*
* "M" Codes
*
* M0 - Unconditional stop - Wait for user to press a button on the LCD (Only if ULTRA_LCD is enabled)
* M1 - Same as M0
* M17 - Enable/Power all stepper motors
