Marlin/Marlin_main.cpp

  *
  * "G" Codes
  *
- * G0  -> G1
- * G1  - Coordinated Movement X Y Z E
- * G2  - CW ARC
- * G3  - CCW ARC
- * G4  - Dwell S<seconds> or P<milliseconds>
- * G5  - Cubic B-spline with XYZE destination and IJPQ offsets
- * G7  - Coordinated move between UBL mesh points (I & J)
- * G10 - Retract filament according to settings of M207
- * G11 - Retract recover filament according to settings of M208
- * G12 - Clean tool
- * G20 - Set input units to inches
- * G21 - Set input units to millimeters
- * G26 - Mesh Validation Pattern (Requires UBL_G26_MESH_VALIDATION)
- * G27 - Park Nozzle (Requires NOZZLE_PARK_FEATURE)
- * G28 - Home one or more axes
- * G29 - Detailed Z probe, probes the bed at 3 or more points.  Will fail if you haven't homed yet.
- * G30 - Single Z probe, probes bed at X Y location (defaults to current XY location)
- * G31 - Dock sled (Z_PROBE_SLED only)
- * G32 - Undock sled (Z_PROBE_SLED only)
- * G33 - Delta Auto-Calibration (Requires DELTA_AUTO_CALIBRATION)
- * G38 - Probe target - similar to G28 except it uses the Z_MIN_PROBE for all three axes
- * G90 - Use Absolute Coordinates
- * G91 - Use Relative Coordinates
- * G92 - Set current position to coordinates given
