;==========================;
; List of relevant G-codes ;
;==========================;
; M92: Set axis_steps_per_unit
;   e.g. M92 X87.489 Y87.489 Z87.489 E420:420
; M204: Set default acceleration
; M206: Offset axes
;
; G90: Set to Absolute Positioning (default)
; G91: Set to Relative Positioning
; G92: Set Position, "only support A axis reset." - in other machines, this can set new absolute origin
; M82: Set extruder to absolute mode (default)
; M83: Set extruder to relative mode
;
; M190: Wait for bed temperature to reach target temp
; M109: Set Extruder Temperature and Wait, Example M109 S215
;
; G0: linear Move  - this is rapid linear move on other systems, G1 is normal speed linear move for them
;   e.g. G0 X000 Y000 Z000 E000 F000
;   F is feed rate, E is extruder
;   Traditionally, S is used for "power", which may be laser power or spindle speed. N/A here.
; G4: Dwell (ms)
;   e.g. G4 P1000
; G28: Move to Origin (Home)
;   e.g. G28
;   e.g. G28 X Y
;
; M0: Stop or Unconditional stop
; M1: Sleep or Conditional stop
; M2: Program End
; M73: Set build percentage
;   e.g. M73 P100
;
; M80: ATX Power On
; M81: ATX Power Off
;
;
; M140: Set Bed Temperature (Fast) - does not wait!
;   e.g. M140 S65 R40   (set to 65°C, wait until 40°C)
; M104: Set Extruder Temperature
