G-codes:
• G0 & G1 ; Move
  see: go to: gCode Details page ...
• G2 & G3 ; Arc move.
• G4 ; Pause the machine for a period of time.
  Parameters: Pnnn ; time to wait, in milliseconds
  Snnn ; time to wait, in seconds
  Example: G4 S2 ; waits for 2 seconds.
• G10 ; Retract
• G11 ; Retract recover
• G21 ; set units to mm
• G28 ; Home axis
  G28 W ; Home x, y and z axes.
  G28 ; Home x, y and z axes and then runs mesh bed leveling (G80)
• G30 ; Single Z Probe
• G76 ; Induction probe temperature calibration.
  Induction probe (PINDA) detection distance increases with temperature. This leads to need of adjusting live adjust Z values often, especially when printing with different materials. Main contributor to PINDA temperature shift is heat received from heatbed.
  G76 runs temperature calibration, which consist of preheating PINDA probe near the heatbed surface for different heatbed temperatures and measuring how its detection distance changes. Measured detection distance shifts are saved to EEPROM.
  When new print is started and using temperature calibration is turned on in Calibration -> Temp. calibration menu, PINDA probe is preheated for two minutes near the heatbed again to achieve defined temperature. Then mesh bed leveling is run and Z axis shift counted from temperature calibration data is applied. Then live adjust Z is applied.
• G80 ; Mesh bed leveling
• G81 ; Print mesh bed leveling status and bed profile if activated
• G86 Prusa3D specific
  Disable babystep correction after home. This G-code will be performed at the start of a calibration script.

  Enable babystep correction after home. This G-code will be performed at the end of a calibration script.
• G90 ; All coordinates from now on are absolute relative to the origin of the machine.
• G91 ; All coordinates from now on are relative to the last position.
• G92 ; Set position to coordinates given without physical movement.
• G98 ; Activate farm mode
• G99 ; Deactivate farm mode

  ??? M73 Q0 ; sets the percentage of the total time printed in the stealth mode
  ??? M73 R0 ; sets the total time remaining in normal mode
  ??? M73 S0 ; sets the total time remaining in stealth mode

• M84 Turn off steppers.
• M85 ... Set inactivity shutdown timer.
• M92 ... Set axis steps per unit.
• M104 ... Sets target temperature for nozzle. Example: M104 S210 Sets nozzle target temperature to 210 C.
• M105 ... Returns current temperatures.
• M106 ... Turn on printer fan.

• M601 ... Long pause
  Suitable for pausing sd card print. Long pause print procedure contains seting nozzle target temperature to zero, moving extruder to pause print position and turning off print fan. When nozzle cools down nozzle fan is also turned off and printer remains silent during pause. Heatbed remains heated during pause print to maintain good attachement between printed object and heatbed. In pause position heatbed with printed object is moved foward to make printed object accessible.
• M602 ... Resume SD card print from long pause. Previous print settings (fan speed and feemultiply, nozzle target temperature) are restored. Time when the printer is paused is not counted to print time statistics.
