G-code

Widely Used

• G1 E10 - spit 10 mm of filament
• M92 - sets feed rate, such as extruder - M92 E408
• G92 - resets coordinates to given values [1]
• G90 - set absolute positioning
• G91 - set relative positioning
• M106 - 0-255 for fan speed
• Homing - G28 ; home all axes (X, Y, and Z); G28 X Y ; home X and Y axes; G28 Z ; home Z axis only

Status Codes

• M119 - status of endstops (triggered, not triggered)
• M503 - Print the current settings – Not the settings stored in EEPROM.
• M501 Read all parameters from EEPROM. (Or, undo changes.)

Filament

• M404 N2.85 D1.0 - 2.85 mm filament and nozzle Diameter of 1.0 mm

EEPROM

• M501 Read all parameters from EEPROM.
• M503 Print the current settings – note: NOT the settings stored in EEPROM.
• M501 Read all parameters from EEPROM.
• M502 Reset current settings to defaults, as set in Configurations.h
• M851 Z probe offset from Extruder

Notes

• When moving printer in the Cura command line - use G92 without parameters to set all axes to zero
• G1 will always work when coordinates are reset to zero, otherwise if you are alraedy at say E25, G1 E25 will not move the extruder.
