The [`M600`](/docs/gcode/M600.html) command initiates the filament change procedure. The basic procedure will move the print head away from the print, eject the filament, wait for new filament to be inserted and the user to confirm, load and prime the filament, and continue with the print. [`M600`](/docs/gcode/M600.html) may be initiated automatically if a filament runout sensor is installed.
