M600 - Filament Change

1.1.0 filament Automatically change filament ADVANCED_PAUSE_FEATURE


The M600 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 may be initiated automatically if a filament runout sensor is installed.



The settings for this command can be found in Configuration_adv.h. At this time M600 requires an LCD controller.

Number of beeps to alert user of filament change (default FILAMENT_CHANGE_ALERT_BEEPS)


    Retract before moving to change position (negative, default PAUSE_PARK_RETRACT_LENGTH)


      Load length, longer for bowden (negative)
