#  SET_RETRACTION [RETRACT_LENGTH=<mm>] [RETRACT_SPEED=<mm/s>] [UNRETRACT_EXTRA_LENGTH=<mm>] [UNRETRACT_SPEED=<mm/s>]
#  SET_RETRACTION is commonly set as part of slicer per-filament configuration, as different filaments require different
#  parameter settings.
#  GET_RETRACTION Queries the current parameters used by firmware retraction and displays them on 
[firmware_retraction]
#   The length of filament (in mm) to retract when G10 is activated,
#   and to unretract when G11 is activated
retract_length: 0.75
#   The length (in mm) of *additional* filament to add when
#   unretracting.
unretract_extra_length: 0
retract_speed: 70
unretract_speed: 40
