--gcode-arcs Use G2/G3 commands for native arcs (experimental, not supported
by all firmwares)
--g0 Use G0 commands for retraction (experimenta, not supported by all
firmwares)
Filament options:
--filament-diameter Diameter in mm of your raw filament (default: 3)
--filament-packing-density
Ratio of the extruded volume over volume pushed
into the extruder (default: 1)
--temperature Extrusion temperature (default: 200)
--extrusion-multiplier
Change this to alter the amount of plastic extruded. There should be
very little need to change this value, which is only useful to
compensate for filament packing (default: 1)
--temperature Extrusion temperature, set 0 to disable (default: 200)
Speed options:
--print-feed-rate Speed of print moves in mm/sec (default: 60)
--travel-feed-rate Speed of non-print moves in mm/sec (default: 130)
--perimeter-feed-rate
Speed of print moves for perimeters in mm/sec (default: 60)
--bridge-feed-rate Speed of bridge print moves in mm/sec (default: 60)

Factor to increase/decrease speeds on bottom
layer by (default: 0.3)
