Nozzle Size (mm)
This defines your nozzle size. The slicing engine uses this value combined
with your other settings to determine how quickly to feed filament into
your hot end. The Mini ships with a 0.5mm nozzle.
Retraction Speed (mm/s)
Retraction Speed determines the speed at which your filament is reversed
out of the hot end for travel moves and when changing direction during
printing. We recommend keeping this set to 25mm/s.
Retraction Distance
Retraction Distance determines how much filament is pulled out of your hot
end on travel moves and when changing direction. You will want to adjust
this depending on temperature settings and filament type. Higher thermal
retaining filaments such as PLA behave better with a longer retraction
distance. We have found anywhere from 1mm to 3mm is a good starting
range.
Initial Layer Thickness
This will control how thick your first printed layer height is printed onto
the heated bed. Having a larger initial layer height will help prevent your
part from popping off the plate. Your LulzBot Mini auto leveling system
could be affected if you change this from the standard profiles. Adjust at
your own risk.
Initial Layer Line Width
This will control how wide your first extruded filament path is for the initial
layer. A wider line width will help with bed adhesion. We have found 125%
to be a good starting place. For models with moving printed in place parts,
a smaller initial layer line width is recommended. Your LulzBot Mini auto
