Filament Diameter
The lament diameter setting is one of the more important settings. Make
sure that you update this value periodically with your average lament
diameter. While your lament may be referred to as 3mm, it is more
likely going to be near 2.9mm +/- 0.1mm. You will want this to be an
accurate average, as it will allow your printer to correctly calculate how
much lament it is pulling into the hot end. The default value should be
set to 2.85mm.
Filament Flow %
This controls how much lament your printer is extruding in relation to
speed. This setting is mainly used to adjust for lament density variations.
This may need to be adjusted when switching between dierent manufac-
turers or types of lament to adjust for die swell. It is recommended to
make small adjustments between prints for ne tuning.

Nozzle Size (mm)
This denes your nozzle size. The slicing engine uses this value combined
with your other settings to determine how quickly to feed lament into your
hot end. The TAZ ships with a 0.5mm nozzle standard.
Retraction Speed (mm/s)
Retraction Speed determines the speed at which your lament is reversed
out of the hot end for travel moves and when changing direction during
printing. We recommend keeping this set to less than 25mm/s to help
protect the gears.
Retraction Distance
Retraction Distance determines how much lament 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 lament type. Higher thermal
