2.8. ADVANCED TAB OPTIONS
retaining laments 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 rst printed layer height is printed onto
the heated bed. A larger initial layer height is more forgiving and will help
rst layer adhesion. All of our standard proles have a 0.425mm initial
layer height. This eliminates the need for adjustments when switching
between laments. Your LulzBot TAZ automatic bed leveling system could
be aected if you change this from the standard proles. Adjust at your
own risk.
Initial Layer Line Width
This will control how wide your rst extruded lament 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
TAZ automatic bed leveling system could be aected if you change this
from the standard proles. Adjust at your own risk.
Cut Off Object Bottom (mm)
This setting is used to help print models that were not specically designed
for FFF printing. In particular, it is for models that do not have a at
surface to adhere to the plate. It will sink your object Xmm into the build
plate, creating a nice at surface to begin your print. You can also use this
option to remove the lower portion of your model, or if carefully measured,
cut your part in half for printing object as two halves.
