Printing with LW-PLA or other low density foaming filaments requires some individual
printer set up. You should follow the manufacturers guidance. The table below will provide
some ball park figures for printing temperature and flow rate.
For this model we are trying to achieve a single 0.4mm wall, using a low % infill, with flow
rate <60%
The infill print speed should be set to a value ~2x higher than the wall speed.

Retractions are On and set to 0mm as foaming filament doesn’t like to be retracted. Having the setting on
however allows the nozzle to be primed (Retraction Extra Prime Amount) before starting a layer to
prevent under extrusion at layer change.
