Slic3r
A duct may help in guiding the ow correctly, and there are several
designs available online, for a wide variety of printers.
Slowing Down
Slic3r can tell the printer to slow down if the estimated layer time is above
a certain threshold.
Care must be taken as the intended eect could be mitigated by the
nozzle not moving far enough away from the fresh extrusion, a problem
with small, detailed layers. For this reason it is usually recommended to
use a fan where possible.
Configuring
In simple mode Slic3r will attempt to choose the optimal settings for both
fans and speed. Expert mode gives more granular options.
