Cross reference materials
extrusion temperatures when
purging dissimilar materials. If
the minimum extrusion
temperature for the high
temperature material is higher
than the maximum extrusion
temperature of the low
temperature material then you
will risk burning the low
temperature material and
clogging your extruder. If there is
no overlap in material processing
temperatures, you may require
an intermediary purge material.
Run extruder in manual mode
until purged of previous colour
and fully transitioned to the new
colour. Colour can also be
switched at any time during
regular extrusion.
Run extruder in manual mode
until purged. Plastic may be wet
if you notice necking or bubbles
(or pockets) in extrusion. You
can leave nozzle on for wet to
dry plastic conditions.
