Shifted Layers; Pillowing - Intamsys FUNMAT PRO User Manual

Shifted Layers

If a printer suddenly shifts the layers it is most likely
because one or more pulleys are not secured
properly to the axis/ axes. Tighten the set screws
that hold the pulleys in place very tightly. Another
issue might be the head being too stiff. Add some
sewing machine oil to solve this issue. Finally,
check that the axis is perfectly aligned. If not, align
the axis to be perfectly square.

Pillowing

Pillowing is bumps on the top surface of the print
that can either be open or closed. When such an
issue occurs, the most important thing to do is to
make sure the cooling fans are at top speed when
the printer is laying down the top layer. Without
proper cooling, thin strands of plastic tend to curl
up and stick up above the surface of the print and
make it harder for the subsequent layers to
properly span over the gap. Another solution is to
print more layers for top and bottom parts,
especially when layer height is very thin.
