8.3 Lacking Extrusion.
It is a low extrusion because the filament contribution is not enough, it is noticeable that
the perimeters did not join properly and/or material shortages appear in the filling; the
reasons for that are:
Incorrect filament diameter configuration: The
3DLimitless ILC printer has an Extruder Assembly for a
1.75 mm filament diameter, for this reason you need
to make sure that this is the value in the software and
each of the filament profiles that you have created. We
recommend measuring the filament at various points
to get an average diameter since filament
manufactures have several tolerances.
Increase Extrusion value: The problem could continue even thou the filament
diameter is properly adjusted. To resolve this, as mentioned previously, you can
change the Extrusion value while the printing is going on or when you are setting
the different filament profiles. Modifying the parameters will depend on which
software you are using and if you are printing manually (with dial and LCD) or
remote printing on the manual control tab of the software.
8.4 Over Extrusion.
It is the opposite of the previous section and it means
that too much material is deposited mainly on the
upper surface. In this case it will be done in the same
way but in reverse. You will modify the extrusion
coefficient or FLOW by decreasing the extrusion
multiplier value. The way of doing so it will be
different depending on the software you use. Slick3R
will be like a 0.9 equivalent t 90% which is a 10% less
of extruder. CuraEngine will use percentages, i.e. 80%, 90%, etc.
8.5 Holes on the top part of the pieces.
If you can see holes on the top layers of the object while the rest are correct, the
probable causes are:
Fewer upper layers: As you previously saw, some of the
printing parameters to configure before printing are the
number of upper and lower layers. If the value is too low
the problem will occur. We recommend you configure at
least 3 top layers.
