Using the feeder in the right way and keeping it clean is important for a good extrusion. Tips on maintaining the feeder
are described below.
FEEDER TENSION
In order to guide the filament properly through the feeder into the bowden tube and print head, it’s important that the
tension on the feeder is set correctly. If the tension is too high, it means that the knurled wheel of the feeder will dig into
the filament, through which it flattens or - even worse - completely gets stuck. This is what we call grinding.
To prevent grinding of the filament it is therefore important to set the tension on the feeder as loose as possible,
meaning that the white insert clip should be completely at the top. You can achieve this by inserting one of the hex
wrenches in the hole on top of the feeder and turning it clockwise.
CLEANING THE FEEDER
After a lot of printing, the knurled wheel in the material feeder can accumulate small plastic particles. You can clean
this by blowing air on the knurled wheel or using a simple brush. It is also recommended to clean the feeder when you
notice grinding of the filament.
