The following table describes some of the anomalies that may occur due to incorrect loading of the filament
together with possible solutions.

Problem

Cause

Resolution

The filament is not fed by the
feeder

assembly.

eye

inspection

the

filament

untouched

without

visible

“notches” from the gear.

Not sufficiently tight, the filament
is not pressed against the gear
correctly.

Increase the tightness of the feeder
assembly

using

the

dedicated

adjustment wheel.

The filament is fed by the feeder
assembly,

but

occasionally

unexpected

“slips”

occur,

moreover  the  material  is  not
extruded.  On  eye  inspection  the
filament can be seen to be heavily
“notched”  or  “consumed”  by  the
gear.

Excessive tightness resulting in
the filament being pressed too
hard against the gear.

Reduce the tightness of the feeder
assembly

using

the

dedicated

adjustment wheel
