Cleaning Nozzle
Needle Cleaning
If residue is clogging the interior of the nozzle, a
thin, flexible needle can break up the blockage
and allow filament to pass freely. An acupuncture
needle or guitar high E-string are ideal tools for
this process.
Tools Needed
Qty
"E-String" or Acupuncture Needle ..................... 1
To clean nozzle interior:
1. Preheat nozzle (refer to Preheating on
Page 26).
2. Insert needle or guitar string into end of noz-
zle (see
Figure 47). Move it around gently to
break up particles and trapped debris.
Note: Material will not be removed by the
needle or guitar string, but it will be loosened
so it can freely flow out during extrusion.
3. Extrude filament to clean nozzle of broken
debris. For instructions on manually extrud-
ing filament, refer to
Moving Axes on Page
30.
Note: Extrude filament incrementally until it is
clean when it leaves nozzle.

A clogged nozzle often leads to major printing
issues. Regularly performing brush and needle
cleaning will help keep the Model G0923 printing
smoothly for many hours of work.
Performing a "cold pull" when changing filaments
helps remove old filament from the interior of the
nozzle. This process uses partially cooled molten
filament to pick up and remove burned filament
from the inside of the nozzle. A cold pull is espe-
cially useful when switching from a dark filament
to a lighter one. If significant buildup occurs inside
the print head, it may be necessary to fully dis-
mantle and clean it.
Nozzle
Brush Cleaning
If the exterior of the nozzle has substantial fila-
ment buildup, it can interfere with filament extru-
sion. A soft wire brush is used to clear away
accumulated debris.
Tools Needed
Qty
Brass Wire Brush .............................................. 1
IMPORTANT: Only use a brass wire brush. Using
a steel wire brush or equivalent may result in dam-
age to the nozzle.
To clean nozzle exterior:
1. Use brass wire brush to remove residue from
nozzle (see
Figure 46).
