4. Loading or Changing Filament
1. The Nozzle must be hot to add, remove
or change filament so preheat the nozzle
before starting. Hang the filament spool
on the holder so it feeds over the top of
the spool towards the extruder..
To allow the filament to feed smoothly
cut an angle on the end of the filament
(as shown above) to help it enter the
extruder.
2. Press the lever on the extruder to separate the toothed gear and the idler.
Insert the filament into the hole in the lever, between the gear and idler and
into the hole on the other side. Keeping the lever pressed push the filament
through the Bowden tube and into the hot end and nozzle. As long as the
Nozzle is hot enough the filament should start to come out of the nozzle and
the filament is successfully loaded.
To Change Filament:
1. If there is a filament loaded, heat up the nozzle then gently pull the filament out
of the nozzle and extruder with the lever depressed.
2. Cut an angle on the end of the new filament and feed the new filament into the
extruder.
3. Once loaded extrude filament until all traces of the previous filament have been
expelled.
