Can’t load filament?
If you are having problems loading filament
into one of the extruders, perform the
following steps:
1. Go to the LCD panel and select Utilities
> Filament Options > Unload. This option
heats the extruders.
2. Set the extruder arm to the open position.
3. Make a fresh cut at the end of the
filament. It is important that the filament
have nobends in it. If it does, cut o the
bentsection of filament.
4. Insert the filament into the hole at the top
of the extruder. Keep pushing it in until you
start to see plastic come out of the nozzle.
5. When the filament is successfully
loaded, set the extruder lever arm to the
closed position.
If filament still doesn’t emerge from the
nozzle, remove the filament from the top of
the extruder and check for a bend at the end
of the filament. If the filament is bent, it is
possible that the filament is slipping under
the extruder bearing instead of entering the
extruder heater. Remove the extruder fan
and assembly using the instructions in the
section Disassembling an Extruder. This
will allow you to watch the filament travel
through the extruder and determine where
the filament is getting stuck.
It is also possible that you are unable to load
filament because a broken piece of filament
remains inside of the extruder. Remove
the extruder fan and assembly using the
instructions in the section Disassembling
an Extruder and use a pair of pliers to
remove the broken end of filament.
