FILAMENT NOT LOADING
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.
[Fig 1.2]
3. Make a fresh cut at the end of the
filament. It is important that the filament
have no bends in it. If there are bends, cut
off the bent section 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.
You might have to apply some pressure.
5. When the filament is successfully loaded, set
the extruder lever arm to the closed position.
If filament doesn’t emerge from the nozzle,
try the following solutions:
• 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 hot end.
• 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. This
will also allow you to see if a piece of
filament is stuck inside the extruder.
