FILAMENT NOT LOADING
If you are having problems loading lament
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
lament. It is important that the lament
have no bends in it. If there are bends, cut
o the bent section of lament.
4. Insert the lament 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 lament 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 lament from the top of
the extruder and check for a bend at the
end of the lament. If the lament 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 lament travel
through the extruder and determine
where the lament is getting stuck. This
will also allow you to see if a piece of
lament is stuck inside the extruder.
