3. Mechanical problem #2: Filament is not coming out of the nozzle
Video Tutorial:
How to remove clogs, load, and change filament
When filament is not coming out of the nozzle, the nozzle may be clogged.
You have three good options for clearing a clogged nozzle:
1. You can pull the clog out of the nozzle using the “soft pull” method.
2. You can “floss” the clog out of the nozzle using a nozzle cleaner.
3. You can heat the nozzle and push the clog through the nozzle.
Pro Tip:
Do NOT remove the nozzle or disassemble the hot end of the
printer when you have a clog. Instead, try these three options. If they
don’t fix the problem, complete a
troubleshooting request
and our
Service Team will help you.
Pro Tip #2
:
Never leave your printer nozzle at build
temperature (220°C) while the printer is idle. The melted
plastic remaining in the nozzle will “bake” onto the nozzle
and become a hard carbon blockage.
a. Try to pull the clog out of the nozzle using the “soft pull” method:
1. Turn the machine on, select Setup > Preheat soft pull, and wait until
the temperature reaches 100°C.
2. When the nozzle temperature stabilizes at 100°C, squeeze the
extruder release lever with one hand and pull the filament out of the
extruder with your other hand with a steady, even force.
3. Inspect the end of the filament. If the end of the filament has the shape
of interior of the nozzle—a thicker cone-shaped plug—you have
successfully pulled all of the filament out of the nozzle, including the
clog.
4. If the clog did not clear using the “soft pull” method, clip the melted
end of the filament off, reload it, and select Setup > Cooldown and wait
five minutes for the hot end to cool down. Then repeat the soft pull
process.
