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.
