hits
the
back
of
the
nozzle.
e. Select
Setup
>
Preheat
PLA.
f. When
the
printer
is
fully
heated,
remove
all
of
the
filament
color
left
in
the
printer
from
previous
prints
before
you
start
a
new
print.
To
do
this,
manually
push
filament
through
the
extruder
as
you
squeeze
the
extruder
release
lever
until
the
new
color
starts
coming
out
of
the
nozzle.
Pro
Tip
:
Never
leave
the
printer
preheated
with
material
inside
of
it
when
it
is
not
printing.
The
filament
will
bake
inside
of
the
nozzle
assembly
and
create
a
clog.
2. Removing
filament
To
remove
the
filament
cleanly,
you
should
do
a
“soft
pull.”
This
involves
heating
the
nozzle
to
100°C,
then
pulling
the
filament
out
of
the
printer.
a. Select
Setup
>
Preheat
soft
pull
and
wait
until
the
nozzle
temperature
reaches
the
set
temperature
b. Wait
a
minute
for
the
temperature
to
become
stable.
c. When
the
nozzle
temperature
is
a
stable
100°C,
squeeze
the
extruder
release
lever
and
pull
the
filament
out
of
the
extruder
with
a
steady,
firm
motion.
d. Cut
the
end
of
the
filament
to
remove
the
irregular
melted
plastic
at
the
end.
Pro
Tip
:
Feed
the
end
of
the
filament
into
the
hole
on
the
side
of
the
spool.
This
will
insure
it
doesn’t
get
tangled
and
cause
a
build
to
fail
the
next
time
you
use
it.
e. Remove
the
filament
from
the
filament
spool
holder.
