Printing
● Make
sure
that
the
nozzle
and
the
bed
are
heated
to
the
desired
temperature.
If
you
forget
to
preheat
the
printing
nozzle
and
the
bed
before
printing,
the
printer
will
automatically
check
the
temperatures
of
the
nozzle
and
the
bed;
printing
will
start
when
the
desired
temperature
is
reached
-
it
can
take
several
minutes.
However,
we
recommend
preheating
the
printer
beforehand
as
described
in
the
chapter
Do
not
let
the
preheated
printer
idle.
When
a
printer
is
preheated
and
non-printing,
material
in
an
extruder
degrades
over
time
-
it
may
cause
the
nozzle
to
jam
up.
● Watch
the
first
few
printed
layers
to
be
sure
filament
has
attached
to
the
bed
properly
(5
to
10
minutes).
● Press
the
LCD-knob
and
choose
the
from
SD
option
from
the
menu,
press
to
confirm
and
pick
the
desired
model
file_name.gcode
.
The
printer
will
start
printing
the
object.
The
filename
(.gcode)
must
not
contain
any
special
characters
otherwise
the
printer
is
not
able
to
display
the
file
on
the
LCD.A
list
of
acceptable
characters
would
be
clearer
7.1
Removing
objects
from
the
printer.
Removing
prints
from
the
build
plate
is
much
easier
because
of
the
ability
to
remove
and
bend
the
build
plate.
Different
thermal
expansion
of
the
steel
sheet
and
plastics
used
in
3D
printing
also
helps
with
detaching
prints
after
the
plate
has
cooled
down.
● When
printing
is
finished,
let
the
nozzle
and
heatbed
cool
down
before
removing
the
printed
object.
Always
handle
the
printed
objects
when
the
temperature
of
the
bed
and
nozzle
drop
to
room
temperature.
When
the
bed
is
hot,
objects
are
very
hard
to
remove.
Remove
the
steel
sheet
from
the
printer
and
bend
it
slightly;
prints
should
pop
off.
● If
you
experience
any
troubles
removing
the
object
(especially
the
small
ones),
you
can
use
a
flat
tool
like
a
spatula
with
rounded
corners
to
prevent
damage
to
the
PEI
.
Slide
the
spatula
under
the
corner
of
the
object
and
gently
push
until
the
pops
off.
