Regular
maintenance
12.1.1
Bearings
Every
couple
hundred
hours,
the
smooth
rods
should
be
cleaned
with
a
paper
towel.
Then
apply
a
little
bit
of
general
purpose
machine
oil
on
the
smooth
rods
and
move
the
axis
back
and
forth
a
couple
of
times.
This
cleans
the
dirt
and
increases
longevity.
If
you
feel
the
axis
is
not
running
smoothly
anymore,
bearings
can
be
taken
out
and
greased
on
the
inside
(they
need
to
be
removed
from
axis
because
the
plastic
lip
will
prevent
the
grease
from
getting
inside).
Super-lube,
or
any
other
multi
purpose
grease,
will
do.
12.1.2
Fans
Both
fans
should
be
checked
and
cleaned
every
couple
hundred
hours;
dust
or
plastic
build-up
can
decrease
their
efficiency
or
even
damage
them.
Computer
cleaner
spray
will
get
the
dust
away
and
tweezers
can
be
used
for
little
plastic
strands.
Both
extruder
and
part
cooling
fans
measure
current
RPM
(Revolutions
Per
Minute).
Because
of
that,
they
can
detect
any
problem
that
will
cause
the
fan
to
slow
down,
like
a
piece
of
filament
getting
stuck
in
it.
If
you
get
a
fan
error,
check
that
it
can
rotate
freely;
clear
any
debris
that
may
be
stuck
in
it.
