Please
make
sure
you
really
move
the
Z
carriage
up
to
the
end
stoppers
until
you
hear
a
rattling
sound
as
the
Z
stepper
motors
skip
steps.
This
procedure
ensures,
that
1)
the
X
axis
is
perfectly
horizontal,
2)
the
nozzle
is
in
a
known
distance
from
the
bed.
In
case
the
Z
carriage
did
not
touch
the
end
stoppers,
the
printer
could
not
possibly
know
the
height
of
the
nozzle
above
the
bed
and
it
could
therefore
crash
into
the
bed
during
the
Z
calibration
procedure.
The
Z
calibration
procedure
also
prompts
you
to
"Please
clean
the
nozzle
for
calibration.
Click
when
done."
If
this
advice
is
not
followed
and
there
is
a
plastic
debris
on
the
nozzle,
then
the
debris
may
touch
the
bed
or
even
push
the
bed
away
from
the
PINDA
probe,
so
the
PINDA
probe
will
not
trigger
properly
and
the
calibration
will
fail.

Mesh

levelling
Mesh
bed
levelling
can
be
found
in
Calibration
menu.
It
is
the
same
procedure
which
is
performed
before
every
print.
You
can
use
it
to
check
the
P.I.N.D.A.
probe
alignment
with
the
calibration
points
however
it
is
not
necessary
during
the
calibration
process
as
Mesh
bed
leveling
is
a
part
of
Calibrate
XYZ
and
Calibrate
Z
routines.
Before
running
this
command
clean
the
nozzle
tip
from
any
debris
and
run
it
while
the
nozzle
is
cold.
If
the
probe
is
misaligned
and
the
nozzle
is
preheated,
the
nozzle
can
make
permanent
impressions
in
the
surface.

The

must
be
inside
the
circles
(1st
and
9th
calibration
point)
to
successfully
level
the

.
