Fail
stats
The
printer
keeps
statistics
about
the
failures
it
experienced
and
recovered
from
during
the
last
print.
It
is
useful
for
assessing
a
long
print,
for
example
over
a
night
or
a
weekend,
if
everything
ran
smoothly.
Fail
stats
are
placed
at
the
bottom
of
the
LCD
menu.
Failures
which
are
detected:
● Filament
runout
● Power
panic
● Lost
steps
/
shifted
layers

Normal
vs.
Stealth
mode
The
printer
offers
two
modes.
Normal
mode
is
required
for
the
detection
of
lost
steps
(shifted
layers)
while
still
being
quieter
than
silent
mode
on
MK2/S.
The
second
is
called
Stealth
mode
and
utilizes
Trinamic
StealthChop
technology
making
the
printer
almost
inaudible
with
the
cooling
fan
being
the
noisiest
part
of
the
printer.
Stealth
mode
however,
doesn’t
provide
lost
step
detection.
7.2.6
Factory
reset
The
factory
reset
is

it
to
the
factory
state.

●
Shipping
prep
which
resets
only
the
printer
language
selection.
All
the
calibration
data
including
the
Live
adjust
Z
remain
intact.
Even
though
the
calibration
data
are
still
present
and
functional,
the
printer
will
prompt
the
user
once
to
run
the
Calibrate
Z
function.
This
“light”
factory
reset
is
mainly
used
for
resetting
of
assembled
printers
before
shipping
out
of
the
factory
so
that
users
can
select
their
language
and
run
Calibrate
Z
after
unpacking.
●
All
data
which
resets
everything
including
all
calibration
data
and
the
whole
EEPROM
is
cleaned.
After
this
reset,
the
user
is
expected
to
go
through
the
calibration
flow
again,
except
setting
the
probe
height.
