We've
got
the
end
stops
which
are
limit
switches.
They
activate
upon
the
axis
going
all
the
way,
so
they
determine
the
end
point
location,
so
we're
gonna
plug
in
the
wire
to
that
stop.
It
only
goes
in
one
way
so
plug
that
in
and
then
take
your
and
stop
holder,
which
is
magnetically
attached
and
slide
the
slide.
The
end
stop
into
it
in
a
way
that
the
lever
is
exposed
to
the
carriage.
So
how
is
that
gonna?
Be
it's
gonna
be
like
that
slide
it
in
from
the
bottom,
for
the
x-axis.
A
A
It
does
matter
which
pen
is
which
so
you
have
to
determine
whether
you're
talking
about
the
print
cooling
fan,
which
is
the
large
fan
or
the
small
fan
on
the
side,
which
is
the
heatsink
cooling.
Then
they
go
in
two
different
locations.
So
maybe,
let's
that's
actually
maybe
I'll
go
through
this
quickly
as
far
as
where
they
go.
How
about.
B
A
A
A
A
A
A
Okay,
you
can
trace
it
by
by
knowing
that
the
one
I
got
spliced
on
is
the
one
from
the
big
fan.
The
big
fan
makes
a
permanent.
No,
it
doesn't
make
a
permanent
connection.
It
goes
into
d9,
so
what's
gonna
going
to
strip
that
plug
it
into
d9
and
there's
a
plus
or
minus,
and
we
have
to
look
at
that.
The
original
one
is
labeled.
These
are
not
labeled,
I,
believe
the
losses
are
not
inside
so
d9
for
the
big
plan.
B
A
All
the
time,
because
any
time
the
printer
is
running,
you're
gonna
need
to
make
sure
that
the
heatsink
is
cool,
while
the
hot
end
is
hot,
so
this
being
on
all
the
time
we
plug
it
into.
Actually,
we
don't
have
any
pins
that
are
on
all
the
time
here,
so
we
actually
want
to
cut
this
at
the
end,
because
we
want
to
plug
it
in
permanently
to
a
positive
12.
That's
what
happens
there
next.
A
A
So
extruder
is
the
second
it's
this
one
right
here.
This
is
X.
This
is
extruder.
This
is
y
and
y,
and
this
is
Z
Z.
There
are
two
plugs
right
on
this
next
to
the
seat.
Next,
to
one
another
sulfur,
that's
cruder,
we're
going
in
here
and
the
direction
will
matter
right
now.
I,
we
don't
have
a
convention
for
which
we
don't
know
which,
which
way
up
or
down,
is
right.
It
can
plug
in
up
or
down
either
way
so
that
that
goes
there.
This
for
the
extrusion
continuing
on
to
the
X
motor.
A
A
And
the
plugs
are
kind
of
small,
so
you
kinda
have
to
look
closely
there
to
make
sure
you're
on
it.
Sometimes
you
might
miss
it
and
the
stuff
that
won't
work
you'll
be
scratching
your
head.
Then
you
look
at
make
sure
the
plug
is
plugged
in
correctly
the
first
troubleshooting
step,
so
this
person
so
last.
A
A
So
we're
activating
you
to
use
different
cables,
but
they
plug
in
right
and
look
at
the
bottom
stepper
driver,
which
has
two
rows
of
pins,
so
one
for
this
side
and
then
other
one
from
this
side
here
right
next
to
it
with
a
thin
black
plug.
This
plug
here
does
not
work
because
it's
too
fat,
you
won't
get
two
of
them
right
next
to
each
other.
So
that's
that
the
only
remaining
thing
now
so
we
got
the
keypad
thermistor
keep
by
determinant
goes
underneath
the
extruder
thermistor.
So
this
is
good
before
yeah.
A
A
A
The
second
one
goes
into
the
actually,
it's
the
fourth
pens,
so
there's
X
minimum
X
maximum.
You
can
have
the
end,
stop
on
minimum
or
maximum
position,
so
we
can
trip
on
the
lower
side
or
trip
on
the
high
side
here,
we're
tripping
where,
if
we're
tripping
to
access
the
middle,
the
left
hand
side,
that's
the
machine,
that's
ex
my
ex
origin.
That's
moving
up
the
neck,
so
it's
X
minimum
position.
In
other
words,
it's
the
first
set
of
pins
for
the
end
stops
now
for
the
Y.
This
is
actually
the
max
of
the
Y.
A
So
if
you
look
once
again
the
connection
right
here,
the
origin
is
here.
So
that's
the
maximum
X
and
the
pin
set
goes
there.
X
min
x,
max
Y,
min
Y
max
so
Y
max
is
the
fourth
in
position
down.
So
this
goes
into
the
fourth
pin
set
out
of
those
such
as
so
the
fourth
pin
set,
and
then,
where
does
the
Z
plugin?
So
we
talked
about
the
Z
before,
but
the
Z
will
plug
in
into
the
Z
men,
because
it's
closest
to
the
the
convention
is
the
closest
to
the
printhead.
