A
So
next
part
next
part,
so
we
talked
about
the
main
axes,
the
the
carriage
here,
so
we
can
do
the
motor
parts,
let's
do
motors.
So
let's
get
a
bunch
of
motors
and
we
can
all
of
us
put
little
sprocket
on
a
motor
and
you
put
it
down
all
the
way
on
the
motor
and
I'll
show
you
demonstrate
with
one
okay.
So
you
can
use
this
as
a
spacer
but
ideas.
So
we've
got
these
motors
and
and
they're
plug,
which
is
good
so
that
one
plug
goes
in
here.
A
What
I'm
going
to
be
only
to
put
it
on
right
now,
so
we've
got
the
police,
it's
very
simple
one.
Little
simple
interim
step,
put
the
pulley
down
and
tighten
down
the
set
screw,
there's
a
little
element
inside
to
take
on,
but
ideas
that
we
have
to
make
the
fully
aligned
exactly
with
a
hole.
That's
going
out
of
the
pieces.
So
let's
see
what
that
looks
like
or
the
level
yep.
So
we
take
the
motor
piece,
which
is
this,
and
you
know
the
motor
piece
by
the
one.
A
A
A
But
that's
and
and
the
way
you
know
how
deep
the
pulley
is
just
look
at
down
on
home
down
the
middle
of
the
hole,
see
if
it's
aligned,
how
aligned
is
it
it's
actually
pretty
pretty
good,
as
is
so.
Basically,
the
idea
was
so
I
just
verified
that
if
you
just
use
that
as
a
spacer
and
I
want
you
to
use
a
spacer,
because
if
you
put
it
all
the
way
down
a
nitro,
so
so
the
idea
is
take
one
of
these
just
put
the
pulley
on
it.
A
Take
the
little
wrench
and
tighten
it
down
so
to
tighten
then
just
go
by
hand
and
pressure,
so
you
screw
it
store
it
in
the
hand.
Pressure
like
that
and
then
at
the
end,
I
would
just
go
with
the
other
end.
Where
you
got
leverage.
Does
that
get
you
more
mechanical
advantage?
Just
just
do
a
little
more,
not
too
tight.
These
are
tiny
screws.
So
that's
it!
How
many
of
these
do
we
need?
A
How
many
machines
are
we
building
18
times
how
many
steppers
black
see
the
trigger
right,
Plus
extruder,
but
the
extruder
gets
a
different
thing.
That's
that's!
Gonna!
Be
a
drive
wheel
which
is
different
as
extruders
not
driving
a
belt.
It's
driving
this
little
sprocket,
which
is
a
drive
for
the
filament.
So
it's
different.
So
five
of
these
yep
times
five
times
18
so
90.
