A
Okay,
so
let's,
let's
start
here
so
if
we
go
to
my
log,
this
continuing
large
3d
printer
working
page
working
doc,
we
can
go
into
that
now.
Let's
talk
about
what
we
do
today,
so
we
we
we're
moving
forward
right
along
an
axis
and
that's
that's
really
good.
They
work.
I
mean
the
attachment
to
the
frame
is
solid.
We're
sticking
the
rods
up,
in
fact,
as
spool
holders,
since
they're
nine
feet
thing
is
quite
sizable.
A
Yeah
I
mean
the
axes
seem
to
be
going.
We've
got
the
the
belt
clips
to
finish
so
holger
was
doing
the
metal
version,
which
I
think
is
going
to
work.
How
many
did
you
make
of
those.
A
A
Yeah,
we're
gonna
mass
produce
more
belt
clips
the
pegs
themselves
to
attach
to
one
side
of
the
belt
that
works
right.
We
don't
have
questions
about
that.
We
print,
can
we
printed
some
smaller
ones,
or
are
we
just
keeping
the
large
ones
or
we
can
use
smaller
ones?
Okay,
we
can
looks
like
we
can
use
the
large
ones
too.
A
So
what
are
some
of
the
next
steps,
so
mass
production
on
the
axis
there's
two
more
on
the
z
with
the
with
the
solid
rods
and
then
there's
three
axes
for
the
x
x
y
y
perpendicular
to
that
well
on
the
other
sides
and
then
spanning
for
the
bed,
but
before
we
do
any
of
that,
let's
get
the
controller
right
out
to
see
if
we
can
drive
one
axis
and
then
four
of
them.
How
do
you
drive
four?
A
You
can
do
in
series,
you
can
wire
it
in
series,
not
parallel
so
in
series,
but
you
have
to
rewire
it
a
little
bit
like
we'd
have
to
rewire
it,
and
how
do
we
do
it?
Just
mechanically
use
the
cat5
wire.
A
A
You
four
sets
of
two,
so
we
just
connect
two
they're
kind
of
thin
they're
rated
for
two
amps
and
closed,
but
they
are
actually
rated
for
more,
like
four
amps
unenclosed,
basically
like
wires
like,
if
you
have
a
single
wire
you
can
handle
like
double
the
power
as
opposed
to
you
having
it
in
a
bundle
of
wires,
but
just
for
safety.
Let's
do
like,
let's
solder
together
two,
so
we've
got
the
white
wires
going
to
one
motor
to
the
next
one
to
the
next
one
to
the
next
one.
A
A
So
here's
the
advantages
and
disadvantages
in
series:
you
can
run
one
stepper
driver
or
four
motors,
because
you're
putting
out
four
amps
at
max
each
motor
gets
up
to
4
amps.
If
you
were
in
parallel
you're
dividing
that
you'd
need
16
amps.
Those
controllers
are
not
16
amps.
So
the
only
way
you
can
do
it
if
you
use
one
driver,
even
if
you
use
two
drivers,
you
need
four
drivers.
You
basically
need
to
multiplex
a
single
output
of
the
ramps
to
four
of
the
large
stepper
drivers.
A
A
A
A
What
shows
up
on
amazon
yeah,
these
ones,
4.2
amp?
What's
their
they're,
the
version
which
has
port
one?
That's
not
the
one.
We
have
that
one
is
425
ounce
inch.
A
A
A
I
guess
yeah
the
this
1900
this
one
that
we
used
that's
the
same
motors
there.
So
what
do
we
do
here?.
A
That's
one
we.
E
A
A
A
A
It'll
start
stretching
or
I
mean
won't,
have
the
infinite
lifetime
like
it
should,
but
we
can
definitely
do
like
68.
That's
what
this
thing
has.
So
in
fact,
our
bed.
We
can
probably
move
it
with
one
stepper
motor
like
this.
Possibly
we've
got
four.
We
should
be
all
good,
but
that's
what
we're
talking
about
and
their
amperage
as
here
it
was
only
2.8,
so
we're
well
within
the
specs
of
the
stepper
driver,
and
it's
called
the
tb
6600
stepper
driver
it's
standard.
C
A
This
is
from
the
fab
lab,
so
you
can
build
one
of
these
too.
It's
the
same
thing.
It's
the
same
that
long
chip
there
that's
the
logic
unit
there.
It
needs
a
big
heat
sink
and
all
that
that's
what's
doing
the
switching,
but
you
can
do
it,
but
here
you
got
it
all
packaged
up
like
this
from
amazon
for
eight
dollars
get
it.
So
the
question
is:
how
do
you
wire
motors
in
series
and,
first,
how
do
you
wire
up
the
stepper,
the
large
stepper
drivers
at
all,
so
we
go
to
the
universal
controller.
A
A
We
took
off
the
small
stepper
drivers
from
the
ramps
and
we
use
three
wires
per
there's
like
three
wires
and
they
connect
to
the
tb
6600
and
the
tb
6600
are
powered
by
this
larger
power
supply,
because
now
we
need
2.8
times
four.
No,
it's
times
seven
three
times
seven
about
20
amp,
21
amps,
so
you
have
to
have
a
power
supply.
A
That's
like
over
20
amps,
like
30
amp
power
supply
because
they're
all
on
at
the
same
time,
once
you
engage
them,
they
just
stay
on
whether
they're
moving
or
not
they're
using
energy,
so
you're
using
30
amps
times,
24
volts,
that's
actually
quite
a
bit
of
power,
you're
already
using
30
amps
times
24.
That's
like
700
watts
right
there
for
the
motors
that
are
just
on
the
whole
time.
You're
printing,
so
that's
actually
gets
to
be.
An
energy
sink,
takes
a
bit
of
energy
to
do
that
compared
to
the
small
ones.
A
The
small
ones
use
like
nema,
oh
yeah,
but
actually
yeah,
that's
about
it.
It
won't
be
like
720,
it's
not
that
much.
It's
maybe
like
50,
50
watts,
each
or
so
the
tiny
ones
they're
only
like
5
or
10
10
watts,
like
5
watts
or
so
so,
like
the
small
printers,
we
have
they're
much
more
energy
efficient.
This.
This
now
you're
getting
too
much
stronger
motors,
much
much
more
energy
requirement.
So
we
need
this
separate
power
supply,
but
we
actually
have
this
whole
setup
already.
A
D
B
A
From
the
arduino
the
power,
that's
the
power
handling
stage
the
drivers,
they're,
actually
power
handling
stage.
The
signals
are
actually
coming
from
the
the
arduino
right
arduinos
through
its
library,
stepper
driver
library.
It
does
the
very
rapid
on
off
sequence,
to
drive
a
stepper
motor
like
at
like
megahertz
or
kilohertz
scale,
or
whatever,
oh
okay,.
A
Okay,
so
on
our
system,
we're
gonna
have
to
plug
in
the
first
one
there,
which
is
the
extruder.
You
see
that
one,
that's
the
extruder
driver
that
we
still
need.
C
F
A
A
A
B
A
A
A
Series
so
we'll
get
to
that
next,
that
that
means
that
four
wires
are
coming
out
of
the
stepper
driver
they're
going
to
one
motor
and
it's
kind
of
splits
but
splits
in
a
weird
way.
You
got
to
follow
where
the
phases
are
and
all
that.
But
it's
easy.
We
got
a
diagram,
so
we
already
figured
that
part
out.
A
So
yes,
you
can
run
four
out
of
the
that's.
Let's
call
these
x
y
and
z
in
that
order,
so
this
last
z,
which
is
plugged
into
there
that's
the
z,
we're
gonna
run
four
in
series
out
of
that
one
for
the
y,
we're
gonna
run
two
in
series
or
in
parallel.
If
we
wired
up
another
one,
let's
just
run
them
in
series
two,
because
then
we
don't
need
an
extra
driver
here,
so
we
can
run
them
in
series
and
then
for
the
x
there's
one
for
the
extruder.
We
can
use
the
tiny
one.
A
A
We
know
that
this
is
already
fixed
up
for
24
volt
operation,
because
we
already
ran
this.
We
might
want
to
check
on
that
that
diode
is
snipped
there
just
in
case,
but
this
should
be
a
24
volt
system.
Well,
actually,
actually,
no,
no
look
at
that.
It
says
12
volts,
one
amp
now,
24
volt.
I
don't
know
this.
This
power
supply
does
both
12
and
24..
A
Yeah,
so
just
want
to
verify
that
if
we're
running
on
24-
which
is
that's
what
we
want
to
do
like
for
12
amps,
we
would
not
support
the
extruder
heater.
We
want
to
still
support
the
extruder
heater
without
burning
out
the
board.
The
same
logic
applies
here,
so
we
got
to
be
running
24.
Let's
make
sure
that
diode
is
snipped.
Now
here
we
might
have
been
running
12
because
the
torch
table
does
not
have
that.
We
use
this
for
the
torch
table
and
that
does
not
have
the
heater.
A
A
A
A
There's
two
things:
one:
how
do
you
wire
tb60?
This
is
the
second
one.
Let's,
let's
take
a
look
at
first,
how
we
wire
a
single
one
so
for
tb
6600
we
want
to
look
at.
How
do
you
wire
a
single
one?
So,
let's
go
to
tb.
F
A
F
F
A
Because
we
want
to
see
these
things
move
like
pretty
quickly,
we
just
got
to
do
those
wires.
I
mean
we'll
start
with
one
just
start
once
and
just
make
that
thing
move
and
make
sure
we
know
what
we're
doing
and
you'll
see
how
much
force
it
has.
It
actually
has
quite
a
bit
of
force
on
it.
So.
A
So,
what's
going
on
there,
this,
the
little
driver
would
be
like
one,
two,
three,
four,
five,
six,
seven,
eight
pins.
So
you
you
can
recognize
this
on
the
board.
Just
follow
this
diagram.
So
this,
let's
call
them
like,
pin
one
through
eight
on
top,
then
continuing,
maybe
9
through
16
on
the
bottom,
so
pin
8.
Here
this
black
one
goes
into
pull
step
direction,
enable
that's
ground.
A
This
one,
which
is
like
15,
goes
into
this
one.
These
are
labeled
with
these
labels.
Pulsing
you
got
to
pulse
this
thing.
You
got
to
give
it
a
direction
you
got
to
enable
it
meaning
turn
it
on.
So
there's
three
wires
three
sets
of
wires
and
then
the
three
black
are
ground.
So
that's
the
ground
connection.
Well,
the
three
ones
are
so
called
this
purple.
Nine,
that's
enable
15
is
going
to
be
your
pulse
or
step
and
then
16
is
going
to
be
your
direction.
A
A
A
B
B
A
Yeah,
that's
probably
what
it
does
yeah
now,
the
height
the
other
side
is
high
voltage.
So
if
we
actually
look
at
amazon
like
a
close-up
of
amazon,
so
you
can.
A
A
E
A
E
F
F
A
B
A
A
B
A
We
only
need
to
do
that
once
why,
because
mechanically
we
set
up
all
the
z-axes
like
if
the
belt
peg
is
on
the
right-hand
side
like
it
is
on
the
first
axis
we
did.
The
belt
peg
must
be
on
the
right
hand,
side
on
the
other.
If
they're
gonna,
the
motors
have
to
go
on
all
in
the
same
direction,
so
you
have
to
make
it
on
the
right
hand,
side
right
hand,
side,
and
then
we
go
around
to
the
other
side.
A
A
A
B
A
A
So,
what's
going
on
there?
Well,
let's
let
me
extract
that
a
little
better.
A
I'm
gonna
do
a
picture
just
enlarge
this,
so
we
see
where
the
wires
are
connecting
right
right.
So
we'll
get
to
understand
that.
D
E
A
So
I
don't
know
like
this:
is
this
kind
of
diagram
is
useful,
just
just
copy
and
paste
one
of
them
just
to
to
understand
that
there's
two
windings
but
they're
connected
in
like
they're,
two
two
are
connected
and
two
are
connected.
A
A
A
A
A
If
there's
two,
then
this
would
be
going
back
to
your
that's
your
other
pair
and
your
pair
of
wires
for
that
winding,
so
that
so
here,
let's
let
me
draw
like
one
pair
of
windings
would
be
I'm
gonna
put
this
in
red.
A
F
D
F
A
D
A
F
A
F
But
the
diagram,
it's
it
shows
you
how
to
connect
with
that
series.
I.
A
There,
okay,
so
we
need
to
add
this
to
our
there
we
go.
A
A
A
A
So
if
you
can
understand
this,
you
can
do
this.
I
mean
just
follow
this
picture,
but
but
understand
the
logic,
because
this
requires
manual,
dexterity
or
just
like
manual
like
physical
reality
and
logic.
At
the
same
time,
so
you
kind
of
have
to
do
that
and
some
people
don't
do
that
so
or
it's
like
tough
to
learn
that
because
you
using
like
multiple
parts
of
your
brain
which
were
skilled
away
from
doing
typically.
E
A
A
Yeah
yep,
that's
it
questions.
Let's
get
out
there.
C
One
question
just
curious:
the
the
small
motors
that
we
used
before
there
are
four
times
less
powerful
than
the
motor
on
the
big
guy.
At
the
torque
I
mean.
A
A
You're
looking
at
like
cross-sectional
areas
and
magnetic
flux-
and
it's
like-
I
would
say,
flux
would
scale
because
it's
three-dimensional,
it
would
should
scale
as
cubic.
So
you
should
in
principle,
have
like
a
cubic
ratio
of
power,
but
it's
not
because
it's
like
more
like
four
times
the
size
for
four
times.
It
should
be
like
eight
times
the
size.
Well,
actually,.
F
A
Never
made
it
here.
No,
this!
This
is
our
plan.
This
is
our
50
kilowatt,
universal
rotor.
On
a
pole,
that's
okay,
yeah,
the
other
stuff
is
elsewhere,
but
we
can
use
the
same
the
same
universal
rotor.
We
are
using
right
now
and
make
a
big
structure
like
this.
So
do
this.
This
is
what
you're
going
to
do.
Basically,.
F
A
A
If
we
had
some
time,
we
can
put
the
super
volcano
on
it
and
start
driving
super
volcano
four
times
faster,
yeah,
oh
bigger,
heater
blocks,
but
we
do
have
the
heater
block
and
if
we
have
any
time-
but
I
mean
we're
we're
out
of
time-
we
don't
have
anybody
out
there
so,
but
we
do
have
the
large
heater
block
which
gets
you
not
five
pounds
but
20
pounds
per
day,
so
that's
getting
into
production
yeah.
D
A
A
But
we
have
do
have
I
mean
this
is
interesting
stuff.
This
is
future
work
here,
but
scalable
scalable
heater
block,
because
we
do
everything.
That's
scalable
study
this
put
a
few
of
the
small
ones
that
we
use
right
now
together
and
do
this.
F
D
A
A
A
This
would
probably
work.
This
is
pushing
it.
I
talked
to
the
guys
that
do
this
from
e3d.
They
got
this.
