A
All
right
so,
let's
start
actually.
B
C
A
Printers
we're
working
on
actually
printing
parts
for
the
torch
table,
so
that's
that's
kind
of
the
bootstrapping
route.
B
B
D
To
20
21.08,
so
concept
design.
So
let's
start
with
this
dot
here
so.
D
B
D
D
B
D
Those
are
the
immediate
things
and
a
bunch
of
the
heavy
equipment
parts
like
backhoes
and
things.
This
is
a
critical
tool:
here's
the
genealogy
for
the
torch
table;
okay,
what.
D
From
last
time,
the
video
design.
B
D
B
More
transparent,
like
from.
D
C
B
Which
means
you,
you
span
the
x,
the
y
axis
here
kind
of
have
it
reversed.
It
should
really
be.
The
y
axis
here
should
be
x.
The
way
we
if
we.
D
B
X,
not
underslung,
put
the
x
in
between
the
y
axis
this
time
around
things.
B
C
B
D
A
B
D
C
A
D
B
D
Just
simply
the
belt
runs
around
it.
It's
the
third
piece
of
the
universal
axis
like
there's
the
motor
piece,
the
carriage.
A
B
A
B
A
C
C
B
B
B
D
B
D
A
D
D
Yeah
both.
A
D
B
This
piece
so.
A
B
D
B
A
D
A
D
A
D
B
A
B
A
B
C
B
B
D
B
Then
you
have
a
bearing
a
bearing
hole,
so
we'd
pop.
We
could
pocket
that,
for
example,
to
the
length
of
the
bearing
what's
the
bearing
length
1.25.
D
A
D
B
Keep
it
there,
how
do
you
keep
it
there?
The
standard
technique
that
we
used
before
is
the
the
universal
idler
carriage
closure.
So
this
could
look
a
little
different
here.
We
can
use
these
bolts
here
for
carriage
closure.
So
say
we
just
did
this
here.
We
already
have
these
bolts
here
that
candid
so-
and
this
is
all
for
m6
bolts,
they're
printed
as
about
5.5
millimeters,
so
you
actually
thread
into
them.
B
So
the
concept
here
is
everything
threads
in
now.
You
might
see
the
challenge
here.
These
are
5.5
and
you're.
Attaching
this
idler
piece
which
you
would
want
to
do
is
take
a
six
millimeter
bit
and
ream
these
out,
so
that
the
bolt
goes
through
and
starts.
Catching
starts
catching
threads
on
the
idler
here.
If
that
makes.
A
C
B
Put
a
put
a
thing
on
it:
that's
got,
let's
draw
one
out
that
would
be
in
the
x
y
axis.
B
So
what
what
what
would
it
look
like?
It's
just
a
square
thing
put
it.
B
C
B
D
A
B
It
would
look
something
like
this:
that's
your
closure,
so
it
allows
the
rods
to
go
freely
through
it
and
then
you
need
the
appearance
yeah.
I
actually
drew
a
feature
on
this,
so
that's
that's
not
a
proper
closure.
That's
a!
I
need
to
draw
a
separate
piece
there,
because
the
whole
thing
lights
up
here,
but
I
just
wanted
to
show
the
appearance
here,
a
little
transparency.
B
So
that's
what
you
got
there.
So
we've
got
this
bearing
hole
in
there.
You
got
the
closure,
but
we
need
to
poke
some
bolts
for
this
closure
as
little
as
like.
Maybe
this
bolt
see
that
bolt
there
and
like
two
bolts
there
would
suffice.
B
B
D
B
There's
little
flanges
on
the
motor.
If
you
look
at
the
details
so
so
you
can
send
the
bolt
right
through
the
back
and
thread
it
into
the
plastic
3d
printed
piece,
so
that
would
work
those
are
what's
the
size
of
those
holes.
It's
like
they're,
like
four
millimeter.
I
believe
something
like
that.
So
so
tiny
bolts
that
go
in
there.
A
Yeah,
but
I
was
troubled
by
this
thing
here-
that's
nine
hours
for
this
print.
We
want
to.
B
A
B
C
A
A
If
you
got
100
pounds
to
hold
so
this
would
definitely
help
you,
but
we
just
might
want
to
start
cutting
out
around.
B
E
B
D
D
Didn't
save
it
right,
export.
B
D
B
D
D
B
E
You
can
so
this
is
the
kira,
the
old.
C
B
D
A
B
B
B
A
B
Eight
dollars
you
can
make
these.
This
is
actually
open.
C
D
A
D
C
A
D
B
A
D
A
D
D
C
E
B
B
B
Black
here
is
ground,
so
you
got
on
the
step
driver
you
get
the
labels
like
pulse
direction
and
enable
so.
C
B
A
C
D
C
B
Sequence,
you'll
see
probably.
C
B
C
E
B
B
A
B
B
A
B
Motor
like
more
at
a
lower.
A
C
D
B
A
A
E
D
B
B
D
D
B
A
D
B
Between
carriage.
B
B
D
B
E
B
D
A
B
Go
into
say
you
go
into
cura,
you
have
the
ready
ability
to
do.
B
You
can
download,
for
example,
you
can.
A
A
B
A
D
B
B
Is
like
too
crazy
here,
so
this
could
work,
but
it's
it's
a
little
too
long.
So
probably
just
redesign
this
and
it's.
B
C
B
What
we
have
before,
except
you'd,
have
to
once
again,
because
the
belt
is
much
wider.
This,
if
you
use
the
reference
design
from
the
before
make
the
make
this
slit
here
just
longer,
so
it
can
accept
the
15
millimeter
belt,
so
that
will
be
the
design
change
there
and
then
you
need
to
add
the
carriage
closure,
as
I
talked
about
belt-
clamp
so
a
convenient
way
here.
So.
D
B
D
B
B
Once
again,
if
we
extend
this
piece,
so
these
bolt
holes
actually
work,
you
use
a
50
millimeter
bolt.
D
B
The
hardware
store
cool
thing
is
you
can
use
m6
or
a
quarter
inch?
The
threading
does
not
mind
six
millimeter
compared
to
six
point:
two:
five
millimeter,
that's
what
quarter
inches
quarter
inches
six
point
two
five
millimeter
or
something
close
to
that
both
bolts
would
work.
So
this
is
readily
accessible
for
off-the-shelf
hardware,
if
you
use
a
two-inch
bolt
so
now,
if
you
have
a
two-inch
bolt
though-
and
this
is
40
millimeters,
then
you're
threading
in
only
10
millimeters
you'd
like
to
thread
in
a
little
more.
B
B
D
You
just
yeah,
you
took
out
some.
B
B
And
you
can,
if
you
put
a
bolt
through
it,
you're
getting
gaining
yourself
a
few
millimeters
there
so
that
you
would
thread
in
maybe
like
15
millimeters.
B
Like
to
see
the
thread
in
like
maybe
like
20
millimeters,
like
close
around
three
quarter
inch,
so
that
you
make
sure
that
when
you
thread
it
in
it's
not
coming
out
it's
a
very
solid
connection,
I
would
say
about
20
millimeters
of
threading
would
be
good,
so
we
have
to
think
about
both
sides
bolt
holes.
Now
you
can
use
a
longer
bolt
like
60
millimeter,
or
you
know
two
and
a
half
inch
or
something
yes,
sure
we're
just
trying
to
use
very
common
parts.
B
So
that's
one
consideration
there
as
far
as
so,
the
idler
wants
to
clamp
just
one
more
thing
here.
What
I
would
modify
here
is
on
the
idler.
You
want
to
grab
the
rod
by
clamping
it
down.
B
Through
the
side
and
you've
got
a
little
you've
got
there,
you
have
about
a
quarter
inch
about
six
millimeters,
seven
or
maybe
seven
millimeters
there,
where
you
can
grab
a
bolt
onto
that.
But
what
I
would
do
here
make
that
more
solid
of
a
connection.
So
I
would
build
up
this
side
here,
build
this
up
like
this,
give
it
a
little
pad
and
then
poke
through
it.
So
you've
got
much
more
meat.
If
you
want
to
stick
a
bolt
through
this,
so
now
we're
gonna
do.
B
B
D
B
Well,
that's
what
we're
doing
the
equivalent
of
in
this
case
here
we
actually
connected
pieces
through
the
four
four
bolt
pattern.
This
is
the
original
one
with
a
nema
17
motor.
I
use
these
belt
pegs.
We
went
away
from
the
belt
pegs
because
they
have
to
be
very
precise.
Otherwise
they
fall
out
or
are
too
tight,
but
that's
the
equivalent
and
you're
kind
of
thinking.
Okay,
you've
got
the
motor.
You've
got
the
idle
idler
here
here.
We
actually
use
this
long
idler.
B
Just
just
for
reference
of
what
what
we're
trying
to
accomplish
here,
so
you
can
make
the
analogy
between
one
one
system
and
the
other,
and
in
this
system
here
we
have
double
clam
shell.
So,
for
example,
here
you
need
these
four
bolts
to
clamp
it
together.
B
Axis
we're
just
going
to
larger
size
and
using
larger
stepper
drivers,
and
you
can
use
larger
frames
and
then
you've
got
you're
on
top
of
making
pretty
decent
sized
machines
on
order
like
the
limit
of
the
one
at
one
inch
axis
would
be.
You
can
probably
do
very
easily.
B
I
would
keep
it
at
four
feet
by
four
feet
and
eight
feet.
Tall
is
easy.
B
If
you
go
to
longer
lengths
like
say
you
wanna
do
still
one
inch
universal
axis
torch
table,
which
is
longer
than
four
by
four
feet,
use
hollow
rods.
They
do
have
one
inch
hollow
rod,
which
is
much
lighter,
because
the
the
thing
that
happens
is
with
one
inch
solid
rods.
They
end
up
sagging,
we
did
a
torch
table
that
was
like
10
feet
long
and
to
show
you
that
one
d3
cnc.
B
A
A
A
C
B
C
D
D
D
B
B
A
D
Wood
or
something
that'll
be
kind
of
the.
C
B
D
Okay,
so
that's.
C
No
questions
just
really
looks
good.
The
the
the
monolithic
parts.
Aside
from
the
clam
shells
I
mean,
I
think
that's
definitely
gonna
be
easier
to
do.
B
B
A
B
A
B
D
B
Break
or
not
because
those.
B
D
D
We'll
we'll
actually
get
out
the
large.
A
B
Like
you
know,
like
10
or
20
bucks,
but
in
units
of
multiple
they're,
like
eight
bucks,
each
you
need
a
12
or
24
volt
power
supply.
D
D
B
C
C
D
D
E
D
B
B
A
B
B
Like
the
stem
diy
stuff,
yeah
and.
B
Stepper
motors
with
arduino
it
will.
B
C
This
might
be
jumping
a
little
bit
ahead,
but
does
the
controller
also
control
the
actual
torch
head
on
and
off.
D
B
B
E
B
B
They
can
be
run
with
those
three
outputs
there.
You
can
turn
on
an.
B
B
D
B
B
B
C
A
B
Already
built-in
ability
to
control
stepper
motors
and
larger
stepper
motors,
so
it's
like
what
else
do
you
need?
You
need
inputs?
You
need
to
control
things
as
signals
through
outputs
that
you
can
run
through
power,
handling
elements
like
transistors
or
solid-state
relays
or
mechanical
relays.
So
yeah,
that's
only
very
cool
yeah
with
the
lcd.
You
can
program
that
to
to
say:
okay
now
this
is
the
torch
table
program
firmware.
So
that's
for
programmers
like
anybody
who
wants
to
help
us
with
that.
We
can
do
it
otherwise,.
C
B
Use
the
exact
like
right
now
just
running
marlin,
the
g-code
that
you
do
for
the
two-dimensional
motion.
You
can
run
this
exactly
with
a
marlin
firmware.
You
can
run
exactly
the
same
3d
printer
code
and.
C
B
D
B
So
I
think
I
think
it's
a
bottle
so
I'll
come
down
here,
we'll
take
out
some
of
the
stepper
drivers,
larger
ones
and
we'll
we'll
see
if
we
can
get
those
working
with
a
larger
motor
and
that's
about
it.
So
we
can
run
larger
machines.
B
B
This
torch
table
design
lesson
we'll
go
from
here,
see
what
we
can
do
today.
D
E
Quick
question:
please:
yes,
could
you
just
run
through
the
procedure
to
change
the
free
cad
fcstd
to
stl?
You
know
making
solid
and
come.
I
I
keep
getting
yeah.
B
B
Effectively,
what
you're
looking
for
is
you
just
see
that
everything
is
lit
up
so,
in
other
words,
this
pocket
here
contains
all
the
information
so
yeah
you
can
go
like
you
can
export
this
as
a
simple
object.
But
no
you
don't
need
to
do
that.
As
long
as
you
have
everything
selected
and
if
it's
in
multiple
parts
you
can
go
into
the
part
tree
and
then
select
multiple
parts
by
hitting
control
so
say
you
did
have
more
pieces
that
were
part
of
the
object.
You
want
to
print
what
I'm
doing.
E
Could
you
say,
do
it
with
the
with
the
carriage
piece.
B
I
I'm
gonna
go
to.
B
B
B
D
B
The
bearing
holes
in
here
right,
so
this
is
in
progress,
the
bearing
spacer,
but
the
bearing
this
is
one
inch
rod
right.
So
you
were
in
process.
E
B
E
Bearing
okay,
then
that
throws
off
the
the
holes
the
attachment
holes,
maybe.
B
B
E
B
B
It's
just
this
is
just
getting
stripped
down
to
the
essential
features
which
is
good
so
that
if
we
need
to
modify
it,
one
easy
way
to
do
it
is
you
know,
modify
the
existing
pieces
to
a
different
version
for
a
specialized
purpose.
Don't
don't
need
to
do
one
thing
that
does
everything,
but
if
we
make
the
design
very
transparent
easy,
then
it's
very
easy
to
modify
to
different
applications.
