A
So
where
do
we
go
so?
First
of
all,
the
firework
that
we
built
on
here
is
work
on
a
cnc
torch
table.
We've
done
most
of
the
one-inch
universal
access
on
a
torch
table,
so
you
want
to
take
a
look
at
universal
axis.
A
A
Light
you
want
dark,
okay,
so
one
inch
universal
axis
prior
work,
so
so
same
as
the
5
16
inch,
the
eight
millimeter
stuff.
The
concept
is
the
same:
it's
you've
got
bushings
around
rods
and
you've
got
the
motor
piece.
The
idler
piece,
the
carriage
the
carriage,
is,
what
moves
those.
A
A
A
Provides
the
the
precision
motion
around
the
rods
it's
where
the
belt
is
attached,
it's
where
your
tools
are
attached.
So
that's
the
part.
That's
moving!
So
once
again,
three
functions
more
or
less
the
motor
piece
you've
got
the
drive
there.
You've
got
the
attachment
to
axis
and
once
again,
you've
got
the
spacing
of
the
rods
to
be
equal.
A
If
we
get
that
right,
you
can
make
wood
parts,
you
can
make
plastic
parts
here,
the
the
design
initial
design.
It
looks
kind
of
hairy
and
complex,
like
look
at
all
those
parts
and
we've
simplified
it
way
over
that,
like
first,
we
start
with
clam
shells
and
it's
like
all
the
bolts
to
put
clamshells
together.
That's
just
a
pain,
so
you've
got
say
like
the
idler
piece.
A
A
Like
if
you're
on
an
axis
you
might
as
well,
you
don't
really
take
off
one
part:
you
probably
take
off
both
parts
if
you're
modifying
something,
so
that
wasn't
highly
useful,
but
the
number
of
parts
is
remarkably
small.
That's
all
so
concept
is
very
simple.
You
got
a
motor,
you
got
a
rod.
You've
got
some
bolts,
let's
go
through
this,
so
we
understand
this
how
the
system
works,
so
we
still
have
a
motor.
This
is
the
small
ones,
but
we're
going
to
use
larger
ones.
The
ones
we
use
are
nema
26,
nema
224.
A
If
you
look
look
online,
you
can
see
they're
slightly
bigger
than
what
we
use
we're
used
to.
They
have
flanges
for
the
bolt
holes
and
that's
if,
if
we're
gonna
make
that
out
of
wood,
all
you
need
to
do
is
have
a
hole
for
the
shaft
and
the
correct
spacing
for
the
bolt
holes.
Now,
that's
an
industry
standard.
A
A
A
So
yeah
working
doc,
I
mean
we
already-
can
did
some
of
these
new
pieces
already.
This
is
this
is
old,
for
example,
this
is
your.
What
is
that?
That's
your
carriage
carriage
ream
it
out
from
the
middle
faster
print
time.
Do
that
v2
good,
less
print
time,
three
hours,
25
minutes,
0.6,
millimeter
layer,
height,
1.2
nozzles.
So
this
is
in
the
free
cut.
D
I'm
sorry
what
makes
that
you
saw
faster
printing.
I
don't
before
you
said
something
about
the.
A
Key
we
have
1.2
millimeter
nozzles
as
our
standard
that
we
print
with,
because
we
want
to
print
larger
things.
Typically,
the
the
hobby
printers
use
0.4
nozzles,
so
you
get
much
faster
print
rates
which
are
go
as
squared,
so
it
should
be.
In
theory,
you
you'd
be
printing
out
nine
times
as
fast
because
of
the
four
compared
to
0.4
compared
to
1.2
is
three-fold
factor
and
it's
pi
r,
squared
for
the
area
that
you're
depositing
at
one
time.
A
A
If
you're
talking
about
a
full
print,
you
talk
about
a
module,
that's
200
pounds,
that's
what
we
do
plus
the
bed
weight.
It
might
be
another
100
pounds.
How
much
can
these
motors
do?
They
can
do
50
pounds
of
pop.
We
have
200
pounds
out
of
the
box
with
four
motors,
so
that's
a
basic
design.
We
start
with.
E
A
F
A
That's
some
weight,
but
let's,
let's,
let's
get
to
that
in
a
sec
I
mean
you
can
I
mean
so
you
you
want
to
do
reinforced
flat
plates,
so
steel
plates
will
be
quite
warped,
but
you
can
make
it
more
straight
by
welding
on
thin
honeycomb
structure.
On
the
back,
like,
for
example,
on
d3d
genealogy,
we
did
that
where
you
reinforce
it
by
welding
a
pattern
across
so
anytime,
you
have
a
weld.
That's
at
the
right
angle.
You
get
it
super
straight
if
you
clamp
it
down
with
a
flat
bar
lengthwise.
A
A
A
This
was
only
18
inches.
We
have
one.
We
have
a
plate,
that's
three
by
three
feet.
If
we
want
to
go,
4x4
we'd
have
to
cut
that
out
of
the
large
sheet.
We
have.
C
A
Here's
the
points,
so
what
you
do
here
is
when
you,
when
these
are
you
hold
down
these
bars,
which
are
stock
material,
that's
2
by
1
16,
lightweight
stock
that
might
even
be
like
yeah,
that's
1
16
when
you
hold
it
down
really
flat.
That
edge
is
quite
straight
like
to
within,
like
a
millimeter
or
so
so
you'll
have
a
millimeter
flatness
across
the
whole
thing.
A
G
A
Yeah,
you
can
turn
it
down,
but
if
you
get
that
entire
thing,
hot
it'll,
I
mean
a
little
warp
on
you,
so
you
want
to
just
weld
it.
This
style,
where
you
just
got
dots,
that's
plenty
strong
for
what
we
want
to
do.
A
Yeah,
the
reason
for
that
is
to
keep
structural
integrity
and
the
second
one
is
to
insulate
it
so
you're,
using
about
30
percent
less
power
with
an
unheated
chamber.
So
you
took
some
data
and
that
saves
you
about
30
percent
energy
on
a
heat
bed
which,
if
you're
in
production,
that
matters
for
numbers
and
cost
of
electricity.
A
If
you're
running
a
farm,
that's
got.
You
know
a
bunch
of
these
and
running
24
7..
Now,
what's
up
what
are
other
ways
to
do
it?
How
about
tile,
4x4,
tile
or
2x2
tile
super
flat
ceramic
tile
yeah
like
for
flooring,
yeah,
that's
a
good
idea!
So
we
can
put
the
heaters.
C
H
A
Not
insulation,
you,
you
designed
it
so
that
the
heat
dissipates
and
you
got
a
water
water
cooling.
You
have
to
have
water
cooling
in
that
place,
so
we're
gonna
like
this
frame.
It's
gonna
be
our
multi-purpose
prototyping
frame
and
we
can
use
it
for
the
subsequent
cnc
experiments
like,
for
example,
the
mig
head.
We
just
replaced
the
head
and
put
on
a
torch
head
with
that.
A
A
A
We
have
yeah
like
every
eight
inches
to
12
inches,
probably
like
less
than
12,
like
eight
eight
to
nine
is
about
the
right
number,
so
it
doesn't
so
you
have
complete
stability
like
in
terms
of
flatness
and
the
way
those
are
intersecting
they're
just
notched
out
one
into
the
other,
so
they
intersect
like
that.
You
can
grind
them
down
like
that.
That's
the
bet,
but
the
design
is
like
one
of
the
main
design
considerations
would
be
like
how
much
you
got
to
start
thinking.
A
A
On
this
yeah
like
on
that,
we
have
counterweight,
so
we
should
do
counterweight
too.
If
we
have,
if
we
have
200
pound
lift
capacity
and
our
bed
is
under
100,
we
could
do
it,
we
could
just
test
it
without
it
and
then
maybe
add
those
later,
but
we
wouldn't
be
able
to
do
our
full
prints
on
that.
You'd
have
to
add
those
counterweights
later
and
it's
a
pretty
simple
mechanism.
It's
we
would
probably
use
like.
What's
it
called?
A
What's
like
this
tent
wire,
or
what's
it
called
the
that
strong
wire
paracord
power
cord
works?
Well,
you
want
to
have
bearings
around
that
too.
So
the
power
cord
would
would
slide
well,
but
one
of
the
main
limits,
the
design
of
bed
weight.
A
E
C
A
Yeah,
but
that's
so
much
it's
easy,
but
it's
all
time
right
so
in
three
days
four
is
a
good
number.
You
can
go
higher,
but
then
it
becomes
like
so
much
it
gets
kind
of
too
much.
At
that
point
I
mean
four
is
perfectly
workable.
A
E
A
Let's,
let's
go
over
the
the
pieces
and
then
we
so
we
we
are
clear
about
how
this
thing
works.
So
just
studying
the
the
simple
universal
axis
does
it.
We
know
we
have
a
motor.
We
have
a
pulley,
we've
done
it,
you
guys
have
done
it.
You
got
a
set
screw
and
a
pulley.
That's
it.
I
mean
not
much
to
it.
It's
larger,
larger
shank
on
the
motor.
It's
now
I
think,
eight
millimeters.
A
So
here
it's
like
five.
We
go
to
eight
the
bearings.
Now
we
get
go
into
steel,
brass,
bronze,
brass
bushings.
That's
all
mcmaster
car.
A
Like
yeah,
there's
all
kinds
of
all
kinds
of
types,
all
embedded,
sleeve,
bearings,
they're
kind
of
self-lubricated,
that's
what
we
get
you
get
get
them
in
all
kinds
of
sizes
and
one
inch
is
very
common.
So
this
kind
of
a
thing.
Well,
let's
get
a
specific
link
to
this
and
it's
and
it's
only
what
are
we
doing
we're
doing
one
and
a
half
inches
long?
I
believe.
A
No
not
not
like
that.
You
have
different
wall
thicknesses.
So
what
you
want
to
search
for
here
is
inch
and
then
for
shaft
diameter
one
and
then
you
have
different
wall
thickness,
we're
just
using
1
8
wall
thickness,
so
it's
kind
of
thin
one
in
shaft.
So
this
one
we
use
is
one
and
a
quarter
od,
and
it's
this
one.
I
believe
here,
which
is
one
and
a
half
inches
long.
A
A
No
flange
we've
got
a
bunch
of
these
and
that's
that's
industrial
grade.
That's
going
to
be
very
strong,
it's
metal,
so
that's
the
equivalent
of
the
plastic
eight
millimeter!
What's
next!
So
this
is
the
belt
pegs
of
before
now
we
have
the
belt
clamp
and
the
belt
cylinders.
We
need
to
print
new
versions
of
that.
A
So
that's
printing!
So
you
got
your
pulley
this.
Bearing
for
the
belt
we
can
use
now
is
use
the
eight
millimeter
shaft,
which
is
common,
which
we
use
elsewhere,
like
on
the
universal
printer,
use
it
as
a
shaft
for
a
3d
printed
pulley
just
for
the
idler,
so
you
just
gotta
wrap
it
around
so
two
bearings
on
outside
shaft
through
it.
So
if
you're
doing
your
wood
block,
wood
block
two
bearings
shaft
through
3d
printed
piece
to
spin
on
that.
A
No,
we
don't
have
the
time
in
three
days:
we're
gonna
we're
gonna,
okay,
let's
not
do
it,
we,
okay,
so
the
psychology
here
is:
we
got
it's
doable
completely
doable
if
you
wanna,
go
more
industrial
grade
and
have
have
a
print
that
will
be
more
appropriate
for
the
say,
the
mid
mig
welder
printer,
which
just
the
radiation,
would
probably
melt
down
your
parts
after
some,
so
you
got
to
shield
them
so
so
metal
would
make
a
lot
of
sense,
but
like
right
now,
three
days
is
extreme.
A
We
don't
have
time
to
mess
with
stuff,
we'll
be
glad
to
finish
everything
right
and
we've
got
seven
axes
like
eight
feet.
The
rods
are
like
you
carried
the
rods.
How
heavy
is
one
rod,
two
of
those
one
rod?
Almost
one
rod
is
used
for
one
z-axis,
that's
heavy
right,
heavy
stuff.
So
let's
not
no
room
for,
like
anything
outside
of
mission.
Critical,
we'll
use
a
one-inch
rod
right,
yeah
one
inch.
A
A
Those
rods
only
come
like
up
to
6
foot
length,
so
we
can't
do
z
with
it.
I
would
like
to
do
it
because
I
mean
these
rods
are
getting
heavy.
I
mean
talking
about
nine
feet.
Was
it
like
over
100
pounds
just
for
the
rod
I
mean
so
so.
The
the
constraint
on
the
3d
printed
parts
is
just
strong
enough,
so
you
can
hold
the
weight.
A
I
mean
it's
literally
the
weight
now
you're
going
to
have
the
heavy
bed,
but
you
have
four
of
the
z's
and
you
you
kind
of
need
them,
but
that
would
be
the
heavy
part
what
I
would
suggest.
Actually
we,
when
we
build
the
structure,
we
can
hang
the
the
xy
gantry
at
a
comfortable
height
because
actually
like,
if
you
hang
it
up
above
your
head,
that's
actually
not
comfortable.
A
We
should
just
start
start
it
like
at
six
feet,
whatever
we
can
mount
it
higher
later,
because
the
system
will
be
completely
remountable
to
a
higher
position,
but
just
for
a
comfortable
working
height.
Let's,
like
we'll,
build
a
large
frame,
but
let's
work
comfortably,
so
we
don't
have
to
like
go
up
on
ladders
to
actually
mount
the
axes
and
stuff
like
that.
Just
for
ergonomics
and
getting
this
thing
done
because
you
can
easily
hang
it
up
later.
A
In
fact,
it
would
be
good
to
prototype
it
at
a
comfortable
level,
so
we
can
move
it
because
I
mean
we'll
be
messing
around
and
getting
tired
and
stuff
so
doing
that,
okay
equivalent
of
the
so
you
need
four
bolts
for
the
motor.
Now
the
motors
are
flanged
in
this
case.
If
you
go
to
to
this,
so
it's
not,
so
you
can
go
all
the
way
through
the
bolt
length
doesn't
matter,
which
is
a
good
thing,
so
you
can
use
any
kind
of
bolt
length
like
you.
A
Don't
have
to
have
a
very
precise
bolt
length
enough
in
here
in
a
universal
axis.
Those
are
very
precise,
length,
they're,
25,
millimeter
bolts,
because
we're
going
right
through
the
plastic
and
threading
in
so
that's
that,
then
you've
got
three
pieces,
still
the
the
motor
motor
piece,
idler
piece
and
carriage
piece
and
a
belt.
The
belt
is
wider.
It's
15
millimeters
now
so,
instead
of
eight,
what
is
it?
No,
it's
six.
So
six
we've
got
15
but
other
than
that
same
concept.
Just
super
sized.
A
We
did
this,
that's
that's
the
kind
of
topology
we
got
on
a
this
is
this
is
like
not
not
good
enough,
like
the
rods
banned
enough
that
you
can
do
this,
but
very
marginally,
so
you
don't
get
a
good
quality
out
of
this.
You
can
hardly
lift
like
we
could
actually
couldn't
lift
the
bed
properly
like
it
started
skipping
with
a
smaller
motors.
A
Now.
Maybe
if
you
want
to
do
this
and
then
use
heavier
rods,
the
thing
that
started
bending
on
you
was
the
actual
x-axis.
I
mean
four
feet
wide
yeah.
It
just
starts
to
bend
which
does
work
because
of
bed
leveling
that
corrects
it,
the
z,
height
bed
levels.
It
corrects
it
for
you,
but
you
have
to
print
like
just
you
know.
You
won't
get
the
high
performance
of
going
fast
and
stuff
like
that.
H
A
So
in
this
configuration,
this
is
what
we're
doing
this
super
sized
one-inch
rods,
so
four
z-axis
motors
on
top
or
bottom
now,
since
I
would
actually
maybe
mount
them
on
the
bottom,
because
you
got
all
the
wiring
to
go
up
there,
maybe
just
mount
them
right
on
the
bottom,
so
you
have
shorter
wiring.
A
The
universal
controller
is
the
other
part,
but
yeah
think
about
this.
We
actually
have
that
print
surface
there.
We
can
reuse
it.
If
we
like.
That's
it's
three
by
three:
it's
sizeable
that
would
actually
be
a
cool
thing.
I
mean
we
can
go
to
larger
if
we
want,
but
I
mean
I'd,
be
happy
with
getting
this
to
work.
D
To
confirm
when
you
were
talking
about
the
you
know:
weight,
specifications
or
requirements
if
the
each
of
these
molars
is
limited
to
50
pounds,
I
don't
know
how
much
derives
you
know
support,
but
does
that
mean
that
the
part
has
to
be
limited
to
50
pounds,
or
is
there
an
additional
weight
distribution
of
some
sort?
Are
you
always
limited
to
like
with
one
axis
and
one
motor.
A
So
you
got
four
of
them,
so
you're
limited
to
200
pounds
total
lift
ability,
so
you
have
to
use
counter
weights
we're
going
to
use
hollow
rods
for
the
so
the
z
rods
don't
count
because
they're
you're,
not
lifting
the
z
rods
at
all.
Okay,
what
counts
is
the
y
rods
only
and
for
that
we
have
hollow
rod
which
helps
so
that
hollow
rod
may
be,
like
I
don't
know,
maybe
like
30
pounds,
20
pounds,
so
we
still
have
like.
A
If
we
do
a
lightweight
bed
like
this,
we
can
still
get
it
to
work
without
counterbalance
very
likely
because
200
pounds,
that's
considerable,
that
bed
there
it's
it's
about
45
pounds
without
the
reinfor,
the
honeycomb
on
the
back,
but
the
honeycomb
on
the
back
could
be
light.
That
could
be
like
five
pounds
or
ten
pounds
and
we
could
put
something
lightweight
like
like
a
mesh
on
the
bottom
and
that's
full
steel.
A
What
we
want
to
do
is
hold
a
little
bit
of
insulation
and
the
lamps,
so
we
should
use
probably
like
four
lamps,
four
to
eight
lamps.
We
could
use
eight
even
for
two
thousand.
Eight
is
only
two
thousand
watts.
One
thousand
watts
would
be
plenty
to
heat
this
up
because
they
they
actually
work,
really
well
they're,
actually
much
more
efficient
than
other
means,
because
they
are
radiant
as
opposed
to
conductive
heat
transfer,
which
is
faster
and
more
effective.
In
this
case,
not
to.
D
Derail
too
much,
but
in
the
future,
if
you
didn't
want
to
have
a
3d,
I'm
sorry,
a
metal
printing
head.
Is
there
a
way
to
use
you
know
higher
wattage
or
just
multiple
halogen
lamps
to
to
melt
metal
as
well.
C
A
D
E
A
A
That's
well,
you
are
talking
about
laser
lasers,
yes,
definitely
metal,
but
I'm
not
sure
how
much
a
halogen
gets
but
yeah.
I
can't
look
it
up
right
now,
because
yeah
that's
inch.
That
would
be
interesting,
but
I
haven't
heard
of
it.
It
doesn't
mean
it's
not
possible,
but
but
thing
you
have
to
pay
attention
to
is
heat
loss.
A
Maybe
if
you
have
a
very
well
insulated
chamber,
then
you
can
do
it,
but
then
again,
if
the
halogen
goes
to
2000,
when
does
your
glass
melt
in
that
yeah
gonna
melt,
the
glass
before
you
melt,
metal.
A
E
A
Oh
yes,
yeah
a
door
module
is
going
to
be,
or
a
wall
module
they're
around
100
to
200
pounds.
If
you
print
a
full
stack
of
two
by
fours,
you
talk
about
a
ton
or
something
like
that.
If
you
four
by
four
bed
of
two
by
fours,
that's
like
ton,
so
yes,
that
will
be
a
huge
issue.
You
can
do
the
full
bed.
You
can
only
do
a
part
of
it
or
hollow
shapes
because
the
what's
a
cubic
meter
of
plastic
way.
A
Yeah,
that's
the
advantage
of
3d
printing.
If
we
do
the
2x4,
do
it
honeycomb
to
save
material
while
giving
you
the
full
the
strength
that
you
need?
You
can
print
it
full
for
full
strength,
but
with
honeycomb
structures.
No,
you
don't!
You
might
not
need
to.
You.
Can
optimize
for
geometry
for
strength
to
to
dimension
ratios,
so
plastic
is
about
a
gram
per
cubic
centimeter
or
in
other
words,
a
ton
per
cubic
meter.
A
Oh
we've
got
more
than
two
cubic
meters
here.
So
that's
four
thousand
pounds
we
could
print
on
this
bed
we're
talking
serious
stuff
here,
you're,
not
not
going
to
be
able
to
counterweight
that
unless
you
have
an
extremely
precise
counterweight
system.
Now
you
can't
I
mean
the
motors.
Are
you
got
200
pounds
in
the
motors
you
need
to
well
what
you
can
do
is
gear
down,
but
then
the
belts
you
got
to
go
beyond
these
belts.
They're
50
pounds
safe
working
strength
chain,
hey,
have
you
got
experience.
A
Oh
yeah,
look
at
that
yeah,
okay,
so
there
we've
got
a
small
idea,
so
water
tanks
that
get
emptied
and
then
yeah
you
could
possibly
design
this
extremely
well.
You
can
probably
use
these
motors
because
you
got
200
pounds
of
force.
You
only
have
to
have
enough
to
have
a
differential,
of
course,
to
counteract
the
friction
of
your
your
weight.
So
if
you've
got
less
than
200
pounds
of
friction
in
a
system
yeah
you
could
you
could
do
some
kind
of
a
counterbalance
system,
a
more
funky
one.
D
I
don't
know
if
you,
if
you,
google,
a
halogen,
bulb
heat
output.
If
you
get
the
same
thing,
I
do
it'll.
It
answers
the
question
on
the
the
bulb
and
the
glass
and
the
heat
output.
E
A
The
bulb
yeah,
this
is
the
filament,
so
you
have
to
talk
about
how
that
filament?
What's
the
temperature
once
once
the
because
the
radiation
is
omnidirectional,
so
what
is
the
actual
temperature
it's
generating
a
certain
distance
away?
It's
not
going
to
be
that
that
high
so
that'll
be
that
at
the
filament.
A
D
Interestingly,
a
metal
metal
will
have
to
not
melt
to
your
point.
A
So
yeah
the
bulb
is
only
that,
but
that's
not
true,
because
the
radiation
from
the
metal
will
heat
that
bulb
up.
This
is
this
is
a
particular
wavelength
going
out
of
it
once
you
start
heating
it
with
the
radiating
metal,
probably
melt
that
thing
down.
Okay,
but
let's
move
on
so
universal
control
is
what
we
do.
You
don't
have
to
worry
about
it
from
when
we
talk
about
tomorrow,
but
it's
the
same
thing
we've
built.
A
A
It's
internet
speed,
but
external
stepper
drivers
which,
which
you
use
instead
using
the
same
kind
of
control.
We
have
to
worry
about
it
right
now,
we'll
talk
about
it
tomorrow
and
get
to
it
a
structure,
structure
and
axis
today.
So
so
there's
a
lot
there.
So
let's
go
through
what
we
need
between
carpentry
and
and
3d
printing.
So
this
kind
of
thing
we
can,
I
think
we
can
print,
as
is
we
have
to
expand.
Well,
we
have
to
expand
the
bearing
hull.
A
What
I
did
do
right
now,
just
just
before
this
so
on.
We
do
have
some
cat
here.
So
we
have
these
parts
and
here's
some
more
parts
for
practical
purposes.
This
is
a
template.
So
actually
I
drew
this
up
real,
quick
just
before
so
take
a
look
at
this.
This
is
basically
the
spacing
of
if
you
make
it
out
of
wood.
So
basically,
what
I
propose
is
sorry.
We
get
one
team
on
go
ahead.
A
Okay,
that's
that's
the
spacing
for
the
bearings.
So
if
you
so
the
same,
the
center
of
this
is
also
the
spacing
for
sorry
spacing
for
the
well.
We
can
read
the
dimension
off
of
that.
So
let
me
just
read
that
dimension.
So
the
critical
dimension
that
we
have
is
I'm
going
at
3.5
inches
right
now,
I'm
actually
forgetting
about
what
we
did
before.
D
A
A
A
Yeah
yeah,
you
gotta
can't
do
it
out
of
two
buys
really,
but
this
kind
of
makes
sense.
Now
it's
a
little
different
than
what
we
have
in
an
official
cab.
By
can.
A
So
here's
here's
what
we've
got
it's
probably
since
we're
reworking
these
files.
It's
probably
the
easiest.
A
Like,
for
example,
this
this
is,
can
drew
this
up,
we
can
readily
pretty
much
just
redo
this,
because
the
spacing
of
the
the
size
of
the
the
hole
is
not
great,
and
it's
like
some
weird,
like
89.7
millimeters.
A
The
main
thing
is
we
gotta,
like
we
don't
have
this
prototype,
we're
prototyping
and
doing
this,
so
the
simplest
way
to
do
it
is
to
say:
okay,
here's
an
easy,
understandable
dimension
like
I
would
migrate
off
the
current
dimensions
of
89
millimeters,
because
it's
like
it's
going
to
be
a
pain
to
measure
it.
So
we
can
modify
this
very
slightly.
It's
pretty
quick
to
take
a
block,
poke
two
holes
in
it
poke
a
square
and
that's
like
five
minutes.
We
can
redo
that.
A
But
one
of
the
critical
features
of
the
question
is:
what
are
the
critical
features
of
what
we
need
to
design
here
so
that
it's
connectable
to
one
another
and
there's
an
auto
paralleling
mechanism
where
it's
best
looking
on
this
printer
here,
take
a
look
at
what
we've
got
here
to
explain
this,
but
we
want
to
accommodate
that
so
that
anyone
can
build
this
without
high
tolerance
again
once
again
designed
for
tolerancing.
So
what
we
do
here
is,
if
you
observe
the
bearings
on
the
other
side,
it's
called
our
auto
parallel
mechanism.
A
A
A
So
if
we
build
a
frame,
we're
not
going
to
build
a
perfect
frame
down
to
a
you
know,
a
few
thousands
that
you
have
like
zero
bind
up,
we're
designing,
counting
you
can
be
off
by
a
quarter
on
the
frame,
not
a
problem,
even
a
half
inch
one
inch
if
we
have
the
rod
ability
of
the
rod
to
move
in
and
out
as
long
as
this
is
straight,
we
don't
care
what's
happening
on
the
other
side,
the
motion
is
measured
from
the
end
stop,
so
you
still
have
that,
like
it
doesn't
matter
how
far
out
we're
there
on
this
or
if
this
or
this
side
is
not
parallel
to
that.
A
A
Use
use
a
five
foot,
yeah
angle,
quarter
by
four
angle.
Put
it
back
four
by
four
angle:
you
can
lay
out
on
a
table
and
do
this
little
trick.
The
frame
doesn't
have
to
be
perfect,
so
we
want
to
design
that
in
to
our
system.
A
So
that's
part
of
the
design
we
have
to
do
that
means
well
here
it's
an
over
slung
carriage
right.
Okay,
what
we
want
to
do
is
probably
connect
it.
A
We
can
do
this
kind
of
a
system,
but
if
we,
if
we
have
well,
let's
look
at
the
actual
pieces
to
determine
do
you
want
to
go
like
with
the
axis
like
this?
What's
convenient
here
is
that
the
shooter
is
comfortable
to
be
mounted
on
top.
However,
the
extruder
tip
is
not
going
to
reach
over
the
one
inch
carriage,
so
we
have
to
under
slang
the
carriage
it
has
to
be
under
mounted
under
the
actual
axis.
So
that's
the
other
difference.
A
We
have
to
make
a
little
platform
just
connect
this
to
the
underside
of
the
carriage.
A
A
Let's
worry
about
the
zs
and
let's
worry
about
the
y's,
we'll
we'll
solve
how
to
mount
the
x,
because
the
questions
are.
Do
we
go
this
way?
Do
we
go
this
way
because
then
we're
going
to
have
to
put
holes
into
our
pieces
accordingly?
So
the
question
is
what
holes
like?
What
mounting
points
do
we
have
available?
A
A
With
the
little
idler
thing
yeah,
we
can
print
the
pulleys
around
that
go
around
a
the
eight
millimeter
shaft
so
that
the
same
shafts
as
on
the
print,
the
small
printers.
That's
what
we'll
use
for
an
axis
and
two
skate
bearings,
which
are
what
we
use
in
the
extruder
same
thing,
so
mount
those,
and
do
this
now.
The
dimensions
here
are
so
critical
dimensions,
3.5
for
the
centers
and
5.5
to
the
outside,
so
we're
just
within
the
printing
distance
of
the
bed,
which
is
6.
A
A
And
let's
not
worry
about
the
details,
because
we
can
spend
all
day
discussing
how
to
how
to
mount
things
to
this,
because
you
want
the
carriage
pieces
to
be
designed
such
that
you
can
mount
them
this
way
or
that
way
to
each
other
through
the
motor
piece
and
either
piece.
Otherwise,
how
do
you?
How
do
you
do
it?
The
axes
already
have
that
built
in
for
the
516s
like,
for
example,
if
you
go
through
through
these
two
holes,
you
can
attach
well
that
piece
or
the
actual
holes
on
top.
A
You
can
take
this
piece
at
this
angle,
actually
mount
it
through
these
two
holes.
So
it's
already
designed
for
certain
interconnection
mechanisms.
We
have
to
design
this
in
here,
which
is
not
designed,
so
we
don't
have
to
worry
about
it.
Don't
worry
about
it
for
today,
because
for
the
z-axes
at
least,
I
would
say
if
we
get
to
this
man,
if
we
could
finish
the
z-axis
and
the
frame
today,
that
would
be
that'll,
be
a
big
milestone.
A
So,
let's,
let's
perhaps
talk
only
about
that,
then
we
worry
about
the
y-axis,
which
is
also
independent.
It
does
not
need
this
consideration
until
the
the
mounting
consideration
until
we
get
to
the
x-axis,
but
we
know
we
have
a
provision
here
which
is
we
have
bolt
holes,
so
we
can
design
little
bolt
holes
on
the
ends
here.
A
Okay,
anyway,
in
this
picture-
so
I
I
did
this
so
imagine
this
is
longer.
It's
gonna
be
a
little
longer
now.
You
can
also
imagine
if
this
head
holes
at
the
top
at
exactly
the
same
space,
then
you
can
connect
one
to
the
other.
So
that's
the
only
provision
we'll
save
right
now,
we're
gonna
say
once
we
need
to
we'll
put
in
those
well
for
the
wood
pieces
we
can
put
those
in
later
and
for
the
3d
printed
pieces.
A
We'll
put
them
in
too
we'll
see
how
much
we
can
get
printed,
because
we
we
have
we're
competing
between
making
axes
like
cutting
steel,
cutting
rods,
welding
and
actually
doing
some
3d
prints,
but
the
first
thing
on
the
3d
prints.
We
wanted
to
do
like
a
sample
little
test
file
like
this,
so
we
know
that
the
bearing
or
the
rod
fits
in
exactly
we
have
to
fight
it
so
that
we're
going
to
just
get
these
sample
prints
started.
I
got
an
sd
card
on
that,
so
we
can
do
that.
A
A
No
because
I'm
not
sure
how
it
helps,
because
you
can
control
the
size
of
the
things
you're
drilling
in
3d
printing.
What
we're
trying
to
make
up
for
is
the
curve
like
the
width
of
the
filament
thing.
So
when
you
print
a
one
inch
hole,
it's
not
one
inch,
it
might
be
0.95
right,
so
we're
testing
what
exactly
we
need
to
set
to
make
it
more
seamless,
as
opposed
to
like
using
a
heat
gun
for
everything,
so
that
little
bit
of
testing
is
useful.
A
A
I
don't
know
if
we
can
do
that
with
that,
but
we
know
that
we
can
do
the
idler
and
motor
pieces
because
that's
just
one
inch
bits.
We
can
definitely
do
that.
So
maybe
start
on
that
and
for
the
motor.
The
thing
that's
critical
is:
what's
what's
the
bolt
pattern,
so
the
bolt
pattern
yeah,
that's
really
way
way
bought
down
there.
E
E
A
That's
not
see,
so
we
want
to
look
for
exact,
spacing
nema
24
bolt
pattern
I
mean:
do
I
need
to
pull
it
out.
E
A
E
A
Oh
yeah
yeah
just
use
the
motor
as
a
template.
That's
that's
the
best,
but
you
can
also
look
it
up
right
motors
templates.
So
so
it's
important
to
get
the
motor
parts
up
motors
out.
There's
the
pulleys
there's
the
belt
and
what
and
the
rods
once
we
have
that
we
do
it.
So,
let's,
let's
get
into
a
cut
list.
So,
okay,
so
is
this
frame
clear,
so
we're
gonna
use
quarter
by
four
by
four
we're
gonna
make
it
nine
feet
high,
so
we
can
actually
reach
eight
feet
of
print
we're
gonna.
A
Do
it
five
feet
in
fact
six
feet
so
we
can
easily
get
so
here's
another
trick.
I
didn't
mention
about
the
heated
bed.
What
happens
with
a
heated
bed?
Let's
explain
the
concept,
just
a
quick
concept
to.
E
C
E
E
C
A
C
A
A
Oh
yeah
and
the
real
promise
here
is
the
lightweight
honeycomb
structures,
they're,
insulating
and
structural
and
stuff
like
that.
So
but
let's
let's
talk
about
why
we
have
to
have
a
six
foot
frame
for
a
four
foot
bed
and
in
fact,
for
a
heated
chamber
you
can
only
get
like
two
feet
out
of
it
because
you
have
a
closure
on
top.
So
how
does
this
mechanism
work?
It's
a
very
simple
system
that
I
don't
believe
is
patentable.
A
The
way
the
guys
do
it.
They
have
funky
bellows
that
telescope
bellows
bellows
shapes
which
keep
the
heat
in
cool,
but
that
I
think
the
patent
actually
ran
out
on
that
kind
of
technology.
But
it's
also
like
when
I
look
at
it.
That's
not.
A
This
is
better
like
take
a
look
at
what
we've
got
idea
that
is
simpler,
so
high
temperature
heat
enclosure.
You
have
to
picture
this
because
we
don't
have
cat
on
it.
But
okay,
so
it's
your
chamber,
but
what's
the
mechanism.
A
A
A
A
A
A
Nobody
makes
an
open
source
in
the
proprietary
world.
There's
250
000
printers
that
do
this,
but
when
we
do
this
you're
getting
into
the
realm
of
absolutely
multi,
ten
thousand
dollar
printers
at
the
low
low
end
to
quarter
million
dollar
printers
at
the
at
the
regular
end
of
industrial
grade
printers.
But
it's
so
ex.
A
A
A
C
Are
you
saying
this
is
like
a
clash
that
comes
down
over
the
whole
thing
like
or
I'm
not
quite
getting
it's
a
it's
like
is
the
frame
insulated
on
the
sides.
A
That's
your
bed
and
I
have
the
bed
here
on
a
single
because
you
gotta
lift
the
z
through
it.
Okay,
so
that's
gotcha!
That's
what
I
said.
Let's
not
worry
about
how
we
mount
that's
the
x-axis
yep
wait.
Is
that
the
x-axis
yeah?
That's
sorry,
that's
not
the
x-axis,
that's
the
bad
mount
axes,
but
that
here
that's
most
convenient
to
put
them
vertically.
A
A
A
C
A
This
is
large,
so
we'll
figure
that
out
later,
but
I
mean
we
should
think
about
it
now,
but
there
is
a
clear
way
to
get
your
prints
off
and
that
is
you
move
the
print
back
to
the
top
and
pick
it
off.
So
you
fill
your
print
with
an
axe
at
the
end,
there's
a
clear
way
to
do
it
so,
but
okay,
distraction
from
what
we
do
today,
but
the
chamber.
That's
why
I
was
explaining
why
we
need
a
six
by
six
frame,
so
I
will
do
a
six
by
six
frame,
so
we
can
do.
H
A
Okay,
so
that's
that's
this
one
piece
here,
because
because
the
build
procedure
here
is
important
too,
so
it
will
have
two
pieces
like
that,
so
this
is
on
a
table,
so
I'm
going
to
draw
a
little
table.
This
is
going
to
be
our
our
big
table.
The
five
foot
table.
A
So
we'll
you
can
get
nice
corners,
you
can
use
the
table
as
in
your
alignment
point
so
from
the
top.
So
this
is:
how
long
are
we
making
if
we're
going
to
make
this
9
feet
tall
together?
So
we're
going
to
need
to
cut
eight
foot
pieces,
then
the
top
and
bottom
will
add
you
another
four
inch.
A
Okay,
so
where
does
this
angle
on
the
side,
and
so
so
just
think
about
the
construction
of
it,
because
the
build
how
we
build
this,
like
you
know
this
is
large
stuff.
So
what
we
do
what's
going
to
look
like
is
we're
going
to
add
how
we're
going
to
build
this?
Do
we
are
going
to
stand
the
verticals
up
like
that
now
we're
going
to
build
the
long
sides
first,
so
build
the
long
sides,
two
flats,
two
flat
sides,
and
then
we
can
connect
them.
A
With
verticals
right,
two
four,
how
many
pieces
of
metal
do
we
need
if
we
two
four
six
eight
there's
twelve
pieces
of
metal
that
we
need
altogether?
What
I
would
suggest
is
the
following:
four
eight:
this
is
the
suggested
procedure.
Do
the
large
side?
First
yeah!
I
can
hear
you
because
it's
going
to
be
easier
to
square
it
up
later.
So
take
a
look
at
this.
So
so
that's
the
oh
wait.
A
A
A
Slide
duplicates.
This
was
actually
like
welding
this
on
a
table
so
welding
on
a
table.
A
This
is
what
I
was
showing
here:
welding
you're
actually
getting
on
a
table
and
you
lay
these
pieces
on
a
table,
but
you
can
only
lay
this
one's
going
to
hang
off,
because
this
table
is
only
five
feet
wide.
So
you're
gonna
lay
this
one
down
and
we're
gonna
weld
the
other
one
like
this
here.
So
there's
gonna
be
a
gap
there,
because
the
very
difficult
thing
about
angle
is
that
you've
got
you
have
to
make
bevel
cuts,
which
we
have
to
worry
about
because
it
takes
it's
going
to
take
too
long.
A
Yeah,
like
cuts
that,
like
you'd,
have
to
cut
the
angle
at
an
at
an
angle
of
45,
like
all
those
and
like
all
those
it's
like.
A
A
D
I'm
not
sure
if
it's
on
my
side
or
not
does
someone
else
have
their
hmi
laptop
on
his
room.
A
A
F
E
A
A
So
let's
do
a
little
square
like
you
know,
weld
a
square
there,
so
this
is
looking
from
the
top
the
the
edges
are
facing
up.
This
is
laying
flat
on
the
table.
So
if
you
want
to
actually.
A
I
don't
think
I
don't
think
it
would
be
as
good,
but
so
that
so
that's
the
flange
like
here,
that's
the
flange
of
the
iron
you're.
Looking
from
the
top.
A
E
E
A
Yeah,
we
can
do
like
make
them
very
tiny
oversized.
Well,
just
make
them
if
you
do
them
even
like
four
by
four
four
by
four
square,
so
cut
it
out
of
four
by
stock.
That
would
work.
A
A
A
A
A
A
How
many
of
those
eight
foot
fours.
E
F
A
A
That
yeah
12.
it
adds
up.
So
that's
what
we
got
to
do.
Then
we
can
cut
on
the
iron
worker
the
angle
shear.
That
is
perfect,
just
perfect.
Now
what
do
we
do
is
what
exactly
are
we
doing
for
the
little
corners?
So,
let's
make
those
well.
We
should
have
some
quarter
by
four,
if
not
use
like
quarter
by
six
or
something
like
and
it'll
might
trim
out
that
little
that
little
corner
is
not
gonna
matter
too
much.
E
E
E
C
A
C
E
D
A
C
H
You
must,
I
have
power
skills,
but
I
was
actually
looking
at
the
a
little
bit
of
welding.
I
had
some
experience
with
that.
I
was
thinking
about
taking
the
bed.
A
Angle,
that's
quick
on
the
ironworker
that
someone
could
jump
in
there
right
now.
But
after
that,
it's
like,
oh
man,
the
welding
welding
requires
two
people.
If
we
work
on
a
table,
two
people
pretty
much
can
weld
like
opposite
sides.
A
Now
we
don't
have.
We
can
do
it
on
the
floor
too,
and
you
can
have
another
team
of
two
so
four,
but
then
you
have
to
cross
measure
it
because
you
don't
have
the
table
to
align
two
but
anyway,
since
the
table
is
not
big
enough.
Well,
we're
gonna
have
to
cross
measure
it
to
a
line
because
we're
just
tacking
the
corners
first.
A
C
A
Yeah,
if
they
work,
then
would
be
good
now
for
do
we,
we
don't
think
we
have
four
good
masks.
C
A
So
understand
the
thing
about
darkening
like
if
it
does
not
clearly
visibly
darken
to
a
very
comfortable
point.
That
means
the
thing
is
not
working
you
might
like.
If
you
weld
and
it
does
not
darken,
I
mean
it
protects
very
little,
but
that's
not
good
enough
that
you
have
to
have
that
darken
on
you
so
quit.
If
you
see
it
not
darkening
can
a
person
can
any
one
of
you
tell
when
it's
darkened
than
not?
C
D
A
Yeah,
okay,
well,
so
make
sure
that
masks
are
working
and
we
have.
Whoever
does
that
there
could
be
up
to
four
people,
but
a
lot
of
that
could
be
just
layup
and
one
person
welds.
So
it
could
be
still
four
people.
One
is
an
assistant.
Another
one
is
the
welding
guy
beyond
that
so
rods
I
mean
man,
there's
a
3d,
printed,
printing
team,
that's
that
needs
to
happen.
A
So
let's
take
a
look
at
what
we've
got
to
get
on
the
same
page
on
that,
so
here's
the
cad
files.
So
we've
got
these,
but
let's,
let's
migrate
to
3.5,
maybe.
C
I
have
like
a
tiny
bit
more
adjustment
on
like
setting
up
like
that
stuff
on
my
printer
before
it's
gonna
print
properly
like
what
I
just
moved,
something
and
now
it's
not
printing,
quite
right.
E
C
Substantially
by
accident,
I
was
trying
to
reset
the
bed
and
then
it
started
catching
when
it
was
printing
and
not
yeah.
I
don't
know.
A
A
Okay,
let's
take
a
look
at
rod
test
file
with
bushing,
so
let's
print
all
these
things.
So
what
are
these
things?
One
inch
rod
test
with
bushing,
so
this
is
basically
where
you've
got.
A
So
it's
opening
this
one
up.
So
that's
the
one
that
has
the
I
did
0.675,
which
makes
it
1.35.
A
A
A
A
A
What
happened
here
is
that
the
right
one,
oh
yeah,
that's
the
right
one!
No,
oh,
wait!
What's
it?
What's
it
say
yeah,
I
think.
That's!
That's
the
one
if
you
measure
it,
but
it's
labeled
wrong,
but
it's
actually
the
right
one,
so
that
should
be
like
1.1,
so
in
other
words
adding
1
10,
which
is
that
should
get
it
right
to
have
a
rod
fit
what
if
it's
a
little
loose
well
check
this
out.
A
A
That's
your
fix,
the
equivalent
of
a
clamp
bolt
on
the
y-axis
for
the
z-axis.
It
doesn't
matter
it's
held
by
gravity
and
it's
heavy
enough.
It
will
move
anywhere
here
to
if
you
want
to
cap
that
so
the
rod
doesn't
slide
out,
because
if
the,
if
the
carriage
is
moving-
and
this
is
a
carriage
well
sorry,
this
is
this-
is
a
carriage.
So
this
is
this
you're
just
clamping
down
the
bearings
the
bushing,
so
they
don't
don't
fall
out.
A
So
it's
a
it's
a
cap
with
diameters
slightly
larger
than
one
inch
but
smaller
than
1.25
inch.
A
So,
for
what's
more,
that's
idler
for
either
piece
here
we
would
be
actually
closing
off
the
end,
so
the
rod
doesn't
fall
out.
If
you
understand.
D
A
A
Well,
maybe
you
uploaded
the
wrong
file,
but
this
spacing
between
the
holes
should
be
identical
everywhere.
Here,
let's
see.
A
So
I'm
going
to
select
that
point
and
this
point
and
then
it
says:
3.53.
Oh,
very
close,
three
point:
five,
three
inches
three
hundredths
of
an
inch
can
we
we
could
just
print
this
out.
Maybe
do
we
think
yeah
yeah,
it's
only
300s,
whereas
the
oversize
we're
doing
is
0.1.
A
Yeah
so
wants
to
be
the
print
team.
F
E
H
I
have
very
little
experience
with
3d
printing.
I
have
a
bit
of
experience
with
carpentry
and
a
little
bit
of
experience
with
welding,
so
I
can
pretty
much
work
in.
A
Okay,
okay,
maybe
yeah
rest
fast,
so
ken
well,
it
sounds
like
we've
got
a
team,
we're
a
little
sparse.
A
D
All
right,
I
only
got
a
week
left
so
I
mean
what
that
do
to
starting
the
the
3d.
I
mean
the
metal.
G
Like
I
was
happy
to
work
every
every
day,
I
was
here
because
I'm
only
here
for
a
week,
but
you
know
people
here
for
three
months.
B
A
Oh
there's
plenty
of
backlog.
If
you
want
to
do
that
now.
Actually
what
we
do
want
to
do
is
dismantle
the
house
because
that's
not
going
to
get
dismantled.
Otherwise
that's
the
thing
I
would
propose
like
one
of
the
first
things
we
do
because
we're
pretty
much
done
with
that.
As
far
as
what
we
wanted
to
show,
we
have
all
the
modules.
A
So
if
we
wanted
like,
for
example,
outstanding
things
like
siding,
we
can
take,
you
know,
put
up
a
couple
of
modules
and
work
on
the
siding,
but
we
don't
have
to
have
the
whole
house
it's
more
important
to
get
it
out
of
the
rain
right
now,
