A
Recording
started
so
big
concept
here
is
collaborative
design
for
transparent
and
inclusive
inclusive
economy
of
abundance.
That's
our
vision
with
that.
If
you
can
scale
the
process
of
design
to
many
people,
doing
very,
very
small
parts,
that's
power!
How
do
you
do
that
modular
breakdown
and
we
have
certain
techniques
and
the
ability
to
use
freak
out
and
upload
and
download
to
the
wiki
where
you
can
produce
amazing
result
and
we'll
have
a
great
extra
minute
that
can
we
all
together
instead
of
one
one
master
CAD
designer?
A
Can
we
actually
contribute
little
parts
and
components
to
the
universal
axis?
Will
try
exactly
that?
In
a
nutshell,
the
idea
is,
anything
is
made
up
of
primitive
elements.
You've
got
cubes,
sir
Spears
cylinders
of
all
shapes
and
if
you
manipulate
them
and
combine
them
all
together,
you
get
any
kind
of
a
shape.
Now,
there's
also
curves
of
different
kinds
of
curves,
but
with
the
basic
forms
and
what's
known
as
boolean
operations.
A
So
boolean
operations
is
the
idea
that
you're
combining,
adding
or
subtracting
intersecting
cutting,
so
there's
an
ability
within
a
free
CAD
to
execute
a
workflow
where
each
person
is
designing
an
individual
part.
So,
for
example,
you
have
the
universal
axis.
You've
got
the
structure
while
there's
holes
in
there
there's
a
belt.
Oh
there's
motor
holes
there's
a
motor.
Well,
what
would
it
look
like?
The
peach
person
took
one
of
those
and
worried
only
about
one
of
those
and
then
we
throw
that
all
in
a
pot
Stone
Soup
and
make
it
into
a
final
design.
A
So
we're
gonna
explore
exactly
how
that
technique
can
be
enacted
with
a
large
team.
Here
after
we
learn
a
few
basics
about
free
cab.
So
that's
pretty
exciting.
We've
never
done
that.
It's
so
specifically
we'll
use
free
CAD
and
the
ability
to
do
boolean
operations.
So
one
person
designs
one
thing
like,
for
example:
if
it's
a
bolt
hole
pattern
for
the
stepper
motor
that
we
have,
you
will
draw
simply
four
cylinders
of
excellent.
A
They
will
have
to
match
the
bolt
pattern
of
the
motor.
So
that's
the
science
in
there.
It's
like.
Okay,
everything
has
to
match
so
there's
real
numbers
involved.
You
have
a
dimension
now
so
take
the
actual
structure
of
the
universal
axis,
say
motor
piece
and
you
take
those
holes.
Well,
how
can
so
in
a
simplest
example?
How
can
two
people
work
on
that
together?
A
Well,
you
don't
have
to
wait
for
one
person
to
get
finished
with
the
the
body
of
the
motor
piece
and
the
universal
axis
for
the
next
person
to
put
the
holes
on
there.
You
can
just
start
drawing
them
and
then
you
say:
okay,
then
we're
gonna
merge
basically
take
the
two
files,
merge
them
into
one
document
and
simply
subtract.
So
you
get
so
one
person
is
drawing
a
solid
object
which
corresponds
to
the
whole
pattern,
and
then
you
go
body-
holes
and
then
you're
gonna
get
a
body
with
the
without
the
holes.
A
Can
we
use
that
so
so
think
about
that?
How
do
you
break
apart
the
complex
geometry
of
the
universal
axis,
which
does
have
some
complex
attack?
For
example,
the
belt
peg
hole
it's
a
profiled
shape
that
accepts
the
at
the
belt,
so
it
actually
follows
the
contour
of
the
belt
and
it's
you
know,
sloped
a
little
bit
to
accept
the
belt
peg.
Well,
the
part,
that's
key
to
this
modular
breakdown
is
the
breakdown
itself,
how
exactly
these
break
down
an
object
to
understand
its
underlying
parts
so
that
you
can
distribute
that
to
a
large
team.
A
So
this
can
in
principle,
scale
in
an
amazing
way.
So
I
look
forward
to
this
experiment
today
and
then
we
can
do
that
with
many
more
people.
So
say
you
wanted
to
do
not
just
the
motor
piece,
but
then
so
you
got
maybe
like
ten
piece,
ten
parts
on
a
motor
piece.
You
got
another
ten
parts
on
the
carriage
piece
and
ten
on
idler.
Well,
that's
30
people
right
there
just
doing
the
cat
they
could
be
completely
busy.
There
may
be
another
person
doing
the
integration
like
as
soon
as
somebody
has
a
part.
A
They
would
manage
the
team
and
maybe
like
import
that
so
there's
another
person,
so
you
can
come
up
with
a
whole
team
ecology
of
how
you
solve
a
massive
problem
quickly
by
parallel
breakdown,
a
very
powerful
concept
we'll
do
that
for
the
first
time
here,
I,
don't
know
of
anybody.
Who's
done
this
yet
on
this
planet,
I
mean
I,
don't
know
if
anyone's
experimented
with
that
I
haven't
heard
about
it,
because,
typically
the
way
things
work
in
standard
CAD.
A
Now
are
we
still
locking
people
out
because
one
person
is
working
on
a
part,
not
necessarily
because
we
can
have
two
people
work
on
the
bolt
holes
and
maybe
they
can
work
next
to
each
other
and
as
soon
as
they
have
anything,
they
upload
it,
because
people
will
work
at
different
rates.
The
first
person
just
uploads
it
straight
to
the
wiki,
using
the
versioning
system
of
the
wiki.
A
So
so
Matthew
is
mentioning
how
the
coordinate
system
is
very
important
and
scale
is
important.
So
you
have
to
know
all
that.
That's
part
of
interface
design,
but
the
way
we
can
do
that
is
you
select
the
origin
and
make
everything
symmetric
about
the
origin
so
that
when
you're
making
that
say
the
the
rectangular
piece
for
the
body,
the
motor
piece,
3d
printed
piece,
then
that'd
be
around
the
origin.
So
then
the
person
knows
okay,
I
know
the
origin.
Is
there
and
compared
to
the
origin,
say
the
bolt
pattern?
Is
there
it's.
A
And
you're
building
upon
part
libraries
where
some
of
that
language
is
already
pre
designed,
so
you
can
say:
okay.
Well,
we
accept
that
right
now,
if
you
have
an
iteration
shirt
change
it
by
all
means,
if
you've
got
a
better
idea,
you
can't
change
it
and
just
save
it
as
a
different
version
and
noted
okay.
This
has
this
particular
change
and
that
can
live
there.
As
long
as
we
know,
what
part
is
what
we
can
all
do
that
and
if
it's
a
better
design
altogether,
then
we
can
say:
okay.
A
This
is
the
main
version
we're
going
with
we'll
keep
using
that
from
now
on,
but
conflicts
are
pretty
much
resolved
because
it
balls
down
to
who
uses
what,
if,
if
you,
you
think,
you're
a
hotshot
and
you
upload
something-
you
say
this
is
the
best
thing
in
the
world
and
nobody
uses
it.
Well,
maybe
it's
not
the
best
thing
in
the
world,
so
it's
kind
of
a
self-governing
mechanism
where
the
number
of
downloads
and
and
how
a
part
is
remixed
and
reused,
really
determines
who's.
A
The
king
of
the
game
here,
where
we
all
want
to
be
Kings
and
contribute
a
little
bit
to
the
thing,
but
any
of
these
conflicts
about
attribution,
then
I
think
some
are
somewhat
resolved,
simply
the
meritocracy.
This
is
governance
by
meritocracy,
the
best
best
designs
win,
and
then
we
continue
building
upon
them.
So
that's
a
that's
a
good
topic
so
we'll
explore
that
live
today,
just
in
a
little
bit
so
first
I'll
I'd
like
to
go
into
the
lesson
for
today,
which
is
the
design
guide.
I,
believe
it's
lesson
number
seven.
A
So
let's
go
to
design
guide,
OSC
machine
design
going
to
path
generation,
lesson
number
seven!
So
I'll
do
a
quick
survey
of
every
of
the
concepts
and
then
the
tools
that
we
have
available
today,
particularly
in
an
open
source
of
course
that
can
allow
us
to
do
all
that.
So,
let's
start
with
what
is
tool
path
generation
you've
got
a
machine
that
has
some
kind
of
a
tool
head
on
it.
A
You've
got
a
frame
universal
axis,
let's
say,
and
a
tool
of
some
sort,
whether
it's
a
cutter
or
an
additive
manufacturing
thing
like
a
3d
printer,
laser
cutter
or
whatever.
How
do
you
move
that
tool
around?
How
do
you
generate
like
if
you
want
to
cut
out
a
pattern
for
say
your
bolt
mounting
on
a
tractor
whatever
wheel
mounting?
A
Conceptual
yeah
I'll
get
into
that.
So
the
conceptual
idea
there
is
you've
got
physical
motion
and
how
do
you
tell
the
computer,
your
your
Arduino
brain
with
its
Marlin
firmware
or
software?
On
top
of
that?
How
do
you
tell
it
to
do
what
you
do
and
that
is?
It
is
g
code.
It's
g
code
is
the
most
widely
used
numerical
control,
programming
language,
so
g
code
is
basically
commands.
They
look
like
g
1x20
like
numbers.
It's
it's
a
little
simple,
simple
language.
A
It
allows
you
to
say:
okay,
move
here,
go
there
do
a
circle
with
with
that
tool
head,
so
it
covers
motion
as
well
as
turning
other
things
on
and
so
forth.
So
for
whatever
tool
you
have,
you're
gonna
have
corresponding
G
codes
and
various
properties
of
the
G
code
that
that
are
relevant,
like
if
you're
doing,
3d,
printing
you're,
pretty
much
filling
in
a
pattern
and
ops
say
it's
a
solid
object
that
you're
trying
to
3d
print
so
basically
you're
like
zigzagging
back
and
forth
to
deposit
all
the
all
the
material.
A
That's
your
tool
path
for
a
cutter
like
a
like,
say,
a
CNC
torch
table.
You
want
to
cut
out
a
plate
with
a
bolt
pattern.
You
tell
it:
okay
go
to
the
contour
just
go
around.
It
then
turn
off
the
cutting
gas.
Go
to
hell.
Turn
the
gas
on
again
and
cut
out
that
hole.
Then
maybe
stop
the
gas
and
stop
the
flame
and
then
moved
over
to
another
hole
and
so
forth.
So,
basically,
various
commands
that
are
relevant
to
a
particular
tool
head.
A
You
have
to
consider
various
properties
of
that
tool
head
like,
for
example,
if
there's
the
width
of
the
tool
head
and
software
takes
care
of
all
of
that
for
you.
So
let's
talk
about
some
of
the
ways
to
do
that.
So,
typically,
when
I
use
you
can
do
this
manually
or
with
software
so
manually,
you
can
say:
okay
jiwon
like
go
to
X
zero.
A
Zero,
then
go
to
this
place
for
simple
shapes
like
say
a
wheel
plate
on
a
tractor
and
mounting
that
you
can
just
program
that
by
hand
with
this
complex
thing
like
a
3d
printer
book
job
I
mean
that's
many
many
lines
you
like
each
layer
might
have
like
a
thousand
lines.
So
good
luck
doing
that
by
hand.
You
want
to
use
software,
but
you
can
do
it.
If
you
want
to
be
die
hard,
you
can
just
say:
oh
yeah,
I'm
just
gonna
go
there
and
you
just
get
and
like
trace
it
out.
E
A
Plenty
of
it
we'll
get
into
that
there's
tons
of
it,
so
so
general
concepts
here
so
Kurt,
for
example.
If
you
wouldn't
mind
clicking
on
that
curve,
is
the
width
of
the
tool,
so
you've
got
a
cutting
tool
and
when
you,
when
you
cut
with
it
you're
gonna
get
a
particular
curve,
is
right
there
in
the
picture,
the
width
of
a
cut.
A
Offset
so
offset
can
be
like
when
you,
for
example,
on
a
3d
printer
we've
got
the
bed
in
a
certain
location.
We've
got
the
homing
of
the
axes
when
they
go
to
the
end,
stops
that
may
be
one
location,
but
but
you
tell
the
computer
an
offset
which
is
okay.
Well,
the
bed
is
not
oh,
not
with
like
where
you
started
with
your
axe
with
your
zeroing,
but
the
bet
is
off
a
little
bit
so
say:
okay,
go
tan
over
and
and
ten
over
more
to
reach.
A
A
A
So
when
you
turn
something
one
way,
it
will
take
a
little
bit
for
it
to
engage
again
in
the
other
direction,
and
you
have
to
account
for
that
when
you're
doing
your
machining,
that
software,
for
example
in
our
scene
in
CNC
circuit
mill,
we
measured
what
that
is,
and
we
corrected
that
automatically
in
two
paths.
Generator
shavings
are
suare.
Look
at
that
picture,
so
what
our
shavings
are
suare,
it's
it's
all
the
stuff
that
comes
off
when
you're
milling
something
it
could
be
dross
from
a
cutting
of
steel
with
CNC
cutter.
A
Rest
rest
is
another
support,
say
you're
on
a
lathe,
its
rest
literally
like
it
says
you
rest
the
workpiece
on
that.
So
it
can
spin
between
two
centers.
This
is
the
rest
for
a
wood
lathe
in
this
case
rough
and
finish,
cuts
when
you,
when
you
do
milling,
you
might
want
to
do
a
rough
rough
pass
first
and
then
smooth
it
out
with
a
finer
bit.
So
that's
that's
what
it
would
look
like.
A
So
high
speed
vs.
high
torque
machining.
So
if
you
do
high
speed,
if
you
machine
at
very,
very
high
speed,
you're
gonna
need
less
torque
or
you
can
go
to
very
low
speed
with
very
high
torque
like,
for
example,
we
build
the
heavy-duty
drill
press
and
on
that
we
had
a
very
slow
moving
bit
like,
like
maybe
50
rpm
100
rpm,
but
we
can
take
because
it
was
hydraulically
powered.
This
was
enough,
maybe
like
2009
or
something
I
could
cut
one
inch
holes
straight
with
that
through
metal,
those
an
ash
and
the
shavings
were
huge.
A
A
It's
an
idea
that
you
and
there's
efficiencies
involved
with
this,
but
basically
you
have
a
tool
that
goes
not
straight
through
a
cut,
but
it
goes
and
then
kind
of
takes
the
bite.
A
semicircle
moves
forward
a
little
bit
and
that
allows
the
milling
to
happen
with
much
less
force
and
much
more
control
and
less
wear
on
a
tool.
C
A
Because
it's
just
taking
lessons
smaller
cuts,
it's
moving
really
fast,
but
it's
just
taking
small
cuts
while
getting
you
that
large
slit,
because
it's
moving
in
that
pattern
rampant
take
a
look
at
William,
come
back
ramping.
Video
ramping
is
when
you
go
successively
down
into
a
workpiece
and
stuff
just
say
you
want
to
mill
something
you're
starting.
You
know.
You've
got
this
some
solid
object.
You
want
to
mill
it.
You
don't
go
like
straight
into
it
with
all
the
tool
you
might
want
to
start
up
and
take
it
a
little
bit.
A
E
A
You
can
do
that,
so
that's
ramping,
where
you're
just
gradually
going
into
a
workpiece
instead
of
diving
right
into
it,
onion
skinning.
So
when
you're
cutting
things
out
say
out
of
wood,
the
next
onion
skinning
link
when
you're
cutting
out
of
wood-
you
don't
want.
The
piece
is
necessarily
to
fall
out
because
they
might
might
then
like
get
in
a
way
of
the
mill
bit.
So
what
you
do
is
you
cut
almost
all
the
way
through
and
that's
that's
what
it's
showing
there's
a
light.
It
doesn't
really
the
picture
he
doesn't
show
any
of
that.
A
But
basically
you
leave
a
little
onion
skin,
very
thin
slice
at
the
bottom,
so
that
the
piece
of
material
stays
there,
but
you
can
punch
it
out
very
easily
afterwards,
so
that
you
don't
interfere,
you
don't
get
that
jumbled
up
and
getting
loose
and
fly
out
when
the
tool
hits
it
again
or
something
holding
tabs.
That's
the
same
concept
where
you
go
through
all
the
way,
but
lead
little
little
tabs
that
still
hold
the
workpiece
I.
Don't
have
a
picture
that
think
about
going
through
a
cut
out
of
a
circle.
A
A
Two-Sided,
milling
and
registration.
So
if
you're
milling
something's
a
bothersome.
A
You
want
to
turn
it
to
the
side.
Well,
you
have
to
know
where
your
milling
on
the
other
side,
so
you
have
to
have
some
means
of
registering
where
you
are
and
there's
different
ways
to
do
that
nesting
and
material
efficiency
there's
an
open-source
software
called
SVG
nest.
Let's
take
a
look
at
the
demo.
C
F
G
A
You
want
to
save
as
much
material
artificial
intelligence
on
that
can
help.
So
because
you
might
not,
you
know
you
have
to
kind
of
have
to
do
trial
and
error.
If
you
have
like
a
fifty
or
a
hundred
or
a
thousand
pieces,
you
want
to
cut
out,
I
mean
the
human
brain
is
not
really
capable
of
doing
that
efficiently
for
for
very
complex
shapes
that
you
might
not
notice
out
what
the
best
pattern
is.
So
nesting
is
a
an
important
thing.
A
I
mentioned
about
the
frame
nesting
for
the
CNC,
see
know
for
the
3d
printer,
where
we
nest
the
frames
one
inside
the
other
for
material
efficiency.
We
cut
out
first
a
16
inch
frame
out
of
a
four
by
eight
foot
sheet,
so
the
48
by
96
inches
so
take
one
16
inch
frame,
another
one
and
another
one
at
each
four
foot
width.
But
then
we
take
out
the
smaller
pieces
right
from
inside.
So
you
get
60
inch
frames.
A
E
A
Yeah,
that
program
is
flexible
and
there's
other
ones
and
I'll
go
through
all
those.
So
what
is
what
kind
of
machining
number
number
of
dimensions?
Can
you
work
in
to
2.5
3,
&,
4,
plus
axes
are
counted
so
what's
2.5.
What's
2
2
is
when
you're
doing
two-dimensional
cuts
like
CNC
torch
table
and
you're
only
on
the
planes.
Two
point:
five
is
when
you're
in
three
dimensions,
but
you
only
but
you
don't
have.
This
is
an
example,
so
that's
plane
on
a
plane.
A
This
is
2.5
D,
where
you
only
have
you
have
the
full
XY,
but
on
the
Z
you
can
only
go
up
and
down
with
a
tool
head,
so
you
cannot
have
any
overhangs.
So
with
a
3d
printer,
you
can
definitely
do
3d
printed
overhangs,
but
for
machining
you
can't
do
that
if
you
have
like
just
a
three
axis
mill,
it's
moving
like
this
like
that
and
then
up
in
down.
You
cannot
do
over
him.
So
we'd
have
to
have
another
axis
there
unless
you're
doing
3d
printing
also
three-dimensional
mailing
is
Commons,
I
mean.
A
D
A
Go
down
down
four
plus
ax
these,
so
let's
scroll
down
a
bit
to
the
axis
or
you
can
move
in
three
dimensions
and
then
you
can
have
another
axes
like
say
you
put
you
put
a
rotating
axis
on
the
X,
so
safe
with
a
lathe
element
onto
your
you've
got
three
axis
motion.
You
put
a
lathe
chuck
there
that
can
rotate.
A
Well,
that's
your
fourth
axis
and
then
allows
you
to
do
much
more
stuff
or
you
can
put
one
on
the
X
another
one
on
the
Y
n,
even
another
one
on
Z
but
x
and
y
are
comes.
The
five
axis
machining
is
very
common.
You
can
also
do
six
axis,
but
that's
like
not
practical
for
most
things,
not
super
useful
for
the
cost
of
doing
that.
B
B
G
A
Indexing
on
a
sixth
axis
too,
like
you
can
think
about
it
like
when
the
drill
bit
is
spinning.
You
can
spin
it
at
a
controlled
angle,
so
it
acts
like
a
Chuck,
but
that
would
be
like
the
sixth
axis
in
that
case,
essentially
like
three
controllable
indexed
index,
meaning
you
can
control
the
angle
three
lathe
Chuck's
on
each
dimension,
with
the
ability
to
move
those
Chuck's.
That
would
be
six
axis
machining.
A
For
example,
okay,
William
go
next
to
lead
in
and
lead
out
what
is
lead
in
leading
us
how
you
approach
a
workpiece,
so
you
want
to
be
most
strategic
in
how
you
approach
and
work.
We
say
want
to
cut
out
a
square
you
a
square.
That's
that's
the
corner
of
the
square
you
want
to
go
in
lead
in.
You
want
to
go
straight
to
an
edge
and
keep
going
I
mean
that's
convenient.
A
Okay,
so
let's
oh
yeah,
let's
talk
about
so
how
do
you
know?
Let's
say
you've
got
these
concepts
that
you
ready
to
say
generating
your
G
code
for
something?
How
do
you
know
what
you
want?
What
it's
going
to
do?
Well,
you
gotta
be
careful
because
machining
can
be
very
powerful
and
gonna
be
cutting
up
things.
You
don't
want
to
be
cutting,
so
you
want
to
test
it.
A
So
it's
probably
a
good
idea
would
be
to
either
remove
the
the
tools
that
the
cutting
bent
or
remove
the
workpiece
and
just
hit
run
on
that
operation
or
like,
if
it's
say
a
torch
table,
just
make
it
go
without
turning
on
the
gas
or
anything.
So
you
can
test
whether
it's
really
good,
because
once
you
turn
it
on
you're,
destroying
metal
and-
and
you
can't
recover
that.
E
A
A
A
A
B
B
A
You
do
you
can
select
everything
like
the
properties
of
the
tool
has
the
geometry
and
all
that
that's
all
in
there.
So
now,
let's
talk
about
the
open-source
tool
chains
whereby
you
can
generate
the
tool
paths.
So
a
start.
The
beginning
is
called
gerbil
grbl.
So
this
is
a
piece
of
software.
It
allows
you
to
take
to
generate
to
control
any
kind
of
using
an
Arduino
controlling
kind
of
emotion.
So,
basically,
what
was
the
3d
printer
software?
Does
it
uses
gerbils,
as
the
backend
of
is
so?
A
Gerbil
is
basically
the
the
simple
interface
version
of
machine
control
that
you
can
control
directly
through
an
Arduino
and
is
USB
cord
I'd
know
if
that
allows
you
to
have
like
an
SD
card.
Isn't
that
pretty
sure,
but
it's
connecting
an
Arduino
throw
in
the
USB
cord
and
it
says
well,
let's
talk
about
its
Gorman's,
so
often
Arduino
you're,
getting
up
to
30
kilohertz
of
stable
jitter
free
operate
control
pulses.
In
other
words,
you
can
go
like
30,000
times
per
second
in
terms
of
one
can
control
like
30,
you
can
make
30,000
turns
in
one.
A
E
A
B
A
Yeah
I
think
that's
what
it
is:
you're
sending
it
through
a
USB
cord,
which
is
an
alternative
to
the
standard
like
the
old
stuff,
which
is
parallel
ports.
Okay,
so
you
can
on
three
B.
You
can
go
to
the
list.
I
mean
man
there's
so
many
of
them.
So
reddit
is
typically
good
on
getting
you
a
lot
of
good
information,
but
look
at
all
the
cam
and
software's
slicers
software
there's
like
30
40
of
them.
There's
a.
A
There's
3d,
printing
simulations
and
post
processors
machine
controllers,
so
the
list
is
huge
and
then
you
have
to
select
them
as
the
smallest
sub.
That's
useful
for
you
for
us
we're
saying
three
CAD
Marlin
Kira
and
that
gets
you
3d
printing,
milling
all
the
lasers,
everything
else
you
can
use
cute,
Kira
and
Marlin
for
all
that
you
can
use
all
those
other
things
too.
So,
let's
go
through
with
other
tools
that
you
can
use.
You
can
use
Inkscape,
for
example.
What
is
Inkscape
Inkscape
is
an
excellent
professional,
vector,
graphics,
editor.
A
B
B
F
A
On
Inkscape
Inkscape
has
a
G
code
tools
extension,
which
allows
you
to
generate
G
code,
outputs
for
any
kind
of
a
2d
thing.
The
Inkscape
is
in
two
dimensions:
excellent
Inkscape
is
a
common
platform
to
use,
so
click
on
the
click
on
the
g
code
tools,
which
is
the
next
link,
go
back,
G
Co
tools.
So
what
does
that?
Look
like
G,
Co
tools.
A
A
You
can
draw
that
and
then,
with
that
plug-in,
if
you've
drawn
it
and
then
it'll
convert
that,
basically
to
your
your
tool,
path,
which
you
can
export
to
any
G
code
processor
like
cura
like
what
we
do
with
a
3d
printer
software
in
fast,
we
just
put
that
into
that
and
stuff
3d
printing
you're
doing,
for
example,
milling
or
laser
cutting.
It's
beautiful.
E
E
B
A
Generated
the
g-code
kira
activates
that
g-code
and
controls
the
machines
to
do
that,
gqo
tools,
extension
and
then
look
at
freecad
path,
workbench
and
now,
of
course,
freak
adds
my
fav,
because
that
that
has
everything
you
can
write.
An
extension
stood
for
everything
so
you're
drawing
in
precast,
and
out
of
that,
you
can
output
the
actual
tool
paths
for
three-dimensional
operations.
A
G
J
G
A
K
A
K
L
A
G
A
At
libra
cats
libra
cad,
we
use
that
actually
allowed
me
designed
the
freecad,
the
two-dimensional
cutting
files
for
the
brick
press
and
libra
CAD.
Now
that's
a
backwards
way
to
do
it,
because
what
you
want
to
do
is
actually
take.
Take
Oh
freak
out
itself
and
export
dxs
right
out
of
that
freak
Anna
has
that.
So,
if
you
want
to
design
the
three-dimensional
brick
press
and
then
just
take
each
part
and
an
export
a
DXF
of
it,
so
you
don't
have
to
do
any
briquettes.
So
before
we
were
doing
libre
cab
and
freak
out
design.
A
Now
we
want
to
go
freak
ads,
export
the
accepts
so
DXF
s--.
Are
these
two-dimensional
file
formats?
The
accept
is
you
have
to
convert
that
to
g
code?
There's
plenty
of
things
to
do
it
like,
for
example,
the
acceptor
g
code
or
the
Inkscape
generates,
turns
that
into
g
or
e
3
cap
recap
can
input
the
exception
up?
Well,
no
I
missed
that
one
three
pad
you
can
export
like
saps.
Once
you
have
the
DXF,
you
have
to
convert
it
to
zero,
using
a
thing
like
so
yeah,
Inkscape
or
D
accepted
G
code
converter.
A
So
the
accepted
G
code
converter
click
on
that
SourceForge.
That
is
another
fully
open
source
program,
but
no
just
select
one.
What
you
like,
really
the
realistic
options.
There
are
I,
guess
Inkscape,
since
we
use
Inkscape
already
for
other
things,
stay
with
a
tool
that
you
already
know
and
just
add
an
extension
to
it.
But
the
except
the
G
code
also
exists.
It's
an
option.
Next
in
line
is
linuxcnc,
which
is
a
full
machine
controller
and
it
allows
you
to
visualize
the
tool
paths.
The
major
open-source
project
has
been
around
for
a
long
time.
A
The
only
thing
that
I
don't
like
about
it
is
that
you
can't
run
off
your
USB
port.
You
have
to
use
a
parallel
port,
so
that's
kind
of
like
for
our
purposes.
Well,
we'd
have
to
get
another
bunch
of
computers
with
parallel
ports,
which
is
not
super
practical
I.
Think
they've
done
some
work
where
you
can
get
get
go
through
a
USB
connection,
but
it's
more
tricky
I
think
you
have
to
turn
off.
You
have
to
change
your
operating
system,
so
there
is
no
interference
in.
A
D
A
Line
is
hacking,
Marlin
and
Kira
for
2d
tool
pots,
so
click
on
hacking,
Marlin,
so
I
mentioned
that
Marlin
can
be
used
for
two-dimensional
milling
as
well.
So,
instead
of
doing
a
three
dimensional
SDL,
you
input
just
a
flat
file.
So
there's
a
video
right
there
of
exactly
how
to
do
that
and
in
this
example.
A
If
you
click
on
that,
so
this
guy
here,
that's
probing
within
Marlin,
so
you're,
probably
to
get
exactly
the
level
of
the
PCB
that
you're
mailing
in
and
then
you
do
the
milling,
because
you
have
to
be
very
precise
and
if
you
go
too
deep
here
are
two
paths
that
they
could
get
destroyed
or
be
like
to
narrow
or
whatever
it's
too
shallow
or
not
isn't
having
short
circuits.
If
it's
too
deep,
you
might
wear
out
too
much
of
that
circuit.
A
So
that's
fully
done
with
once
again
Kira
and
Marlin
the
same
tool
change
so
completely
doable
and
we'd
like
to
degenerate
to
one
kind
of
a
tool
chain,
so
I'm
sad
about
using
our
custom.
We
do
have
our
custom
milling
software
that
that
Shane
over
lawyers
made
with
the
d3d
C&C
circuit.
No
but
I'd
rather
use
the
same
tool,
change
or
just
happen
yeah,
so
you
have
to
know
less,
which
is
useful,
pakmar
linear
to
the
tool
path.
So
the
tutti
tool
paths
can
be
whatever
is
in
2d
like
laser
cutting.
E
A
One
project
is
kind
of
fizzled
out,
but
just
do
that
maybe
you
know
do
that
report
back.
It
was
documented.
I've
actually
haven't
done
a
community
custom
software,
the
last
time
it
was
a
year
or
two
ago.
So
having
done
that
cool
thing,
yet,
okay,
let's
go
online.
You
can
also
do
this
kind
of
stuff
online
go
to
laser
web
for
lasers
and
mills.
A
That's
pretty
cool
because
it
allows
you
to
take
any
kind
of
a
file.
Oh
yeah
generate
g-code
from
DXF
SVG
bitmap,
JPEG
PNG
sake.
Here's
another
one.
We
were
talking
about
the
acceptor
G
Co
roll
laser.
We're
right
on
the
web.
Gets
you
to
that
so
that
you
can
get
through
the
network
files.
The
lasers
and
CNC
mill
do
a
laser.
You
can
do
this
in
female,
see
who's
on
them,
some
millions
of
them.
Okay!
So
that's
laser
web!
A
So
once
again
you
can
do
that
right
on
an
internet
but,
as
I
said
my
what
we
wanted
to
generate
to
the
generator
isin
go
to
like
one
small
path
that
can
do
anything
and
that's
free
CAD.
You
can
generate
SDL's,
that's
for
three-dimensional
stuff
or
you
can
generate
the
excerpts.
You
can
export.
Well,
if
you
do,
if
you
degenerate
to
the
smallest
tool
chain
and
work
with
STL,
so
say
you
want
to
get
a
two
dimensional
tool
path,
because
frickin
allows
you
to
do
STL
and
Kira
can
import
STL
directly?
A
That's
the
shortest
chain
to
2d
and
3d,
so
we
go
free
cat
and
click
on
free
cat.
Just
tell
you
that
it's
cool
and
you
can
download
it
for
free
your
own
parametric,
modeler
download,
now
I
mean
look
at
the
picture
below
that
you
can
do
all
kinds
of
pretty
good
stuff
with
it
these
days
it's
getting
better
and
better.
So
go
freak
out.
Stl's
go
to
marlin,
so
click
on
marlin,
for
where
this
is
what
we're
talking
about.
A
Marlin
the
open-source
RepRap
driver.
It
says,
and
the
last
time
I
loaded
it
up.
It
said
open
something
like
open
source
control
for
everybody,
open,
whatever
have
changed,
there's
Marlin
and
then
click
on
Keira.
The
particular
branch
of
cure
that
we're
using
is
lulzbot
Keira
because
we
like
lows
but
a
fully
open
source,
Libre
3d
printer
company,
that's
growing
quite
well,
they're
one
of
the
fastest
were
in
company
computer
companies.
They
get
a
lot
of
accolades,
but
you
can
download
Keira
from
Lowell
spot.
We
like
that
more.
The
interface
is
better
on
the
moon.
A
A
Sokurah
for
2d
and
3d,
okay,
now,
let's
keep
going
for
some
more
things,
so
pi
cam,
why
do
I
bring
up
pi
cam,
so
it
generates
G
codes
from
linuxcnc.
Now
here
we're
talking
to
cam,
which
is
computer-aided
manufacturing,
and
this
actually
allows
you
to
show
both
this
is.
This
is
now
above
control,
so
it
shows
you
the
tool
pads.
You
can
simulate
them,
so
it's
a
two
path:
generator
for
three
axis:
machining
it
loads
STL
and
for
2d
models.
So
that's
also
I,
guess
another
alternative
using.
H
E
E
A
It
says
it
generates:
g-code
mm-hmm,
gplv3,
fully
open
source
next
is
I
already
went
through
the
open
source
nesting
software.
So
that's
that's
that
and
just
to
wrap
up
on
on
3d
printing
concepts.
A
People
were
asking:
how
do
you,
how
does
a
hundred
toolpaths
for
a
3d
printer
work?
We
mentioned
already
that
you
can
have
control
over
various
parameters
and
some
of
the
main
ones
you're
concerned
about
is
what
nozzle
size
are
you
using?
So
we
have
to
input
that.
Obviously,
if
you
have
a
large
nozzle,
you
have
to
go
back
and
forth
less
times.
Something
will
be
faster,
faster,
printing.
You
can
control
the
amount
of
infill
from
a
hundred
percent
to
hollow
objects.
Are
you
just
printing
them
out
of
the
outer
edges
of
it
general
workflow?
A
Is
you
generate
your
file
and
or
and
suggested
to
pre
cat?
You
export
the
STL,
you
go
into
kira
and
you
hit
print
now,
so
the
workflow
is
very
simple
and
accessible.
When
you
generate
the
two
paths,
you
want
to
have
a
configuration
file
in
cura,
which
contains
all
the
information
like
I've
got
a
point.
Eight
millimeter
nozzle
or
my
geometry
of
the
bed
is
such-and-such
or
my
printing
temperatures
are
such-and-such.
You
want
to
save
all
that
information,
because
there's
a
bunch
of
parameters
that
you
can
customize
there.
So
that's
a
dot
ini
file.
A
You
can
save
that.
So
you
know,
if
you
have
like
ten
printers
and
they're
all
set
up
differently,
you
can
use
that
configuration
file
for
each
printer
because
you
don't
just
blank
export,
your
GTR
g-code,
you
don't
slice
for,
like
some
generic
case,
you
have
to
slice
based
on
the
physical
reality
of
your
system,
so
you
save
your
your
dot,
ini
files
or,
for
example,
if
we
add
a
heated
enclosure,
then
you
might
do
things
like.
Oh
now,
I
can
go
way
faster,
so
you
could
save
that
configuration.
A
That
shows
the
optimal
speed
at
which
you
can
print
using
that.
So
it's
very
useful
from
the
production
engineering
standpoint,
because
otherwise
you
have
to
figure
all
that
out.
You
have
to
do
a
test
print.
So
that's
the
kind
of
stuff
in
Production
Engineering
that
wants
to
be
shared
because
there's
an
infinite
number
of
variations
that
you
can
have
for
the
kinds
of
printers
and
sizes
of
printers,
and
even
just
say
you
want
to
lay
out
all
the
parts
on
a
3d
printer
bed
for
efficient
printing.
Well,
you
can
have
three-dimensional
nesting.
A
J
A
M
A
You
can
also
what
I'm
talking
about
3d
nesting.
If
you
have
a
limited
size,
then
you
can
do
the
trick
like
we
bent
bend
the
panel
to
do
40,
printing
or
you
can
do
stack
it
vertically
with
little
little.
What
were
they
called
tabs?
We
learned
that
word
put
little
tabs
and
you
can
put
one
object
and
then
print
another
one
on
the
top.
So
you
can
fill
your
entire
8x8
by
in
8-inch
cubic
bed
within
all
the
parts
for
a
3d
printer
in
one
run,
as
opposed
to
doing
it
five
times.
A
So
that's
a
very
powerful
concept.
I
haven't
heard
of
anybody
do
that,
but
it
would
be
great
from
the
production,
engineering
and
marketing
standpoint
when
you're
printing.
The
whole
thing
is
a
cube,
including
a
box
around
it
and
put
a
stamp
on
it
to
ship
it
very
convenient
and
that
that
could
make
a
business.
That's
pretty
robust
if
you're
doing
that,
but
you
have
to
work
out
all
the
details
there
exactly.
A
What
is
the
best
configuration
to
make
it
the
fastest
most
efficient
if
you're
talking
about
economically
significant
production,
otherwise
you're
kind
of
in
a
hobby
realm
and
you're
just
doing
that
for
fun,
maybe
one
time,
but
if
you're,
if
you
want
to
produce
that
for
others,
then
you
care
about
how
much
energy
you
use,
how
much
material
you
use.
So
that's
not
a
not
a
hippie,
not
a
hippie
thing.
No,
it's.
A
A
not
a
crazy
thing,
or
it's
just
all-
that's
that's
not
necessary.
It
is
if
you
want
to
be
ecological
and
and
more
efficient,
which
so
that's,
but
to
get
to
that
that
cubes
pretty
printed
shippable
box,
that's
gonna,
take
some
working
out
and
do
some
trial
and
error.
So
that's
the
value
of
such
a
such
an
initialization
file
or
or
the
actual
STL
file.
That's
got
all
those
pieces
put
together
and
tabbed.
Accordingly,
that's
really
valuable
because
it's
gonna
take
you
a
bit
of
time
to
do
that.
A
So
you
control
nozzle
sizes,
there's
a
very
useful
thing,
called
vase
mode
within
Kira,
where
you
print
just
the
outer
outer
contours,
for
example
like
a
vase
or
a
bottle
where
you're
spiraling
up
continuously.
The
typical
motion
is
you
do
one
layer
and
then
you
jump
up
and
do
the
next
layer
and
vase
mode
you're
doing
spiraling
up
then,
so
you
cannot
really
have
any
openings
in
that
it's
a
solid
thing
with
a
base,
but
very
useful
and
very
fast.
E
A
A
A
Kira
looks
better
than
that
and
I
have
it
on
my
thing.
So,
but
when
you
you
simply
throw
a
file
in
there,
it
appears
I
can
zoom
in
and
then
you
can
hit
save
g-code
or
yeah
like
when
you
hit
save
g
code,
you'll
save
it
to
an
SD
card
on
your
computer,
so
your
computer
has
to
have
an
SD
card
or
you
can
just
take
this
card
and
it
this.
A
If
you're
connected
with
a
USB
port
to
the
computer,
to
the
arduino,
it
will
have
you
print
with
the
live
connection
through
USB,
but
then
you're
taking
up
your
computer.
So
you
want
to
be
typically,
you
want
to
print
out
of
an
SD
card
as
one
way
to
do
it.
So
that's
that's
Kira
I
do
recommend
Lowe's,
but
because
it's
actually
really
cool
like
when
you
pop
it
an
object.
It
kind
of
like
bursts
with
visual
effects.
It
looks
nice
and,
and
it's
actually
way
faster
than
that.
A
It's
optimized
for
or
Ubuntu
and
Debian.
So
here
I've
noticed
what
I
was
using
the
original
here
and
my
computer
would
take
forever
to
slice
things
and
in
aloes
about
Edition.
If
you're,
using,
if
you're
using
Ubuntu
it's
much
faster,
actually
don't
know
if
it's
fast
on
on
the
pcs,
because
I
haven't
used
that.
E
A
Real
ya,
just
running
Ubuntu
installed.
Okay,
so
that's
three.
Some
things
about
3d,
printing
speeds
and
temperatures
are
some
of
the
things
you
want
to
vary
right
now,
we're
printing
at
50.
The
printer
is
capable
of
of
200
millimeters
per
second,
and
that's
like
blazing
fast.
But
that's
where
you
everything
about
your
structure
has
to
be
really
tight
because,
as
I
mentioned
about
the
inertial
effects,
when
you
have
a
motion
in
one
direction
and
rapid
turnaround,
it's
a
huge
inertial
force
in
principle.
You
can
have
a
1
kilogram
object,
produced
1
ton
of
force.
A
A
So
if
your
frame
cannot
handle
you
can
only
print
slow,
but
you
want
to
go
faster
for
better
throughput
and
it's
gonna
take
less
energy
because
you're
heating,
the
bed
for
less
time.
The
bed
is
the
the
main
energy
sink
of
a
3d
printer,
if
you're
using
a
heated
bed,
so
you
do
want
to
print
fast
as
fast
as
you
can.
A
That
does
some
crazy
set
of
operations
say
you
want
to
make
an
extruder
for
the
3d
printer.
You
would
have
a
3-axis
milling
system.
You
definitely
want
to
add
another
rotary
axis,
so
we
can
take
an
object
and
spin
it
and
put
features
in
other
locations
say
you
might
even
have
them
and
you
might
have
multiple
tools
in
the
setup
say
without
tool
change,
even
so
you're,
just
using
just
you
just
spend
$50
for
another
universal
axes.
You
add
it
to
it.
A
So
you're
talking
about
50
to
few
hundred
dollars
per
axis
$50
about
for
a
single
8
millimeter
axis.
Let's
say
you
put
a
bunch
of
those
functions
together
on
a
machine
and
okay.
How
do
I
control
it?
Well,
it's
not
gonna,
be
any
any
software.
That's
gonna!
Allow
you
to
do
that
off
the
shelf.
But
what
can
happen?
Is
you
can
generated
manually?
You
you
understand
you.
A
You
built
your
system
in
such
a
way,
then
that
would
be
a
case
for
for
manual
generation
of
g
code
with
relatively
simple
operations,
for
example,
for
an
extruder
say:
you've
gotta
go
in
and
drill
out
the
hole
so
say
so.
You
will
write
in
the
g
code,
move
this
to
this
location
so
fast
and
then
pull
it
out
and
then
move
this
in
such
a
way
put
this
other
hole
in
there
and
do
that
then.
A
Maybe
spin
spin
that
to
make
like
a
round
part
on
it,
but
you
can
conceptually
get
that
that
you
can
code
that
up.
If
it's
simple
enough,
where
a
lot
of
geometries
like
say
the
you
know
that
extruder
or
other
simple
parts,
I
can
just
program
that
manually,
because
otherwise
good
luck
finding
an
off-the-shelf
solution.
Well,
you
can,
but
that
probably
will
cost
you
thousands
of
dollars
or
and
off-the-shelf
package.
That
does
that.
A
G
G
A
G
A
You
can
do
it
with
metal
on
the
printer
right
now
using
the
printers
we
have,
but
you
can,
if
you
do
taking
a
piece
of
aluminum
or
steel
and
making
any
anything
out
of
that,
and
if
you
make
it
out
of
the
2
inch
universal
axis,
you
can
be
doing
things
like
you
put
it.
You
can
make
a
complete
engine
block
on
that
thing.
So.
A
E
E
A
E
A
What
do
you
do?
A
little
different,
kicad
I
didn't
actually
didn't
mention
kicad,
so
kicad
exports,
the
G
code
trials
for
milling
ki,
see
ad
that's
for
electronic
circuits.
It
has
a
lot
of
the
functionality
where
you
can.
You
have
part
libraries
of
circuit
components
and
all
that
so
there
you're
not
necessarily
using
freak
at
all,
though
you
can
draw
a
circuit
up
in
the
freak
out
if
you
wanted
to,
but
it
will
be
all
manual
job.
E
N
E
A
A
If
you
talk
about
pure,
when
you
talk
about
URL
you
and
have
like,
for
example,
you
do
a
lathe
operation,
you
have
to
generate
that
G
code.
Maybe
it
for
example,
in
free,
can
you
put
that
into
marlin?
All
you
have
to
setup
is
yeah.
You
have
to
match
the
physical
reality.
You
have
to
do
the
settings
within
Marlin
because
you're
at
the
end
of
the
day,
you're
running
stepper
motors,
you
have
the
ability
to
control
five
of
them,
so
you
have
out
of
the
box.
A
You
have
the
capacity
to
do
five
axes
machining
using
Marlin.
Now,
if
you
need
more,
which
typically
don't-
but
if
you
do,
you
would
do
the
external,
like
use
some
more
of
the
pins
on
the
ramps
board
to
generate
the
signals
for
another
stepper
driver,
you
can
add
an
external
another
external
stepper
driver
like
we
talked
about
in
the
controller
session.
Hayden.
M
F
H
A
A
lane
Aden
is
saying
you
can
simply
turn
on.
So
you
got
your
fast
spinning
Chuck
there.
That's
just
a
on
and
off
signal
that
you
execute
through
marlin
after
cura
and
then
the
other
things
could
be
like,
say
other,
like
the
two
posts
might
be
an
X
x-axis,
where
you're
actually
going
into
that
spinning
object
to
get
your
shapes
and
then
you
might
have
the
launch
of
the
lengthwise
axes
where
you're
moving
the
two
bolts.
A
That
way
so
I
mean
it's
it's
up
to
you,
but
you
have
to
define
the
geometry
somewhere
yeah,
which
isn't
it
typically,
you
do
that
in
the
settings
in
Marlin
now,
Marlin
may
not
have
the
custom
solutions
now
for
laving,
but
if
it's
an
open
source
project
so
for
any
programmers,
please
get
us
the
laving
add-on
to
Marlin.
Marlin
already
has
add-ons
for
laser
cutting
and
milling.
A
E
E
A
So
currently
we're
using
Arduino
mega
with
a
ramps
shield.
So
that's
a
standard
most
one
of
the
most
widely
used
for
3d
printers.
The
Marlin
is
interpreting
your
files
and
the
stepper
is
telling
the
stepper
drivers
on
the
ramps
board.
What
to
do
and
those
separate
drivers
could
be
running
your
3d
printer
or
it
could
be
anything
else
depending
on
what
code
you're.
E
A
J
K
D
A
G
J
G
K
A
K
A
You
go
open
up
here,
which
we
showed
you
before
you
put
in
your
three
dimensional
object
and
you
just
click
generate
g-code,
and
then
it
generates
that
for
you
automatically.
So
whatever.
K
A
A
H
A
G
K
D
K
D
K
G
K
K
K
C
A
Man,
that's
what
we're
doing
right
now.
So
right
now
is
the
less
than
we're
in
40
minutes
from
now.
You're
gonna
know
how
to
do
this.
So
let's
start
that
right
now,
thanks
everybody
on
the
remote,
you
can
also
hang
on
to
to
what
we're
doing
right
now.
Cuz
he's
gonna
show
that
right
now
so
open
up
free
cat
who's
got
free
cat
who
has
precast?
Does
everyone
have
prehab?
Okay,
most
out
of
your

Freecad,
I'm
gonna
share
my
screen
for
the
remote
people
share,
so
this
is
it.
This
is
I
mean
the
literacy
and
three-dimensional
drawing
that's
one
of
the
literacies
like
reading
and
writing
click
on
a
new
new
file
in
the
upper
left
corner
and
you
you
get
there
you
go
into
the.
What
freaking
has
is
a
bunch
of
work
benches
under
that
tab
there,
under
the
start,
tab
go
into
the
you
can
go
into
sketcher
or
part
design.

Drugh
me
a
square
there,
you
go,
who's
got
a
square
on
there
their
deal.
The
idea
is
you
draw
shape,
then
you
could
click
close
and
then
you
then
what's
gonna
appear:
click
on
pad
and
you're
going
to
generate
a
three-dimensional
object.
So
now
you
generate
your
first
three-dimensional
object
so
get
to
this
step.
First.

Next
step
so
concept,
this
is
the
most
powerful
concept
in
the
whole
curve
for
CAD,
but
it's
a
very,
very
simple
workflow
which
allows
you
to
do
all
the
parts
that
we
need
to
do
for
the
universal
axis,
and
that
is
you.
Take
your
3d
object
that
you
did
click
on
one
side
of
it
and
the
beauty
of
this
is
when
you
click
on
one
side.
You
select
it,
and
now
you
can
use
that
as
your
new
surface
for.

One
so
practice
the
thing
where
you
have
you
can
during
a
shape
and
then
put
either
feature
either
a
pad
or
or
a
hole
through
a
shape
so
practice
until
you
know
that's
starting
from
the
beginning
screen,
you
should
be
able
to
do
that
in
one
minute.
You
can
get
me
in
shape,
plus
a
cow,
some
kind
of
features
such
as
pad
or
cutout.

So
the
idea
was
to
get
through
this
exercise
the
one
minute
exercise
and
then
go
through
the
workflow.
What
we
discuss
start
designing
the
actual
to
ensure
universal
access,
because
if
you
know
this,
you
can
start,
we
can
divide
the
task
into
all
the
people
and
individuals
swarm
on
the
design
of
the
universal
axis.
So
we
can
do
that
collaboratively.
Does
that
sound
good?
So
maybe
115
for
the
tour,
maybe
like
grab
lunch
or
to.

If
you
can
do
that,
then
you
can
continue
that
process
of
draw
another
feature
and
another
on
different
cases,
a
workflow
that
is
sufficient
to
do
the
design
we
need
on
their
universal
axes,
the
big
one
which
is
going
to
be
an
interesting
experiment,
so
make
sure
you
know
how
to
do
that.
They
practice
that
if
we
don't
do
that
right
now,
but
let's
let's
get
out
the
timer-
and
this
is
a
good
data
point.
So
I
love
it
I'm
gonna
get
a
timer
and
click.

Right
well,
what
I
would
suggest
is
yeah
just
try
to
get
this
work
flow,
so
you
really
know
it
because
it's
then
you,
then
that
means
you
really
understand
the
whole.
It's
really
about
the
menus,
like
the
okay's
and
click
finish.
What
you're
selecting
a
treeview
versus
the
task
view
and.
D
H
A
So,
let's
move
on
right
to
the
exercise.
For
that
please
go
to
a
document
which
is
I'm
going
to
start
this
right
now,
let's
go
to
the
universal
access
page
on
the
wiki
for
people
that
have
a
computer
universal
universal
access,
2
inch
universal
axis,
it's
linked
from
the
universal
access
page,
okay!
So
and
we
will
start
in
a
document
where
we
get
very
clear
about
what
all
the
elements
are,
because
without
that
kind
of
clarity
will
be
designing
things
that
will
not
fit
together.
So
we
need
to.
We
need
to
start
with
that.
