A
Okay,
well,
let's,
let's
see
where
we
are
on
the
last
few
weeks
of
the
schedule,
so
I
mean
last
week
we've
been
working
on
the
shred,
not
shredder,
but
torch
table,
plus
the
filamentor
and
the
winder
and
pooler,
and
the
status
of
that
is
is
what
we're
still
trying
to
get.
D
Looking
better
than
ever,
I
mean
we
had.
We
had
two
mishaps
during
the
construction
or
the
running
of
it,
where
the
filament
melts
in
too
high
of
a
temperature
and
it
it
carbonizes,
and
it
forces
us
to
clean
it
up.
So
now
it's
clean
as
a
whistle
ready
for
you
know,
run
number
three
or
four.
D
We
have
west's
magical
algorithm,
keeping
the
temperature
in
check
which
actually
works
much
better
than
the
controllers
we
used
before,
which
I
think
they
kind
of
caused
the
first
carbonization,
the
first
clogging
and
I've
cleaned
it
up,
embedded
thermometers
closer
to
the
pipes
and,
I
think
yeah.
What
I
have
to
do
is
just
reattach
the
auger
everything's
in
place.
D
We
gotta
try
to
dry
out
the
plastic
in
the
oven,
let
it
sit
in
100,
fahrenheit
or
whatever
in
30
40
minutes,
and
then
do
a
run
with
that,
because
we
can
get
filament
coming
out
of
it,
but
it
obviously
has
water
bubbles
or
some
sort
of
aberrations
in
the
plastic.
D
So
yeah
we're
doing
we're,
doing
a
new
run
and
see
what
we
get
basically,
but
I
would
say
everything
is
having
done
several
try
runs.
I
think
this
this
setup
might
just
do
the
joke.
A
Those
were
for
thrust
like
they
were.
There
was
a
little
holder
where
the
shaft
was
prevented
from
going
up
or
down,
because
when
you're
drilling
into
the
plastic
it
actually
pushes
it
up
into
the
into
the
motor.
Quite
quite
a
bit
of
force
like
with
all
the
reactive
force
of
all
the
torque,
but
right
now
so
the
the
shaft
is
just
lodged
in
and
that's
that's
all.
We
have,
if
there's
any
upward
force,
that
the
shaft
of
the
motor
is
taking
up.
All
that
force,
which
is
so
far,
has
been
working
so
yeah.
D
A
A
A
D
I
mean
technically,
they
are
working
running
it
last
time
with
a
very
varying
width.
Filament
didn't
really
trigger
it.
On
and
off
now
we
have
attached
a
fan
right
underneath
the
extruder,
which
means
that
the
instant
plastic
will
firm
up
instead
of
varying
and
with
the
weight
cooling
down
on
it.
So
I
hope,
with
the
the
thicker
filament
coming
out
through
the
auger,
pushing
it
out
and
also
the
fan
cooling
it
I'm
hoping
to
do
around
with
that
and
see
how
it
acts.
D
A
All
right,
okay,
so
according
to
the
schedule,
so
cnc
torch
and
shredder
for
this
week,
so
we've
got
the
now
we're
in
november
first
through
the
fifth
week
week
of
so
we're
ready
to
start
working
on
the
shredder.
The
cnc
torch
we're
kind
of
wrapping
up,
but
we
pretty
much
redid
all
the
axes
so
that,
let's
see,
let's
look
at
some
pictures,
but
the
system
that
we
have
right
now
is
smooth
in
motion
and
took
some
data
on
the
actual.
A
Starting
on
cable
chain
pieces,
but
here
took
some
data
points
on
the
amount
of
force.
So
right
now
we
have
like
25
pounds
of
force
on
each
axis
about
it's
actually
between
15
and
30,
depending
on
which
axis
and
which
direction
you're
pulling
if
you're
pulling
where
there's
like.
It's
not
isotropic
in
the
sense
that
you
have
less
force
in
one
direction
than
the
other,
simply
because
in
one
direction,
you've
got
all
the
belt
to
pull
through
and
the
belt
stretches
just
a
bit.
A
So
the
force
could
be
different
like
it's.
You
know
between,
say,
15
and
20
or
like
20
and
30.
On
the
other
side.
As
far
as
how
much
force
we
have
and
this
one
side,
the
first
side
y1
here,
let's
see,
what's
the
what's
the
measurement
right
there?
A
Separate
motors,
so
there's
two
things:
two
things
we
did
so
one
one
thing
is,
is
pulling
getting
a
few
data
points,
so
we
were
interested
in
backlash
actually
calculating
backlash.
We
were
interested
in
calcul
or
just
measuring
the
belt
tension
like
how.
How
do
we
know
that
the
belt
tension
is
uniform,
so
you
can
actually
compare
and
tell
somebody
to
do
it
such
and
such
tight,
and
the
third
thing
was
just
the
amount
of
push
force
and
pull
force
on
axes.
So
here
actually
looks
like
I'm
pulling
on
the
belt
itself.
A
A
It
was
like
12
to
15
pounds,
in
other
words,
in
order
to
deflect
the
belt
that
much
it
had
12
to
15
pounds
of
force
required.
So
I
mean
you
can't
really
translate
to
oh,
what
exactly
is
the
pulling
force
on
the
belt,
but
you
can
get
an
idea
that
if
you
get
that
measurement,
you
know
you've
done
it
consistently.
So
say
on
this
side
and
the
other
side,
and
both
sides
were
around
that
15
15
pound
marks,
so
we
can
say:
okay.
This
is
a
consistent
measurement
that
we're
getting
throughout
the
whole
system.
A
A
Some
more-
and
this
was
actually
backlash
I'll-
get
back
to
that
so
on
this
part
here.
So
I
put
all
these
welding
wire
strings,
but
I
just
hung
a
wire
attached
it
to
the
the
carriage
here
and
then
moved
it
using
the
controller.
So
here's
the
system-
you
just
wind
the
wire
through
well
here
th
this
one
here-
is
measuring
the
actual
belt
tension.
I
was
pulling
on
that
and
here
we're
pulling
on
actual
carriage
to
see
the
the
amount
of
force.
A
That's
the
detail.
This
system
works
pretty
well,
there's
you
tension
it
by
screwing
down
the
the
screw
and
then
tightening
on
the
back
with
a
bolt.
So
that's
good,
but
the
idea
there
was
measuring,
like
yeah
between
15
and
actually
30
pounds
of
force
on
one
side
where
say
the
motor
is,
on
the
left,
hand,
side
and
you're
pulling
against
this
side,
meaning
moving
left
leftwards
here,
you're
pulling
on,
because
the
motor
is
on
our
left
hand,
side
here
in
this
picture.
A
If
you're
pulling
on
the
motor
to
the
left
in
this
picture,
that
means
the
amount
of
belt
that's
pulling
is
just
that
length
between
the
motor
and
the
carriage,
so
that
force
would
be
a
little
stronger,
whereas,
if
you're
trying
to
pull
the
other
way,
where
you're
trying
to
pull
through
the
whole
belt
across
the
machine
where
it's
got
more
like
two
meters
of
length
than
oppose
opposed
to
like.
A
Yeah,
it's
just
a
little
less
force
because
the
belt
stretches
slightly
and
you
can
see
it
actually
when,
when
I
pull
down
on
the
belt
like
by
hand
next
to
the
carriage,
you
can
see
between
1
to
1.5
millimeters
of
the
belt.
A
Actually,
the
the
shaft
of
the
motor
stepper
motor
spinning,
I
took
a
just
took
a
a
measurement
to
that,
in
other
words,
you're
stretching
the
belt.
What's
that
mean
the
belt
is
moving
along
the
direction
of
the
belt
and
what
that
means,
if
that's
the
case,
the
little
pulley
you
can
actually
see
it
spin,
a
visible
amount
of
degrees
and
just
measuring
it
was
between
like
1
and
1.5
millimeters,
just
using
a
simple
millimeter
ruler
and.
A
A
It
does
tension
it
and
to
the
effect
of
a
belt
stretch
of
you
can
say,
because
we're
pulling
across
the
whole
system
and
how
long
is
the
whole
system.
It's
like
four
feet
twice
so
like
eight
feet,
almost
three
meters
when
you
pull
it
you're
getting
an
overall
one
to
one
point:
five
millimeters
of
belt
stretch
across
the
system.
A
So
that's
that's
a
real
figure.
What
does
that
mean
for
backlash
backlash
is
an
accurate
inaccuracy
of
reversing
direction
because
you
got
things
like
like
belt
stretch
and
other
inaccuracies,
like
bearings,
maybe
force
against
bearings
and
stuff,
like
that.
That
means
that,
well,
if
you,
for
example,
if
you're
traveling
fast
and
you're
like
you
know,
moving
back
and
forth
yeah,
you
could
get
that
stretch
of
1.5
millimeters
if
you're
going
very
slow
and
the
belt
tension
is
at
a
certain
value.
A
So
when
you
move
it,
it
tends
to
stretch
less
so
you
want
this
interplay
of
as
tight
as
possible
for
belt
tension,
but
not
so
tight
that
you're
putting
so
much
resistance
around
the
bearings
of
the
shaft
that
it's
just
hard
to
move.
So
this
value
of,
like
10
to
15
pounds,
was
pretty
good
to
still
get,
as
we
noted
like
15
to
30
pounds
of
actual
force
that
each
axis
is
moving.
A
That's
each
axis
so
we're
getting
like
like
35
to
like
45
or
so
or
50
30,
plus
50
yeah,
like
30
to
50
pounds
of
force
that
you
we've
got
for
motions
that
should
be
robust,
that,
whatever
we're
doing
with
a
torch
table,
you
don't
have
any
any
stoppage
by
some
friction
or
whatever.
So
it's
good
good
strength
like
it's
actually
hard
to
when
you're
actually
moving
it.
It's
pretty
hard
to
stop
it.
A
It's
got
quite
a
bit
of
force,
that's
good,
and
then
we
did
this
backlash
measurement
and
just
to
go
with
that.
So
a
dial
indicator
put
it
on.
So
that's
the
carriage
put
a
little
piece
of
pipe
strap
and
bent
it
around
so
that
the
dial
indicator
would
touch
it,
and
then
we
moved
it
by
one
millimeter
or
so,
or
10
millimeters,
and
we
looked
at
the
dial
gauge
there.
So
the
gauge
one
big
revolution
of
that
is
0.1
inch
on
this
dial
indicator
and
we're
observing
the
values.
A
Whenever
we
would
move
it
forward
and
backwards,
we
would
get
the
according
amounts
and
the
difference
between
the
amount.
You
move
one
direction
and
okay
say
you
do
two
directions
consecutively
in
the
same
direction:
it
gets
you
like:
okay,
here's,
the
distance,
you're
moving
per
step
and
we
were
getting
values
like
in
the
actual
system.
A
When
you
turn
the
knob,
we
were
moving
by
0.1
inch
on
the
one
millimeter
setting.
So
you
do
that
now.
If
you
try
to
move
it,
0.1
millimeter,
you
can
move
it.
You
would
see
like
10
10
divisions,
which
means
10
thousandths
motion
every
every
time.
We
stepped
it,
but
that's
why
you
started
to
to
get
backlash
visibly
where
you
move
it
in
one
direction
and
then
you
move
it
the
other
direction
and
dial
would
not
move.
A
That
means
you
when
you
try
to
move
it
back
like
you,
took
out
all
the
stretch
and
accuracy
and
then
on
a
second
or
third
one.
It
would
go
move
back
to
that
10
000
motion
after
like
stretching
out
the
belt.
This
was
on
a
0.1
millimeter
setting
and
you
can
notice
that,
like
that's,
not
point,
one
millimeters
like
ten
thousands
is
not
point
one
millimeter
because
point
one
millimeter.
A
Is
actually
that's
a
hundred
thousandths?
No,
that's
a
hundred
sorry
hundred
microns.
So
anyway,
there's
there's
a
conversion
factor
between
like
what
we're
actually
seeing
on
the
dial
and
what
you're
turning
on
on
an
lcd
controller.
So
the
lcd
controller
does
not
move
in
like
when
it
says
you're
moving,
0.1,
millimeter
or
10
millimeters.
A
It's
not
really
doing
it.
It's
like
it's
moving
in
gradations
of
like
point
like
it's
not
like
point
one.
It
would
be
like
point
three
so
anyway,
like
there's
a
there's,
a
calibration
issue
between
like
what
you're
actually
trying
to
dial
the
controller
and
what
you
see
in
the
real
motion
just
details
here,
but
all
said
and
done.
We
were
getting
on
the
one
side.
A
We
were
getting
actually
10
micron
backlash,
whereas
on
the
other
side
we
were
getting
no,
not
10
micron,
it
was
10
10
000
on
the
dial
it
was
here
is
the
dial
shows
like
zero
to
a
hundred
zero
to
ninety
or
zero
to
a
hundred.
Each
gradation
is
one
thousand.
We
are
getting
ten
thousands
of
of
backlash
on
one
side
and
we
were
getting
about
forty
thousandths
on
the
other
side.
A
That's
quite
good.
That's
all
right!
I
mean
40.
000
is
what
it's
like.
What
is
that,
in
terms
of
we
were
we're
going
like
in
a
general
torch
table
accuracy
that
we're
going
for
like
1
16
or
like
1
8
1
16
more,
like
you
want
your
features
that
you
want
to
cut
to
be
pretty
tiny.
So
so
in
the
40
micron
backlash
you
get,
I
mean
that's
less
than
132nd.
I
mean
what
do
you
get?
40,
sorry,
40,
thousandths
40
divided
by
a
thousand,
I
mean
that's
0.04,
that's
about
one.
A
D
About
that
our
firmware
since
we
changed
pulleys.
D
E
A
Here,
we're
able
to
measure
like
here
we're
observing
that
okay,
yes,
we're
actually
getting
this
10
000
motion,
but
on
the
controller
it
doesn't
say,
10
000,
because
there's
calibration
factors
for
the
size
of
the
pulley
and
all
that
kind
of
stuff
which
we
haven't
considered.
But
the
actual
physical
motion
is
your
ten
to
forty
thousandths
of
an
inch.
So
that's
that's.
Where
are
on
that,
and
all
the
axes
are
moving
right
along.
We
we've
made
more
of
these
carriages
and
where
can
where?
Are
we
exactly
on
that
right?.
F
A
A
The
x
is
being
carried
by
the
y,
so
we
want
to
be
as
light
as
possible
for
inertial
effects.
You
want
the
motors
to
have
as
much
strength
and
not
not
counteract
so
much
weight
itself,
because
weight
would
be
friction
against
the
bushings
against
the
shafts.
We
mentioned.
Something
like
friction
of,
of
bronze
on
steel
is
like
0.1
up
to
0.3
or
so
so.
A
Any
weight
that
you
have
on
a
system
translates
to
friction
force
that
you
have
to
overcome,
and
our
overall
system
weight
here
would
be
like
50
or
so
50
70
pounds
for
the
the
x
and
z
axis
total.
It
gets
pretty
heavy,
so
you
want
to
minimize
that
weight,
and
so
we
use
the
hollow
shafts
using
the
other
bushings
that
we
had.
We
had
some
other
nylon
bushings
that
we
put
into
the
carriages
here.
A
So
that's
where
we
are
so
now
on
on
a
shredder.
What's
up
with
that,
so
that
I
would
suggest
that
maybe
we
maybe
get
a
team
going
on
a
shredder
continue
on
a
torch.
The
next
steps
on
the
torch
are
to
look
at.
How
do
you
generate
the
code
and
I
think,
there's
a
very
simple
way
to
use
marlins
like
say
we
have
the
blades
to
cut
out.
You
can
do
you
can
hack
it
by
going
into
actually
just
use
cura,
so
you
got
your
three
dimensional
stl
and
then
here's
one
one
hack.
A
You
can
go
into
zero
infill.
Well,
what
does
that
do?
That
means
it
has
no
insides.
It
will
only
be
doing
the
external,
the
external
contour.
So
so,
if
you
wanna
easy
way
to
generate
cut
files,
okay
take
let's,
let's
say:
let's
actually
show
that,
because
it's
pretty
useful
to
do
this
so
say:
shredder,
let's
see,
can
we
find
shredder.
A
Because
I
mean
we're
close
to
that,
we're
close
to
actually
running
some
test
fast,
so
first
just
run
the
torch,
no
torch
on
just
see.
If
it
moves
like,
we
think
it
wants
to
move,
we
have
to
get
calibrated
towards
the
different
pulleys
that
we
have,
so
that
would
be
actually
in
the
firmware
in
marlin.
We
have
to
set
the
actually,
we
don't
need
to
modify
the
we
can
do
that
in
start
and
then
g
code,
you
can
actually
set
the
steps
per
millimeter
in
a
start
g
code.
B
Okay,
yeah:
let's,
let's,
let's
take
a
look
at
it:
we've
got
that
right.
There.
A
B
Here:
okay,
let's
do
this
one.
B
A
A
Well,
it's
got
those
various
features,
but
the
red,
oh,
so
it's
actually
got
shell
thickness
of
2.4.
So
if
we
hack
it
further,
let's
go
1.2
and
you
should
get
a
single
line
because
we've
got
1.2
millimeter
nozzle
size,
shell,
thickness
of
1.2.
That
means
you
should
get.
This
is
the
actual
contour
you
want
to
cut
out.
So
what?
A
C
A
Well
it
what
it's
doing
is
the
bed
leveling
correction,
but
that's
a
post-processing
step.
The
g-code
here
is
plain,
but
upon
startup
you
have
the
calibration
of
the
bed
level
after
which
it
actually
modifies
all
the
code.
So
it's
no
longer
doing
this,
but
right
here
this
is
like
the
raw
format.
That's
just
a
plane
without
z
jumps.
A
So
this
should
work
and
we
should
test
it
because
we're
still
going
to
use
the
z
level
correction,
we're
going
to
have
the
probe
and
we're
going
to
do
the
level
the
bed
thing.
So
it
gets
you
approximately
to
well.
It
will
follow
like
if
you
know
if
your
piece
of
metal
is
slanted,
it
will
just
follow
it
at
the
right
level,
so
it
will
still
be
doing
that.
But
the
underlying
cut
will
be
your
your
plain
flat
shape,
plus
that
adjustment
that
it
pulse
processes
into
the
code.
A
But
let's
see
so
g1,
let's
see,
let's,
let's
go
down
like
halfway
through
which
we
know
that's
like
that's,
probably
where
we
want
to
be
late.
Okay,
actually
it
says
layer,
16,
okay,
we'll
go
to
layer
16.
A
It
says
g1
feed
rates,
e
e.
I
think,
what's
that's
extruder
now
it
goes
to
feed
rates
x
y
z.
So
it
moved
up
this
step
right
here,
z.
Now
it
goes
to
outer
wall.
It
actually
tells
you
so
it's
actually
annotated.
So
you
got
feed
rate
of
2400
it.
Okay,
it
moved
up
again.
A
A
That's
going
to
be
all
the
stuff
that
you
want.
That's
going
to
be
the
outer
perimeter,
so
there
you
go,
you
got
that
copy
it
and
then
what
else
we
got
and
probably
so
it
did
probably
like
the
whatever
the
other
features
are.
That
was
the
wall,
that's
probably
like,
maybe
like
the
inner
part
or
the
holes
that
are
in
there.
But
it'll
probably
go
like
this
and
as
you
notice,
it's
like
it's
got
x
and
y's,
no
z's!
That's
that's
cool!
A
It's
still
at
that
same
layer
and
note
that's
also
without
the
the
bed
leveling
correction,
which
is
not
in
the
source
code
here.
So
so,
then
you
keep
going
keep
going
and
I
would
expect
to
go
until
I
see
layer
17
there.
So
all
that
is
what
you
need
now,
the
other
things
like
the
different
feed
rates.
We
probably
don't
just
cut
those
lines
out.
A
It
might
be
like
a
different
feed
rate
for
the
internal
features
versus
the
outside.
Here,
we're
just
cutting
all
at
the
at
the
same
rate:
f
3000,
that's
the
feed
rate
part,
so
we
just
set
the
feed
rate
initially
and
so
basically
like
all
these,
these
ones
with
the
g1
x
and
y
series,
we
just
copy
that
and
that's
that's
our
g
code
for
the
actual
geometry
and
that's
kind
of
a
hacked
way
to
do
it.
A
But
if
we
have
the
blade,
I
mean
it's
a
simple,
relatively
simple
thing:
like
all
the
layers
like
say:
we
have
an
extruded,
you
know
half
inch
blade,
you
know
slice
it
down
the
middle,
just
take
all
all
of
a
single
layer
and
basically
cut
out
those
other
feed
rate
changes
and
and
the
e
parts,
because
e
is
extrusion.
A
Oh,
in
fact,
yeah
since
e
is
not
going
to
be
connected.
So
what's
going
to
happen
there,
it's
going
to
think
it's
got
the
extruder,
but
it
does
that's
e
right,
it's
not
connected,
so
it
will
just
be
making
believe
it's
doing
that
it'll
be
sending
those
steps
to
the
stepper
motor
yeah.
So
if
you
look
at
the
detail
there,
it's
g1
x
something
y,
something
e.
So
it's
got
an
e
line.
We
can
just
leave
the
e
line
because
that
won't
be
doing
anything
since
the
extruder
is
not
connected,
so
we
can
hack
it.
A
That's
like
the
simplest
way,
in
my
view
like
then
otherwise
I
mean.
Of
course
we
can
do
it.
There's
d
accepted
g
code
converters,
there's
free
code,
free
cad
generation
of
of
cut
files,
little
learning
curves,
but
here
we
have
this.
We
just
pull
out.
You
know
basically
one
layer
line
from
the
code
in
in
the
cura
and
that's
that's
it.
So
that's
one
way
to
do
it.
A
Test
would
be
manual.
Second,
test
is
like
here,
you
would
do
you
can
do
the
d9,
which
is
the
plane
available.
So
there's
one
that's
plane
available.
The
easiest
way
to
control
it
is
you've,
got
start
okay,
so
we.
What
do
we
do
step
by
step,
we're
ready
to
test
this?
We
just
run
this
no
gas,
because
you
only
be
burning
stuff,
be
you
know
before
you're,
hot
you're,
just
testing
everything
make
sure
you
got
the
correct.
We
did
all
the
manual.
C
A
Yeah
yeah
yeah,
that's
that's
all
we
gotta
we
gotta
test
all
that
with
the
new
system,
so
basically
yeah,
so
so
manual
testing
just
run
it
physically.
So
you
know
you
got
the
right
motion.
You
know
that
you
have
the
the
bad
bad
leveling
on
one
side,
zeroing
the
axis,
so
you
zero
the
x
and
y
you
zero,
the
z
do
the
bed
leveling.
Then
you
watch
it
to
make
sure
it
goes
to
the
right
place.
A
Make
sure
that
you
can
actually
get
it
to
the
right
place
in
the
coordinate
system
that
we're
using
probably
convenient
for
us
would
be
if
we're
cutting
it
out
of
eight
inch,
wide
half
inch.
Steel
just
lay
the
steel
bar
across
and
do
like,
maybe
like
three
or
four
blades
at
a
time,
because
that's
four,
four
or
so
blades
at
a
time,
because
that's
how
much
fits
across
the
bed
or
no,
actually
I
mean
we
could
we
could
hover.
We
we
want
to.
A
We
can
do
you,
can
lay
one
sheet
of
the
the
eight
inch
wide
material
we
could
do
like
two
of
them
or
we
could
even
put
like
a
sheet
of
material.
So
we're
cutting
a
bunch
of
blades
from
from
a
larger
sheet,
not
because
initially
we're
saying,
let's
use
the
half
by
eight
stock,
so
we're
cutting
like
because
we
need
eight
inch
wide
blades,
but
actually
thinking
about
it.
It
might
make
sense
well
why?
Why
do
that?
It's
convenient,
because
you
can
lift
that
you
can
put
it
on
there
easily.
A
Maybe
we
do
a
few
tests
with
it,
but
then,
when
you're
cutting
typically
you
want
to
cut
out
a
bigger
sheets
so
that
you
know
you
load
it
and
you
cut
everything
on
a
whole
table.
So
you'd
be
like
four
by
four
blades
like
16
blades,
at
a
time
which
is
much
more
convenient,
so
once
we
shake
down
the
whole
system,
it's
probably
a
good
idea
to
start
with.
Okay,
we
got
the
sample
cut.
We
know
we
think
we
know
how
to
do
it
and
then
then
go
to
a
bigger
sheet.
A
Now
there's
weight
issues
on
that.
Like
the
big
say,
4x4
sheet,
I
mean
of
half
inch
you're
talking
about
320
pounds
now
so
there's
definite
weight
issues.
When
you
consider
working
with
fatter
bigger,
bigger
stock
pieces,
we
could
probably
do
something
like
maybe
do
something
like
this
wide.
We
just
slip
it
in
there.
You
know,
maybe
four
of
us
carry
it
or
that's
definitely
an
issue
like
at
this
level
like
when
you
have
a
full
torch
table
working
at
the
four
by
four
or
like
four
by
eight
scale.
A
That's
where
you
have
to
have
a
tractor
getting
and
getting
in
there
or
some
kind
of
a
hoist
mechanisms,
we're
actually
loading
in
the
metal
because
for
half
inch
steel,
the
full
sheet
is
640
pounds,
so
it
gets,
gets
heavy
at
this
point,
that's
why
we're
saying?
Okay,
initially,
we
just
used
the
the
half
by
eight
steel
flats,
which
are
you
can
take
like
a
four
foot
piece
and
just
load
it
on
easily.
A
So
it's
easy
to
handle
at
that
level
and
we
can
try
that
or
we
can
try
for
a
bigger
sheet,
but
the
bigger
sheet
I
mean
we
have
to
cut
it
first,
with
a
torch
out
of
the
four
by
eight
sheets
that
we
have,
because
we
can't
do
four
by
eight
on
at
one
time
under
this
yeah.
It's
not,
I
don't
know
it
may
no.
It
actually
may
be
just
wide
enough
that
we
can
slip
the
four
by
eight
like
lengthwise,
but
only
use
like
half
of
it.
So
actually,
I
think.
D
A
Yeah
like
load
it
up,
so
you
load
one
half
in
and
then
you
cut
all
that
out
and
then
slip
the
second
half
in
so
that
that
actually
could
could
be
an
idea.
But
I
mean
that's:
that's
challenging
to
get
it
in
there.
You
have
to
get
the
tractor
in
there
like
put
on
the
forks
and
carry
it
in
there
and
slide
it
in.
A
A
A
A
Yeah
so
that
you're
cutting
into
air,
but
you
destroy
the
the
bomb
you
gotta
have
water
in
there
because
it
will
just
fry
the
metal
underneath
pretty
quick,
yeah
right.
So
typically
they
have
what
they
have.
Is
these
just
slats
and
they
lay
lay
the
slats
on
edge,
and
then
you
put
the
metal
on
and
they're
they're
they're
sacrificial
after
some
time
they
burn
up
and
they
last
longer,
if
you
have
water
in
there.
So
water
is
a
good
idea.
There
yeah.
D
One
other
thing
is
that
we
have
to
decode
like
that:
it
works
whenever
we're
taking
the
signs
that
are
like
the
outer
perimeter
of
it
like.
If
we
loaded
the
g-code
off
the
latest
design,
we
have
it's
going
to
cut
where
we
would
add.
Layers
is
going
to
cut
layers,
and
this
is
going
to
be
slightly
shorter
than
it
would
be.
So
we
need
to
take
into
account
the
width
of
the
plasma
cut.
A
A
So
the
the
main
considerations
on
the
geometry
is
the
eight
by
eight
inch
bearings,
which
we
have,
which
means
that
that's
if
they're
touching
together
so
I
mean
as
far
as
the
we
talked
about
this
before
but
yeah
and
then
just
looking
back
at
the
basic
geometry
like
what's
what's
required
because
there's
actually,
I
think
the
issue
that
we
think
might
be
troublesome
is
not
that
troublesome,
but
there's
another
issue
that
comes
up.
So
let's
take
a
look
at
this
for
a
second.
A
Yeah
so
we
talked
about
the
spacer
anyway,
that's
kind
of
like
all
that
we
have,
but
when
you
no
that
wasn't
there
was
the
we
had
some
more
notes
on
the
large
3d
printer
doc.
Didn't
we.
B
B
A
A
A
A
They're
not
touching
they're,
not
there's
not
going
to
be
interference.
We
we
talked
about
that,
because
this
is
half
inch,
steel
that
that
spade
and
spacer
every
other,
so
there's
a
cutting
blade,
a
spacer
blade.
A
cutting
blade
thing
is
that
one
shaft
and
the
other
shaft
they
have
to
basically
match
up
against
each
other,
so
so
that
consideration
is
real.
As
far
as
like
this
distance
here
I
mean
that
we
can
control,
we've
got
you
know
under
116
control
over
the
cnc
torch
table,
so
that
that
doesn't
worry
me.
A
D
A
So
the
square
tube,
the
4x4
tube
that
goes
around
the
shafts
and
is
welded
so
that
these
square
cutouts
go
around
the
tube.
So
that's
an
easy
way
to
mount
it.
Okay,
that's
cool!
But
how
do
you
space
these
out,
laterally
that
they're
mounted
right
against
each
other
because
they
are
very
tight
against
each
other
when
they
rub
when
they're
actually
going
past
each
other,
because
the
this
blade
is
not
going
against
another
blade,
it's
going
against
a
spacer.
Isn't
it
yeah?
It's
the
shredding
that
happens
between
two
blades.
A
And
this
next
blade
here
and
the
spacers,
the
smaller
spacers.
A
A
A
A
Square
tube,
okay,
so
the
first
so
let's
say:
there's
the
first
blade
right
here
that
you
have
to
adjust
back
and
forth
this
way
precisely
you
do
have
to
do
that.
A
A
A
D
A
There's
a
little
tiny
thing
there:
let's
make
it
red.
A
Because
if
you
just
put
those
like
that,
they
might
be
rubbing
now,
maybe
the
first
try
is
to
actually
see
because
of
inaccuracies.
They
may
not
rub,
but
they
they
will
they're.
I
mean
it's
half
inch
exactly
you're
gonna
have
some
rub
there.
It's
gonna
be
very.
Unless
this
is
like
precision
machined,
then
no
just
the
tolerance
is
within
the
steel,
like
maybe
it
warped
a
little
during
heating.
A
A
A
A
A
A
A
So
we
can
put
in
bolts
like
through
here
now
what
what
what
else
is
required
to
make
that
work.
You
gotta,
you
can
do
something
like
weld
a
nut
here.
A
You
got
to
do
the
same
thing
same
adjustment
on
the
other
shaft,
so
that
you're
now
locating
the
blades
perfectly
along
the
shaft
in
a
place
they
have
to
be,
and
after
they'll
be
punched
against
each
other,
otherwise
they're
all
like
loose,
I
mean
you
can
punch
them
against
each
other
by
sending
a
bolt
through
all
of
them
and
bonding
them
together.
Yeah
that's
more
work.
It
seems
like
this,
this
little
adjustment
collar
here,
let's,
let's
get
a
little
better,
a
better
picture
of
that.
B
A
Three
quarter
inches
convenient
and
easy
to
do
and
strong
enough
to
get
you
plenty
of
force.
So
three
quarter
inch.
B
A
A
A
Can
do
this
thing,
locate
it
right
so
we're
addressing?
How
do
you
make
that
collar
fixed
because
you
got
to
fix
it?
Well,
how
about
we
bottom
one
out
against
the
frame
itself,
there's
the
frame
of
the
box
here,
so
this
gets
remember
how
we
were
watching
the
precious
plastic
video
of
all
their
precision
stuff.
A
This
is
what
we're
doing
here,
not
by
machining
everything,
but
by
using
what
we
have
with
just
like
simple
welds
and
three
inch
collar
and
stuff
like
that.
So
this
is
the
frame,
the
actual
frame,
the
end
end
of
the
box.
A
A
B
A
So
here's
the
bearing
like
the
shaft
comes
oh
yeah,
oh
you're,
right,
they're
yeah
to
to
get
to
get
it
dismantled.
You
have
to
end
the
shaft
there.
D
A
Yeah
yeah,
that's
the
kind
of
complexity
we
have
here.
So
yes,
if
this
collar
bottoms
out
it
can
bottom
out
against
the
bearing
and
spin
with
the
shaft
right
right.
So
there's
the
rotating
collar
of
the
the
bearing
and
then
the
collar
would
be
right
against
it.
A
That
has
to
clear
the
bolts.
This
would
be
right
next
to
it
and
then
so
this
collar
is
spinning.
Everything
here
is
spinning,
including
this
collar,
because
that's
the
bearing
and
then
the
shaft
ends
before
the
frame
you
can
by
taking
out
the
bearing
bolts,
take
out
the
entire
rotor
assembly.
A
Yeah,
that's
what
it
has
to
be
so
there's
the
blades
there's
the
square
tube,
that's
welded
onto
the
three-inch
shaft.
The
consideration
is
that
the
shaft,
as
we
mentioned
now,
has
to
end
before
the
frame.
So
we
got
the
frame
here.
Well,
the
bearing
the
bearing
here
has
to.
B
A
This
is
this
here,
that's
not
too
hard
to
do.
It's
like
as
long
as
we
have
the
collar
welded
onto
this
plate.
While
the
collar
is
already
precision,
that's
precision,
steel
tubing
and
then
the
bolts.
They
have
very
fine
adjustment,
so
you
know,
however,
you
turn
it
it's.
You
know,
millimeters
of
adjustment.
A
D
A
A
Well,
the
entire
color,
the
the
shaft
assembly
I
mean
the
three-inch
shaft
itself-
is
pretty
heavy.
Then
you
put
in
all
these
blades.
This
is
going
to
be
very
heavy
several
hundred
pounds
per
it's
like
400
pounds
per
rotor
or
something
300
depending
I
mean
we'll
start
with
a
few,
a
few
blades,
but
the
shaft
itself.
Right
now
we
have
like
three
feet
or
so,
but
that
weighs
30
pounds
a
foot.
A
A
So
the
shaft
is
30
inches.
So
now
we've
got
minus
the
width
of
the
bearing.
So
now
we've
got
about
you
know,
26
inches.
They
were
30
or
36.
I
think
they
were
three
feet,
so
I've
got
like
30
inches
of
cutting
area
minus
minus
the
two
bearings.
Oh,
my
well
minus
the
collars.
So
it's
like
there's
all
that
space.
So
we're
gonna
end
up
with
like
two
feet
or
so.
A
Yeah
yeah,
we
can
do
that.
Oh,
oh,
but
in
that
case
the
tightening
mechanism
doesn't
work
anymore
because
you'd
have
to
the
square
tube
would
have
to
be
shorter.
So
what
you
can
do
it
is.
You
can
put
a.
B
A
E
A
Is
a
challenge,
though,
because
we
we
need
something
that
something
could
be
as
simple
as
four.
So
if
you've
got
these
bolts
that
are
pressed
supposed
to
press,
you
could
do.
A
A
D
E
D
Afraid
of
is
that
we
power
on
these
powerful
hydraulic
engines.
We
we
miss,
noticing
that
there's
a
slight
snagging
between
them
and
then
we
have
a
bunch
of
metal
just
jamming
into
itself,
because
the
hydraulic
engine
is
strong
right.
A
They're
15
000
inch
pounds
each
meaning
they've
got
at
like
what
is
that
it
we
got
say
eight
inch
blade,
so
the
four
inch
tip
you've
got
like
three
to
four
thousand
pounds,
spread
over
all
the
tips
but
yeah
three
thousand
pounds
pushing
against
each
other.
That's
a
lot
now!
If
you
snag
on
the
metal,
that's
the
metal
is
going
to
stop
it
at
bed
right
there
and
it'll
fluid
bypass
in
the
hydraulic
system.
So
I
mean
the
metal
is
50
000
psi.
So
if
you
snag
a
little
bit,
that's
going
to
stop
it.
A
It's
not
going
to
like
shave
it
off!
It's
it's
too
little
force
for
metal.
It
might
take
little
little
slivers,
tiny
slivers,
but
not
too
much
so
it'll,
probably
just
jam
up,
which
is
fine,
because
we
just
set
the
pressure
bypass
on
the
hydraulics
to
be.
You
know
initially
when
you're
testing
it
set
at
a
low
pressure.
So
you
don't
have
a
lot
of
force.
There
make
sure
it's
all
smooth
so
set
of
like
minimum,
like
you
know,
500
psi
or
whatever,
who.
A
B
F
A
Yes,
as
we
test
that,
so
that's
that
kind
of
the
process
there,
so
that's
the
shredder
cnc
torch,
so
I
mean
I
could
continue.
Maybe
maybe
I
could
start
on
the
shredder
and
get
that,
but
I
mean
we
want
to
cut
it
up
a
little
a
little
bit
here.
We
gotta
that
would
be
very
useful
so
that
we
know
everything
is
gonna
fit
like
all
the
dimensions
got
a
basic
shape.
A
Here
we
wanna
insert
that
that
collar
thing
remove
the
bearings
probably
inside,
take
the
measurements
of
like
exactly
what
we
have
like
that.
We
got
because
we've
got
fixed
things
like
there's
x,
inches
of
shaft.
The
bearings
are
so,
and
so
so
we
can
actually
get
a
accurate
representation
of
that
first.
A
So
how
do
we
divvy
up
divvy
up
the
work,
so
we've
got
work
continuing
on
torch?
Can
you
can
continue
that
yeah
campus?
You
want
to
continue
on
film
enter.
A
Almost
there
we're
at
making
the
z-axis
happen,
so
the
z-axis
we've
got
all
the
parts
for
it
and
we
can
mount
it
and
then
the
it's
pretty
much
about
building
and
attaching
the
z-axis
at
this
point.
So
that's
where
we're
at
right.
There.
A
A
We've
got
this
system
here
with
the
belts,
and
so
we
see
the
three
bearing
holders
which
are
easily
losable
for
any
tightness,
yeah
same
on
a
z,
so
we're
mounting
the
z
between
the
two
two
x
x-axis
as
far
as
the
spacing
between
the
x-axis,
so
you've
got
it
on
already.
We've
got
about
six
inch
such
that
there's
six
inch
space
between
the
two.
Did
you
actually
end
up
measuring
what
we
ended
up
with
as
far
as
the
space
between
the
two.
F
It's
the
is,
I
don't
know
it's
like
about
a
minute.
B
F
An
inch
it's
on
either
side.
A
A
F
A
The
way
we
attach
it
drilling
a
hole
through
here
and
pre-drilling
a
hole
through
these
bushings
here,
which
are
solid
plastic.
We
should
be
able
to
just
get
a
simple
screw
in
there
like
m6
or
or
you
could
even
do
a
deck
screw,
which
has
got
300
pounds
of
holding
strength.
So
here
too,
there's
this
partial.
This
half
have
kind
of
a
bearing
holder
thing
which
just
serves
as
a
mounting
point.
A
So
here
there's
going
to
be
a
bolt
through
that
little
hole
into
the
z,
z
carriage,
but
as
far
as
the
x
carriage,
we
drill
a
hole
through
here
and
mount
into
that
and
then
mount
into
this
other
purple.
One
on
the
bottom
here.
So
four
point
connection
two
uses
using
two
of
these
existing
bearing
holders
which
you
can
just
drill
into
they're,
solid,
solid
plastic
and
then.
A
Yeah,
I
mean
there's
plenty
of
space
here
if
we
need
to
do
any
mounting
so
so
components
like
that
could
go
on
here.
We
can
have
the
the
gas
solenoids
mounted
here
on
the
bottom.
You'd
want
to
have
a
metal
plate
around
the
bottom
surface,
so
you
as
a
heat
shield,
so
just
screw
in
a
metal
plate.
You
can
easily
do
that
through
this
solid
plastic,
which
is
the
bottom
idler.
A
The
relevant
thing
that's
absolutely
needed
for
startup
is,
is
the
z
probe,
which
we
could
attach
it
to
say
this
bottom
plate
here,
but
you
want
to
make
it
a
retractable,
meaning
just
fold
up
or
like
slide
up
on
a
rod
or
something
where,
once
you
get
the
z
measurement,
you
want
to
get
that
out
of
the
flame,
because
if
you
want
it
to
be
as
close
to
the
cutting
tip,
but
once
you're
cutting
you
don't
want
that
to
be
close,
you'd
either
have
to
shield
it
or
just
fold
it
up.
A
A
A
A
A
We
can
pre-drill
like
a
five-millimeter
hole
and
thread
it
right
in
there's
space
there's
meat
there
that
we
can
do
that,
and
so
then
you
mount
your
plate
next
to
it,
and
in
fact,
like
you
know,
do
do
a
couple
of
inches
of
space
there,
so
that
when
thing
is
getting
hot,
you've
got
say
two
inches
of
clear
space.
There
maybe
put
in
little
fans
there
too,
or
something
if
you
want
to
do
that,
but
we
can
definitely
do
it.
You
can
even
do
things
like
multiple
plates.
A
Like
say
you
got
one
plate,
a
nut
and
another
plate,
so
you
just
got
air
air
space
standoffs
between
it,
so
kind
of
like
a
heat
sink
around
around
this
area.
Pla
is
low.
Temperature
like
for
real
we'd,
want
to
do
it
out
of
abs
or
polycarbonate
later
on
yeah.
I
don't
think
that
would
be
a
production
machine
with
pla
which
is
very
low,
low
temperature.
A
With
it
with
a
heat
shield,
I
think
we're
pretty
good,
put
like
a
few
fans
in
there
heat
sinks.
A
If
we,
if
we
needed
to
like
imagine
a
bunch
of
the
same
fans
that
we
have
on
the
extruder
and
the
heat
sinks
mounted
to
a
plate
underneath
here
so
you're,
just
blowing
that
heat
out
each
each
little
fan
is
like
40
watts
of
cooling
power.
So
that's
significant.
A
You
can
say,
and
now
like
the
worst
case
scenario,
is
like
actually
water
cooling,
but
that's.
That
complicates
your
system
quite
a
bit
because
then
you'd
have
to
be
pumping
water
around
your
electronics
here,
but
some
people
do
it.
Some
people
have
water,
cooling
and
these
kinds
of
machines,
so.
A
A
These
are
the
so
yeah
the
actual,
and
we
ended
up
going
with
the
all
the
parallel
mechanism
on
the
left
on
the
y1
side.
Here:
why?
A
E
A
A
B
B
A
A
A
A
There's
the
yeah
there's
the
assembly
for
the
tensioning,
the
blades
together
yeah.
We
could
it's
largely
dependent
on
I'm
doing
a
little
bit
of
cad
work
to
make
sure
it
all
fits.
A
B
A
There's
one
part:
that's
that's
relatively
known
as
the
mounting
pattern
for
the
the
motors,
because
these
motors
have
to
be
mounted
very
tightly
to
the
to
the
base
surface
too.
So
that's
a
four
four
bolt
pattern,
and
that
would
be
similar
to
what
we're
doing
actually
on
the
tractor,
where
we
did
a
basically
a
mounting
plate
for
the
hydraulic
motors
that
would
have
to
be
attached
to
to
the
bottom
bottom
here
to
the
table
that
we're
sitting
on
so
be
some
kind
of
a.
A
A
And
work
out
more
details
of
dimensions,
what's
the
best
way
to
to
do
like
probably
assume.
A
The
connection
so
the
connection
to
the
table
has
to
be
pretty
stiff,
like
there
has
to
be
a
very
stiff
connection
to
at
least
where
the
box
starts
yeah.
I
think
we
have
to
design
that
a
little
more
because
you
can't
just
have
these
motors
kind
of
like
free,
free
hanging
there.
That's
that's
a
lot
of
force
there,
they
gotta,
be
gonna,
have
a
good,
firm
attachment
like
if
there's
a
idea,
we'd,
possibly
do
the
box
and
an
extension
of
the
box
as
a
way
to
hold
it.
A
Or
make
possibly
make
tabs
here
that
then,
once
we
have
the
the
mounts
for
the
motor
the
the
motor
actually
attaches
to
the
tabs
of
of
the
extension
of
the
the
actual
solid
box.
That
would
be
a
good
idea
because
then
you're
bonding
the
actual
box
with
the
motors,
which
are
the
structural
things,
as
opposed
to
relying
say
on
a
table,
a
table
for
your
structure
because
then
table's
bigger.
We
already
have
this
steel
here.
A
It's
convenient
to
use
the
solid
structure
that
we
have
already,
which
has
to
be
structural
already,
to
probably
extend
for
the
motors.
This
may
be
misleading
here.
As
far
as
what
that,
what
the
required
distances
is,
because
these
motors
don't
really
represent,
I
don't
think
they're
accurate
representation
of
what
we
actually
have
this
mounting
plate
here
might
be
much
closer
to
the
box
than
we
think,
in
which
case
it
does
make
a
lot
of
sense
to
connect
to
the
box
itself.
A
A
Do
you
have
the
z-axis
already
alrighty?
Do
you
have
the
z-axis
already
assembled
or.
A
Yeah,
so
I
noticed
there
was
the
original
solenoids
and
then
you
guys
started
doing
the
other
three.
So
what
was
the
idea
there.
B
A
There's
also
the
other
part
of
cleaning
up
the
controller,
so
that
we
can
do
continue
to
do
it
like
well
organized
on
the
nice
panels,
because
that
will
help
all
the
routing
and
everything
else
like
cable
routing
is
gonna,
be
very
important
to
get
everything,
functional
and
routable.
A
Yeah,
so
I
mean
we
have
the
the
pattern,
for
I
mean
pretty
much
exactly
the
same
copy
of
what
we
have
in
the
current
system
on
a
on
a
3d
printer
there's,
a
ac
solenoid
on
it.
If
we
replace
that
one
with
a
dc
one
for
the
gas,
then
we
have
the
basic
control
on
for
the
for
the
cutting
oxygen.
So
probably
the
best
best
would
be
so
manual
just
manually.
We
have
the
torch.
A
We
can
test
with
that
to
automate
it
fully
then
for
the
cutting
sufficient,
it
would
be
pretty
sufficient
to
do
just
the
the
cutting
oxygen
because
that's
the
easiest
system,
and
then
we
can.
A
I
would
start
with
that
and
then,
if
we
want
to
do
the
other
two
gases,
but
that
gets
a
little
it's
doable,
but
I'm
not
sure
if
it's
worth
it
for
the
first
just
for
an
immediate
run,
because
just
one
versus
three
of
them
that
makes
it
one
makes
it
much
easier
to
implement
with
the
one
solid
with
one
relay
that
we
have
so
that
should
that
should
be
in
the
shop.
So
we
got
some
dc
relays
same
form
factor
as
opposed
to
the
ac
one.
A
So
if
we
do
that,
then
we
can
be
pretty
close
to
testing
it.
The
first
thing
is
yeah,
I
mean
just
get
the
motion
so
after
get
getting
the
motion
system
up
and
running
just
test
see
if
we
can
get
the
some
sample
g
code
files
and
run
it,
but
we
do
have
to
do
the
calibrations
for
the
the
motion,
like
the
z
steps
per
per
millimeter
and
that
how
do
we
do
that?
F
A
Have
to
measure
yeah
I
mean
because
now
now
we
we
have
a
different
amount
of
the
pulleys
are
different
size.
So
the
z,
sorry,
not
z,
steps
steps
per
millimeter
on
the
x
and
y
and
z,
which
are
all
the
same,
because
we've
got
the
same
pulleys
on
all
three
axes,
but
that's
going
to
be
a
a
simple
factor.
A
We
can
start
probably
by
saying.
Okay,
we
used
a
half
inch
now
we're
using
the
0.74
one
inch
or
whatever
we're
using
right
now,
based
on
it's
in
a
document.
Actually,
it's
we
have
the
pulley
specs,
so
you
can
start
by
saying:
that's
that's
the
factor
difference
between
a
pulley
we
have
now
and
what
we
had
before.
That's
a
good
initial
start
and
see
if
we
get
pretty
accurate
results
like
if
we
say
we
move
it.
A
F
B
C
A
F
A
F
F
Do
one
x-axis
in
place
using
just
the
handle.
F
A
Yeah
yeah,
I
mean
there's
once
again
like
with
the
freecad
the
parallel
workflow.
The
idea
there
is
what
we
practice
is
the
is
the
interface
design
idea.
That
means
you
know
there
are
certain
known
things
about
the
whole
system
when
you
can
define
okay,
this
is
the
blade.
This
is
how
it
fits
on
the
tube,
like
you
can
get
that
broke,
break
down
the
whole
design
into
a
whole
number
like
for
basically
for
each
part,
exactly
what?
A
Where
is
it,
how
it
fits,
and
you
can
do
a
design
process
with
multiple
people
doing
that,
so
we
can
definitely
collaborate
on
it,
because
it's
once
again
a
total
modular
breakdown.
C
Shredder
of
the
starter
started
is
probably
where
I
could
add
the
most
value
and
it
looks
like
the
dependency
is
being
able
to
sort
of
rectify
what
we
physically
have.
You
know
known
with
the
components
that
we're
using
versus
you
know,
making
the
adjustments
in
the
hand
and
then
being
able
to
time
a
lot
of
some
of
the
design,
and
so
I
think
I
should
get
up
to
speed
on
using
freecad.
You
know
take
some
measurements
with
what
we
have
here
and
then
start
seeing
if
we
can
get
a
unification
of
what's
in
the
shop.
A
A
Components
or
the
final
final
design
just
keep
uploading
on
a
regular
basis,
and
you
have
to
wait
to
finish
it.
It's
also
a
good
way
to
save
files
from
your
computer
in
case
you
crash
and
stuff
like
that,
but
why
I
do
it
is
as
soon
as
I
have
a
change.
I
keep
the
log
of
okay.
How
did
I
make
the
changes
like,
for
example,
on
a
torch
table?
I
think
that's
a
good
example.
A
A
Look
at
all
that
so,
basically,
starting
with
this
and
the
various
additions
and
happening
you
can
kind
of
trace,
you
know
say
from
here
yeah
just
doing
a
visual
record
of
what
what
happened
like
initially,
for
example,
yeah
started
with
the
y
axis
and
kept
moving,
and-
and
this
actually
does
show
the
progress
of
one
thing
after
another,
like,
for
example,
the
the
z
mounts
were
added
in
this
file
version
and
stuff,
like
that,
just
continuing
and
the
same
for
the.
A
A
What's
useful,
is
you
once
again
upload
new
version
of
the
file
and
there's
yeah,
there's
like
a
whole
bunch
and
then
a
comment
like
when
you
whenever
you,
whenever
you
click
upload
a
new
version
of
the
file,
you
select
the
file,
but
also
it
lets
you
do
the
file
changes
notes.
So
you
can
put
a
few
notes
in
there,
so
it's
kind
of
transparent,
because
because,
unlike
software,
this
is
actually
a
little
different
in
the
sense
that
multiple
files
are
useful,
some
files
might
have
the
full
detail.
A
A
It's
not
super
visible
in
this
final
assembly,
but
in
individual
part
files.
That's
where
it's
important!
You
have
like
the
full
detail,
file
like
say
even
with
threads,
which
take
a
lot
of
memory,
but
then
you
strip
all
that
detail
down.
If
you
want
to
work
in
a
larger
assembly
where,
if
you
had,
if
you
didn't
do
the
simplifications,
your
files
would
be
many
many
megabytes
and
be
super
slow
and
stuff
like
that.
So
in
this
kind
of
process
we
we
save.
A
We
can
save
different
versions
of
the
file
like
it's,
not
just
the
production
version.
There
might
be
some
variations
that
maybe
we're
testing
something
out.
It
doesn't
mean
that,
like
the
latest
file
is,
is
the
master.
Even
it
could
mean
that
okay,
we're
going
that,
but
going
with
that
direction,
but
we
can
actually
go
back
to
performer
files
and
say:
okay.
Well,
I
actually
like
that.
A
Maybe
I
want
to
start
from
there
and
stuff
like
that,
so
so
there's
multiple
files,
which
is
a
little
different
than
the
software
out,
because
typically
it's
like
you
got
the
whole
just
like
that.
One
one
version
that
people
are
process
working
with
little
different,
but
but
we
do
want
to
save
like
as
much
of
the
process
as
possible
and
study
the
history
for
what's
been
done.
