A
Okay,
so
let's
take
a
look
at
the
critical
path.
Yesterday
we
talked
about
the
schedule
for
just
to
review.
What's
on
the
plate
for
current
work,
we've
got
the
big
ideas.
If
we
at
the
end
of
this
month,
we
can
start
shredding
and
making
filament
shredding
waste
plastic,
making
filament.
That
will
be
a
major
accomplishment
for
the
world
of
open
source,
we're
kind
of
jumbling
up
around
the
the
workshops.
A
The
bigger
plan
was
just
as
far
as
the
schedule
there
was
so
talking
about
the
so
after
the
large
printer
build.
The
thing
we're
quite
interested
about
is
cnc
torch
table,
filament,
maker
plastic,
shredder
terms
of
difficulty
level.
Plastic
cnc
torch
table
is
a
torch
on
a
cnc
gantry.
A
If
we
get
the
cnc
gantry,
we've
got
the
torch,
so
if,
in
the
next
day
or
two,
we
master
the
axes-
and
there
are
some
issues-
there's
a
couple
of
things
like,
for
example,
yesterday,
one
of
the
z
motors,
the
the
pulley
is
not
on
it's
just
slipping.
So
whoever
did
that
we
got
to
do
the
two
say.
A
Yeah,
that's
the
better
question
who
didn't
do
it
because
it
wasn't
on
tight
the
procedure
there
is
to
get
the
two
set
screws
on
tight.
I
actually
do
a
little
dab
of
crazy
glue
on
the
shaft,
so
you
can
still
take
it
off,
but
you
guarantee
more
that
it
does
not
slip
because
it's
one
of
those
things
now
we
got
to
take
it
off
it's
not
too
bad
because
we
can
take
it
off
readily,
except
for
the
little
nuts
there
on
the
motor
they're
kind
of
tiny
you're
gonna
have
to
finagle.
C
A
E
A
A
A
If
we
have
the
xyz
axis,
we've
got
torch,
easy
done
it
in
2000,
eight
or
nine,
so
why
we
did
it
now,
because
we
made
improvements
every
single
time,
and
it
was
one
of
those
things
that
it's
complex
enough
that
you
had
one
group
come
in,
they
got
so
far
then
completed.
Another
group
came
in
got
so
far
never
completed
it.
We
tried
things
such
as
custom,
stepper
drivers
that
someone
else,
someone
designed
cool
but
never
got
completed,
because
that's
a
development
project.
What
are
we
doing
now?
A
A
So
we
didn't
do
this
marlin,
the
simple
control
software
for
the
3d
printers,
which
we're
now
using
to
to
run
all
the
cnc
machines.
So
those
two
things
waiting
up
years,
ignore
it
and
it
will
go
away
so
solutions
come
up.
What
else
was
was
an
issue?
We
didn't
have
the
universal
access.
At
that
time
we
were
basically
doing
custom
design
like,
however,
we
could
do
it
with
rails
and
bearings,
and
all
of
that
so
was
it
a
complete
redesign.
A
Yes,
because
the
initial
prototype
is
like
look
at
the
first
prototype
how
it
looked,
you
can
probably
see
what's
wrong
with
it.
So
well,
let's
see
if
somebody
can
see
what's
wrong
with
it.
F
A
A
A
So
but
okay,
you
look
at
the
gantry,
you
can't
see
much
of
the
detail,
but
it's
rails,
a
bunch
of
bolts,
let's
see
make
zine,
let's
take
a
picture
of
how
it
looked
actually,
but
look
at
it.
That's
that
frame
still
stands.
A
It's
actually
in
the
old
workshop
there,
where
it
is
right
there
that
was
the
old
workshop.
But
if
you
look
at
the
design
nightmare,
it's
a
nightmare
to
put
together
how
many
little
bolts
and
screws
do
you
have
there
that
to
do
that,
you
know
blah
blah
blah
this
and
that
everything
like
threaded
rod.
A
This
thing
is
attached
with
like
a
bunch
of
screws.
The
part
to
count
is
huge.
Unique
part
count
is
not
huge.
That's
why
we
thought.
Oh,
this
is
really
cool.
All
we're
using
is
tubing
little
flat
plate
and
then
like
this.
U
channel
for
the
frame,
but
everything
about
it
is
a
pain
like
okay,
so
bolting,
together
everything
it's
running
on
this.
This
is
using
linear
gear,
rack,
yeah
and
metal
gears
right
now
we're
doing
the
belts
and
stuff
like
that
cool,
but
I
mean
the
learning
from
that.
A
Is
it's
like
to
fix
anything?
You
know
you
take
out
part
one
screw
and
you
know
everything
kind
of
falls
apart,
so
every
screw
has
to
be
tight
and
all
that
we
can't
even
get
one
screw
on
the
pulley
right
right
now.
So
if
you've
got
a
hundred
of
them,
it
just
makes
it
really
complicated
to
maintain
it's,
not
a
production
machine.
A
A
If
you
use
right
now,
we
even
have
the
gas
control,
which
is
now
under
our
hand,
and
you
can
control
that
through
ramps
just
turn
on
one
of
the
pins,
so
but
there's
only
really
one
well
controllable,
pin
that
we
have
ready
access
to
through
terminals.
A
It's
that
there's
d89
d10
like
d9
is
open.
The
other
ones
are
they're
connected
to
no
there's
actually
two
of
them.
There's
the
fan
and
the
the
heat
bed,
no
just
the
one,
because
the
two
other
ones
they
require
thermistors.
So
you
have
like
temperature
sensing,
so
that
kind
of
complicates
things
so
you've
got
one,
but
you've
got
plenty
pins
on
the
arduino
mega.
H
A
See
here
so
going
back
into
the
large
3d
printer
dock,
because
this
is
like,
if
we
get
serious
about
this
and
actually
do
auto
gas
control
which
which
is
readily
doable,
it's
readily
doable
like
right
now,
ramps
take
one
of
the
ex
the
pins
that
are
on
ramps.
A
So
let's
talk
about
trigger
gas
trigger
on
torch,
just
for
a
second
because,
as
we
said,
if
we
give
the
printer
the
torches
gas
trigger,
plus
xyz
motion,
as
opposed
to
extruder
plus
xyz
motion.
A
Yeah,
it's
three
of
them
because
you
gotta
have
how
many
gases
do
you
need
to
to
actually
work?
So
look
at
the
2019
build
here.
If
you
look
at
the
okay,
so
let's
look
at
the
that's
the
z-axis,
that's
our
z-axis
right
now!
So
it's
riding
on
x
y!
You
don't
need
the
full
z
setup.
It's
just
the
z
is
actually
the
z
axis
is
riding
on
the
x.
A
So
here's
what
you
saw
that
it
that
is
it
so
three.
You
need
three
so
for
auto
gas
control
on
a
torch.
You
need
a
three
hose
torch.
So
what
we
did
is
slice
apart.
That's
all
you
need
that
little
tip
there
and
put
three
hoses
on
it
and
run
them
through
the
solids.
That's
a
torch!
That's
it!
All!
You
need
is
a
nozzle
to
send
gas
through.
H
A
A
A
A
You
know
50
bucks
for
this
or
100
bucks
for
this
entire
torch
assembly.
Then
you
just
cut
off
the
three
hoses
the
metal
and
put
your
tubes
and
connect
them
to
the
solenoids.
So
you
connect
them
to
these
three
here.
A
D
A
A
B
I
A
So
we
actually
have
a
an
igniter
on
that
torch
assembly.
There
too,
which
is
not
shown
here,
but
it's
it's
on
it.
A
Igniter
is
a
neon
light,
high
voltage
transformer
and
then
a
spark
element
just
one
of
those
like
gas,
stove
lighter
elements.
So
we
do
but
okay
logic
start
with
the
selling.
We
can
light
it
by
hand.
We
can
use
that
use
the
igniter.
I
would
start
by
hand
do
the
igniter
once
we
master
the
gas
flow,
because
that's
an
extra
it's,
you
can
easily
light
it
up
front
and
because
that
would
require
anything
here.
We
talk
about
debugging,
rapid
prototyping
means
you
do
the
simplest
thing.
A
A
A
A
Yeah,
if
you
want
to
be
granular
about
it
indeed,
yeah
light
it
light
acetylene
sure
light
acetylene
turn
on
oxygen.
This
is
just
the
oxygen
to
get
a
blue
flame,
so
this
is
not
cutting
oxygen.
Cutting
oxygen
with
what
this
oxygen
does
it's
a
heating
flame?
It's
not
a
cutting
flame.
The
cutting
flame
is
where
you
have
a
strong,
stronger
stream
of
oxygen
going
straight
through
and
the
way
the
torch
is
designed.
It
has
one
low
pressure.
It
regulates
it
such
that
the
the
one
oxygen
flow
is
at
low
pressure.
A
Once
you
trigger
the
trigger
the
handle,
you
get
the
higher
pressure
which
is
for
cutting,
so
once
it's
molten
it
cuts
with
that
pure
oxygen.
More
oxygen
means
it
just
blows
that
just
lights,
it
like
paper
and
blows
it
through
so
turn
on
oxygen,
which
is
the
heating
oxygen.
F
In
terms
of,
like
you
know,
safety,
the
cost
of
you
know
gas
and
ease
of
you
know:
operation
maintenance,
things
like
that,
and
maybe
even
flexibility
applications
is,
is
the
difference
between
like
a
plasma.
A
A
Like
the
tips,
I
think
it's
all
together
more
expensive
than
acetylene,
but
the
thing
that
gets
you
is,
you
can
only
cut
so
much
with
a
with
a
plasma.
You'll
be
good
for
like
up
to
an
inch
which
is
for
most
purposes
good,
but
it
will
be
slower
and
the
machine
to
do
that
is,
gets
pretty
expensive
to
do.
One
inch
you're
getting
into
like
five
thousand
dollar
plasma
cutters
like
thousand
dollar
cutters,
are
going
to
be
like
half
inch
easy.
You
know,
and
that's
kind
of
stuff
is
that's
power.
A
Electronics,
that's
actually
going
down
in
price,
but
yeah
for
any
industrial
activity.
You're
talking
about
5000
and
up,
whereas
once
again
the
torch
head
is
dollars
here
so
and
and
it
can
do
seven
inches,
this
one
can
do
seven
inches
of
steel
so
more
than
what
we
need
right
now
so
up,
but
up
as
far
as
operating
costs.
Why
the
why
the
gas
control
is
useful
is
because
then
we
can,
if
we
go
more
advanced
than
this
like
this,
is
future
work.
A
So,
as
I
mentioned
before,
you
don't
need
a
lot
of
gas
once
you're
cutting,
so
you
would
turn
down
your
acetylene
once
you
start
the
cut
to
save
gas,
so
you
could
reduce
your
acetylene
use
it
probably
like
75,
which
would
mean
operating
costs,
go
down
and
oxygen.
You
can
get
from
electrolysis
rather
easily.
If
you
have
an
off-grid
african
operation
or
something
like
that,
but
the
acetylene
you
still
need,
but
then
again
in
the
future
iteration
it's
hydrogen.
Hydrogen
is
far
superior
to
acetylene.
C
A
Yeah,
yes,
the
idea
there
is,
it
doesn't
also
carburize
doesn't
harden
the
steel
like
the
carbon
in
the
acetylene,
it's
good
for
what
we
want
to
do
for
the
blades,
because
it
actually
hardens
the
blade
tips.
A
So
actually
hydrogen
would
be
worse
for
our
purpose,
because
actually
hardening
of
the
blades
so
you'd
have
to
start
with
harder
steel
to
get
an
equivalent
grinder
shredder.
E
A
Okay
and
you've
got
oxygen
and
acetylene
well
for
all
the
travel
like
in
the
more
advanced
version
with
the
igniter.
Yes,
you
go
turn
everything
off
next
hull
turn
everything
on.
That's
that's
cool,
because
you
can
save
a
lot
of
a
lot
of
money
on
the
gases
when
you
turn
them
off
in
all
the
travels
and
all
that
and
you
just
turn
up
turn
it
on
when
you
need
it.
Otherwise,
it's
just
on
all
the
time
and
that's
so.
A
This
is
like,
if
you
have
the
proportional
valve,
which
I
haven't
even
looked
into
that
because
they're
going
to
get
expensive,
they're,
probably
going
to
be
like
a
few
hundred
bucks,
a
just
like
adjustable
solenoid
valve
gas,
solenoid
valve,
I
never
even
googled
it
well.
D
A
But
I
got
scared
off
once
I
see
the
prices
or
adjustable
well,
actually
what
you
can
do,
oh
yeah,
so
there's
other
ways
to
do
it.
If
these
are
not,
are
these
adjustable
they're
hard
to
find
even
oh
here,
adjustable
gas
solenoid
valve?
A
Oh,
if
it's
adjustable
so
no
they're,
actually
they're
cheap,
okay.
So
here's
how
you
would
do
it
it's
adjustable,
but
not
electronically?
I
don't
think
that's
adjustable
electronically.
You
can
do
it,
but
then
you
can
have
two
valves
so
turn
on
one
for
the
regular
flow,
then,
when
you're
starting
to
cut
just
turn
on
the
other
valve,
which
has
the
low
very
low
flow.
A
A
Well
manual,
like
you
said
it
at
the
beginning,
you
said
it
once
and
then
you
turn
either
the
high
flow
for
acetylene
or
you
turn
that
off
and
turn
on
the
low
flow
acetylene
valve,
because
they're
they're
in
parallel
they're
feeding
into
the
same
same
aperture
cool.
So
we
can
do
that
inexpensively
and
we've
got
these.
Are
you
know
20
bucks
or
so
each
something
like
that?
20
30,
40
bucks.
A
So
that's
the
logic.
Okay,
but
let's
look
at
the
mega
arduino
mega
the
ramps.
Let's
look
at
ramps.
What
we
have
available
to
control
this
so
and
we've
been
so
ramps.
Well,
let's
look
at.
C
H
A
So
if
you
look
at
this
diagram,
so
that's
your
ramps.
That's
all
the
pins!
If
you
can
recognize
that,
but
there's
a
bunch
of
pins
like,
for
example,
auxiliary
here
tap
any
one
of
those
pins
with.
A
Jumper
cables,
you
tap
that
so
there's
like
plus
there's
a
bunch
of
pins
out
there
ground
and
and
signal
tap
that
and
turn
it
on
in
marlin
g
code.
And
how
do
you
do
that?
We
did
that
the
other
day.
What
was
that
it
was
like
actually
put
it
in
my
pictures,
there's
a
yeah!
So
one
of
these
jumpers,
you
connect
it
to
one
of
the
pins
on
your
ramps,
connect
the
other.
A
So
that's
a
trigger
signal.
You'd
have
to
go
through
a
solenoid
to
trigger
the
solenoid
valve.
There's
a
solenoid
switch
or
solid-state
relay
like
a
dc
relay
to
trigger
the
valve
itself.
So
before
the
valve,
you
can't
really
do
it
through
the
arduino.
You
have
to
put
another
like
the
solid
state
relay
like
we
have,
which
do
we
get
it
to
work
on
dc.
A
I
think
we
got
it
to
work
on
dc,
so
one
of
the
relays
that
we
have
you
can
use
that
to
trigger
this,
the
gas
solenoid.
So
that
would
be
a
little
project
here
and
the
command
there.
A
A
A
No
m104
was
to
heat
m42
m42
is
a
command
that
you
would
type
in
like
you
have
gcode
files
that
you
put
in
on
marlin
if
you
type
in
m42
space
p44,
that
would
turn
on
pin
44
s1.
I
think
that's
for
one
second
or
whatever.
That
is
it's.
This
is
this
stuff
is
where
you
find
this
stuff.
So,
first
of
all,
let's
take
a
look
at
put
this
in
here.
That's
that's
our
secret
codes,
but
where
do
you
learn
more
about
this?
This
is
under
marlin
documentation.
A
Oh
yeah
s,
s
is
like
the
level
like
s0
would
be.
I
guess.
A
S
zero
would
be
to
turn
it
off.
The
state
is
from
zero
to
two
twenty
two,
two
five
five
and
then
you
do
delay
a
delay
command,
delay
1000.
That
does
a
delay
of
no.
How
do
you
do
delay
here?
Where's
that.
A
What
is
yeah
yeah
there's
another
code
for
delay,
which
is
what's
the
delay
code?
Oh
g4,
p6000
g4
is
the
delay
so
that
delays
60
000
milliseconds,
no,
that's
milliseconds,
so
that's
seconds
or
so
yeah.
So
we
would
look
at
g4
g4.
A
Now
what
was
what
am
I
saying?
G4
yeah
g4
g4
marlin
dwell
yeah,
so
you
do
g4
for
p
500.
A
Like
s
and
what's
s
versus
p,
I
don't
know
one
is
seconds,
one
is
whatever
that's
one
second,
so
you
do
g4.
So
we
can
do
this.
This
is
for
timing,
but
anyway,
here
the
timing.
A
How
do
we
generate
this
g-code
to
do
this?
You
could
do
it
completely
manually.
You
can
say
well
now
forget
about
not
for
the
not
for
the
blades.
You
go
into.
A
Kira
would
be
one
way
so
v4.
A
Right,
so
that's
so
like
one
of
these
pins,
these
auxiliary
pins,
you
can
just
attach
one
of
these
wires
to
it,
go
to
the
solid
state
relay
and
that's
it,
that's
really
it
you
got.
You
need
two
wires.
One
is
ground.
One
is
the
signal
wire,
so
here
two
pins
that
you
end
up
using
so
one
wire
per
pin.
E
A
Generate
cut
file,
there's
many
different
ways:
there's
when
I've
used
this
dxf
to
g-code.
A
A
Yeah,
if
you
google,
what's
the
best
way,
who
does
this
so
so?
Who
are
people
that
do
it
do
this?
It
would
be.
What
is
that
thing?
The
mpcnc
does
it
so
you
can
look
at
how
they
do
it.
Mpcnc
cut
file
generation.
A
Let's
I'm
looking
for
dxf
to
g
code,
let's
see
if
the
actual
file
is
on
the
wiki,
because
if
you
have
that,
that's
all
you
need
you
get
a
dxf
file.
You
run
that
code.
It
gets
you
a
g-code
file
and
you
put
that
on
your
sd
card
and
you
put
it
on
the
printer.
That's
it
and
then.
A
A
A
A
Yeah?
I
think
it's
working
free,
cad
to
path
generation
and
free
cad.
You
could
also
do
in
free
cat
directly
there's
a
path
workbench.
H
A
Let's
look
at
free
cut
the
g
code.
A
You
can
take
a
look
at
this,
but
if
you
have
a
file,
it'll
get
you
the
actual
g-code
by
running
this
workbench,
but
I
want
to
minimize
the
learning
or
maybe
maybe
I'll,
look
up.
What's
the
simplest,
I
think
finding
the
the
accepted
g-code
yeah.
I
think
it's
probably
the
simplest,
because
this
this
has
a
little
bit
of
learning
curve
to
it.
A
Yeah,
but
they
do
have
that
because
they
do
2d
cnc.
Okay,
like
control,
f2d
yeah,
like.
A
E
A
Not
not
a
hard
thing,
not
too
hard
to
do
that.
It's
we've
done
it.
I
just
gotta,
look
up
what
the
current
best
thing.
I
think
the
accepted
g-code
will
be
the
best
tool.
So
let's
maybe
just
link
it
to
here.
It's
a
simple
one.
It's
a
little
python
script.
A
Take
a
look
at
so
the
diagram
depends.
I
mean
this.
This
is
what
you're
going
to
look
at.
That's
just
a
diagram
of
all
the
pins
they're
numbered
like,
for
example,
you
saw
44.
So
if
we
connect
to
this
pin
right
there
you'll
trigger
whatever
you
got
connected
to
that
pin,
so
you
have
to
correlate
this
to.
H
A
Or
for
the
most
simple
thing,
if
we
use
turn
on
the
fan,
which
is
the
available,
we
could
probably
start
with
that.
As
the
easiest
thing
use.
One
version
is
you
put
the
header
torch
head
on
you
trigger
it
manually,
you
cut,
you
can
do
that
might
be
step.
One
step
two
would
be
turn
on
the
oxygen
and
acetylene
just
the
regular
flame
and
then
turn
it
on
using
d9,
which
is
the
code
for
turning
on
blower
fan.
A
So
you
have
ready
terminals,
you
don't
have
to
mess
with
a
solid
state
relay.
That's
triggering
your
your
solenoid.
That
could,
by
itself
trigger
your
little
relay,
but
you
have
to
be
a
little
careful
about
that
because
upon
snapping
back
turning
off,
there's
there's
some
back
emf
happening
so
that
might
fry
your
board.
So
I
I
would
be
now.
A
Yeah
a
diode,
so
we
would
do
right
now
we
have
the
blower
fan.
We
would
connect
that
output.
I
would
still
go
through
the
solid
state
relay
because
that
will
block
that
back.
Emf
thing.
That's
so
when
you
have
it
because
the
relay
is
a
spring,
a
coil
that's
moved
by,
but
when
you
spring
back,
you
generate
electricity,
it's
a
generator!
It's
a
linear
motor,
but
motors
are
generators
too.
A
So
you
get
this
back
back
electricity
happening
that
can
fry
your
board.
So,
as
you
see,
there's
detail
here
that
you
have
to
pay
attention
to
just
the
just
the
back
emf.
It's
called
back
electromotive
force
back
voltage
that
you
get
from
relays,
but
that's
that
so
that's
gas
trigger.
But
let's
move
on
to
like
the
bigger
like
beyond
this,
so
there's
torch,
so
there's
torch
to
shredder.
A
So
what
exactly
is
the
easiest
way
to
do
this?
So
for
the
shredder?
We
do
have
our
chunky,
hydraulic
motors
and
we
have
power
cubes,
so
we
can
couple
the
shafts
directly
to
them
and
in
fact,
one
convenient
way
since
we've
already
done
it
is
take
the
three
inch
shaft
now
this
is
getting
pretty
industrial
here.
So
three
inch
shaft
put
the
square
tubing
on
it.
A
Mount
the
blades
through
the
square
holes
that
so
are
are
mounting
for
the
blades
is
the
square
hole,
so
you
don't
need
any
set
screws
or
any
stuff
like
that,
it's
good
to
use
a
geometrical
shaft
so
that
you
don't
have
to
worry
about
any
set
screws
there.
Otherwise,
the
things
slip
so
in
a
heavy
duty
application
like
a
shredder.
A
You
want
a
shaft
that
has
a
geometry
like
hexagon
or
something
so
that
you
don't
slip
the
blades,
because
there's
a
lot
of
force
on
the
blades
and
to
get
you
know,
every
single
blade
would
have
to
have
a
set
screw
of
some
sort.
If
you
didn't
do
that,
which
is
like
impossible
to
do.
A
A
I
mean
that's
the
idea,
just
get
the
whole
picture
of
what's
if
we
wanted
to
do
this,
what
it
takes
so
because
we've
got
like
two
good
weeks,
but
if
we
go
at
the
present
state
of
we're
just
saying:
oh
we're
just
troubleshooting
the
next
and
next
problem
on
the
printer.
A
It's
gonna
be
two
weeks
and
that's
all
we're
gonna
do
so.
You're
gonna
have
to
understand
for
yourself.
The
way
you
can
pace
yourself
is
that
okay,
is
this
critical
to
to
getting
there
and
you'll
be
able
to
judge
okay?
Well,
that's!
Maybe
not!
Let's
move
on
kind
of
deal
so
you'll
be
self
self-guided
to
say.
Okay,
let's
move
on
past
certain
things,
that'll
be
the
ideal
goal,
but
here
we've
got
the
hydraulic
motors.
You
got
the
three
inch
shaft
plus
square
tube.
A
A
Three
inch
ready
to
be
coupled
to
three
inch:
shaft
okay,
so
they
got
they've
got
shaft
with
that's
three
foot
long
with
a
key
way,
so
they
did
the
key
way,
because
so
we've
got
that.
So
this
is
the
shaft
plus
square
tube,
and
then
you
have
bearing
so
a
big
three
inch,
bearing
here
big
three
inch
bearing
here
and
then
on
the
other
side.
I
A
A
A
A
A
Oh,
yes,
you
gotta
mount
so
there's
more
plates
like,
for
example,
here
you're
gonna
mount
the
motors
just
like
comparable
to
before,
like
this
on
another
plate,
which
is
mounted
to
a
base
of
some
sort.
A
Now,
underneath
this
you'd
want
to
have
mesh
which,
like
perforated
mesh,
which
that
determines
the
size
of
particles
that
will
get
through
so
this
when
you
throw
stuff
in
there,
it
will
keep
getting
re-ground
until
it
falls
through
a
mesh.
That's
under
the
the
grinders
and
the
whole
size
is
in
a
mesh,
determine
what
particles
come
out
of
the
machine.
A
So
we
do
have
some
mesh
that
we
can
use
for
this,
or
we
can
actually
get
some
more
from
mcmaster
car
because
we
probably
want
to
get
like,
like
3
8
inch
or
quarter
inch
mesh,
so
that
the
particles
of
plastic
that
we're
working
with
are
up
to
like
a
quarter
quarter.
C
C
A
G
C
A
Gooey
well,
but
you
see
like
it's
going
like
this,
so
if
it
falls
down
and
gets
caught
there,
it
gets
sent
back
up.
So
it
should
work
like
that,
but
maybe
not
we'll
see
when
we've
done
that
with
our
smaller
shredders
we've
got
the
smaller
shredder
parts
here,
but
you
can
see
that
yeah
stuff
fell
through,
but
that
was
yeah
here.
A
You
probably
want
to
have
like
larger
holes
larger
if
you're
doing
like
half
inch
shreds
it
depends
on
the
spacing
between
the
blades
whatever's
gonna
fall
through
is
gonna,
be
limited
by
the
size
of
the
aperture
like
when
the
blades
are
going
past
each
other.
If
you
got
half
inch
like
you,
don't
expect
particles
larger
than
half
inch
to
go
through
unless
it's
like
a
long
strand
of
something
so
and
if
they're
tightly
spaced.
A
If
there's
space
to
within
like
say,
eighth
of
an
inch
I
mean
you
can't
have
anything
more
than
in
theory,
half
half
inch
wide
half
inch
long
by
one
eighth
inch,
but
I
mean
a
little
like
plastic
will
deform
and
stuff
like
that.
So
if
you
have
the
blades
spaced
pretty
closely
the
particles
coming
out
on
the
other
side,
I
mean
you
can't
just
get
you
can't
just
send
through
huge
chunks.
A
What
happens
is
that
you
keep
scraping
on
that
and
the
things
that
through
come
through
have
to
be
pretty
small,
depending
on
your
blade,
spacing
yeah,
but
that's
that's
as
simple
as
that,
but
well
yeah
we
could
probably
try.
A
Probably
a
first
good
pass
would
be
no
screen
at
all
because
we'll
see
what
kind
of
particle
size
we
get
after
that
and
if
you
have
a
big
bin,
like
you
know,
like
a
thing
like
this,
so
we're
talking
about
throwing
in
a
bunch
of
stuff
like
a
55
gallon
drum
at
a
time
just
collect
it
all,
maybe
run
it
through
again
or
5
gallon
buckets
as
a
start
just
run.
A
A
Yeah
when
we
get
there
yeah,
so
that's
the
easiest
design
for
a
shredder.
It's
it's
heavy
hydraulics,
so
the
motors
are
run
in
parallel
off
a
power
cube
which
is
like
the
micro
track
or
whatever
the
bearings
we
have
experience
with
shafts.
We
already
did
that
and
the
chain
the
coupling,
because
we
have
the
double
chain
coupler
with
a
keyway
in
it
I
mean
yeah,
we're
guaranteed
pretty
good
connection.
There's
no
failure
point
there,
so
this
is
like
pretty
much
guaranteed
to
work.
B
A
By
plate,
yeah,
okay,
here
we've
got
the
plates.
We
moved
into
the
steel
rack
yesterday,
so
so
easiest
design
for
a
filament
maker.
A
C
Want
to
be
printing,
we
need
like
one
of
those
big
like
electrical
wire
drums.
That's
huge,
like
forefoot,.
C
One
one
question:
that's
slightly
aside:
is
there
any
reason
to
not
use
a
bigger
diameter
bead
of
filament.
A
G
A
A
So
what
is
this
thing?
It's
a.
A
A
Yeah,
so
that's
that's
not
adequate,
but.
A
Marginally,
yes,
so,
okay,
what's
going
on
here,
that's
a
3d,
printed,
casing:
electronics
inside
cnc,
cut
mdf,
copper!
All
complexity!
Don't
need
any
of
this.
You
need
a
box
and
a
one
inch
pipe
through.
It
had
a
motor
attached
to
it
and
a
heater
on
the
bottom
so
get
rid
of
the
electronics.
We've
got
the
universal
controller.
A
Same
controllers,
on
a
torch
table
or
on
a
big
printer
use
that
connected
to
sense
the
temperature
in
the
heater
element
for
heater
element.
You
have
bands,
just
these
one-inch
bands,
120
volts,
get
a
one-inch
pipe
get
a
one-inch
auger
through
it
attach
a
motor
to
it,
and
you're
done.
Concept
is
simple:.
A
A
And
here
the
heat
does
all
the
work
in
principle
upon
startup
you're
gonna
have
a
bunch
of
molten
mass
in
there.
So
that's
where
you
would
need
some
more
help,
but
in
principle
the
motor
power
requirements
are
not
too
huge,
because
you've
got
molten
plastic,
which
is
relatively
easy
to
move
around.
It's
it
flows.
A
In
fact,
if
you're
flowing
plastic,
this
thing
would
dribble
plastic
out
the
bottom,
so
the
auger
is
force
requirements
on
that.
Aren't
too
big?
We
can
we
have
choices
of
what
to
do.
We
can
use
that
same
motor
that
we
have
there.
We
can
use
the
we
have
that
we
have
this
filament
maker
in
a
shop,
and
maybe
actually
we
can
run
this
for
a
second.
A
I
mean
the
design
here.
That's
too
complicated,
like
that
plastic
is
thin.
All
the
electronics
are
hidden.
You
can't
see
what's
going
on
inside,
it's
not
super
transparent,
it
requires
pellets,
not
regrind.
It
can't
work
with
re-grind
it's
too
finicky,
so
it
requires
very
nice,
precise
pellets.
So
we
need
a
more.
A
Where's
the
file
so
cad.
Let's
look
at
control
free
africa
file.
E
A
A
All
you
need
to
do
is
keep
the
hot
part
away
through
a
metal
plate,
but
let's
take
a
look
at
it
and
what
it
looks
like
never
been
built,
but
the
concept
is:
is.
F
Before
we
finish
as
well,
I
don't
know
if
we're
gonna
go
back
over
some
of
the
you
know,
basic
things
that
we
need
to
get
done.
I
know
you
mentioned
the
belt
tension
as
one
of
them
in
the
chat
I
put
a
a
link
to
you
know
I
guess
an
option
for
consideration.
I
don't
know
if
it's
something
we
could
rig
up
with
what
we
have
existing
or
if
it's
like
more
of
a
consideration
for
the
park,
design
change,
but
just
wanted
to
get
your
good
thoughts
on
it.
C
B
F
There's
a
belt
tensioner,
like
you,
know,
option
for
like
a
mechanism
yeah
correct
yeah
that
attaches
to
the
frame
versus
the
either
well.
F
Well,
it's
the
green
yeah,
it's
the
there's,
a
nut
that,
I
guess
you
can
use
to.
You
know,
do
the
tensioning
directly
on
the
assembly
and
then
it
yeah
just
puts
the
the
belt
tensioning
on
the
one
stepper
motor
versus
the
idler,
and
it
just
gives
easier
access.
F
A
Well,
the
first
first
comment
would
be:
it
would
be
a
few
days
to
get
something
like
that
yeah.
I
don't
know
if
we
have
the
time
for
that,
but
if
you
think
about
this,
so
just
a
quick
comment
on
if
our
access
is
like
this,
so
that's
the
the
access
piece
and
the
motor
motor
is
like
this.
A
The
motor
piece
goes
like
that,
so
our
axis
is
going
this
way.
A
A
F
There's
another
one
that
has
one:
that's
blue,
that
looked
like
it
actually
was
aluminum
or
something
it
was
shiny.
They
modified
that
a
little
bit.
G
A
A
What's
the
simplest
way,
you
can
go
so
this
we
can
actually
make
even
simple.
Here
I
try
to
say:
okay,
here's
your
little
controller.
So,
let's
strip
this
down
we're
gonna
get
rid
of
all
of
this.
We
don't
need
that
run
the
universal
controller
to
this.
So
get
rid
of
this.
A
A
A
Nothing,
it's
just
that
it's
two
pieces
of
two
by
four
top
and
bottom
metal
plates
a
little
hopper
thing.
That's
it!
So
all
you
got
to
do
is
mount
some
metal
too.
A
A
So
if
this
all
is
metal,
no
problem
by
the
time
you
get
up
here,
it's
kind
of
cool
cooled
off.
This
is
the
hot
part.
You
could
even
do
like
put
a
couple
of
blower
fans
if
we
think
that
that
it's
too
hot
there
are
little
blower
fans,
but
that's
it,
but
so
what's
what's
in
there
you
gotta
couple
the
motor
to
the
plate.
A
You
gotta
have
a
coupler
and
you
gotta
have
the
auger
bit.
The
auger
bit
is
a
hex
shape
shank,
so
you
can
couple
it
geometrically.
It's
not
shown
here
because
that's
a
round
thing.
A
The
trickiest
thing
here
is
how
you
couple
the
motor
to
the
to
the
auger,
because
that's
that's
the
boundary.
That's
the
interface!
It's
a
small
motor.
It's
got
a
half
inch
shaft
and
it's
got
a
keyway
on
it.
So,
ideally,
you'd
have
something.
That's
like
a
half
inch
coupler
to
a
whatever
the
shank
is
what
I
would
actually
do.
A
D
E
A
I
A
Carr
yeah,
that's
in
chicago,
but
they're
like
amazingly
fast.
It's
pretty
decent
place,
so
mount
them
yeah.
We
could
use
that
motor
that
we
have
that
works.
We
know
it
works
so
coupler
to
it.
It's
got
a
keyway
on
it,
so
a
coupler,
half
inch
coupler
and
then
weld
the
socket.
So
we
can
grab
on
to
the
the
hex
of
the
the
one
inch
auger.
So
that's
that's
the
idea
here.
That's
it
people
we've
got
the
universal
controller.
So
all
this
is
like
this
motor
is
like
70
dollars.
A
A
B
A
C
G
A
You
do
you,
gotta
have
a
spooler,
so
that's
this
is
the
easy
part
people.
This
is
easy,
let's
see
so,
let's
paste,
let's
copy
and
paste
this.
This
is
this
is
the
concept
we
can
build.
This
readily.
C
A
A
Yeah
but
all
it
is,
is
you're
you're,
triggering
it
on
and
off.
A
C
A
A
H
E
A
Yeah
power
supply
two
switches:
those
are
just
switches
that
are
actually
speed
control.
Those
are
little
speed
controls
for
the
motor,
the
two
little
motors
here
now
these
little
motors.
I
think
they
can
work
they're
strong
enough
for
like
little
spools.
Like
this,
I
mean
if
we
get
spools
like
this,
if
we
can
start
cranking
out
two
pounds,
spools
that
would
be
cool
and
we
could
even
gear
this
tiny
motor
down
a
little
more.
But
here
like,
as
you
see
it's,
we
got
a
couple
of
proper.
A
A
Contact
wheel
should
probably
print
something
a
little
better
there
yeah
this
3d
printer
has
got
like
duct
tape
on
it,
but
this
is
like
completely
welfare,
but
that's.
This
is
a
lyman
filament
maker,
that's
the
state
of
art
and
open
source,
I'm
not
sure
if
there's
anything
better
for
spoolers
and
winders
right
now,
we
can
take
a
look,
but
I
mean
all
it
is.
A
Is
you
gotta
turn
on
the
spoon
to
wind
it
every
so
often
or
you
can
sit
there
by
hand
and
just
keep
whining
it
for
two
hours
per
spool
you'll
get
paid
ten
dollars
an
hour
because
the
school
is
twenty
dollars,
but
if
we're
actually
spinning
this
out
faster
you'll
be
getting
paid.
20
bucks
an
hour
say
where
the
production
rate
is
actually
two
spools
in
two
hours.
So
every
hour
you
get
twenty
dollars
worth
of
value.
A
Well,
actually,
if
you're
running
a
whole
cluster
of
these,
like
you
got
five
of
these,
that
you're
just
spinning
on
a
on
a
big
roller.
That
that'll
be
the
idea,
get
get
like
four
of
these
things,
a
bank
of
four
of
these,
and
then
you
can
have
a
heavier
motor
and
that
heavier
motor
could
be
run.
A
It
would
actually
be
easy
to
use
the
universal
controller,
the
universal
controller.
That
also
is.
A
B
B
C
Yeah
we
set
it
up
as
a
little
rowing
machine
and
then
we
charge.
C
A
C
A
B
D
I
A
E
A
A
A
A
Yeah,
it's
going
to
get
stuck
in
a
corner,
yeah,
it's
going
to
get
stuck
in
a
corner,
but
if
you
don't
like
that,
put
in
a
put
in
sides,
we
can
put
it
sides.
Yeah
it'll,
be
a
sensible
idea
to
put
in
pieces
of
wood
there,
the
sides
so
that
you
have
that
space.
But
if
you
want
to
be
done
with
it
faster,
you
don't
even
have
to
do
that.
It'll
just
be
there
and
it
will
pollute
your
next
batch
of
whatever
you
have.
A
The
square
corners
will
be
an
issue
in
that
sense.
Yes,.
A
So
what
next?
Well
so
that
will
be
that's
kind
of
what's
laying
ahead.
The
the
torch
torch
is
a
big
one,
but
the
axis
first
axis.
First,
if
we
got
the
axes,
we
got
the
torch.
We
got
the
torch,
we
got
the
shredder
after
the
shredder,
then
it's
extruder
is
easy.
The
winder
is
gonna,
be
the
most
challenging,
but
it's
nothing.
Nothing
particularly
challenging
it's
still.
A
What
we
have
there
was
the
small
on
and
off
switch
logic
which
we
have,
and
that's
all
done
so
if
we
just
replicate
that
nothing
too
too
difficult
about
that,
it's
just
two
little
switches,
little
limit
switches
with
a
long,
long
lever
on
them,
and
we
have
that
part
already
there.
So
we
can
reuse
that
and
you're
just
turning
on
little
little
motors
to
do
the
winder,
but
the
winder.
A
The
only
thing,
I
guess
the
most
to
be
specific
about
the
winder
that
we
can
do
what
what
already
exists
there
driving
the
actual
spool,
but
we
have
to
just
make
the
structure
there
more
solid.
You
saw
the
rubber
band
to
tension.
It
and
it'll
make
that
a
little
better,
but
none
of
this
is
too
particularly
hard
now
to
scale
this
to
industrial
production.
Yeah
you'd
have
to
scale
it
up,
maybe
do
a
bank.
I
do
like
the
bank
idea.
A
Just
have
a
bunch
of
bank,
meaning
like
four
of
these
extruders
have
the
or
even
do
this
same
thing
here
same
chamber
just
make
this
a
longer
thing.
Just
have
four
heads
popping
down
same
hopper,
I
mean
we
should
do
something
like
that.
I
mean
do
one
first
after
we
do
the
first
one
then
put
like
four
heads
on
this,
because
the
parts
are
cheap.
You
know
it's
like
a
hundred
bucks
per
150
or
so
per
the
next
head
and
yeah,
and
that
gets
you
into
like
four
filament
streams.
A
That's
getting
into
something
that
would
be
a
business
now
if
it
does
take
two
two
hours
per
spool
already
I
mean
that's
still
huge
value.
That's
12,
like
you
know,
ten,
a
dozen
spools
a
day,
that's
240
bucks
in
the
market
so
per
day.
If
it's
running
automated,
then
you're
not
even
babysitting
it
and.
C
A
A
F
E
C
A
Yeah
exactly
that
determines
what
is
technically
technically
known
as
children,
it's
called
filament
and
if
you
have,
you
can
get
away
with
a
lot
like
if
you've
got
a
basic
formula,
once
you
start
trying
to
print
like
engineered
material,
you
have
to
know
exactly
what
you
need,
but
for
non-structural
or
just
both
printing
aspects
like
say
you
want
to
print
your
foundation,
forms
or
plastic
lumber.
A
It
could
be
a
mix
of
various
things
they
have
to
be
compatible.
Like
some
plastics,
don't
stick
to
one
another.
Others
do
so,
there's
a
whole
realm
of
thousands
of
different
formulas
that
that
are
project
onto
their
own,
but
with
basic
principles.
You
can
mix
there's
a
lot
of
misability
that
that
is
allowed
and
some
things
that
just
don't.
A
If
they
don't,
you
might
have,
maybe
that's
a
feature
like
say
you
print
a
skin
of
one
material
and
in
the
fill
of
another
that
doesn't
stick
to
it.
I
don't
know
whatever,
but
there's
yeah.
It's
there's
a
lot
of
flexibility
there
to
what
you
can
do.
A
A
B
A
To
a
basic
level
like
and
depends
what
percentage
like
if
you've
got
say
primarily
we're
like
using
up,
I
don't
know
plastic
cups.
We've
got
a
little
bit
of
this
polyethylene
with
it.
If
it's
a
small
part,
you
can,
you
know,
depends
what
percentage
it
is,
but
in
an
ideal
situation
you
yeah,
you
work
out
your
basic
process.
It
will
be
definite
process.
Engineering,
like
you,
gotta,
work
out
what
works,
but
once
you
get
it,
I
think
it'll
be
pretty.
B
A
But
I
mean
there's
definitely
bulk
sources
of
uniform
plastic
like,
for
example,
all
the
you
know,
the
pvc
plastic
that
we
have
here
that
are
scraps
from
plumbing
projects
or
whatever
there's
you
know.
We
got
a
whole
bucket
of
pla
already
and
stuff
like
that.
It's
there's
plenty
of
resource
on
that,
so
we're
not
showing
a
resource
on
that.
A
It's
actually
enough
for
about
100
about
10
million
houses
if
they
were
all
plastic
per
year
from
the
global
supply
chain
of
plastic
that
goes
to
the
trash,
not
recycled,
10
million
houses.
So
it's
like,
I
thought
it
would
be
much
lower,
but
that's
actually
quite
a
bit
of
houses.
You
can
build
in
terms
of
like
if
you
make
plastic,
lumber
or
wood
infill
plastic
lumber,
which
kind
of
smells
like
wood.
Even
you
know
just
plastic
plastic
with
like
wood
powder
or
tiny
pieces
of
wood.
That's
that's.
A
Yeah
you'd
mix
it
all
up
and
and
extrude
it.
So
you
can
do
all
kinds
of
additives.
You
can
add.
If
you
add
enough
metal
powder,
you're,
printing,
you
can
print
metal
objects
which
then
you
have
to
burn
out,
and
then
you
get
a
100
metal
object.
That's
another
way
to
go
and
if
you
guys
have
heard
about
that
metal
filaments.
A
100
once
you
burn
out
the
other
stuff
so
there's
but
inside
in
the
plastic,
it
would
be
probably
like
about
30
percent
or
30
to
70
percent.
A
So
you
can
do
that.
But
that's
there's
companies
that
do
that
and
that's
actually
awesome
area
for
r
d,
like
how
do
you
work
out,
there's
a
thing
called
metal
injection
molding?
How
do
they
do
that?
What
is
that?
That's
metal
powder
in
a
plastic
matrix
and
then
you
burn
out
the
plastic
and
you
get
a
hundred
percent
kind
of
like
a
centered
metal
structure.
So
it's
not
like
the
the
great
strength
it
would
be
like
a
centered,
centered,
strong
yeah,
you
got
porosity
but
yeah
that
that
works.
A
E
A
A
A
A
Put
metal
in
a
ball
mill,
it
just
crumbles
up
ball
mill
is
a
cylinder
with
big
balls
that
just
keeps
smashing
thing
into
nanopart
nanoparticle
sizes
talking
about
nanometers
scale
particles.
A
This
is
nanotech,
that's
advanced.
This
is
advanced
stuff,
but
it's
relatively
easy
to
get
like
for
the
stainless
like.
I
guess
you
can
put
stainless
steel
inside
a
regular
ball
mill,
but
for
other
things
that
rust,
because
the
surface
air
is
so
huge,
it'll,
just
rust
or
oxidize.
So
you
don't
have
that
pure
powder
anymore.
So
you
probably
need
an
inert
chamber
to
do
this
with
most
metals,
but
that's
a
well-established
technology.
A
A
Do
the
axis,
but
there's
more
like
what
about
the
okay,
so
there's
it
would
be
the
spool
holder.
There
will
be
parts
we
can
print
out
for
the
top
like
we
have
the
the
big
rod
on
top.
We
can
put
another
rod
across
that
we
can
print
out
a
little
connector
like
the
small
spool
holder
that
we
have.
I
don't
know
if
you
guys
the
spool
holder.
A
Oh
look
at
say:
d3d.
A
A
Guide,
we
want
to
probably
like
these.
I
don't
think
what
we
have
here,
which
are
these
things
they're
like
way
too
massive.
We
can
redesign
a
very
simple
version
of
that.
Basically
things
that
snap
into
each
other
and
they
can
rotate
that's
a
simple
redesign
thing.
I
was
actually
thinking
for
this.
Just
use
a
screw,
since
this
is
kind
of
hard
to
print,
because
those
those
pegs
they're
kind
of
against
gravity.
A
A
A
Okay
and
then
make
these
things
longer,
make
them
like
three
inches
long,
so
we
only
need
so
many
of
them.
I
mean
the
area.
We're
spending
is
pretty
huge,
so
if
you
make
them
like
two
or
three
inches
per
and
we
get
the
whole
cluster
printers
printing,
that's
where
you'd
need,
like
a
cluster
that'll,
be
useful
to
run
all
the
printers
on
it
to
make
these
things
so
there's
that
what
else
is
missing
from
completion
on
there?
So
there's
the
bed.
I
A
That's
good
anything
else
missing
from
getting
all
the
axes,
so
there's
the
one
one
pulley,
that's
not
not
attached
the
belt.
Tensioning
is
something
to
do
we're
getting
so
right
now
we're
getting.
A
We're
doing
the
counterweight
so
do
we
have
the
four
pieces
printing
for
the
the
idler
pieces.
It
would
be.
A
Okay,
we'll
see
okay,
so
that's
an
easy
solution
for
that
and
get
a
piece
of
steel
like
do
like
a
one
by
one
by
six
little
slab
of
steel
like
20
pounds
on
each
side
or
40
pounds
on
each
side.

So
right
now
the
way
the
belts
were.
We
were
actually
getting
25
like
seven
to
17,
without
traditional
tensioning
right
we're
getting
17
per
motor
so
times
four
is
64
pounds
of
uplift
with
the
tension
that
we
already
have.
We
pressed
harder
on
the
tension
that
we
were
getting
like
27
pounds
per
motor.
A
I
A
I
could
who
wants
to
take
a
stab
at
redesigning
this
thing.
I
I
can
do
that
like
real,
quick.

The
big
big
yeah
you
can
hang
this
and
it'll
be
good
enough
for
now.
