A
If
you
go
to
photos
or
obviously
filament
extruder,
I
actually
go
into
data
collection.
There's
temperature
records
so
just
posted
that,
but
this
is
the
current
state
we've
got,
is
some
issues
like
we're.
We've
got
two
bands
heating
the
extruder
right
now
insulated.
Through
this
little
shroud,
we've
got
one
band
towards
the
bottom
by
the
by
the
nozzle
and
one
towards
a
little
higher.
A
A
A
A
It
doesn't
yeah,
it
doesn't
reflect
what
is
true,
because
we
can't
see
the
temporal
evolution
of
this
here.
We
see
the
hot
glow
which
implies.
I
mean
glow,
starts
at
like
900
f,
so
that's
super
hot
in
this
example
here
this
is
when
this
reflects
some
of
the
the
jumps
that
we
have
like
the
set
point
of
230
at
the
bottom.
A
After
waiting,
I
don't
know
like
five
minutes.
This
was
five
minutes
or
so
or
ten
minutes.
A
A
A
To
be
expected,
that's
called
hysteresis
over
time
the
logic
of
the
it's
called
the
pid
algorithm,
proportional,
integral
differential
controller
system.
That's
what
these
little
controllers
have
built
into
them.
I
don't
know
about
the
exact
details
of
what
parameters
are
using
within
that,
but
if
the
algorithms
are
working,
you
should
stabilize
to
some
known
temperatures
as
set
now.
A
B
There
seems
to
be
a
lot
of
heat
transfer
from
the
bottom
heating
element
to
the
top
thermometer,
so
our
readings
is
based
on
what
the
thermometer
is
sensing
and
that,
but
the
heat
might
displace
differently
throughout
the
machine.
It
might
be
harder
at
the
bottom,
because
we
have
a
bunch
of
threaded
bushings
that,
like
a
babushka
doll,
just
leads
down
to
the
nozzle,
we
might
have
accurate
temperature
inside
it's
just
just.
The
reading
gives
us
226
for
another.
A
Yeah,
so
what
causes
a
higher
temperature
in
one
lower
temperature
on
another?
What's
the
difference
between
the
two
ones,
I'm
seeing
difference
in
amount
of
insulation
they
have
if
the
tip
is
not
covered
and
the
and
the
upper
heater
element
is
known.
Clearly,
the
thermometer
is.
A
B
B
A
Be
careful
about
location
of
pay,
attention
to
location
of
heater
element
versus
sensor.
A
B
D
Maybe
we
just
need
to
use
a
different
measuring
device,
so
we're
measuring
the
temperature
inside
the
tube
rather
than.
B
B
B
B
B
D
I
mean
so
and
that's
there.
I
see
that
there
could
be
like
two
approaches.
One
is
we
use
an
equation
to
determine
the
temperature
internally
of
the
pipe
from
a
measurement
on
the
perimeter
and
two
so
that
we
use
like
a
attempted,
some
sort
of
internal
temperature
measuring
device,
otherwise
we're
just
getting
the
temperature
on
the
outside.
D
D
B
C
A
So
if
you
have
insulation
with
any
kind
of
r
value,
our
value
refers
to
how
much
you're
slowing
slowing
the
heat
transfer
down
if
you've
got
pretty
much
immediate
contact,
immediate
transfer
through
metal
as
long
as
you're
insulating
it
outside
temperature
should
be
inside
temperature
on
the
metal.
It's
fast
one
side
of
the
one
side
of
the
metal
versus
the
other,
like
a
pot
on
the
stove.
A
If
you
put
a
flame
to
it,
it
will
get
pretty
hot
on
the
other
side,
pretty
quickly
pending
the
actual
sea
of
electrons,
the
the
conduction
of
the
metal
for
less
conducting
things
like
stone
or
like
rock
wool
or
brick.
It
takes
a
bit
of
time,
but
metals
are
quite
conducting.
So
if
you're
insulating,
you
can
make
a
fair
assumption
that
the
temperature
on
the
outside
is
going
to
be
quite
close
to
the
inside
temperature.
A
How
close
do
we
need
to
be
now?
We
need
to
be
like
within,
like
five
or
ten.
We
need
to
be
within
the
safe
melting
temperature
of
any
plastic.
So
since,
if
we've
got
say
abs,
you
know
say
230
or
so
typically
the
range
before
you
start
breaking
down,
the
plastic
is
going
to
be
within.
A
A
A
You
can
have
different
kinds
of
abs
formulations,
depending
on
how
the
molecules
are
actually
lined
up
how
the
blocks
within
abs
plastic
are
actually
composed,
like
butadiene
styrene
block
polymer
is
that's,
I
believe
what
what
that's
about
so
it's
like
the
size
of
those
blocks
determines
the
specific
properties,
but
you
see
the
huge
range
like
190
to
270..
A
Well,
in
our
printers
we
typically
went
around
like
230
or
240
for
abs,
it's
probably
a
good
temperature,
but
it's
like
plus
minus
10..
That's
perfectly
fine.
What
you
want
to
do
is
prevent
frying
this
stuff
like
we
are
right
now
by
going
way
above
those
points
which
we
clearly
did
so
here
we
want
to
stay
within
a
few
degrees
for
optimal
melting,
I
mean
so
the
less
breakdown
of
the
material
you
get.
That
means
like
breakdown,
means
crowded
building
up
in
the
inside
the
natural
filament
maker.
A
A
What's
to
be
said,
so,
as
far
as
insulation,
like
put
a
little
background
there,
the
nozzle,
we
should
probably
hang
the
insulation
down
even
like
a
little
bit
lower
than
the
nozzle,
but
definitely
around
the
nozzle
and
possibly
a
little
bit.
A
I
have
this
thing
kind
of
making
this
cavity
here,
where
you're
insulating
as
much
as
you
can
all
you
need.
I
mean
you
want
that
as
much
as
possible,
so
that
you're
not
leaking
out.
The
idea
is
the
metal
and
air
you're
radiating
your
rating
temperature
away
like
through
radiation
like
radiant
heat,
it's
not
not
even
conduction
or
convection,
which
is
upward,
conv
induction
in
air.
A
It's
just
plain
radiation,
like
sigma
t
to
the
fourth
style
in
the
physics
where
it's
I
don't
understand,
that's
physics,
but
there's
a
formula
of
how
much
radiation
you
get,
and
it
varies
as
the
fourth
fourth
degree
of
temperature.
A
In
other
words,
once
you
reach
high
temperatures
like
once,
you
start
glowing,
a
lot
of
the
heat
transfer
is
through
plane
radiation.
That's
how
radiant
heaters
work
like
a
like.
A
fire
like
in
a
fireplace
you'll
see
that
not
just
by
the
conduction
of
the
the
heat
through
the
air
you're
getting
that
radiation
like
the
sun's
radiation
that
burns
your
skin
it's
radiation,
it's
not
like
you
get
you're,
conducting
all
these
molecules
from
the
sun.
A
A
A
That
means
at
a
certain
point,
the
majority
of
the
heat
loss
goes
to
radiation,
but
anyway,
wherever
you're
not
covered,
the
radiation
is
in
full
effect,
you're
fully
radiating
it.
What
happens?
Well,
the
radiation
happens
all
over
that
heater
element,
but
if
it
goes
into
the
insulation,
it's
trapped,
it
comes
back.
It's
going
to
bounce
back.
So
that's
why
the
insulation
is
critical.
Here,
you
want
all
that
heat
to
be
kept
in
and
that's
how
you'll
equalize
the
temperature.
Otherwise
you
can
clearly
have
differences
in
temperature
like
we're.
A
A
The
rest
of
it
is
trapped
within
we've
got
this
pipe
insulation.
We've
been
using
or
you
can
use
fiberglass.
A
If
we're
keeping
that
temperature
in,
we
should
get
to
the
point
where
we
set
it
at
say,
230
and
you
literally
get
an
ooze
out
without
even
running
the
motor
yeah.
Have
we
seen
that
a
little
bit
or
not
really.
A
Yeah
so
yeah
we.
B
Gotta
say
it
flows
quite
nicely
like
when
it
when
it
does
have
that
low
interval
of
good
temperature.
A
A
A
Yeah,
it's
a
it's
a
rubber,
it's
a
rubbery
material.
So
actually
that's
pretty
cool
it'll
get
you
well
I'll,
get
you
rubber,
filament's
heart
kind
of
hard
rubber
material,
but
we
know
I
know
a
bag.
I
know
which
bag.
A
That
is
so
we
can
use
that
with
the
the
other
thing
about
if
it's
pt
or
ptg
or
p-t
yeah,
whichever
that
is
p-e-t,
is
actually
highly
hydroscopic,
meaning
absorbs
a
lot
of
moisture,
so
it'll
be
harder
to
work
with,
and
maybe
that's
the
thing
that's
preventing
us
from
succeeding,
like
maybe
there's
bubbles
here
and
we're
bubbling
stuff
and
not
really
filling
the
nozzle.
A
So
you
get
continuity,
that's
the
thing,
so
we
definitely
want
to
go
as
slow
as
possible
on
the
auger
once
we're
auguring
or
maybe
even
like
turn
the
auger
auger
on
and
off,
maybe
even
in
like
pulse
it
in
one
second
on
one,
second
off
or
well,
because
if,
if
we're
pushing
too
hard,
we
gotta
control
the
idea
that
we're
not
squeezing
material
out
too
fast,
so
we're
actually
emptying
the
chamber.
A
If
not
enough
is
melting,
because
now
we
have
this
one
inch
one
inch
auger
and
that
motor
is
pretty
relatively
fast
there.
So
it's
just
a
consideration.
We
have
to
be
careful
that
if
we're
altering
full
force
that
we're
not
emptying
the
chamber
and
creating
air
spots
in
there,
where
you
don't
have
enough
heating,
so
how
do
you
counteract
that?
Well,
smaller
nozzle
hole
or
what.
A
C
B
A
We
can
actually
go
at
maybe
have
two
options:
one
and
twelve
volts
one
and
twenty
four,
but
we
don't
know
it's
just
speculating
like.
What's
what's
the
real
block
now
in
a
in
the
precious
plastic
system
they
do
have.
I
mentioned
that
set
screw.
I
did
at
the
tip
which
allows
you
to
control
how
much
you're
actually
blocking
the
orifice.
So
as
far
as
how
much
will
escape
out
the
nozzle,
we
can
rig
up
something
like
that.
A
B
A
So
yeah
there's
different
things
we
can
play,
but
the
first
thing
stabilize
the
temperature
and
see
see
what
happens
when
we
when
we
turn
on
the
motor.
What
kind
of
flow
rate
I
mean?
Is
it
a
thing
that
we
observe
that
as
soon
as
we
turn
on
the
motor
it
just
starts
shooting
out
wildly
compared
to
when
you
just
when
you're
just
heating
it
so
playing
around?
With
that
a
little
bit.
A
Wild
ejection,
so
so
things
to
look
for
so
like
let's
talk
at
talk
about
like
conditions,
I
mean
test
procedures
biggest
one
is
the
flow
rate,
I'm
sure
we
can
get
the
temperature
stabilized.
We
can,
let's
see
heat
stabilization
and
plug
yes
before
we
go
into
the
ejection
temperature
determined
by
the
motor
where
so,
where
is
our
our
band
heater
versus
the
sensor?
Right
now,.
B
So
the
top
white
wrap,
wrap
thermistor
or
the
the
lower
wrap
wrap
thermistor,
which
is
the
second,
the
third
heater
from
the
bottom.
That
one
has
been
moved
to
the
tip
of
the
bottom,
so
I've
I've
moved
that
around
to
probe
it
basically,
so
it's
not
mounted
like
it
is
there
and
what
I
want
to
try
to
do.
I
try
to
change.
Color
fills
very
clearly.
A
All
right,
so
what
would
you
suggest.
B
Try
get
stable
temperature
with
changing
the
temperature
settings.
The
the
insulation
around
also
see
if
I
can
fit
the
heat,
the
lowest
heating
element
even
lower,
ideally
just
around
the
nozzle.
A
Yeah,
why
not
certainly
that
that
should
be
the
case,
because
you
want
it
to
be
exactly
where
you're
extruding
yeah
that'd
be
a
good
idea,
because
otherwise
the
nozzle
like,
if
that
heater
element
is
a
little
bit
above
whatever
is
exposed
on
the
nozzle
you're,
just
dropping
temperature
right
there.
That's
that's
all
that's
happening
and
temperature
above
that
may
be
higher,
but
you
want
the
temperature
to
be
good
at
the
nozzle
because
you
don't
want
it
to
solidify
you
want
it
to
be
the
hottest
point
just
like
in
a
in
a
3d
printer.
A
B
B
Is
that
the
last
bottom
part
is
tapering
off
significantly,
so
the
circumference
is
smaller
than
the
heating
elements
are
made.
For
so
I'm
wondering.
Is
there
a
filler
material
that
conducts
really
well
aluminum
foil.
A
A
A
A
B
A
Like
if
you
had
the
thermal
analysis
software,
this
is
not
that
easy.
C
C
C
A
B
D
B
C
B
D
D
A
C
A
A
A
Let's
take
a
look
at
the
motor
again
real,
quick
to
see
what
what
the
specs
are
on
that.
A
The
current
will
rise
at
that
point,
so
it
can
rise
up
to
11,
but
normally
when
it
operates,
it's
a
couple
of
amps.
If
it's
a
30
watt
motor,
yes
2
amps
at
24,
means
you're
using
like
50
50
watts,
so
this
motor
is
like
0.6
.6
efficient
altogether,
so
you
got
30
watt
output.
You
got
about
50
watts
in
in
stall
conditions.
You
got
a
lot.
A
You
got
like
200
watts,
10
x,
24
like
over
200
watts,
but
if
we
could
control
2.2
amps,
can
we
do
that
with
the
universal
controller
by
turning
it
on
and
off
rapidly?
We
do
have
that
capacity.
So
what's
the
limit
of
the
well?
Actually,
I
did
get
some
dc.
Okay.
We
do
have
some
capacity
in
that
we
do
have
some
dc
to
dc.
A
Since
we
talked
before
I
got
dc
to
dc
solid
state
relays,
you
can
turn
them
on
on
and
off,
like
probably
up
to
like
10
times
a
second.
Maybe
if
we
wanted
to,
we
could
actually
pulse
the
solid
state
relays
to
control
the
motor
like
bang,
bang,
it's
called
mode
like
you're,
just
turning
it
on
and
off,
but
not
super
fast
in
a
pulse
width.
Modulation
range
of
like
kilohertz,
like
super
fast
that
you
don't
even
see
it.
A
So
we
have
solid
state
relays
that
can
do
the
rapid
on
off,
as
in
a
few
hertz,
meaning
like
up
to
like
10
per
second.
So,
yes,
potentially
that
could
do
it
for
the
on
board.
Transistors
they're
rated.
A
A
A
You
do
a
partial
value
like
if
you
want
the
motor
to
run
at
half
speed,
you
would
turn
that
value
to
say
128
and
you're
running
at
half
speed,
but
what
it's
actually
doing
is
rapidly
turning
it
on
and
off
50
duty
cycle.
So
we
have
that
capacity
as
well.
So
we've
got
a
bunch
of
ways
to
control
this
motor.
A
B
A
A
Shake
yes,
with
a
real,
solid
state
relay
dc
to
dc
so
dc
to
dc
solid
state
relay.
What's
that
look
like
it's
the
same
thing
except
they
look,
they
have
a
dd
at
the
end
there
dd,
meaning
you
got
input
in
dc
output
in
dc,
so
5
to
60
dc.
A
But
yes,
we've
got
a
couple
of
these,
so
we
can
do
this
and
what's
the,
how
fast,
can
you
switch
this?
Let's
google,
that
how
fast
can
you
switch
a
solid
state
relay.
A
Yes,
with
s,
solid
state
dc
dc
relay
can
switch
120
hertz,
it's
really
determined
by
the
zero
crossing
of
a
sine
wave,
which
is
the
current
that
comes
out
of
the
wall,
which
is
twice
per
it's
60
hertz,
but
it
crosses
zero
twice
per
cycle.
So
that's
why
the
120.
C
A
About
so,
let's
make
a
note
of
that:
let's
put
a
link
to
the
solid
state
relay.
B
A
Power
dc
dc
relays
there.
A
D,
a
as
in
for
dc
to
ac.
You
would
think
that
they'd
want
to
switch
like.
Why
can't
you,
if
you
can
switch
alternating
current?
Why
can't
you
do
direct
current,
it's
kind
of
weird,
but
the
way
these
work,
you
can't
you
gotta,
have
a
special
one.
A
B
A
Yeah
just
like
we
are
handling
power
right
now
from
for
the
heaters,
we
can
be
handling
power
to
the
motor
and
actually
switching
the
motor
on
and
off.
In
fact,
with
the
dc
to
dc
heaters,
the
way
we
can
be
switching
them,
we
can
vary
that
through
the
universal
controller,
there's
different
algorithms.
We
can
use
for
how
the
actual
heating
is
applied
from
just
the
on
off
on
slow
times
time
scales.
A
You
can
set
that
completely
from
how
many
ever
hurts
you
want
from
like
switch
it
once
every
second
ten
times
a
hundred
thousand
hundreds
of
thousand
times
per
second.
So
we
have
that
ability
to
control
the
speed
through
this
universal
controller,
but.
A
A
A
Very
augur.
Speed
through
different
ways,
use
a
throttle
screw.
That's
what
I
mentioned
block
off
the
nozzle
aperture.
A
A
A
Yeah,
you
can
also
the
thing
we
want
to
get
away
from
is
I
mean
we
do
have
the
nice
round
pellets,
but
the
goal
here
was
see
the
nice
round
pellets.
They
kind
of
flow
down
the
throat
of
this
heater
barrel,
more
easily,
they're,
smoother
right
they're.
Like
little
balls.
A
A
I
mean
you
can
heat
the
more
you,
the
hotter,
the
well
melt,
the
more
well
melted,
the
the
plastic
at
the
right
temperature,
the
more
it's
going
to
flow,
so
the
temperature,
it
kind
of
you
can
say.
That's
it's
not
exactly
extruder
push,
but
it
is
the
rate
of
how
fast
you're
extruding
that
will
be
determined
by
the
specific
temperature
you're
working
at
so
the
higher
the
temperature.
It
should
flow
more
but
the
higher
it
is
you're
going
to
start
burning
stuff
and
it
will
start
flowing
less.
A
So
you'd
want
to
go
at
the
highest
temperature
to
get
the
best
melt,
but
you
want
to
keep
it
lower
low
enough.
So
you're
not
actually
caramelizing
this
and
turning
into
black
nasty
stuff.
So,
but
we
can
say
that
temperature.
A
Control
and
there
could
be
notions
of
like
the
pulsed
purses,
so
there
are
notions
of
pulsed
versus
continuous
operation.
A
You
can
pulse
the
temperature,
certainly
you
can
you
can
just
get
it
up
turn
it
on
turn
it
off.
You
can
pulse
it
to
make
it
rise
gradually.
A
Those
are
the
control
methods
that
the
control
algorithms
use
within
the
software,
whether
it's
the
universal
controller
or
the
pid
controller
that
we
use-
and
you
can
also
do,
as
I
mentioned,
for
the
motor
you
can
keep
it
on
the
whole
time
at
partial
power
or
you
can
control
it
by
turning
it
on
or
off
in
discrete
units.
So
those
are
the
kinds
of
things
we
have
control
over
for
both
motor
and
heat
heaters
and
the
number
of
heaters,
but
start
with
start
with
one
heater.
A
Okay,
so
we
kind
of
covered
how
you
control
the
push
the
end
plug.
We
talked
about
start
with.
One
heater
element
vary
the
power
out
power
to
the
heater
you.
The
only
way
you
can
vary
the
power
to
the
heater
is
by
using
a
different
band
heater.
We
have,
I
think
we
have
a
couple
of
types
of
band
here.
I
didn't
really
look
at
do.
Did
you
notice
what
power
it
is
like
200
watts.
A
So
that's
that's
something
we
do
have
a
couple
of
different
heaters:
the
set
point
temperature.
Well,
what
does
the
power
of
the
heater
determine?
Does
it
determine
the
max
temperature?
A
It
does
determine
how
fast
you're
getting
to
that,
like
you
just
blow
out
through
with
high
power
you
blow
out
to
the
max
temperature
quickly,
if
it's
higher
power
than
not
you'd
be
potentially
burning
the
stuff
faster.
A
We
can
actually
so
in
this
yeah,
okay,
so
actually
just
to
cover.
We
can
vary
the
power
to
the
heater.
If
we
do
a
simple
turn
on
oh
yeah,
okay,
this
is
actually
this
may
be
useful.
We
can
either
turn
it
on
and
it's
on
just
bam
full
on,
but
all
those
d8
through
d10s
have
the
pulse
width
modulation,
setting
the
idea
that
you
can
switch
them
rapidly.
That's
internal
to
the
board.
A
More
incremental,
indeed
so
yeah
so
here
may
be
the
case
like
we
can't
be
shy
about
like
okay,
if
we
have
to
turn
the
machine
on
and
maybe
walk
away
and
then
come
back
half
an
hour
later,
that
might
be
the
the
thing
to
do
like
I
remember
the
vladmin
extruder.
We
had
to
wait
for
it
to
heat
up
until
the
temperature
stabilized.
It
would
go
through
a
few
of
these.
These.
D
A
That's
just
part
of
the
game.
The
startup
time
may
be
an
issue,
and
that's
the
kind
of
thing
that
after
we
learn
what
happens
really
well,
then
we
can
say:
oh
okay,
now
we're
gonna
when
we
turn
it
on
we're
gonna.
Do
it
like
in
this
algorithm
we're
gonna
like
turn
it
to
fifty
percent
power,
we're
gonna
turn
it
off
for
a
little
bit
and
so
forth,
like
whatever
we
decide,
makes
it
approach
the
correct
temperature
the
fastest.
A
It
might
be
just
all
the
algorithms
already
in
the
system
already
achieved
that,
but
no
there's
always
fine
tuning.
You
can
always
fine-tune
and
and
do
things
like.
Oh
what
happens
when
you
do
now
two
heaters
or,
however,
you
know
you,
it's
always
an
interplay
of
how
you
how
fine,
how
much
you
fine-tune
it
to
how
much
you
want
to
mess
with
it.
You
can
have
high
power,
but
you
need
to
find
your
control.
You
can
have
lower
power
in
there
and
you
don't
need
as
much
tight
control,
because
everything
is
slower.
A
D
A
It's
not
just
this
one
molecule!
No,
and
if
you
have
one
kind
of
a
tpu,
if
it's
a
block,
copolymer
thingy,
it's
made
of
blocks
of
repeating
units,
the
chemists
can
vary
the
size
of
those
blocks
or
how
many
of
each
kind
of
block
they
use.
So
I
mean
in
general,
with
plastic
chemistry.
You've
got
infinite
ranges
of
possibilities
for
the
actual
chemical
composition.
Therefore,
the
properties
will
be
a
little
different,
depending
on
which
you're
working
with.
A
Yeah
barrel
temperature,
so
like
this,
I
guess
goes
for.
Like
injection
molding,
oh
yeah,
you
can
find
nozzle
temperature
180
to
220
front
center
rear
okay,
so
you've
got
some
algorithms
for,
for
example,
in
a
commercial
extruder.
That's
what
they
do.
They've
got
apparently
here
four
zones
of
heating,
so
that's
kind
of
when
you
get
to
the
professional
thing.
So
you
kind
of
have
this
idea
of
preheat
and
then
getting
warmer
and
warmer
until
you're
melting
at
the
nozzle.
A
A
A
So
you
have
to
overcome
all
that.
You
have
to
have
enough
residence
time
that
this
just
melts
yeah
in
that
short
barrel,
but.
B
It
shouldn't
and
like,
given
that
we
have
the
heat
hottest
point
at
the
lowest
at
the
lowest,
the
hottest
temperature
at
the
lowest
point
of
the
nozzle.
The
flow
rate
is
going
to
be
dictated
about
from
how
easy
that
falls
down
closer
right,
that's
going
to
dictate
how
anything
else
moves
too,
because
looking
at
it
before
I
mean
we
didn't,
have
a
consistent,
long
run,
but
the
extrusion
speed
seems
to
be
it
might
just
work.
A
Yes,
yeah,
it
may
just
all
come
out
in
a
wash.
We
do
also
have
another
auger,
which
is
slightly
slightly
smaller,
like
when
we
tested
it
was
just
slightly
more
loose,
so
have
less
push,
and
maybe
that's
what
we
actually
need
a
little
less
push
than
more.
You
know.
So
that's
if
we
talk
about
the
film
and
push
force.
A
A
Well,
actually,
the
the
thing
to
consider
is:
we've
got
that
one
inch
barrel.
It
could
be
that
we
reduce
it
to
half
inch
and
use
only
like
use
a
longer
heater
barrel.
That's
here's
that
longer
heater
barrel,
just
with
heater
elements
and
then
the
bottom
part,
which
has
got
the
auger
and
even
like
a
half
inch
auger,
possibly,
but
I
don't
I,
the
idea
of
the
one.
C
A
You
don't
have
any
really
any
push
where
the
there
is
no
flutes
on
the
auger
yeah,
but
those
are
kind
of
things,
because
the
thing
that
I
can
observe
right
now
I
mean
that
barrel
is
actually
pretty
short
for
the
the
one-inch
one-inch
auger
like
it
seems
like
all
that
mass
it's
pretty
rapid
to
to
get
that
all
heated
up
and
because
of
the
volume
of
a
one
inch
I
mean.
B
A
A
Yeah
they're
hype
like
like
the
one
you
see
on
even
on
precious
plastic.
You
see
they've
got
this
big
motor,
that's
way
geared
down
to
drive
their
auger,
so
they're,
using
it
they're
doing
it.
What
you
need
to
do
in
things
like
you
need
that
force
for
injection
molding.
We
don't
need
it
here,
but
yes,
friction
is,
is
real.
A
There's
did
you
know
that
there's
a
thing
called
friction
stir
welding.
C
A
A
A
B
Is
that
to
not
get
any
skewing
in
the
metal
due
to
the
heat?
No,
it
still
produces
heat.
What
is
friction.
A
A
The
pro
is
that
that,
because
you
don't
have
the
extreme
heat
of
a
spark
which
is
like
millions,
I
think
it's
like
million
degrees,
it's
like
really
hot,
but
it
actually
makes
the
metal
much
stronger
because
it
doesn't
have
that
kind
of
weakening
due
to
the
the
crystallization
that's
associated
with
welding,
yeah
yeah.
A
So
yeah
there's,
that's
that's
like
the
high
tech
for
like
precision,
vessels
and
stuff
that
you
don't
want
to
blow
up
and
stuff
space
age.
Tech
anyway
use
different
august
yeah,
that's
a
that's
a
possibility
there.
If
we
have
to
extend
the
auger
shaft
well,
possibly
take
that
auger
like
if
we
find
that
we're
just
not
getting
them
out.
A
We
can't
get
the
motor
slow
enough.
No,
we
got
to
get
the
motor
slow
enough
or
turn
it
off
to
make
sure
that
we've
got
the
full
barrel
fill,
but
we
might
find
that
at
the
end.
One
thing
I
could
see
is
that,
because
we're
slowing
down
and
allowing
the
heat
to
properly
happen,
like
the
extrusion
rate,
is
actually
ends
up
being
really
low,
possibly
in
which
case
the
solution
would
be
to
extend
your
heat
zone
lengthen.
The
barrel,
in
which
case
we'd,
have
to
extend
the
actual
auger
bit.
C
A
A
B
A
A
A
Yeah,
okay,
so
what
are
the
priorities?
So
actually,
when
we
go
down
there,
we
can
go
through
and
look
at
all
the
parts
that
we
have.
Because
then
also
is
the
controller
of
the
wine,
the
winder
and
the
pooler
and
winder.
We
have
those
parts
there,
so
we
can
take
a
look
at
what
we've
got
yeah.
A
Yep
take
some
data.
If
you
go
to
so
there's
a
placeholder
you
can
find
on
my
log,
but
it's
the
oc,
filament
extruder.
A
A
D
B
So
there's
four
thermometers,
two
from
those
two,
several
controllers
and
two
for
the
red
crop,
but
only
the
separate
controllers
are
connected
to
the
ssr.
This
whole
state
wheels,
so
only
the
separate
external
controllers
are
actually
affecting
the
wattage
that
comes
into.
D
To
capture
the
data
and
then
make
a
graph
or
like
plot
something
in
python,
because,
like
here's,
the
temperature
over
time.
A
D
A
Well,
we
have
the
temperature
reading
and
activation
of
the
various
pins
like
d8d9d10,
which
we
were
we're
going
to
use
for
controlling
the
elements.
So
that
part
is
useful,
but
beyond
that
to
actually
capture
the
data
yeah
that
that's
an
addition
that
could
be.
B
It
would
be
really
interesting
to
have
those
curves
but
to
incorporate
that
into
recreate.
As
like
a
algorithm-based
solution,
I
like
to
make
it
the
hysteresis
to
sort
of
overshooting
and
I'm
shooting
to
even
that
out
through
the
red
crap.
I
don't
understand
how
we
can
do
it,
because
that's
more
like
firmware.
A
There's
so
within
within
a
temperature
control
algorithms.
In
configuration
h,
you
can
actually
set
some
of
the
parameters
for
how.
B
Yeah
and
that's
part
of
the
firmware,
but
not
the
g
code,
so
that
we
can
use
feedback,
it's
just
relying
on
the
model
firmware
right
yeah.
So
if
you
can
find
a
way
to
capture
the
data
with
the
model,
firmware
don't
want
it,
it's
probably
better,
and
then
we
assign
these
thermometer
as
if
it's
the
bed
eater
or
something
and
then
make
that
reading
turn
on
and
off.
D
A
D
B
A
Yeah
you
can,
but
it's
like
a
pcb
yeah,
I
mean,
but
it's
kind
of
for
keycard,
it's
kind
of
a
crude
representation
of
it,
because
you
it's
kind
of
hard
to
represent
all
those
elements
you
can.
But
it's
a
basic
diagram,
it's
very
useful
for
when
you
have
okay,
here's
a
pcb
for
the
reprap
controller,
but
once
you
get
a
bunch
of
things
interconnected,
that's
more
like
diagramming
software.
A
A
I
mean
fritzing
fritzing
is
useful
because
it's
low
entry
level
curve
for
usage
you
basically
like,
drag
and
drop
stuff
in
there.
It's
got
a
lot
of
library
parts
but
like
in
our
workflow,
you
know
we'll
say
working
on
our
dock.
It's
like
well,
you
know
we're
just
ending
up
drawing
a
lot
of
stuff
in
this
docs,
but
it
would
be
useful
to
to
pull
out
all
those
part
libraries
from
fritzing,
because
it's
got
symbols
and
graphics
for
all
the
different
elements
that
you
want
to
use.
A
In
a
way,
but
but
once
again
at
that
point
we
have
specialized
components
like
if
we
were,
for
example,
using
that
rotary
switch.
I
like
using
the
diagrams,
because
I
can
show
the
actual
picture
of
the
actual
component,
which
fritzing
may
not
have
that
component,
like
fritzing,
will
be
more
generic.
A
A
A
Pretty
much
you
might
have
to
do
some
variations,
just
some
little
changes,
but
yes,
that's
the
beauty
of
it.
You
have
to
mess
around.
Oh,
how
you
can
actually
lay
this
out.
You
give
it
the
actual
symbols:
here's
the
resistor,
here's
the
