C
A
A
So
I
did
a
good
deal
about
the
the
new
stepper
driver.
Little
tips
there
out
there
and
the
reasons
are
a
couple.
So
it's
on
the
page
called
tiene
seat,
one
third
on
the
Wiggy,
so
you
see
we
still
got
around
a
standard
controller
with
this
little
pluggable
stepper
drivers,
but
in
use
here
isn't
and
I
was
trash.
Shake
this
out
is
a
recent
and
the
relatively
recent
kind
of
a
thing
which
is
back
a
2016
already,
the
type
of
a
little
stepper
driver
that
that
is,
one
complete
silent.
A
So
if
you've
ever
a
3d,
printer
and
they're
noisy
or
quite
a
quite
noisy
and
the
step
motors
go
and
run.
But
this
one
is
completely
silent
and
the
other
thing
is
about
it
is
that
you
can
end
up
doing
sensorless
homing
using
the
TMC
21:30
stepper
driver.
So
you
can
take
a
look
at
all
that
now
in
order
to
use
the
subsolar.
Can
we
do
that?
How
simple
is
actually
been
implemented,
without
bench
being
rid
of
you
to
end
stops
and
not
only
to
ends
up
sitting?
I
was
just
reading
about
this.
A
You
can
probably
do
this
yen
stopped
as
well,
which
is
now
the
goal
so
instead
of
using
provenance
as
basically
the
when
motor
moves,
it
detects
a
bomb
like
it.
If
you
bump
into
something
that
mean
the
current
is
gonna
go
slightly
out
in
a
stepper
driver
and
that
detected
and
Marvin
is
actually
set
up
that
all
right,
the
the
Flyers
are
can
handle
that.
A
D
A
A
So
just
a
few
little
inconveniences,
including
a
bunch
of
rework
of
code
in
terms
of
a
bunch
of
things
and
to
have
to
be
worked
through
out
in
the
code,
so
not
absolutely
transparent,
but
quite
doable.
Now,
there's
bad
news!
There's
best
EMC
2130
now
just
recently,
but
I've
got
a
lot
here,
so
it
c'mon,
which
is
the
TMC
to
208,
which,
after
somewhat
being
disappointed
by
the
team,
seem
to
130
in
terms
of
throw
rework
of
the
software.
A
A
All
of
you,
the
censors
homie,
it
will
get
you
the
complete
silent
operation,
that's
good
as
far
as,
if
you
want
to
know
right
now,
I
could
be
in
this
meeting
and
running
might
in
turn,
act
imme
and
it
couldn't
just
run
in
the
background.
Without
looking
any
noise.
That's
that's
really
good.
If
you
have
say
your
home
office
filled
with
three
printers
and
otherwise
yeah
I
mean
kind
of
would
have
to
have
your
knobs
your
plots
or
having
a
few
de
you're,
not
sensitive,
that's
fun,
but
I
mean
just
make
Holden
noise.
Oh!
A
So
once
an
operating
is
awesome.
It's
alright!
Now
that
that
turned
out
without
any
any
changes,
the
TMC.
Oh,
it's
you
don't
have
to
rewire
them
anyway
or
hinge
the
firmware
they
run,
as
is
to
get
you
the
super
silent
mode,
another
advantage
of
pay
because
it
it
it
actually
gets
to
higher
set
microstepping
like
right.
Now
we're
on
it's
sitting,
micros,
to
being
it's
still
bombing
this.
A
The
DMC's
have
256
snappy
names,
the
maltiness
super,
so
it's
an
abscess
myth,
so
they're
reports
that
a
print
quality
actually
goes
up
because
you
get
last
lesson
of
these
are
inertial
effects
of
this
nepo
modem
going
through
its
steps,
neither
its
cost.
You
know
look
like
very
smooth.
You
look
at
this
really
like
very
tiny
bumps
in
emulsion
with
a
separate,
more
moves.
So
that's
really
good
stuff,
while
doing
now
here,
then
not
all
go
to
the
duplicate
here
out
to
the
3d
pair
critical
path.
A
So
what
does
that
mean
for
what
I'd
like
to
do?
I'll
go
to
grifoll
path,
I'm
kinda,
leaning
out
where
the
perhaps
of
priorities
in
terms
of
okay,
the
next
doesn't
development.
So
let
me
do
the
release
of
the
next
and
improved
version
printer.
So
first
of
all,
I've
got
the
as
I
mentioned
last
week,
doing
3d
print
corners,
so
you
don't
have
to
weld
the
frame
right
now.
I'm
also
testing
this.
A
It's
actually
a
clone
of
the
Titan
arrow,
but
it's
got
hardened
geared
and
extruder,
which
is
good
so
that
extruder
gear
in
the
her
like
really
never
wears
out
like
he
used
the
race
of
filaments.
It
would
wear
out
after
sometime
not
a
big
deal,
but
something
look
at
another
thing
is
that
we're
still
not
set
up
like
like
the
printer.
A
It
gets
completed
eight
by
eight
inch
and
I
just
have
to
be
said
that
little
bit
in
on
the
code
in
the
12-inch
prime
Trevor,
we're
able
to
get
well
for
the
12
inch
frame,
which
is
convenient
and
that
it's
shippable
when
you
press
flux,
which
is
12
inches,
hey,
didn't
that
we
can
get
a
by
a
using
the
current
geometry
that
the
print
out
of
the
12
inch
frame
so
just
bring
that
into
I'm
gonna
clean
up
to
our
passes.
I.
A
A
So
one
point
or
millimeter,
two
point:
eight
millimeter
actually
quadrupling
the
seat
of
printing,
so
that's
attractive
until
now
to
lock,
yes,
yeah
the
side
detail
on
the
cable
chain
and
that
the
first
isse
and
the
current
version,
which
is
19,
that
is
just
a
little
eyes
man,
just
just
one
pic
so
my
people
chain
piece,
that's
movie!
No
I
also
have
3d
printer
control
panel
right
now
we're
putting
out
control
palette
of
blessing
glass.
A
Well,
no
reason
why
we
can't
print
it
out
pretty
soon
we
get
rid
of
one
additional
part:
the
Cabal
pal,
where
you
move
all
electronics
that
might
as
well
be
3d
printer
perfect.
So
you
can
print
out
all
the
holes,
so
we
gotta
do
all
the
drilling
for
mounting
other
components.
So
that's
a
real
time-saver
for
the
production
here,
standpoint,
3d,
printer
control
panel
out
of
PLA,
rads
or
whatever
right
now
we're
using
able
the
little
zipped
us
to
etch
all
the
component
stuff
like
the
power
supply
everything
else
and
then
gotta
update
the
atom.
A
The
overall
printer
know:
where
is
the
team's
to
away
that's
actually
right
here?
So
that's
immediate
priority.
Do
you
see
a
drop
at
a
placement,
Milko
changes
and
if
you
want
to
make
for
the
TCC
to
the
labeler,
we
need
to
just
reverse
one
wire.
The
wire
wire
connecting
to
Stefan
where
there
might
get,
pin
reversal,
need,
stop
and
that's
physically
to
do
a
very
minor
detail.
A
Otherwise
you
and
everything,
as
is
using
run
our
still
Accords
and
Marlin,
like
we're
on,
like
one
point,
zero
latest
that
all
the
sensorless
homing
stuff
is
that's
in
Marlin,
1.9
and
higher.
That's
why
it's
1982!
It
doesn't
require
the
higher
higher
Marlin.
He
was
existing
Marlin,
but
eventually,
when
I
switch
over
just
just
do
old,
firm
or
not
it
and
that's
Japan
big
deal
just
updating
code.
So
we
can
take
the
foot
power.
Take
advantage
of
the
power
the
sensor
is:
holding
the
quiet
operation
now
complete
control
of
the
the
stepper
current
through
sulfur.
A
It's
no
longer
the
eternal
knob
on
a
super
Drive.
We
actually
get
up
through
the
code
through
the
firmware.
So
that's
basically,
the
new
stepper
drives
are
very
configurable
for
complete
quiet
operation
and
since
there
was
detecting
when
they
hit
something
and
also
the
thing
like
when
you
lose
power,
take
actually
they
had
a
capacity
to
return
to
proper
trending
because
it
can't
remember
where
they
lost
power.
A
So
that's
a
feature,
that's
not
in
Martin
yet,
but
whose
printers
do
have
that
in
their
system,
Bruce
isn't
leading
the
way
in
their
custom
model
in
their
own
firm
with
development,
which
is
based
on
more
than
but
doesn't
degrade
it
to
merlin.
Yet,
as
far
as
like,
when
you
lose
power
and
able
to
please
restart
a
rant,
because
my
software
setup
for
Palos
instances
so.
A
12A
didn't
ride
twelve
frame
and
it
was
talking
last
week.
Inner
to
use
100%
of
the
material
flow
crowd,
a
metal
sheet
of
one,
a
thirsty
lips.
Currently
what
we
use
for
the
printer,
the
the
last
smaller
size,
a
tenant
tange
frame,
which
can
handle
a
second
bed
and
we
actually
the
micro
version
at
four
or
five
inch
bed
using
the
thermal
cutout,
which
is
eight.
A
We
can
still
do
about
a
four
or
five
inch,
but
micro
aprender.
Well,
there
is
that's
not
a
crazy
thing.
There's
clean
up
printers
are
tying
like
the
micro
size.
Printers
would
have
four
or
five
it
beds,
so
that
still
makes
sense
enough.
You
can
do
plenty
of
pasta.
Our
four
inch
I
mean
four
inches
still
sizable
flip.
If
you
say
one
of
her
in
fittings
of
various
other
components,
so.
A
So
I'm
the
twelve
into
production
engineering,
just
continuing
on
that
and
focusing
on
getting
that,
including
the
quiet
by
verso.
One
major
implements
gonna,
be
that
the
max
iteration
with
the
TC
to
to
the
low
a
it's
going
to
be
completely
silent.
And
after
that
we
can
worry
about
the
sensorless
homing
operation.
A
It's
gonna
be
a
little
bit
more
of
che
down
over
that
whole
system,
because
you
have
to
fine-tune
all
the
current
settings
and
everything
else
that
when
you
bump,
how
do
you
know
that
you
bobble
exactly
what
threshold
do
you
set
within
the
software?
Her
understand
that
that's
a
bomb
not
just
a
regular
motion
with
the
printer,
so
it
was
a
very
fine
tuning,
a
lot
of
finding
they're
just
probably
take
them
there
to
work,
but
and
then
he
gets
ounces.
You
get
ready
for
say
the
summer
school
in
July.
A
A
Ya
know
just
you
know
one
more
comment
on
ya:
the
bootcamp
429
aimed
a
summer
school.
So,
as
I
said
last
time,
focus
will
be
so
so
really
just
mastering
the
reprinting
for
structure,
including
ability
to
make
filament
and
doing
a
large
print
or
so
right.
Now,
if
we
go
to
camp
2019,
current
proposed
schedule
is
so
that's
P
19
schedule.
So
we
do
the
3d
per
bill
as
normal.
They
could
focus
on
making
as
I
thousand
three
cats
and
can
everyone
this
was
out
in
Compton.
A
They
can
actually
produce
basic
designs
in
three
had
then
we
do
the
filament
maker
infrastructure
on
day
three
on
and
if
we
have
the
film
that
maker
can
start
again
plastic
than
we're
ready
to
print
very
large
things
so
before
looking
at
building
the
large
3d
printers.
So
basically
one
meter
had
where
the
z-axis
letters
for
z-axis
and
XY
entry
is
moving
on
top
those
four
Z
at
ease
and
why
that
comes
strategy?
That's
different!
A
What
we
had
now
right
now
the
XY
Gary
has
fixed
the
top
and
the
bad
moves
up
and
down
well
with
a
one
meter
bed,
just
the
weight
of
that
is
life
like
it's
an
eighth
inch,
steel,
that's
reinforced,
but
ends
up
weighing
quite
a
bit.
It's
I
think
it's
like
50
pounds
or
so
50
or
60
pounds
without
a
friend.
Now,
if
you
talk
about
doing
big
prints
on
that,
we're
gonna,
add
why
Sir
three
or
four
to
a
full
print
I'm
on
them,
you're
bad.
A
If
you
filled
out
the
whole
bad
like
if
you
didn't
like
one
solid
cue,
that's
I
think
it's
400
kilos,
it's
God's
up,
but
yeah
like
a
couple
of
people's
right.
If
you
do
a
full
3d
printer,
really
it's
heavy,
so
you
will
mix
the
bed
at
the
bottom
and
move
the
gantry
up
and
down.
Then
this
we
do
large
any
printer.
So
that
would
that
me
be
the
thing
to
do
the
wide
we
have
to
go
to
makes
like
either
like
super
high
gear
down
or
much
better
stuff
motors.
The
things
like
that.
A
So
keep
it
more
simple
with
more
metal
part.
Next,
bad
and
bottom,
so
you
not
to
lift
that
I
struggle
just
a
little
gantry,
okay,
so
to
wrap
up
the
schedule
on
them
on
summer.
So
here
so
day,
five
I
feel
be
a
nice
idea.
This
is
kind
of
like
she's
gonna
schedule
down
here,
but
I
think
using
the
poly
cat
wouldn't
be
pretty
woman.
Where
you
can
do
lost,
lost
plastic,
3d,
printing.
A
She
then
filled
with
metal,
so
lost
yeah
lost
its
I.
Think
it's
a
form
of
PLA.
It's
a
loss,
plastic
metal,
casting
I
think
that's.
That
would
be
really
begin
right
into
not
only
plastic
pots,
but
enough
parts
there.
It
has
processes
of
three
prints
and
that's
that's
a
very
much
accessible
technology
using
a
3d
being
a
film
and
that
dedicated
for
that
Network,
which
burned
out
completely.
So
you
know
you
have
to
like
burn
it
out.
A
A
Nine
thousand
psi
or
thirty
thousand
psi
of
nets
and
that
as
strong
as
mile
steel,
so
here
we
get
access
to
very
strong
parts
from
320
and
then
a
six
and
seven
was
it's
gonna
focus
on
just
just
using
all
the
techniques
we
learned,
and
so
3d
printing
and
the
potential
look
with
model
to
like
to
do
a
little
bit
of
work
on
the
cordless
drill
or
other
projects.
I
would
like
to
build
I
mean
if
you
have
number
winters
wrong
at
that
time.
A
We
have
the
option
to
build
all
of
a
CNC
machines
that
CNC
router
even
a
heavy-duty
CNC
machine.
If
people
are
willing
to
do
that,
I
can
I
will
open
that
to
to
the
crowd
/
I
like
to
see
them
worked
on
a
cordless
drill,
which
is
a
very
sighting
project.
That's
really
lent
itself
well,
Tiffany
printing,
including
the
bundling
nanoporous
and
then
something
larger,
see
the
machines
based
neither
verse
axes
and
we're
gonna
have
that
as
an
open
feel
a
couple
of
days
where
we
recommend
actually
getting
to
a
real.
A
It's
been
we're
all
its
decided.
I'd
I
just
spread
all
to
just
don't
bond
around
a
product
will
decide
to
well.
Okay,
let's
let's
do
this
thing
on
this
couple
days,
using
all
the
prototyping
velocity
like
10
or
20
3d
printers
so
know
pretty
good
I!
Think
that's
for
me
for
what
I've
got
so
far.
So,
let's
move
on
to
the
others
who
wants
to
annex.
B
A
D
Yeah
not
directly
this
making
a
plastic
site
making
a
mold
out
of
a
material,
calcium,
aluminate,
cement
and
plaster
Paris
mm-hmm.
You
dissolve
the
plaster
Paris
away,
and
then
you
have
roommates
MIT.
So
it's
gonna
be
a
hard,
precise
mold.
Yes,
we
can
we're
actually
milling
mold
in
there's
like
carrot
to
explain,
but
I
actually
have
a
video.
D
D
This
has
been.
This
is
a
process
that's
been
adopted
since
1892.
Actually,
there's
different
courses
called
the
shape
transition
modeling,
so
to
call
it
accident,
just
a
sculpture,
but
basically
you're,
doing
you're
putting
the
tire
layer
down
once
as
a
sort
of
thin
rectangular
block.
They
may
subject
to
a
milling
operation
when
you
do
that
repeatedly
to
build
up
layers
of
calcium
aluminates
in
a
test
case:
richer
milled.
C
D
D
D
A
C
D
To
serve
right
up
on
the
blonde
and
brightest
and
then
reason
it's
not
use.
It
said
it's
much
better
than
intent
because,
with
the
grits
every
cyclist
hand
yeah,
but
the
kissing
a
little
measurement.
It's
like
it's
like
just
like
a
little
scent.
It's
real,
cheap
stuff,
it's
like
10,
bellows
or
the
50
pound
bag,
or
something
so
if.
D
D
D
See
mr.
an
enormous
variety
of
different
refractory
materials,
but
most
still
actually
made
slightly
it's
still
guessing
temperatures
and
that's
gonna
hurt
like
just
run
in
the
middle
okay
since
but
Lynette,
that's
not
going
to
send
the
temperature
steel
catenary
exactly
yes,
what
suddenly,
but
make
you
a
little
bit
of
hiking
and
stuff.
This
is
good
for
the
rivers.
D
D
A
D
A
D
Calcium
aluminate
mint
is
both
calcium
oxide
and
aluminum
in
a
crystalline
structure
where
they
are
like
molecules
are
trained.
Like
so
I,
don't
know,
I
like
you,
they
have
all
these
non
men
is
that
firms
mechanics
not
polite
when
it
on
the
server
fracture
materials.
A
lot
of
the
marks
are
kind
of
interchangeable,
but
I
would
just
get
the
pure
costume
eliminate
sent
on
Aliexpress
or.
D
D
B
B
D
A
D
A
D
D
D
There
is
yeah,
there's
a
page
since
our
cottage
I,
don't
know
if
you
heard
it's
America,
yeah
Joe,
yeah,
I'm,
deaf
you,
but
it's
instance:
our
projects
site,
it's
kind
of
very
another
website
illness.
It's
not
very
good
website,
but
they
have
a
section
for
projects
and
on
there
we
have
some
documentation.
A
D
D
D
D
A
D
Parts
made
from
art
nope
we've
made
through
milit
we're
gonna,
get
that
maybe
even
a
little
bit
better
cuz.
There's
no
shrinking
and
stuff
need
to
the
polar
thing.
Yeah
taeyeon
homes
about
it,
because
it's
just
like
when
you
need
something
to
seal
against
fluid
or
Gears
that
dough,
making
less
and
last
a
long
time
or
you
need
all
fans
and
stuff
like
that.
Like
you,
gotta
have
accuracy
and
you
have
it
smooth
surfaces
right.
It's
3d
printing
is
great
for
pasta,
but
if
you
can't
barely
get
the
last
couple,
my
condo.
D
D
Now,
when
it
comes
to
aluminum
or
steel,
like
you
say,
the
conventional
dough,
just
dude
just
cast
approximately
what
you
want
and
then
machine
to
final
dimensions
and
I'm,
not
sure
how
well
we're
gonna
be
able
to
do
there,
but
certainly
true
with
if
you
search
like
premium
injection
molding,
all
right,
Remy
investment
casting
you
can
find
some
companies
that
are
advertising
it's
their
accurate
up.
They
don't
need
post
machine
it
all.
It
next
shade
casting
sometimes
there's
a
couple
different
terms.
It's
not
very
common,
but
it's
the
thing.
D
D
D
A
A
C
A
D
B
D
B
A
A
A
Key,
no
okay,
so
Jade
you
printed.
That
course
so
take
like
this.
This
would
I
big
hard
cop
is
doing
alright
communica
with
a
money
money
restored
immediately.
But
you
did
this
to
split
ring
it's
one
of
these
things.
I've
never
heard
of
and
I
couldn't
leave
it
like,
but
this
little
stepper
motor
act
worse
and
inside
the
casing.
A
It's
it's
close
but
bring
planetary
gear,
and
he
had
this
little
motor
harden
the
fact
so
viy
here.
But
this
thing
here
had
like
500
steps
per
revolution.
It's
like
whoa!
How
do
you
do
that?
Well,
the
secret
is
this:
it's
called
a
slit
ring
here.
You
have
to
you
can
run
away
under
three
printed
stepper
motor,
but
the
idea.
A
Gear
we're
in
two
halves:
one
half
is
essentially
like
1/2
or
a
couple
of
beef
different
than
the
other
half
and
what
happens
when,
when
you
move
the
one
part
around
long
time.
The
other
part
moves
around
only
like
one
or
two
teeth,
in
other
words,
give
this
huge,
huge
gear
down
from
this
kind
of
system,
so
I'm
actually
very.
A
I
was
looking
at.
We
should
try
to
build
this
during
the
the
summer
camp
or
you
know
perhaps
Christmas
absolute
spectacular,
since
it's
got
the
same
form
factor
as
a
NEMA
17.
It's
got
the
simple
electromagnet
mechanism
in
the
back,
and
it
gives
us
amazing
geared-
and
so
this
to
me
is-
is
getting
board's
high
practicality
and
but
can't
make.
D
A
D
A
Surfaces
do
not
have
like
a
hundred
times
more
torque
in
here
nepeta,
plus
the
motive
of
the
advantages.
This
is
much
more
geared
down,
in
other
words,
for
the
same
amount
of
work.
Think
about
they'll,
make
separate
mowers
to
have
look
three
five,
maybe
ten
planetary
gear
down
the
serve
their
types
of
your
own
agenda,
you're
talking
like
100
or
200,
but
with
this
names
that
are
more
like
this.
His
vision
for
precious
plastic,
lime,
rind
or
nobody
go
for
so
very,
very
small,
but
the
port
would
be
here
and
yeah.
A
The
platic
wouldn't
hold
that
the
kind
of
pork,
but
if
you
enlarge
the
pieces,
yes
and
absolutely
can't
so
this
offers
miss
the
main
wall
point
is
it's
all
3d
print,
it's
the
hundred
years
and
pretty
simple
like
a
Magnum.
So
the
combination
from
name
is
Dave
art
cop
and
said
that
just
like
magnets
for
heat,
so
you
gotta
insulate
them.
So
they
don't
melt
your
plastic
but
yeah.
So
there's
nothing!
Development!
Look
about
I
just
found
us
just
the
very
conduct
of
this
living
planet
on
here.
A
If
you,
google,
that
shred
it
I've
just
not
a
super.
Fascinating
there
from
the
cysts
hi
tiny
one
factor,
you're
actually
getting
100
or
more
type
of
mutant.
This
is
because
I
mentioned
something
before
about
sacking
platyrrhini
as
well.
You
can
send
lean
to
that
with
many
more
parts,
but
here
you
don't
have
to
so
just
a
heads
up
on
reducible
mechanism
here
so
anyway.
I'll
leave
it
at
that
I'll.
Do
the
3d
printer.
A
A
Them
it's
just
like
Electra,
it
doesn't
get
today,
I
mean
conceptually
yes,
but
they
have
these
fine
teeth
and
magnet
parts
of
the
metal
parts
in
there
that
allow
for
that
very
nice
being
preserver
fine
structure
in
this
over
you
and
I've
got
level
you're
talking
about
okay,
you
need
to
machine
that
precise.
You.
A
It's
this
miss
route
here,
I
shot
with
us,
but
we're
in
planetarium
here,
there's
just
a
pole
sheet,
because
you
don't
have
to
go
to
that,
but
the
same
kind
of
complex.
It's
a
completely
different
mechanism.
Instead
of
using
fine
resolution
you're
using
the
gear
down
for
the
resolution
and
a
stool
factor,
the.
B
D
B
B
C
So
I
had
the
nozzle
humbly
spoke
library
and
at
the
zoo
library,
they're
kind
of
a
comparison.
This
was
a
kind
of
experiment
for
it
on
the
conversations
I
had
with
people
explode
seems
like
a
lot
of
you
are
interested
in
printers,
but
they
don't
necessarily
need
to
get
their
own
up
and
running.
So
a
public
library
is
very
cheap
than
yours,
see,
library,
give
you
a
little
kind
of
a
better
friend,
but
it
was
five
times
more
expensive,
ten
dollars
for
just
two
dollars.
C
A
C
A
A
And
there's
only
some
problem
here:
focus
on
getting
back
into
large
grants
into
Charlie
coming
making.
This
would
be
as
just
not
sure
of
all
production
that
can
be
doing
just
in
the
machines
or
shapes
to
be
able
to
do
the
level
of
word
or
making
a
plaster,
and
therefore
that
process
is
inexpensive,
not
to
mention
that
we're
getting
into
the
close
of
material
cycles
using
3d,
printing
and
hopefully
getting
into
some
more
of
the
metal.
The
work
that
results
will
be
printing
and
the
casting
our
systems.
D
D
A
A
A
Something
like
that,
yeah
look,
consider
that
I
decided
to
talk
to
William,
because
we're
gonna
do
that
together,
slowly
I'm,
throwing
on
the
International
Academy.
Oh
he's
gonna
do
some
other
work
on
us
with
Arduino
LMS
and
also
be
done
with
the
motor
set
he's
prototype
using
3d
printing.
So
we
understand
the
concerns.
D
A
That
requires
a
bunch
of
structure
and
things
like
that
to
happen,
and
some
staff
to
support
that
so
won't
have
it
folded.
Well,
I
think
the
wireless
thing
I
didn't
put
some
pages
in
a
wiki
about
surf
school
that
in
2020
we
can
be
also
something
that's
like
full
blown-out
development,
lots
of
people
and
so
forth,
because
behind
that
with
the
cordless
drill,
Chandra
their
incentive
challenge
that
that
working
on
in
terms
of
vetting
is
build
out
for
that
and
they're
prototyping
on
all
kinds
of
different
things.
But
yeah.
It
takes
some
resources
and.
D
D
Going
on
when
you
want
to
do
that,
you're
gonna
in
the
back
room
help
me
get
out
of
it,
but
I
think
also
I
know.
Other
people
would
definitely
join
yeah.
But
it's
like
when
doing
your
opportunity
when
you
OP
and
he
comes
in
your
life
and
sometimes
it
close
again,
you
know,
and
then
you
have
a
job
or
whatever
ro
I
hope
we
can
do
it
soon.
Yeah.
C
A
A
Stan
filming
so
you
can
do
that,
but
I
mean
that
you're
gonna
suffer
on
I
can
cuz.
You
know
you
have
to
put
a
lot
of
good
effort
into
making
that
extruder
reliable.
Since
first
you
just
know
at
the
end,
and
you
don't
have
control
as
I'm
well
defined
three
millimeter
or
1.75
millimeter
film.
She
knows
they're.
You
know
hard
yet
to
push
it
to
be
much
more
much
more
finicky.
All
that
now
there
are
do
that.
A
Like
our
example
thing
about
attraction,
if
you
have
an
extra
on
top
of
a
with
a
bunch
of
multiplies
like
your
extraction,
your
retraction
very
limited,
now,
there's
only
so
well,
you
can
control
that,
so
we
had
some
much
harder
proposition,
but
that
lead
a
global
just
gets
a
completely
new
friend
kind
of
technology
scheme.
Yeah,
okay,
just
kissed
yeah,
but
I
mean
it's
all.
Syllables
much
I
already
have
to
do
an
introduction,
but
as
far
as
like
the
reason,
why
not
some
much
more
thought
I
mean
people
have
tried.
A
Yeah
yeah,
that
sounds,
it
sounds
good,
so
yeah
I
think
yeah.
Let's
wrap
up
on
this.
Let's
see
thanks
Jen
for
posting.
You
know
virgin.
Does
our
videos
on
deaf
team
page,
it
said
and
like
my
post
and
I'm
gonna
finish
partying,
is
it
inside
cuts
I'm
basically
done
with
putting
in
all
info
on
the
video,
and
that
thing
is
already
halfway
uploads
somehow
and
get
us
upload
right
after
the
business
we
have
posted
to
the
line
now
so
take
a
couple
of
minutes
to
open
it.
So
it's
that
right
after
I
mean
wait.
