A
That's
miles
miles,
hi
good
good,
to
see
you
so,
okay,
I'll
do
a
little
bit
of
update
on
professional
development.
Kit
builds,
let's
see,
Abe
got
continuing
work
on
d,
3d
mini
and
then
miles
on
DC
to
DC
converter
now,
which
which
I'm
gonna
ask.
What
does
it
take
to
turn
that
into
a
power
supply
for
the
3d
printer,
which
goes
from
120
AC
to
to
12
volts
DC,
but
that's
later
so,
I'll
start
by
updating
on
latest
progress
in
town
here.
A
So
regarding
the
3d
print
cluster,
so
you
see
on
the
slide
number
4,
that's
kind
of
how
it's
looking
right
now,
but
go
to
slide
3
and
you
see
a
little
homebrew
of
the
next
version
of
the
extruder
with
an
underslung
carriage.
So
what
you
see
there
is
what
I?
Actually
it's
currently
printing
right
now,
I'm,
actually
printing
that
out
right
now,
but
the
idea
there
is
instead
of
mounting
the
extruder
horizontally
like
well
we're
in
a
carriage,
take
a
look
at
slide.
Number
four:
you
see
the
where
the
extruder
is
it's.
A
Basically,
the
x-axis
has
the
carriage
going
vertically
up
and
down
now
in
this
design.
Here
you
see
the
carriage
is
kind
of
like
left
and
right.
It's
hanging.
The
texture
is
hanging
down
from
it,
there's
a
reason
for
this
change,
so
the
reason
is
that
we
actually
have
issues
on
the
mounting
with
when
we're,
using
through
your
ball
straight
through
the
extruder
to
the
the
plastic
pieces,
the
Polsky
tend
to
get
loose,
we're
not
mounting
by
the
faceplate
like,
which
is
then
the
street
standard.
A
Yes,
so
you
see
the
little
triangle
here
and
the
back,
so
this
extruder
here
is
mounted
to
the
base
plate
of
the
motor.
So
the
motors
behind
hidden,
there's
a
fan,
cooling
fan
and
that
that's
the
sensor
holder
here,
but
that's
the
carriage
piece
where
the
rods
rods
are,
but
the
extruder
mount
is
integrated
to
the
carriage
piece.
So
they
can.
So
if
you
go
to
d3
partland
part
library
not
really
be
3d,
part
library,
it's
actually
hidden
at
3d
printer
extruder.
A
I'll
go
to
the
first
part,
and
that
is
the
extruder
mount
suits.
So
it's
a
modified
carriage
peace
with
the
hole,
the
mount
system
for
the
stepper
motor
and
for
the
extruder
and
it's
a
very
basic
kind
of
a
design.
But
it's
hard
to
print
cuz.
It's
got
a
lot
of
overhang
so
but
that's
what
I'm
printing
right
now,
if
you
go
to
I'll,
just
paste
that
link.
A
So
you
can
download
the
file,
so
the
addition
here,
notably
has
integrated
carriage
with
the
extruder
mount
edition
of
a
print
cooling
fan.
Now
we
haven't
been
using
a
print
cooling
fan
until
now,
so
that's
I
mean
that's
a
you
actually
need
a
print
cooling
fan
for
higher
quality,
no
question
about
it.
You
can
still
print
without
it,
but
you
get
better
overhangs
and
better
coolers.
The
idea
is
that
when
you
lay
down
plastic,
you
will
in
order
for
it
to
do
overhangs.
You
have
to
freeze
that
plastic
like
ice
in
the
mid
air.
A
Otherwise
would
do
upon
you
so
anytime,
it
goes
over.
Any
overhang
is,
will
attempt
to
droop,
but
if
you
have
a
fan,
print
cooling
fan
and
the
nozzle
has
not
shown
they're
actually
for
the
fan
nozzle
not
shown
yet,
but
in
it
would
go
down
and
point
to
the
to
the
nozzle
of
the
extruder.
So
that's
that's
what
I'm
working
on
here?
Also,
if
you
look
at
build
one
and
build
two
time-lapses
out
of
the
complete
D,
3d
3d
printer,
build,
and
so
I
have
done
one
that's
in
five
hours
and
60
minutes
last
week.
A
So
that's
where
we
left
off
last
week:
I
did
another
one
shipped
from
so
that
was
shipped
by
Sarah
from
California
and
Alex
from
California.
I
was
basically
testing
the
kit,
whether
it's
buildable
and
getting
further
data
on
the
build
time
for
the
3d
printer
to
get
really
comfortable
with
six-hour
bills,
as
that
doesn't
know
arm,
and
that's
what
we're
teaching
our
people
to
do
right
now,
because
that's
the
kind
of
efficiency.
A
If
you
really
understand
the
printer,
it's
not
an
issue
to
build
in
about
six
hours,
but
you
really
have
to
understand
and
understand
all
goes
together.
That's
my
report
on
the
3d
printer
I
also
want
to
talk
a
little
bit
about
Aussie
clubs,
because
I'm
actually
picking
off
to
London
Ontario,
actually
in
two
days
to
the
first-ever
three-day
immersion
training,
out
of
which
were
we're
starting
an
LSE
Club
and
the
London
International
Academy
in
London
Ontario
Canada.
That
is
so
that's
good
news
and
trying
to
build
a
team
that
way
as
well.
A
B
C
B
B
So
we
get
the
simplest
either
way
if
you
could
add
a
whole
thing
on
there
somehow
on
the
end,
but
it
would
probably
be
pretty
clumsy
cuz
you'd
have
to
have
a
way
to
open
it
up,
pry
it
open
and
get
over
the
pipe
and
that
kind
of
stuff
and
then
bolt
it
on,
but
something
that
just
snaps
on
is
kind
of
the
the
simplest
thing.
Yeah
and
I
don't
know.
A
B
C
A
Yeah,
that's
interesting.
I
have
a
comment
on
that,
and
that
is
you
know.
You
can
also
use
like
this
clamp
collars
and
we
can
3d
print
those
as
well.
Well
maybe
you
have
this
clamp
which,
which
is
dedicated
for
yeah.
Double
split,
clamp
collar
sink,
and
you
can
put
it
on
so
say
you
put
this
on
and
then
wants
to
slip
down,
especially
if
you
maybe
like
in
the
different
temperatures
or
whatever
would
be
some
extra
heavy,
printing
or
fast
printing,
but
you
also
use
a
clamp
collar
which
would
be
a
double
split
clam
collar.
B
A
B
B
C
B
B
C
B
A
A
A
B
Of
hit
that
first
and
then,
though,
I
was
hoping
mainly
that
it
would
be
a
3d
printable
part
as
it
is
in
the
photo
like
it'll
sit
on
the
bed.
Like
you're
saying
you
probably
need
cooling
and
all
that,
but
something
that
the
shape
of
it
could
be
adapted
to
where
it
would
not
require
any
support.
And
things
like
that.
A
lot.
A
B
C
B
E
A
I
mean
one
way
to
go
about.
This
is,
if
you
put
a
little
little
hole
in
the
side,
just
put
a
little
set
screw,
you
know:
can
you
use
set
screws
into
yeah
weakened
up?
There's
a
set
screw
on
this
device
to
hold
to
prevent
it
from
slipping
as
well.
I
mean
set,
screws
are
quite
accessible
parts,
so
yeah
yeah.
A
A
A
B
B
A
B
Might
go
up
to
and
we
might
have
even
contact
thinking
about
that
PVC
frame
isn't
want
everything
and
I.
Think
I've
put
some
notes
back
in
the
working
duct
for
the
D
3
D
PVC
many
good
stuff
there,
but
a
lot
of
the
issue
is
the
accuracy
of
the
frame.
Obviously,
regardless
of
whether
it's
plastic
and
how
much
we
can
stabilize
that
putting
it
together,
everything
has
to
be
cut
pretty
accurate
and
then
assembled
accurate,
there's
a
bunch
of
stuff
related
without
to
try
to
get
the
the
squareness
fact.
E
A
B
So,
partly
when
you,
if
you're
gluing
the
PVC
together,
eventually
it
that's
about
mostly
marking
and
laying
stuff
out
and
having
a
good
process
for
that,
but
I'm
gonna
figure
out
what
I
can
I've
measured
about
your
stuff,
including
the
the
distance,
took
like
the
limits
which,
where
it
was
on
some
of
the
other
stuff,
because
I
realized.
That
was
the
actual
length,
the
the
movement
length
of
the
unknown
axis
this
under
this
one,
there's
got
to
be
one
limit,
switch
on
every
axis,
at
least
right,
so
yeah.
B
A
B
So
it's
kind
of
figuring
out
the
rook,
the
rod,
length
and
and
the
other
distances
around
the
axes
parts
will
determine
kind
of
a
formula
for
figuring
out
what
the
other
sizes
of
parts,
so
the
frame
can
be
scaled
and
so
on
cuz
be
what
you
3d
print
a
certain
size
of
clamp.
Obviously
you
don't
have
to
make
an
adjustment
on
that
for
other
frame
sizes
or
something
like
that.
It's
gonna
have
to
be
some
multiple
of
the
size.
A
A
B
Yeah
I
see
one
of
chair
figure
out
how
that
look
at
potential
printing
on
the
on
the
parts
I
thought
I
had
to
I
guess
my
Krishna
Lennox
is
old.
Oc
Linux,
install
and
I
had
a
version
of
cure
and
I
guess
the
new.
What
is
mosebach
cure
as
the
most
recent
instructions
I
found
on
the
wiki
were
so
sure.
If
I
don't
know,
the
ose
Lennox
has
has
all
the
most
recent
updates.
For
that
is
there?
A
B
B
How
that
works,
I
I,
don't
have
a
printer.
It's
see
how
to
set
that
up
too.
It
shows
pretty
accurate
I
think
how
the
pranking
is,
but
I'm
not
I'm,
not
just
not
very
familiar
with
the
interface,
but
it
seems
to
show
what
you
know.
Objects
might
need
a
support,
or
you
know,
having
make
print
or
not
just
the
part,
pipe
pieces
to
the
parts
for
the
frame,
because
they
were
apparently
the
wrong
sizes.
Somehow
I
don't
know
they
got
generated
differently.
C
B
I
tried
to
adjust
the
I
wanted
to
adjust
the
STL
and
so
on,
first
on
the
corner,
so
that
it
would
sit
as
you
suggested,
op
Nam
as
he
accessed
to
look
at
how
that
would
print
I
I.
Guess
it
probably
print
that
okay,
it
seemed
to
cure
there.
It
seemed
to
highlight
some
areas
that
it
thought
were
problematic,
but
I
assume
that
depends,
as
he
said,
on
how
how
cooled,
how
slowly.
A
C
A
A
D
A
A
Yeah
so
and
then
it
becomes
interesting,
like
you
know,
for
people
who
work,
you
know
people
who
do
housing,
there's
vinyl
filament
to
PVC
filament
for
3d
printing.
You
can
recycle
it
now.
The
fumes
aren't
great.
You
have
to
have
invented
and
have
measures
for
understanding
the
safety
around
that,
but
so
it's
not
for
everybody,
but
it's
a
doable
thing
it's
better
than
making
new
PVC
in
terms
of
pollution,
so
recycling
is
always
better
but
still
have
to
be
careful
about
safety.
A
D
A
A
A
D
A
D
A
Yeah
or
if
we
have
a
24
volt
batteries
turn
that
into
like,
for
example,
in
the
city,
go
home,
we've
got
24
volt
battery
system
and
turns
out
that
12
volt
appliances
are
very
common.
The
24
volt
appliances,
like
light
bulbs,
aren't
so
common,
so
that
would
be
one
application
there
now
here
we
can
go.
It
could
be
either
going
up
or
down
right
step
up
or
step
down
right
at
the
current
design,
yeah
yeah.
D
So
the
next
steps
are
to
figure
the
that
PWM
controller
chip
that
I'm
using
right
now
is
it's
designed
to
do
like
buck
or
boots
or
buck
and
boost
on
like
two
seventh
circuits.
So
it's
either
figuring
out
I
guess
it
would
just
be
like
putting
switches
to
disable
one
motor,
the
other
or
finding
a
different
chip.
That
does
a
similar
thing,
but
this
one
he
was
was
the
only
one
that
had
a
really
fast
see
that
I
could
find.
D
D
The
Arduino
would
control
the
potentiometer.
The
reason
there's
this
chip
for
doing
the
also
oscillation
is
the
Arduino
doesn't
have
can't
produce
a
high
enough
frequency
to
to
us
step.
The
voltage
I
have
a
reasonably
valve
at
this
size
of
inductor,
and
so
you
can
use
the
Arduino
to
control
the
potentiometer
which
changes.
C
D
A
E
D
A
And
then
like
what
say,
when
we
turn
on,
is
there
like
the
potentiometer?
That's,
let's
see
this
is
their
provision
for
some
kind
of
a
knob
to
like
how
do
we
control
this
is
adjust
by
coders
they're
gonna,
be
a
knob
on
Arduino
or
something
to
turn
it
or
turn
the
voltage
up
and
down?
What's
how
does
this
look.
A
D
A
A
D
D
D
D
E
A
A
A
D
D
C
B
Curious
but
I
think
eliminating
their
do.
We
know
would
be
simpler,
as
I
would
think
that
they
are
doing
it's
easy
for
people
to
program.
But
if
you
want
to
make
CNC
millimole
open-source,
you
know
hardware
circuits,
it
seems
like
using
really
low
and
count.
Ics
is
required
for
that
and
just
figure
out
how
to
do
stuff
with
like
five
five,
five
timers
and
you
know
different
band
chips,
and
that
takes
a
lot
of
circuit
board
basic
its
problem.
I'm
not
familiar
with
this
circuit.
B
C
B
A
Yeah
different
ways
to
do
it,
so
that's
that's
a
long
discussion
on
words,
I
think,
oh,
you
got
a
really
take
a
look
at
case
by
case
because
also
you
can
build
your
own
simple
version.
Dose
of
Arduino
is
basically
the
microcontroller
chip
in
a
socket
that
would
allow
it
to
break
out
and
stuff
like
that,
so
yeah
yeah.
Definitely
so
yeah,
let's
see
if
we
can
prototype
this
see
and
see
how
this
works
for
me,
I
would
see,
let's
see
and
the
design
that
we're
using
exactly
as
like.
A
If
we
could,
could
it
be
an
experimental
case
for
let's
see
well,
no,
this
yeah
increasing
this
to
to
120
volts,
let's
say
and
then
rectifying
from
120
AC.
So
then
we
can
make
things
like
tower
supplies
for
the
3d,
printer
or
other
devices.
So
the
most
interesting
thing
would
be.
How
do
we
design
this
in
the
most
modular
way?
So
we
can
put
these
things
together.
But
yes,
that's
that's
a
longer
discussion,
oh
yeah.
Let's,
let's
see
what
what
happens
here
so
thanks
miles,
do
you
have
any
questions
or
anything.
D
D
D
A
D
A
A
It
definitely
that's,
that's
useful.
We
know
there's
some
functionality
to
prank
it
on
that,
and
we
haven't
really
worked
a
lot
with
those
kinds
of
workflows,
yeah
so
to
wrap
up
though
I
do
want
to
just
comment
briefly
about
policy
clubs
and
their
role.
So
so,
as
I
mentioned,
I'm
going
to
London
Ontario
this
for
the
Friday
Saturday
Sunday
workshop.
But
how
does
that?
Why
person,
clubs
and
how
does
that
look
in
general?
So
the
talent
is
that
clubs
do
a
quarterly
build
event
like
an
extreme
build
event.
A
So
we
design
and
kind
of
bring
the
physical
real-life
regular
thing
driven
by
the
mentors
of
the
club's,
so
there's
design
on
a
weekly
basis
and
then
there's
an
event
every
quarter
where
different
clubs
get
together
now
right
now
we
don't
have
many
clubs.
We
have
one
club,
okay,
so
I,
don't
know
if
we're
gonna
be
competing
against,
maybe
it's
against
time,
but
the
idea
was
to
every
quarter.
Do
a
do,
an
intense
build
and
we're
looking
at
the
cordless
drill
and
the
power
tool.
A
Construction
said
is
getting
that
I
talked
about
this
for
many
times
already,
but
I
think
the
team
and
Ontario
is
quite
excited
about
the
cordless
drill
and
spin
that
out,
along
with
Hiro
axle,
where
we're
doing
the
contributions
from
clubs
on
one
side,
but
then
the
general
public
on
hero
X,
which
is
the
crowd
design,
so
crowd
design
platform.
Where
are
some
of
the
main
skills
to
do
this
like
if
we
give
them
any
clubs?
A
So
here
I
stood
it's
the
crowd,
design
aspect
and
it's
funded
like
yeah,
so
you
can
involve
funders
and
clubs
can
fundraise
like
the
mentors
asking
their
local
businesses
or
ideally
focus
on
products.
Then
product
sells
like?
Can
you
actually
build
a
high
quality,
cordless
drill
that
that's
actually
a
marketable?
A
A
If
there
are
a
number
of
clubs
happening
all
over
the
world,
then
that's
good
news,
and
then
we
can
implement
more
of
the
product,
ecology
approach,
the
world
collaboration,
ecology,
approach
where
based
on
part
libraries,
so
you
know,
for
example,
like
here
on
the
right
hand
side.
Here
we
have
the
picture
of
the
d3d
PVC
frame.
We've
got
modules
that
we've
already
used,
but
idea
is
that
once
people
get
familiar
with
the
free,
CAD
workflow
of
using
part
libraries,
which
are
a
huge
part,
then
we
can.
A
A
There's
of
the
use
of
common
common
online
tools
like
Google
Docs
and
then
documenting
everything
on
your
work
logs,
so
that
if
there's
more
people
joining
the
team,
you
can
find
by
what.
What
do
you
find,
what
each
team
is
doing
and
then
the
allbeing
collaboration,
so
so
every
every
Club
would
would
set
up
its
own
world
clogged
with
with
its
members,
and
we
borrow
designs
from
each
other
based
on
common
libraries
and
we
can
find
everything
based
on
our
work
logs.
A
So
that
is
a
basic
seamless
way
to
develop
in
parallel
now
the
relationship
to
the
dev
team
so
we'll
continue.
The
dev
team
is,
as
always
and
I
think
one
one
big
thing
is
and
and
I
started
working
on
a
book
mentioned.
You
know
this
this
spring,
but
then
hitting
into
the
immersion
program.
I
got
pretty
much
waylaid
from
that
effort
into
organizing
that
and
now
trying
to
get
and
get
the
3d
printing
Enterprise
off
the
ground.
A
So
I've
been
kind
of
negligent
on
the
book,
but
I
do
really
try
to
make
it
a
priority
to
return
to
that
as
soon
as
possible,
because
I
do
believe
that
having
a
big
perspective
for
this
work
and
how
do
you,
collaborate
and
the
background
work
behind
this
kind
of
nature
of
open
product
development?
You
know
there's
a
lot
to
learn:
lots
lots
of
different
cultural
material.
There.
A
lot
of
people
are
not
familiar
with
so
so.
I
am
gonna
work
on
the
book
as
soon
as
I
get
it.
A
But
now,
with
the
3d
printers,
there's
there's
a
whole
package
there
and
that
is
like
you:
have
the
mini
PVC,
be
3d
or
or
a
regular
mini
version,
because
if
you
make
nested
frames,
they
cut
out
a
four
by
eight
foot:
steel
in
America,
the
frame
she
gets,
14
16
inch,
14
inch,
12
inch
frames,
12
inch
and
10
inch
frames
could
also
be
used,
but
they'll
be
more
DT
many
style,
but
that
is
important.
So
you
can
use
use
all
the
materials
when
we
do
CNC
cutting
from
steel
and,
of
course,
with
PVC.
A
You
can
talk
about
3d
printed
frames
from
plastic
will
be
workable,
but
that's
you
know
each
one
of
these
things
is
a
series
of
development
comes
together
with
the
the
filament
maker
and
plastic
recycling
to
do
different
things,
but
I
really
want
to
see
different
different
things
coming
off
the
production
line,
whether
it's
simple
parts,
clothing
bearing
holders
rubber
tracks
I
mean
there's
a
lot
of
potential.
But
but
the
fact
is,
it
takes
a
lot
of
development
to
develop
any
any
serious
product
or
like
the
cordless
drill,
or
anything
like
that.
A
It's
it's
major
work
on
on
the
development
side,
so
lots
of
work
there.
That's
the
basic
basic
ecology
of
collaboration,
adding
the
clubs
and
I
really
or
to
this
this
weekend,
Friday
Saturday
Sunday.
When
we
get
Williams,
that's
William
Neal,
who
is
an
early
replicator?
He
actually
built
a
brick
cross
a
long
time
ago
with
another
person
in
China.
So
that's
the
infamous
or
more
famous
China
replication
he
that
he
was
behind
that
within
some
other
people,
but
he
has
continued
to
work
on
all
I
see
ever
since
and
he's
you
know
he
has.
A
Posters
of
osc
in
this
classroom
is
at
the
London
International
Academy,
which
is
secondary
school,
but
yeah
look
forward
to
developing
that
relationship
and
getting
out
there.
So
we
build
the
3d
printer
in
the
first
day
and
then
then
do
today's
one
is
primarily
about
designed
in
part,
libraries
and
a
method
for
collaborative
development.
I'm
cat
has
been
a
last
day
more
about
the
how
to
operate
the
club's,
how
to
how
to
collaborate
as
a
large
team.
A
Once
many
people
are
getting
on
the
board
on
the
clubs
and
then
sending
out
some
initial
strategies
like
like
how
do
we
fundraise?
How
do
we
do
the
quarterly
build
events?
How
do
we
invite
others
and
make
this
work
take
off?
So
that's
it
on
now.
That's
that's
a
brief
overview
of
OC
club's
concept,
but
that
is
I
think
an
exciting
part
with
stewards
people
who
are
interested
in
in
different
parts
that
can
involve
their
students.
That's
definitely
definitely
a
good
way
to
go
so
we'll
see
how
that
goes
and
take
our
lessons
from
that.
C
A
Today
then,
we'll
continue
same
time,
so
2:00
p.m.
next
week
on
on
Tuesday
again,
so
thank
you,
everybody
and
thanks
for
your
contributions-
and
we
will
meet
again
next
week
by
that
time,
I'd
like
to
be
running
the
new
d,
3d
extruder,
with
a
fan
and
an
italian
arrow,
so
we
can
actually
start
producing
some
ever
higher
quality
prints
just
getting
into
what
we're
doing
right
now
is
just
really
defining
inequality
to
be
able
to
print
under
all
conditions
in
all
materials
fast
or
slow,
printing,
rubber
materials,
large
prints.
C
A
We
got
to
be
producing
that
not
just
talking
about
what
producing
the
plastic,
lumber
or
other
parts
that
are
doable
with
the
different
3d
printers
so
and
then
then
again,
moving
on
to
other
machines
that
use
3d
printed
parts,
because
after
all,
3d
printers
are
good
for
printing
parts
for
other
things.
So
it's
that's.
Why
we're,
starting
with
that
there's
a
tangible,
accessible
route
to
involve
more
people
as
opposed
to
starting
with
tractors
and
houses.
We
take
the
start,
OC
clubs
with
simple
3d
printers
that
can
get
a
lot
of
people
involved.
