I
know:
people
complain
that
the
sound
wasn't
good.
Sorry,
that's
all
we
have
and
my
computer,
the
speakers
going
out
too
bad
okay,
so
so
November
13
2018
team
meeting
we're
moving
along,
what's
happening
these
days,
nothing
much
except
for
a
kid
building
today.
So
actually,
today,
I
received
a
package
from
Sarah
from
the
California
team
and
I
will
be
testing
the
build
of
a
kit
so
we're
starting
to
sell
kits.
A
If
you
go
to
microfactory
that
open
source
ecology
that
org
were
beginning
on
the
kits
sales
and
we're
testing
these
kits
out
to
make
sure
they
all
work.
I'm
gonna
do
a
certification
build
today
to
certify
Sarah
to
be
able
to
produce
kits.
So
that's
that's.
What's
going
on
with
that,
the
current
build
takes
about
six
hours
to
do
and
the
mark
of
a
good
kid
is
that
all
the
parts
are
there
and
a
complete
successful,
build
up
to
a
perfect
print
using
the
3d,
Banshee
and
Mark
3d
print
can
happen
within
about
six
hours.
A
So
that's
my
duty
for
today,
I've
got
my
print
cluster
up
and
running
in
the
open
source,
ecology
her
headquarters
here.
Just
for
printers
I'm
actually
going
to
do
some
modifications.
I
will
continue,
I'll,
actually
re
remounting,
the
x-axis
and
a
different
different
configuration
so
as
you've
seen
this
construction
modular
set,
then
we
use
allows
us
to
mount
things
and
definitely
some
attaching
them
to
some
higher
mounting
on
the
axis
to
allow
for
higher
more
Z
space.
B
A
We'll
do
a
first
three
day:
training
where
we
train
people
on
free,
CAD
and
collaborative
literacy
to
function
as
part
of
the
bigger
team
or
the
mentor
leads
weekly
meetings
for
the
students
at
their
respective
secondary
school,
so
that
we
can
enhance
some
of
the
development
and
also
do
a
physical,
build
every
quarter's.
The
different
idea
is
to
do
an
extreme,
build
every
quarter
with
the
students.
So
that's
you
can
read
more
about
it
under
micro,
factory,
open
source,
ecology,
org
and
just
click
on
the
professional
development
link.
A
C
A
A
C
C
Some
of
the
newer
for
me
about
the
printers
was
pretty
helpful
on
that.
Actually
I
would
actually
I
think
it
was
stuff
this
here
announced
are
doing
about.
It
looks
like
they're
developing
more
detailed,
some
some
notes
on
construction
details
for
the
printer
or
something
rods
and
so
on
cutting.
It
looks
like
there's
some
attention
to
detail
and
keeping
the
rods,
because
I
assume
that
your
pre
producing
a
lot.
You
know
all
the
parts
and
you
and
you're
cutting
all
the
rods.
C
B
C
C
Cad
that
we
has
so
far
and
so
on,
but
it's
there's
a
lot
of
imprecision
and
everything,
but
the
the
distance
is
on
that
stuff
are
gonna
depend
on.
You
know
the
thicknesses
of
the
clamp
and
so
on,
but
it
can
adjust
the
thicknesses
up
the
clamp
according
to
what
the
rod
length
can
be
at
the
maximum
when
a
PVC
frame,
but
the
thickness
on
the
back
end
has
to
do
with
that.
C
So
I
seen
those
recognize,
surprise
I,
don't
I
couldn't
tell
that
the
dimensions
on
those
plastic
parts
matched
up
with
impale
or
metric
measurements.
They
just
seemed
to
be
some
very
accurate
parts
that
I
assume
they're.
That
way
for
a
reason.
Firstly,
the
holes,
but
actually
the
parts
in
general
are
not
exactly
you
know
an
inch
or
something
like
that
or.
B
C
B
C
If
it's
more
efficient,
somehow
you
can
eliminate
the
magnet
recesses
I
guess,
but
they
might
be
useful
for
other
things
and,
of
course
certain
parts
do
have
to
have
them
still
I.
Think
right.
You
still
attach
certain
things
via
the
magnets.
If
the
extruder
or
certain
options,
the
magnets
are
nice
for
optional
to
swap
things
out
easy,
but
with
the
PVC
clamp
it
could
reduce
or
make
other
parts
differently.
I
mean
it
would
simplify
by
I.
C
Guess
certain
parts
I
don't
know
if
that's
necessary,
if
there's
reasons
to
do
that,
there's
pros
and
cons,
so
I,
listen
stuff
about
that.
I,
don't
know
if
they
print
faster.
If
they're
simpler,
the
actual
STL
is
simplified
if
that
matters,
but
the
short
idler
also
wasn't
used
in
the
in
the
CNC
circuit,
also
I'm
working
that
I
think
so
what
I'm
just
gonna
eliminate
the
magnet
holes
so
that
that's
that's
as
simple
as
I
can
can
make
I
think
and
still
assembly,
though
the
have
all
the
bolt
holes
available.
C
As
we
said,
they
are
plastic
make
guesses.
This
part
I,
think
about
what
I
figured
1/8
I,
don't
know
how
flexible
1/8
inch
of
peeling
is
with
that
curve
above
the
pipe
flexible
a
days
and
some
of
these
other
the
other
spaces
like
the
notch
that
could
be
narrow.
That
could
add
some
flexibility
on
the
end.
You
know.
C
C
A
A
C
C
C
A
A
C
C
C
B
B
A
Just
to
guide
you
on
this,
a
little
more
so
when
you
do
the
depth
of
that
hole,
you
need
to
make
sure
that
you're
using
like
currently,
we
are
using
thirty
millimeter
bolts
right,
so
the
thirty
has
to
go
through
the
printed
piece,
the
carriage
or
whatever,
not
the
carriage,
more
like
the
idler
or
motor
piece
and
has
to
go
in
there
has
to
end
up
within
a
nut
catcher.
So
you
just
remember
that
this
has
to
go
through
a
an
axis
piece
and
it's
a
thirty
millimeter
bolt.
So
were
you
aware
of
that?
Yeah.
C
Bolts
yeah
back
of
any
axis
yeah,
it's
got
to
go
through
yeah
the
access
holes
are
available
or
in
some
cases
it
has
to
go
through
holes
in
relation
to
the
motor
side.
That's
a
little
more
complicated
because
that
requires
I
was
looking
at
some
pictures
that
I
you
posted
earlier
of
some
of
that
and
I
notice.
You
don't
use
you're,
not
even
using
hex
and
bolts,
necessarily
and
so
on.
So
the
the
nut,
catcher
technically
doesn't
matter,
but
it's
a
good
thing
to
have
there
there's
an
option,
but
you
have
to
look
it.
C
It's
gonna
be
hard
to
figure
out.
They
like,
because
I
I
think
that
some
of
those
bolts
I,
don't
know
that
it's
the
bolt
that
go
through
the
motor
it
sits
on
the
z-axis,
since
the
motors
are
all
the
prayers.
You
know
just
put
the
motors
at
the
top
I
noticed
instead
of
the
bottom,
which
I
think
works
out
better
for
various
reasons.
C
A
I
mean,
ideally,
there
are
we'd
one
yeah
yeah
use
one
of
the
bolts
that
we
have
so
a
30
millimeter,
so
try
to
make
it
fit
a
30
millimeter,
so
maybe
a
recess
the
they
put
like
us
part
of
a
nut
catcher
on
top,
but
we
need
130,
millimeters
and
currently
like
measuring
what
you
have
you
have.
Let's
say:
you've
got
about
one
and
a
half
inches.
So
in
order
for
an
existing
bolt
of
it
and
you'd
have
to
maybe
like
make
that
hole,
location
closer
can
be.
A
C
C
C
C
A
A
C
C
A
Initially,
it
was
to
use
magnets
and
that's
still
valid,
I
mean
yeah.
We're
not
using
a
lot
of
the
magnet
holds
right
now.
It
doesn't
make
an
invalid
this.
You
can
still
mounted
magnetically
and
other
applications,
so
we're
we're
kind
of
working
with
the
universal
construction
set.
So
the
holes
there
are
still
useful
for
Magnus
yeah.
C
Happen
see
I
did
looking
at
some
more
Python
and
freaking
macro
stuff,
the
other
day,
cuz
I'm,
trying
to
figure
out
how
to
make
certain
things
faster.
That
way,
and
just
generally
trying
to
figure
out
how
I
use
certain
forget
functions.
Better
I
just
need
simply
to
work
Mitch
to
do
some
of
the
axes
stuff,
but
never
Li
run
into
problems
with
the
assembly
to
work
mention.
C
Ability
to
do
certain
operations
that
are
common,
like
simplifying
parts,
I
noticed
I,
think
that's
often
an
issue
for
a
lot
of
stuff,
like
I,
think
you
can
make
a
macro
that
will
hopefully
look
it.
You
know
some
part
they've
built
in
you
know.
I,
don't
know,
felt
the
slack
the
stuff
over
don't
be
able
to
figure
out
how
to
slip
the
parts
and
then
make
a
simplified
part,
because
there
is
a
function
built-in
to
free
cat.
That
just
makes
simple
copy,
create
simple
copy
on
the
heart
menu.
C
C
A
It's
not
it's
quite
impressive,
actually,
30
amp
max
current
DC
should
be
changed
from
anywhere
from
seven
to
sixty
volts,
then
put
an
output
changing
by
a
factor
of
two
part
part
cost
about
forty
five
dollars.
That's
interesting
and
then
we've
got
open
source
blueprints
for
that.
So
hopefully
we
can
get
this
thing
prototype
and
what
I
see
here?
Do
we
have
an
Arduino
here,
PWM
controller,
do
I
see?
A
Is
this
an
Arduino
or
not
really
doesn't
look
like
it's
an
Arduino
thing,
it's
a
PWM
controller,
so
using
specialized
chips
or
that
that's
good,
good
work,
no
more
updates
on
alignment
filmmaker
I
would
aim
for
a
bill
here
that
within
two
weeks
or
so
now,
let's
see
so
Jen's
on
online
here
so
Jen
any
new
thoughts
on
3d
printers.
So
last
time
we
talked
to
Jen,
we
were
discussing
some
issues
like
like
getting
in
for
like
home.
Schoolers
are
definitely
a
good
crowd
for
technical
education,
getting
teaching
people
about
prototyping
CAD
design
Arduino.
A
B
D
B
D
D
A
A
B
D
D
It
was
to
meet
the
Alaska,
the
needs
of
the
of
the
citizens
of
Alaska
and
and
I
think
primarily
homeschooling
through
the
state
has
been
for
like
so
the
state
doesn't
have
to
pay
to
provide
school
for
disabled
kids.
You
know
a
lot
of
just
sick
people
end
up
homeschooling,
but
it's
big
is
gaining
popularity
right.
A
D
D
D
D
Ii
hold
on
I
am
NOT
six
looking
how
to
do
it
legally
withdrawing
from
school
complying
importance
of
record-keeping,
yeah
they're,
just
saying
it's
legal
in
Missouri,
so
let
me
see,
let
me
try
to
urge
which
states
fun
homeschooling
enter
Alabama.
Oh
no!
Ok!
We
should
get
funding
for
homeschooling
a
different
state,
yeah.
A
A
B
B
A
I
know
school:
is
they
take
it
to
school,
alright
in
school,
so
yeah
so
I'd
like
to
actually
keep
this
meeting
short
today,
cuz
today,
I'm
doing
the
build
of
a
complete
kit
to
actually
get
the
video
over
the
full
build
in
six
hours
or
so
so
I
gotta
get
going
on
that
before
the
date.
I
think
that
was
a
way
so
I
think
you
know
get
some
good
updates
for
today
and
we'll
continue
going
so
yeah,
let's,
let's
plan
on
meeting
again
next
week.
A
At
the
same
time,
then
I
think
that's
that's
about
it
for
today,
unless
there's
any
other
pressing
and
we
got
a
share,
yeah
I
think
that's
it
so
in
two
weeks
going
to
London
Ontario
to
do
the
first
three
day,
merger
and,
of
course,
for
professional
development.
So
that
we'll
see
how
that
goes-
and
maybe
that's
a
template
for
doing
many
more
of
these
and
develop
Aussie
clubs
in
different
locations.
But
we'll
see
how
that
goes.
