A
A
So
just
a
few
things
and
seeing
what
we
can
organize
on
so
development
hours,
that's
working,
we've
got
please
continue
filling
your
hours
on
today's
agenda
is
continuing
this
saga
of
open
product
development
and
just
a
few
things
results
so
I'll
report
on
the
results
and
then
see
what,
where
else
we
are
with
Lex
and
habe
and
anyone
else
who
joins
so
3d
printer
major
point
of
development
still,
so
you
can
take
a
look
at
the
video
from
D
3d
version.
18
point:
oh
one!
That's
a
12-inch
version
of
the
3d
printer.
A
That's
I'm,
actually
sending
that
out
to
person
from
one
of
the
old
workshops
that
some
sample
prints
with
that,
but
I
think
the
12-inch
version
is
gonna,
be
the
one
that's
pretty
important
in
terms
of
it's
a
big,
bigger
machine,
more
powerful
and
so
forth,
so
that
it's
it's
a
better
product
in
general
and
can
allow
us
to
print
larger
things.
Just
for
us
where
we're
highly
interested
in
much
larger
things
like.
Let
me
share
my
screen
here.
A
Like
more,
you
know
more
industrial
scale,
things
up
to
printing
of
car
body
panels
and
glazing
and
plumbing
fittings
and
everything
else
up
to
structure,
possibly
some
plastic,
lumber
and
stuff.
But
that's
that's
where
we're
going
here,
that's
working
in
a
background
there,
there's
hegemon
and
in
Australia
he's
doing
a
replication.
His
machine
is
coming
out
really
nicely
I
mean
he's
he's
taking
some
good
time
to
do
it
check
that
out
very
nice
he
is
putting
in
the
time.
A
So
one
thing
he
did
add
to
the
system
was
actually
a
little
rubber
insulators,
where
the
bed
is
mounted
so
that
the
that
the
heat
doesn't
translate
to
the
printed
printed
parts,
which
is
actually
quite
good,
because
if
you
say
you
want
to
print
abs
and
you
have
parts
printed
out
of
say,
PLA
at
the
higher
temperature
for
abs,
you
might
get
melting
of
actual
parts.
So
pretty
nice,
but
I
mean
it
looks
pretty
impressive.
A
B
B
B
B
A
B
A
B
C
D
B
There's
shots
of
the
engine
there
and
it
looks
like
you
know:
there's
holes
there,
no
seat,
no
area
where
it
would
expect
the
air
to
come
out
that
I
can
put
the
cooler
that
wouldn't
interfere
with
the
starter.
In
fact
that
starter,
it's
cut
on
the
corner
there.
Next
to
the,
where
that
cooler
would
sit
so
I
just
assumed
that
you
bill
pull
that
out
of
there.
You
know
around
that
corner
of
the
frame
they
see.
A
A
B
A
Yeah
I
see
what
you're
saying
now,
but
in
practice
it
doesn't
work
like
that.
It's
I
mean
in
practice.
You
see
like
the
highest
pull
straight
in
front
of
the
the
big
hole
which
is
the
one
like
in
the
center
yeah
I
mean
it's
pulling
from
all
sides,
so
it's
kind
of
like
the
most
the
most
breath
you
get
directly
in
front
of
it.
It's
not
a
decide
if
you
put
at
the
side
you're
just
getting
like
tiny
amount
of
that.
B
B
A
B
A
A
A
Let's
see
no
I,
what
I
need
to
do
is
show
you,
the
actual
as-built
cuz,
the
ass
built
yeah.
It
was
actually
a
little
different.
We
used,
we
just
home-brewed
our
little
coupler,
because
we
just
used
like
a
two
inch
pipe
and
put
flanges
on
it.
Why?
Because
we
ended
up
cutting
down
the
shaft
of
the
engine
to
make
everything
shorter.
A
Like
you
see
in
your
CAD,
your
CAD
reflects
that
it's
see
how
long
that
coupler
is
well,
we
ended
up
doing
is
cut
like
an
inch
or
two
off
the
shaft,
and
we
only
had
like
one
and
a
half
inch
of
shaft
left
and
therefore
we
condensed
up
made
it
much
tighter
and
actually
I.
Think
your
power
cube
reflects
that
it's
a
little
too
long,
right,
yeah!
It
is
a
little
bit.
A
B
I
was
thinking,
is
we
have
all
these
fan
issues.
Yeah
I
know
some
of
that
pipe.
The
reason
to
make
that
sleeve
coupling
there
is
kind
of
expensive,
but
it's
just
a
short
piece,
but
if
that's
fairly
large,
it's
wonder
if
there's
a
way
we
get
that
motor
there.
Maybe
we
could
put
a
fan
in
there
like
3d
print
some
crude
thing
that
fits
on
that
coupler
inside
and
then
just
cut.
You
know
just
tore
some
holes
in
this
pipe
and
make
it
blow
our
hair.
Somehow
yeah.
A
B
A
B
B
A
B
A
B
A
It
should
be
I
mean,
should
be
sufficient.
We
should
be
good,
I
mean
we
should.
What
we
need
to
do
is
test
it
and
make
it
work,
cuz
I,
pretty
confident
it
would
work
and
then,
of
course,
ultimately,
you
go
to
the
actual,
build
and
running
it
for
a
few
hours
and
see
if
you
get
any
overheating,
but
I
think
it
should
be
good.
So
yep.
A
B
Come
in
and
gotten
this
kind
of
complex
thing
we're
trying
to
get
this
constraints
to
make
it
easier
to
change
things.
A
lot
of
you
know
certain
workflow
process,
but
that
also
adds
a
certain
amount
of
complexity
and
still
get
some
bugs
and
things
sometimes
I
was
having
issues
earlier.
It's
creating
some
of
these
parts
and
it's
not
an
immediately
obvious
in
your
process.
Flow
I.
Think
there's
some
complex
decision
tree
because
well
I,
say
bugs,
but
some
of
it
I
think
is:
there's
not
enough
clear
documentation
and,
of
course,
the
underlying
software.
B
There's
dad
enough
of
the
underlying
code
in
the
proper
order
to
use
the
constraints
and
things
well
enough.
Yet
so
it
there's,
you
know,
instructions
and
documentation
on
using
free
CAD
to
submit
to
this
way,
but
I
think
it's
thorough
enough,
so
it
can
be
I,
think
difficult,
maybe
to
edit
some
of
these
files
once
they
get
a
little
more
complexed.
B
A
Yeah
I
mean
the
idea.
Ultimately
it
for
any
construction
set
is
that
you
can
import
one
part
at
a
time,
which
means
that
so
say
you
have
the
palm
you
have
the
engine
and-
and
you
kind
of
are
supposed
to
work
from
somewhat
from
scratch,
because
the
idea
is
that
you
can
modify
the
frame
size
modify
the
arrangement
if
you
need
to
so
it's
more
important
as
long
as
we
have
the
library
parts
that
are
that
are
good
to
go,
then
it
should
be
workable
to
give
the
higher
level
design
from
that.
A
D
B
C
B
B
A
A
A
B
B
Usually
this
is
for
there's
a
part
where
I
found
it
easier
is
to
import
a
list
of
all
part
like
or
something
and
then
import
it
with
these
two
to
lock
it
so
that
it
can't
move
and
then
constrain
all
the
parts
to
that
one
locked
part.
So
it's
easier
to
not
have
to
move
around
in
strange
ways
strange
for
difficult
events,
so
that.
B
B
A
B
B
A
A
Separate
and
somewhat
important,
because
if
they're
an
inch
high,
then
you're
adding
an
inch,
and
you
have
to
consider
that
for
the
height
of
the
power
cube,
because
in
one
of
them
that
we
simply
were
too
tall.
And
that's
why.
That
was
part
of
the
reason
why
we
had
to
put
in
one
of
the
power
cubes
the
cooler
on
top.
Because
once
the
engine
was
raised
by
the
feet,
they
would.
A
A
Pretty
consistent
and
then
the
only
other
thing
I
would
call
out,
for
is
a
part
library
dedicated
to
hydraulic
fittings.
That's
one
of
those
things
that
we
always
pick
from.
So
for
the
the
hydraulics
construction
set.
You
want
to
have
all
those
parts
readily
available,
because
that's
a
very
distinct
and
clear
part
of
of
just
about
any
other
heavier
mech
panicle
devices
we
always
used.
You
know
these
valves,
these
fittings
these
hoses.
A
So
maybe
you
can
start
I,
don't
think
we
have
a
hydraulics
library
if
you
can
start
that
and
maintain
that
that
would
be
very
useful,
just
like
Islamic,
so
actually,
Ruslan
has
been
working
on
the
pipe
just
regular,
pipe
and
fittings
more
like
PVC,
PVC,
pipe
and
fittings,
so
that's
also
in
common
use.
So
if
we
get
one
for
hydraulics,
that
will
be
a
good
piece
of
a
construction
set.
A
B
A
Right
and
yeah,
as
far
as
you
know,
as
far
as
like,
when
we
get
this
thing,
pretty
detailed
I
mean
I
can
actually
you
know
well,
actually
the
best
workflow
on
this
power
cube
would
be
so
right
now,
probably
in
a
week
or
so
I'll
get
back
down
to
the
workshop
and
start
working
with
a
torch
table.
It's
really
cold
here,
right
now,
but
I
think
what
we
want
to
do
is
once
this
is
all
finalized.
A
Some
simple
cuts-
and
you
know
on
the
torch
table
or
just
assembling
this,
so
we
can
verify
to
the
minor
detail
because,
because
I
think
we're
very
close
to
a
power
cube,
that's
you
know
we
can
really
crank
them
out
now.
Just
you
know,
I'm
thinking
I've
been
so
as
I
mentioned.
I'm
writing
a
book
on
to
drop
the
knowledge,
but
in
it
I'm
thinking.
Okay,
what
does
a
160
horsepower
horse
truck
160
horsepower
tractor,
look
like
where
you're
getting
to
like
d6
d7
scale
of
bulldozers
and
stuff
like
that
cat,
b7
and
10
power?
A
Cubes,
that's
what
it
takes
so
it'd
be
like
a
whole
battery
of
a
minutes
sounds
kind
of
crazy,
but
if
each
one
of
them
is
simple
enough,
like
a
leaf
on
a
tree
by
biomimicry,
it
does
make
sense.
It's
like
when
every
unit
is
so
inexpensive
and
easy
to
maintain,
then
it
does
make
a
lot
of
sense
like
you
know,
instead
of
a
breakdown
and
cost
you
thousands
of
dollars
or
you
have
to
replace
an
engine,
you're
just
snapping
out
one
of
these
units,
which
it
could
be
very
promising.
B
B
A
No,
actually,
that's
those
are
the
hydraulic
motors
see
each
one
of
the
hydraulic
motors
that
we
currently
use
as
the
standard
high
traction
motor
is
it
can
handle
actually
up
to
40
horsepower,
meaning
that
each
one
of
those
motors
can
handle
a
couple
of
power
cubes.
That's
that's
what
I
meant
by
that.
So
okay,
currently
they're
the
hydraulic
motors
on
the
wheels
they
can
take
more
power
than
a
single
power
cube,
has
so
like
two
and
a
half
power
cubes
per
motor,
but
a
good
version
that
I've
been
thinking
about
is
okay.
A
You
use
the
same
tracks
the
exact
same
tracks
that
we've
used
on
micro
track,
which
are
way
over
built.
They
have
1
and
1/2
inch
track
pads.
They
have
well.
We
have
designed
them
with
the
large
motor,
but
you
can
put
up
to
well
each
one
of
those
tracks
put
four
of
those
tracks
on
a
much
bigger
machine,
and
then
you
have
a
very,
very
powerful
tractor,
so
basically
a
supersized,
basically
the
same
modular
element
as
the
micro
track,
but
four
of
them
four
of
the
track
units,
as
opposed
to
two
and
each
track
unit.
A
If
we
want
to,
we
can
drive
it
with
up
to
two
motors,
like
one
one,
on
each
side
kind
of
the
same
high
track
configuration
but
to
drive
motors,
so
you
can
using
the
same
design
pattern.
You
can
make
some
super
heavy
traction
machines
and
we're
talking
about
cat
d6
d7
territory,
which
is
up
to
three
using
okay,
so
the
numbers
are.
The
calculations
are
using
eight
of
our
hydraulic
motors,
we're
up
at
28,000
pounds
of
traction,
that's
pretty
serious
or
at
four
for
motors.
You
know
for
tracks
for
motors,
for
about
fourteen
thousand
pounds.
A
So
that's
we're
talking
about
scaling.
The
same
system
is
on
a
tiny
micro
track
to
a
huge
machine.
So
that's
that's
the
that's
the
idea
there
and
that
is
quite
exciting,
because
and
I
think
we're
gonna
have
to
do
that
this
year.
If
we've
got
the
torch
table
running,
we
can
build
all
the
power
cubes
we
can.
We
can
do
that.
So
probably
I
would
consider
putting
that
on
on
this
schedule,
for
like
October,
not
October
like
August,
or
something
like
that
whoa
and
a
smaller
power
cubes
prototype
of
that
little
earlier.
A
B
A
A
we
know
we
have
Shane,
who
is
in
the
background
working
on
on
the
CNC
circuit
mill,
we're
meeting
at
3:00
p.m.
so
for
anyone
who
wants
to
stay
after
this
meeting
you're
welcome
to,
but
anyway,
let's
go
on
to
the
next.
So
maybe,
let's
see
13
inch
frame.
This
is
awesome.
That's
you
talk
a
little
bit
about
it.
A
C
A
Very
good
Oh,
interesting
so
yeah.
If
anyone
wants
to
look
at
my
screen,
I'm,
looking
a
look
at
the
file
right
now,
yeah,
that's
pretty
good,
so
that
the
idea
here
was
this
is
updated.
So
I
believe
this
is
the
first
actual
as
built
CAD.
We've
we've
thrown
around
many
of
the
versions
of
the
machines,
but
a
lot
of
them.
We
never
really
had
a
fully
updated
one.
A
A
But
I
guess
it
would
be
more
secure
like
if
it
wants
to
fall
down,
it
can't
fall
down.
If
it's
the
other
way
around,
can
you
just
flip
it
and
switch
it
right
over
or
because
we
should
definitely
reflect
that
as
the
preferable
method,
because
I
mean
if
that
screw
gets
loose,
that
the
extruder
plane
falls
out,
whereas
the
screw
gets
loose,
it's
much
harder
for
it
to
fall
out
of
the
the
holder.
This
part
right
there,
if
that
is
the
stand,
is
on
the
bottom,
like
the
platform
is
on
the
bottom.
C
A
Okay,
well
I'm,
also
looking
at
let's
see
so
so.
The
extruder
in
these
designs
here
is
facing
the
actual
orientation.
If
you
have
the
standard
OS,
the
orientation
director
is
facing
back
and
the
Y
motors
are
at
the
back
so
I'm
looking
at
as
as
my
in
my
screen,
that's
the
correct
orientation.
The
end
stop
on
the
left
side
for
the
X,
the
end
stop
on
the
outside
for
the
Y
and
no
and
stop
on
Z
everything
else
pretty
much
I
guess
it
looks
pretty
good
to
me
the
yes.
C
A
A
C
A
Okay,
so
it'd
be
good
for
a
start
to
draw
that
detail
in
that'll
be
good,
so
we
have
a
completely
accurate
detail
and,
let's
see
the
next
question
that
I
would
ask
for
is
what
are
we
getting
as
far
as
the
usable
print
bed
area,
because
I
know,
we've
got
some
constraints
on
that
we're
not
using
the
8
by
8
right
now.
What's
do
you
have
some
data
on
that.
E
A
A
So
that's
why
we
have
the
axes
on
the
outside
to
get
more
of
the
usable
area,
but
actually
we
also
have
the
axes
on
the
outside
on
a
12
inch
version
where,
with
axes
outside,
you
can
use
the
12
inch
area
on
the
larger
machine
with
a
16
inch
frame,
but
what
we
can
do
here.
So
let's
talk
about
this
for
a
couple
of
changes
so
on
the
X
axis,
you
can
get
yourself
a
little
bit
more
room
if
you
put
spacers
underneath
the
axes.
A
Do
you
see
that
so
the
four
attachment
points
you
can
put
spacers
in
there
and
therefore
get
up
to
the
full
eighth
inch
of
the
bed?
And,
that's
probably,
you
know
I
guess
how
important
is
that
for
somebody
I
mean
it
definitely
helps
to
get
eight
by
eight
inches,
as
opposed
to
like
six
by
six
and
a
half
like,
for
example,
on
printing
the
filament
maker,
there
were
parts
that
you
needed.
The
eight
inch
bed
fully
for
the
filament
maker,
the
Lyman
filament
maker
as
an
example,
and
typically
the
eight
by
eight
is
the
standard.
A
So
a
lot
of
parts
might
assume
that
you
might
have
an
eight
by
eight
perhaps,
but
that
would
be
I
would
say
that
would
be
worthwhile.
That
would
be
quite
simple.
You
can
put
just
little
I
mean
you
can
use
washers
as
spacers,
but
the
only
thing
is
you
would
need
longer
longer
bolts
which
you
might
not
have.
A
You
can
use
threaded
rod
as
an
example,
but
what
we
want
to
do
to
make
this
official
is
to
I,
probably
like
for
the
official
release
like
we
do
want
to
go
to
the
eight
by
eight
inch.
So
therefore
draw
in
you
could
do
3d
printed
pieces,
but
it's
it's
pretty
easy
to
do.
If
you
just
do
little
washer
spacers
like
a
bunch
of
little
washers,
though
they
tend
to
fall
off
or
just
larger
nuts,
so
what
we
want
to
do
is
select
okay.
How
do
we
get
that
spacing
happening
there?
A
Is
it
gonna
be
a
3d
print?
Do
we
just
want
to
I
mean
another
way
to
do?
It
is
actually
put
nuts
washers
and
nuts,
where
the
nuts
are
actually
clamping,
so
you
have
empty
threaded
rod
as
the
spacer
like
the
the
bolt
itself
could
be
as
used
as
a
spacer,
because
it's
plenty
strong,
like
a
little
quarter-inch,
Baltus
or
six
millimeter
bolt,
is
plenty
plenty
strong
to
do
the
extension.
A
So
that's
actually
one
way
to
do
it,
and
maybe
that's
perhaps
the
easiest
one,
because
you're
just
using
the
bolt
that
you're
using
anyway
but
you're,
using
like
two
more
nuts
to
to
hold
the
the
axis
at
the
as
far
distance
as
you
like.
In
fact,
if
you
used
threaded
rod,
you
can
make
that
spacing
larger,
larger
and
larger.
To
the
point
that
if
you
imagine
that,
if
you've
got,
you
know
right
now,
you
got
like
six
inches.
A
A
Maybe
if
you
can
select
like
a
standard
part.
So
this
is
not
guesswork.
This
is
replicable,
select
a
standard
part
of
mcmaster-carr
or
some
other
source.
Where
you
show
exactly
what
that
length
of
that
bolt
is,
and
it
can
be
some
random
length.
It
has
to
be
a
bolt.
That's
or
scible
like
it
can
be
like
23
millimeters.
It
might
have
to
be
25
millimeters
because
they
don't
make
23
millimeter
bolts.
Unless
you
go
special
order.
A
C
A
So
we
address
the
x-axis.
Now,
let's
move
on
to
the
y-axis,
it's
a
little
more
tricky
there,
because
we
don't
have
as
much
play
there,
but
what
we
can
do
is
if
you
observe
the
the
rear
left
Y,
where
the
motor
is
with
the
end,
stop
you
can
gain
yourself
about
one
one
inch
or
one
and
a
half
inches
mm.
If
you
bolt
it,
let's
see
you
don't
have
the
book.
Okay,
so
I
would
like
well.
A
I
would
like
you
to
definitely
do
add
to
this
CAD
this
the
exact
bolt
holes,
because
then
we
can
get
those
bolt
holes,
CNC
cut
and
that's
that's
all
comes
in
a
kit,
but
here
you're
not
showing
the
bolt
holes.
But
if
you,
instead
of
the
the
outer
bolt
holes
like
towards
the
end
of
them,
the
axis
used
the
inner
bolt
and
right
there.
You've
earned
yourself
about
an
inch
or
more
than
an
inch.
It's
it.
That's
like
that
spacing
between
two
bolt
holes,
yeah,
so
so
move
it
over
one
bolt
hole.
C
A
Very
good
point-
and
that
brings
us
to
the
following
plan.
Then
we
know
that
the
Prusa
i3
extruder
is
different
and
it's
it's
part
of
its
advantages
that
takes
us
less
space
like
right
now.
We've
got
we're
taking
up
a
lot
of
space,
probably
like
one
or
two
more
inches
than
we
need
the
Prusa
i3
extruder
is
actually
much
more
flat,
so
that
will
gain
us
an
inch
or
two
there.
So
maybe
the
procedure
would
be
as
you
develop
this
one.
A
You
can
well
I
mean
the
CAD
you
can
do
anytime,
but
as
far
as
the
real
build,
what
I
would
maybe
focus
on
is
is
do
the
you
know
after
this
meeting,
I
would
actually
recommend
to
go
to
the
Prusa
i3
experience.
That's
a
priority
for
everyone
like
I,
want
to
retrofit
it
to
my
machine
here.
So
maybe
work
on
that,
but
with
that
you're
gonna
gain
yourself,
the
the
y-axis
motion
a
little
bit
and
then
on
the
other
side
the
way
you
have
the
short
piece
there
yeah.
A
A
A
Sorry
I
know
why
yeah
to
extend
the
x-axis,
you
put
the
spacers
on
the
wife
to
widen
out
the
space
between
the
Y's.
You
can
also
do
the
same
for
the
Z's,
the
people
spacers
underneath
those.
Then
you
can
gain
yourself
like
an
inch
or
two
where
the
Z
motor
is
mounted
on
where
the
motor
is
interfere,
so
you
could
yeah,
so
you
could
gain
one
inch
like
say
one
and
a
half
I'm
hoping
for
like
one
and
a
half
inches
from
the
extruder
upgrade.
Let's
see
what
it
is.
A
A
C
A
Yeah
this
Mountie
I,
don't
like
it
it's
a
little
unstable
and
I
know
that
when
a
machine
gets
really
hot,
sometimes
you
can
the
the
plastic
there
actually
can
warp
and
the
probe
can
bend
a
little
mean
twist
a
little
slightly
and
then
it
doesn't
sense
as
well
and
the
other
thing
actually,
since
that's
been
a
recurring
issue
like
that,
the
gap
that
we
have
right
now
between
the
and
you
have
that
pretty
accurate
yeah
between
the
nozzle.
It's
about.
Typically,
we
have
the
probe
about
one
millimeter
higher.
A
Would
you
say,
is
that
about
right
or
it's
about
a
millimeter,
but
that's
actually
very
tight
I
mean
sometimes
the
I've
had
the
probe
hit
the
work
pieces
here
and
there
especially
like
if
you
get
some
some
misprint
and
something
sticking
out,
it's
very
easy
for
the
probe
to
hit,
because
it's
right
above
the
print,
it's
very
tight.
So
what
I
would
actually
suggest
and
I
think
it's
a
good
idea
go
from
the
four
millimeter,
which
is
what
we're
using
I
think
it's
called
a
four
millimeter
probe
like
it's
a
tiny
one.
A
Well,
four
million
meters,
sensing
distance
I
think
we
want
to
go
to
the
slightly
fatter
one,
which
is
the
eight
millimeter
sensing
distance
one.
Some
people
use
that
and
I've
heard
that
being
used
to
give
more
clearance
to
the
to
the
printbed,
we're
using
an
aluminum
bad,
which
is
less
sensitive
than
than
metallic,
like
iron
metallic.
A
So
that's
why
you,
the
probe,
gets
so
close.
It's
supposed
to
be
four
millimeters
away,
but
it's
really
about
one
millimeter
after
you
count
in
the
PEI
surface
printing
surface,
so
I
would
suggest
so
Roberto.
Maybe
if
you
could
try
when
you
modify
the
Prusa
i3,
you
can
try
with
the
existing
extrude
the
existing
probe,
but
I
would
actually
do
both
do
one
for
the
4,
millimeter
probe
and
then
look
up
the
one.
A
That's
that's,
got
eight
millimeter
sensing
distance
and
gonna
be
a
little
wider
and
put
that
in
there
as
well,
because
I
can
tell
you
that
this
four
millimeter
sensing
probe
is
gonna
work
well
with
when
we
have
steel
and
steel,
maybe
what
we
use
for
larger
machines,
because
steel
is
very
inexpensive,
but
for
now
we're
definitely
using
aluminum
for
in
part,
because
the
of
the
aluminum
printbed,
which
is
integrated
with
the
heater,
the
heater
print
bed,
is
aluminum.
So
that's
that's!
A
That's
what
you
get,
but
when
we
go
to
making
our
own
heat
beds,
we
can
definitely
consider
steel,
which
is
heavier
but
cheap
way
cheaper,
like
three
times
or
so,
cheaper,
which
means
you
can
get
much
lower
cost
larger
scale
machines.
When
we
talk
about
one
meter,
print
bed
size
that
kind
of
size,
so
yeah
I
could
have
you
do
both.
That
would
be
great
for
the
brew.
So
have
you
looked
any
into
the
Prusa
extruder.
C
C
C
A
A
Yeah,
that's
good,
no
I
think
I
think
the
answer
to
Roberto
is:
we
should
go
with
the
filament
sensing.
That
is
very
useful.
If
you
I
mean
you're
you're
doing
a
long
print
and
then
it
just
crowd
it
just
messes
it
up,
because
you
ran
out
right,
ran
out
of
filament.
That's
very,
very
useful
I
mean
especially
for
large
jobs.
So,
let's,
let's
go
up,
go
with
the
latest
version.
Is
that
are
those
parts
available
for
the
latest
version
or
they're?
Not
yet
do
you
know.
C
A
Let's
do
that.
Can
we
do
that
yeah?
Let's,
do
that,
let's,
let's
get
updated
with
the
latest
Prusa
i3,
and
this
is
the
way
that
open-source
works
I
mean.
Hopefully
we
can
make
that
work
for
us
by
building
upon
what
they've
done,
which
is
good
and
they
definitely
have
a
good
extruder.
So
but
it's
not
three
millimeter
which
we
were
will
want
for
later
for
larger
prints.
So
that's
that's
what
you
get
okay,
that
sounds
good,
so
Roberto
do
you
have
enough
to
go
on
for
now.
A
Yes,
excellent,
well
good
work
here,
so
yeah
we're.
That's
definitely
like
the
13
inch
version
is
important.
The
16
inch
is
the
largest
of
like
when
you
have
a
48
inch
sheet
of
metal,
the
16
inch.
That's
why
we
selected
16,
so
you
have
zero
waste.
So
16
like
three
of
those
four
it
fit
across
a
sheet
of
metal,
that's
standard
in
the
United
States.
Then
we
have
the
nested
frames
great.
Let's
move
on.
A
D
A
A
A
D
A
A
12
order,
it's
3
$29
for
a
1
order.
It
might
be
like
500
I,
don't
know,
but
you,
if
you're
willing
to
wait,
you
can
get
it
for
like
300
$29,
you
get
it
off
places
like
Aliexpress
yeah.
It's
not
all.
It's
not
a
lot.
It's
it's
pretty
decent,
but
you're
gonna
have
to
have
somebody
print
you
some
parts,
the
printed
parts,
I
think.
D
A
Yeah
yeah
I
mean
many
of
them.
I
mean
you
can
do
it
for
cheap
if
you
scrounge
parts,
but
we're
saying
like
the
three
$29,
that's
for
a
pretty
replicable
version
that
you
can
be
sure
you
source
all
the
parts
without
variation,
so
yep
yep
all
right.
So,
let's,
let's
move
on
to
to
Josh.
Maybe
since
you
typed
up
there,
any
updates
on
micro
tract
updates.
D
A
D
A
D
D
A
Well,
just
one
update.
So
since
the
since
the
workshop
happened,
we
did
some
field
testing.
One
thing
I
discovered
was
that
the
tilt
the
curl,
the
dump
of
the
bucket
is,
was
to
look
too
small.
It
was
like
30
degrees
or
so
so
I
actually
changed
the
pivot.
The
top
cylinder
attachment
on
the
quick
attach
plate,
I
put
it
closer
to
the
bottom
points.
A
Is
that
such
that
the
cylinder
is
making
it
move
at
a
larger
angle,
so
it
now
dumps
pretty
much
vertical
so
that
took
closing
in
the
top
hole
by
about
like
I,
think
two
inches
I
moved
it
in
so
I
can
take
a
picture
of
that.
So,
instead
of
that
separation
being
like
whatever
we
had
like
10
inches,
it
might
be
like
8
inches
now.
So
that's
that's
a
major
shift
as
far
as
the
design.
Beyond
that,
it's
pretty
much
pretty
much
the
same.
So
that's
that's
something.
A
A
The
same
for
the
arms
no
need
for
the
extra
pieces
when
you
could
put
cut
it
all
out
of
the
same
piece
when
it
came
down
to
reality.
We
just
weren't
prepared
enough
to
figure
that
out
before
the
event,
so
ya
know
we
want
to
just
pretty
much
raise
the
arm
geometry
a
little
bit,
so
we
don't
have
to
add
those
pieces
there
already.
The
holes
are
gonna,
be
within
the
arms
yeah,
okay
yeah,
but
we
wanted.
We
do
want
to
document
this
for
the
sake
of
yeah.
A
Just
getting
you
know,
making
sure
we
have
this
complete
model,
even
though
it's
you
know
like
a
lot
of
them
like
I,
don't
think
we're
gonna
suggest
anybody
build
those
loader
arms,
but
since
we
have
that
I
think
it's
it's
it's
good
to
have
that
in
CAD,
because
then
we
can
do
you
know
as
we
test
it.
We
can
work
with
the
CAD
and
figure
things
out
and
stuff
like
that,
so
so
I
mean
all
together.
It's
it's
quite
pleasing,
I
mean
the
the
results.
D
A
The
part
about
turning
is
difficult
as
that.
That's
one
shortcoming
of
this.
If
you
like,
once
I
put
on
the
button
put
on
the
bucket
with
a
full
load
of
soil,
it
is
hard
to
turn,
whereas
we
didn't
see
that
in
during
the
workshop,
because
we
could
spend
circles,
but
that's
because
we
didn't
have
the
loader
arms
on
and
no
weight
on
a
loader.
So
we
could
really
turn
that
thing
around
in
place.
So
what
to
do
about
that?
What
I'm
thinking
for
the
next
version?
A
We
can
gain
just
a
little
bit
by
decreasing
the
size
of
the
drive
sprocket.
We
can
go
from
like
the
current
8
8
tooth
down
to
like
16,
and
it
would
still
probably
work
well,
so
you
would
gain
ourselves
like
30%,
more
more
torque.
So
that's
one
way
to
do
it
other
than
that
I
mean
we
keep
on
stalling
out
upon
the
max
torque.
So
another
potential
thing
to
do
is
to
reduce
the
pump
even
further
to
get
more
torque
out
of
a
smaller
pump
that
will
never
stall
cuz.
A
It's
caused
engines
got
more
power
that
might
get
us
to
a
higher
psi.
So
I
think
I'm,
hoping
that,
with
the
smaller
drive
sprocket,
we
can
get
that
30%
will
be
enough
to
make
ourselves
really
comfortable
with
a
turning
because
right
now,
yes,
in
tight
spots,
I
mean
when
you're
an
open
ground.
It's
not
an
issue
just
take
a
little
more
space
to
turn.
A
You
want
to
just
do
it,
so
definitely
that
part
is
is
desirable
and
beyond
that
I
mean
that
other
things
we
can
try
mean
the
machine
is
way
over
built,
as
it
is
right
now,
with
a
half-inch
thick
tracks,
I
mean
we
can't
potentially
lighten
up
some
of
the
structure
to
make
a
lower
weight
machine,
in
which
case
the
the
hydraulic
motor
would
probably
be
more
than
enough,
but
right
now
the
machine
is
quite
heavy.
So
we
can.
We
can
work
on
optimizing
that
but
I'm
hoping
that
a
smaller
drive
sprocket
will
do
the
job.
A
D
A
A
A
E
I,
don't
really
have
an
update,
I'm,
still
kind
of
getting
back
into
into
things
from
the
holidays.
Yeah
I'm
really
excited
about
getting
my
boots.
The
next
one
so
I've
been
you
know
doing
a
lot
of
research
and
figuring
out
the
thing
all
the
exciting
things
I'm
going
to
print
yeah.
Also,
who
you
printed
stuff
that
you
guys
are
doing
so
I
mean
I'd
like
to
my
first
task,
is
gonna,
be
to
replicate
the
piece
of
boots
that
to
make
the
OEC
printer
right.
A
They'll
be
very
cool
and
then
I
mean
I
would
suggest
that
the
high
priority
there
is.
The
extruder
is
the
weak
point
in
the
whole
system,
so
I
would,
depending
on
where
Roberto
is.
At
that
time
we
want
to
really
nail
the
extruder
part,
because
that
gets
us.
So
after
the
prusik
extruder
is
gonna,
be
the
3
millimeter
extruder,
which
then
we
can
print
rubber
and
other
things,
because
I
mean
a
practical
thing
that
we
could
be
doing.
A
Is
things
like
rubber
tracks,
for
the
tractor
I
mean
that's
practical
I
mean
we'd
have
to
have
access
to
low-cost
printing
filament,
which
right
now
would
be
unaffordable,
but
once
we
do
the
filament
maker
and
we
can
go
from
rubber,
scrap
thermoplastic,
elastomers
scrap
and
we
can
talk
about
practical
ways
to
print
things
like
rubber
tracks
and
other
things
so
yeah.
We
definitely
want
to
go
forward
on
the
extruders.
E
A
Limon
could
probably
do
it
while
Lyman
has
optimized
the
way
he's
got
it
working
with
ABS
right
now,
I'm
sure
you
can
do
something
with
it,
but
it's
it's
a
matter
of
figuring
it
out
figuring
out
all
the
details
of
how
to
do
that
properly
and
then
for
the
Thunderhead
film
and
extruder,
the
more
advanced
one
yeah
that
could
that
could
handle
it.
The
advantage
there
being
just
get
higher
throughput
through
the
Thunderhead.
So
maybe
the
alignment
could
be
like
a
low
lows:
low
brow,
entry
level
model
where
we
can
produce
some
filament.
A
But
if
you
want
to
run
an
enterprise
actually
producing
filament
for
others,
you
probably
want
to
go
to
a
bigger
one,
but
that's
all
to
be
determined,
but
we
do
know
that
the
the
more
advanced
one
is
God
just
way
more
throughput.
So
for
larger
things.
Yeah
I
probably
want
to
use
the
larger
larger
one,
but
that
would
be
a
very
cool
Enterprise
to
open
source
that
open
source
printing
filament
and
then
the
whole
print
cluster.
Like
we
talked
about
all
of
that,
okay
I
think
we're
wrapping
up.
A
We
have
a
meeting
coming
up
with
Shane
who's.
Gonna
join
us,
so
I
think
we
can
wrap
this
up
right
now
and
see
you
guys
next
week
continue
the
work
I'm
working
on
a
book
I'm
working
on
putting
together
some
assets,
I
mean
continuing
working
on
a
3d
printer
and
then
torch
table,
so
I'm
pretty
busy
really
trying
to
but
I
do
want
to
bring
up
the
topic
of
all
of
us,
collaborating
on
on
the
website
where
we
can
market
the
3d
printer.
A
So
I
suggest
that
you
all
you
kind
of
think
about
what
the
possibilities
there
are,
but
it's
huge
I
mean
its
possibilities
are
therefore
for
us
to
start
bootstrapping.
Some
cash
to
you
know
to
start
doing
this
on
a
more
full-time
basis
like
like
my
complaint.
Is
that
nobody's
doing
this
for
our
livelihood,
except
really
myself
in
katarina
right
now?
As
far
as
rep,
you
know
working
on
OSE
stuff,
full-time
and
getting
revenue
from
that,
and
we
use
the
workshop
model
to
support
ourselves.
A
It's
bootstrapping
workshops,
and
then
we
don't
really
produce
kits
right
now,
but
I'd
like
to
add
that
using
a
print
cluster,
where
we
work
that
all
out
in
detail
and
make
a
bunch
of
useful
useful
things,
you
can
have
certain
very
useful
objects,
like
cameras,
drones,
robotic
arms,
cordless
drills,
all
these
kinds
of
things
that
we
can
sell
as
kids,
educational
kits
and
real
practical
product
kits
for
people
to
as
marketable
products
yeah.
But
that
takes
all
development.
