Description
Existing state of OSE's CNC Torch table from Friday, June 6, 2014. We are using a gantry as this - http://opensourceecology.org/wiki/CNC_Torch-Router_Table_2_-_Gantry_-_3D_CAD - open the STEP file in FreeCAD.
We are using the Lasersaur open source CC-BY-SA controller - it has an advanced smart phone interface. The advantage is that it is a fully open source stepper controller - the only one we know of which can handle higher current (up to 7A and scalable to more).
The description above describes how to connect wirelessly to the torch table. The Lasersaur controller uses a Beagle Bone Black. Then we cover how we connect low-cost-stepper drivers (1/3 the cost of Gecko drivers).
The advantage of using the Lasersaur Controller is that we can use the same controller both for our Lasersaur laser cutter and for our CNC torch table.
Next steps include adding automatic gas control (cuttting oxygen gas turnon) for oxyacetylene cutting, spark igniter and capacitive sensing automatic height control. And perhaps a little trimming up of wiring.
A
Okay,
so
step
number
one,
you
need
an
access
point.
Wi-Fi
access
point
that
the
now
the
vehicle
bone
black
this
driver
board
here
this
little
computer
here
is
probably
going
back.
That's
configured
to
automatically
connect
to
the
Wi-Fi
with
the
name
ose
huts
and
the
password,
which
is
in
the
documentation
and.
A
Want
you
want
to
change
the
name
stuck,
there's
a
settings
file
on
legal
hold
back
and
you
would
connect
to
you
going
back
with
the
cable
with
the
ethernet
cable,
which
we
don't
happen
to
have
handy
here.
But,
like
you
know,
one
that
ends
in
this
rj45
connector
come
over
here
yeah
looking
over
there
and
you
can.
Then
all
you
have
to
plug
in
hey.
The
cable
goes
from
here
to
a
switch
or
a
rotor
and
then
from
the
switch
of
the
rider
you
plug
in
another
cable
goes
to
your
computer.
Well,.
A
And
a
half
here:
okay,
but
it's
a
switch
or
a
writer
seiki
Google
like
a
super-agent,
he
said
network
contributes
the
same
pc
working
with
you
and
then
you'll
go
to
local.
But
laser
sword
locals
sig
check
that
your
browser
and
it'll
do
a
dns
lookup
and
get
you
to
the
login
to
the
feasible
back.
And
then
you
need
to
ssh
into
the
BeagleBone
black.
So
like
putty
is
a
good
program
for
windows.
A
A
B
A
It
should
be
wpa2,
PSK,
show
you
the
security
settings
and
then
yep
that's
not
affect.
You
should
be
able
to
login
to
the
big
one
back
over
the
way:
I
great
UK
singer,
so
I
bargain,
if
you're
worried
in
that
part,
is
absolutely
all
that
you
see,
don't
remember
it
or
whatever
is
included
in
the
documentation
and
now
I've
turned
my
phone
into
a
Wi-Fi
hotspot.
This
is
a
standard
feature
in
android,
just
go
to
settings
things
and
you
go
more
settings
thething
in
portable
hotspot.
A
You
turn
on
portable
Wi-Fi
hotspot,
sorry
to
not,
and
when
after
Teddy
turned
on,
you
again
click
this
tap
on
the
same
area,
which
is
not
entirely
obvious
and
it
will
open
up
the
configuration
for
the
Wi-Fi
hotspot.
So
right
now
the
toe
device
is
connected,
but
it
tells
you
the
name
of
it,
says:
LC
ose
hubs,
oh
wow,
all
devices,
of
course,
and
you
can
go
configure
to
set
the
password
over
here.
A
Oh,
let's
see
bounce
okay,
we
just
go
changing
passes
through
anyway,
so
now
that
part
set
up
with
the
Wi-Fi
I
and
then
in
turn
on
the
Google
block.
So,
first
of
all
my
plugin,
here's
the
power
supply
for
it,
so
standard,
ATX
power
supply
and
it's
already
wired
up
Kari
can
see
the
Bible
positive,
like
sources,
sending
it
to
the
roster,
and
so
I
can
get
bug
this
in
and
then
we
also
plug
the
suburbs
in
the
one.
Is
it
there's
another
power
supply
for
the
second
order
system
to
play
for
hope?
Why.
A
Well
sounds
loud
when
you
turn
it
off
and
turn
back
against
enough,
so
you
can
see
a
little
light
below
you
see
the
light
over
here
on
the
stepper
motor
drivers.
That's
going
to
turn
off
and
okay
that
would
be
going
back.
This
is
also
another
par
switch
over
here.
It
was
off
and
on
you
can
hit
the
fan
turn
on
in
this
thing.
A
When
you
do
that,
and
we
got
to
give
to
be
going
back
like
like
a
minute
to
boot,
up,
it's
pretty
bad
faster
than
with
so
gonna
get
some
time
and
we'll
know
when
it's
done
or
sometime
after
it's
done,
because
it
should
appear
in
the
device
list
I'm
going
to
get
my
computer
to
connect
to
that
access
point
also
host
eat
up
here,
just
connect
unlikely.
You
should
have
the
password
it
already.
A
You
can
see,
there's
three
of
them
sure,
although
it's
only
controlling
two
sets
of
stuff
Mars,
don't
work
I
did
you
have
to
come
back
to
that
one
anyway,
ok,
I
know.
One
of
them
is
just
like
wait,
ok,
but
it's
supposed
to
use
a
different
staffer
motor
driver,
the
geckos,
but
we
tried
to
save
money
and
use
something
else,
because
the
geckos
are
70
bucks
and
these
are
twenty
bucks.
These
don't
have
any
data
sheets
for
them,
though,
and
they
have
a
different
pin
out.
A
So
we
can't
just
the
geckos
this
little
header
here.
These
pins
sting
out.
If
you
put
your
camera
like
down
here
like
real
low
till
it's
like
yeah
thought
you
there,
you
can
see
yourself
in
sticking
up,
and
this
is
a
public
terminal
block
header.
It's
you
tighten
down
each
one
of
these
screws.
Then
they
connect
to
the
pins
that
are
right
below
them.
Let's
go
a
little
clamp
on
there
and
then
to
the
back
here,
just
soldered
on
to
the
clamp
it's
a
wire.
A
You
don't
need
schematically
gecko,
you
just
plug
it
in
but
good
to
know
which
lawyers
you
don't
have
these
wires
to
exist
if
you're
using
cackle
the
geckos
they
just
plug
straight
into
the
bar
here,
ose
commas
yeah.
You
can
see
that
in
there's
pictures
of
that
in
the
documentation
to
look
later
on
also
zakiya
torch
table
they're,
just
little
red
boxes
did
little
bit
like
this
a
little
bit
smaller
in
the
red.
Actually,
we
can
go
actually
convert
some
of
those
drive
workers.
A
B
B
A
B
A
Like
the
whole
thing
is
called
the
dr
board
and
then
the
bball
doc
is
slow
computer
here,
okay
and
then
the
there's
an
arduino
here,
there's
an
88
to
mega
is
the
center
core
chip
at
the
heart
of
an
arduino
e.
There
are
Jimmy.
Allah
concludes
like
this:
the
oscillator
and
some
other
design
stuff
friend
instead
of
ulch.
It's
you.
That's
not
like
that.
Okay.
B
A
A
Now
we're
gonna
go
well,
you're
stuck
be
able
to
do,
is
connect
and
again
mazur
sore,
but
local.
That's
what
it
says
in
the
manual
for
the
laser
store
the
mag
spreads.
This
is
no
it's
doing
something.
I
would
it
work
this
time.
Okay.
Well,
it
doesn't
always
work.
So
if
it
doesn't
work,
you
just
get
the
IP
address
of
the
deagle
and
black,
which
is
you're
using
a
different
Wi-Fi
access
point
you're
going
to
have
to
have
some
of
the
way
of
figuring
out
the.
A
Not
always
easy
so
now
I
will
just
type
it
in
one
eye
to
what
one
six
a
dot
for
331
and
it
goes
again,
is
everything
okay,
so
I
should
load
the
Spade
cheers
as
laser
app
that's
a
little
JavaScript
or
Java
applet.
That
runs
your
computer,
so
it's
kind
of
easy
because
it'll
load,
even
if
you
can't
communicate
with
the
Google
ball
back,
because
your
browser
stores
the
Java
hazard
mm-hmm
right
now.
Okay,
so
it's
ready.
It
says
so
it's
connected
to
the
sergeant
communication
listed.
A
A
There
we
go
so
if
you
pledge
does,
is
it
moves
the
stock
more
all
the
way
until
it
hits
the
limit
switch,
and
then
it
moves
back
like
a
third
centimeter.
So
that's
the
noise
that
sometimes
disturbing
that's.
Why
supposed
to
be
okay?
So
how
can
like
the
next
thing
you
can
do
is
just
make
certain
working
is
this?
Is
the
movement
alkane
got
this
rectangle
here?
It's
just
like
anywhere
in
the
rectangle,
and
it
should
move
to.
A
A
You
can
like
get
it
to
go
to
a
particular
X,
Y,
Z
location
and,
like
the
air,
assist
on
awesome,
trying
to
scroll
down
by
Krasny
our
keys.
It's
misty.
Ok,
the
air
assist
enough.
That's
for
the
laser
sword,
that's
we're
not
using
it
that
has
not
healed
us.
This
computer
still
thinks
as
losing
is
using
a
laser
cutter.
Rigea.
A
Clarify
it
looks
sure
this
here
is
the
lasers.
Are
this
stinks
in
here
with
all
this
power
supply?
Here
you
can
see
laser
in
there
there's
a
laser
to
Freddie
about
laser
to
co2
and
that's
what
it
thinks
it's
controlled
just
bring
here.
This
drive
board.
You
just
took
it
out
when
we're
using
it
for
something
else.
A
A
Here
so
battery
is
the
better
connector
kind
of
lunch.
Now
you
can
see
the
lights
are
here
you
want
to
be
a
camera
around.
You
can
see
the
two
status
lights,
which
are
good
if
the
battery
is
going
dead
by
the
way
that
little
amber
one
goes
kind
of
dim.
Let's
help
to
know
if
it
was
yet
also
it
sort
of
starts
dimming
when
you
press
the
bat
move
them.
That
means
the
better.
We
go,
get
we're
gonna
def
batteries
can
be
replaced
as
soon
as
we
said,
Arduino
Lola,
oh
yeah,
that's
not!
A
A
A
B
A
A
A
A
In
its
got
three
outputs
for
the
step
boys
right,
one,
two
three
I
forget
one
of
them
tank.
Let's
have
one
of
those
outputs
is
going
to
go
straight
to
the
Zed
more
well
straight
to
one
of
the
barbers
women
from
there
zedler
and
then
so,
there's
going
to
be
another
plug
or
two
that
looks
like
this
on
the
drive
board.
Actually.
A
B
A
That
would
it's
not
know
this
feeling.
How
are
they
all
on
board
is
like
you
do
that
easily,
whereas
this
is
good,
quick
fix
the
destructive,
much
and
then
experimenting
with
other
parts
of
the
system,
because
I'm
like
just
like
getting
a
Saracen
studying,
is
learn
and
design
the
rest
of
the
system.
Instead
of
waiting
for
somebody
to
do
this
press
before
we
can
move
on,
so
it's
like
drinking
in
parallel,
so.
B
A
So,
to
use
this
machine,
you
take
an
SVG
file
or
dxf
pop.
The
except
file
is
like
easily
exported
from
solidworks,
and
I
like
a
softer.
It's
like
this
kind
of
problem
and
no
imported
into
the
go
to
the
booty.
The
toolchain
is
this
man
sits
on
pilot
park.
Then
you
got
a
button
here
on
the
screens
import
new
clicking
airport.
A
This
is
supported
platform,
Isis,
spt
and
picked
up
and
they
are
going
into
X
etfs,
except
for
directing
this
up
and
suppose
we
go
like
this
Oh
test,
rectangle
I
pqe
and
then
here
you
can
change
the
feed
rate.
This
is
important
because
give
it
the
future.
It's
too
high.
The
torches
not
be
able
type
that
fast.
So,
like
a
good
for
you
break
the
equivalent,
the
church
is
supposed
to
be
able
to
cut
a
40
inches
per
minute.
A
Suppose
that's
what
the
manufacturer
says,
but
if
I
make
it
30
in
tremont
inches
per
minute,
that
happens
to
be
about
seven
hundred
and
sixty
two
millimeters
per
minute,
because
he's
unison,
I'm
millimeters
per
minute,
and
that
leaves
a
power
that
doesn't
apply
to
us
that's
happening.
This
is
the
color
the
lines
here
you
can
make
them
different
colors
in
your
sqd
file.
This
doesn't
apply
to
ducky,
except
because
n
DX
s
are
always
the
same
feeling
pretty
sure.
A
Maybe
anyway,
and
so,
if
you
had
a
red
line
in
here,
you
have
another
button.
You'll
automatically
recognize
the
red
and
then
click
read
the
green
lines,
each
other
whites
and
that
way
you
could
have
different
beats
beats
and
if
you're,
using
these
laser
parts
for
the
different
colors
and
that's
what
you
can
t
think
happens
if
I
may
use
that
the
future,
for
whatever
reason
sure.
B
B
A
B
A
B
A
The
conversion
is
done
inside
the
JavaScript
applet,
so
like
the
SVG
and
the
except
I'll,
never
actually
the
computer
just
kind
of
cool
and
then
so
the
g-code
goes
to
hear
over
the
Wi-Fi
and
then
it
from
here
it's
like
you
can
see
a
sort
of
connection.
It's
got
all
these
pins
going
through
down
to
this
lower
board.
A
Here
it
streams,
d
commands
one
at
a
time
to
this
thing
here
this
little
computer
eet
mega
and
then
that
control
that
interpreter
g-code
so
like
a
g-code
command,
will
say,
go
to
this
particular
X
positioning
and
especially
y
position,
and
this
sends
the
relevant
number
of
pulses
to
the
summer
more
drivers.
That
can
bring
our
signal,
and
that
goes
if
the
cable
here
Stifler's.
A
A
So
what
just
happened
here
is
I,
never
noticed
it
gives
you
a
little
status
symbol.
Look,
they
float
up
here,
nice
little
bubble
and
you
can
go
to
blogs
here
to
see
a
record
of
those
little
bubbles.
Oh
now,
one
of
the
messages
that
came
up
said
timeout
laser
serve
it
down.
That
means
for
some
reason,
this
java
applet
is
not
communicating
very
well
with
the
little
beetle
and
black
and
that's
doubly
because
a
big
old
black
crashed
or
something
thanks
to
do
that
now.
A
So
for
future,
because
this
video
is
for
future
interest
rate
right
so
see
the
crashing.
A
good
thing
to
look
into
would
be
the
power
supply
because,
although
it
looks
like
a
software
issue,
sometimes
the
power
supply
is
such
that,
like
there's
a
ripple,
that's
either
too
high
or
it
drops
to
about
the
low
voltage
and
something
happens
to
the
cuter.
And
although
the
little
LEDs
are
still
on
see,
it's
still
working,
it
has
been
crashed
yeah,
but
just
because
I'm
Paris.
Why
not?
Because
the
soccer
was
crappy.
Ok,.
A
Yeah,
maybe
a
dreadful,
definite,
I,
belong
and
so
like
I
would
probably
look
into
that
who
are
blaming
the
software
on
the
people
because
it
just
started
doing
this
relatively
easily.
So
we've
your
something
to
connect
here
and
then
still
just
like
you
tell
you
what
it's
going
to
do.
Did
you
go
back
with
like
mid
more
motion?
Let's
just
do
the
home
check.
A
A
B
A
B
A
A
A
That
just
holds
it
up,
but
you
don't
want
this
to
your
channel,
because
when
this
thing's
moving
like
it
looks
up
to
you
right
now,
but
if
it's
in
the
middle
tables
a
different
situation,
you
take
care
of
us
hang
down
lower
because
they
have
more
slack
right
and
they
can
get
caught
on.
The
decimal
is
moving
I'm,
making
a
pot
on
these
things.
A
A
B
A
It's
pretty
good
right
now,
but
that's
not
a
good
solution
that
you
have
like
she'll
like
wrap
it
all
in
last,
dance
yeah
only
on
something
like
so
they're
quite
well,
spend
it
from
CH,
like
you
sure
you
to
figure
out
a
solution
up
from
the
tracks
in
the
meantime,
if
you
want
it
to
or
maybe
even
it
has
a
better
cost
for
anyone
in
the
tractatus
yeah
I,
don't
know
how
much
does
this
cost?
Oh
good,
cheap,
plastic
and.
A
A
B
A
So
the
emergency
stop
is
instead
simply
unplug
the
power
supply
to
do
shuttlers.
That's
very
clicking,
good
friends
move
so
thing
is
that
when
you
plug
back
in
again
the
signal
the
drive
board
may
still
be
sending
a
signal
to
the
second
motor.
So
when
you
hug
me
again,
I
am
I.
Stop
moving.
You
hang
out
much
my
office
yeah,
so
much
after
that.
What.
A
A
Via
and
away
in
a
jam,
there's
two
kinds
of
jams:
there's
one
where
the
stepper
motor
always
like
there
may
be
broken
action
here
or
something
or
it
may
be
there
any
mud
on
the
tracks.
In
one
case,
I
have
someone
had
loosened
little
bit
me
I,
don't
remember.
Probably
me
I've
had
loosened
these
bearings
like
the
not
here
that
loosened
and
that
was
causing
to
jam
on
the
other
side,
sie
Jonathan.
Now
the
other
thing
to
watch
it,
for
this
is
the
more
general
definition
display.
A
B
A
A
Manual
quarks,
basically,
it
has
the
hips.
Yes,
there's
no
gas
control
toys,
there's
no
other
math-ph.
There's
nothing!
There's
a
little
Lieber
here
this
video
action
months.
This
is
actually
wishing
torch.
This
is
where
they
do
it
in
the
industry,
like
they
don't
have
a
gas
control,
so
it
the
awkward.
It
turns
this
thing
on
appears
and
then,
if
I
wreck
off
again
when
they
done
pissing
like
so
like,
although
this
looks
like
a
chibi
half-assed
way
of
doing
things,
it's
actually
they
do
things.
A
Similarly,
an
industry
because
it
is
a
pretty
cost-effective
way
to
do
it
and
you
have
to
have
an
operator
than
in
any
way
the
supervisor
for
safety
and
stuff
so
like
if
they
do
one
more
thing
or
one
less
thing:
it's
fine!
It's
still
it's
it's
a
huge
huge
leap
forward
or
how
much
the
manual
machine,
because
Justin
can
do
precise,
shapes
and
stuff,
but
you
can't
do
if
you're
just
doing
so.
If
you
brought
me
in
to
watch
out
for,
is
that
D
to
just
another
step
motor
here
right
trick.
A
I
know
there's
one
over
here
is
one
over
there
and
they
don't
home
separately.
What
happens
is
the
drive
board
kept
them
during
the
whole?
My
cycle
tells
whole
thing
with
this
way
until
it
hits
one
or
the
other
of
the
limit
switches
and
then
both
of
them
stop
and
then
in
this
backwards
by
Sammy
or
something
right
and
thing
is
that
this
whole
thing
one
of
the
stairs
can
be
further
ahead
than
the
other
one,
and
so
this.
B
A
Thing
can
be
skewed
like
this
way.
It
can
be
rotated
around
the
access
to
extend
vertically
here,
which
is,
if
that's
true,
then
you
doesn't
know
that
right.
So
it's
going
to
continue
cutting
you.
Try
to
cut
some
parts.
Wins
it's
cute
like
that.
All
your
parts
are
going
to
be
like,
like
suppose,
that's
a
rectangle
skewed.
B
B
A
A
A
Up
the
exec
you're
going
to
me
checking
to
make
sure
that
the
after
homies
vessel
this
position
this
time,
because
that's
first
of
all,
I
supposed
to
get
the
settlers
in
another
position,
so
you're
gonna
have
to
manually
check
until
we
fix
this.
But
this
set
water
is
in
the
same
systems
as
you.
Please
I'm,
just
a
little
much
as
you
should
be.
