ahh.. name of the source
jepler: nice one
I see you took over the idea for printf :P
jepler: r u still here
if you were a cookie, would you want to be eaten, or saved for later?

I haven't even turned on my mill in months.
has anyone here ever used a usb jog_pad
jlmjvm, not I my friend.
No, but I used a PS/2 NUMPAD as a jog pendant.
,i use a usb num pad myself,but have a usb shuttle express here and was trying to make it work

I'm not fond of USB for the most part. Especially for critical timing I/O stuff.
these work great in mach3
i put the web site up
With the PS/@ KEYPAD, I can just daisychain if I want more than one, and no drivers are required.
even works in DOS too =)
thats what i do with my usb keypad,have a usb extension that i plug in when i need it
didnt know the ps/2 would work in dos
on the shuttle the outer ring is spring loaded and rotates 90 deg either way,the inner wheel has clicks
its for people that want a wheel,this is the second one ive gotten for my mach3 customers
wife is leaving for Cancun tomorrow morning.. the loser. ;)

you're supposed to commit stuff when I'm not home ;-)
that sounds devious
its because the compile farm brings my PC to its knees
especially when doing full builds
are they running as vm's >
3 of the 4 are VMs
I can see how that would be annoying
especially since I'm experimenting with FPGA place-and-route, which is very CPU intensive
alex_joni says I'm supposed to ask you how you like my C++. http://emergent.unpy.net/files/01172617016/fb.cc
I saw that discussion
I don't do C++
it is evil
mistrusting of objects are we?
I agree, more or less
but I had a great sense of satisfaction after writing that C++ program
while I was reading that discussion (and pondering the perversness of the people who hang out here) I thought about how I (as a hardware guy) might take that test
C would be my first choice, I know it better than any other language
but vhdl might be fun
(hard to print the results tho)
2400 baud serial 7E1?
could probably produce a 10 bit output - the number on 8, and two more bits to mark fizz and buzz
the serial output would be for extra credit
and rather insane
since the actual calculations would be finished in less than 0.01 bit times
fizz is mod 3 and buzz is mod 5, right?
something like that
couple of johnson counters would do the trick I think
no more fizzbuzz!
that article did keep me awake during calc class tonight though

quiet in here lately at this time.
I never had any luck getting the shuttle to work
sorry to hear that
cant stat device() device dev/input/js0 is what is showing
somehow it doesn't get recognized
hal : 20: pin joypad axis 0 does not exist
jlmjvm: if the device isn't recognized, no HAL pins get exported
wonder why its not recognizing
how do i open in terminal like you were saying
i found dmesg,want me to put on pastebin
[10:46:15] <jlmjvm> http://pastebin.ca/375495
jlmjvm: unplug the shuttle
then plug it again
[10:55:24] <jlmjvm> http://pastebin.ca/375501
heres the new dmesg with it plugged in
I don't see anything about the usb device
(don't start emc2.. just unplug/plug the shuttle)
did you want me to restart emc after i unplugged/plugged and pastebin
we don't care about emc now..
just unplug, plug the shuttle
what did you want me to pastebin?
and pastebin the dmesg
k,thats all i did
the USB device SHOULD appear there
the one at 375501 ?
I don't see anything about USB there..
can you try another USB port?
[11:09:47] <jlmjvm> http://pastebin.ca/375512
yes,want me to move
no, now it's ok
what hal files are you using?
[11:12:00] <jlmjvm> http://pastebin.ca/375515
I guess it's not a joystick then
i was wonder if it was showing up as something different
yes, it shows up as a HID
Human Input device
the device is working,the outer ring will scroll the page up and down
and I think it should be able to work with the new stuff jepler made
yes,hid is what it uses in windows
it's a program that creates HAL pins for any input device linux knows
but I have little clue about it :)
jepler has a program that does that?
yeah, he submitted it into emc2 TRUNK
so if you're running CVS you might be able to try it out
there is a manpage for it
i can try
ive never done a cvs yet
where can i see the device manager in ubuntu?
in the menu somewhere
* alex_joni has no clue :D
jlmjvm: can you do "less /proc/bus/input/devices" and pastebin that?
[11:24:09] <jlmjvm> http://pastebin.ca/375535
should all this be in 1 hal file,or should it be seperate and add a line to the ini file
did you unplug the shuttle?
it should be in that list
its plugged in
jlmjvm_: sorry, I don't know..
i wlll try to talk to jepler later today about his program
i dont think linux is seeing it as a hid yet
is that what you think
I have no experience whatsoever with linux & hid
all I did before simply worked.. never had to start digging :)
you have used a shuttle with linux before?
no, but other HIDs
like USB mouses
i bet this 1 will have to be built from the ground up
i wonder if i should try to load the software that came with it
i dont think linux is recognizing it as a hid,i wonder if fedora core 6 will see it?

was that what i put on pastebin earlier?
what is that?
yeah, from your dmesg
ok,guess linux is seeing it then
you might want to look around /proc/bus
and see maybe you get further intel from there
i have amd
intel = intelligence, aka information
missed that one by a mile
i just found a file that says the id of this should be 0b33,does that mean anything/
not to me :)
if a servo motor says its 640 oz in,is the the same as 40 in lb
found some servo motors that are 600 oz in,but was wondering if they were strong enough for a bridgeport
does anyone know of anyone using the mesa board to run their machine?
websites would be great
skunkworks: not by name, but there are a few
(not from the group buy though)
jlmjvm_: this line means that the device is likely to be usable by the new hal_input: [170081.829433] input: Contour Design ShuttleXpress as /class/input/input5
however, hal_input is not a part of emc 2.1
this thread from yesterday now has a mind of its own
[13:27:57] <skunkworks> http://www.cnczone.com/forums/showthread.php?t=32832
jepler: shouldn't it appear in /proc/bus/input/devices ?
alex_joni: yes, it should
did jlmjvm_ say it didn't?
I didn't read any further back
13:16 < alex_joni> jlmjvm: can you do "less /proc/bus/input/devices" and
13:18 < jlmjvm> http://pastebin.ca/375535
the other thing to do is "ls -l /dev/input" to see if an entry is created there when the device is plugged in (that's what hal_input actually uses)
but linux has to recognize the device before hal_input will use it
sorry was away for a minute
jlmjvm_: looks like you have to resovle why the kernel doesn't recognize the shuttlexpress as an input device before there's even a question of how to use it with emc.
jlmjvm_: nobody here is an expert in that area
so the kernel isnt seeing the device
it sees it as a usb device, but not as an input device. There are probably several layers in the kernel between those two. At one of those layers, the right thing is not happening. But like I said, I am not an expert.
so this could possibly be added between the layers by somebody that knows kernels/
cool,i know where a couple of red hat developers work,may have to stop by for a visit
it need to 2.6.15 magma,right?
het wait a min,when i sent you the file a min ago i didnt have it plugged in
the short answer is "yes", because if you change kernel version you have to add the realtime patch to the new kernel and recompile emc2 -- not a lot of fun
jepler: new file http://pastebin.ca/375646
that is more promising. You'll notice that there is a new "event3" device in that list, compared to the earlier one.
i see it
do you want me to do "less /proc/bus/input/devices"

* cradek grumbles
you mean the ask & run?
yeah, I think it's stupid
it might be that people don't know how IRC works
or they think that if it's silent there's no-one here
i know im new to irc
and linux also
jlmjvm_: nothing wrong with that
gotta step up to the plate sometime
im very pleased with the new version yall have made
it had a bugfix that you needed?
when my new gecko gets in today im gonna cut something on my bridgeport
is it an old stepper bridgeport?
how do you get to your tool offsets and fixture offsets using the axis gui
yes it is
you kept the original steppers with the big fins, but run them with geckos?
how does that work out?
they are strong motors,but cant get em past 140 ipm
140 isn't bad at all for old steppers
but for 100 ipm rapids they work good
what supply voltage do you use?
about 65v dc
interesting, thanks, I've always wondered how one of those would run with just new drivers
for tool offsets, you just edit the tool table (something.tbl)
for a work offset, use the "touch off" button in AXIS
they run great if the motor isnt wore out
I bet they run a lot cooler with chopper drives
they dont get all that hot
in your config directory, you'll see a .tbl file
yes,mine is stepper.tbl
that's where you put your tool offsets for diameter and length
do you mean change the offsets in the .tbl file?
jlmjvm_: then you use M6Txx (xx=tool number) to change to the appropriate tool
now i see
jlmjvm_: the default file only has 4? examples
told ya i was new,lol
you will want to write all your tools there...
M6T1 will cause the machine to change to tool #1
(depending on the configuration that toolchange happens automatically, or needs to happen manually)
configuration, capabilities, etc
can you have this file open while emc is running
it is now
in AXIS there's a "reload tool table" on the machine menu
you have a button/menu entry somewhere in AXIS to reload tool table
what cradek said
what alex said
jlmjvm_: know how to handle recursion?
k,i saw that was fixing to ask about that
yeah, a programming technique
programmer humor, never mind alex
over my head
jlmjvm_: probably too ahrd to explain anyways.. (the main idea was that if you look what I said was to look at what chris said, and he said to look at what I said, etc...)
that's a recurrent thing (like a loop)
now i see what your talking about,had missed that,was flipping between workspaces
as yall were saying that i was thinking how do you enter an offset once running after you change the .tbl file
you use touch-off for that (if I understand what you're asking)
I don't think I understand the question - can you give more detail
what i meant was if you run a tool,and measure work,and make an adjustment in the .tbl file,would it be active,and it should if you hit reload table
are you talking about coordinate system (work) offset, tool radius compensation, or tool length compensation?
tool length and radius compensation
you enable tool length compensation with G43, and you enable tool radius comp with G41/G42 and appropriate entry moves
that's after you load the tool data from the tool table
i fully understand that,been a cnc programmer for 24 years
if you change the tool table, you do have to tell EMC to reload it
what i meant was the tool offsets,say you make a cut and want it .005 deeper
do you adjust the tool offset,and reload table
yes you could do that by changing the tool length offset
wont you have to reload table
or you could jog/MDI to Z0 and use "touch off" entering 0.005
yes you have to reload the tool table after changing it
do you have tool holders?
would mainly be doing that when sizing in cutter comp
yes,have 8 holders
good, you can stick the tools in them and just measure them once then
yeah I've tweaked the tool radius to get a part to size like that
length isn't so fiddly usually
its what you have to do on any mill
naw if you do a good setup the lengths are usually there
usually gotta adjust the comp though

hm -- if you can print and read the "samples" at 300/inch, you need to scan across 26.7 inches/second just to get 8000 samples/second
jepler; some type of mechanical fft?
or low-tech electronic components?
lerneaen_hydra: I think you just amplify the response of the photo sensor and play it on speakers
oh, I see
take the sound, resample to 8000/second. Print the "most negative" sample as 100% black, the "most positive" sample as 100% white, and the "zero" sample as 50% black / 50% white
oh, so similar to the system used on video film with audio? (varying width clear track)
put it on a cylinder and do a helical scan at 26.7 inches per second
but I don't think you'll get much sound on a piece of letter or A4 paper
what about rastered dots (digital) with some error correction? how many MB would you think that would be? 20mb B/W and 60 for color?
that's about 3 revolutions per second .. to get 100 different sound levels represented you need 1/3 inch, so that's 1 inch "down" the drum per second .. so only 11 seconds of audio per letter paper
if you do 600DPI it gets 4x better but you still don't have even 1 minute of AM-quality sound per sheet of paper
lerneaen_hydra: to read a digital code you'd need a much more complicated sensing system
wouldn't a digitalisation give quite a bit of space?
jepler: saw some nice 2400dpi printers lately
yeah, but with todays systems
for this all you need is a single sensor looking through a small slit, and it's all analog
* skunkworks hates analog
jepler: right, but using digital you could read a couple tracks at once
* alex_joni thinks of interleaved spiral
OK, I take it back, this would be a terrible DIY project
I bet it never worked in the first place :-P
we probably have higher expectations
phonographs didn't sound like DVDs.. did they :)
1khz freqency responce is ok for voice ;)
ah -- I have a better idea
maybe so.. but 8kHz is crappy for music
hmm, if digitalised on paper and with .5mm squares you only get 30kb
but it's a pita to read that back reliably
is that dots per linear inch or inch^2?
I think those 2D barcodes (datamatrix & co) are as good as it gets
lerneaen_hydra: linear inch
say that you can read it at 1200dpi reliably then
you'd have 2400x2400 per square inch
1200 dpi -> 0.02mm dots
yup.. a PITA to read reliably
so 2500 dots per mm^2
get one of those old "high speed paper tape readers" (this one says 300 8-bit characters per second), and a microcontroller/fpga implementation of an ultra-low-bitrate voice codec to do audio from paper tape
[20:12:53] <jepler> http://www.pdp8.net/pc04/pc04.shtml
why not punch cards?
if you can read at 1200dpi you get 18.5mb per page
then to listen to a song, one would have to change 2.75 punchcards/second
alex_joni: that would be just crazy
lerneaen_hydra: no way you can do that reliably
datamatrix is .5mm I think
.1 shouldn't be too hard to do
lerneaen_hydra: to read it's hard
not with a modern scanner
0.1 only gives you 760kb though
use a 500 page block
oh, and duplex printing :D
I like the tesa-stuff better
that's a better idea
760mb for something around 100 times the volume of a CD
they researched encoding data on tesa film
using CD technology
lerneaen_hydra: scotch tape
laser in the middle, rotating
lerneaen_hydra: no, regular sticky tape
with or without the adhesive?
you have lots and lots of meters on one small roll
standard scotch tape?
lerneaen_hydra: yeah, standard
how'd they encode the data?
they used a laser and focal control to focus on each layer
small burn and it would bump
and that can be read back
4-5GB / scotch tape roll
the tape physically deforms?
from the heat?
lerneaen_hydra: it creates a bubble (blister)
yeah, from heat
they must be very, very small to get 4-5gb
I think a roll of tesa is about 30-40m x 19mm wide
found an online article (in german)
it seems there are about 30 um between sheets
easily doable with laser
what about the blister's size?
they say it doesn't affect the neighboring layers
max. theoretical data size is 10GB
but they aim for 3-4
sounds about right

google for tesa-ROM
(tesa is a german manufacturer like scotch)
the bad news is that they showed it on CeBit (a large german fare)
but that was in 1999.. not much happened since
lerneaen_hydra: found a note about "Recent progress in electron beam mastering for 100Gb/in^2 and beyond"
* alex_joni talks too much

Does EMC2 support USB?
what do you mean by usb?
a usb paralell port?
ogarr: no, emc2 does not support controlling motors through a USB port
03jepler 07TRUNK * 10emc2/src/hal/components/lut5.comp: lut5 didn't work right for functions higher than 0xff
I figured it was smooth sailing after I saw that functions 0, 1, and 6 all worked .. but I was wrong
I've cut stuff with the plasma/oxyfuel machine today
the only issue is that I need another drive belt on the X axis..
to make it stiffer..
so.. is that emc?
bought sheetcam to do the nesting..
how good is it nowadays?
I used sheetcam when it was beta/free
not _extremely_ but it's easy to use and wseems to work really well..
I'd want it to do automatic nesting..
that's the only bad thing
anonimasu: for <1k$ ?
sheetcam is like 140eur..
yeah, I know
auto nesting is 4k+
alex_joni: yeah, I'd love it to handle that..
I dont get it why it's so expensive..
anonimasu: because people are willing to pay that
this is great: http://blog.modernmechanix.com/2007/01/22/batteries-of-robots-scoop-power-from-sea-with-shovels/
alex_joni: well, as long as it gives me toolpaths for little work :)
I need 40 parts of one kind 20 of another 30 of a third... and 10 of something..
a sheet of each kind of thickness approximately
anonimasu: there are SW out there that can easily handle that
along with keeping track what you have in your storage
it's not worth the hassle..
including scraps from older cuts
or the cash for it..
this is one full run.. of parts..
so you just tell it what you want to cut.. and it'll tell you what to use :D
plasma is overrated for thick stuff.. :/
anonimasu: how thick?
too small machine ofcourse..
I just had a request for 60mm the other day
it cuts but not at sane feeds..
guess how much such a machine is :P
err 40k eur..
300A, 300V :P
that sucks really..
well.. if you need it :)
yeah, but I'm comparing to the oxyfuel torch we are running that cuts 30mm like butter..
with no noticeable kerf..
oxy is nice for thick stuff
seen 3500mm cut once
guess 30mm is nothing compared to that
we've got a torch for extremely thick stuff somewhere..
runs on LPG instead of acetylene
for extremely thick stuff, you use a 'lance' (I think it's called)
still, oxyfuel seems to work damn well, compared to the price..
looks like a meter long stick
yeah, can't beat the price..
but some need the quality or speed
especially under 30mm
but thoose people probably arent cheaping out building machines themselves either :)
I reckon so..
seen people cutting with a laser up to 20mm
that's a LOT of power
did you hear the quote we got for a machine?
or was it 3x2..
2x1 is tiny
or plasma(without powersupply and stuff)
without a cnc control..
that price would be ok for a CNC 3x2m
did google change it's format from yesterday to today?
alex_joni: nothing's as nice as to watch your machine make parts :)
alex_joni: though im a bit too busy to really enjoy it
a-l-p-h-a: looks about the same to me
anonimasu: I know how that goes
now the only issue is getting height sensing..
and automating ignition cut/idle flame :)
[21:31:04] <anonimasu> http://en.wikipedia.org/wiki/Thermic_lance
anonimasu: for plasma?
alex_joni: no oxyfuel..
alex_joni: though I'm not sure if we really need it..
alex_joni: it dosent seem to be as sensitive as people say
what's your deviation?
for those 'small' plates it shouldn't be too much
but a 12mx3m sheet might have some bends in it
well, I cut 2mm from the plate now..
im pondering about ultrasonic for the height sensing..
plasma is nicer.. with voltage control :)
anonimasu: I saw some article once for oxyfule that used a webcam to analyze the flame size
alex_joni: it's too bad the plasma wouldnt cut thick stuff easily..
a big one would
but it's too much $$
bah, so would a laser..
or a waterjet
a 50mm machine costs double than a 40mm one
I have a small handcarried unit that does 45mm
but it struggles
iirc, pier was inq about hotwire cnc w/ emc, but sounded like emc couldn't do it. Is this true?
depends on what you mean..
alex_joni small handed carried unit that does 45mm... Don't most folks call that a gun?
don't remember what pier wanted
Jymmmm: for plasma cutting
Pier wanted to use emc to do hot wire foam cutting with tapered cuts. 4 motors
XY above, XY below?
side by side
just a sec, will grab pics
something like this... http://www.foamlinx.com/fc2913.html
what would he use to describe the motion? gcode? G1 X Y x y ??? not in the interpreter (or kins)
[21:44:53] <Jymmmm> http://www.deskcnc.com/Airfoil_Tutorial.html
He said that he wrote it manually (not sure exactly what that means though)
I think xyuv is normal for foam cutting wire
(uv would be ab in emc)
cradek: including a tapered cut?
yes to do a taper, u,v != 0
cradek sorry, just learning here, no clue what that means.
I just have all the parts to make a foam cutter, thought I would.
Jymmmm: the motors on one side are (X,Y) and on the other side (X+U, Y+V)
Jymmmm: so U,V determine the "slant" of the wire
So, this is something that's fairly striaght forward?
yeah, i know the forms, i work with airfoils a lot, turbine blades... if he can get what he wants to motion, then emc/hal can do it, it wont be normal gcode for 2 different curves top & bottom, or for when one pair needs to preceed the other ( lean into the direction of the curve ), he looses some of emc that way but can get what he needs
wow that doesn't look like $3000 worth of stuff
cradek: It's an "out the door, ready to go" package.
yeah that's worth something I guess
"High Torque - 110oZ*Inch"
it only has to move a wire...
Big time, you are putting the tequilia/asprin money into the machien w/o the headaches/hangovers =)
Cutting speed: 16"/min
jepler you dont want to cut foam too fast/slow
they have videos on that page
[21:52:06] <Jymmmm> http://www.foamlinx.com/FAQ.html
At the moment Foamlinx machines do not support automatic heat
I would expect that for 3k$
I just streched a piece of mig wire between the headstock and tail stock of our lathe and used 2 patterns on each end of the foam to make the airfoil ;)
did you heat it up?
Eeeeesh... grow the beans, harvest the beans, roast the beans, grind the beans, brew the beans....
so on this kind of machine, the wire length is maintained simply by a spring? how well can that possibly work?
alex_joni: Yeah, I thought that maybe I could use spindle control within emc for heat control.
alex_joni: I had a 30amp variable power supply iirc
jepler hotwire stretch when heated, the spring is just to maintain tension.
jepler: That is what I did to keep tension on the wire - spring on one end.
I bet if you're cutting the right speed, the foam barely touches the wire
cradek and if you're going to slow you get this BIG hole too =)
yeah I bet
I was thinking of the length change of the wire as you do moves in UV
sounds like a jog for temp-meter and adaptive FO
jepler I'd think a longer spring would compensate for that (within limits of course)
about the 5th picture can be enlarged to show how the motion gets tricky with airfoils ( velocity of xy not same as x'y', entry angle not normal to surface... ) http://www.peps.com/products/wire.htm#
jepler Personally, I was thinking about using a idler wheel on a spring loaded slide.
tomp which link?

Does EMC2 support a serial connection to the motors?
ogarr: I haven't seen motors with serial interface
except CAN or Profibus maybe
ogarr: where you able to boot into ubuntu?
I'm trying to figure out how to connect to a PDF or a maybe a Crystalfont unit
Yes, I got ubutu up and running
ogarr: it depends what they expect on the serial line
ogarr: the "HAL User Manual", chapter 6, details the hardware interfaces supported by emc2. http://linuxcnc.org/docs/2.1/HAL_User_Manual.pdf
as it is now, emc2 doesn't work with serial devices.. but depending on what you need it can be hard or easy
Thanks, I just downloaded the manual.
emc2 lets you write drivers for new hardware, but it requires considerable knowledge and the ability to write code in C.
Which is WAY beyond me.
* alex_joni requires considerable sleep
good night all
ogarr: or... If you donate hardware to the developers - they will most likely write a driver for you. If you ask them really nice also.
How many ways can I say please? LOL
ogarr cash, check, charge, first born, etc =)
I have to check with my partner. We need to decide on a route to take before we go into production.
choosing an existing, working hardware interface is probably the best idea
(working with emc2, that is)
Jymmmm: nice vid
tomp: Yeah, no doubt.... no cad/cam either.... all programed from the pendant. eeeeeessh
check out the pics at the bottom.... eeeeesh http://www.hotwiredirect.com/products/cnc-foam-cutting-machines/
Any idea what kind of a price on those machines, Jymmmm?
ogarr no idea, at least one comma =)
a buddy needed that wedm lathe idea, but had xyuv machine. so he sacrificed the y for a rotary ( just pulled the motor out and connected to table top mounted rotary with a live ctr opposite ) and was able to 'turn' work, he just had to lie a lot to the control ( Ed Vilchez, near 1980 ) limited but did what he needed
Jymmmm: i'd be very interested how your friend pumps the data into emc ( how he requests position without using gcode ).
tomp: It's Pier in here. So catch him when he's here, or send him a memo
(if he's registered that is)
Jymmm: Pier: http://imagebin.org/7424
Ok, just got off the phone... the 8700 goes for $40K USD, runs on servos, can do 6 wires at a time, comes with BobCad, and three days of onsite setup and training.
Ya know, that's really not that expensive when you think about it.
the onsite stuff is included in the price, I know lots of places that charge extra for that.
tomp what are those pics of (specifically)?
