where is my rt dir ?
checking for RT dir... configure: error: RT not found. Specify:
if it's in the standard location it will be detected
otherwise, it's where you put it
im not using ubuntu
with RT kernel
then the second part of my answer applies...
where did you install rtai?
checking for Linux source tree... invalid
configure: error: /usr/src/linux is not configured -- --with-linux-dir sets linux-dir
dang, time to rpm hunt
how did you build rtai without kernel source?
Ive never seen so much bullshit played off as intelligence I had in skipping though that video
they just used the facts
its a great movie
not for the weak minded and poor though
guess that means you did all the research
dont hear me wrong.. I can buy into alot of that... but some of it is grasping at straws
you know what i've noticed about straws
is that they're always around
until you really need one
user__ is now known as SkinnypuppY34
i am looking for more information about the EMCTask and his internal architecture. Can you help me ?
* ZaaN wait on answer
is this channel alive ?

isnt your boss still a factory machine,no control changes yet?
or do you have emc on it
it's still nearly factory
ZaaN: the source code is the primary reference. there are other notes in http://linuxcnc.org/docs/2.2/html/code_Code_Notes.html
but they are not rigorously kept up-to-date.
i had forgotten that they program differently from a modern g code machine
yeah everything is a little different.
jepler:python is the language that you need to know to make changes or add to usr/bin/axis,correct?
jlmjvm: the file /usr/bin/axis is written in python
axis relies on other code written in C++ and tcl
im gonna try to find someone local to help me with the tool offset touchoff button,what do they need to know,C++ and tcl?
I guess I don't know enough about what you want touch off to do to be sure
if it is changing something about how the GUI displays items, then you would need python and tcl knowledge
if it's changing something about how EMC works, then you would need C and C++ knowledge as well
all it needs to do is put the value in the tool.tbl
writing files can be done in python, and you can look at existing code in axis to see how to request that emc re-read the tool table.
then a regular cam system can output a correct program
tcl knowledge is often also needed when you modify the appearance of an axis window or dialog
i can make it put the value in the var file,but not the tool.tbl yet
is tcl a common linux language that a local linux guy should know,or is it emc specific?
tcl is a very old language
it is not an emc creation
if the only part left in your problem is "read tool.tbl; modify one line; write it again" then the task can be done all in python
that appears to be all thats needed
then instead or using a var# it would use the tool.tbl,a regular cam system would output the correct code,and the tool diameters would show up in the gui when running
i really dont remember any machine tool control that i have used over the last 24 years that didnt have a tool touch off
dont misunderstand me,i think axis is the hottest machine tool gui ive ever seen,when i saw the first screen shot of it last year i made up my mind to learn this package
but 1 very important and basic function is missing
that's the principle of open source: you don't have to depend on one individual or company to add every required feature.
if you complete this feature, I'd be grateful if you sent the changes to me so that it can be in a future release of emc
if i knew more about python we would already have it
will be more than glad to
i dont wanna violate any ethics of the room but im looking for someone to contract this to
its that important to me
remember this guy? http://www.stensat.org/projects/halloween_2007/inv_tripod/inv_tripod.htm
that's not an ethical violation or a violation of the gpl.
the problems come when you say, or that person says: I will give or sell you the binary program, but not the source code you need to make further improvements
naw,it will have to released to all
in general terms, yes.
I'd have to see the actual source code changes before I'd say "yes, this code is suitable for adding to emc"
obviously you would be the perfect candidate
gotta run,think it over,im for real about this
there are a video on the sit also - I am thinking lawn mower... ;)
boy - lets try that again
there is a video on the site also.
skunkworks685: that's the greatest thing so far this month
absolutely crazy stuff, love it :D
I think this should also be linked from the wiki. (should I ask?)
skunkworks685: mayeb added instead of linked
yeah, sure.. go ahead
[14:15:01] <skunkworks685> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Case_Studies
I will nudge him and see if he will add a page on the wiki.
[14:18:16] <skunkworks685> http://www.cnczone.com/forums/showthread.php?p=369265#post369265
there is an nml message, maybe currently disabled or broken, that will change/write a tool table entry. That should be revived to do tool touchoff correctly.
I would also like to see that in emc somehow
I think to do it, you'd have to use negative tool offsets (or something - I haven't thought it through)
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-11-21.txt
a complete solution would also have to include lathe tool entries (orientation, X and Z offset)
at least x/z
(for touch off)
but yeah editing them all in the gui would be best
why do we want such special cases for TLO ?
on a PUMA robot you have a XYZ tool offset
relative to the latest joint
and some ABC tool orientation
alex_joni: probably only because we're facing a tool table with 10+ numbers per tool, almost all of them being zero
I'd also like it to be more general
at least xyzuvw
even a knee mill would be able to use W tool offsets
a frien of mine reported to me a bug, but I had no time to test it yet, it is in the 2.2.1 version (but was the same in the previous versions)
when you load a g code, axis can calculate the working time
but this is always wrong, at least in the mm version (I don't know if it is worng also in the inch version)
it is always about 400 times less than the real working time
25.4^2 = 645
do you know the way it is calculated?
in sim/axis_mm it looks pretty reasonable (38 seconds for the AXIS splash screen)
ok, now I will try on my computer...
although it actually took 55 seconds to run
strange. the same file in sim/axis (inch) says 45 seconds
oh of course, the speeds are different
there is something strange...
I would like to try with something simple
the time estimate does not correctly account for inverse time feed moves or spindle-synchronized moves -- it will probably give wildly wrong answers there
it does not account for ABC or UVW movements
it does not account for acceleration
it uses a very simple and wrong guess for top speed available: the maximum jog slider value
let's try something really simple
I think that mostly explains the difference between sim/axis and sim/axis_mm: the jog slider goes up to 3200mm/min, vs 72in/min
they both take about 55 seconds to run so the machine settings must be similar
[15:21:20] <xemet> http://www.pastebin.ca/792581
this will make a sqaure
I've set the side to 100
and the feedrate to 100 mm/min
so the working time should be about 4 min
your file does not contain G20 or G21
so whay axis tell me working time is 9 secs
is it necessary to specify G20 or G21
the machine is set in mm, so it take all measures in mm
but now I try to set G21 and see if something changes
it doesn't help when I try it
it shows 9 secs
when I try 1" square with g20, I get 4 seconds when it should be 4 minutes
ok, so there is something strange...
yes and it's not just mm
the working distance is correct
so it is in the feedrate that something goes wrong
do you know the way it is calculated?
simply Time = Space/feedrate ?
or something more complex?
are you there?
yes xemet, we are here :)
jepler and cradek are working on it
I found something that made the time calculation ignore the given feed rate and use a predefined value that didn't mean anything
it looks like there is an additional problem for metric programs, the feed rate is still taken as inches per minute
ok, so you found that there is a problem, that's a good thing, it is not a problem of my system :), I hope you can solve it in the next release
yes, I hope so too

JymmmEMC: how is it going?
ready for turkey day?
Yep, the bird is in it's hot tub, getting ready for it's salt bath!
you always talk about your birds and I wondered what you were doing to them now
they are cannibals
oh - I don't know if I could do that anymore. I am sure the wife wouldn't be able to handle it.
Don't name the turkeys..
but I forgot, some birds are pets, some are food
Actually, my gf is pretty touchy about that, or any animal for that matter.
Though I will admit, if I had to make my own hamburger, I might turn vegan.
I picked up some peanut sauce - have not used it for anything yet though.
skunkworks: on rice, over veggies, or as a dipping sauce for deep fried tofu
yum, fried tofu
no kinds of tofu are pets, so it's safe
skunkworks we buy the commercial peanut suace mix
We got it from the local food coop
know the brand?
No - not at the moment
Taste of Thai ?
my peanut sauce for veggies or noodles: equal parts soy sauce, sugar, lemon juice. add a glob of peanut butter.
cradek: no coconut milk?
mmm coconut milk
sure what the heck
Ok, we buy the tub (3rd item down)... but same as 2nd item... http://www.andreprost.com/thai_peanut_items.htm
also GREAT on chicken satay
It's WELL worth it!
lasts us a year
then we just buy cans of coconut milk and can make it as dtring ot light as we want
what - you don't milk the coconuts?
you can find it locally in restraunt supply house
skunkworks you first ;)
sometimes I get the little cans of curry paste to mix with a can of coconut milk - very easy and good
[20:44:41] <cradek> http://www.templeofthai.com/food/curry_paste/red-2110031108.php
you put the lime in the coconut and you......
(check these things carefully for stealth fish if you're vegetarian)
You put the lime in the Coke you nut, and drink them both together...
heh - I was winging it..
skunkworks no, you were correct for the original song, mine was from the "Coca-Cola with Lime" commercial
ah - ok
It was funny - we where driving down to see the singer - 'feist'. We where listening to her cd's and actually reading the lyrics. Needless to say - it changed the meaning of a few of the songs..
"I'm glad I'm a man and so is Lola"?
[20:53:23] <JymmmEMC> http://www.centralcomputers.com/corp/pages/ASUSeeePC.html
cradek: you mean, lola is also glad that you are a man?
you should be precise in your use of langauge; to do otherwise invites misinterpretation.
You guys are at least familure with "dating sites" when they ask what you're looking for? Like "I am a man, looking for a woman"?
usually abbr: M4W ???
JymmmEMC: interesting except for 800x480
Well... they do! M4W, W4M, M4M, W4W... with me?
480 is not very many rows of pixels
No, but it might be nice for grandma
JymmmEMC: OK, I believe you
Ok, now toss in the whole TS/TV/TG crowd....

stupid question - I thought the puma sim and others where in the 2.2.1 live cd
skunkworks439: yes, should be (though one of puma or scara was still broken in 2.2.1)
I thought I downloaded the latest live cd yesterday.. it has 2.1.6 on it
ok - I am sure I did. It is the only iso in the desktop.
huh that's strange

looks like it's uploaded but with a different file name
the one I downloaded from the link on the left of linuxcnc.org was emc2-ubuntu6.06-desktop-i386.iso
I wonder how many others have had the same experience :(
I've asked alex_joni to look into it
for now you can download from the same URL with .2.1 added
ok - thanks
That is downloading.
200KB/s isn't bad\
takes about an hour to download.
The link on this page is correct. http://www.linuxcnc.org/content/view/21/4/lang,en/
The link in the middle of the page under installing EMC2 looks ok, but under the left hand news column it is the wrong link
even better... "EU mirror" in news section seems to get one to the right version
LawrenceG: how is the current drive going?
current as in Amperes
current project is putting a stepper system together with some parker oem750 drives... "current drive is still in progress" The shop is getting quite cold... I am going to have to get a heater!
I am aiming for something with 0-12amp output for 12-24 volt servos but the logic part can be used with different power drivers... I also have a 90vdc motor I would like to try driving as a servo... line powered stuff lets the smoke out a little faster!
3 legged fet fuses
any interesting projects on your end?
new front and back doors on the house - footing for the garage start friday.. So no.
I have stalled on the cnc side for the last few monts
I am re-automating my shoptask to take advantage of the lathe spindle encoder I added... real parallel port chargepump type watch dog, coolant and spindle control from the computer and a few other goodies that will make using the lathe/mill a little nicer
I also have a rotary table which would benefit from adding a stepper drive... would like to make some wooden/plastic/metal clocks
sounds like a plan.
did you see this from earlier?
[22:23:34] <skunkworks439> http://www.stensat.org/projects/halloween_2007/inv_tripod/inv_tripod.htm
yes... very cool.... the idea of taking out young hooligans with a computer controller flying wrench has a certain appeal :}
some servo powered air motors would be great for some fast rapids... maybe a new use for some cheap die grinders with bang bang controls
humbug... stock market is not doing well this week
dont' watch it.. ;)
SWPadnos:which pci express video card did you say worked with emc,was it the nvidia 7300?
anyone know what this statement means? "The BOSS 6 machine has Haas rotary table as a 4th axis. I use M51 to turn control over to the Haas, then the Haas signals the BPT when it's done."
I take it that means that Haas is running a program and the BP doesn't do anything?
