[00:01:21] <eric_U> the ducks probably appreciate the coffee
[00:01:34] <fenn> and peanuts
[00:02:05] <BigJohnT> I don't know I don't duck hunt just pheasant
[00:02:35] <BigJohnT> I call it a duck hole
[00:02:41] <eric_U> this duck pit is for someone else?
[00:02:53] <BigJohnT> a place where you duck down in while you ambush the ducks
[00:03:02] <BigJohnT> my business partner
[00:03:35] <fenn> looks like a baseball dugout yes?
[00:03:43] <eric_U> where you live, isn't that spelled bidness partner?
[00:03:55] <BigJohnT> LOL
[00:04:04] <lerman_> lerman_ is now known as lerman
[00:04:20] <BigJohnT> well it's 4' x 16' and gets buried in the mud
[00:04:40] <eric_U> how tall?
[00:04:48] <BigJohnT> and has some flip out things to hold the grass and stuff that they hide behind
[00:04:49] <BigJohnT> about 4'
[00:05:07] <eric_U> so it's 4x4x16?
[00:05:46] <BigJohnT> yep fills up my trailer for sure
[00:06:01] <BigJohnT> pluss it has two dog boxes on it
[00:06:05] <eric_U> sounds claustrophobia inducing
[00:06:18] <BigJohnT> the green one from here http://www.osceolamachine.com/?gclid=CL3r45qZz5ICFRMOIgodeCxVCg
[00:06:43] <BigJohnT> http://www.osceolamachine.com/duck_pits.html
[00:07:18] <BigJohnT> wow he paid $1500 for that
[00:07:41] <BigJohnT> they are about one hour away from here
[00:08:15] <fenn> what keeps it from flooding every year?
[00:08:25] <BigJohnT> * BigJohnT hears the dinner bell
[00:08:30] <BigJohnT> nothing they pump it out
[00:08:34] <BigJohnT> and cover it
[00:08:44] <BigJohnT> bbl
[00:09:02] <eric_U> specially formulated duck pit paint
[00:09:45] <eric_U> We also fabricate customer designed pits to suit the needs of the individual, i.e. if you are claustrophobic
[00:49:10] <Sweeper> man, ntohing like sanding cedar to put a nasty taste in your mouth D:
[00:52:19] <dmess> i love the smell of cedar in the morning
[01:21:03] <Sweeper> ok, hardware question...inkjet printers use DC motors + circuitry to drive the print head, as far as I know, and get really good resolution...what is this magical circuitry, and could it be easily DIY'd?
[01:22:26] <Sweeper> I really dunno how to frame that into googlable syntax :v
[01:23:11] <toastydeath> "inkjet printer drive thingy"
[01:26:41] <jepler> in 2003 a patent was issued for what appears to be the use of a slightly modified quadrature encoder for print head positioning. http://www.patentstorm.us/patents/6582049-claims.html yay patents
[01:27:34] <toastydeath> 300 dpi is .003"?
[01:27:38] <toastydeath> WHAT IS SO HARD ABOUT THAT
[01:27:43] <toastydeath> especially over 11"
[01:28:34] <jepler> printer optical encoder strip turns up lots more items
[01:29:13] <Sweeper> http://www.electronicspecifier.com/public/primages/pr1504.jpg <-- aha!
[01:29:18] <Sweeper> I was wondering what that thing was
[01:29:18] <jepler> toastydeath: inkjet printers that make claims of 4800DPI resolution are not uncommon
[01:29:32] <Sweeper> http://www.flickr.com/photos/sweeperpix/2400672374/
[01:29:37] <toastydeath> that would be impressive
[01:30:08] <jepler> toastydeath: no, I don't think that epson breaks a sweat claiming it :-P
[01:30:24] <toastydeath> well i meant if it really had that kind of step accuracy
[01:30:35] <jepler> this one has " * 5760 x 1440 optimized dpi
[01:30:35] <jepler> "
[01:30:57] <toastydeath> i'm pretty sure it's the printhead that makes it the ridiculous dpis
[01:30:59] <toastydeath> not the linear drive
[01:31:05] <toastydeath> not sure tho
[01:31:06] <jepler> I'm not sure which direction the 1440 is
[01:31:57] <jepler> but it's probably OK if the accuracy of positioning is low, maybe as low as 1/100 inch
[01:32:07] <Sweeper> eh?
[01:32:15] <Sweeper> then how does the printhead know where to print?
[01:32:35] <toastydeath> guessing
[01:32:50] <toastydeath> i think it's got that microscopic mesh of nozzles
[01:32:55] <jepler> yeah it doesn't really matter where each individual droplet goes when you're printing a photo on an inkjet
[01:33:10] <toastydeath> so you get 4800 dpi but the dots aren't like, a perfect grid
[01:33:18] <jepler> right, that's exactly what I'm saying
[01:33:31] <toastydeath> OR IS IT
[01:33:32] <Sweeper> that would look awful :/
[01:33:35] <toastydeath> * toastydeath dramatic music
[01:33:40] <Sweeper> you can SEE 100th of an inch
[01:33:46] <jepler> have you ever looked at an inkjet print? they always look terrible
[01:34:00] <Sweeper> well yea, text is pretty crappy
[01:34:16] <Sweeper> hmm
[01:34:30] <Sweeper> you know what would ROCK? getting a laser printer to print direct to pcb
[01:34:57] <toastydeath> in soviet russia, pcb prints YOU
[01:35:22] <jepler> I've seen a page which has an inkjet displaying the resist on a copper clad board, but it'd be a bigger trick to get the pcb through a laser's rollers
[01:35:32] <jepler> er, "displaying" is not the word I meant
[01:35:39] <Sweeper> yea, I've seen the inkjet stuff
[01:35:47] <Sweeper> but there's only the two rollers, right?
[01:35:47] <jepler> maybe I meant "spraying"
[01:36:13] <Sweeper> actually, come to think about it, it WOULD be a pita
[01:36:35] <Sweeper> the heating elements on those things come in removable cartriges :/
[01:37:16] <Sweeper> of course...there's always flexible pcbs :D
[01:37:41] <Sweeper> or maybe even copper sheeting you could glue down...
[01:37:58] <Sweeper> print, glue to plastic, etch
[01:44:10] <jmkasunich> I think the ridiculous DPIs are in the direction of printhead travel
[01:45:01] <jmkasunich> clock frequency in Hz (actually, maximim dot squirting frequency), divided by print speed in inches per second, equals dots per inch
[01:46:58] <Sweeper> so those optical encoders must be pretty sweet
[01:47:04] <Sweeper> I can't find the strip tho :(
[01:47:22] <jmkasunich> you are looking at an actual printer?
[01:47:45] <Sweeper> http://www.flickr.com/photos/sweeperpix/2400671380/ <-- loooking at the remains
[01:47:59] <Sweeper> I should have paid more attention when I took it apart
[01:48:00] <jmkasunich> I'm not sure all brands use the same approach, but the ones I've seen are a strip of clear mylar or something like that, maybe 1/4" wide, running the width of the printer
[01:48:11] <Sweeper> but I've got MOST of the parts
[01:48:14] <Sweeper> clear, eh?
[01:48:16] <Sweeper> * Sweeper looks
[01:48:26] <jmkasunich> clear except for the very fine black lines ;-)
[01:48:39] <jmkasunich> where is the printhead?
[01:48:46] <jmkasunich> the strip usually passes thru the head
[01:49:00] <jmkasunich> one end is anchored to the printer frame, the other end is pulled tight by a spring
[01:49:49] <Sweeper> yea, don't see it
[01:49:56] <jmkasunich> what brand was the printer?
[01:50:04] <jmkasunich> (the ones I've taken apart have been HP, IIRC)
[01:50:11] <Sweeper> canon
[01:50:17] <jmkasunich> others may use a rotary encoder, or some other idea
[01:50:22] <Sweeper> most of the frame is in the garbage
[01:50:26] <Sweeper> this one uses optical
[01:50:37] <Sweeper> http://www.flickr.com/photos/sweeperpix/2400672374/in/photostream/ <--
[01:50:45] <jmkasunich> how do you know, if you can't find the optical strip?
[01:51:08] <Sweeper> it's got an optical encoder on it :P
[01:51:25] <jmkasunich> that board is part of the printhead assembly, and moves back and forth?
[01:51:31] <Sweeper> yep
[01:51:45] <jmkasunich> so, what was in the slot?
[01:51:53] <Sweeper> I dunno
[01:51:53] <jmkasunich> whatever was in there is the thing you are looking for
[01:52:03] <Sweeper> that's the thing, I wasn't really paying attention
[01:52:13] <Sweeper> I got it from scrap, so it may have been removed
[01:52:35] <Sweeper> interesting tho
[01:53:10] <Sweeper> so theoretically, you could make an extremely accurate mini-cnc machine if you were happy with a 8"x8" work area
[01:53:24] <jmkasunich> not neccessarily
[01:53:53] <jmkasunich> I doubt they are using quadrature (I could be wrong, but they don't need to use quadrature - they know which way the carriage is moving
[01:54:15] <jmkasunich> I bet they also interpolate between the lines on the strip - the lines are nowhere near as fine as the DPI
[01:54:41] <Sweeper> well, there are 4 sensor contacts
[01:56:10] <jmkasunich> might be quad then
[01:57:06] <Sweeper> err, s/contacts/pin
[01:57:15] <Sweeper> I think one is ground tho
[01:57:41] <Sweeper> since it's common with one of the LED pins
[02:04:05] <lerman_> lerman_ is now known as lerman
[02:11:22] <jmkasunich> probably power, ground, and the two phases of the encoder
[02:11:45] <jmkasunich> although it could also be LED power, LED ground, phototransistor collector, phototransistor emitter
[02:12:09] <jmkasunich> without a really close look at the part its hard to tell, but my guess from the photos is the latter
[04:04:07] <lerman_> lerman_ is now known as lerman
[06:04:07] <lerman_> lerman_ is now known as lerman
[08:04:09] <lerman_> lerman_ is now known as lerman
[08:35:41] <archivist> * archivist reads the scrollback, I used to write/work on the DC motor speed control in printers
[08:40:13] <archivist> software counter giving regular ints, ints tests infront or behind opto mark, speed up or slow down to suit, (was an early implementation so was hard on off)
[08:40:30] <archivist> 6809 assembler
[10:04:10] <lerman_> lerman_ is now known as lerman
[10:58:56] <archivist> * archivist laffs, Fanuc invite to Mach show in the UK, hehe they just dont realise.....EMC RULZ here at least
[12:04:22] <lerman_> lerman_ is now known as lerman
[13:32:01] <tomp> jepler: installing a separate GL lib worked! thanks.
[13:32:25] <tomp> being unfamiliar with the process, ended up with a 10 meg recording first time
[13:33:49] <alex_joni> http://www.techamok.com/forum/viewtopic.php?t=7233
[13:34:06] <tomp> but it captured the 5axis and the cursor and AXIS fine
[13:34:52] <tomp> while(!fubarred) :)
[13:36:53] <tomp> do{msg("PleaseWait");} while (1)
[13:38:41] <archivist> good one alex_joni
[13:40:11] <skunkworks_> tomp: captured a video of axis?
[13:41:05] <tomp> yep, i needed to install vncrec, do 4 ln's and install a separate mesagl-lib, and it records smooth :)
[13:41:32] <skunkworks_> is it up anywhere?
[13:41:46] <skunkworks_> * skunkworks_ likes watching emc videos.
[13:41:47] <tomp> i need to learn how to turn the recording into more easily distributed media ( its .vnc now )
[13:42:10] <tomp> skunkworks_: no , not up yet, and is a recording of my fumbling right now ;)
[13:42:26] <tomp> but will use it for examples of EMC2/AXIS
[13:42:38] <tomp> for the wiki
[13:43:39] <tomp> the bugger was the gl windows wouldnt show up or would be doggy slow, now the mouses showed as very smooth
[13:44:04] <tomp> and i got to wiki up the logs of what was done into something others can reproduce
[13:44:51] <skunkworks_> Nice work
[13:44:56] <tomp> SWPadnos found the TK bits that needed ln's. Jepler found the vncrec app and the need for the >>extra<< gl lib
[15:09:11] <skunkworks_> boy - the crazies are out again now that gas prices are up. perpetual motion sell I guess.
[15:48:33] <alex_joni> actually I think I was wondering if it still worked on 2.4
[15:48:33] <alex_joni> kernels, after one of ****'s FUD storms
[15:48:38] <alex_joni> sorry ;)
[15:48:53] <alex_joni> http://www.220.ro/Pipilica_si_politia-68928.html <- proper paste
[15:50:41] <cradek> probably a bad idea.
[15:53:26] <SkinnYPupp> alex_joni: good one haha!
[15:59:28] <Guest933> Hello, I'm Jeff Witz from LMT-CACHAN france.
[16:00:25] <Guest933> I'm interested in linuxcnc, I tried it lkast year but there was a big limitation for me
[16:01:34] <Guest933> I want to use a realtime OS to make an open source platform for experimental laboratory.
[16:02:15] <Guest933> In order to control Test Machine real time machine is the point to be satisfied
[16:03:08] <Guest933> but in experimental mechanics we need to have some retro action with mesured quantities as displacement and forces
[16:03:37] <Guest933> For this purpose a Digital Acquisition Card is need.
[16:04:34] <Guest933> On linux there is a collection of dreivers called COMEDI, that allows one to acquire data and drive output.
[16:05:52] <Guest933> The main difficiulty with this, is that the kernel sources of linux and RTAI are nedeed to compile this software.
[16:06:32] <archivist> Guest933, get the live cd it has everything built including the realtime kernel
[16:06:59] <Guest933> The last time I tried linuxcnc there were no linux and rtai sources directories so I can't use COMEDI.
[16:07:04] <jepler> once you've installed the emc2 live cd, you can obtain the sources for emc2 and rtai using the "apt-get source" command, and you can obtain the source to the kernel using "apt-get install linux-source-<version number>"
[16:07:41] <Guest933> but is this the source of the patched kernels ?
[16:07:50] <jepler> yes.
[16:08:14] <Guest933> great !
[16:08:44] <jepler> here's the correct version number for the patched linux kernel: apt-get install linux-source-2.6.15-magma
[16:09:12] <Guest933> and for RTAI ?
[16:09:51] <jepler> apt-get source rtai
[16:10:09] <Guest933> ok thanks a lot !
[16:10:35] <jepler> depending what you're doing, you may only need to install the development packages
[16:11:49] <Guest933> the probleme is the complexity for compiling COMEDI
[16:12:01] <jepler> OK, you know the requirements of comedi and I don't.
[16:12:24] <jepler> I am a bit surprised it requires that you recompile the kernel, though
[16:13:12] <Guest933> I need to have the sources of RTAI and LINUX and to compile it with different options, so I need to the configuration files of the two kernels
[16:23:04] <Guest933> No it doesn't need to recompile a kernel, but sometime some options in the kernel configuration make failed the compilation of COMEDI, so as I don't kow what are the options you choose I can't tell you if it will work or not !
[16:23:54] <cradek> on debian based systems, the kernel config file that matches an installed kernel can always be found in /boot
[16:24:15] <Guest933> One thing sure is that I need the sources of both rtai and linux to compile COMEDI with real time support
[16:26:00] <Guest933> ok thanks
[16:28:29] <Guest933> I'm not a good in compiling software, so I make a lot of newbies mistakes.
[16:29:39] <Guest933> For now I haven't a lot of time to try it but as I have now a dedicated laptop to experimental sciences I will plan a linuxcnc installation.
[16:30:16] <Guest933> Thank you all for your precious answers. I realize that I had to come last year on this channel.
[16:30:24] <Guest933> Bye
[16:51:03] <acemi_> there is a page which describes how to compile comedi and rtai in debian etch in linuxcnc's wiki
[17:22:23] <Hugomatic> Hi, I'm writing a little python that generates gcode from Axis and I would like to use a tree widget as the main UI to set the values (I would like DND and check boxes). I can't find anything about this in tkInter. Any one can point me to a sample? thanks
[17:37:05] <Hugomatic> Here's another question: do you recommend sticking with tkinter or switching to another toolkit (wxPython, pyGtk or pyQt)? What are you guys using?
[17:39:45] <fenn> pygtk is nice
[17:40:46] <Hugomatic> fenn: thanks, I'll have a look at once. I'm browsing wxPython doc and there's no mention of trees.
[17:41:13] <fenn> www.pygtk.org/pygtk2tutorial/examples/basictreeview.py
[17:41:27] <tomp2> Tkinter tree widget (available from http://home.cfl.rr.com/genecash/)
[17:41:36] <fenn> i still havent figured out how to do DND
[17:42:06] <Vq^> i did some tests with that once
[17:42:22] <tomp2> tkinter tree widget http://py.vaults.ca/apyllo2.py/33109499
[17:42:30] <Hugomatic> tomp2: I had a look at the cash tree, but I would It does not allow tree items to have a checkbox
[17:43:04] <Vq^> fenn: as i recall it was quite complicated :/
[17:44:47] <Hugomatic> I want each tree item to correspong to gcode snippets (circles, squares, slots, etc..), with nested snippets... and I want to enable, disable them individually.
[17:45:25] <tomp2> fenn: http://sourceforge.net/projects/tkdnd
[17:46:40] <fenn> heh http://sourceforge.net/projects/lcars24/
[17:46:59] <fenn> that could be useful for touchscreens actually
[17:47:29] <Hugomatic> fenn: you have a touchscreen on your milling machine?
[17:47:31] <tomp2> Hugomatic: so the 'allow' part is the 'checkbox' part. why would tree have stuff that is not wanted? meaning, why not build the tree from stuff thats desired
[17:47:53] <tomp2> unless tree was a 'library'
[17:47:53] <fenn> Hugomatic: i have some industrial touchscreens with bad backlight inverters.. will get them running some day soon
[17:48:41] <fenn> pygtk allows you to put pretty much any widget in a tree element
[17:49:08] <Hugomatic> tomp2: sometimes, I make mistakes, and Axis shows too many lines for me to be able to pin point the problem. So If I can disable certain operations, I can see clearly. Also, sometimes I want to skip machining that's already been done
[17:49:30] <alex_joni> http://www.goodcnc.com/C000026.htm#
[17:49:39] <alex_joni> 10 points for whoever finds the first odd thing
[17:50:05] <Hugomatic> fenn: I think you're right, pygtk seems to be the one with most features.
[17:50:52] <tomp2> jkkmobile has several small touchscreen hacks
[17:51:00] <Hugomatic> LCARS rock!
[17:52:23] <tomp2> just xy? i dont see any z, and the emc penguin not under emc
[17:52:48] <alex_joni> tomp2: :) funny.. ain't it?
[17:57:14] <cradek> alex_joni: funny
[17:57:38] <tomp2> alex_joni: look at the teeny cnc control http://www.goodcnc.com/C000027.htm
[17:58:44] <tomp2> 2D/3D-HPGL
[18:02:05] <tomp2> even smaller mills and lathes and dros too
[18:02:33] <tomp2> showroom is http://www.goodcnc.com/products.asp
[18:03:38] <tomp2> materials and forms http://www.goodcnc.com/yj.htm
[18:04:09] <Hugomatic> I have a Sherline and these look familiar. I wonder how much they cost
[18:09:06] <tomp2> they can be cheap ( definition #1) they can be cheap (definition #2)
[19:12:31] <awallin> anyone using OpenSuse? (not for emc, just in general)
[19:13:59] <alex_joni> awallin: not me
[19:14:30] <awalli1> friend wants to use it for OpenFoam, a CFD application
[19:27:21] <awalli1> what does block-delete do?
[19:28:53] <fenn> it's like an optional comment
[19:29:17] <cradek> if the BD switch is on, lines starting with / are ignored
[19:32:29] <awalli1> ah, ok. mostly for hand-written g-code then? I've mostly used CAM generated code
[19:33:39] <cradek> in some of my auto-generated gcode, I have some /M0 lines, so on the first few runs I can pause in certain places until I trust it
[19:34:15] <cradek> in this case I use it for "does the tool height look right?" after the initial move with a new tool
[19:34:38] <alex_joni> otoh, you have optional stop
[19:34:44] <alex_joni> M1 iirc
[19:34:45] <cradek> that's true too
[19:34:53] <cradek> (not sure if BOSS has that)
[19:35:03] <alex_joni> oh, but it has block delete?
[19:35:08] <cradek> don't know how useful block delete is. EMC didn't have it until fairly recently.
[19:35:11] <cradek> alex_joni: yes
[19:35:30] <alex_joni> I can imagine all sorts of evil things to do with it..
[19:35:41] <alex_joni> like closing different o-word loops
[19:35:53] <alex_joni> but.. it's only for hand-written code
[19:36:47] <cradek> it can potentially be used for evil. it pretty much lets you choose between two different gcode programs.
[19:47:52] <awalli1> hmh, is S500 some kind of default spindle speed?
[19:48:38] <cradek> zero is the default spindle speed in EMC
[19:49:23] <awalli1> AXIS show the various model G-codes in a display below the MDI line
[19:49:40] <awalli1> when that says S0, and I do spindle.forward from halui I get S=500
[19:50:48] <awalli1> when it says S321 (for example) setting the spindle on/off from halui works just fine
[19:50:54] <cradek> that's apparently hardcoded in halui
[19:50:58] <cradek> which seems ... odd
[19:51:10] <alex_joni> oh, the 500?
[19:51:14] <awalli1> but when it says S0 I get spindle-speed-out=500
[19:51:57] <alex_joni> awalli1: I'm not sure how you would expect it to work..
[19:52:10] <alex_joni> having S0 and pushing spindle on, not doing anything?
[19:52:40] <awalli1> M3 and M4, when run with S0 apparently do nothing, i.e. spindle swithces to forward or reverse, but with 0 RPM
[19:53:10] <awalli1> I would expect halui.spindle.forward to work like M3 and halui.spindle.reverse like M4
[19:53:23] <SWPadnos> halui sets the spindle speed to 500 if the spindle was off and you hit the indrease button
[19:53:41] <awalli1> I hit halui.spindle.forward
[19:53:47] <SWPadnos> err - the start button
[19:53:54] <alex_joni> awalli1: src/emc/usr_intf/halui.cc
[19:54:05] <SWPadnos> look at the function sendSpindleForward()
[20:03:30] <awalli1> when in 'run' mode, i.e. a program is running, why is the step arrow active in AXIS? it doesn't seem to do anything? is it legal to command step while in run mode?
[20:04:25] <cradek> good question
[20:05:01] <alex_joni> * alex_joni runs away screaming
[20:05:17] <awalli1> * awalli1 pauses alex_joni
[20:05:24] <cradek> yeah, surely alex touched that last
[20:05:30] <alex_joni> step/resume/pause gave me gray hair
[20:05:35] <cradek> he fixes it every couple months
[20:05:41] <SWPadnos> one possibility, unconfirmed, is that step while running is equivalent to pause
[20:05:51] <SWPadnos> or "go into single-step mode"
[20:06:00] <alex_joni> cradek: I know I touched it last.. that's why I hate every moment when it comes up
[20:06:01] <SWPadnos> but I don't know if it does that, or if it should do that
[20:06:13] <alex_joni> but I'm not sure if I moved all my "improvements
[20:06:14] <cradek> alex_joni: I really feel for you
[20:06:16] <alex_joni> but I'm not sure if I moved all my "improvements" to 2.2
[20:06:19] <awalli1> SWP: at least with my 2.2.4 simulator pressing the arrow while in run mode doesn't do anything
[20:06:28] <SWPadnos> ok
[20:06:30] <alex_joni> awalli1: sounds tolerable enough :D
[20:06:37] <SWPadnos> then maybe it should be grayed :)
[20:06:54] <alex_joni> can I put some of the gray hairs over it?
[20:06:55] <cradek> fwiw, 2.2 and trunk work the same
[20:07:18] <awalli1> yeah, just wondering what my pendant buttons should do while stopped/paused/running. I have two buttons so their function will change a bit depending on mode
[20:07:50] <cradek> I don't think I've ever used step on my big mill. I do use feedhold quite a bit.
[20:08:35] <cradek> (seems like feedhold is entirely equivalent to pause)
[20:10:07] <SWPadnos> with the exception that pause will execute a single move then stop, and feedhold will stop immediately
[20:10:27] <cradek> that's incorrect
[20:10:40] <SWPadnos> oh - I'm thinking of step, not pause
[20:10:41] <SWPadnos> nevermind :)
[21:31:08] <skunkworks_> I don't know what else to tell him. http://www.cnczone.com/forums/showthread.php?p=437243#post437243
[22:37:11] <renesis> guys guys
[22:37:25] <renesis> how old is the ubuntu on emc livecd?
[22:37:51] <renesis> i have nf6100 everything integrated driver and that ubuntu sucks at it
[22:38:05] <jmkasunich> Ubuntu 6.06 - june 2006
[22:38:13] <renesis> hmm
[22:38:53] <renesis> guys they are on number 7.10 now =(
[22:38:59] <renesis> will emc install into that ok?
[22:39:05] <jmkasunich> no
[22:39:10] <renesis> shitty
[22:39:16] <jmkasunich> 6.06 is a LTS (long term support) version
[22:39:36] <jmkasunich> making the RT kernel is a major project, we don't do it every 6 months when ubuntu does another release
[22:39:43] <renesis> hmm
[22:39:53] <jmkasunich> the next LTS release is 8.04, which is coming out very soon
[22:39:59] <renesis> will emc install on a vanilla kernel not so much issues?
[22:40:00] <jmkasunich> we are working on the RT kernel for that one
[22:40:25] <jmkasunich> sim will work on a vanilla kernel, but if you want machine control you need RT
[22:40:31] <renesis> lspci is like unkonwunknownunknownunknown
[22:40:53] <renesis> no im saying can i put the RT stuff into a vanilla kernel easy
[22:41:03] <renesis> or is that like what you guys do
[22:41:19] <renesis> like its working
[22:41:31] <jmkasunich> its not easy
[22:41:34] <jmkasunich> I've never done it
[22:41:45] <renesis> i have no net
[22:41:49] <jmkasunich> jepler and alex_joni have been working on the 8.04 version for a while now
[22:41:59] <renesis> everything else even the nvidia gfx i dont care about
[22:42:08] <renesis> i just want the net driver to work, its pushing the cnc ok
[22:42:25] <renesis> are they doing beta builds?
[22:42:45] <jmkasunich> yeah
[22:42:52] <renesis> ubuntu.com says i can download the beta
[22:43:00] <renesis> do you know if its pretty okay?
[22:43:06] <jmkasunich> dunno
[22:43:08] <renesis> mine is just open loop stepper pulsing
[22:43:10] <renesis> k\
[22:43:39] <renesis> ok so ask jepler or alex_joni about it or is there a link?
[22:43:58] <renesis> else i prob have to use mach i dont want to =(
[22:44:19] <renesis> or i guess not i can just rawk the 1.9GHz pc without net like its 1995
[22:44:20] <jmkasunich> what kind of a machine is this? laptop or something?
[22:44:42] <renesis> no is a cheapo integrated mobo and a 11.9GHz sempron
[22:44:46] <renesis> er, 1.9GHz
[22:44:54] <renesis> wow 12GHz would be so neat =\
[22:45:05] <jmkasunich> no slots? a NIC is about $20 these days (or less)
[22:45:23] <renesis> yeah i think i got natsemi chip nic somewhere
[22:45:30] <renesis> it has pci and pciex
[22:45:42] <jmkasunich> stick it in there and call it good
[22:45:44] <renesis> its just so sexy without anything attached
[22:45:57] <renesis> yeah i have to find it first =\
[22:46:04] <renesis> all my mobos for years got nic onboard
[22:46:33] <renesis> ok ty i will ask jepler or alex_joni about new emc
[22:47:13] <SWPadnos> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Preparing_other_versions_of_Linux_to_compile_emc2
[22:47:34] <renesis> hmm
[22:47:41] <SWPadnos> there are experimental packages for 7.10 as well
[22:47:43] <renesis> swpadnos: k i will read and maybe try
[22:47:47] <SWPadnos> http://linuxcnc.org/experimental/gutsy/
[22:47:57] <renesis> k ty more
[22:48:34] <SWPadnos> there's another site I don't recall at the moment, which tells how to do RT on 7.10 (or 7.04)
[22:49:14] <acemi_> http://www.britishideas.com/2007/11/07/how-to-install-emc2-on-unbuntu-710-gutsy-from-scratch/
[22:49:32] <SWPadnos> yeah, that one :)
[22:51:02] <renesis> neat
[22:51:13] <renesis> ok so maybe i can do it with instructions
[22:51:32] <SWPadnos> hopefully. there aren't many people who can help you if those instructions don't do it :)
[22:51:47] <renesis> The process looks like this:
[22:51:47] <renesis> Get a vanilla kernel and patch it with RTAI support.
[22:51:47] <renesis> Test kernel.
[22:51:47] <renesis> Build and test RTAI modules.
[22:51:48] <renesis> Build EMC2.
[22:51:53] <renesis> classic
[22:52:06] <acemi_> renesis: if debian lenny (with 2.6.22 kernel) is OK for you, there are .deb packages for it
[22:52:17] <renesis> so like, i get the kernel to work with my hardware
[22:52:23] <renesis> i patch the shit with rtai
[22:52:30] <renesis> i pray
[22:52:33] <SWPadnos> install 7.10, then do this stuff on that clean install
[22:52:41] <renesis> and if everything works out rtai should work and emc should build
[22:52:51] <renesis> and people will laugh and play and dance in the streets etc
[22:52:52] <SWPadnos> that's the idea, yes
[22:52:58] <SWPadnos> except the last part
[22:53:00] <renesis> ok ive done that before
[22:53:04] <jepler> renesis: the 8.04 debs of realtime kernel and emc2 are at http://dsplabs.cs.utt.ro/~juve/tempdebs/hardy/
[22:53:04] <renesis> but it was with 300MHz
[22:53:16] <SWPadnos> it will be faster with 1.9 GHz
[22:53:17] <renesis> so yeah maybe 1.9GHz wont be as frustrating
[22:53:20] <renesis> o hai jepler
[22:53:23] <jepler> renesis: they are kind of at a "use at your own risk, and give us useful feedback if you can"
[22:53:36] <renesis> oh good at that i bitch in here all the time
[22:53:43] <renesis> sometimes its not even me being stupid
[22:53:44] <SWPadnos> that's not the same thing
[22:53:51] <renesis> kinda =\
[22:54:26] <renesis> do you guys have a bugzilla or you just use mailing lists?
[22:54:34] <SWPadnos> there's a sourceforge tracker
[22:54:37] <renesis> or your bugzilla is like secret sauce status
[22:54:47] <renesis> is it tracked by devs?
[22:55:05] <SWPadnos> maybe the list is a better place for comments about a beta release (or maybe not)
[22:55:14] <renesis> well fuckit ill use it if nothing happens ill pass out violins and cry about it
[22:55:43] <renesis> jepler: kk ill see if i can make it spin
[22:55:53] <renesis> i have 15 days to return this mobo if i hate it!
[22:56:02] <renesis> 14
[22:56:38] <renesis> but yeah i really dont want to, $100 core system was pretty wtf spiffy
[22:57:16] <renesis> okay
[22:57:22] <renesis> actually ill do that tomorrow
[22:57:39] <renesis> today ill just rawk a nic card i want to make shit fuck linux hax0ring thats so 2 years ago
[22:57:53] <renesis> k thank you cnc peoples bye
[22:57:55] <SWPadnos> um. yeah
[22:57:58] <SWPadnos> see you
[23:00:32] <jmkasunich> freaking weird: http://www.youtube.com/watch?v=DDfZdfeJ1nc&feature=related
[23:04:27] <cradek> wow, there's some unexpected resonance of some kind there
[23:04:31] <cradek> how bizarre
[23:05:12] <dmess> storm sewer surges are wicked... we get them on our street all the time... or the pipe blows thru and wrecks another drivway 3-4 times a yr
[23:06:22] <dmess> we have a creek in the backyard... it flows up and down 6 ft.. im ginna list this place as waterfront property... some days
[23:06:31] <SWPadnos> I've seen that video before, but I think I didn't see the second spurt
