[03:38:10] <SWPadnos> has anyone tried this drawing program? http://www.xaraxtreme.org/
[03:38:20] <SWPadnos> it looks like a Corel-alike
[03:38:31] <SWPadnos> (probably missing some features, but looks pretty capable)
[04:09:25] <JymmmEMC> SWPadnos: Corel dont do 3d though =)
[04:09:50] <SWPadnos> they had a 3D package a long time ago, but it certainly wasn't CAD
[04:09:55] <SWPadnos> Corel3D actually :)
[04:12:10] <tomp> it wouldnt build when i tried, dep hell. but now they have tgz, will try it out (had svg ;)
[04:15:51] <tomp> wow dload was fast, but i'll have to try it on a screen bigger than this eeepc, l8r!
[04:17:18] <SWPadnos> heh
[04:17:30] <SWPadnos> maybe my 3840x2400 screen?
[04:23:03] <tomp> oooh sexy buttons, and a great rusty look for machine tool guis http://downloads.xara.com/opensource/images/screenshots/general/07.jpg
[04:23:16] <SWPadnos> heh
[04:23:19] <tomp> a rusty skin for axis?
[04:26:32] <SWPadnos> a YPERREALISTIC one
[04:33:51] <tomp> oops, that artist, simone is a guy http://www.pampado.info/home.html , aw, the tutorials section is under construction :(
[11:03:54] <piasdom> g'mornin all
[11:06:38] <piasdom> SWPadnos:ran the latency test all nihgt and got 25322 ovl max and no overrun...this ok ?
[11:11:44] <alex_joni> piasdom: yes
[11:12:24] <piasdom> alex_joni: great...thanks
[11:53:22] <piasdom> now in stepconf..i have 15000 in the latency test result(was there when i opened step) should i change that ?
[11:54:08] <BigJohnT> yes
[11:54:51] <piasdom> to 25000 ?
[11:55:10] <piasdom> then work from there
[11:57:17] <BigJohnT> what was your max jitter?
[11:59:09] <piasdom> i had 25322 ovl max in terminal test...is that the same as jitters ?
[12:00:11] <BigJohnT> I don't remember... seems like it is
[12:00:44] <piasdom> i ran the terminal test instead of the other...thought they were the same
[12:01:30] <piasdom> jepler sent me a web link to run that test
[12:02:55] <BigJohnT> I guess it is the same but it has been a while since I used the terminal one
[12:04:17] <BigJohnT> yep looks like ovl max is the same as max jitter
[12:05:32] <piasdom> so work from 25000 /
[12:05:33] <piasdom> ?
[12:05:46] <BigJohnT> yes
[12:06:02] <piasdom> cool thanks BigJohnT
[12:06:09] <BigJohnT> np
[12:06:48] <BigJohnT> if you get the rtapi error just increase it
[12:08:16] <piasdom> ok
[12:09:13] <piasdom> in my ini file..i have 70000 for base_period and 1000000 for servo...this ok ?
[12:10:13] <piasdom> servo_period
[12:10:36] <BigJohnT> did you use the stepconf wizard to generate your config?
[12:12:07] <piasdom> i was in my ini file before...wanted to finish that before goiong to step
[12:12:39] <piasdom> thinking about it now....that will change when i run stepconf..right
[12:12:46] <BigJohnT> yep
[12:12:48] <piasdom> k
[12:29:32] <piasdom> now get this http://pastebin.com/m3462f02d
[12:37:56] <BigJohnT> looks like the rtai did not get unloaded just try it again
[12:38:36] <piasdom> stepconf ?
[12:38:48] <piasdom> should i reboot ?
[12:38:52] <BigJohnT> no your my-mill
[12:38:54] <BigJohnT> no
[12:38:56] <piasdom> k
[12:39:37] <alex_joni> that looks like running stepconf while emc2 is running
[12:40:22] <BigJohnT> I was just guessing :)
[12:44:26] <piasdom> not open
[12:54:18] <BigJohnT> piasdom: does it work now?
[12:54:45] <piasdom> no sir
[12:55:44] <piasdom> how high can i go ?
[12:55:58] <BigJohnT> aww don't call me sir... I'm a redneck
[12:56:16] <piasdom> <-----coonass hhahahha
[12:56:25] <BigJohnT> from where?
[12:56:32] <piasdom> louisiana
[12:56:38] <BigJohnT> I knew that :)
[12:56:44] <piasdom> lafayette
[12:57:02] <BigJohnT> cool I used to live in LaPlace and Metairie
[12:57:20] <piasdom> an hour away
[12:57:21] <BigJohnT> ok better question did EMC load
[12:57:36] <BigJohnT> now I'm in swamp east Missouri
[12:57:36] <piasdom> no...just gif and error
[12:57:46] <alex_joni> piasdom: open terminal
[12:57:54] <alex_joni> halcmd stop
[12:57:55] <BigJohnT> thanks Alex
[12:57:56] <piasdom> nothing like louisiana swamp :)
[12:57:57] <alex_joni> halcmd unload all
[12:58:08] <alex_joni> sudo /etc/init.d/realtime stop
[12:58:21] <piasdom> how do start hal (damn lazy ahl :)
[12:58:29] <piasdom> k
[13:00:13] <piasdom> don't know if this is the same error http://paste.org/index.php?id=4816
[13:00:51] <piasdom> i got this in terminal ERROR: Module hal_lib does not exist in /proc/modules
[13:01:43] <Guest859> Guest859 is now known as skunkworks_
[13:03:54] <alex_joni> piasdom: sudo /etc/init.d/realtime start
[13:03:57] <alex_joni> does that work?
[13:04:06] <alex_joni> if it works, then use stop
[13:04:10] <piasdom> ok
[13:04:32] <piasdom> insmod: error inserting '/usr/realtime-2.6.24-16-rtai/modules/rtai_hal.ko': -1 File exists
[13:04:38] <piasdom> that is using start

[13:09:45] <eric_unterhausen> sudo rmmod latency_rt
[13:10:48] <piasdom> k
[13:11:22] <piasdom> something happened >
[13:11:24] <piasdom> ?
[13:12:37] <eric_unterhausen> now try stop again
[13:12:48] <piasdom> k
[13:13:09] <piasdom> does not exist
[13:13:21] <eric_unterhausen> we knew that
[13:13:50] <piasdom> that is what i get using stop...a lot of files don't exist
[13:14:11] <eric_unterhausen> are you still getting in use errrors?
[13:14:27] <eric_unterhausen> if it doesn't exist, it's not a problem
[13:14:32] <eric_unterhausen> on stop
[13:14:38] <piasdom> can't get to use....just error message
[13:15:13] <piasdom> now it opened :)
[13:15:25] <piasdom> i'm in mini now
[13:15:53] <eric_unterhausen> are you supposed to be in mini?
[13:16:19] <piasdom> yes..i perfer mini
[13:17:08] <piasdom> thannks for ya'll help
[13:28:03] <eric_unterhausen> he needs to buy higher quality string for that connection
[13:33:02] <fragalot> a G-string?
[13:33:22] <eric_unterhausen> I don't wanna think about what he might do with that
[13:33:39] <fragalot> put it on his piano, because he broke it while fingering a minor?
[13:33:41] <archivist> play a tune
[13:33:48] <eric_unterhausen> can you imagine a couple of kids trying to make a communications system with two cans and a gstring?
[13:35:59] <alex_joni> only with a couple of gstrings
[13:37:16] <eric_unterhausen> can you hear me? you're yelling in my ear!
[13:38:39] <piasdom> ok, ya'll got mini working (THANKS) but.............
[13:39:11] <piasdom> how do i ajust the accuracy...g01 move about 1.125
[13:39:53] <alex_joni> piasdom: are you familiar with an abacus?
[13:41:06] <piasdom> yes...but i don't like where this is going :)
[13:41:46] <piasdom> ok
[13:42:14] <alex_joni> piasdom: kidding
[13:42:23] <alex_joni> you only need to fill out the proper values here: http://www.linuxcnc.org/docs/devel/html//stepconf-axis.png
[13:42:48] <piasdom> thanks.....i was just waiting :)
[13:43:31] <piasdom> microstepping ?
[13:43:45] <alex_joni> piasdom: you do have a step motor driver.. right?
[13:43:59] <alex_joni> sqarish box with wires sticking out of it
[13:44:11] <piasdom> yes sherline
[13:44:12] <alex_joni> usually has some leds on it
[13:44:19] <piasdom> hahahahaha
[13:44:19] <alex_joni> ok, I bet a manual comes with it
[13:44:28] <piasdom> i got the idea
[13:44:30] <piasdom> nnl
[13:44:31] <alex_joni> ;)
[13:44:45] <alex_joni> iirc, for sherline there's a jumper to select the number of microsteps
[13:45:55] <shrdlu-> is there a way I can test my home sensor is working in linux? something like a gui parallel tester?
[13:47:22] <skunkworks_> is emc installed on your computer?
[13:47:38] <shrdlu-> yes
[13:48:08] <alex_joni> shrdlu-: start one of the sample stepper configs
[13:48:21] <alex_joni> then under the AXIS menu you have a link to "hal meter"
[13:48:46] <skunkworks_> Then use halscope or hal meter - and pick the pin you want to look at.. ^what alex_joni said.
[13:49:09] <alex_joni> the pin you want to look is probably something like parport.0.pin-xx-in
[13:49:12] <alex_joni> or -in-not
[13:49:27] <shrdlu-> oh, nice, thank you
[13:49:35] <alex_joni> shrdlu-: http://www.linuxcnc.org/docs/devel/html//halmeter-demo-1.png
[13:49:44] <alex_joni> that's how halmeter approximately looks like
[13:50:38] <skunkworks_> You can run more than one also.
[13:54:47] <steves_logging> steves_logging is now known as steve_stallings
[13:56:09] <eric_unterhausen> you guys are special
[13:57:03] <shrdlu-> needs?
[13:57:53] <alex_joni> eric_unterhausen: you'd think so
[13:57:57] <alex_joni> shrdlu-: sorry?
[13:59:32] <eric_unterhausen> what?
[13:59:43] <alex_joni> eh?
[13:59:56] <alex_joni> 15:51 < eric_unterhausen> you guys are special | 15:52 < alex_joni> eric_unterhausen: you'd think so
[14:01:56] <eric_unterhausen> eric_unterhausen is now known as unterhausen
[14:02:15] <shrdlu-> hm, my sensor doesn't seem to be doing anything
[14:02:28] <unterhausen> what sensor is that?
[14:02:44] <shrdlu-> home sensor, optical i guess
[14:02:51] <shrdlu-> I dunno, this is a retroft
[14:03:05] <unterhausen> is it plugged in?
[14:03:33] <shrdlu-> as far as I am aware
[14:03:50] <unterhausen> to what?
[14:04:08] <archivist> scope or meter check wiring
[14:04:23] <archivist> does it need a pull-up
[14:04:46] <shrdlu-> I will have to check all that
[14:05:15] <shrdlu-> well, I know where it's plugged in, pin 10 of the parallel port
[14:05:24] <unterhausen> is it a switch?
[14:05:27] <shrdlu-> just hooked up to the breakout I made for the ribbon
[14:05:39] <shrdlu-> it's optical
[14:05:50] <shrdlu-> but err
[14:05:59] <unterhausen> k
[14:06:32] <alex_joni> does it have a check light on it?
[14:06:34] <alex_joni> most do..
[14:07:07] <shrdlu-> I can't really get at it to see, I dont think it does
[14:09:23] <unterhausen> voltmeter probably a good first pass
[14:10:06] <fragalot> and if all else fails, lick it
[14:10:08] <fragalot> * fragalot hides
[14:10:31] <unterhausen> you can't hide on the internet
[14:10:38] <fragalot> yes I can
[14:10:45] <fragalot> all it takes is "/me hides"
[14:11:10] <archivist> ah but I know where you hide in other channels
[14:11:48] <archivist> * archivist found fragalot yawning in #electronics this morning
[14:12:01] <fragalot> archivist: prove it
[14:12:02] <unterhausen> did you see the U.S. state department IT system was almost taken down by an empty email?
[14:12:04] <fragalot> * fragalot hides again
[14:12:18] <fragalot> * fragalot unhides to query unterhausen about the details
[14:12:33] <unterhausen> http://news.yahoo.com/s/ap/20090110/ap_on_go_ca_st_pe/state_department_e_mail
[14:13:06] <fragalot> fail
[14:14:06] <unterhausen> I've gotten emails with long cc lists from government agencies, it's a problem waiting to happen for a lot of them
[14:14:46] <fragalot> I never get emails from government agencies
[14:14:48] <fragalot> \o/
[14:15:31] <unterhausen> it's pretty common at universities
[14:16:16] <fragalot> I don't have that issue, all emails i get from my uni originates from <insert random gibbrish here>
[14:16:26] <fragalot> the mail system is.. crap, to say the least
[14:16:53] <unterhausen> we have a spam filter which doesn't work
[14:17:10] <unterhausen> lots of professors have spam filters that send gmail and yahoo to spam automatically
[14:18:24] <unterhausen> I told them that the number of people on their system that want to receive emails about viagra is almost zero
[14:18:33] <fragalot> lol.
[14:18:57] <unterhausen> I don't know how you have a spam filter that doesn't hit that one hard right up front
[14:26:55] <unterhausen> I need to figure out how to change the name that people see when I call them on my cellphone
[14:30:02] <BigJohnT> borrow someones phone when you call
[14:30:20] <unterhausen> I would like them to see my name instead of my wife's
[14:31:20] <unterhausen> they have a way to change it on the web site, but it doesn't work
[14:39:19] <unterhausen> any good web hosting companies out there?
[14:40:27] <jepler> unterhausen: linuxcnc.org uses dreamhost.com. but dreamhost emphasizes "cheap" over "reliable" and "fast"
[14:40:56] <archivist> * archivist self hosts
[14:40:59] <unterhausen> I don't need much, hacker "proof" is somewhat important
[14:41:53] <unterhausen> there is a domain parking company that has my domain name though
[14:44:52] <skunkworks_> I have used hasweb and hostdime. (really the same company)
[14:45:37] <skunkworks_> I think I pay $48 a year thru hasweb
[14:46:44] <archivist> disk space is my main requirement and dns so I can run a few sites
[14:51:15] <unterhausen> I need a legit email address other than the one at the university
[14:52:34] <archivist> do you want a gmail ?
[14:53:54] <unterhausen> I have gmail
[14:53:56] <maddash> do you want a gmail ?
[14:54:09] <unterhausen> I'm thinking that might not make some people happy though
[14:55:13] <archivist> I think I would only want a "better" one for company/commercial type emails
[14:55:22] <unterhausen> that's what I want
[14:55:59] <archivist> then tied to your domain can look better then
[14:56:54] <unterhausen> that's what I'm thinking
[14:57:29] <archivist> Ive been too idle to set that up yet
[14:58:02] <unterhausen> Idle is a perfect word for my entire existence
[14:58:50] <unterhausen> I have a web site at the university which I haven't edited in 8 years
[14:59:49] <archivist> idle++
[15:00:10] <archivist> my archive site is a year or two
[15:03:40] <archivist> but with the boss selling the land here I need to get a fixed IP at home or a good cheap hosting deal
[15:09:46] <unterhausen> there was a short time that my name was available as a domain
[15:10:00] <unterhausen> don't know if I want to use that anyway, a guy with my name was murdered
[15:10:28] <archivist> I got archivist.ifo it suits me
[15:10:32] <archivist> info
[15:10:33] <unterhausen> it's still the first hit on google
[15:11:07] <unterhausen> then there was a guy with my name that was charged with securities fraud
[15:11:25] <archivist> hehe
[15:11:57] <archivist> change your name
[15:12:29] <unterhausen> anonymity has some advantages
[15:13:06] <archivist> yup
[15:13:11] <alex_joni> change it to anonymity
[15:13:23] <alex_joni> eric anonymity
[15:13:30] <unterhausen> anonymity through repetition works for me
[15:13:32] <archivist> anonymity.com
[15:13:38] <unterhausen> probably taken
[15:15:19] <unterhausen> yeah, it's a anonymizer
[15:17:52] <alex_joni> unterhausen: you can still get anonymizer.ro, and way cheaper ;)
[15:39:55] <unterhausen> alex_joni: I'll take that under advisement
[15:40:55] <unterhausen> I can get my name .net
[15:46:26] <skunkworks_> not any more.. ;)
[15:46:43] <skunkworks_> * skunkworks_ is kidding
[15:55:09] <archivist> * archivist is happy, just got the manual from the states for the HP dynamic system analyser
[15:56:00] <archivist> when repaired I can test/measure mechanical systems
[16:01:49] <unterhausen> I always dreamed about having one of those, did you get one of the magic hammers?
[16:03:23] <archivist> no it has a noise source in it to stimulate the system under test
[16:04:07] <unterhausen> how do you inject the noise into a mechanical system?
[16:04:42] <archivist> a shaker
[16:04:48] <unterhausen> cool
[16:05:06] <archivist> which is a glorified speaker coil on steroids
[16:05:24] <unterhausen> I recently speculated that the number of used shakers was reduced considerably by the price of copper
[16:05:27] <archivist> or could be ones servo
[16:05:48] <unterhausen> I have a small shaker that I bought a while back that has no windings due to that
[16:06:33] <archivist> next thing to google fleabay for I suppose
[16:07:03] <unterhausen> you never know where they might be hidden there
[16:07:30] <unterhausen> we have a batch of little shakers at work, personally I like to shake things with hydraulics
[16:07:47] <archivist> descriptions for those could so easily be wrong
[16:07:50] <unterhausen> more scary
[16:08:18] <archivist> I have some accelerometers and charge amps
[16:09:00] <unterhausen> that's really what you need, assuming the machine isn't totally dead
[16:12:21] <archivist> dont think my accelerometers go down to a low enough rate, need to look the data up
[16:14:50] <archivist> but it adds up to good brochure BS for a website of facilities
[17:33:22] <shrdlu-> hm, looks like my sensor is toast :/
[17:34:05] <archivist> what sort is it
[17:38:30] <shrdlu-> tcst1030 opto switch
[17:38:33] <shrdlu-> u shaped
[17:45:53] <shrdlu-> now to find somewhere in the uk that sells them or similar without a minimum order price
[17:53:29] <archivist> do you have the correct pull up etc
[17:56:25] <shrdlu-> It's on a pcb, it was working before
[17:56:55] <shrdlu-> i thought I was hooking it up wrong, but it's not even working with the original driver
[17:57:00] <shrdlu-> so I take it it's dead
[17:57:13] <archivist> or you killed it
[17:57:46] <archivist> local Maplin should have something
[17:58:02] <shrdlu-> I didn't see anything
[17:59:07] <shrdlu-> guess there are several names it could go under
[17:59:17] <archivist> farnell
[18:00:06] <archivist> even CPC
[18:00:07] <SWPadnos> rswww
[18:00:28] <shrdlu-> farnell has a £20 minimum order
[18:00:32] <shrdlu-> thus my comment above
[18:00:44] <shrdlu-> and I obviously killed it, who else would have done it?
[18:00:47] <shrdlu-> terrorists?
[18:01:32] <archivist> fleabay http://cgi.ebay.co.uk/Slotted-Opto-Switch-0PB865T55-X-4-NOS_W0QQitemZ120282279072QQcmdZViewItemQQptZUK_BOI_Electrical_Components_Supplies_ET?hash=item120282279072&_trksid=p3286.c0.m14&_trkparms=72%3A1301|66%3A2|65%3A12|39%3A1|240%3A1318
[18:02:52] <shrdlu-> that should do it, if they'll fit the pcb. thankyaw for looking
[18:14:40] <vent313> How can I patch my Ubuntu 8.04?
[18:15:45] <micges> what patch ?
[18:15:50] <vent313> I mean that RTAI or RTLinux patches.
[18:16:15] <vent313> to be able to use EMc2 as "real", not just as a simulator.
[18:16:15] <archivist> use the live CD its done for you
[18:16:30] <vent313> archivist: no, have no chance to use it
[18:17:01] <vent313> archivist: do i need to, as it's called, "re-compile kernel" ??
[18:17:45] <archivist> you have to add the realtime kernel there is some stuff on the wiki
[18:17:52] <alex_joni> vent313: if you want to do it yourself, then you must get rtai, get the kernel sources, patch them, then recompile
[18:18:16] <alex_joni> once you have a working kernel, you can compile rtai, then once that's working you can get emc2 sources and compile those
[18:18:36] <alex_joni> it should take a couple days if you're used to the process
[18:18:48] <archivist> so much easier to use the live CD
[18:18:53] <alex_joni> vent313: any reasons against using already compiled packages?
[18:18:57] <vent313> alex_joni: ok, i have kernel - and ... it seems too hard.
[18:19:14] <alex_joni> vent313: if it's the first time you do this.. it's certainly not easy
[18:19:40] <vent313> alex_joni: i have compiled python2.5 and emc, have no internet access - don't know if your package
[18:19:43] <vent313> ...with rtai will need dependencies
[18:20:49] <archivist> thats why we all recomend the live CD then you dont need web access
[18:21:04] <vent313> alex_joni: can you introduce me into "rtai" - or "rtlinux" - what is it? is it some kind of a program, which can be ./configure'ed, then make, make install'ed
[18:22:43] <BigJohnT> vent313: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Preparing_other_versions_of_Linux_to_compile_emc2
[18:23:53] <vent313> ok, thanks - i'm
[18:53:41] <shrdlu-> Home location: This is the location the machine will go to once it hits the home switch.
[18:53:58] <shrdlu-> so it triggers the switch, then goes to another location of your choosing?
[18:54:06] <alex_joni> shrdlu-: picture it like a G00 move
[18:54:20] <alex_joni> exactly
[18:54:37] <shrdlu-> presumably somewhere close by?
[18:55:07] <shrdlu-> well, that's what my old driver did anyway
[18:55:26] <shrdlu-> home, then about 1cm out from each axis (x,y only)
[18:56:31] <shrdlu-> I don't understand how it knows where the y axis home is though
[18:56:37] <shrdlu-> there seems to be only one home switch
[18:57:45] <SWPadnos> one physical switch?
[18:57:51] <SWPadnos> or one switch input?
[18:58:01] <shrdlu-> one physical switch
[18:58:24] <SWPadnos> interesting. is it a cam roller type, just a microswitch ...?
[18:59:17] <shrdlu-> it's two steppers on belts, xy for a laser, with an opto switch on the far right hand side of the x axis
[18:59:41] <shrdlu-> but it homes the y too, the original plotter board
[19:00:16] <SWPadnos> huh
[19:00:35] <SWPadnos> you can try things like starting a homing operation with X very close to home and Y far away, and see how it moves
[19:00:42] <SWPadnos> versus Y close to home and X far away
[19:00:57] <shrdlu-> I broke the sensor :/
[19:01:06] <SWPadnos> well, once you fix the sensor ;)
[19:01:15] <SWPadnos> does RS have a minimum order?
[19:01:34] <shrdlu-> heh, yeah I will do. I'd like to copy the startup procedure from the old board
[19:01:35] <archivist> a tab moving in from x and y so it could set both
[19:02:02] <SWPadnos> well, ideally you'd want to stop motion on any axis that has reached its home position
[19:02:17] <shrdlu-> I think RS has a minimum, either that or £6 postage
[19:02:20] <SWPadnos> then again, with steppers you can just hope the end stops are strong enough to stall the motors
[19:03:00] <archivist> he wants/needs better than that as its a laser plotter
[19:03:31] <SWPadnos> well, it's pretty repeatable, until you mushroom the end stop from repeated hammering ;)
[19:04:02] <SWPadnos> errand time. bbl
[19:04:46] <archivist> not a system I like as the stepper can cog either side of the stop if its not well defined
[19:05:22] <vent313> www.rtai.org uses an invalid security certificate. The certificate is not trusted because it is self signed. (Error code: sec_error_ca_cert_invalid)
[19:05:53] <maddash> ^--- "alex_joniit should take a couple days if you're used to the process" wtf? 'couple days'? it takes me 20 min to recompile a kernel, and another 10 min to compile emc
[19:05:55] <vent313> can someone give me a link to rtai-3.6.1.tar.bz2 @ http://www.rtai.org
[19:05:59] <archivist> hmm I need a variac for a test procedure on my power supply fault
[19:06:43] <vent313> maddash: i'm about to do it withing next few minutes!
[19:06:50] <maddash> vent313: have you read the wiki?
[19:06:51] <shrdlu-> damn i wish I had an endoscope
[19:06:57] <vent313> yes
[19:07:01] <vent313> just
[19:07:26] <shrdlu-> well, whatever the correct term for that is
[19:07:30] <shrdlu-> for non medical use
[19:07:50] <shrdlu-> hm, maybe I can look with a mirror
[19:07:56] <maddash> wget --no-check-certif https://www.rtai.org/RTAI/rtai-3.6.2.tar.bz2
[19:08:01] <maddash> from http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI
[19:08:01] <archivist> same device name for non medical
[19:08:22] <maddash> shrdlu-: into your GI tract? I don't think that's a good iea
[19:08:28] <vent313> oh my!? How could I know about it?
[19:08:45] <vent313> ah! it's night here where i am
[19:12:14] <vent313> ok, going off-line. this rtai cost 0.40 for my mobile phone, therefore, at the end of the download i will be offline :(
[19:13:14] <shrdlu-> * shrdlu- discovers the wonder of an inspection mirror
[19:14:06] <shrdlu-> well, I can see it all now, and I can't see any other sensor
[19:14:38] <motioncontrol> good evening today
[19:17:50] <motioncontrol> One question please.in my hal file i load the: loadrt hal_m5i20.this driver directory is m5i20 in emc , but what is the firmare load?4 or 8 axis?
[19:18:33] <jepler> the hal_m5i20 driver is 4-axis unless you modify and recompile emc. the new hm2_pci driver is more flexible.
[19:18:36] <cradek> I think that's a 4-axis configuration. a newer and more flexible driver is available called hostmot2
[19:20:11] <BigJohnT> motioncontrol: http://www.linuxcnc.org/docs/devel/html/drivers_hostmot2.html and more info in man hostmot2
[19:20:57] <alex_joni> the rtai binary package for ubuntu is way smaller than the source
[19:21:07] <motioncontrol> i have compile emc2.2.8 and i thing the driver hal_pci is compiled.For change the driver i select in menu start emc hm2_servo ?
[19:22:00] <jepler> motioncontrol: that set of files is designed for the 7i43 card, not the 5i20 pci card. However, looking at those files will give you some idea how a hm2_pci configuration would be
[19:23:04] <alex_joni> maddash: start with a new kernel version, lets see how much it takes
[19:24:03] <maddash> alex_joni: <1 hr
[19:24:05] <motioncontrol> please alex you have the hal and ini and core file for load the hal_pci for m5i20?
[19:24:11] <maddash> alex_joni: i'm running 2.6.25
[19:24:21] <maddash> alex_joni: unless by 'new' you mean 2.6.30
[19:24:44] <jepler> www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-12-25.txt
[19:25:03] <jepler> ^^ in this old irc log, jmkasunich heklped kimk adapt the hm2-servo configuration to a 5i22 pci card; the steps to adapt to 5i20 would be similar.
[19:25:26] <cradek> maddash: typing 'make; make install' and making working realtime-patched kernel deb packages that many people can use are very different tasks
[19:25:29] <vent313> alex_joni: b-t-w, i just have 2.6.25 on cd
[19:25:32] <alex_joni> maddash: lets say 2.6.27
[19:25:58] <alex_joni> vent313: what linux do you have installed?
[19:26:24] <maddash> cradek: alex_joni was referring to vent313 case specifically
[19:26:36] <alex_joni> maddash: nope, not specifically
[19:26:52] <alex_joni> it's probably gonna take him more than 2-3 hours to download the sources
[19:26:52] <motioncontrol> alex i'm old nickname is flexmotioncnc, remember problem for stop axis visualization?now is ok.the problem is the patchy 3.5-cv rtai with the 2.8.17 kernel.now i compile the 2.6.22 with 3.6-cv rtai , the problem not is present.
[19:27:08] <maddash> alex_joni: somehow, I don't think vent313 wants to create packages that 'many people can use' at this point
[19:27:31] <alex_joni> motioncontrol: good to hear that you fixed it
[19:27:34] <cradek> motioncontrol: that's very interesting
[19:27:56] <alex_joni> maddash: another nice example for things that "can" happen :)
[19:28:06] <cradek> maddash: maybe you're just that much smarter than alex, but if so, it's not polite to tell him
[19:28:17] <maddash> alex_joni: **at this point**
[19:28:45] <maddash> cradek: huh? when was I referring to 'smart-ness'?
[19:28:59] <cradek> forget it
[19:29:30] <cradek> it's just that he has done this task (built kernel, rtai, emc packages) and you haven't. so arguing with him about how long it takes (or ought to take) is silly
[19:30:22] <alex_joni> cradek: I don't deny that once stuff is in place it can take less than 1h on a moderately fast pc to rebuild everything
[19:30:43] <cradek> yes possibly
[19:30:56] <vent313> maddash: /usr/src/rtai/base/arch/***x86/patches/hal-linux-2.6.25-x86-2.0-07.patch*** or /usr/src/rtai/base/arch/***i386***/patches/hal-linux-2.6.25-x86-2.0-07.patch ??
[19:31:01] <maddash> i was pointing out that in vent313's case, it would take vent313 < 1 hr to compile a kernel for vent313 himself, unless vent313 compiles on a P3 or something
[19:31:04] <vent313> i386 or x86
[19:31:22] <vent313> celeron 2 GB 2 gb ram
[19:31:26] <vent313> laptop
[19:31:37] <alex_joni> vent313: you compile on 2.6.25 ? I'd take the x86
[19:31:42] <maddash> vent313: you're going to run emc on a laptop? did you read the wiki?
[19:32:14] <vent313> and reiserfs, but i've used to compile everything as e.g. wine in ramdisk in /dev/shm, which is 1gb in size
[19:32:38] <alex_joni> laptop is probably a poor choice for emc2
[19:32:44] <vent313> maddash: it's to show "the principals" of emc2 to co-workers
[19:33:03] <vent313> maddash: and why not? Can you tell me why not?
[19:33:19] <alex_joni> power management
[19:33:29] <alex_joni> that screws with realtime performance
[19:33:36] <vent313> laptop is in the cold room, so CPU's cooler will be ok in a test
[19:33:42] <archivist> vent313, latency issues, power shuts down the cpu
[19:34:00] <archivist> vent313, its battery saving not heat
[19:34:22] <vent313> shuts down the CPU? I can adjust /etc/laptop-mode/laptop-mode.conf then
[19:34:26] <maddash> alex_joni: oh you were talking about pre-compilation prep, like setting up dirs, patching etc? then you're right.
[19:34:26] <jepler> vent313: modern power management techniques such as the use of "SMI" to control fan speeds take control away from the operating system (including RTAI) for long periods of time.
[19:34:40] <vent313> archivist: i will do it on betteyr then. can i?
[19:34:41] <jepler> Disabling SMI voids your laptop's warranty and may cause actual physical damage
[19:34:49] <maddash> doh!
[19:34:57] <jepler> (it can on desktops too, though they don't have such thin thermal margins as laptops)
[19:34:58] <alex_joni> maddash: and chosing a proper config file, etc
[19:35:25] <vent313> jepler: i have no PC, only laptop, 32 bit... Will install it on pc then...
[19:35:46] <vent313> uh... :(
[19:36:23] <maddash> alex_joni: yes, in that case, i agree; menuconfig has me hooked for hours at a time
[19:36:28] <alex_joni> vent313: aren't there any internet cafe's around there?
[19:36:45] <alex_joni> some place you can go to and download the iso?
[19:36:49] <maddash> emc on gumstix
[19:37:10] <vent313> alex_joni: it's western siberia and snow and bears all around, no cafe, no coffee at all: crisis
[19:37:12] <vent313> :)
[19:37:39] <alex_joni> then it's surely out of walking (driving?) distance :)
[19:37:40] <archivist> * archivist does not believe its that bad
[19:37:57] <vent313> alex_joni: i can use beer&friend&non-limited internet access, but today i'm about to compile it\
[19:38:09] <vent313> j/k
[19:38:36] <vent313> archivist: /usr/src/rtai/base/arch/x86/patches/hal-linux-2.6.24-x86-2.0-07.patch or i386 architecture ??
[19:38:52] <vent313> which folser for a patch?
[19:38:54] <alex_joni> vent313: as I said, I would try the x86 patch first
[19:39:01] <vent313> ok
[19:39:07] <maddash> has anyone tried porting emc to arm yet?
[19:39:17] <archivist> hell no
[19:39:34] <archivist> * archivist programmed on ARM once
[19:40:08] <vent313> but, i have another question: what is RTAI? Is it a "strong defence" for ***performance*** and nothing else? What if I'm sure my laptop will handle that drawing realtime?
[19:40:31] <maddash> archivist: what's wrong with arm?
[19:40:41] <maddash> vent313: it won't. trust me, it won't.
[19:41:20] <alex_joni> vent313: RTAI is basicly a mini operating system, that will work besides linux
[19:41:21] <vent313> maddash: it will not run or i will trash the detal, (which i will mill)
[19:41:32] <vent313> alex_joni: ok, but...
[19:41:38] <archivist> maddash, strange short relative jmps, made for a broken C switch statement in some code I was working on
[19:41:45] <alex_joni> both run on the same PC, but linux has less priority than rtai
[19:42:06] <alex_joni> for this change from rtai to linux, back to rtai, etc to work the hardware is not supposed to stop processes
[19:42:36] <alex_joni> but on some laptops you can have special things that cause blocking the CPU too much, then rtai can't change and all your timings will be off
[19:42:55] <alex_joni> this is still ok to show how emc2 looks, but you can do the same with a simulation of emc2
[19:43:02] <alex_joni> e.g. compiled in simulator mode
[19:43:14] <alex_joni> (without needing a special kernel and rtai)
[19:44:00] <jepler> archivist: what compiler? I can't remember the last time I actually encountered a gcc bug on either of the platforms I commonly build for (x86 or avr)
[19:44:21] <vent313> ok. ah... well, it's my own laptop, and i hadn't planned to work using it. anyway, it seems my celeron isn't as sophisticated as e.g. intel cpu - so i hope i have no that SMI in bios or so. I'm using emc2 to visualize optimization of drawings at a current period
[19:45:14] <alex_joni> if you're not planning to physically control a CNC machine, then you can do the same things compiling emc2 in simulator mode
[19:45:22] <archivist> jepler, it was Acorns own compiler this was a long time ago
[19:45:31] <alex_joni> the only difference is that in simulator mode, emc2 can't control hardware
[19:45:56] <jepler> archivist: might be a whole new story these days
[19:45:58] <vent313> alex_joni: i plan a try, but wante to use laptop, will change my p.o.v - points of view
[19:46:33] <archivist> jepler, may well be but the underlying risc is still there
[19:47:22] <archivist> jepler, Im not following the chip these days, dunno if they improved the jmp range
[19:47:31] <vent313> anyway, i somehow think this mean-price laptop can offer such a trick to me. Just its
[19:47:48] <vent313> ..its BIOS is too simple for serious notebooks
[19:48:09] <vent313> ah, will see
[19:48:11] <jepler> archivist: it's up to the compiler to choose the right jump instruction(s)
[19:49:03] <archivist> jepler, yes I know it was buggy, (they did not like my bug reports)
[19:49:17] <vent313> why don't RTAI = buffer of RAM and some CPU timings (not big at all for such a task)?
[19:49:17] <archivist> I complained loudly
[19:50:42] <maddash> squeaky wheel gets oiled?
[19:51:00] <archivist> vent313, you have a lot to learn about realtime systems
[19:51:23] <vent313> maddash: so I shall be scared about overheating - as a first problem, right?
[19:51:29] <archivist> I got told off for moaning at Acorn!
[19:51:33] <maddash> vent313: overheating your laptop?
[19:51:43] <jepler> vent313: often things are more complicated than we first imagine. I often discover this when I scoff and say "I could do that myself in an afternoon". hopefully I learn from that experience..
[19:51:44] <maddash> vent313: overheating what?
[19:52:21] <vent313> archivist: i'm young and only 5 month in linux - head is reeling, already need some rest for all the info i've learnt
[19:52:27] <vent313> maddash: CPU
[19:52:29] <jepler> maddash: according to intel datasheets, if you disable the SMI you are running your CPU outside of its thermal specification
[19:52:50] <alex_joni> _if_ you disable SMI
[19:52:52] <jepler> maddash: but many people with intel CPUs find that they don't get adequate realtime performance when SMI is enabled
[19:52:55] <maddash> grep -rn memcpy *|less
[19:53:05] <maddash> q
[19:53:11] <vent313> jepler: i'm too - that's why i think about programming issues after some first-order skilled info
[19:53:11] <maddash> geez
[19:53:28] <alex_joni> jepler: another thing that just "hit" me.. there are about 10? sources that SMI can disable
[19:53:33] <alex_joni> I mean rtai_smi
[19:53:50] <alex_joni> we usually disable them all, but maybe only one or a few should be enough
[19:53:57] <vent313> alex_joni: how can i disable SMI? in BIOS??
[19:54:07] <alex_joni> vent313: it's a special module part of RTAI
[19:54:13] <alex_joni> you shouldn't worry with it
[19:54:16] <vent313> ok
[19:54:24] <maddash> jepler: i'm reenabling anyway
[19:54:27] <vent313> i will think about it later, not today
[19:54:41] <alex_joni> it's only needed if you want 100% realtime performance
[19:54:54] <alex_joni> if you only use your laptop for show-off, I wouldn't install it
[19:54:57] <motioncontrol> excuse another question.I have 3 axis.i want one axis not linear but angular axis.i modified in ini file at line type = angular .restart emc , but the axis not count 0-360 grad , but only linear increment because?
[19:55:35] <shrdlu-> oh, heh, I found the other sensor
[19:55:42] <shrdlu-> cunningly hidden
[19:55:57] <vent313> by the way, when i worked with FEM, i used to put the system blick of my PC on the window - in winter. this way CPU was cold withing 1-hour calculations at full speed. it was P4
[19:56:06] <vent313> *block*
[19:56:44] <shrdlu-> 'system block'?
[19:56:57] <vent313> i know this celeron has strange temperature 53 celsius degree
[19:57:20] <vent313> shrdlu-: i meant those box with hdd, motherboard, power supply
[19:58:39] <vent313> also, i know, kernel "wakes up" CPU rather more than MS W....... OS does. And CPU is hot in linux, in general. Can believe in failures on laptops with something being switched off... :(
[19:59:26] <motioncontrol> excuse another question.I have 3 axis.i want one axis not linear but angular axis.i modified in ini file at line type = angular .restart emc , but the axis not count 0-360 grad , but only linear increment because?
[19:59:51] <maddash> man memcpy
[19:59:51] <maddash> hell
[19:59:51] <maddash> * maddash is in love with MIPS32
[20:00:26] <micges> motioncontrol: xyz are always linear
[20:00:33] <micges> abc are angular
[20:01:13] <archivist> motioncontrol, make it the 4th axis A
[20:01:35] <motioncontrol> ok.thanks i thing the name axis is indipendent at declaration the type axis.thanks
[20:01:41] <jepler> motioncontrol: and emc never treats the angular axes as "wrapping around". If start at A0, turn clockwise 720 degrees and then command A0, it'll turn -720 degrees not 0 degrees.
[20:02:33] <jepler> many people expect different behavior, but this is what emc does
[20:02:43] <archivist> jepler I can see a case for that being changed one day
[20:02:58] <motioncontrol> excuse my english but i don't understand jepler
[20:03:18] <jepler> your english is fine, I'm struggling to express what I want to say.
[20:03:31] <motioncontrol> normaly angular axis move count start 0 fine 360
[20:03:42] <jepler> emc doesn't care whether A=0 A=360 A=720 and so on actually indicate the same orientation
[20:04:09] <jepler> if your gcode has made the rotary axis turn two full circles, then to go back to A0 it turns two full circles in the oppsite direction
[20:04:16] <motioncontrol> ok.but one turn the motor is 360 grad?
[20:04:47] <jepler> in gcode, you always command angles in degrees. A degree is 1/360 of a circle.
[20:04:49] <archivist> motioncontrol, yes if set correctly
[20:05:42] <motioncontrol> ok thanks for your patience
[20:07:13] <jepler> You said "grad" earlier, but to me "grad" is 1/400 of a circle.
[20:07:32] <archivist> jepler, when hobbing there will be thousands of revolutions and it needs to be stopped checked and set back to start position with a small offset and re run. A wind back wont be nice
[20:07:41] <jepler> archivist: yeah I know it sucks
[20:08:09] <archivist> I dont want to see a float error in the reset either :)
[20:08:54] <jepler> archivist: oh in emc 2.3 that problem will be licked -- or at least postponed by about 100 million times as many revolutions
[20:09:07] <archivist> I must look closely at the code jmk pointed out on the list earlier
[20:09:17] <jepler> archivist: which code is that?
[20:09:40] <archivist> the gearing between axis code
[20:09:42] <jepler> encoder_ratio? or something else?
[20:09:42] <jepler> ah
[20:10:28] <skunkworks_> because of doubles?
[20:10:31] <jepler> skunkworks_: yes
[20:10:33] <skunkworks_> nice
[20:10:41] <archivist> adding a helical offset in as well will be fun
[20:10:54] <archivist> differential gearing :)
[20:15:48] <steve_stallings> steve_stallings is now known as steves_logging
[20:17:12] <vent313> maddash: it asks for a file to patch, due to 2.6.25, not 2.6.24 'th kernel... what file to patch? ()
[20:17:54] <vent313> maddash: -p1 option only, right? I have written -p1 -b options, christ the lord...
[20:18:31] <maddash> vent313: erm, try -p1, -p0, -- trial and error.
[20:18:49] <vent313> --trial ??
[20:19:03] <vent313> i'm knew to the world of patches
[20:19:24] <vent313> it've asked for -R, i said "no, no way"
[20:20:08] <vent313> should i say "yes, darling" ;) Think it can help with female laptops ;)
[20:20:41] <maddash> vent313: no, no
[20:20:46] <vent313> Perhaps you used the wrong -p or --strip option?
[20:21:24] <maddash> vent313: I meant, try 'patch --dry-run -p[...] < ..." with different -p0, -p1, etc.
[20:21:37] <vent313> ok
[20:21:46] <maddash> vent313: the patch should apply cleanly
[20:21:56] <vent313> ok
[20:23:13] <vent313> but patch is 2.6.24, but my kernel is 2.6.25, can it bring up des problema, as french folks say?
[20:24:05] <vent313> ok, i think that my -b option has trashed this my system. will re-install it and see
[20:32:01] <vent313> ah, i have trashed kernel files, renewing it
[20:33:51] <alex_joni> * alex_joni is off to bed
[20:33:54] <alex_joni> good night all
[20:34:05] <BigJohnT> good night
[20:34:11] <vent313> alex_joni: good night and sweet dreams
[20:34:36] <vent313> ...with fried potato ant ketchup and... i want to eat
[20:38:07] <jepler> rtai folks say that you should only apply their patches to the exactly matching unmodified kernel
[20:38:15] <jepler> so 2.6.24 patch on 2.6.25 is "don't do that"
[20:38:53] <vent313> jepler: i pay 1 usd for 10 mb, have 2.6.25 on cd - don't want to download anything
[20:39:09] <vent313> ah and oh
[20:39:14] <jepler> I'm sorry my advice is inconvenient for you
[20:39:41] <maddash> erm, is there a '#else if' statement to check if a macro is defined?
[20:39:55] <vent313> can i download e.g. rtai-3.6.3, not rtai-3.6.2 ?? can i try to download the newest version then?
[20:39:57] <jepler> maddash: #if !defined(MACRONAME)
[20:40:01] <maddash> e.g., #ifdef XYZ ... #elifdef XYY ... #endif
[20:40:20] <maddash> jepler: so, #elif defined(XYZ)?
[20:40:46] <jepler> maddash: yes I believe that's right
[20:46:30] <vent313> maddash: Does p1 mean nice level = 1 ??
[20:47:54] <maddash> vent313: no, dude. p1 means to chop off the first directory prefix
[20:47:59] <maddash> vent313: man patch, dude.
[20:48:06] <vent313> ok
[20:49:38] <vent313> haven't understand "patch" is a standard command...
[20:52:27] <vent313> maddash: Hunk #1 FAILED at 316.
[20:53:18] <maddash> vent313: what command are you running? care to pastebin?
[20:53:42] <vent313> maddash: where to paste it? paste.org?
[20:53:55] <vent313> sudo patch --dry-run -p1 < /usr/src/rtai-3.6.2/base/arch/x86/patches/hal-linux-2.6.24-x86-2.0-07.patch
[20:54:17] <vent313> maddash: i'm applying it to 2.6.25 kernel
[20:54:36] <cradek> that's why it doesn't work
[20:54:41] <vent313> have no another kernel, only 2.4.36.
[20:55:05] <jepler> if the patch fails, then you have to figure out what's wrong and fix it. the linux kernel often changes quite radically from 2.6.x to 2.6.x+1, and that's one reason for the advice from rtai people that I gave you earlier.
[20:55:28] <maddash> vent313: and this is executed in /usr/src/linux-2.6.24 ?
[20:55:28] <maddash> vent313: if not, have you tried i386?
[20:55:37] <vent313> cradek: really? this can be a tough reason. It's ok then. I will do it later, with free internet access and proper kernel version
[20:55:53] <vent313> /usr/src/linux-2.6.25$
[20:56:13] <vent313> maddash: trying i 386
[20:58:09] <vent313> it's 2.6.23 and: Hunk #1 succeeded at 513 with fuzz 2 (offset 22 lines). can't find file to patch at input line 20 Perhaps you used the wrong -p or --strip option?
[20:58:42] <maddash> no, no
[20:58:53] <vent313> ok, will read doc/html these days and learn that first-order info I have told about.
[20:58:57] <maddash> hm, funny, no rtai for 2.6.25?
[20:59:05] <vent313> maddash: yes, yes, will read it
[20:59:17] <vent313> maddash: nope...
[20:59:23] <maddash> vent313: hold on -- have you tried both patches in base/arch/x86/patches?
[20:59:39] <maddash> vent313: i see a -05.patch and -07.patch
[20:59:51] <vent313> maddash: rtai-3.6.2 are ther a newer one? How can I browse their web-site?
[21:00:14] <maddash> vent313: huh? you downloaded -3.6.2 from the link I gave you, right?
[21:00:14] <vent313> maddash: no, actually plan some attempts
[21:00:20] <vent313> yes
[21:00:27] <maddash> christ. https://www.rtai.org/RTAI/
[21:01:02] <vent313> maddash: and there's rtai-3.6.1 into wiki
[21:01:23] <vent313> maddash: i think it's a web site, not a
[21:01:56] <vent313> ...not a Christ. But i can't be sure i have an error viewing it thru toonel.net 'proxy
[21:02:34] <vent313> though i would like to see Christ. turning off proxy and go again...
[21:04:14] <maddash> why are you using a proxy?
[21:04:40] <vent313> i pay 1 usd for 10 mb on my cell phone
[21:04:50] <maddash> so?
[21:05:00] <maddash> use a normal internet connection?
[21:05:09] <maddash> how would a proxy help?
[21:05:25] <vent313> i'm close to the mountain snowboard mecca here at russia. Cable internet is a big weird and non-really reliable and cheap yet
[21:05:53] <maddash> isn't alex_joni in russia also?
[21:05:57] <vent313> maddash: zlib compression with no images saves about 46-70%% of traffic
[21:06:52] <vent313> maddash: don't know, but he is rather at western russia
[21:06:59] <vent313> ..then
[21:07:15] <vent313> it's close to the morning right here
[21:07:48] <vent313> ok, i've confirmed exception and i'm on the site
[21:08:33] <maddash> vent313: so why the proxy?
[21:09:54] <vent313> maddash: for http, it saves 40% of $$ i pay, for anything really compressed, this proxy is actually an obstruction, and wget with -c option is a good native tool i'm using
[21:10:31] <vent313> maddash: do you mean https://www.rtai.org/RTAI/rtai-3.6.2-m68knommu.tar.bz2 as a solution?
[21:12:00] <maddash> vent313: which rtai version did you download?
[21:12:36] <vent313> ...and kernel-2.4.36 i have on cd will not support my laptop, i think
[21:12:39] <vent313> maddash: 3.6.2
[21:13:49] <vent313> weird. it is made after that '03.2008 cd, which contains kernel-2.6.25.tar.bz2
[21:15:10] <vent313> ah... will read ~/doc/html at first, ftw
[21:17:58] <maddash> vent313: I'll extract the patch files (which are only several hundred KB) for you so that you can test them
[21:18:36] <vent313> ok, thanks, e-mail it to love15411@gmail.com, please.
[21:21:55] <vent313> i'm also learning finnish language for fun. today, i've downloaded http://www.nationmaster.com/encyclopedia/Finnish-grammar (which is a big web page). Learning french verbs was hard, 've started to learn finnish for fun. ie.languages.org or so is good, too.
[21:23:56] <motioncontrol> the emc support spline conturing?
[21:24:45] <maddash> no.
[21:27:41] <motioncontrol> is possible in emc2.2.8 not load the initial scrren for select configuration and load the configuration in .ini file and open only the cnc axis interface?
[21:28:31] <vent313> motioncontrol: there were an article in en.wikipedia.org about this. So it uses a finite number of piecewise lines to "simulate" the spline, and cad -> cam program with it's settings is doing it. e.g. cam expert.
[21:29:32] <motioncontrol> ok thenks fo spline, in my cnc a load one bidimensional array data.www.flexmotioncnc.com
[21:29:59] <vent313> motioncontrol: if you know spanish, Portuguese, italian or french, i can give you legal licensed cam expert for you verification of its manual on one or more of these languages
[21:30:29] <maddash> http://www.adrive.com/public/975ff05f2adbd450efb8bce302d4a580a571fe77b5b73e53aa33c2da70e68a9f.html
[21:30:34] <vent313> motioncontrol: i can't follow this link today, already in minus on my cell phone account
[21:30:46] <maddash> vent313: ^ that's rtai 3.5 , 3.6 , 3.6.1, 3.6.2, etc.
[21:31:05] <vent313> maddash: what do you mean?
[21:31:12] <maddash> $ md5sum.exe rtai-3.5+3.6.1+3.6.2-m68knommu.tar.bz2 909fb4da6bff04af15b6e7a67ba7b24b *rtai-3.5+3.6.1+3.6.2-m68knommu.tar.bz2
[21:31:36] <vent313> ah...........
[21:31:37] <maddash> vent313: download and untar it, and see which patch would work
[21:31:45] <vent313> ok
[21:32:04] <maddash> so you don't have to download an entire rtai pkg only to find that it doens't patch cleanly
[21:32:29] <maddash> thank god for cygwin
[21:33:10] <maddash> vent313: oh, and move to hong kong, for god's sake
[21:33:19] <vent313> maddash: are you in windows?
[21:33:58] <vent313> why to hong kong? i'm not a king kong!
[21:37:51] <vent313> ah. 5.1 mb is too huge for today. I will do it tomorrow
[21:40:13] <vent313> ok, have to quit
[21:43:38] <motioncontrol> there is the people can send me the 5i22 file(hal,core,ini) in my mail for sutding and modification for my 5i20 card?
[21:44:07] <motioncontrol> i use old driver 5i20 card
[21:44:36] <motioncontrol> i want use the new hm2-pci driver
[21:46:19] <motioncontrol> my mail is amigalove@alice.it thanks
[22:16:40] <maddash> fucking sparkfun -- sent me two defective cameras consecutively
[22:38:31] <ds3> anyone tried using threaded inserts in acrylic?
[23:34:17] <maddash> help! transistors prefixed with 'C' are PNP or NPN?
[23:34:27] <maddash> vs. transistors prefixed with 'A' I mean
[23:39:10] <jepler> maddash: this looks relevant, but I can't vouch for it -- I just google'd.
