[00:21:37] <jmkasunich> who makes the best allen wrenches?
[00:22:09] <jmkasunich> I have some mother effin tight small screws (2.5 and 4mm wrenches) and I'm twisting wrenches
[00:30:25] <JymmmEMC> jmkasunich: snap on
[00:30:49] <jmkasunich> thanks - now I just need to find some
[00:31:01] <JymmmEMC> have you tried boudhouse
[00:31:04] <JymmmEMC> bondhaus
[00:31:14] <JymmmEMC> I've had my set for years
[00:31:32] <jmkasunich> no, all I have on hand at the moment is crapsman
[00:31:37] <JymmmEMC> ah
[00:31:47] <JymmmEMC> Actually sears might seel bondhaus
[00:31:57] <jmkasunich> my inch set are Elkund (or something like that, good ones), but the metrics, dunno
[00:32:22] <jmkasunich> when I think of Bondhaus, I think of ball end, which would _not_ work here - the ball would snap off
[00:32:59] <JymmmEMC> they make micro tools for jewerly and electronics... not one .ca screw I can't remove using them
[00:33:05] <JymmmEMC> .cn
[00:33:15] <jmkasunich> .cn?
[00:33:32] <jmkasunich> china?
[00:33:59] <JymmmEMC> yeah
[00:34:06] <jmkasunich> these ain't china setsecrews
[00:34:22] <JymmmEMC> they have the oddest heads and usually get stripped the most
[00:34:29] <jmkasunich> they're in what I sure was a very expensive machine tool spindle
[00:34:47] <jmkasunich> I'm not stripping the head, I'm twisting the shank of the allen-wrench
[00:35:00] <JymmmEMC> I undestand
[00:35:17] <jmkasunich> it doesn't help that the screw is 2" down a hole, and I have to use the long end of the wrench in the screw
[00:35:35] <JymmmEMC> I'm just syaing that they make the end of the tool actualyl fit the head so that doens't occure
[00:37:39] <JymmmEMC> how large is the opening?
[00:37:42] <JymmmEMC> opening
[00:39:07] <JymmmEMC> jmkasunich: what about something like this...
http://www.quinntoolsonline.com/catalog/TH-412S.jpg
[00:39:30] <JymmmEMC> then use a ratchet extension
[00:40:02] <JymmmEMC> and an impact wrench =)
[00:42:50] <jmkasunich> that might work
[00:43:09] <jmkasunich> but I need a 4mm blade that can get down a hole about 1-1/2" deep and maybe 3/8" diameter
[00:43:38] <jmkasunich> right now I'm trying to figure out how to apply a bit of heat - I think they used locktite, and heat should soften it
[00:44:09] <JymmmEMC> toss a lil debatured alcohol doen the hole and light a match
[00:44:14] <JymmmEMC> denatured
[00:44:39] <JymmmEMC> burns with a white flame, so be careful - almost invisable
[00:48:12] <JymmmEMC> http://en.wikipedia.org/wiki/Denatured_alcohol#Uses
[00:49:58] <JymmmEMC> interesting use for sanding wood
[00:51:36] <jmkasunich> got one out
[00:51:46] <jmkasunich> a soldering iron fit nicely down the hole
[00:51:49] <JymmmEMC> woohoo
[00:51:53] <JymmmEMC> heh
[00:51:57] <jmkasunich> it was coated with locktite
[00:53:03] <JymmmEMC> what are you crackign open?
[00:53:11] <jmkasunich> disassembling some spindles
[00:53:16] <JymmmEMC> ah
[00:55:19] <jmkasunich> speaking of cracking, how is the safe?
[00:59:01] <JymmmEMC> I've be helping someone doing some hdd recovery so havent' been on it. But I called the mfg and they faxed over the manual.
[00:59:17] <JymmmEMC> I need to pinout the PCB to see what they're doing.
[00:59:58] <JymmmEMC> But at least I now know that there is NOT a button inside the safe, all programming is done on the ouside, so I still need to figure out why there are three wires going into the safe.
[01:00:18] <JymmmEMC> One is common to GND, not sure about the other two
[01:01:19] <JymmmEMC> They're using an Atmel uC and a EEPROM
[01:02:02] <JymmmEMC> both are off the shelf components
[01:04:58] <JymmmEMC> Those assholes!
[01:05:50] <JymmmEMC> I look at the footer of the fax I got in, says I can now change my prerences to receive PDF's. okey cool. Goto my account, and if I want DPf I have to pay a monthly fee.
[01:06:48] <JymmmEMC> No thanks, I'll stick with the fee account tyvm - I don't recv faxes that often
[01:06:55] <JymmmEMC> s/fee/free/
[01:57:18] <DrStein99> hi is anyone in here?
[02:23:14] <cradek> woo, I changed tools
[02:23:32] <cradek> and I have most of the estop chain and most of the limits/homes
[02:29:18] <jepler> cradek: cooooollll
[02:29:24] <jepler> sounds like lots of progress for one weekend
[02:29:29] <cradek> yes very much so
[02:29:47] <jepler> you still don't have the resolver-to-encoder boards right?
[02:29:55] <jepler> "comma right"
[02:29:57] <cradek> right, no motion for a while
[02:30:07] <cradek> plenty of other stuff to do though.
[02:30:51] <cradek> there are four signals coming from the turret position sensor - one doesn't do anything
[02:31:13] <cradek> but it only needs three, so maybe it's on purpose. I haven't deciphered the pattern yet.
[02:54:55] <jtr> cradek: you mentioned running a coolant pump from single-phase. I cobbled together a static phase converter and idler motor a while back.
[02:55:33] <cradek> jtr: I currently have a big rotary converter, but I hope to get everything running on single phase to avoid the noise and complexity
[02:56:54] <cradek> hm, .5 HP new vfd is $110...
[02:57:03] <jtr> The idler is 1 HP, two terminls to the two legs of the power line, 35 UF run cap between one leg and the third terminal. nothing else. so you may be able to run your coolant pump with a single cap.
[02:57:24] <jtr> starts in less than a second.
[02:59:38] <cradek> woo, that sure sounds simple.
[02:59:55] <cradek> does it always start (and always in the same direction?)
[03:00:18] <cradek> my phase convert has a small 1ph starter motor, so no caps
[03:00:52] <cradek> I just looked - this motor is marked 1/6 HP.
[03:01:44] <jtr> yes and yes. I had plans to do it up nice with extra balancing caps and a start circuit, but it works too well to bother with. Maybe when I get the mill hooked up...
[03:02:42] <cradek> is it a small mill? 1hp idler motor sounds pretty small. mine is 8hp.
[03:06:20] <jtr> The lathe it was built for has a 1/2 hp motor; the mill will probably need a better setup, but I don't remember the size offhand.
[03:06:45] <cradek> http://www.metalwebnews.com/howto/ph-conv/fig1.html
[03:07:24] <cradek> they show an extra cap for starting only... I haven't found a diagram of run-cap only
[03:09:30] <jtr> I had thought I might have to kick-start until I got the better setup, but it fired right off.
[03:10:47] <cradek> aha, "self starting method" sounds like what you have
[03:13:21] <jtr> I was going to use these plans eventually:
http://www.metalworking.com/dropbox/_1998_retired_files/FRW-n.txt
[03:15:26] <jtr> Fitch helped a number of people tune them on rec.crafts.metalworking
[03:15:47] <cradek> neat. I will read
[03:15:56] <cradek> thanks for the pointers, I'm encouraged to try it
[03:18:42] <jtr> welcome - and with Surplus Center nearby, caps shouldn't be expensive.
[03:19:13] <cradek> yep
[03:22:09] <mozmck> I built a rotary phase converter with an old three phase motor for an idler and some caps and a potential relay
[03:22:47] <mozmck> and a magnetic starter.
[03:23:19] <mozmck> it starts with a push button and when it gets up to speed the starting cap drops out.
[03:23:38] <mozmck> if you're interested I can dig up the articles I used to build it...
[03:24:28] <cradek> thanks but I think I'm set. I'm browsing run caps now...
[03:24:47] <cradek> jtr: how many MFD per HP do you have on yours? I see numbers from 30-50
[03:26:05] <jtr> the Carlson article mentions 70 UF/HP starting cap - I'm actually using 35 to start and run the unloaded idler. So maybe 6UF for the 1/6 HP, but it won't be completely unloaded, so you might go up a little.
[03:27:25] <cradek> I will get 5, 6, 7.5 - they are very cheap
[03:27:34] <cradek> sounds like one of them should balance it ok.
[03:28:41] <jtr> I used a clamp-on ammeter to check the currents in the three leads to the motor, and measured the voltages across the windings to see that I wasn't generating real high voltages.
[03:29:34] <cradek> I don't have one of those ammeters, but I will check the voltages and should be able to pick the best cap value
[03:29:48] <cradek> http://surpluscenter.com/item.asp?UID=2008081022193269&item=11-3201
[03:29:55] <cradek> these sure look nice
[03:33:41] <jtr> Of course, I was "tuning" with the lathe running as a load. That is a nice switch - you thinking for the E-stop chain?
[03:34:15] <cradek> yes I need to put one or two on it
[03:42:36] <jtr> Sounds like you've made great progress tonight. Good luck, and take pictures! The cats have all gone to bed, so i guess it's time for me, too. Good night.
[03:42:44] <cradek> goodnight

[14:15:22] <jepler> hi stustev1
[14:24:15] <stustev1> good morning
[14:24:42] <stustev1> I think this may be my first time in the room this early
[14:25:13] <stustev1> I saw some of you guys were on early and not as much later
[14:25:24] <stustev1> I will try it for a while at work
[14:25:33] <jepler> that's where I am right now
[14:26:09] <stustev1> I figured that - maybe the responses will be slow as work interferes?

[17:19:57] <mr_jimjames> Hello
[17:20:23] <mr_jimjames> I have a pinout question for the stg and the hal
[17:20:51] <mr_jimjames> does hal label the pins different from the stg card's manual?
[17:21:52] <mr_jimjames> i cannot get the emc out of estop.
[17:27:19] <BigJohnT> what is stg?
[17:27:36] <mr_jimjames> servo to go
[17:27:51] <mr_jimjames> http://www.servotogo.com/dwnld/hardman2.pdf
[17:27:52] <BigJohnT> ok, out of my guesspertice level
[17:28:06] <mr_jimjames> ok
[17:28:42] <mr_jimjames> how about a different question
[17:29:00] <BigJohnT> ok
[17:29:02] <mr_jimjames> i can get the machine to activate my relays by hitting estop
[17:29:03] <mr_jimjames> but
[17:29:18] <mr_jimjames> the estop button doesn't come out of estop
[17:29:22] <anonimasu> what's a i733? (just kidding)
[17:30:51] <BigJohnT> are you using the axis interface?
[17:31:09] <mr_jimjames> i use mini, but tried tkemc too.
[17:31:22] <mr_jimjames> i could try axis
[17:32:06] <BigJohnT> anyway you might have the estop input on or off as the case might be
[17:32:43] <BigJohnT> I think that would prevent you from changing the state of the e stop button in axis
[17:32:58] <mr_jimjames> ok,
[17:33:08] <BigJohnT> I've never used mini or tkemc...
[17:33:31] <mr_jimjames> are you talking about the hal file, or the actual pins?
[17:34:20] <BigJohnT> well if you have the e stop pin configured in your hal file and don't have the input hooked up it might act like you describe.
[17:34:38] <mr_jimjames> ok
[17:35:12] <BigJohnT> I'm not on a linux computer so I can't look and see but if you pastebin your hal file perhaps someone can spot it
[17:35:31] <mr_jimjames> ok.
[17:35:41] <mr_jimjames> i don't have it on me right now.
[17:36:26] <BigJohnT> are you using one of the sample configs that came with EMC?
[17:36:39] <mr_jimjames> yes
[17:36:53] <mr_jimjames> it said in 12 ... out 7
[17:37:19] <BigJohnT> what did?
[17:37:24] <mr_jimjames> the hal file
[17:37:39] <mr_jimjames> i think i have it connected wrong.
[17:38:02] <BigJohnT> I would ask which config but I can't look at them AFAIK from here
[17:38:20] <mr_jimjames> ok
[17:39:44] <BigJohnT> actually I can look, what config are you using?
[17:39:54] <mr_jimjames> stg_io.hal
[17:40:49] <BigJohnT> what version of EMC?
[17:41:02] <mr_jimjames> the new umbuto with emc2 i believe
[17:45:45] <BigJohnT> one moment customer on phone
[17:46:08] <mr_jimjames> no problem
[17:48:48] <BigJohnT> there is a section that starts out connect e-stop... If you don't have your e-stop wired up yet you will have to comment out the lines indicated
[17:49:50] <mr_jimjames> I have a transistor/relay setup to connect the machine to the computer using +5v from the card.
[17:50:05] <mr_jimjames> in my last install i used the estop button to do this.
[17:50:37] <mr_jimjames> i am guessing i don't have the right pins connected.
[17:50:58] <mr_jimjames> i should be on pin 12 and 7?
[17:53:13] <mr_jimjames> page 12 connector p1
http://www.servotogo.com/dwnld/hardman2.pdf
[17:53:24] <mr_jimjames> i don't think that is labeled the same.
[17:53:26] <BigJohnT> kinda looks like the e stop is connected to 12 and 7 is connected to the pc
[17:53:46] <BigJohnT> I've never seen a stg so I'm guessing a bit
[17:54:03] <mr_jimjames> connected to the pc?
[17:54:23] <BigJohnT> I have to leave now, perhaps someone can answer your question better
[17:54:32] <mr_jimjames> ok, thanks
[17:54:37] <BigJohnT> sorry
[18:09:21] <luca> c'è qualcuno che parla italiano?
[18:09:25] <robin> so, let me see .. pid tuning ..
[18:09:40] <robin> if FERROR is 1.0 (mm) ....
[18:10:05] <robin> then, P must be a MINIMUM of 10?
[18:10:50] <robin> otherwise it will never get to +10 on Aout?
[18:11:25] <robin> mine seem to oscillate like anyting with a P term over 5
[18:11:52] <robin> I was hoping to tighten up FERROR ... but that would impl a larger P term no?
[18:12:05] <luca> c'è qualcuno che parla italiano?
[18:12:23] <fragalot> luca: no.
[18:13:09] <fragalot> luca: Provi a parlare inglese (babelfish translation, don't hurt me)
[18:16:08] <luca> I can?
[18:17:19] <luca> excused if I write badly, use a translator babelfish
[18:17:40] <luca> I wanted to have information on the compensation g41/42
[18:19:33] <jepler> luca: here are some links:
http://linuxcnc.org/docs/html/gcode_main.html#sub:G40,-G41,-G42: http://linuxcnc.org/docs/html/gcode_main.html#sec:Cutter-Radius-Compensation
[18:20:40] <jepler> because of the "concave corner" limitation (9.4.1.7 in that link), it is generally not possible to make CAM software generate code that works with emc's G41/G42. However, it can be useful for hand code when you add appropriate arcs on all corners
[18:23:18] <luca> I have not understood well as an example here, in order to make a square
[18:23:30] <luca> g0x2y2
[18:23:52] <luca> No
[18:24:15] <luca> g0x0y0
[18:24:33] <luca> g1g41 d2 x2 y2
[18:24:42] <luca> g1x2y10
[18:24:55] <luca> g1x12y10
[18:25:32] <luca> why it cannot be compensated?
[18:26:37] <luca> you can makes me an example of compensation for a foreign working and an inner one of a square? thanks
[18:32:30] <luca> good bye

[19:53:08] <alex_joni> micges: hi
[19:53:21] <alex_joni> 16:29 < cradek> micges: as far as we know, the problem you reported was fixed
[19:53:21] <alex_joni> in 2.2.6. Are you sure you have the problem on 2.2.6 like your
[19:53:21] <alex_joni> report says?
[19:53:36] <alex_joni> * alex_joni heads to bed
[19:53:39] <alex_joni> good night all
[19:55:11] <micges> thanks alex
[20:02:44] <micges> cradek: I've installed 2.2.6 from update manager
[20:03:23] <micges> that pretty sure that command "emc" in console launch 2.2.6
[20:03:46] <micges> and then I made those two tests
[20:31:52] <Roguish> hey guys, got a weird error after some regular updating. any ideas what i screwed up?
[20:31:56] <Roguish> [25183.753824] rtapi: no version for "nano2count" found: kernel tainted.
[20:31:58] <Roguish> [25184.148047] motmod: Unknown symbol sincos

[20:33:08] <Roguish> 2.6.24-16-rtai (#1 Sun Apr 13 17:50:16 EEST 2008)
[20:33:11] <SWPLinux> if you installed from normal Ubuntu then added EMC2+the RT kernel, then any normal kernel updates will set themselves to boot
[20:33:13] <SWPLinux> hmmm
[20:33:21] <SWPLinux> well, maybe it's something else then :)
[20:34:28] <Roguish> i'm trying to be really careful with all this updating stuff.
[20:34:34] <SWPLinux> good plan
[20:37:28] <jepler> this one is my fault, and it looks like I forgot to fix it on CVS TRUNK when I did in the v2_2_branch: [25184.148047] motmod: Unknown symbol sincos
[20:37:52] <SWPLinux> nano2count is surprising though, that's a kernel symbol
[20:37:56] <SWPLinux> or it should be
[20:38:09] <SWPLinux> oh, is that RTAI?
[20:40:04] <SWPLinux> oops - gotta run
[20:41:54] <Roguish> sorry, had a phone call myself.
[20:42:07] <jymm> oh man, missed him by that much
[20:42:41] <jepler> Roguish: a CVS up should fix the 'sincos' error now, and the other is just a warning
[20:42:59] <Roguish> ok, thanks.
[20:43:26] <Roguish> heck, i even got my script working to do the update!!!!
[20:55:22] <tomp> BigJohnT: I looked into luca's question & stumbled on a paper by Kramer ( one of the fathers of EMC ) on milling bores
http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=6805026FD5756DF4F8E0D24A5336A711?doi=10.1.1.31.231&rep=rep1&type=pdf
[20:55:23] <tomp> it reminded me of your wizards.
[21:06:35] <skunkworks_> this is awesome. (not done by me)
http://fantasticcontraption.com/?designId=192073
[21:06:53] <tomp> regarding luca's question, i do not know if emc's interpreter can compensate discontinuous/'not-smooth' paths
[21:06:59] <tomp> (where subsequent gcode moves are non tangential)
[21:07:00] <tomp> this would require foreshortening the 'inside square' and automatically adding radii to the 'outside square'
[21:15:15] <robin_sz> so, I set some values in PID based onthe ziegler-nichols suggestions ...
[21:15:30] <robin_sz> and it tracks ok, but sounds sort of ... mmm .. rough
[21:15:34] <robin_sz> like running on sand
[21:20:47] <jepler> hm I could have sworn the wiki had a page on jon elson's interactive tuning procedure .. having tried Z-N and automatic tuning before I've never seen them give really good tuning, but Elson has a pretty good step-by-step procedure that he's demoed multiple times at CNC workshop
[21:21:38] <jepler> I think his is more or less the "simple method" described here:
http://linuxcnc.org/docs/html/motion_pid_theory.html#r1_1_3
[21:21:46] <jepler> though a big part of his presentation is showing *how* to do this in halscope
[21:23:13] <jepler> well I give up -- I can't find the wiki page
[21:32:18] <robin_sz> ok, I'll look
[21:32:36] <robin_sz> i looked in the integrators manual, was expectign to see some procedure involving halscope
[21:32:44] <robin_sz> but, it didnt mention it
[21:33:33] <robin_sz> yep, thats Z-N,
[21:34:30] <robin_sz> I was hoping to see some small description of how to hook up halscope to read Aout and then spply impulses and whatch the response
[21:35:15] <skunkworks_> one last one.. then I am done.. this one I did.
http://fantasticcontraption.com/?designId=363142
[21:43:18] <tomp> heh, jon's vs ZN: they have the same start point, then Jon's is art & ZN is formula. I was taught Jon's. I bet most old-school servo tuners use it too.
[22:13:53] <robin_sz> ah well
[22:14:05] <robin_sz> I guess I'll just hook a real scope up and play
[22:14:54] <robin_sz> i have some neat baldor drives that tune themselves
[22:15:05] <robin_sz> whether its optimal or not I dont know
[22:20:35] <jepler> http://emergent.unpy.net/index.cgi-files/sandbox/axis-calibration.png
[22:21:06] <jepler> get the calibration menu with Machine > Calibration and halscope with Machine > Hal Scope
[22:21:22] <jepler> choose at least 2 channels and servo-thread
[22:21:29] <robin_sz> hmm
[22:21:33] <robin_sz> I only have one channel
[22:21:46] <jepler> in halscope you get up to 16 :-P
[22:22:05] <robin_sz> oh I hought you menat axes
[22:22:07] <jepler> "position" is used mostly for triggering
[22:22:13] <robin_sz> ok
[22:22:35] <jepler> so for channel 1 select the position command -- for me it's signal Xpos-cmd and I think that's typical of sample configurations in emc
[22:22:52] <jepler> click the "1" button, then click "signals" and scroll to find Xpos-cmd or something else that looks plausible
[22:23:26] <jepler> or you can choose the PID input signal, pid.0.command, which should be the same thing
[22:23:35] <jepler> then click "2", click "pin", and choose pid.0.error
[22:23:46] <robin_sz> ah, ok
[22:24:13] <jepler> now go into machine on and mdi a move, then click "force" in halscope to make it capture
[22:24:31] <jepler> (you might have to click 'normal' under 'run mode' first)
[22:24:39] <robin_sz> * robin_sz scribbles all this down
[22:24:56] <jepler> once you've done this, you can click the "1" or "2" label again, then use the "gain" and "pos" sliders to position and scale the trace you selected
[22:25:35] <jepler> then to set a trigger, you're going to click where my screenshot says "source chan 1", and select channel 1 (position)
[22:25:36] <robin_sz> P seems to be about 4
[22:25:45] <robin_sz> I is around 2
[22:25:51] <robin_sz> D around 0.075
[22:26:26] <jepler> then you can move the "level" slider so that it is in the middle of the move that you are going to use for testing -- I was using "g0 x0" and then "g0 x1" to move 1 inch each time
[22:26:40] <jepler> once you've done that you can repeatedly mdi G0X0 / G0X1 and you'll get a fresh trace whenever you G0X1
[22:26:51] <robin_sz> * robin_sz nods
[22:27:56] <robin_sz> I'll go and have a go
[22:28:08] <jepler> so in the calibration window here's what you do:
[22:28:44] <jepler> type in proposed values for P, I, D and so on. Click "test". Then do your test move G0X0/G0X1 and decide if it's better or worse. If it's better (i.e., you want to keep it) click "ok"
[22:28:53] <robin_sz> uh huh
[22:28:54] <jepler> if it's worse (i.e., you want your prior numbers back) click "cancel"
[22:29:13] <robin_sz> k
[22:30:15] <jepler> when you're done, you can in principle click "save to file" though personally I'd jot down the numbers and edit my inifile by hand. otherwise the values you found will be lost when you restart emc
[22:30:25] <robin_sz> * robin_sz nods
[22:30:30] <robin_sz> ok, off to try
[22:30:35] <robin_sz> thanks for the help
[22:30:38] <robin_sz> and the fish
[22:30:39] <jepler> have fun
[22:30:44] <robin_sz> :)
[22:31:56] <jepler> oh and it might also be useful to select 3 channels and make pid.0.output be one of them
[22:32:14] <jepler> (actually you have to select 4 channels in that case)
[22:32:21] <jepler> then you can see stuff like the DAC saturating at +10V
[22:42:42] <dmess> hi all
[22:42:47] <jepler> hi dmess
[22:43:14] <dmess> hey Jep... can you help with a restoration of a system at all??
[22:43:32] <jepler> what's the trouble?
[22:44:44] <dmess> i blew the power supply.. ( thought it was the battery - replaced it ) and MO-BO and HD dont like each other GRUB 21 error
[22:45:24] <dmess> replaced the p/s too
[22:46:13] <jepler> same mobo and hard drive as before the trouble?
[22:46:33] <jepler> or you mean you replaced the mobo because of the battery (soldered battery?)
[22:49:24] <jepler> I would try following these instructions:
http://ubuntuforums.org/showthread.php?t=224351
[22:50:23] <dmess> same mobo and drive.. i replaced the battery on the mobo
[22:52:28] <dmess> " probing .... this may take a log time"
[22:52:55] <jepler> maybe you had made some changes in the bios -- boot order, enable/disable ide ports?
[22:53:04] <jepler> changing cmos battery shouldn't affect the bootloader
[22:53:14] <jepler> but if there's a bios setting that the bootloader was depending on
[22:53:15] <jepler> ...
[22:56:02] <dmess> that looked like it might have worked... gimme a few reboots and i'll be back
[22:57:32] <jepler> some recommended feeds/speeds for working in FR4 with small drills -- don't think I'll be going at 200krpm or 125inch/minute anytime soon, though:
http://www.kyoceratycom.com/pdfs/200K_FS_FR4_Multilayer_High_Tg_Multiple_CLs.pdf
[22:58:33] <jepler> it's interesting that the chip load curve they found is not linear, but more S-shaped
[22:58:46] <jepler> (what's "max hits"?)
[22:59:07] <jepler> hi pminmo
[22:59:15] <pminmo> hi jepler
[22:59:24] <pminmo> new problem.....:-(
[22:59:40] <pminmo> know anything about rtai errors
[22:59:55] <jepler> can you be more specific?
[23:01:04] <pminmo> yes, I need to put up the dump on pastebin, but I did an install on another computer of mine it won't initialize rtai
[23:02:16] <pminmo> http://pastebin.com/m9b844dc
[23:03:58] <pminmo> jepler were you at the cncfest this year?
[23:04:30] <jepler> pminmo: yes I was
[23:04:41] <pminmo> did I meet you?
[23:04:48] <jepler> I don't think so
[23:05:01] <jepler> but I met so many people and I'm lousy at remembering so it's entirely possible
[23:05:16] <pminmo> I understand, I have the same problem
[23:05:42] <pminmo> I'll remember RayH because of the classes
[23:06:12] <jepler> in your log I notice that before you had the problem with rtai, the kernel had already encountered a problem with the sound driver saa7134_alsa (around line 344 of your paste, 85 seconds after boot)
[23:07:16] <jepler> this suggests a couple of things -- maybe the machine is just flaky. run memtest on it or boot the official ubuntu CD (not the emc2 ubuntu CD) and see if sound works there.
[23:07:37] <jepler> or maybe the version of the saa7134_alsa driver that got packaged with emc is buggy
[23:07:55] <JymmmEMC> Gawd, I swear I'm gonna kill the insurance companies!
[23:08:02] <jepler> in that case you can add the line "blacklist saa7134_alsa" to the file /etc/modprobe.d/blacklist with a text editor and try restarting
[23:08:25] <pminmo> interesting, it had the previous version of Ubuntu and EMC and runs winxp about every other day
[23:09:14] <pminmo> could a bad cd cause this?
[23:10:57] <jepler> I don't know -- you could run the media check from the cd boot menu to try to eliminate that possibility
[23:12:22] <dmess> hey Jepler.. can you drop me that site again
[23:12:38] <jepler> 17:49:24 <jepler> I would try following these instructions:
http://ubuntuforums.org/showthread.php?t=224351
[23:13:52] <dmess> thx... i think i foun a defective drive...
[23:14:46] <jepler> well heck
[23:15:32] <pminmo> how did you relate line 344 to the saa7134_also driver ?
[23:16:47] <jepler> pminmo: line 344..378 is all from one error
[23:17:22] <jepler> I guess the saa... driver because it's mentioned on line 377 as containing the actual instruction that caused the error

[23:17:50] <dmess> down for another try
[23:17:55] <dmess> see ya
[23:17:56] <pminmo> I really don't need sound I could disable in the bios
[23:18:01] <jepler> well that might work too
[23:18:18] <pminmo> anything else you notice as a problem
[23:19:10] <jepler> well there's the error message printed when rtai fails but I don't see anything useful there
[23:20:18] <pminmo> i also tried to do latency testing but it wouldn't initialize either
[23:20:26] <pminmo> rati i mean
[23:20:50] <pminmo> and both situations leave my keyboard non responsive
[23:25:33] <jepler> shoot, I don't have any other ideas offhand
[23:25:36] <jepler> and life is calling .. bbl
[23:26:12] <pminmo> thanks
[23:28:07] <JymmmEMC> what device are you having issues with?
[23:38:23] <pminmo> jepler thinks saa7134_alsa sound driver
[23:38:56] <pminmo> i just tried disabling in the bios which didn't help so I'm going to try to blacklist it
[23:39:54] <JymmmEMC> what is saa7134?
[23:40:27] <pminmo> well I was just doing a google search as I thought it was my onboard sound but its not
[23:40:46] <pminmo> its a tv card that is plugged in but I don't use, so I'll pull it
[23:41:17] <JymmmEMC> It's probably confliciting with the base address of another on-board device.
[23:41:19] <pminmo> back in a few minutes
[23:56:46] <pminmo> blacklisting the saa7134 did the trick...........:-)
