[00:38:19] <lilo> [Global Notice] Hi all. We're experiencing server issues....there may be some server recycles needed. Please bear with us.
[00:52:44] <lilo> [Global Notice] Hi all. Our problems are a little less broad than we've thought.... affected users, about 7,000, and we should be stable. We're removing one server from the main rotation and we've shut it down. Apologies for any inconvenience. If there are no more high-impact problems, any further messages will be on wallops.

[13:30:26] <Imperator_> Hi all
[13:30:50] <alex_joni> hi Martin
[13:30:58] <alex_joni> frohe weihnachten
[13:31:13] <Imperator_> Hallo alex
[13:31:23] <Imperator_> W�nsch Dir auch frohe Weihnachten !!!
[13:31:37] <Imperator_> hast Du wei�e Weihnachten
[13:32:13] <alex_joni> ziemlich weiss... ich weiss nicht ob es noch lange anh�lt, ist schon beim schmelzen ;)
[13:32:38] <Imperator_> hier ist es schon weg, aber morgen soll es kalt werden und schneien
[13:33:12] <Imperator_> anybody here with FPGA knowledge ??
[13:33:27] <Imperator_> back to english :-)
[13:35:02] <Imperator_> in the german forum was somebody asking how to get emc2 running with steppers
[13:35:35] <alex_joni> oh man.. this guy has a problem:
http://www.lewrockwell.com/barnwell/barnwell53.html
[13:35:36] <Imperator_> has something changed there ??
[13:35:45] <alex_joni> Imperator_: the run script, and the configs
[13:36:01] <alex_joni> I'm off to look over that (cncecke?)
[13:36:12] <Imperator_> jep
[13:39:05] <alex_joni> seems you answered most of it
[13:39:12] <alex_joni> for anything else I would need further info..
[13:39:29] <alex_joni> btw, emc2 is starting by default with sim
[13:39:35] <alex_joni> and lately with the new config chooser
[13:41:21] <Imperator_> ah so he has to change the config
[13:41:48] <Imperator_> my emc2 version is a bit old
[13:42:21] <Imperator_> i thry to get my hardware working so it is better for me not to update emc
[13:42:38] <alex_joni> probably, although you could use a different folder
[13:43:06] <Imperator_> right, but i have enough to do with that :-)
[14:18:14] <alex_joni> * alex_joni is gone ...
[14:18:14] <alex_joni> later
[16:06:11] <robin_sz> Happy Christmas :)
[16:07:04] <robin_sz> ready for your xmas puzzle?
[16:07:20] <robin_sz> Three tourists stay in a motel, the motel keeper tells them it is $30 a night for the room, so they each pay $10. After they have gone to the room, he reallises he has made a mistake, it is only $25, so he sends the bellboy down with $5. Unable to dived $5 between 3 people, he gives each guest $1 and keeps $2 for himself.
[16:07:32] <robin_sz> So the guests have paid $9 each .. 3x $9 = $27, plus the $2 the bellboy has kept makes $29 .. where did the other dollar go??
[16:13:59] <cradek> robin_sz: that's silly
[16:19:37] <cradek> but happy christmas anyway
[16:29:58] <robin_sz> :)
[16:30:10] <robin_sz> had my wife puzzzled for 10 minute s:)
[16:33:06] <anonimasu> hey
[16:46:58] <skunkworks> hope everyone is having a great holiday
[16:47:19] <cradek> my holiday so far has involved getting out of bed and showering
[16:48:19] <skunkworks> ;)
[16:48:27] <skunkworks> your fix works
[16:48:37] <skunkworks> did I tell you that already?
[16:48:46] <cradek> great
[16:49:32] <cradek> I did test it a bit, but not on a real machine
[16:50:52] <cradek> the real test will be on a rotary axis where the accels are different by a factor of 10-100
[16:51:56] <cradek> it will still not be real great for coordinated linear/rotary moves
[16:52:32] <cradek> but I think I fixed all the trivial cases, which is better than nothing
[16:52:45] <skunkworks> great - don't you have a rotory axis?
[16:53:06] <cradek> I do, but when I made my new stepper drivers, I only made 3
[16:54:32] <skunkworks> ah - when you get a chance could you do a g0 move and then estop it (f1). The few times I did this I could not restart the machine. (second I turned the machine on I get following errors.) A version of this problem was fixed on the bug list.
[16:54:58] <cradek> does it do the same thing if you hit ESC instead of F1?
[16:56:04] <skunkworks> no - the escape deaccellerates to a stop - non panic.
[16:56:13] <skunkworks> and doesn't turn the machine off
[16:56:25] <cradek> ok that's what I expected
[16:56:37] <cradek> I think estop stops without decel
[16:56:43] <skunkworks> that is what I hear
[16:56:49] <cradek> when you turn back on, the remainder (decel portion) of that move is still queued
[16:56:54] <skunkworks> -clunk- ;)
[16:57:04] <cradek> so it tries to perform it without the leading accel, causing the following error
[16:57:39] <cradek> which bug dealt with this?
[16:57:47] <cradek> I'm not seeing it
[16:58:08] <skunkworks> finding it now
[16:58:30] <cradek> 1238801
[16:58:30] <skunkworks> http://sourceforge.net/tracker/index.php?func=detail&aid=1238801&group_id=6744&atid=106744
[16:58:55] <cradek> ok, I suspect that's a different problem
[16:59:01] <cradek> even though it had the same symptom
[16:59:28] <cradek> fwiw, I don't know what's supposed to happen at ESTOP (whether it should decel)
[16:59:40] <cradek> I think emc1 decels but I'm not sure without testing
[16:59:56] <cradek> obviously the current behavior is a bug, but I don't know what the right behavior is
[17:00:29] <cradek> I know some big machines use external braking (electrical or mechanical) for estop
[17:01:03] <cradek> this bug is probably one jmk should look at
[17:03:11] <skunkworks> ok - sounds good.
[17:03:52] <cradek> I think you should file a bug report
[17:03:57] <skunkworks> I would think the estop should stop the motion as fast as it can. (I really like the escape for abort where it deaccellerates) no lost steps
[17:04:17] <skunkworks> Can do
[17:04:21] <cradek> thanks
[17:05:42] <cradek> skunkworks: put it in the Motion Controller category so it gets assigned to him :-)
[17:06:31] <skunkworks> ok
[17:17:50] <skunkworks> http://sourceforge.net/tracker/index.php?func=detail&aid=1390123&group_id=6744&atid=106744
[17:21:30] <skunkworks> cradek - what is your next clock project. You have had some pretty neet ideas.
[18:18:57] <alex_joni> greetings
[18:22:16] <skunkworks> alex - happy holidays
[18:22:27] <alex_joni> thanks a lot, same to you
[18:23:09] <skunkworks> family get-togather later today. having taco salid right now ;)
[18:23:49] <alex_joni> enjoy..
[18:43:58] <robin_sz> * robin_sz notes that cradek observes different tradtitions to over here
[18:45:06] <alex_joni> hi robin
[18:45:14] <robin_sz> greetz
[18:45:22] <robin_sz> Bonne Fete!
[18:45:36] <alex_joni> greetz :)
[18:45:45] <alex_joni> got everything you hoped for? :D
[18:45:54] <robin_sz> ummm ... i guess.
[18:46:00] <robin_sz> I got a day off :)
[18:46:06] <alex_joni> that's nice
[18:46:40] <robin_sz> and a DVD of one of my favourite books that got made into a film
[18:46:54] <alex_joni> wot's that?
[18:47:05] <skunkworks> yah- what book?
[18:47:09] <robin_sz> "Touching the void" by Joe Simpson
[18:47:57] <alex_joni> hrmm.. don't know it
[18:48:05] <robin_sz> I have yet to find anyone who has managed to put it down once they started it
[18:48:37] <alex_joni> heh.. nice
[18:48:40] <robin_sz> so if you find a copy, set asside 4 hours before you open it :)
[18:49:36] <robin_sz> OK Christmas Dinner ... back later
[21:46:06] <cradek> robin_sz: what do you mean?
[22:21:36] <Jacky^afk> Jacky^afk is now known as Jacky^
[22:23:17] <Jacky^> hi alll :)
[22:25:01] <robin_sz> cradek: by different traditions I meant apparently you get up and shower on Christmas Day, over here we shower on New Years Day, every year, whether we need it or not.
[23:02:08] <cradek> yes, my people are a little strange
[23:16:07] <cradek> hi alex
[23:16:16] <alex_joni> hey chris
[23:16:25] <cradek> happy morning-after-christmas, if you celebrated it
[23:16:28] <alex_joni> Bonne fete!
[23:16:47] <alex_joni> yeah, we did.. how about yourself?
[23:16:53] <Imperator_> Alex that germany guy forgot to connect ground signal .-)
[23:16:57] <Imperator_> :-)
[23:17:05] <cradek> a little - I try to celebrate holidays as little as possible...
[23:17:11] <cradek> I think I'm a grinch
[23:17:18] <alex_joni> the grinch is sweet :)
[23:17:28] <alex_joni> Imperator_: that figures :D
[23:17:36] <cradek> mostly I'm not christian so the christian holidays mean little to me
[23:17:47] <cradek> but I understand that they are meaningful to others
[23:18:46] <alex_joni> I see.. other religion?
[23:18:55] <cradek> me? nah
[23:19:23] <alex_joni> ok, I'm not the religious guy myself..
[23:19:37] <alex_joni> but I guess I never bothered to give it much thought
[23:20:52] <K4ts> hello
[23:21:00] <alex_joni> anyways.. love the new camera :D
[23:21:07] <alex_joni> it's fast, and smart, and great
[23:21:10] <cradek> alex_joni: cool
[23:21:17] <alex_joni> I shot about 1 Gig in 2 days :(
[23:21:25] <Imperator_> what typ is it Alex
[23:21:30] <alex_joni> and that's jpeg, not RAW
[23:21:32] <cradek> alex_joni:
http://emergent.unpythonic.net/index.cgi/01135394085
[23:21:35] <alex_joni> Imperator_: eos 350D
[23:21:42] <Imperator_> so you need a bigger HD next
[23:21:43] <alex_joni> cradek: the sound stuff? jeff showed me that
[23:21:50] <cradek> ah, yeah
[23:21:52] <Imperator_> ups, thats nice
[23:21:55] <alex_joni> Imperator_: a bit problematic on the laptop
[23:22:08] <Imperator_> have a Pro 1
[23:22:11] <robin_sz> alex_joni: i take the view that while they are stuffing into the un-knowing minds of children as young as 4 in schools, I'll not worry about taking the piss out of the followers of the magic sky-pixie at every available opportunity
[23:22:43] <alex_joni> robin_sz: say again in english please ;)
[23:22:47] <cradek> robin_sz: I prefer to think of him as the magic sky-bully
[23:22:59] <cradek> robin_sz: but I'm too polite to say so :-)
[23:23:03] <Imperator_> which lens do you have
[23:24:51] <robin_sz> alex_joni: typing difficult too much alcohol
[23:25:08] <Jacky^> :D
[23:25:09] <cradek> alex_joni: robin_sz says he's also not christian
[23:25:16] <cradek> * cradek summarizes
[23:25:23] <alex_joni> Imperator_: the kitt one 18-55 and a 75-300 I bought separately
[23:25:37] <Imperator_> thats realy nice
[23:25:40] <alex_joni> yet both are pretty basic, no USM or IS
[23:25:54] <alex_joni> cradek: thanks, that's what I kinda figured too
[23:26:01] <Imperator_> since i have my Pro 1 i whish to have a SLR :-)
[23:26:16] <alex_joni> * alex_joni doesn't know the Pro 1
[23:26:23] <alex_joni> but the 350D is .. wonderfull
[23:26:29] <alex_joni> switch on, and shoot
[23:26:30] <Imperator_> canon Powershot Pro 1
[23:26:49] <alex_joni> don't have to wait for it to load, or read the card or whatever
[23:26:56] <alex_joni> about 0.2s turn-on time
[23:27:03] <Imperator_> jep
[23:27:10] <alex_joni> and finally some smart people on the menus
[23:27:12] <cradek> alex_joni: I still can't run emc2 without sudo
[23:27:18] <cradek> alex_joni: if you don't want to talk about it now, just say so
[23:27:31] <alex_joni> doesn't matter in which menu you are, if you want to take a pic push the trigger..
[23:27:34] <alex_joni> cradek: why not?
[23:27:40] <alex_joni> let's talk..
[23:27:47] <cradek> open failed: Permission denied
[23:27:47] <cradek> RTAPI: ERROR: Could not open shared memory area
[23:27:47] <cradek> HAL: ERROR: rtapi init failed
[23:27:48] <alex_joni> I'm still pretty fresh :D
[23:28:02] <cradek> ok
[23:28:14] <alex_joni> ok.. seems rtapi doesn't have root privileges
[23:28:17] <alex_joni> strange..
[23:28:36] <alex_joni> with sudo it works?
[23:28:37] <cradek> after it fails, it leaves a bunch of modules loaded when it exits
[23:28:39] <cradek> yes
[23:28:53] <alex_joni> strange.. can you run -v -d and send me the output?
[23:33:57] <alex_joni> ok, io is failing
[23:34:04] <alex_joni> try adding a sudo in front of it..
[23:34:18] <alex_joni> although I can't see why it would need root access to access HAL
[23:35:33] <cradek> open failed: Permission denied
[23:35:33] <cradek> RTAPI: ERROR: Could not open shared memory area
[23:35:33] <cradek> HAL: ERROR: rtapi init failed
[23:35:33] <cradek> halcmd: hal_init() failed
[23:35:33] <cradek> NOTE: 'rtapi' kernel module must be loaded
[23:35:35] <alex_joni> likewise all HAL acceses need to be root
[23:35:36] <cradek> Version: 1.1
[23:35:37] <alex_joni> that's bad..
[23:35:38] <cradek> Machine: EMC-HAL-SIM
[23:35:41] <cradek> open failed: Permission denied
[23:35:44] <cradek> RTAPI: ERROR: Could not open shared memory area
[23:35:46] <cradek> usrmotintf: ERROR: rtapi init failed
[23:36:42] <alex_joni> it seems to me that all HAL-related stuff needs to be sudo
[23:36:49] <alex_joni> although over here it works as a user too
[23:37:27] <cradek> seems I'm the only one with this problem, so it's probably a rtlinux thing
[23:37:29] <alex_joni> that's the reason why it unloads, because on unloading it does a 'halcmd show comp' to check for HAL components
[23:37:34] <alex_joni> and tries to rmmod them
[23:37:37] <alex_joni> I think so..
[23:38:05] <alex_joni> might be the user-side SHM access
[23:38:15] <alex_joni> probably it can't be accessed only as root
[23:38:55] <alex_joni> the quick fix would be to place sudo all over the runscript.. but I don't like that
[23:39:04] <alex_joni> I see no reason in running various parts as root..
[23:39:23] <alex_joni> cradek: is jef around?
[23:39:27] <alex_joni> s/jef/jeff/
[23:39:32] <cradek> alex_joni: haven't heard from him today
[23:39:38] <alex_joni> ok
[23:39:54] <alex_joni> so.. guess you'll have to add a few more sudo's on your runscript
[23:40:08] <alex_joni> if any other complain, I'll think about doing that in the CVS runscript too
[23:40:23] <alex_joni> but till then I think we shouldn't
[23:40:33] <cradek> fine with me
[23:41:05] <alex_joni> did you try a recent CVS?
[23:41:12] <cradek> yes, I just upped
[23:41:14] <alex_joni> * alex_joni hasn't the last few days :(
[23:41:23] <alex_joni> does the config picker pop up?
[23:41:38] <cradek> well I guess I didn't recompile
[23:41:43] <cradek> I'll do it
[23:42:15] <alex_joni> shouldn't need to
[23:42:19] <alex_joni> it's tcl
[23:42:34] <alex_joni> ahh.. probably didn't run src/config.status
[23:42:35] <cradek> have to run configure to change scripts/emc
[23:42:39] <alex_joni> to get the new runscript
[23:42:46] <alex_joni> config.status is a lot faster
[23:42:59] <cradek> well I have to compile now anyway; I did make clean
[23:43:04] <alex_joni> it's basicly reapplying the stuff configure already figured..
[23:43:20] <alex_joni> so you won't wait on the find /usr/src ;)
[23:45:09] <cradek> yes I got the configger
[23:47:29] <alex_joni> okie
[23:49:06] <cradek> wow when I run with MAX_ACCEL on x,y=20 and z=.2 I get some wildly wrong results from the TP
[23:49:18] <alex_joni> ouch
[23:49:33] <cradek> (now that we have per-axis accel)
[23:49:59] <alex_joni> right
[23:51:20] <cradek> it's easy to see on Chips's feet
