#emc | Logs for 2005-10-02

[00:07:05] <CIA-8> 03paul_c * 10documents/wiki/ (130 files in 2 dirs): Recovered data from wiki - Needs some tidy up..
[00:26:24] <alex_joni> this hurts http://www.riemurasia.net/jylppy/displayimage.php?album=11&pos=221
[00:28:20] <jmkasunich> what happened to the wiki?
[00:30:15] <Jymmm> robin took it offline after being put on a 24hr ban for trolling in #emc
[00:31:33] <Jymmm> (robin was hosting the wiki on his servers)
[00:31:41] <jmkasunich> I knew that
[00:31:45] <jmkasunich> nice of him that was
[00:31:56] <Jymmm> wikis are icky
[00:31:57] <icee> i just love people who throw temper tantrums and take their ball and go home.
[00:32:19] <alex_joni> * alex_joni is in posetion of the wiki ;)
[00:32:20] <Jymmm> icee Never heard it put so elegantly
[00:32:27] <cradek> don't be so quick to say that
[00:32:42] <alex_joni> cradek: can I mail you to put it online?
[00:32:50] <alex_joni> * alex_joni can't do that right now :/
[00:33:03] <alex_joni> set up the wiki that is
[00:33:06] <cradek> alex_joni: I'll try, but I make no promises
[00:33:17] <icee> lyle.org could host it too
[00:33:18] <Jymmm> icee mind if I quote you?
[00:33:24] <icee> jymmm: nope
[00:33:39] <alex_joni> who's lyle.org?
[00:33:40] <icee> lyle.org being my host; i've got 100mbit connectivity and decent system resources
[00:33:48] <alex_joni> ahh,, ok
[00:33:54] <alex_joni> can you set it up?
[00:34:00] <icee> I often forget at freenode I'm not mlyle@lyle.org
[00:34:07] <Jymmm> really needs a KB, not a wiki
[00:34:07] <icee> I can't now, because I'm about to go finish painting my garage
[00:34:11] <icee> but I could later today
[00:35:58] <icee> If you want to email me the wiki, i can create an account and vhost for it, and initially install it
[00:36:23] <icee> and then I can give account info to whoever wants to run it in the long term
[00:37:28] <alex_joni> icee: lets see if we can't get it running first
[00:37:34] <icee> OK.
[00:37:35] <alex_joni> if not, I'll mail you. ok?
[00:37:49] <icee> alex: Sure thing. If you want account info to run it here, just let me know and i'll set you up.
[00:38:12] <alex_joni> thx
[00:38:15] <Jymmm> icee In the meantime... I got 2PB (that's peta bytes) of p0rn you can host =)
[00:38:30] <icee> haha. I -do- have a 1200GB bandwidth quota per month
[00:38:33] <Jymmm> err QUALITY p0rn
[00:38:44] <icee> i'd be happy to host that pr0n here at home tho
[00:38:58] <icee> * icee sighs
[00:39:00] <Jymmm> icee Got NetworkAppliance?
[00:39:01] <alex_joni> icee: beware it's featuring Jymmm
[00:39:17] <icee> jymmm: I could put together a small SAN if it's good stuff ;)
[00:39:18] <icee> anyways
[00:39:22] <icee> off to paint. cya'll.
[00:39:22] <Jymmm> icee alex_joni wishes (damn pervert keeps starting at me in the shower)
[00:39:40] <alex_joni> later
[00:39:47] <alex_joni> Jymmm: that
[00:39:53] <alex_joni> that's your kid brother
[00:39:57] <alex_joni> bib
[00:40:05] <alex_joni> biab
[00:40:08] <Jymmm> alex_joni wth you blabbing about?
[01:07:08] <alex_joni> night guys
[01:08:01] <Jymmm> G'Night alex_joni
[01:11:35] <anna_emc> hello
[01:11:52] <alex_joni> buona notte anna_emc
[01:13:22] <anna_emc> night
[02:03:44] <CIA-8> 03paul_c * 10CVSROOT/cvsignore: Add a few more patterns to ignore.
[02:37:06] <CIA-8> 03paul_c * 10CVSROOT/loginfo: Reinstate commit message filtering - Don't want to flood emc-commit when cron jobs start on the wiki pages.
[09:11:55] <Jymmm> G'Night Folks!
[09:21:30] <ValarQ> godmorning folks
[11:20:17] <ValarQ> jmkasunich: ayt?
[14:53:18] <paul_c> paul_c has changed the topic to: Welcome to the Enhanced Machine Control forum - Support and development of a linux based CNC control. | Home page www.linuxcnc.org | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT | General linux discussions and support the rest of the week. | Final release BDI-4.30 | Six people have ops capabilities - Lucky dip ! | wiki up @ http://emc.sourceforge.net/cgi-bin/emcinfo.pl
[15:02:47] <zsteva> does exists simple way to rebuild emc on bdi-4.29 ? i'm changed kernel (no hdd dma in default config), and need to rebuild all modules
[15:03:15] <paul_c> there is a reason DMA isn't enabled
[16:40:31] <jmkasunich> jmkasunich is now known as jmk_away
[17:11:18] <jmk_away> hi dave
[17:11:47] <dave-e> hi jmk
[17:16:40] <dave-e> ok hi again jmk ... i was on the phone
[17:16:48] <jmk_away> s'ok
[17:17:05] <jmk_away> I'm about to leave anyway (visiting my parents, 2 hr drive)
[17:17:14] <dave-e> I understand you found the right taps on the mazak transformer to to 90 v dc.
[17:17:38] <jmk_away> well I think so (based on recollections from when we were there in june
[17:18:01] <dave-e> mine is not so flexible but i can get the dc voltage down to 112
[17:18:35] <jmk_away> hmm, I would have expected them to be the same
[17:19:16] <dave-e> well they look the same but mine only has the 190, 230 and 275 taps on the primary side
[17:19:27] <dave-e> and 90 and 18 on the secondary
[17:20:28] <dave-e> the 18 is used for phasing ref for the drives
[17:21:22] <dave-e> how difficult would it be to make either a zero crossing or phase-triggered scr's that actually regulate the filtered voltage to 90 vdc
[17:21:32] <jmk_away> you're feeding 240 into the 275 tap?
[17:21:38] <dave-e> yes
[17:21:58] <jmk_away> fairly complicated to do it from scratch
[17:22:05] <jmk_away> I dunno if something could be adapted
[17:22:19] <jmk_away> are you feeding 3-phase, or single phase?
[17:22:49] <dave-e> three phase into xformer and three phase to a bridge
[17:23:39] <dave-e> if one were really stubborn then the old drives are simple power supplies. ;-)
[17:23:41] <jmk_away> a trick that can be used to get different voltages out of the xfmr is to reconnect either primary or secondary from wye to delta configuration (or vice-versa, depending on what you have to start with)
[17:24:22] <dave-e> hmmm... would that cause problems with my phase converter
[17:24:36] <jmk_away> depends
[17:24:48] <jmk_away> but probably not
[17:25:33] <jmk_away> if you had a real neutral (real 3-phase source), then 240V L-L also means you have 138V L-N
[17:26:02] <dave-e> actually the 11 kw transformer on the back may be inbtween
[17:26:17] <jmk_away> if the primary is delta, then each primary winding is intended for 190/230/275V
[17:26:33] <jmk_away> connecting them in wye means you could for example feed the 190 taps with 138
[17:26:39] <dave-e> don't know if Ive ever checked leg to gnd
[17:27:08] <jmk_away> actually, that might be exactly what we figured out in June
[17:27:43] <dave-e> could be but then you have real 3 ph to play with
[17:27:51] <jmk_away> if the primaries are delta, and can be reconnected as wye, then use the 190V taps, feed with 240V L-L (no need for a neutral as long as the load is balanced) and you get 92VDC
[17:28:08] <dave-e> perfect
[17:28:28] <dave-e> I'll do some checking
[17:28:33] <steves_logging> steves_logging is now known as steve_stallings
[17:28:34] <jmk_away> there might be some harmonic issues if neither primary or secondary is delta
[17:28:53] <dave-e> but then I get to filter that anyway
[17:29:07] <jmk_away> if you can figure out a winding diagram for your transformers, I can look at it and consider other options
[17:29:22] <dave-e> ok..I'll take a look
[17:29:24] <steve_stallings> also be careful about transformer core saturation, if your actions put greater than expected voltage across a primary winding and saturation results, current goes to infinity
[17:29:43] <dave-e> opps
[17:29:46] <jmk_away> things needed: primary winding config (wye or delta), primary taps, and whether it is physically practical to reconfigure it, also secondary configuration
[17:29:55] <dave-e> can do
[17:30:09] <jmk_away> steve: aware of that, all options that I would consider would run less flux than nominal
[17:30:31] <steve_stallings> k
[17:30:34] <jmk_away> we're trying to reduce the 90V AC output so that it can be rectified to make ~90V DC
[17:30:46] <dave-e> I'll try and find the appropriate page and copy
[17:30:58] <jmk_away> changing from phase-controlled drives to choppers
[17:31:13] <jmk_away> ok, gotta go now...
[17:31:19] <jmk_away> jmk_away is now known as jmk_away_logging
[17:31:22] <dave-e> this gives me something to work on
[17:31:29] <dave-e> enjoy your visit
[17:31:36] <jmk_away_logging> thanks
[17:36:05] <paul_c> Yo steve_stallings
[17:36:21] <steve_stallings> Yo
[17:36:37] <paul_c> didya get the second note ?
[17:37:02] <steve_stallings> yes, didn't know you could run cgi and perl on sourceforge
[17:37:27] <paul_c> There is much that you can do at SF
[17:38:10] <steve_stallings> there seems to be some stuff missing from wiki, did you recreate it from some archive?
[17:38:33] <paul_c> What is missing ?
[17:39:03] <steve_stallings> cannot remember all, but there were intructions on wiki usage and how to log on
[17:39:59] <paul_c> http://emc.sourceforge.net/cgi-bin/emcinfo.pl?BasicSteps ?
[17:41:58] <steve_stallings> OK, didn
[17:42:19] <steve_stallings> OK, didn't remember page was re-organized, had not seen in a few weeks
[17:43:21] <steve_stallings> Paul, your last topic change shows an incomplete url on my IRC client
[17:43:55] <paul_c> * paul_c hands steve_stallings a copy of Ksirc
[17:45:36] <paul_c> paul_c has changed the topic to: Welcome to the Enhanced Machine Control forum - Support and development of a linux based CNC control. | Home page www.linuxcnc.org | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT | wiki up @ http://emc.sourceforge.net/cgi-bin/emcinfo.pl | Six people have ops capabilities - Lucky dip !
[17:45:43] <paul_c> howzat ?
[17:46:11] <steve_stallings> better, link is clickable now
[17:46:42] <paul_c> * paul_c installs a dos prompt
[17:48:37] <steve_stallings> wiki index of pages seems to have gotten broken
[17:50:03] <paul_c> Can you set up the DNS record for wiki.linuxcnc.org to point to the SF url ?
[17:50:45] <steve_stallings> planning to set all links and DNS, was just testing stuff first
[17:55:12] <paul_c> Index was a simple wiki edit
[17:58:03] <paul_c> When SF is back up to 100% service, I'll show you where stuff is located, and then you can take over the maintenance & backups of the web space.
[17:58:49] <steve_stallings> CNAME record for wiki.linuxcnc.org now set on primary DNS, hope it works, I have never set at CNAME with a file path included
[17:59:27] <paul_c> how long does it take to filter down to the other DNS servers ?
[18:01:11] <steve_stallings> TTL (time to live) of this record is 24 hours
[18:01:46] <steve_stallings> link on linuxcnc.org web page is now updated
[18:02:05] <steve_stallings> it was done direct to sourceforge for now
[18:05:04] <paul_c> When the DNS records get updated, I'll let you edit the /topic
[18:11:26] <steve_stallings> Paul, it appears that file paths do not work in CNAMEs or ALAISs
[18:15:48] <steve_stallings> if the CNAME includes a path it does not resolve
[18:16:41] <steve_stallings> I have temporarily set CNAME to just emc.sourceforge.net and this brings up some sample or test wiki not related to emc
[18:16:41] <paul_c> let's see what apache.org says on the subject
[18:18:26] <paul_c> damit - SF has a wiki running already.
[18:23:04] <steve_stallings> and this surprises you?
[18:25:05] <steve_stallings> is it possible for you to create a pseudo machine at wiki.emc.sourceforge.net?
[18:28:18] <paul_c> might be able to do something with htaccess
[18:28:53] <paul_c> or even index.php
[18:30:04] <steve_stallings> well I can preset CNAME to whatever you think will be useful and let it propogate
[18:31:04] <paul_c> Just point it to emc.sourceforge.net - Worse case, it will redirect to www.linuxcnc.org
[18:31:55] <steve_stallings> no, that is where it points now and the test/sample wiki for Sourceforge comes up
[18:32:26] <paul_c> Go to http://emc.sourceforge.net
[18:33:59] <paul_c> Pinging wiki.linuxcnc.og doesn't return a SF server.
[18:34:18] <paul_c> Don't think the DNS record has propogated yet.
[18:34:39] <steve_stallings> no it has not, I am testing on local machine that get DNS from primary
[18:39:42] <paul_c> Would suggest waiting for a few hours.
[18:51:42] <steve_stallings> Paul, it looks like Sourceforge is doing some kind of mapping. If I put the emc.sourceforge.net URL into a browser it hits your new page and works. If it gets there by CNAME redirection results differ based on URL that was redirected.
[18:52:07] <steve_stallings> wiki.linuxcnc.org and test.linuxcnc.org resolve to the same IP but get different results
[18:52:44] <steve_stallings> test.linuxcnc.org goes to an empty directory listing, wiki.linuxcnc.org still hits the sample wiki
[18:52:48] <paul_c> Edited index.php @ SF to redirect to the cgi-bin script
[18:53:25] <paul_c> So, fingers crossed, when the cname record updates, it should work fine.
[18:53:54] <steve_stallings> no, I am testing on a local machine that can ONLY see master DNS, doesn't need propogation
[18:54:32] <steve_stallings> you should be able to try test.linuxcnc.org since it is a fresh record with no history in DNS servers
[18:55:12] <steve_stallings> we can repeat the test with new test2.linuxcnc.org etc.
[18:55:28] <paul_c> does the url resolve to ?
[18:56:35] <steve_stallings> both resolve to (projects.sourceforge.net) but get different treatment by server
[18:57:16] <paul_c> OK.. We need to log a support request to get them to update the vhost configs then.
[18:58:04] <paul_c> wiki.linuxcnc.org is now resolving to the SF IP...
[18:58:28] <steve_stallings> OK, I will leave CNAME for wiki.linuxcnc.org set to emc.sourceforge.net
[19:00:03] <steve_stallings> the test.linuxcnc.org CNAME will be let set to same place so you can use it for differential testing in case Sourceforge is using referrer URL to route stuff
[19:04:58] <paul_c> \o/ admin interface for setting vhost
[19:05:21] <paul_c> May take up to six hours for the records to update at SF
[19:07:13] <steve_stallings> OK, catch you later...
[19:07:20] <paul_c> 'k
[19:07:27] <steve_stallings> steve_stallings is now known as steves_logging
[19:17:24] <alex_joni> hello
[19:21:26] <alex_joni> awfully quiet for a sunday
[19:26:09] <steves_logging> steves_logging is now known as steve_stallings
[19:26:16] <steve_stallings> Hi Alex
[19:26:30] <alex_joni> hey steve
[19:26:39] <alex_joni> noticed the new status message?
[19:27:06] <alex_joni> especially: | wiki up @ http://emc.sourceforge.net/cgi-bin/emcinfo.pl |
[19:27:11] <steve_stallings> Yes, Paul seems to have captured a version of the wiki and gotten it running directly on the Sourceforge
[19:27:22] <alex_joni> yeah.. I sent him the wiki I got from robin
[19:27:27] <alex_joni> and I just mailed it to you too
[19:27:28] <steve_stallings> Not sure if it has all the latest or not
[19:27:35] <steve_stallings> OK
[19:27:38] <alex_joni> it is the latest
[19:28:30] <steve_stallings> Paul and I have been trying to get the www.linuxcnc.org URL to work. Seems we have to wait several hours for a vhost command at Sourceforge to take effect.
[19:28:45] <alex_joni> you just need to register your username again
[19:43:51] <rcsu> hi all
[19:44:16] <rcsu> is there a test proggie to test a stepper card on the parallel port ?
[19:44:35] <alex_joni> what kind of test proggie?
[19:45:04] <rcsu> just set some bits, kinda basic things
[19:45:30] <alex_joni> there's a tcl script
[19:45:40] <alex_joni> start tkemc, and then you have a parport test thingie
[19:45:44] <alex_joni> * alex_joni can't recall the name
[20:02:50] <steve_stallings> steve_stallings is now known as steves_logging
[20:06:23] <rcsu> thanks alex_joni
[20:07:35] <alex_joni> np
[20:23:43] <seanMc> Hello everyone
[20:23:51] <alex_joni> hello
[20:24:08] <ValarQ> hi
[20:24:45] <seanMc> new to EMC
[20:25:20] <seanMc> I built my own router and am trying to learn how to use it
[20:26:21] <ValarQ> router?
[20:26:29] <seanMc> ? is there any apps that can convert dxf files to g code for linux out there that are free
[20:26:39] <seanMc> a cnc router
[20:26:48] <ValarQ> ok
[20:27:26] <alex_joni> seanMc: some
[20:27:35] <alex_joni> there's Ace (simple dxf->gcode)
[20:28:34] <alex_joni> but you might want to check www.timeguy.com too
[20:28:42] <alex_joni> there is some autocad script iirc
[20:29:36] <seanMc> ok I'm checking out those sites right now
[20:33:18] <seanMc> Thank you very much I'll try a couple of his programs
[20:33:28] <alex_joni> coo..
[20:33:33] <alex_joni> you can thank him personally if it works
[20:33:41] <alex_joni> * alex_joni points seanMc to cradek
[20:33:47] <cradek> * cradek waves
[20:42:27] <seanMc> hi
[21:04:59] <rayh> alex_joni: Hey what's happening
[21:05:17] <alex_joni> not much
[21:05:20] <alex_joni> learning :/
[21:05:50] <rayh> you young guys can still do that.
[21:06:09] <alex_joni> well.. I wouldn't .. if I had a choice :)
[21:06:17] <alex_joni> but I got some exams these days :((
[21:06:26] <rayh> what you studying?
[21:08:18] <rayh> has paul_c been round these parts today?
[21:08:26] <alex_joni> was yesterday night
[21:08:49] <alex_joni> re studying: finishing my IWE degree
[21:09:58] <rayh> I never got past the bs welding stage. Everything I tried broke apart.
[21:10:05] <alex_joni> heh
[21:11:39] <rayh> Have we got any clues why bdi-4.29 won't boot properly?
[21:11:51] <alex_joni> no idea
[21:11:56] <alex_joni> but htere is 4.30 out now
[21:13:15] <rayh> I thought I had the last stuff when I added in the latest deb sources but I lost it all today and it will not reboot.
[21:13:41] <rayh> something in grub get's gnarled up.
[21:56:06] <Jymmm> boo
[22:01:32] <ValarQ> what? where?
[22:02:30] <Jymmm> at the Monster MAsh
[22:02:39] <Jymmm> it's a graveyard smash!
[22:03:07] <anna_emc> hello
[22:03:14] <alex_joni> parked your car wrong Jymmm ?
[22:03:29] <anna_emc> alex_joni jacky?
[22:04:02] <Jymmm> alex_joni Have you been sniffing the solvent the last couple of days or something?
[22:06:04] <alex_joni> Jymmm: similar
[22:16:06] <alex_joni> * alex_joni goes back to learning
[22:16:14] <alex_joni> Jymmm: too much information lately
[22:16:35] <alex_joni> gotta make room for that, so the bad part of the data has to go ;)
[22:16:47] <alex_joni> that should explain what you've seen these days :P
[22:21:16] <Jymmm> Uh huh.... I still think it's the solvent
[22:25:27] <alex_joni> probably
[22:32:41] <Jymmm> what are you learning that's it's turning your brain to jello?
[22:40:12] <ValarQ> jello? where? what?
[22:43:42] <Jymmm> PARROT! Where? There --> ValarQ <--- Dumbass says's WHAT?
[22:53:52] <Jymmm> (couldn't resist the temptation)
[23:05:34] <anna_emc> night
[23:05:39] <anna_emc> night
[23:07:09] <alex_joni> Jymmm: IWW
[23:07:10] <alex_joni> IWE
[23:07:17] <alex_joni> darn.. can't type abbr.
[23:51:32] <alex_joni> steves_logging: seems there's a bad vname for the wiki
[23:51:36] <alex_joni> steves_logging: seems there's a bad vname for the wiki
[23:51:49] <alex_joni> it points to some other wiki
[23:51:56] <alex_joni> not to emc.sourceforge.net
[23:52:22] <alex_joni> yup. it seems to be pointing to wiki.sourceforge.net (as in the sf wiki)
[23:57:15] <steves_logging> steves_logging is now known as steve_stallings
[23:58:18] <steve_stallings> Alex, yes, problems at Sourceforge, Paul is trying to resolve. There is a valid link to the wiki on the Linuxcnc.org page that bypasses the DNS issues.
[23:58:34] <alex_joni> okie
[23:58:40] <alex_joni> just pointed it out
