[11:47:30] <Lerneaen_Hydra> what's happening?
[12:04:25] <anonimasu> not much
[12:04:34] <anonimasu> eating breakfast then making parts
[12:45:57] <Lerneaen_Hydra> hopefully not at the same time
[12:46:50] <Lerneaen_Hydra> * Lerneaen_Hydra imagines a bowl of yoghurt&cereal next to a mill machining steel and using lots of cooltant, with lots of chips and coolant flying into the cereal
[12:46:52] <Lerneaen_Hydra> yummy
[13:42:51] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[14:47:27] <Lerneaen_Hydra_> ooh, I've found an app thats really fun to mess around with
[14:48:11] <Lerneaen_Hydra_> it does a FFT conversion and displays a waterfall-esqe freq/time image with intensity controlling brightness

[14:50:59] <alindeman> [Global Notice] Hi all. You may have noticed that services is currently offline. We're working to restore it quickly; however, if its downtime necessitates assistance, please feel free to contact me or any other on-duty staffer ( /stats p ). Thanks again.
[14:57:07] <etla> hi
[14:58:15] <Lerneaen_Hydra_> 'lo
[14:58:33] <etla> do you know if HEAD is broken ?
[14:59:25] <etla> my HEAD crashes with: Traceback (most recent call last):
[14:59:26] <etla> File "/home/etla/emc2.head/bin/axis", line 2678, in ?
[14:59:26] <etla> root_window.tk.eval("${pane_top}.jogspeed.s set [setval $jog_speed $max_speed]")
[14:59:26] <etla> _tkinter.TclError: wrong # args: should be "setval vel"
[15:01:01] <etla> could it be that I am running Ubuntu 5.1 ?
[15:01:10] <etla> A problem with the python version ?
[15:05:05] <jepler> setval is a function inside axis. In share/axis/tcl/axis.tcl rev 1.4, it was changed to accept two arguments.
http://cvs.linuxcnc.org/cvs/emc2/share/axis/tcl/axis.tcl.diff?r1=1.3;r2=1.4
[15:06:23] <jepler> you might see that error if you did not get a complete update, for instance by running "cvs up" inside the src/ directory instead of the top directory
[15:09:15] <etla> jepler: ok I'll try another cvs up
[15:09:51] <etla> I get lot's of "cvs update: move away `share/axis/tcl/support.tcl'; it is in the way
[15:09:51] <etla> " lines
[15:10:44] <etla> each line is followed by "C share/axis/tcl/support.tcl
[15:10:46] <etla> ". what does that mean ?
[15:12:49] <etla> ok, I did 'rm -R share' and 'rm -R lib', now cvs up runs cleanly
[15:44:09] <skunkworks> if the r is r - then it has in index pulse according to the pdf
[15:44:13] <skunkworks> oops
[15:44:55] <alindeman> [Global Notice] Hi all! Services should be back up and running. If you notice any issues, please contact an on-duty staffer ( /stats p )
[15:46:37] <etla> how do I enable halui in the ini ?
[15:46:48] <etla> I know I've done it before but just cant remember...
[15:48:28] <alex_joni> HALUI = halui
[15:48:33] <alex_joni> in the [HAL] section
[15:49:00] <etla> thanks
[15:49:04] <alex_joni> np
[15:49:11] <etla> I'm doing a writeup of my jogwheel adventures
[15:52:54] <skunkworks> Cool.. All this information helps :)
[15:53:22] <etla> huh? it will take a while... it'l go into my blog
[15:53:36] <etla> but it could be copied to the emc wiki or the manual if someone wants to do that
[15:58:11] <etla> is there a match8 component ?
[15:58:33] <etla> I have some older HAL files that use blocks match8, but how is it done in pre2.1 ?
[15:58:50] <alex_joni> loadrt match8
[15:58:57] <alex_joni> although blocks is still there
[15:59:06] <alex_joni> you'll just get an warning message
[15:59:47] <etla> oh, it's the new way of specifying how many... I tried match8=1, but apparently its match8 count=1
[15:59:58] <alex_joni> yes
[16:00:06] <alex_joni> man match8 :)
[16:00:25] <alex_joni> http://www.linuxcnc.org/docs/devel/html/man/man9/match8.9.html
[16:04:44] <etla> OK, now my jogwheel is working again !
[16:13:16] <alex_joni> yay
[16:13:42] <anonimasu> nice
[16:14:25] <alex_joni> etla: got pics?
[16:16:56] <etla> alex: yeah, but it will take a while to get them on the blog, figure a couple of hours (need to get home etc.)
[16:17:58] <alex_joni> * alex_joni can wait :)
[16:21:54] <etla> don't expect to much bling when it comes to the hardware, I've assembled the jogwheel and a couple of switches myself into an aluminium enclosure
[16:27:11] <skunkworks> cradek - how many line encoder is on your spindle?
[16:27:55] <cradek> I think both lathes I've worked on have 1024 line
[16:28:25] <alex_joni> so 4096 counts..
[16:28:24] <cradek> on my servo lathe I divide that by 8 I think so there are 512 counts/rev
[16:30:44] <cradek> setp encoder.2.position-scale 256
[16:30:49] <cradek> it must be /16
[16:33:48] <etla> why are there no coolant and spindle check-boxes in AXIS sim ?
[16:34:09] <cradek> those now go away if the proper hal signal is not connected to anything
[16:34:26] <cradek> the idea is that uselss stuff shouldn't clutter up the screen
[16:34:35] <etla> so if I connect them to a dummy signal I will get them back
[16:34:39] <cradek> yes
[16:34:42] <etla> good
[16:46:40] <skunkworks> cradek: thanks. we just got a cool 360 line incoder with index.
[16:47:13] <cradek> cool
[16:56:13] <cradek> are you working on a lathe now too?
[16:56:25] <skunkworks> no - just aquireing parts ;)
[16:56:52] <skunkworks> can't have too much stuff
[16:56:56] <cradek> of course not
[16:57:09] <cradek> especially hollow shaft encoders for spindles
[17:00:18] <skunkworks> does the index pulse have to be a certain way (like while both a/b are high) or doesn't it matter?
[17:01:33] <etla> I would guess it depends on what hardware you have
[17:02:54] <owhite> * owhite hangs with #emc crew wihile cutting on dee ol' laser.
[17:03:05] <cradek> I know it doesn't matter to the encoder module
[17:03:06] <owhite> dont talk a lot or you'll slow down my machine, okay?
[17:03:22] <skunkworks> ok - thanks
[17:03:52] <skunkworks> owhite: pretty cool huh? I surf while cutting :)
[17:04:00] <owhite> it is most fun.
[17:04:38] <owhite> by the way people:
http://www.nilno.com/100_0344.jpg
[17:05:23] <skunkworks> cute :) how many watts again?
[17:06:05] <owhite> 100. but the literature describes something called "developable power" and Coherent claims it has 250 watts of developable power.
[17:07:01] <cradek> is that Al?
[17:07:38] <owhite> its stainless. Aluminum is harder to cut.
[17:07:55] <alex_joni> cradek: al steals heat
[17:07:55] <skunkworks> what is it? CO2?
[17:07:55] <etla> is there any documentation for the new comps HAL stuff ?
[17:08:05] <owhite> CO2.
[17:08:10] <alex_joni> etla:
http://www.linuxcnc.org/docs/devel/html/
[17:08:34] <etla> we are just getting a 4W YAG from Coherent at work ;)
[17:08:54] <owhite> so nice.
[17:08:55] <alex_joni> 4W?
[17:08:58] <cradek> what's the kerf? it looks tiny
[17:09:03] <etla> 4 Watts
[17:09:09] <alex_joni> is that a laser pointer? <rimshot>
[17:09:18] <etla> more like laser tweezers
[17:09:24] <alex_joni> lol, ok
[17:09:50] <skunkworks> we tried cutting glass once ;)
[17:09:51] <owhite> kerf is 100micron
[17:10:05] <etla> so I'm back to the problem with my pushbuttons on the jog-pendant
[17:10:21] <etla> I want one push of the button to turn on coolant, and the next push to turn it off.
[17:10:27] <etla> any good ideas ?
[17:10:57] <cradek> etla: yeah, get another button :-)
[17:13:48] <owhite> does anyone know of a good source for electromagnets? answering "ebay" lacks creativity.
[17:14:19] <etla> is there more to it than a coil with an iron core ?
[17:15:17] <owhite> not really. but I want a relatively good quality one with flat steel surface. I wuoldnt want to wrap them myself.
[17:19:21] <cradek> do you have to pause at the beginning of the cut to let it burn through, or is it so fast that it doesn't matter?
[17:19:52] <cradek> (I see it definitely has some blowout)
[17:20:39] <cradek> also how are you controlling on/off?
[17:22:42] <owhite> cradek, those comments to me?
[17:23:22] <alex_joni> owhite: no other lasers around
[17:23:39] <owhite> I dont pause at the beginning of the cut, although that would be very helpful in some cases (*waits for the comment you can do that with hal-something*).
[17:23:53] <alex_joni> owhite: G4 dwell
[17:24:00] <owhite> it was the hal-circuit thing.
[17:24:02] <alex_joni> how do you switch laser on?
[17:24:41] <owhite> with what command you mean? M3, which has been tied to a laser-activate.
[17:24:57] <owhite> (thanks to you showing me hal-pin stuff)
[17:25:17] <alex_joni> oh, so you M3 before the move, M5 afterwards?
[17:25:42] <owhite> yeah.
[17:25:49] <owhite> will dwell work with that?
[17:26:02] <alex_joni> guess so
[17:26:05] <alex_joni> M3 G4 P.1
[17:26:57] <owhite> I'll try it on my next set of cuts.
[17:33:12] <owhite> check out these brackets I'm making
http://www.nilno.com/100_0348.jpg
[17:33:37] <owhite> on the right side is the flat piece that gets cut. then you can fold it with plyers to make the bracket.
[17:34:24] <alex_joni> can you adjust power?
[17:34:30] <owhite> yes.
[17:34:54] <owhite> manually, not in software. its a limitation of the UCS board.
[17:34:59] <owhite> not enought I/O.
[17:35:14] <alex_joni> oh, right
[17:35:39] <alex_joni> I was thinking about those slots you cut to bend it easier
[17:35:50] <alex_joni> was wondering what happens if you do that with less power
[17:36:00] <owhite> bending is fine. that's definitely the fun part too.
[17:36:21] <alex_joni> yeah, but structural strength is greatly diminished
[17:36:32] <owhite> in what sense?
[17:36:57] <owhite> see there are tabs that form a hinge. those remain intact, they dont see any laser.
[17:37:05] <owhite> then you bend along those tabs.
[17:37:37] <skunkworks> it is hard to just score with a laser. -- Too messy
[17:38:16] <owhite> yah scoring is possible, but its definitely a bit too much adjusting.
[17:39:13] <owhite> this method is basically forming a "dotted line" of slits that make the bending pretty simple for this application.
[17:41:03] <skunkworks> the laser at work - we can set up the power in relation to velocity. I would think that could be done with emc also.
[17:41:51] <owhite> wow. that'd mean I could make "grey scales" in a picture.
[17:42:16] <owhite> sort of a laser-engraved picture.
[17:43:45] <cradek> that would be neat
[17:43:53] <alex_joni> yeah, I think I would definately control the laser power from emc2
[17:44:13] <alex_joni> what outputs do you have available still?
[17:44:38] <alex_joni> owhite: maybe you can get that extra-DAC board JonE developed lately
[17:45:01] <owhite> alex_joni: I'm interested.
[17:45:27] <owhite> do you or anyone know of emc users that have used the Mesa Electronics m5i20 board?
[17:45:49] <owhite> I was thinking of adding that -- its a pretty good price.
[17:46:09] <etla> owhite: i have an m5i20
[17:46:18] <skunkworks> rayh also I think
[17:46:52] <owhite> etla: nice to know. do you have any diagrams of circuitry between the m5i20 and your encoders?
[17:47:06] <owhite> I was having a hard time getting how they were connected from their documention.
[17:47:25] <owhite> A+ A- B+ B- etc...
[17:47:39] <etla> the inputs on the m5i20 are single ended
[17:47:50] <etla> so one A, one B, and one index, usually named Z
[17:48:12] <etla> I've made optoisolators, so the encoder signals will go through the optos
[17:48:25] <alex_joni> A+ and A- are actually equivalent (but negated) so using only one is just fine
[17:48:31] <owhite> huh. I havent heard of that 'singled ended' method.
[17:48:36] <owhite> oh.
[17:48:40] <owhite> okay.
[17:48:52] <skunkworks> I don't see why you need to isolate encoder signals.
[17:49:18] <owhite> are there any major gotchas with the m5i20?
[17:49:19] <skunkworks> they are by their very nature - isolated
[17:52:41] <owhite> * owhite thinks its cool he can sit at his machine and watch g-codes fly by and also watch the #emc discussions. (I figure most users have gotten over this type of excitement by now).
[17:53:08] <skunkworks> * skunkworks hasn't
[17:54:30] <owhite> * owhite has set the topic "The greatest benifit of the internet: showing nerds they arent alone"
[17:54:55] <Lerneaen_Hydra_> * Lerneaen_Hydra_ want's the topic "for great justice!"
[17:54:58] <Lerneaen_Hydra_> err, wants
[17:55:05] <Lerneaen_Hydra_> Lerneaen_Hydra_ is now known as Lerneaen_Hydra
[17:56:30] <skunkworks> owhite: You should try to get to the cnc workshop this spring
[17:57:20] <owhite> where's dat?
[17:57:59] <alex_joni> Lerneaen_Hydra:
http://lostpedia.com/wiki/The_Hydra#Name_References
[17:58:34] <Lerneaen_Hydra> alex_joni: indeed
[17:58:50] <skunkworks> owhite: Galesburg, IL
[18:00:07] <skunkworks> :)
http://www.electronicsam.com/images/KandT/cncworkshop/cncworkshopemc.jpg
[18:01:39] <owhite> skunkworks: I could probably make that. :-)
[18:02:41] <skunkworks> then you get to meet most of the goofballs on this channel. Still trying to get alex to come. lerneaen would have a long treck also.
[18:03:11] <owhite> * owhite is quite interested.
[18:03:14] <Lerneaen_Hydra> heh, I would also be a bit out of place too ;)
[18:03:27] <Lerneaen_Hydra> I'm still nearly wet behind the ears, as it were
[18:03:32] <owhite> could I bring my laser an do a demo?
[18:03:40] <skunkworks> Definatly
[18:03:50] <skunkworks> lots of people bring stuff to show.
[18:04:08] <owhite> just kidding. The laser has a chiller that's the size of a washing machine.
[18:04:15] <skunkworks> So?
[18:04:19] <skunkworks> :)
[18:04:18] <owhite> I would bring stuff that I'd designed at cut.
[18:04:26] <owhite> s/at/and/
[18:05:18] <skunkworks> ^ that picture is of most of the hardcore emc programmers.
[18:06:39] <owhite> they look the part :-)
[18:07:20] <cradek> hey we're beautiful in our own ways
[18:08:59] <Lerneaen_Hydra> were there any other wet-behind-the-ears people there last year?
[18:09:22] <skunkworks> Yes
[18:10:25] <skunkworks> (it is more than emc - but that is the main reason I went.)
[18:10:49] <skunkworks> there is mach classes and other venders selling thier wares. swap meet and such
[18:13:26] <owhite> I ddnt know how accurate my system was so I set the laser to cut a 1.0 diameter circle. According to my (very cheap) micrometer its 1.007 inches.
[18:15:31] <skunkworks> are you measuring the hole or the slug?
[18:16:30] <owhite> the slug. that's a good point. if my kerf is 100 micron, it should be smaller than an inch.
[18:16:49] <skunkworks> right
[18:17:14] <owhite> on the other hand I think I have a very questionable micrometer. came from ebay for $40.
[18:17:59] <skunkworks> that is more than I spent on mine :) 9.99 from homier
[18:18:02] <skunkworks> :)
[18:18:10] <skunkworks> for my kick around set
[18:18:24] <owhite> yah.
[18:25:38] <jmkasunich> even a $9.99 micrometer should be able to tell the difference between 1.000 and 1.007
[18:25:58] <skunkworks> owhite: next time robin_z is around - you should pick his brain. He seems to have a lot experience with lasers among other things.
[18:26:30] <skunkworks> jmkasunich: my 9.99 one seems pretty decent. No issues with it.
[18:26:34] <owhite> jmkasunich: fair enough.
[18:27:06] <Lerneaen_Hydra> skunkworks: is it genereal cnc or emc/mach/similar cnc or something else entirely (fest that is)?
[18:27:46] <skunkworks> Lerneaen_Hydra: about all I can say is 'Yes'
[18:28:09] <Lerneaen_Hydra> to a three choice question?
[18:31:45] <skunkworks> :) there is general cnc, classes on mach and similar stuff also cad, last time there was also casting and anodizing demos
[18:32:41] <owhite> *uses much thinner stainless steel sheet metal for the first time, and immediately cuts his finger*
[18:33:22] <owhite> I will forgoe cauterizing with the laser.
[18:39:45] <Lerneaen_Hydra> skunkworks: oh, cool
[18:44:57] <skunkworks> owhite: do you control hight? or do you manually adjust it?
[18:45:57] <skunkworks> http://www.empirescreen.com/adiemaking.html
[18:46:24] <owhite> its manual
http://nilno.com/laser_intro/front.jpg
[18:46:42] <owhite> you can see a micrometer thing on the side of the cutting head.
[18:48:05] <owhite> this also shows it:
http://nilno.com/laser_dir/pics/processing_head.jpg
[18:49:08] <skunkworks> I see. nice
[18:49:45] <skunkworks> looks like you cool the lense also?
[18:50:15] <owhite> nope that tube feeds oxygen into the cutting head.
[18:50:21] <skunkworks> ah - ok
[18:50:36] <skunkworks> pure oxygen?
[18:50:40] <owhite> yep.
[18:50:50] <skunkworks> Bet that helps cutting metal
[18:50:56] <owhite> goes straight out of the cutting head and right into the basement.
[18:51:09] <owhite> yep. its supposed to raise the temperature of the cut.
[18:51:24] <owhite> they say you can also use nitrogen but its much slower.
[18:54:34] <skunkworks> what kind of pressure?
[18:55:33] <owhite> i use 60 psi for most applications.
[18:56:11] <skunkworks> we run 60psi of just compressed air to cut 3/4 die board
[18:56:43] <owhite> right now I am trying to cut a thing that looks very much like an encoder wheel, and the combination of thin metal and oxygen is making me burn right through the close cuts. so I happen to be experiementing with the pressure.
[18:57:09] <owhite> entertaining to watch metal burn when it doesnt work properly.
[18:58:01] <owhite> I'm also not convinced that this stainless steel that I ordered from ebay is really stainless steel -- it doesnt cut very well.
[19:00:32] <jmkasunich> you order metal from ebay?
[19:02:02] <owhite> sure. search under "stainless sheet" you get a lot of hits.
[19:02:17] <jmkasunich> yeah, but you get mystery metal
[19:02:30] <jmkasunich> I guess if the prices are very low its worth taking the chance
[19:02:39] <jmkasunich> how thick are your sheets?
[19:03:41] <owhite> I bought a 500lb pallet load of 0.032 inch thick.
[19:03:52] <jmkasunich> wow
[19:03:56] <jmkasunich> how much $?
[19:04:13] <jmkasunich> if its not the right alloy you're kinda screwed aren't you? thats a lot of mystery metal
[19:04:27] <owhite> it was a great deal. theres a laser shop that cuts stainless for kitchens they sold me all this "scrap". for $1 a pound!
[19:04:42] <jmkasunich> ah
[19:04:44] <jmkasunich> what about shipping?
[19:05:23] <owhite> all the pieces that came were guaranteed the same kind (304) and to be at least a certain size and width. I dont remember what the shipping was. I was thrilled with the price. everything else was $2-3 a pound.
[19:05:39] <owhite> I almost just drove up to get it myself, but the shipping wasnt bad. maybe $50.
[19:05:39] <jmkasunich> I guess if you need a lot that makes sense
[19:05:57] <owhite> heh. well that's the joke, I probably havent cut 40lbs yet.
[19:06:07] <jmkasunich> I'm used to needing smaller amounts, and convenience + knowing exactly what I'm getting means I get it from either McMaster Carr or Metal Express
[19:06:23] <owhite> ...I figure by the time I go through that load we'll all have 200 watt lasers that you can buy from home depot.
[19:06:34] <owhite> yeah. I like metal express.
[19:07:00] <owhite> but there's a "raw materials" category on ebay that's also really competitive.
[19:08:59] <owhite> this metal is so thin I can take my power down to 30%.
[19:09:05] <SWPadnos> silence ensues, as everyone goes to browse the "raw materials" category on eBay :)
[19:18:32] <owhite> hey does anyone know what I could tweak in the .ini file to make my motors have more "streghth"?
[19:18:41] <SWPadnos> what kind of motor?
[19:18:51] <owhite> servos.
[19:19:15] <owhite> what I mean by strength is that they are 20 amp motors but its still pretty easy to prevent them from rotating.
[19:19:25] <owhite> alex_joni: you awake?
[19:19:25] <SWPadnos> well, assuming that the motors are actually strong enough, I think you increase D to increase "stiffness"
[19:19:50] <SWPadnos> but it really depends on the motor driver and power supply
[19:20:04] <owhite> ah. mine is set to 1.
[19:20:22] <owhite> strike that 0.1
[19:20:46] <owhite> would anyone hazard a suggestion for how much to increase it?
[19:20:58] <SWPadnos> so, you can turn the shaft by hand relatively easily until you get a following error?
[19:21:27] <owhite> um, somewhat easily.
[19:21:39] <owhite> more force than turning a door knob say.
[19:22:05] <SWPadnos> ok, it looks like you're using an m5i20, what motor drivers?
[19:22:33] <SWPadnos> (I could be wrong - I was just scanning the log)
[19:22:47] <owhite> nope. a Universal Steper Controller going to gecko drivers to servos.
[19:22:53] <SWPadnos> ah, ok
[19:23:02] <SWPadnos> have you tuned the geckos?
[19:23:14] <owhite> yes. oscilloscape and everything.
[19:23:42] <SWPadnos> well, then I'd say there's something wrong with the geckos or the power supply (or the tuning)
[19:23:55] <SWPadnos> it's the gecko PID that actually determines stiffness
[19:23:59] <owhite> so you dont think tweaking D would do it?
[19:24:05] <owhite> oh drat.
[19:24:27] <SWPadnos> unless that's jus tthe torque of those motors. what are the motor specs?
[19:24:36] <owhite> hmm....
[19:24:58] <owhite> http://www.nilno.com/laser_intro/power_supply.html
[19:25:09] <SWPadnos> I have relatively beefy motors - 27 in-lb, and I can pretty easily cause them to fault if I put a handwheel on the motor shaft
[19:25:22] <SWPadnos> also with geckos
[19:25:50] <owhite> wait, sorry.
[19:25:55] <owhite> http://www.nilno.com/laser_intro/table.html
[19:26:03] <owhite> that has the motor information.
[19:26:26] <SWPadnos> ok - 300 oz-in continuous
[19:26:39] <owhite> *nod*
[19:26:45] <SWPadnos> 300 oz is <19 lbs at 1" radius
[19:27:00] <owhite> oh well hey, I'd say I'm about there.
[19:27:08] <SWPadnos> hmmm - what's the gecko current limit set to?
[19:27:21] <SWPadnos> it should probably be all the way up to 20A
[19:27:32] <owhite> not sure, its been a while. I think I went with 20A.
[19:27:36] <SWPadnos> ok
[19:28:04] <owhite> I bet this is actually 19lbs force.
[19:28:18] <owhite> *torques on motor with hand*
[19:28:20] <SWPadnos> are you just grabbing the shaft, or is there a handle?
[19:28:21] <SWPadnos> ok
[19:28:45] <owhite> theree is a pulley
http://nilno.com/laser_dir/motor_mount2.jpg
[19:28:51] <SWPadnos> it should be higher for a 5/8" shaft diameter - about 3x, but it's still within the human realm
[19:29:12] <SWPadnos> ok, if you're grabbing the belt or pulley, then that's close to the 19lb figure
[19:29:25] <owhite> yeah I really think it is.
[19:29:29] <SWPadnos> at least it looks like something close to 1" radius
[19:29:52] <SWPadnos> I was quite surprised to be able to stop my motors as well, but then again, I can turn the handles on my bridgeport just as well as the motor
[19:30:03] <owhite> I have a mechanical problem. at the end of run of the ballscrew it gets harder to turn, and the motor fails.
[19:30:23] <Lerneaen_Hydra> 'lo again
[19:30:22] <owhite> then it screws up my run of course.
[19:30:25] <SWPadnos> is the ballscrew worn, or does it need some cosmoline cleaned off? ;)
[19:30:38] <SWPadnos> hiya lh
[19:30:59] <owhite> its a really nice table, the ball screw is protected with a enclosure.
[19:31:13] <Lerneaen_Hydra> logger_emc: bookmark
[19:31:13] <Lerneaen_Hydra> Just this once .. here's the log:
http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2006-11-11.txt
[19:31:16] <owhite> I love my table. retailed for $25k, on ebay -- $500.
[19:31:41] <SWPadnos> heh
[19:32:15] <owhite> I think theres a little alignment problem.
[19:32:40] <owhite> thought I could fix it with stiffer motors, but I guess I have to try to do some finessing
[19:33:07] <owhite> *powers down and gets out the allen wrenches*
[19:33:08] <SWPadnos> you're better off fixing the problem - it would only go away when the parts wear out enough
[19:33:19] <SWPadnos> and that's not the best plan
[19:33:56] <owhite> the table is really a thing of beauty.
http://nilno.com/laser_intro/table0.jpg
[19:34:17] <owhite> not such a good picture of the mechanics.
[19:34:28] <Lerneaen_Hydra> is alex here?
[19:34:42] <SWPadnos> he was a few hours ago
[19:35:04] <Lerneaen_Hydra> or does anyone else know how to redirect /var/www to /home/user/public_http ?
[19:35:36] <SWPadnos> that'll be in /something/else/httpd.conf, I think ;)
[19:35:47] <SWPadnos> one sec
[19:36:09] <Lerneaen_Hydra> this is on apache 2.0
[19:37:18] <SWPadnos> /etc/apache2/apache2.conf, "UserDir"
[19:37:32] <SWPadnos> there are commented lines that you probably just need to uncomment
[19:38:39] <SWPadnos> around line 205 in my file
[19:39:03] <Lerneaen_Hydra> so uncomment it and set it to /home/user/http_public?
[19:39:44] <SWPadnos> actually, it looks like the setting should be "public_html", as the sample shows
[19:39:49] <SWPadnos> hi Ray
[19:40:03] <rayh> Hi Steven.
[19:40:23] <owhite> * owhite has to reboot.
[19:40:39] <Lerneaen_Hydra> then how does apache know which user's folder to go into?
[19:41:09] <SWPadnos> any request for /~user will go to that user's ~/public_html dir instead
[19:41:28] <SWPadnos> unless the user is listed as disabled (like root in the example)
[19:41:48] <Lerneaen_Hydra> oh, that's not what I wanted, I wanted <ip> to go to <ip>/~user
[19:42:09] <Lerneaen_Hydra> the /~user to /~user/public_html link is already done
[19:42:23] <Lerneaen_Hydra> maybe I should just move it to /var/www
[19:43:25] <SWPadnos> hmmm - I guess I don't really understand the question :)
[19:43:55] <SWPadnos> oh wait - you want the www root to be ~someone/somedir?
[19:44:15] <SWPadnos> I think that may be an alias thing
[19:44:20] <Lerneaen_Hydra> nearly, www root should be ~/someone
[19:44:40] <Lerneaen_Hydra> either that or I can move the entire dir to /var/www, which may be better
[19:45:10] <SWPadnos> make /var/www a link to the user's dir?
[19:45:23] <SWPadnos> or alias / ~user/html
[19:45:37] <Lerneaen_Hydra> yeah that sounds doable
[19:45:53] <SWPadnos> there are several aliases in the default file I have
[19:46:03] <SWPadnos> examples anyway
[19:46:12] <Lerneaen_Hydra> do you mean the apache config file?
[19:46:17] <SWPadnos> yep
[19:46:32] <Lerneaen_Hydra> is there a benefit in keeping the file in ~/user?
[19:46:59] <SWPadnos> dunno - I gues sit would depend on why you're doing it that way in the first place
[19:47:18] <Lerneaen_Hydra> no reason really
[19:47:24] <SWPadnos> heh
[19:47:38] <Lerneaen_Hydra> I assumed that was standard practice
[19:48:13] <SWPadnos> no, I think it's more standard to give the user who maintains the site access to /var/www or wherever the server is configured to serve from)
[19:48:46] <Lerneaen_Hydra> oh, ok
[19:48:54] <Lerneaen_Hydra> * Lerneaen_Hydra moves the stuff to /var/www
[19:48:57] <SWPadnos> heh
[19:52:00] <SWPadnos_> SWPadnos_ is now known as SWPLinux
[20:04:55] <Lerneaen_Hydra> can someone test lerneaenhydra.shacknet.nu ?
[20:05:05] <Lerneaen_Hydra> err,
http://lerneaenhydra.shacknet.nu
[20:05:21] <Lerneaen_Hydra> should be a generic template page
[20:08:02] <anonimasu> it works..
[20:08:08] <anonimasu> but it's really slow
[20:08:16] <anonimasu> err
[20:08:20] <anonimasu> your setup is fucked up..
[20:08:21] <anonimasu> :)
[20:08:21] <rayh> It seems to stall out right after the page title comes through -- dialup though.
[20:08:31] <anonimasu> 192.168.1.20
[20:08:31] <anonimasu> ;)
[20:08:35] <anonimasu> where's that :)
[20:08:57] <Lerneaen_Hydra> err
[20:09:02] <eholmgren> heh
[20:09:13] <Lerneaen_Hydra> wtf, must be an internal thing
[20:09:16] <eholmgren> how do you know the IP of one of the servers on my private lan ?!@#
[20:09:19] <eholmgren> ;)
[20:09:33] <anonimasu> wait until you see this one..
[20:09:39] <anonimasu> 10.0.0.5 <- the DOD main server
[20:09:40] <anonimasu> :D
[20:10:00] <eholmgren> my workstation at work is 10.0.0.4
[20:10:05] <eholmgren> they must be right next door
[20:10:05] <Lerneaen_Hydra> no, I set the adress to that, but I wonder if I'll be able to config it from within my LAN after setting it to the WAN adress
[20:10:57] <CIA-5> 03swpadnos 07HEAD * 10emc2/src/hal/components/blend.comp: Fix typo in output formula
[20:11:00] <anonimasu> yes
[20:11:08] <anonimasu> you should be able to
[20:11:22] <anonimasu> laters
[20:11:56] <Lerneaen_Hydra> bye
[20:13:50] <Lerneaen_Hydra> and now?
[20:13:52] <Lerneaen_Hydra> worky?
[20:15:02] <SWPLinux> worky here
[20:15:33] <Lerneaen_Hydra> hmm, this could be nasty, my router doesn't let me connect to my external IP and redirect to my internal ip
[20:15:56] <Lerneaen_Hydra> ie if I type my external IP in the adress bar it doesn't redirect with NAT correctly
[20:16:04] <SWPLinux> that's much more of a pain in the ass than you might imagine
[20:16:06] <Lerneaen_Hydra> yeah
[20:16:08] <Lerneaen_Hydra> it is
[20:16:10] <SWPLinux> no, it wouldn't
[20:16:34] <SWPLinux> I know one office where they just put the internal IP of the server in the hosts file on all computers
[20:16:42] <Lerneaen_Hydra> hmm, that would work
[20:16:51] <SWPLinux> and that's with a $1000+ router/firewall as theiur NAT box
[20:16:59] <Lerneaen_Hydra> on the client computer I assume?
[20:17:10] <SWPLinux> yep - all the workstations on the local net
[20:17:24] <Lerneaen_Hydra> ok, now wth is the hosts file in doze...
[20:17:37] <SWPLinux> /windows/hosts?
[20:17:58] <Lerneaen_Hydra> hmm, nope
[20:18:00] <owhite> hey. a friend with a really old video game needed a new encoder for his joystick....
http://www.nilno.com/100_0349.jpg
[20:18:03] <Lerneaen_Hydra> it can't be that simple in windows
[20:18:13] <owhite> ...so made one :-)
[20:19:18] <cradek> cool!
[20:19:30] <Lerneaen_Hydra> C:\WINDOWS\SYSTEM32\DRIVERS\ETC <-- wtf is up with ms putting the hosts file there!
[20:19:46] <owhite> yeah maybe I could give US DIgital encoders a run for their money.
[20:20:11] <cradek> does it work?
[20:20:28] <SWPadnos> they're trying to emulate UNIX - notice the etc at the end ;)
[20:20:32] <Lerneaen_Hydra> haha, yeah
[20:20:45] <owhite> cradek: dont know I'll get it to him on monday, he can try it.
[20:20:51] <Lerneaen_Hydra> I wonder how I get it to relead the file
[20:21:33] <Lerneaen_Hydra> bah, rebooting
[20:21:35] <SWPadnos> reboot
[20:21:35] <Lerneaen_Hydra> brb
[20:25:15] <Lerneaen_Hydra> iab
[21:25:05] <robin_sz> meep?
[21:26:47] <owhite> *wave*
[21:49:09] <Lerneaen_Hydra> alex_joni: you there?
[21:49:16] <Lerneaen_Hydra> joomla is t3h shit!
[21:49:32] <Lerneaen_Hydra> http://lerneaenhydra.shacknet.nu/
[21:49:48] <Lerneaen_Hydra> not populated yet, but it certainly is easy to work with :D
[21:56:58] <Lerneaen_Hydra> there's tons and tons of content in it though, it will take a while to learn ;=
[21:57:01] <Lerneaen_Hydra> *;)
[22:30:34] <Lerneaen_Hydra> * Lerneaen_Hydra pokes alex
[22:31:00] <Lerneaen_Hydra> you don't by any chance know of a good introduction page to joomla?
[22:32:18] <alex_joni> Lerneaen_Hydra: nope
[22:32:25] <Lerneaen_Hydra> ok
[22:32:27] <alex_joni> but it's pretty much self explaining
[22:32:32] <Lerneaen_Hydra> * Lerneaen_Hydra continues to play around with it
[22:32:33] <Lerneaen_Hydra> yeah
[23:32:11] <Lerneaen_Hydra> can anyone test the responsiveness of lerneaenhydra.shacknet.nu ? how snappy/bogged down does it feel?
[23:32:47] <jepler> not instant to load but not too slow
[23:32:49] <SWPadnos> seems reasonably quick
[23:33:03] <Lerneaen_Hydra> ok, so good enough for most purposes?
[23:33:09] <SWPadnos> yep
[23:33:15] <Lerneaen_Hydra> perfect :)
[23:33:17] <SWPadnos> not google quick, but not sial-up either ;)
[23:33:19] <SWPadnos> dial-up
[23:33:34] <anonimasu> yep
[23:33:58] <rayh> Still a bit slow on my slow dialup. The top banner/image is the last to get here.
[23:34:16] <rayh> Before that was the left side menu.
[23:36:05] <anonimasu> hm it's pretty ok
[23:36:10] <anonimasu> not "snappy" though :)
[23:38:05] <Lerneaen_Hydra> it's only hosted on a 0.1mbit up connecteion
[23:38:10] <Lerneaen_Hydra> and latency is so-so
