[00:01:27] <SWPadnos> yes
[00:01:38] <SWPadnos> even for more $$, for some value of "more"
[00:02:19] <SWPadnos> I have 50 oz-in servos I got off eBay. they run up to 5000 RPM, have 1000 line encoders (and tach, if I want to use it)
[00:02:27] <ds2> Hmmmm wonder why Fred doesn't get a better reception...his servo offerings seems to cost about the same as a stepper setup
[00:02:38] <SWPadnos> a servo won'g run past about 1500 RPM and still deliver any reasonable torque to the load
[00:02:39] <SWPadnos> won't
[00:03:02] <ds2> eh?
[00:03:06] <SWPadnos> I'm not sure. I think people don't like deskCNC
[00:03:08] <Rugludallur> SWPadnos: don't you mean stepper
[00:03:13] <SWPadnos> and they also don't seem to like Fred, I think ;)
[00:03:19] <ds2> hehe
[00:03:29] <SWPadnos> Rugludallur, yes, I did mean stepper there - thanks :)
[00:03:37] <ds2> ah okay
[00:04:05] <ds2> if I had to do a CNC conversion, the stuff Fred's pushing seems ideal
[00:04:05] <SWPadnos> so if I gear this motor down 3:1, then I have the same torque at the output, except that I can go to 4x torque if I want to
[00:04:30] <SWPadnos> and also, I get full torque at full speed - not full torque up to ~800 RPM, then decreasing torque
[00:04:31] <ds2> but you pay for it in backlash, no?
[00:04:40] <SWPadnos> not with a belt drive
[00:04:49] <SWPadnos> and I also have feedback
[00:05:18] <SWPadnos> (I would also have 12000 steps/revolution at the output shaft, so that might be a problem ;) )
[00:05:20] <ds2> hmmm most references say the cog belts are mostly backlash free
[00:05:32] <SWPadnos> yes, belts are generally considered backlash-free
[00:05:36] <ds2> that fits in 16bits
[00:05:42] <SWPadnos> especially Gates GT2
[00:05:51] <ds2> no one really says they are completely backlash free, just mostly
[00:06:05] <anonimasu> there are backslash reduced belts
[00:06:16] <SWPadnos> well, if I have a 10 TPI screw (or an additional 2:1 to a 5 TPI), then I have 120000 steps/inch, which would require hardware step generation for any reasonable speeds
[00:06:21] <SWPadnos> or a real servo drive ;)
[00:06:43] <SWPadnos> I think if properly tensioned, they're considered backlash-free
[00:06:52] <ds2> I see
[00:07:00] <SWPadnos> as long as you have one of the better profiles (L/XL are OK, HTD are good, GT2 are better)
[00:07:13] <anonimasu> GT2 is what I use I think..
[00:07:17] <ds2> so 120KHz to run it at 10inch-second
[00:07:27] <SWPadnos> no, 120 KHz to run at 1 inch/second
[00:07:37] <SWPadnos> that 12000 was at the output of my 3:1 reducer
[00:07:38] <anonimasu> actually no.. it's very similiar
[00:07:42] <SWPadnos> (hypiothetical, of course)
[00:07:46] <ds2> yeah, that's what I mean
[00:07:56] <anonimasu> "synchroflex"
[00:08:06] <SWPadnos> yep - so 60 IPM at 120KHz. ~120 IPM at the limit of a gecko (250 KHz)
[00:08:28] <ds2> a parallel port can keep up ;)
[00:08:41] <SWPadnos> not with an OS :)
[00:08:57] <ds2> couldn't you use the parallel port as a parallel load shift register instead?
[00:09:22] <SWPadnos> possibly, with custom hardware ;)
[00:09:38] <ds2> uh..custom? a single 7400 series chip :P
[00:09:51] <ds2> or something toss into a 22V10
[00:09:52] <SWPadnos> with all the strobe / ack crap added
[00:09:59] <SWPadnos> yeah - a GAL would do it
[00:10:31] <ds2> don't consider a GAL to be too much of a custom thing
[00:10:51] <SWPadnos> well, you still need a board, and a schematic, and some code (of some sort) ...
[00:10:58] <SWPadnos> plus the HAL driver
[00:11:03] <ds2> bah board
[00:11:09] <ds2> just solder it onto a DB-25 direct
[00:11:20] <SWPadnos> heh - just solder on wires and stick 'em in the port, eh?
[00:11:26] <ds2> "code" is just some palasm :P
[00:11:31] <SWPadnos> no power on a parport ...
[00:11:53] <ds2> the Lattice ones should be low enough to be parasitic powered }:-)
[00:12:09] <SWPadnos> heh - just use a few extra outputs as "enables" ;)
[00:12:28] <ds2> no worse then those protection dongles
[00:12:35] <SWPadnos> true
[00:12:49] <ohiopctechDOTcom> yo...
[00:13:07] <SWPadnos> yo yo yo boyz!
[00:13:13] <ds2> if it isn't obvious... still not too FPGA comfortable yet
[00:13:14] <ohiopctechDOTcom> the guy who taught me how to run the first cnc i ever touched was just here to check out the mini mill
[00:13:30] <ohiopctechDOTcom> he said "that's fscking awesome dude!"
[00:14:12] <ohiopctechDOTcom> he runs a hurco all day at the first shop i ever worked at
[00:14:37] <ohiopctechDOTcom> he quit there and worked for me and my dad for a while then went back there
[00:14:54] <ds2> calling your thing a "mini mill" is misleading :P
[00:14:54] <cradek> jepler: differential works!
[00:15:03] <ohiopctechDOTcom> ha.. it is a mini mill though
[00:15:13] <ohiopctechDOTcom> it's more than just an engraver...
[00:15:21] <ds2> mini mill is the thing that haas makes with a 1-1.5HP spindle ;)
[00:15:31] <ohiopctechDOTcom> it's a fully functional 3 axis mill (except if the function is cutting steel)
[00:15:55] <ohiopctechDOTcom> 3 axis CNC MILL***
[00:16:08] <ds2> it lacks flood coolant }:-)
[00:16:19] <ohiopctechDOTcom> i got a squirt bottle
[00:17:05] <ohiopctechDOTcom> anyways.... dude is gonna bring me some steel for the new machine i'm building..
[00:17:44] <ohiopctechDOTcom> (he works by the backdoor)
[00:17:48] <ohiopctechDOTcom> :)
[00:17:53] <ds2> will that be a "router" or a mill?
[00:18:03] <ohiopctechDOTcom> technically a router
[00:18:22] <ohiopctechDOTcom> with light milling possibly
[00:20:12] <ohiopctechDOTcom> i just put my psp on ebay for 100 bones if anybody wants it.. (proceedes will buy my steppers for the router)
[00:20:28] <ohiopctechDOTcom> :( i'll miss the lil' guy
[00:25:56] <skunkworksemc> cradek: you put differential receivers on your board?
[00:26:08] <skunkworksemc> for the spindle encoder?
[00:26:23] <cradek> yes
[00:26:44] <cradek> it was finicky before, so I thought doing it right might help
[00:27:05] <skunkworksemc> I wonder if the issues you where having where the same issues I had with the cable?
[00:27:11] <cradek> a smart friend used to say "when in doubt, do it right"
[00:27:25] <cradek> I wish I could remember for sure, but I think I still had troubles after that was fixed
[00:27:48] <cradek> now I'm at the "mounting everything" phase, which is always the hardest for me
[00:28:08] <ohiopctechDOTcom> aluminum angle always makes good brackets
[00:28:18] <JymmmEMC> * JymmmEMC LOL @ cradek
[00:28:27] <cradek> JymmmEMC: ?
[00:28:59] <JymmmEMC> * JymmmEMC pictures cradek mounting the leg of everyone like a horny dog humping everythin LOL
[00:29:24] <skunkworksemc> I hate that part.. It works so why should I dress it up ;)
[00:29:40] <ohiopctechDOTcom> i've used steel from an old pc case and bent it in a homebrew brake to bend it for sensor brackets in the past...
[00:31:33] <JymmmEMC> http://www.fotosearch.com/comp/phd/PHD427/92041.jpg
[00:32:15] <SWPadnos> JymmmEMC, I'm almost curious as to why you have that image of cradek in your mind
[00:32:33] <ohiopctechDOTcom> JymmmEMC: http://www.grandtimes.com/dogs.html
[00:32:38] <SWPadnos> ah - now I see. I missed that last stanza
[00:32:38] <JymmmEMC> SWPadnos: cradek: now I'm at the "mounting everything" phase,
[00:32:39] <cradek> JymmmEMC: those were supposed to be SECRET rendezvous! SECRET
[00:32:49] <JymmmEMC> cradek: LOL
[00:33:07] <JymmmEMC> cradek: Nobody's listening =)
[00:33:08] <ohiopctechDOTcom> "NO MORE SECRETS" ... didn't you see the movie sneakers?
[00:33:30] <ohiopctechDOTcom> *iif you haven't seen it you should!
[00:33:35] <SWPadnos> no, but there's a great brnch place near here called Sneakers
[00:33:39] <SWPadnos> brunch
[00:33:48] <SWPadnos> best eggs ebnedict anywhere
[00:33:51] <SWPadnos> argh
[00:33:56] <SWPadnos> best eggs benedict anywhere
[00:34:02] <JymmmEMC> SWPadnos: shush
[00:34:16] <ohiopctechDOTcom> ...it's a movie about the nsa and the kgb fighting over a super decryption electronic box, so they can spy on anyone
[00:34:23] <SWPadnos> well, anywhere I've tried anywhere
[00:34:28] <JymmmEMC> ohiopctechDOTcom: I have it right here
[00:34:44] <SWPadnos> in this era, we call that "sneakery-ers"
[00:34:45] <ohiopctechDOTcom> JymmmEMC: has to be on my list of fav movies
[00:34:45] <JymmmEMC> along with Hackers too
[00:35:23] <cradek> I think a lot of sneakers was too corny to stand
[00:35:29] <JymmmEMC> ohiopctechDOTcom: I love what they make a deal for (no spoilers in here)
[00:35:30] <ohiopctechDOTcom> hackers was a lil too far fetched.. but interesting none the less...
[00:35:44] <cradek> the place where the "encrypted" text on the screen changed bit by bit into a map
[00:35:58] <cradek> the way the screens projected the text onto their faces
[00:36:18] <ohiopctechDOTcom> yes.. they had to make it fancy for the movie.. but the general storyline is do-able in real life
[00:36:20] <cradek> and they really overdid the blind guy's character
[00:36:26] <ohiopctechDOTcom> something like it might have really happened
[00:36:35] <cradek> he's BLIND everyone! BLIND! that means he has super powers!!
[00:36:43] <ohiopctechDOTcom> ha
[00:37:55] <ohiopctechDOTcom> can the blind man fly?
[00:38:20] <ohiopctechDOTcom> there should be some movies about crazy CNC tool shop drama...
[00:38:22] <ds2> given enough thrust...
[00:38:58] <ohiopctechDOTcom> where the big name cnc guys are always hassleing the emc homebrew guys to buy big name stuff.
[00:39:24] <skinnypuppy1334> I've seen some funny stuff around the tech school... more broken endmills than you know what to do with
[00:39:28] <ohiopctechDOTcom> ... then one day the haas crew shows up with baseball bats
[00:40:13] <skinnypuppy1334> I like the sl20 at school... can't afford one for the garrage though
[00:41:10] <ds2> Mmmm turrets
[00:41:18] <ds2> tool changers really spoil people
[00:41:41] <ohiopctechDOTcom> what spoiled me was my automatic drawbar
[00:42:04] <skinnypuppy1334> i must admit so, i did a live tooling program to make the center body of a hula hula engine on the haas lathe ...
[00:42:18] <ohiopctechDOTcom> i eventually refused to run the small mill because it ddidn't have the pwer drawbar.. then one day it had a new power drawbar on it!
[00:42:47] <ohiopctechDOTcom> hula hula engine?
[00:43:01] <skinnypuppy1334> from steam and sterling engine ...
[00:43:08] <ohiopctechDOTcom> ohh
[00:43:09] <ds2> skinnypuppy1334: how often does the SL20 have the turret crashing into the chuck?
[00:43:09] <skinnypuppy1334> there is one on youtube
[00:43:17] <ohiopctechDOTcom> i bet i seen it
[00:43:28] <ohiopctechDOTcom> i watched a lot of steam engine vids
[00:43:38] <ohiopctechDOTcom> i'm thinking of building one
[00:43:52] <skinnypuppy1334> I haven't done it yet, but when things get tight I slow it down and watch for crash on dry run
[00:44:13] <skinnypuppy1334> I've seen some really pretty brass candle sterlings on youtube.
[00:44:55] <skinnypuppy1334> I haven't finished making all the parts though
[00:47:35] <skinnypuppy1334> http://youtube.com/watch?v=NZ2CiIq64Lc
[00:47:46] <skinnypuppy1334> A hula hula engine
[00:48:07] <ohiopctechDOTcom> that is badass
[00:49:11] <skinnypuppy1334> Yep, the center part that holds the cylinder back plates is what I made on the haas
[00:49:44] <skinnypuppy1334> Here are two VERY elegant sterlings ...
[00:49:45] <skinnypuppy1334> http://youtube.com/watch?v=VDcedTqRDpg
[00:49:59] <skinnypuppy1334> http://youtube.com/watch?v=cnx_1qFA7OE
[00:50:56] <ohiopctechDOTcom> how do the cylinders get timing?
[00:51:06] <JymmmEMC> 4 deg TDC
[00:51:32] <skinnypuppy1334> holes in the backing plate, one is presurized one exhaust to air
[00:51:34] <ohiopctechDOTcom> is that for chevy JymmmEMC? lol
[00:52:00] <JymmmEMC> ohiopctechDOTcom: hell if I kow, but at least SOMEONE got the joke =)
[00:53:05] <skinnypuppy1334> Having dreams or nightmares of a larger one in place ov a vw aircooled with a nitrogen tank ;o)
[00:53:32] <ohiopctechDOTcom> yeah, that could run a car i bet
[00:53:42] <ohiopctechDOTcom> especially wth a tranny
[00:53:56] <ohiopctechDOTcom> transmission*
[00:54:04] <ohiopctechDOTcom> not the other kind of tranny...
[00:54:10] <skinnypuppy1334> Here is an awsome 7 cylinder radial CUTAWAY in motion
[00:54:13] <skinnypuppy1334> http://youtube.com/watch?v=4hWZ40120BQ
[00:56:21] <skinnypuppy1334> I don't think those trannys would to too well at a "drag strip" ??? I couldn't leave that one alone
[00:57:58] <skinnypuppy1334> This one sounds like a freekin dragster
[00:58:08] <skinnypuppy1334> http://youtube.com/watch?v=G3E2tv8UgfU
[00:59:52] <skinnypuppy1334> Enjoy those... I'll be around later
[01:00:20] <JymmmEMC> One hospital in Japan has a "Baby Drop Off" contianer/incubator. Drop off your baby, and push the button.
[01:00:47] <ohiopctechDOTcom> is it a cnc?
[01:04:17] <ohiopctechDOTcom> http://youtube.com/watch?v=60Tamp2fHhg&mode=related&search= <-- V8 engine powered chainsaw
[01:14:31] <toastydeath> fffff
[01:23:01] <skinnypuppy1334> NOW thats a chainsaw!!!
[01:24:08] <toastydeath> someone needs to hook up the drivetrain from a rolling mill to a chainsaw
[01:25:51] <gringos> anykind of saw
[01:26:25] <toastydeath> maybe an Amada 40"x40" bandsaw?
[01:32:56] <skinnypuppy1334> This 5 axis machine making a scale v-8 block from billet is about the coolest vid i've ever seen Matsuura 5 axis.
[01:32:57] <skinnypuppy1334> http://youtube.com/watch?v=QsmiIeAkE
[01:33:24] <SWPadnos> have you seen the polygon turning video(s)?
[01:33:59] <SWPadnos> http://youtube.com/watch?v=oGq-9NNmr3o
[01:34:18] <SWPadnos> don't forget to laugh at the marketroid voice-over
[01:38:36] <ohiopctechDOTcom> so i want to build an unregulated PS?
[01:38:41] <ohiopctechDOTcom> why not regulated?
[01:39:09] <SWPadnos> there's no need for regulation since the motor driver is a regulator
[01:39:24] <ohiopctechDOTcom> good point..
[01:39:39] <SWPadnos> a bulk supply has lots of overhead as well - the transformer can supply bursts of ~10x its rated current for short periods
[01:39:42] <skinnypuppy1334> That's an interesting way of making a flat on a lathe
[01:39:47] <SWPadnos> err - headroom, that was
[01:40:00] <SWPadnos> yes - that lathe is pretty impressive
[01:42:07] <skinnypuppy1334> This 5 axis milling/turning machine is awsome as well .
[01:42:10] <skinnypuppy1334> http://youtube.com/watch?v=_4vLqfIx8X8
[01:42:38] <SWPadnos> yep - seen that one too :)
[01:43:16] <SWPadnos> and the chain saw milling one as well
[01:43:25] <SWPadnos> http://youtube.com/watch?v=oLH9djDK52I
[01:43:29] <skinnypuppy1334> that thing made my jaw drop, wonder what cad/cam they are using ... couldn't imagine having to program all that
[01:43:44] <ohiopctechDOTcom> mastercam i bet
[01:45:03] <skinnypuppy1334> prob, I used X in class for posts for the heidenhein/bridgeport mill
[01:45:04] <ohiopctechDOTcom> its the shit!
[01:45:48] <skinnypuppy1334> I've got a trial version that came with a learning mastercam unfortunately won't save files or do posts...
[01:49:38] <skinnypuppy1334> Are there any good cad programs for linux yet?
[01:49:47] <ohiopctechDOTcom> qcad
[01:49:49] <lerman_> lerman_ is now known as lerman
[01:49:52] <ohiopctechDOTcom> gcam
[01:50:13] <skinnypuppy1334> I haven't heard of gcam
[01:50:13] <SWPadnos> catia
[01:50:19] <ohiopctechDOTcom> there was a nice looking one someone mentioned a few days ago but i forget the name
[01:50:29] <JymmmEMC> freecad.sf.net
[01:50:31] <skinnypuppy1334> catia $$$
[01:50:37] <ohiopctechDOTcom> yeah that was it JymmmEMC
[01:50:41] <SWPadnos> catia $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
[01:51:19] <skinnypuppy1334> yep... I did like how intuitive it was creating lofts pockets pads fillets etc.... it smokes in that aspect!!!
[01:51:48] <skinnypuppy1334> I'm going to check out the gcam and freecad
[01:52:36] <SWPadnos> the author of gcam is Twingy (in this IRC channel)
[02:02:48] <skinnypuppy1334> Thats nice to know.
[02:06:42] <skinnypuppy1334> I'm getting a 404 error @ freecad.sf.net
[02:07:24] <SWPadnos> http://juergen-riegel.net/FreeCAD/Docu/index.php?title=Main_Page
[02:10:36] <skinnypuppy1334> I'm checking that out, screenshot looks cool
[02:13:06] <skinnypuppy1334> does freecad ouput any g-code?
[02:17:45] <JymmmEMC> skinnypuppy1334: that would be a CAM not CAD proggy
[02:18:20] <JymmmEMC> http://free-cad.sf.net/
[02:19:55] <skinnypuppy1334> Gcam looks pretty cool, how well do its posts work in EMC. I didn;t know if it was cad/cam or cad only
[02:20:33] <cradek> I think emc2 is one of gcam's primary targets
[02:20:36] <JymmmEMC> skinnypuppy1334: http://www.gcam.org/
[02:21:08] <skinnypuppy1334> sweet I was looking at the wiki , I'll check out the .org and bookmark these !
[02:22:59] <skinnypuppy1334> um wrong gcam.org...
[02:23:06] <JymmmEMC> ROTFLMAO
[02:23:21] <JymmmEMC> http://gcam.js.cx/index.php/Main_Page
[02:23:58] <skinnypuppy1334> lots of things i didn't know of tonight ;o)

[02:44:57] <skinnypuppy1334> Is gcam avail through ubuntu repository?
[02:46:02] <cradek> skinnypuppy1334: I think it's only source
[02:46:51] <skinnypuppy1334> Lost connection for some reason, what were you saying is the only source ?
[02:47:03] <skinnypuppy1334> I didn't find it in synaptic
[02:48:52] <cradek> it's only distributed as source
[02:54:48] <skinnypuppy1334> I'm gonna try install the tar.gz
[02:55:09] <bytecolor> needs gtk2.8 too
[03:08:35] <skinnypuppy1334> how do I apt get gtk2.8 in feisty?
[03:09:03] <cradek> I think you don't need to
[03:10:13] <cradek> I built gcam with the default gtk2 stuff that was in dapper
[03:10:23] <skinnypuppy1334> GTK+ 2.8.0 or higher (2.10 or higher recommended for extra features)
[03:10:44] <skinnypuppy1334> I'm told feisty has 2.10
[03:11:16] <cradek> ok, I have 2.8.20-0ubuntu1.1
[03:12:08] <skinnypuppy1334> I'm kind of a newb to terminal syntax in linux, could you tell me how to check my gtk version?
[03:12:55] <cradek> dpkg -l 'libgtk2*'
[03:14:33] <skinnypuppy1334> 2.10.11-0
[03:15:23] <skinnypuppy1334> is that dpkg debian package?
[03:15:56] <cradek> yes
[03:16:53] <skinnypuppy1334> what's the easiest way to install 2.8?
[03:17:11] <cradek> why would you do that?
[03:17:28] <skinnypuppy1334> thought it was dependency for gcam
[03:17:44] <cradek> read what you pasted ten lines up
[03:18:30] <skinnypuppy1334> ok so it is functional under 2.10 then. Thanks. Noob sorry
[03:18:46] <cradek> just try to build it - configure will tell you if anything is wrong
[03:21:31] <skinnypuppy1334> at the end of ./compile
[03:22:21] <skinnypuppy1334> checking for GTK+ - version >= 2.8.0... no

[03:24:23] <cradek> ^^ why people didn't network dos much
[03:24:55] <skinnypuppy1334> installing libgtk. thanks for your patience
[03:25:21] <cradek> often, a package with -dev appended is what's required to compile something that uses it
[03:25:45] <cradek> so the runtime part is libgtk2.0, but to compile something that needs that library, you have to install libgtk2.0-dev
[03:26:21] <skinnypuppy1334> Thanks for pointing that out. It's the developers libs for compiling then?
[03:26:33] <cradek> yes
[03:26:59] <skinnypuppy1334> thanks, I'm just getting used to the guts of linux, but have an IT background
[03:27:22] <skinnypuppy1334> hardware netwrking mostly
[03:27:48] <cradek> I've administered unix machines for years, but I still learn new stuff, especially about new distributions like ubuntu
[03:29:01] <skinnypuppy1334> Sweet, I have been using ubuntu a little more than a year avoiding the MS virus magnet except when absolutely needed
[03:29:17] <cradek> I'm sad/happy to say, though, that leaves me totally clueless about microsoft OSes
[03:30:46] <cradek> it has been really cool to watch Free unix grow up, I sure didn't predict it at first.
[03:31:20] <cradek> at my work we do all development on Free software
[03:31:34] <skinnypuppy1334> yeah I first tried linux when I found out the mcse was going to be no good, since they dreamt up 2000 ... i got a A+ and net+ instead
[03:32:03] <cradek> heh I have no idea what those things are

[03:53:25] <skinnypuppy1334> still can't seem to apt get opengl
[03:55:32] <cradek> I told you above: libgl1-mesa

[04:13:24] <skinnypuppy1334> Is this normal ?
[04:13:33] <cradek> no
[04:13:50] <cradek> but the error is earlier
[04:14:09] <JymmmEMC> Anyone know what the current rating is on typical PC power cords?
[04:14:25] <ds2> 20A?
[04:14:44] <JymmmEMC> really?
[04:14:46] <ds2> scratch that 15A
[04:14:50] <cradek> no more than 15
[04:14:52] <jmkasunich_> scratch that again
[04:14:56] <ds2> the plug is officially a 15A plug
[04:14:59] <cradek> don't they say?
[04:15:03] <jmkasunich_> I bet they're 16AWG or maybe even 18AWG
[04:15:06] <jmkasunich_> 10A
[04:15:17] <cradek> there are definitely different ones
[04:15:23] <jmkasunich_> some are heavier than others
[04:15:27] <cradek> I have a few as big as my thumb off old HP equipment
[04:15:31] <skinnypuppy1334> I wouldn't know where to start, I got libgl-mesa-dev amd gtkglext-dev
[04:15:40] <skinnypuppy1334> Have any other suggestions ?
[04:15:40] <jmkasunich_> those are probably 14AWG, 15 amps
[04:15:41] <cradek> skinnypuppy1334: put all the output on pastebin.ca
[04:15:56] <JymmmEMC> cradek: I wish I did
[04:16:05] <cradek> they're also 10', which is sometimes much nicer than 6'
[04:16:28] <JymmmEMC> Many just have thick jackets too, so it's hard to tell
[04:16:57] <skinnypuppy1334> http://pastebin.ca/482124
[04:17:05] <skinnypuppy1334> Thank you for taking a look at that
[04:17:35] <JymmmEMC> I have this VERY NICE enclosure and it even has an outlet in the front of it already, wanted to run the spindle thru it and a SSR inside.
[04:17:48] <ohiopctechDOTcom> wire current is waaaay under-rated for saftey :)
[04:17:56] <cradek> did you configure with --prefix?
[04:18:02] <ohiopctechDOTcom> i use cat5 for all kinds of stuff
[04:18:18] <jmkasunich_> ohiopctechDOTcom: I hope you don't use it for 120V line cords
[04:18:23] <skinnypuppy1334> user@user-desktop:~/gcam$ ./configure -prefix=/home/user/gcam
[04:18:27] <ohiopctechDOTcom> um no..
[04:18:27] <cradek> looks like your install directory (--prefix) is the same as your build directory
[04:18:37] <ds2> ohiopctechDOCcom: trying to avoid work hardening by keeping the wires red hot? ;)
[04:18:39] <skinnypuppy1334> am I missing one - ?
[04:18:44] <cradek> configure and build again without specifying --prefix
[04:18:47] <ohiopctechDOTcom> i compiled gcam fine on win and linux***
[04:18:55] <cradek> then it'll install in /usr/local and all work right
[04:18:57] <jmkasunich_> quit
[04:19:00] <ohiopctechDOTcom> i had to add a bunch of dep's tho
[04:19:03] <skinnypuppy1334> are the directories being the same ok ?
[04:19:03] <jmkasunich_> oops
[04:19:15] <cradek> no, that's an error
[04:19:19] <JymmmEMC> * JymmmEMC hands jmkasunich_ an /
[04:19:41] <jmkasunich_> actually, I didn't want to quit IRC, I wanted to quite halrun (in another window)
[04:19:51] <skinnypuppy1334> ok so use /usr/local or /usr/local/gcam ?
[04:19:56] <JymmmEMC> jmkasunich_: ok, heh
[04:20:02] <cradek> just ./configure
[04:20:03] <cradek> then, make
[04:20:07] <cradek> then, sudo make install
[04:20:16] <CIA-8> 03jmkasunich 07TRUNK * 10emc2/src/hal/utils/halcmd_commands.c: make message visible
[04:20:20] <skinnypuppy1334> no prob
[04:20:27] <cradek> then, gcam
[04:20:28] <cradek> :-)
[04:20:35] <cradek> I better get to bed, goodnight
[04:20:38] <jmkasunich_> there, maybe that will be the beginning of the end for linkpp
[04:20:49] <cradek> yay
[04:20:59] <skinnypuppy1334> Thank you cradek
[04:21:10] <ohiopctechDOTcom> i'd guess you could get away with using all the strands of cat5 togethere for each side of a 120v line...
[04:21:17] <ohiopctechDOTcom> ***dont try that at home
[04:21:24] <jmkasunich_> the insulation isn't rated for that voltage
[04:21:33] <JymmmEMC> It's pretty cool... the case already has a fuse holder, big 120VAC fan with grill guards inside and out, 120VAC outlet in front with indicator light, and has 4 8ohm 100W WW resistors nicely mounter.
[04:22:37] <JymmmEMC> ... a 12c molex connector on the front along with a illuminated push on/off power switch.
[04:23:14] <ohiopctechDOTcom> i been thinking about a lexan box for my driver and ps.
[04:23:20] <jmkasunich_> goodnight all
[04:23:23] <ohiopctechDOTcom> righ tnow it's still laying onmy desk
[04:23:26] <JymmmEMC> G'Night
[04:23:31] <ohiopctechDOTcom> night yo!
[04:25:41] <skinnypuppy1334> I didn't get an error from make nor sudo make install.. but gcam doesn't open it command not found.. Was anyone else following that conversation ?
[04:26:35] <ohiopctechDOTcom> cd to the install dir
[04:26:44] <ohiopctechDOTcom> then type gcam or sudo gcam
[04:26:47] <ohiopctechDOTcom> i think*
[04:26:52] <ohiopctechDOTcom> is that what your asking?
[04:27:26] <ohiopctechDOTcom> in your home directory/gcam/ ?
[04:27:47] <skinnypuppy1334> I'm in /home/user/gcam where the bins are
[04:27:56] <ohiopctechDOTcom> that works for me
[04:28:34] <skinnypuppy1334> user@user-desktop:~/gcam$ ./configure -prefix=/home/user/gcam

[04:29:57] <skinnypuppy1334> ? I did make, and sudo make install
[04:30:22] <ohiopctechDOTcom> ok so it installed to a different directory, right?
[04:30:29] <ohiopctechDOTcom> thats the source dir
[04:31:04] <skinnypuppy1334> Only used .configure with no --prefix that time
[04:32:52] <skinnypuppy1334> I found a /usr/local/gcam dir but typing gcam in that dir gives command not found
[04:34:13] <skinnypuppy1334> I have the subfolders bin, include, lib, samples, share... does it look like it is installed?
[04:38:30] <skinnypuppy1334> I did it all over, config --perfix /usr/local/gcam , then make, then sudo make install... but typing gcam gives me command not found.
[04:39:09] <ohiopctechDOTcom> i dunno, works for me... i followed the directions on the wiki.
[04:39:16] <ohiopctechDOTcom> try sudo ./gcam
[04:39:22] <SWPadnos> linux doesn't run programs in the cirrent directory by default. you have to explicitly add the "./" in front "./gcam"
[04:39:22] <ohiopctechDOTcom> worth a shot
[04:39:47] <skinnypuppy1334> that opened a gcam window ...
[04:39:54] <ohiopctechDOTcom> hmm...
[04:40:02] <ohiopctechDOTcom> AWESOME!
[04:40:09] <ohiopctechDOTcom> now load a sample file
[04:40:10] <ohiopctechDOTcom> ;)
[04:40:16] <skinnypuppy1334> Sweet, thank you for your help .
[04:41:54] <ohiopctechDOTcom> i'm going to start putting fun stuff out near the end of my driveway and filming it.. he will hit the stuff when he is drunk and not know it
[04:42:06] <ohiopctechDOTcom> GREAT VIDEO!
[04:42:21] <ohiopctechDOTcom> i watch it all the time here from my desk...
[04:42:38] <ohiopctechDOTcom> he, being my neighbor
[04:43:34] <skinnypuppy1334> Menu looks like it is pretty intuitive
[04:47:23] <skinnypuppy1334> This looks like a cool tool for EMC users, I'm looking at the G-code post for hub.cnc sample emc
[04:48:32] <ohiopctechDOTcom> if a completed open source conversational programming util comes up... then open source cnc will blow up!
[04:48:46] <ohiopctechDOTcom> blow up=catch on fast
[04:49:02] <skinnypuppy1334> yeah no doubt it would.
[04:49:22] <skinnypuppy1334> since i first looked at emc lathe has been added.
[04:49:48] <ohiopctechDOTcom> conversational is like giving away the candy for free tho... maybe nto a good idea
[04:49:56] <ohiopctechDOTcom> not*
[04:50:50] <skinnypuppy1334> I've been using dapper and edgy and 5. something ubuntu a while unless I needed to use .flv's from youtube on windows... with feisty that works with sound even
[04:52:19] <skinnypuppy1334> the .flv file support that is . Now that I have a VM configured I don't have to reboot to go over to mastercam and play round a while. I have a partiall functional X version with no file save and no post.. Toolpaths is still cool to play with on it though
[04:53:40] <skinnypuppy1334> I wonder if I could dig that active mastercam file out of the VMRAM or if it isn;t really a file but just a bunch of data at that point?
[04:55:50] <skinnypuppy1334> How can I run it without the ./ ?
[04:56:52] <eric_u> you have to use the export directive to set your path
[04:57:09] <eric_u> then you can add that line into your .bashrc
[04:57:34] <skinnypuppy1334> Could you run me through that realy quick ?
[04:57:47] <eric_u> or move the executable into usr/local/bin
[04:58:55] <eric_u> usually when you make install, it will put the executable into your path
[04:59:26] <skinnypuppy1334> user@user-desktop:/usr/local/gcam/bin$ sudo cp gcam /usr/local/bin
[04:59:35] <skinnypuppy1334> that got it, thank you
[05:00:29] <eric_u> where do you download gcam?
[05:01:30] <skinnypuppy1334> http://gcam.js.cx/index.php/Files
[05:01:40] <eric_u> thanks
[05:02:07] <eric_u> I think I may have broken their server though
[05:02:59] <skinnypuppy1334> thats interesting I can't browse to the manual page either
[05:04:37] <skinnypuppy1334> what happened to the server ???
[05:06:16] <eric_u> oh well, put it on my del.icio.us page, now I can find it without searching through pages of links on google
[05:08:26] <skinnypuppy1334> think the server will be back tonight?
[05:10:40] <skinnypuppy1334> the text is in google cache of the page atleast ...
[05:13:36] <skinnypuppy1334> Anyways thanks to all who helped me get this installed. It looks like a nice product!

[13:26:40] <jepler> good morning folks
[13:33:04] <cradek> hi
[13:33:25] <jepler> cradek: did you end up putting everything into that enclosure?
[13:33:32] <jepler> or if you didn't finish, is that still your plan?
[13:33:42] <cradek> not yet done, but it does look like it will all fit with some care
[13:40:47] <skunkworks> That is going to be cool. Threading at 200ipm? ;)
[13:41:15] <cradek> 50 or 60, yes - 200, no
[13:41:55] <Dallur> Martin: some progress, more to come over the weekend, I have been talking to the CandCNC guys and ordered a new THC, they also told me that it's customary to have debounce on all limit/home/probe signals when running plasma
[13:41:57] <skunkworks> The switch seems to work great. I need to goof around with making a sub to do the 'tool' change in your output from eagle..
[13:42:26] <cradek> skunkworks: I did that already - it's in the cvs
[13:42:30] <Dallur> Martin: So I will need to add that to the config to get rid of the erroneous signals
[13:42:45] <cradek> well I used g43, might not be what you want
[13:42:49] <skunkworks> right
[13:42:54] <skunkworks> close ;)
[13:43:08] <skunkworks> I might be able to tweek your code.. maybe
[14:12:32] <skunkworks> only 25mhz
[14:12:37] <skunkworks> oops
[14:59:35] <martin_lundstrom> Dallur: interesting
[15:05:13] <JymmmEMC> martin_lundstrom: Dallur isn't THAT interesting.
[15:08:23] <Dallur> JymmmEMC: I'm with you man, not that interesting at all
[15:08:45] <JymmmEMC> lol
[15:10:04] <skunkworks> interesting and odd are very close in company
[15:10:06] <martin_lundstrom> just kill me
[15:10:37] <JymmmEMC> skunkworks: You do realize you're in here as well, don't ya?
[15:11:10] <skunkworks> um - yah... I don't think anyone would dispute that I am odd
[15:11:50] <JymmmEMC> odd and 'are you out of your mind?!" are very close company.
[15:13:08] <JymmmEMC> ;)
[15:15:03] <JymmmEMC> Hey LawrenceG!
[15:18:09] <skunkworks> JymmmEMC: what are your thoughts on emc so far?
[15:19:23] <JymmmEMC> skunkworks: how so?
[15:21:05] <skunkworks> now that you have it pushing your machine around
[15:21:23] <JymmmEMC> haven't cut anything
[15:22:50] <skunkworks> and whos fault is that? HUH?
[15:23:04] <JymmmEMC> the stalling steppers
[15:23:20] <skunkworks> do you have your powersupply bits togather?
[15:23:31] <skunkworks> for your geckos?
[15:23:59] <JymmmEMC> Nope, still waiting for Mariss to respond to a few things.
[15:26:24] <skunkworks> we have had good luck with these http://cgi.ebay.com/PARKER-COMPUMOTOR-OEM650-DRIVE_W0QQitemZ150120822354QQihZ005QQcategoryZ71394QQrdZ1QQssPageNameZWD1VQQcmdZViewItem
[15:26:32] <skunkworks> * skunkworks muddies up the water
[15:29:31] <cradek> what is it?
[15:29:39] <JymmmEMC> stepper driver
[15:31:23] <JymmmEMC> Interesting... M2 option allows users to store programmed sequences in
[15:31:23] <JymmmEMC> nonvolatile memory
[15:33:20] <JymmmEMC> skunkworks: Have you bought from that seller before?
[15:36:27] <JymmmEMC> damn... 50,800 Steps/Rev
[15:36:41] <JymmmEMC> jumper selectable
[15:36:53] <JymmmEMC> oh, nm
[15:38:05] <cradek> "gear shift" is interesting
[15:39:40] <JymmmEMC> cradek: Sounds just like MAriss' step pulse generator
[15:40:47] <cradek> but you can turn it on and off
[15:41:07] <cradek> a suitable driver could give full resolution at low speed, plus fast jogs, all with software generated step pulses
[15:41:46] <JymmmEMC> cradek: Right below that, I see RS232c "slave drive" connection... serial controlled?
[15:42:37] <JymmmEMC> The 650 have home/limit switch inputs.... kinda cool.
[15:43:10] <SWPadnos> what are you looking at (with the "slave drive" connection)
[15:43:11] <SWPadnos> ?
[15:43:23] <JymmmEMC> http://www.compumotor.com/manuals/OEM/OEM350-650.pdf
[15:43:30] <SWPadnos> ah
[15:43:44] <JymmmEMC> pg 26
[15:43:59] <JymmmEMC> pg 33 in the viewer
[15:44:14] <SWPadnos> ok - I'm scanning the document now
[15:44:42] <JymmmEMC> OEM650X Inputs and Outputs
[15:45:16] <JymmmEMC> cradek: Could emc drive drives via paraport?
[15:45:26] <JymmmEMC> cradek: Could emc drive these via paraport?
[15:45:35] <cradek> sure they just take step/dir
[15:46:05] <JymmmEMC> ah, ok. the mention of serial confused me.
[15:46:53] <JymmmEMC> You may daisy chain up to 8 OEM650Xs.
[15:47:17] <skunkworks> sorry - was away. the 'X' has its own 'indexer' in it. We never used it.
[15:47:35] <skunkworks> we always used them as dumb step and direction drives.
[15:47:40] <SWPadnos> it looks like they want up/down output (figure 2-7, p 11)
[15:47:42] <jepler> see figure 2-7, showing step and direction on the db-style connector. looks like it is differential input.
[15:48:28] <cradek> I saw somewhere that those go right to optos, so it doesn't have to be
[15:48:41] <SWPadnos> ah, yes. I should have more coffee
[15:48:57] <skunkworks> they are up to 6 amp. iirc
[15:49:09] <SWPadnos> 7.5 up to 48V, 6.9 up to 75V
[15:49:47] <cradek> nice
[15:50:00] <SWPadnos> at least that's what the little table says. the text says 0.83-2.5 (low range) or 2.5-7.5 (high range)
[15:50:09] <skunkworks> you can usually if your patient get them for under 50$ on ebay.
[15:50:31] <SWPadnos> Id say that $38 each (with 2 available) is under $50
[15:50:36] <SWPadnos> and that's buy-it-now
[15:51:04] <skunkworks> the x ones you can remove the indexer and install some jumpers to get it back to a step/dir input.
[15:51:11] <cradek> singapore...
[15:51:14] <skunkworks> oops
[15:51:23] <skunkworks> no I have not bought from that seller
[15:51:36] <SWPadnos> $27 shipping
[15:51:41] <JymmmEMC> skunkworks: k
[15:52:45] <skunkworks> we probably have 8 or more... but we won't let them go :)
[15:52:51] <skunkworks> sorry
[15:54:59] <jepler> cradek: look again, that shows the internal optoisolators
[15:55:19] <cradek> what page?
[15:55:27] <jepler> 24
[15:56:08] <cradek> yeah we must be talking past each other
[15:56:26] <jepler> no surprise there
[15:56:31] <cradek> you said it needs differential signals, I said it doesn't because it's optos (which don't care where ground is)
[15:56:42] <cradek> what did I misunderstand?
[15:57:14] <jepler> nothing, probably
[15:57:25] <jepler> I think I'm the one who misunderstood
[15:57:42] <jepler> so an optoisolator can also function as a differential receiver? interesting.
[15:57:45] <JymmmEMC> differential?
[15:58:15] <jepler> JymmmEMC: "differential" transmission is a method that is more noise resistant.
[15:58:30] <jepler> let me see if wikipedia's got a good page on it
[15:58:37] <JymmmEMC> jepler: ah, requres differnet handling?
[15:58:55] <skunkworks> I ran these directly from a printer port for a while.
[15:59:08] <JymmmEMC> that seller has one X too same price
[15:59:25] <JymmmEMC> http://cgi.ebay.com/PARKER-COMPUMOTOR-OEM650X-M2-DRIVE_W0QQitemZ150120823285QQihZ005QQcategoryZ71394QQrdZ1QQssPageNameZWD7VQQcmdZViewItem
[15:59:26] <jepler> no pictures or diagrams unfortunately: http://en.wikipedia.org/wiki/Differential_signalling
[15:59:31] <SWPadnos> an opto isn't quite a differntial input, since it's unipolar. differntial signals generally have a significant deadband near 0V
[15:59:54] <skunkworks> like I say - the oem650x can be converted to a oem650 by replacing the doughter board with about 5 jumpers.
[15:59:56] <jepler> http://en.wikipedia.org/wiki/Image:RS-485_waveform.png
[16:00:09] <SWPadnos> so a broken differntial pair will register as "undetermined", but an opto will be 0
[16:00:11] <skunkworks> daughter
[16:00:15] <JymmmEMC> skunkworks: cool
[16:00:50] <jepler> notice how instead of one signal (referenced to ground) the value of the signal is defined by "is voltage A higher than voltage B"
[16:01:20] <SWPadnos> it's more like "is A >> B or is B >> A"
[16:01:43] <SWPadnos> "idle" is when they're too close to call
[16:02:22] <jepler> JymmmEMC: listen to SWPadnos, he knows better than me
[16:02:46] <SWPadnos> but I always recommend things that are too expensive, so listen to jepler too :)
[16:02:46] <JymmmEMC> jepler: It's all good, and over my head =)
[16:03:21] <JymmmEMC> LOL http://www.parkermotion.com/manuals/EMC/EMC_Install_C2.pdf
[16:04:42] <SWPadnos> oooh - we should have a "simulated lightning strike" HAL module :)
[16:05:27] <JymmmEMC> SWPadnos: http://cgi.ebay.com/New-OWON-PDS5022S-Portable-Color-Digital-Oscilloscope_W0QQitemZ300110416618QQihZ020QQcategoryZ104247QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[16:05:41] <SWPadnos> not that again?
[16:05:56] <JymmmEMC> :(
[16:06:02] <SWPadnos> heh
[16:06:16] <JymmmEMC> owondigital.com
[16:06:21] <SWPadnos> I also noticed last night that they're the same price at the manufacturer
[16:06:24] <skunkworks> dad just sent me that link :)
[16:06:39] <JymmmEMC> SWPadnos: cheaper if you consider $10 shipping from the mfg
[16:06:44] <SWPadnos> right
[16:06:51] <cradek> I recommend a first/only scope should have a CRT
[16:07:09] <SWPadnos> heh
[16:07:17] <cradek> that's probably just my prejudice though
[16:07:21] <skunkworks> first scope should be a nice B&K ;)
[16:07:37] <SWPadnos> I agree, if you're comparing to older or slower digital scopes
[16:08:04] <JymmmEMC> That seller has 3 of those drives, one being the X. Hmmmmm combine shipping ??? (doubtful)
[16:08:07] <SWPadnos> newer scopes, with fast update rates and "analog-like" controls, are far better than an analog scope
[16:08:26] <SWPadnos> JymmmEMC, I bet they could combine shipping. it simplifies their international paperwork
[16:08:34] <SWPadnos> s/could/would/
[16:08:55] <JymmmEMC> SWPadnos: Many HK shippers charge premium shipping to offset ebay fees.
[16:09:27] <SWPadnos> their shipping charges are in the ad: $27 (or 28) for one, but 2 Kg is $37 ...
[16:10:27] <JymmmEMC> $152 for 3 axis + customs
[16:10:33] <skunkworks> or ieco(sp) ;) that was my first scope.
[16:10:59] <jepler> SWPadnos: I assume this ebay digital scope isn't in the category you were just describing :-P
[16:11:00] <skunkworks> little 3" round tube
[16:11:11] <skunkworks> or maybe 2"
[16:11:11] <SWPadnos> I don't know, but probably not
[16:11:30] <JymmmEMC> I've never had to pay custom before, never a big purchase, how does that work?
[16:11:32] <SWPadnos> they are saving money in a couple of ways - assembly in China, plus using a DSTN LCD instead of high res TFT
[16:11:33] <jackc> jackc is now known as crepincdotcom
[16:11:40] <jepler> eek "Vertical resolution: 8 bit "
[16:11:49] <SWPadnos> that's normal for almost all digital scopes
[16:11:52] <jepler> really
[16:11:53] <SWPadnos> even the $25000 ones
[16:12:05] <SWPadnos> they increase resolution by averaging
[16:12:38] <SWPadnos> it's not physically possible to make a high speed scope that's also high resolution - you have to cool the converters waaaay down (like liquid nitrogen temps or lower)
[16:12:54] <JymmmEMC> at least it has a serial port =)
[16:13:10] <SWPadnos> and USB, I think
[16:13:22] <JymmmEMC> yeah, I'm just not fond of USB
[16:14:05] <JymmmEMC> has anyone ever paid customs fees?
[16:23:41] <skunkworks> I don't think I have
[17:03:12] <anonimasu> JymmmEMC: I have
[17:20:23] <tomp> custom fees are complex. begin at usgov/cagov and find the category the poruct belongs to, that code will lead you to an estimated tarriff. this is besides the importing cost ( air/water ) which is based on wight and size... refer to a shipper for that information. this is separate from the cost of shipping fromt he mfrctr to the port and from the port to you. that is often available in a package deal from the shipper. and there are fees
[18:57:08] <steve_stallings> steve_stallings is now known as steves_logging
[20:04:26] <cradek> JymmmEMC: I have - I got a bill in the mail later (this was DHL)
[20:05:40] <cradek> 'DHL worldwide express'
[20:05:52] <cradek> by some freak chance of nature, I have the invoice here
[20:08:21] <skunkworks> So I called meade and they are replacing the part that is broken.
[20:08:26] <anonimasu> hmm
[20:08:59] <cradek> * cradek kicks skunkworks over to that other channel
[20:09:23] <skunkworks> sorry
[20:09:28] <cradek> :-)
[20:09:32] <cradek> I used to do it all the time
[20:09:40] <skunkworks> <skunkworks> I just got a meade 90mm go-to scope for 90$ with a broken mount.
[20:09:51] <robin_sz> skunkworks, so when I get my 10" reflector all mounted up, you reckon on an EMC controlled starfinder?
[20:10:08] <robin_sz> ooh, tasty!
[20:10:29] <skunkworks> Funny you should mention that,, I had a dream that cradek was programming it to control a dish..
[20:10:58] <robin_sz> you dream about cradek?
[20:10:58] <cradek> the hard part would be the mounting
[20:10:59] <skunkworks> This is a pretty small scope. in the 200-400 dollar range 90mm
[20:11:02] <robin_sz> * robin_sz shudders
[20:11:32] <skunkworks> we have the club scope which is a 14 inch. but needs a bunch of work.
[20:11:37] <robin_sz> they cost a lot more than that over here
[20:11:54] <skunkworks> it is a maksutov-cassegrain
[20:12:18] <robin_sz> uh huh
[20:12:18] <skunkworks> cute little thing. make a great spotting scope also
[20:12:23] <robin_sz> so quite short
[20:12:42] <skunkworks> very - about a foot with a 1250mm effective focal lenght
[20:13:33] <skunkworks> but the go-to should be fun to play with - it also has a satellite library
[20:14:40] <robin_sz> with auto tracking?
[20:14:44] <skunkworks> yes
[20:15:25] <skunkworks> http://cgi.ebay.com/BRAND-NEW-Meade-DSX-90-Self-Guided-Telescope_W0QQitemZ170109627759QQihZ007QQcategoryZ74928QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[20:15:30] <skunkworks> that is it
[20:17:14] <robin_sz> very nice, and cheap
[20:17:53] <skunkworks> yes. expecially if I do get the replacement mount from meade. so far so good - they sent a pickup tag.
[20:18:23] <skunkworks> I could fix it - but if they are going to replace it - I have no problem with that :)
[20:23:11] <robin_sz> is that the same as an ETX90?
[20:26:28] <skunkworks> I don't know my meade models
[20:49:56] <ds2> did I ever mention I so very much hate libtool?!
[22:40:29] <alex_joni> good night all
