[00:17:27] <Optic> moo
[00:31:37] <Optic> i'm trying to think of cool things to cut out of cardboard
[00:32:35] <dareposte> fractals?
[00:40:00] <jmkasunich> origami?
[00:40:04] <jmkasunich> paper airplanes?
[00:41:37] <jmkasunich> funny: http://www.youtube.com/watch?v=1RV_peLE2qQ&feature=related
[00:46:26] <eric_unterhausen> http://www.youtube.com/watch?v=ej3KSfVU5aw
[00:46:36] <jmkasunich> Optic: http://www.youtube.com/watch?v=ej3KSfVU5aw
[00:46:44] <jmkasunich> heh
[00:47:29] <eric_unterhausen> I hope those guys a hacktactular.to are working on that
[00:57:51] <dareposte> is that some sort of diffraction grid under the laser?
[00:57:58] <dareposte> i always wondered how they kept it from cutting through the table
[00:59:35] <toastydeath> the laser tables i've seen dump into water?
[01:00:01] <toastydeath> now i wonder the same thing.
[01:08:31] <dareposte> dump into water?
[01:13:46] <toastydeath> instead of sitting on a solid bed, the ones i've seen sit on rods or little spikes?
[01:13:52] <toastydeath> the workpiece
[01:14:01] <toastydeath> and underneath is a big tub of water
[01:14:32] <dareposte> oh
[01:14:34] <toastydeath> but the only laser tables i've seen are like "we're cutting six inches of steel"
[01:14:45] <dareposte> yeah
[01:15:02] <dareposte> that would be fun to watch
[01:18:47] <Optic> i found a t-rex model on the forum that I'm trying to turn into valid gcode
[01:19:34] <Optic> are there any good free tools?
[01:20:03] <dareposte> freemill
[01:20:11] <Optic> that's probably a FAQ
[01:20:12] <Optic> ;)
[01:20:29] <dareposte> what format is it in?
[01:20:36] <DanielFalck> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
[01:20:45] <Optic> dxf
[01:22:14] <Optic> and I'm on a mac, natively :P I have an ubuntu VM
[01:22:24] <Optic> i've been looking at and tweaking files in QCAD which seems quite good
[01:22:30] <dareposte> i've never actually ran code from freemill, but i did do some backplotting and it looked like it would work pretty well. very easy to do with dxf
[01:22:48] <dareposte> oh
[01:23:49] <Optic> i can install a windows VM if I need to but I don't really want to :)
[01:24:46] <DanielFalck> try dxf2gcode on the link I posted
[01:26:04] <dareposte> yeah if you're running linux there are probably better utilities
[01:26:38] <dareposte> what wattage laser are you using?
[01:26:59] <dareposte> oh you didn't actually say you were using a laser did you, i just assumed
[01:27:30] <Optic> it's a 25 watt co2
[01:27:48] <Optic> i've tried the dxf2gcode, it makes broken arcs from that file and axis whines about it
[01:28:02] <DanielFalck> ok
[01:28:13] <Optic> dareposte: http://www.youtube.com/watch?v=JNg943u_r60
[01:29:01] <DanielFalck> I'm using HeeksCAD now, but there's a lot more involved in the installation
[01:32:12] <Optic> gcnccam makes almost empty gcode :P
[01:34:52] <dareposte> Optic: What thickness will 25w cut? Have you tried yet
[01:35:03] <dareposte> nice project
[01:35:03] <Optic> it can cut acrylic nicely
[01:35:13] <Optic> and I've been cutting stuff out of corrugated cardboard
[01:35:16] <Optic> it won't touch steel
[01:35:31] <Optic> should do nice things to balsa or other soft woods
[01:35:35] <eric_unterhausen> DanielFalck: have you ever tried to make lugs?
[01:35:49] <DanielFalck> eric_unterhausen: no
[01:35:58] <DanielFalck> eric_unterhausen: how about you?
[01:36:23] <eric_unterhausen> thinking about it, was that your fork crown I saw at NAHBS?
[01:36:29] <DanielFalck> yes
[01:36:47] <DanielFalck> and the drop outs, and seat stay plugs
[01:36:49] <eric_unterhausen> looked good
[01:36:52] <DanielFalck> thanks
[01:36:58] <DanielFalck> you were there then?
[01:37:09] <eric_unterhausen> I wish, pictures on the internet for me this year
[01:37:20] <DanielFalck> I didn't make it either
[01:46:09] <Optic> i guess I should install some Windows ;)
[02:16:37] <Optic> wow, i'm failing miserably at this :P
[02:17:53] <jack000> hellow
[02:18:19] <eric_unterhausen> hi
[02:18:42] <jack000> need some help with home switch wiring :]
[02:19:20] <eric_unterhausen> use wire?
[02:19:34] <jack000> any idea how large the pullup resistor has to be?
[02:19:42] <eric_unterhausen> what kind of system?
[02:19:50] <jack000> normally open
[02:19:54] <eric_unterhausen> 1k-10k is usual
[02:20:14] <jack000> ok, I'll try 10k first to be safe :]
[02:20:21] <eric_unterhausen> 1k is plenty
[02:21:04] <jack000> parallel port uses 5v logic right?
[02:21:16] <eric_unterhausen> possibly, who knows on motherboards
[02:22:06] <jack000> wonder if I could burn out the mobo if I supply 5v and it expects 3..
[02:22:24] <eric_unterhausen> probably not, but I always use a bob, why gamble?
[02:22:39] <eric_unterhausen> I'm sure the mobo is 5v tolerant
[02:22:59] <jack000> I bought one but I suspect it's broken. running bare right now..
[02:23:13] <eric_unterhausen> why broken? what brand?
[02:24:15] <jack000> dunno, bought off ebay. Some of the outputs simply don't work - outputs low even when the parallel port gives high
[02:26:02] <eric_unterhausen> that's why I went pmdx and cnc4pc
[02:27:14] <jack000> yeah, you really can't tell with ebay. hope he'll give me a refund..
[02:29:31] <jack000> alright, I guess I'll try 5v with 2k or something. thanks
[02:29:45] <eric_unterhausen> 2.2k is cheaper
[02:30:15] <eric_unterhausen> someday I'll figure out why they did that
[03:50:41] <Ito-Brazil> Hello ALL: someone knows about a GPL software that do the mesting pieces?
[03:51:11] <Ito-Brazil> I mean, less material loses (2D only is OK)
[03:53:33] <eric_unterhausen> lots of free nesting software listed on google, don't know about gpl
[03:54:15] <Ito-Brazil> for linux? Really free, or trial/shareware?
[03:54:32] <eric_unterhausen> interesting question, probably for windows
[03:55:51] <eric_unterhausen> found a reference on an email list that said to come here and ask :)
[03:55:57] <Ito-Brazil> pyuke! Window$? I´m out lol
[03:58:25] <Ito-Brazil> email list?
[03:58:43] <eric_unterhausen> I closed it, no info anyway
[03:58:43] <Ito-Brazil> I know this website since emc1 hahahhaha
[03:59:19] <Ito-Brazil> oke Thanks anyway dude, see ya guys!
[08:18:23] <Jack> aaahhh!! I was so close to being done..
[08:18:35] <Jack> anyone still here?
[10:29:02] <micges> good morning all
[10:29:40] <micges> cvs server seems down here
[11:06:41] <micges> cvs ok now, were some problems with europe<->america connection
[11:36:28] <MrSunshine> is emc core bound to the kernel in linux in anyway?
[11:40:11] <MrSunshine> ahh the rtapi is :/
[11:46:34] <BigJohnT_> morning micges
[11:46:46] <BigJohnT_> BigJohnT_ is now known as BigJohnT
[12:30:04] <roell> hi
[13:10:38] <toastydeath> hey
[16:54:40] <alex_joni> tetris anyone? http://sovietrussia.org/f/src/tetoris.swf
[17:07:21] <skunkworks> yikes
[17:14:31] <toastydeath> oh man now i want a pretzel from the mall
[17:20:20] <jepler> "how to lose at tetris" http://www.geom.uiuc.edu/java/tetris/tetris.ps
[17:28:47] <Paragon27> Hello All... It's been a while...
[17:32:53] <Paragon27> I am currently attempting to configure a 415/240v 3 phase suds pump to run at 240v 3 phase. The motor is a 6 wire plus 1 earth type. It is currently wired as a star (Y) but I need to wire it as delta (for 240) the problem is that it has no wire diagram. How can I tell which wires should be linked together?
[17:33:42] <jmkasunich> right now, three wires are connected together, right?
[17:33:52] <jmkasunich> and the other three are free, for input?
[17:33:53] <Paragon27> jmkasunich: Yep
[17:34:02] <Paragon27> Indeed....
[17:34:03] <jmkasunich> any labels on any wires?
[17:34:11] <Paragon27> No
[17:34:16] <jmkasunich> ok, here's the procedure
[17:34:44] <jmkasunich> label the three wires that are connected together, as 11, 21, and 31 (doesn't matter which is which)
[17:34:50] <jmkasunich> then unmake that connection
[17:34:53] <Paragon27> ok
[17:35:11] <jmkasunich> use an ohmeter to find the other end of each winding, and label them 12, 22, and 23
[17:35:16] <jmkasunich> oops
[17:35:20] <jmkasunich> 12, 22, and 32
[17:35:39] <jmkasunich> first digit identifies winding, 2nd digit identifies which end of the winding
[17:36:03] <jmkasunich> then connect 12 to 21, 22 to 31, and 32 to 11
[17:36:10] <Paragon27> Arhh thats the problem all the leads from the star cables buzz out to the indivudaul leads at 31 ohms
[17:36:11] <jmkasunich> those three connections become your input terminals
[17:36:27] <jmkasunich> that's because you haven't un-made the star connection
[17:36:44] <Paragon27> jmkasunich: I have...
[17:36:58] <jmkasunich> I'm confused
[17:37:03] <Paragon27> ok ...
[17:37:20] <jmkasunich> you have 6 wires, and you measure 31 ohms between _every_ possible pair?
[17:37:44] <Paragon27> take 11 and it shows 31ohms on 12 22 23
[17:37:54] <Paragon27> 21 shows the same
[17:38:09] <jmkasunich> so all six wires are connected together somewhere inside the motor?
[17:38:13] <Paragon27> as does 31 even though I have disconnected them from the start ... ?
[17:39:00] <Paragon27> I guess so but it should not be as the motor is a dual voltage (it has this on the name plate)
[17:39:55] <jmkasunich> label the wires 1-6, make a chart with 1-6 down the side, and 1-6 across the top, make the 36 resistance measurements and write them down
[17:40:12] <Paragon27> ok
[17:40:13] <jmkasunich> then look for meaningull patterns
[17:40:37] <jmkasunich> make sure you don't lose track of which wires were originally connected together at the star point
[17:41:06] <jmkasunich> ohms can identify winding (we hope) but not polarity - the original star point is the key to that
[17:41:16] <MrSunshine> how much deos the core of emc depend on the linux kernel ?
[17:41:22] <MrSunshine> how portable is it :)
[17:41:35] <jmkasunich> 1, 2, 3 should be the star point wires, 4, 5, 6 should be the ones that were originally the input leads
[17:41:53] <Paragon27> jmkasunich: Sure thing Im off to the shed now. Thank jmkasunich
[17:41:55] <jmkasunich> MrSunshine: that is not a simple question
[17:42:09] <BigJohnT> is it unusual to have just 6 leads on a three phase dual voltage motor?
[17:42:23] <jmkasunich> BigJohnT: EU motors are different than US motors
[17:42:26] <Paragon27> Not in the UK BigJohnT
[17:42:31] <jmkasunich> we have 240/480, which is a 2:1 ratio
[17:42:46] <jmkasunich> they have 240/415, which is sqrt(3):1 ratio
[17:43:00] <Paragon27> The motor was made in 1954 btw ...
[17:43:03] <jmkasunich> so they use three windings, and connect them in either wye or delta
[17:43:04] <BigJohnT> ok
[17:43:56] <jmkasunich> we use 6 windings, three permanently in wye (with the wye point buried), and either connect the other three in wye and parallel both sets (240), or connect the other three in series with the original wye (480V)
[17:45:27] <jmkasunich> MrSunshine: large parts of EMC2 use RTAPI - you can refer to rtapi.h to see what it provides, and if you are sufficiently motivated, you could write your own version of rtapi for some other OS
[17:45:47] <jmkasunich> smaller parts of EMC (drivers and such) can and do use other bits of the linux kernal and infrastructure
[17:46:02] <jmkasunich> for example the mesa drivers use the linux firmware loading infrastructure
[17:46:11] <MrSunshine> hmm
[17:46:13] <alex_joni> and some other parts don't use linux infrastructure/kernel at all
[17:46:16] <alex_joni> and could easily be ported
[17:46:30] <MrSunshine> that sucks :)
[17:46:43] <jmkasunich> what do you want to port to?
[17:46:59] <alex_joni> jmkasunich: nah, it sucks, not worth the trouble
[17:47:15] <MrSunshine> jmkasunich, haiku :)
[17:48:28] <jmkasunich> gotta go, bbl
[20:03:51] <DanielFalck> jepler: would you like to add this one to your list of emc related feeds:http://heekscnc.blogspot.com/
[20:04:11] <DanielFalck> he's writing an open source cam program that runs under linux
[20:05:43] <alex_joni> DanielFalck: ever seen google reader?
[20:05:56] <DanielFalck> no I haven't
[20:06:22] <alex_joni> it's nice for RSS feeds
[20:08:13] <jepler> DanielFalck: added
[20:08:18] <DanielFalck> great
[20:08:32] <DanielFalck> by the way, he has pocketing with islands work pretty well
[20:11:24] <jepler> cool
[20:25:07] <Shizuo> USB?
[20:25:38] <Shizuo> Yes?
[20:25:57] <alex_joni> Firewire
[20:26:06] <Shizuo> Where?
[20:26:48] <alex_joni> India
[20:26:56] <Shizuo> No EMC?
[20:27:30] <alex_joni> Shizuo: is this a riddle?
[20:28:44] <Shizuo> I feel confused?
[20:29:18] <alex_joni> I think you do
[20:29:36] <DanielFalck> Shizuo: what is your original question?
[20:29:52] <Shizuo> USB?
[20:30:05] <DanielFalck> how about a complete question
[20:30:17] <alex_joni> Universal Serial Bus?
[20:30:28] <Shizuo> Yes!
[20:30:32] <Shizuo> EMC + USB?
[20:30:39] <alex_joni> Shizuo: no
[20:31:12] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Emc2HardwareDesign#USB
[20:31:47] <Shizuo> Can me USB?
[20:31:50] <Shizuo> Code C yes
[20:32:14] <alex_joni> you can try.. no idea where you would start though
[20:32:27] <Shizuo> Me plz need thx
[20:33:07] <Shizuo> You USB me, work need
[20:33:53] <alex_joni> Shizuo: http://translate.google.com/translate?prev=hp&hl=en&u=http%3A%2F%2Fwiki.linuxcnc.org%2Fcgi-bin%2Femcinfo.pl%3FEmc2HardwareDesign&sl=en&tl=pt
[20:34:35] <Shizuo> Oh god, you guys are so nice
[20:34:40] <Shizuo> Anyway, thanks
[20:34:56] <Shizuo> I was thinking of changing the bit-banging lpt driver to accomodate my USB board
[20:35:01] <Shizuo> What do you think of it?
[20:35:20] <alex_joni> do you have any plans how fast it needs to work?
[20:36:47] <Shizuo> I was thinking of decoding the step commands using emc-side software
[20:37:00] <Shizuo> Then translating it to the motion protocol used by the board
[20:37:07] <Shizuo> It's a board with 4 PID channels for DC motors
[20:37:16] <alex_joni> emc2 as it is, doesn't need to have step commands
[20:37:38] <Shizuo> How can I plug into the motion API
[20:37:38] <alex_joni> the basic output from emc2 are positions
[20:37:39] <Shizuo> ?
[20:37:45] <Shizuo> Oh
[20:37:52] <Shizuo> Will I need to mess around with RT crap?
[20:37:56] <alex_joni> those can either go to "step generators" or to "custom hardware drivers"
[20:38:01] <alex_joni> either way, yes
[20:38:04] <Shizuo> Or I can just use plain Linux?
[20:38:38] <Shizuo> Can I make EMC output motion commands?
[20:38:59] <alex_joni> with a certain amount of hacking, maybe
[20:39:24] <alex_joni> Shizuo: this scenario has been greatly discussed lately
[20:39:45] <alex_joni> some parts are explained on that page, some have been on the mailing list emc-users and emc-developers
[20:39:48] <Shizuo> Direct motion commands would be awesome
[20:39:53] <alex_joni> you can find archives linked from linuxcnc.org
[20:40:09] <Shizuo> I don't like the idea of running the interpreter inside an RT kernel
[20:40:15] <Shizuo> Just because the motion code is glued to it
[20:40:27] <alex_joni> the interpreter doesn't run in RT
[20:40:37] <Shizuo> It runs inside the same kernel
[20:40:49] <Shizuo> Meaning: you need an RT machine to interpret G-Code
[20:40:50] <alex_joni> not for emc2
[20:40:55] <alex_joni> no, you don't
[20:40:55] <Shizuo> Is it client-server?
[20:41:16] <alex_joni> well.. the interpreter is linked with the task controller
[20:41:21] <Shizuo> Linked how?
[20:41:22] <alex_joni> both run as a userspace process
[20:41:30] <Shizuo> But inside the same machine
[20:41:33] <alex_joni> yes
[20:41:37] <Shizuo> Aka:same kernel
[20:41:53] <alex_joni> I don't understand "same kernel"
[20:42:30] <Shizuo> Well, I have expensive motion control boards here
[20:42:31] <alex_joni> they do run as a linux process, so it's on one machine
[20:42:40] <alex_joni> the GUI can run on a different machine
[20:42:46] <Shizuo> Yet I will need an RT system just to get an interpreter to output positions to me
[20:42:48] <alex_joni> and the IO controller on a different one
[20:42:54] <alex_joni> no, you don't
[20:43:05] <Shizuo> I can use it on plain Linux then?
[20:43:07] <alex_joni> task controller and interpreter don't need RT to run
[20:43:11] <alex_joni> yes, you can
[20:43:15] <Shizuo> What needs RT to run?
[20:43:23] <alex_joni> only the motion controller uses RT usually
[20:43:33] <Shizuo> Oh, I don't like emc's motion controller
[20:43:37] <alex_joni> but emc2 can be compiled in "simulation" mode, where it all runs userspace
[20:43:46] <alex_joni> Shizuo: that's too bad :)
[20:43:48] <Shizuo> Using a board with a PCI bus to control motors is insane
[20:44:19] <Shizuo> It's like using a gasoline-powered automobile to control an inverted pendulum
[20:44:53] <cradek> that is among the strangest assertions I've ever heard
[20:46:37] <Shizuo> cradek: Having a PCI bus between your PID/whatever code and the controlled variable is WRONG
[20:46:57] <Shizuo> It's good for laboratory situations, such as National Instrument boards used for education
[20:47:12] <Shizuo> But for a real controller it IS like using a four-stroke engine to power an inverted pendulum controller
[20:47:15] <Shizuo> Lots of lag
[20:47:25] <Shizuo> And use of excessive complexity to achieve a simple task
[20:47:59] <cradek> sorry you don't like the architecture that works so well for us - but what is your point really? are you asking for help with something?
[20:48:14] <Shizuo> So what it works well for you?
[20:48:21] <Shizuo> Does it mean it's perfect?
[20:48:25] <Shizuo> Error-free?
[20:48:34] <Shizuo> Is it the best solution, engineering-wise?
[20:48:39] <Shizuo> Just because it works "well" for you?
[20:48:44] <cradek> are you just trolling?
[20:48:47] <Shizuo> No
[20:48:54] <Shizuo> You're being defensive for nothing
[20:48:59] <Shizuo> Don't force people to agree with you
[20:50:15] <cradek> you're being agressive for nothing - why call the platform "insane" and "WRONG"? what's the goal you're working toward here?
[20:50:28] <Shizuo> Oh, I see
[20:50:32] <Shizuo> The typical zealot attitude
[20:50:42] <Shizuo> "Oh noes, criticism, let's question his presence here"
[20:50:47] <cradek> ad-hominem
[20:50:54] <Shizuo> Works for almost every single open-source community
[20:51:01] <Shizuo> I'm here because I want to
[20:51:18] <Shizuo> And doing interactive control behind heavy buses is wrong
[20:51:33] <Shizuo> Go back (or go for the first time) to college if you missed proper education
[20:51:39] <cradek> hahaha
[20:51:56] <alex_joni> Shizuo: you're slowly stepping out of line
[20:52:13] <Shizuo> No, I'm not
[20:52:18] <alex_joni> yes you are
[20:52:23] <Shizuo> I hate when open-source people direct hate towards criticism
[20:52:26] <alex_joni> no need to be rude to people you don't know
[20:52:43] <Shizuo> It's not even a stereotype anymore, it has turned into bitter reality
[20:52:45] <alex_joni> it's one thing to be critical about a design, that's your call
[20:52:53] <Shizuo> alex_joni: He was rude first, so I don't really care
[20:52:58] <alex_joni> no he wasn't
[20:53:06] <Shizuo> alex_joni: He mostly told me to "stfu or go away" after hearing criticism
[20:53:14] <jmkasunich> you are quite free to design a machine controller the way you think it should be designed
[20:53:29] <Shizuo> That's what I am doing
[20:53:33] <Shizuo> I came here to see if EMC changed
[20:53:41] <Shizuo> And alex told me some differences from 1 to 2
[20:53:57] <alex_joni> I did?
[20:53:58] <cradek> you're either trolling or sadly inept at playing well with others... your criticisms so far are only assertions (usually based on mistaken assumptions about EMC) with no relevant support, and ad-hominem attacks.
[20:54:30] <jmkasunich> EMC's architecture uses the PC to do realtime motion control. If you don't like that, fine. That doesn't make it stupid, or insane, or anything else. Any more than your approach is stupid or insane or anything else.
[20:54:37] <Shizuo> I don't need to detail my criticisms
[20:54:41] <cradek> and that's just silly - I can't determine whether you are working toward an interesting goal or not
[20:54:52] <cradek> you certainly do if you want to affect others' opinions
[20:54:53] <Shizuo> It's you who needs to respect them or ask for more detail
[20:54:59] <Shizuo> I don't want to affect
[20:55:01] <cradek> and if you don't care about that, why come here?
[20:55:02] <Shizuo> I was just chatting
[20:55:13] <jmkasunich> sorry, but in any technical discussion, you DO need to support your assertions with facts
[20:55:20] <Shizuo> Get out of your parent's basement, you're too harsh on people
[20:55:28] <cradek> hahaha
[20:55:38] <jmkasunich> Shizuo: you know nothing about cradek or anyone else here
[20:55:46] <alex_joni> jmkasunich: now where did you get the wrong impression it's a technical discussion
[20:56:06] <jmkasunich> I was giving him the benefit of the doubt
[20:56:21] <jmkasunich> my doubt is rapidly turning to certainty
[20:56:22] <Shizuo> Oh god, open-source people
[20:56:25] <Shizuo> Living at basements
[20:56:28] <Shizuo> No money on pockets
[20:56:30] <cradek> ad-hominem
[20:56:31] <Shizuo> Never doind real business
[20:56:36] <Shizuo> Can't handle criticisms
[20:56:50] <cradek> troll troll troll lalalalala
[20:56:51] <Shizuo> Now I know why mainstream and open sores never get close
[20:57:00] <cradek> * cradek waves happily
[20:57:10] <jmkasunich> if he is the mainstream, I don't want to get close
[20:57:14] <jmkasunich> I might get some if it on me
[20:57:21] <alex_joni> heh
[20:57:25] <cradek> wow that ... something
[20:57:30] <cradek> er, that was ... something
[20:58:20] <cradek> I get the feeling someone's gonna go make a smokin' blog or youtube comment
[20:58:58] <DanielFalck> on a more positive note....I have found a fun way of generating gcode with some of Dan Heek's libraries using python
[20:59:51] <cradek> I keep hearing about heeks cad - I ought to go read about it
[21:00:06] <DanielFalck> it's pretty cool
[21:01:24] <alex_joni> cradek: http://code.google.com/p/heekscnc/
[21:01:40] <cradek> oooooo
[21:02:03] <DanielFalck> http://pastebin.ca/1368379
[21:02:07] <DanielFalck> gives me:
[21:02:15] <DanielFalck> http://imagebin.org/42325
[21:02:45] <DanielFalck> sorry about the big blue thing in the opengl screen (I was playing earlier)
[21:02:49] <cradek> what is the blue?
[21:02:50] <cradek> ah
[21:03:01] <DanielFalck> I have a kurt vise drawn in the axis screen
[21:03:06] <DanielFalck> sort of...
[21:03:15] <cradek> cool
[21:03:28] <DanielFalck> anyway, heeks has it going on
[21:03:46] <DanielFalck> surfacing, contouring, pocketing
[21:04:17] <DanielFalck> I did a bunch of engraving with it last weekend for some cub scout plaques
[21:04:53] <DanielFalck> my only complaint is that it seems to get kind of slow because he's using a bunch of xml in between processes for the gcode
[21:05:29] <DanielFalck> and just for the record....I don't live in a basement :)
[21:05:47] <cradek> ha
[21:05:54] <alex_joni> who does?
[21:06:01] <alex_joni> ;)
[21:06:07] <DanielFalck> open source people right ?....
[21:06:22] <jmkasunich> I bet Shizuo does
[21:06:24] <alex_joni> right, and they are also 15 years old
[21:06:34] <alex_joni> at most
[21:06:45] <cradek> actually I used to live in my parents' basement
[21:07:10] <jmkasunich> how many decades ago?
[21:07:30] <cradek> 2
[21:07:34] <DanielFalck> I used to rent a basement apartment years ago
[21:08:06] <DanielFalck> anyway....http://code.google.com/p/heekscnc/wiki/Capabilities
[21:08:14] <JymmmEMC> I don't know if anyone cares or not, but if you get annoyed by the extra stuff when you use the built-in google search dialog, Edit /usr/lib/firefox-addons/searchplugins/google.xml and remove all Param lines except <Param name="q" value="{searchTerms}"/>
[21:09:12] <jepler> JymmmEMC: good tip, thanks
[21:09:24] <JymmmEMC> =)
[21:09:38] <cradek> DanielFalck: any quick hints about how to build heekscad/cnc?
[21:09:59] <cradek> oh, I found something
[21:10:01] <DanielFalck> it should be on the wiki somewhere, but you have to have Opencascade
[21:10:05] <DanielFalck> then HeeksCAD
[21:10:06] <JymmmEMC> Be sure to shut down FF BEFORE editing that file
[21:10:26] <DanielFalck> join #cam and we can chat more there
[21:16:21] <cradek> still working on building it...
[21:17:11] <DanielFalck> I think the one of the neat things about the project is that the contouring, pocketing etc.. is split into different projects and can be used outside of heekscnc
[21:17:22] <alex_joni> cradek: there's a wiki page
[21:17:24] <DanielFalck> like actually from a text editor
[21:17:28] <alex_joni> but you need open cascade iirc
[21:17:35] <cradek> alex_joni: yep I found it, thanks
[21:20:26] <fenn> cradek: IMHO the "compiling for debian" instructions are much better (even if you're using ubuntu) http://code.google.com/p/heekscad/wiki/CompilingForDebian
[21:21:26] <fenn> the instructions for installing heeksCNC stuff are not complete - you need to copy area.so and kurve.so and actp.so from their respective build folders to HeeksCNC/
[21:21:27] <cradek> fenn: I got it going - I got the general idea from the instructions. I skipped all the pointyclicky stuff of course
[21:22:20] <cradek> yes I like the instructions better - thanks
[21:22:57] <cradek> I somehow already have the HAVE_LIMITS define without that edit
[21:25:18] <DanielFalck> bbl
[21:26:35] <fenn> er, yeah i accidentally committed it an i guess nobody noticed/cared
[21:30:51] <cradek> this could sure use some packaging...
[21:36:17] <cradek> I havebuilt area.so and actp.so, but have not found a pointer to kurve yet
[21:36:45] <cradek> oh it's inside the heekscnc checkout but built separately
[22:22:47] <Paragon27> jmkasunich: Got that suds pump working....
[22:31:46] <JymmmEMC> Man I wish there was a xref for transformers
[22:34:21] <alex_joni> good night all
[22:48:04] <jmkasunich> Paragon27: good to hear it
[23:22:33] <Paragon27> jmkasunich: I was being an idiot ... I was checking with a meter and had not realised that the ends of the power lead were touching as it was hanging over the desk.... lol
[23:49:14] <Paragon27> Chaps I have a question with regards to coolant.
[23:51:17] <Paragon27> Today I removed the coolant pump from my mill which had coolant in the resovour before i bought it. The coolant is a light brown colour. This coolant got all over my hands and lower arm. What kind of coolant could this be?
[23:52:36] <Paragon27> The reason i ask is that I just looked up coolant on google and it list various health hazards etc....
