[02:09:50] <Loetmichel> mornin'
[04:13:35] <cncMaker> hi all how do i apply a patch
[04:13:41] <cncMaker> i cloned git
[04:14:57] <cncMaker> do i need to "git am --sigoff xxx.patch" first then in src "./autogen.sh"
[04:17:56] <Vq> Something like that.
[04:21:32] <Vq> If the git command is not complaining it should do what you want.
[05:06:10] <automata_> hello
[05:06:26] <automata_> hi psha
[05:08:42] <psha[work]> hi
[05:09:46] <automata_> I found out about max number of modules of a particular type and it is greater than 64. But I have not narrowed down to the exact count...
[07:05:01] <Jymmm> 3:00
[07:05:15] <Jymmm> 2.34
[07:06:32] <Jymmm> 2.16
[07:07:52] <Jymmm> 2.01
[07:08:22] <awallin> huh, what's going to happen at 0:00 ??
[07:08:43] <Jymmm> I go POOF!
[07:08:53] <awallin> ok.
[07:09:03] <cevad> There will be aurora in 45 minutes.
[07:09:08] <Jymmm> Battery Time Remaining
[07:09:47] <Jymmm> 2.22
[07:12:03] <Jymmm> 2.11
[07:13:59] <Vq> Jymmm: End of the warranty?
[07:14:30] <Jymmm> Vq: End of the World as we know it!
[07:14:47] <Vq> D:
[07:15:52] <Jymmm> I found out recently that Macs dont condition the battery if it's just kept at your desk plugged in. So to condition the battery it's suggested that you drain the battery once a month.
[07:16:33] <Vq> I see
[07:16:55] <Jymmm> Since I have timestamps on each entry on irc, I'm just using the clint as a Q&D chart to gauge the battery life over time.
[07:17:13] <Jymmm> 2012-02-07 04:56:08 Jymmm: 2.34
[07:17:13] <Jymmm> 2012-02-07 04:57:26 Jymmm: 2.16
[07:17:14] <Jymmm> 2012-02-07 04:58:46 Jymmm: 2.01
[07:18:36] <Jymmm> 1.53
[07:28:19] <Jymmm> 1.44
[07:30:55] <Jymmm> 1.35
[07:36:34] <Jymmm> 1.27
[08:18:54] <joe9> mikegg: what is the accuracy of your cnc machine? can it do 15 mil traces?
[08:31:18] <joe9> mikegg: I will be back on the irc after some time. need to fix something on my box.
[09:29:09] <mrsun> is there documentation of the linuxcnc tooltable format somewhere? :)
[09:29:20] <jthornton> the manual has that
[09:29:28] <jdhNC> there isn't much to it.
[09:29:35] <jdhNC> isn't there a header line?
[09:31:26] <jdhNC> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ToolTable
[09:32:29] <mrsun> jdhNC, yeah but doesnt state how an actual tooltable file looks like =)
[09:32:52] <jthornton> open it up
[09:33:11] <mrsun> do not have one :P
[09:33:26] <mrsun> can someone send me one or pastebin one? :9
[09:33:58] <jthornton> it's just a text file with a header line
[09:34:34] <jthornton> ops no header it seems
[09:34:35] <jthornton> T1 P1 D0.125000 Z+0.511000 ;1/8 end mill
[09:34:36] <mrsun> jthornton, yes ... but can someone pastebin one so i can see what stuff is named etc inside of the text file? :P
[09:34:47] <jthornton> I just did
[09:34:52] <mrsun> just straight lines like that? :)
[09:35:23] <jdhNC> just white space separated columns
[09:35:40] <jthornton> much better to look at the manual than wiki http://linuxcnc.org/docview/2.5/html/gcode/tool_compensation.html#_tool_table_a_id_sec_tool_table_a
[09:35:49] <jdhNC> you don't have a sample one on your install?
[09:36:03] <jthornton> well that is 2.5, what are you using
[09:36:40] <jthornton> 2.4 http://linuxcnc.org/docview/html/gcode_tool_compensation.html#r1_2
[09:55:11] <Gromits> I have a Glade togglebutton and associated led. When I toggle the button, I see it's state change in "show hal config". But the the led only changes color if I click the button twice.
[10:04:55] <Gromits> The button is acting as if I have to push it twice to toggle between each state, but in hal it is toggling each time it is pressed (as it should).
[10:10:40] <Gromits> skunksworks: have you played any more with glade (specifically toggle buttons)?
[10:18:48] <mikegg> joe9: what is the distance between traces? the smallest end mill I have is 35 mils.
[10:19:12] <joe9> mikegg: some of my traces have 15 mil between them.
[10:19:53] <mikegg> joe9: heh, in that case definitely not
[10:20:02] <joe9> mikegg: these pcb milling cnc machines, they drill, etch the traces and also cut the pcb to size? do they do all of that?
[10:20:54] <joe9> or, do they need different machines for the task. the pcb thickness is either 1/16inch or lesser.
[10:21:05] <mikegg> not sure about cutting to size. You would have to put something sacrificial underneath the PCB
[10:21:28] <mikegg> same with drilling, I suppose
[10:21:56] <syyl> you need that for drilling too, yes
[10:22:03] <joe9> ok, thanks.
[10:22:18] <syyl> doubleside tape and a piece of wastematerial
[10:22:25] <syyl> i use polyurethane foam
[10:23:06] <joe9> I need etching on the pcb cobber side and some not-through holes on the other side.
[10:24:09] <syyl> then you need a way to index tha pcb after flipping over
[10:24:27] <joe9> ok, just wanted to make sure that it is possible.
[10:31:24] <JT-Shop> I hate it when you analyze a mistake and make a mistake about where the mistake was and turn around and make the same mistake over again. :/
[10:32:00] * JT-Shop has some real purdy white oak firewood now
[10:32:55] <Gromits> JT-Shop: are you familiar with Glade togglebutton object?
[10:36:28] <JT-Shop> nope
[10:36:43] <Gromits> ok, thx.
[10:41:44] <joe9> mikegg: do you know any places in/around Atlanta that can mill pcb's for 15 mil traces?
[10:42:11] <joe9> mikegg: preferably someone that does not charge me an arm and a leg.
[10:55:33] <joe9> mikegg: the t-tech models have a minimum trace (in the specification) of 5 mils. Is your controller off? why is it that yours can do only 35 mils?
[11:00:57] <joe9> this looks so cool: http://www.taigtools.com/cmill.html, but, the price is also pretty cool (being sarcastic). Anyone own this puppy?
[11:07:48] <mikegg> I dunno, it probably could. But I don't have any 15 mil end mills.
[11:07:49] <jdhNC> http://www.ebay.com/itm/200679844257
[11:11:38] <mikegg> joe9: have you talked to the guys at freeside Atlanta?
[11:11:54] <mikegg> it's a hackerspace on the southside
[11:12:06] <joe9> mikegg: yes, they did not know of any. they were a little unhelpful, imho.
[11:12:07] <mikegg> they have a new member meeting tuesday nights
[11:12:17] <mikegg> really?
[11:12:33] <mikegg> I would have thought one of those guys would have a PCB mill
[11:12:39] <mikegg> huh
[11:12:41] <joe9> yes, I read about their meeting on Tue nights.
[11:13:08] <mikegg> did you call T-Tech and ask them if they provide PCB milling as a service?
[11:13:16] <joe9> seemed more like a closed org to me, atleast, this specific hackerspaces' attitude appeared that way to me.
[11:13:24] <joe9> mikegg: i have not. will do. thanks.
[11:14:16] <joe9> mikegg: do you know of anyone who built a cnc at home with precision of <= 10 mils?
[11:14:32] <joe9> is it practical?
[11:24:52] <jdhNC> I would consider < 1mil hard, <10mils fairly routine
[11:27:08] <joe9> jdhNC: thanks.
[11:27:57] <joe9> jdhNC: i am browsing the cnczone pcb milling archives about how to go about building one. curious, how long does one take to build for a beginner?
[11:29:08] <jdhNC> a day to a year, depending on how good you are and what you have laying around and how much cash you have to spend.
[11:29:27] <joe9> "a day" really?
[11:29:38] <jdhNC> if you buy most of it premade
[11:29:48] <joe9> maybe, if I buy the cnc machine and use the linuxcnc controller, correct?
[11:29:49] <jdhNC> entire frame, drives, etc
[11:29:57] <cradek> I think jdhNC is saying that those kinds of questions are unanswerable
[11:30:10] <jdhNC> that was a better answer :)
[11:30:17] <joe9> cradek: jdhNC: ok, thanks. sorry for the bother.
[11:30:33] <jdhNC> no bother, just no realistic way to guess.
[11:36:20] <Loetmichel> re @ home
[11:37:14] <Jymmm> Could someone use one of these for $40? http://www.platt.com/platt-electric-supply/Holemaking-Punches-Spade-Bits-Keyway-Punch/Greenlee/720/product.aspx?zpid=24976
[11:43:50] <JT-Shop> can't think of why I would want two of them...
[11:57:36] <sirhoax> anyone run vmware w/ubuntu realtime kernel, and able to interface their cnc-controller?
[11:57:54] <cradek> that won't work
[11:58:02] <sirhoax> er. ;[
[11:58:17] <cradek> you can't get realtime inside vmware no matter what kernel you run
[11:58:28] <sirhoax> any work around for 64bit ubuntu ?
[11:58:48] <sirhoax> having issues installing it ATM.
[11:59:08] <FinboySlick> sirhoax: Well, I don't think you need 64bit for anything EMC related.
[11:59:09] <cradek> the linuxcnc kernel and install is 32 bit
[11:59:19] <sirhoax> "Install a normal Ubuntu 10.04 (only 32-bit is supported for realtime) "
[11:59:28] <sirhoax> k.
[11:59:35] <cradek> in the big picture, what are you trying to do?
[11:59:39] <sirhoax> will just have to set it up on another machine. no biggie
[12:00:07] <sirhoax> loaded up all the dependencies ! heh.
[12:00:12] <sirhoax> oh well will have to go back and remove them.
[12:00:14] <sirhoax> heh.
[12:01:33] <sirhoax> its probably better off having another machine dedicated for controlling the CNC.
[12:01:47] <sirhoax> so will just go that route.
[12:02:04] <cradek> sounds smart to me, that's what I like to have as well
[12:02:39] <FinboySlick> My machine is so fast it needs a beowulf cluster of EMC.
[12:03:03] <sirhoax> got RhinoCAD/CAM running on vmware. working alright for the most part.
[12:03:16] <sirhoax> website said it wouldn't work, but it works fine.
[12:03:48] <sirhoax> beowulf ..!
[12:03:49] <FinboySlick> sirhoax: I wouldn't be surprised if it ran under Wine too.
[12:04:13] <sirhoax> FinboySlick, from reading on the internet ppl tried and couldn't get it working.
[12:04:17] <FinboySlick> sirhoax: If it does, you'll have better opengl.
[12:04:24] <FinboySlick> OK.
[12:04:45] <sirhoax> well for machining operations, not going full blown 3d rendering. heh.
[12:04:49] <FinboySlick> It's apparently possible to do SolidWorks 2011 under Wine.
[12:07:03] <sirhoax> give me another excuse to load up linux on another machine.
[12:07:06] <sirhoax> fine by me. heh.
[12:07:31] <sirhoax> how large is the software when unpacked? from the cd.
[12:07:48] <sirhoax> want to try this on a small compact-flash-card.
[12:07:49] <FinboySlick> You sould be fine with 2G
[12:08:03] <sirhoax> nice..! :-)
[12:08:11] <cradek> I'd guess >2G but <4G
[12:08:24] <Jymmm> JT-Shop: Heh, and you were the first one I thought of too.
[12:08:35] <cradek> 8G for a build environment etc
[12:08:47] <cradek> only guesses
[12:09:18] <sirhoax> k.
[12:09:27] <Jymmm> GF gone, time to play!!!!!!!
[12:09:46] <jdhNC> you are a little bit off, huh.
[12:09:57] <Jymmm> Like a G6....
[12:09:58] <sirhoax> got these cheap SATA-to-CFcard converters.
[12:10:07] <sirhoax> want to mess around with it. see how it works.
[12:10:18] <Jymmm> jdhNC: Nah, I can play my music LOUD =)
[12:10:25] <FinboySlick> sirhoax: Don't use a cheap CF card if you expect it to last.
[12:10:26] <jdhNC> send her over here.
[12:10:29] <sirhoax> apparently the industrial compact flash can handle >6,000,000 write cycles.
[12:10:40] <sirhoax> FinboySlick, yea i hear ya.
[12:10:43] <FinboySlick> sirhoax: You'll get Jymmm started.
[12:10:51] <sirhoax> heh.
[12:11:19] <sirhoax> load it into ramdisk ! :)
[12:11:24] <sirhoax> tmpfs.
[12:11:28] * sirhoax snickers
[12:11:45] * Jymmm needs a bigger sub
[12:13:25] <FinboySlick> Jymmm: I have a pair of Altec Lansing A7 in storage if you'd like.
[12:13:59] <Jymmm> FinboySlick: I was thinking more like 18" JBL with 1000W amp
[12:14:16] <FinboySlick> Jymmm: At least you didn't say Bose.
[12:14:23] <sirhoax> new method of machining? with BASS..! heh.
[12:14:31] <Jymmm> Well, 901's are good
[12:14:59] <sirhoax> made some interesting mid-range boxes out of foam.
[12:15:03] <Jymmm> If you have the acoustic designed room for them
[12:17:22] <Jymmm> sirhoax: I hope that was concrete foam
[12:17:32] <Jymmm> or a lot of structural support.
[12:17:43] <Loetmichel> Jymmm: i liked the turbosound TCs118... but isnt for small rooms because of the horn... needs about 3meters to "assemble" the base
[12:17:56] <sirhoax> just layered 2" pink foam you find at homedepot.
[12:18:08] <Loetmichel> roofmate?
[12:18:09] <Jymmm> sirhoax: O_o
[12:18:09] <sirhoax> carved out and coated.
[12:18:38] <sirhoax> worked alright for mid-range.
[12:18:51] <sirhoax> they were only 6" speakers.
[12:18:52] <Jymmm> so would a cardboard box, but...
[12:19:06] <sirhoax> fiberglassed it.
[12:19:18] <sirhoax> thing was strong once you coated it.
[12:19:29] <Loetmichel> Jymmm: actually that isnt so bad as it sounds. i made some speaker enclosures out of K-line once (12mm PU-foam laminated with 120g/m^2 paper both sides)
[12:19:40] <Jymmm> It needs to be dense
[12:19:57] <Jymmm> like 2" MDF dense
[12:20:04] <Loetmichel> very strong and weights nothing: got the resonance of the enclosure walls somewhre where noone will hear them ;-)
[12:20:05] <Jymmm> ok maybe 1"
[12:21:01] <Loetmichel> was measured surprisingly linear
[12:21:08] <Loetmichel> t6he speakers
[12:21:48] <Jymmm> I knew an Acoustical Engineer that would win contests hands down year after year.
[12:22:42] <Jymmm> You dropped a bomb on me...
[12:25:59] <sirhoax> yea with 11 chain driven alternators. :)
[12:26:08] <sirhoax> not conventional
[12:34:44] <sirhoax> is anyone using emc2 w/reprap?
[12:38:32] <bill20r3> I did, a little, just to jog around a mendelmax.
[12:38:39] <bill20r3> but I never sorted out the temperature handling stuff.
[12:40:59] <sirhoax> k.
[12:41:44] <bill20r3> I never found a really clean way, the most practical seems to be just using the existing arduino to manage the temps
[12:42:03] <bill20r3> although you could go a bit back and just have it report the raw values, then do the PID in emc2
[12:45:50] <sirhoax> what software are you using to set-up the machining op?
[12:46:09] <sirhoax> is it full as in design, post?
[12:46:39] <sirhoax> want to build a machine eventually. just have a lot of other stuff on my plate this year.
[12:46:41] <bill20r3> I'm not using emc2 on the mendelmax any more, I just went with a ramps setup.
[12:46:59] <bill20r3> although I'd love to use emc2, with it's good trajectory planning and such.
[12:48:11] <sirhoax> so you import a dxf and setup the code, or you build the 3d model and code in the same software?
[12:49:37] <bill20r3> oh, you mean for the printing toolchain? you make an STL in whatever you prefer, then feed it to your slicer(skeinforge, sfact, slic3r), then send that to the controller with host-software(Pronterface, ReplicatorG, RepSnapper)
[12:50:52] <sirhoax> k. just curious, like i said down own a machine ATM.
[12:51:37] <bill20r3> Sure. it's reasonably mature now, you can likely get something working for $500-$600
[12:57:14] <sirhoax> k.
[12:57:25] <sirhoax> yea wanted to build my own.
[12:57:28] <sirhoax> save some money.
[12:58:21] <jdhNC> nifty toy, can't see a practical use given the material constraints
[13:00:17] * bill20r3 shrugs.
[13:00:24] <bill20r3> you must not have looked very close.
[13:01:40] <Gromits> Anyone know if there is a "Touch Off All"" capability in 2.5? I know I can set up a pyvcp/glade button to do a g10 l2 p1 x0 y0 z0, but there was a discussion at one point about adding it to Axis...
[13:09:17] <mrsun> on a lathe, the carriage would be the Z, and inout X right ? :)
[13:12:32] <jdhNC> Z is generaly the axis going in to the work
[13:14:43] <mrsun> even on a lathe? :)
[13:14:54] <mrsun> i thought it was the axis that goes parallel with the spindle
[13:16:58] <joe9> i came across this method of using laser for pcb milling? I hear that someone even used a dvd-rw laser to do one.
[13:22:51] <jdhNC> right
[13:36:36] <jdhNC> oh, I said Z above... sorry.
[13:38:52] <mrsun> ahh so Z is the carriage then and X is the in out action =)
[14:26:48] <joe9> is this a good way to start learning about diy cnc machine: http://buildyourcnc.com/latest.aspx
[14:27:00] <joe9> curious, if there are any other better tutorials out there.
[14:28:11] <cradek> > No, not that wood silly, the piece of scrap wood
[14:28:16] <cradek> seems likely to me
[14:29:21] <cradek> > One more marriage saving advice, clean up after yourself. Wood gets displaced from the material onto all that beautiful furniture.
[14:29:44] <archivist> "Build the ugly CNC to build the Pretty CNC" very true
[14:29:48] <cradek> wow, 36 pages
[14:30:52] <cradek> I bet it was a lot of work to put together these videos etc.
[14:30:54] <archivist> joe9, also depends what you want to make with the machine
[14:31:07] <joe9> archivist: pcb milling, drilling and cutting.
[14:31:14] <joe9> around 10 mils in accuracy
[14:31:19] <cradek> then this machine is pretty useless for you
[14:31:36] <jdhNC> do you have more money or time?
[14:31:37] <cradek> you need better than 10 mils for pcbs. that's about the width of traces.
[14:31:49] <joe9> cradek, yes.
[14:32:03] <cradek> then maybe I don't know what you mean by "10 mils in accuracy"
[14:32:04] <joe9> jdhNC: yes, I do. enough to do a good job, I think.
[14:32:34] <joe9> cradek: I have traces of 15 mils. I need a cnc that can do that.
[14:32:58] <joe9> cradek: not sure how that translates to "in accuracy terms"
[14:33:15] <cradek> if your machine cuts +-10mils from the desired location and you try to cut traces of 15 mils width, some will not be there at all, some will be 35 mils wide
[14:33:49] <joe9> cradek: you are correct. sorry about that.
[14:34:14] <cradek> for pcbs, you need zero backlash, high speed spindle, and very little cutting force and rigidity
[14:34:29] <archivist> a rule of thumb is make/measure an order of magnitude better, therefore accuracy should be 1 mil for 10mil
[14:34:30] <joe9> cradek: jdhNC: do you know of any diy tutorials for pcb milling cnc machines?
[14:34:37] <cradek> no
[14:34:52] <joe9> gecko servo's seem good.
[14:34:53] <cradek> but I have milled many circuit boards
[14:35:11] <cradek> gecko's servo drives are step/dir which is a crappy match for linuxcnc, which can do better
[14:35:28] <joe9> cradek: any words of advice?
[14:35:31] <cradek> may as well use steppers - they are MUCH simpler and cheaper for a low power machine
[14:35:41] <cradek> yes, up a few lines :-)
[14:36:08] <joe9> gecko steppers then..
[14:36:08] <jdhNC> http://timeguy.com/cradek-files/cnc/pcb/stepdriver2.jpg
[14:36:18] <jdhNC> ^^^ that looks pretty damned good to me.
[14:36:40] <cradek> yes that's an excellent milled pcb, best you can hope for
[14:36:43] <joe9> jdhNC: yes, it looks good.
[14:37:13] <cradek> also http://timeguy.com/cradek-files/cnc/pcb/dscn6119.jpg
[14:37:30] <cradek> soic pads, traces between 0.1" pitch pads
[14:37:35] <jdhNC> what angle bits are you using?
[14:37:42] <cradek> the thinktink ones
[14:37:52] <joe9> cradek: what is the size of those small traces?
[14:37:53] <jdhNC> same one for the rubout parts?
[14:38:08] <cradek> no, I just use a flat endmill for that
[14:38:11] <cradek> 1/16
[14:38:21] <archivist> cradek, has jmk finished his pcb mill yet?
[14:38:28] <cradek> joe9: .008-ish
[14:38:54] <joe9> cradek: that is pretty impressive. .008 mm, I presume.
[14:39:00] <cradek> maybe .012 on the big board
[14:39:36] <joe9> cradek: sorry, 0.008 mil, it appears.
[14:44:10] <joe9> cradek: are there more details (bom,etc) . I am checking this page out. but, would be good to have more details.http://timeguy.com/cradek/cnc
[14:46:37] <cradek> nope
[14:46:52] <joe9> any thoughts on this: http://www.engadget.com/2006/06/29/how-to-build-your-own-cnc-machine-part-1/
[14:48:47] <archivist> looks a bit toy ish
[14:52:32] <joe9> archivist: any better suggestions that can guide me?
[14:53:02] <jdhNC> joe: http://www.cnczone.com/forums/pcb_milling/123650-pcbs_weve_milled.html
[14:53:10] <jdhNC> check the pics and what they used to make them.
[14:53:24] <joe9> jdhNC: thanks.
[15:11:33] <joe9> mikegg: just spoke with the T-tech folks and they say that a QC 5000 is $9000/-. He tells that refurbished systems go for >$9,000/-. That is probably a '0' more, for my purposes.
[15:11:48] <joe9> kinda surprised that they are priced at so much.
[15:12:05] <joe9> when the tiag tools are around $3000'ish.
[15:12:29] <cradek> you can get a vmc for that money
[15:12:53] <Jymmm> I got some 1/4-20 threaded rod and MDF you can have =)
[15:13:23] <jthornton> I paid 5k for my BP Discovery 308 VMC and it ran out of the box
[15:13:23] <archivist> joe9, or build from parts in the scrap box(shed)
[15:13:25] <joe9> Jymmm: for making a pcb milling machine? would love to buy them from you, if they help.
[15:13:43] <jdhNC> sarchasm doesn't carry well.
[15:14:02] <syyl> stil going for pcb milling?
[15:14:10] <joe9> sorry, did not have my "sarcasm detection" cap on..
[15:14:15] <Jymmm> joe9: do you have access to a mill/lathe?
[15:14:15] <jdhNC> joe: you in atlanta?
[15:14:18] <joe9> syyl: that is the plan.
[15:14:34] <syyl> i did it
[15:14:36] <joe9> Jymmm: I have a harborfreight mill, but, that seems pretty useless.
[15:14:38] <syyl> i do it still soemtimes
[15:14:39] <joe9> jdhNC: yes.
[15:14:41] <syyl> my advice
[15:14:50] <joe9> syyl: yes, please. I need advice.
[15:14:53] <syyl> let em be made by a professional pcb maker :)
[15:15:02] <Jymmm> joe9: Maybe some acme rod and make your own anti-backlash nuts
[15:15:05] <jdhNC> I have an extra cnc router frame that is of dubious accuracy, but definitely good for learning
[15:15:27] <Jymmm> jdhNC: define accuracy of it
[15:15:39] <jdhNC> no way to quantify
[15:15:56] <syyl> fast, perfect accuracy, doubleside with vias is no problem, ...
[15:15:58] <Jymmm> guestimate?
[15:16:13] <jdhNC> a few thou
[15:16:19] <joe9> syyl: do you have any details on how you made it? bom?
[15:16:27] <Jymmm> jd +/- ?
[15:16:34] <syyl> took my milling machine, a v-shaped single point cutter
[15:16:38] <syyl> and went for it :P
[15:16:51] <syyl> http://dl.dropbox.com/u/24396704/port4_1.jpg
[15:17:01] <syyl> http://dl.dropbox.com/u/24396704/port4_2.jpg
[15:17:28] <joe9> syyl: what is the size of those thin traces?
[15:17:41] <joe9> syyl: name and design of the milling machine?
[15:17:42] <syyl> a bit smaller than 0,1mm
[15:17:56] <syyl> convert it to imperial measurement yourself ;)
[15:17:59] <joe9> 4 mil, wow, cool.
[15:18:14] <joe9> 1 mm ~ 38 mil.
[15:18:36] <syyl> http://dl.dropbox.com/u/24396704/2012-01-22_17-54-50_793.jpg
[15:18:39] <syyl> thats the machine
[15:18:55] <syyl> no flimsy router :P
[15:20:07] <joe9> i cannot read the machine model/name. What is it?
[15:20:17] <syyl> its a deckel g2 engraver from 1928
[15:20:33] <syyl> retrofittet with ballscrews, steppers, glas scales and emc2
[15:20:54] <joe9> ok, thanks. I need to find something more practical that I can find.
[15:21:09] <syyl> but, as i said, i prefer a professional pcb manufacturer
[15:21:56] <syyl> much better quality of the pcb

[15:50:20] <mikegg> I love it. "made in Taiwan (not China)"
[15:56:40] <bill20r3> I suppose that's somewhat better.
[16:07:24] <A2Sheds> most of the worlds semiconductors are fabbed in Taiwan at TSMC
[16:24:02] <mikegg> for some reason, I feel like I need a couple of these
[16:24:04] <mikegg> http://www.ebay.com/itm/ALLEN-BRADLEY-INVERTER-DUTY-AC-SERVO-MOTOR-TLY-A2540-HJ62AA-5K-RPM-90mm-NEMA-34-/380409358502?pt=LH_DefaultDomain_0&hash=item58922a28a6#ht_1690wt_1397
[16:24:54] <mikegg> I wonder if that clamping mechanism could be fashioned into a decent three jaw chuck
[16:25:32] <mikegg> probably not
[16:32:33] <JT-Shop> take off the gripper and put a chuck on would be the easy way, grippers are not very sturdy usually
[16:53:19] <joe9> mikegg: that cnc machine on ebay is pretty cool.
[17:16:31] <JT-Shop> I too love "Made in Taiwan (not China)"
[17:18:30] <skunkworks_> pcw_home: Yay!
[17:22:52] <skunkworks_> http://www.cnczone.com/forums/product_announcements_manufacturer_news/147002-new_product_release_5i25_pci.html
[17:25:18] <Valen> damn pcw_home thats awesome
[17:25:51] <Valen> makes a game changing price difference for using the whole mesa chain if it can be done easily
[17:28:26] <JT-Shop> awesome
[17:29:07] <bill20r3> $64, nice.
[17:29:19] <bill20r3> so probably $99'ish in singles?
[17:36:42] <skunkworks_> not that much... singles is $89
[17:41:18] <JT-Shop> just a smidgen over $200 with a daughter card and cable
[17:43:00] <skunkworks_> yep
[17:43:08] <mikegg> cool
[17:43:30] <skunkworks_> although - a cheap break outboard for starters would get you a nice setup initally
[17:43:52] <skunkworks_> You would not need one with a watchdog timer...
[17:44:24] <mikegg> arduino would do that, no?
[17:44:33] <mikegg> oh, *not need
[19:02:57] <jdhNC> $71 for 5+
