[02:37:30] <pingufan> Good morning. My harddisk in my CNC mill died and now I want to replace it with a SD-card -> IDE Converter or a CF-card -> IDE converter plus card. Is ths working fine? All data (CNC jobs) come over Ethernet, I only have the system on the card. What is the minimum size the card must have?
[02:41:42] <pingufan> Is 2GB SD-Card or CF-Card sufficient to install and run Linux-CNC?
[02:50:13] <Loetmichel> mornin'
[08:46:39] <amaldo> Anyone from Europe around? I would like to get a small 3 axis CNC machine for light robotics work, and was looking at the Tormach, but it seems they don't have CE markings. So any other options? Or has anyone been able to import one?
[08:51:15] <jdh> Syil claims CE
[08:51:42] <jdh> http://www.syilamerica.com/product_docs/MachineDocs/X4/X4_series_CE_Certification.pdf
[08:51:58] <amaldo> jdh: thanks for the info. Will look into the brand.
[08:52:37] <jdh> I could engrave "CE" on my G0704 and send it to you.
[08:53:19] <amaldo> jdh: :) If that works for the import officers, why not?
[09:59:34] <tjb1> Power is back :D
[09:59:57] <jdh> cool
[10:00:02] <jdh> crank up the a/c :)
[10:01:16] <tjb1> I woke up and heard the ac was like no way, am I dreaming?
[10:02:12] <tjb1> http://sphotos-a.xx.fbcdn.net/hphotos-snc7/304707_4343706232174_1033791622_n.jpg
[10:02:22] <tjb1> Thats not too far away from me
[10:03:25] <jdh> humidity was 92% when I left this morning
[10:03:57] <tjb1> I slept on the kitchen floor
[10:05:19] <tjb1> I am stiff.
[10:09:29] <Tom_itx> funny how the wind pushes the lightening as well as the tornado
[10:11:36] <tjb1> Im just surprised we got power back this fast
[10:12:11] <Tom_itx> i was out over 2 weeks during an ice storm once
[10:12:27] <Tom_itx> generally hail/tornados don't take quite as long
[10:12:37] <Tom_itx> maybe 2 to 4 days
[10:12:57] <tjb1> We use to lose power when it rained before then ran the new lines
[10:12:59] <Tom_itx> we're generally one of the last to get power back
[10:13:43] <amaldo> Tom_itx: tjb1: Just out of curiosity, where are you guys located? I live in Munich, and there has not been one power outage in the building in the 7 years that I've been here.
[10:13:55] <Tom_itx> central US
[10:13:56] <tjb1> clearfield, pa
[10:13:57] <syyl> amaldo?
[10:13:59] <syyl> munich?
[10:14:14] <syyl> im near regensburg...
[10:14:19] <amaldo> syyl: Yes? In Germany.
[10:14:32] <amaldo> syyl: Cool. I'm working at the TUM (Technische Universitaet Muenchen)
[10:15:17] <amaldo> Tom_itx: tjb1: Amazing. How big are the cities? Here all hell would break loose if there was no power for more than a couple of hours.
[10:15:31] <Tom_itx> 500k
[10:15:44] <tjb1> I dont live in a city
[10:16:44] <tjb1> 20 houses on my 4 mile road
[10:17:06] <amaldo> tjb1: I was expecting that... Then it takes longer for the companies to fix things, they first have to reach you.
[10:17:23] <amaldo> Tom_itx: How was it when you had no power for 2 weeks? Sounds like a zombie apocalipse. :)
[10:17:32] <tjb1> It was nothing around here but I didnt drive far enough to see where it was
[10:17:38] <syyl> sounds like a lot of candles ;)
[10:17:47] <tjb1> Tom_itx: at least when the power goes out in the winter you can sleep
[10:18:44] <amaldo> syyl: Do you have a machine running linuxCNC? I'm new to this (coming from EE, robotics) and I am curious to see which machines people have in Europe.
[10:18:56] <syyl> of course :)
[10:19:08] <syyl> i run a retrofitted deckel g2 engraving machine..
[10:19:19] <syyl> linuxcnc, mesa and closed loop steppers
[10:20:02] <amaldo> syyl: closed-loop steppers? Do they have an optical encoder on the axe? Sounds like a well done setup.
[10:20:17] <syyl> a linear scale on the axis
[10:20:28] <syyl> i am pretty happy with it
[10:20:30] <syyl> :)
[10:21:09] <syyl> http://gtwr.de/werkstatt_panorama.jpg
[10:21:11] <amaldo> syyl: Is your machine older than 90 years?
[10:21:18] <syyl> on the very right you can see the machine
[10:21:32] <syyl> mh, 1927 if i remember correct..
[10:21:48] <amaldo> syyl: I was almost right. What a jewel!
[10:21:52] <tjb1> tile floor in the workshop eh
[10:22:03] <syyl> its like hell, tjb1
[10:22:12] <syyl> horrible to keep clean
[10:22:15] <amaldo> syyl: I guess you posted to madmodder before. Google found the machine there.
[10:22:19] <tjb1> Did you lay it? :P
[10:22:28] <syyl> of course :D
[10:22:32] <tjb1> That sucks doesnt it
[10:22:33] <syyl> yes, amaldo
[10:22:38] <syyl> a bit :D
[10:22:52] <amaldo> syyl: Niiice setup. :)
[10:23:17] <syyl> thank you :)
[10:24:33] * amaldo hopes to someday have a workshop like that at work.
[10:25:18] <syyl> :)
[10:25:28] <syyl> i want to expand some day :D
[10:25:37] <syyl> more room and serious machinery..
[10:25:40] <amaldo> syyl: and what do you do with such nice tools? Are you contracting?
[10:25:48] <syyl> naa, just for hobbie
[10:26:09] <syyl> model engineering and random tinkering :D
[10:26:17] <syyl> more the later..
[10:28:01] <amaldo> syyl: awesome. Just so you know, you are better equipped that most labs here at the university doing robotics. We often have to hire shops for parts.
[10:28:14] <syyl> what? realy?
[10:28:29] <syyl> the workshop at our university is very well equiped
[10:28:35] <syyl> with 10 machinists or so
[10:28:55] <amaldo> syyl: We are doing robotics in the computer science faculty, that is the source of the problem. The people over at mechanical engineering have it good.
[10:29:06] <syyl> ah, ok
[10:29:12] <syyl> that explains something :D
[10:29:53] <amaldo> syyl: yep, but something very similar happens also to the people over at electrical engineering, they have a shop for the whole faculty, so it is hard to get parts done.
[10:30:33] <amaldo> syyl: and the funny/sad thing is that most people doing robotics are either in CS or EE.
[10:30:52] <syyl> :(
[10:32:12] <tjb1> Are the mounts on the back of a monitor standard?
[10:32:28] <syyl> yes
[10:32:34] <syyl> the four-bolt-pattern?
[10:32:41] <syyl> google for vesa mount
[10:32:42] <tjb1> Yes and the opening
[10:34:00] <tjb1> http://d3d71ba2asa5oz.cloudfront.net/43000231/images/et1515l%20(4).jpg
[10:34:09] <tjb1> That is standard syyl ^
[10:34:39] <syyl> :)
[10:35:02] <tjb1> Thanks
[10:35:08] <tjb1> Off to find a mount now :)
[10:35:15] <syyl> make one!
[10:35:30] <syyl> heavy steel, plasmacutter, some welding.. :D
[10:35:41] <jdh> or buy one dirtcheap from monoprice.com
[10:35:54] <syyl> thats the easy way :D
[10:37:15] <jdh> $8-10 for a mount... sure.
[10:37:43] <tjb1> Anything like this jdh? http://www.ebay.com/itm/LCD-TV-Monitor-Tilt-Articulating-Arm-Wall-Mount-Bracket-15-17-19-21-22-23-1E9-/360397146995?pt=US_TV_Mounts_Brackets&hash=item53e9580b73#ht_3067wt_1165
[10:38:46] <jdh> sure, but about the same price.
[10:40:05] <tjb1> I want one that fits the 75x75 only so it will fit in the hole
[11:13:03] <joe9> i am deciding on which step block to buy from here http://www.te-co.com/Default.aspx?CategoryID=PG1012 It appears that I should buy the biggest available.
[11:13:17] <joe9> Is there any reason to go for the smaller size step block?
[11:13:40] <joe9> I am thinking of 40104, though for my purposes now 40102 will suffice.
[11:13:55] <joe9> other than cost, is there something else that goes into this decision?
[11:15:53] <cradek> they have a minimum height - see the range it shows in the table
[11:16:02] <cradek> so no, the biggest available is not necessarily what you want
[11:16:16] <cradek> you probably want a full clamping set, which will have a nice useful variety
[11:17:15] <cradek> http://www.te-co.com/Machinist+Clamp+Kits-C-PG1005-C-.aspx
[11:17:47] <cradek> get the kit that matches your T slot size (which is proportional to your machine size) and you'll have a useful set for most tasks
[11:18:25] <joe9> cradek, my T-slot size is 6mm and I am getting the t-slots separately, as I could not find a vendor with clamping kits for a taig.
[11:18:39] <joe9> cradek: i am checking up on the minimum height and they do not seem to have one.
[11:19:00] <joe9> the range is the max height availability
[11:19:07] <joe9> when vertical on horizontal.
[11:19:38] <joe9> cradek: i am not questioning what you said just trying to understand where/what the minimum height is.
[11:20:41] <joe9> "Height Adj. Range" is what they are calling it.
[11:20:47] <joe9> the more the better, it seems.
[11:21:11] <joe9> and all the step blocks have steps of 1/16inch or 1/8 inch (the other way).
[11:22:44] <alex4nder> joe9: http://littlemachineshop.com/products/product_view.php?ProductID=1943&category=
[11:23:02] <alex4nder> probably as close to a kit as you'll find for the taig.
[11:27:07] <joe9> alex4nder: that is a good find. thanks. I was checking out their clamping kit and noticed that it was on backorder.
[11:55:00] <Jymmm> This is pretty good... http://www.youtube.com/watch?v=iJ4k7wxYqCo&feature=share
[12:03:58] <IchGuckLive> hi all
[12:05:27] <Jymmm> Is shellac the ONLY alcohol based clear coat?
[12:05:55] <Jymmm> djdelorie: Is shellac the ONLY alcohol based clear coat?
[12:07:44] <IchGuckLive> every guitar stor has shellac in its storige
[12:08:31] <Jymmm> It's expensive though. And I can't find shellac powder locally
[12:11:07] <djdelorie> Jymmm: I don't know
[12:11:20] <djdelorie> I get mine at the paint store, by the gallon
[12:11:32] <Jymmm> djdelorie: shellac?
[12:11:36] <djdelorie> yu
[12:11:39] <djdelorie> yup
[12:12:19] <djdelorie> our local hardware store carries it too
[12:12:19] <Jymmm> djdelorie: I need very little, so I was thinking powder. Especially since prepared shellac has a 3yr shelf life.
[12:12:41] <IchGuckLive> shellac is not delivert as a fluid
[12:12:43] <djdelorie> so buy a quart instead :-)
[12:12:56] <djdelorie> shellac is often delivered as a fluid
[12:12:57] <Jymmm> $15 per qt.
[12:13:04] <Jymmm> Yes, I know.
[12:13:17] <Jymmm> but there is also flake and powde
[12:13:19] <Jymmm> r
[12:13:40] <IchGuckLive> shellac is not stable as fluid under air
[12:14:01] <djdelorie> IchGuckLive: you can just add more alcohol to restore it
[12:14:09] <djdelorie> Jymmm: $8 a gallon
[12:14:11] <Jymmm> djdelorie: do you find your settles alot, meaning you have to mix it well?
[12:14:19] <djdelorie> I haven't mixed mine yet
[12:14:39] <Jymmm> djdelorie: veryexpensive here for some reason. $8/gal would be great.
[12:14:40] <djdelorie> shellac is a solution, not a suspension
[12:15:11] <djdelorie> Zissner $10/qt
[12:15:22] <Jymmm> djdelorie: Ok. Just when I shook the can in the store it didn't feel right =)
[12:15:49] <Jymmm> Yep, but $14/qt instead of $8/gal
[12:15:51] <djdelorie> you can get shellac in spray cans too
[12:15:58] <Jymmm> I need liquid
[12:16:20] <Jymmm> I'd love powder
[12:16:47] <jdh> probably wouldn't be good for your nasal passages.
[12:17:24] <Jymmm> jdh: come on man, go do a line of baking powder!
[12:17:54] <TheLarch> why the need for an ancient biopolymer?
[12:18:17] <Jymmm> I need an alcohol based clear coat
[12:18:38] <jdh> why alcohol
[12:19:02] <Jymmm> fast drying
[12:19:19] <pcw_home> because it easy to remove for repairs? same reason you don't glue violins with epoxy
[12:19:23] <jdh> acetone is fast dring
[12:19:36] <Jymmm> leaves a residue
[12:20:11] <Jymmm> and is toxic compared to alcohol
[12:22:19] <archivist> I just need alcohol :)
[12:22:45] * jdh hands out a few liters of EverClear(tm)
[12:23:06] <jdh> aged over 30 minutes in glass bottles.
[12:23:17] <TheLarch> Jymmm: are you brushing this on?
[12:23:19] <alex4nder> jdh: the burn lets you know it's workig.
[12:23:26] <djdelorie> everclear is the solvent of choice for making food-safe shellac finishes.
[12:23:56] <Jymmm> djdelorie: and 190 proof is ILLEGAL in Calif, 151 proof is legal
[12:24:10] <jdh> .ca.us is so protective.
[12:24:10] <Jymmm> TheLarch: no, dipping.
[12:24:37] <Jymmm> jdh: s/protective/fubared/
[12:24:40] <djdelorie> CA is such a nanny state
[12:24:50] <djdelorie> NH is "Live Free Or Die" :-)
[12:25:17] <Jymmm> We have legal pot! (alot of good that's gonna do me...not)
[12:25:26] <jdh> Connor: where did you get your R8 3-jaw chuck?
[12:25:39] <Connor> Ebay
[12:25:45] <TheLarch> yet CA has a smoking ban in most places yet cannabis is available by prescription
[12:25:55] <jdh> I can't find one.
[12:26:02] <Connor> VERY hard to find
[12:26:17] <alex4nder> TheLarch: you can't smoke weed the same places you can't smoke tobacco
[12:26:18] <jdh> I used to see them all the time when I didn't want one.
[12:26:49] <TheLarch> alex4nder, otherwise it might make sense
[12:27:02] <Jymmm> And get this.... IF you have kids and smoke in the house you can be cited for CHILD ENDANGERMENT
[12:27:55] <TheLarch> and no bans on fast food yet i CA?
[12:28:01] <TheLarch> i/in
[12:28:12] <Jymmm> TheLarch: Oh, there are. By City based.
[12:28:44] <alex4nder> kids should just be able to sue their parents
[12:28:49] <Jymmm> TheLarch: http://blogs.sfweekly.com/thesnitch/2011/11/happy_meal_ban_mcdonalds_outsm.php
[12:29:01] <Jymmm> alex4nder: kramer vs kramer
[12:29:13] <alex4nder> yes
[12:32:36] <TheLarch> Jymmm: UV cured coating are available in 100% solids with zero VOC's, think of the children
[12:34:16] <Jymmm> lol
[12:34:50] <Jymmm> Anyone want to make fireworks? http://www.skylighter.com/mall/chemicals.asp
[12:35:35] <TheLarch> http://www.sciencelab.com/msds.php?msdsId=9923955 ethanol msds
[12:36:17] <Jymmm> jdh: DUDE! Check it out... Pharmaceutical grade!!! http://www.skylighter.com/calcium-carbonate.htm
[12:41:01] <Connor> jdh: Whatcha thinking of doing with the R8 3 Jaw ?
[12:48:16] <jdh> making TTS type holders
[12:49:12] <Connor> Ahh.
[12:49:23] <Connor> Yea. I might try that at some point too.
[12:49:28] <jdh> I can turn the shank down in the lathe, then drill/bore in place on the mill.
[12:49:43] <Connor> How are you going to center it ?
[12:49:47] <jdh> but, turning the shank would be much easier on a cnc'ed platform.
[12:50:16] <jdh> good question. I'm open to suggestions :)
[12:50:26] <Connor> I never came up with one.
[12:51:17] <Connor> Almost as if you need a collet holder on the table.. and you do a similar alignment procedure that you would on a lathe using a bar between centers.. ?
[12:51:18] <Jymmm> Woof? http://www.youtube.com/watch?v=5i4gzIeMOfQ&feature=player_embedded
[12:51:18] <jdh> could center drill in the lathe, then use that as the reference.
[12:52:20] <DJ9DJ> re
[12:55:30] <Jymmm> SAY WHAT?! (Read the description) http://www.skylighter.com/nitrocellulose-lacquer-1-pint.htm
[12:57:24] <jdh> connor: http://www.jtsmach.com/jtswebshop/Workholding/LC134.asp?prodcode=LC134 Yours look like that?
[12:58:31] <Connor> not really, but, that picture is generic.. That might be the 5C shank..
[12:58:51] <Connor> Mine did come with both inside and outisde jaws.
[12:58:55] <jdh> looks like it.
[12:59:24] <jdh> wonder why the 4" is $30 more than the 3"
[12:59:48] <Connor> Huh?
[13:00:00] <Connor> Oh.
[13:00:15] <Connor> I'm noticing that the 3" is more than the 4"
[13:00:31] <Connor> 3" is 125. 4" is 95.
[13:00:46] <jdh> heh... I said it the wrong way.
[13:06:09] <jdh> I can't find any 800watt anymore
[13:10:39] <Jymmm> 800W what?
[13:10:58] <Jymmm> (heh, try saying that fast 3x)
[13:12:44] <Connor> 800watt was ebay seller.
[13:13:01] <Connor> who carried 4" 3aw chucks with R8 shanks.
[13:13:05] <IchGuckLive> 800w spindle ?
[13:13:13] <Connor> No.
[13:13:17] <Connor> that was his alias
[13:13:25] <jdh> http://www.ebay.com/itm/130733406389
[13:13:58] <jdh> guess I woudl need a tiny borign bar too
[13:14:08] <Connor> Why does it say Digital ?
[13:14:32] <Connor> That looks very much like a analog to me. :)
[13:15:47] <Connor> jdh: Or Reamer. I think the holes go all the way through too.. I'll look in just a few
[13:18:30] <IchGuckLive> ok olympia is starting in Europ have a nice weekend
[13:19:34] <archivist> this man needs a cnc http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_07_27_York_Stonemasons/IMG_1280.JPG six weeks work so far
[13:20:12] <archivist> York Mister stonemasons at work
[13:20:17] <archivist> minster
[13:25:38] <jdh> or a mold

[13:27:19] <jdh> I just liked the title/description.
[13:30:02] <Connor> AH.
[15:25:57] <andypugh> This Olympic opening ceremony is quite good. I am vaguely surprised.
[15:26:40] <Tom_itx> i don't think we get to see it until later, i'm not sure
[15:29:41] <cpresser> http://olympia.ard.de/apps/java/london2012/liveplayer/index.html (might now work outside germany)
[15:36:18] <TheLarch> "For legal reasons, access to the desired medium from a location outside of Germany is not possible."
[15:36:28] <TheLarch> time for a VPN
[15:37:41] * cpresser will trade a VPN access. i offer germany and want US :)
[15:39:38] <Jymmm> For future reference US Only http://www.nbcolympics.com/online-listings/live/index.html
[15:43:23] <Jymmm> fucking search engine spam or places that thought they would benefit by offering live streams but dont have the bandwidth
[15:45:16] <Jymmm> This is fucked up http://londonolympic2012tv.com/
[15:45:33] <Jymmm> it's just to sell you some software DVR
[15:46:58] <Jymmm> On NBC will air at 7:30 p.m. Pacific and Eastern time in the U.S.
[15:47:08] <Jymmm> till midnight
[16:14:40] <DJ9DJ> gn8
[16:20:58] <andypugh> Tim Berners-Lee live on stage was a surprise!
[16:22:33] <Jymmm> No, him DEAD on stage would be a surprise!
[16:23:36] <cpresser> or somebody dressed as batman on the stage
[16:23:57] <Jymmm> Joker would be cool though
[17:01:40] <Tom_itx> anybody know a good source for bicycle shifer assembly drawings?

[19:07:46] <WillenCMD> http://www.datasheetcatalog.org/datasheet/toshiba/2211.pdf
[19:08:48] <r00t4rd3d> look at the chip, is one side angled more?
[19:08:50] <andypugh> It has one sloping side
[19:09:21] <r00t4rd3d> newbs i tell ya
[19:09:28] <r00t4rd3d> :)
[19:09:39] <WillenCMD> isn't everyone new at one point in time?
[19:09:43] <WillenCMD> :)
[19:09:46] <r00t4rd3d> you see it now?
[19:10:03] <WillenCMD> no
[19:10:07] <r00t4rd3d> lol
[19:10:10] <andypugh> I haven't seen one marked that way before, though.
[19:10:36] <WillenCMD> it stands straight up, they can write all those numbers on it, but they can't put the number one above one pin
[19:10:39] <WillenCMD> seriously
[19:10:48] <r00t4rd3d> look at the datasheet, top page, the side view
[19:11:04] <andypugh> The edge with pin 1 is chamfered at a different angle.
[19:11:14] <r00t4rd3d> one side of the chip should have a steeper angle
[19:11:31] <r00t4rd3d> steeper angle, left side, pin 1
[19:12:09] <WillenCMD> maybe thats not it, because im telling you both angles are the same
[19:12:24] <WillenCMD> should i go put in on the damn comparator and check the angles
[19:12:24] <r00t4rd3d> you didnt take any bath salts today did you?
[19:12:53] <WillenCMD> just ampetomenes
[19:13:02] <WillenCMD> amphetomens
[19:13:08] <WillenCMD> or however its spelled
[19:13:37] <r00t4rd3d> the dea raided all the head shops around me that sold bath salts and glass cleaner
[19:13:44] <alex4nder> hah
[19:13:50] <r00t4rd3d> couple days ago
[19:13:53] <alex4nder> did they take the 'horny goat weed' as well?
[19:14:05] <r00t4rd3d> synthetics too i think
[19:14:24] <alex4nder> I love fighting losing wars.
[19:14:29] <skorket> I'm considering buying a zen toolworks cnc kit ( here http://www.zentoolworks.com/product_info.php?products_id=74&osCsid=f6un8kg8ml1lqlk781noikptl7 ), with my own nema17 .9 deg stepper motors, an arduino loaded with grbl and 3 a4988 pololu stepper drivers. I primarily want to do PCB routing but it would nice to do some other small stuff too. Does anyone have any experience with the zen toolworks machines? Is it a good choice for
[19:14:29] <skorket> a beginner like me?
[19:14:30] <alex4nder> s/wars/battles/
[19:14:49] <alex4nder> skorket: I've heard you'll have spindle runout problems.
[19:14:54] <alex4nder> but that might be old news.
[19:15:20] <r00t4rd3d> skorket, you have seen cnczone.com?
[19:15:34] <skorket> alex4nder, what is spindle runout?
[19:15:41] <r00t4rd3d> i think there is a zen sub section in the forums
[19:15:42] <andypugh> Why use an Arduino rather than LinuxCNC?
[19:15:52] <alex4nder> skorket: the amount out of round that the bit will spin in the spindle.
[19:15:52] <r00t4rd3d> you can use it with it
[19:16:10] <andypugh> What does the Arduino do?
[19:16:18] <alex4nder> skorket: think of the spindle as a spirograph
[19:16:29] <r00t4rd3d> acts as a controller
[19:16:36] <r00t4rd3d> with a grbl shield
[19:17:21] <andypugh> OK, so where does LinuxCNC fit in
[19:17:27] <r00t4rd3d> more expensive route then a tb6560
[19:17:45] <WillenCMD> http://www.datasheetcatalog.org/datasheet/vishay/83717.pdf
[19:17:52] <WillenCMD> lol helps if you have the right datasheet
[19:17:56] <r00t4rd3d> linuxcnc sends arduino the cordinates i guess, never tried it though just read about it
[19:18:06] <WillenCMD> see the notch, clever clever
[19:18:14] <skorket> oh, whoops, I just saw linux + cnc and assumed this was the appropriate forum. Sorry guys, I don't mean to crash the party
[19:18:22] <andypugh> That's fine.
[19:18:22] <r00t4rd3d> nah man your fine
[19:18:32] <skorket> oh, ok, thanks
[19:18:40] <andypugh> You might find LinuxCNC a more usable solution to the controller puzzle though.
[19:18:45] <r00t4rd3d> cnc in general here pretty much
[19:18:46] <WillenCMD> can we pursuade you to linuxcnc
[19:19:00] <WillenCMD> we offer a gift basket
[19:19:10] <skorket> I'm looking at cnczone, but I don't see anything specifically for zen toolworks. Should I be looking in the forums? The review section seems to be down
[19:19:14] <r00t4rd3d> yeah
[19:19:37] <r00t4rd3d> they have sub sections for every damn thing i think
[19:19:53] <WillenCMD> not machining pornography
[19:20:04] <WillenCMD> won't find that section
[19:20:07] <r00t4rd3d> "sexy girls"
[19:20:12] <r00t4rd3d> dxf files
[19:20:21] <WillenCMD> although, i think a calendar with milling machine's and sexy girls would be a great linuxcnc fund raisor
[19:20:29] <WillenCMD> and lathes
[19:20:37] <andypugh> Shapely Shapers?
[19:20:38] <skorket> alex4nder, meaning the zen cnc is not so accurate?
[19:21:00] <alex4nder> skorket: you have to be careful with words with machinists.
[19:21:17] <r00t4rd3d> a zen would be fine for a beginner
[19:21:17] <alex4nder> skorket: you just won't get the output you expect with a tight tolerance requirement
[19:21:21] <skorket> Yeah, I'm pretty new to this whole thing
[19:21:26] <andypugh> skorket: He didn't get to finish the desciption, but runout refers to how far off the axis of rotation the centre of the toolholder is.
[19:21:45] <skorket> ah, I see
[19:21:58] <alex4nder> r00t4rd3d: it's not that he's a beginner, it's just not got low enough runout for any type of SMT PCB
[19:22:06] <alex4nder> with the spindle they offer
[19:22:07] <r00t4rd3d> you are better off building a cnc machine though
[19:22:20] <alex4nder> if you don't need to make a board for SMDs, it'll work
[19:22:20] <WillenCMD> don't you kind of need a machine to build one?
[19:22:30] <andypugh> For $350 You probably can't go far wrong, to be honest.
[19:22:38] <WillenCMD> thas what i was thinking
[19:22:44] <WillenCMD> looks like great practice
[19:22:45] <alex4nder> just set your expectations appropriately
[19:22:59] <r00t4rd3d> the machine is the easy part, the software is the bitch
[19:23:02] <alex4nder> you're not going to be doing inconel turbine blades with it
[19:23:30] <skorket> It would be nice to do SMD but maybe that's too ambitious. I'd be happy with something that at least gets close.
[19:23:35] <WillenCMD> root: thats what linuxcnc and this IRC is for :)
[19:24:00] <alex4nder> skorket: the problem with CNC is everything you don't know about.
[19:24:11] <skorket> I'm running into the problem of not having much experience with the mechanical side of things. I can see myself easily spending much more than $350 (or $450 after everything) and getting a machine that isn't nearly as accurate
[19:24:40] <alex4nder> skorket: I've spent $3k on my machine, and it isn't done yet
[19:24:40] <WillenCMD> for that price, you won't find anthing accurate
[19:24:48] <alex4nder> I'm still working on things.
[19:24:48] <skorket> I figure I'd start with a kit and go from there. The zen toolworks one seems like it was a good beginner cnc
[19:24:56] <WillenCMD> just an accurate spindle can run 1k to 2k used
[19:25:03] <r00t4rd3d> you could probably use the machine to improve itself though
[19:25:16] <WillenCMD> what about sherline?
[19:25:20] <r00t4rd3d> lol
[19:25:28] <r00t4rd3d> $$$$$$$$$$$$$$$$$$$$$$$$$$$$$
[19:25:28] <andypugh> Yeah, I think it looks great for a toe-dipping excercise. And you might then decide that what you really wanted was a lathe, or a router, or a reprap.
[19:25:28] <alex4nder> WillenCMD: you might as well go Taig at that point
[19:25:45] <alex4nder> but a used Taig is a good machine
[19:25:51] <WillenCMD> ill second that
[19:25:55] <WillenCMD> for what they are worth
[19:26:32] <WillenCMD> i can't believe they can sell that for $350
[19:26:32] <skorket> I was thinking of just purchasing one of their spindles: http://www.zentoolworks.com/product_info.php?products_id=135
[19:26:32] <andypugh> Then you might as well have a Boxford. But they are a bit limited compared to a full size VMC, but thet can't make boat hulls so......
[19:26:47] <WillenCMD> lol
[19:26:49] <WillenCMD> where do you draw the line?
[19:26:56] <alex4nder> yah
[19:26:57] <alex4nder> it's a slippery slope
[19:27:13] <andypugh> The machine looks fine. That spindle looks very poor.
[19:27:14] <r00t4rd3d> http://www.shapeoko.com/
[19:27:27] <WillenCMD> i see it as stepping stones, buy a small decent machine, use it to make a medium machine and so on
[19:27:40] <r00t4rd3d> 199 for just the mechanics
[19:27:43] <skorket> any suggestions on a sub $100 (good) spindle?
[19:28:01] <WillenCMD> what size tooling are you going to use?
[19:28:09] <andypugh> As far as I can see that "spindle" has no tool spindle bearings, and most motors that style have plain bushes for bearings.
[19:28:19] <r00t4rd3d> http://zentoolworks.com/product_info.php?cPath=16&products_id=122
[19:28:40] <r00t4rd3d> i doubt thats "good" but more like "works"
[19:28:41] <WillenCMD> that spindle looks like junk,
[19:28:56] <WillenCMD> ill give you a sherline spindle
[19:29:00] <WillenCMD> youll need the motor mount
[19:29:03] <r00t4rd3d> ok give me one
[19:29:03] <WillenCMD> and pay shipping
[19:29:06] <WillenCMD> really?
[19:29:12] <WillenCMD> i have one laying around
[19:29:15] <r00t4rd3d> where you live?
[19:29:20] <WillenCMD> Missouri
[19:29:34] <r00t4rd3d> medium flat rate box
[19:29:49] <WillenCMD> you got it, ill send the the drill chuck and collets
[19:30:01] <r00t4rd3d> you got paypal?
[19:30:09] <WillenCMD> whats paypal ;)
[19:30:17] <WillenCMD> yes i do
[19:30:29] <WillenCMD> there is a minor catch
[19:30:35] <alex4nder> there always is
[19:30:42] <andypugh> skorket: How much is a Dremel round your way? They can be an OK spindle, and also be used as a conventional hand tool.
[19:30:43] <WillenCMD> i drill 4 5/16 x 18 holes in the back
[19:30:49] <WillenCMD> drilled*
[19:30:58] <WillenCMD> but it still works gerat
[19:30:59] <WillenCMD> great
[19:31:07] <r00t4rd3d> got a pic of it?
[19:31:13] <skorket> I have a dremel...I thought it better to go through the zen site, but maybe not. It's also a question of attaching it to the z-axis...
[19:31:21] <WillenCMD> its at work, i have a solidworks rendering lol
[19:31:40] <r00t4rd3d> how big is it?
[19:32:02] <r00t4rd3d> what does it require for power
[19:32:17] <WillenCMD> its about 4"H x 3"w, i have a nema 23 motor mount kit that came with it
[19:32:37] <WillenCMD> its extra from a small drilling machine i designed for a local shop
[19:32:41] <andypugh> skorket: This spindle relieves the motor bearings of taking tool loads, and has proper spindle bearings. And is cheaper: http://www.cnconabudget.com
[19:32:50] <WillenCMD> so i didn't pay for it
[19:33:06] <r00t4rd3d> i could do small flat rate box then :)
[19:33:18] <WillenCMD> i even have endmill holders up o 3/8
[19:33:37] <WillenCMD> 3/16, 1/4, 3/8 threaded endmill holders
[19:33:48] <WillenCMD> you can see it on sherline's website
[19:36:07] <skorket> andypugh, do you have a pointer on where to get adapters to fit it to the z-axis?
[19:36:24] <andypugh> It seems to come with a bracket.
[19:37:59] <andypugh> I think you would drill through the flat plate on the Z axis and bolt through from the back.
[19:44:04] <skorket> OK, well, thanks for the advise guys.
[19:52:40] <WillenCMD> how do i know what the led current rating is for the opto?
[19:52:43] <WillenCMD> its not on the datasheet
[19:52:54] <WillenCMD> http://www.datasheetcatalog.org/datasheet/vishay/83717.pdf
[19:52:58] <WillenCMD> is it standard?
[19:59:32] <jdh> not the 60mA?
[20:00:02] <WillenCMD> i was told to use a resistor with them
[20:00:12] <WillenCMD> from the microcontroller
[20:00:53] <jdh> oh, all the parts are in there. Which one are you using?
[20:02:44] <WillenCMD> 4n38
[20:02:53] <WillenCMD> vishay
[20:03:28] <jdh> 390 for 10mA assuming you are driving it with a 5v uC
[20:05:28] <WillenCMD> yes i am
[20:06:14] <andypugh> Max rating is 60mA, bit that seems very high. I have always assumed 10mA.
[20:07:01] <jdh> the 4n25/26/etc. say 50mA
[20:07:03] <andypugh> The CTR is rated at 10mA
[20:54:00] <Tom_L> some of these could be handy for some of you: http://www2.electronicproducts.com/Engineering_Calculators_and_Tools.aspx
[21:03:00] <dew_addict> Anyone here uses FreeCAD software?
[21:08:37] <tjb1> No, but draftsight works great :)
[21:08:50] <WillenCMD> i wouldn't listen to a thing tjbl says
[21:09:03] <tjb1> >:(
[21:09:03] <WillenCMD> notorious for blowing smoke out of his ass
[21:09:11] <WillenCMD> thats what i have heard
[21:09:16] <WillenCMD> :)
[21:09:33] <tjb1> Get that solidworks drawing done yet? :)
[21:09:37] <WillenCMD> i was just looking into free cad/cam software yesterday
[21:09:41] <Jymmm> i wouldn't listen to a thing WillenCMD say, notorious for blowing smoke out of his ass
[21:09:55] <tjb1> Jymmm sucks smoke up his :)
[21:09:58] <dew_addict> heh
[21:10:10] <WillenCMD> atleaste im notorious, thats something to be proud of
[21:10:22] <tjb1> Hey WillenCMD, finish the drawing!
[21:10:34] <dew_addict> as far as I know, draftsight doesn't do 3d solid right?
[21:10:36] <WillenCMD> yes i did you wanted an 8 axis robotic arm right?
[21:10:49] <tjb1> 15 axis
[21:11:11] <dew_addict> 256 axis is better. :)
[21:11:36] <tjb1> ∞ axis is best
[21:11:56] <WillenCMD> how many axis are humans?
[21:12:00] <tjb1> enuff.
[21:12:15] <dew_addict> 2, walks like a penguin
[21:12:28] <tjb1> Serious Willen, you get it done? :(
[21:12:46] <WillenCMD> no but i did start on it
[21:12:53] <WillenCMD> and my wife works all weeknd
[21:12:57] <WillenCMD> weekend
[21:13:01] <tjb1> You said that last weekend lol
[21:13:01] <WillenCMD> so ride my ass when im on here
[21:13:12] <WillenCMD> i lied last weekend
[21:13:16] <WillenCMD> just kidding
[21:13:17] <Jymmm> GET A ROOM you two!
[21:13:35] <WillenCMD> i thought this was a room
[21:13:51] <Tom_itx> not the type you're looking for
[21:13:53] <Jymmm> This aint #ridemyass, m'kay
[21:13:55] <alex4nder> WillenCMD: this is a channel
[21:13:56] <WillenCMD> that does sound pretty bad
[21:14:09] <tjb1> Look at everyone ride his ass :D
[21:14:22] <alex4nder> WillenCMD: yah, better words are needed.
[21:15:06] <WillenCMD> oh well, whats done is done... i often say before i think
[21:15:11] <tjb1> Willen, you said you could do that in 3 hours
[21:15:17] <WillenCMD> i can
[21:15:30] <WillenCMD> i work two jobs man...
[21:15:42] <tjb1> excuses
[21:15:45] <WillenCMD> my leg hurts
[21:15:48] <WillenCMD> i have a cough
[21:15:53] <tjb1> Hey Jymmm, there are actually people in that room.
[21:16:05] <Jymmm> tjb1TMI

[21:16:46] <tjb1> But sadly no, Jymmm did not join to see
[21:17:55] <Jymmm> and never will
[21:17:59] <dew_addict> tjbone
[21:18:08] <dew_addict> got it
[21:18:40] <tjb1> Hey Jymmm, its about time for me to have legitimate questions relevant to this channel
[21:19:13] <tjb1> Wont that be swell?

[21:39:11] <ReadError> thats pretty much complete ;)
[21:39:15] <ReadError> minus props
[21:39:34] <tjb1> I wanted to see the props :)
[21:40:03] <tjb1> It would be cool if you could sync the motors and have the props weave each other
[21:41:13] <tjb1> Build that one next ;)
[21:42:01] <ReadError> well

[22:50:38] <jdh> anyone know the differnece between o1 drill rod and w1 drill rod?
[22:51:06] <cradek> you're supposed to harden O in oil and W in water
[22:52:09] <jdh> does one cut easier? Any difference if you aren't going to harden it anyway?
[22:52:25] <cradek> I don't know that, sorry
[22:52:36] <jdh> is oil vs. water a chemical thing or just how fast it quenches or what?
[22:53:09] <cradek> I've already shared everything I know about it :-)
