[03:17:38] <Loetmichel> mornin'
[03:21:45] <mazafaka> morning
[09:23:29] <JT-Shop> http://www.youtube.com/watch?v=ZhICrb0Tbn4&feature=player_embedded#!
[09:29:41] <archivist> you can hear the hob is not concentric
[09:40:02] * Loetmichel is painting... slowly there is a mini spindle emerging... just a few more lines and then i can build it, the materials are here... ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=12757
[09:40:53] <archivist> you mean drawing not painting probably
[09:44:06] <Loetmichel> its more like painting 'cause i do it with corelDraw ;-)
[09:48:06] <Loetmichel> i hope the Motor will be powerful enough, its only 240W @ 12V... 20kRPM.
[09:48:29] <Loetmichel> but as the Mill for it is made from PVC i see no problem ;-)
[11:39:21] <pfred1> just reading the URL in the topic didn't NIST name EMC EMC?
[11:45:37] * pfred1 wonders if EMC will try to go after these guys http://www.isd.mel.nist.gov/projects/rcslib/emc_links.html
[11:46:14] <pfred1> who have enough nuclear weapons to vaporize the surface of the planet at least 7 times over
[12:35:05] <mrsun> hmm, a bit crammed for space, was thinking to make a mill that stands up against the wall =)
[12:35:07] <mrsun> for flat stuff
[12:35:34] <mrsun> insted of taking like 200x100cm of space it would take like 100x40cm :P
[12:42:22] <syyl_> like the saws used for sheet-work?
[12:42:27] <pfred1> what is that in english?
[12:42:55] <syyl_> http://images.worldsoft-cms.info/wcms/ftp/p/pfisterkuechen.ch/siteimages/2252.jpg
[12:42:59] <syyl_> that as a milling machine?
[12:43:20] <pfred1> that is a break down saw
[12:44:07] <syyl_> there are also milling machines that stand up vertical...
[12:44:15] <syyl_> most for sheetmetal work
[12:44:22] <pfred1> yeah real pain to clamp stuff too
[12:44:38] <syyl_> slightly angled and vac..
[12:45:11] <pfred1> syyl_ you ever machine much ferrous metals?
[12:45:23] <syyl_> most
[12:45:41] <pfred1> then you should know you have to hold that stuff pretty solid
[12:46:21] <syyl_> i usualy place it on the table of the machine and fix it with a strip of ducttape
[12:46:25] <syyl_> issn that the right way?
[12:46:37] <pfred1> if it works for you then it is
[12:46:50] <archivist> the direction it is held is a separate problem to horizontal/vertical
[12:47:08] <syyl_> serious: i know my trade, no need to teach me :P
[12:49:37] <syyl_> ah
[12:49:38] <syyl_> http://www.steinhauer.de/en/mechanical-engineering/cnc-machining-center/ecab-workcenter
[12:49:43] <syyl_> thats the machine i was refering to
[12:49:46] <pfred1> I imagine these sheet metal mills either use very small diameter bits or tooling that does not physically touch the work such as sinkers or lasers or something
[12:50:46] <syyl_> (that one uses pneumatic fixtures for clamping)
[12:51:07] <pfred1> air cylinders?
[12:51:14] <syyl_> almost
[12:51:18] <syyl_> air muscles
[12:51:23] <pfred1> not quite vacuum then
[12:51:27] <syyl_> no
[12:51:35] <syyl_> but you can also add a vac plate to it
[12:51:53] <syyl_> depends on what you want to do :)
[12:52:20] <pfred1> I can see vacuum working for some operations
[12:53:13] <syyl_> of course its not suitable for every kind of work
[13:03:57] <archivist> and for fun, reduce the cut depth to match work holding and work stiffness sometimes
[13:04:42] <syyl_> force the machinist to think about his work? ;)
[13:05:10] <archivist> this was a bugger http://gears.archivist.info/gears/p1010084_500.jpg
[13:06:11] <syyl_> thats a nice setup
[13:06:31] <syyl_> ratchet wheel for a clock?
[13:07:01] <archivist> yes an escape wheel, hod to mount it and clean up the spacing
[13:07:06] <archivist> had to
[13:08:14] <syyl_> had such a "free float" setup last week, too
[13:08:16] <syyl_> http://dl.dropbox.com/u/24396704/2012-01-28_14-32-36_967.jpg
[13:08:20] <archivist> but needed to be done after mounting on its spindle so the lightest of cuts
[13:08:36] <syyl_> workpiece supported by a prism chucked to the table
[13:08:40] <archivist> I saw your pics :)
[13:08:59] <syyl_> :)
[13:09:06] <syyl_> did you rework a finished wheel?
[13:09:17] <archivist> yes
[13:10:02] <syyl_> seems like one of those jobs at wich some people say "that cant be done.."
[13:10:10] <archivist> I was fixing a badly made "kit" for someone
[13:10:39] <archivist> the shaft for that wheel was more fun
[13:11:33] <syyl_> long and thinn? ;)
[13:11:37] <archivist> http://gears.archivist.info/gears/p1010058_500.jpg original above
[13:12:04] <syyl_> did you mill the worm?
[13:12:53] <archivist> yes, just trying to fins a pic, the clack before any work http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_03_06_Merlin_band_clock/
[13:13:31] <syyl_> mh nice looking
[13:13:35] <syyl_> a bit steam-punkish
[13:13:59] <archivist> it drives the worm the wrong way
[13:14:23] <syyl_> ah, the long vertical shaft?
[13:14:36] <archivist> yes
[13:15:49] <archivist> found it http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_10_07/2008_10_07_Merlin_worm/p1010053.jpg
[13:16:04] <cradek> the crown wheel with seconds directly on it is awesome
[13:17:13] <cradek> (although it's very hard to tell what time it is)
[13:17:35] <syyl_> ok, that setup is realy special :D
[13:17:36] <pfred1> cradek that is relative
[13:18:06] <cradek> is it 8 day?
[13:18:20] <archivist> yes
[13:20:52] <archivist> syyl_, the sacrificial continuous support took some thinking after earlier attempts were failing due to shaft flex
[13:21:10] <syyl_> :D
[13:21:14] <syyl_> it looks strange
[13:21:21] <syyl_> but it seems to have worked fine
[13:21:43] <Jymmm> It looks GOT ER DONE =)
[13:22:01] <Jymmm> archivist: How many attempts before that?
[13:22:10] <archivist> it also demonstrates strange setups where CAM wont go :)
[13:22:27] <syyl_> hrhr
[13:22:56] <archivist> Jymmm, iirc that is the third attempt which worked
[13:23:44] <Jymmm> archivist: Oh, not bad at all. Was it a bitch to get it at (what looks like) 45deg and aligned in all axis?
[13:24:10] <Jymmm> (plural)
[13:24:19] <archivist> would have been easier if I had built the 5th axis by then
[13:24:27] <Jymmm> heh
[13:24:36] <archivist> it convinced me of the need
[13:54:45] <Jymmm> $1000 for a push mower?! http://sfbay.craigslist.org/sby/grd/2825866304.html
[13:56:53] <syyl_> must be the best mower in the world ;)
[13:57:08] <syyl_> its hydrostatic self-propelled
[13:58:00] <pfred1> that is what my lawn tractor cost
[13:58:09] <pfred1> least i get to sit down on it
[13:58:14] <syyl_> same here...
[13:58:25] <pfred1> it is hydro too
[13:58:35] <syyl_> ours not
[13:59:03] <pfred1> I've used the fork kind not too keen on them
[14:00:23] <pfred1> I have a Honda self propelled too but right now the rope spring is busted on it
[14:00:54] <WalterN> http://www.grasshoppermower.com/ <3
[14:00:59] <pfred1> would be nice to get it back into service
[14:23:53] <Jymmm> I'm thinking about selling my router. Besides travel, what else should I put in the ad as far as "specs" go? Accuracy? Repeatability? Tolerances? Something Else? I'm not sure what ppl see/ask that's just bullshit (snake oil) and what is real.
[14:32:14] <pfred1> Jymmm brand and model?
[14:56:02] <ENG> Hello is this channel active? I have a question regarding configuring the parrallel port for my linuxcnc machine, can anyone help me?
[14:57:48] <ENG> I've tried changing the parallel port pins in the .hal file to configure my machine, however this causes the LinuxCNC program to crash. Is there another way that I am to set the parallel port pins?
[14:57:57] <jdhNC> ask a specific question and see!
[14:58:36] <jdhNC> did you start out with the stepconf wizard?
[14:59:42] <ENG> no, I can not find the stepconf wizard? I have been reading through the integrator manual and I can really pinpoint how it is I change the parallel port pins for the step and direction of each axis
[15:00:56] <ENG> oh wow that was easy to find the stepconf wizard. I'll try learning about the stepconf wizard for a bit. Thank you.
[15:01:41] <pfred1> I just went with the defaults for parallel port pins
[15:02:06] <jdhNC> woohoo... I had a useful answer!
[15:02:28] <pfred1> but I imagine if I was to change them I'd start out in stepconf
[15:02:37] <Jymmm> jdhNC: Fine, once in a lifetime. You can take the dunce cap off (for the moment).
[15:02:53] <pfred1> Jymmm what kind of router are you selling?
[15:03:06] <Jymmm> Gantry
[15:03:08] <jdhNC> I used stepconf many times until I had to add something, now I can't use it and am forced to read every time.
[15:03:35] <pfred1> jdhNC you can backup your ini file then diff it
[15:04:21] <pfred1> jdhNC everytime i run stepconf it insists on putting axis in as my interface so I have to go in and edit that
[15:04:47] <pfred1> I figure if it gets to be too much I'll write a sed script to change things back
[15:05:02] <Jymmm> Use the wizrd for initial setup, then manually edit after that.
[15:05:09] <jdhNC> what do you use?
[15:05:15] <pfred1> tkemc
[15:05:28] <jdhNC> what does it do better/differently?
[15:05:34] <pfred1> it doesn't crash my X session
[15:05:52] <Jymmm> Neither does KeyStick =)
[15:05:59] <pfred1> plus i can get a lot higher step rate running it han Axis
[15:06:08] <jdhNC> I guess that could be an advantage, but axis doesn't crash mine.
[15:06:28] <pfred1> something is buggy with my GL libs
[15:06:38] <jdhNC> non-ubuntu?
[15:06:47] <pfred1> anytime I run any GL app and I have the RTAI extention going X crashes
[15:06:52] <pfred1> yes
[15:07:19] <jdhNC> oh, you are one of them.
[15:07:20] <pfred1> I might be able to change to the software GL accel but I'm taking a big enough performance beating as it is
[15:07:36] <pfred1> so I never even bothered trying to do that
[15:08:13] <pfred1> i just compiled RTAI and EMC and put it on a Debian system
[15:08:21] <pfred1> I don't need Ubuntu
[15:08:39] <pfred1> in X I'm running 40 total processes
[15:08:55] <pfred1> as opposed to 160
[15:09:48] <pfred1> jdhNC last week the RAM died in that machine and I ran X with a total of 22MB of RAM
[15:10:07] <pfred1> I thought it was acting a little sluggish
[15:10:32] <jdhNC> c'mon, I used to run X on a 386 with 8mb
[15:10:43] <pfred1> which version?
[15:10:57] <pfred1> xfree86?
[15:10:59] <jdhNC> dunno, it was 1993 or so.
[15:11:44] * Jymmm slaps jdhNC with a 21st-Century-Clue-By-Four
[15:11:55] <pfred1> that box will sit in X with 32 MB total RAM used
[15:12:17] <pfred1> good luck doing that on Ubuntu
[15:12:41] <pfred1> if you can manage it you're better at Linux than I am
[15:14:17] <pfred1> plus it boots up in 16 seconds which isn't bad for a 1 Ghz P3 http://img87.imageshack.us/img87/2250/wedoct27bootchart.png
[15:14:54] <pfred1> stock it took 22 seconds
[15:15:01] <Jymmm> Heh, I'm selling a P3 1G laptop
[15:15:13] <pfred1> craptops are not towers
[15:15:28] <Jymmm> and it has 512MB ram even =)
[15:15:35] <pfred1> tower o powah
[15:16:00] <pfred1> due to the chipset in that box 512MB is its max
[15:16:30] <Jymmm> Ok, Dual AMD Opteron 200 CPU's with 8 DIMM slots, 4 per cpu. 8 SATA ports, dual gig nics.
[15:16:48] <pfred1> I'd like to ty EMC on an AMD
[15:17:04] <Jymmm> no onboard video, so you can use your own video card.
[15:17:20] <pfred1> I'm low on vid adapters at the moment
[15:17:37] <pfred1> I just have some junky ati laying around
[15:17:38] <jdhNC> I have 8 or 10 TVGA8900's you can have
[15:17:57] <pfred1> it was worse than my on board when it even worked
[15:18:00] <Jymmm> I'm going to be including that mobo/cpu with the router, along with a few other choice items
[15:19:04] <pfred1> next system I buy will be one of those mini atoms
[15:20:25] <pfred1> Jymmm what kind of latency did you get with your AMD?
[15:20:31] <Jymmm> I have one of these http://i54.tinypic.com/2i09ndk.jpg
[15:20:54] <Jymmm> Including the rolling case to transport/store it in.
[15:21:36] <Jymmm> pfred1: Dont know yet, it's a server mobo and haven't tested it yet. Still sitting on my bench.
[15:21:42] <pfred1> oh
[15:21:55] <pfred1> yeah it does sound pretty beefy
[15:22:03] <Jymmm> It's a SuperMicro mobo
[15:22:06] * pfred1 is going in the other direction less is more
[15:22:31] <Jymmm> I think this is it... http://www.supermicro.com/Aplus/motherboard/Opteron/nForce/H8DCE.cfm
[15:22:55] <Jymmm> I have a coupel mobos around here
[15:23:14] <pfred1> me too but all junk
[15:23:47] <Jymmm> pfred1: I'll sell ya some, but the shipping might be rough.
[15:25:41] <pfred1> I want to get something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16856119037
[15:27:39] <pfred1> its cute
[15:45:09] <syyl_> http://dl.dropbox.com/u/24396704/wzw_spindel9.jpg
[15:46:10] <syyl_> getting close with my toolchanging spindle ;)
[15:47:52] <archivist> you could get less overhang bearing to opening
[15:49:57] <pfred1> foxconn needs to beat their webmasters harder half the links on their site don't work
[15:49:57] <syyl_> a bit, yes
[15:50:10] <syyl_> but i need room for the spindle not on front..
[15:50:58] <archivist> what collet type is that
[15:54:10] <syyl_> hmm
[15:54:12] <syyl_> own design
[15:54:23] <syyl_> borrowed from a commercial highspeed spindle
[15:54:34] <syyl_> for tools with 6mm shank
[15:54:41] <mrsun> hmm
[15:54:55] <mrsun> how does that fit? "own design borrowed from commercial highspeed spindle" .. do you see the error int hat? :P
[15:54:55] <pfred1> what is 6mm a quarter of an inch?
[15:55:06] <mrsun> 1/4 about yes
[15:55:11] <mrsun> 6.35 i think is a quarter
[15:55:29] <pfred1> mrsun ah i see a cheap 1/4"
[15:55:39] <mrsun> no a real 6MM =)
[15:55:54] <mrsun> imperial units are just make beleive
[15:56:04] <pfred1> mrsun just like all the 13mm is really a half an inch
[15:56:19] <pfred1> mrsun until you get there is is still a quarter of a million miles to the Moon
[15:56:34] <syyl_> fsk
[15:56:43] <syyl_> not another imperial /metric discussion
[15:56:50] <mrsun> haha :P
[15:57:00] <syyl_> metric is better, fullstop
[15:57:31] <syyl_> and yes, i see the error, mrsun ;)
[15:58:06] <archivist> I would change one of the registers on the body so I could turn the body outer all in one session
[15:58:36] <archivist> and part off from that register
[16:01:04] <pfred1> mrsun where is the error?
[16:01:18] <mrsun> in what he wrote? :)
[16:01:24] <syyl_> that makes sense, archivist
[16:01:26] <mrsun> if he borrowed it from a design it cant be his design :P
[16:01:29] <syyl_> *takes a note"
[16:02:14] <Loetmichel> *waaah* years later....
[16:02:23] <pfred1> mrsun why not? he is incorporating it into a new design of his what you're saying is because it has been done before no one can use straight lines
[16:02:49] <archivist> syyl_, thinking which parts and what order to machine can keep one quiet for a bit
[16:02:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12763 <- three hours ago...
[16:03:04] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12766 <- now
[16:05:37] <pfred1> Loetmichel takes a long time to work beryllium doesn't it?
[16:06:49] <mrsun> you just try unobtanium
[16:08:13] <pfred1> Loetmichel you're going to have the coolest CPU heatsink of all time though
[16:08:55] <Jymmm> Loetmichel: it took you three hours to blow away the dust?
[16:09:25] <pfred1> Jymmm you don't want to get Berylliosis
[16:09:46] <Jymmm> Loetmichel: And I notice the Ikea Light too =)
[16:10:16] <Loetmichel> pfred1: its just a hard aluminium... (7075?)
[16:10:32] <Loetmichel> pfred1: isnt a heatsink.
[16:10:39] <pfred1> when aliens finaly visit Earth their first stop will undoubtedly be Ikea
[16:11:01] <Jymmm> Since when does Area 51 have an Ikea?
[16:11:07] <Loetmichel> will be a mini Mill spindle for a "open workshop" around here.
[16:11:22] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12757
[16:11:45] <pfred1> Loetmichel make me a beryllium heatsink
[16:12:38] <pfred1> so are you making the piece on the bottom?
[16:12:49] <Loetmichel> yes
[16:13:27] <pfred1> the bottom being by the 43.00 mm dimension?
[16:14:32] <Loetmichel> yes
[16:14:43] * pfred1 guessed good
[16:15:10] <pfred1> Loetmichel have you given any thought to making a lathe for yourself?
[16:15:55] <Loetmichel> pfred1: i have a lathe. two to be precise
[16:16:11] <pfred1> Loetmichel why didn't you make this piece on it?
[16:16:20] <Loetmichel> but they are not CNC so i am to lazy to use them
[16:17:09] <Loetmichel> and because there are some square parts and i dont want to clamp it two times to get the bearing seat precise
[16:17:50] <Loetmichel> i will use a t-slot-bit fpr the other bearing seat
[16:18:36] <syyl_> how are you going to measure behind the relief?
[16:18:39] <Loetmichel> Jymmm: the ikea light is great. compact and not in the way
[16:18:48] <Loetmichel> syyl_: i do not ;-)
[16:19:00] <Jymmm> Loetmichel: Yeah, after you told me I got one.
[16:19:23] <pfred1> I have some high intensity lamp I picked up at a garage sale on my mill
[16:19:32] <Loetmichel> and brighter than my camera ca cope with ;-)
[16:19:47] <Jymmm> pfred1: the ikea one is LED on a gooseneck.
[16:20:04] <pfred1> Jymmm the garage sale lamp was a quarter
[16:20:19] <Loetmichel> pfred1: and its 3W and only 10 eur over here ;-)
[16:20:20] <syyl_> and where kann Jymmm your garage sale lamp?
[16:20:35] <Jymmm> pfred1: and $5 on the electric bill =)
[16:20:36] <pfred1> Loetmichel a quarter is about a tenth of a euro
[16:20:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12223
[16:21:15] <Loetmichel> pfred1: yeah, but no garage sales around here. and the ikea lamp is NEW 10 bucks ;-)
[16:21:38] <pfred1> Loetmichel the photons my lamp emits are all guaranteed new
[16:21:43] <Loetmichel> and the gooseneck is a fine feature
[16:21:54] <Loetmichel> pfred1: troll
[16:23:10] <pfred1> when the bulb blows out in my lamp I'll probably jamb a harbor freight flashlight into it
[16:23:20] <pfred1> they'e 9 LEDs
[16:23:32] <pfred1> and free
[16:24:44] <Loetmichel> gn8, i better go to sleep than waste my time with a troll
[16:26:00] <pfred1> yeah go to sleep babies get cranky when they're tired
[16:26:18] <syyl_> you realy seem to have a problem...
[16:26:23] <Loetmichel> pfred1: why should i? I have a wife which will do that for me ;-)
[16:26:36] <Loetmichel> so, bedtime now ;-)
[16:26:53] <pfred1> Loetmichel a wife that will put you to sleep?
[16:26:55] <Loetmichel> (he told me in query to go and F*** myself)
[16:27:30] <pfred1> what?
[18:24:58] <skunkworks> fenn: !!
[18:31:35] <fenn> hi. heard about the name change
[18:32:03] <skunkworks> what name change? ;)
[18:32:46] <skunkworks> still on the west coast?
