[00:16:31] <jesseg> Howdy Folks.
[00:16:35] <jesseg> So here's a weird one for ya
[00:17:19] <jesseg> Our LinuxCNC live disk CD (whereof which we had set up LinuxCNC as 4 axis inch mode)
[00:17:44] <jesseg> Anyway, Slic3r of course puts stuff out in mm
[00:18:11] <jesseg> and LinuxCNC was essentially working, EXCEPT it was moving a whole inch for each mm requested on the A axis...
[00:32:50] <CaptHindsight> http://www.linuxcnc.org/docs/devel/html/config/ini_config.html#_the_ini_file_components
[00:32:59] <CaptHindsight> look up units
[00:33:26] <CaptHindsight> http://www.linuxcnc.org/docs/2.4/html/config_ini_config.html
[00:37:47] <jesseg> Thanks Cap'n
[00:39:34] <jesseg> We have LINEAR_UNITS = inch
[00:39:46] <jesseg> and
[00:39:47] <jesseg> http://www.linuxcnc.org/docs/devel/html/config/ini_config.html#_the_ini_file_components
[00:39:50] <jesseg> oops wrong paste
[00:39:53] <jesseg> [AXIS_3]
[00:39:54] <jesseg> TYPE = LINEAR
[00:43:24] <jesseg> X, Y, and Z are all handled correctly.
[00:44:03] <jesseg> But I suppose Slic3r could be changing the unit type for just the A axis
[00:58:04] <jesseg> or maybe slicer set setting the unit for XYZ but NOT for A, so A is being left at the default of inches
[00:58:18] <jesseg> our plan is to try setting up LinuxCNC in mm mode and see if that works better
[02:11:15] <Deejay> moin
[02:25:07] <RyanS> http://www.youtube.com/watch?v=BoFSz2LGgkM&feature=youtu.be seems like a good method, although I would have to have belt drive at the headstock end
[03:41:04] <dchevak> Hi there
[03:42:09] <dchevak> well I have a 14x40 wilton lathe and like to convert it to cnc
[03:43:40] <dchevak> I have been googling manual to cnc conversion but most are on smaller lathes would like some help with stepper motor size and ball screw type and size ?
[03:45:01] <archivist_herron> you may be better off thinking about servo drives on a larger lathe
[03:45:25] <dchevak> if anyone know of a site that shows how to would be great I seen a post before on a 14x40 lathe where he added the stepper motors but was also able to use it manualy for 1 offs that is more on the line of what I want
[03:46:55] <archivist_herron> some add hand driven encoders for hand use
[03:48:57] <archivist_herron> some examples http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Case_Studies
[04:02:35] <RyanS> I really don't get carbide tools on hobby lathes, HSS produces a better result
[04:03:00] <lv-esad> hi there
[04:03:38] <archivist_herron> RyanS, depends, one has to use carbide correctly
[04:06:36] <RyanS> hmm but requires more spindle power because it can't hold as sharp edge as HSS ... Something to do with the structure of carbide
[04:45:50] <mrsun_> carbide endmills atleast feels sharp as hell =)
[04:45:57] <mrsun_> insert tooling tho has quite dull edges =)
[04:46:09] <mrsun_> ahh you are talking about lathes =)
[04:46:30] <mrsun_> RyanS, but there are insert tooling that is quite sharp also =) the ones made for alu etc for example =)
[04:46:47] <archivist_herron> you can get ground edge carbide inserts for finish turning on lathes
[04:50:10] <RyanS> I don't know I kind of like the idea of grinding any shape you want by having spare HSS bits
[04:55:26] <Loetmichel> harhar: storm "xaver" flodding the city: definetly no fucks given: https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-ash3/1452124_10152491759674988_80074810_n.jpg
[05:06:02] <TekniQue> hah
[06:51:49] * jthornton wonders why the propane tank runs empty after the snow storm
[06:53:54] <Tom_itx> bit chilly?
[06:54:16] <Tom_itx> 16░ F here
[06:54:46] <jthornton> its 25 F here and 58 F in the house
[06:55:02] <Tom_itx> time to fire up the log splitter
[06:55:10] <jthornton> just waiting for the propane line to clear from the big tank
[06:55:23] <Tom_itx> froze?
[06:55:28] <jthornton> I just had to switch tanks
[06:55:32] <Tom_itx> ahh
[06:56:05] <jthornton> have to cycle the heater a few times to purge the line of air
[07:00:06] <jthornton> Houston we have ignition
[07:00:19] <Tom_itx> no wood burners in either place?
[07:00:32] <jthornton> I normally don't let the tanks run empty but I want to change the gauge on the 300 gallon tank
[07:00:53] <jthornton> no wood burners in the house
[07:04:14] <ries> Gents, out of curiocity, if you would mill a ring (the one you put on your finger) with some text and all. What sort of resolution should one think of (in MM) like 1/100 mm or 1/1000 ?
[07:05:58] <jthornton> are you engraving a paragraph on the ring?
[07:06:15] <Tom_itx> heh
[07:06:28] <ries> jthornton: or for making insets... I am not doing it, I am just wondering what to think of...
[07:07:03] <jthornton> 0.01mm is pretty small at 0.0004"
[07:07:50] <ries> that's like 10um, I remember I bought milar for my ESL's that was 10um, pretty thin stuff...
[07:07:58] <ries> Just wondering..
[07:08:57] <dgarr> engrave text on cylinder: http://woodturning.pastperfect-online.com/36471cgi/mweb.exe?request=image&hex=2008DG102-5.JPG
[07:09:49] <jthornton> nice
[07:11:01] <ries> that's indeed nice..
[07:18:56] <dgarr> xzc machine x:15000cts/in,z:56000cts/in,c:20 cts/deg
[07:22:37] <dgarr> (the x&z resolutions are much higher than needed for this size)
[07:37:35] <archivist_herron> the rpm of the cutter can/should be taken into account when deciding what resolution you are getting
[07:57:29] <Tom_itx> how do you calculate the surface speed for an engraving cutter since it comes to a point?
[07:58:01] <Tom_itx> the diameter at the material plane?
[08:38:19] <JT-Shop> nothing is moving today in swamp east Missouri
[08:39:26] <JT-Shop> just had to rescue my wife, she didn't make it far
[08:40:45] * JT-Shop wishes he had put the grader blade on the tractor yesterday :(
[11:59:59] <archivist> bit quiet for a Friday.....
[12:12:15] <IchGuckLive> hi all B)
[12:22:38] <Tasab> hi all
[12:23:34] <Tasab> who can hlp how to change from language to language (keyboard shortcut) debian ver - tks
[12:24:16] <IchGuckLive> for linuxcnc
[12:24:26] <IchGuckLive> what woudt you like to change
[12:25:28] <Tasab> i installed 2 langs en and fr , would like the keyboard shortcut - tks
[12:25:49] <ReadError> maybe he just searched for linux and found this
[12:27:51] <IchGuckLive> we use ubuntu as a distro but you can change the shortcuts under the system language
[12:29:22] <IchGuckLive> also in the System Entrys Keyboardshortcuts as ubuntu got this
[12:51:14] <ju-emb> IchGuckLive: It's friday so you come early out of the UNI and on your computer
[12:56:36] <IchGuckLive> no
[12:56:47] <IchGuckLive> std time
[14:30:40] * Tom_itx puts another log on the fire
[14:42:11] * Loetmichel is just testing his new PC by bitcoin mining... no need for a log on the fire: room is cozy warm now ;-) (I3-3.4GHz, 550W PSU, ATI HD 7870) -> 68┬░C air from the PSU exhaust and 74┬░C air from the GPU slot exhaust ;-) and the PSU draws 450W from the line ;-)
[14:42:36] <Loetmichel> i think this is called "BURN IN TEST" ;-)
[14:42:53] <FinboySlick> Loetmichel: If it's solo-mining, you could get lucky and get 25 bitcoins ;)
[14:43:02] <Loetmichel> no, pooling
[14:43:37] <FinboySlick> Loetmichel: Are blocks still at 25 coins now or have they dropped to 12?
[14:43:39] <Loetmichel> i am not the guy for Lucky.
[14:43:53] <Loetmichel> iirc 25BTC per bloc
[14:44:06] <Tom_itx> can you spend em at walmart?
[14:44:18] <Tom_itx> i don't do bitcoin
[14:44:27] <Tom_itx> seems kinda silly
[14:44:30] <Loetmichel> but wiht the ~450MH/sec i cant hope ti get anywhere a complete block before being stale...
[14:44:32] <FinboySlick> Tom_itx: Heh, I sort of wish I did.
[14:44:59] <Loetmichel> not at difficulty 707408283
[14:45:04] <Loetmichel> :-)
[14:45:04] <FinboySlick> I looked into it back when you could do plain CPU mining.
[14:45:12] <FinboySlick> And thought, "Nah, too complicated."
[14:45:30] <FinboySlick> Now I sort of wish I had 1000 bitcoins lying around.
[14:45:43] <Loetmichel> btw: gpu does 450Mh/s... cpu does 0,5Mh/s ;)
[14:46:33] <FinboySlick> Loetmichel: When I looked into it, GPU mining hadn't taken off yet.
[14:47:56] <Loetmichel> and the pool i'm in has 350Gh/s at hand and still only makes a block every 2hours or so ;-)
[14:48:28] <Loetmichel> so: nowwhere near rentability to mine with the gpu... has to use asics to be profitable there
[14:48:58] <Loetmichel> but its a great stress test for a new system to drive iot to the edge while still warranty on the parts ;-)
[14:58:13] <FinboySlick> Yo Andy.
[14:59:00] <FinboySlick> Oh damn, now I have Les Rita Mitsouko playing in my mind.
[14:59:36] <Loetmichel> who's that?
[15:00:02] <FinboySlick> http://www.youtube.com/watch?v=FG4U-UTzSHM 80's french pop band.
[15:00:38] <FinboySlick> Lead singer apparently also had a career as a hardcore porn star :P
[15:00:53] <Loetmichel> FinboySlick: "sorry, gema doesnt want you to see this"
[15:00:59] <Loetmichel> <- german... :-(
[15:01:15] <FinboySlick> Loetmichel: Hahaha, seriously?
[15:01:35] <Loetmichel> qoute youtube: "
[15:01:36] <Loetmichel> Leider ist dieses Video, das Musik von EMI beinhaltet, in Deutschland nicht verf├╝gbar, da die GEMA die Verlagsrechte hieran nicht einger├Ąumt hat.
[15:01:36] <Loetmichel> Das tut uns leid.
[15:01:36] <Loetmichel> "
[15:01:36] <FinboySlick> Copyright or censor?
[15:01:43] <FinboySlick> Ah, okay, copyright.
[15:02:26] <andypugh> Loetmichel: I get that a lot at work. Which is especially annoying because I am not in Germany.
[15:02:59] <Loetmichel> andypugh: you work for a german company?
[15:03:00] <Loetmichel> ;-)
[15:03:02] <FinboySlick> Loetmichel: You're not missing much in that case, it's a weird song from an even weirder band.
[15:03:16] <andypugh> Loetmichel: Not really. Ford.
[15:03:23] <Loetmichel> hmm, strange
[15:03:44] <FinboySlick> andypugh: Are you the one who took the v6 out of the Fusion? ;)
[15:03:46] <Loetmichel> i thought maybe you have a german internet connection because the company headquartes is in germany
[15:05:07] <andypugh> Loetmichel: It is something like that. But as Ford is a Class 1 (19.xx.xx.xx) I don't know how they try to figure it out.
[15:05:41] <andypugh> FinboySlick: No, nor am I the one that put the Ecoboost in the Mustang.
[15:06:07] <FinboySlick> andypugh: If they have regional subnets in that range, they can provide a location for each in the ARIN database.
[15:06:48] <FinboySlick> I kind of wish my Fusion had ecoboost. But then I'd have the same engine as the SHO Taurus.
[15:07:05] <FinboySlick> And I doubt my transmission would survive.
[15:07:23] <FinboySlick> Though they sort of did that in the Flex and we share a transmission... Who knows.
[15:08:05] <Loetmichel> FinboySlick: hrhr
[15:08:21] <Loetmichel> i drive an Opel Omega 2,5 liter 6cyl diesel
[15:08:26] <Loetmichel> automatic gearbox...
[15:09:08] <FinboySlick> Loetmichel: That doesn't sound entirely bad.
[15:09:11] <Loetmichel> and i can hear the prop shaft going "KNOCK" at every load change
[15:09:12] <Loetmichel> ;-)
[15:09:32] <FinboySlick> You probably aren't short on torque.
[15:09:48] <Loetmichel> ... must be the rubber disc that dampens the load changes
[15:09:54] <Loetmichel> not really
[15:10:56] <Loetmichel> have pulled a 7,5 ton lorry from the autobahn to the car workshop lately
[15:11:02] <Loetmichel> -> no problem
[15:11:23] <FinboySlick> That too might explain a knock in your transmission :P
[15:11:46] <Loetmichel> althoug ist s a strange sight seeing a saloon pullong a Truck ;-)
[15:12:15] <Loetmichel> no, that sound is there exactly since the worhshop has changed my back brake discs
[15:12:23] <Loetmichel> i think the have done something wrong then
[15:12:39] <Loetmichel> they
[15:14:16] <Loetmichel> FinboySlick: my car: http://www.spritmonitor.de/de/detailansicht/442560.html
[15:15:37] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11969 <- better view
[15:16:04] <Loetmichel> and its rear drive, like it should be ;-)
[15:16:27] <Loetmichel> (and the ASR can be deactivated ;-)
[15:23:02] <Loetmichel> already made some donuts by accident ( slightly wet street, cheap tyres, lead foot at the traffic lights... -> 360┬░ turn with the front wheels still at the thraffic light line ;-)
[15:30:47] <FinboySlick> Loetmichel: I remember seeing that car before. It's very nice to have a car you love... I'm about the same with my Fusion.
[15:31:38] <Loetmichel> its simply a very comfotable saloon/hatchback with unbelieveable vast storage room inside
[15:32:55] <Loetmichel> when i flip the rear seats i have about 2,05m by 160cm by 80cm volume with a flat bottom and very low, too.
[15:51:23] <FinboySlick> Loetmichel: Maybe you could get the granite slab that archivist mentioned before.
[15:51:59] <FinboySlick> Neat way to one-up the truck pulling challenge.
[15:52:20] <Loetmichel> hrhr
[15:53:06] <FinboySlick> Suspension might pop more than your transmission.
[16:01:34] <JT-Shop> a good day to run the powder coat oven... it snowed so much the back of my pickup truck is full to the top with snow
[16:12:08] <Loetmichel> FinboySlick: suspensuon is good for an additional 1.5 metric tons ;-)
[16:12:11] <Loetmichel> in the back
[16:14:50] <MacGalempsy> it is strange that since going on vacation, unplugging the machine, then coming back and plugging it in does not power up the 7i77 :(
[16:14:54] <skunkworks> I carried this around for the longest time as a good luck charm..
[16:14:58] <skunkworks> http://electronicsam.com/images/KandT/testing/ouch.JPG
[16:15:16] <skunkworks> http://electronicsam.com/images/KandT/testing/ouch1.JPG
[16:15:19] <MacGalempsy> how is that lucky?
[16:16:20] <FinboySlick> MacGalempsy: Bt the look of things, it's lucky it didn't do more damage ;)
[16:16:36] <MacGalempsy> ha. yes, agreed
[16:18:08] <skunkworks> it few across the room...
[16:18:13] <skunkworks> flew
[16:18:58] <FinboySlick> skunkworks: What's the smear around the endmill/drill.
[16:19:31] <FinboySlick> Chuck rubbed on it?
[16:19:35] <skunkworks> yes
[16:19:42] <skunkworks> it was a centering drill
[16:20:17] <skunkworks> I inverted x and z iirc
[16:20:20] <FinboySlick> I'll keep it in the back of my mind as a goodluck charm/warning too.
[16:20:53] <FinboySlick> But it's 5pm, friday and time for me to go do as little as possible for a while ;)
[16:51:15] <Deejay_> gn8
[17:10:03] <andypugh> Loetmichel: My car :-) http://images.thecarconnection.com/lrg/2013-ford-fusion-mondeo-spy-shots_100368694_l.jpg
[17:13:28] <andypugh> in other news, my Y-axis upgrade now makes my X look bad. Is there no end to the expense?
[17:13:44] <JT-Shop> lol
[17:14:06] <Loetmichel> andypugh: had to much black tape and cloth?
[17:14:16] <andypugh> I have 0.03mm backlash in the Y. That's not brillliant, I accept, but is probably pretty good for a retrofit from leadscrews.
[17:14:17] <Loetmichel> (thats called an "erlkoenig" in germany ;-)
[17:16:08] <andypugh> (www.loe.dict) Ah, yes, that is exactly what it its.
[17:16:28] <andypugh> Err. www.leo.dict
[17:16:52] <andypugh> Luckily the forst one isn't anything dodgy.
[17:19:12] <andypugh> I once trashed a company PC. I was looking for info on large marine diesels and tried www.man.com. I found a web site that catered to specialised interests, but also one that spawned new windows on mouseover. I couldn't close them as fast as they were opening, and a number of horrible things got installed. (this was windows XP a long time ago). I had to reinstall windows from scratch.
[17:20:29] <andypugh> (that URL is now safe, by the way, bit still isn't about diesel engines)
[17:26:04] <jdh_> a friend got a ford Fusion energie or something like that the other day
[17:28:33] <andypugh> The Fusion has been out for quite a while in the US, it is due to launch as the new Mondeo in the UK next year.
[17:28:59] <andypugh> (And the rest of Europe).
[17:29:03] <jdh> he got the plug-in hybrid
[17:29:17] <andypugh> Does he like it?
[17:29:56] <jdh> he hasn't used any gas all week
[17:30:12] <andypugh> I haven't tried one, I work on diesels, bit I can't see diesel as the long-term future. They can be very efficient, but they can't be very efficient and low in NOx.
[17:30:57] <andypugh> My personal opinion is that NOx limits are too low, and it would be better to relax them and chase fuel efficiency.
[17:35:48] <kengu> but nox is bad, they say.
[17:36:48] <andypugh> It's bad in Beijing, it's awful in LA. Those places could have their own rules.
[17:42:37] <CaptHindsight> the sulfur ratings for diesels in the US must have just been set to insure that low efficiency cars stay on the roads here (good for the oil co's)
[17:44:01] <JT-Shop> snow finally stopped, now to get the tractor to start tomorrow and blade the driveway
[17:48:27] <CaptHindsight> JT-Shop: how much snow did you get? I heard it's on the way up here
[17:49:54] <jdh> it was 75F and sunny here today.
[17:56:22] <JT-Shop> we got enough to fill the bed of my full size pickup truck
[18:13:39] <Jymmm> JT-Shop: selling snow cones now?
[18:14:11] <Jymmm> JT-Shop: Wait, how the hell do you have snow in swamp country?
[18:15:08] <JT-Shop> it ain't swampy today
[18:15:33] <Jymmm> Do the gators have snow shoes on?
[18:21:25] <JT-Shop> no gators here only grinnell's
[18:22:08] <Tom_itx> swamp must be froze over
[18:53:16] <JT-Shop> time for me to slip slid inside
[20:42:32] <jesseg> howdy Folks
[21:59:48] <NickParker> Ok I only get these two warnings when I generate my programming file now: http://pastebin.com/bK5QiG8d
[22:00:17] <NickParker> The first one sounds kind of ominous and prone to bricking my card though. do you know why these would come up pcw_home?
[22:11:36] <uw> HOWDY JESSEG
[22:12:50] <jesseg> Hi there uw
[22:16:27] <uw> hello
[22:21:39] <NickParker> ok seems I don't brick it anymore, but now I'm turning all my pins into IOports for some reason
[22:49:55] <WalterN_bed> CaptHindsight: you ever hear of SLS with an amorphous metal?
[23:00:31] <CaptHindsight> WalterN_bed: http://www.macrumors.com/2013/07/17/apple-liquidmetal-collaboration-awarded-patent-on-process-for-mass-production-of-amorphous-metals/
[23:02:04] <WalterN_bed> CaptHindsight: I'm thinking more generic, rapid prototyping style
[23:03:09] <WalterN_bed> just wondering if you have heard of it before, or if there is a reason nobody else seems to be doing it
[23:04:33] <CaptHindsight> patents
[23:04:51] <WalterN_bed> ..?
[23:06:14] <CaptHindsight> the current system lets the holders sit on them, even if they don't make anything with them, so control has priority over the advancement of tech and science
[23:11:36] <WalterN_bed> CaptHindsight: think its worth perusing?
[23:13:41] <WalterN_bed> I would think amorphous metal would be a very desirable thing, esp. if it could be SLS'd into parts
