[03:50:25] <Loetmichel> mornin'
[03:51:53] <alex_joni> mornin'
[03:52:08] <alex_joni> any UK'ers around?
[03:52:36] <archivist> yer
[03:52:59] <alex_joni> howdy archivist
[03:53:10] <archivist> allo
[04:01:20] <archivist> alex_joni, but.. a meetup at http://www.modelengineershow.co.uk/
[04:03:47] <alex_joni> archivist: interesting
[04:04:21] <alex_joni> (if it would load, it would be even more interesting)
[04:04:58] <archivist> the important part The 2012 Model Engineer Exhibition will be held at Sandown Park Racecourse in Esher, Surrey, on 2nd, 3rd and 4th November 2012
[04:05:13] <alex_joni> well, I'm there 3 weeks later
[04:05:22] <archivist> come early
[04:05:27] <alex_joni> ha
[04:44:41] <findux> hi how to get Axis ui referans
[05:24:02] <jthornton> he didn't stay long
[05:24:19] <Valen> most people dont
[05:24:30] <Valen> of that i'm a little glad
[05:25:02] <mhaberler> how do I rebuild the 2.6.32-122-rtai kernel included in the liveCD from source? cant find the kernel source package
[05:29:42] <micges> I think easiest way is to make them from scratch
[05:34:57] <micges> s/easiest/fastest
[05:35:06] <micges> I didn't found it too
[05:39:34] <micges> mhaberler: http://www.linuxcnc.org/lucid/dists/lucid/base/source/
[05:39:58] <mhaberler> oh, ah. thanks!
[06:28:58] <alex_joni> mhaberler: apt-get source
[06:29:04] <alex_joni> should always work
[06:29:17] <alex_joni> for any deb package
[06:33:27] <mhaberler> ok, in full glory it's:
[06:33:29] <mhaberler> apt-get source rtai-modules-2.6.32-122-rtai
[06:33:29] <mhaberler> apt-get source linux-image-2.6.32-122-rtai
[06:33:32] <mhaberler> thanks!
[07:03:03] <alex_joni> mhaberler: np
[08:28:37] <jthornton> is this basic enough for someone new to ladder? http://gnipsel.com/linuxcnc/ladder/basic.html
[08:31:13] <archivist> hmm "What happens after the logic is updated the last output state will be the state that is written to the output."
[08:31:19] <Jymmm> JT-Shop: Two items stick out: 1) Missing Intro; What is/does Ladder do? 2) Why not --> Avoid using Latch and Unlatch, instead use a seal-in circuit.
[08:32:42] <jdh> does classic ladder have one-shots?
[08:34:00] <Jymmm> JT-Shop: 3) How do I make a comment?
[08:50:45] <JT-Shop> jdh: if by one shots you mean rising edge or falling edge yes
[08:51:12] <JT-Shop> Jymmm: If they don't know what ladder does they don't need to read that page :)
[08:51:25] <JT-Shop> cause I said so
[08:51:32] <JT-Shop> comment where?
[08:51:55] <jdh> if you have a rising edge setting a mem bit, will the rung above that ever see the output mem bit?
[08:52:05] <Jymmm> JT-Shop: Any; like what it does, why this does something, etc.
[08:52:53] <ScribbleJ> I've got my water-cooled laser and spindle out in the garage and temperatures are getting pretty low outside. Should I be running antifreeze or something in them or try to purge all the water with air, or what?
[08:54:18] <Jymmm> ScribbleJ: There is such a thing as "Food Grade Glycol", but you should check/verify it's temp ratings.
[08:55:11] <Jymmm> ScribbleJ: Else, you could use a small heat source. Even a 40W lightbulb (not CFL) could do the trick.
[08:55:12] <JT-Shop> a rising edge will be on for one scan
[08:55:38] <JT-Shop> Jymmm: ?
[08:55:44] <jdh> JT: one scan until it gets back to the current rung, or one scan until it gets to the last rung?
[08:55:48] <ScribbleJ> Is there a reason to prefer food grade pg over automotive antifreeze?
[08:56:04] <ScribbleJ> Would I run 100% pg/antifreeze in or use a mix with water?
[08:56:09] <Valen> I'd run some kind of antifreze
[08:56:10] <JT-Shop> a scan is read inputs, solve logic, update outputs
[08:56:17] <Valen> if its compatible with your stuff
[08:56:24] <Jymmm> ScribbleJ: antifreeze is a poison to animals/kids, Food Grade isn't.
[08:56:29] <jdh> so the rung above it would never see the output turn on.
[08:56:35] <ScribbleJ> Good point, Jymmm
[08:56:43] <Valen> we run antifreze in our spindle, mainly because dissimilar metals are an issue
[08:56:52] <Valen> its only "toxic" if you drink the stuff
[08:57:10] <jdh> it is supposed to taste good to dogs anyway
[08:57:14] <Jymmm> Valen: But antifreeze is sugary sweet, and that's why animals drink it.
[08:57:24] <JT-Shop> a scan reads all of the input states, solves all of the logic, then updates all of the outputs
[08:57:32] <JT-Shop> it's not done one line at a time
[08:57:36] <Valen> have you tasted a proper antifreze?
[08:57:48] <Jymmm> Valen: Me? Yes.
[08:57:50] <Valen> with all the corrosion inhibitiors mixed up at 25%?
[08:58:02] <Valen> its not something I'd taste again on purpose
[09:01:10] <jdh> I think I have seen different behavior for one-shots in GE/Fanuc Series 6
[09:01:18] <Jymmm> ScribbleJ: If you are near a winery, they usually have Food Grade Glycol by the 55gal barrels, so you might be able to grab a gallon or two if you bring some screw-top gallon jugs.
[09:02:07] <ScribbleJ> I don't believe I am. But it sounds like something I could find at a hardware store.
[09:02:10] <Valen> you want to have a corrosion inhibitor as well or disimilar metal corrosion will eat stuff really fast
[09:02:14] <JT-Shop> or go to wally world and get it by the camper supplies near automotive
[09:02:25] <ScribbleJ> Corrosion inhibitor?
[09:02:35] <Valen> do you often have children trying to drink from your laser?
[09:02:47] <Valen> there is a reason you don't fill your car engine with tap water
[09:02:49] <JT-Shop> glycol = holding tank antifreeze
[09:03:16] <Valen> if you have 2 different metals and water in the path it will cause one of the metals to plate onto the other (basically)
[09:05:23] <ScribbleJ> Do I just look for a product called "corrosion inhibitor" or is there something in particular?
[09:05:42] <Valen> thats why i use radiator mix
[09:05:54] <Valen> like $5 for 5L and its fine
[09:05:59] <ScribbleJ> All right.
[09:06:02] <Valen> just check the minimum temp
[09:06:12] <Valen> and don't let children drink lots of it
[09:06:25] <Valen> btw don't fill your car with tap water lol
[09:06:39] <Valen> use de-ionised water, you can get it for like $2 for a 4L jug
[09:06:41] <ScribbleJ> I guess I shuld remove the "DELICIOUS KOOL-AID" sticker from my coolant reservoir.
[09:06:54] <Valen> got children?
[09:07:04] <Jymmm> ScribbleJ: Might look at the label on this http://www.walmart.com/ip/Swim-Time-One-Quart-Anti-Freeze-Concentrate/20966402
[09:07:48] <Valen> you haven't mentioned corrosion though with these antifrezes
[09:08:02] <Valen> if he has brass fittings and an Al radiator it'll eat the radiator
[09:08:17] <ScribbleJ> I don't have the slightest idea what is inside my spindle where the water goes.
[09:08:25] <Jymmm> Valen: It's for his LASER, not car.
[09:08:26] <ScribbleJ> The laser is probably safe though, it seems to be all glass.
[09:08:34] <ScribbleJ> Jymmm, laser and mill spindle.
[09:08:47] <Valen> Jymmm: does that stop corrosion?
[09:09:06] <Valen> lasers make all the attached hardware immune
[09:09:10] <ScribbleJ> Valen, I'm not sure there's anything in the laser to corrode really - the water path appears to be all glass.
[09:09:17] <Jymmm> Valen: If he uses distilled water, then yes.
[09:09:41] <Valen> he needs deionised not distilled
[09:09:48] <Jymmm> Why?
[09:10:10] <ScribbleJ> Because it's the neg/pos ions (salts) in the water that cause corrosion?
[09:10:27] <Jymmm> distilled doens't have any salts.
[09:10:38] <ScribbleJ> That's what I'd guess. I know nothing.
[09:10:46] <Valen> corrosion happens through galvanic action
[09:10:52] <Valen> ions are charge carriers
[09:11:22] <Jymmm> Valen: with interaction with metal; but if there is no metal in his laser...
[09:11:22] <Valen> deionised water has that largley removed, distilled is more concerned with other crap
[09:11:39] <Valen> what about his radiator? and pump, and fittings, and mill spindle
[09:11:45] <ScribbleJ> Jymmm, OK, but the mill spindle!
[09:11:51] <ScribbleJ> Oh, the pump, good point there.
[09:12:04] <Jymmm> ScribbleJ: I believe his radiators is a 5gal plastic bucket
[09:12:06] <ScribbleJ> I don't really have a radiatior, it's just a 5gal bucket.
[09:12:12] <ScribbleJ> Yes. :(
[09:12:12] <ScribbleJ> heheh
[09:12:34] <ScribbleJ> Because I'm made of awesome.
[09:12:38] <Jymmm> err Valen I meant
[09:13:34] <Valen> if your going to spill it, use DI water and blast air through
[09:13:47] <Valen> otherwise get a car radiator and use that ;->
[09:13:55] <Valen> I got mine for like $20
[09:19:44] <Valen> ScribbleJ: like our setup? http://www.vapourforge.com/cnczone/hm45/PB_Head/end_result/overall.jpg
[09:19:48] <Valen> classy all the way
[09:20:08] <Valen> (it has gotten rather better since then, but it shows the cooling setup)
[09:22:22] <Valen> we found the pump on the side of the road
[09:22:35] <Valen> $10 in parts and blam fancy coolant pump lol
[09:30:04] <JT-Shop> jdh: yea, I've seen slightly different behaviours in various PLC's but this is strictly for ClassicLadder
[09:30:45] <ScribbleJ> Valen... wow, uh.
[09:31:39] <Valen> lol it looks like crap
[09:31:56] <Valen> but those are OH&S approved shower curtains for the chip catcher lol
[09:32:29] <Valen> the "safety screen" rather
[09:40:59] <archivist> Valen, dunno who wins the fugly contest...you or me :)
[09:41:18] <Valen> i said it looks better now ;-P
[09:41:34] <Valen> and don't go hating on our head
[09:41:41] <Valen> it works rather well in fact
[09:42:14] <archivist> fugly tends to work, I never said anything about hatin
[10:05:30] <mrsun> Valen, that mill head ... <3
[10:05:45] <mrsun> looks like something out of like 2200 the year we made contact or something :P
[10:06:01] <Valen> i'm guessing thats a horror movie?
[10:06:24] <Valen> http://www.cnczone.com/forums/general_metal_working_machines/118358-phenolic_basalt_head_our_hm45.html if you want to see the history of building that head btw
[10:07:52] <mrsun> Valen, dont know :P sounded good .. like something like steampunk :P
[10:08:04] <Valen> lol
[10:08:16] <Legonilsson> Is there anyone in Sweden who has built or rebuilt a machine with LinuxCNC?
[10:08:20] <Valen> well our next mill should be damn sexy
[10:08:37] <Valen> we are making a skin of stainless steel, then back filling it with the stuff we made the head out of
[10:08:40] <mrsun> oh its made in epoxyconcrete ?
[10:08:57] <Valen> well vinyl ester and road base but the same ide
[10:09:02] <Valen> just 10% of the price ;->
[10:09:29] <Valen> i might have to polish the stainless ;->
[10:13:01] <Legonilsson> I have a Lathe from -83 with some kind of mixed up control from Fanuc and Siemens. The lathe is in good condition. So I'd like to rebuilt it wit a new control. I'm prepared to pay for it.
[10:14:05] <Legonilsson> Has anyone compared Mach3 and LinxCNC?
[10:14:47] <Valen> probably asking that in the wrong room lol
[10:14:53] <Valen> mach vs linuxcnc
[10:16:27] <archivist> Legonilsson, for a start for screw cutting there is no comparison, linuxcnc works :)
[10:16:59] <archivist> which for a lathe is rather important
[10:17:56] <Valen> kinda the point of them really
[10:18:14] <Legonilsson> Sorry it wasn't my meantion to upset anyone.
[10:18:58] <Valen> lol we aren't upset
[10:19:05] <Valen> but you may get a biased answer ;->
[10:19:06] <JT-Shop> I attempted to use Mack once...
[10:19:19] <FinboySlick> I'd guess Mach is a bit less flexible in terms of setup too. It's tailored to a few specific types of machines. I doubt it could run a hexapod but I could be wrong.
[10:19:47] <jdh> does anyone use a hexapod for anything?
[10:20:08] <micges> heh for testing kinematics maybe :)
[10:20:10] <FinboySlick> jdh: They make cool pick and place robots.
[10:20:11] <jdh> I bet mach can't run a dodecahedropod.
[10:24:41] <micges> Legonilsson: what's name of this lathe?
[10:24:59] <jdh> I call mine "Daisy"
[10:27:05] <micges> :)
[10:31:21] <archivist> my MD65 lathe had some choice names not repeatable in public
[10:49:14] <Legonilsson> It's a Storebro 260
[10:49:43] <archivist> were you in here a while ago asking about this machine
[10:50:33] <archivist> http://comments.gmane.org/gmane.linux.distributions.emc.user/35033
[10:50:51] <archivist> april, the old memory still works :)
[10:51:05] <Legonilsson> Not me, but a friend that should help me with this machine
[10:52:24] <archivist> ok so same machine :)
[10:54:16] <Legonilsson> I have 8 lathes with Siemens and 1 lathe with Fanuc, I have 2 MVC with Fanuc. Is it hard to learn LinuxCNC?
[10:54:41] <Legonilsson> yes, it's the same machine
[10:55:01] <awallin> wow Legonilsson has a big garage :)
[10:55:35] <Legonilsson> It's my living,
[10:56:49] <awallin> you probably want to take it slow and learn things when setting up and cofiguring the first machine
[10:57:13] <awallin> using linuxcnc is easy, I'd say just minor new routines to learn compared to a commercial control
[10:59:39] <Legonilsson> Where do I start? I'm good at milling, drilling, turning, welding but I'm not so good at computers.
[11:00:15] <awallin> are these servo-machines? with +/-10V analog control? you will need some hardware in the pc
[11:00:27] <awallin> and you need to start with a pc that has decent real-time performance
[11:01:19] <awallin> you can probably boot from the live-cd and run latency-test, without installing anything. I think..
[11:01:48] <Legonilsson> Were do I get the live-cd?
[11:02:09] <awallin> read http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC
[11:03:07] <awallin> that points us here http://linuxcnc.org/index.php?option=com_content&task=view&id=21&Itemid=4&lang=en
[11:06:12] <Legonilsson> I'm downloading the ISO is that correct?
[11:07:02] <awallin> yes, then burn that to CD. there might also be a way of writing it to an USB-stick, if your motherboard/bios can boot from usb-stick.
[11:11:10] <Legonilsson> It seem's like I will spend some time on this chat
[11:12:34] <Legonilsson> Is there anyone in Sweden who has built or rebuilt a machine with LinuxCNC?
[11:19:14] <tjb1> JT-Shop: Are you firing torch with M3?
[11:19:30] <JT-Shop> yea iirc
[11:20:01] <tjb1> How do you add the arc ok ?
[11:20:06] <JT-Shop> S1M3
[11:20:17] <JT-Shop> digital input
[11:20:29] <tjb1> I mean how do you get that into the program so it wont start until it gets that
[11:20:42] <awallin> Legonilsson: try anders over here http://www.almaskin.se/
[11:20:48] <JT-Shop> digital input
[11:21:09] <JT-Shop> http://linuxcnc.org/docs/html/gcode/m-code.html#_m66_wait_on_input_a_id_sec_m66_input_control_a
[11:21:40] <tjb1> Ok thanks
[11:22:37] <Legonilsson> I'll try that! Thanks
[11:23:16] <JT-Shop> tjb1: http://gnipsel.com/shop/plasma/files/touchoff.ngc
[11:24:19] <tjb1> Are you using a floating Z with switch?
[11:24:49] <JT-Shop> yes connected to the probe input
[11:25:23] <tjb1> That the M38
[11:25:51] <tjb1> Err g38
[11:26:11] <JT-Shop> yep http://linuxcnc.org/docs/html/gcode/gcode.html#_g38_x_straight_probe_a_id_sec_g38_probe_a
[11:27:42] <tjb1> Ok and I dont plan on getting mesa cards for thc, I am going to monitor and adjust voltage with an arduino and just have 2 outputs from it, torch up and torch down
[11:28:29] <tjb1> I looked over your THC setup and im guessing I can just use most of it like currentvel and setvel and just have it so it ignores the outputs when under a certain velocity
[11:28:38] <tjb1> But what do you do when you cross over a cut area?
[11:31:14] <tjb1> Thats my final problem with THC :)
[11:31:37] <JT-Shop> you don't
[11:32:56] <tjb1> You just hope it is moving fast enough eh?
[11:34:25] <JT-Shop> ??
[11:34:58] <tjb1> Does drop at all crossing the kerf?
[11:35:25] <JT-Shop> you don't cross the kerf
[11:35:38] <JT-Shop> that's poor programming
[11:35:49] <tjb1> Lead in lead outs
[11:36:38] <JT-Shop> I keep my lead outs very short and for lead in's it doesn't matter you havn't cut the kerf yet
[11:37:16] <tjb1> If I have a problem I guess I will program it into the arduino to ignore rapid voltage changes
[11:45:06] <tjb1> Care to share your HAL file so I can see how you set it up? :)
[11:45:25] <JT-Shop> http://gnipsel.com/shop/plasma/plasma.xhtml
[11:46:43] <tjb1> Oh wow, you are awesome
[11:47:44] <JT-Shop> just an ordinary redneck
[11:48:31] <tjb1> Heh.
[11:48:47] <jdh> nah, an awesome redneck!
[12:07:15] <IchGuckLive> Hi all around the world
[12:08:37] <andypugh> Hi
[12:09:02] <Connor> Any recommendations on a good coolant ?
[12:09:14] <Connor> Looking at this stuff.. http://www.littlemachineshop.com/products/product_view.php?ProductID=4119&category=
[12:10:12] <andypugh> That sounds useful for hobby use, where it is likely to spend a lot of time in the tank
[12:10:19] <andypugh> multi-metal is also good.
[12:10:45] <Connor> What do you do, mix it with tap water or distilled water ?
[12:11:04] <andypugh> It is generally difficult to buy small quantities of coolants, so there is only a limited choice
[12:11:18] <andypugh> Tap water, generally.
[12:12:02] <Connor> http://www.harborfreight.com/6-1-2-half-gallon-parts-washer-96952.html
[12:12:06] <Connor> I've got one of those comming.
[12:12:27] <tjb1> Connor: How do you like the C10?
[12:12:41] <Connor> tjb1: It works just fine.
[12:13:03] <tjb1> Good :)
[12:13:07] <andypugh> I have heard that Castrol Clearedge is good, but I have never found it in a small enough quantity to try. Also, none of my machines have coolant at the moment.
[12:20:08] <archivist> similar problem with corrosion protection oil min qty is 20 litres
[12:21:09] <archivist> should I get some and sell small qty on, type is ensis RPO 1200
[12:22:41] <andypugh> You can probably offload at a profit on eBay
[12:23:32] <archivist> dunno what the delivery vat etc will cost yet
[12:23:45] <archivist> I need profit at the moment!
[12:24:39] <andypugh> I can't help feeling that Waxoyl might work equally well.
[12:25:21] <archivist> dont want the wax type as that has to be cleaned before use
[12:25:49] <andypugh> Waxoly isn't particularly waxy.
[12:26:09] <archivist> there is a wax grade of ensis the local steam engine lived for 20 plus years coated in it
[12:26:17] <andypugh> (I am referring to the stuff you are meant to spray inside the sills of 1980s cars)
[12:26:40] <archivist> they needed it inside and out!
[12:27:04] <archivist> my mundano is rotting
[12:28:09] <andypugh> How old is it? I read a 1970s "long term test" that was discussing corrosion and paint-bubbling on brand-new cars after 12 months.
[12:30:23] <archivist> 12 years old
[12:30:36] <L84Supper> andypugh, did it mention the brand of auto or the type of paint used?
[12:30:59] <L84Supper> waterborne urethanes perhaps?
[12:31:18] <archivist> L84Supper, the design life in the 1970s was short! all makes as far as I know
[12:31:57] <andypugh> The cars were, IIRC a Ford Capri, Vauxhall (something), Alfa Romeo (something) and another I have completely forgotten.
[12:32:13] <archivist> I have internal slides from Lucas from the period about dynamo failure rates
[12:32:14] <L84Supper> archivist, oh year 70's cars, I was wondering if the article mentioned the new cars that were bubbling in 12 months
[12:32:49] <andypugh> The cars were only "brand new" at the time the article was written.
[12:33:22] <L84Supper> andypugh, sorry, i get it now :)
[12:34:01] <archivist> not scanned and documented all yet http://www.collection.archivist.info/searchv13.php?searchstr=lucas+failure+rate
[12:34:33] <L84Supper> Ford Metallic enamels would fade to red primer up to the 80's
[12:35:34] <archivist> red is problem colour anyway
[12:36:24] <L84Supper> the silvers were the worst

[12:40:09] <archivist> jaguar engine rectification records are entertaining
[12:46:47] <L84Supper> http://skycnc.en.made-in-china.com/product/gBAJONoKEnhe/China-High-Precision-5-Axle-Machining-Centre-SK-5L116075-.html not exactly the best accuracy and repeatability specs
[12:47:18] <L84Supper> I wonder how inexpensive they
[12:47:22] <L84Supper> are
[12:48:16] <jdh> anyone ever use Parker/Compumotor A-series stepper drives? I just tossed 16 of them.
[12:48:58] <L84Supper> I've only used their servos
[12:52:38] <andypugh> Most Parker stuff seems pretty good.
[12:52:41] <archivist> I have Parker stepper drives in the old Denford, just L297 L298 really
[12:52:53] <archivist> I had to repair one
[12:53:20] <jdh> these take 120vac, do microstepping, 3 amps max.
[12:53:39] <andypugh> L84Supper: 0.008mm sounds plenty good enough to me
[12:54:24] <L84Supper> andypugh, if the spec is metric I'd agree
[12:54:49] <andypugh> It says 0.008/300mm
[12:55:18] <L84Supper> 8 microns over 300mm
[12:56:39] <L84Supper> what was i thinking
[12:57:19] <jdh> these look like they would be at least as good as cheap chinese drivers, and not require a separate PS.
[13:00:34] <L84Supper> jdh: http://www.artisan-scientific.com/itemimages/Compumotor_AL_Drive_120826_View1.JPG these?
[13:02:49] <jdh> yep.
[13:03:23] <L84Supper> I found a pic but haven't found the specs yet
[13:04:34] <jdh> http://www.artisan-scientific.com/info/Compumoter_A_Series_Manual.pdf
[13:05:41] <L84Supper> http://www.parkermotion.com/manuals/A-AX/A-AX.htm
[13:09:02] <L84Supper> the Parker drives tend to have nice big heatsinks and lots of programmable protection circuitry (overcurrent, high temp, etc)
[13:09:28] <jdh> the whole top half of the case is a giant heat sink
[13:09:45] <jdh> has an AMD cpu of some sort in it.
[13:11:11] <jdh> too bad nobody can officially just let me take them home. Instead, we pay to dispose of them as hazardous material.
[13:11:43] <archivist> get a disposal licence the you get paid
[13:13:32] <archivist> I had one for a while to be able to go to .gov auctions and get "stuff"
[13:15:02] <L84Supper> there's a place near Chicago that's a licensed recycler, they end up with tons of perfectly fine automation equipment and controllers, they used to scrap it until they realized that they could just resell it used
[13:16:37] <L84Supper> they send techs out to dismantle the equipment now vs letting the demolition crew rip it out
[13:20:00] <L84Supper> archivist, what was the license there for? Just to be sure you were responsible with the equipment vs it ending up in a river or landfill?
[13:20:53] <archivist> it was a waste transport license so yes where you take it was traceable
[13:22:31] <archivist> all waste is supposed to be moved by licensed carrier these days except householder to tip/recycling yard
[14:15:33] <c60> gen3+?
[14:16:14] <archivist> what is gen3+ ?
[14:18:48] <pcw_home> successor to gen2+ ?
[14:25:04] <pcw_home> successor to gen2+ ?
[14:27:54] <_abc_> When is linuxcnc going to leave the Ubuntu sinking boat http://www.theregister.co.uk/2012/09/24/ubuntu_amazon_suggestions/
[14:33:41] <Vq> _abc_: 12.10 isn't released yet.
[14:34:19] <pcw_home> and LinuxCNC will use the LTS version anyway (12.04)
[14:34:37] <_abc_> okay
[14:34:39] <_abc_> thanks
[14:35:28] <Vq> pcw_home: If it's just a practical concern the would-be-ads can be removed with a single command.
[14:37:26] <pcw_home> Yeah didn't seem too bad,
[14:37:28] <pcw_home> just hope Paolo Mantegazza gets some time to finish porting RTAI to 3.2 kernels
[14:39:53] <pcw_home> (2.6.42 in old scheme)
[14:45:32] <pcw_home> There is a adeos ipipe patch for 3.x kernels that was released in July so it should be "in the pipeline" so to speak
[14:48:31] <Legonilsson> Is there anyone in Sweden who has built or rebuilt a machine with LinuxCNC?
[14:50:39] <tjb1> cant show ads if you arent connected to the internet ;)
[14:53:25] <andypugh> Hi Legonilsson: You found the IRC then
[14:56:08] <andypugh> Ah, too late. mrsun, you are in Sweden IIRC?
[14:57:26] <DaViruz_> as am i
[14:57:41] <DaViruz_> but i avoided telling him since i have a feeling he is looking for a private support guy..
[14:59:02] <andypugh> I think he may be: http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=38&id=24555#24555
[14:59:34] <mrsun> i am
[14:59:58] <DaViruz_> andypugh: oh.
[15:00:20] <_abc_> "See the "community" link at the top for IRC details. And be prepared to leave the window open for a few hours while you do other stuff, a lot of the people there only scan new messages every hour or so" <- he missed this part heh
[15:00:51] <_abc_> Some anticommercial types shun even money thrown for free their way eh? ;) <wink>
[15:00:59] <DaViruz_> could be interresting, but not nearly enough time
[15:01:22] <andypugh> I try to avoid taking any money related to my hobbies.
[15:01:51] <_abc_> People would kill to get paid for having fun, man :)
[15:02:55] <DaViruz_> that's where the fun ends
[15:03:32] <andypugh> Just had a new guy sign up from the forum from Westward Ho!, but he seems to have omitted the ! from the name. What is the bettign that the forum software isn't aware that some place names have exclamation marks?
[15:13:33] <_abc_> andypugh: I bet it is removed from some uses, but not from others. Expect password trouble...
[15:13:52] <_abc_> By some uses, I mean, from some instances of data processing in php etc
[15:15:12] <andypugh> Hmm, yes: http://xkcd.com/327/
[15:17:45] <Vq> Legonilsson: It's safe to assume that there are.
[15:18:44] <Legonilsson> Hi andypugh, I had just installed ubuntu and had to restart. One small step for mankind but a giant leap for me!
[15:20:18] <c60> archivist: Gen3+ is a way to keep using Gen3 electronics with new firmwares' Basically I just won't let my makerbot die.
[15:20:30] <c60> or at least so I'm told
[15:21:37] <JT-Shop> I've done private support for money a few times, doesn't hurt my feelings
[15:21:50] <c60> I need to get my hands on one, I just can't convince myself to use a dc extruder anymore.
[15:21:56] <andypugh> Legonilsson: If you need help, the most likely way to get it is to ask here or on the forums. I don't think many folk have the time to commit to commercial support.
[15:22:11] <andypugh> But most questions get answered.
[15:22:31] <JT-Shop> Legonilsson: do you know how to read back what you missed while you were gone?
[15:22:56] <Legonilsson> No I dont
[15:23:03] <andypugh> I was looking at Ultimakers today. They really aren't very expensive, are they>

[15:28:11] <Legonilsson> Thank you, so there is a Mrsun from Sweden
[15:28:36] <Legonilsson> Hi Mr Sun do you speak swedish?
[15:29:07] <Vq> Legonilsson: Where in sweden are you located?
[15:57:29] <DJ9DJ> gn8
[15:59:39] <Legonilsson> Vq: Im loacated 180km south of Stockholm in Valdemarsvik
[16:06:57] <Vq> Legonilsson: I'm from Kalmar and if you were just curious about emc2 usage I can tell you that it exists.
[16:09:49] <Legonilsson> Vq: I have a Lathe, Storebro from -83 in which I'm thinking about to rebuilt with a new control. The machine are in good mechanical shape.
[16:10:25] <Legonilsson> Vq: What kind of machines do you have?
[16:11:13] <Vq> The only emc2 controlled I have is a plasma cutter.

[17:06:09] <KimK> Any updated recommendations on what's the best mini-CPU (ITX?) to get (for building in)? I might want a case and power supply for tabletop development use too, any suggestions there? Is the Intel D525 still the hot item? How about the Gigabyte D525? Other D525s? Any and all suggestions appreciated.
[17:06:47] <andypugh> I think PCW recently found a good one.
[17:07:36] <KimK> Hi Andy, do tell.
[17:07:59] <andypugh> Just looking
[17:08:03] <andypugh> "I got a ASUS E35M1-M for testing with the same on card CPU/APU and its fine (~20 usec latencies) Seems a little faster overall than the D525 at the expense of somewhat higher power consumption (the ASUS E35M1-M has passive cooling and the heastsink gets pretty hot)"
[17:08:26] * KimK is browsing Newegg and Amazon...
[17:09:43] <KimK> Thanks, Andy, I'll look it up.
[17:15:45] <KimK> Should I run with some kind of solid-state-SATA? What does the crowd recommend? Or should I stick to spinning-disk-SATA?
[17:16:27] <andypugh> I like SATA DOM.
[17:17:24] <andypugh> http://www.ebay.com/itm/290726816544 for example.
[17:20:28] <KimK> Thanks again, Andy, that does look very interesting. Have they proved reliable for you, what with power-ups and power-downs, assorted electrical glitches, and whatnot?
[17:21:45] <andypugh> Yes, I have been using one for 18 months on my main LinuxCNC dev machine, compiling several times a day, and I can't think of a harsher test.
[17:23:01] <KimK> Excellent, I'm sold, thanks! Do you notice a speed increase on your compiles? Or did you start with DOM immediately and never tried it with rotary disks?
[17:23:56] <andypugh> I never tried rotary disks in that machine.
[17:25:10] <micges> I have system on ssd and /home on few years old hdd
[17:25:31] <micges> compilations are 2-3x times faster
[17:25:59] <andypugh> I am also using a PicoPSU. You will note that the DOM power cable and a PicoPSU power cable both break-out to a 1980s style floppy power plug. I opted to solder the DOM power cable directly to the PicoPSU terminals.
[17:26:41] <andypugh> Shirley_ you can't be seious?
[18:36:44] <tjb1> anyone want a 20% off harbor freight coupon?
[18:44:28] <KimK> Sorry, had to go away for a bit. Thanks, Andy, thanks, micges (oops, gone).

[20:20:26] <r00t4rd3d> then i dunked it in pizza sauce
[20:20:49] <WillenCMD> you have to rub some robatussen on it
[20:22:29] <tjb1> lacquer thinner
[20:22:52] <r00t4rd3d> "If you cant find the knife just get me a razor blade" - Error #1
[20:24:47] <jdh> razor blade is pretty much never the proper tool.
[20:25:06] <r00t4rd3d> i was just trimming a piece of j-channel
[20:25:13] <r00t4rd3d> i slipped
[20:25:27] <jdh> I knew someone that tried to cut a cable tie with a razor blade. Took multiple stitches and some tendon damage.
[20:26:03] <WillenCMD> i was having an off day that day, and i thought you promised not to tell anyone
[20:27:06] <r00t4rd3d> i made a bandage out of a napkin and black tape and worked the rest of the day
[20:27:33] <jdh> I'm fond of paper towels and duct tape
[20:27:43] <WillenCMD> i wear an 18 gauge solid conductor belt on days when i forget mine
[20:31:53] <r00t4rd3d> me and like 4 guys are going burl hunting tomorrow
[20:32:18] <jdh> hmm... so that's what you call it now.
[20:33:19] <r00t4rd3d> i learned them all on the significance of burl wood
[20:33:21] <r00t4rd3d> wtf
[20:33:27] <r00t4rd3d> i learned them all on the significance of burl wood
[20:34:19] <jdh> gotcha. you and 4 guys, hunting some burly wood.
[20:34:54] <r00t4rd3d> check ebay for the prices of tiny pieces of nice burl and you and 4 guys will go hunting it also
[20:35:40] <r00t4rd3d> pen stock goes for 20-30 bucks for nice pieces
[20:36:25] <jdh> some guys here used to dive for trees in the river, been there forever.
[20:36:28] <r00t4rd3d> 1x1x6
[20:37:00] <jdh> do you have to dry it or something?
[20:37:15] <r00t4rd3d> stabilize it sometimes if its delicate
[20:37:22] <jdh> are they trees, or stuff laying aroudn?
[20:37:35] <r00t4rd3d> if not, i soak it in boiled linseed oil
[20:37:51] <tjb1> what does said wood/tree look like?
[20:38:07] <r00t4rd3d> ever see a round protrusion on a tree?
[20:38:48] <r00t4rd3d> http://homebounddecorblog.com/wp-content/uploads/2011/08/burl1-1.jpg
[20:38:53] <r00t4rd3d> thats a giant
[20:39:18] <r00t4rd3d> http://ketenewplymouth.peoplesnetworknz.info/image_files/0000/0001/8184/Large_burl_on_black_beech.JPG
[20:39:42] <r00t4rd3d> i would cut that fucker down in a heartbeat with a tree hugger crying in the corner
[20:40:19] <r00t4rd3d> the best burls are in the root system just below the ground
[20:42:30] <jdh> anyone made any 1911 grips?
[20:46:03] <r00t4rd3d> see thats something to make with burl wood
[20:46:22] <r00t4rd3d> http://www.customkillergrips.com/afzlburl_45_GRIPS%20003a.JPG
[20:46:47] <r00t4rd3d> people sell those on ebay too for good money
[20:47:34] <r00t4rd3d> very easy to make also
[20:47:41] <tjb1> Have I ever seen an ass on a tree? no...
[20:47:58] <r00t4rd3d> i know you have seen a burl in a tree before
[20:48:14] <tjb1> You just cut the tumor off?
[20:48:18] <r00t4rd3d> most just look like a baseball under the bark
[20:48:35] <r00t4rd3d> yeah, slice it off
[20:48:41] <tjb1> well time to fire up the chain saw
[20:48:48] <tjb1> Ill sell it to you ;)
[20:48:51] <tjb1> fund the plasma table
[20:48:51] <r00t4rd3d> i normally use a hand saw
[20:49:03] <tjb1> I dont have time for a hand saw
[20:49:24] <r00t4rd3d> heh, you dont have the right hand saw then
[20:49:36] <tjb1> No hand saw is faster than a chainsaw
[20:49:40] <tjb1> You crazy.
[20:49:53] <r00t4rd3d> oh yes they are
[20:49:57] <r00t4rd3d> faster even
[20:50:08] <r00t4rd3d> 2 man
[20:50:10] <tjb1> You dont have the right chainsaw then
[20:50:52] <tjb1> :P

[21:06:29] <tjb1> myspace is back eh
[21:13:29] <owhite> hey people I am trying to run a pico systems universal stepper card with the default .ini files, and I'm getting "waiting for s.axes"
[21:14:27] <owhite> http://pastebin.ca/2207414 dmesg
[21:14:29] <owhite> http://pastebin.ca/2207415 linuxcnc_debug.txt
[21:14:31] <owhite> http://pastebin.ca/2207416 linuxcnc_print.txt
[21:14:39] <owhite> relevant debugging files.
[21:14:46] <owhite> any suggestions?
[21:18:21] <jdh> did you try the diagnostic program?
[21:18:39] <owhite> which'n?
[21:18:49] <jdh> http://pico-systems.com/univstep.html
[21:18:57] <owhite> oh. yes. That's working.
[21:19:18] <jdh> right port address ?
[21:20:16] <owhite> yeah so that was something that I found confusing because there isnt one listed in the default. My parport is at 0x0378
[21:25:39] <owhite> users can specify the parport address with the line: "loadrt hal_ppmc port_addr="0x0378""
[21:25:55] <owhite> which seems to work, and if I change the address it then complains.
[21:26:20] <jdh> might try cranking up the debug level?
[21:26:37] <owhite> with dmesg?
[21:26:55] <jdh> in the .ini, change the debug line
[21:27:11] <jdh> (I know nothing of pico )
[21:27:20] <owhite> okay.
[21:28:24] <jdh> is this a livecd version?
[21:28:38] <owhite> I installed from livecd, yes.
[21:29:19] <owhite> ubuntu 10.04.
[21:30:05] <jdh> only thing I saw was teh fault in dmesg
[21:30:29] <owhite> yeah wasnt really helpful.
[21:31:02] <r00t4rd3d> I brushed off the top of this box i made with an apparently dusty brush. Good thing its dry :/
[21:31:04] <r00t4rd3d> http://i.imgur.com/5S7Ii.jpg
[21:31:16] <jdh> might try posting to the forum and see if the pico guy can help.
[21:31:35] <owhite> okay.
[21:31:43] <jdh> nice, did you do that with aspire?
[21:31:48] <r00t4rd3d> yeah
[21:31:58] <jdh> how long for the top?
[21:32:08] <r00t4rd3d> my flash makes the dust stand out mega lol
[21:32:25] <r00t4rd3d> hour and a half roughly
[21:32:29] <r00t4rd3d> at 12ipm
[21:32:34] <tjb1> that the pandora box
[21:32:56] <jdh> pine?
