[00:00:12] <pfred1> yes he took rods and hammered them together
[00:00:37] <pfred1> then bored it out and rifled it
[00:00:45] <Jymmm> bored it how?
[00:00:50] <pfred1> on a lathe
[00:00:54] <Jymmm> rifled it how?
[00:01:08] <Jymmm> how DO you rifle a barrel?
[00:01:33] <pfred1> he had this thing carved out of wood that looked like DNA helix that as you drew the rifling rod throug hthe barrel it would slow twist the cutter
[00:01:39] <Jymmm> I looked once and didn't find much
[00:01:48] <pfred1> today they broach them
[00:01:57] <pfred1> usually the button method
[00:02:11] <pfred1> but this guy used a single cutter
[00:02:13] <t12> broaching machine
[00:02:21] <t12> theres special ones for gun barrels i believe
[00:02:27] <pfred1> he has some way he shimmed it up with a splint of wood
[00:02:41] <pfred1> yeah today they draw what are called buttons through the barrel
[00:02:53] <pfred1> although there are other methods of rifling like chemical etching
[00:03:17] <Jymmm> chem etch a spiral?
[00:03:18] <pfred1> I thnk it is H&K their methods are so precise they can't do ballistic tests on the bullets
[00:03:25] <t12> http://www.youtube.com/watch?v=kvnKSfDUCWY
[00:03:33] <pfred1> because all the bullets that come out of their barrels look alike
[00:04:27] <pfred1> Jymmm we're pretty good at chemical etching today
[00:04:43] <Jymmm> that's one hell of a lathe
[00:05:19] <Jymmm> is it making multiple passes in a single barrel?
[00:05:33] <t12> i believe so
[00:05:37] <pfred1> oh yes many passes the antique way
[00:05:40] <Jymmm> why?
[00:05:48] <Jymmm> demo purposes?
[00:05:48] <t12> prolly get a better cut
[00:05:53] <pfred1> you can only cut away so much metal in a pass
[00:05:58] <t12> also think of the deflection
[00:06:11] <Jymmm> Ok, but the cutter doesn't change diameter
[00:06:17] <pfred1> yeah he shims his cutters up with like splinters
[00:06:24] <Jymmm> oh
[00:06:26] <t12> the cutter is supported on a rod that fits through the barrel
[00:06:33] <t12> for like a .223 thats pretty small
[00:06:48] <pfred1> his rifles were 50 caliber
[00:07:08] <pfred1> you ain't doing no .223 the old way I din't think
[00:07:21] <pfred1> old stuff is often big stuff
[00:07:35] <Jymmm> That's some big cast iron there
[00:07:43] <t12> http://www.youtube.com/watch?v=A7Z9Y-OvDpY
[00:07:46] <pfred1> wrought iron
[00:07:58] <Jymmm> wrought?
[00:08:07] <t12> modern wrought iron aka bent steel
[00:08:11] <pfred1> yes that is what you call hand hammered iron
[00:08:20] <Jymmm> ah
[00:08:27] <pfred1> no such thing as midern wrought today really
[00:08:30] <pfred1> modern
[00:08:31] <Jymmm> I meant the green frame of the lathe
[00:08:51] <t12> some megarich friend of friend
[00:08:59] <t12> had all real wrought iron work done in their richpeople house
[00:09:04] <t12> $150k
[00:09:05] <t12> the blacksmith lost money at it
[00:09:18] <t12> like handrails and whatnot
[00:09:29] <t12> http://www.youtube.com/watch?v=jX0Gj7ZXeGc
[00:09:33] <pfred1> t12 real wrought iron you have to hammer out of a bloom
[00:09:34] <t12> thats the lollest rifler
[00:10:23] <pfred1> but I don't think the nut I saw was even that into it he bought steel rods
[00:33:43] <pfred1> ther is an iron pillar in india thing is like 6,000 years old
[00:34:13] <pfred1> they really made stuff good back in the day!
[00:42:53] <r00t4rd3d> http://www.123dapp.com/catch
[00:54:05] <tjb1> Hello
[01:56:28] <pfred1> why does LinuxCNC hardcode a kernel version inside of itself?
[01:57:50] <Jymmm> pfred1: I don't know, why does LinuxCNC hardcode a kernel version inside of itself?
[01:59:48] <Jymmm> pfred1: are you talking a RT kernel?
[02:04:11] <mrsun> hmm press fit of bushings, will the inside diameter shrink as much as the press fit is ?
[02:04:37] <mrsun> say ive got 0.03mm oversize outside and spot on inside, then press it into a housing then the inside bore will be -0.03mm ? :)
[02:11:23] <Jymmm> mrsun: I think it'll depend on the housing and bushing material
[02:11:45] <Jymmm> you might try and heat the housing material to expand it
[02:23:36] <Loetmichel> *yawn* MORNING! ... there were times when $me was more energetic after getting out of bed... *creaking bones* :-(
[02:33:45] <Jymmm> Loetmichel: you were getting laid back then.
[02:34:21] <Loetmichel> Jymmm: more like: getting old and weary ;-)
[02:35:30] <Jymmm> Loetmichel: Three words... Electric Mattress Pad
[02:40:05] <tripod|> what kind of security tools should be used bevore the inverter?
[02:40:31] <Jymmm> tripod|: ?
[02:42:28] <tripod|> Jymmm i mean those electric parts dont know in english
[02:42:53] <Jymmm> tripod|: Ok, what inverter?
[02:43:01] <tripod|> im looking for a picture
[02:43:11] <tripod|> Jymmm for the motor
[02:43:16] <tripod|> 2kW
[02:43:30] <Jymmm> tripod|: Oh, *I* don't know.
[02:44:03] <Jymmm> tripod|: I thought you were tlaking about a 12VDC to 110VAC inverter, but I wasn't sure.
[02:44:15] <tripod|> you know what i mean?
[02:44:46] <Loetmichel> tripod|: power filter? or did you mean Residual current breaker? ("FI-schalter")
[02:44:51] <tripod|> http://www.elektro-doerr.com/content/image/main/box_right/fehlerstromschutz_03.jpg those parts
[02:44:55] <archivist> tripod|, a filter is probably the word you are looking for
[02:45:02] <tripod|> yes fi i mean^^
[02:45:56] <tripod|> the one which is installed allways switches off, when i start the inverter
[02:46:02] <archivist> good filters may not play well with RCD though
[02:46:10] <Loetmichel> to put an RDC in front of an 3 phase inverter is calling for trouble, unless the RCD has "DC-capability"
[02:46:38] <Loetmichel> ... and the filters have low "ableitstrom"
[02:48:03] <Loetmichel> <- going to work now
[02:48:16] <tripod|> Loetmichel but there are special ones for rdc, but which ones?
[02:48:54] <Loetmichel> tripod|: like i said: "DC-capable" ("Gleichstrom-geeignet")
[02:49:18] <tripod|> sorry auf deutsch gehts einfacher... weisst du gerade, welcher typ das ist?
[02:50:27] <Loetmichel> tripod|: on some Inverters you can disable the input power filters. that may help with the "RDC is switching off" issue. but a not dc capable RCD may still not switch if the inverter is active!
[02:51:00] <Loetmichel> and ow i have to go, already 30 minutes late for work
[02:51:17] <tripod|> have fun @work... i will look for a dc one
[03:11:55] <DJ9DJ> moin
[03:12:09] <Jymmm> DJ9DJ: You're an hour late!!!
[03:12:19] <DJ9DJ> hi Jymmm
[03:12:39] <DJ9DJ> no, i'm not. its my normal time
[03:12:57] <Jymmm> DJ9DJ: Oh, you dont observe daylights savings?
[03:17:59] <DJ9DJ> nope, just clock time ;)
[03:18:11] <DJ9DJ> local time will change last week in march
[03:18:48] <Jymmm> Ah, We just had ours on Sunday
[03:18:53] <DJ9DJ> ah!
[03:41:14] <Jymmm> I'm watching a movie, and the very first time I've ever heard reference to Cordite
[03:53:09] <Jymmm> Mornin Mr Tom
[03:55:50] <Jymmm> Tom_itx: Um, that would be you =)
[06:36:31] <Loetmichel> soooo, cnc place done, wating for the chinese 6040 to arrive.... http://www.cyrom.org/palbum/main.php?g2_itemId=14112
[07:02:09] <jthornton> hmmm
[07:02:12] <skunkworks> what about 'guest books..'
[07:02:23] <jthornton> what is guest books?
[07:03:41] <Loetmichel> ht: i would opt also for a blogging software with guest comments
[07:04:05] <archivist> jthornton, any system that has a proper login and their records "belong" to them
[07:05:06] <jthornton> this is a list of people who have spyders and are willing to help other spyder owners that have problems on the road so search and or sort by state is needed
[07:06:40] <skunkworks> oh - what about some sort of google mapping like what linuxcnc had for a while?
[07:06:50] <jthornton> hmmm I did a database a few years ago but forgot how LOL
[07:07:15] <jthornton> yea, but simpler like a sortable list
[07:08:42] <jthornton> ah ha it was a php sql database I did
[07:08:42] <archivist> you can get the browser to sort tables
[07:09:27] <jthornton> how would you do that?
[07:11:26] <archivist> like on http://en.wikipedia.org/wiki/Comparison_of_project-management_software see little arrows in table header
[07:12:37] <jthornton> yes, I see that
[07:13:15] <archivist> so many ways :)
[07:14:08] * jthornton tries to see how they did that
[07:17:39] <archivist> look at the css <table class="wikitable sortable">
[07:19:47] <jthornton> how do you look at the css file?
[07:20:57] <archivist> when you view source you can see all the files they include pile of .js too
[07:25:19] <archivist> probably not the best example code to look at :)
[07:26:21] <archivist> here is a better example mebe http://www.kryogenix.org/code/browser/sorttable/
[07:27:01] <jthornton> thanks
[07:27:04] <archivist> and he has a nice license
[07:28:18] <archivist> I usually have pre ordained sort order from me database queries
[07:29:44] <jthornton> actually that would work if sorted by state
[07:29:49] <archivist> one thing you may want is by distance from user to user rather than state
[07:30:12] <archivist> and it gets messy then
[07:30:47] <jthornton> this is for helping a rider that has broken down on the road so I assume smart phone to look it up
[07:44:00] <archivist> you want something like http://zcentric.com/2010/03/11/calculate-distance-in-mysql-with-latitude-and-longitude/
[07:44:34] <jthornton> that's cool
[07:44:44] <archivist> how large do you think your data will be
[07:44:59] <archivist> 100 members 1000000000 members
[07:45:01] <jthornton> 300-400 entries maybe
[07:45:23] <archivist> should be ok at that level
[07:46:07] <jthornton> the spreadsheet has 200 but can be hosed up very easy
[07:46:50] <archivist> the problem with that sql is it is run for every row in the table so not that fast
[07:47:51] <archivist> you could add some thing to stop it testing people over 300 miles away
[07:48:31] <jthornton> some people will cruise the list and see who is along their route
[07:49:57] <archivist> like me looking for museums and things up country if on a trip for any other reason
[07:50:12] <jthornton> yep
[08:11:26] <mrsun> Jymmm, hmm sure but when it contracts again it should push the bushing to a smaller size? :)
[08:11:42] <mrsun> have to make bushings for a friends lathe .. and its huge stuff so cant turn them when in place :P
[08:19:02] <sebastian> hi linuxcnc gurus
[08:19:47] <sebastian> i was playing around with kinematics and found a strange behaviour
[08:20:58] <sebastian> when i change KINEMATICS_TYPE of trivkins to KINEMATICS_BOTH, i always get soft limit switch errors after homing and switching to world mode
[08:21:36] <sebastian> does anybody know why?
[08:43:55] <skunkworks_> why do the first 4 videos have nothing to do with linuxcnc?
[08:43:56] <skunkworks_> http://www.youtube.com/results?search_query=linuxcnc&search_type=videos&search_sort=video_date_uploaded
[08:44:42] <skunkworks_> probably 7
[08:45:38] <cradek> keyword spamming, probably
[08:46:14] <cradek> the one with the tooth says "linuxcnc 5 axis cinci at MPMby sws1253"
[08:55:04] <asdfasd> I noticed few years ago youtube search engine suddenly become a crap
[08:56:04] <skunkworks_> it seems to come and go.
[08:56:25] <skunkworks_> The actual page doesn't seem to have any references to linuxcnc. (other than the search info)
[08:56:44] <cradek> yeah
[08:56:53] <cradek> I bet a search for harlem shake works though
[08:56:59] <cradek> get your priorities straight
[08:57:04] <skunkworks_> heh - don't go there
[08:57:15] <asdfasd> try search gangnam style - always shown properly
[08:57:17] <Jymmm> I found this off of one of those playlists, pretty impressive http://www.youtube.com/watch?v=rkhbxOWFJq4
[08:57:20] <archivist> that search did not seem so bad over here
[08:58:27] <skunkworks_> Jymmm, 'fluid'
[08:58:40] <archivist> remember they probably use use your history and location to bias the result
[08:58:43] <Jymmm> skunkworks_: All I can find is that they were posted in the last 48 hours
[08:59:08] <Jymmm> skunkworks_: fluid and serious upper arm strength
[09:14:17] <Loetmichel> hmmm... it may come to mind that the closed driver for the nvidia card isnt the best choice for a linuxCNC machine... jitter of 75k and plus... :-(
[09:14:32] <Loetmichel> back to noveau i think
[09:16:03] <Loetmichel> or has anyione a siuggestion whioch driver to use for a nvidia 8500 GS on a linuxcnc pc?
[09:31:17] <r00t4rd3d> none
[09:32:00] <r00t4rd3d> what ever the stock one that is initially installed
[09:32:57] <Jymmm> alex_joni: New toy for you http://dx.com/p/avoi-avs-tv602-android-4-0-google-tv-player-w-wi-fi-1gb-ram-4gb-rom-keyboard-mouse-black-193707
[09:33:22] <Jymmm> Heh, lets see pfred install lcnc on that =)
[09:33:40] <r00t4rd3d> those mk's are junk
[09:33:59] <Jymmm> mk;s ?
[09:34:07] <r00t4rd3d> mk808 the board you linked too
[09:34:13] <r00t4rd3d> http://www.hardkernel.com/renewal_2011/products/prdt_info.php
[09:34:18] <r00t4rd3d> those are the real dev boards
[09:35:28] <r00t4rd3d> The Odroid-U2 has official CyanogenMod support too
[09:35:42] <r00t4rd3d> http://get.cm/?device=odroidu2
[09:36:11] <Jymmm> You see the heatsink for the one you linked to??!
[09:36:21] <r00t4rd3d> no
[09:36:36] <Jymmm> http://com.odroid.com/sigong/_Files/2012/201211/images/201211251432377371.jpg
[09:36:59] <r00t4rd3d> I was joking.
[09:37:13] <Jymmm> about what?
[09:37:24] <Jymmm> the NK's being junk, or ???
[09:37:50] <r00t4rd3d> the heat sink
[09:37:52] <r00t4rd3d> http://tjakubowski.files.wordpress.com/2013/02/screen1_odroid.jpg
[09:38:02] <r00t4rd3d> the picture just makes it look huge
[09:39:24] <r00t4rd3d> it has a quad core processor and a quad core gpu
[09:41:51] <r00t4rd3d> You can game with it if you choose, decent games
[09:42:24] <r00t4rd3d> something you cant do with those china cheap black MK*** ones
[09:43:58] <Jymmm> I'm not a gamer, so I doubt that'll ever be an issue.
[09:45:08] <r00t4rd3d> the built in wifi sucks too
[09:45:55] <Jymmm> Somehow I'm getting the impression you had one and werent happy with it
[09:47:31] <Tecan> 9 hours to backup 3 tb
[09:47:35] <Tecan> gparted
[09:48:13] <r00t4rd3d> Jymmm, no I just hand around the places where those are discussed.
[09:48:17] <r00t4rd3d> hang*
[09:51:55] <r00t4rd3d> You get what you pay for is the general consensus
[09:52:30] <r00t4rd3d> so many things onboard its all cheap as fuck
[09:56:42] <r00t4rd3d> http://www.ebay.com/itm/New-Black-USB-to-25-Pin-DB25-Parallel-Port-Printer-Adapter-Cable-1-42FFA9FE-/150938418139?hash=item2324a17bdb
[09:57:09] <r00t4rd3d> that would be cool if those worked
[09:57:19] <r00t4rd3d> and someone ported linuxcnc to arm
[09:57:47] <Jymmm> r00t4rd3d: GIT ER DONE! What are you waiting for?
[09:57:55] <Loetmichel> harhar
[09:58:19] <r00t4rd3d> cradek said he was gonna do it
[09:58:43] <r00t4rd3d> :)
[09:58:44] <Jymmm> r00t4rd3d: That was in your wet dreams, nothing in reality, sorry.
[09:58:58] <Loetmichel> r00t4rd3d: usb-> lpt adapter have a grueseome latency. IIRC the usb standard allows a maximum of one second fpr a packet roundtrip. not possible to get a cnc machine running over lpt
[09:59:34] <Jymmm> s/lpt/usb/
[10:00:08] <Loetmichel> over usb->lpt adapter i meant
[10:00:33] <Jymmm> Over USB anything is what I meant =)
[10:01:06] <Jymmm> But, could do a store and forward thing
[10:01:30] <Jymmm> That's how my laser works, just like a printer.
[10:08:03] <jdh> they are usually quoted separately
[10:08:04] <Jymmm> jdh: 30A charging I'd think kill a battery in a couple of days
[10:08:12] <Jymmm> gotcha
[10:08:16] <jdh> but, they are also more often marketing numbers
[10:08:28] <jdh> you can fast charge LiPo (really fast)
[10:08:30] <Jymmm> jdh: derate by ?? %
[10:08:48] <Jymmm> jdh: but kill the life of it
[10:09:10] <jdh> not as much as you would expect (relative to NiMH and SLA)
[10:09:34] <jdh> lots of good videos on LiPo fires from bad chargin
[10:09:38] <Jymmm> jdh: I meant for a battery in general =)
[10:09:53] <jdh> it is chemistry dependent.
[10:10:22] <Jymmm> jdh: and mfg, and quality, and operator, and dumbassness, etc =)
[10:10:54] <jdh> yeah. Some lithium batteries can be pretty hazardous. Home-built packs especially
[10:11:20] <Jymmm> jdh: from single unknown cells
[10:11:25] <jdh> I know a guy that had a Lithium pack for his dive scooter. Tons of power. Burned down his motel room at 2am
[10:12:18] <Jymmm> I thik I'd store a pack in a ammo box at least
[10:12:49] <jdh> main issue is charging, or penetration
[10:12:54] <Jymmm> jdh: was it a custom made bat pack?
[10:13:30] <Jymmm> jdh: did he try charging it too fast/much?
[10:13:31] <jdh> yes, but it didn't have a proper battery management module. 43V? battery, ~30Ah
[10:13:45] <Jymmm> oh fuck
[10:14:59] <Jymmm> If you are putting that much balls into something, you would think you would also have the proper controls too
[10:16:02] <Jymmm> I like my PROTECT 18650's TYVM, then I really dont have to worry about the charger screwing up as much.
[10:18:22] <Jymmm> jdh: But, I'm starting to look at them for my radios, need 13.8@22A MAX draw, so 25C (now that I know what that means =) should do the trick nicely.
[10:18:37] <jdh> 22A seems excessive
[10:18:49] <Jymmm> jdh: 100W RF
[10:19:38] <jdh> I presume you will spend a few seconds transmitting "is anyone else alive" then just rx in despair.
[10:19:42] <Jymmm> Then top that with dgital/CW modes and you can really push it.
[10:20:04] <Jymmm> Well, CW can be longer than "a few seconds"
[10:20:18] <jdh> plug it in to the grid
[10:20:34] <Jymmm> jdh: On tp of a moutian?
[10:20:36] <Jymmm> top
[10:21:17] <Jymmm> jdh: SOTA http://www.sota.org.uk/
[10:21:22] <Err> RF amplifier efficiency isn't traditionally better than 60% or so
[10:23:34] <Jymmm> jdh: On top of that, I'd like to incorporate my 15W solar blanket for charging
[10:34:27] <Jymmm> jdh: When they say 30C (for example), what % do you derate the the "advertised" rating from the realistic one?
[11:34:56] <Loetmichel> Jymmm:model Lipolymer batterys are more or less reliable
[11:35:20] <Loetmichel> the first c-value is usually correct for continous discahrge
[11:36:00] <Loetmichel> the second value for "peak discharge" is sometimes a bit off the scale... derate taht to about double the coninous discharge just to be on the safe side
[11:36:19] <Loetmichel> <- sorts his fingers
[11:40:31] <jdh> insertion sort?
[11:41:12] <archivist> see todays xkcd for the sort he is using
[11:45:11] <jdh> I like the mouseover one
[12:04:59] <R2E4> Hi all.
[12:05:38] <R2E4> How much current I need for the 5 volt power supply for the mesa 5i25/7i77 boards?
[12:06:47] <cradek> I don't know, but the biggest consumers of that are probably your encoders
[12:07:40] <R2E4> Howz it going cradek. thanks, I'll check on the encoders. I am receiving my bridgeport saturday.
[12:07:47] <cradek> slick
[12:08:09] <cradek> can't you just hook it to your pc power supply and not worry?
[12:08:14] <R2E4> He is also throwing in a 1965 colchester student metal lathe.
[12:08:39] <cradek> I always run my encoders on the pc supply so it never loses count from estop, main machine cutoff, etc.
[12:08:45] <archivist> be careful with the throwing its heavy
[12:08:50] <R2E4> cradek, I don't know the power draw, (requirements) so I would rather just get a seperate 5 volt PS.
[12:09:12] <cradek> pc supplies are hugely powerful
[12:09:15] <R2E4> OH..... didn't know that would be a problem.
[12:09:35] * JT-Shop goes to look at what he used in the BP
[12:09:48] <cradek> well if you turn off power to the encoders you'll definitely lose position!
[12:09:51] <R2E4> You are talking a seperate wire from the PC powersupply right? Not using Power pins opn the parallel port?
[12:10:09] <R2E4> right
[12:10:09] <cradek> yes, you can't get any power from a parallel port
[12:10:22] <cradek> use a drive connector or something
[12:10:52] <R2E4> yeah, I have the 7i77 plugged, oh it is a 5i25 card. nevermind....
[12:11:46] <R2E4> pcw_home I remember saying when you connect the drives/encoders you will need to change to exrternal power. I will try the PC power.
[12:12:23] <pcw_home> on a 7I77 you can get 5V power from the FPGA card but if you have a long cable
[12:12:25] <pcw_home> and lots of encoder power it might be marginal
[12:12:55] <pcw_home> (you can always check with a VM on the 7I77 5V connector)
[12:13:24] <JT-Shop> I used a 7009K31 from McMaster Carr
[12:13:42] <JT-Shop> overkill I'm sure at 10w
[12:15:14] <R2E4> I don't know what the bei encoders draw but cradek you've doin it so I should be good.
[12:15:19] <pcw_home> I think the 7I77 5V requirement by itself is about 400 mA (2W)
[12:15:41] <cradek> R2E4: the encoder might say
[12:15:44] <R2E4> Look at this monstor I am constructing......:-) http://www.youtube.com/watch?feature=player_embedded&v=2mTHrDiODYc
[12:16:03] <cradek> R2E4: you don't have light bulbs so it won't be too horrible, but they may be stuffed full of old ttl
[12:16:06] <R2E4> Yeah, I have an image of them somewhere....
[12:17:17] <pcw_home> I dont think those open belts/pulleys are finger approved
[12:17:41] <R2E4> or any other fre swing limbs for that matter.
[12:51:21] <Err> I'm reasonably certain that that free colchester lathe was supposed to be delivered to my house :-)
[12:52:32] <Jymmm> I'm reasonably certain that the delivery option also stated over your cold dead body
[12:53:24] <Jymmm> if not stated, then implied =)
[13:05:16] <L84Supper> http://www.gatech.edu/newsroom/release.html?nid=131491 couldn't they find their own acronym? LAMP is already taken
[13:05:22] <IchGuckLive> hi all B)
[13:07:05] <archivist> L84Supper, so is MARC , book data
[13:11:46] <andypugh> Cool idea, but 3D-printing sand moulds is pretty conventional. In fact I thought that the process described there was already common.
[13:14:44] <IchGuckLive> and 3D printing is getting cheeper and cheeper
[13:15:21] <IchGuckLive> http://www.youtube.com/watch?v=gRZzIhEuEHw

[13:21:49] <IchGuckLive> youo got the licence
[13:22:25] <IchGuckLive> you need to make it private
[13:22:31] <IchGuckLive> not public
[13:22:35] <andypugh> Not available anywhere any more. That's the point. Someone had re-uploaded my video.
[13:22:37] <IchGuckLive> or the other way
[13:23:03] <IchGuckLive> oh that is realy not good
[13:23:20] <IchGuckLive> some foks are realy nasty
[13:23:27] <andypugh> Youtube pulled it in < 24hours, that part is pretty good.
[13:23:42] <IchGuckLive> if seen my plasma tabel also wondering around as freecad modell
[13:24:28] <IchGuckLive> yours or the oher andy
[13:24:42] <IchGuckLive> other O.O
[13:25:29] <andypugh> Mine is still there: http://youtu.be/ZhICrb0Tbn4
[13:25:33] <archivist> andypugh, I wonder how many complained, I did
[13:26:03] <andypugh> It's the second time. I really don't know what they hope to achieve.
[13:27:07] <archivist> time I trawled for my vids to see if any ripoffs are still there
[13:27:38] <IchGuckLive> i dint mind if one craps mine it ia all on opensource
[13:27:51] <IchGuckLive> linuxcnc most
[13:28:03] <IchGuckLive> andypugh: what is the spindel speed
[13:28:19] <Jymmm> Just tag it if you are worried about getting them snag
[13:28:23] <andypugh> I don't know. 500rpm maybe?
[13:29:06] <IchGuckLive> did you get the hal and ini published ?
[13:29:33] <IchGuckLive> woudt be worth for the University to build a mashine only for this showing
[13:29:55] <andypugh> IchGuckLive: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hobbing
[13:30:03] <IchGuckLive> Thanks

[13:32:20] <Jymmm> Pope Jymmm the First, wearing the spiffy cap!
[13:32:35] <pcw_home> We're re-Poped?
[13:32:43] <IchGuckLive> all bels are ringing here in Germany
[13:33:34] <IchGuckLive> andypugh: you cand do that with a parport or 2 or ?
[13:34:03] <IchGuckLive> if i get the second parport input and connect A/B quad endcoders
[13:34:16] <andypugh> You don't need Z-axis control, so yes, a parport will work.
[13:34:59] <IchGuckLive> i think i give it a try this year
[13:36:19] <asdfasd> andypugh: how do you check that somebody copied your video?
[13:36:36] <andypugh> Generally Skunkworks tells me :-)
[13:37:00] <andypugh> How he knows, I have no idea
[13:37:42] <asdfasd> so... ask skunkworks he knows everything hahah
[13:39:28] <archivist> he trawls youtube all day instead of working I think
[13:42:04] <asdfasd> haha
[13:42:49] <IchGuckLive> live fro ROME http://www.zdf.de/ZDFmediathek/hauptnavigation/live#/beitrag/livevideo/1856994/Live:-Schornstein-an-der-Sixtina
[13:49:48] <tjtr33> L84Supper, https://smartech.gatech.edu/bitstream/handle/1853/31740/kambly_kiran_200912_mast.pdf the GaTech printer
[13:51:14] <IchGuckLive> all marching bands coming in
[13:56:14] <L84Supper> tjtr33: they called me last week about printing magnets
[13:56:20] <IchGuckLive> pcw_home: the cable from the plugandplay 5i25 can i use a standard 5m 1:1 cable for this
[13:56:30] <IchGuckLive> subD25
[13:56:44] <andypugh> If it's fully wired it should be fine
[13:56:59] <IchGuckLive> ok
[13:57:27] <tjb1> Killed a driver for my printer :(
[14:00:27] <tjtr33> L84Supper, that sounds tricky, i know edming magnets was tough until we used AC pulses
[14:01:29] <tjtr33> and this seems appropo for todays news, listen for free http://archive.org/details/ACanticleForLiebowitz
[14:03:30] <pcw_home> Umm 5M is questionable and it should be IEEE-1284
[14:04:02] <IchGuckLive> it works on my BOB parport
[14:04:19] <L84Supper> tjtr33: not too hard, it's just having to work with material that is like peanut butter
[14:05:18] <pcw_home> Your parport--> BOB does not have 2.5M Baud serial signals
[14:05:32] <IchGuckLive> agree
[14:06:16] <pcw_home> IEEE-1284 cables have 35 wires
[14:07:25] <andypugh> oops! I was thinking of a 5' cable.
[14:07:46] <pcw_home> each signal has a twisted pair shield GND
[14:08:25] <pcw_home> at 5' probably almost anything would work
[14:08:35] <andypugh> I am reading The Mongoliad. That features a Papal COnclave too, in a spooky way.
[14:09:16] <pcw_home> but the IEEE cables are better because they are shielded
[14:09:37] <IchGuckLive> i will get yoiu a report on this
[14:12:35] <andypugh> I can confirm that a 7i73 works on the end of a 10m cable.
[14:15:50] <IchGuckLive> http://www.retrofit-plus.at/MESA/
[14:18:30] <IchGuckLive> andypugh: what are you using as a I/O for the 7i73
[14:19:05] <andypugh> Currently a matrix keyboard.
[14:19:40] <IchGuckLive> im so happy with the X-boy USB joypad
[14:19:49] <IchGuckLive> BOX
[14:20:15] <pcw_home> the differential signals are good for maybe 50 meters (we tested 30 meters at 10 Mbaud for a week or so with no CRC errors)
[14:22:56] <pcw_home> With 7I76/7I77 daughtercards you have the same serial signal as a single ended
[14:22:58] <pcw_home> TTL level so need to be shorter and cleaner (Hence fussiness about cables)
[14:23:56] <IchGuckLive> ok thanks and BY for today
[14:43:38] <Loetmichel> *great* ... hope the DO deliver tomorrow... have to have 25 Casings for electronics done by next week. -> Geplantes Zustelldatum aktualisiert auf:

[14:44:00] <Loetmichel> ... ups isnt as reliable as it ws...
[14:44:06] <Loetmichel> was
[14:58:19] <Jymmm> Crap, had outbound package stolen off porch last night.
[15:21:47] <tjb1> Jymmm: You live in that bad of a neighborhood?
[15:22:08] <Jymmm> tjb1: No, that's the problem. Crime of convienance
[15:27:09] <tjb1> Took 19 ground wires off an atx...
[15:29:26] <Jymmm> and you'll need to put them back if you draw more than 50mA
[15:32:09] <tjb1> I only need 2 of them for 11amp
[15:41:36] <FinboySlick> L84Supper: Are you involved with these guys too? http://formlabs.com/
[15:46:41] <L84Supper> FinboySlick: nope, they are all MIT propeller heads (and I mean that in the kindest way possible)
[15:47:33] <FinboySlick> On (web) paper, the seem to have hit a sweet spot though.
[15:47:46] <FinboySlick> Price/quality look fairly good.
[15:48:15] <L84Supper> it's slow and only 300um res, we make photopolymers for it though
[15:48:37] <L84Supper> there's another one for less, hold on

[15:50:07] <FinboySlick> L84Supper: Do you (from that we) actually sell a printer too?
[15:50:22] <L84Supper> we make printers in China
[15:51:41] <FinboySlick> But they're straight, right? ;)
[15:51:41] <L84Supper> we might start selling some in the west later this year

[15:53:01] <FinboySlick> L84Supper: Don't hire Chen, he lies on his inspection sheets.
[15:53:24] <L84Supper> i think he's just about done with the design
[15:53:53] <L84Supper> is he inspector #356?
[15:55:01] <FinboySlick> Not sure on his number, I just hold a grudge.
[15:58:36] <L84Supper> Chen is the 5th most common surname in China
[15:58:54] <Jymmm> #4 is Smith
[16:00:53] <L84Supper> ∑ ∑
[16:01:37] <Jymmm> andypugh: Have you tested the latency of that 12V mobo using lcnc?
[16:01:49] <Jymmm> L84Supper: That's # 12
[16:02:05] <Jymmm> ≥≤
[16:02:45] <andypugh> Jymmm: I think so, but can't recall the numbers.
[16:03:02] <Jymmm> andypugh: pass? fail? 24hr+ ?
[16:03:07] <andypugh> They were OK. But rumours are that the video doesn't work _at_all_ with Precise.
[16:03:19] <Jymmm> precise?
[16:03:34] <andypugh> A bit under 10k I think, long-term.
[16:03:40] <andypugh> Precis Pangolin
[16:03:46] <L84Supper> the athlon xp 2400 tested yesterday came in ~100K us
[16:03:50] <Jymmm> andypugh: K, hat is Precise?
[16:03:54] <Jymmm> what
[16:04:02] <L84Supper> Soyo mainboard, forget the chipset
[16:04:33] <andypugh> Jymmm: http://releases.ubuntu.com/precise/
[16:04:36] <L84Supper> worst one ever for latency next to a laptop
[16:04:57] <Jymmm> andypugh: Oh, fucking code names (annoying), could just said 12.04 =)
[16:04:57] <andypugh> L84Supper: I get milions of latency on my Mac VM :-)
[16:06:12] <Jymmm> andypugh: Well, that sucks. Could you try Knoppix Live sometime?
[16:06:34] <L84Supper> I need more coffee, bbl
[16:06:39] <Jymmm> andypugh: I've found that it does a good job at detectning hw
[16:07:29] <Jymmm> andypugh: And leave it to intel to fubar a good thing.
[16:07:29] <andypugh> I haven't tried it myself yet. I don't really care at the moment, it runs headless as a development machine.
[16:08:06] <Jymmm> andypugh: ok
[16:08:13] <Jymmm> gotta go, bbl
[16:15:26] <mrsun> anyone know what that washer on the end of the spindle on south bend lathes are made of ? (the one that sits inside of the gear of the end of the spindle for the gear train) =)
[16:23:13] <Tom_itx> what's it look like?
[16:23:16] <Tom_itx> bronze maybe?
[16:33:55] <mrsun> Tom_itx, nah it feels and looks like some kind of plastic thingie
[16:34:08] <mrsun> dont know if south bend uses the same stuff, this is a swedish manufactured south bend clone
[16:37:25] <mrsun> http://i.ebayimg.com/t/NICE-SOUTH-BEND-9-10K-METAL-LATHE-PART-HEADSTOCK-SPINDLE-TAKE-UP-NUT-WASHER-/00/s/MTA2N1gxNjAw/$(KGrHqN,!oUFDCIENIZwBQ2RiGYwn!~~60_35.JPG
[16:37:29] <mrsun> "take up washer"
[16:38:49] <andypugh> paxolin?
[16:42:02] <mrsun> phenolic is a word i find for it
[16:42:42] <andypugh> paxolin is paper-reinforced phenolic resin.
[16:43:14] <andypugh> It's actually a pretty good material. Lots of useful properties, such as long-term crush resistance.
[16:43:16] <t12> man i sure run out of power on steel quick
[16:44:04] <mrsun> andypugh, ahh, also found "linen/phenloic" .. so dont know then =)
[16:44:28] <andypugh> Some types are fabric reinforced.
[16:45:15] <andypugh> http://www.tufnol.com/tufnol/default.asp
[16:45:45] <andypugh> The "materials" drop-down has paper, fabric and fibre reinforced
[16:46:17] <andypugh> I always prefer "Vole Brand" as voles are cute.
[16:47:40] <andypugh> But ofr your application Carp Brand might be right.
[16:49:00] <andypugh> mrsun: http://se.rs-online.com/web/p/solid-plastic-sheets/0681205/
[16:49:22] <mrsun> ough expensive :P
[16:49:45] <andypugh> You may not need such a big sheet. Try eBay?
[16:50:46] <andypugh> Hmm, actually, I thought KR345 might be rather more than £30
[16:51:29] <mrsun> http://www.ebay.com/itm/PHENOLIC-SHEET-TUFNOL-SUBSTITUTE-200MM-X-100MM-X-2MM-/360500555338?pt=LH_DefaultDomain_3&var=&hash=item53ef81ee4a paper based but dont know what diff it would make realy :P
[16:52:47] <andypugh> Check the specs on the Tufnol site?
[16:53:26] <andypugh> South Bend are US, so they probably didn't use actual Tufnol
[16:53:44] <mrsun> no but like i said, this is a clone made in sweden
[16:53:48] <mrsun> =)
[16:54:41] <mrsun> oh bakelite ... is that tufnol ?
[16:54:50] <mrsun> or phenolic thingie? :)
[16:55:06] <andypugh> Yes, and no. Not reinforced, but otherwise the same
[16:55:17] <andypugh> It's old-school PCB material.
[16:55:23] <andypugh> halrun
[16:55:25] <andypugh> doh
[16:56:03] <mrsun> andypugh, ALOT of stuff was made in bakelite here in sweden in the "olden days" :P
[16:57:20] <fragalot> antique razor scales are often bakelite
[16:57:29] <fragalot> and most of them have started to rot and smell HORRIBLE
[16:57:59] <fragalot> That said I think I may still have a stack of bakelite PCB blanks around, lol
[17:06:28] <mrsun> wellt hanks for the help =) now i know a little more about what to look for =)

[17:49:22] <andypugh> I am really wuite tempted to start smoking a pipe.
[17:58:30] <r00t4rd3d> pack it up!
[18:03:08] <r00t4rd3d> dont hide it, divide it.
[18:33:57] <Jymmm> r00t4rd3d: tobacco pipe
[18:36:24] <andypugh> Actually, I woul dnever need to light it, just carry it to gesture with, and fettle.
[18:37:23] <Tom_itx> anybody use github?
[18:41:54] <Jymmm> andypugh: OSHA would have a field day with the "working conditions" =)
[18:42:20] <andypugh> There are lots of comments about that, but I think they may be misguided.
[18:43:05] <andypugh> Safety is about a lot more than hard hats and hi-viz. Those guys know what they are doing, which is better.
[18:43:11] <ds3> is there a version of the LiveCD with an image for a USB stick?
[18:43:41] <andypugh> ds3: You can just use the stnadard ISO and the Ubuntu "startup disk creator"
[18:43:58] <Jymmm> andypugh: I was taking about the 20T hammer slamming on the 12" thick 2000F steel and slat flying everywhere =)
[18:44:02] <Jymmm> slag
[18:44:14] <andypugh> You think that has changed?
[18:44:29] <Jymmm> andypugh: they didn't even have gloves
[18:44:34] <ds3> andypugh: what do you mean?
[18:44:38] <Jymmm> much less face shields
[18:44:47] <ds3> burn CD then run that on an existing ubuntu system? or?
[18:45:16] <Jymmm> andypugh: Here http://www.youtube.com/watch?v=rLr2G-1WPTI&feature=player_detailpage#t=348s
[18:45:43] <andypugh> ds3: Do you have an existing ubuntu system?
[18:46:02] <ds3> andypugh: sort of... it is CD drives that I lack
[18:46:15] <ds3> mint but I am guessing it si close enough for this discussion
[18:46:46] <andypugh> I am not sure. Ubuntu has an app in the system menu to make bootable media from ISOs.
[18:47:04] <ds3> oh from ISO
[18:47:06] <ds3> gotcah
[18:47:12] <ds3> thought it wanted a real CD
[18:48:08] <ds3> found it
[18:49:02] <pfred1> unetbootin
[18:49:28] <r00t4rd3d> ya
[18:49:43] <pfred1> http://unetbootin.sourceforge.net/
[18:50:10] <r00t4rd3d> check out this cherry blossom bread:
[18:50:12] <r00t4rd3d> http://imgur.com/a/b4X4W
[18:50:29] <pfred1> it does not work for all ISOs though I have had trouble with some looking on the CD drive for install files
[18:51:11] <andypugh> Jymmm: Why would you wear gloves? You are really not meant to touch the hot metal
[18:51:29] <pfred1> gloves just make it burn longer
[18:52:19] <andypugh> Interestinghow thin blacksmiths tended to be
[18:53:02] <Tom_itx> and loggers
[18:53:06] <Tom_itx> and coal miners
[18:53:16] <andypugh> This one is marvellous: http://youtu.be/k_LA_R4ifYk
[18:54:43] <andypugh> Especially later on. How did they make those huge anchors you see rusting away? They just piled small bits of hot metal on with hammers until they had a big piece.
[18:55:16] <pfred1> andypugh you might like this: https://www.youtube.com/watch?v=ozCdCdGOliE
[18:56:04] <pfred1> there are a lot of antique anchors around here
[18:58:10] <jdh> lots of antique anchors and chain around here too... underwater.
[18:58:39] <andypugh> pfred1: I have tried blacksmithing, woodturning, stained glass making and joinery. And all that just on my parents house.
[18:58:55] <andypugh> (like, we made all the door hinges and latches)
[18:59:34] <pfred1> jdh people decorate with the things this is an old ship building area
[18:59:56] <pfred1> andypugh I think I've seen pictures of your parents place
[19:00:11] <jdh> this is an old ship sinking area
[19:00:12] <andypugh> Oh, stone carving too.

[19:00:22] <Valen> Commander Riker's Trying To Sell.....Some Type Of Crap...
[19:01:16] <andypugh> Made the knob on the gable, the kneelers, and the chimney on the left. http://www.bodgesoc.org/Slaithwaite2/Cottage_end.JPG
[19:02:22] <pfred1> Valen this is the best https://www.youtube.com/watch?v=SKqjIv91Zx8
[19:04:20] <Valen> pfred1: thats not "in universe" really
[19:04:38] <Valen> if he was wearing ghostbusters gear it'd be cool
[19:04:53] <pfred1> Valen that would add to it
[19:05:13] <pfred1> as it is I am laughing listening to him
[19:07:25] <pfred1> the comments might even be funnier than Dan though
[19:13:41] <Valen> got a friend with a laser hooked up to emc
[19:13:50] <Valen> any pointers for where to start with raster?
[19:14:37] <andypugh> There is graster (check the Wiki) but I think it looks like a very clever wrong way to do it.
[19:17:18] <andypugh> I made a start at a dedicated raster setup (single purpose motion planner that takes bitmaps as inpit) But didn't get anywhere near finishing it.
[19:17:50] <ds3> rastering lasers?
[19:18:09] <ds3> a few minutes with a perl script or small C program should suffice
[19:18:26] <Valen> the problem isn't creating gcode
[19:18:29] <skunkworks> Valen: there is a guy who took graster and made it better.. let me see if I can find it..
[19:18:41] <andypugh> The problem is in LinuxCNC, synching laser to motion
[19:18:41] <ds3> what's the problem then?
[19:18:45] <Valen> the problem is EMC stops motion when you issue a spindle power command
[19:19:04] <ds3> how are you thinking of doing it?
[19:19:09] <ds3> i got it to work w/o that issue
[19:19:12] <andypugh> Spindle is _not_ the way to control laser
[19:19:20] <andypugh> M66 might be
[19:19:23] <ds3> it is the vector cut that i that issue with
[19:19:31] <ds3> spindle controls worked for me
[19:19:38] <Valen> people are saying M62 P0
[19:20:02] <andypugh> Never trust me to remember G/M codes :-)
[19:20:26] <Valen> M62 P- - turn on digital output synchronized with motion. The P- word specifies the digital output number.
[19:20:34] <ds3> how is everyone else doing the rasterization?
[19:20:51] <Valen> so is the issue with going G1s repeatdly causing stopping still happening?
[19:21:09] <skunkworks> http://www.buildlog.net/forum/viewtopic.php?f=16&t=557&start=110
[19:21:14] <skunkworks> that whole thread
[19:21:15] <Valen> IE as i recall G1 X10 G1 X20 would cause it to slow/stop at X10
[19:21:20] <ds3> G1 X Y S00..... repeatedly?
[19:21:22] <skunkworks> He used a comp to fire the laser
[19:22:00] <PCW> Best way for raster is to clock out the data with the encoder/stepgen count X scale
[19:22:11] <ds3> have people considered this sequence: G00 X Y; S000 M03; Gsomethingfordrilling Pdwell; M05; and repeat?
[19:22:30] <skunkworks> ben has been on the channel
[19:22:42] <ds3> that worked for me
[19:23:37] <pfred1> does LinuxCNC work with the nouveau video driver?
[19:23:54] <Valen> PCW that would be good
[19:23:57] <Valen> any pointers?
[19:24:22] <PCW> Yeah FIFO in and FIFO out
[19:24:41] <andypugh> Valen do you want my config to look at (and finish)?
[19:25:13] <andypugh> Might be a challenge to guess what I intended and what is missing
[19:25:25] <Valen> lol its all above my head probably
[19:25:37] <andypugh> Maybe mine too
[19:25:41] <Valen> how are you doing it?
[19:26:40] <Valen> for reference his machine is a pport stepper
[19:27:13] <Valen> doing it all in G-Code does have some niceties to it
[19:27:28] <andypugh> Two components, userspace Python and realtime C. The idea is that the bitmap is put in shared memory where the C-code can see it. Then the C-code moves the motors and clocks out the intensity.
[19:27:47] <andypugh> I got distracted by trying to make the motion planner finite-jer
[19:27:50] <andypugh> k
[19:28:19] <Valen> sounds messy
[19:28:27] <andypugh> I might finish it one day. But possibly not unless I get a laser.
[19:28:59] <Valen> probably a good end result but it feels less good than doing it all in pure G-Code
[19:29:06] <andypugh> Well, there is no G-code, and a very simple UI that just lets you open a bitmap and say where you want the raster corners
[19:29:08] <Valen> you could raster and vector then
[19:29:24] <Valen> my C is also terrible ;->
[19:29:57] <Jymmm> +++++----+++-
[19:30:05] <PCW> finite jerk is rather gilding the lilly since you may just overscan so the ramp-up and ramp-down are all done outside the 'painted' area
[19:30:34] <andypugh> Yeah, but I do what interests me at the time. This is a hobby :-)
[19:31:11] <PCW> might be good for 3D object painting
[19:31:40] <andypugh> Yes, galvanometers and photopolymer.
[19:33:17] <PCW> For 2D raster (printers etc), overscan probably makes sense
[19:39:28] <MrTrick> Has anyone here built a machine with rotational axes? I've got a scara arm with planetary geared steppers, and I'm having issues with backlash.
[19:40:00] <andypugh> That's more of a hardware issue
[19:40:28] <MrTrick> I've attached a lawnmower pull-start spring to one joint, and that sort-of works. (eg some preload to keep it at one end of the travel)
[19:40:45] <MrTrick> andypugh: I understand. I didn't think there was a more general cnc channel.
[19:41:17] <andypugh> Is this a new SCARA or an old, worn one?
[19:42:47] <MrTrick> new, but custom built.
[19:42:55] <MrTrick> It's using these steppers; http://www.phidgets.com/products.php?category=23&product_id=3318_1
[19:46:38] <Valen> MrTrick: hypocycloid gears can be pretty low backlash and cut on a DIY mill
[19:47:17] <MrTrick> andypugh: no, they're just servos. I had some success with writing some backlash compensation code, but it was a pretty ugly hack. ^_^
[19:47:22] <Valen> otherwise you can look for, garh whats the fancy ones
[19:47:34] <MrTrick> The mower spring seems to work okay, but I'd rather it had more torque.
[19:47:52] <MrTrick> and harmonic gearheads (is that what you meant Valen?) are hard to find.
[19:48:00] <Valen> thats the one
[19:48:33] <MrTrick> The "if I had to do it again" file contains those. It also contains "Run away. Run!"
[19:48:37] <andypugh> MrTrick: Have you tried the backlash compensation built-in to LinuxCNC?
[19:48:57] <L84Supper> support for laser control for SLA is in the works
[19:49:29] <L84Supper> laser modulation as well
[19:49:32] <Valen> take a look at hypocycloid gearboxes MrTrick
[19:49:39] <MrTrick> I'm actually generating gcode on the fly, in windows, so linuxCNC had a few hurdles. I'm actually using the grbl stepper control firmware at the moment.
[19:49:46] <Valen> L84Supper: for sla?
[19:49:53] <L84Supper> Valen: yes
[19:49:55] <MrTrick> Valen: Any idea where I could get some? Before Monday?
[19:50:06] <MrTrick> For NEMA17 motors? :-)
[19:50:11] <Valen> L84Supper: as in what does "for sla" mean?
[19:50:29] <L84Supper> Valen: 3d printing
[19:50:58] <L84Supper> if you only need to print one layer then it could also be used for laser engraving
[19:51:10] <L84Supper> the code that is
[19:51:52] <L84Supper> i guess you could also laser engrave with multiple passes
[19:52:42] <L84Supper> interlace the laser scan for materials that might melt if you just blasted the same area for too long
[19:53:06] <L84Supper> melt or burn/fire
[19:53:06] <mozmck> MrTrick: how do you like grbl, and have you looked at smoothieware?
[19:54:45] <Valen> MrTrick: you the guy asking on the hackspace list about winding springs?
[19:54:48] <MrTrick> mozmck: So far, it seems great. There are a few things that would be nicer like software limits, but I understand they're working on it. Some of the configuration is compile-time, but again there's development effort towards moving it all to runtime.
[19:54:54] <MrTrick> Valen: ^_^ Yes.
[19:55:06] <Valen> also to get around your backlash, occy strap from a handy wall
[19:55:07] <MrTrick> haven't seen smoothieware yet.
[19:55:21] <andypugh> Making springs is pretty easy
[19:55:35] <Valen> if you want to make the spring stronger you could shorten it
[19:56:27] <andypugh> You just need the right material (cold-drawn carbon steel, also known as Piano Wire) and a mandrel to wind it round.
[19:56:30] <MrTrick> I did try using rubber as a tensioner. It needs to wrap around the joint somewhat, to support the necessary movement. The problem is that while it works very well while tightening, when loosening it tends to 'stick' somewhat.
[19:56:50] <Valen> nah, you are missing the idea, strap from the "head" to a wall
[19:57:09] <MrTrick> Valen: works fine for the shoulder joint. Not so well for the elbow joint.
[19:57:22] <Valen> use 2?
[19:57:26] <L84Supper> laser control should also include analog modulation and also pulse width
[19:58:16] <andypugh> Sad to say, with a SCARA, if you have mechanical backlash you are probably in trouble.
[19:58:19] <MrTrick> I wound a spring from piano wire - sort of worked. I need to 3d print a holder to keep it aligned though (like a very narrow very deep spool)
[19:59:06] <MrTrick> andypugh: Oh I know. :-\ The saving grace is possibly that sufficiently strong springs should fix it - the load on the end effector is very low.
[19:59:11] <andypugh> Shouldn't be necessary with the right shape of spring.
[19:59:31] <andypugh> Think clothes-peg style spring
[20:01:05] <andypugh> http://www.opentech.org.uk/2013/cfp/
[20:01:28] <MrTrick> I have tried one of those.http://imgur.com/58rzm3E
[20:02:00] <MrTrick> I needed to redesign the elbow joint unfortunately, and I now need a flat spring.
[20:02:03] <andypugh> MrTrick: Possibly too many turns
[20:02:33] <mozmck> MrTrick: smoothieware.org the motion control is based off of grbl, but the thing runs on an LPC1769 which is a 100mhz 32-bit ARM cortex-M3
[20:03:10] <MrTrick> mozmck: ah, that one. Looked at it briefly, but it's way overkill. I only need two axes. (the end effector is servo controlled through a micro maestro)
[20:03:48] <tjb1> http://jalopnik.com/ten-traffic-laws-that-need-to-change-453513991 - Motorcycle lane splitting is a no brainer huh?
[20:04:26] <MrTrick> andypugh: quite possibly. It was cut and bent from a much longer tension spring. Still, it tends to want to deform, so keeping a smooth tension is difficult.
[20:05:02] <andypugh> Yes, you need space between the coils for a torsion spring.
[20:06:34] <andypugh> tjb1: Not sure. I see folk lane-splitting at ludicrous speeds. Like through 70mph traffic at 90.
[20:06:49] <Jymmm> Lane splitting is LEGAL in Calif
[20:07:33] <andypugh> ("Filtering" as we call it is neither illegal nor legal in the UK)
[20:08:04] <andypugh> Oh, and for context, I have never owned a car. 100% motorcyclist.
[20:08:31] <Jymmm> never?
[20:08:46] <Jymmm> Last I checked Fod dont make bikes =)
[20:08:50] <Jymmm> Ford
[20:09:00] <Valen> they are trialing filtering at stopped traffic here
[20:09:22] <andypugh> Yeah, I only work for Ford, I don't buy them :-)
[20:09:31] * Valen owns a ford
[20:09:42] * Valen guarantees andypugh didn't make any part of his ;->
[20:10:17] <andypugh> In truth, I once had a half-share of a Dodge Aspen when working in the UK as a student (Working as a cook on a girls summer camp. SOunds like the plot of a tawdry film)
[20:10:35] <Valen> a good tawdry film
[20:10:39] <andypugh> Err, US.
[20:12:21] <Valen> http://www.vapourforge.com/jake/general/hotness_touched.jpg my ford ;->
[20:13:01] <andypugh> No, I am fairly sure I had no part in the creation of that hideous machine :-)
[20:13:51] <Valen> you take that back heathen
[20:14:00] <Valen> the hotness is awesome ;->
[20:14:12] <Valen> inline 4 liter 6
[20:16:07] <andypugh> ROFL! Me at work. (I have Pooh bear on my desk now) http://www.caradvice.com.au/wp-content/uploads/2009/09/2010_Ford_C-Max_01-625x416.jpg
[20:17:04] <tjb1> andypugh: Lane splitting is stupid
[20:17:13] <tjb1> I wouldn't trust the people in the cars or the person on the bike
[20:17:38] <Valen> they succeded in making it look ugly at least ;->
[20:17:46] <tjb1> People around here don't even use turn signals and they pull out in front of you
[20:17:47] <Valen> what is your dayjob andypugh?
[20:18:05] <Valen> somebody did that to my missus whilst she was on her motorbike
[20:18:12] <Valen> and on the phone at the same time
[20:18:28] <Valen> missus punched the driver in the face as they were merging in then sped off
[20:18:42] <tjb1> Hahaha
[20:18:56] <tjb1> Pretty brave to drive that close to punch someone though
[20:18:59] <Valen> sounds like she broke the drivers nose, apparently blood sprayed all over the screaming passenger (who had seen my missus)
[20:19:16] <Valen> the car was merging into her lane, into the exact spot she was in
[20:19:33] <Valen> I view motorcycles as organ factories
[20:19:44] <andypugh> Valen: I am a development engineer. I tell gurls I am a test driver, but that's only partly true.
[20:19:46] <Valen> IE when i need a new liver it'll probably come from a motorcyclist
[20:20:04] <Valen> i bet you have the more interesting job 95% of the time andypugh ;->
[20:20:07] <tjb1> I sold my motorcycle after I almost wrecked it in a turn
[20:20:30] <Valen> she is very sensible, she doesn't lane filter, won't sit in anybodies blind spot etc
[20:20:36] <Valen> she drives it like it was a car
[20:20:45] <andypugh> You have to be really dumb to crash a bike in a straight line
[20:21:07] <Valen> andypugh: or get run over by a truck who is changing lanes
[20:21:24] <L84Supper> motorcycles are nearly invisible to most drivers here, I used to get hit in my Alfa with the top down, drivers would say they didn't even see me
[20:21:25] <tjb1> I'd never take a motorcycle on a freeway
[20:21:26] <andypugh> There is _generally_ room for everyone.
[20:21:32] <tjb1> That draft coming off trucks is scaaary
[20:21:38] <Valen> there are a few trucks with little pointy girl fist sized dents in their doors
[20:21:49] <andypugh> It's no problem at all if you go fast enough.
[20:22:13] <tjb1> Saying you didn't see them is just an excuse
[20:22:29] <Valen> hah, 16km/hr over the limit here is ~$500 fine
[20:22:42] <Valen> 40km over is instant loss of licence and potential jail time
[20:22:49] <andypugh> (seriously, this is not macho posturing, it's physics. To cope with side winds you need to be able to generate high lateral forces, and on a bike that needs enough speed)
[20:23:15] <Valen> a 90kg rider will also help ;->
[20:23:48] <andypugh> Your lass sounds like fun :-)
[20:23:57] <Valen> she is pretty good ;->
[20:24:07] <Valen> and she really likes the new tyres we got her
[20:24:23] <Valen> used to have arrowtrax, now got bridgestone bt-45s
[20:24:31] <Valen> she has an old 250cc
[20:24:35] <Valen> the new ones are soooo crap!
[20:24:52] <L84Supper> Valen: what model is that Ford?
[20:24:57] <andypugh> Anyway. I only have a bike, I do 12k miles a year, and I haven't crashed for 10 years. (discounting a moment of over-exuberance on a racetrack)
[20:24:58] <Valen> hers is like 45+HP the new 250s are 1 cylinder of 10Hp crap
[20:25:02] <Valen> Au falcon
[20:25:16] <Valen> its australian (but thats not where the au is from)
[20:25:34] <Valen> on a race track isn't counted, your sposed to crash there
[20:25:51] <L84Supper> I haven't seen it here or in Asia
[20:26:07] <Valen> nope, australia, NZ and aparantly south africa
[20:26:22] <andypugh> Arrowmax(?) are pretty darned old. BT45s are pretty good, but I rather rate Michelin Pilot Power (might not have a 250cc fitment).
[20:26:45] <Valen> we got those ones because they are dual compound and she is mainly on the motorway
[20:27:10] <andypugh> You should buy her an R6. :-)
[20:27:20] <andypugh> Or maybe an R1, why mess about?
[20:27:35] <Valen> she really likes the 250cc
[20:27:43] <Valen> and dislikes pointy fronts
[20:28:02] <Valen> http://www.moto-data.com/moto/Yamaha-Zeal-250.jpg is what she has
[20:28:25] <Valen> it only weighs like 120kg or so
[20:28:27] <andypugh> Hmm, OK. The problem with 250s is that, in general, the parts that matter are a bit budget.
[20:28:40] <Valen> 20 odd years old, goes like stink
[20:28:51] <Valen> the new 250's are shitefull
[20:29:01] <Valen> the only thing I'm looking at doing is fuel injection
[20:29:08] <andypugh> Yeah, the engine is the least important part.
[20:29:26] <Valen> rebuilt the front shocks and everything
[20:29:33] <Valen> polished all the aluminum up too ;->
[20:29:53] <Valen> going to get a respay soon, in metallic green with butterflies, possibly an airbrush job
[20:30:04] <andypugh> My R1 chassis and suspension won't let me crash. It's all so solid and competent that as long as the tyres are on the tarmac, it can be recovered.
[20:30:33] <Valen> she is pretty good at not getting into situations that need recovering from
[20:30:48] <Valen> i think she got her wild motorcyling out a while ago on the farm when she was growing up
[20:31:04] <Valen> now its a (fun) form of A-B transport
[20:31:17] <Valen> she was banned from a motorcross track once
[20:31:30] <andypugh> That Zeal really does have very spindly forks by current standards, and that feeds an unpleasant Normal Mode
[20:31:51] <Valen> she was beating all the boys (she was like 15) so they crowded her off the track into the fence
[20:31:58] <andypugh> (Err, Normal Mode is a vibration science term)
[20:32:41] <Valen> she jumped off the embankment and rode around the corner on the wire mesh (ball of death style) that "protects" the spectators, overtook the boys then rode it back onto the ground after the corner
[20:32:49] <Valen> they said she won the race but don't come back
[20:33:07] <andypugh> "they" need to get over themselves.
[20:33:09] <Valen> she also ran her self over with a quad bike
[20:33:24] <andypugh> I think that's quite common
[20:33:51] <Valen> I've seen a few motorcross events, never seen that ;->
[20:34:10] <andypugh> That Zeal engine would make a nice 500c V8
[20:34:20] <tjb1> I had a honda shadow sport I think, one turn I almost ran it onto the berm on a turn
[20:34:23] <tjb1> sold it after that
[20:34:43] <Valen> I want to turn my falcon engine into a V12 ;->
[20:34:47] <Valen> they are brilliant engines
[20:34:57] <Valen> go for 1 million Km in taxies without a rebuild
[20:35:02] <andypugh> Yes, well, The Shadows can't actually do corners, the "Sport" part is there to confuse you
[20:35:04] <L84Supper> machine vision and laser control are the two things we are working on, the vision system may be used to align the machine to fiducials or the edges of parts
[20:35:18] <tjb1> I dont remember what it was but it was only like a 600
[20:35:22] <L84Supper> both should be done by the summer
[20:35:42] <tjb1> If I would have hit the berm I would have been slamming into trees at 50 mph
[20:35:42] <Valen> I'm going to need to richen up her mixture, friend rebuilt the carbs and the power band is at 8k plus, which is fine for racing, but she rides it up to 8krpm
[20:36:16] <Valen> i figure running it a bit rich should increase the torque and drop the power band somewhat
[20:36:18] <andypugh> tjb1: The trick is to lean far enough.
[20:36:29] <tjb1> I know
[20:36:30] <tjb1> :)
[20:37:08] <Valen> missus is also short, so many of the 600's the seat is too tall for her
[20:37:32] <andypugh> Valen: Maybe. Maybe an air leak if it isn't meant to be like that, and I would check the carb diaphragms on any 20 year old bike.
[20:37:42] <Valen> they are aparently ok
[20:37:58] <Valen> its a difference since the rebuild
[20:38:13] <Valen> it also doesn't start when "cold" as well as it used to
[20:38:26] <Valen> it wants choke whereas before it only needed it on cold days
[20:38:42] <andypugh> Buy her this: http://www.bikeexif.com/custom-indian-motorcycle
[20:39:03] <Valen> She is somewhat keen on the idea of a falcon engine (I6) bike
[20:39:11] <Valen> it'd be a "cruiser" ;->
[20:39:37] <Valen> only 220Kw or so, but 450Nm of torque or so at 2000 RPM
[20:40:32] <andypugh> Just find her a Benelli Sei?
[20:40:43] <Valen> andypugh: hah, she would be dead in 5 minutes on the motorway as everybody runs her over without seeing her
[20:41:00] <andypugh> Eh?
[20:41:14] <Valen> on the indian
[20:41:43] <andypugh> If she was doing 200mph they coiuldn't?
[20:42:13] <andypugh> I doubt that Indian is slow.
[20:42:47] <andypugh> Even the Americans can't make an 1800cc engine make less than 100hp
[20:43:33] <Valen> lol
[20:48:42] <andypugh> But the Sei sounds like the ideal bike. Stupid, exotic and old. Like the Zeal :-)
[20:49:59] <Jymmm> 2.1HP, 32K RPM spindle motor http://dx.com/p/hsp-vx18-nitro-methanol-engine-for-1-10-r-c-car-truck-blue-black-silver-193391
[20:50:17] <Valen> kinda loud though
[20:50:39] <andypugh> Needs a shopvac for cooling too
[20:51:27] <Valen> probably more than that
[20:53:19] <Jymmm> ok, spindle and cooling pump motor, how's that?
[20:55:48] <pfred1> andypugh a guy I knew his uncle holds the worlds record for HP per cubic inch
[20:56:12] <andypugh> That's a record I would love to hold :-)
[20:58:39] <pfred1> google jim feuling engineering quad 4 turbo
[20:59:23] <pfred1> he's dead now but I think his record still stands
[21:00:52] <pfred1> something like 2,500 HP out of 184 cuin ?
[21:02:02] <andypugh> Talk about nominative determinism.
[21:04:07] <L84Supper> what type of fuel?
[21:04:58] <pfred1> I don't know
[21:05:08] <pfred1> car ran 221.663 MPH though
[21:05:26] <pfred1> not bad for a 4 banger
[21:07:07] <L84Supper> super fuel gets 8500-10K HP out of a 426 cu in
[21:07:14] <pfred1> Larry told me when he went to visit his uncle he had sheds in his backyard where he would run engines
[21:07:23] <L84Supper> http://en.wikipedia.org/wiki/Top_Fuel
[21:07:27] <pfred1> run them til they blew up
[21:08:06] <pfred1> hemis are awesome motors out of the factory
[21:08:17] <uw> L84Supper, 500ci
[21:08:41] <pfred1> the best drag is a 426 vs a 440
[21:09:39] <L84Supper> and about as reliable as a Jeep :)
[21:09:55] <pfred1> the 440 will be halfway down the track and the hemi will just be coming off the line then all of a sudden it is like the 440 just stopped and the hemi shoots right by it
[21:10:03] <Tom_itx> cuda 440 6 pak
[21:10:27] <Tom_itx> that was a fun one
[21:10:50] <pfred1> 440s are truck motors
[21:11:11] <Tom_itx> was it a 383?
[21:11:14] <Tom_itx> i forget
[21:11:15] <pfred1> I knew a guy who had a 426 superbird
[21:11:18] <Tom_itx> i bet it may have been
[21:11:22] <pfred1> the 340 was nice
[21:11:37] <Jymmm> Heh, I had a 76 Buick Rivera with a 455 , Full to empty in 3.4 miles!
[21:11:43] <pfred1> 340 cuds were something to be reconed with
[21:11:51] <pfred1> cudas even
[21:12:52] <Tom_itx> yes it was a 440
[21:13:20] <pfred1> people liked them because it was a big number and they were fast but back then there was plenty faster
[21:13:24] <Tom_itx> http://www.youtube.com/watch?v=9XuyxcMIykY
[21:13:45] <Tom_itx> similar
[21:14:45] <L84Supper> Jymmm: I had a 66 Chevy pickup with a 454 that had about the same mileage :)
[21:15:07] <pfred1> 3 pounds of dirt makes my Chevy heavy
[21:15:17] <Jymmm> L84Supper: When I raced it, you could watch the fuel gauge move =)
[21:15:55] <Tom_itx> my friend kept a funny car in his garage
[21:16:03] <Tom_itx> keith black 540
[21:16:40] <jdh> my wife keeps her car in the garage, it's quite annoying
[21:17:02] <Jymmm> jdh: does she ever drive it?
[21:17:20] <Tom_itx> on sunday
[21:17:50] <Jymmm> well, that's the day you start "cleaning" the garage =)
[21:18:02] <Jymmm> what YEAR you finish is up to you =)
[21:18:38] <Jymmm> jdh: I think you need to move the tanks from the man door to in front of the car door =)
[21:20:13] <L84Supper> http://imagebin.org/250178
[21:20:26] <pfred1> how do you install the kernel source in LinuxCNC? I tried aptitude install linux-source-2.6.32 and all that pulled was a few documents
[21:20:27] <Jymmm> nice truck!
[21:20:31] <L84Supper> fun truck
[21:20:47] <Jymmm> L84Supper: yours?
[21:20:59] <andypugh> Tom_itx: It's a big engine, and claims 390hp. But it isn't actually very fast is it?
[21:21:02] <L84Supper> was, sold it a few years ago
[21:21:09] <Jymmm> L84Supper: WHY?!
[21:21:26] <Jymmm> L84Supper: and how much?
[21:21:55] <L84Supper> now I drive land tanks
[21:22:15] <L84Supper> slightly better mileage but they never break
[21:22:26] <Jymmm> L84Supper: and how much?
[21:23:01] <andypugh> I have never figured out how a 400hp US car can be so much more languid than, for example, a 400hp Ferrari.
[21:23:11] <L84Supper> http://imagebin.org/250179 heh, don't remind me
[21:23:39] <pfred1> andypugh I donno there sport we got cars you couldn't touch the dashboard in if your life depended on it
[21:23:41] <Jymmm> L84Supper: behind seat fuel tank?
[21:23:50] <Jymmm> L84Supper: Really, how much?
[21:24:01] <L84Supper> Jymmm: yes, right where you can see it :)
[21:24:07] <Jymmm> =)
[21:24:26] <pfred1> andypugh that was something a guy I knew did he'd put a $100 bill on the dash and say if you can grab it it's yours then he'd punch the gas
[21:24:37] <Jymmm> L84Supper: how much did you sell if for and have engine pics?
[21:25:31] <andypugh> pfred1: Factory built car?
[21:25:42] <pfred1> andypugh yes
[21:26:31] <andypugh> OK. But in that video that Cuda makes a lot of noise, and looks great, but the lamp-posts are hardly flashing past
[21:27:10] <pfred1> when I was in high school one kid owned a 71 cuda and he lost control on this one stretch of highway man it was legendary
[21:27:39] <pfred1> he did like 2 360s through this S turn and didn't hit anything
[21:28:20] <andypugh> That could be huge power, it could be a bad driver and 1970s tyres
[21:28:37] <Jymmm> I did a 540 once, ended up the front tires were BOTH touching the curb =)
[21:28:37] <pfred1> oh it was total dumb luck
[21:29:03] <pfred1> I mean if you knew the guy he wasn't the type I don't even know why he had the car
[21:29:08] <Jymmm> You just gotta love hand brakes =)
[21:29:25] <pfred1> the best is doing Js
[21:29:36] <pfred1> when you ram a car in reverse while you're driving
[21:29:48] <pfred1> and do a J burnout
[21:30:12] <pfred1> not every car can do it
[21:30:30] <Jymmm> Nah, I was always afraid I'd drop the tranny if I ever tried =)
[21:30:35] <pfred1> a 64 Belair can though
[21:30:58] <pfred1> well he did own his own tow truck the kid that did those
[21:31:25] <L84Supper> heh, I did that once in heavy traffic, 180's back and forth 3-4 times, ended up with two wheels up on the curb but didn't hit a thing
[21:31:26] <pfred1> so if the trans dropped out he could pick the whole mess up
[21:31:39] <Jymmm> LOL, so does a friend, we got my car stuck, then got his tow truck stuck =)
[21:31:52] <L84Supper> in 1968 GTO conv
[21:32:20] <pfred1> poor Bret
[21:32:30] <pfred1> he has an old goat but hs is blind now
[21:32:48] <pfred1> last time someone went to visit him he asked to be taken for a ride in it
[21:33:09] <Jymmm> the blind goat?
[21:33:10] <L84Supper> my biggest lesson at ~18, always have the air filter on when running the engine
[21:34:50] <L84Supper> had just spent several days rebuilding a chevy smallblock, figured lets take it around the block after getting it started, half way around it backfired, engine fire, large melted paint spot on hood (including anything plastic) and cracked windshield :)
[21:40:07] <pfred1> I knew this one idiot he had a Fiat and he was messing around with it and it backfired through the carb I swear the flame that shot out was like 20 feet high
[21:40:34] <pfred1> the Fleat
[21:41:11] <pfred1> he always said that car had an Experimental Alpha Romeo engine in it and I thought yeah a failed experiment

[21:52:07] <L84Supper> anyone ever use newport?
[21:52:31] <pfred1> I've smoked a couple
[21:57:28] <tjtr33> which Xilink Webpack do you use? 14.4 wont add any IP , all are greyed out for all devices.
[21:57:42] <tjtr33> Xilinx says to do full install & hack. I'm leary of more bugs
[22:01:16] <MrTrick> L84Supper: That looks nifty, and expensive! I've used little Newport linear steppers before, they had about 10um repeatability.
[22:02:28] <L84Supper> http://search.newport.com/?q=*&x2=sku&q2=IMS400PP website says 1.25um for this series
[22:03:19] <L84Supper> $5812.00 Availability: In Stock for new
[22:08:56] <tjtr33> L84Supper, these guys have been around a while and are kinda local, maybe able to help http://www.milwaukeemachinetool.com/
[22:10:25] <L84Supper> tjtr33: just shopping for bargains
[22:11:08] <L84Supper> Hiwin stocks their ball screw driver linear units in Elgin
[22:11:16] <L84Supper> few day delivery
[22:12:10] <tjtr33> yah, big warehouse, TW mfctr, consider STAR from DE too
[22:13:04] <pfred1> is there any way to get the kernel source for LinuxCNC today?
[22:17:17] <tjtr33> L84Supper, newport is so expensive, look at good ol schneeberger too http://www.schneeberger.com/products/precision-positioning-systems-motion-systems/
[22:17:41] <pcw_home> prfed1: Hows your 2.6.38 running?
[22:18:58] <pfred1> pcw_home I had rtai running but when I went to start X Window it wouldn't then when I got X Window running the RTAI environment got lost
[22:19:22] <L84Supper> tjtr33: Parker is 3-4 lead time, nut you can expedite for a fee, the problem is if they run late you just get the extra fee back
[22:19:34] <pfred1> so I've done some research and thought maybe the kernel from LinuxCNC might be better but so far I cannot figure out how to get it
[22:19:35] <pcw_home> Thats a head scratcher...
[22:20:11] <pfred1> see the Ubuntu 10.04 kernel was patched to run the nouveau video driver
[22:20:30] <Valen> any paticular reason for using nouveau?
[22:20:39] <pfred1> but if nouveau is in 2.6.38 damned if I can find it
[22:20:53] <pfred1> Valen the nv driver is pretty sucky
[22:21:01] <Valen> works ok for me
[22:21:05] <Valen> or at least it did
[22:21:08] <pfred1> don't mean it ain't sucky
[22:21:10] <Valen> dual cpu host though
[22:21:27] <Valen> using nvidia driver
[22:21:31] <pfred1> for real nVidia cripples it on purpose
[22:21:52] <pfred1> their stated policy is run our binary driver
[22:21:53] <Valen> I was getting 4000 latency with that machine
[22:22:17] <pcw_home> I thought the nouveau driver had latency problems
[22:22:23] <pfred1> it might
[22:22:50] <pfred1> I haven't been able to check it out other than on the LinuxCNC CD
[22:23:47] <pfred1> I try to install the kernel sources with the CD and I get nothing
[22:24:05] <pfred1> if there is some trick to it I'm not figuring it out
[22:24:18] <pcw_home> You just want to try the binary ubuntu 10.04 kernel?
[22:24:33] <pfred1> no I want to pull the source and build it
[22:25:04] <pfred1> but nothing downloads a couple text files and that is it
[22:25:09] <pcw_home> you are a glutton for punishment
[22:25:41] <pfred1> dpkg -L linux-source is like 2 text files
[22:26:13] <pcw_home> probably only the linuxcnc config info
[22:26:16] <pfred1> yeah the whole LinuxCNC thing is like a rock and a hard place
[22:26:32] <pfred1> /usr/share/doc/linux-source/copyright & /usr/share/doc/linux-source/changelog.gz
[22:26:36] <pcw_home> try xenomai?
[22:28:06] <pfred1> I don't know what it is
[22:28:42] <pfred1> technically if the kernel source can't be produced the program cannot be distributed
[22:28:42] <pcw_home> You probably need to ask build questions on the devel list when there is someone there
[22:29:01] <pfred1> I mean the Linux kernel is GPL
[22:29:03] <pcw_home> you need to get it from Ubuntu
[22:29:20] <pfred1> well I don't think they're distributing it anymore
[22:29:35] <pfred1> I got a 404 when I tried to get it
[22:29:45] <pfred1> file not found
[22:29:58] <pfred1> maybe I need to modify my sources.list ?
[22:30:17] <pcw_home> linuxcnc on xenomai:
[22:30:20] <pcw_home> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?XenomaiRuntimePackage
[22:30:54] <pcw_home> just in case you are not having enough fun yet
[22:31:04] <pfred1> I think Ubuntu's policy would be to upgrade now
[22:33:05] <pfred1> nah there has to be something going on here 10.04 is still supported there must be a problem with sources.list
[22:43:41] <tjtr33> L84Supper, this is your kinda stuff Lawrence Livermore & Cranfield Uni http://www.cern2012.euspen.eu/content/News-and-events/euspen-events/CERN%202012/Presentations/B1%20Keith%20Carlisle%20-%20Machine%20Tool%20Dev.pdf

[22:46:00] <pfred1> pcw_home something is downloading
[22:46:27] <pfred1> aptitude remove linux-source-2.6.32
[22:46:32] <pfred1> Need to get 0B of archives. After unpacking 86.0kB will be freed.
[22:46:52] <pfred1> something is just basically wrong with that picture
[22:47:50] <pfred1> pcw_home this tarball link you posted is a lot more realistic
[22:48:13] <tjtr33> pcw_home, webpack 14.4 wont load any premade IP. Xilinx agrees & suggests redo a full install. what version do you use?
[22:48:43] <tjtr33> 78.1 meg
[22:49:12] <tjtr33> pfred1 ^^
[22:49:36] <pfred1> yeah what worries me is this is the original unpatched with Ubuntu's patches
[22:50:23] <pfred1> see Ubuntu monkeyed with this kernel to get the nouveau driver into it
[22:50:32] <r00t4rd3d> why bother if your going to use the same kernel that comes with linux cnc?
[22:50:50] <pfred1> r00t4rd3d because I'm going to reconfigure and recompile it
[22:50:57] <r00t4rd3d> oh
[22:51:13] <pfred1> UTSL
[22:51:26] <pfred1> Use The Source Luke
[22:51:40] <r00t4rd3d> thats only fun once
[22:54:38] <tjtr33> ok, 9.2
[22:57:39] <tjtr33> wot? xilinx ISE 9.2i is 337meg? and the 14.4 is .. well 14.4GIG ?
[22:58:45] <tjtr33> tonight is size crazy, pfred's linux src and xilinx's dev tool suite
[23:06:10] <pfred1> ha ha! I got the diff file that goes with that other tarball
[23:13:29] <AR_> yes
[23:13:38] <AR_> xilinx just adds to the package
[23:13:42] <AR_> and it gets huge
[23:19:51] <pfred1> ┌─────────────────── Ubuntu Supplied Third-Party Device Drivers ───────────────────┐
[23:22:24] <pfred1> it is almost a moral imperitive to get this kernel running in Gentoo
[23:53:14] <tjtr33> the 337meg file is xilinx's own 'service pack 4' which needed for the ISE 9.2i Webpack which is 'only' 1.7G
