#linuxcnc | Logs for 2013-04-26

[00:55:47] <Loetmichel> mornin'
[03:32:00] <DJ9DJ> moin
[08:52:11] <Gromits> I have a machine that has been running 2.5.2 without issues for some time. I think someone did a system update but I am not sure what might have gotten updated. Now Linuxcnc exits when it goes to launch my gladevcp panel.
[08:52:38] <Gromits> The errors are here: http://pastebin.com/g2CdL7dn
[08:53:28] <Gromits> I think the one that matters is: (gladevcp:1651): libglade-WARNING **: Expected <glade-interface>. Got <interface>.
[08:53:37] <Gromits> Anyone have an idea what this means?
[08:59:10] <Tom_itx> incompatible libglade?
[09:01:41] <Gromits> incompatible with the config?
[09:01:49] <Tom_itx> mine is using 1:2.6.4-build1
[09:02:02] <Gromits> what is at 2.6.4?
[09:02:49] <Tom_itx> what do you mean? ... remember i'm no linux guru :)
[09:03:13] <Tom_itx> that's the ver of libglade2-0 here
[09:03:24] <Gromits> ah, let me look at mine...
[09:03:32] <Tom_itx> i'm checking the package manager
[09:03:47] <Tom_itx> and my system should be fairly current with updates
[09:04:39] <Gromits> Mine is running the same 1:2.6.4-1build1 (notice 1 in front of build - does yours have that, or is it build1)?
[09:05:23] <Tom_itx> yes same
[09:05:25] <Tom_itx> i missed that
[09:06:05] <Tom_itx> and the glade ver is 3.7.0.is.3.6.7-Outbur
[09:08:15] <Gromits> Yep, I have the same glade as well....
[09:08:23] <Gromits> This was working fine yesterday.
[09:08:48] <Tom_itx> wiggle your ram chips and MB connections
[09:09:02] <Tom_itx> or look for something out of place
[09:09:04] <Gromits> When I came in this morning it looks like someone clicked update on the Update Manager panel. Can you run Update Manager and see if there are update to glade waiting for you?
[09:09:24] <Tom_itx> mine says when there are updates ready
[09:09:29] <Gromits> To glade?
[09:09:36] <Tom_itx> oh i dunno about that
[09:09:44] <Gromits> I dare you to update ;-)
[09:09:52] <Tom_itx> i should be current
[09:11:17] <Tom_itx> maybe the 'someone' shouldn't have admin rights
[09:14:21] <cradek> Gromits: did they update the whole os, or just the packages?
[09:14:35] <cradek> Gromits: if they updated the os, you will have to reinstall
[09:15:05] <Gromits> Not the OS, it is still at 10.04. But there are no update in Update Manager
[09:20:01] <L84Supper> does Ubuntu let you set "check for updates" to never?
[09:20:26] <cradek> gladevcp[1651]: segfault at 20 ip 01159a59 sp bff32b60 error 4 in libgtk-x11-2.0.so.0.2000.1[fdb000+3cd000]
[09:20:46] <cradek> in general you should be able to install updates to packages (but not update the OS version)
[09:20:59] <cradek> I agree gladevcp is crashing now
[09:21:02] <Tom_itx> that was why i suggested he wiggle his memory connections
[09:21:04] <cradek> did you reboot after the updates?
[09:21:12] <Tom_itx> mmm
[09:21:17] <Gromits> Yes, I have rebooted.
[09:21:34] <Gromits> You are seeing glade exit as well?
[09:21:51] <Tom_itx> remind me not to update
[09:21:55] <Gromits> Do you know what got updated?
[09:22:44] <Gromits> I found this on stackoverflow: http://stackoverflow.com/questions/2668618/python-glade-could-not-create-gladexml-object
[09:23:02] <Tom_itx> L84Supper, yes it's in 'startup applications preferences'
[09:24:38] <Tom_itx> System -> Preferences -> Startup Applications
[09:24:44] <Gromits> But, when I try to save as libglade it complains that a huge pile of object classes not being supported in libglade format. (and it crashes for other reasons seemingly related to that
[09:25:09] <L84Supper> don't give everyone admin rights or at least kill any auto updates
[09:25:51] <L84Supper> Gromits: who knows what else they did?
[09:26:26] <L84Supper> maybe they also decided to see what would also happen if you delete things
[09:26:44] <Tom_itx> cradek was apparently able to reproduce the error
[09:26:46] <Gromits> All the configs are there from what I can tell. I compared to a recent backup
[09:27:18] <Gromits> I am fairly sure this is an issue specifically with Glade
[09:27:27] <cradek> no I wasn't, I was identifying the important line from the big pastebin
[09:27:31] <Tom_itx> oh
[09:27:43] <L84Supper> yes, a few lines up from the bottom
[09:28:16] <cradek> you could try identifying the package that broke by reverting updates. this can be a little tedious but is generally possible
[09:28:38] <cradek> apt can install a specified version you specify using =
[09:29:01] <Gromits> Is the package that broke specifically libgtk-x11-2.0....?
[09:29:10] <cradek> maybe, maybe not
[09:29:47] <Gromits> Does the update manager show an update to Glade, or glade specific libraries for you Tom_itx?
[09:30:04] <cradek> Gromits: check your logs and see what was updated, instead of guessing
[09:30:16] <Gromits> What log would show that?
[09:30:19] <Tom_itx> just a sec
[09:30:42] <cradek> /var/log/apt/history.log maybe
[09:33:05] <atom1> my apr 20 log shows nothing glade related
[09:34:01] <Gromits> I don't see anything with "glade" in the name, do any of these look like possibilities? http://pastebin.com/tMjehxvR
[09:34:48] <atom1> or 'lib'
[09:35:32] <cradek> are you sure this is the recent upgrade? it shows a linuxcnc-dev update which seems contrary to what you were saying earlier
[09:37:10] <atom1> i've also got libglade2-dev 1:2.6.4-1build1 installed
[09:38:05] <atom1> i don't have the linuxcnc-dev 1:2.5.2 installed
[09:38:34] <Gromits> var/log/apt/history.log has a date stamp of today at 9am - that is what I posted....
[09:38:36] <atom1> fwiw
[09:39:08] <Gromits> I don't know what got updated, I was just saying that the OS didn't get updated....
[09:39:12] <cradek> well you posted a grep of it
[09:39:33] <cradek> I have no idea if that shows the right things, or if the line you got was even from today
[09:40:18] <Gromits> oh, yes, here is the whole thing: http://pastebin.com/NtSVEg3u
[09:40:55] <cradek> aha, so that was everything
[09:44:00] <Tom_itx> libxml2-dev
[09:44:05] <Tom_itx> would that affect it?
[09:44:51] <Gromits> what is your version of libxml2-dev/
[09:45:07] <Tom_itx> i shut it down
[09:45:09] <Tom_itx> just a sec
[09:48:00] <cradek> custom_postgui.hal:63: Pin 'axisui.reload' does not exist
[09:48:03] <Gromits> mine is at 2.7.6.dfsg-1ubuntu1.8
[09:48:06] <cradek> you sure the problem is not this?
[09:49:00] <cradek> A2THC.hal:2: Warning: File contains DOS-style line endings.
[09:49:01] <atom1> 2.7.6.dfsg-lubintu:8
[09:49:12] <cradek> also beware someone's editing your hal files on a windows machine, which can monkey them up
[09:54:21] <lando5446> anybody here?
[09:55:54] <Gromits> Is there a way to fix the DOS-style line endings issue? I am editing on linux, not sure why that error exists....
[09:56:40] <cradek> remove all the ^M from the file
[09:56:50] <cradek> might try using the program "fromdos"
[10:00:36] <lando5446> In the HAL file, is there a way to write an analog value to a variable when a bit goes high?
[10:07:33] <cradek> what do you mean by a variable?
[10:08:00] <cradek> maybe back up a bit and say what problem you're trying to solve
[10:08:55] <Gromits> hmm, looks like this issue that you identified cradek: custom_postgui.hal:63: Pin 'axisui.reload' does not exist
[10:09:00] <Gromits> has something to do with it.
[10:09:48] <Gromits> I comment that out and it comes up. Axis won't reload our file anymore when I touch off X/Y in our glad panel (the point of that variable), but at least it is working
[10:10:05] <Gromits> Why that worked fine yesterday and not today is a mystery...
[10:10:27] <mrsun> when pressing something into something, ... will it scratch ? :P
[10:10:50] <Gromits> like pressing one vehicle into another at speed? :-)
[10:10:52] <cradek> gladevcp doesn't handle errors very gracefully does it
[10:10:58] <lando5446> Im using Classic Ladder to do some logic. When its complete it, an output bit is set high. I would then like to write the value of the Z-axis to a pyvcp widget to display on the screen.
[10:10:59] <Gromits> ugh
[10:12:02] <cradek> lando5446: you can have floating point varilables in classicladder, or you might be able to use the sample_hold component?
[10:13:03] <Gromits> thanks for your help. more investigation required to fix it, but bandaids are better than dead machine!
[10:14:02] <cradek> welcome
[10:15:22] * Gromits moves on to next problem....hoping that one solves itself
[10:15:45] <lando5446> Sample-hold looks like just the function I was looking for. Thanks
[10:59:52] <tjtr33> i saw linear inductosyns in old APT programming book.
[11:00:01] <tjtr33> they >might< be mfctrd by std pcb techniques ( read: cheap linear scales of hi precision )
[11:00:02] <tjtr33> http://www.analog.com/static/imported-files/seminars_webcasts/813973100sscsect6.PDF
[11:00:22] <tjtr33> what i saw looked photoetched
[11:06:34] <tjtr33> have not scanned book yet but plates like these ( scale and reader head ) http://www.microcontrol.it/prodotti.html
[11:07:24] <pcw_home> With a minimum 5 mill trace width and a 10 mill loop spacing you get a 35 mill pitch (360 electrical degrees)
[11:07:27] <pcw_home> so you have to have pretty good interpolation
[11:09:38] <tjtr33> thx! i see the pix abobe is made by Ruhle ( good ol name )
[11:10:58] <tjtr33> re: interp, the recent chips mentioned for resolvers might handle the sine interp ( ic haus .de ?)
[11:11:06] <pcw_home> dont know where the best pitch tradoff is (larger pitch mean larger signal for so better S/N ratio)
[11:12:14] <pcw_home> I think those are DC interpolaters so may need a sync detector front end
[11:12:49] <pcw_home> synchronous detector I should say
[11:13:43] <tjtr33> i saw them on moog jig bores, not a fast contouring machine
[11:14:07] <tjtr33> just a thought :)
[11:14:55] <pcw_home> You probably will not get really high resolution but they are very tough (they will cheerfully run under water made correctly)
[11:16:25] <skunkworks> tjtr33: this is what was originally on our mill.. http://www.electronicsam.com/images/KandT/conversion/accpinset1.jpg
[11:22:22] <tjtr33> pcw_home, thx, might look for an old scale & head just to poke at
[12:00:55] <IchGuckLive> hi all
[12:01:12] <IchGuckLive> tjb1: ?
[12:03:04] <IchGuckLive> @all i got a problem with the joypad pendant it loses contact and disapears sometimes how can i overcome this probelm
[12:03:56] <IchGuckLive> all pins from usb input halcomponent are gone without a error thats nice but bad if i want to press the e-stop on it
[12:04:28] <IchGuckLive> i got a 6 hardwire also but the mashine is quite big
[12:04:48] <IchGuckLive> and the pendand is always in a hand
[12:05:34] <IchGuckLive> 10m activ USB wire in use maybe a forklift wars over it and nowone got this known 2
[12:09:18] <tjb1> IchGuckLive: ?
[12:10:05] <IchGuckLive> hi today second plasma fire up
[12:10:23] <IchGuckLive> this time cina plasma stamos USA
[12:11:35] <IchGuckLive> i broke first the warrenty sign and lookt into it the 55-125 seams to be the same electronik as the plugs are all on the board and seald off with wax
[12:12:24] <IchGuckLive> so on pricing Hypertherm 45 charge 2300.- Eur the stamos 85 670.-
[12:12:26] <tjb1> stamos 55-125?
[12:12:32] <IchGuckLive> Ampere
[12:12:52] <tjb1> stamos is brand right
[12:13:18] <IchGuckLive> yes
[12:14:02] <tjb1> has to be a reason for different price :P
[12:14:12] <tjb1> especially one that extreme
[12:14:50] <IchGuckLive> i unboxed it opend the case got the relay placed and got into work
[12:15:14] <tjb1> I can get a hypertherm 45 right now for 1235.89 euro
[12:15:50] <tjb1> well its $1610 usd
[12:15:59] <IchGuckLive> 4sheets 1mx2m at 45m cutting length in 1h at 35A with 4Bar air pressure NP
[12:16:10] <IchGuckLive> on one nozzle 1.2mm
[12:16:57] <IchGuckLive> china suprise hase been that the tols are inside the case
[12:17:26] <IchGuckLive> how in this world opens the warrenty and 30 screws to get the wrenches and bits
[12:17:41] <IchGuckLive> Suprise suprise
[12:18:22] <IchGuckLive> so if you(postman) turns the packet upside down it is getting you a nice firerworks on 380V
[12:18:58] <IchGuckLive> tjb1: i will get you if it hits 200h of cutting
[12:19:21] <tjb1> tols?
[12:19:56] <IchGuckLive> http://www.expondo.de/products/en/Welding/Plasma-cutters/S-PLASMA-85H.html
[12:21:05] <tjb1> Wait, what is getting on 380v?
[12:21:30] <IchGuckLive> the plasma cutter gets 3phases
[12:21:45] <IchGuckLive> L1 l2 l3
[12:21:57] <tjb1> and something is loose on the inside?
[12:22:26] <IchGuckLive> yes i found 3 wrienches NEW and 4 bits
[12:22:50] <tjb1> H
[12:22:53] <tjb1> ah
[12:23:51] <IchGuckLive> 10-11 ,12-13 ,14-15 Screw 4.5 7 Spz2 and 1x3
[12:24:19] <IchGuckLive> but as i sayd insider the seald case that is china
[12:24:47] <IchGuckLive> loos is not correct
[12:25:03] <IchGuckLive> inside wax like material clue
[12:25:19] <IchGuckLive> beside the airvent
[12:26:05] <IchGuckLive> The plug for the torch stard is also standard CA-serias 3eur to get connected to the cnc
[13:02:06] <IchGuckLive> ubuntu 13.04 is out
[13:02:58] <pcw_home> sounds unlucky
[13:04:02] <IchGuckLive> speed for 8kernal PC at the best
[15:30:14] <carper64_lb> my new radio control tx is nearly as bad as linuxcnc to setup more brain numbing fun
[15:31:31] <carper64_lb> and the flippin manual is nearly a big too lol
[15:35:59] <carper64_lb> server urns up next week so between linuxcnc my new radio gear and setting up the server i will be totally brain dead by the end of next week
[15:41:13] <carper64_lb> i think simple engineering is best a big hammer and a monkey wrench is all that is needed
[15:41:20] <carper64_lb> lol
[15:46:03] <Tom_itx> you asked for the pain
[15:49:35] <carper64_lb> Tom_itx no i just put off the software jobs untill last as i hate it just happens that all 3 have turned up in the same week lol
[15:54:25] <andypugh> I had a radio control TX once with a knob that you twiddled and pressed, and a very small LCD to tell you what mode you were setting. Like a VFD, only more complex, and worse. It was a good transmitter, but a pain to configure.
[15:56:35] <carper64_lb> andy the software is a nightmare on this 1 its a futaba/robbe fx-30
[15:57:33] <andypugh> This was a Multiplex Cockpit. I can't complain as it made the effective range of our Robot 100m not 1m.
[15:58:59] <carper64_lb> maed to get the software updates into it but the set of a model profile is totally different to my jr tx
[16:01:37] <carper64_lb> it allows you to setup upto 8 servos on the aerilons each witha differnt curve setting
[16:02:49] <carper64_lb> gonna have to sit down and have a few evenings on it jst to get to grips with the setting up of a model
[16:03:18] <r00t4rd3d> Tomato head: http://i.imgur.com/udvYMKd.jpg
[16:04:07] <carper64_lb> lol @ tomato head
[16:05:07] <carper64_lb> whats the robot andy wheeled or walking ?
[16:08:21] <andypugh> Not really a "Robot" at all. More a model car with spikes: http://robotwars.wikia.com/wiki/S.M.I.D.S.Y.
[16:08:48] <carper64_lb> got ya
[16:09:37] <archivist> This page needs content
[16:10:03] <andypugh> You need the last .
[16:10:11] <archivist> last fullstop I see
[16:11:50] <andypugh> The organisers wanted robots, I am sure, and there was planned to be an Autononous class, but the hardware and tech was too special and expensive. They should try again, nobody would _really_ mind getting an axe through their Arduino or RPi.
[16:13:04] <carper64_lb> lol no i dont think they would mind either andy
[16:14:38] <andypugh> Compared to getting an axe through the proprietary RC-to-digipot interfaces we had, that we didn't understand, and knoew the supplier was out of stock of....
[16:17:30] <andypugh> LOL, I just turned on the TV to watch something mindless, and what came up was Raspberian booting, I forgot I had that plugged in.
[16:35:11] <DJ9DJ> gn8
[16:58:47] <Tom_itx> andypugh, what drivers did you use on those?
[17:00:08] <largecheesepuff> so what is correct value for enter for spindle scale if I'm using a 100 count encoder
[17:00:44] <Tom_itx> scale is to do with the motor and drive i believe
[17:03:29] <Tom_itx> there is also ENCODER_SCALE
[17:04:00] <Tom_itx> ENCODER_SCALE = 20000 - in PNCconf built configs Specifies the number of pulses that corresponds to a move of one machine unit as set in the [TRAJ] section.
[17:04:45] <andypugh> Tom_itx: On what>
[17:04:46] <andypugh> ?
[17:04:52] <Tom_itx> those battlebots
[17:05:03] <Tom_itx> largecheesepuff, http://www.linuxcnc.org/docs/html/config/ini_config.html
[17:05:12] <diginet> this is slightly OT, but does anyone here know anything about powder metallurgy?
[17:05:20] <andypugh> 4QD: http://www.4qd.co.uk
[17:06:08] <diginet> I'm trying to figure out how one introduces metal powder into a vacuum chamber, wouldn't that necessarily trap a ton of gas in all the pores?
[17:06:30] <andypugh> diginet: I don't think I know much about it, but then I am comparing my knowledge to that of the woman I shared my office with who was doing postdoctoral research on the subject.
[17:06:58] <diginet> ah, that's okay lol
[17:07:14] <andypugh> It's a powder, not a foam. Nowhere for gas to hide.
[17:07:19] <diginet> I just can't find out how that is done, I haven't seen anyone address it
[17:07:31] <diginet> I know, but I mean. . .surely some would?
[17:07:47] <andypugh> Why? How?
[17:08:09] <diginet> well I mean, if the particles are big enough, wouldn't some just get trapped in little crevices?
[17:08:25] <diginet> plus, more surface area, so more ways for gas to get trapped in oxide layers
[17:08:56] <andypugh> Well, there is quite a lot of gas in any oxide :-)
[17:09:27] <diginet> I mean, besides oxygen
[17:09:32] <diginet> dissolved atmospheric gases
[17:10:12] <andypugh> I think that you are trying to avoid macro-sized bubbles. There is likely to be an equilibrium level of dissolved gas in any metal, matching the composition of the atmosphere.
[17:10:51] <diginet> yeah, that's true, but wouldn't it be much more of a problem with, as I mentioned, the much higer surface area?
[17:10:53] <largecheesepuff> Tom_itx: thanks...
[17:11:03] <andypugh> The vacuum processing of powder met is just so the metal _can_ coalesce, not to create a fully degassed end product.
[17:11:25] <diginet> sure, but you still need to get a high vacuum
[17:11:36] <diginet> plus there are processes which fully melt it, like electron beam melting
[17:11:44] <andypugh> I doubt they get a really high vaccum.
[17:12:33] <andypugh> The vapour pressure of the metal itself at the sintering temperature is likely to make it quite a low vacuum.
[17:13:08] <largecheesepuff> hmm seems like it should be correct..
[17:42:45] <JT-Shop> holy crap Batman it rained all the way home today...
[17:50:46] <andypugh> It rained all the way to work today. I was so glad that, at 11pm last night, I decided to finish reassembling the R1. I have good wet-weather gear for the motorbike, I have nothing suitable for cycling in.
[17:51:39] <andypugh> And I just won a really stubby Renishaw stylus, so now I can probe thivk things as well as very, very thing things.
[17:51:47] <JT-Shop> I was glad we trailered the Spyder to SpyderFest, it would have been a cold wet ride home and the wife could not have napped part way
[17:51:57] <JT-Shop> nice
[17:53:20] <andypugh> Actually, the 75mm probe leaves me about 4" over the bed so it's not hopeless, but 6" with the short probe sounds better.
[17:56:52] <andypugh> I am new to probing, and keep thinking about algorithms. I wonder how legitimate it would be to probe down to break, then drag laterally until make to find the top first, then the edge of the stock?
[17:58:33] <L84Supper> diginet has left but what was he really asking about?
[17:58:50] <andypugh> Powder metallurgy
[17:59:12] <andypugh> It's a way to make alloys of metals with very different melting points.
[17:59:19] <L84Supper> you put power in a chamber and create a vacuum, what was he missing?
[17:59:32] <JT-Shop> kind of a rough probe to get the basic dimensions?
[17:59:45] <andypugh> He seemed convinced that gas would get trapped in the powder.
[18:00:07] <L84Supper> if it already was, did he want to remove it?
[18:00:20] <andypugh> JT-Shop: Yeah, it was the dragging the probe across the surface part that I was wondering about.
[18:01:13] <andypugh> L84Supper: Actual pockets of gas in the powder was his concern. Seems unlikely to me.
[18:02:05] <L84Supper> andypugh: depends on his source for powder, but it would be negligible
[18:02:11] <andypugh> L84Supper: Here's an idea. Selective laser sintering of multiple metal powders to have alloy constitiuents varying within the part.
[18:04:02] <andypugh> L84Supper: No, how concern was that if you mixed the powder in atmosphere, then the gas would get trapped between the grains when you tried to degas. I guess it might take some time to diffuse out, but the powder won't have any closed porosity.
[18:06:04] <pfred1> laser scinters lay the powder down in layers
[18:06:41] <andypugh> You might be surprised how far you can make elements move in a post-sinter heat treatment.
[18:06:54] <L84Supper> andypugh: yeah, you could agitate the powder to release any gas trapped in between grains
[18:07:14] <pfred1> L84Supper the way that stuff gets laid down it is like packed
[18:07:21] <andypugh> L84Supper: I think it is probably pressed into shape by that stage?
[18:07:57] <andypugh> Just to be clear, powder met and DLS are rather different processes.
[18:08:37] <andypugh> Powder met you press a metal powder mix into shape, then heat until the metals all diffuse into each other.
[18:09:08] <andypugh> Juat a bit below the meltiong point of the main constituent, I think.
[18:09:16] <L84Supper> what was diginet doing>
[18:09:46] <andypugh> He was asking about Powder Metalurgy. I doubt he is doing either.
[18:10:26] <L84Supper> if you want to degass a powder you agitate while in a vacuum
[18:10:34] <andypugh> http://en.wikipedia.org/wiki/Powder_metallurgy
[18:11:23] <L84Supper> yeah, been around for a while
[18:11:25] <andypugh> I have an idea that the typical milling machine hold-down kits are powder met. I don't know why I think this.
[18:11:46] <andypugh> L84Supper: 3000BC in fact :-)
[18:15:14] <r00t4rd3d> another 250 spent today on aluminum parts and pieces :/
[18:15:32] <L84Supper> DLS is another patent mine field, another reason we went to China
[18:16:56] <L84Supper> there are many techniques that you probably won't see in DLS printers for years due to patent trolls
[18:17:36] <andypugh> Has anyone done much work on the GGG / MIG crossover?
[18:19:28] <L84Supper> not really, there's this big boom in GGG right now just to print crap
[18:21:19] <L84Supper> but there is work going on with hybrids that combine different techs since there is no one perfect tech
[18:21:59] <pfred1> nanotech
[18:22:43] <L84Supper> you might start seeing printers that print parts with metal cores that have polymers on the outside
[18:23:33] <L84Supper> for example a metal flashlight body with plastic grip
[18:24:23] <L84Supper> printers like these are will really revolutionize manufacturing if they print a part in seconds and at low cost
[18:24:52] <pfred1> as opposed to now where they take forever and cost a fortune?
[18:24:53] <WalterN> L84Supper: for fibre optic cables... can I get one thats big enough and a single strand?
[18:26:05] <L84Supper> IMHO the GGG hype is giving people a bad impression of what 3dp is all about
[18:26:08] <WalterN> or would multi-strand not be an issue?
[18:27:13] <L84Supper> WalterN: multi-strand of multi-mode?
[18:27:18] <L84Supper> of/or
[18:27:22] <WalterN> no idea
[18:27:40] <WalterN> the cable that came with my laser has more than one strand
[18:27:55] <L84Supper> didn't I post you a few links the other day?
[18:28:31] <WalterN> :-x
[18:28:41] <L84Supper> WalterN: you need a fiber with the right connector on the end
[18:29:49] <WalterN> is SMA 905 common
[18:29:50] <WalterN> ?
[18:30:35] <WalterN> and what does multi-mode mean?
[18:33:02] <L84Supper> http://tinyurl.com/btyz7dw for just the cable, but you have to make your own ends
[18:33:58] <WalterN> http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1383
[18:34:06] <WalterN> I dont see 200um listed
[18:34:35] <L84Supper> WalterN: does you laser use a SMA905?
[18:34:52] <WalterN> thats what it says
[18:35:03] <WalterN> L84Supper: http://tiwake.com/Capture.JPG
[18:35:16] <WalterN> at the very bottom of the green circle
[18:35:43] <L84Supper> WalterN: http://tinyurl.com/cskywwz a bunch of different size fiber
[18:35:49] <WalterN> though..
[18:36:00] <WalterN> the one I have looks like its kinda soldered on there
[18:36:51] <Tom_itx> JT-Shop, been raining all day here as well
[18:36:53] <L84Supper> WalterN: so you need SMA905 on one end. Whats on the other?
[18:37:00] <WalterN> L84Supper: http://tiwake.com/IMG_0365.JPG
[18:37:02] <JT-Shop> http://www.youtube.com/watch?feature=player_embedded&v=HKEuzxC4eGc
[18:37:13] <WalterN> you can kinda see it there
[18:37:13] <JT-Shop> it finally quit here
[18:37:53] <WalterN> or should I take a better picture?
[18:38:59] <andypugh> WalterN: Multi-mode fibre can carry more than one wavelength losslessly
[18:39:03] <L84Supper> andypugh: I'd say that has been lots of techniques already worked out for DLS, nut you won't be seeing them in printers anytime soon
[18:39:46] <andypugh> Is this my day to look clever? My PhD was optical fibers, then I became a metallurgist :-)
[18:39:59] <L84Supper> nut/but the OEM's don't cooperate and there are so many patents that overlap it's going to make the patent wars over smart phones look small
[18:40:09] <andypugh> Quick, somebody ask about skin grafts :-)
[18:40:14] <Tom_itx> heh
[18:40:35] <JT-Shop> what's a farkle?
[18:40:47] <Tom_itx> a sparklie fart
[18:41:00] <L84Supper> meanwhile in China they will just take over the tech the same as they did with computers
[18:44:40] <Tom_itx> JT-Shop, when you get a chance could i take a look at your touchoff buttons?
[18:44:45] <Tom_itx> no rush...
[18:44:52] <Tom_itx> gonna watch a show right now anyway
[18:44:54] <JT-Shop> you bet
[18:45:02] <JT-Shop> tomorrow then?
[18:45:10] <Tom_itx> i can check the logs
[18:45:20] <Tom_itx> i'll be milling later this evening anyway
[18:45:29] <Tom_itx> or tomorrow
[18:45:32] <Tom_itx> either way
[18:46:02] <JT-Shop> ok, let me fire up the lathe so I can copy the configs
[18:46:21] <Tom_itx> i'll check in after bit
[18:47:16] <Tom_itx> bourne is all queued up
[18:48:04] <JT-Shop> actually it should be on my web site
[18:48:19] <JT-Shop> http://gnipsel.com/shop/hardinge/hardinge.xhtml
[18:51:29] <L84Supper> still 64F (18C) outside, time to enjoy some of this
[18:52:44] <L84Supper> andypugh: there are lots of medical apps that require DLS with titanium
[19:04:15] <pfred1> bash - GNU Bourne-Again SHell
[19:04:38] <pfred1> the real Bourne Identity
[19:07:33] <PCW> andypugh it appears that setsserial does not check the firmware name vs remote device name
[19:08:51] <andypugh> No, I thought I could assume competence, and could not necessarily assume file naming
[19:09:11] <andypugh> C is a terrible place to try to spot partial string matches.
[19:09:23] <PCW> Its not terribly dangerous
[19:10:24] <PCW> except that writing too big firmware may wipe the (simulated) EEPROM defaults
[19:10:33] <andypugh> Is there any danger of wrong-firmware over-writing boot code?
[19:10:38] <JT-Shop> yikes
[19:10:42] <PCW> No
[19:11:19] <PCW> but it could overwrite the EEPROM defaults, so you would have to fix those to recover
[19:12:49] <PCW> take a look at my (fairly crappy scripts) when you get some time (must be late there)
[19:12:50] <PCW> freeby.mesanet.com/software/parallel/ssr14.tgz
[19:15:22] <PCW> ./updatess 7i73 5i25 2
[19:15:23] <PCW> for example
[19:16:23] <PCW> or ./update7i77
[19:26:09] <mpictor> PCW: the mesaflash Makefile needs a slight change for my system (and/or 64-bit systems in general)
[19:26:33] <mpictor> instead of using the absolute path to libpci.so, use -lpci
[19:28:41] <PCW> that should probably be directed to micges (who is likely asleep now or should be)
[19:29:11] <micges> PCW: hah, should be is the word
[19:29:15] <micges> mpictor: noted
[19:31:08] <mpictor> micges: I *think* -lpci would work on all linux flavors we care about
[19:31:58] <micges> ok, I just got small but growing experience with Makefiles
[19:32:07] <mpictor> but why does that executable even need libpci? I didn't think any mesa pci cards had flash...
[19:32:07] <micges> and linking
[19:32:42] <PCW> 5i25 and 6i25 do
[19:32:47] <mpictor> oh
[19:33:09] <mpictor> good thing I'm not your salesperson :P
[19:33:13] <PCW> no bridge chip so they need flash
[19:33:18] <mpictor> I see
[19:59:20] <WalterN> L84Supper: is it a bad idea to use two cables?
[19:59:45] <WalterN> the cable that came with it I dont think is supposed to be removed
[20:31:51] <WalterN> L84Supper: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=314#1346
[21:05:10] <Tom_itx> JT-Shop, thanks
