[02:05:10] <Jymmm> New digital scope, what am I doing wrong... I engage a laser diode but all I get is a blip when I turn it on/off
[02:05:20] <Jymmm> I can see the diode is on, but no signal on the scope

[03:42:13] <cmorley> yes edit the GLADE file, changing the 'text template' of the relevant Hbar widget to something like %.1f
[03:43:41] <Tom_itx> change <format>"4.1f"</format> to <format>".1f"</format> in the xml file?
[03:44:01] <Tom_itx> or 0.1
[03:44:02] <Tom_itx> ?
[03:45:13] <Tom_itx> Jymmm, what scope did you go with?
[03:45:54] <cmorley> I believe either will work and its easy to try
[03:46:41] <Tom_itx> yeah, somewhere in the code i had to scale mine too iirc
[03:48:52] <Tom_itx> soundhound, my configs are here if you wanna peek: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/
[03:49:14] <Tom_itx> display.xml and postgui.hal would be the relevant files

[07:32:05] <Loetmichel> Jymmm: scope set to ac?
[07:32:53] <Jymmm> Loetmichel: It's on DC now, I changed it to DC previously and it switched back to AC
[07:33:08] <Loetmichel> hrhr
[07:33:29] <Jymmm> It's a weird scope, I'm not impressed.
[07:33:46] <Loetmichel> i just meant: that sounded like you are measuring the wrong thing.
[07:34:15] <Jymmm> settings, menus, UI are kind a funky on it.
[07:34:46] <Loetmichel> we have a proverb in german: "Wer misst misst Mist! (Und wer viel misst misst mehr Mist!)"
[07:34:47] <Jymmm> The online help pops up at the wrong time, and doesn't even help
[07:35:44] <Loetmichel> "he who measures measures Manure. (and the one who measures much measures more manure!)"
[07:36:07] <Jymmm> lol
[07:36:19] -!- Thetawaves [Thetawaves!~Thetawave@186-51-178-69.gci.net] has joined #linuxcnc
[07:37:05] <Loetmichel> quite literally translated.
[07:37:24] <Jymmm> My first time playing with a digital scope; not what I expected in the least
[07:37:35] <Loetmichel> new scope?
[07:37:43] <Loetmichel> maybe the thing has a fault?
[07:37:54] <Jymmm> I doubt it
[07:38:00] <Jymmm> just funky
[07:38:04] <Loetmichel> damo keyboard circuit for example?
[07:38:09] <Loetmichel> damp
[07:38:27] <Jymmm> I've had it running for 8+ hours
[07:38:44] <Loetmichel> s/damp/dirty then
[07:39:01] <Jymmm> Nah
[07:39:14] <Loetmichel> the worst UI i had ever was on a chinese DM203 scope.
[07:39:39] <Loetmichel> that seems to have evolved from an MP3-player ;-)
[07:39:43] <Jymmm> It's just a low end scope.... Agilent rebadged rigol
[07:39:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14319
[07:40:06] <Loetmichel> that thing is even lower end
[07:40:15] <Loetmichel> but it does what is advertized
[07:40:19] <Loetmichel> -z+s
[07:40:42] <Jymmm> That actually looks nicer UI
[07:41:03] <Jymmm> let me grab a usb stick...
[07:41:15] <Loetmichel> althoug it has only 30 Ms/s you can see 12 Mhz more or less fine
[07:42:23] -!- jduhls has quit [Ping timeout: 252 seconds]
[07:43:03] <Loetmichel> but for less than 130 eur its a fine tool (even with the strange ui/keys) http://www.ebay.de/itm/NEW-Mini-Digital-Storage-Color-Oscilloscope-Metal-Handheld-Scope-DS-203-Nano-A-/380456969542?pt=BI_Oscilloscopes&hash=item589500a546
[07:44:35] <Einar1> Jymm: Did you compensate the probe?
[07:45:43] <Jymmm> yep
[07:46:07] <Loetmichel> i bought it for the company, because the other scope we have costs about 150kEur (tectronics 4 channel 1 ghz) ... and measurung high voltage is a bit frightening.
[07:46:37] <Loetmichel> the 131eur pice can be destroyed by accident without worrying too mich ;-)
[07:47:23] <Jymmm> http://imagebin.org/311718
[07:47:42] <Jymmm> Just to grab that, I had to go thru 5 menus
[07:48:14] <Jymmm> it's just real kludgy to operate
[07:48:52] <Loetmichel> hu? imagebin is flagged as attacking website in FF?
[07:49:03] <Einar1> It looks like you may not have a good ground point. Avoid using pigtails! Always connect directly to a good ground.
[07:49:27] <Loetmichel> the trace on the pic liiks like a bad case of ringing (or an uncompensated probe)
[07:50:13] <Einar1> He said he compensated it. And yes, it's ringing. At a faster scan rate that will probably be obvious.
[07:50:44] <Jymmm> I'll recompensate and recalibrate the scope later on.
[07:50:54] <Einar1> If probe is comped it can/will ring if ground through a piece of wire.
[07:52:07] <Jymmm> I clipped the pigtail to return of what I was probing
[07:52:25] <Jymmm> ^the
[07:52:31] <Einar1> Or of course it can be actual. For example if the thing he measures drive a capacitive load through an inductor (wire).
[07:53:10] <Jymmm> I'll hve to pull the controller board out tomorrow and measure from there.

[07:53:17] <Loetmichel> Einar1: i have seen that worse.
[07:53:45] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14325
[07:53:53] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14328
[07:53:55] <Einar1> The scope probably have a LP filtering that can be used if the high frequencies are not of interest for what he is measuring.
[07:54:02] <Loetmichel> smps fets
[07:54:37] <Einar1> Boiiinggg!!!
[07:55:04] <Loetmichel> exactly
[07:55:08] <Einar1> That's a school example of ringing! :-)
[07:55:32] <Loetmichel> and we were wondering why the printer falls through EMI testing ;-)
[07:55:59] <Einar1> Ohh! Did it? .... ;-)
[07:56:27] <Loetmichel> s/falls throug/fails
[07:57:14] <Loetmichel> was a BIT of work to get it stop the ringing.
[07:57:49] <Loetmichel> and i am still not sure that the caps i added will not overload the SMPS fets in the long run
[07:58:08] -!- skroon [skroon!~skroon@541F1FA3.cm-5-8a.dynamic.ziggo.nl] has joined #linuxcnc
[07:58:27] <Loetmichel> its never that great to work on a circuit you havent designed yourseld and have no plans on whatever
[07:58:29] <Einar1> I do courses in fieldbus network fault finding. So I have some pretty interesting scope shots of ringing, reflections, stublines and impedance mismatches.
[07:58:59] <Einar1> It can be quite a puzzle to figure out why things look the way they do on a scope.
[07:59:24] <Loetmichel> i wonder how HP got this thing through CE certification.
[07:59:31] <Einar1> Especially when a digital scope may throw you a screwed ball too.
[08:00:25] <Einar1> They don't need to test it. They only need some boss to put his balls in a vice and signature on a document.
[08:00:38] <Loetmichel> yeah, i remember an old GOULD DSO... that had the habit of throwing ghost peaks in the mass. (aliasing effects i would think)
[08:01:09] <Loetmichel> Einar1: HP is a bit big a company to NOT test it
[08:01:31] <Loetmichel> there is no boss that is willing to expose his balls that far
[08:02:49] -!- lyzidiamond has quit [Remote host closed the connection]
[08:02:50] <Loetmichel> i suppose they only measured it on fully charged battery
[08:02:54] <Einar1> I have pushed 3 products through the equivalent to Germanische Lloyds. And I am thoroughly underwhelmed!!
[08:02:58] <Loetmichel> THEN it is quiet
[08:03:03] <Jymmm> Loetmichel: what pocket scope is that?
[08:03:18] <archivist> current boss has no balls
[08:03:19] <Loetmichel> as soon as the battery drains it starts ringing
[08:03:40] <Loetmichel> Jymmm: search in ebay for DS203
[08:03:53] <Loetmichel> see the link above
[08:04:04] <Einar1> Is that the "big brother" of DSO Nano?
[08:04:36] <Loetmichel> no idea
[08:04:58] <Loetmichel> its obviously made of a MP3/MP4 player
[08:06:01] <Loetmichel> archivist: the balls just sit a bit higher ;-)
[08:06:06] <Einar1> One of these: http://www.seeedstudio.com/depot/Oscilloscopes-c-63_65/?ref=side

[08:10:38] <Loetmichel> it is from seedstudio
[08:10:44] <Loetmichel> but an older model i think
[08:11:46] <Loetmichel> dso quad has the same casing
[08:11:58] <Einar1> Loetmichel: Looking at that printerport it looks like the driver chip have a supply problem. It can do for a short time, then gives up. I've seen similar on line interfaces where the DC/DC converter of the galvanic barrier is near dead.
[08:13:13] <Loetmichel> Einar1: my pics werent from the ports
[08:13:22] <Loetmichel> that is a portable printer
[08:13:29] <Loetmichel> with battery supply
[08:14:08] <Loetmichel> and i measured the drains of the switching voltage converterst for supplying the printer and charging the battery
[08:14:39] <Loetmichel> (or was it the sources? cant remember the circuits now)
[08:15:45] <Einar1> Ahh.. I see it now: 10V / Div. Obviously not a digital signal.
[08:16:46] <Loetmichel> it seems hp has desinged these circuits with no headroom at all.
[08:17:16] <Einar1> I bought the 1Ch scope from Seedstudio in hope it could be used for fault finding on cars. But sorry, no. It can't be used for anything but basic teaching of scope principles.
[08:17:17] <Loetmichel> (how do one say "auf kante genäht" in english?)
[08:17:17] <archivist> headroom costs money
[08:18:18] <Einar1> Sewn at the edge?
[08:18:40] <Loetmichel> i meant as a proverb ;)
[08:19:21] <Loetmichel> like i said: the pribnter is fine when the battery is full and its supplied from the mains
[08:19:35] <Einar1> Finished off? I don't know the proverb. But it's like a rug where the edges are not sewn. It will disintegrate. Maybe?
[08:19:39] <Loetmichel> it only rings when it has to charge the battery AND print at the same time
[08:20:03] -!- mariusl has quit [Client Quit]
[08:22:10] <Loetmichel> and as the company i work for does Tempest proofing and certifying.... we have to deal with MUCH lower limits than CE in terms of EMI radiation
[08:24:03] <Einar1> I imagine that a big problem! I would think the strategy is to make the whole system PC, printer, monitor .... all inside a Faraday's cage. So including screened cable between. But that may not be enough?
[08:24:39] <Loetmichel> Einar1: "auf kante genäht" references the overlap you have normaly at the inside of sewn seams. if you omit that overlap (for example because you have gained a few pounds) you have no headroom left.
[08:25:13] <Loetmichel> if you desing a pive of clothing that way its just barely coping with its job.
[08:25:30] <Loetmichel> Einar1: we do
[08:25:44] <Einar1> I see. That makes sense. We don't have that proverb. (Until now ;-)
[08:26:45] <Einar1> Do you have your own EMC testing lab?
[08:26:58] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14778 <- thats a laptop PSU when i am finished with it...
[08:27:01] <Loetmichel> for example
[08:27:08] <Loetmichel> yes, two
[08:27:29] <Loetmichel> one for german "zone" certifying and wone for nato/sdip27
[08:27:33] <Loetmichel> one
[08:27:52] <Einar1> Wow!! Can I come and play with you?
[08:27:59] <Loetmichel> dont think so
[08:28:50] <Loetmichel> you have to have a "background check" by german MAD to enter the measurement chambers ;-)
[08:30:28] <Loetmichel> Einar1: thats a commercial NAS that i have modified: http://www.cyrom.org/palbum/main.php?g2_itemId=14184
[08:30:51] <Loetmichel> (just made an outer box for it and added some powersupply filters)
[08:31:17] <Einar1> What metal?
[08:31:24] <Loetmichel> aluminium 1,5mm
[08:31:58] <Loetmichel> our PC enclosures are custom made from 3mm aluminium...
[08:32:07] <Einar1> Did it go through a salt mist test first, then an EMC test *afterwards* ?
[08:32:20] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14145
[08:32:28] <Loetmichel> no, why it should?
[08:32:45] <Loetmichel> these are not rugged, just zoned
[08:33:10] <Loetmichel> and yes, all the corners are welded shut
[08:33:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12010
[08:34:02] <Loetmichel> thats a complete system, cpu, monitor, keyboard, mouse, printer, scanner.
[08:34:10] <Loetmichel> all shielded
[08:34:45] <Loetmichel> ... and on thet table is about 18 to 20k eur
[08:34:47] <Loetmichel> ;-)
[08:34:49] <Einar1> Neat work! Are you doing the welding?
[08:35:19] <Loetmichel> no, the cases are made by an external manufacturer
[08:35:24] <Loetmichel> i just do prototypes
[08:36:02] <Loetmichel> the monitoprs are especially bad.
[08:36:04] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14412
[08:36:21] <Loetmichel> 144 m3 screws... and that is just on the outside ;-)
[08:37:14] <Einar1> Are the holes punched or do you do them in your router?
[08:37:46] <Loetmichel> in series: punched
[08:37:52] <Loetmichel> prototypes: router
[08:38:15] -!- rob_h [rob_h!~robh@2.124.67.236] has joined #linuxcnc
[08:38:42] <Loetmichel> that was a monitor stand i desinged for a customer: http://www.cyrom.org/palbum/main.php?g2_itemId=10788
[08:39:23] <Loetmichel> ... who (as an afterthougt) wanted to have the heigt of the 7kg monitor adjustable...
[08:39:29] <Einar1> When routing, do you use 1010 aluminum? I find that it clogs up the cutters real quick if not using suds.
[08:39:31] <Loetmichel> so i got working.
[08:39:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10791
[08:39:41] <Loetmichel> :-)
[08:40:39] <Loetmichel> normally i use sheets of AlMg3
[08:40:55] <Loetmichel> dont know the number of that stuff, maybe 6061?
[08:41:31] <Einar1> 6061 is nice to cut. And if I remember correctly also weldable.
[08:42:41] <Einar1> But I think not easy to get in sheetmetal around here. Actually it's not easy to get anything but 10?? sheets here.
[08:42:50] <Loetmichel> lately i had to make some Cable clamps for keyboards as an "external repair"... and had some spare 7075... result: https://www.youtube.com/watch?v=9u_ChO1AKYY
[08:43:12] -!- jduhls has quit [Ping timeout: 245 seconds]
[08:44:22] <Einar1> 7075 cuts nice. But try to weld it!! ;-(
[08:45:04] <Loetmichel> i buy the sheets as "small standard size" from the local metal supplier, means i call them and order two small sheets, cut to 5 strips 400mm*1000mm each" and then drive there the next day and fetch them
[08:46:31] <Loetmichel> btw: that vide: it is MUCH nicer to sit in the office and look at the monitor with a cup of coofe in the hand than sitting in the workshop with hearing protection on and metal flakes in the coffee ;-)
[08:49:06] <Loetmichel> ant the two 2m by 1m sheets cost about 150 eur in 1,5mm, so not THAT expensive
[08:51:14] <Einar1> I bought aluminum sheets in Sweden at half the price I pay here. And the damn stuff is produced here!!! We are being screwed!
[08:54:37] <Einar1> I got a package from Hing Kong the other day. Ebay # 261374073967 . It's raining today, so I thought I will try to finish the production of the stepper drivers. See if I can fix the design flaw so I can use them in my LinuxCNC redo of the Emco lathe.
[08:56:22] <Einar1> I hope they can be salvaged. Some of the problems I cannot understand. Like no standoffs on the PCB. It is just held by the pins of the controller chip.
[08:56:59] <Loetmichel> its from china. what did you expect?
[08:57:04] <Einar1> So if the stepper driver is mounted on the lathe, the vibrations will surely kill it in short time.
[08:57:33] <Einar1> At the price I must admit I expected (or at least hoped for) a stepper driver kit. ;-)
[08:58:45] <Einar1> The fastening of the PCB is easy. Just 4 plastic standoffs. That's why I can't understand. They cost nothing.
[09:01:40] <Einar1> If all I need is 1 capacitor, 4 Schottky diodes and 4 plastic standoffs, I'm good. That lathe needs to be low cost. I will not use it much since I got the Boxford lathe up & running.

[09:18:53] <zeeshan> :D
[09:20:00] <zeeshan> Most aluminum alloys are weldable, but there are a fair number of them that are not, including 7075 aluminum. The reason 7075 is singled out in this example is that it is one of the highest strength aluminum alloys. When designers and welders look for an aluminum alloy to use, many will start by reviewing a table that lists all of the aluminum alloys and their strengths. But what those newcomers d
[09:20:03] <zeeshan> ^^
[09:20:16] <zeeshan> i know welding 7075 will hold together

[09:31:44] <Loetmichel> zeeshan: 7075 is kind of "brittle"
[09:32:04] <Loetmichel> not ductile like other aluminium alloys
[09:32:15] <Loetmichel> so its like welding cast steel
[09:32:23] <Deejay> thats why i like 7075! ;)
[09:32:27] <Loetmichel> "it may hold, but it may fall off"
[09:32:31] <Deejay> not like chewing gum
[09:33:49] <Loetmichel> if i had to join 7075 parts i would try brazing instead of welding
[09:33:55] <Loetmichel> (same for cast iron)
[09:34:09] <archivist> cast steel is ductile, cast iron is brittle
[09:34:16] <Loetmichel> MUTCH easier joint ;-)
[09:34:26] <Loetmichel> archivist: i meant cast iron
[09:34:33] <Loetmichel> like machine beds
[09:35:15] <Loetmichel> is there any cast steel that isnt hammered afterwards?
[09:35:15] <archivist> I put a bit of cast iron in a forge to get it to red heat to weld
[09:35:55] <archivist> cast steel man hole covers anr not hammered
[09:36:38] <archivist> very little hammering done these days afaik
[09:37:19] <archivist> or are you talking about forged parts
[09:37:33] <archivist> eg bolt heads
[09:38:55] <Einar1> 7075 aluminum contains zink. So is basically not weldable.
[09:39:44] <archivist> been handed a new 20mm die to thread some parts, it has no clearance and will not cut!

[09:45:23] <Einar1> Zeeshan: Sticky indicator? Another example why a measuring instrument should never be trusted until proven good. It can usually be saved. Unless like one of mine that probably have been in an overtightened clamp. Cleaning and lubing made no difference.

[09:45:44] <archivist> often production forging is done with a wire feed
[09:46:47] <Einar1> Can a 8.8 bolt (or better) be forged and retain it's good properties?
[09:47:00] <archivist> least material use per part, fast production etc
[09:47:09] <Loetmichel> what i wanted to say: i dont know of any cast STEEL that isnt formed after casting
[09:47:39] <Einar1> Conrods.
[09:47:43] <archivist> manhole covers are true cast only
[09:47:58] <Loetmichel> unlike cast iron which is more or less done after casting

[09:49:00] <archivist> Einar1, the forging process actually gets the right grain structure for strength
[09:51:28] <Einar1> Usually, yes. But I believe some steels are not forgeable. What I was thinking is could a high grade bolt be forged to a crankshaft and be strong. Another question is would it be good as a bearing surface.

[10:50:43] <_abc_> Hello. I run an install of linuxcnc from the lts 10.04 live cd. I have issues with booting and usb stick mounting. Also there is some weird ram corruption when using vim. Does anyone know of fixes?
[10:51:41] <Loetmichel> _abc_: have you tested the machine for hardware errors (i.e runnung memtest for more than 24 hrs at least)?
[10:51:59] <_abc_> Specifically: 1) usb stick inserted gets mounted ro. I have to remove and reinsert to get it to be rw. 2) Window manager comes up without decorations on 1st boot, 50% of the time. Restarting session fixes this. 3) vim causes text file corruption and screen corruption in any terminal emulator under X11 and also in text mode console. This was confirmed for original vim and also for vim compiled from source on that machine.
[10:52:14] <_abc_> Loetmichel: Yes, the machine is dual boot and it runs fine. Also disks are okay.
[10:52:27] <Loetmichel> dual boot means: windows on the otbher side?
[10:52:30] -!- syyl_ [syyl_!~sg@p4FD10D50.dip0.t-ipconnect.de] has joined #linuxcnc
[10:52:32] <Loetmichel> that means noting
[10:52:36] <_abc_> Not just Windows, another linux too
[10:52:38] <_abc_> 3 systems
[10:52:56] <_abc_> The 10.04 gets used infrequently to test drivers, this is a back up machine not a main linuxcnc driver
[10:53:04] <_abc_> And it ie VERY ANNOYING like that
[10:53:05] <Loetmichel> i had it repeadedly that a machine works fine with windos wenn used not much ram but linux crashes more or less instantly
[10:53:22] <_abc_> That is very rare ime.
[10:53:31] <_abc_> Also I am not new to linux so ...
[10:54:04] <_abc_> Also I did the memtest thing and it worked okay for half a day at least. Problem is some software contention. Maybe not enough ram.
[10:54:08] <Loetmichel> i think that depends on WHERE the fault in the ram is
[10:54:20] <_abc_> Well memtest will test ALL of it so it can't be that.
[10:54:25] <Loetmichel> how much has it?
[10:54:31] <_abc_> Also Windows is not known to be delicate about filling ram
[10:54:48] <_abc_> I think 1G but can be less. Did not look last time, just marked it down as a 'to do' item.
[10:54:57] <_abc_> It will be 512MB to 1G
[10:55:05] <Loetmichel> 1g would be perfectly OK
[10:55:09] <_abc_> So 512 768 or 1G
[10:55:13] <Loetmichel> 512m will work also
[10:55:21] <Loetmichel> less: not so much ;-)
[10:55:27] <_abc_> I think I have swap configured too never looked
[10:55:48] <_abc_> I expect it to slow down or such and maybe get 'stuck' while it swaps but I do not expect missing window decorations and such
[10:56:03] <_abc_> Btw speed is very okay, even with compiz enabled with all bells and whistles animation etc

[10:56:12] <_abc_> It has no hw accel in graphics
[10:56:16] <_abc_> So no complaints there.
[10:56:33] <_abc_> What about the ro mount on 1st insertion of sticks? That is WEIRD?
[10:58:34] <Loetmichel> sounds like the usual mechaninm fopr damageed filesystems
[10:58:51] <Loetmichel> maybe its reading garbage from the sticks the first time

[10:59:46] <Loetmichel> did you check the md5 sums for the iso?
[10:59:54] <_abc_> yes
[10:59:59] <Loetmichel> did you run the "test the cd" feature at booting?
[11:00:01] <_abc_> Also the 2nd time and on it works fine
[11:00:01] -!- miss0r has quit [Quit: Leaving]
[11:00:33] <_abc_> So it is not reading garbage and the hw is okay since the same stick automounts fine on the same machine 5 minutes before and after on another linux version
[11:00:37] <_abc_> And on windows too
[11:00:48] <Loetmichel> (actually i dont know it fhat works booting from thumbdrive)
[11:01:07] <_abc_> I did the test the cd from the cd I think. Long time ago.
[11:01:22] <Loetmichel> try booting from a CD
[11:01:24] <_abc_> This install was done last Summer I think, or before that.
[11:01:54] <Loetmichel> maybe there is some USB driver issue that reads garbage sometimes and corrupts the system?
[11:02:03] <_abc_> Loetmichel: Why? I already know it is only the software. I am looking for opportunities to tweak the software. F.ex. inserting sleeps in the boot scripts to delay the start of copiz in case it causes trouble due to ram contention
[11:02:32] <Loetmichel> begause that SHOULD not happen to a working live CD
[11:02:33] <_abc_> Loetmichel: If it is, then usb subsystem needs updating in lts 10.04 and that is a nono since it may destroy the rtlinux subsystem
[11:02:40] <Loetmichel> so there IS something wrong
[11:02:46] <_abc_> In software... for sure.
[11:03:10] <Loetmichel> nad if you rule out hardware it MUS have to do with the image
[11:03:39] <Loetmichel> and inserting delays here and there may work but cure only the symtoms, not the disease
[11:03:47] <_abc_> Yes, I am aware.
[11:04:07] <Loetmichel> hmmm
[11:04:14] <_abc_> Has anyone compiled rtlinux + linuxcnc for debian here? 2.6 kernels? Any howto which may save me time?
[11:04:23] <Loetmichel> thinking about it: which graphics chip/which cpu in there?
[11:04:24] <_abc_> (this shows I am prepared to move on)
[11:04:42] <_abc_> It's some celeron and the graphics card is onboard generic intel probably
[11:04:47] <Loetmichel> i had some issues with S3 grapic chips once IIRC
[11:04:47] <_abc_> Nothing special
[11:04:58] <_abc_> It is not S3
[11:05:01] <Loetmichel> that wree something similar erratic behaviour
[11:05:29] <Loetmichel> was an idea

[14:32:40] <revo14> https://www.buildyourcnc.com/category/elcombo
[14:33:26] <revo14> for example this web i can read with interfase USB or port parallel
[14:34:13] <_methods> so you purchased the usb interface board?\

[16:53:58] <CaptHindsight> anyone ever work with the closed loop steppers by leadshine and similar? Do they use variable microstepping to adjust for errors in stepping or what do they actually do?
[16:54:35] <IchGuckLive> they only get you the info if a step is lost

[16:55:28] <CaptHindsight> are they just pulling this out of their.... "No loss of steps; no hunting; no overshooting" ?
[16:55:40] -!- revo14 has quit [Ping timeout: 258 seconds]
[16:55:57] <somenewguy> I have no experience, but I assumed they operate more like a BLDC than a stepper?
[16:56:40] <somenewguy> so they are a MUCH more reponsive servo in control logic, but I could be off the mark, i only did some cursory research a while back for a fizzled project
[16:57:22] <CaptHindsight> I'm trying to see what they actually offer vs the marketing fluff
[16:58:19] <IchGuckLive> i did not loose any step after a hard 8hr shift on the plasma at 4800mm/min contouring and 5200mm G0 with the 880A leadshine and a mesa 7i76
[16:58:50] <IchGuckLive> moving at 0.01mm per step
[16:59:04] <IchGuckLive> no on 4 build ident mashines gantry style
[16:59:21] <IchGuckLive> using rack and pinion T10
[16:59:52] <humble_sea_bass> No loss of steps; no hunting; no overshooting = "we use PID"

[17:00:46] <IchGuckLive> humble_sea_bass: PID is near 600Euro per Axis as Step is near 200
[17:01:25] <humble_sea_bass> for the servodrive you mean?
[17:01:40] amnesic_away is now known as amnesic
[17:02:39] <CaptHindsight> does the PID just supervise until there is a difference between commanded position and actual position?
[17:02:40] <IchGuckLive> yes costs are near tribble at same force
[17:03:15] <humble_sea_bass> PID constantly runs on the closed loop
[17:04:28] <humble_sea_bass> so it smoothly applies acceleration/deceleration and direction in order to get it to converge without oscillating (hunting) or over shooting (fucking up royally)
[17:04:30] <CaptHindsight> ok if that is the approach how does it handle distances less than 1 step?
[17:05:31] <CaptHindsight> is that actually what their closed stepper does or are you just describing a servo in general?
[17:05:57] <humble_sea_bass> I wish I were smarter about machine tool control to answer that, but my feeling is that sub step motion is something that the path projector should deal with

[17:06:50] <humble_sea_bass> well the language they use is just big talking for "we use PID" I felt
[17:07:32] <humble_sea_bass> and PID is all software algorith, so once you tune it, you can get good results
[17:08:01] <CaptHindsight> yeah, I mostly use servos
[17:08:36] <CaptHindsight> thats why I was wondering what they are up to with the closed loop stepping http://www.automationtechnologiesinc.com/products-page/hybrid-servo-system/hybrid-servo-drive-kl-5080h

[17:41:49] <kfoltman> so, if I have a motor driving a pulley and the belt has 180 degree contact with the pulley, do I get 50% of the torque, or?
[17:44:41] <Einar1> Depends on the belt etc. but you should have 100% of the torque if you did things right.
[17:45:48] <Einar1> When 180 degrees contact, that means both pulleys are the same diameter, so no torque transformation.

[18:39:51] <Noxz> my steppers also have rotary encoders on them, but the controller deosnt sdupport it (open hardware/software controller, with breakout pins, so it shouldn't take much to get a board made that the controller can talk to for positonal data

[19:15:44] <CaptHindsight> that's big enough for jumbo walnuts
[19:15:49] <XXCoder> how phillic lol
[19:18:03] <SpeedEvil> I've got a bigger vise - but it has more wood.
[19:18:13] <zeeshan> i mainly wanted a bigger vise
[19:18:26] <zeeshan> cause im holding a lot of big manifolds for cars lately
[19:18:40] <zeeshan> and re-threading out holes
[19:18:55] <zeeshan> i was getting tired of c-clamping them to the welding table :P
[19:21:20] <tjtr33> CaptHindsight, that linear slide from Rockford... their claim to fame is machining the extrusions ( all sides at once or sumpthin )

[19:21:44] <XXCoder> what does "aging" do to exrusions?
[19:21:50] <zeeshan> make em stronger
[19:21:54] <zeeshan> the yield strength
[19:22:10] <tjtr33> the stress goes away, relaxes it
[19:22:19] <XXCoder> cool. what does it do in term of physially? warm? chill? acid bath?
[19:22:22] <CaptHindsight> tjtr33: yes, machine all surfaces at one time
[19:22:25] <zeeshan> XXCoder: the proper term is 'percipitation hardening'
[19:22:38] <zeeshan> it changes the grain structure
[19:22:46] <zeeshan> you're letting the grains become finer
[19:22:47] <CaptHindsight> SIMO for simultaneous machining
[19:22:56] <zeeshan> finer grains impede dislocation movement
[19:22:58] <XXCoder> interesting.

[19:25:46] <CaptHindsight> XXCoder: we should probably post them all somewhere since people ask the same questions all the time and the videos give them the skills to solve them
[19:25:54] <zeeshan> (if its age hardenend, aluminum is at its peak strength)
[19:25:59] <tjtr33> no thanks i hate salesmen, spent my life making machines do what a salesman said it would.
[19:26:01] <zeeshan> but after 20 years or so
[19:26:10] <CaptHindsight> heh
[19:26:11] <XXCoder> what about linuxcnc channel FAQ wiki? lol
[19:26:11] <zeeshan> it loses almost 35% of its yield strength
[19:26:14] <tjtr33> despite what mfctr said
[19:26:57] <tjtr33> " veditori??? spah! pirata! "
[19:27:00] <XXCoder> zee well everything ages. some well some not so well. I remember this machine at boeing. it was over 100 years old. very big machine. tour guy said it always worked
[19:27:08] <zeeshan> not steel
[19:27:13] <zeeshan> alumninum will
[19:27:22] <CaptHindsight> embellished specifications!? I'm shocked totally shocked
[19:27:38] <XXCoder> and theres 7 year old machine thats set in its own room because its riciously sensive and will break down once a while. both has same tasks.
[19:27:45] <CaptHindsight> http://www.youtube.com/watch?v=nM_A4Skusro
[19:27:51] <XXCoder> stell ages too but I think those just harden

[19:28:14] <zeeshan> theres on in the book
[19:28:30] <zeeshan> but it looks similar to that for 2024 aluminum
[19:28:46] <zeeshan> ugh
[19:28:47] <zeeshan> thats not it
[19:28:53] <zeeshan> thats a stress vs strain
[19:29:00] <zeeshan> its a yield strength vs time
[19:30:05] <zeeshan> i guess hardeness vs time would show the same strength
[19:30:18] <zeeshan> same trend not same strength

[19:39:03] <zeeshan> on its mechanical properties inst too significant
[19:39:22] <zeeshan> range of +/- 10MPa effect
[19:39:50] <zeeshan> +/- 1450 psi
[19:40:23] * SpeedEvil ponders casting iron.
[19:40:55] <MrHindsight> cast epoxy composites
[19:41:19] <MrHindsight> but then you need a flat surface to cast on

[19:41:53] <SpeedEvil> (pretty close anyway)

[20:15:00] <SpeedEvil> I have real problems imagining they're going to be anywhere near as cheap as normal ones.
[20:16:08] <Jymmm> one of these http://i61.tinypic.com/2qi2uc9.jpg

[20:16:28] <Jymmm> not solar panels
[20:16:51] <MrHindsight> the indegogo 7" panel is $7k
[20:17:00] <SpeedEvil> If you want to do that - it's going to be vastly cheaper to stick solar panels on 'light poles' - and then laser project lights onto the ground
[20:17:02] <MrHindsight> sorry $10k
[20:17:11] <Jymmm> MrHindsight: 7" across?

[20:21:33] <SpeedEvil> It's ideal for a parking lot for a buisness.
[20:21:45] <SpeedEvil> For roads - not really
[20:21:51] <Jymmm> Love the disclaimer at the bottom... http://www.equities.com/editors-desk/stocks/technology/why-the-solar-roadways-project-on-indiegogo-is-actually-really-silly
[20:22:38] <Jymmm> Roads in problem areas it be great
[20:23:16] <SpeedEvil> As a ballpark, in mass quantities, the components are of the order of 60 dollars.
[20:23:32] <Jymmm> If a car was broken down in the left lane, the LEDs could merge traffic by reshaping the lanes as needed
[20:23:55] <Jymmm> $60 a hex?
[20:24:09] <Jymmm> I think they are 2ft apx
[20:24:21] <CaptHindsight> This is a Way to Fund This Couple's Hobby
[20:24:24] <SpeedEvil> yes.
[20:24:49] <Jymmm> so $2400 for one lane
[20:25:00] <CaptHindsight> " I’m guessing, is why the question of cost doesn’t come up at any point in either the IndieGoGo video OR the couple’s website. It’s why their idea doesn’t actually make any sense."
[20:25:01] <Jymmm> 10ft lane x 2ft
[20:25:07] <tjtr33> Jymmm, thx for 'solar frkn roadways'
[20:25:28] <Jymmm> so $1200 a foot per lane
[20:25:47] <CaptHindsight> why not just solar hats? power anything close to your head
[20:26:20] <Jymmm> How much is a foot of lane cost now?
[20:26:47] <CaptHindsight> http://sroeco.com/solar/images/PVeff-rev100414.png
[20:28:02] <Jymmm> http://wiki.answers.com/Q/How_much_does_it_cost_to_build_a_paved_road
[20:28:26] <Jymmm> $64 to repave
[20:29:02] -!- toner [toner!~ink@c-71-198-91-97.hsd1.ca.comcast.net] has joined #linuxcnc
[20:29:03] <tjtr33> so in illinois thats 64/ft/year ;)
[20:29:22] <Jymmm> that's not even a new road, that's just to repave
[20:29:28] <CaptHindsight> heh
[20:30:22] <Jymmm> and they would be revenue generating as well
[20:32:05] <Jymmm> So lets say a 2ft hex solar road is the equiv of a 50W solar panel
[20:32:47] <Jymmm> so that would be 250W per foot of one lane of road
[20:33:52] <CaptHindsight> Sunpower offers a 230 Watt solar panel rated at 18.5% efficiency. Its surface area is 13.4 square feet.
[20:34:17] <CaptHindsight> http://solarroadways.com/numbers.shtml use their numbers with any panel you wish
[20:34:34] <Jymmm> 250W * 5280ft (1 mile) = 1.3MW * 15% efficieny = 198KW per mile, per lane

[20:35:52] <FrankZappa> ohgod, the solar road people
[20:35:59] <FrankZappa> so dumb
[20:36:01] <CaptHindsight> you might get a few years out of those panels under ideal conditions
[20:36:50] <FrankZappa> nobody should be taking that project seriously.
[20:37:01] <FrankZappa> The fact that the US Govt has given this guy any money is sad.
[20:37:24] <FrankZappa> It's like they don't have anyone with an engineering background connected to any sort of innovative engineering payouts.
[20:37:56] <SpeedEvil> It depends.
[20:38:02] <FrankZappa> You're not going to get the same irradiance
[20:38:05] <SpeedEvil> As a whole road surface, it's clearly insane.
[20:38:20] <SpeedEvil> As a controllable driver signalling one - it may not be.
[20:38:22] <FrankZappa> as any kind of duty surface, it's clearly insane.
[20:38:28] <zeeshan> i personally think you can fix the problem w/ it with it easily
[20:38:35] <zeeshan> instead of putting it on rods
[20:38:40] <zeeshan> *roads, you put em on side walks
[20:38:48] <CaptHindsight> Germany has already shown what works and what doesn't work well
[20:38:49] <FrankZappa> also a terrible idea
[20:38:50] <zeeshan> so they won't see as much load
[20:38:56] <FrankZappa> put solar panels where they will get SUN
[20:38:57] <SpeedEvil> Put them on roofs.
[20:39:00] <Jymmm> FrankZappa: WHY is is a bad idea?
[20:39:02] <zeeshan> FrankZappa: you're a terrible idea
[20:39:03] <FrankZappa> It's not like we have a lack of PLACES for solar panels
[20:39:05] <zeeshan> in generally
[20:39:11] <FrankZappa> Why put them under roads?
[20:39:13] <zeeshan> FrankZappa: you tard
[20:39:16] <SpeedEvil> Roofs (can be) optimally sloped for solar panels.
[20:39:18] <FrankZappa> Literally the worst place to put them
[20:39:23] <zeeshan> the whole idea is to make revenue when you build infastructure
[20:39:27] <FrankZappa> tard?
[20:39:29] <SpeedEvil> And people may actually pay you to put them on a roof
[20:39:30] <zeeshan> not just put them in the middle of unused land
[20:39:31] <FrankZappa> what channel am I in?
[20:39:40] <zeeshan> yes, mr. terrible idea.
[20:39:40] <SpeedEvil> Done right.
[20:39:43] <CaptHindsight> on kites high above the clods
[20:39:57] <CaptHindsight> the string is also the power cord
[20:39:57] <Jymmm> I road generating revenue to pay for itself is not a bad idea.
[20:40:04] <zeeshan> Jymmm: i agree
[20:40:10] <zeeshan> and it's pretty ignorant to call it 'terrible'
[20:40:15] <FrankZappa> Jymmm ever heard of tolls?
[20:40:25] <pcw_home> which clods are you referring to?
[20:40:31] <SpeedEvil> The economics don't work.
[20:40:42] <SpeedEvil> It is vastly cheaper to do a dumb road, and a solar farm
[20:40:46] <Jymmm> FrankZappa: That's not generating revenue, that's charging a tax on top of the tax you already paid.
[20:40:52] <zeeshan> people shoot down ideas in this modern age like they're nothing
[20:40:55] <FrankZappa> Jymmm no, it's not.
[20:41:06] <zeeshan> thats why most projects with some possibility of working die before they even start
[20:41:07] <Einar1> Are those roads controlled by LinuxCNC?
[20:41:10] <zeeshan> welcome to FrankZappa
[20:41:16] <zeeshan> Einar1: they better be!!! :D
[20:41:18] <FrankZappa> I'm not going to argue about your lack of proper set categorization
[20:41:20] <CaptHindsight> all you have to do is run the numbers
[20:41:23] <Jymmm> If a road just sitting there is generating it's own money
[20:41:28] <FrankZappa> the fact remains that putting solar panels under roads is retarded
[20:41:39] <CaptHindsight> but the roadway solar project doesn't have the numbers
[20:42:15] <Jymmm> FrankZappa: You have nothing to back that up, all you've said is "it's stupid" just ike a 9yo kid would, back your shit up at least, give a valid argument
[20:42:30] <FrankZappa> It's hilarious, almost as if someone said, "Hey, solar power is starting to become more viable. How about we dampen that with a bunch of really expensive, inefficient locations for them?"
[20:42:31] <zeeshan> the roads also make sense for busy downtown cores.

[22:01:26] <malcom2073> Supercapacitors are fairly awesome
[22:02:33] <malcom2073> I would not have thought that 330F would be enough to start a car, but that goes to show how much I actually know about energy :)
[22:10:32] <Jymmm> malcom2073: the blue or black ones?
[22:10:47] <malcom2073> The blue
[22:11:07] <Jymmm> malcom2073: the black ones are pretty cool too
[22:11:30] <Jymmm> malcom2073: But that you can INSTANTLY charge up teh blue ones from a solar panel is cool
[22:11:31] <malcom2073> They were, I liked the form factor, he said like 2.6kF or something?

[22:20:00] <malcom2073> Ah heh, so prices skyrocketed when demand went up I guess?
[22:22:01] <Jymmm> I think someone misidentified what they were =)
[22:22:29] <Jymmm> maybe they thught it was a typo.... 1200uF instead of 1200F =)
[22:26:11] <Jymmm> malcom2073: It be cool if there was a research center where cost/price wasn't a factor. Not outragious things like a 24 caret dimaond heatsink, but realistic things like a 1,000,000 mile tire (goodyear has the patent on that)
[22:26:42] <malcom2073> Heh
[22:27:14] <Jymmm> or a car that does 120MPG, that was done back in the 80's

[22:40:49] <mozmck> i see.
[22:41:25] <mozmck> EPA's idiot rules make the fuel economy stay down.
[22:41:53] <FrankZappa> Howso?
[22:42:24] <mozmck> How so? Well, it is the EPA that won't let all the 60 to 75+ mpg diesel cars in the US.

[22:44:20] <FrankZappa> Whats your source?
[22:44:26] <mozmck> not just antiqued, but I think intentionally stupid. If you burn half as much fuel, you put out less pollution by default than a car burning twice as much.
[22:44:43] <mozmck> source for what? the cars available in the EU?
[22:45:01] <XXCoder> even if double pollution high mog means still lower pollution
[22:45:07] <mozmck> or the EPA rules stopping them from coming over?
[22:45:48] <mozmck> I have read many articles, websites, and talked to people who have tried to even bring one car over.
[22:46:11] <FrankZappa> So whats your EPA leg source?
[22:46:15] <FrankZappa> Which reg needs changing?
[22:47:47] <FrankZappa> Clean Air Act?
[22:47:53] <mozmck> I haven't looked at the regs myself - too many of them and no time here.
[22:48:13] <FrankZappa> Did you ever consider the diesel in Germany for auto use isn't the same as whatever is legally called "diesel" in the US?
[22:48:24] <FrankZappa> So, you are just hand waving then, I guess
[22:49:37] <zq> zultron: yes i have. i'll be creating some pull requests tonight.
[22:49:57] <FrankZappa> Maybe these cars need pollution to be so efficient
[22:50:04] <FrankZappa> lead does help engines quite a lot
[22:50:10] <zq> is it normal to have 60% constnat usage by the rtapi process?

[22:52:09] <FrankZappa> http://www.scientificamerican.com/article/why-european-diesel-cars/
[22:52:34] <FrankZappa> well, your bias has been established :)
[22:53:03] <malcom2073> As has the article writers :)
[22:53:25] <FrankZappa> you hate cyclists, therefore anything he has to say is invalid.
[22:53:46] <FrankZappa> That's precisely one cause of ignorance
[22:53:49] -!- jduhls has quit [Ping timeout: 240 seconds]
[22:54:11] <malcom2073> I don't hate cyclists
[22:54:18] <FrankZappa> And it tells me you have no interest in dialogue on the subject. You allow agreement, or jousting.
[22:54:18] <malcom2073> I hate cyclists that use that as an excuse to hate diesels
[22:54:25] <mozmck> That's exactly what that cyclist does, he hates diesels so therefore the government should ban then.
[22:54:32] <malcom2073> The second article however seems more valid
[22:55:00] <FrankZappa> ... because it doesn't mention the problems with diesel in the US.
[22:55:07] <zeeshan> woohoo
[22:55:11] <zeeshan> won a bunch of dial indicators
[22:55:19] <FrankZappa> My final advice to you is, beware oversimplification

[22:55:24] <zeeshan> so many indicators
[22:58:31] <mozmck> I would say that you should beware emotional arguments devoid of good science and facts. I could have missed some studies, but I have not seen any actual studies showing drastically higher incidents of cancer and all in diesel mechanics than anyone else. If diesel exhaust is as bad as some try to say, it would show up in diesel mechanics first and be *well* known, because they live in diesel exhaust.
[22:58:40] <FrankZappa> Good science and facts?
[22:58:57] <FrankZappa> What "facts" does your argument possess?
[22:59:22] <FrankZappa> And who are the sources of these facts?
[23:00:24] <FrankZappa> Are they, by any chance, the same guy who said a passenger on MH370 smuggled his iphone up his rectum, and sent him a picture from a secret US airstrip?
