[06:24:09] <jesseg> Sorry Mac, I have no experience with mesa at all.
[06:24:21] <jesseg> I thought it was a video graphics driver from the dos days :P
[06:24:36] <jesseg> Or was it an FPGA project too? Somehow that has a familiar ring
[06:26:06] <MacGalempsy> maybe a general linux question?
[06:26:15] <jesseg> sure
[06:26:21] <MacGalempsy> when I install the card, the machine will not boot
[06:26:24] <jesseg> linux I do (mostly slackware)
[06:26:41] <jesseg> What distro? What sort of computer?
[06:26:56] <MacGalempsy> it is a ibm m57 sff pc
[06:27:16] <MacGalempsy> the latency test ran great, so I was excited
[06:27:17] <jesseg> Is that a laptop?
[06:27:24] <MacGalempsy> no a desktop
[06:27:32] <jesseg> oh, so it's a regular computer
[06:27:37] <jesseg> ohh - the "card" is the mesa card?
[06:27:45] * jesseg <- not a mesa guy
[06:27:59] <MacGalempsy> yesx
[06:28:05] * jesseg googles mesa cnc
[06:28:14] <MacGalempsy> their support is crap
[06:28:23] <MacGalempsy> online, however, I could call
[06:28:26] <jesseg> Is it a stepper or a servo motor controller?
[06:28:41] <MacGalempsy> servo daughter card
[06:28:53] <jesseg> like a PCI card?
[06:28:58] <MacGalempsy> the daughter card is a 7i77 but it is not hooked up yet
[06:29:12] <jesseg> okay I'm getting the picture - but how does the PC interface to mesa?
[06:29:19] <MacGalempsy> pci card
[06:29:57] <jesseg> http://www.mesanet.com/graphics/parallel/7i76pandgcolo.png
[06:29:59] <jesseg> like that?
[06:31:04] <jesseg> So to clarify, if the PCI card is inserted, then no boot. Otherwise, happy boot (except LinuxCNC is mad about not finding any hardware.)
[06:32:05] <MacGalempsy> yep. you think I need to have the cable hooked up?
[06:32:20] <MacGalempsy> the jumpers are set for no daughter card at the moment
[06:32:40] <jesseg> Not sure if cable makes a difference. Try it if easy. But when you say it won't boot -- how far does it start to boot?
[06:32:47] <jesseg> Do you see the POST messages (ram test, etc.)
[06:33:37] <MacGalempsy> I dont see the post msgs
[06:33:55] <jesseg> And no beeping?
[06:34:00] <jesseg> Does the monitor come out of sleep?
[06:34:28] <MacGalempsy> it comes on, then shuts off, then it powers on but just the fan runs
[06:34:39] <MacGalempsy> the monitor does not come out of sleep
[06:35:11] <jesseg> Have you let it sit for 15 minutes just to make sure it won't time out and throw an error? Can help in debugging

[06:38:58] <MacGalempsy> there is nothing in the bios that says the port is shut down

[06:40:31] <jesseg> I'm wondering if the mesa card has corrupted code on it that is causing it to assert lines on the PCI buss that is halting the computer
[06:40:42] <jesseg> Try mesa card in another computer, or another slot in same computer
[06:43:56] <MacGalempsy> only one slot. in the computer
[06:44:19] <jesseg> Hmm. well I'd try same mesa card in another computer, and try some other card in questionable slot
[06:44:20] <MacGalempsy> I have a newer alienware that it will fit in
[06:45:32] <jesseg> You might also go into bios on troublesome computer and restore to defaults.. Maybe something's strange set that doesn't work with mesa card
[06:45:40] <jesseg> seems unlikely but it's free to try :P
[06:47:08] <jesseg> Is there a way to reset the mesa card back to factory defaults? (Or is it ram based, needing its code to be loaded on each bootup?)
[06:47:35] <jesseg> well that's all the ideas I have. I'm going to wonder off for a bit, then check back, then go to bed, Lord willing.

[07:09:45] <jesseg> MacGalempsy, OK... strange..
[07:10:22] <jesseg> However, if the "bad" machine doesn't even do the power on self test (POST) then I highly doubt that it has anything to do with Linux or the operating system or software.
[07:10:54] <MacGalempsy> I think i saw a post setting in the firmware
[07:10:57] <MacGalempsy> or bios
[07:11:08] <MacGalempsy> let me check for it again
[07:11:11] <jesseg> You can get LinuxCNC on a self booting "LIVE" cd. And you can use it that way by putting in a thumb drive - all modifications you make to programs and stuff get saved to the thumb drive
[07:11:17] <jesseg> Oh, yeah, maybe POST is turned off.
[07:11:37] <jesseg> or post display. post always happens, but the display of it can be turned off.
[07:11:52] <jesseg> But, it would wake up the monitor and display a logo if it was doing post
[07:12:02] <jesseg> Hmm
[07:12:30] <jesseg> Try unplugging the hard drive cable for the linux computer, and try booting it with the mesa card in, and see if it gives you a disk not found error
[07:12:39] * jesseg wonders off again, will check back in a few
[07:13:53] <MacGalempsy> it is set to quick
[07:14:05] <MacGalempsy> perhaps I need to change that
[07:14:11] <MacGalempsy> to enhanced?
[07:14:50] <MacGalempsy> ok. have to shut this machine down to take out the card.

[07:21:51] <MacGalempsy> crap that did not work either
[07:22:21] <MacGalempsy> letting it run for a bit to see if an error bar shows up. but the green power light doesnt work
[07:23:00] <MacGalempsy> do you think it needs a driver in linux before it will power up?
[07:24:25] <MacGalempsy> I wonder if the 280w psu is too small
[07:27:05] <jesseg> back
[07:27:24] <jesseg> no, it doesn't need a driver to power up.
[07:27:46] <jesseg> The driver would be stored on the hard drive, and the hard drive isn't read until after it powers up, so a driver on the disk can't help it power up
[07:27:58] <jesseg> It may be an incompatibility with Mesa and a cheap mobo?
[07:28:23] <MacGalempsy> andypugh thought this one would work
[07:28:30] <MacGalempsy> so I got it, dang...
[07:28:43] <MacGalempsy> its an IBM m57 sff computer
[07:29:07] <jesseg> I don't know andypugh..
[07:29:33] <jesseg> I don't know what to say. You could try taking all other cards out of the m57 to see if maybe the mesa is conflicting with those.
[07:29:56] <jesseg> You might also try disabling all onboard peripherals in the bios other than video just to see if that's an issue
[07:30:02] * jesseg wanders away
[07:32:35] <Jymmm> MacGalempsy: do you have a larger PS to test with?

[07:41:10] <t12> just read back
[07:41:18] <_DJ_> morning
[07:41:21] <t12> lenovo/ibm machines were sometimes particular about the pci cards in them
[07:41:24] <t12> on purpose
[07:41:27] <t12> notably on laptops
[07:41:34] <MacGalempsy> crap. anyway around that?
[07:41:36] <t12> like theres a bios whitelist of allowed PCI ids
[07:41:46] <t12> i dont know if that extended to the desktop machines though
[07:41:56] <t12> there were, modifications to the bios
[07:41:58] <t12> it doesnt post at all?
[07:42:04] <t12> like doesnt even start to?
[07:42:05] <Jymmm> MacGalempsy: Stop guessing.
[07:42:29] <Jymmm> t12 isn't helping atm, as he hasn't read back.
[07:42:50] <Jymmm> MacGalempsy: Again, why were you mucking with the video source?
[07:43:18] <Jymmm> MacGalempsy: And do you have a larger PS to test?
[07:43:21] <MacGalempsy> i changed the video from automatic to internal because there is auto. internal. PCI and PCIE. I thought the machine may be trying to load the card as video
[07:43:39] <MacGalempsy> yes I have a few different psu
[07:43:46] <Jymmm> how big?
[07:44:09] <Jymmm> 400W? 600W ?
[07:44:30] <t12> any ebeps
[07:44:31] <t12> beeps
[07:45:00] <Jymmm> t12: Dude, read back before going over the same things
[07:47:38] <MacGalempsy> no bigger psu that I can put in this computer. the t7500 that I it booted up on is 1100w
[07:47:52] <MacGalempsy> the other psu are 100, 150w...
[07:48:21] <Jymmm> MacGalempsy: You booted it form a 1100W PS and still have the issue?
[07:48:30] <Jymmm> MacGalempsy: Not install, JUST test.
[07:48:40] <Jymmm> from*
[07:49:11] <MacGalempsy> I put the card into my workstation with win7 and the machine booted and recognized the card
[07:49:22] <Jymmm> I didn't ask that.
[07:49:30] <MacGalempsy> i put the card back into the linux box and it didnt work
[07:49:43] <MacGalempsy> the win 7 machine is 1100w psu
[07:50:04] <MacGalempsy> i cannot pull the psu from the workstation, it is too big
[07:50:21] <Jymmm> the cable isn't
[07:50:42] <Jymmm> unplug it from the mobo, and plug it into the ibm

[07:59:49] <t12> the netbook? i dont think so
[08:00:03] <archivist> t12 not got the manual for mine yet
http://www.collection.archivist.info/archive/DJCTM/EQ/2009_01_01_a/IMG_9999.JPG
[08:00:09] <Jymmm> ah ok, mine does so I use a REAL UART serial port
[08:00:42] <t12> remote X11 mode on the 16500's is awesome too
[08:00:48] <t12> though i think the 16500a doesnt have eth?
[08:01:01] <archivist> not that I remember
[08:01:26] <archivist> I need a gpib card one day
[08:01:26] <t12> yeah i'm stuck with all usb things on it
[08:01:47] <t12> that was just a junk pile meachine that was the easiest xp install i could get my hands on
[08:02:11] <Jymmm> archivist: Want the service manual for it?
[08:02:50] <t12> i have a 16500B with a mess of timing/state cards in it
[08:02:54] <t12> that i need to get rid of
[08:03:12] <t12> they're pretty annoying to transport
[08:03:14] <archivist> I think there are some changes A to B
[08:03:20] <Jymmm> archivist: 144 pages
[08:03:28] <t12> C's take ps2 kb/mouse and have stock wth i think
[08:03:35] <t12> s/wth/eth
[08:04:08] <Jymmm> archivist: Confirmed it's from HP 16500A Service Manual
[08:04:13] <t12> i piled up all this LA gear and then rarely use it
[08:04:25] <t12> sort of absurd to use a 16700 to record 1 pin
[08:04:41] <archivist> Jymmm, paper or pdf ?
[08:04:45] <Jymmm> archivist: pdf

[08:05:08] <Jymmm> archivist: Not a scan either, the real thing
[08:06:06] <archivist> what do you mean not a scan, HP went to microfiche and then scanned them for some manuals
[08:06:15] <Jymmm> archivist: Reference Manual

[08:06:45] * archivist starts another download
[08:06:51] <Jymmm> archivist: you want a scrn cap?
[08:07:20] <archivist> for what, same device?
[08:08:05] <jesseg> back
[08:08:14] <archivist> my mirror directory has expanded by two :)
[08:08:38] <Jymmm> archivist: lol, thought you might like those =)
[08:09:09] <t12> amazingly for the 16700's theres some web form

[08:10:42] <Jymmm> archivist: I know you have limited bandwidth. I was offering a SCRN CAP(screen capture) of the first page of the pdf
[08:11:02] <archivist> HP and TEK dont mind too much about mirrors of their manuals in the wild
[08:11:05] <jesseg> hi MacGalempsy. How's it going?
[08:11:10] <MacGalempsy> well, I didnt to it because it was too much to unplug all the wires
[08:11:20] <jesseg> do what?
[08:11:31] <jesseg> oh the PSU
[08:11:35] <MacGalempsy> the psu on the big box is too much hassle to get out for this test
[08:11:45] <archivist> Jymmm, I am not limited download, I have already got both manuals downloaded thanks
[08:12:13] <Jymmm> archivist: Ah, ok. np. I know you collect all that stuff
[08:12:29] <MacGalempsy> so I need to find a system that is known to work with the mesa 5i25
[08:12:32] <archivist> yes a bit of a manual packrat
[08:12:54] <MacGalempsy> luckily this m57 was only $80
[08:12:55] <Jymmm> archivist: and building your library collection iirc
[08:13:15] <MacGalempsy> well, I will go back to the wiring diagram
[08:13:53] <MacGalempsy> if anyone is interested, I have it up in hangout
http://tinyurl.com/o5rk3w9
[08:14:06] <archivist> Jymmm, qties are on
http://www.collection.archivist.info/
[08:14:44] <jesseg> MacGalempsy, It's probably not a PSU problem. Unless it's a real muscle machine, 250W ought to be plenty to boot up with one PCI card and one hard drive. I have an AMD 8 core 3.6Ghz system with 16G of ram and TWO 2TB hard drives and extra fans, and it idles at 64 watts INPUT to the power supply.
[08:15:16] <archivist> the startup may need more power
[08:15:18] <MacGalempsy> i figured the psu is ok because its beefier than those in my other pcs
[08:15:41] <jesseg> MacGalempsy, what CPU? 2 core? 32 core?
[08:15:49] <MacGalempsy> duo core
[08:15:53] <jesseg> how fast?
[08:16:06] <MacGalempsy> let me look it up
[08:16:40] <Jymmm> archivist: I just wish you included auto service manuals too =)
[08:16:40] <MacGalempsy> 2.33ghz
[08:17:10] <archivist> Jymmm, I do
[08:17:32] <Jymmm> archivist: 1988 Honda Civic LX ?
[08:17:38] <archivist> nope
[08:17:43] <Jymmm> damn
[08:17:45] <Jymmm> lol
[08:18:09] <jesseg> MacGalempsy, yeah I really don't see how 250W can't be enough. If you have another PSU lying around you could try it, but I'm going to suggest that its an incompatibility with mobo and fpga card
[08:18:16] <archivist> Jymmm, search lucas, a parts maker in my search box
[08:19:15] <MacGalempsy> i agree. there have been other issues with lenovo mobos, so perhaps I have to chalk this one up to trial and error
[08:19:29] <Jymmm> archivist: LOL. Any Honda or Ford?
[08:19:46] <archivist> type the name in the search box
[08:20:19] <archivist> remember I am in the uk so usually not usa models
[08:21:40] <Jymmm> archivist: I understand, but I dont think you care where you get them from either way
[08:21:53] <Jymmm> UK/US/AU/whatever
[08:22:34] <Jymmm> archivist: I'll get you a PDF of FORD you can add to your collection sometime
[08:23:14] <archivist> I generally get real paper manuals, currently stuff I have on PDF is not in the collection proper
[08:23:43] <Jymmm> archivist: I'm not giving up my paper wiring diagram manual just yet =)
[08:24:40] <Jymmm> archivist: I might be buying a civic tomorrow if all works out.

[14:26:46] <Sven___> If tooltrigger is a button?
[14:27:35] <Sven___> It is a hal pin going high/low when a tool position is passing by when the tool changer is rotating.
[14:35:20] <kwallace> Sven___: I think I'm way off base. I need to rethink your question, somehow I fixed on Glade.
[14:36:05] <Sven___> Sorry, no glade. It is a user space component loaded with hal.

[21:26:26] <pcw_home> Unlike the Fanuc interface, It appears to be just a standard UART
[21:27:25] <pcw_home> (probably allowed them to use normal UCs for both ends)
[21:28:14] <pcw_home> 9x 8 bit chars each char with a single start and stop bit
[21:29:46] <pcw_home> for the best Mesa interface, I would need to add autosend to our UART (and an option to autosend on timerx)
[21:30:28] <pcw_home> (so the request can be sent automatically)
[21:35:00] <pcw_home> Probably a good thing, thinking about this, I could add autosend with just a FF or two and a FIFO pointer latch
[21:35:02] <pcw_home> (this should also work for SPI) I was considering an alternate xmit buffer but by latching. restoring the FIFO pointers
[21:35:03] <pcw_home> I can re-use the standard xmit buffer for autosend
[21:39:32] <t12> i'm suprised this is actually panning out!

[22:05:41] <pcw_home> the 01s are stop/starts
[22:06:05] <pcw_home> so just a UART
[22:06:32] <alex_joni> whee.. ascii art ;)
[22:07:05] <t12> ahh i see
[22:07:09] <t12> i decoded right through the stops i guess
[22:07:23] <t12> but i guess that just becomes a fixed shift and offset in the computed number
[22:08:24] <t12> its a 17bit encoder so the position might fall over into that EF byte
[22:08:36] <t12> i think they make 18s too
[22:09:12] <pcw_home> I presume its MSB first
[22:09:22] <t12> i only have 4MB of LA buffer and oersampled alot
[22:09:28] <t12> so i may not have covered a full rotation
[22:10:08] <pcw_home> in any case the Mesa UART should work fine +- some autosend patches for best performance
[22:10:32] <pcw_home> (and low jitter request pulse send)
[22:10:37] <t12> i think LSB first
[22:10:45] <t12> the earlier bits flip more
[22:10:54] <pcw_home> OK
[22:11:01] <t12> http://dodeca-t.com/output.txt
[22:12:43] <pcw_home> in any case, looks pretty simple. I got a Yaskawa drive to try with the 2 wire
[22:12:44] <pcw_home> Yaskawa encoder so I will mess with that next week, it may be similar
[22:13:19] <t12> yeah theres only so many ways to send the data
[22:13:58] <pcw_home> I guess theres Matshushta as well
[22:14:23] <pcw_home> and Okuma
[22:14:33] <t12> any idea of te rank order popularity of these various motors?
[22:14:56] <pcw_home> though Okuma may well be parallel/ multiple bytes
[22:15:16] <pcw_home> no Idea though Fanuc seems the most common
[22:15:19] <t12> theres a lot of pins on their encoder connector
[22:15:52] <pcw_home> Yeah but not enough for full parallel so it may be muxed bytes or some such
[22:16:44] <t12> ok lunch time
[22:16:46] <pcw_home> they tend to be expensive (Okuma absolute encoders) So I haven't snagged one yet
[22:17:26] <pcw_home> do you know what the request pulse is?

[22:54:03] <s1dev> is it significant?

[22:54:54] <s1dev> 3'ish
[22:57:20] <andypugh> eBay is great for linking folk happy to buy the 3m bars, cut them and post. But that is their business. If you actually want a 3m length, then go to a stockholder (who only sell 3m lengths). If you want more than 10 x 3m lengths, then you need to be talking to the forge direct.
[22:57:35] <andypugh> 3' is awkwardly in the middle.

[23:16:33] <Valen> my way works with 2 people
[23:16:57] <Valen> the clean fluid comes from the resivour, the jar is there so when it sucks back it doesn't suck air
[23:17:20] <Valen> I suggest getting a brake bleeder kit, they are like $10 and have a little one way valve in them
[23:17:28] <Jymmm> Valen: Right, but it spit out dirty fluid into the jar
[23:17:43] <Tom_itx> keep spitting until it's clean

[23:27:54] <andypugh> A friend bought it off us. He worked out that the brake servo was a tractor part. But had been fitted by Landrover, the vehicle serial number was 3.
[23:29:09] <andypugh> I think he got it all working by ignoring the bleed sequence in the manual (using a bleed nipple that was on the servo, but shouldn't have been there)
[23:29:21] <Jymmm> I forget, can you use tranny fluid instead of PS fluid?
[23:30:10] <Tom_itx> if i were in the middle of nowhere and that's all i had i would
[23:30:26] <Tom_itx> you're going to the AP store anyway
[23:31:16] <Jymmm> Yeah, was just curious. They say you could on older 1970's cars

[23:33:32] <andypugh> In Cuba apparetly they use Shampoo.
[23:33:50] <Jymmm> good to know =)
[23:34:05] <Jymmm> But all the cars are 1950's American
[23:34:13] <andypugh> (which is largely silicone oil, which I think they have figured out how to purify out)
[23:34:32] <andypugh> Yeah, mainly because you are really rather mean to them.

[23:35:23] <jdh> gotta keep them damned commies in line.
[23:36:02] <jdh> my daughter is trying to convince us to send her to Cuba for a semester to 'study'

[23:36:41] <andypugh> Actually, no, you don't (though I suspect you have your tongue firmly in your cheek there)
[23:37:14] -!- micges has quit [Quit: Leaving]
[23:37:27] <andypugh> And, havung typed it, what the heck does "tongue in your cheek" mean? what a strange phrase
[23:37:35] <jdh> I'm amazed by the number of my fellow americans who think 'nobody' is allowed to travel to cuba.
[23:37:46] <jdh> vs. just us
[23:38:17] <andypugh> If she _can_ go then I think she would get a lot out of it, to be honest.
[23:38:56] <jdh> the only thing that would prevent her from going is my willingness to pay.
[23:39:26] <andypugh> http://youtu.be/qL0IItt-ff8
[23:42:25] <jdh> not going in my vehicles.

[23:46:10] <andypugh> I suspect it isn't their first choice.
[23:47:38] <andypugh> Brake fluid is either silicone oil (and shampoo is generally silicone oil, dimethicone) or glycol-ester. I don't know what sugar + alchohol makes (other than a good party)
[23:48:59] <jdh> speaking of materials...
[23:49:26] <jdh> is there anything you can use as a cover gas for TIG welding zirconium other than argon and helium?
[23:50:13] <DaViruz> probably most noble gases?
[23:50:42] <DaViruz> i doubt there'd be any advantages over argon though..
[23:50:53] <jdh> certainly not cost.

[23:51:57] <Valen> lol wow he is young there
[23:53:02] <Valen> sugar probably wouldn't do such a good job in a "performance" application
[23:53:23] <Valen> the sugar would caramelise
[23:54:03] <Valen> actually the shampoo is mostly water, so that seems like a bad plan
[23:56:47] <jdh> wiki says DOT2 is castor oil + alcohol
[23:57:10] <Valen> half the power steering stuff still had whale oil in it into the 1970s

[23:59:52] <Tom_itx> you could tell too, it stinks
[23:59:54] <andypugh> Valen: Not that much water in some shampoos.
