[00:20:25] <Guest3351> hmm for locking the bearing nut on a ballscrew .. is red loctite to be recomended? =) i guess i will not remove the nut until i need to change the bearing ... :P
[00:20:48] <Guest3351> the little set screw on the side is to wimpy to hold it in place and it works itself loose :/
[00:27:59] <CaptHindsight> red might work, it has the highest adhesion available in an anaerobic from Henkel
[00:47:03] <MrSunshine> mm was thinking red but then i will ahve to heat it if i need to remove it for some reason ? i should never need to until the bearing is shot like i said but =)
[00:47:54] <MrSunshine> kinda annoying when parts starts to get ***ed up and you notice the screw moves like 1mm back and forth when the machine turns :P
[03:15:29] <Deejay> moin
[08:05:58] <R2E4> I have 2.5, do I need to go to w.5.1?
[08:06:03] <R2E4> 2.5.1
[08:08:44] <R2E4> It says to see below on rebranding changes for 2.5.1, but it doesnt show anything.
[08:47:13] <jthornton> 2.5.3 is current
[08:56:44] <Jymmm> jthornton: Are speakon connectors suppose to be waterproof that you know of?
[08:58:11] <jasen> no its not
[08:59:39] <Jymmm> jasen: thanks
[09:10:04] <jthornton> speakon?
[09:16:04] <jasen> yea , commonly used for stepping motor connectors.
[10:38:10] <JT-Shop> the white plastic square connectors?
[10:40:07] <CaptHindsight> http://www.neutrik.com/en/speakon/ he might mean these
[10:41:18] <Tom_itx> if it were stepper he would be looking for at least 4 wire
[10:42:52] <CaptHindsight> http://www.neutrik.com/en/speakon/speakon-chassis-connectors/speakon-chassis-connectors/ up to 8-pole and airtight for audio applications (leakage 30 cm3/s at 10 kPa differential pressure)
[10:43:41] <CaptHindsight> current rating for some is up to 30A per contact
[11:04:09] <JT-Shop> heh
[11:16:49] <Loetmichel> re @ home
[12:11:59] <IchGuckLive> hi all B)
[12:18:03] <IchGuckLive> !seen asah
[12:18:04] <the_wench> last seen in 2013-12-28 22:22:22GMT 19:39:46 ago, saying Quit: asah
[13:21:18] <IchGuckLive> asah: Hi did you solve the pin problewm
[13:21:29] <IchGuckLive> i read the logs
[13:21:44] <IchGuckLive> you wanted to put 2 pins ??
[13:22:01] <asah> I made an out pin on my comp so I could visualize...
[13:22:02] <asah> =(
[13:22:15] <IchGuckLive> yes
[13:22:26] <IchGuckLive> and to a pyvcp led
[13:22:27] <asah> basically a pass through pin. this seems like a largish limitation.
[13:22:29] <asah> yes
[13:22:43] <IchGuckLive> and where is the problem
[13:22:46] <asah> it would be nice if there could be more of a DAG like connection.
[13:22:52] <IchGuckLive> anable=enabled
[13:23:10] <IchGuckLive> or the other way
[13:23:18] <asah> so you could wire something into multiple locaitons.
[13:23:29] <IchGuckLive> yes
[13:23:40] <IchGuckLive> you can put a signal to more then one location
[13:23:42] <asah> basically a silent, inline, "or" node
[13:23:58] <IchGuckLive> or2 is available
[13:24:04] <asah> right.
[13:24:18] <IchGuckLive> so whee is the problem
[13:24:42] <asah> I have worked with a ton of node based systems that don't require a 1 to 1 connection between any node.
[13:25:28] <asah> how do I connect an existing signal into a pin?
[13:25:32] <asah> I must be missing something.
[13:25:49] <asah> signals are basically named connections between pins from what I can tell.
[13:25:49] <IchGuckLive> net sigout pin
[13:26:04] <IchGuckLive> lets make a example
[13:26:54] <IchGuckLive> net switchx <= hm2_5i25.0.7i76.0.0.input-10
[13:27:01] <asah> are there limitations on that destination pin?
[13:27:08] <IchGuckLive> now switchx holds the signal
[13:27:31] <pcw_home> signals are wires, pins are nodes (only one driving node is allowed per signal)
[13:27:59] <asah> but a signal can be a source for many pins?
[13:28:08] <IchGuckLive> pcw is wright for more use a OR2 AND
[13:28:50] <pcw_home> and the driving node is hm2_5i25.0.7i76.0.0.input-10
[13:29:04] <pcw_home> yes and many as you like
[13:29:10] <pcw_home> as many
[13:29:24] <IchGuckLive> loadrt or2 count=4
[13:29:27] <asah> so if I want switchx to drive 3 entities I would need to inline "or" nodes?
[13:29:28] <IchGuckLive> addf not.0 servo-thread
[13:29:28] <IchGuckLive> addf not.1 servo-thread
[13:29:28] <IchGuckLive> addf not.2 servo-thread
[13:29:30] <IchGuckLive> net remote-speed-slow or2.0.in0 input.0.btn-a
[13:29:32] <IchGuckLive> net remote-speed-medium or2.1.in0 input.0.btn-x
[13:29:34] <IchGuckLive> net remote-speed-fast or2.0.in1 or2.1.in1 input.0.btn-y
[13:29:50] <IchGuckLive> not0or2 Sorry
[13:30:04] <pcw_home> no it can drive any number of hal 'in' pins
[13:30:16] <IchGuckLive> as entries YES
[13:30:22] <IchGuckLive> as outgoing NO
[13:30:46] <pcw_home> but only one 'out' pin (like hm2_5i25.0.7i76.0.0.input-10) per signal
[13:31:11] <asah> I suppose that is the limitation.
[13:32:14] <asah> it seems logical that a given input (like hm2_5i25.0.7i76.0.0.input-10) could drive many other pins in various ways.
[13:32:15] <pcw_home> well how do you define what happens when two sources connect to the same net?
[13:32:19] <IchGuckLive> is it a AND input or an OR
[13:32:23] <pcw_home> It can
[13:32:40] <asah> (I am probably being very confused here)
[13:32:42] <asah> ok
[13:32:45] <pcw_home> it can drive as many as you like
[13:32:48] <IchGuckLive> so the source maybe 3 buttons for one event
[13:32:59] <pcw_home> (its a hal out pin)
[13:33:22] <asah> so hm2_5i25.0.7i76.0.0.input-10 is a hal out or in?
[13:33:34] <IchGuckLive> in
[13:33:34] <asah> this is the source of my missunderstanding I think.
[13:33:51] <pcw_home> No its a HAL OUT pin
[13:34:14] <pcw_home> out meaning it sources data to HAL
[13:34:34] <IchGuckLive> pcw_home: its sourcing the interpreter from your mesa board so its a in
[13:34:41] <asah> so it seems that many other nodes should be able to be driven by that one OUT connection.
[13:35:06] <asah> no?
[13:35:31] <asah> and you are saying I can make a signal out of hm2_5i25.0.7i76.0.0.input-10
[13:35:43] <asah> and use that signal to drive other HAL IN pins?
[13:36:04] <JT-Shop> asah, http://linuxcnc.org/docs/devel/html/hal/basic_hal.html
[13:36:05] <IchGuckLive> the input from the mashine can necer source a out driver stage
[13:36:39] <IchGuckLive> i did this 40+ times yesterday on the plasmas
[13:36:52] <pcw_home> hm2_5i25.0.7i76.0.0.input-10 is a HAL out pin and can drive as many HAL input pins as you like
[13:37:15] <IchGuckLive> THATS wright
[13:37:22] <pcw_home> hm2_7i76e.0.7i76.0..input-31 0.000000 0
[13:37:22] <pcw_home> 32774 bit OUT TRUE
[13:37:24] <IchGuckLive> but it will confuse asah
[13:37:24] <asah> directly or through signals?
[13:37:34] <IchGuckLive> true signals
[13:37:43] <IchGuckLive> but in one line
[13:37:53] <asah> so I make a signal first, then push that signal into the destination INs?
[13:38:03] <IchGuckLive> yes
[13:38:17] <asah> but I cannot have that PIN drive more than one SIGNAL
[13:38:41] <IchGuckLive> net mysig hm2_7i76e.0.7i76.0..input-31-not axis.0.home-sw-in axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in
[13:39:03] <IchGuckLive> or
[13:39:05] <IchGuckLive> net mysig hm2_7i76e.0.7i76.0..input-31-not
[13:39:15] <IchGuckLive> net mysig axis.0.home-sw-in
[13:39:31] <IchGuckLive> net mysig axis.0.neg-lim-sw-in
[13:39:31] <pcw_home> net foobar hm2_5i25.0.7i76.0.0.input-10 pin_x pin_y pin_z
[13:39:41] <IchGuckLive> net mysig axis.0.pos-lim-sw-in
[13:39:56] <IchGuckLive> fore more then one line
[13:40:08] <asah> ok, thats the wall I hit.
[13:40:18] <IchGuckLive> one pin at my plasmas is driving all home limit
[13:40:47] <asah> I was trying assign the pin multiple times to multiple signals.
[13:41:08] <IchGuckLive> so you can go for all 9 switches in a chain
[13:41:21] <asah> so it sounds like signals are more like what I am used to to connect things together.
[13:41:47] <IchGuckLive> no load the signal and then drive it trou the destination
[13:41:52] <asah> I thought a signal was more like a named connection between two pins, but if I can turn a pin into a signal all by itsself, then connect it to other things later, that is what I am looking for.
[13:42:08] <IchGuckLive> asah: what mashine is it
[13:42:16] <asah> 3 axis mill
[13:42:20] <asah> maho 400e
[13:42:29] <JT-Shop> asah, see the example here http://linuxcnc.org/docs/devel/html/hal/basic_hal.html
[13:42:35] <IchGuckLive> drivven by 7i77
[13:42:37] <pcw_home> signals are like wires and pins are endpoints
[13:42:45] <JT-Shop> Figure 2. Signal Direction
[13:43:08] <asah> byt in the above example you have a signal only connected to a pin : net mysig hm2_7i76e.0.7i76.0..input-31-not
[13:43:16] <asah> so thats a very short wire =)
[13:43:45] <IchGuckLive> this is the source
[13:44:06] <IchGuckLive> and mysig holds the value
[13:44:22] <IchGuckLive> True if off and False if on
[13:44:27] <asah> that is exactly what I am looking for. the confusing bit for me was the signal definitions with multiple pins on the line.
[13:45:17] <IchGuckLive> humen reading is different to hal
[13:45:27] <asah> so I like your example IchGuckLive where you connect the signal to one pin, essentially giving it a nice named handle, then wiring it up later on.
[13:45:43] <IchGuckLive> agree
[13:45:45] <asah> Ill use that route. thanks!
[13:45:54] <Tom_itx> a signal can source only one output though?
[13:46:53] <archivist> if you wish to AND/OR outputs us a comp to do that
[13:47:00] <IchGuckLive> asah: are you running the 7i76e
[13:51:29] <asah> no, I have servos, driven by a 7i83
[13:51:47] <IchGuckLive> ok im off BYE
[13:54:14] <pcw_home> (VHDL has output types you can wire together and get wire-or and wire-and behaviour)
[15:34:55] <Jymmm> Has anyone tried PULSING a SSR by chance?
[15:48:53] <Tom_itx> Finally, an electronic relay can be pulsed very fast. Nope, we’re not talking about just switching on and off a few times a second, but instead being pulsed hundreds of times per second
[15:48:57] <Tom_itx> http://www.autospeed.com/cms/A_112737/article.html
[15:50:06] <Jymmm> nice
[15:50:08] <Jymmm> ty
[15:50:35] <Tom_itx> no personal experience
[15:51:23] <Jymmm> Yeah, I think I'd need a HUGE heatsink too
[15:51:26] <skunkworks> depending on the ssr - you may only be able to pulse it at the 60hz rate
[15:51:48] <Tom_itx> yeah, some are made for pulsing
[15:52:18] <eric_unterhause1> I would guess a big heatsink would be a good idea
[15:52:25] <Tom_itx> http://www.thomasnet.com/profile/00686451/schneider-electric-magnecraft.html?what=Pulse+Solid+State+Relays&cov=NA&heading=96219250&searchpos=1&cid=686451
[15:52:57] <Tom_itx> Manufacturer of AC/DC solid state pulse programmable relays
[15:55:35] <Jymmm> Eh $44 http://www.mouser.com/ProductDetail/Magnecraft-Schneider-Electric/6425AXXSZS-AC90/?qs=QXs58j9tPLt/c77DPHrD9Q==
[15:57:18] <Jymmm> Heh, the heatsink http://magnecraft.thomasnet.com/Asset/SSR-HS-1_W_CLASS6.gif
[16:03:36] <eric_unterhause1> have I complained about grub2 today?
[16:10:56] <eric_unterhause1> good news is xenomai kernel boots
[16:11:47] <eric_unterhause1> I hope my latency isn't smi related because the smictrl couldn't find any smi enabled chipsets
[16:17:05] <eric_unterhause1> what is the regression testing doing when it says "recieves banana mango"
[16:18:18] <eric_unterhause1> what is linuxcnc dev chat?
[16:18:34] <eric_unterhause1> what is name of ^
[16:23:22] <Tom_itx> linuxcnc-devel
[16:23:27] <ries> eric_unterhause1: it's possible to turn off SMI just in case you are wondering
[16:23:57] <eric_unterhause1> ries: looks like bios only on my machine
[16:24:11] <ries> you lucky....... :)
[16:24:14] <eric_unterhause1> I am not sure I have the problem
[16:24:33] <eric_unterhause1> just installed xenomai to see if it's kernel related
[16:24:40] <ries> I run LinuxCNC of a old laptop where I had SMI, only way to get reliable pulses was to turn on all fans, then turn off SMI during boot
[16:25:22] <eric_unterhause1> it's been a while since I ran the livecd version on it, had good results with that
[16:25:40] <eric_unterhause1> at least as I remember
[16:25:53] <eric_unterhause1> xenomai regression tests passed
[16:35:10] <eric_unterhause1> I am building linuxcnc in order to get a latency test, huh
[16:36:27] <eric_unterhause1> xeno latency gives me numbers I don't understand
[16:37:30] <eric_unterhause1> have to go to the basement to see if I can spike it
[16:46:04] <eric_unterhause1> darn, that did it
[16:46:24] <eric_unterhause1> 851 microseconds
[16:46:34] <eric_unterhause1> might have to give up
[16:53:55] <Deejay> gn8
[17:02:10] <eric_unterhause1> on ubuntu, does installing vesa drivers uninstall radeon drivers?
[17:24:13] <eric_unterhause1> I forgot what a cluster changing video drivers is
[17:34:07] <eric_unterhause1> I can't believe that linux is moving away from X
[17:34:40] <eric_unterhause1> I hope there is a schism that maintains it, because the new thing is going to be a pain to use from remote systems
[18:27:56] <eric_unterhause1> amd says, "kernel source no longer required if kernel headers are present"
[18:28:12] <eric_unterhause1> then when installing, it says "not built because kernel source not available"
[18:28:23] <eric_unterhause1> confidence inspiring
[18:31:53] <eric_unterhause1> anyone know how to install vesa drivers in ubuntu 12.04? Google fails me
[18:32:49] <eric_unterhause1> all the hits are how to fix other drivers
[18:34:55] <jdh> have you considered not installing vesa drivers and fixing other drivers instead?
[18:35:12] <eric_unterhause1> well, I'm trying to track down a latency problem
[18:35:33] <eric_unterhause1> it appears to me that it's video driver related because I can exercise it with firefox
[18:35:57] <eric_unterhause1> my test shows no latency spikes if I use firefox from a remote machine
[18:36:22] <eric_unterhause1> I have never seen a suggestion that would lead me to believe I can fix the other drivers
[18:36:31] <jdh> how is it if you don't use firefox at all?
[18:36:58] <eric_unterhause1> I assume it will eventually blow up on some graphics task
[18:38:21] <Tom_itx> http://askubuntu.com/questions/145821/how-do-i-force-x-to-use-the-vesa-driver
[18:38:26] <Tom_itx> dunno if that will help or not
[18:38:39] <eric_unterhause1> thanks
[19:00:57] <eric_unterhause1> maybe I shouldn't run firefox
[19:08:11] <eric_unterhause1> I find it a little scary that firefox would set off latency spikes, but I can run as many glxgears instances as I want and still only gets up to about 8uS
[19:08:56] <eric_unterhause1> with firefox, opening a couple of tabs blows it all the way to 1 mS
[19:11:47] <micges> bare firefox? no flash pages?
[19:12:05] <eric_unterhause1> I think I can do it just loading the linuxcnc wiki pages
[19:12:16] <eric_unterhause1> although I usually load gmail, which I think uses flash
[19:12:38] <micges> maybe ff uses gpu?
[19:13:40] <eric_unterhause1> I'll go try just loading wiki pages
[19:26:16] <eric_unterhause1> oh, well, something knocked it up to .9 mS before I got there
[19:42:17] <pcw_home> micges: solved the latency issue (4 mS occasionally) with my home desktop and hm2-ether/Preemt_RT by adding a RTK8139 Ethernet card
[19:42:36] <micges> oh
[19:43:14] <pcw_home> I will run cheerfully at 2 KHz if i dont run flash videos :-)
[19:43:17] <micges> old hardware and simple drivers it seems
[19:43:52] <micges> that's very good
[19:43:55] <Tom_itx> pcw_home what ver xilinx you running?
[19:44:11] <Tom_itx> i just loaded 14.7 but tried to upgrade with no luck
[19:44:23] <Tom_itx> wound up doing the full install again
[19:44:31] <micges> pcw_home: I've added full 3x20 full support to mf, but still fighting with windows port
[19:44:48] <pcw_home> I run 9.2 for spartan 2 and 13.1 or 14.3 otherwise
[19:44:51] <micges> (full support means FPGA and FLASH r/w)
[19:45:43] <eric_unterhause1> running liveCD version 10.04 and haven't been able to get it to spike
[19:45:50] <eric_unterhause1> no flash installed though
[19:45:54] <pcw_home> Thats good (fighting with windows is expected :-( )
[19:45:56] <Tom_itx> yeah i still have the 9.2 install as well
[19:46:06] <eric_unterhause1> I did manage to crash firefox though
[19:46:26] <eric_unterhause1> maybe I'll just install 10.04 and get on with it
[19:47:48] <pcw_home> I had really good luck with some random MB at work and Preemt_RT (latency test max of 14 usec)
[19:48:15] <eric_unterhause1> running which os?
[19:48:33] <pcw_home> Ubuntu 12.04
[19:48:37] <eric_unterhause1> huh
[19:48:47] <eric_unterhause1> I am really suspecting video drivers
[19:49:06] <eric_unterhause1> I seem to be able to do anything from a remote computer
[19:49:25] <pcw_home> On may home machine here its obvious that video limits the Ethernet latency
[19:49:38] <pcw_home> s/may/my/
[19:50:38] <pcw_home> try the latency histogram and open a window :-)
[19:51:11] <pcw_home> or halscope the latency while doing various things
[19:51:50] <eric_unterhause1> I can get a huge spike by opening a few firefox tabs on the machine, that doesn't happen on remote
[19:51:54] <micges> pcw_home: what is your onboard mac?
[19:52:10] <pcw_home> I think Atheros
[19:52:50] <pcw_home> let me run lspci
[19:53:08] <pcw_home> Qualcomm Atheros AR8151 v1.0 Gigabit Ethernet
[19:53:26] <micges> thanks
[19:54:43] <pcw_home> also at least on this hardware, the 3.10.xxx Preemt_RT kernel seems unstable, but the 3.12 seems OK
[19:55:01] <eric_unterhause1> did you try xenomai?
[19:55:54] <eric_unterhause1> maybe I'll try the preempt_RT next after I test the vesa driver fix
[19:56:05] <eric_unterhause1> in 10.04, the ati drivers don't cause problems
[19:56:19] <pcw_home> They have been improved
[19:56:20] <eric_unterhause1> open-source ati drivers, that is
[19:57:38] <pcw_home> I might like to try the VESA fix but the instructions give me a headache
[19:59:45] <eric_unterhause1> yeah, it's rediculous
[20:00:23] <eric_unterhause1> I was thinking about switching my wife to ubuntu, but not any more
[20:01:53] <pcw_home> Yeah they've got their clever little fingers into everything
[20:01:55] <pcw_home> But I'm happy that I can make the Ethernet stuff work on a random PC on Ubuntu at 1 KHz
[20:02:21] <eric_unterhause1> that's pretty good
[20:06:46] <pcw_home> now if the Preemt_RT kernel would support the RTK8168 (the stock Ubuntu one does) things would be hunky-dory
[20:06:48] <eric_unterhause1> I think there is something about the newer kernels that screws things up
[20:07:25] <pcw_home> Yes "progress"
[20:08:00] <eric_unterhause1> there are a couple of ubuntu fanbois on the ubuntu forum that talk about how great it is that linux keeps changing
[20:08:11] <eric_unterhause1> kind of wish it would get better instead
[20:08:31] <jdh> I thought this was the year of linux on teh desktop
[20:08:32] <eric_unterhause1> maybe I need to start a movement
[20:09:10] <eric_unterhause1> let's make it the year of fixing linux
[20:14:24] <pcw_home> This machine has 62 usec or so of latency with Preemt_RT
[20:15:00] <pcw_home> (playing flash videos on firefox glxgears etc)
[20:15:47] <pcw_home> (Core Duo 2180, intel graphics)
[20:16:02] <eric_unterhause1> since I'm not developing anything on my machine, maybe I should just run the old version of linuxcnc
[20:16:55] <pcw_home> maybe try Preemt_RT
[20:17:15] <eric_unterhause1> I suppose, but 6uS latency is hard to ignore
[20:17:41] <eric_unterhause1> well, looks like I managed to hose X ;)
[20:19:29] <pcw_home> 6 usec on the latency test is often quite optimistic (Some of the Atom MBs show this but if you measure the latency
[20:19:30] <pcw_home> with hardware its more like 50)
[20:19:42] <eric_unterhause1> how do you do that?
[20:20:04] <eric_unterhause1> you mean logic analyzer?
[20:20:15] <pcw_home> toggle a I/O bit and watch on a a scope
[20:21:08] <eric_unterhause1> makes sense that i/o latency is more, pc mobo manufacturers don't care about it
[20:21:41] <pcw_home> physical I/O may be blocked by hardware (but latency test does no I/O)
[20:23:16] <eric_unterhause1> I long for the day when the kernel boot was controlled by grub.conf and the video driver was controlled by xorg.conf
[20:23:27] <eric_unterhause1> what was so horrible about that?
[20:25:54] <pcw_home> Ubuntu strives to be like windows and develop that windows talent for breaking itself
[20:26:09] <eric_unterhause1> it's ok as long as things are working
[20:26:17] <eric_unterhause1> infuriating if things don't work
[20:26:18] <jdh> lilo.conf
[20:26:27] <eric_unterhause1> jdh, that's my joke
[20:27:00] <eric_unterhause1> I think the grub devels did a bait and switch
[20:27:19] <eric_unterhause1> and grub2 is just lilo, which grub killed because it was so much easier
[20:27:50] <cradek> eric_unterhause1: all you have to do is use debian instead of ubuntu and all that bullshit is gone
[20:28:14] <eric_unterhause1> I guess I will have to do that
[20:28:17] <cradek> it boots in text mode. then later, x starts
[20:28:45] <cradek> it's such a relief to have a usable console again
[20:29:21] <cradek> I have been unable to remove all the console-hiding bs from my latest ubuntu install
[20:29:27] <eric_unterhause1> you can get a console on ubuntu, the old fashioned way
[20:29:41] <eric_unterhause1> ctl-alt-f1
[20:29:52] <cradek> sure if all your early video driver crap works
[20:30:02] <cradek> but the boot messages and shutdown messages are still hidden
[20:30:16] <cradek> and grub is hidden (but at least that's easy to fix)
[20:30:26] <eric_unterhause1> ya, that's too much info for my delicate mind :)
[20:31:07] <eric_unterhause1> I'm not convinced that switching distros will fix my problem, seems drastic
[20:36:37] <eric_unterhause1> my local mirror has hidden debian isos
[20:43:50] <eric_unterhause1> hopefully comcast doesn't discover I'm torrenting a file, the horror
[20:49:38] <skunkworks> I had a hard time getting xenomai to run decently on my hardware.. (mostly amd) I think it ended up being the audio card had to be disabled. Idle=poll also make the latency stay low. I don't remember if disabling lagacy usb helped or not. Used the xenomai trouble shooting docs
[20:53:58] <eric_unterhause1> skunkworks: no audio, idle=poll
[20:54:18] <eric_unterhause1> legacy usb is only active in bios setup
[20:56:16] <eric_unterhause1> only thing I can think of is the video
[20:56:29] <eric_unterhause1> at least, that's the only thing I can think of that I can change
[21:03:57] <tjtr33> has Unified Build been tried on a Cubieboard?
[21:06:45] <eric_unterhause1> I have seen no mentions of the cubieboard
[21:08:18] <eric_unterhause1> bittorrent is really good at slowing down the network
[21:47:46] <eric_unterhause1> ha, so I finally managed to load the vesa drivers and latency is 15 uS on both rtai and xenomai
[21:48:06] <eric_unterhause1> not sure why the machine hangs on reboot though
[21:50:56] <eric_unterhause1> actually, I remember managing to spike the latency to 15uSec on livecd
[22:06:16] <eric_unterhause1> anyone know why git keeps telling me Michael Haberler's github repository isn't a git repository?
[22:06:46] <skunkworks> what command are you using?
[22:07:00] <eric_unterhause1> git remote add github-mah https://github.com/mhaberler/linuxcnc.git
[22:07:54] <eric_unterhause1> if you follow that link, it has a little box that gives you that same link as the git clone address
[22:09:06] <eric_unterhause1> I think there may be a step I'm missing
[22:09:29] <skunkworks> are you in your linuxcnc rip directory?
[22:09:46] <eric_unterhause1> I am in a directory I just made
[22:09:54] <skunkworks> is it empty?
[22:10:00] <eric_unterhause1> no
[22:10:13] <eric_unterhause1> it has to be empty?
[22:10:18] <skunkworks> heh - no
[22:10:22] <skunkworks> what is in it?
[22:10:31] <eric_unterhause1> some mesa stuff
[22:10:49] <skunkworks> it needs to have a linuxcnc source
[22:11:08] <eric_unterhause1> that's what I'm trying to get from the git repository
[22:11:13] <skunkworks> then you use
[22:11:15] <skunkworks> git clone --branch unified-build-candidate-3 --origin github-mah https://github.com/mhaberler/linuxcnc.git [<directory>]
[22:11:39] <eric_unterhause1> ic
[22:12:15] <skunkworks> http://static.mah.priv.at/public/html/common/UnifiedBuild.html#_configuring_and_building_the_basic_procedure
[22:12:37] <eric_unterhause1> okey, misread
[22:15:15] <eric_unterhause1> wish I could remember the command for missing deps
[22:21:31] <eric_unterhause1> now I know why I keep thinking I've done this recently, I installed it on a 64 bit system and then decided to wipe it
[22:26:51] <eric_unterhause1> txlive install taking forever
[22:45:26] <eric_unterhause1> pcw, I managed to get the vesa drivers installed and my latency spikes went away
[22:47:38] <eric_unterhause1> you have to blacklist the current driver and make sure that vesa_fb is not blacklisted in the /etc/modprobe/blacklist-framebuffer file
[23:20:21] <tjtr33> eric_unterhause1, help me understand what you did... linuxcnc on 12.04 with xenomai with 6uS latency, but what hardware? and is it UBC3?
