[08:20:24] <skunkworks> wierd issue with linuxcnc/debian/cinnamon When I launch linuxcnc - it isn't active. (seems to be minumized in the task bar) and clicking on it doesn't bring it up.
[08:21:21] <skunkworks> right clicking on the task bar item and 'restore' seems to bring it up.
[08:21:50] <skunkworks> I think I noticed this on my laptop when I was trying out gnome (debian jessie also)
[08:22:04] <jepler> then use xfce or openbox
[08:22:07] <jepler> shitty window manager is shitty
[08:24:25] <skunkworks> ok. Mate seems to work ok. I have not tried xfce
[08:24:41] <skunkworks> *openbox I mean. Wow I need some coffee
[08:40:22] <jepler> so do I, I'm crabby and irritable so far this morning.
[08:55:13] <pcw_home> I have the same thing with Cinnamon/Mint but there, clicking on the icon does work
[08:56:01] <pcw_home> (that is, it starts up minimized)
[09:02:03] <skunkworks> sometimes it does come up when you click on it. No clue
[09:03:40] <skunkworks> how does xfc know to put linuxcnc as the first program no matter what is up?
[09:06:04] <skunkworks> (on the livecd)
[09:06:32] <mozmck> skunkworks: you mean first in the list of running programs on the taskbar?
[09:06:43] <skunkworks> yes
[09:14:55] <JT-Shop> is there a 7i92_7i76_7i85s.bit file anywhere?
[09:15:16] <mozmck> xfce sorts the programs on the taskbar for some reason, but you can turn that off in the panel settings
[09:22:43] <mozmck> skunkworks: the settings are actually in the window buttons settings - not panel. It is called Window grouping
[09:23:30] <pcw_home> JT-Shop maybe, let me check
[09:24:20] <JT-Shop> thanks
[09:33:03] <pcw_home> Theres a pinout file but no bit files AFAIK, I'll build one here, will take a few minuts
[09:35:55] <JT-Shop> thanks

[10:28:50] <emcPT> Hello. Are the conversations recorded? I would like to review my talk with jepler, cradek and seb_kuzminsky seeking for guidance and I did not copy the conversations. Thank you
[10:32:14] <skunkworks> zlog
[10:34:03] <emcPT> Thank you
[11:04:37] <jepler> didn't spend much time with the xu4 this weekend. built a (non-rt) 4.6.3 kernel but didn't boot it yet
[11:05:18] <jepler> I don't really have a comfort level with uboot; I was trying to figure out a way to switch from the testing kernel to the known good kernel without popping the e-mmc off and mounting it somewhere else to manually move files around
[11:05:32] <jepler> because testing kernels you get a lot of "oh that doesn't even boot, ugh" experiences
[11:07:50] <jepler> >
[11:07:50] <jepler> You need to sign the bl2.bin with Hardkernel's private key to make it bootable.
[11:08:04] <jepler> sigh, the blobs are everywhere
[11:08:10] <jepler> (this is part of the bootloader)
[11:13:28] <seb_kuzminsky> i had some quality time with my U3s this weekend
[11:13:58] <seb_kuzminsky> built a 2x U3 enclosure with a good power supply, good forced air flow, ethernet jacks
[11:14:20] <jepler> you have two of them?
[11:14:24] <seb_kuzminsky> installed the wheezy-armhf buildslave U3 in it, and the U3 jepler sent me like a year ago
[11:14:34] <seb_kuzminsky> the second one will be a jessie-armhf buildslave
[11:14:40] <jepler> ah
[11:15:39] <seb_kuzminsky> nothing real exciting, but i feel good about making the pile of exposed boards, bare power supplies, and random wires and cables on my workbench smaller and tidier
[11:16:02] <jepler> I'm glad that u3 will finally come in handy
[11:16:28] <seb_kuzminsky> and it involved a bunch of runtime on the bridgeport (running 2.7 from the buildbot), and it all went well (no equipment or work pieces ruined, no new linuxcnc bugs found)
[11:16:36] <jepler> yay!
[11:16:38] <seb_kuzminsky> jepler: me too! thanks :-)
[11:16:38] <jepler> pics?
[11:16:58] <archivist> or it didnt happen :)
[11:17:08] <seb_kuzminsky> heh
[11:17:16] <seb_kuzminsky> it looks approximately like this now: http://cdn2.bigcommerce.com/server3100/f89b9/products/254/images/1029/Plastic_SCSI_Enclosure_0240r_front_1000x775_2013a__89020.1388509965.1280.1280.jpg?c=2
[11:17:26] <seb_kuzminsky> except without the cdrom drive
[11:18:00] * archivist expected rack mount beefyness
[11:18:01] <jepler> what will we do when we run out of 90s external scsi enclosures?
[11:18:25] <seb_kuzminsky> we'll sob into our flimsy 3d-printed craplastic cases
[11:18:54] <jepler> I'd need a 3d printer to have any of those
[11:18:59] <archivist> wot no milled cases
[11:19:02] <jepler> s/a 3d/a working 3d/
[11:20:36] <seb_kuzminsky> jepler: yours is some goofy non-id kins machine, right? might be interesting to try running master on it
[11:21:02] <jepler> seb_kuzminsky: linear delta, yes
[11:21:06] <seb_kuzminsky> mine's a boring little mendlemax with id kins
[11:21:40] <seb_kuzminsky> i think each individual part of it works and i just need to build up the courage to run part program through it
[11:21:55] <seb_kuzminsky> and deal with the inevitable 10 hours of failures that follow
[11:22:05] <jepler> I'd have to buy linuxcnc-appropriate stepper drivers for it, right now it has a rambo-style with integrated stepper drivers
[11:23:29] <seb_kuzminsky> first time i see the rambo, neat
[11:24:13] <seb_kuzminsky> mine has a ramps, and a giant pile of jumper wires where the arduino was, running to a 50-pin screw terminal board connected to a mesa
[11:24:27] <seb_kuzminsky> i should take a picture of it, it's ridiculous
[11:25:43] <seb_kuzminsky> but it lets me reuse the polulu stepper drivers and the high-power circuitry
[11:26:23] <jepler> Yeah it's nice to not have to do the power section
[11:26:49] <jepler> and you involved a teensy for the little bit of ADC?
[11:27:01] <seb_kuzminsky> yeah, based on your arduino-adc thingy
[11:27:24] <seb_kuzminsky> https://github.com/SebKuzminsky/linuxcnc-hal-teensy
[11:27:54] <seb_kuzminsky> oh good, i remembered to credit you in teh README
[11:28:09] <jepler> heh you know I get irked when I'm not credited
[11:28:20] <seb_kuzminsky> well :-)
[11:31:37] <seb_kuzminsky> in the early days of that 3d-printer project i imagined making a new board based on the ramps, but with a mesa 2x25 plug where the arduino-shield plug is now
[11:31:54] <seb_kuzminsky> but that was when i was young and optimistic and naive, now i'm old and gray and jaded
[11:32:23] <jepler> yeah essentially
[11:35:22] <jepler> sitting around in a bin of unfinished circuit board designs: https://emergent.unpythonic.net/files/sandbox/mumps2.png
[11:35:27] <jepler> obviously the name is great
[11:37:12] <jepler> looks like my plan was to have the Mesa talk to an embedded AVR via serial, which would run the ADC and the heaters
[11:37:43] <jepler> one Mesa connector isn't quite enough I/Os otherwise
[11:38:23] <jepler> https://emergent.unpythonic.net/files/sandbox/mumps2-sch.png
[12:05:02] <seb_kuzminsky> jepler: neato
[12:07:01] <seb_kuzminsky> what are the stepper drivers between the 50-pin header and the atmega?
[12:11:28] <jepler> seb_kuzminsky: there are a family of stepper drivers in DIP-ish form factor https://www.pololu.com/category/120/stepper-motor-drivers
[12:13:50] <seb_kuzminsky> oh yeah
[12:38:12] <skunkworks> axis seems to be the only gui that opens minimized
[12:38:17] <skunkworks> odd
[12:41:11] <skunkworks> *here is a nickel get yourself a better windows manager
[12:41:47] <skunkworks> google searching is not helping. Everyone wants an application to start minimized.
[12:44:50] <JT-Shop> pcw_home: thanks
[13:50:30] <jepler> skunkworks: shot in the dark, comment out the hal manualtoolchange thing
[13:50:44] <jepler> second shot in the dark, figure out how to disable the splash screen
[13:50:59] <jepler> these window managers may be confused, because it looks like 3 "applications" starting at the same time
[13:51:49] <skunkworks> the manual tool change thing isn't it (the matsuura doesn't have that popup)
[13:51:55] <skunkworks> so it could be the splash screen
[14:03:25] <skunkworks> setting INTRO_TIME to zero doesn't stop the spash screen. Removing the INTRO_GRAPHIC doesn't change things
[14:22:03] <pcw_mesa> Axis does come up minimized on Mint/Cinnamon but clicking the icon to restore works reliably (just tried 30 or so times)
[14:39:23] <cradek> weird
[14:43:36] <skunkworks> sure - it does here to. I don't know what the issue was at the shop
[14:51:39] <skunkworks> (but shows up minimized..)
[14:59:18] <seb_kuzminsky> linuxcnc-build: force build --branch=2.7 0000.checkin
[14:59:19] <linuxcnc-build> build #4500 forced
[14:59:19] <linuxcnc-build> I'll give a shout when the build finishes
[15:05:37] <skunkworks> ok - getting rid of the manual tool change popup and removing the splash screen section from the linuxcnc.in and re-making doesn't fix the axis opening minimized.
[15:06:20] <cradek> if you run wish does the window start minimized?
[15:06:55] <linuxcnc-build> build #0 of 1540.rip-jessie-armhf is complete: Failure [4failed apt-get-update compile] Build details are at http://buildbot.linuxcnc.org/buildbot/builders/1540.rip-jessie-armhf/builds/0
[15:07:01] <skunkworks> wish?
[15:07:14] <cradek> at a shell
[15:07:18] <cradek> type wish
[15:07:42] <skunkworks> no - it shows up in a window
[15:07:47] <cradek> hmm
[15:07:53] <jepler> are you launching linuxcnc from terminal or otherwise?
[15:07:57] <cradek> ok I'm done troubleshooting
[15:08:03] <skunkworks> both now
[15:08:16] <skunkworks> (from rip and installed)
[15:08:33] <skunkworks> sorry - I know it is a odd issue.
[15:08:56] <skunkworks> creating a desktop icon also doesn't effect it
[15:08:58] <jepler> yeah and I'm not against diagnosing it, reporting a bug somewhere appropriate, and working around it in linuxcnc if possible
[15:09:35] <jepler> but so far none of our guesses have hit the target
[15:09:55] <skunkworks> let me play some more. bbl
[15:10:09] <jepler> > /bin/bash: /usr/bin/time: No such file or directory
[15:10:11] <jepler> well that's an odd failure
[15:12:20] <seb_kuzminsky> nah, i just forgot to install time.deb
[15:12:41] <seb_kuzminsky> on the new jessie-armhf buildslave you sent me

[15:18:03] <seb_kuzminsky> g++: internal compiler error: Killed (program cc1plus)
[15:18:17] <seb_kuzminsky> hrm
[15:23:44] <seb_kuzminsky> oh, it was oom
[15:24:16] <seb_kuzminsky> interesting that 2.7 builds on wheezy with 2 GB RAM and no swap, but not on jessie
[15:28:39] <andypugh> Someone has noted that the forum shows everyone offline, regardless of whether they are or not.
[15:29:15] <andypugh> I can’t say it bothers me particularly, but if anyone has ideas for an easy fix….
[15:32:10] <jepler> andypugh: is this a recent change?
[15:32:27] <jepler> seb_kuzminsky: the jessie compiler uses a lot more RAM than either the Wheezy or Stretch one
[15:32:28] <andypugh> I think the first person mentioned it a few weeks ago
[15:33:09] <andypugh> Yes, first mentioned on the 5th August
[15:33:47] <jepler> I have no idea how the forum decides if someone is online
[15:33:56] <jepler> I thought maybe andypugh would be defined as online so I went to http://forum.linuxcnc.org/forum/38-general-linuxcnc-questions/31482-tool-length-tool-change-offsets-a-total-mess#79690
[15:34:08] <jepler> and I notice that the poster on the post just above his is marked online right now
[15:34:18] <andypugh> So he is
[15:34:34] <andypugh> But I am not
[15:34:38] <andypugh> Were you?
[15:35:01] <jepler> I'm browsing the forum right now logged it
[15:35:03] <jepler> logged in
[15:35:20] <andypugh> Hmm, I logged out and in again, and now I am online.
[15:35:45] <jepler> ditto here
[15:35:52] <andypugh> It’s purely a cosmetic issue, has no effect on whether you can posr or not, or see undread-posr tags
[15:37:14] <andypugh> Maybe a quirk in the “remember me” option?
[15:38:49] <jepler> could be. I think I use that option when logging in
[15:39:44] <jepler> if it's a joomla / community builder / kunena bug, then there's about zero chance of it getting fixed by me
[15:44:19] <linuxcnc-build> build #4500 of 0000.checkin is complete: Failure [4failed] Build details are at http://buildbot.linuxcnc.org/buildbot/builders/0000.checkin/builds/4500

[17:49:24] <linuxcnc-build> Hey! build 0000.checkin #4501 is complete: Success [3build successful]
[17:49:24] <linuxcnc-build> Build details are at http://buildbot.linuxcnc.org/buildbot/builders/0000.checkin/builds/4501
[18:17:34] <andypugh> Is there a uspace LiveCD? ie, can someone install from LiveCD and run a Mesa ethernat board?
[18:20:35] <pcw_mesa> You can by adding the uspace package
[18:29:37] <skunkworks> and the rt-preemt kernel
[18:58:56] <pcw_mesa> I think the package brings in the kernel (or used to)
[19:00:27] <skunkworks> hmm - maybe. Haven;t done that in a while
[19:01:56] <pcw_mesa> I've had to build newer kernels for recent hardware
[19:12:42] <cradek> bought a cute little tek 314 storage scope, mostly dead, for $10. thought that would be worth digging into, maybe fixing, but now I see on ebay you can get them working for way under $100
[19:12:46] <cradek> I might do it anyway
[19:24:15] <skunkworks> ran my 2nd stirling in reverse and got 80deg temp differential at 100 rpm.
[19:24:54] <skunkworks> don't ask me if that is good - I am just glad it seems to 'stirling,,'
[19:25:00] <cradek> neat!
[19:25:18] <cradek> now hook a bicycle to it and boil water for coffee
[19:25:26] <cradek> that would be extremely hipster
[19:25:33] <skunkworks> heh
[19:26:01] <skunkworks> Hmm - I see a youtube video in my future.. the hot side got to 140f ish
[19:26:13] <cradek> ok, green tea I guess
[19:26:31] <skunkworks> that was with helium as the gas at only 20 lbs,
[19:29:21] <andypugh> cradek: 214 does look quite cute. I have a 336 which is about the same size but perhaps more capable.
[19:29:54] <andypugh> Except for not running of 12V
[19:30:02] <cradek> I hope it's a basic power supply problem
[19:30:12] <cradek> it was easy to find the service manual
[19:30:47] <andypugh> 336 has on-screen menus done in vector fonts. Must have been expensive at the time.
[19:31:07] <cradek> oh yeah I'm sure this one's not digital at all
[19:31:29] <cradek> my 2232 (or is it 3323) is digital/analog with the vector fonts
[19:31:33] <cradek> a nice blend
[19:33:01] <andypugh> The 336 is labeled “digital storage” but I think it is only the storage that is digital. Pretty sure than normal mode is analogue.
[19:33:35] <andypugh> It still has features I don’t know how to use.
[19:33:53] <cradek> heh, pretty much every scope is like that for me
[19:33:59] <cradek> I've never read a manual
[19:37:04] <andypugh> Anyway, taxi for the airport arrives in 6 hours. Should get some sleep. :-)
[19:37:40] <cradek> g'night, safe trip
[19:38:14] <andypugh> For the next two weeks I am likely to be online lots, or not at all, depending on how the job is going, and what the hotel WiFi is like.
[19:59:41] <jepler> andy: safe travels
