[02:54:38] <micges-dev1> 5+
[03:12:01] <memfrob> micges-dev1, 5+ ?
[03:53:44] <micges-dev1> memfrob: sorry my 1yr old hack got to keyb ;)
[13:18:21] <fenugrec> (copied from #linuxcnc) I would have a small patch to propose for /docs/src/install/Latency_Test.txt ; just a few words mentioning "hdparm -tT /dev/sda" as an excellent way to test worst case jitter. Where can I submit it for review ? do I file a bug somewhere
[14:32:23] <micges-dev> pcw_home: is SSLBP Clock: 1717 MHz correct data?
[14:33:22] <pcw_home> no
[14:33:50] <micges-dev> ok
[14:34:55] <pcw_home> the CPU/UART clock is 100 MHz on Spartan6 FPGA cards (50 on SP2 75 or 72 on SP3)
[14:37:04] <micges-dev> oh ok
[14:38:15] <pcw_home> not actually needed for anything since the SSLBP firmware calculates baud rate settings etc
[14:38:17] <pcw_home> The firmware reads a register that has the (constant) SSLBP clock for this purpose (constant compiled-in)
[14:38:36] <micges-dev> on my 7i77 just format of interface regs left
[14:39:01] <micges-dev> yeah I just want data to be reported correctly
[14:39:21] <pcw_home> that stuff is from discovery (there's no card specific stuff in the driver for example)
[14:40:09] <pcw_home> (well only for 7I64 and 8I20 which were pre-discovery system)
[14:41:44] <pcw_home> data is always just packed in the discover process data record order
[14:43:17] <pcw_home> do you have the source to "info"
[14:43:37] <pcw_home> it prints a bunch of sslbp stats
[14:43:49] <micges-dev> just looking at it atm
[14:52:47] <pcw_home> bbl beachtime!
[14:55:36] <micges-dev> have fun
[17:29:23] <micges-dev> pcw_home: 7i77 analog part works perfectly
[19:31:23] <jepler> time to work on merging uspace with master branch, and test all my handy hardware again (5i20, 7i43, parport, serport)
[19:31:46] <jepler> It'll probably take all weekend, I want to test it under rtai too, but that means doing a fresh install (we're still not shipping an rtai for 64-bit systems)
[19:37:18] <jepler> er, all evening .. weekend's almost used up
[19:37:20] <jepler> (boo)
[19:39:43] <jepler> boo, master branch has new building problems in userspace.
[19:39:52] <jepler> I wonder if it has some #ifdef sim's or something
[19:55:20] <jepler> yup
[20:02:24] <jepler> Your branch and 'origin/jepler/rtos-uspace-apis' have diverged,
[20:02:25] <jepler> and have 543 and 43 different commits each, respectively.
[20:03:10] <jepler> hm, pushing this will generate way too many e-mails
[20:03:19] <KGB-linuxcnc> 05jepler/rtos-uspace-apis 0fc7ad3 06linuxcnc 04. branch deleted * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=0fc7ad3
[20:03:39] <jepler> but I think if it's the first push to a new branch, no e-mails are generated... ?

[21:17:05] <cradek> ooh, does that mean success?
[21:17:11] <jepler> cradek: close
[21:18:10] <KGB-linuxcnc> 03Jeff Epler 05jepler/rtos-uspace-apis 833a345 06linuxcnc New branch with 45 commits pushed, 10117 files changed, 034444(+), 044026(-) since master/cd4180d
[21:20:35] <jepler> hmph, accidentally added a whole file I shouldn't have
[21:20:49] <jepler> create mode 100644 debian/linuxcnc-uspace/usr/share/man/man9/scale.9.gz
[21:21:17] <cradek> uh
[21:21:29] <jepler> yeah, pretty great

[21:24:02] <KGB-linuxcnc> 03Jeff Epler 05jepler/rtos-uspace-apis fe811a7 06linuxcnc New branch with 45 commits pushed, 10116 files changed, 034444(+), 044026(-) since master/cd4180d
[21:24:39] <cradek> I wish buildbot had a oh-just-forget-it button that worked
[21:26:16] <skunkworks> cradek: I think I am going to have to put ilowpass in the wheel jog circuit. It is a bit harsher now..
[21:27:22] <skunkworks> I probed the center of the chuck that is mounted on the K&t.. it was a less than .0015 off from when I probed it a year or more ago..\
[21:28:33] <jepler> skunkworks: what changed to make it "harsher"?
[21:29:10] <skunkworks> I think Y is tuned better - not mushy... x and z maybe are better because of the 'previous target and ff1 adjustment)
[21:29:49] <jepler> ah, the pid retuning we did last month?
[21:29:51] <skunkworks> yes
[21:30:12] <jepler> well, which cradek did
[21:30:16] <jepler> I think we just watched
[21:30:19] <skunkworks> right
[21:30:35] <jepler> linuxcnc-build: watch build 0000.checkin
[21:30:35] <linuxcnc-build> try 'watch <builder>'
[21:30:38] <jepler> linuxcnc-build: watch 0000.checkin
[21:30:38] <linuxcnc-build> watching build 0000.checkin #2242 until it finishes [1h15m54s]..
[21:30:45] <jepler> hmph, I'll be in bed by then
[21:31:47] <cradek> my old qxga thinkpad boots the wheezy live image and everything works, including wifi
[21:31:50] <cradek> whee
[21:33:16] <cradek> weird, it has very good latency too
[21:33:32] <cradek> 12000 with glxgears running
[21:34:25] <cradek> very surprising
[21:37:08] <jepler> sounds like a keeper
[21:37:14] <skunkworks> http://electronicsam.com/images/KandT/testing/stirling/DSC_1952.JPG
[21:37:30] <skunkworks> http://electronicsam.com/images/KandT/testing/stirling/DSC_1955.JPG
[21:37:34] <cradek> jepler: it has a parallel port, too
[21:38:06] <skunkworks> (so I can chuck it up in the K&T and machine the rest of the crank
[21:39:12] <cradek> I don't understand what this is
[21:40:30] <jepler> it must be something to do with that stirling engine, but that's just a guess
[21:42:07] <skunkworks> going to look like this... http://electronicsam.com/images/KandT/testing/Screenshot%20from%202014-06-23%2010:32:46.png
[21:43:06] <skunkworks> the aluminum pie shaped pieces are just so I can chuck up the fiinished end to machine the unfinished end :)
[21:43:42] <jepler> how do they stop it from rotating freely? just friction?
[21:46:22] <skunkworks> yes
[21:47:00] <skunkworks> I might - just because I am an over-doer - put a little lock tight in the shaft area to add a little more friction.
[21:47:07] <skunkworks> but it should be fine
[21:47:26] <skunkworks> plus I am not going to hog on it.
[21:48:34] * jepler belatedly gets that "vise advise" is a pun
[21:52:53] <jepler> huh, in the buildbot logs, it often says: linuxcncrsh: write() failed: Broken pipe
[21:53:29] <jepler> .. in tests that seem to be succeeding
[21:55:04] <jepler> well, if buildbot is happy then in the morning I'll merge uspace
[21:59:56] <skunkworks> we are still waiting on someone ot fix the ethernet branch so it doesn't break pci?
[22:28:02] <Tom_itx> what formats does freecad export?
[22:28:13] <Tom_itx> or import...
[22:37:46] <skunkworks> a few? I don't know - just started playing with it
[22:38:14] <Tom_itx> similar look to solidworks..
[22:38:33] <Tom_itx> i might also have a peek at it
[22:46:20] <Tom_itx> where do you change units at?
[22:52:23] <linuxcnc-build> Hey! build 0000.checkin #2242 is complete: Success [3build successful]
[22:52:24] <linuxcnc-build> Build details are at http://buildbot.linuxcnc.org/buildbot/builders/0000.checkin/builds/2242
[22:53:04] <skunkworks> under preferences - units
[22:53:24] <skunkworks> but it isn't 100% - there are still things that need to be entered in mm
[22:53:41] <skunkworks> (annoying,.. (but hey - it is free)
[22:58:48] <Tom_itx> the only thing i found was 'units for export'
