[00:44:25] <jepler> PCW: am I right thinking that the pin names on a 7i77 come from the firmware on the 7i77 itself? I forget whether we mentioned this before, but at txrx we were briefly confused by the fact that the last analog output had a different enable pin than the rest
[00:44:59] <jepler> I forget the pin names, but the last enable implied it was something to do with a spindle, but it just affected whether the analog out numbered "5" was enabled
[00:45:25] <PCW> All sserial pin names come from the remote device (as does scaling and data packing info)
[00:46:25] -!- patrickarlt has quit [Remote host closed the connection]
[00:46:43] <PCW> (and data type)
[00:47:13] -!- asdfasd has quit [Ping timeout: 244 seconds]
[00:47:43] <PCW> the manual does note that channel 5 is intended for spindle operation and has a separate enable
[00:49:29] <jepler> yeah I do see that now
[00:50:00] <jepler> and you'd break configs to rename any of the pins
[00:50:18] <jepler> probably nothing for it but to call it a learning experience
[00:52:49] <PCW> I should probably have a pin name list in a distributed file
[00:53:37] <brianmorel99> PCW: Thanks, off hand do you know if backorders are allowed on the webs store?
[00:55:03] <PCW> Probably not a great (theres something that times out at 30 days or so requiring a re-order)
[00:55:13] <PCW> not a great idea

[01:02:12] <brianmorel99> the 7i75 will give access to all 25 pins for I/O and protection of the 6i25 right?
[01:04:49] <PCW> all _17_ pins...
[01:06:32] <zeeshan|2> is it possible to display inches per revolution for velocity in axis
[01:06:42] <zeeshan|2> i notice when im in CSS mode, it still displays ipm
[01:07:25] -!- Valen has quit [Quit: Leaving.]
[01:08:25] <PCW> You want to display the circumference?
[01:09:38] <zeeshan|2> when you're milling a feature for example, and you have your feedrate set to 50 ipm in the g-code, the velocity thing shows you actual current speed in inches per minute
[01:10:00] <zeeshan|2> but when im turning something in 'feed per rev' mode, i wish velocity was shown in inches per rev, not inches per min
[01:10:17] <brianmorel99> PCW: Thanks, not in a rush, so I'll wait for the 7i76 so I can get lots of IO pins
[01:11:36] <PCW> No 7I76E?

[06:44:41] <seb_kuzminsky> hm, for 2.6 we have install/update docs both on the wiki (

http://www.linuxcnc.org/docs/2.6/html/common/Updating_LinuxCNC.html)
[06:45:12] <seb_kuzminsky> i think for 2.7 we should try to modernize the git version of the docs and not use the wiki docs
[06:45:21] <seb_kuzminsky> but that's a project for another night!
[06:45:59] <seb_kuzminsky> lol, the 2.6 docs say: This documentation refers to LinuxCNC version 2.6.3-856-gf2ec59a.
[06:46:34] <seb_kuzminsky> i guess that's a build of the version of 2.6 that accidentally had master merged into it

[11:34:39] <archivist> how did you setup
[11:35:14] <poly> wizard and manually
[11:35:24] <poly> it's a 5 axis CNC with mesa board
[11:35:45] <poly> i have custom stepper driver /128

[11:36:39] <archivist> I am just wondering if a soft limit is kicking in
[11:36:44] <poly> i think i need so correct something somewhere in INI but dont know what

[13:42:31] <pcw_home> so the uspace version of linuxcnc will be a package for 2.7?
[13:52:03] <seb_kuzminsky> huh, that build failure is unexpected
[13:53:42] <seb_kuzminsky> pcw_home: yep! :-)
[13:54:59] <seb_kuzminsky> pcw_home: you can apt-get install 2.7.0~pre2 linuxcnc-uspace on lucid, precise, and wheezy right now. It works in all the places the old 2.6 -sim package worked, plus on rt-preempt
[13:55:16] <seb_kuzminsky> which we only support on wheezy, because we're too lazy to build rt-preempt kernels for anything else
[13:55:27] -!- kwallace [kwallace!~kwallace@tmb-252.sonnet.com] has joined #linuxcnc-devel
[13:55:41] <seb_kuzminsky> though if someone wanted it.... it'd be pretty easy to get it building and running on ubuntu precise, i bet
[13:56:18] <pcw_home> Preemt-rt kernels are easy to build
[13:56:33] <seb_kuzminsky> ding ding, we have a volunteer! ;-)
[13:57:28] <pcw_home> pcw@pcw-G41M-Combo:~/linuxcnc-dev$ uname -a

[13:57:33] <seb_kuzminsky> i installed the linuxcnc-uspace debs from linuxcnc.org on my devel laptop:
http://pastie.org/9683175
[13:58:10] <seb_kuzminsky> pcw_home: cool. is that kernel from a deb or hand-built and hand-installed from source?
[13:58:39] <pcw_home> Hand built
[13:59:33] -!- jamesarm97 has quit [Ping timeout: 265 seconds]
[13:59:40] <pcw_home> probably something that can be scripted easily (I just used menuconfig or whatever its called)
[14:00:11] -!- balestrino has quit [Ping timeout: 264 seconds]
[14:00:38] <seb_kuzminsky> the tricky part is making a config that works on as many computers as possible, and building the kernel in a repeatable way
[14:01:20] <pcw_home> Yeah, that why I appreciate the wheezy preemt-rt kernel
[14:01:32] <seb_kuzminsky> the second part is handled by the kernel builder scripts here:
https://github.com/SebKuzminsky/linux-rtai-build
[14:01:46] <seb_kuzminsky> the rt-preempt kernel in wheezy is soooo wonderful
[14:04:06] -!- Antiheld has quit []
[14:05:14] <pcw_home> I guess for preemt-rt on a dist that has no standard preemt-rt kernel you could start with the stock kernel config for the dist
[14:05:15] <pcw_home> and patch + add the preemt-rt switches
[14:05:47] <pcw_home> (there are only a couple)
[14:07:48] -!- karavanjo has quit [Ping timeout: 256 seconds]
[14:07:52] <seb_kuzminsky> that's an option, or you could snag the kernel config from debian's rt-preempt kernel
[14:08:40] <pcw_home> yeah it seems to get along with most anything
[14:12:44] <seb_kuzminsky> the debian folks are good that way :-)
[14:13:02] <seb_kuzminsky> just don't read their mailing lists, *they* dont get along with anyone :-)
[14:13:43] <seb_kuzminsky> linuxcnc-build_: force build --branch=2.6 0000.checkin
[14:13:44] <linuxcnc-build_> build forced [ETA 3h45m11s]
[14:13:44] <linuxcnc-build_> I'll give a shout when the build finishes
[14:14:03] <seb_kuzminsky> hrm, the builder that failed was the precise-amd64 clang builder
[14:14:26] <seb_kuzminsky> it just stopped in the middle of a build, nothing funny on the console or dmesg, i could log in to it, it seemed fine
[14:14:33] <seb_kuzminsky> it was not out of disk
[14:15:16] <jepler> seb_kuzminsky: yuck
[14:15:25] <seb_kuzminsky> pcw_home: i forget, did you test brian morel's new usb rtai kernel?
[14:15:51] <seb_kuzminsky> i looked at his changes and they seem good
[14:16:05] <seb_kuzminsky> i think we can build a new kernel with the same abi number, so the upgrade will be smooth
[14:16:15] <cradek> that would be great
[14:16:20] <cradek> do it do it do it
[14:16:21] <pcw_home> No, I forgot I can try today
[14:16:33] <seb_kuzminsky> didn't someone try it? was it skunkworks?
[14:16:34] <jepler> just to create work for cradek, that might be an important enough change to spin a new live cd too
[14:16:44] <seb_kuzminsky> yeah
[14:16:45] <cradek> I'd absolutely do that
[14:16:51] <seb_kuzminsky> thanks :-)
[14:16:54] <jepler> woo
[14:17:04] <jepler> should push out a 2.6.x too, just to make sure we change *everything*
[14:17:05] <seb_kuzminsky> ok bbl! work! woooo! oh wait, awwww
[14:17:44] <seb_kuzminsky> yeah 2.6 needs a new release now that the gmoccapy surprise-move bug is fixed
[14:18:05] <cradek> is there still a separate remap surprise-move bug?
[14:18:22] <seb_kuzminsky> cradek: yes
[14:18:30] <cradek> ouch
[14:18:32] <cradek> someone should do something
[14:23:10] <skunkworks> run away! RUN AWAY!
[14:23:25] <seb_kuzminsky> cradek: do you have some axis-ui metric/imperial jog fixes brewing somewhere?
[14:23:27] <skunkworks> yes - I tested the usb rtai version and it worked on my hardware that didn't before..
[14:23:41] <seb_kuzminsky> ooooh, nice
[14:23:43] <cradek> seb_kuzminsky: crap, I forgot about that mess
[14:24:38] <cradek> I will try to work on it today
[14:24:41] <seb_kuzminsky> as rm, i take my crap-foisting seriously
[14:25:37] <cradek> I notice that FO still affects jogs, and shift-jog doesn't override it. I was surprised.
[14:26:18] <jepler> seb_kuzminsky: As RM for 2.7 I would like your ruling about the nml sequence number fix that we know breaks nml-over-tcp...
[14:26:30] <jepler> personally I think we should take the fix
[14:31:43] <cradek> seb_kuzminsky: for 2.6?:
http://timeguy.com/gitweb?p=linuxcnc.git;a=log;h=refs/heads/cradek/m19-without-r-defaults
[14:31:54] <cradek> (now I'm finding halfbaked 2.6 fixes everywhere I look)
[14:32:57] <cradek> I think it's pretty clear that a bare M19 doing nothing at all is a bug
[14:34:06] <cradek> I still dislike the timeout stuff, but I think it's as-designed
[14:35:28] <jepler> argh why am I shopping for oscilloscopes? I need one so rarely and the one I have is mostly adequate.
[14:37:54] <skunkworks> heh
[14:38:35] <skunkworks> at the witchita fest - I got to play with a couple digital scopes.. I do really want one but probably use it less than you..
[14:38:57] <archivist> more than one scope is the answer :)
[14:39:26] <archivist> I admit some are hardly if ever used these days
[14:39:49] <cradek> I love my tek that has a crt with full analog mode, but also can do (limited) digital storage
[14:40:05] <cradek> I find full digital scopes very annoying
[14:41:03] <cradek> I think it's a 2232
[14:41:17] <cradek> if it was 4-channel it would be perfection
[14:41:22] <skunkworks> I was annoyed by the delay - but that is fixed by buying expeniver scopes..
[14:41:25] <archivist> I use an old 20meg analogue as the one to be dragged about
[14:41:43] <cradek> skunkworks: or cheaper, paradoxically
[14:42:04] <archivist> got an 8 chan digital for complex
[14:43:22] <cradek> I also have a 466 (analog storage) which I like quite a bit for some things, like very slow signals (you can use the slowly-fading screen in cool ways)
[14:43:37] <cradek> its problem of course is you can't see what happened before the trigger
[14:44:34] * skunkworks hugs halscope...
[14:44:38] <seb_kuzminsky> heh
[14:44:50] <jepler> my scope's a full digital one, dunno the make/model offhand. whatever rigol they were using at TXRX was way better in terms of display and responsiveness..
[14:45:00] <archivist> my sampler frame is a 661 has a 3(iirc) gig plugin
[14:47:33] <jepler> ah, this one
http://www.eevblog.com/forum/reviews/hp-54502a-nearly-vintage-digitizing-scope/
[14:47:38] <pcw_home> I have a 3 gig sampling plugin for my old TEK 11403 I use occasionally for SI issues
[14:47:43] <seb_kuzminsky> i hardly ever us an oscilloscope, and when i do it's for basic stuff, and i'm super happy with my little tek tds something
[14:48:31] <seb_kuzminsky> i got a crazy bro-deal from a previous employer
[14:49:53] <pcw_home> sampling plugins are nice because they tend to have much better signal fidelity (lower overshoot etc that realtime)
[14:51:11] <archivist> I did have a real rare tek a 1ghz realtime analogue from 1960 but the heater went in the crt
[14:51:37] <jepler> hm now I'm worried my scope will break
[14:51:48] <jepler> due to this battery-backed NVRAM
[14:52:14] <pcw_home> 1018 or something? one of those had 4cx250s driving the verticals
[14:52:46] <seb_kuzminsky> cradek: in your branch, the docs for m19 still say R is required (it's not in square brackets)
[14:53:20] <cradek> oops
[14:53:29] <archivist> PCW, 4cx250 yes but the model is 519
[14:53:29] <cradek> and now I forget what even happens if you don't specify Q
[14:53:42] <cradek> maybe it's too half-baked
[14:53:53] <archivist> transmission line deflection plates
[14:53:57] <pcw_home> Thats right 519
[14:55:16] <archivist> so how did they adjust the crt
http://www.collection.archivist.info/archive/DJCPD/PD/2010/2010_11_24_Tektronix_519/IMG_0901.JPG
[14:56:53] <cradek> that's quite a crt
[14:58:09] <seb_kuzminsky> cradek: wow, interp used to require P *or* R for M19? and then do nothing if P was unspecified? that's silly, your change is a good one
[14:58:24] <seb_kuzminsky> also, it looks like Q is optional in interp, but marked as required in the docs
[14:58:45] <cradek> but I think it maybe doesn't wait at all (so always fails) without a Q
[14:59:31] <archivist> there was no vertical amp in the scope, the signal went via a trigger take off then a delay line then straight onto the crt, then to a dummy load so signal was in a matched line
[15:01:00] <cradek> seb_kuzminsky: probably we should figure out how it should work, and then make sure it does that.
[15:01:18] <cradek> seb_kuzminsky: I'm going to work on AXIS first, though
[15:01:41] <seb_kuzminsky> that makes sense
[15:02:13] <seb_kuzminsky> i'll open a ticket to clean up m19 later
[15:02:42] <cradek> thanks

[18:01:11] <cradek> I tested inch and mm xyzabcuvw configs, each displaying in native and other-units mode, and in all 4 cases jog and shift-jog seemed right
[18:01:48] <cradek> there's still the problem of Vel: readout during abc jogs being weird (it scales), but that's a visual bug only
[18:02:06] <cradek> I should also try jogging rotaries in all 4 cases
[18:03:24] <jepler> cradek: seems sane. looks like an 'is_linear_axis(n)' predicate would be useful

[18:06:59] <cradek> I sort of think shift-jog should act as if feed override is 100%, but it's not so clear that's a *bug*
[18:07:29] <cradek> further, in 2.6 probably RO and not FO should affect jogs

[20:44:49] <cradek> thanks for testing, that's great
[20:45:03] <cradek> which half of the bug report did you reproduce?
[20:45:16] <Connor> let me go re-read his report.
[20:47:07] <Connor> basically, you start running a g-code program with several lines of code.. and hit the STOP button.. you'll get movement after the fact.
[20:47:39] <cradek> umm, that has nothing to do with #397
[20:47:54] <Connor> CRAP
[20:48:01] <Connor> Never freaking mind.
[20:48:05] <cradek> or do I have the wrong number?
[20:48:09] <Connor> I'm looking at 394

[20:50:27] <Connor> cradek: Okay, Question: How can you setup Axis so that when it first comes up, it's in Imperial vs Metric (even though everything is configured metric in the ini and hal).
[20:50:49] <cradek> I don't know an easy way to do that
[20:50:58] <cradek> it's an unusual thing to want
[20:51:15] <Connor> I did it HALF way with something in the .axisrc file or some file like that..
[20:51:22] <Connor> but.. it doesn't fully take effect.
[20:51:25] <cradek> you could make it save that, like it saves some of the other view preferences
[20:51:36] <cradek> hm, well maybe it's harder than that, then
[20:52:03] <Connor> Must be more than one variable that toggles metric vs imperial.
[20:52:49] <cradek> https://www.youtube.com/watch?v=9ARjpL44IfE
[20:52:53] <Connor> The REASON is.. Me (and PetefromTN) and lord knows who else use imperial units.. but, these days, the ballscrews come in metric.. and it's just easier / cleaner to configure the ini and hal in all metric
[20:53:19] <seb_kuzminsky> i've set up a couple of machine with metric screws but imperial native machine units in linuxcnc

[20:53:41] <seb_kuzminsky> cradek: that R15 in world mode is really cool
[20:53:49] <cradek> yeah, pretty sure my vmc has a scale of 25400 - who cares
[20:54:40] <cradek> but I'd happily review a patch that makes that AXIS option save
[20:54:43] <Connor> cradek: What do you mean by that ?
[20:55:00] <cradek> the machine is natively micron resolution
[20:55:09] <cradek> so the inch scale is 25400/inch
[20:55:21] <cradek> instead of 10000 or some other inchy scale

[20:56:32] <cradek> I don't know without looking at the code
[20:57:17] <Connor> [TRAJ] has LINEAR_UNITS
[20:57:32] <Connor> which affects the what values you put into the AXIS_# right ?

[22:57:06] <cpresser> however, there is an issue when loading hm2_pci. I get a permission-denied error:
[22:57:09] <cpresser> "Failed to open "/sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0/0000:02:00.0/enable" (Permission denied)"

[23:05:33] <seb_kuzminsky> hi cpresser
[23:05:54] <seb_kuzminsky> as far as i know, no one has tried that kernel
[23:06:00] <seb_kuzminsky> are you using a uspace build?
[23:06:39] <cpresser> yes, uspace
[23:06:43] -!- dnaleromj has quit [Ping timeout: 244 seconds]
[23:07:32] <seb_kuzminsky> you ran the 'sudo make setuid' step after building?
[23:07:40] -!- tjb1 has quit [Read error: Connection reset by peer]
[23:07:55] <cpresser> nope, i use the buildbot.binary package
[23:08:11] -!- nofxx_ has quit [Ping timeout: 256 seconds]
[23:08:19] <seb_kuzminsky> ah
[23:08:31] <seb_kuzminsky> well that should work :-/
[23:09:10] <seb_kuzminsky> can you try it with the 3.2 rt-preempt kernel in the regular wheezy repo instead of the backportes one? or does your computer need a newer kernel for some reason?
[23:09:47] <seb_kuzminsky> also: what version of the linuxcnc-uspace deb are you using?
[23:09:47] <cpresser> ill reboot the machine later
[23:09:54] <cpresser> it did work with the 3.2
[23:10:06] <seb_kuzminsky> aha! that's good info
[23:10:28] <seb_kuzminsky> so something changed between the 3.2 kernel (works) and the 3.14 kernel (doesn't work)
[23:10:57] -!- dnaleromj [dnaleromj!~dnaleromj@98.124.126.110] has joined #linuxcnc-devel
[23:11:05] <seb_kuzminsky> what does "ls -l" of the problematic sysfs file say on those two kernels?
[23:14:32] <cpresser> i need to do one other thing first, ill come back with more info in ~30min
[23:20:17] -!- dnaleromj has quit [Ping timeout: 264 seconds]
[23:28:22] -!- syyl_ has quit [Ping timeout: 265 seconds]
[23:32:56] <jepler> also take a look at the output of ls -l /usr/bin/rtapi_app
[23:33:05] <jepler> just to double-check it's setuid root as expected
[23:33:59] <jepler> I don't think I've actually run uspace from a deb
[23:36:57] <PCW> preemt-rt ruins very well on the G3258 (26 usec latency is worst case I ever saw but rarely above 6 or so)
[23:37:24] <PCW> runs
[23:39:25] <seb_kuzminsky> installing linuxcnc-uspace.deb on wheezy autpomatically pulls in the rt-preempt kernel, that's all kinds of cool
[23:39:55] <PCW> plots of read time are almost flat (vs ~4 to 1 range of baseline vs peaks on a Atom)
[23:40:04] <jepler> seb_kuzminsky: buildbot front page should probably call out the paths for 2.7
[23:40:13] <seb_kuzminsky> err, yes
[23:40:28] <seb_kuzminsky> i'm gonna move things around a bit for 2.7
[23:40:49] <seb_kuzminsky> like i did on wlo already: 2.7-rtai and 2.7-uspace, compared to 2.6 (for rtai) and 2.6-sim
[23:42:21] <jepler> hmmm some people won't want an rt-preempt kernel just because they install linuxcnc
[23:42:26] <seb_kuzminsky> "apt-get install linuxcnc-uspace" works and pulls in the -rt kernel, and linuxcnc runs sim/axis/axis just fine (which is not the error cpresser reported)
[23:43:12] <seb_kuzminsky> then i reboot to the -rt kernel and linuxcnc still runs sim fine
[23:43:15] <seb_kuzminsky> that's kinda neat
[23:43:41] <PCW> does it do the grub futzing?
[23:43:46] <seb_kuzminsky> but it doesn't address cpresser's issue of permission problems on linux 3.14-rt
[23:43:55] <PCW> thats odd
[23:43:58] <seb_kuzminsky> PCW: yes, the -rt kernel shows up in the grub menu
[23:44:10] <seb_kuzminsky> bbl, bus stop
[23:44:20] <jepler> 1:2.7.0~pre2.17.g5f26871 installs rtapi_app with the expected permissions
[23:44:50] <jepler> and loads hm2_pci with the 3.2.0-4-rt-amd64 kernel
[23:45:03] <seb_kuzminsky> that agrees with cpresser's report
[23:45:07] <cpresser> it does have setuid here.. i am going to reboot the machine now.
[23:45:12] <jepler> now trying to find 3.14.15...bpo
[23:45:18] <seb_kuzminsky> the problem seems limited to the 3.14-rt kernel he got from backports
[23:45:37] <cpresser> jepler:
https://packages.debian.org/wheezy-backports/linux-image-3.14-0.bpo.2-rt-amd64
[23:45:50] <cpresser> you also need to get initramfs-tools from packports
[23:46:18] <jepler> hmm I enabled backports but the only bpo kernels I see are linux-image-3.16-0.bpo.2-amd64 and friends (no -rt since there's no 3.16 -rt)
[23:46:29] <jepler> deb
http://ftp.debian.org/debian wheezy-backports main
[23:48:29] postaL_offline is now known as postaL
[23:49:02] <cpresser> here is one difference:

[23:49:23] -!- pjm has quit [Read error: No route to host]
[23:49:40] <jepler> "enable" vs "enabled" ?
[23:49:57] <andypugh> Is there an elegant way to subtract pose tuples in python? I was rather hoping that (s.actual_position - s.g5x_offset) would “just work”
[23:50:06] <andypugh> (It would in Matlab :-)
[23:50:55] <jepler> andypugh: map(operator.__sub__, pos1, pos2)
[23:51:22] <cpresser> jepler: i only spottet the permissions, but yes, the filename also differs

[23:52:12] <jepler> if the linux people broke the userspace api of /sys then phooey on them
[23:52:48] <cpresser> hmm.. i should check if its even the same device.. bus numbering might differ between kernels.
[23:53:11] <jepler> "enable" is in the documentatation at
https://www.kernel.org/doc/Documentation/filesystems/sysfs-pci.txt so if that's gone and replaced by "enabled" then somebody will have to figure out what the deal is and modify linuxcnc
[23:54:20] <jepler> in 3.16-2-amd64 I also have no "enable", just "enabled"
[23:56:22] <andypugh> jepler: Hmm, that is certainly elegant, though I suspect I would have no idea what it did next time I looked at it. :-)
