[00:00:15] <jepler> PCW: it's not table-driven, but I have the start of a d8 assembler in Python. http://emergent.unpythonic.net/files/sandbox/ada8.py some things that it does: http://pastebin.com/Acg7qkii
[00:00:55] <jepler> I think I don't know how indirection / offsetting works
[00:01:26] <PCW> wow thats impressive (and it has labels!)
[00:02:55] <PCW> Yeah
[00:02:56] <PCW> addtocb @y,17
[00:03:34] <jepler> how's that encoded? I see add is major opcode C ..
[00:04:10] <PCW> did you look at tasmd8s.tab
[00:04:24] <jepler> no, I'm trying to read d8o8.vhd!
[00:04:54] <PCW> thats the hard way!
[00:05:09] <kwallace> ssi: the roughing and finishing is a product of generating a g-code file and not done with canned g-code commands which would might be considered part of LinuxCNC.
[00:06:05] <jepler> PCW: where would I get this file tasmd8s.tab ?
[00:06:09] <PCW> d8o8sqws is the latest (d808 is obsolete)
[00:07:41] <PCW> its buried in the hostmot2 source distribution, let me dig it out

[00:12:01] <ssi> kwallace: what does it take as input? a gcode path, the way G70-type cycles do?

[00:26:51] <kwallace> ssi: We do use the G76 canned cycle for threading but generally I consider how I would want to do a basic type of machining operation, work out what parameters are needed, create entry boxes in Glade to enter these parameters, then write a Python script or .ngc file that couples the parameters to basic g-code commands and puts them in order.

[01:53:13] <ssi> kwallace: thanks, I'll poke around
[01:58:36] <skunkworks_> jepler: nice! so - it just couldn't handle the higher clock?
[02:00:02] <cradek> ssi: I suspect that's a consequence of the DISPLAY[GEOMETRY] setting
[02:00:10] -!- sirdancealot has quit [Ping timeout: 260 seconds]
[02:00:12] <cradek> err I mean [DISPLAY]GEOMETRY
[02:00:58] <cradek> ugh, which is not documented in http://linuxcnc.org/docs/html/gui/axis.html
[02:01:02] <cradek> weird
[02:01:04] <cradek> I was sure it was
[02:01:15] <skunkworks_> so was I...
[02:01:44] -!- swingley has quit [Ping timeout: 244 seconds]
[02:01:51] <cradek> oh it's in http://linuxcnc.org/docs/html/config/ini_config.html
[02:02:40] <cradek> > Geometry has no effect without a rotary axis.
[02:02:48] <cradek> it doesn't seem like that would be true
[02:03:17] <cradek> axis_foam has GEOMETRY = XY;UV which is not a thing that's documented
[02:08:33] -!- ravenlock has quit [Ping timeout: 240 seconds]
[02:08:34] <jepler> skunkworks_: I guess -- it's sold as a 1.7GHz device, so no wonder if running it at 2.0GHz doesn't work right
[02:09:31] <skunkworks_> heh - I had the same problem with the nook color.. you could overclock it to 1ghz - but mine seemed to run the best at the 800mhz spec
[02:10:46] <jepler> I dunno that you can really call it a "problem"
[02:11:02] <skunkworks_> right
[02:13:39] <ssi> cradek: any idea how that works with machines with multiple joints in an axis?
[02:13:57] <ssi> I'm guessing I'll need either XY or XYY
[02:13:59] <jepler> [DISPLAY]GEOMETRY takes no account of joints, it is based purely on axes
[02:14:03] <ssi> ok
[02:14:09] <ssi> I'll give it a shot
[02:14:31] <jepler> If GEOMETRY=XYY is accepted, it might show twice the Y displacement
[02:14:50] <ssi> if it defaults to the kins geometry string, that might explain my problem
[02:15:46] <jepler> a quick glance at the source suggests axis is only looking at [DISPLAY]GEOMETRY
[02:16:16] <cradek> gantry.ini:GEOMETRY = XYYZ
[02:16:17] <ssi> laser machine is shut down right now, but teh plasma machine has GEOMETRY = XYYZ
[02:16:22] <ssi> so yeah that's probably the issue
[02:16:23] <cradek> it's in our sample config

[02:16:45] <cradek> jepler: does it do something with ; ?
[02:17:02] <ssi> I'm pretty sure that fixed it :)
[02:17:04] <jepler> cradek: yes
[02:18:14] <jepler> cradek: though I don't immediately find where
[02:19:30] <ssi> that might be the last of my little bugs with the gantry machines!
[02:19:42] <jepler> oh I have been looking at 2.5
[02:20:14] <ssi> if i were a motivated, helpful individual, I would write up some sort of document explaining my findings on running dual-homing gantry machines with ja

[03:07:41] <jepler> clang 3.5 is about the same speed as gcc 4.6 on this arm
[03:07:55] <jepler> from time to time I read about how clang is faster than gcc, but I've never personally experienced it

[03:10:19] <cradek> iirc, coverity says halrmt is bad in lots of ways
[03:10:31] <jepler> clang scan-build has a litany of complaints too

[03:22:11] <mozmck> I've read a couple of articles indicating that the latest gcc is sometimes faster and generates faster code than clang.
[03:23:41] <jepler> I have found that gcc 4.6 is faster than 4.7, both on linuxcnc and $DAY_JOB
[03:23:50] <jepler> in neither case have I found clang faster than gcc 4.6.
[03:23:56] <mozmck> interesting
[03:24:05] <jepler> execution speed is not as important to me

[12:31:03] <jepler> Tom_itx: thanks, but not really. ghdl is used for building the .pin and .xml files, not for building the bitfile
[12:31:18] <jepler> also ppas don't help, that's ubuntu magic that doesn't work with debian
[12:31:24] <Tom_itx> ahh
[12:31:27] <jepler> thank though!
[12:31:28] <jepler> +s
[12:31:30] <Tom_itx> well i'm no linux guru :)
[12:33:48] <skunkworks> at what point do you stop saying that I wonder... (I am not a linux guru either)
[12:38:10] <skunkworks> btw - I had been having a problem with mdadm not assembling an array on boot. would have to stop it and reassemble it. Found #mdadm and had talked asked on there. really helpful folks (well one guy) it ended up being at some point replacing a drive I managed to get a super block on sdj and sdj1. (sdj1 was where it should have been) on boot it would try to assemble with sdj.
[12:39:05] <jepler> yuck
[12:39:08] <jepler> glad you worked it out
[12:39:22] <skunkworks> this has been a problem for atleast a year... :)
[12:39:48] <skunkworks> and when you only reboot the sever once in a blue moon - it is hard to rembmer what you did last time..
[12:39:54] <jepler> yup
[12:40:53] <jepler> a few years ago something along these lines happened to my home system while I was on vacation. I had to have cradek go to my place and talk him through a process I didn't remember for myself
[12:41:36] <jepler> speaking of which, I need to reboot this system. I don't think there are any such surprises waiting for me though

[15:40:07] <kwallace1> cradek, sorry I missed your reply. I am working on a routine to get tool heights from a tool setter. I call an O subroutine that calls for a probe move in -Z. While that is running, I have a check for a falling edge on is_probing in the UI periodic function. When the probe trips, I capture the position. I use the linuxcnc.status position, which is in machine or G53 space because the tool change messes up the .ngc probe capture G5x space.
[15:40:10] <ssi> seb_kuzminsky: +1 :D
[15:41:27] <jepler> hah, ghdl build-conflicts with itself
[15:42:13] <kwallace1> This works okay except I am now doing two probes, one on the down stroke a higher speed, then finish on the up stroke at low speed.
[15:43:07] <kwallace1> So I don't know which falling edge is the finish probe.
[15:43:19] <jepler> seb_kuzminsky: with any luck, if I get it to build on wheezy, it'd build on precise / trusty too
[15:44:17] <jepler> n'th time's the charm
[15:45:08] <cradek> kwallace1: can you recast your problem so you do it entirely in gcode? polling the probe with the gui has never been the intent of probing, and if you use probing's captured position it will be accurate to the exact servo cycle the probe tripped (or released)
[15:46:11] -!- skunkworks_ [skunkworks_!~chatzilla@68-115-41-210.static.eucl.wi.charter.com] has joined #linuxcnc-devel
[15:46:50] <cradek> G38.x -> use #5063 -> eventually do the appropriate G10 L10/L11
[15:47:18] <cradek> I also use two probes like you describe, for tool length sensing
[15:47:24] <jepler> # ghdl -r pinmaker_SVST4_4_48
[15:47:24] <jepler> /usr/lib/ghdl/bin/ghdl: compilation error
[15:47:28] <jepler> well that's unhelpful
[15:48:03] <cradek> kwallace1: here is the code from my desktop mill: http://pastie.org/9450769
[15:48:54] <kwallace1> cradek, the problem is that the g-code position is in the active work and tool space, which changes when the tool length or anything else changes. I end up chasing my tail trying to compensate for the state changes.
[15:49:03] <jepler> yay, it works (it was non-executable $TMPDIR biting me again)
[15:49:51] <cradek> kwallace1: G10 L11 is the built-in way to deal with that
[15:50:40] <cradek> http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G10-L11
[15:51:58] <cradek> kwallace1: notice my remap uses M73 then G20, so even if the program changes units it still works
[15:55:43] <kwallace1> I'll need to study this a while to get up to speed. Thank you for the help.
[15:55:59] <cradek> welcome

[16:01:32] <jepler> seb_kuzminsky: I now have ghdl working well enough on debian wheezy that it can make the .pin / .xml files for hostmot2
[16:03:27] <jepler> seb_kuzminsky: in case you get motivated to put ghdl in our deb repository, here's the source: http://emergent.unpythonic.net/ghdl
[16:03:51] <jepler> looks like it's needed for wheezy, precise, and would be needed for feisty if we ever climbed on that bandwagon.
[16:06:45] <seb_kuzminsky> i dont think you meant feisty
[16:06:49] <seb_kuzminsky> trusty?
[16:06:52] <jepler> sure, that one
[16:07:06] <jepler> derpy duckbill
[16:08:20] <seb_kuzminsky> thanks for modernizing ghdl, but i'm pretty unmotivated to mess with the hm2 buildslave at this point
[16:08:57] <jepler> yes, and I'm not suggesting you should move it to wheezy
[16:10:22] <jepler> but on general principle, it's good to wear down the barriers we can to other people building hostmot2-firmware
[16:13:15] <seb_kuzminsky> for sure
[16:13:33] <cradek> I suspect udev's MODE="666" is read as decimal because there's no leading 0
[16:15:21] <jepler> oops, where'd we write that?
[16:15:36] <cradek> the xhc rule
[16:15:36] <seb_kuzminsky> lots of files in /lib/udev/ have MODE="660", so i dont think so

[16:16:55] <seb_kuzminsky> i wish dgarr were here
[16:18:36] <cradek> I only see 3-digit MODEs in one file, 69-libmtp.rules, which is some usb soundcardy stuff
[16:20:34] <seb_kuzminsky> on precise i see non-0-starting MODEs in 40-flashrom.rules and 69-libmtp.rules
[16:20:43] <seb_kuzminsky> i bet you're right
[16:20:49] <cradek> laaaaame
[16:21:37] <jepler> udev manpage sure doesn't say what is required

[16:23:29] <jepler> well, I have a udev entry here for my phone
[16:23:35] <jepler> MODE="0660" and MODE="660" both worked the same
[16:23:55] <jepler> assuming .. do I have to restart udev after editing one of those files?
[16:24:02] <cradek> the docs say maybe
[16:24:33] <jepler> though I didn't see the original report, maybe the reporting user is on some other version of linux
[16:24:40] <cradek> it's wheezy
[16:24:49] <cradek> but I think that T is a smoking gun
[16:25:16] <seb_kuzminsky> dont know what OP is running, but dewey reproduced the problem on wheezy
[16:25:27] <cradek> although he didn't get exactly 1232 so maybe it gets masked automagically
[16:25:55] <cradek> uh he got 1664
[16:26:08] <cradek> I probably didn't correctly guess the problem
[16:27:50] <jepler> I get mode crw-rw---T+ both ways
[16:28:06] <jepler> + indicates extended file access controls which can be shown with getfacl
[16:28:28] <jepler> this ties in with console user stuff
[16:28:52] <jepler> the meat in the seat gets special permissions
[16:29:00] <cradek> his doesn't show T+
[16:29:07] <jepler> huh
[16:29:35] <jepler> with no matching entry at all, I get crw-rw-r-T+ for my device
[16:29:40] <jepler> it may be that some other udev rules are matching it
[16:29:41] <cradek> maybe his rule isn't even firing at all
[16:30:03] -!- larryone1 has quit [Ping timeout: 240 seconds]
[16:30:42] <seb_kuzminsky> this all reminds me that the shuttlexpress driver needs a udev rule too
[16:30:49] <seb_kuzminsky> that's a piece of hardware i actually have, so i can test it
[16:31:31] <jepler> is the user in group "users"?
[16:31:52] <cradek> no
[16:32:15] <cradek> which is why it may have worked until now, with the wrong mode
[16:34:42] <jepler> sticky bit is udev's hint to itself not to remove the device node when the underlying module is unloaded (why?) https://lists.debian.org/debian-user/2012/02/msg01273.html

[16:43:18] <cradek> it's weird if MODE is just broken
[16:43:20] <dgarr> so i think 90-xhc.rules will work on both debian-wheezy and ubuntu if group is changed to plugdev, any contrary opinion?
[16:43:23] <seb_kuzminsky> hi dgarr
[16:43:47] <seb_kuzminsky> we were just talking about the xhc-hb04 problem
[16:43:48] <jepler> dgarr: so the group that is requested sticks and the mode that is requested doesn't ?
[16:44:09] <seb_kuzminsky> jepler: that's the case in my udev rules testing here, on wheezy
[16:44:22] <dgarr> yes: crw-rw-r-T 1 root plugdev 189, 769 Aug 6 09:34 002
[16:44:30] <seb_kuzminsky> i can control the group but not the mode, using a rules file for my phone
[16:44:38] <cradek> that's very weird
[16:44:45] <jepler> dgarr: try moving 90-xhc.rules to 99-xhc.rules
[16:44:49] <jepler> and test again
[16:45:35] <dgarr> jepler: test by unplugging , mv 90 99; plug again?

[16:45:40] <jepler> dgarr: yes

[16:46:33] <jepler> MODE="0664"
[16:46:57] <seb_kuzminsky> heh, i just arrived at the same conclusion as jepler
[16:47:14] <seb_kuzminsky> making the rule sort last fixed things on my test system
[16:47:27] <jepler> my file was named 99android.rules all along, so its "MODE" stuck
[16:47:58] <seb_kuzminsky> and just to make cradek happy, MODE="666" and MODE="0666" both yield rw-rw-rw-

[16:48:40] <cradek> oh good. all is not crazy.
[16:49:10] <cradek> fwiw, I could also add the install user to group users
[16:49:14] <cradek> if that makes compatibility easier
[16:49:59] <dgarr> after mv,works (still plugdev): crw-rw-rwT 1 root plugdev 189, 770 Aug 6 09:48 003
[16:50:17] <seb_kuzminsky> a normal user on precise is part of plugdev but not users
[16:50:17] <jepler> I wonder if our rules file should go in /lib/udev/rules.d .. it depends whether you take the view that it's a configuration file or not, I guess
[16:50:26] <cradek> debian adduser doesn't put new users in group users (or anything)
[16:50:32] <jepler> seb_kuzminsky: does precise have 91-permissions.rules?
[16:50:36] <cradek> maybe plugdev is more right, then
[16:51:00] <seb_kuzminsky> GROUP="plugdev" seems right

[16:52:23] <memleak> what has been the recent problems in regards to glade? i recall a few days ago someone said something about it.
[16:52:48] <jepler> memleak: there are two different problems.
[16:53:09] <seb_kuzminsky> memleak: stepconf used gtk.Builder wrong and got different results on wheezy/precise and lucid
[16:53:12] <seb_kuzminsky> jepler fixed it
[16:53:38] <jepler> memleak: the other problem was that debian wheezy did not package a version of glade that could be used to modify the glade files in linuxcnc due to a version mismatch; we fixed that by packaging it
[16:54:23] <seb_kuzminsky> dgarr: would you rename the xhc rules file to 99- and fix the GROUP?

[23:23:02] <PCW> hmm i cant get the usb image to boot
[23:23:23] <skunkworks_> you wont.
[23:24:01] <skunkworks_> with the rtai - the usb don't work. so after a bit - the boot fails because the usb ports disapear in linux.
[23:24:30] <skunkworks_> I used a dvd for the inital install - then installed the rt_preempt which works with the usb's

[23:26:26] <PCW> well thats a bit awkward :-(
[23:26:58] <PCW> I guess normal wheezy would install
[23:27:17] <PCW> and the rest could done from source
[23:29:03] <PCW> I guess that how i did the ubuntu install (usb boot from 12.04 then install the rest)

[23:49:38] <jepler> PCW: the 7i90hd manual will have details on how spi communication works?

[23:50:47] <PCW> Yes
[23:51:19] <jepler> PCW: I see it's also called "LBP16", I take it it's similar to the ethernet

[23:52:22] <PCW> lbp16 is the hm2 over serial interface (basically the same as ethernet)
