[03:14:33] <CaptHindsight> bad latency with Mint-debian and Mint 17 Qiana Xfce that uses the Trusty repos with the 3.4.55 RTAI and the debs for Precise
[03:15:18] <CaptHindsight> Linuxcnc debs for precise
[03:22:27] <skunkworks_> I have had pretty good luck so far with the wheezy setup. (one computer so far that doesn't play nice with the new kernel - 10.04 gives 10us vs 50+us on wheezy)
[03:36:54] -!- anarchos has quit [Ping timeout: 255 seconds]
[03:41:14] <seb_kuzminsky> skunkworks_: can you try the precise rtai kernel (3.4.55-rtai-2)? as far as i know that's still the best one
[03:42:08] zz_prtksxna is now known as prtksxna
[03:43:57] <skunkworks_> sure. what is on the wheezy cd?
[03:51:33] -!- pjm has quit [Ping timeout: 240 seconds]
[03:51:34] <seb_kuzminsky> something newer, probably 3.4.87-1~linuxcnc1
[03:51:56] <seb_kuzminsky> you can add precise as an apt source and manually downgrade the kernel
[03:52:30] <seb_kuzminsky> i'm wondering how its latency compares to the 2.6.32 rtai kernel in our lucid repo
[03:54:02] <CaptHindsight> 4 installs and tests today
[03:55:02] -!- djinni` has quit [Excess Flood]
[03:58:57] <skunkworks_> systems that run 50+us latency usually run a lot better - <20us when using 'idle=poll' in the kernel line..
[03:59:13] <skunkworks_> but it didn't seem to help the problem motherboard
[04:00:52] <skunkworks_> it even seems to help the preempt kernel
[04:01:04] <CaptHindsight> this asrock fm288m-hd+ and A6 6400K (dual core 3.9GHz) runs <7K on 10.04 with the 2.6.32 RTAI
[04:02:47] <CaptHindsight> on Ubuntu Precise 12.04 and 3.4.55 it runs about the same and if I add remove the irq balance it's down ~3K
[04:04:35] <CaptHindsight> so I'm stuck with precise or gentoo on this for now if I need fast video
[04:06:13] <CaptHindsight> if we spent enough time on Debian (learning the ins and outs) it might work well to

[04:16:27] <seb_kuzminsky> CaptHindsight: thanks for that report, it's helpful
[04:17:27] <seb_kuzminsky> the 3.4.55 and 3.4.87 rtai kernels have quite different rtai kernel patches, i'm thinking we get generally better results with the rtai kernel patch i used in the 3.4.55 kernel
[04:18:09] <CaptHindsight> I'm installing precise on it again right now (ran out of drive space)
[04:18:36] <CaptHindsight> I can try the 3.4.87 RTAI on it tomorrow
[04:19:51] <CaptHindsight> somebody else posted this board about month ago on the linuxcnc latency page
[04:20:30] <CaptHindsight> they had a different cpu, AMD A4-4000 Dual Core 3.2GHZ Max Turbo, 3.0 GHZ Base,
[04:21:12] <CaptHindsight> All Power saving features disabled in BIOS, Bios updated to VER 2.40, ISOLCPUS Enabled, IRQBalance un-installed, Disabled/Turned? Off spread spectrum, turbo core, APM, C6, cool'n'quiet, SVM, cpu throttle, suspend to RAM with latency 7966 on the 25uS thread

[14:07:56] <seb_kuzminsky> speaking of bad hygiene, i've build a new kernel with the "known-best" 3.4.55 rtai patch
[14:08:03] <cradek> yay
[14:08:12] <seb_kuzminsky> i'm gonna build rtai-modules for it, should be ready later this morning
[14:08:16] <jepler> Hopefully sourceforge gets a femtocent everytime it attaches a blurb about some proprietary software on our mailing list about free software.
[14:08:37] <seb_kuzminsky> then i should try it on my computer that crashes with the newer kernel patches when i plug in the wifi usb dongle
[14:08:45] <seb_kuzminsky> and i'd like dgarr to try it on his misbehaving machine
[14:08:46] <cradek> seb_kuzminsky: cool, will you also rebuild wlo/wheezy/2.6?
[14:09:03] <cradek> ah yes, basic testing should come first
[14:09:17] <cradek> I'm all ready to make a new cd image, but why bother unless we know it's better
[14:09:27] <seb_kuzminsky> and if it looks like it's a good kernel i'll push it to wlo, update the buildslave, rebuild 2.6, you can make a new cd image, and then we can finally release 2.6...
[14:09:43] <JT-Shop> on the CD image can you turn off the OS updates prompt?
[14:09:54] <cradek> seb_kuzminsky: so excited
[14:10:11] * seb_kuzminsky goes squeeee
[14:10:25] <cradek> JT-Shop: good question. I am not sure if there's any auto popup thing at all, I will figure it out
[14:10:47] <cradek> I think debian doesn't do the nag-you-to-push-the-button dist upgrade

[14:11:11] <JT-Shop> in the synaptic package manager > settings > repositories > Updates tab you can turn it off
[14:11:16] <skunkworks> I have not seen it with wheezy either..
[14:11:27] <JT-Shop> I don't know if that will be used when you make the CD or not
[14:12:16] <cradek> I would like it if there was the upgrade notice, but not one that changes the sources
[14:12:25] <skunkworks> I probably won't be able to test the kernel on wonky hardware until the end of the week
[14:12:39] <JT-Shop> the next CD will not be Ubuntu?
[14:13:12] <cradek> the one I am building is based on debian wheezy, which is the parent of ubuntu
[14:13:21] <JT-Shop> ah ok
[14:13:26] <jepler> hah, in debian 7 "wheezy", synaptic settings > repositories > updates, an option has the title "Notify me of a new Ubuntu version"
[14:13:29] <jepler> oops
[14:13:44] <cradek> that's very funny
[14:15:10] <skunkworks> wheezy is more similar in look and feel to 10.04 than ubuntu 12.04/14.04 with the selected desktop
[14:15:35] <JT-Shop> that's nice, I didn't care for the 12.04 desktop when I tried it

[14:26:31] <cradek> jepler: I set those things in synaptic but nothing happens when I reboot. there must be another xfce piece of the puzzle.
[14:27:14] <jepler> bugs.debian.org/710565
[14:27:45] <jepler> looks like gnome broke the update manager so that it doesn't work in xfce?
[14:28:17] <cradek> fff
[14:29:11] <jepler> do you still live in the fantasy land where it's possible to write an application like "show a list of available updates on the screen" that can work on more than one desktop environment?
[14:29:17] <jepler> give up and smell the coffee of the new gnome
[14:30:03] <jepler> (It's written "gnome" but a growing fraction of people pronounce it as "f--- those guys")
[14:32:42] <cradek> might work in wheezy? I installed update-notifier and am rebooting.
[14:34:21] <cradek> ugh
[14:34:23] <cradek> well it runs
[14:34:31] <cradek> but it constantly asks me for the "administrative" password
[14:34:46] <cradek> so it doesn't work with sudo
[14:36:07] <jepler> just to list the updates?
[14:36:27] <jepler> apt-get --dry-run dist-upgrade runs without root
[14:36:45] <cradek> it shows the number of available updates
[14:37:00] <cradek> when you click it to see/install them, it wants the password, and there isn't one

[15:11:06] <maximilian_h> using 2.6 pre4
[15:11:21] <maximilian_h> is anybody actually using this with a gantry ?
[15:22:34] <seb_kuzminsky> jmk speaks my language
[15:22:52] <seb_kuzminsky> maximilian_h: i've never setup or run a machine like that
[15:28:15] <maximilian_h> seb_kuzminsky: It is a samplemaking plotter for carton samples
[15:28:26] <maximilian_h> x and y is a flat table
[15:28:48] <maximilian_h> z is there for the height of the different tools
[15:29:32] <maximilian_h> and c is there because when you cut carton with any type of knife, or if you crease carton, when you need C around Z
[15:29:49] <maximilian_h> and X has a gantry setup on that machine
[15:30:34] <seb_kuzminsky> sounds like a neat machine!
[15:30:42] <maximilian_h> it is
[15:30:48] <maximilian_h> when it is working
[15:31:17] <maximilian_h> linuxcnc should be a replacement for an older msdos based controller

[15:37:58] <seb_kuzminsky> i dont know of anyone running a gantry with a rotary axis, that may uncover new issues
[15:38:30] <seb_kuzminsky> maximilian_h: there's some stuff on our wiki that may be helpful:

http://highlab.com/~seb/linuxcnc/rtai-debs (wheezy|precise) main
[15:41:22] <maximilian_h> seb_kuzminsky: thanks for these two links, I was aware of the gantry with the plasma, but the other one is new to me
[15:41:29] <seb_kuzminsky> the linux-image is 3.4.55-1linuxcnc, the rtai-modules is 3.9.260.g6394e67, these are probably downgrades for you
[15:41:39] <seb_kuzminsky> maximilian_h: i just searched for "gantry" on the wiki
[15:41:50] <seb_kuzminsky> i thought we had a page somewhere with known gantry wrinkles, but i couldnt find it
[15:42:27] <maximilian_h> my rotary axis it can jog with the right velocity
[15:43:05] <maximilian_h> but if I to a move like g90c0c3600 then it is so slow than I can hardly see it move
[15:43:46] <maximilian_h> with trivkins on a similar older machine without the gantry that worked just fine
[15:44:26] <maximilian_h> so it must be connected to either the gantry setup and/or the different joint numbers used
[15:44:32] <cradek> maximilian_h: c0c3600 does not make sense
[15:44:50] <maximilian_h> on the gantry i am using X with joints 1 and 2
[15:45:10] <maximilian_h> oh sorry, that should be g90g0c3600
[15:45:20] <maximilian_h> for 10 revolutions of the c axis
[15:46:06] <maximilian_h> when jogging that turns with the intended high velocity
[15:46:08] <cradek> you do realize F is in degrees/minute when you move only C axis, right?
[15:46:15] <cradek> if in G94 mode
[15:46:43] <cradek> this probably has nothing to do with gantry
[15:46:45] <seb_kuzminsky> for g0 that shouldnt matter
[15:46:52] <cradek> oh right
[15:47:00] <maximilian_h> I tried F5000 and F20000 too
[15:47:08] <maximilian_h> and it did not change anything
[15:47:10] <maximilian_h> yes g0
[15:47:25] <cradek> I bet this is an ini config thing then
[15:47:33] <cradek> (still not a gantry thing)
[15:47:38] <maximilian_h> I use g0c3600 or g0c36000 to calibrate the INPUT_SCALE for the C axis
[15:47:45] <maximilian_h> because of the gears used
[15:47:51] <seb_kuzminsky> have you looked at [DISPLAY]DEFAULT_ANGULAR_VELOCITY and friends in the ini file (assuming you're using the Axis gui)?
http://www.linuxcnc.org/docs/2.6/html/config/ini_config.html#sub:DISPLAY-section
[15:48:11] <maximilian_h> hang on, can I copy&paste my c axis here ?
[15:48:15] <seb_kuzminsky> hm, it says those are just for jogs, and i dont see an ini setting in [TRAJ] for angular velocity
[15:48:21] <seb_kuzminsky> maximilian_h: no! put it on pastebin
[15:49:14] <maximilian_h> hang on, I put it on pastebin
[15:49:46] <skunkworks> seb_kuzminsky, so - what exactly do I need?
[15:50:10] <skunkworks> (which debs)
[15:51:38] <skunkworks> there sure are alot in that directory ;)
[15:52:11] <maximilian_h> http://pastebin.com/bpXHsE1T
[15:52:17] <seb_kuzminsky> skunkworks: yeah, grab these:
[15:52:18] <maximilian_h> this is the pastebin
[15:52:30] <jepler> seb_kuzminsky: is there a timestamp in hostmot2?
[15:52:37] <seb_kuzminsky> rtai-modules-3.4-9-rtai-686-pae_3.9.260.g6394e67_i386.deb

[15:53:05] <seb_kuzminsky> that should do it to see if it runs and see what the latency numbers are
[15:53:14] <seb_kuzminsky> then also grab these if you want to build linuxcnc:
[15:53:26] <seb_kuzminsky> linux-headers-3.4-9-rtai-686-pae_3.4.55-1linuxcnc_i386.deb

[15:53:39] <seb_kuzminsky> i think that should do it
[15:53:51] <skunkworks> exactly what I needed - thanks
[15:53:59] <seb_kuzminsky> jepler: i dont know what you're asking
[15:54:15] <skunkworks> will the installed version of linuxcnc on the livecd work with the different kernel?
[15:54:22] <skunkworks> (wheezy)
[15:54:31] <cradek> nope
[15:54:33] <skunkworks> ok
[15:54:39] <jepler> seb_kuzminsky: Is there a free-running counter that counts up at a known speed?
[15:54:43] <seb_kuzminsky> ah
[15:54:45] <skunkworks> so if I want to run latency-test - I need to build rip
[15:54:48] <seb_kuzminsky> hm
[15:54:56] <seb_kuzminsky> skunkworks: you could run the rtai latency test
[15:55:01] <seb_kuzminsky> jepler: i dont know
[15:55:07] <seb_kuzminsky> PCW: do you know of one?
[15:55:10] <skunkworks> seb_kuzminsky, sure. ok.
[15:55:36] <seb_kuzminsky> maximilian_h: your C max vel is 660 degrees per minute, is that maybe the low speed you're seeing?
[15:55:58] <maximilian_h> no, I am seeing a vel of 60 in axis
[15:56:15] <maximilian_h> and I do not know where it is coming from
[15:56:45] <maximilian_h> axis as in axis, the gui
[15:56:47] <jepler> hm, there's this in regmap: 0x3300 TSCount 16 bit time stamp counter (read only)
[15:57:03] <jepler> 16 bits isn't much
[15:57:22] <seb_kuzminsky> doesn't the axis gui show vel in units/second mode, rather than units/minute?
[15:57:42] <jepler> (not if you wanted to replace rdtsc with a read of this register, when you have a pci hostmot2 board available)
[15:58:04] <maximilian_h> if it were in machine units per second
[15:58:16] <maximilian_h> then 60 degrees per second would be visible

[15:58:31] <maximilian_h> however when I look at the machine
[15:58:45] <maximilian_h> than I can hardly see any change because it is sooo slow
[15:58:46] <seb_kuzminsky> try adding a [DISPLAY]DEFAULT_ANGULAR_VELOCITY
[15:59:08] <seb_kuzminsky> i really dont know what i'm doing here, sorry! never used or configured a rotary axis
[15:59:39] <cradek> maximilian_h: you might want to look at sim/axis/axis_9axis.ini as an example of correct configuration
[15:59:52] <maximilian_h> I just know that on a similar machine without the gantry these settings do work for a rotary axis
[15:59:54] <cradek> maximilian_h: there are a lot of velocity and acceleration settings :-/
[16:00:30] <maximilian_h> yes, there are. I do want my autoengineer button to automagically setup everything ;)

[16:09:20] <seb_kuzminsky> yeah
[16:09:34] <seb_kuzminsky> i guess i'm doing something wrong with the packaging, but i'm not sure what
[16:10:22] <skunkworks> seb_kuzminsky, awesome ascii art!
[16:10:42] <skunkworks> I use a similar setup for offsetting Z based on spindle temp.. works great

[16:12:04] <cradek> it's minor
[16:12:23] <cradek> the timestamp does tell us the difference, but it's stupider
[16:12:30] <cradek> I didn't even notice it as important information
[16:12:43] <skunkworks> well - sorry to tell you this.. I don't think you are ready to do ascii art full time...
[16:12:56] <seb_kuzminsky> aww, guess i'll keep hacking then
[16:13:23] <seb_kuzminsky> you guys remember aalib? it was an ascii art backend for some graphics abstraction layer back in the 90s
[16:13:31] <seb_kuzminsky> you could run text-mode screen savers and things

[16:16:05] <cradek> email him?

http://www.panix.com/~dgarrett/stuff/07jul14.txt (amd machine, similar Oops)
[21:17:08] <cradek> jepler's suggestion was that we fix rtai to not break on this hardware
[21:17:25] <cradek> it's not a kernel version problem
[21:17:35] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[21:17:43] <seb_kuzminsky> dgarr: thanks for that
[21:18:02] <seb_kuzminsky> dgarr: can you confirm/deny that the old 3.4.55 kernel worked on that hardware (it had a different version of the rtai patch)
[21:18:47] <dgarr> what i remember is thre 3.4.55 kernel i tried earlier the ps/2 mouse did not work and i stopped at that
[21:18:55] <seb_kuzminsky> hmm
[21:19:23] <seb_kuzminsky> ok, last night i built new kernel debs with the 3.4.55 kernel and the old rtai patch, but a new kernel config that should have working ps/2
[21:19:43] <seb_kuzminsky> i sent you the link, can you try it if possible & report back?
[21:19:53] <seb_kuzminsky> i have high hopes
[21:20:04] <dgarr> i am reporting based on that link
[21:20:20] <dgarr> please make sure my log info confirms i am doing it correctly
[21:20:28] <seb_kuzminsky> the installed linux-image version in the page you just linked above says 3.4.87
[21:22:37] <dgarr> so i need to download a deb instead of using synaptic?
[21:23:03] <cradek> the problem may be that it's actually a downgrade in version number
[21:23:15] <seb_kuzminsky> i think you can do it with synaptic, but you need to add that "deb
http://highlab.com..." line to your sources.list
[21:23:26] <cradek> I used apt-get to install it, after fixing sources.list, and uninstalling the old one
[21:23:49] <cradek> I rebooted to a non-rtai kernel and uninstalled all the rtai kernel packages and rtai-modules
[21:23:50] <seb_kuzminsky> cradek: that's how i usually do it too
[21:23:56] <dgarr> i have deb
http://highlab.com/~seb/linuxcnc/rtai-debs wheezy main
[21:24:03] <seb_kuzminsky> that's good
[21:24:26] <seb_kuzminsky> what kernels do you have installed? look in /boot or "dpkg -l 'linux-image*' | grep ^ii"
[21:25:27] <dgarr> i just reloaded in synaptic, it only shows 87
[21:25:40] <seb_kuzminsky> ok, cool
[21:26:07] <seb_kuzminsky> in a terminal, run 'apt-get update'
[21:26:09] <dgarr> am i supposed to install the 3.4.96 ones? i can try that with the debs
[21:26:26] <seb_kuzminsky> you see the .96 ones?
[21:27:04] <seb_kuzminsky> they shouldn't be available any more, i removed them when they crashed my problematic test machine
[21:27:29] <seb_kuzminsky> you should see linux-image-3.4-9-rtai-686-pae with version 3.4.55-1linuxcnc
[21:27:35] <seb_kuzminsky> that's the one i'd like you to test
[21:27:48] <dgarr> i've done the apt-get update several times 96 doesn't appear, i am using /etc/apt/sources.list.d/linuxcnc.list
[21:28:00] <seb_kuzminsky> after the 'apt-get update', try 'apt-cache policy linux-image-3.4-9-rtai-686-pae'
[21:28:08] <seb_kuzminsky> you should see 3.4.87 and 3.4.55
[21:28:21] <seb_kuzminsky> with the 3.4.87 one marked as installed
[21:28:50] <seb_kuzminsky> then say "apt-get install linux-image-3.4-9-rtai-686-pae=3.4.55-1linuxcnc"
[21:29:04] <seb_kuzminsky> it'll complain about downgrading the package and about uninstalling the running kernel, but i think it should work
[21:30:18] <dgarr> apt-cache policy shows 3.4.55-1linuxcnc 0 -- i guess i don't know how to install it
[21:30:36] <seb_kuzminsky> dgarr: the "apt-get install" line above should do it ^^^^^
[21:32:08] <dgarr> ok that started, will i need any other updates like headers to build linuxcnc?
[21:32:44] <seb_kuzminsky> yes, although you can crash the machine by just running the rtai latency test, right?
[21:35:06] <dgarr> i wouldn't call it a crash but /usr/realtime*/testsuite/kern/latency/run hasn't worked yet with 3.4.x kernels seems a good indicator of linuxcnc problem
[21:35:21] <dgarr> i'll reboot that machine and try the testsuite latency
[21:35:25] <seb_kuzminsky> thank you
[21:39:20] <seb_kuzminsky> hmm, my kernel config changes didn't work in the 3.4.55 image :-(

[21:46:11] <cradek> haha
[21:46:14] <dgarr> i did the apt-get install rtai-modules... and it says: rtai-modules-3.4-9-rtai-686-pae is already the newest version
[21:46:21] <seb_kuzminsky> hrm
[21:46:29] * seb_kuzminsky sighs
[21:46:37] <seb_kuzminsky> i might have reused the version number by mistake

[21:51:52] <seb_kuzminsky> the versions of rtai that i'm trying to package all have different kinds of problems, so i'm having to jump around in their git tree to try to find something that works, and that makes for non-intuitive version numbers
[21:52:18] <seb_kuzminsky> once we find something that's good i'll remove all the broken ones we've tried and it'll be much more straight-forward frmo there

[22:02:37] <jepler> hm, I seem to be hitting a bug. I wonder if it's uspace or hm2_eth.
[22:02:50] <jepler> pin 7 is listed as a GPIO, and I've set its .is_output to true
[22:03:11] <jepler> setting .out to 1 or 0 doesn't change the attached blinkenlight, but setting .invert_output to 1 or 0 does
[22:03:48] <micges-dev> what board what bitfile?
[22:04:40] <jepler> micges-dev: 7i80, whatever bitfile was on it when shipped
[22:05:08] <micges-dev> check sticker on board
[22:05:14] <jepler> I see that the invert is actually separate from the gpio output
[22:06:00] <jepler> no sticker seems to identify the firmware.
[22:07:02] -!- lyzidiamond has quit [Read error: Connection reset by peer]

[22:21:26] <skunkworks_> jepler: if you just have an led plugged in - it will be lit...
[22:22:03] <skunkworks_> setting the gpio to open collector makes it act correctly
[22:23:57] <jepler> skunkworks_: this is one of those 7i31 daughterboards with a pile of LEDs
[22:24:13] <jepler> the LEDs will toggle on/off if I change the .invert_output of the (should be) GPIO

[22:59:42] <seb_kuzminsky> bizarre
[23:00:19] <dgarr> ok i just downloaded the deb and used dpkg to install it and the testsuite latency test works
[23:00:37] <dgarr> this is why i thing working from debs is easier than apt -stuff
[23:01:31] <seb_kuzminsky> oh!
[23:01:33] <seb_kuzminsky> wow
[23:01:42] <seb_kuzminsky> and it didnt crash or anything? that's new right?
[23:02:25] <seb_kuzminsky> your machine can run the 3.4.55-1linuxcnc ltency test, whereas it couldnt run the 3.4.87 or the 3.4.96 ones without crashing?
[23:02:28] <dgarr> this is first time testsuite latency test works

[23:05:01] <PCW> maybe pretty sure I'm running 32 bits
[23:05:13] <dgarr> so the testsuite latency started, i try linuxcnc ../configs/sim/axis/axis.ini and get

[23:05:43] <seb_kuzminsky> you'll have to use your wget-fu (or apt) to get the matching linux-headers, and recompile linuxcnc, and then i bet it'll work
[23:06:09] <seb_kuzminsky> btw i checked the web server logs and i never saw you download rtai-modules via apt-get, so i dont think the 'apt-get install --reinstall' did what i hoped it would
[23:06:14] <seb_kuzminsky> i saw you get it with wget though
[23:06:23] <seb_kuzminsky> you are 184.101.147.237, right?
[23:06:44] <dgarr> ..237 yes

[23:08:19] <seb_kuzminsky> oh well, shrug
[23:08:28] <micges-dev> PCW: duplicated from jepler's setup?
[23:08:44] <cradek> yayyy
[23:09:15] <seb_kuzminsky> i'll try it on my troubled machine at home tonight, and we'll keep our eyes open for new failures with this kernel, but i got a good feeling about this
[23:09:38] <seb_kuzminsky> and cradek, i think i fixed the uname bug you reported
[23:09:43] <cradek> that's terrific
[23:09:51] <cradek> let me know when I can rebuild the live image
[23:09:58] <cradek> that sure makes it easy for me to test hardware I see laying around
[23:10:05] <seb_kuzminsky> building a new one one, it only takes ~ 1e20 hours
[23:10:08] <jepler> if I don't turn up something here, I'll get a 32-bit install and see if that "fixes" it
[23:10:24] <PCW> micges-dev: same hardware and config (different OS though)
[23:10:33] <micges-dev> ok
[23:10:43] <cradek> jepler: oh I see you have a new problem - hmm
[23:11:39] <jepler> cradek: it's nothing to do with the rtai stuff
[23:12:03] <micges-dev> PCW: --readhmid was detecting latest pins configuration properly from about may, only up to now mf had problem with pins with sec_tag == 0
[23:12:15] <PCW> I guess it could be some weird hal file issue
[23:12:17] <PCW> I used hm2-servo.hal and a ini file with just num-encoders=6 (and the appropriate ethernet foo)
[23:12:17] <micges-dev> PCW: already fixed in repo
[23:12:51] <cradek> jepler: oh good
