[01:39:21] <jepler> I think that finishes off the errors I bumped into while working on this sserial thing
[01:40:55] <jepler> I *thought* that there was a sticky error that would persist after one session stopped sserial due to excess errors into the next session, but now I believe that was only due to my glitch-inducing still being active the next time I started realtime.
[01:44:15] <jepler> hm2/hm2_7i92.0: hm2_sserial_waitfor: Timeout (24mS) waiting for addr 5d1c &mask ff00 val 2000
[01:44:40] <jepler> this occurs >1 in 10 when I don't turn off the glitch before exiting halrun, and <1 in 20 when I do turn it off, so I think it's glitch-induced
[01:45:36] <jepler> ditto occasional non-detection when glitch is still enabled

[01:55:14] <PCW> I think a stop and start of sserial clears all memory so there should not be anything that's persistant
[01:56:06] <jepler> right, it was my left over 10kHz or whatever glitch train that was causing the problems
[01:56:50] <PCW> though if there is something that can cause a hang it would be good to know ( some of the previously fixed hangs were caused by errors during startup )
[01:56:54] <jepler> PCW: did you get a chance to try my branch / do you want to try it before it goes into the 2.7 branch
[01:57:01] <jepler> ?
[01:57:19] <PCW> I can try tommorow, pretty beat today
[01:57:31] <jepler> OK, that's fine by me
[01:57:44] <jepler> everything relevant is in branch jepler/2.7/hm2-sserial-faults
[01:58:15] <jepler> seb gave me a positive review, though I put a few more changes on top of that to fix the last error message that jt mentioned earlier
[01:58:28] <PCW> i have a physical error inducer ( Ethernet transformer in series with TX and RX with function gen )
[01:59:20] <PCW> i need to rebuild all bitfiles with the filtered UART also, need a faster machine
[01:59:24] <jepler> if you can trigger a remote fault in your testing, that would cover something I haven't been able to do
[02:00:01] <PCW> yeah is easy on 7I76.77,71,71,84
[02:00:14] <PCW> (just short an output to GND)
[02:01:12] <jepler> Ok, I'll look forward to hearing the result of your tests
[02:01:27] -!- justanotheruser has quit [Ping timeout: 250 seconds]
[02:01:33] <PCW> you could trigger a remote WD error by running your thread realllly slow
[02:02:24] <PCW> you would need to bump up the FPGA WD time
[02:03:10] <PCW> ( default remote WD time is 50 ms )
[02:03:30] <jepler> OK
[02:03:32] <jepler> hm2/hm2_7i92.0: Smart serial card hm2_7i92.0.7i69.0.7 error = (24) Watchdog Fault
[02:03:41] <jepler> yeah that works to trigger, but the message continually re-triggers
[02:03:49] <jepler> but now I can test it, so that's good!
[02:04:02] <PCW> forgot about the WD
[02:04:58] <jepler> oh wait I wasn't on the right branch
[02:05:11] <jepler> changing branches back to mine I get
[02:05:12] <jepler> hm2/hm2_7i92.0: Smart serial card hm2_7i92.0.7i69.0.7 error = (24) Watchdog Fault
[02:05:15] <jepler> hm2/hm2_7i92.0: Smart serial card hm2_7i92.0.7i69.0.7 error = (8) Remote fault
[02:05:18] <jepler> just once
[02:05:53] -!- becca_KB1WRP has quit [Quit: Leaving]
[02:06:38] <PCW> Ahh thats good ( wonder if a per channel hal flag would be the right thing for this)
[02:07:05] <jepler> I *think* the way I've coded it, it is one per channel
[02:07:14] <jepler> let me scare up another cat5 cable and see
[02:09:41] <jepler> yep it prints fault (24) and (8) for each of two channels

[02:27:58] <cradek> don't ask me, I'm barely a C programmer

[02:30:35] <jepler> oh "good" -- it fails on more than one platform
[02:31:16] <cradek> but I bet the change fixed the bug on dewey's platform; he doesn't push random untested stuff...
[02:32:04] <jepler> it builds on my jessie laptop
[02:32:31] <cradek> how do you even c++

[02:34:53] <jepler> checking whether g++ supports C++11 features with -std=c++0x... yes
[02:35:06] <jepler> this pair of configure lines is enough to tell me it's g++-4.6 and not -4.7 there, so mystery solved
[02:35:18] <jepler> it's a legitimate feature of C++11 not supported by old g++, so we'll have to work around it...

[04:06:58] <trentster> Hey guys - I was wondering if this is a known bug. If you look at my video at around 18:55 - you can see the Linuxcnc not showing cone or tool https://www.youtube.com/watch?v=swa-eX0irPg I Would love some help with this as it really bothers me! It does this regardless of gcode complexity - yet it does show the cone innitially when starting up and using the default linuxcnc gcode sample file. The display options of course have been set to alway

[04:36:49] <seb_kuzminsky> jepler: you can see what version of gcc it's using by looking at the environment-report step or the configure step
[04:42:15] -!- patricka_ has quit [Ping timeout: 240 seconds]
[04:53:43] <seb_kuzminsky> trentster: i see you're using a big machine and a small tool
[04:54:08] <seb_kuzminsky> are you sure you're not just so far zoomed out that your .125 inch diameter cutter becomes too small to see easily?
[04:54:45] <seb_kuzminsky> oh wait, you're in metric
[04:55:07] <seb_kuzminsky> so your tool diameter is .125 mm, that's a pretty small cylinder in the backplot...
[04:55:20] <seb_kuzminsky> do this experiment:
[04:55:51] <seb_kuzminsky> after your program is done, jog up so the tool is above the clutter of the tool path, and zoom in
[04:56:10] <seb_kuzminsky> might help to drive it to some easy-to-find location first, like the active coordinate system's origin
[04:57:39] <trentster> seb_kuzminsky: in this particular video its a big part, but it does not even show it when I cut smaller parts e.g. 60mm x 80mm in dimention
[04:57:54] <seb_kuzminsky> it looks like the tool diameter in your tool table does not match the tool in the spindle, so i'm going to assume you're not using cutter compensation in your program
[04:58:08] <seb_kuzminsky> thus the tool diameter is not used, and you could set it to something bigger, easier to see
[04:58:29] <seb_kuzminsky> 60x80 mm is still 600 times bigger than your programmed tool diameter
[05:00:11] <trentster> seb_kuzminsky: in that particular video it was default gcode output for linuxcnc postprocessor from Vectric aspire
[05:00:35] <trentster> As far as I know they dont use smoothing or cutter compensation
[05:00:52] <trentster> and in Linuxcnc the lookahead smoothing is active by default afaik
[05:01:02] <seb_kuzminsky> yep
[05:01:12] <seb_kuzminsky> i bet your tool diameter is just too small to see
[05:01:18] <trentster> it also does not show for me when I use gcode output from autodesk fusion 360 using smoothing and compensation
[05:01:50] <seb_kuzminsky> it's a feature of the tool table, not of your cam
[05:02:12] <seb_kuzminsky> try "g10 l10 p1 r50"
[05:02:41] <seb_kuzminsky> that says, "set tool diameter" (g10 l10) of tool 1 (p1) to 50mm (r50)
[05:03:40] <seb_kuzminsky> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g10-l10
[05:03:48] <seb_kuzminsky> ah, sorry, it's tool radius, not tool diameter
[05:05:55] <trentster> ok - let me go out to the garage and check up
[05:06:08] <trentster> I know I have put the radius in the tool table
[05:06:22] <trentster> I am using metric and have used 6 for 6mm etc
[05:07:07] <seb_kuzminsky> the video shows 0.125 for the radius
[05:07:12] <seb_kuzminsky> mm
[05:09:22] <trentster> yeah thats in that video, like I said the same thing happens every time regardless of tool used or part size
[05:09:40] <trentster> but I understand the video is your only reference source
[05:09:42] <seb_kuzminsky> .1mm is about the width of two human hairs side by side
[05:10:05] -!- knownasilya has quit [Quit: Connection closed for inactivity]
[05:10:10] <trentster> lol - yes I know
[05:10:13] <seb_kuzminsky> heh
[05:10:19] <seb_kuzminsky> i dont know what your other tools are like
[05:10:25] <trentster> perhaps it been put into tool table incorrectly. I will check and revert
[05:10:35] <trentster> thanks a ton for your help btw :-)
[05:10:49] <seb_kuzminsky> but i have a suspicion you're using a tool table that was preloaded with imperial tools
[05:11:00] <seb_kuzminsky> in fact the tlo of 0.511 looks familiar
[05:11:43] <seb_kuzminsky> sim/axis/sim.tbl:T1 P1 Z0.511 D0.125 ;1/8 end mill
[05:12:00] <seb_kuzminsky> it's the example tool table we ship with just about all our example configs
[05:12:14] <seb_kuzminsky> it's intended for imperial machines
[05:12:25] <trentster> seb_kuzminsky: yes that sounds like a plausible explanation.
[05:12:31] <trentster> How do I remedy that?
[05:12:52] <trentster> delete tool table and start with a clean one?
[05:13:49] <trentster> it would also explain why I see the cone for default linuxcnc gcode file that loads when gui opens as its in inches right
[05:14:07] <seb_kuzminsky> i'd recommend instead, in Axis, go to the File menu, select Edit Tool Table
[05:14:59] <trentster> ok going out be back in 5 or 10 minutes
[05:15:01] <seb_kuzminsky> the splash code runs without a tool
[05:15:08] <seb_kuzminsky> aka, with tool T0
[05:15:14] <trentster> yup
[05:15:19] <seb_kuzminsky> which shows up as a cone, because of reasons
[05:15:42] <seb_kuzminsky> ok
[05:15:51] <seb_kuzminsky> if i'm not still here in 5 or 10 minutes, i'll read back in the morning
[05:23:33] <trentster> seb_kuzminsky: ok you were right!
[05:24:07] <trentster> there were still default imperial tools in half of the tool table. duh! I feel so stupid
[05:24:13] <trentster> thanks for your help
[05:25:33] <seb_kuzminsky> welcome! i'm glad it's working right for you now :-)
[05:26:02] <seb_kuzminsky> that's a nice tutorial, it covers a lot of important stuff
[05:26:24] <trentster> ah thanks - its my first cnc one
[05:26:52] <trentster> I plan to do a couple more LinuxCNC related ones, I think there is a need for some newbie style videos
[05:27:33] <seb_kuzminsky> yeah there sure is
[05:27:40] <trentster> at least now I will have cones in the videos ;-)
[05:27:49] <seb_kuzminsky> :-)

[22:08:34] <mozmck> There needs to be a way to put up only one error when the 7i92 card gets disconnected.
[22:10:21] <mozmck> Right now I get an endless stream of notifications "Error Message" "hm2/hm2_7i92.0:error finishing read! iter=1856796"
[22:11:12] <jepler> I don't think hostmot2 in general has a way to deal with an entire lost hostmot2 card
[22:12:37] <jepler> it's somewhere on my stack of not started hm2_eth improvements to deal gracefully with small numbers of lost packets
[22:14:45] -!- Deejay has quit [Quit: bye]
[22:15:46] <jepler> dealing better with an unplugged or powered off card might fall out of that
[22:15:54] <mozmck> Hmm, I would be willing to work on that if I'm pointed in the right direction! In XFCE it seems the notifications (using gscreen) do not go away either - you have to click each one.
[22:17:58] <jepler> there's llio's io_error
[22:18:37] <jepler> one possibility is that hm2_eth should set it before returning with an error from its functions called by e.g., hm2_tram_read
[22:18:56] <jepler> just like 7i43 does
[22:18:56] <jepler> if (hm2_7i43_epp_check_for_timeout(board)) {
[22:18:56] <jepler> THIS_PRINT("EPP timeout on data cycle of read(addr=0x%04x, size=%d)\n", addr, size);
[22:18:59] <jepler> (*this->io_error) = 1;
[22:20:30] <jepler> that would fix the infinite spew of errors, but it might have to be undone as a first step of handling occasional missing ethernet packets..
[22:22:30] <mozmck> ok, I'll try and look at the code before long. thanks!
[22:23:38] <jepler> good luck! I'll review whatever you come up with, I am probably most familiar with that code atm
[22:24:04] <jepler> I can see it would be inconvenient to end up with 1000 operating system notification pop-ups every second :-/
