[01:27:47] <seb_kuzminsky> jepler: f-engrave forked a GPL2 program named ttf2cxf
[01:28:13] <seb_kuzminsky> the gpl2 ttf2cxf code is included with the gpl3+ f-engrave source

[02:24:54] <cradek> jepler: the f-engrave package has a binary built from a 2-only source file and installed in /usr/bin, and also a separate 3+ python file installed into /usr/bin
[02:25:13] <cradek> they are packaged together but aren't a combined program
[02:25:52] <cradek> this has nothing to do with linuxcnc.git or combining with linuxcnc
[02:26:27] <seb_kuzminsky> yeah, the plan would be to build f-engrave's source into a separate deb, and publish that deb on wlo
[02:26:27] <cradek> jepler: [background] seb is packaging f-engrave, which is a cool program formerly with no useful packaging
[02:27:02] <seb_kuzminsky> and i jumped the gun and did it, damn the lawyers, full speed ahead! and now you can apt-get it from wlo
[02:27:21] <seb_kuzminsky> but maybe i have to take it off or split it up or something if i broke some law
[02:28:05] <seb_kuzminsky> oh, and Scorch, the author, declined my request to relicense the python program from GPL3+ to GPL2+, so it's on us to deal with somehow
[02:28:26] <cradek> hmm ok
[02:28:46] <cradek> worst case is you make two packages
[02:29:16] <seb_kuzminsky> yeah, and point the lawyers at Scorch's zip file if they come a-knockin
[02:29:39] <cradek> yes if there's a problem it'd be on him/her
[02:40:36] <jepler> ok thanks for the clarification.

[18:52:01] <PCW> puzzled by "clearpath servo" thread
[18:52:02] <PCW> I just cannot duplicate the following error no matter what I do
[18:52:04] <PCW> (but I have not tried rotary axis just their really high accel on linear axis)
[18:52:06] <PCW> Their setup is a bit weird (rotary axis accel is extreme = 8000 degrees/s^2 so 16 ms to full speed but linear axis are slow ~150 ms to full speed)
[18:58:15] <skunkworks_> the fact he is getting a following error - doesn't it point toward a tuning problem?
[18:58:56] <skunkworks_> stepgen<>motion?
[18:59:54] <PCW> Except I have tried the same numbers and see no problem (and even wildly different numbers) and cannot duplicate his large following errors
[19:01:46] <PCW> Tormach did have the thread order messed up but I think just about everything looks right now and its still broken
[19:01:56] <skunkworks_> With the same stepgen acc/vel overhead?
[19:02:08] <PCW> yes
[19:02:57] <PCW> I tried the same setup (8000 accel and 9600 stepgen accel and 125 velocities and see no issue at all)
[19:03:34] <PCW> (well other than the accel slope is in about 18 velocity steps)
[19:04:36] <skunkworks_> sim runs g1z3a3600f120 just fine with the rotory settings like his acc/vel
[19:05:19] <PCW> OK so I'm stumped
[19:05:20] <PCW> PathPilot bug?
[19:05:43] <skunkworks_> no clue - have not played with it yet.
[19:06:35] <PCW> Just making sure its not a stepgen/PID issue
[19:07:13] <PCW> pretty hard to debug without halscope
[19:09:07] <PCW> Their are definite issues with their hal file but this sort of looks like something else
[19:10:08] <skunkworks_> I am pretty sure pathpilot still has halscope. I think it is something like from mdi - admin halscope
[19:10:28] <PCW> I even had the guy look at the card jumpering sine the only way I could get that wild behavior is having a crazy wrong stepgen clock
[19:13:01] -!- md-2 has quit [Quit: Leaving...]
[19:15:08] <cradek> do you have the whole ini and hal config?
[19:16:38] <skunkworks_> http://forum.linuxcnc.org/forum/pathpilot/31037-pcnc770-4th-axis-w-clear-path-servo-pathpilot?limitstart=0#75368
[19:16:44] <skunkworks_> it is tormachafied
[19:17:38] <cradek> what happened to his FF1?
[19:17:38] <skunkworks_> I could setup a 7i90 config with those setting just to see. (it would be a good exersize.)
[19:18:00] <cradek> and I thought you told him to stop using MAX_ERROR
[19:19:10] <skunkworks_> further on he changes max_error - but I think you may have spotted it?
[19:19:18] <skunkworks_> FF1?
[19:19:28] <cradek> it was 1 on cnczone, now it's 0 which is surely wrong
[19:19:57] <cradek> oh I see page 2 now
[19:20:01] <cradek> grr forum
[19:20:08] <skunkworks_> in his paste - it is also missing ff1
[19:20:31] <cradek> yeah I bet he changed it mistakenly
[19:20:54] <skunkworks_> Do you want to post?
[19:23:43] <skunkworks_> Probably a silly question.. ;)
[19:25:25] <cradek> hey I even know my password
[19:25:27] <cradek> I'll post
[19:25:40] <skunkworks_> Great! Thanks for noticing that.

[20:01:36] <PCW> Thanks Cradek, maybe he's been changing one thing at a time and reverting the previous change...
[20:02:28] <cradek> it's so easy to get confused when trying a bunch of things (and so frustrating when helping someone when that happens)
[20:03:03] <cradek> it's good, now that he gets immediate ferrors when it's wrong
[20:07:19] <PCW> yeah much better than making things that are machined wrong
[20:10:34] <PCW> I have to remember to not have people set the stepgen FERROR limits too small
[20:10:36] <PCW> as that does not work without the DPLL (you need to add servothread jitter*maxvel without the DPLL)
[20:16:04] <PCW> I can get below about 200u degrees peak error with the DPLL and decent tuning (thats about 1/25 of a step in his setup)

https://lwn.net/Articles/689792/
[23:57:35] <andypugh> What are the chances of that?
[23:58:26] <andypugh> (actually not such a trivial computation, it’t the Birthday thing with an unknown sample size).
[23:59:21] <andypugh> ie, a class of 30 children is very likely to have two with the same birthday, because they already share a year, and 1 in 365 * the combinations is small
