[00:03:37] <tinkerer> btw, what do you think about refining and including my websocket example in lcnc?
https://github.com/tinkercnc/LinuxCNC2Websocket . Not necessarily my version but a similar one.
[00:06:47] <tinkerer> for justifying the web server (apache) dependency. ;)
[00:07:01] <jepler> it does not speak to any need I have personally.
[00:08:31] <jepler> This looks like software that depends only on public and fairly stable Python APIs in LinuxCNC, so I would say: yay, there's nothing forcing this to live inside linuxcnc.git, it is totally useful to keep in its own git repository
[00:08:46] <jepler> you can enhance and improve it without tying your development schedule to linuxcnc's
[00:09:38] <jepler> and if there's some way linuxcnc.org should be involved with how your users get this software, it's by working on the technical barriers that prevent it from being a package in the linuxcnc.org debian package server that simply depends on linuxcnc | linuxcnc-uspace
[00:12:13] <tinkerer> ok, but my intention was merely to take the 1st little step to web gui.
[00:12:45] <jepler> I hope you've enjoyed it as a learning experience, then.
[00:13:17] <tinkerer> and improving the nml <-> websocket interface

[14:01:34] <cradek> yay!!
[14:02:15] <seb_kuzminsky> :-)
[14:02:27] <skunkworks> is that the last one for 2.6?
[14:02:49] <seb_kuzminsky> that's the final 2.6 release, barring special circumstances
[14:03:19] <seb_kuzminsky> the release announcement will say so, and i'll encourage everyone to move to 2.7 if they want future updates
[14:03:32] <skunkworks> Yay!
[14:03:42] <seb_kuzminsky> i plan to make another 2.7 release in the next few days or week or so
[14:04:47] <seb_kuzminsky> mozmck: i updated the ReleaseCheckList wiki page with another one of the git commands i use to help make releases, but there's probably a lot missing still
[14:04:51] <seb_kuzminsky> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ReleaseCheckList
[14:14:57] <seb_kuzminsky> does the beginning of this page look weird to anyone else?
http://linuxcnc.org/docs/2.7/html/getting-started/updating-linuxcnc.html
[14:15:21] <seb_kuzminsky> it's supposed to be a document about upgrading from 2.6 to 2.7, but it starts out talking about upgrading from one 2.7.x to another 2.7.y release
[14:16:30] <archivist> title does not entirely match that intention either
[14:17:37] <seb_kuzminsky> the somewhat recent commit aee5df19c2 redid the opening this way, that i'm just now noticing
[14:18:10] <seb_kuzminsky> JT-Shop: what do you think about this?
[14:18:11] <seb_kuzminsky> bbl
[14:39:22] <JT-Shop> yea, updating is wrong, upgrading is better, I'll take a look at it in the morning gotta go to the industrial park for a while and work

[14:42:13] <seb_kuzminsky> i dont mind the updating/upgrading difference so much, those words are similar enough in meaning that it doesn't matter imo
[14:42:54] <seb_kuzminsky> it's the confusion between "upgrading between stable branches like 2.6 to 2.7" vs "upgrading within a stable branche like 2.7.0 to 2.7.1" that's bugging me
[14:43:53] -!- CaptHindsight [CaptHindsight!~2020@unaffiliated/capthindsight] has joined #linuxcnc-devel
[14:45:52] <JT-Shop> yep the latter should be getting maintenance releases or something like that
[14:46:02] <JT-Shop> bbl
[14:59:46] <seb_kuzminsky> JT-Shop: right, and 2.7.0 -> 2.7.1 upgrades should never have to care about adding apt sources or changing ini files or any of the other things that that document describes

[20:38:22] <seb_kuzminsky> hi zhivko
[20:38:44] <zhivko> hi seb
[20:39:22] <zhivko> I wanted to ask you about combination move translation and rotation - in g93 (inverse time mode)
[20:39:49] <seb_kuzminsky> ok
[20:40:09] <zhivko> I was told in #linuxcnc that any combined move including rotation will result in 1 segment look ahead - is this right?
[20:40:40] <seb_kuzminsky> i don't know for sure, but i'd expect lookahead is unaffected by rotation
[20:41:06] <cradek> yes moves that are not pure-xyz use the 2.6 planner
[20:41:08] <seb_kuzminsky> oh wait, by "rotation" you mean moving an angular axis like a, b, or c? not coordinate system rotation?
[20:41:17] <zhivko> yes exactly...
[20:41:20] <seb_kuzminsky> i agree with cradek
[20:41:35] <zhivko> my code is: like
[20:41:36] <zhivko> G01 X-32.5 Y250.0 Z63.7 A3.8 B3.8 F27564.0 (move length: 0.5 speed:14422.2 p:292, e:ONRADIUS no:273)
[20:41:44] <seb_kuzminsky> but i think you generally shouldn't care about how much lookahead there is - the path will be right in any case
[20:41:50] <zhivko> A and B actually always same.
[20:42:29] -!- remstw has quit [Quit: quit]
[20:42:49] <seb_kuzminsky> then you could set A and B before all your XYZ moves and get the new planner
[20:43:26] <jepler> I think that it is whether the other axes are commanded to move, not whether the axis letters appear, that determines the behavior
[20:43:29] <zhivko> but then setting a in b in previous move would be done separately ... but I want simultaneous with x y z
[20:44:22] <jepler> I encourage you to test and draw conclusions, because they are more likely to be accurate conclusions than what we say without resarching the matter ourselves.
[20:44:28] <seb_kuzminsky> zhivko: you said "A and B actually always same.", which makes me think they don't move
[20:44:33] <zhivko> to ilustrate my case (plasma cutting rectangular pipe) here is video:
https://www.youtube.com/watch?v=JdvwQDqcVmw
[20:44:43] <cradek> zhivko: what's your actual question?
[20:45:37] <zhivko> ok my question is can I somehow add debug info in tp.c, to know which vel_max is limiting move velocity in each step
[20:46:24] <cradek> change your moves to G0 like I suggested earlier, and use halscope
[20:46:55] <zhivko> cradek: how can I activate 2.6 planner ?
[20:46:56] <cradek> if you have planner-related low speeds, you should set your max velocities (and more importantly, accelerations) as high as possible and use moves that are as long as possible
[20:47:22] <cradek> for instance if you are splitting your corner radii into 10 small G1 moves now, try 6 or 4 moves instead
[20:47:41] <zhivko> I'm afraid Iloose precission this way
[20:47:55] <cradek> test
[20:48:05] <cradek> don't use your feelings to solve your problem, use data

[20:48:38] -!- pozzoni has quit [Ping timeout: 250 seconds]
[20:48:50] <cradek> it's plasma right? the moves you're splitting up are orthogonal to the cutting vector - I don't see how it can possibly affect precision
[20:50:11] <zhivko> but if I push your advic elittle bit further - I can imagine having only 2 lines aproximating radii - that could result in havingwrong distanc eof tooltip to surface
[20:50:22] <cradek> ok then try 4
[20:50:24] <zhivko> actually torch tooltip could slam into workpiece
[20:51:04] <cradek> your move length you pasted above is 0.5mm? what is the torch height?
[20:51:47] <zhivko> you mean distanc efrom torch to workpiec e?
[20:51:52] <cradek> yeah
[20:52:06] <zhivko> according to hypertherm it should be 1.5mm
[20:52:43] -!- kingarmadillo has quit [Ping timeout: 244 seconds]
[20:52:45] <zhivko> I get points from cad program - I can easily change 0.5mm to 2mm lets say to reduc enumber of segments...
[20:53:07] <cradek> first set your axis accels as high as possible
[20:53:29] <cradek> then if that doesn't get the speed you need, increase segment length
[20:54:00] <zhivko> OK thank you - ou think 2.6 planner can be better for combined moves?
[20:54:37] <zhivko> also I have question regarding max speeds
[20:54:50] <zhivko> but I guess I am not in right channel...
[20:55:00] <zhivko> maybe #linuxcnc is better.
[20:55:17] <jepler> fwiw if this is commercially important to you, maybe you should get in touch with Rob Ellenberg and offer him paid development.
[20:55:24] <jepler> I have heard indirectly that he is working on a 6-axis version of his planner.
[20:55:46] <zhivko> Oh really - I would be interested in this very much...
[20:56:51] <jepler> it was mentioned yesterday, that's all I know about it.
http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc-devel/2016-11-03.html
[20:57:08] <jepler> .. afk ..
[20:58:01] <zhivko> Why were a,b,c left out from planner - I mean couldn't be the same logic that applies to x,y,z couldnt be used on a,b,c ?
[20:58:22] -!- b_b has quit [Remote host closed the connection]
[20:58:51] <cradek> marginal utility compared to the effort required
[21:00:37] <zhivko> HOw od you get in contact with Rob ?
[21:00:47] <zhivko> sorry I mean how do I get ...
[21:01:16] <seb_kuzminsky> email to the emc-developers list is probably the best way
[21:01:37] <seb_kuzminsky> maybe Cc: Rob directly to make it more likely he'll notice it, you can get his email from our git log
[21:05:21] <zhivko> OK will try to do that!
[21:09:39] <zhivko> I hope it will be not so hard to port this to machinekit
[21:09:57] <zhivko> I mean trajectory planner

[21:56:09] <jepler> src/configure is a generated file, created by running ./autogen.sh in the src directory. Since files don't normally travel in time, perhaps it's just that the generated configure script doesn't match the rest of the source tree.
