[20:22:45] <SWPadnos> got a spindle-synched motion question: is it possible to specify a synchronized move that uses all axes?
[20:23:25] <cradek> yes
[20:24:08] <SWPadnos> ok, so for example a rigid tap could include all axis words, and it would move all the axes like a "standard" move (ie, in pseudo-inverse-time mode), but synched to the spindle
[20:24:28] <cradek> I think g33.1 doesn't let you move rotaries
[20:24:30] <cradek> g33 does
[20:24:40] <SWPadnos> (not that it's useful to do, just want to understand the limitations before I respond to an email on the cnc-toolkit list
[20:24:42] <SWPadnos> )
[20:24:44] <SWPadnos> ok
[20:26:20] <SWPadnos> in case you're interested, here's the original set of statements with my responses interleaved: http://pastebin.ca/1846948
[20:26:33] <SWPadnos> and his response to me: http://pastebin.ca/1846949
[20:33:18] <cradek> what's the expression I'm looking for? something about pissing up a tree?
[20:33:25] <SWPadnos> heh
[20:33:35] <SWPadnos> or spicy fly shit or something
[20:34:09] <SWPadnos> I'm not trying to convince him to use EMC2, I don't really care about that. I just don't want his seemingly authoritative opinion to be taken as fact by others
[20:35:09] <cradek> yeah, that's important, but you'll get it on you
[20:35:14] <SWPadnos> heh
[20:38:20] <SWPadnos> I just want to be factual in anything I represent as fact, so I figure it's a good idea to ask people who actually know the answers (or test on my own) when I'm not sure about something
[21:06:29] <ries_> ries_ is now known as ries
[21:24:22] <alex_joni> SWPadnos: mocca will be shortly rewritten for xml support
[21:24:37] <alex_joni> I think a couple more weeks and there will be a screen designer for it
[21:24:46] <SWPadnos> and that means?
[21:25:12] <alex_joni> I'm not sure I'll use it, but it'll be at least the way to shut up people that want the Mach screen designing functionality
[21:25:27] <SWPadnos> heh
[21:25:33] <SWPadnos> what is mocca?
[21:25:37] <alex_joni> the whole GUI gets constructed based on the config xml, including strings, placement and shape and color and whatnot
[21:25:43] <alex_joni> emc2 GUI in freepascal
[21:25:45] <SWPadnos> I don't see it in the first several google hits
[21:25:47] <SWPadnos> ah
[21:25:49] <alex_joni> written by gtom
[21:25:54] <SWPadnos> ah, ok
[21:25:55] <alex_joni> moccagui iirc
[21:26:10] <alex_joni> http://code.google.com/p/moccagui/
[21:26:14] <cradek> did they get their gpl problems sorted out? I know jeff was trying to help them.
[21:26:20] <SWPadnos> right, found it
[21:27:29] <SWPadnos> so if someone would write a GUI that would output XML files, that would pretty much answer the complaints
[21:27:56] <SWPadnos> oh, so that might be the screen designer you mentioned (duh)
[21:28:01] <alex_joni> cradek: it's a bit problematic
[21:28:10] <cradek> I don't like the sound of that
[21:28:24] <alex_joni> the issue is that (according to him) in germany you cannot reliese a piece of software without liability
[21:28:49] <alex_joni> (he did put a GPL notice on the files jeff wanted)
[21:29:01] <alex_joni> SWPadnos: http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/id,1813/catid,38/
[21:29:33] <cradek> iirc, the eu-fsf guys who responded to jeff's messages said he's just mistaken that being in germany makes this difficult
[21:29:54] <alex_joni> I don't know anything about that
[21:30:11] <cradek> until licensing issues are clearly solved I would hesitate as a board member to talk about mocca as a solution to any perceived problem
[21:30:11] <alex_joni> only what gtom posted on the german forum (cncecke)
[21:30:54] <alex_joni> well.. the license mentioned at: http://code.google.com/p/moccagui/ is GPL v2
[21:31:07] <alex_joni> so my assumtions could be all wrong
[21:31:19] <alex_joni> maybe jepler knows this better
[21:32:14] <SWPadnos> the last comment in that thread talks about the perceived issues with the GPL in europe
[21:32:45] <alex_joni> yeah, but those are old
[21:36:18] <SWPadnos> it's all I know :)
[21:36:47] <alex_joni> ok, just reread the thread he started about licensing in the german forum
[21:37:08] <alex_joni> he started the project with GPL v2 license, and he stands by that license (absolutely no problem with it)
[21:37:52] <alex_joni> the only thing that he's a bit reluctant to do is to write his name as the copyright holder, as that involves liability in case of anything in germany
[21:38:17] <SWPadnos> ah
[21:38:20] <alex_joni> even if the software is Free/Open Sourced
[21:39:15] <alex_joni> he did register the project at google code, and put the license as GPL v2 since the beginning, but was a bit upset that jeff asked him to explicitely put that license again on 2 files
[21:40:17] <alex_joni> 1 taken from emc2 emcpas.cc and 1 taken from emc2 but contains no difference than the original emc1 code: simcanon.cc
[21:46:39] <cradek> jeff didn't ask him to add a license statement - he asked him to NOT remove it from the files he took from emc2 and modified
[21:48:21] <alex_joni> cradek: no point in fighting someone elses battle :)
[21:48:57] <cradek> alex_joni: well I was an author of those files too and was CC'd in all the emails.
[21:49:23] <alex_joni> I wasn't cc'd so I'm mostly guessing
[21:49:37] <cradek> bbl
[21:49:39] <alex_joni> and interpreting what gtom posted (that he took code, not files0
[23:54:41] <cradek> seb_kuzminsky: I anxiously await the awesome future!
