[00:32:16] <KimK> andypugh: Welcome back, is sailing done already? Or are you just in-harbor or something?

[00:32:53] <andypugh> Sailing is done, at least until next week when I might be delivering the boat to Londonderry for a naming ceremony.
[00:33:51] <KimK> Well, congrats then, hope you had fun. And will have, if you do the delivery.

[14:27:22] <dgarr> Is there interest in including ngcgui in 2.5? If so, for consideration is a patch that simplifies its use and includes examples:
[14:27:24] <dgarr> http://www.panix.com/~dgarrett/stuff/0001-ngcgui-for-v2.5.patch
[14:28:53] <JT-Shop> that would be neat
[14:29:08] <JT-Shop> thanks for ngcgui dgarr
[14:30:10] <dgarr> if anyone tries it, please post comments or suggestions
[14:31:18] <JT-Shop> oh, for a while people were getting site has had too much traffic when trying to get ngcgui so I mirrored it on my site
[14:32:09] <dgarr> thanks, my panix site was clobbered by bots for a few days
[14:32:44] <dgarr> note: the patch uses tcl packages so users don't have to manage or locate the tcl scripts (as they must with the tar file)
[14:35:53] <JT-Shop> nice
[14:36:43] <JT-Shop> I'll give it a try in the am or this afternoon if I get this automation conversion done today :/

[19:52:49] <JT-Shop> is it possible to have all homing and limits on one pin?
[19:53:17] <andypugh> Yes.
[19:53:33] <JT-Shop> or can you only have home and combined for one axis?
[19:53:45] <JT-Shop> 50/50 huh
[19:54:01] <andypugh> I had them all combined when I first built my mill.
[19:54:21] <JT-Shop> wonder why the chap on the forum can not get it to work...
[19:54:33] <andypugh> You need IGNORE_LIMITS set in the homing config, and there needs to be a one-axis-at-a-time sequence set.
[19:54:46] <JT-Shop> he is doing that AFAIK
[19:55:19] <JT-Shop> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/id,9633/catid,38/limit,6/limitstart,0/lang,english/
[19:55:56] <andypugh> I am way behind on the forums
[19:58:05] <cradek> when axis 0 is homing, axes 1 and 2 will see a limit switch being hit
[19:59:01] <cradek> you could use homing-state on 0 to mask these incorrect limit hits on 1 and 2 (etc)

[20:25:31] <mhaberler> cradek: I just noticed that iocontrol-v2 is not in v2.5_branch but just in master. How do you feel about it?
[20:30:44] <cradek> I forget how big the changes are. do you have a branch I can look at?
[20:31:27] <mhaberler> I guess I need to excise one first, I sortof lost track of it and lacked git style than ;-)
[20:31:41] <cradek> yeah it's easy to lose stuff.
[20:31:44] <mhaberler> will do.
[20:33:00] <cradek> I know iov2 is a separate binary, which is fine. what I don't remember is what changes are made to everything else. these might possibly introduce instability and I want to think about them again.
[20:33:38] <mhaberler> in Interp its only the start-change NML message, what skunkworks requested
[20:34:06] <cradek> and you make iov1 just ignore that?
[20:34:19] <mhaberler> yes. that one was trivial, but nevertheless I'll do a proper branch,
[20:34:30] -!- WesBaker has quit [Ping timeout: 264 seconds]
[20:35:44] <cradek> it seems like it should be fine if those are the changes
[20:37:28] <mhaberler> I still need to pull bits and pieces into one place, I'll never do it later
[20:51:04] <andypugh> cradek: I thought you could tell EMC2 to ignore limit switches during a homing sequence?
[20:51:31] <cradek> you can tell one joint to ignore ITS limit switches during ITS homing
[20:51:51] <cradek> notice with this one-pin setup you are triggering limits on joints that are NOT currently homing
[20:52:28] <andypugh> Ah, OK. I must be misrembering how my p-port setup worked before I went 7i43
[20:52:42] <cradek> or I am mistaken, but I don't think I am
[20:53:18] <cradek> you could argue for (and certainly against!) ignoring all limit switches during any homing motion
[20:53:28] <andypugh> It seems reasonable that you _could_ ignore limit switches being set on non-moving axes
[20:53:31] <cradek> but that is not implemented (except you have the power to do it in HAL)
[20:54:20] <andypugh> I feel an experiment coming on.
[20:54:23] <cradek> limit switches are important when a joint is doing something you don't expect. it's hard to say what joints are non-moving.
[20:55:43] <cradek> you could do this setup very very easily in ladder or slightly tediously with a bunch of and2 components or somesuch
[20:56:17] <cradek> two pins -- one for all homes, one for all limits, is a better solution if you can swing it
