[14:56:22] <andypugh> I guess that one of the sub-tasks of introducing G71 will be educating Touchy about it…
[14:57:09] <andypugh> Whether you can usefully MDI a G71 I am not 100% sure, I guess it depends on how it can find the subs.
[15:06:52] <cradek> I can imagine it being useful as macros
[15:07:11] <cradek> but you sure can't mdi a profile (in any gui)
[15:19:20] <andypugh> But, if it can find named subs in other files (and I think bpuk has that working) then it could be useful.
[15:20:31] <andypugh> Looks like I need to poke around in the guts of Touchy anyway (or make my own lathe GUI). I have 4 jogwheels, so ought to make the touchy-buttons be displays rather than controls.
[15:59:48] <Skofyx> So, question. In (stock linuxcnc 2.7) /boot/config-3.4-9-rtai-486 for some reason, CONFIG_M686=y is set.
[16:00:38] <Skofyx> Seemed just a wee bit odd for a kernel variant called '486'
[16:20:43] <andypugh> 486 seems odd altogether
[16:21:22] <Skofyx> How so?
[16:21:51] <andypugh> Sorry, I mis-read that as a kernel uname
[16:22:01] <seb_kuzminsky> i'm pretty sure that setting was inherited from the Debian i686 flavor
[16:23:12] <Skofyx> A diff of config-3.4-9-rtai-486 and config-3.4-9-rtai-686-pae shows them to be basically identical.
[16:23:57] <seb_kuzminsky> the 486 kernel was an experiment, it was never promoted as a useful option for users
[16:24:45] <seb_kuzminsky> are you trying to run linuxcnc on a machine with a pre-i686 processor?
[16:25:06] <Skofyx> Via c3. (686 class sans cmov/cx8 etc)
[16:26:02] <Skofyx> So I need either 586 (or less), or c3. Was hoping that the 486 kernel would work.
[16:28:42] <seb_kuzminsky> you're probably best off building an appropriate kernel yourself, and building linuxcnc for it yourself
[16:29:17] <seb_kuzminsky> the build system that we used to produce the 3.4 rtai kernels is here: https://github.com/SebKuzminsky/linux-rtai-build/tree/3.4-wheezy
[16:29:50] <seb_kuzminsky> i don't know if rtai will work well on i586, in my experience it's a little brittle
[16:31:06] <Skofyx> Well, technically, the Via c3 is just a LTSP client. :D
[16:32:00] <seb_kuzminsky> if it's just a terminal, why do you want rtai on it?
[16:32:10] <Skofyx> (which I'm tied to because it is wired to my touch screen)
[16:33:20] <Skofyx> Good point. Are there any true i386 kernels in the repos?
[16:34:36] <seb_kuzminsky> https://packages.debian.org/wheezy/linux-image-3.2.0-4-486
[16:37:19] <Skofyx> Okay, 3.2.0-4-486 is configured CONFIG_M486=y
[16:40:48] <seb_kuzminsky> good luck! bbl
[16:40:53] <Skofyx> Thanks!
[17:39:18] <andypugh> cradek: I tried the remapped G71 on actual (expensive) metal: https://www.youtube.com/watch?v=2TLzbF5POMk&t=3s
[18:16:53] <skunkworks> zlog
[19:30:03] <Skofyx> Well, looks like I'm stuck with Ubuntu 8.04. (debian wheezy + ltsp is either broken or _very_ difficult to get working)
[19:52:12] <andypugh> That seems surprisingkly ancient. But 8.04 did work well with LinuxCNC.
[20:03:10] <Tom_itx> just can't run some of the new features can you?
[20:03:42] <andypugh> No, you lose the new TP, so for fast profiling it’s not ideal
[22:22:28] <cradek> awesome
