I've seen enough Sherlines to last me a lifetime. 15:11:16 Nothing wrong with Sherlines, just that they seem to be the ones that make it to all the shows due to small size. 15:11:43 Sunday morning, the sun was out and we took a long walk and talked for a couple hours 15:11:58 It was a good weekend 15:12:17 Sunshine? I though Paul liked caves? 8-) 15:12:24 he does 15:12:54 Saturday it was foggy and rainy and he said it reminded him of home 15:13:32 I think he taught me more this last weekend than I would learn on my own in a year 15:14:04 hm.. 15:14:40 we had some discussions on lathe coding 15:14:49 did you end up with a system running the 2.6 kernel? 15:15:14 we set up BDI 4.15, which I think is running 2.6 15:15:28 great, a "live" user! 15:15:45 I actually wasn't as concerned about the kernel as I was the machine code 15:16:21 we discussed the GUIs, switches, DA cards 15:16:23 understandable, but many folks are chomping at the bit to move to the newer kernel 15:16:49 lathe mode is going to be a long slow process, there are so many special issues on a CNC lathe 15:18:15 what are the advantages of the 2.6 kernel? 15:19:50 It's funny, we didn't dicuss the kernel while Paul was here 15:19:53 I am not sure that it matters much for EMC, just that people are used to 2.6 on their desktops and want same on EMC, especially people who are new to EMC and have not used older kernals. 15:20:10 oh ok 15:21:04 it's funny, most of our discussions related to making the computer look more like a machine tool control and less like a desktop computer 15:21:15 hence the machine booting up emc automatically 15:21:33 we even went to a surplus store in search of touch screen panels 15:21:43 2.6 does offer "soft" realtime, but that is not fast enough to support EMC so RTAI or RTLinux is still used. 15:22:23 well, I need to go to work. I will talk more this weekend. 15:23:21 I like the idea of conforming to look more like real machine tools, but I am not a fan of touch screens. I like real button alongside that get labeled by the text on the screen. 15:23:52 later Dan... 15:24:32 hmm.. 15:25:01 * anonimasu cant seem to find out why he's loosing steps 15:28:32 I usually try running slower as a sanity check first, then if that is OK, start chasing the other issues. 15:29:41 hm that dosent seem to be it.. 15:29:54 I am running ~ 20mm/min 15:30:01 with 0.5 as accel.. 15:30:44 picnet has joined #emc 15:32:10 if you tell me more about your setup, I'll be happy to start guessing 8-) 15:34:16 I need to go got to rest a bit :/ 15:34:41 ok 15:38:13 SteveStallings has quit 17:53:22 Jymmm has joined #emc 18:09:33 picnet has quit 18:57:01 robin_sz has joined #emc 18:57:07 meep! 19:05:41 Imperator_ has joined #emc 19:31:18 picnet has joined #emc 19:44:45 alex_joni has joined #emc 19:48:04 greetings 19:49:01 hi 19:50:41 hey robin 19:50:49 * alex_joni has seen some nice milling machines today 19:52:14 bigg and fast? 19:52:28 wanna see some pics? 19:52:33 go on 19:52:34 * alex_joni uploads some 19:52:46 will take a while 19:52:52 don't know about fast.. but big 19:53:17 picnet has quit 19:53:53 sorry about the poor picture quality.. but it was very dark (and no flash powerfull enough to lighten them) 19:59:07 anyways... how have you been? 20:02:20 well, busy 20:02:29 was supposed to fly out to Geneva toady 20:02:35 "nice milling machines today" $$$$$$$$ or |<---------------------------->| 20:02:42 didnt though .. go next week 20:03:31 I desperately need to get this server out of the house and isntalled in a rack 20:03:44 too bloody noisy for home use! :( 20:04:48 lol ;) 20:05:01 pack it in the basement 20:05:42 basement? heh you dont get basements in 200 yr old barns ;) 20:05:51 dig 20:05:52 one 20:05:54 ;) 20:06:11 no chance .. the foundations are already shaky enough 20:06:19 bummer ;) 20:06:28 how about the attic then? 20:06:35 full. 20:06:47 and Id still hear it 20:06:55 http://www.robcon.ro/emc/bigmachines/ 20:07:05 not all pics there yet.. check again in 5 mins 20:07:35 without being a smartass here, whay does the BDI need so much cpu power? 20:07:50 for the RT stuff 20:08:02 the more CPU power you have, the faster pulses you can output 20:08:09 thus .. faster milling 20:08:51 Ok, I suspect I'm clueless here, especially when I've seen things run on MS-DOS 20:09:01 md-dos is actually easy 20:09:05 no multi-tasking 20:09:32 wait... DOS has a benefit of nix?! =) 20:09:37 s/of/over/ 20:09:46 Jymmm: just remember EMC does a lot more than step-pulse generate. It will take servos and do full servo loop calculations in realtime .. 20:09:58 well... depends on the point you look at 20:10:14 * Jymmm <---- clueless (mostly), just getting started. 20:10:18 robin: of course, and a LOT more (including 6-axis interpolation) 20:10:31 and look-ahead motion planner 20:10:32 etc 20:10:35 Does emc do loop ahead? 20:10:39 look 20:10:40 yep 20:10:48 Ah, ok, that explains it 20:11:10 * Jymmm thought he was goin nuts...
