00:01:07 * robin_sz orders a new servre 00:01:11 server even 00:02:27 our current box is 17U, dual P3 600 00:06:49 bobh has joined #emc 00:07:03 Afternoon... 00:07:15 Hi Paul, 00:07:27 Darn name trasher. 00:07:32 bobh is now known as rayh 00:07:47 Hi Ray 00:08:03 Nailed that bug, now hit another problem. 00:08:06 Was just reading the post from the fellow who wanted to do it himself. 00:08:33 Here I sit with a knoppix i did and it is gradually sinking. 00:08:47 What is the status of the new release? 00:09:15 Looks like I need to raid another box for memory. 00:10:02 Wot! 2.6 is a memory hog. 00:10:21 no, but the BDI CD build system is. 00:11:07 Oh. Right. 00:11:17 Big hog. 00:11:49 Not quite as bad as Morph or Knoppix but.... 00:12:44 Are you needing to expand your laptop? 00:13:05 picnet has quit 00:14:30 using a Dell donated (hijacked) by Matt over @ S. 00:15:22 Okay. We just need him to hijack another memory stick and a hard drive, eh. 00:16:02 I brought my own HD preloaded with all I (thought) I need. 00:16:24 What was causing the homing problem with 4.08 00:17:39 A page fault in the leadscrew comp routines 00:19:09 Really. That sounds like some great dectective(sp) work 00:20:05 A few strategic print statements, and a hunch. 00:20:26 It's the hunch that makes the difference. 00:21:08 It's a pity the AMD doesn't produce a kernel oops like my celeron test box did. 00:21:46 Wow. So the celeron is a better development box? 00:21:58 It would have been much easier to run the oops through one of the debugging tools 00:22:56 Given the choice between a Celeron & AMD for dev work, I'd use both. 00:23:23 the AMD fails a little more gracefully. 00:24:28 I'm going to have to split - Dee is cooking dinner and she'll shout at me if I'm late again. 00:25:46 Will be here again from 9AM 00:26:32 paul_c has quit 00:26:33 jmkasunich has joined #emc 00:26:47 Hi John. 00:26:53 hi Ray 00:26:58 I was just looking for you 00:27:13 I'm a bit over the horizon. 00:27:32 but I'm waving in your direction. 00:31:48 jmkasunich: Did that storm dump there? 00:32:04 jmkasunich has quit 00:32:52 jmkasunich has joined #emc 00:33:02 well that was annoyin 00:33:34 moving some crap around on my bench and hit the switch on the power strip that feeds the puter\ 00:34:03 rayh, you still here? 00:34:11 You bet. 00:34:29 you have any use for AllenBradley 1394 AC servo stuff? 00:34:49 Yes! You got some? 00:34:53 oodles 00:35:17 they're closing down a lab (or maybe just cleaning it up) and a mind-boggling amount of stuff is getting scrapped 00:35:20 A couple of integration guys were asking if there would be any ac servo stuff at Roland's. 00:35:35 I already pulled 8 1Kw motors and 15 2Kw axis modules out 00:35:58 The dumpster? 00:36:01 just today I snagged 6 real nice jog-wheels 00:36:19 yep - actually the loading dock, from which it would be loaded onto a truck 00:36:36 I don't actually have to dive into the dumpster 00:36:43 Darn. Makes working for corporate sound attractive. 00:36:50 this stuff is _probably_ perfectly workable 00:37:03 you're familiar with the modular layout of the 1394? 00:37:12 (you probably know more about it than I do) 00:37:19 All we need is a good way to get it to Ill for the fest. 00:37:51 anyway, the axis modules seem perfectly fine, but the power supply/controller sections are engineering prototypes, lots of cuts and jumpers, no docs, etc 00:44:09 you are tooooooo lucky :) 00:44:26 It pains me to see all that stuff going to the trash 00:44:29 8 motors, 15 drives!! 00:44:37 yeah 00:44:38 that was the first batch 00:44:42 !!! 00:44:42 there are more in the dock now 00:44:55 save some for me :) 00:45:00 some of them would be perfect test benches 00:45:27 4 motors, 4 axis drive unit, all mounted in a rolling cart or 19" relay rack (originally used to develop the products) 00:45:52 1kw motors are a nice size for practical machines 00:46:12 the stuff is designed for 380/480V tho 00:46:21 encoders as well I presume? 00:46:38 there is some kind of encoder built into the motor 00:46:43 lovely 00:47:02 some of them are labeled "absolute", probably so they can be used to comutate the motor 00:47:10 whatever, I presume the AC380 is rectified to 560DC ... 00:47:15 inside the drive? 00:47:21 yep 00:47:52 so, a 240 single phase, txfmr -> rec, 560 DC @3kw .. 00:47:57 job done 00:49:08 unless they have all that 'one phase is missing, one phase sameas another pahse' nonsense in them 00:49:30 nice dumpster dive though :) 00:49:47 they are modular, one section is the DC power supply and brains, then there are axis modules with the current loops, PWM gen, and power module 00:50:08 extra neat! ... 00:50:21 I presume you have a 4x4 to haul this stuff home? 00:50:31 and a huge basement :) 00:51:18 pickup truck, yes (not 4x4), huge basement no 00:52:00 garage? 00:52:18 yep, but cold damp, and rusty 00:52:19 or is that full already ;) 00:52:37 well, theres always space for servos!! 00:52:49 stack them around the TV 00:53:02 for that nice rainbow effect? 00:53:29 for that nice complaining wife effect :) 00:54:23 you just have to build something now 00:55:27 too many projects, too little time 00:55:33 sigh 00:55:35 too te 00:55:38 true 00:56:09 try not to spend too much of it in the basement staring at a screen then :) 00:56:20 life considered too short!! 00:57:37 picnet has joined #emc 01:01:26 well, im jealous of your servo find jmkasunich 01:01:56 if shipping wasn't so hi I'd send you some 01:03:08 thanks ... 01:03:15 I suspect shipping is huge 01:03:26 I found a servo amp on ebay ... 01:03:32 ouput: 01:03:38 330VDC 01:03:52 150A(continuous) 01:03:58 0-5khz 01:04:31 its a copley ... output 50KVA, in 53KVA, quite fficient 01:05:12 www.ab.com/motion/servo/ 01:05:30 follow links to 1394 (drives) or 1326 (motors) 01:06:23 1326 AB torque plus? 01:06:47 dunno which ones 01:06:52 just 1326 01:07:34 (they're still piled under a bench in the lab... waiting for me to load and bring home, or toss back in the dumpster, depending on whether I can find uses (or users) for them 01:08:10 look lovely, 01:09:26 http://www.ab.com/motion/servo/1326ab_460v.html 01:09:30 these ones? 01:09:48 probably 01:09:56 http://www.ab.com/motion/servo/1326as_460v.html 01:10:00 either 1326ab or 1326AS 01:10:04 yeah. 01:10:11 very nice 01:10:16 5000RPM, 2.7N*m (24in-lb) 01:10:38 * robin_sz ponders sending a suitcase 01:11:00 I even have cables that mate with the motor connectors 01:11:11 jealous :) 01:11:22 you'll have to carry the suitcase...

I am talking about a particular case here 13:10:49 I was teaching some dudes how to do it 13:10:54 each had his mask 13:10:57 right 13:11:08 and I chose lighter masks to be able to see the arc better 13:11:15 shape, seam, etc 13:11:21 right 13:11:29 normally I don't use anything below DIN 14 13:11:34 that's ok 13:11:37 mine is a variable thing 13:11:43 I scrap those ;) 13:11:53 actually I sell them.. but I don't like them 13:11:54 picnet has joined #emc 13:11:57 but only rated to 200 amps ..
