00:39:36 rayh_ has joined #emc 00:48:08 picnet has quit 00:59:38 rayh has quit 02:22:30 hi guys 02:23:16 hi dan 02:24:17 How are things going w/ Axis? 02:24:47 well, I use it all the time 02:25:19 I think it works just great 02:25:39 I'm going to start using if to check out G-code 02:25:54 it's definitely good for that 02:25:54 I found that Sagcad can output the code for me 02:27:00 I'll probably set up some combination of SagCad and Axis 02:27:05 darnit, I can't remember how to make autocad go into setup mode at the commandline 02:27:46 picnet has joined #emc 02:27:58 is sagcad that japanese one? 02:28:23 yes 02:28:37 but the subtitles are in english :) 02:28:42 did you get it to do anything neat? 02:29:11 yes. I can actually draw profiles with it then generate gcode, one profile at a time 02:29:32 gezr helped me set up vim w/ his syntax highlighting for gcode 02:29:55 so you draw lines and arcs, and it generates that path? 02:30:04 is that what you mean? 02:30:16 so, you draw the profile, click the g-code button, select the path and direction of cut 02:30:27 click through a dialogue box 02:30:39 then the editor pops up with your g-code 02:30:50 nice 02:30:51 it surprised the hell out of me 02:31:04 please tell me exactly what you mean when you say "profile" 02:31:09 I looked at a binary last year and couldn't make heads or tales out of it 02:31:26 compiling it on my system gives me english buttons though 02:31:44 profile as in lines and arcs chained together 02:31:56 aha, polylines 02:31:57 they don't have to be closed though 02:32:00 (I'm an autocad user) 02:32:17 I used to be too 02:32:28 I use autocad for that with homemade lisp to output gcode 02:32:35 I use ashlar vellum at work 02:32:47 we just bought ProE linux version though 02:32:56 it's great because you can use "offset" to generate a toolpath from a polyline that represents the part 02:33:38 yes, I use offset a lot (not in sagcad though-haven't figured that one out yet) 02:34:10 are you running acad under native windows environment and moving files to a linux box? 02:34:46 I use acad r12 running on FreeDOS running on QEMU running on Linux 02:34:52 cool 02:35:18 two days before I graduated from college I bought the full version of acad r12 at the student price of $99 02:35:25 best $99 I ever spent 02:35:36 yes acad12 is great 02:35:44 used it a lot some years ago 02:36:06 I have acad2000 but haven't used it much in a couple years 02:36:10 it has a windows version but I never got used to it - always liked the dos version better 02:36:22 the dos version was fast 02:36:27 I have a tablet somewhere that works with it but it takes too much desk space 02:36:45 I (briefly) ran acad for a day job 02:37:13 I have been using Qcad a bit lately to make dxf files for sagcad 02:37:23 It's really hard for me to get used to 02:37:40 so you draw plines in qcad and load the dxf in sagcad to generate gcode? 02:37:45 I used to think it was just a toy, but now it doesn't look too bad 02:37:53 yes you can do that 02:38:04 It works out easier that way 02:38:19 sagcad's drafting is pretty obtuse 02:38:50 are you doing 3d or 2.5d? 02:38:57 but, sagcad has a pretty small footprint and is more interesting than just using command line stuff 02:39:05 rayh_ has quit 02:39:09 it's only 2D 02:39:14 ah 02:39:19 not even 2.5D :) 02:39:22 so how do you specify depths, feeds etc? 02:39:35 do you still have autocad? I could give you my lisp. It's 2.5d 02:39:36 you have to manually insert them in the editor now 02:39:45 bleah 02:39:46 sure, I would like that 02:40:06 I still have it on another machine (in the garage at the moment) 02:40:27 I will be using it as soon as the weather gets warmer and I get the shop set up 02:40:51 thanks 02:41:01 ±documentation at the top of the file 02:41:07 I'll look in my dir to make sure it got there ok 02:43:00 ok got it 02:43:07 let me send a file to use with it to experiment 02:43:10 ok 02:43:15 it cuts out a hole for a DB25 connector 02:44:28 ok thanks 02:45:12 sure 02:45:18 it works great for simple stuff 02:45:47 so, are you a python programmer? 02:45:55 more or less 02:46:00 I like python 02:46:18 I have been studying it for a while, but not really programming 02:46:21 I've done a couple big projects in it, but I'm not sure yet whether I like it 02:46:37 are you a C programmer? 02:46:54 yes 02:47:09 I'm a programmer in lots of things I guess 02:47:30 is working on emc going to burn you out? 02:47:38 programming all the time... 02:47:47 I haven't done much programming in emc - I just fix the bugs that bite me. 02:47:52 ok 02:47:57 I don't really have much interest in developing emc2, sorry to say. 02:48:03 you want to get some machines going then 02:48:16 I have my machine working perfectly with emc now 02:48:20 good 02:48:32 I made a new 3-axis chopper stepper drive box with spindle control 02:48:37 just finished 02:48:43 I'm really happy with it 02:48:47 what chips did you use? 02:48:53 instead of 10ipm on my mini mill, I get 25 now 02:48:59 wow 02:49:01 L297/8 02:49:10 cool. I've used them in the past 02:49:11 the drivers that came with it ... sucked 02:49:24 what did you have before? 02:49:40 a transistor and resistor per winding 02:49:53 was it commercial? 02:49:55 and a low-voltage power supply 02:49:57 yeah, maxnc 02:50:07 the mill itself and steppers are good 02:50:16 oh yeah. I've delt with them before 02:50:18 but the spindle motor sucks, the controller sucks, the software sucks 02:50:20 a long time ago 02:50:27 so I replaced all that with stuff that doesn't suck 02:50:29 the software is what I used 02:50:33 now it's a great mill 02:50:35 it sucked 02:50:38 hahaha 02:50:40 I need to go 02:50:42 dinner time 02:50:44 ok, goodnight 02:50:46 thanks 03:29:41 hi chris 03:32:11 your mill isn't *done* at least until you do the spindle speed control and make the spindle go faster 03:45:52 picnet has quit 04:28:20 picnet has joined #emc 05:42:21 * asdfqwega has rewired his stepper control / parport breakout / PWM laser control 05:42:45 Yes, you too can use Rats-Nest(tm) Technology! 05:47:34 Crivens, this is fugly. 05:47:57 I've got two parports going into the control box 05:48:47 I've got two IDC connectors on the shell, but I split up the ribbon cable and wire everything in the air 05:50:22 So I have this spaghetti tangle ball, and I hold it up with a few wire-ties so the fan can blow on to the driver heatsinks. 05:51:12 The only good thing is, it works...and better than the PCB and proto board I was using. 05:55:34 So I've got it working again...what do I do now? 05:59:59 picnet has quit 06:29:02 picnet has joined #emc 12:32:01 logger_aj has joined #emc 12:32:01 topic is: Welcome to the Enhanced Machine Control forum | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT 12:32:01 Users on #emc: logger_aj anonimasu alex_joni thalx danfalck @ChanServ CIA-5 ccjoe les A-L-P-H-A cradek asdfqwega learath @pc_op jepler zwisk gezr websys 12:41:21 picnet has joined #emc 13:08:07 alex_joni: /me yawns 13:08:10 err 13:08:12 * anonimasu yawns 13:09:01 * alex_joni agrees 13:09:09 I'm waiting to get off work 13:09:11 :D 13:09:28 :) 13:09:29 me too 13:09:35 so I can try get the mill functioning.. 13:09:46 yeah... 13:10:18 about 2 hours 13:10:20 I have one hour advantage... it's 15:10 here ;) 13:10:20 maybe 1:30 13:10:40 but I dont know if I should take some time to practice tig welding :) 13:10:59 tig welding is cool 13:11:02 yeah 13:11:18 I wish I had a welder like the one at work at home :) 13:11:45 although there's no one that really knows how to weld with it yet.. 13:12:04 welding alu is hard :) 13:12:29 * alex_joni really likes microplasma 13:12:42 welding alu is not that hard 13:12:49 isnt it? 13:12:50 but you need an AC one 13:12:53 not really hard 13:13:30 the tig I weld with is a ac one.. 13:13:43 what alu-thickness? 13:13:54 3mm 13:14:09 the tig's a 350A watercooled new oerlikon unit.. 13:14:25 350A is way over for 3mm 13:14:37 about 1cm.. without preheating.. 13:15:04 what type of welding? 13:15:07 buttwelding? 13:15:14 with or without filler wire? 13:15:26 with filler 13:15:39 I'd go around 100-150 A 13:15:49 depends on the weld you need 13:15:50 120 is what I weld with.. 13:15:55 sounds ok 13:16:28 still welding alu is hard :) or requires lots of training 13:18:34 stainless is really neat :) 13:18:45 did you see the image of the machine? 13:18:49 yeah.. I just welded some stainless 13:18:54 nice machine 13:19:03 :) 13:19:06 1.5 mm stainless steel containers 13:19:10 nice :) 13:19:19 but not manually ;) 13:19:25 hehe 13:19:32 welding robot? 13:19:49 I always choose to weld with a robot or automat 13:19:53 :) 13:19:56 this time it wasn't robot 13:19:59 ok 13:20:01 tig is hard with a robot 13:20:05 yeah probably 13:20:10 you mean wire feeder? 13:20:17 because you need to keep the distance to the piece 13:20:25 height is very crucial for TIG 13:20:29 yeah yep 13:20:38 MIG/MAG doesn't really care (5-15mm is pretty ok) 13:20:45 yeah 13:21:02 but well, mig dosent compare to tig, either 13:21:09 mig is nicer ;) 13:21:16 you can even weld alu :D 13:21:32 yeah but the welds will look like crap ;) 13:21:37 tig is slow ;) but more accurate 13:21:42 used to have a mig for welding alu here.. 13:21:49 not really crap... depends on the welding power source 13:22:03 well, tig is nicer although not in mass production 13:22:10 the company I work for (CLOOS) sold some MIG-Tandem for ALU 13:22:31 it was for the new ICE-trains (Deutsche Bahn) 13:22:37 ah ok 13:22:40 they weld the side panels of the cars 13:22:46 yeah if you are going to weld lots there are better things then tig.. 13:22:49 so they need fast/good alu welds 13:22:56 MIG/YAG 13:22:57 :D 13:23:00 tig isnt really speedy ;) 13:23:17 yeah... but it's very clean (no noise, no spatter) 13:23:23 yeah 13:23:35 good welds also.. 13:23:43 but that depends on the welder 13:23:44 :) 13:23:53 but a bad tig weld looks bad :) 13:24:18 so does a bad MIG weld ;) 13:24:28 not nesscesarily.. 13:24:35 http://www.sudura.ro/pub/a14.jpg 13:24:42 some MIG weld I did a while ago 13:24:48 I've seen wonderful mig welds.. on the outside 13:24:53 that looked like OooOoo inside.. 13:25:00 lol 13:25:04 looks nice... 13:25:10 yup.. but not manual ;) 13:25:19 kind of expected that :) 13:25:31 all I do is robot welding... 13:25:39 hehe 13:25:46 picnet has quit 13:25:59 we mostly do one off stuff where I work so robots isnt a good option :9 13:26:41 probably not ;) 13:27:30 dosent welding alu with mig splatter lots? 13:27:49 not really, if you got a ALU MIG power source 13:28:16 ah in that case I dont know 13:28:55 but when welding alu with a regular normal mig :) it splatters like hell 13:29:17 the ones from CLOOS have a function called ALU-PLUS 13:29:20 MIG with pulse + Alu-Plus 13:29:49 ah ok 13:30:12 I'd buy a multi-process if I had to buy a welding machine 13:30:17 MIG/MAG/TIG/Stick 13:30:48 hm, I'd go for a small tig from like miller.. 13:30:51 for home use.. 13:31:00 I saw some good offers somone on cnczone bought.. 13:31:30 although I dont know if that machine had upslope an 13:31:35 and downslope and things 13:31:46 but there were a model a notch over it that did 13:31:50 they seemed pretty affordable.. 13:32:51 this is a great TIG machine: http://www.robcon.ro/sudura/images/glw300ih.jpg 13:33:11 but a lot bigger than home use ;) 13:33:11 :) 13:33:18 looks simmiliar to the one we have at work.. 13:33:23 similiar.. 13:33:46 although what do you weld with 300A at home ;) 13:34:05 yeah... 13:34:13 I'd buy a microplasma for home ;) 13:34:17 0.5A - 80A 13:34:22 I've never seen anything like that 13:34:26 just on some ads.. 13:34:28 it's the best 13:34:39 I played once with one, before we shipped it 13:34:50 I didn't even use a welding mask D: 13:34:56 heh 13:35:09 http://www.robcon.ro/sudura/images/gl80.jpg 13:35:25 you can weld .1 mm sheets 13:35:37 neat :) 13:35:57 and it's not very expensive... 13:36:08 around 6k EURO 13:36:21 ouch :D 13:36:30 for home use that's very expensive 13:36:42 I agree... but for industrial use... 13:36:44 the tig I was thinking about costs about 1000eur at max.. 13:36:45 yeah 13:37:06 I just got a request from a friend 13:37:11 who welds some auto-parts 13:37:12 how thick stuff do you weld with a micrplasma? 13:37:21 you can go up to 2-3mm 13:37:24 ah ok 13:37:24 :) 13:37:28 depends on the weld you need 13:37:40 well, any kind of weld almost with full penetration.. 13:37:43 the advantage is that you have a pilot-arc 13:38:02 yep 13:38:20 you can use a tig like that if you want also.. 13:38:52 a microplasma is actually a tig with plasma gas around it 13:38:57 you have 2 gases 13:39:03 one inside (for the plasma) 13:39:13 and one for shielding (like for tig) 13:40:37 ok 13:41:11 http://www.twi.co.uk/j32k/protected/band_3/jk7.html 13:43:27 nice 13:46:53 * anonimasu has trouble about a sensor 13:47:26 hold on need to run for a bit 13:51:58 ok 14:05:45 iab 14:06:48 it solved itself 14:08:49 hihi... generally I'm scheptic to such solutions ;) 14:09:37 lol 14:09:58 it was about zeroing the sensor.. 14:10:09 I see... well then ;) 14:10:44 I had a talk to my father, about it.. the issue solves itself because the speed of the huydralics will be enough.. 14:11:03 to get to a position where the sensor isnt in use.. 14:11:54 otherwise you might lock the machine up by waiting for a signal you dont get.. unless I code in a timeout while in motion.. but I'd rather not do that since its not use friendly.. 14:12:10 or well I might do it anyway.. 14:12:19 although not user configurable.. 14:13:14 * alex_joni likes undocumented features :D 14:13:35 they will be documented.. 14:13:51 but not in the user manuall ;) 14:13:53 manual. 14:13:53 :P 14:13:57 the techie one.. 14:14:35 * anonimasu hates things users can set.. 14:14:38 sensors are better :9 14:15:04 having sensors instead of times for functions are much more efficient.. 14:15:20 but it also increases the cost 14:16:08 the cost isnt compareable to the increase in speed the customer sees.. 14:16:17 or well overall effiency.. 14:16:31 well then.. go for it ;) 14:16:50 this thing has to go up/down/do its stuff 2000 times per hectar.. 14:17:12 a lot of trees :D 14:17:15 yeah.. 14:17:28 at 2kmh you need to do about one every 1,8sec.. 14:18:00 which I can do easily, but even 0,5s adds spacing to them.. 14:18:33 yeah 14:19:09 it's somthing like 5000/600 14:19:12 m 14:19:17 per sec at 5kmh 14:19:18 ;) 14:19:34 err wrong.. 14:19:38 but maybe 0.8m.. 14:20:03 somwhere around that :9 14:20:10 so every delay is lots.. 14:20:17 the work is inspected aswell.. :) 14:21:34 they check while they run so they have a certain number of "good" spots.. 14:21:48 in a area of 10x10 14:21:51 m 14:21:58 every once in a while.. 14:25:09 ^_^ 14:41:57 picnet has joined #emc 14:49:52 time go head home 14:50:08 c u 14:50:37 yeah 14:50:40 laters :) 14:50:46 I'll see if I get the mill running later 15:30:26 * alex_joni is gone 15:30:28 alex_joni has left #emc 15:33:26 SWPadnos has joined #emc 15:33:38 SWPadnos has left #emc 15:47:37 picnet has quit 16:12:42 slomo has joined #emc 16:53:52 picnet has joined #emc 17:48:10 slomo has left #emc 17:49:10 slomo has joined #emc 18:04:18 picnet has quit 18:54:31 picnet has joined #emc 19:31:26 alex_joni has joined #emc 19:31:36 * alex_joni waves 19:47:36 picnet has quit 19:50:52 no one around?

19:53:56 well, if I ruled the world it would. 19:53:58 in my experience it came slower :D 19:54:07 that's true. 19:54:14 UPS is pretty ok... 19:54:19 I really hate FedEx 19:54:28 at least the romanian office... 19:54:36 around here I think UPS destroys more stuff. 19:54:41 I had an urgent shipment (express or how it's called) 19:54:46 I would never ship anything remotely fragile with them. 19:54:54 and fedex got it to romania in a day, 19:55:03 and I received the package after 5 more days :( 19:55:14 I'd rather have late than destroyed 19:55:23 now that's what I call a "good" service 19:55:33 destoyed = bad packaging ;) 19:55:37 stuck in customs or something? 19:55:53 yeah.. and no interest 19:55:57 I agree - bad packaging is usually, but not always the cause. 19:56:11 they sent us a telegrame we should send them some papers 19:56:25 and that telegramme was sent by post, and we got it 3 days later 19:56:26 :( 19:56:35 huh 19:56:39 * alex_joni thinks they never heard of phones, or emails 19:56:47
