00:00:16 right, off to go fiddle with some hardware 00:00:33 I hope that after this weekend I'll have a full mirror for the ISO's 00:00:43 kewl 00:01:20 paul_c: there was a nice discussion in here today 00:02:46 :) 00:03:05 * paul_c scrolls through the logs 00:03:54 Oh buggerit... pc_op disconnected on the 3rd 00:04:28 logger_aj, bookmark 00:04:28 See http://193.226.12.129/irc/irc.freenode.net:6667/emc/2005-02-11#T00-04-28 00:08:55 * rayh is going for dinner. 00:08:58 rayh has quit 00:12:26 * anonimasu yawns 00:12:44 * alex_joni joins him 00:13:28 I hope the guys from germany keeps in touch about the PWM problem tomorrow.. 00:13:53 or modify their kernel to give me my damn pwm outs. 00:13:54 working :) 00:14:01 I hope I can get up in the morning ;) 00:14:10 what time is it there? 00:14:20 2 am 00:14:24 ouch 00:14:28 it's only 01:19 here 00:14:29 :) 00:14:34 but I have a fever now.. 00:14:35 hehe 00:15:18 I might get some production work for my mill soon 00:16:22 maybe :) 00:16:39 cool 00:17:13 or well, I'll get production work if I get the mill running good enough 00:18:29 but the parts will be pretty advanced.. 00:18:36 loads of toolchanges... 00:18:49 cool 00:19:13 I am just thinking about stainless steel vs alu.. 00:20:07 I am unsure which one that'd suit the app best.. 00:21:17 alu might do as good as stainless.. 00:21:48 athe moving parts will have plastic bushings anyway.. 00:22:06 so I think stainless if overkill 00:25:11 I have a jig in my head for making 3x of the parts in one setup, to minimize toolchanges.. 00:28:23 anyway.. I need to sleep now 00:28:25 night 00:28:33 n8 00:43:18 * alex_joni is going to sleep 00:45:24 alex_joni has quit 00:51:50 picnet has quit 01:00:22 robin_sz has quit 01:14:30 picnet has joined #emc 01:33:22 paul_c has quit 01:41:54 picnet has quit 01:50:55 jmkasunich has joined #emc 02:16:36 Imperator_ has quit 03:15:04 picnet has joined #emc 04:39:14 jmkasunich has quit 04:56:31 picnet has quit 05:26:54 picnet has joined #emc 09:16:15 A-L-P-H-A has joined #emc 09:45:40 alex_joni has joined #emc 10:02:54 picnet has quit 10:09:47 morning 10:21:29 morning 10:27:34 hey an0n 10:27:46 how's it going? 10:29:28 I've got a fever today 10:29:51 bummer 10:30:04 just resting and watching a movie right now 10:30:16 I'm not feeling very well too... 10:30:20 but I gotta work ;) 10:30:49 if I get a reply from the germans today I'll go to work 10:34:36 I'll probbly be working 24/7 to get this stuff ready on time 10:34:42 it's 2 weeks left on the deadline. : 10:34:44 :) 10:34:57 ouchy ;) 10:35:10 yeah, but if the manufacturer fixed the damn pwm stuff.. 10:35:13 it wont be a large problem.. 10:35:28 but I think they have to write kernel routines to prioritize it above the other stuff.. 10:36:26 bleah 10:36:30 yeah.. 10:36:30 no HW PWM? 10:36:51 no, but the cpu is at 64mhz so they've got cycles to spare 11:27:51 * alex_joni wants home 11:30:40 * anonimasu wants to work 11:30:46 :) 11:31:04 I hate being sick. 11:32:19 boring work today 11:32:19 ? 11:32:32 nah.. not boring 11:32:35 tiring ;) 11:32:38 ok 11:32:41 robot programming? 11:32:50 nah.. office work 11:32:54 oh ok 11:36:42 I am making breakfast 11:39:20 picnet has joined #emc 11:49:29 I think I catched a flu 11:49:43 :/ 11:49:57 bummer 11:50:06 too cold outside ;) 12:02:37 yeah 12:03:07 how's the weather up there? 12:04:54 it's pretty cold outside.. 12:20:16 picnet has quit 13:39:11 * anonimasu sighs 13:39:15 I cant get this axis setup right.. 13:39:22 huh 13:39:24 joint following error is all i get.. 13:39:25 what's wrong? 13:39:35 somthing with my "UNITS=" 13:39:42 ahhh... I thought you were meaning DISPLAY=axis 13:39:43 ;) 13:39:57 you're running open loop.. right? 13:40:02 only steppers, no feedback? 13:40:03 yeah 13:40:06 geckos.. and servos 13:40:15 I see 13:40:20 but no feedback to emc... 13:40:25 yes that's right 13:41:06 ok, then following errors are because emc can't output pulses so fast 13:41:12 as it's supposed to 13:41:53 thats strange 13:42:02 what is? 13:42:11 are you running emc1 or emc2? 13:42:11 that I cant output that many pulses.. 13:42:13 emc2 13:42:28 depends on how fast your rt-rate is 13:42:42 I am just using the default settings 13:43:25 trydecreasing BASE_PERIOD 13:43:34 when does the following error appear? 13:43:42 only when jogging? 13:43:46 during G0 ? 13:43:51 when jogging.. 13:43:53 during G1? what speed 13:43:56 as soon as I move the machine.. 13:43:59 dosent matter 13:44:01 single jogs? 13:44:05 try G1F1 13:44:07 always.. 13:44:11 or G1F.1 13:44:16 what units are you using? 13:44:28 I am using continous jog.. 13:44:37 when I am testing it's inch.. 13:44:40 but I should be running mm 13:44:53 ok, for jogging you have a slider called joint speed (axis speed) 13:44:56 smthg like that 13:45:02 yeah, I know.. 13:45:16 dosent matter if i increase/have it at the default value 13:45:20 try decreasing the value 13:45:33 I get the error as soon as i move the axis 13:45:38 you say you have X and Y set up the same way? 13:45:40 yes 13:45:44 A-L-P-H-A has quit 13:45:48 in the .ini file? 13:46:01 UNITS=38023 13:46:10 hmmm 13:46:11 .38 13:46:22 the only difference is the backslash.. 13:46:33 UNITS = 0.03937007874016 13:46:48 thats steps per inch.. 13:46:52 backlash inside .ini ? 13:47:03 BACKSLASH= 13:47:07 yeah 13:47:19 I don't think that works ;) 13:47:25 heh ok.. 13:47:35 check core_stepper.hal 13:47:37 or no wait.. 13:47:38 it does work.. 13:47:45 it takes up the backslash before moving.. 13:47:51 then it errors.. 13:47:53 a lot of stepping parameters are now in core_stepper.hal 13:48:05 hmmm.. might be a backlash-problem 13:48:16 if you set backlash to 0 does it work? 13:48:19 no 13:49:16 hmmm.. you need to ask jmk 13:49:23 he'll help you set the axis up 13:49:31 did you try to run it without emc? 13:49:42 without? 13:49:59 yes, only from HAL 13:50:07 no I have no clue on how to do that 13:50:26 http://www.linuxcnc.org/Hal_Introduction.pdf 13:51:12 picnet has joined #emc 13:51:43 the strange thing is that it works with the default UNIT settings in the ini 13:52:10 what is that? what value? 13:52:47 rayh has joined #emc 13:53:29 UNITS = 0.03937007874016 13:54:09 hello ray 13:54:20 ok, and what's the value it doesn't work with? 13:55:10 Hi guys. 13:56:13 how are you? 13:56:42 an0n: units=38023 doesn't make any sense 13:57:02 hm, I was told that units was steps per inch.. 13:57:03 :) 13:57:08 or that's the way I understood it.. 13:57:15 not UNITS 13:57:22 0.000065748031" per step 13:57:25 INPUT_SCALE 13:57:36 and OUTPUT_SCALE 13:57:43 but for emc2 those don't work 13:57:59 and you need to adjust the value inside core_stepper.hal 13:58:07 setp stepgen.0.position-scale 5080 13:58:20 replace that with 38023 13:58:32 same for stepgen.1 (Y-axis) 13:58:37 stepgen.2 (Z-axis) 13:59:08 ah.. 13:59:16 that makes more sense... 13:59:34 UNITS is the base value for the axis units (to adjust mm or inch) 13:59:39 UNITS=1 (mm) 13:59:49 UNITS=0.03937... (inch) 14:00:04 * anonimasu sees hope again 14:00:14 position-scale is then the scale based on steps/user_unit (specified by UNITS) 14:00:49 how many steps do you need to travel an UNIT 14:01:07 ah, then I need to calc this into mm instead.. 14:01:24 I'd run UNITS=1 14:01:25 (all over the emc.ini) 14:01:29 default = mm 14:01:30 etc. 14:01:36 and re-calc my scale to be steps per mm 14:01:41 yup 14:02:15 thanks :) 14:03:20 yw 14:03:46 * alex_joni giggles 14:03:51 38023/2500=mm then 14:03:52 you had some really big UNITS 14:04:04 what's 38023? 14:04:09 and what's 2500 ? 14:04:11 the steps per inch 14:04:30 I wonder how you calculated that 14:04:39 2.5/0.000065748031(inches per step) 14:04:54 start over ;) 14:05:04 how many pulses/rev at the motor? 14:05:06 200? 14:05:26 400 14:05:33 ok.. 400 14:05:43 how far does the axis move by one turn? 14:05:45 4:1 to the screw 14:05:52 5mm screw 14:07:13 so 4 turns move 5 mm? 14:07:18 yes 14:07:26 16000 pulses move 5 mm? 14:07:34 1600 14:07:46 1600 pulses move 5 mm 14:08:00 320 pulses/mm 14:08:05 right? 14:08:07 yes somthing like that 14:08:27 if I remember it correctly its 0.0039 per step 14:08:31 ok.. there you have it 14:08:37 don't calculate in inch ;) 14:08:39 0.003125 14:08:43 you'll end up using rounding 14:08:49 and that's bad 14:08:54 yes 14:09:00 320 is the value you need to enter to core_stepper.hal 14:09:34 the z axis will be tricky... 14:09:39 since I dont have any specs on it.. 14:09:50 you need to measure that 14:09:55 I just moved it until it went 0.01 14:09:58 same motor? 14:10:10 nope stepper, the gecko I had for that axis died.. 14:10:19 bummer 14:10:26 what geckos do you have for XY? 14:10:29 g340 ? 14:10:33 yeah 14:10:53 you need to make sure you don't have the multiplier set above 1x 14:11:03 I have the multiplier set to 5 14:11:10 5x 14:11:10 set it to 1 14:11:17 that will take away my speed.. 14:11:20 or the calcs won't be ok 14:11:23 no it won't 14:11:30 speed will come from emc 14:11:41 or leave it at 5x, but devide 320 /5 14:11:54 -> 64 pulses/mm 14:11:56 the encoders are 1000counts/rev 14:12:04 which becomes 2000 at the gecko.. 14:12:07 in quadrature 14:12:16 ahh.. ok 14:12:24 so 400 / rev takes that into account 14:12:27 yep 14:12:35 that's 2000/5 14:12:41 really? :P 14:12:45 yeah 14:12:46 :D 14:12:57 * alex_joni writes that down 14:13:01 ^_^ 14:13:26 my math is so bad.. 14:13:35 :b 14:13:53 I'll be back in a little bit, going to test this at the machine 14:14:07 cool 14:14:11 I might go away 14:14:11 :D 14:14:22 that reminds me of my favorite linux error message 14:14:23 ok 14:14:33 "You don't exist! Go Away!" 14:14:37 haha 14:14:37 lol 14:14:43 I like that message 14:14:43 I got that once ;) 14:14:59 it's an error if access from an unknown PID is made 14:16:26 I love the message screen gives you when you kill a screen with somone inside.. 14:16:37 "the dungeon collapses, and you die" 14:16:41 or somthing like that 14:17:15 lolol 14:18:04 my favorite quote: In a World without Walls and 14:18:04 Fences, who needs Windows and Gates? 14:22:09 Nice post Alex. 14:23:31 the one on the devlist? 14:24:31 still didnt help.. 14:24:58 :( 14:25:00 an0n: what's wrong now? 14:25:12 same thing 14:25:19 joint following error 14:25:55 hmmm.. do you have DEBUG set? 14:26:20 I think so 14:26:31 I get lots of messages in the console 14:26:33 ;) 14:29:36 can you record the output? 14:30:10 or better, can you send me the ini and .hal files? 14:30:20 alex_joni: Yes the dev list. 14:30:32 I could do that although later this weekend/tonight 14:30:49 the fever's going up again so I am going to lay down 14:31:28 ok 14:31:40 you could start with a new one (from CVS) 14:32:01 and change only the position-scale 14:32:01 did that yesterday :) 14:32:03 yeah 14:32:13 I'll try that later I have the cvs version on the cd in the box 14:32:26 just untar/compile and try again 14:33:13 coo 14:33:26 or just untar the config files 14:33:33 and leave the rest untouched ;) 14:34:08 yeah 14:36:38 anyways bbl 14:36:48 hope you can go home soon 14:36:49 ok 14:36:53 I will 14:37:02 later I'll go to college and install a debian ;) 14:37:08 so I'll be online later 14:37:18 it's finally dark enough for me to use the projector.. 14:37:31 coo 14:37:31 been waiting for the sun to go down.. 14:38:21 ah good, I'll try changing that later, and if I get error messages i'll save all of the files so you can have a look at it when you get time 14:38:59 ok 14:39:11 mail them, and I'll take a look 14:48:58 * alex_joni gone home 14:49:01 alex_joni has quit 15:01:38 rayh has quit 15:19:10 picnet has quit 16:03:01 picnet has joined #emc 16:05:17 rayh has joined #emc 16:45:26 A-L-P-H-A has joined #emc 16:45:28 :( 16:45:41 $1066USD for a stepper driver for my stepper motor that I have. 16:45:43 ouch. 16:45:49 !!!OuCh!!! 16:52:43 5 phase? 16:53:26 alex_joni has joined #emc 16:53:31 5 phase, pentagon arranged winding. Patented by Oriental Motors. 16:54:21 evil bastards. They don't even have papers on how to make one a driver... BUT they do have papers on the two phase. 16:55:01 Anyone got any nema24 sized stepper motors they want to sell? 16:59:06 acemi has joined #emc 17:01:40 picnet has quit 17:03:45 A-L-P-H-A_laptop has joined #emc 17:13:30 g'evening 17:13:34 an0n: around? 17:13:43 dunno 17:13:48 but good afternoon. :) 17:14:04 hello alpha 17:14:10 * alex_joni is installing debian 17:14:33 <-- looking for Nema 23 stepper motor, or "servo [nema 23]+ driver"... 17:15:02 paul_c has joined #emc 17:15:50 hello paul_c 17:15:59 Hi Alex 17:16:04 hey 17:16:07 hi 17:16:09 17:16:29 A-L-P-H-A: What part of the world are we shipping this motor to. 17:16:36 Toronto, Canada. 17:16:47 you need a special anti-freezing version ;) 17:16:50 so from the US, it'd be best to ship via Priority. 17:17:06 USPS is fine. 17:17:09 I've got some little ones 100in/oz or so. 17:17:27 that'd be perfect... I'm doing driving a 100:1 worm. 17:17:42 I'm wondering if I could even use smaller. 17:17:45 hm. 17:17:47 4 wire and 8 wire. Not very strong but good enough to test. 17:18:10 let me see what I've got... I think I've got 6 tiny TINY steppers... like 1.5" frames. 17:18:13 Got some old floppy drives laying around. There is a stepper and screw in there. 17:18:18 they're 55oz/in. 17:18:28 5-1/4"? Maybe. 17:18:42 3.5" I want, and still sometimes use [for turbocnc] 17:18:48 I thought about building a mill from floppy drives. 1" motion in three directions. 17:19:41 Hi Paul 17:19:46 Wow, Dan Mauch has some cheap prices. 17:21:16 hi guys 17:21:31 Hi Dan. 17:22:25 I'm going to take Paul out to the surplus place today 17:22:48 he says he can't lug any more stuff home on the plane, but we can always just look .... 17:23:03 it's called a shipping container. :) hehehe 17:23:17 Are we talking the boeing surplus store out in seattle? 17:23:29 or well, washington state at least. 17:23:34 no, SurplusGizmos in Hillsboro, Oregon 17:24:11 Oh, I thought he went to Washington state. 17:25:23 only as far as Portland 17:26:08 wanted to get some of the Sensoray cards to do driver for them.... 17:26:25 Somebody used that vulnerability and got to my netscape... 17:27:32 onlything good on Dan Mauch's site worth buying is maybe that tach, and his steppers... everything else is overpriced. sad. oh ohwell. 17:27:45 SteveStallings has joined #emc 17:28:20 Morning Steve 17:28:28 hi Paul 17:28:44 Car is covered in ice this morning... 17:29:09 drive south 17:29:15 haha. 17:29:40 I had to salt my patio stone pathway today... I nearly slipped. 17:29:46 want to go back to Yosemote on the way south. 17:31:08 I missed the discussions on HMI & emc 17:31:25 could someone give me a recap ? 17:31:34 so did I, summary? 17:31:44 summary: 17:32:02 we (rayh, robin_sz, myself) talked a bit about HMI 17:32:30 and one of the conclusions is to create a layer (above emcsh for tkemc) 17:32:52 which contains all of the possible status/commands to and from emc-components (task, motion, io, etc) 17:33:25 and the GUI creator simply links one of those (they were called bricks, and the whole layer was called a wall) bricks 17:33:45 the brick defines the type it is, some default data, min/max values, etc 17:34:10 and the GUI creator (at a later stage even a user) simply selects those and puts them on a blank gui 17:34:28 for example there is a brick for speed_override 17:34:36 which contains the command for emc 17:34:38 min_value 17:34:41 max_value 17:34:51 status (value from emc) 17:35:32 Sounds like an OOPS model for tcl/tk 17:36:32 We are thinking of generalizing enough so that any kind of interface could use the same set or subset of status variables and commands. 17:37:07 Nice job Alex. 17:37:15 kinda like adding another layer of abstraction on top of NML ?? 17:38:26 still sounds like every change in the guts of EMC will require changes in NML and everything that talks to NML 17:38:48 steve: we also talked about adding generic messages all over emc 17:38:52 I posted a note a bit ao to dev with a link. Let me get it. 17:39:20 those messages (deep in the emc-guts) can then be adjusted by the user without recompiling 17:39:23 A-L-P-H-A_laptop has quit 17:39:30 I had a quick read of the pdf Ray.. 17:39:42 www.isd.mel.nist.gov/documents/michaloski/wac2000hmi.pdf 17:39:46 k. 17:40:33 After reading it. It seems to me that we include this info in a module much the same as hal includes stuff. 17:41:11 When that mod starts, it exports it gui info to some sort of, in their terms a catalog or dictionary. 17:41:29 * paul_c had some thoughts on NML messages..... It would be usefull to have some generic NML messages rather than one for each func. 17:42:07 Yes. Alex suggested that yesterday. In connection with the work he is doing on CL 17:42:21 it can be used for that too.. 17:42:43 actually I was thinking about a generic function (with a subtype possible) 17:42:54 but the subtype selection to be made without recompiling 17:43:01 damit - I need to be around for the Sunday meetings... 17:44:06 what's the average/normal torque from an stepper ripped from a diskdrive? 17:44:31 We could handle this issue on a wiki page. 17:44:53 or at least provide a summary of irc. 17:46:30 paul_c: when will you be back? 17:46:42 Feb 18th 17:46:58 allow a day or two to recover from jet lag 17:47:40 that means you'll be around for the next weeks sunday meeting... 17:47:49 I think we can pospone the talks till then 17:47:58 maybe think about it, to get things clearer 17:48:47 Sounds good to me... 17:51:41 In the meantime, whats the status with CL, emc, & comms ? 17:52:34 * rayh is wondering how the current work on CL might be applied to emc1 as well as emc2 17:57:17 If CL had a simple NML interface, there is no reason why it couldn't work with emc1 17:57:41 CIA-7 has quit 17:58:26 right now it hasn't 17:58:32 Right. The work that Alex had done is on all com through the hal. 17:58:33 I just added hal-pins to CL 17:58:57 but NML interface is needed too 18:00:19 CIA-temp447 has joined #emc 18:00:23 CIA-temp447 is now known as CIA-7 18:00:36 paul_c: right now I did a quick hack to test if it's possible to link CL to HAL 18:00:41 and it works, 18:02:37 I had been thinking along the lines of having CL "pins" connected to NML messages 18:03:19 Both ways will work. 18:03:37 picnet has joined #emc 18:03:44 The nml approach allows for distributed processing. 18:03:46 right 18:04:02 The HAL approach for rt based logic in CL. 18:04:13 the HAL approach simply allows you the use of existing (future) HAL-drivers 18:06:22 and RT based logic 18:30:51 rayh has quit 18:34:56 paul_c has quit 18:36:31 SteveStallings has quit 18:39:24 picnet has quit 19:04:51 * anonimasu yawns 19:36:20 robin_sz has joined #emc 19:37:34 meep 19:50:34 rayh has joined #emc 19:53:23 per: You around? 19:53:26 pemmet: you around 19:53:48 alex_joni has quit 19:57:14 Mer has joined #EMC 19:57:20 Mer has left #EMC 20:04:10 picnet has joined #emc 20:12:27 CIA-7 has quit 20:12:29 CIA-temp177 has joined #emc 20:12:31 CIA-temp177 is now known as CIA-7 20:20:37 hehe, fun EMC,GPL discussion on Geckodrive forum 20:20:40 paul_c has joined #emc 20:20:45 hi paul_c 20:21:16 Yo. 20:21:24 and where are you today? 20:21:31 seattle? 20:21:40 Portland 20:21:46 maine, nice. 20:21:54 Oregan 20:21:58 is it? 20:22:00 oh well 20:22:24 oh well, thats my US geography goen then 20:22:44 nice little EMC/GPL discussion there on the geckodrive list 20:23:12 will look at that when I get home 20:23:28 is that soon? 20:23:37 next week 20:23:48 did you leave the wrinkly with plenty of food? 20:24:14 she can fend for herself 20:24:30 or I can send food parcels over. 20:24:32 thats what I said about my goldfish ... 20:24:56 anyway, ive been having G2002 fun :) 20:25:13 sadly our SILLY_FUNCTION_NAMES have infected that project too :( 20:26:22 You have the code - Change it. 20:26:41 yeah, I wnated too ... but hes about a year behind on the EMC interp or more 20:27:08 he wants to keep it the same so he can diff agisnt emc interp, without too much noise 20:28:10 The emc1 interp isn´t going to be developed much more... 20:28:35 Most of the work that I am doing will go in to the emc2 version 20:28:40 yep 20:28:52 I've poitned this out 20:29:06 not pointed ? 20:29:16 I'll have to check 20:29:30 the EMC wiki has gone well 20:29:51 fat fingers, small keyboard. Or just too much wine ? 20:29:57 hic. 20:30:01 lack of care 20:30:03 ^_^ 20:30:54 So what was the response to the ¨poitned" comment ? 20:32:10 norra lot. I think he used the EMC1 codebase as the original source 20:32:38 dunno how hard it would be to patch agaisnt EMC2 20:32:52 hes doen a *lot* of work on it thats for sure 20:33:08 ive found a few bugs, and even patched a few 20:33:59 the C I can hack, the .asm ... not really anymore 20:34:59 Z80 code ? 20:35:35 z80/rabbit 20:35:38 much the same 20:39:09 it does work nicely though, apart from a few minor things .. 20:42:43 how smart is the planner? segment blending and stuff like that? 20:48:34 its quite clever ... 20:48:48 there are effectively three planners ... 20:49:15 you mean three to choose from? 20:49:26 no .. three running in the system 20:49:29 one per axis? 20:49:33 no 20:49:38 three layers 20:49:40 oh 20:49:47 sounds pretty complicated for a little microcontroller 20:50:03 and its got the EMC interpreter in there too rememebr 20:50:26 the planners are quite simple 20:50:39 the first is just a basic move planner 20:50:53 the second layer is a moving average queue smoother 20:51:48 the third is a bit nebulous .. but basically is a short moving average queue to provide a bit of jerk limiting 20:52:10 whatver, the result is smooth motion 20:59:06 adem has joined #emc 21:23:39 * paul_c is heading off to scour the local surplus store(s) 21:40:45 picnet has quit 21:48:32 rayh has quit 22:10:53 there is Synergy CAD/CAM in BDI. is this a demo version of Stnergy? 22:12:06 alex_joni has joined #emc 22:12:21 hello again 22:16:01 picnet has joined #emc 22:17:04 hi alex_joni 22:17:19 hey alpha.. 22:17:24 did I miss anything? 22:17:54 nope... just scanned the messages, nadda. 22:18:02 heh 22:18:17 * alex_joni installed a debian today 22:18:34 I think I'll make a tiny stepper driver. :) Half stepping only... but hey! :) it'll be on the cheap... just need to have someway to power it. 22:18:50 alex_joni, you do AVR programming right? 22:20:53 hmm... if I have a 4VDC 1.2A stepper motor... I think I'll need to give it hmm... how many volts to make it spin decent. 22:20:57 16+. 22:21:05 so I'll go 24VDC. 22:23:27 half stepping is pretty straight-forward to do 22:27:26 jepler has quit 22:31:39 jepler has joined #emc 22:31:58 alex_joni, got 8 of them. :) http://www.fairchildsemi.com/ds/TI/TIP121.pdf 22:33:02 my connection is really flooded 22:33:10 I'm on dial-up here 22:33:12 :( 22:33:20 hmm... how do I wire that to a 6 wires with the dakeng project. http://www.dakeng.com/u2.html 22:37:03 you don't 22:38:59 how many phases does your motor have? 22:39:50 2 22:40:29 I just pictured it in my head. 22:40:38 4 wires, [series or parallel] 22:40:40 2? 22:40:42 ahhh 22:40:45 ok 22:40:50 then you can connect the dakeng 22:40:59 that's basically a 4-bit counter 22:41:25 yeah, 6 wires, but only use 4... [series or parallel] 22:41:38 just had to picture it in my head. 22:42:02 gotta remember how it's coiled. 22:42:24 dang, I think my batter for my mouse is going to die soon. 22:42:30 second time today I needed to reconnect it 22:42:31 lol 22:42:39 battery 22:43:11 acemi - The Synergy on the BDI is the full version 22:45:18 hmm... nice 22:45:23 thanks websys 22:45:28 yw 22:50:10 alex_joni, if I'm using the tip121, I don't need that diode that the DAK schematic has do I? [right where the NPN transistor is] 22:52:54 you don't need it 22:53:19 it's integrated in the tip121 22:55:07 jepler_ has joined #emc 22:55:42 jepler has quit 23:02:23 jepler has joined #emc 23:02:23 jepler_ has quit 23:15:04 * alex_joni goes to bed 23:15:06 night 23:19:24 alex_joni has left #emc 23:32:08 picnet has quit
