I also want to do this with Linux. Am i dreaming? 06:28:25 yes 06:28:25 I 06:28:25 I've looked, there's not any really really good CAD for linux 06:28:41 what abour brl-cad? 06:28:41 unless it's hiding really well. 06:29:16 I've not used that one. 06:30:08 there's a placeonline that will make parts from your models, if I could remember thier url.. 06:30:37 yeah i really need parametric 3d solids i think since polygonal modelling won't have the accuracy - i could model all the parts in blender, but accuracy i think would be an issue 06:32:10 if thats not the case, it could be an option for me... 06:32:55 well, let me ask another question - say i have a .DXF of a part - what is involved in turning that into a CNC-millable object i.e. G-Code? 06:33:51 disclaimer: I'm a newbie too. 06:33:52 hehe ok :) 06:33:52 but you need CAM software, it actually plots tool paths 06:33:54 and "cheap" for cam means its under a grand 06:34:17 but if you're hiring out the milling, they'd handle the cam 06:34:32 why a rotary engine, just for fun? 06:34:38 yeah pretty much 06:34:43 i'm a bit of a rotor-head 06:34:53 in that i own an RX-7 and a small sachs rotary 06:35:24 heh, ok 06:35:24 which i plan to put in a scooter 06:35:24 but thats another story 06:35:24 *schwing* 06:35:37 <-- vespa nerd 06:35:49 yeah i'd like to put it in a vespa.. 06:36:46 * bill20r3 thinks 06:36:46 a lammy would probablly be easier. 06:37:19 has this idea got past the "you know what would be cool..." stage? 06:37:38 yeah anything i do i'd basically create a custom subframe/swingarm and use a bike gearbox/chain drive - the vespa would be just the body shell and front forks really.. 06:37:39 not exactly, i take delivery of the engine tomorrow 06:37:52 a vespa engine you mean? 06:38:02 no, the rotary 06:38:53 the previous owner fitted it with electronic ignition, a motorbike carb and a turbocharger.. its kind of begging to be put into a scooter ;) 06:39:04 oh, I thought you meant to build one. 06:39:17 i do want to build one 06:39:35 that would be another one 06:39:42 i told you i was a rotorhead ;) 06:40:13 heh 06:40:27 you allready have a scooter frame? 06:41:17 if when it gets done mail me some pics to bill@scoot.net 06:41:23 and I'll love you forever 06:41:31 k, will do ;) 06:42:04 what is the engine you're getting tomorrow from? 06:42:50 its a sachs engine - i think they used them to power outboard motors 06:44:24 http://search-desc.ebay.com/sachs-rotary_W0QQfkrZ1QQfnuZ1QQftsZ2QQxpufuZxQ5A1 06:44:27 that kind? 06:45:44 could be.. this one is about 150cc 06:45:53 definitely same manufacturer 06:47:11 sachs made some mopeds too, you could do a sachs-sachs 06:47:41 hehe i could i guess.. they make some pretty cool looking bikes like the sachs madass 06:48:00 totally 06:48:22 i saw one of those the other day but its pretty expensive and seems to be rather underpowered 06:48:23 I vote lammy chopper. 06:48:27 the 50cc? 06:48:32 yeah, the 50cc 06:48:33 I think there's a bigger one too. 06:48:41 it's like naked bike, in scooter form 06:49:54 i have a little 50cc pgo (taiwanese) that i'm also wanting to hot up, but fitting the rotary would be a problem since its my daily rider 06:50:15 it's a smallframe, or P sized? 06:50:39 pick up a honda elite to ride.. 06:51:14 its a PMX-50.. quite large for a 50cc scooter... just needs an expansion chamber really 06:51:19 I have an et3 06:51:24 nice 06:51:24 (among others) 06:51:42 i'd like a 'proper' vespa/lambretta but too many $$$ 06:52:10 with 50-special parts on it, the square headlight and tiny tail light 06:52:10 yeah, they're not cheap anymore 06:52:13 cool.. i gotta go out to pick up dinner.. will be back in 15 minutes or so if youre still here 06:52:34 http://scoot.net/scooterist/Bill_in_SLC 06:52:36 k 07:50:06 giacus_afk has quit 08:48:18 IkeKrull has quit 10:40:26 cncuser has joined #emc 10:40:31 hello :) 10:41:00 the hangs i had where related to some buggy patched kernel of mine. 10:41:49 anyone ever seen that one ? : ImportError: libnvidia-tls.so.1: cannot handle TLS data 10:42:27 the minigl import by axis leeds to this on my box :( 10:42:34 i blame nvidia 10:56:15 hmm, when i use softwarerendering it work. bad bad nvidia. 11:01:23 hmm 11:01:53 i also still see the graphical plot of axis wrong scaled when running 11:02:02 got emc2 and axis form the last hour 11:07:41 morning 11:07:52 morning alexjoni 11:08:12 what's wrong with the scale? 11:09:11 the "white lines" on the screen would not get painted red. ninstead the cam job viewn in white is ploted in red very small in a corner 11:11:01 hrmm... 11:11:03 running G21 ? 11:11:12 can you make a screenshot? 11:11:20 and give me the program & ini ? 11:11:21 yes 11:11:59 this is latest AXIS?

Not the best. 16:28:00 the basic design is pretty simple, it's the FPGA code that's hard to develop 16:28:12 but there's FPGA source in the M5I20 EMC driver 16:28:19 why are fpga's so icky? 16:28:40 the G-Rex is also geared toward step generation, not analog control 16:28:55 FPGAs aren't icky, they're just so flexible, it's hard to define what they should 16:28:57 do 16:29:04 it's the restrictions that get you 16:29:11 (ie, defining them :) ) 16:29:26 Tom k is also using a moving average...have to get him away from that 16:29:54 moving average is just a second-order FIR filter 16:30:37 a rectangular convolution. Run a trapezoidal wave through one. nasty. 16:31:31 hmmm, it's not a convolution, because you don't have a second set of coefficients "sliding" over the input waveform 16:31:58 unless you consider the window itself to be a positive step function, then a negative one superimposed 16:32:58 I always considered the term "moving average" as the convolution of the signal with a rectasngular window 16:33:20 that's what tom k is doing anyway 16:33:30 ok - that makes sense 16:34:12 It makes for less than ideal paths anyway 16:34:42 the ideal FPGA basd controller would be something like the Mesa card, but with the I/O protection on the G-Rex, and a bit of analog on the board 16:35:20 there are even FPGAs with analog sections on them now ( O_O ) 16:36:45 well an a/d converter would be hella useful 16:37:12 A/D, scaling, plus other stuff, all reconfigurable 16:37:23 32 channel mux 16:37:38 what do you think about the fpga/processor combos? is that just a gimmick or is it really useful? 16:38:27 do you mean the FPGAs that have processor cores in them, or the embedded processor cores that you can include as part of the logic? 16:38:50 the fpga's with cores on the same chip 16:39:47 actaully, I'd say it's pretty useful in either case, but the IP cores are more cost-effective (but not as fast, in general) 16:40:17 think about an IP stack - that's not really a logic function, though it could be done in "hardware) 16:41:00 having the checksums / CRCs accelerated by some FPGA fabric is excellent, but wasting space on e.g. routig tables might not be the best thing 16:41:07 routing 16:41:11 i'm talking about an FPSLIC 16:42:29 that's actaully more expensive than a high-end FPGA 16:42:39 they're cool though 16:43:43 thats one thing about fpga's.. the high end ones sure are pricey :) 16:44:00 yeah - I'd have a har dtime spending $9500 on a single chip 16:44:04 hard time 16:46:28 hey running on wood heat again...one stack dried enough to burn 16:46:49 hate giving 500-$1000/mo for natural gas 16:48:02 the shop is all NG though 16:48:22 might get one of those outside wood fired boilers 16:48:38 then I could heat all buildings with one 16:48:52 and have it thermostatically controlled 16:50:46 * fenn hates being cold all the time no matter how much money goes to the gas company 16:51:03 you could even get a chiller, and have combined cooling in the summer 16:51:15 yeah 16:51:30 I'm just sick of these high bills 16:51:32 just run the pipes underground 16:51:47 in the summer that is 16:51:50 I can pay it...it's just the principle. 16:51:57 and 16:52:12 I have unlinitetd wood supplies pretty much 16:52:13 make a passive solar design then when you re-build 16:52:33 less work overall 16:52:46 or, you could put up a satellite, and beam microwave energy down 16:52:50 ha 16:52:52 that would be direct heating in the winter 16:53:22 just build a maxwell demon 16:53:53 I have to spend a good bit to keep some heat in the shop at all times 16:54:06 or move to Pennsylvania, where the coal mines are burning 16:54:10 If I power it down everything cold soaks 16:54:25 then turn on the heat...all the cast iron sweats 16:54:37 yeah - tell me about it 16:54:42 you should see my garage 16:54:54 lots 0' sweaty iron 16:55:02 unvented gas heater? 16:55:09 they make a lot of water 16:55:29 no heater (other than the portable Kerosene one), Vermont 16:55:40 yikes 16:56:00 it it werent for the coolant and metal chips, I could sell bottled water 16:56:21 today was supposed to be snowy, but so far none 16:56:56 it was damn cold over here last night 16:57:01 -15 or so (C) 16:57:21 mountain tops are getting some snow...cold too 16:57:25 http://ils.unc.edu/parkproject/webcam/webcam.html 17:00:21 anyone have any experience with the Centent stepper drivers? 17:00:55 sorry not that brand... 17:02:56 they claim a 'Anti-Resonance' feature, there's some used ones on ebay I've bid on. 17:03:41 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7585877453 is a set of 5 Appli3ed Motion drivers at $130 too, I may bid if they dont get too high. 17:06:24 looking 17:07:39 here's the Centent's: http://www.centent.com/cn0142.htm 17:09:06 looks like a gecko to me 17:09:10 just a different package 17:09:33 yeah, I did read something that said they were the same. 17:09:47 maybe an older version, I guess. 17:09:52 yup 17:09:55 aren't they atually more expensive than the Geckos? 17:10:13 "Look on e-bay for some drives by the name of OMC or CENTENT. 17:10:14 They are Older Gecko drives sold under another name. I know a guy who has several sets of them." 17:10:15 probablly if they're new, but I'm bidding on used ones. 17:10:25 SWPadnos: 5 for 130$ seems reasonable 17:10:27 ;) 17:10:38 anyone know the difference between the gecko G201 and G202? 17:10:43 that is cheap, but the drives in that acution aren't the centent ones 17:11:10 besides "$20" 17:11:13 the filter cap is built into the G202, plus I think you can't kill it by shorting motor leads, disconnecting the motor, etc. 17:11:16 the centent's are in another auction. 17:11:57 ahh, so no additional features that'll affect operation once it's set up. 17:12:05 yep - the G202 has some of the features of the "vampire" drive tha Mariss has designed (an FPGA based drive) 17:12:06 yup, the G202 is the one with protection on shorts 17:12:19 yes, if a stepper coil shorts, you'll lose a G201, a G202 will shut down 17:12:27 there is a smarter G201 (G210 I think), which has a multiplier 17:12:41 I almost ordered some the other night, until I realized maybe my judgment wasn't the best at 2:30am. 17:12:52 bye 17:12:53 yep - the G210 is a G201 + step multiplier, the G212 is the G202+step multiplier (G901) 17:12:54 cncuser has quit 17:12:59 bye cncuser 17:13:05 byee. 17:13:17 SWPadnos: any idea what's different between G901 and G902? 17:13:30 I KNOW what they are used for.. 17:13:36 it's some detail about which drives they get plugged into 17:13:45 but I'm wondering if a G902 might fit into a G201 17:13:55 I have the G902 in a G340 (DC) 17:14:15 well - the website says that the G901 is for the stepper drives, and the G902 is for the servo drives 17:14:26 yup, I know that 17:14:48 lerman has quit 17:14:54 * alex_joni decides to ask mariss 17:15:09 it's just some detail about the polarity of the inputs or something - I think the question was answered on the Gecko list in the past year or so 17:15:09 lerman has joined #emc 17:19:33 it was? couldn't find it 17:19:45 hmmm - one sec 17:20:54 here it is: 17:21:13 Simple. The G901 / G902 runs on 5VDC. The logic in the G201 works on 17:21:14 +12VDC while the logic in the G320 is +5VDC. 17:21:16 To accomodate both, the G901 carries a 78L05 +5VDC regulator. 17:21:17 For the G201 step motor drives, it's used to bring the +12VDC down to 17:21:19 +5VDC for what's required for it to operate. 17:21:20 For G320s, whose logic runs at +5VDC anyway, this regulator is 17:21:22 twisted out and thrown away. 17:21:23 got un url? 17:21:24 Otherwise there is no difference. 17:21:25 Mariss 17:21:29 an 17:21:33 the thread title is "g902 manual", from 12/2/2004 17:21:41 nope - I just searched local messages 17:21:53 ahh.. 17:22:07 you could search the archive for both G901 and G902 17:23:01 that's dec.02 ? or 12.Feb ? 17:23:10 heh Dec 2 17:23:28 thanks, found it http://finance.groups.yahoo.com/group/geckodrive/message/3802 17:23:35 cool 17:23:55 just a detail about the internals of the units - 12V or 5V supply coltage 17:24:25 guess I need a 7805 ;) 17:24:32 heh 17:24:42 or some really good internal heatsinks :) 17:25:20 not sure if the chips won't barf 17:25:42 if there are TTL chips in there, running them at 12V might be problematic ;) 17:25:49 true 17:25:52 btw, you had a different name back then :) 17:26:07 From: Stephen Wille Padnos 17:26:36 too many padnos's 17:26:53 not so different 17:27:03 Wille != Willie 17:27:16 Willie is wrong - I never spell it that way ;) 17:27:24 really? 17:27:38 but no matter how many times I type it, it still gets misspelled about 90% of the time 17:27:45 (by others transcribing) 17:27:59 I get mail for Stephen Willlie Padnos even :) 17:28:22 (or Sleplen Pedros, or Stephen Pegmos, or ... ) 17:28:50 fenn: a few Padnos'es over here: http://www.geocities.com/hewlettalumni/wherenz.html 17:29:01 one of these days, I'll fix the AUTHORS file, to make the W into Wille (since it's not a middle name) 17:29:08 so it's Wille or Willie? 17:29:28 ok, Wille I guess.. 17:29:33 there's a Psdnos Stell company in Michigan, and there's even a Padnos college (or a building at a college) 17:29:37 I always thought you says Willie 17:29:41 steel, not stell 17:29:49 geez 17:29:56 Padnos Steel - there we go :) 17:30:32 here we go - the Padnos school of Engineering: http://www.gvsu.edu/engineering/ 17:30:51 http://gvsu.edu/pcec/ 17:30:58 http://www.js.spokane.wa.us/kimerav4n2/padnos.htm 17:31:01 agh everywhere i look there's FIRST robotics 17:31:16 Self-Fertilization ? 17:31:18 that's my stepsister :) 17:31:26 SWPadnos: really? 17:31:29 half-sister - whatever 17:31:31 yep 17:31:38 lot cuter than you 17:31:42 yep 17:31:43 you're not related :P 17:31:44 * fenn cackles 17:31:46 but not in person :) 17:31:49 * alex_joni laughs 17:31:50 same Father 17:31:56 if that counts 17:32:42 I guess she got the "weirdo artistic" genes ;) 17:32:56 how about you? 17:33:03 he just got the weirdo genes 17:33:14 I got the weirdo analytic / scientific genes 17:33:26 I'm the mad scientist type of my generation 17:33:45 heh.. 17:33:50 so how about Wille 17:34:00 where does that come from? you said it's not a middle name 17:34:06 that's my wife's maiden name. we both took both names when we got married 17:34:15 coo 17:34:36 yep. lots of people have never heard of anyone doing that 17:34:37 how'd you decide who's name goes first? 17:34:57
