[21:20:52] <Jacky^> cradek: are you ?
[21:20:57] <cradek> yes
[21:21:04] <Yuga> are you?
[21:21:17] <Jacky^> already seen this ?: http://vinvin.dyndns.org/projects/scanner.html
[21:21:36] <Jacky^> seem very simle
[21:21:42] <Jacky^> simple*
[21:21:54] <cradek> no, but I've wondered about doing this before
[21:22:19] <Jacky^> I'm looking for a good project
[21:22:21] <Yuga> what cad program u ppl use?
[21:22:33] <cradek> autocad r12
[21:22:37] <cradek> for dos
[21:22:51] <Yuga> no linux based one's?
[21:23:18] <Jymmm> cradek : DOS?! I though i was the only one that still used DOS
[21:23:38] <cradek> I run autocad on freedos in qemu on linux
[21:23:50] <Jymmm> oh, heh
[21:23:54] <Jymmm> qemu ?
[21:24:00] <cradek> it's just more convenient that way. I don't have any problem with using dos when it's appropriate
[21:24:13] <cradek> qemu is a virtual machine (free)
[21:24:37] <Yuga> so there isnt realy a good linux program out there?
[21:24:48] <Jymmm> cradek replacing dosemu I suppose?
[21:25:25] <cradek> Jymmm: dosemu isn't a virtual machine, it's a program that tries to provide dos services well enough to run dos programs
[21:25:30] <cradek> totally different programs
[21:25:38] <Jymmm> ah, ok
[21:25:47] <cradek> qemu is more like vmware, but free of course
[21:25:57] <Jymmm> ioh, it can do 2k too
[21:26:33] <Jacky^> I tried latest snhapshot of qemu. I can see it's hard..
[21:26:43] <cradek> hard?
[21:26:45] <Jacky^> at least installing win2k
[21:26:53] <Jymmm> ok, so pull out the dual G4, toss on linux, then qemu and xp =)
[21:26:56] <cradek> I have installed win2k once successfully
[21:27:02] <Jacky^> it won't accept update and service pack
[21:27:16] <Jacky^> no 3d support..
[21:27:16] <cradek> ah
[21:27:20] <cradek> (I'm not a windows user)
[21:27:32] <Jacky^> I'm too ..
[21:27:40] <Jacky^> I just tried fo fun
[21:28:23] <Jacky^> a good solution should be vmware, but .. commercial
[21:29:21] <Jacky^> latest vmware + vmtools work fine
[21:30:03] <Jacky^> Yuga: which apps should you run ?
[21:31:34] <Yuga> i dont have a clue... trying to find out what the emc chap's run
[21:33:17] <Jacky^> ah, ok
[21:35:25] <Yuga> wanna download a dbi install and put it on one of my machine's just 2 c how the program work's and all
[21:35:40] <Yuga> i am very new at this and trying to do asmuch research as possible
[21:36:04] <Yuga> Jacky^ / cradek u's have a cnc machine?
[21:36:08] <Jacky^> right way, i agree with you
[21:36:16] <cradek> Yuga: http://timeguy.com/
[21:36:28] <Jacky^> Yuga: the mine it's a very expensive machine
[21:36:38] <Jacky^> professional I mean..
[21:36:48] <Yuga> cnc router?
[21:36:53] <Jacky^> yeah
[21:37:14] <Yuga> hehe... cnc drill press?
[21:37:30] <Jacky^> take a look: http://www.roboitalia.com/modules.php?name=coppermine&file=displayimage&album=random&cat=&pos=-676
[21:37:34] <Jacky^> :D
[21:37:57] <Yuga> * Yuga has this problem... i hate doing anything small
[21:37:57] <Jacky^> total price $ 60
[21:38:21] <Yuga> and the shit thing is that i dont realy know anything :)
[21:38:39] <cradek> Jacky^: what does the table slide on?
[21:38:44] <Jacky^> but i changed the dremel in the pic with a 600 w router
[21:39:18] <Jacky^> cradek: the X table
[21:39:32] <cradek> Jacky^: yes are they drawer slides?
[21:39:45] <Jacky^> yes,
[21:39:46] <Yuga> how much play does a pinion/rack system have?
[21:40:02] <Jacky^> I don't know how this is called in english :\
[21:41:05] <cradek> I have to go; goodnight everyone
[21:41:14] <Jacky^> night cradek
[21:41:24] <Yuga> night
[21:44:14] <Jacky^> Yuga: i started 3 mounth ago
[21:44:27] <Jacky^> but i made from myself anything
[21:44:43] <Jacky^> inexpensive cnc, hw controller, etc..
[21:44:51] <Jacky^> very funny ;)
[21:44:57] <Yuga> well i wanna build a big machine
[21:45:02] <Jacky^> I learned many things
[21:45:04] <Yuga> no point in doing it twice :)
[21:45:10] <Yuga> what program's u use?
[21:45:30] <Jacky^> BDI 4.20 linux
[21:45:43] <Jacky^> the gui is not so important..
[21:45:59] <Jacky^> all are working fine for me
[21:46:02] <Yuga> yes.. but gui's are always nice :)
[21:46:12] <Jacky^> yeah..
[21:46:21] <Yuga> how easy was it to get it all working off bdi?
[21:46:39] <Jacky^> very easy
[21:47:02] <Jacky^> but I'm a linux user since 2001..
[21:47:16] <Yuga> well i am new :)
[21:47:23] <Jacky^> I don't know how much experience you have with linux
[21:47:33] <Yuga> have used it... but never realy been that successfull
[21:47:58] <Jacky^> strange..
[21:48:06] <newb1e> sorry
[21:48:38] <Jacky^> It for me worked at the first time e without install , directly from live cd
[21:49:19] <Jacky^> You just need to learn how to setup correctly the ini file, nothing more..
[21:49:37] <Yuga> and how difficult was it to get it to runn with your cnc machine?
[21:50:49] <Jacky^> before to get my machine working with gcode and file (with the right axes setting) i spent some week..
[21:51:07] <Jacky^> before I just manually move the axes
[21:51:19] <Jacky^> pushing a button :)
[21:52:19] <Yuga> cool... what steppers u using?
[21:52:30] <Jacky^> you can take the advantage of understand well english (I'm not)
[21:52:43] <Jacky^> read the handbook on the website
[21:52:51] <Jacky^> is very useful
[21:53:31] <Jacky^> http://www.micromed.it/Elettronica/stepper.htm
[21:53:43] <Jacky^> I bough 3 stepper for E. 30
[21:53:47] <Yuga> first need to download the bdi install... problem is that i dont think i have enough bandwidth left this month
[21:53:54] <Jacky^> 2 A
[21:54:07] <Jacky^> like this: http://www.micromed.it/Elettronica/images/C018.jpg
[21:54:31] <Yuga> and they cost u how much?
[21:54:51] <Jacky^> E. 10 anyone ($10)
[21:55:44] <Jacky^> it's a very nice price in this website
[21:56:21] <Yuga> yep... the problem is that i am looking for realy big steppers :)
[21:56:46] <Jacky^> if the stepper is big, then also the driver will big..
[21:57:06] <Yuga> yep... buying those gecko drives
[21:57:09] <Jacky^> I think gecko drivers should be fine
[21:57:12] <Jacky^> :)
[21:57:38] <Yuga> but the problem is to find a big stepper now
[21:57:44] <Jacky^> yeah..
[21:57:46] <Yuga> not that many big one's around
[21:58:02] <Jacky^> will be expensive too..
[21:58:18] <Yuga> ya... willing to pay for them thou
[21:58:23] <Yuga> just need to find the buggers
[21:58:32] <Jacky^> how much ampere should have the motor ?
[21:58:35] <Jacky^> you know ?
[21:59:03] <Yuga> not a clue
[21:59:08] <Yuga> just looking for some big one's
[21:59:17] <Jacky^> I suppose mor of 4 ..
[21:59:35] <Yuga> give me a sec... will find the one's i was looking at
[22:00:26] <Yuga> http://www.campbelldesigns.com/stepper-motors.php <--- the one at the very bottom
[22:00:36] <Yuga> was looking for a bigger one thou. that one's 6 amps
[22:01:17] <Jacky^> 6 ampere per phase
[22:01:44] <Jacky^> should be very strong :)
[22:01:59] <Yuga> yes... but i am trying to make one hell of a big cnc machine :)
[22:02:01] <Yuga> 3mx2m
[22:02:31] <Jacky^> yeah..
[22:02:59] <Yuga> so ya... i need big motor's
[22:03:07] <Jacky^> nice
[22:03:20] <Yuga> i should probibly go for servo's. it just seem's that i need alot bigger budget then
[22:03:43] <Jacky^> servo's should be better than stepper
[22:03:52] <Jacky^> I live in Italy and..
[22:04:01] <Jacky^> I don't know where you are
[22:04:11] <Yuga> yes... but i dont fully understand how servo's work. so it makes it alot harder
[22:04:14] <Yuga> i am from south africa
[22:04:21] <Jacky^> if in UK or US, there are meny peoples here
[22:04:29] <Jacky^> ah..
[22:04:37] <Jacky^> no idea
[22:04:43] <Yuga> south africa = little shit hole :)
[22:04:48] <Jacky^> where to buy from there..
[22:04:53] <Yuga> so ya... all the info i have is off the net
[22:05:01] <Jacky^> nice :)
[22:05:10] <Yuga> i am going to have to import them from the us or australia
[22:05:55] <Jacky^> I think also Japan could be a good option
[22:06:13] <Jacky^> or Taiwan maybe..
[22:06:15] <Yuga> ya... but difficult to find japanees sites
[22:06:19] <Jacky^> yeah
[22:06:49] <Yuga> know of anny?
[22:06:51] <Yuga> any?
[22:07:20] <Jacky^> no.. really
[22:08:47] <Jacky^> but I think the price's there would be much better :)
[22:09:04] <Yuga> they would be... but to find them :P
[22:09:09] <Jacky^> hehe
[22:22:52] <robin_sz> meep?
[22:23:06] <A-L-P-H-A> some one kill me.
[22:23:37] <Jymmm> A-L-P-H-A : Can't, probably on the no-fly list!
[22:24:03] <Jymmm> A-L-P-H-A Hey! tha'ts what you can do.... goto the airport and yell 'gihad' and bob
[22:24:22] <robin_sz> looks like I have to visit the US in a couple of weeks
[22:24:22] <A-L-P-H-A> bob?
[22:24:25] <A-L-P-H-A> bomb?
[22:24:27] <Jymmm> I'm sure someone will kill you
[22:24:48] <Jymmm> robin_sz Good to know, I'll contact TSA on your behalf =)
[22:25:32] <robin_sz> Tennessee Savings Association?
[22:26:03] <Jymmm> robin_sz: No, the dumbass mother fuckers at the airport that think EVERYONE is a terrorist... even the 6mo old babies
[22:27:02] <Jymmm> http://www.tsa.gov/public/
[22:29:11] <Jymmm> A-L-P-H-A why, what happened?
[22:29:17] <Jymmm> robin_sz : where to ?
[22:33:45] <robin_sz> ummm, new york
[22:33:51] <robin_sz> is it cold there ?
[22:33:55] <Jymmm> Ah, never been there.
[22:34:02] <robin_sz> I thnk its in the north
[22:34:25] <Jymmm> robin_sz http://www.google.com/search?q=weather+new+york+new+york&sourceid=mozilla&start=0&start=0&ie=utf-8&oe=utf-8
[22:34:35] <robin_sz> in the films, it always has snow piled up in the streets
[22:34:39] <Jymmm> 90F
[22:35:02] <robin_sz> in centigrade?
[22:35:05] <Jymmm> yeah, in the winter time.
[22:35:24] <Jymmm> 32.2c
[22:35:30] <robin_sz> * robin_sz boggles at the TSA site
[22:35:43] <robin_sz> you know, the terrorists have already won
[22:36:00] <Jymmm> gawd damn fucking patriot act! should have NEVER happened (the end does not justify the means)
[22:36:47] <robin_sz> but its the Patriot act ...
[22:36:53] <Jymmm> That is one thing I could go to jail for.
[22:37:05] <robin_sz> if you dont like it you must be un-patriotic ...
[22:37:24] <Jymmm> not a joking matter.
[22:37:40] <robin_sz> whenever the wankers over here want to get through someting, they call it like "the criminal justice bill"
[22:38:02] <Jymmm> but they didn't get chased across town for photography either.
[22:39:36] <robin_sz> whatever
[22:39:50] <robin_sz> you'll notice that in the UK we are just getting on as normal
[22:40:25] <robin_sz> although I did here there were some more bombs today.
[22:40:31] <robin_sz> I think
[22:40:53] <Jymmm> I'm just venting. If I really got into the conversation I'd probably need a self induced defibulator.
[22:42:06] <Jymmm> What you think.... 0-60VDC @ 0-13A linear PS for $150 ?
[22:42:33] <Jymmm> USD
[22:42:52] <robin_sz> verty cheap
[22:43:00] <robin_sz> what you want that for?
[22:43:16] <robin_sz> lab use?
[22:45:15] <robin_sz> probably a very poor choice for running a machine from
[22:54:54] <Jymmm> well, running a machinw was my first choice (lab being 2nd).
[22:55:15] <robin_sz> well, not a good choice really
[22:55:42] <Jymmm> becasue it's regulated?
[22:55:52] <robin_sz> partly
[22:56:21] <robin_sz> whats wrong with a transformers and a capacitor huh?
[22:56:59] <Jymmm> finding a XMFR is difficult... not a lot of electrical surplus in the area.
[22:57:15] <Jymmm> anymore
[22:57:41] <robin_sz> how many amps do you need
[22:57:43] <robin_sz> ?
[22:57:46] <Jymmm> the other thing I figured is it being variable I can adjust as needed down the orad.
[22:58:16] <Jymmm> I'm thinking abotu getting some geckos
[22:58:24] <robin_sz> how many amps do you need?
[22:58:41] <Jymmm> at least 4
[22:59:29] <robin_sz> and how many volts?
[22:59:35] <Jymmm> no clue
[22:59:40] <robin_sz> well, whats the rating of your motors?
[22:59:52] <Jymmm> http://www.xylotex.com/StepperMotor.htm
[23:00:22] <Jymmm> 3.164
[23:00:40] <Jymmm> * 20 = 63.28
[23:00:48] <robin_sz> so a 60V supply is about right
[23:00:58] <robin_sz> 60V @ 4A = 250Va
[23:01:04] <robin_sz> VA even
[23:01:26] <Jymmm> 48V xfmr * 1.4 == 67.2V
[23:01:40] <robin_sz> try a 35V
[23:02:03] <robin_sz> gives about 57V
[23:02:22] <Jymmm> see, evening finding 12,24,48V @4A is difficult
[23:02:31] <robin_sz> is it bollocks
[23:02:35] <Jymmm> well 12V is easy
[23:02:41] <Jymmm> bollocks?
[23:02:41] <robin_sz> digikey, mousser ...
[23:02:49] <robin_sz> "rubbish"
[23:02:54] <Jymmm> oh, just expensive
[23:03:36] <robin_sz> shrug
[23:04:07] <Jymmm> If I spend say $70 on a xfmr + caps + misc hardware I'm almost at the $150 range of this PS which is ready to go and I can adj the voltage lower if needed
[23:04:14] <Jymmm> that was my thinking.
[23:04:28] <Jymmm> by $70 I mean with tax ans shipping
[23:05:33] <Jymmm> If I could find a couple XFMR's locally for $20/ea and wire them series/parallel, that's another story
[23:06:09] <robin_sz> shrug ..
[23:06:25] <robin_sz> mine cost about 20 GBP (35USD) from Farnell
[23:06:38] <robin_sz> but the last few I wound myself :)
[23:07:05] <Jymmm> Now... If I had the time and a clue in winding microwave xfrm's.... now were talking!!!
[23:07:44] <robin_sz> microwave txfrms? the high voltage single ended tings?
[23:08:20] <robin_sz> they don't even have them in the spares catalogues anymore
[23:08:22] <Jymmm> Yep, taking out the secondary adn wind my own (someone on here already did that)
[23:08:35] <robin_sz> oh, weird
[23:08:52] <Jymmm> I think Phydbleep is the one the rewind them
[23:09:14] <robin_sz> well, I would just buy a toroid for about 20 dollars and stop worrying
[23:09:29] <Jymmm> where from?
[23:09:42] <robin_sz> well, I got mine from farnell
[23:12:51] <Jymmm> heh.... iso xfmr and a variac!
[23:13:21] <robin_sz> you ordered that?
[23:13:30] <Jymmm> nah
[23:13:50] <Jymmm> can't find the isolation xfmr big enough
[23:14:12] <robin_sz> yeah right
[23:14:15] <Jymmm> huh? Autotransformers provide the most cost effective solution for voltage conversion when electrical isolation is not required
[23:14:24] <robin_sz> correct
[23:14:28] <Jymmm> why?
[23:14:56] <robin_sz> well, isolation txfmrs are generally either 1500VA or 3300VA
[23:15:04] <robin_sz> either would be big enough
[23:15:20] <Jymmm> no, I mean why doesn't a autotransformer provide isolation?
[23:15:31] <robin_sz> because it only has one winding
[23:15:39] <robin_sz> not two
[23:15:47] <Jymmm> OH! no secondary
[23:15:52] <robin_sz> correct
[23:15:58] <robin_sz> so cant be used with geckos
[23:16:00] <Jymmm> I never knew that.
[23:16:28] <robin_sz> well, err, thats the difference between a normal txfmr and an auto transformer
[23:16:55] <Jymmm> Yeah, I understand now. I just never realize what a "AUTOtransformer" really was.
[23:17:01] <robin_sz> right
[23:17:12] <robin_sz> auto as in self
[23:17:16] <robin_sz> not automatic
[23:18:29] <Jymmm> ah ha!
[23:18:53] <Jymmm> I talked to a XMFR mfg up norht a long time ago, just found them again!
[23:19:02] <Jymmm> very nice folks
[23:19:13] <Jymmm> will make a xfmr to your specs
[23:37:50] <robin_sz> I must admit, I'm confused
[23:43:04] <roel01> hi
[23:43:46] <Jacky^> hi
[23:44:30] <roel01> :) lots of new faces around here !

[23:55:01] <Jacky^> I mean working around emc ?
[23:55:17] <roel01> nope i triet for a while but can't get it done
[23:55:26] <Jacky^> :)
[23:55:55] <Jacky^> I'm not too
[23:56:01] <Jacky^> too few time :\
[23:56:16] <Jacky^> too much to learn

[23:56:32] <Jacky^> plasma ? cool
[23:57:16] <roel01> yeah making my own sprockets
[23:57:32] <Jacky^> nice
[23:58:38] <Jacky^> the mine is a toy-machine.. lol
[23:58:46] <Jacky^> just for fun
