[00:01:27] <jt-plasma> LOL
[00:01:36] <jt-plasma> come on Jymmm
[00:01:50] <jt-plasma> if it is good music I'll listen to it
[00:02:01] <Jymmm> jt-plasma: Hey, we all know you're a polka kinda guy!
[00:02:25] <jt-plasma> now polka your talking about the Big Jim Polka show
[00:03:20] <jt-plasma> or what ever it was called
[00:03:20] <Jymmm> *I* wouldn't know
[00:03:20] <jt-plasma> LOL
[00:03:21] <jt-plasma> I'm a veteran cosmic rocker if you want to know
[00:03:21] <Jymmm> jt-plasma: I never hear the words "Pink floyd" come out of your mouth
[00:04:01] <jt-plasma> I had a I (heart picture) Pink Floyd bumper sticker on my 81 Chevy Pickup
[00:04:24] <jt-plasma> My now wife thought I was a cowboy till she saw that one day
[00:04:41] <Jymmm> so it came with the truck when you bought it, doens't mean jack!
[00:04:54] <jt-plasma> BS, I put it there
[00:05:02] <Jymmm> LOL
[00:05:13] <jt-plasma> Moody Blues and Pink Floyd are my heros
[00:05:45] <Jymmm> jt-plasma: Onlty because you couldn't find a "I [heart] Lawernce Welk" sticker - and for good reason too!
[00:05:52] <jt-plasma> throw in some Kate Bush and Leon Redbone and we have a party
[00:06:04] <jt-plasma> or Jim Stafford
[00:06:22] <Jymmm> BACK THE SHIT UP.....
[00:06:38] <Jymmm> You can't Put Kate Bush and Pink Floys in the same conversation
[00:06:53] <jt-plasma> oh and don't forget Dr. Demento
[00:07:13] <jt-plasma> s/Floys/Floyd
[00:07:26] <Jymmm> Learn to speak typo!
[00:08:01] <Jymmm> jt-plasma: Floyd can't get anywhere near as high as Kate Bush voice
[00:08:20] <jt-plasma> and don't let Kraftwerk escape your listening pleasure
[00:08:35] <jt-plasma> I agree Mr. Pink doesn
[00:08:44] <jt-plasma> t have the range of Kate
[00:08:53] <Jymmm> jt-plasma: Oh gawd.... Kraftwerk, haven't heard that name in decades
[00:09:04] <jt-plasma> but don't leave Mr. Loaf
[00:09:09] <jt-plasma> out
[00:09:16] <Jymmm> jt-plasma: You do? Who kicked you in the nuts over and over again?
[00:09:43] <jt-plasma> Now it is the Shangri-Las playing
[00:10:04] <jt-plasma> Leader of the Pack
[00:10:47] <Jymmm> jt-plasma: Don't make me open a can of whop ass and slap some Glenn Miller on the table
[00:11:04] <jt-plasma> ok Dr. Hook
[00:11:15] <Valen> I like the coors, taylor swift, avril, gwen stefani,
[00:11:19] <jt-plasma> Cover of the Rolling Stone
[00:12:09] <Valen> oh yeah and little birdy, rouge traders
[00:12:10] <jt-plasma> Valen: I've not had the pleasure of listening to them
[00:12:33] <Valen> jt-plasma, a fringe benifit is they are all hawt chicks
[00:13:14] <jt-plasma> I'm still searching for "From the Indies to the Andes in my Undies" but can't find it
[00:14:14] <jt-plasma> oh boy some Jelly Roll Morton is playing now
[00:15:37] <jt-plasma> nice the Pickup Truck Song by Jerry Jeff Walker
[00:16:09] <jt-plasma> http://www.youtube.com/watch?v=RWK8GgWD4uA
[00:18:42] <jt-plasma> * jt-plasma wonders why you tube won't play over the speakers on 8.04
[00:19:28] <Jymmm> From Kraftwerk to Country.... You had (have?) a mullet at one time, didn't you john?
[00:19:47] <jt-plasma> no, but I use to cast net them
[00:19:54] <Jymmm> rotf
[00:19:55] <jt-plasma> in Mississippi
[00:20:07] <Jymmm> liar, you had one!
[00:20:09] <jt-plasma> home made cast nets
[00:20:21] <jt-plasma> I had an afro once
[00:20:30] <jt-plasma> or a perm what ever you call it
[00:20:35] <Jymmm> eh, that's ok.
[00:20:43] <jt-plasma> it was worth it :)
[00:21:00] <Jymmm> did you marry her?
[00:21:04] <jt-plasma> nope
[00:21:10] <Jymmm> =)
[00:21:11] <jt-plasma> LOL
[00:21:55] <Jymmm> You actually have Krafwerk on cd/mp3?!
[00:22:37] <jt-plasma> an album!
[00:22:47] <Jymmm> like 33?
[00:23:15] <jt-plasma> yep
[00:23:21] <Jymmm> They have usb turntables and cassette desk now (just fyi)
[00:23:30] <Jymmm> deks
[00:23:33] <Jymmm> decks
[00:23:39] <jt-plasma> my turntable still works :)
[00:24:06] <Jymmm> I meant to convert to mp3 - you sick puppy!
[00:24:19] <jt-plasma> along with my Polk audio Model 10 speakers
[00:24:51] <Jymmm> Heh, I saw a pair of Bose 901's at the goodwill the other day
[00:25:22] <jt-plasma> Damm, that is sad for sure
[00:25:44] <Jymmm> Yeah, I have no amp's or it might have been worth checking them out.
[00:26:15] <jt-plasma> oh now it is Lynyrd Skynyrd playing Tuesdays Gone
[00:27:00] <jt-plasma> or Bob Dylan playing the Hurricane
[00:27:15] <jt-plasma> * jt-plasma goes in to check out dinner
[00:27:29] <jt-plasma> ttul Jymmm
[00:27:51] <Jymmm> jt-plasma: Hasta! =)
[00:28:21] <Valen> hmmm my isp is rolling out native ipv6
[00:29:33] <Valen> only problem is the unmetered content I ususally use would no longer be unmetered
[00:29:40] <Valen> which is somewhat sucky
[00:57:42] <pfred1> Valen what do they meter?
[00:58:31] <pfred1> I rip MP3s off my turntable
[01:14:28] <Valen> traffic
[01:14:30] <Valen> data
[01:14:43] <Valen> but they host ubuntu repos etc that are unmetered
[01:21:28] <pfred1> Valen what is it wireless like on a phone?
[01:32:36] <Valen> no its adsl
[01:34:28] <pfred1> Valen isn't dsl like bandwidth limited anyways?
[01:34:35] <pfred1> I remember mine was
[01:35:04] <Valen> you get a quantity of gb included and if you go over that you get rate limited to dialup or so
[01:35:38] <pfred1> Valen yeah but its pretty high right?
[01:35:53] <pfred1> I mean lets be reasonable
[01:36:23] <Valen> 10gb on my plan
[01:36:55] <Valen> but mine is an expensive service
[01:37:35] <Valen> its $80 a month incl phone line rental
[01:37:54] <Valen> for $50 you can get 50Gb ex phone on a residential plan
[01:37:56] <pfred1> yeah 10 gb is a lot
[01:38:09] <Valen> not really
[01:38:22] <Valen> download 2 dvd iso's of linux and you have used it all
[01:38:51] <pfred1> one thing debian had was the nice network install
[01:39:06] <pfred1> download 2 floppy images then net install the rest
[01:39:15] <pfred1> heck I'd irc while it was doing it
[01:39:52] <pfred1> lots of image crap you never use
[01:43:04] <Valen> not so good if your installing lots of times
[01:43:33] <pfred1> Valen I suppose not but this system as an example I installed in oh 2003
[01:44:30] <Valen> bbl
[01:44:38] <pfred1> SuSE Linux 8.2 (i586)
[01:45:06] <pfred1> -rw-r--r-- 1 root root 36 Mar 27 2003 SuSE-release
[01:45:38] <pfred1> maybe I should upgrade one of these days ...
[02:25:19] <LawrenceG> jt-plasma, - John, you need to sudo apt-get install libflashsupport to get flash sound back.. a recent update broke the flash plugin for mozilla
[03:16:57] <Jymmm> LawrenceG: thats good to know
[03:24:22] <LawrenceG> Jymmm, yea... I finally went googling and fixed my box thismorning
[03:24:36] <Jymmm> Ah, ok.
[03:24:54] <Jymmm> LawrenceG: I think I'm going to me one of these...
http://www.arrowantennas.com/j-pole.html
[03:25:17] <LawrenceG> I think there were some bad flaws in the flash plugin.....
[03:25:29] <Jymmm> there alwasy is.
[03:26:19] <LawrenceG> those are nice solid antennas.... you can build one if you have some spare Al. I think I have dimensions around here... let me look
[03:26:45] <Jymmm> LawrenceG: Not for the price he's selling them for.
[03:28:50] <LawrenceG> http://imagebin.ca/view/IoxenR.html
[03:29:46] <Jymmm> cool
[03:30:03] <Jymmm> bbl, thanks!
[03:30:14] <LawrenceG> cheers
[05:15:55] <funkydruid> hello
[05:38:22] <funkydruid> can anyone tell me what CAD software people are using in conjunction with EMC2? I use Rhino3D and I am interested in the Sherline range of CNC milling machines, with the the 4th Axis. I am planning to machine wax for "Lost wax casting" of jewelry.
[05:57:51] <Jymmm> funkydruid: Are you looking for something cheap or ???
[05:59:34] <MrSunshine> i started using heekscad/cnc, great software tho a bit unstable :/
[05:59:40] <Jymmm> funkydruid: It's probably not without it's own issues, so be sure to fully test drive it before buying, but it's CAD AND CAM all in one...
http://www.artcamjewelsmith.com/
[05:59:48] <MrSunshine> ahh 4 axis i dunno if it can do :)
[06:56:24] <funkydruid> heekscad/cnc?
[06:56:34] <funkydruid> yeah - im looking for something cheap
[07:03:12] <funkydruid> artCAM looks like a pretty nice tool kit
[07:03:51] <MrSunshine> funkydruid, look it up on google
[07:03:54] <funkydruid> currently I use kerkythea to render my drawings. and I have access to a Roland MDX 20 mill, but I'd like my own within a budget :)
[07:54:50] <Jymmm> funkydruid: Heh, ArtCAM is about $10,000 USD
[07:58:51] <alex_joni> you can also check out Alibre CAD/CAM
[07:59:08] <alex_joni> they have some freeish version, full parametric CAD + 3 axis CAM is < 2k$
[08:01:02] <Jymmm> not even 4 axis?
[08:01:07] <Jymmm> for the cam I mean
[08:01:31] <alex_joni> they have up to 5 axis CAM
[08:02:04] <alex_joni> http://www.alibre.com/store/c-10-alibre-cam-software.aspx
[08:03:09] <Jymmm> th axis = $2K usd
[08:03:11] <Jymmm> 4th
[08:03:40] <Jymmm> alex_joni: how is it compared to SW?
[08:04:04] <alex_joni> I like it better
[08:04:10] <alex_joni> and it's way cheaper
[08:04:31] <Jymmm> can you call out dimensions like 12+3.5 ?
[08:04:33] <alex_joni> haven't used SW a lot though.. but when I did, I found some things easier/faster in alibre
[08:04:36] <alex_joni> sure
[08:04:41] <Jymmm> cool
[08:05:25] <alex_joni> Jymmm:
http://juve.ro/blog/projects/01257499815
[08:08:58] <Jymmm> cool
[08:19:29] <alex_joni> Jymmm: model in alibre
[08:21:23] <ds3> alex_joni: you use alibre?
[08:22:48] <alex_joni> yeah
[08:33:46] <ds3> alex_joni: how do you like it?
[09:03:10] <alex_joni> ds3: enough to buy it :P
[09:08:35] <alex_joni> until a comparable OSS comes along

[18:49:48] <MattyMatt> I'm tempted to put my Z in the pillars
[18:52:00] <MattyMatt> it seems a good compromise of stiffness when low, and highness when high
[21:01:50] <yoyoek1> hi
[21:14:19] <awallin> "highness when high" :)
[21:15:34] <pfred1> hello.
[21:16:35] <pfred1> is there anyone here I can ask a stepper motor driver speed question?
[21:16:42] <archivist> ask
[21:16:49] <pfred1> ok
[21:17:12] <pfred1> I'm wondering what is a good target clock speed I should be able to run my motors at
[21:17:42] <pfred1> clock step
[21:18:01] <archivist> depends on motor and steps per rev and max speed of your particular motors
[21:18:16] <archivist> and if using micro steps
[21:18:43] <archivist> and mass being moved
[21:19:24] <pfred1> so far the faster I run my motors the less torque they deliver
[21:19:36] <archivist> thats normal
[21:19:53] <pfred1> yes what I want to know is what is a fair happy balance speed
[21:20:12] <pfred1> like I can run my motor with a 35.5 uS clock
[21:20:26] <pfred1> but at that speed you breathe on it and it'll stall
[21:20:32] <archivist> each setup needs testing, and base your maximum to allow for load variations
[21:20:59] <pfred1> but if I run it at say .6 ms clock it is very powerful
[21:21:06] <archivist> you need spare torque for cutting load etc
[21:21:43] <pfred1> well I don't think the motor will put out any more torque than at the .6 ms clock
[21:22:49] <pfred1> around there is where I get very reliable reversing starting etc
[21:22:50] <celeron55> if that's fast enough, try setting it at that then and see if it'll work for you
[21:23:23] <pfred1> celeron55 yeah before I build three motor drivers i guess I was hoping for some reassurance?
[21:23:41] <pfred1> celeron55 I'd hate to be out all the time and money you know?
[21:24:37] <archivist> clock speed is adjustable, we in here will be assuming you are using EMC to get that
[21:24:55] <pfred1> archivist nope right now just a 555 timer
[21:25:11] <pfred1> archivist adjustable with a potentimeter
[21:25:24] <skunkworks_> are you ramping up?
[21:25:28] <archivist> in the final build?
[21:25:48] <pfred1> * pfred1 is confused
[21:25:57] <pfred1> explain ramping up
[21:26:05] <archivist> steppers need to accelerate to max speed
[21:26:14] <pfred1> archivist yes I've noticed
[21:26:18] <celeron55> if you're going to use emc, you don't need to worry about reversing and starting, because it will accelerate them smoothly
[21:26:28] <pfred1> you can't start out at 2,000 RPM
[21:26:29] <archivist> this is all controlled by software
[21:27:04] <pfred1> celeron55 hmm so I've been beating my head with these motor drivers for nothing?
[21:27:05] <archivist> 2-3k rpm is about max for a stepper
[21:27:26] <archivist> the output stage you still need
[21:27:27] <pfred1> archivist yeah it sounds like it is about to fly apart there
[21:27:44] <archivist> what driver chip are you using
[21:27:59] <pfred1> SLA7026 with half stepping logic sequencer
[21:28:21] <archivist> clock and dir can be driven from emc
[21:28:33] <pfred1> archivist yeah
[21:28:51] <pfred1> archivist I'm trying to put something together that emc can drive
[21:29:08] <archivist> remove the 555 and you have it
[21:29:11] <pfred1> just was wondering if I was there yet or not
[21:29:24] <archivist> seems you are
[21:29:29] <pfred1> well I've built a few different motor drivers
[21:29:38] <pfred1> each one a bit better than the last
[21:30:10] <pfred1> seems there are a lot of differentdesigns
[21:30:45] <pfred1> * pfred1 is having commitment issues ...
[21:30:51] <celeron55> probably all of them are good enough
[21:30:54] <celeron55> for basic use
[21:31:01] <archivist> bipolar is generally better than unipolar
[21:31:12] <pfred1> yeah these are just unipolar
[21:31:36] <archivist> should be ok
[21:31:51] <pfred1> stuff is strong though I should duck tape it to my mill and see if it'll drive it
[21:32:17] <pfred1> initially I didn't think the motors i have coulddo it but I'm not so sure anymore
[21:32:36] <archivist> you can then use stepconf to test at various speeds
[21:32:39] <pfred1> they only 124 oz/in but
[21:33:09] <pfred1> I'm wondering if people using much stronger motors just have crappy drivers
[21:33:39] <pfred1> or crappy power supplies
[21:33:51] <celeron55> 124oz/in isn't that bad
[21:34:01] <pfred1> celeron55 I'm finding that out
[21:34:17] <pfred1> they can be
[21:34:29] <pfred1> if you screw something up with the build
[21:34:34] <celeron55> people generally recommend about 1Nm and 124oz/in is 0.86Nm
[21:35:01] <pfred1> but this last motor driver i made is like a freight train
[21:35:32] <skunkworks_> http://www.youtube.com/watch?v=fl3om2mG5gA
[21:35:51] <pfred1> * pfred1 has no Flash :(
[21:36:22] <celeron55> why not install it
[21:36:37] <pfred1> celeron55 they don't support my version of glibc
[21:37:07] <pfred1> celeron55 or i could say I did but it doesn't do anything
[21:37:33] <celeron55> so what OS are you using? :P
[21:37:35] <pfred1> which is kind of nice for all the ads
[21:37:46] <pfred1> celeron55 old version of linux
[21:38:00] <pfred1> from 2003
[21:38:09] <celeron55> why not get a more recent one
[21:38:18] <pfred1> celeron55 7 years of data
[21:38:33] <pfred1> thats a lotta work
[21:38:47] <pfred1> someday I'll just get a whole new machine
[21:39:01] <skunkworks_> that is an awesome video
[21:39:07] <celeron55> you can always make a backup and save the data otherwise?... well, on the other hand, "if it works, don't fix it" :P
[21:39:38] <pfred1> celeron55 yeah if somehow I could backup 500 gb
[21:39:51] <pfred1> tough to fit that on a floppy
[21:40:14] <pfred1> but anywho
[21:40:32] <pfred1> yeah so emc will ramp the motor for me?
[21:41:23] <pfred1> thats great! I'll make hard copies of these boards pronto and move on with all of this
[21:42:05] <pfred1> I guess down the road i can always get new motors and make new drivers for them
[21:42:30] <pfred1> I got one motor an old astrosyn thats a goliath
[21:42:42] <pfred1> something like 4 amps a phase
[21:43:42] <pfred1> haven't made a driver for it yet
[21:46:27] <celeron55> you don't actually need flash for watching youtube videos if you use for example
http://bitbucket.org/rg3/youtube-dl/wiki/Home
[21:46:51] <pfred1> celeron55 yeah? because i have like mplayer
[21:47:46] <archivist> skunkworks, that blender addon looks good
[21:48:00] <Jymmm> add-on?
[21:48:07] <celeron55> but i'm off to bed now ->
[21:48:17] <pfred1> archivist I think they named that software for how my head feels when I try to use it!
[21:48:47] <pfred1> once i got it to render a sphere
[21:48:55] <pfred1> that was about it :(
[21:49:31] <Jymmm> archivist: add-on?
[21:49:40] <archivist> Jymmm,
http://www.youtube.com/watch?v=fl3om2mG5gA
[21:49:40] <pfred1> and the scene was so dark you had to know it was there
[21:51:06] <skunkworks_> archivist_emc: doesn't it? I am impressed.
[21:52:14] <archivist> trying to find out more is hard though!
[21:52:32] <Jymmm> wth... it generates the gCode on the fly?
[21:52:50] <archivist> looks the sexy
[21:53:03] <skunkworks_> I think it is someone on here... I thought I remember someone mentioning it.
[21:53:30] <gweepprefect> can you make any of that stuff with those tools dimensionally accurate?
[21:54:03] <skunkworks_> I don't know blender - so I could not tell you.
[21:54:11] <Jymmm> Hmmm, seems to be only outlining the wireframe and not the 3D it represents.
[21:54:16] <pfred1> skunkworks_ you ain't the only one!
[21:56:54] <archivist> hmm no mention on the mailing lists
[21:58:05] <pfred1> whoot this stuff works!
[21:59:28] <skunkworks_> this?
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Blender2Gcode
[21:59:33] <Jymmm> It's tracing. Not really doing 3D
[22:00:26] <archivist> skunkworks, ah you found it
[22:01:49] <archivist> skunkworks, google fails to find some emc wiki pages
[22:02:32] <skunkworks_> bbl
[22:06:35] <Jymmm> archivist: Ok, so am I mistaken or is it only tracing atm?
[22:07:16] <Jymmm> I was trying to watch AXIS, and it looks like it plunges into the material
[22:07:32] <archivist> its a drop cutter algorithm just close up the lines for a better finish
[22:08:12] <pfred1> the video I'm watching looks like a robotic fat chick
[22:08:12] <archivist> very much like awallin was doing
[22:08:28] <Jymmm> I dont know what that means. I saw it drop the tool directly into a valley without considering a block of material to clear away.
[22:08:59] <pfred1> Jymmm I ran a mill like that once :)
[22:09:09] <archivist> later in the vid he clears by layer
[22:09:20] <pfred1> Jymmm you had to walk into it
[22:09:32] <gweepprefect> it's not much of a tutorial, it needs narration.
[22:10:11] <archivist> I have no sound here
[22:10:20] <Jymmm> It looks to me (as it stands now) it be breaking tools. Very cool start of course.
[22:10:31] <pfred1> archivist don't worry you not missing anything
[22:10:39] <gweepprefect> might work fine in foam :)
[22:11:00] <Jymmm> gweepprefect: Try it and let us know =)
[22:11:11] <gweepprefect> haha.. no thanks. you first, i insist!
[22:11:13] <archivist> its up to the user to set sensible increments to suit tooling
[22:11:54] <pfred1> real machines go through steel like foam
[22:12:22] <Jymmm> not when you slam it into a valley
[22:18:11] <pfred1> Google just seems so brain dead lately
[22:20:19] <Jymmm> It'll be cool to see Verions 1.0
[22:20:42] <pfred1> Jymmm lots of stuff never makes it there

[22:47:36] <awallin> look, some pretty polygons:

[22:48:40] <archivist> next cutter cutting :)
[22:52:45] <pfred1> are Youtube filenames some kind of a code?
[22:53:07] <archivist> unique id
[22:53:20] <pfred1> archivist just random?
[22:53:35] <awallin> archivist: sure, the drop-cutter paths should not be that hard... weekend maybe
[22:53:39] <archivist> probably not random
[22:54:14] <pfred1> man I'm stoked to get going here and move onto something else
[22:54:26] <pfred1> making stepper motor drivers sort of sucks
[22:54:39] <awallin> steppers suck. use servos.
[22:54:40] <archivist> I was lazy and bought mine
[22:54:49] <pfred1> they're cantankerious
[22:55:01] <jt-plasma> I was extra lazy and bought good ones :)
[22:55:06] <pfred1> archivist the thought crossed my mind more than once
[22:55:41] <pfred1> jt-plasma the ones I've prototyped seem pretty good to me so far
[22:55:50] <jt-plasma> cool
[22:56:07] <pfred1> jt-plasma I've made others not so good
[22:56:22] <jt-plasma> do they morph from micro steps to full steps as the speed increases?
[22:56:23] <pfred1> so I do have something to compare them to
[22:56:35] <pfred1> jt-plasma nope just do full steps
[22:56:42] <pfred1> well half
[22:56:53] <pfred1> 1-2 phase excitation
[22:57:49] <jt-plasma> thats pretty cool too
[22:57:55] <pfred1> jt-plasma I tried some other stepping schemes and half seems like a good compromise
[22:58:16] <pfred1> though there are some novel drivers out there
[22:58:21] <jt-plasma> * jt-plasma wanders back into the thc comp to find my error :)
[22:58:52] <pfred1> these are different

[23:00:58] <andypugh> Linear? How 1970s
[23:01:19] <pfred1> andypugh not how they use it
[23:01:42] <pfred1> andypugh linear current amps
[23:02:01] <andypugh> Maybe not, but I have rather shied away from unipolar solutions too. If there are coils in the motor I want to use all of them, all the time.
[23:02:08] <pfred1> which I've listened to stepper motors enough to come to the audio conclusion with them too
[23:02:52] <pfred1> andypugh you do realize that some motors are just unipolar right?
[23:03:46] <pfred1> andypugh and I think the not use half the windings is when you drive a unipolar motor bipolar
[23:04:08] <pfred1> I haven't done it but I have read about it
[23:04:10] <andypugh> I suppose 5-wire always will be. But it seems to me you get more performance out of a given package size running bipolar
[23:05:50] <pfred1> andypugh the drives are a nightmare one of these days I'll make one
[23:06:29] <pfred1> andypugh really preferring bipolar is so 80s now ;)
[23:07:11] <pfred1> andypugh there has been a lot of work with microstepping and sine drive
[23:07:13] <andypugh> ?
[23:07:51] <pfred1> andypugh modern designs are getting fair performance out of unipolar motors these days
[23:09:36] <yoyoek1> hi
[23:09:56] <pfred1> hi
[23:10:01] <andypugh> I guess you can run further from the thermal limits using half your coils as a heat-sink half the time, but you can only fit so much copper in a given frame size, so you might as well use it to the full.
[23:10:09] <yoyoek1> I need edvice from expirient persone
[23:10:47] <frallzor> http://camcraftsa.com/cnc-routing-textures.htm anyone have an idea on how to make these textures?
[23:11:17] <frallzor> Im thinking bumpmapping and something that can do something with it like ArtCAM
[23:11:17] <pfred1> frallzor they look like Gimp textures
[23:11:30] <yoyoek1> I'm wonderint about implement that kinde off 3d routing
http://www.youtube.com/watch?v=ByUfrz_8_NE&feature=channel
[23:11:43] <MrSunshine> there is tutorials on how to make continiuus pattern images for gimp
[23:12:02] <pfred1> MrSunshine could always hire some Pakistanis too I suppose
[23:12:17] <frallzor> well patterns is one thing but to make it work like that is another =)
[23:12:23] <pfred1> make the extures!
[23:12:38] <MrSunshine> frallzor, wrap a paper around a cylinder, and start painting ... then cut it down the side and voila .. a vertical continius texture =)
[23:13:02] <pfred1> MrSunshine cypher?
[23:13:07] <MrSunshine> huh ? :)
[23:13:18] <frallzor> allmost a good idea :P
[23:13:28] <frallzor> paint, scan, make vectors :P
[23:13:29] <MrSunshine> it would work ...
[23:13:41] <MrSunshine> frallzor, but still, there is tutorials on how to make stuff like that for gimp
[23:13:42] <pfred1> MrSunshine

[23:15:02] <pfred1> oddly I thought the Romans made it first and famous
[23:15:57] <micges> yoyoek1: are you from Poland?
[23:16:02] <yoyoek1> yes

[23:55:23] <toastydeath> eh
[23:55:27] <pfred1> de
[23:55:42] <toastydeath> thereabouts
[23:55:48] <pfred1> you in de?
[23:56:00] <toastydeath> in that general area, yes
[23:56:09] <pfred1> yeah?
[23:57:53] <pfred1> * pfred1 is in de
[23:58:10] <pfred1> the LSD part of it
[23:59:40] <andypugh> LSD? Pounds Shillings and Pence? Lysyrgic Acid Deethylamine?
