#emc | Logs for 2006-02-27

[00:10:54] <giacus> night
[00:58:17] <skunkworks> ubuntu has seen all the odd on-board network cards I have tried it with.
[00:58:41] <skunkworks> I was suprised
[01:43:22] <Rif> Rif is now known as RifRaf
[02:03:17] <CIA-8> 03cradek * 10emc2/VERSION: moving TESTING
[02:04:20] <CIA-8> 03cradek * 10emc2/VERSION: Done tagging
[02:04:56] <skunkworks> cradek - going to bed - nice work this weekend. talk to you this week.
[02:07:00] <Jymmm> skunkworks: have you tried any of the Zircom nic's?
[02:07:13] <skunkworks> no I have not.
[02:07:30] <Jymmm> skunkworks: Yeah, you get mix results, ever for their age.
[02:08:08] <Jymmm> skunkworks: I even have the famous dual pcmcia nic/modem one that everybody used, it was okey.
[02:08:20] <skunkworks> right - there are some odd ones onboard that have worked for me.
[02:09:02] <skunkworks> :) I just ran across my linksys pcmcia card that was 10baseT and 10base2
[02:09:10] <Jymmm> I had my laptop setup for the zircom, W98 didn't like it nor did nix. Tossed in my 3Com... worked like a charm.
[02:09:34] <Jymmm> I have some of those in a junk box, but 3com.
[02:09:37] <cradek> do you guys mean Xircom or is there a ripoff called zircom?
[02:09:43] <skunkworks> sure don't miss coax ;)
[02:09:49] <Jymmm> Xircom, mybad
[02:10:05] <cradek> ok, just checking, not making fun - you were both spelling it with a Z
[02:10:18] <skunkworks> I didn't spell it ;)
[02:10:20] <Jymmm> cradek well, we pronounced it right at least =)
[02:10:32] <cradek> skunkworks: Jymmm and tfmacz
[02:10:35] <skunkworks> ah
[02:10:44] <Jymmm> skunkworks quit being paranoid!
[02:10:55] <skunkworks> I have spelling issues
[02:10:59] <Jymmm> lol
[02:11:03] <Jymmm> s/issues//
[02:11:15] <Jymmm> wait, fucked up that perfectly good joke
[02:11:31] <skunkworks> Hi my name is sam - it has been 2 hours sense my last spelling mestake
[02:11:32] <Jymmm> must need more coffee
[02:11:36] <skunkworks> oops
[02:11:58] <Jymmm> fucking amazing... http://www.maxwellrender.com/gallery.htm
[02:13:23] <skunkworks> wow - some people have too much time on thier hands ;)
[02:13:58] <skunkworks> ok - going to bed - night all.
[02:14:13] <Jymmm> Not necessarily... if that sells the job, it's worht it
[02:16:16] <skunkworks> :) I am just Jealous
[02:16:54] <Jymmm> skunkworks: =), we all are, we all are. Especially since you could send that to a cnc.
[02:17:41] <skunkworks> some day I want to be remotely able to do something like that. -- and send it to a machine.
[02:18:04] <skunkworks> time to play with solidworks or something similar.
[02:18:41] <Jymmm> skunkworks: SW is like 2D to 3D, but it seems if you start with 3D directly the 2D is childs play.
[02:19:13] <skunkworks> I have 2d down.
[02:19:27] <skunkworks> that is probably my problem than. ;)
[02:35:49] <cradek> new emc2, emc2-dev, emc2-axis packages in the ubuntu repository
[02:36:32] <rayh> wo ho! That will make for an interesting morning of testing.
[02:38:02] <cradek> there are a lot of little fixes... I hadn't noticed how many until I listed them
[02:38:21] <cradek> and be sure to check out the nifty new emc man page!
[02:38:33] <SWPadnos> 1.2a2-0.5?
[02:38:44] <LawrenceG> cradek: will down load now....
[02:38:50] <cradek> SWPadnos: yep
[02:38:56] <cradek> SWPadnos: and emc TESTING-2006-02-26
[02:39:44] <SWPadnos> I did 'apt-get install emc2-axis' - is there a better way?
[02:40:00] <cradek> SWPadnos: apt-get update; apt-get upgrade
[02:40:10] <cradek> SWPadnos: it will get the new versions of any packages you already have installed
[02:40:19] <SWPadnos> right - I didn't want to do that
[02:40:29] <SWPadnos> had trouble on the BDI, but I can see what happens here
[02:40:45] <cradek> SWPadnos: it always asks you for confirmation
[02:41:01] <cradek> SWPadnos: also there is the gui update-manager, system/administration/update-manager
[02:41:14] <cradek> SWPadnos: it will let you see the changelogs for the new packages BEFORE you commit to installing them
[02:41:49] <SWPadnos> well, I'll be brave and download the 131M of updates ;)
[02:41:49] <cradek> SWPadnos: and if you have trouble with a new package, you can always just downgrade it.
[02:42:03] <cradek> SWPadnos: wow, you must not have updated for a while.
[02:42:10] <SWPadnos> never, actually
[02:42:20] <SWPadnos> it's a new install of kubuntu 5.10
[02:42:30] <cradek> SWPadnos: I keep mine updated, and it has worked perfectly
[02:42:35] <cradek> ahh
[02:42:53] <SWPadnos> well, we'll see what happens in a few minutes
[02:43:01] <cradek> be sure to reboot after the kernel updates, other than that it's pretty foolproof
[02:43:38] <SWPadnos> I may be a better fool though - you never know
[02:45:21] <cradek> SWPadnos: I almost hate to ask, but did you have emc or system problems after upgrade on bdi?
[02:45:40] <SWPadnos> system - mostly kdm, I think
[02:45:48] <SWPadnos> aqt least, that's what I remembered of it
[02:45:59] <cradek> ok
[02:46:04] <SWPadnos> I think there were problems with the BDI repositories as well
[02:46:43] <cradek> I never used bdi seriously so I don't know what was in the repositories - but if he tried to keep up to date with all the debian changes, it seems like it would be easy to not get it 100% right
[02:47:39] <cradek> for us, system updates come straight from the ubuntu team, after going through their usual testing process
[02:47:49] <SWPadnos> I think it was more like issues getting updates or package lists
[02:48:10] <cradek> I'm trying to be reassuring - is it working? :-)
[02:48:26] <SWPadnos> cool - this version of apt does 3 transfers at a time
[02:49:14] <SWPadnos> I hadn't seen that on the command line before
[02:50:09] <cradek> this version of AXIS has some very nice i18n changes
[02:50:42] <SWPadnos> is there a polish translation?
[02:50:53] <SWPadnos> Polish, that is
[02:51:23] <cradek> no, we have en de hu it ro pt_BR
[02:51:36] <jepler> http://axis.unpy.net/translations
[02:51:36] <cradek> can you do a translation?
[02:51:49] <SWPadnos> no, but I may be able to get a .po translation from a friend
[02:51:55] <SWPadnos> .pl
[02:51:57] <jepler> we'd like that
[02:52:01] <cradek> very much
[02:52:09] <cradek> jepler: your change to the continuous box looks great
[02:52:11] <SWPadnos> I'll ask
[02:52:33] <jepler> cradek: good
[02:52:46] <cradek> was it de that didn't fit?
[02:52:55] <jepler> cradek: yes, I think so
[02:53:10] <cradek> all the languages look much better on this version
[02:53:20] <jepler> then we should make new screenshots for that page
[02:53:23] <cradek> even de
[02:53:26] <cradek> yes definitely
[02:53:34] <jepler> especially since so many of them have the "only jeff's machine" bug in the disabled toolbar buttons
[02:53:41] <cradek> haha
[02:53:47] <cradek> want me to take some shots?
[02:53:54] <cradek> I've got it running now
[02:53:57] <jepler> sure
[02:54:00] <cradek> what languages?
[02:54:22] <jepler> everything but portuguese, it looks like
[02:54:42] <cradek> you mean you want a picture of each of them?
[02:55:01] <jepler> I think that for the thumbnails, I cropped the upper 250x350 area and scaled 50%
[02:55:33] <cradek> can you do that? I don't have tools installed
[02:55:38] <jepler> sure
[02:55:43] <jepler> I'll update them all
[02:55:51] <jepler> that bug doesn't exist on this machine
[02:59:51] <SWPadnos> hmmm - was there a kernel change (since a week ago)?
[03:00:02] <SWPadnos> it doesn't look it, unless the name is identical
[03:00:14] <SWPadnos> (in the grub menu)
[03:00:36] <LawrenceG> cradek.... the positionfonts are broken still in the new mini package
[03:00:48] <cradek> SWPadnos: there was a kernel change on 02-19
[03:01:07] <cradek> LawrenceG: I don't think ray ever checked in any fix
[03:01:16] <SWPadnos> ok. the grub menu item must have replaced the old -magma kernel
[03:01:41] <cradek> yes it should not have made a new entry
[03:01:44] <SWPadnos> ok
[03:01:50] <LawrenceG> cradek: ok... will put the change into this version and test it
[03:02:01] <cradek> LawrenceG: can you put it in cvs?
[03:04:32] <cradek> LawrenceG: I think ray said mini uses a complex scheme with multiple resource files
[03:06:59] <LawrenceG> cradek: checking to see if the old mod works... very slow editing on P200
[03:08:06] <cradek> if your editor can't run on 200MHz you need a different editor!
[03:17:17] <LawrenceG> tfmacz: working on mini
[03:17:48] <tfmacz> LawrenceG, getting anywhere
[03:20:12] <asdfqwega> Would anyone be at all interested in a gcode->dxf converter written in Python?
[03:20:33] <LawrenceG> asdfqwega: YUP!
[03:20:58] <SWPadnos> possibly, though I'd imagine that dxf->gcode would be more useful ;)
[03:21:09] <asdfqwega> Well, too bad...I can't DCC SEND over my ISP :P
[03:21:12] <SWPadnos> for many people, anyway
[03:21:35] <asdfqwega> Hey, I'm just getting started...that's my next project
[03:21:43] <asdfqwega> among many others
[03:21:43] <LawrenceG> email to trashbag @ shaw.ca
[03:21:49] <cradek> asdfqwega: how does it represent things like dwells, canned cycles, helixes?
[03:21:49] <SWPadnos> heh
[03:22:03] <asdfqwega> it doesn't...
[03:22:15] <cradek> asdfqwega: just polylines?
[03:22:33] <asdfqwega> This was a case of an "aw shit'...I lost some drawings that I use CAMExpert to convert
[03:22:59] <cradek> ah, so anything is better than nothing
[03:23:01] <asdfqwega> I still had the gcodes, so I made something to convert back
[03:23:11] <SWPadnos> that's cool
[03:23:47] <cradek> did you figure out arcs? dxf polyline arcs are a nightmare
[03:24:04] <asdfqwega> [sighs] I really need to setup some webhosting for myself...
[03:24:21] <asdfqwega> I still haven't gotten arcs to work perfectly
[03:24:37] <asdfqwega> cause gcode works in points, and dxf uses angles for the endpoints
[03:24:50] <cradek> I wrote dxf->gcode arc code that works 100% - do you want it?
[03:25:16] <asdfqwega> so, some of the arcs are right, and the others have the right center/radius/endpoints, but they don't go 'round the right way
[03:26:04] <asdfqwega> I'll have to play with it a bit more
[03:27:00] <cradek> if you use polylines, you can use endpoint representation
[03:28:15] <cradek> for ease of editing I'd be tempted to make everything that's cut in g1/g2/g3 a polyline (g0 breaks into a new polyline)
[03:28:42] <cradek> of course nobody asked me...
[03:31:03] <asdfqwega> Nice thought, but it doesn't do me any good...Qcad doesn't have the best polyline handling just yet
[03:31:42] <cradek> ah, didn't think about that
[03:32:52] <asdfqwega> I've been eyeing PythonCAD as something to work on...but the interface need some real work
[03:33:43] <asdfqwega> Art Haas may have come up with a good collection of Python classes to make the core engine, but his taste in GUI stinks
[03:34:17] <Jymmm> asdfqwega: whats this gcode2dxf you were taking about?
[03:34:39] <LawrenceG> cradek: on line 1126 add the command setfontx on a line by itself. I dont have a cvs version co at the momentomment
[03:35:04] <cradek> http://timeguy.com/cradek-files/emc/blend-TESTING-2006-02-26.png
[03:35:10] <asdfqwega> Jymm: a quick hack I've written over the past week
[03:35:20] <cradek> I think this blending looks really quite decent now
[03:35:36] <cradek> LawrenceG: ok... trying
[03:35:38] <Jymmm> asdfqwega: So, are you just bragging, or do we get a peek at it too?
[03:35:41] <Jymmm> =)
[03:36:54] <LawrenceG> cradek: that looks like a nice blend
[03:38:52] <cradek> LawrenceG: how do I know if mini looks right?
[03:39:26] <LawrenceG> without the fix, the 3 position displays are regular size text
[03:39:36] <cradek> ok, they are bigger now
[03:40:14] <LawrenceG> with the fix, you should get whatever bigger font is the default.... you can change that in the ini file
[03:40:26] <CIA-8> 03cradek * 10emc2/tcl/mini.tcl: font fix from LawrenceG
[03:40:30] <LawrenceG> in the display section
[03:40:38] <cradek> ok, it looks right then
[03:40:38] <cradek> thank you
[03:40:50] <LawrenceG> cradek: Thankyou....
[03:40:59] <cradek> it's at least twice as tall as the other letters
[03:41:16] <asdfqwega> Jymm: quitcher bitchen, and gimme a moment to make some html and upload the dang thing
[03:41:26] <Jymmm> asdfqwega rotf
[03:41:41] <cradek> crap, nobody fixed help/about in mini
[03:41:50] <cradek> oh well
[03:44:02] <jepler> axis 1.2rc1 released. http://axis.unpy.net/index.cgi/downloads/01141010654
[03:44:12] <cradek> argggggh
[03:44:17] <SWPadnos> heh
[03:44:44] <SWPadnos> does this latest deb use cycle counts or nanoseconds for the tmax parameters?
[03:45:54] <cradek> I think cycles
[03:46:20] <SWPadnos> I gues sit doesn't matter on this 1 GHz CPU though ;)
[03:46:30] <cradek> ha, guess not
[03:48:51] <jepler> cradek: argh because you just built an axis package?
[03:49:04] <cradek> yes, it's the same except the version number
[03:49:47] <jepler> does it take long to build?
[03:49:53] <jepler> or is it your users you feel sorry for?
[03:50:00] <SWPadnos> * SWPadnos is a sorry user
[03:50:18] <cradek> no, it's not hard, just a little tedious
[03:50:24] <cradek> and the users!
[03:50:34] <SWPadnos> waaaaahhh
[03:50:38] <cradek> see!?
[03:51:09] <SWPadnos> I can't believe this. I'm switching to Windows and Mach3
[03:51:18] <SWPadnos> you people and your frequent updates
[03:52:41] <SWPadnos> so where's the update already?
[03:52:44] <SWPadnos> :)
[03:52:58] <cradek> new emc2-axis package in the ubuntu repository
[03:53:12] <jepler> yay
[03:54:03] <SWPadnos> heh - fetched 190kB in 1s (101kB/s)
[03:54:09] <SWPadnos> funny math there
[03:55:17] <SWPadnos> yeah - I've got a changed about box now. w00t!
[03:55:24] <SWPadnos> (whatever that means)
[03:57:38] <SWPadnos> on that note, I think I'll get to bed.
[03:57:42] <SWPadnos> good night, guys
[03:57:48] <SWPadnos> SWPadnos is now known as SWP_Away
[03:58:06] <SWP_Away> oh, and it seems to work just fine (still), after the system upgrade
[04:02:58] <cradek> great
[04:03:55] <asdfqwega> Jymm: http://www.bright.net/~janfritz/gcode2dxf.html
[04:05:06] <cradek> what is sdxf?
[04:05:32] <cradek> oh
[04:05:34] <cradek> * cradek reads the screen
[04:08:20] <asdfqwega> sdxf is OK, but if I make other projects I really want something better...
[04:08:35] <asdfqwega> So much to do and so little time
[04:08:52] <cradek> it looks like a useful starting point
[04:11:16] <Jymmm> asdfqwega got it, will check it out later.
[04:45:49] <asdfqwega> Okay...time for sleep.
[04:46:18] <asdfqwega> Oh, and Jymm? It was a laser.
[05:03:52] <LawrenceG> cradek: any chance you can add cp1 to the emc2 package? I noticed its missing from the latest stuff.
[09:15:21] <cncuser> hello
[10:28:08] <alex_jon1> alex_jon1 is now known as alex_joni
[13:17:45] <fenn> holy crap ubuntu is retarded
[13:18:07] <fenn> i screwed up my sudoers trying to add the NOPASSWD flag, and now i cant sudo to fix the damn thing
[13:18:13] <fenn> and i cant su to root either
[13:42:39] <fenn> solution: boot to recovery mode and use "visudo" next time
[13:42:45] <jepler> fenn: You can boot in rescue mode .. er, yes
[13:42:49] <jepler> fenn: good advice on both counts
[13:43:00] <jepler> fenn: I did that to myself on an ubuntu install too
[13:43:14] <fenn> they cant expect people to take warnings seriously.. come on
[13:43:34] <jepler> fenn: Learned about both "visudo" and "sudo -e" (edit arbitrary file as root) after that, so I benefited from the experience.
[13:43:43] <fenn> at least rename it to like.. the_real_sudoers and /etc/sudoers says "edit the real sudoers with visudo.. idiot!!"
[13:45:14] <jepler> then you'd just put 'alias "vi /etc/sudoers" "vi /etc/the_real_sudoers"' in your bashrc
[13:45:26] <jepler> (and patch bash so that works)
[13:45:44] <fenn> what if i dont use vi?
[13:45:54] <fenn> visudo has a striking similarity to nano, btw
[13:46:19] <jepler> It probably respects $EDITOR and/or $VISUAL, unlike the name implies.
[13:46:48] <fenn> it uses the DWIT interfac
[13:47:34] <jepler> whenever I accidentally start nano to edit something, I get flustered, f**k up the file with vim movement characters, then accidentally write the buffer and exit
[13:48:24] <fenn> 'alias "nano" $EDITOR'
[13:48:39] <fenn> that'd probably confuse the hell out of anyone
[13:53:10] <jepler> giacus: I hope you could help me with the translation of AXIS into Italian. Is there something shorter that could be put on the tabs, instead of Controllo manuale and Codice manuale? http://axis.unpy.net/files/translations/axis-it.png
[13:53:24] <jepler> giacus: I'm interested in any other suggestions you have
[13:53:49] <giacus> hi jepler
[13:53:52] <giacus> sure
[13:54:12] <jepler> hi giacus
[13:55:16] <giacus> for what I seen gui strings are 100% translated ok
[13:55:55] <giacus> for others, I can help , sure
[13:56:33] <jepler> I think the translation is probably pretty good--it was done by some italians--but I'm bothered that the strings on the tabs are too long and wanted another alternative.
[13:57:10] <giacus> I just played a bit around it, today I'm busy to solve an issue with Ati drivers and latest 2.6.15 kernel, 3d accel do not work :/
[13:57:48] <giacus> but sure, I can check Axis for translation in It
[13:58:06] <jepler> giacus: AXIS runs pretty good even on machines without 3d accel
[13:58:19] <giacus> oh.. isnt for that
[13:58:39] <giacus> I ned 3d accell in this machine to run vmware and cad/cam
[13:59:05] <giacus> after latest kernel upgrade I found 2 issues
[13:59:15] <giacus> first was with the dma, solved
[13:59:30] <giacus> second is with ati and 3d accell
[13:59:44] <giacus> now tryng to solve that ..
[13:59:46] <jepler> giacus: If I change the tabs to say "Controllo [F3]" and "Codice [F5]", does that still make sense in italian?
[14:00:26] <giacus> uhm
[14:01:04] <giacus> some word seems to be similar to english mean, however it doesnt
[14:01:36] <giacus> give me some day to play with it, and I will be able to suggest you the best terms to use
[14:01:59] <jepler> OK
[14:03:19] <giacus> * giacus back to #ati ..
[14:03:22] <giacus> later
[14:03:58] <jepler> thanks for helping
[14:04:11] <fenn> i think "manuale [f3]" would be fine
[14:04:25] <giacus> ty for developing Axis ! hehe ;P
[14:06:14] <jepler> you're welcome.
[14:06:17] <jepler> bbl
[15:41:08] <cncuser> hi folks
[15:41:21] <cncuser> alex_joni: whats the url of the new linuxcnc site again ?
[15:41:21] <jepler> hi cncuser
[15:41:26] <cncuser> hi jhepler :)
[15:41:31] <cncuser> -h
[15:41:56] <cncuser> alex_joni: ah, forget it, got it :)
[16:08:59] <cncuser> alex_joni: are you tehre ?
[16:09:37] <cncuser> alex_joni: there is some bug in joomla. yesterday i allready translatet the Downlaod Information. today its gone :(
[16:10:19] <cncuser> alex_joni: haha, forget thatone too ;)
[16:10:23] <cncuser> ok, im off :)
[17:54:06] <bill2or3> Does this look decent to power some steppers? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7593973235
[17:55:31] <Jymmm> It's regulated, but if you only need 24VDC looks like a good deal.
[17:55:39] <Jymmm> You sure oyu only need 24VDC?
[17:59:36] <Jymmm> bill20r3: His description almost implies that he has more of those PS's, you could get like 4 of them, that would give you 48VDC @ 3.6A -or- 48VDC@7.2A -or- 96VDC@3.6A -or- 24VDC@14.4A =)
[18:00:15] <Jymmm> he's got 100% feedback too, that's always a good thing.
[18:01:02] <Jymmm> Most folks dont use regulated, but you probably could just bypass that part of them.
[18:01:15] <Jymmm> if ever needed
[18:20:28] <bill2or3> I haven't found really *any* powersupplies > 24v and 3 or so A.
[18:20:55] <fenn> just get a big transformer, a big cap, and a bridge
[18:21:06] <fenn> i found one at the scrapyard on my first try
[18:21:07] <bill2or3> originally I was looking for something like 36V and 10A, but I think I'm gonna end up with 3 lower-amp supplies, and use one for each stepper.
[18:21:28] <bill2or3> I'd like >24v, but I dont seem to be finding it.
[18:21:43] <fenn> 24v is the industrial standard voltage
[18:21:49] <bill2or3> also, I just totally screwed myself by waiting 1-2 seconds too late to snipe an ebay auction.
[18:21:56] <fenn> haha
[18:22:01] <bill2or3> lost 4 THK bearing trucks for like $4/ea
[18:22:06] <bill2or3> :-(
[18:22:09] <fenn> wow
[18:22:16] <fenn> loser :)
[18:22:17] <bill2or3> yeah, I'm not pleased with myself.
[18:22:27] <Jymmm> bill20r3 you waited till the last 10 seconds?
[18:22:45] <bill2or3> Jymmm, apparently I waited until the last -1 second.
[18:23:02] <bill2or3> usually I like to bid at like 3 seconds, but I guess I caught a bit of network lag.
[18:23:16] <Jymmm> bill20r3: OUCH, if bidding manually, no less than 60 seconds, then you have a chance to rebid if needed.
[18:23:40] <bill2or3> I put the bid at the max I'll pay, so I dont re-bid.
[18:24:12] <Jymmm> bill20r3 you weren't willing to pay $10/each truck?
[18:26:58] <bill2or3> I was bidding at $16/per
[18:27:01] <bill2or3> but I bid too late.
[18:27:16] <Jymmm> I meant your initial bid
[18:28:56] <bill2or3> oh, I didn't want to run it up.
[18:29:00] <Jymmm> Unless the auction/item was questionable, even $20/ea seems reasonable.
[18:30:03] <bill2or3> yeah. my bid price was fine, it's my timing that sucks.
[18:39:16] <Jymmm> Hmmm.... I wonder if two of those would be enough current 48VDC@3.6A for geckos
[18:40:18] <Jymmm> what you think fenn?
[18:40:45] <bill2or3> I'm not so concerned about speed at this point, really.
[18:40:55] <bill2or3> unless 24v is going to be just snail-slow.
[18:42:16] <Jymmm> I have 24vdc switching now, but plan on getting geckos eventually.
[18:42:36] <Jymmm> 48VDC will be fine for me, it's the current I'm quesiotning.
[19:10:01] <bill2or3> ugh.
[19:10:15] <bill2or3> I guess I need to find a 5v source too, for the drivers.
[19:10:23] <bill2or3> can I just tap some off the PC for that?
[19:11:05] <jepler> bill2or3: two easy ideas are USB power (5V, 500mA), or for drive voltages no bigger than 30V you can use a 7805 linear regulator
[19:11:26] <jepler> bill2or3: PS/2 port (keyboard or mouse) can also give 5V at 100+mA
[19:12:24] <bill2or3> I'll probally solder some wires to a molex and run then out one of the card slots.
[19:15:20] <Jymmm> I'd avoid at all costs tapping USB.... way too tempermental
[19:15:36] <Jymmm> grab 5VDC off one of the PC's drive cables
[19:15:47] <Jymmm> then you have like 10amps available
[19:16:16] <jepler> This site gives 275mA as the available currentfrom the PS/2 port. http://www.computer-engineering.org/ps2protocol/
[19:16:39] <Jymmm> jepler It's much easier and safer to grab it off a drive cable
[19:16:45] <jepler> 6.3V "filament" transformer + 7805 is another easy way to get regulated 5V
[19:17:20] <Jymmm> Heck you can even use a wallcube
[19:17:37] <Jymmm> I'd hate to blow a mobo over 10mA
[19:18:05] <bill2or3> good point
[19:19:10] <jepler> no argument from me on that point
[19:19:12] <Jymmm> bill2or3 and dont solder a molex connector, just get a Y cable and clip off what you need
[19:19:34] <Jymmm> then you can just crimp connect a longer cable as needed
[19:19:44] <Jymmm> y cable is only a buck or so
[19:19:46] <jepler> heck, bring the standard 4-pin molex connector out to the back panel
[19:19:55] <Jymmm> yep
[19:23:12] <jepler> though it seems like you'll still damage your motherboard if you accidentally short the "+5V" to your 48V stepper motor supply.
[19:23:15] <bill2or3> yeah, that's what I mean, I'd solder wires to a female connector and plug it in.
[19:23:39] <bill2or3> but I'll just find some wallwart+7805.
[19:27:26] <Jymmm> jepler well can't account for stupidity, but at least it isn't 10mA =)
[19:27:56] <Jymmm> plus you get to see a nice 10A spark/arch
[19:27:59] <Jymmm> -h
[19:28:13] <Jymmm> so at least there's a light show =)
[19:31:52] <jepler> speaking of light show ... http://video.google.com/videoplay?docid=4468957986746104671&q=500kv
[19:32:16] <jepler> (via http://superpositioned.com/articles/2006/02/12/what-a-500kv-spark-looks-like)
[19:34:51] <Jymmm> LOL http://video.google.com/videoplay?docid=-1171246024685658304
[19:34:58] <Jymmm> that's fucked up
[19:35:49] <Jymmm> DAMNNNNNN --> http://video.google.com/videoplay?docid=-711022817903815072
[19:48:23] <tfmacz> Hello All... Can anyone help me with a question about emc2????
[19:49:36] <alex_joni> tfmacz: shoot
[19:49:55] <jepler> this is not a word. "suberban"
[19:50:07] <Jymmm> jepler heh
[19:50:50] <Jymmm> jepler: http://www.freedomunderground.org/memoryhole/pentagon.php
[19:52:23] <tfmacz> I know you guys are working on the trajectory blending problem. It ther a way to tur off trajectory blending so it goes straight into a corner???
[19:52:43] <alex_joni> tfmacz: yes, there is
[19:52:48] <alex_joni> Gsomething ;)
[19:52:52] <alex_joni> * alex_joni looks it up
[19:53:32] <cradek> I think it's g61
[19:54:01] <cradek> in the latest TESTING release, corners 90 degrees or sharper do not blend - the coordinates are hit exactly
[19:54:34] <cradek> that may be enough for what you want
[19:54:52] <cradek> assuming you do not want a decel/stop/accel on colinear blends
[19:55:04] <tfmacz> G61 ok O didn't realize it was actually a Gcode... I will bfing the box in from the shop later I need to cut this small part in a hury.
[19:56:16] <tfmacz> I di dthe update last night to the test box in the office here but have not done it to the controller i the shop....Thanks...
[19:56:50] <alex_joni> it G61 and G64 or something like that
[19:57:59] <tfmacz> The cuts are...plunge the Z and then take off at 90 degrees on some x-y path.
[19:59:18] <cradek> yeah it's not obvious whether that kind of thing should blend or not. in your case probably not
[19:59:39] <cradek> also up to safety height, over, back down - you usually don't want to blend, because you can hit the work
[19:59:56] <cradek> it's not clear to me what the right default behavior is
[20:00:26] <tfmacz> I can't find reference to G61 or G64???
[20:00:56] <jepler> tfmacz: http://www.isd.mel.nist.gov/personnel/kramer/pubs/RS274NGC_3.web/RS274NGC_33a.html#1013869
[20:02:00] <tfmacz> Thanks...bookmarked that puppy
[20:02:27] <jepler> that document has everything except the new "O codes"
[20:03:16] <tfmacz> Off to the shop to make some chips. Piles and piles of chips...
[20:03:18] <cradek> and those are on the wiki now
[20:03:20] <jepler> good luck
[20:03:54] <jepler> cradek: Maybe any change from feed to traverse, or traverse to feed, should be treated as "exact path"
[20:04:46] <fenn> up over down is all traverse
[20:04:56] <cradek> true
[20:05:05] <alex_joni> jepler: maybe it should be treated as "exact path" when "exact path" is specified ;)
[20:05:18] <fenn> maybe you need a new mode
[20:05:23] <SWP_Away> maybe G0 should never be blended with non-collinear moves
[20:05:23] <alex_joni> and "exact_stop" when "exact_stop" is specified
[20:05:27] <fenn> and stop slavishly following the kramer document
[20:05:36] <alex_joni> same for "continuous"
[20:05:43] <alex_joni> fenn: why so?
[20:06:00] <cradek> alex_joni: I think exact stop and continuous modes already work
[20:06:10] <alex_joni> fenn: other than rebellic attitude
[20:06:11] <cradek> I'm not sure about exact path
[20:06:18] <SWP_Away> SWP_Away is now known as SWPadnos
[20:06:21] <fenn> alex_joni: default should be "best guess" mode, and if you dont want it to guess, you set constant velocity or exact path
[20:06:26] <cradek> I hardly see the point of exact path
[20:06:38] <alex_joni> cradek: laser cutting
[20:06:42] <fenn> alex_joni: if you're going to go guessing that is
[20:06:54] <alex_joni> guess not ;)
[20:06:54] <SWPadnos> by default, there is already a setting in the modal group G61-G64(?), so no guessing would ever happen
[20:07:14] <fenn> cradek: you mean exact stop?
[20:08:38] <cradek> fenn: oops yes
[20:09:25] <fenn> by guessing i was referring to stopping at angles sharper than 90
[20:10:21] <alex_joni> cradek: seems 'exact path' takes care of what I had in mind
[20:10:30] <alex_joni> 'exact stop' is very obscure
[20:10:35] <SWPadnos> there's always a stop at sharper angles, since at least one axis has to reverse
[20:10:52] <cradek> SWPadnos: that's true, but with blending on, the stop can be nowhere near the specified point
[20:10:56] <alex_joni> exact path will behave as exact stop on any angles
[20:11:09] <alex_joni> just collinear moves won't stop
[20:11:21] <SWPadnos> yep - responding to fenn's comment - there is always a stop, might as well put it at the specified point
[20:11:34] <cradek> SWPadnos: that was my thinking.
[20:11:40] <SWPadnos> good thinking ;)
[20:11:52] <cradek> SWPadnos: that's obvious (?) for 180 degree reversals, but how about 170 degree?
[20:12:04] <fenn> i dont see what reversals have to do with anything
[20:12:06] <cradek> SWPadnos: herein lies the problem
[20:12:27] <cradek> g1x0 g1x1 g1x0 may as well go to x=1
[20:12:36] <cradek> how about g1x0 g1x1 g1x1y.001
[20:12:45] <cradek> that's what I mean
[20:12:52] <cradek> err
[20:12:54] <cradek> crap
[20:13:05] <cradek> how about g1x0y0 g1x1 g1x0y.001
[20:13:22] <cradek> should that go to x1, or should it blend?
[20:13:59] <fenn> howbout g6eleventy.1 "maximum angle considered a corner"
[20:14:01] <SWPadnos> it probably doesn't need to blend, but I'd have to think about it more to be sure of that
[20:14:29] <cradek> fenn: I actually could do that.
[20:14:45] <fenn> autotrace has some parameter like that
[20:16:18] <jepler> based on the remark that lines+arcs can be done at top speed in exact path mode, what we need is a gcode preprocessor that turns sequences of G1s into G1+G[23]s with the right parameters
[20:16:50] <jepler> pre-blending, in effect
[20:17:15] <cradek> jepler: I agree totally
[20:17:23] <fenn> uh, not really
[20:17:27] <jepler> then we just wait for cradek to add exact path mode to simple_tp
[20:17:33] <fenn> if you limit your maximum velocity to a certain speed, then yes
[20:17:38] <cradek> jepler: you bet I'll do it
[20:17:56] <cradek> and accel of course
[20:18:02] <jepler> cradek: I've needed a good reason to finish g2g, maybe this is it
[20:18:16] <fenn> what's g2g?
[20:18:27] <Jymmm> good2go?
[20:18:44] <cradek> gcode to gcode converter I think
[20:19:10] <fenn> for optimizing segment ordering or something?
[20:19:21] <fenn> nearest neighbor type stuff
[20:20:45] <cradek> mac's project looks interesting (users list)
[20:21:02] <Jymmm> anyone read Kanji?
[20:21:12] <cradek> many japanese people do I'm sure
[20:21:20] <cradek> sorry
[20:21:26] <Jymmm> and chinese. but any of there here?
[20:22:30] <fenn> yeah
[20:23:00] <fenn> Jymmm: sock it to me
[20:23:10] <Jymmm> fenn: http://www.byzant.com/images/symbols/chinese/friendship.gif
[20:23:45] <fenn> "domo" in japanese
[20:23:56] <Jymmm> that's 'stupid' iirc
[20:24:21] <Jymmm> or that's "stupid" in Korean
[20:24:31] <Jymmm> domo that is
[20:24:46] <fenn> "u" in chinese? i'm not good reading chinese/japanese transliterations
[20:25:07] <Jymmm> that makes three of us =)
[20:26:14] <Jymmm> fenn any ideas on this one? http://www.formosa-translation.com/chinese/p/pp217.html
[20:26:21] <fenn> korean uses phonetic spelling btw
[20:26:32] <Jymmm> ah, didn't know that.
[20:26:48] <fenn> what are you wanting to know specifically?
[20:26:51] <fenn> if it's correct?
[20:27:32] <fenn> that's "seikou" in japanese
[20:27:35] <Jymmm> fenn: two things... 1) is it correct (wouldn't want to be cussing someone out) and 2) I see two symbols, not one. that I dont get
[20:28:03] <fenn> the symbol on the right is a building and a strong arm
[20:28:46] <Jymmm> this one is 3 http://www.formosa-translation.com/chinese/p/pz28.html
[20:29:32] <fenn> heh plant names are always funny
[20:30:02] <fenn> what kind of grass grows around the campsite or something like that
[20:30:36] <Jymmm> Ok, BOTH of these are suppose to be 'friendship' --> http://www.formosa-translation.com/chinese/f/ff168.html and http://www.byzant.com/images/symbols/chinese/friendship.gif
[20:32:38] <fenn> the left character i believe means "friend" and the right is a combination of language, house, and .. (appearances?)
[20:32:55] <Jymmm> I suspect 'yi' is relationship, then when you lookup 'relationship' yeow! http://www.formosa-translation.com/chinese/r/zr037.html
[20:34:10] <fenn> ok some characters i pick out... brother, love, smoke, person + thread
[20:34:26] <Jymmm> ah, your right... 'yo' is 'friend' --> http://www.formosa-translation.com/chinese/f/ff166.html
[20:35:03] <Jymmm> are you picking those out as Japanese or Chinese ?
[20:35:12] <fenn> um.. chinese i guess
[20:35:22] <fenn> i dont know chinese, but i know what the characters mean sometimes
[20:35:28] <fenn> they're pictures after all
[20:35:47] <fenn> lots of times there are literary allusions and word games though, and it doesn't make any sense
[20:36:31] <Jymmm> Like syaing 'good morning' to your wife, your boss, or children, all different
[20:37:41] <fenn> http://www.kotoba-project.com/moreonkanji.html
[20:37:53] <fenn> skip down to section 2
[20:38:36] <Jymmm> oh, different dialect
[20:39:48] <fenn> i'm sure it would all make more sense if i knew chinese
[20:40:09] <fenn> fortunately your brain doesnt need to understand really in order to read it
[20:40:17] <fenn> like.. what makes an "a" an a?
[20:40:37] <fenn> i guess it's an upside down cow skull
[20:40:47] <fenn> so what
[20:41:34] <Jymmm> It appears that if you look at the characters on this page http://www.byzant.com/symbols/chinese.asp then grab the first chaaracter from the other webiste, they match
[20:41:57] <fenn> i should hope so
[20:42:15] <fenn> there are about 10 different ways to say "love" in chinese though
[20:42:23] <Jymmm> only 10?
[20:42:28] <fenn> i dunno probably more
[20:43:08] <fenn> haha i bet there are idiot christians with "god" in chinese tattooed on them
[20:43:11] <Jymmm> big diff here... tranquility http://www.formosa-translation.com/chinese/t/tt141.html http://www.formosa-translation.com/chinese/t/tt141.html
[20:43:19] <fenn> but it doesn't mean the same thing at all
[20:43:27] <Jymmm> lol
[20:43:42] <fenn> jymm thats the same url
[20:43:57] <fenn> anyway the simpler one makes more sense
[20:43:58] <Jymmm> http://www.byzant.com/symbols/chinese.asp
[20:44:09] <fenn> it's a pregnant woman under a roof
[20:44:40] <Jymmm> and thats tranquility huh?
[20:44:42] <Jymmm> lol
[20:45:15] <fenn> the other one's like "the feeling when drinkin from a cup" and blue skies and (something)
[20:46:34] <fenn> hmm my kanji dictionary doesn't like it
[20:46:35] <Jymmm> Shit... maybe I should muck up the symbols... in english "Harmony", in Kanji "MAy your sister get herpes"
[20:47:16] <Jymmm> then a lil disclaimer "Not repsonsable for translation errors"
[20:47:21] <cradek> is some idiot getting a tattoo in a language they don't speak?
[20:47:36] <Jymmm> cradek dont they always
[20:47:38] <fenn> heh i love it.. "buy this symbol"
[20:47:55] <Jymmm> San Francisco --> http://www.formosa-translation.com/chinese/s/szz204.html
[20:48:05] <fenn> just look it up in a chinese <-> english dictionary like kanjidic and copy the characters
[20:48:33] <fenn> it'd be different if they actually drew the characters out by hand, but no..
[20:48:40] <fenn> just wanna make a buck
[20:49:42] <Jymmm> http://www.excite.co.jp/world/english/
[20:50:21] <CIA-8> 03alex_joni * 10emc2/nc_files/skeleton.ngc: need T0 with single M6, to unload tool
[20:51:33] <fenn> Jymmm: http://www.csse.monash.edu.au/~jwb/wwwjdic.html
[20:54:05] <Jymmm> aw hell... can't copy n paste from browser to app =(
[20:54:21] <fenn> on second thought.. the excite page is probably better
[20:54:40] <fenn> too many weird obscure things show up on jdic
[20:54:49] <Jymmm> tell me about it
[21:01:14] <Jymmm> Ah, there we go... had the fontface but never knew the name of it.
[21:02:52] <Jymmm> I dont know how much overhead there'd be, but kanji looks like it'll vcarve nicely
[21:03:32] <fenn> yes i think it would.. there are tons of fonts out there too
[21:03:51] <fenn> what web browser do you use btw?
[21:04:01] <Jymmm> fwiw... 'MS Mincho' and 'MS PMincho' Mozilla
[21:04:38] <Jymmm> I go to enough .jp website, that I have the font face enabled
[21:05:02] <fenn> ok if you get gobbledygook you can select View->Character Encoding and play around with those until it looks right
[21:05:07] <Jymmm> they always have these itty bitty tiny computers that are so cool
[21:05:20] <fenn> heh japan is nuts
[21:05:33] <jepler> Yeah, sometimes I want an itty bitty computer
[21:05:33] <fenn> you have no idea
[21:06:01] <Jymmm> Well, they do have tubs you cna rent to sleep in too there, so...
[21:06:03] <Jymmm> tubes
[21:09:38] <Jymmm> fenn thanks for the help, I think I'm going to built up a lil library of symbols
[21:10:55] <Jymmm> so I can dump them to vector format whenever I want
[21:13:51] <jepler> Jymmm: the so-called "hershey" fonts have vector versions of some japanese characters. I'm having a little trouble finding a good page on the hershey fonts at the moment, but google a bit and you should find the (strangely-encoded) vector data.
[21:14:57] <cradek> Jymmm: I think you could also use truetype-tracer to get outlines from a ttf font
[21:16:44] <fenn> jepler: is "hershey" just outlines? or is it in correct stroke order?
[21:16:55] <jepler> fenn: It's just vectors, I doubt they're in the right order
[21:17:04] <jepler> fenn: you mean the order a human would draw the strokes in, right?
[21:17:21] <fenn> yeah
[21:17:35] <fenn> nevermind i was hoping for too much
[21:17:43] <Jymmm> Let me say this one as jog real quick...
[21:17:47] <Jymmm> Let me say this one as jpg real quick...
[21:18:14] <fenn> i know there are stroke-order data sets out there for kanji.. my pda wont understand if you write it in the wrong order
[21:18:26] <fenn> but all the documentation's in japanese.. so, heh.
[21:21:00] <fenn> i think a calligraphy robot would be pretty darned cool
[21:21:18] <fenn> for roman character sets too

[21:23:34] <Jymmm> fenn whats wrong with it?
[21:23:55] <fenn> it's just really mechanical

[21:24:44] <Jymmm> love.chinese http://www.formosa-translation.com/chinese/l/ll148.html
[21:25:11] <Jymmm> ok, I see what you mean about the strokes not being fluid
[21:25:35] <fenn> * fenn looks around for some good fonts
[21:26:07] <Jymmm> hmmm, let me try the other one and see if it's any better....
[21:26:12] <fenn> oh boy there are a lot of other fun languages to try too
[21:26:26] <fenn> like sanskrit, thai, etc
[21:26:39] <Jymmm> No, same thing =(
[21:26:44] <fenn> oh heh :)

[21:31:11] <fenn> that first one's really nice
[21:31:38] <fenn> ah damn its gone
[21:32:26] <Jymmm> http://musashi.or.tv/ttedit.htm
[21:33:37] <Jymmm> fenn I can't read it well enough to navigate
[21:36:03] <fenn> http://musashi.or.tv/aoyagikouzanfont.htm
[21:37:20] <Jymmm> http://www7a.biglobe.ne.jp/~kouzan/
[21:37:58] <fenn> thats just some dude named kouzan
[21:38:11] <fenn> the font's on that page i just posted
[21:38:54] <Jymmm> what are the diff betwene those 4 and then the 2 ?
[21:39:03] <fenn> i guess he's the one that wrote the characters
[21:39:25] <fenn> the first 4 are truetype the second 2 are opentype.. dunno google and find out
[21:39:46] <fenn> truetype was started by adobe/apple
[21:39:59] <Jymmm> I know what open type are, but of the TFF ones, the diff between the 4
[21:41:00] <bill2or3> http://www.allelectronics.com/cgi-bin/item/PS-017/480/3-OUTPUT_24VDC_POWER_PLATFORM_.html
[21:41:07] <bill2or3> that looks just right.
[21:41:08] <bill2or3> I think.
[21:42:02] <Jymmm> fenn : DUH! lol --> http://translate.google.com/translate?u=http%3A%2F%2Fmusashi.or.tv%2Faoyagikouzanfont.htm&langpair=ja%7Cen&hl=en&safe=off&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools
[21:42:40] <fenn> no wonder i didnt get it.. the second one is in "semi-cursive"
[21:43:27] <fenn> not line-book
[21:43:38] <Jymmm> fenn: Did I ever tell you I'm a font whore?
[21:43:46] <fenn> no, but i could've guessed
[21:44:08] <Jymmm> fenn: I must have about 300K+
[21:44:28] <fenn> google translation's pretty darned good
[21:44:34] <fenn> 300 thousand fonts?
[21:44:38] <Jymmm> fenn not bad for beta
[21:44:55] <Jymmm> fenn: Yeah, my clipart collection is over 1M
[21:45:36] <fenn> well hey at least you do something with it
[21:46:23] <Jymmm> fenn: Well, sorta, but not really. I do almost nothing with the fonts, except store them. the clipart can be very difficult to just browse sometimes.
[21:48:01] <Jymmm> If I find a good font, it gets installed. But giving folks a choice of fonts is down right scarry
[21:48:44] <Jymmm> I'm ALWAYS looking out for chunky fonts, they seem to be hard to come by.
[21:53:43] <Jymmm> need to eat, then will test new fonts
[21:56:59] <fenn> chunk whore
[22:01:09] <bill2or3> this looks ok too: http://www.mpja.com/productview.asp?product=15367+PS
