[00:08:32] <Jymmm> Jacky^ I am now.
[00:09:23] <Jacky^> Jymmm: any idea about postal service cost US/EU for kg ?
[00:09:53] <Jymmm> http://usps.com/tools/calculatepostage/welcome.htm?from=home&page=0061calculatepostage
[00:10:02] <Jacky^> thanks
[00:10:05] <Jymmm> np
[00:10:56] <Jymmm> hey les
[00:10:59] <les> hi
[00:12:33] <Jacky^> hi les
[00:12:43] <les> hello jacky
[00:13:31] <les> bit of a slow day for me
[00:13:36] <les> which is fine
[00:13:49] <Jacky^> :)
[00:16:14] <Jacky^> les: wich slides you like for woodmachine ?
[00:16:28] <Jacky^> i'm looking for it ..
[00:17:45] <Jacky^> but maybe i'm oversizing it
[00:24:38] <les> 15 mm for small, as much as 40 mm for very large
[00:25:09] <les> I picked 25 mm for yogo's machine
[00:25:16] <les> yugo
[00:25:48] <Jacky^> i'm looking at hiwin website ..
[00:26:01] <Jacky^> but i think are very expensive
[00:26:02] <les> look at abba too
[00:26:28] <Jacky^> ok, thanks
[00:27:09] <les> jacky, 25 mm rail came out at about US$100/meter here...the blocks about $50 each
[00:27:17] <les> pretty reasonable
[00:27:49] <Jacky^> yeah
[00:28:05] <Jacky^> i think so
[00:28:09] <les> abba and hiwin are about half the price of most others
[00:28:14] <les> still good quality
[00:28:30] <Jacky^> what about skf ?
[00:28:37] <Jacky^> more expensive ?
[00:28:43] <les> ok, but cost more
[00:28:49] <les> double
[00:28:50] <Jacky^> ok..
[00:29:27] <Jacky^> for 1 mt lenght machine 25 mm is ok ?
[00:29:37] <les> sure
[00:29:40] <Jacky^> :)
[00:29:46] <les> even 15 would be fine
[00:29:59] <les> but 15 and 25 are almost the same price
[00:30:11] <Jacky^> nice ;)
[00:30:19] <Jacky^> better 25 then
[00:30:19] <les> go with 25 for better crashworthiness
[00:30:31] <Jacky^> ok
[00:30:52] <les> Surviving a bad crash with no damage is important
[00:30:59] <les> because it will happen
[00:31:11] <Jacky^> :\
[00:31:23] <les> 25 can handle 20kN+ loads
[00:31:47] <les> and only a tiny bit more cost
[00:32:15] <les> So better, right?
[00:32:18] <Jacky^> good
[00:32:54] <Jacky^> i'm a bit confused about some parameter.. like loads
[00:33:02] <Jacky^> first experience :\
[00:33:20] <Jacky^> anyway 25 mm should be a good choice
[00:33:26] <les> Well cutting loads are very low for wood
[00:33:29] <Jymmm> * Jymmm lol @ Jacky^ the rail virgin!!!!
[00:33:35] <les> haha
[00:33:39] <Jacky^> Jymmm: :D
[00:33:48] <Jymmm> Jacky^ (couldn't resist)
[00:33:56] <Jacky^> hehe
[00:33:59] <les> loads might be 100-200 n
[00:34:14] <les> so we design for worst case crash
[00:34:22] <les> to survive
[00:34:28] <Jacky^> understood
[00:34:41] <Jacky^> y axis couls also be the same ?
[00:34:48] <les> sure
[00:35:02] <Jacky^> good :)
[00:37:02] <Jacky^> i will stearting ordering the slides
[00:37:31] <Jacky^> start*
[00:37:58] <les> I still think about collecting my written material and writing a book on cnc router design
[00:38:02] <pc_op`> pc_op` is now known as pc_op
[00:38:08] <les> I think not enough would buy it
[00:38:18] <Jacky^> les: could be nice :)
[00:38:41] <les> sell 100,000 copies?
[00:38:45] <les> or 10?
[00:38:48] <Jacky^> heh
[00:38:56] <Jacky^> will be open source ?
[00:38:59] <Jacky^> :P
[00:39:10] <Jacky^> gpl*
[00:39:15] <les> heck no...charge big book price!!!
[00:39:17] <les> haha
[00:39:21] <Jacky^> :D
[00:39:24] <AchiestDragon> well found a small lathe thats cheep on ebay , hmmm bit too small i think http://cgi.ebay.co.uk/1-12-Scale-Engineering-Lathe-Materials-Castings_W0QQitemZ5996370686QQcategoryZ14737QQcmdZViewItem
[00:39:32] <les> looking
[00:40:35] <les> cute
[00:41:11] <les> I learned on a unimat one when I was 15 or so...it fit in a shoebox
[00:41:21] <les> wish I had it now
[00:42:00] <les> that looks like a jeweler's lathe really
[00:42:59] <AchiestDragon> the whole lathe is 6" long , nice working model though
[00:43:05] <les> Aw, but Dragon, just run out to the corner store and buy a nice Colchester
[00:44:21] <Jacky^> les: do you prefer 1 or 2 motors on x axis ?
[00:44:39] <les> uh oh...storms from Katrina...better check radar...brb
[00:45:49] <les> 2 is better but emc cannot do it
[00:45:59] <Jacky^> ok
[00:46:26] <les> I have to get off...blew all computer stuff last week...don't want it to happen again
[00:46:30] <les> storm
[00:46:40] <Jacky^> :\
[00:46:45] <les> later
[00:46:48] <Jacky^> bye
[01:04:57] <Jacky^> doh
[01:05:08] <Jacky^> already seen this: http://cgi.ebay.it/HYDRO-FOAM-Motoscafo-VOLANTE-Aereo-MOTORE-Brushless_W0QQitemZ5994420644QQcategoryZ2564QQrdZ1QQcmdZViewItem
[01:05:21] <Jacky^> nice video :P
[01:07:56] <Jacky^> it seem use a nice Brushless motor
[01:28:53] <Jacky^> Gnight

[04:04:41] <Jymmm> hola LawrenceG
[07:14:54] <Jymmm> hi Yuga A-L-P-H-A
[07:15:28] <A-L-P-H-A> hi
[07:15:34] <A-L-P-H-A> is http://www.mininova.org working for you?
[07:15:53] <Jymmm> no
[07:22:34] <A-L-P-H-A> Jymmm, thanks
[07:22:39] <Jymmm> np
[07:29:28] <Phydbleep> It looks like they're being dos'd..
[07:30:31] <A-L-P-H-A> no matter.
[07:30:35] <A-L-P-H-A> I found the magnet link. :)
[07:30:51] <A-L-P-H-A> magnet... fileless torrent links.
[07:32:16] <Jymmm> never heard of them

[10:30:19] <Jacky^> Morning
[13:30:38] <CR750> Good evening, EMC developer team. Thankyou for a great product. I have 4.08 up and running on my home made mill. 'tis great. I do, however, have a question you may be able to help answer- What should I be using (open source wise) to convert AutoCAD or Alibre drawings (or DXF) to NC codes?
[13:32:14] <cradek> http://timeguy.com/cradek/autocad
[13:32:54] <cradek> this lets you draw toolpaths using polylines and other entities, and generates g-code tailored for emc
[13:33:57] <CR750> I'll take a peek. Tx for your help.
[13:34:33] <CR750> And say "Hello" to Paul, who helped greatly during my recent upgrade from 2.18 to 4.08
[14:12:24] <CR750> Realize is loaded. (I'm not an AutoCAD expert) How do I "execute" it to get the ngc output?
[14:23:33] <cradek> type realize at the prompt
[14:32:42] <CR750> That done, and setting the layer name to 125-MILL results in only 5 lines in the c:\acad.t file.
[14:33:14] <cradek> read the last paragraph starting "In summary" under "How to use REALIZE"
[14:34:12] <cradek> in fact, it can't hurt to read the whole "How to use REALIZE" section
[14:34:28] <CR750> I did. Honest.
[14:34:41] <cradek> what are the Z coordinates of the things you selected?
[14:34:56] <CR750> It's a 2d drawing.
[14:35:13] <cradek> The x and y work in the obvious way. The z dimension determines the cutting depth. Therefore the z of all entities NOT on layer 0 must be negative.
[14:35:36] <cradek> you have to move it down in Z to specify the cutting depth
[14:35:47] <CR750> Is there a method of setting an existing entity to a minus depth?
[14:36:02] <cradek> move all 0,0,0 0,0,-1
[14:36:08] <CR750> Coll
[14:36:16] <CR750> I'm sure that's all I need do.
[14:36:21] <CR750> tx for the help
[14:36:24] <cradek> sure
[14:36:50] <cradek> I have had very little feedback since I released REALIZE - please let me know if it works for you
[14:38:27] <CR750> Magic.
[14:39:11] <CR750> My worse than poor understanding of AutoCAD is the most difficult part for me to overcome.
[14:47:47] <CR750> I'd like to continue to chat but it's 23:30. My last run of realize didn't generate all the nc code (confirmed by yetch WinCNC)
[15:33:55] <CIA-8> 03paul_c 07cradek_stable * 10emc/src/emctask/emccanon.cc: fix for Bugs item #1274108. coordinate offsets were not being applied to rotary axes for G2/3 moves.
[15:46:25] <les> arg get back here matt
[16:19:48] <ValarQ_> ValarQ_ is now known as ValarQ
[18:46:52] <Jymmm> Howdy Folks!
[20:40:03] <LawrenceG> .
[20:40:16] <Jymmm> Oh this is weird... My laptop sorta kinda works at 9.6VDC, depending on what/where you look this 9.6V replacement battery is suppose to work, and in other it's not. The original is 14.4VDC Li-ION the 9.6VDC is Ni-MH which I would rather have instead. damn
[20:40:48] <Jymmm> And I did a 'Buy It Now' based upon the info in the auction.
[20:40:56] <Jymmm> though, not paid for yet.
[20:41:24] <Jymmm> the auction was a lil ambigous and when I called them they couldn't confirm/deny it either way.
[21:21:02] <Jymmm> hey les: Got Lighting?
[21:33:55] <les> just tornadoes
[21:35:21] <les> weather is getting a little better
[21:36:11] <Jymmm> good to hear.
[21:36:15] <les> just searching true type fonts right now
[21:36:18] <les> for a sign
[21:36:53] <les> thousands of fonts, but seems like they all fall into just a few categories
[21:37:23] <Jymmm> les : http://dafont.com/
[21:37:32] <les> Also...decided to change the paint robot design
[21:38:12] <les> was using roundrails and rack for the telescoping arm
[21:38:16] <les> but
[21:38:40] <les> why not just bolt some racke to the base of a linear rail?
[21:39:47] <Jymmm> if you have it to spare, why not.
[21:40:05] <Jymmm> Else, a coupe hinges and some acme leadscrew
[21:40:21] <Jymmm> not like you need that much precision for painting... do you?
[21:41:37] <les> well the robot is to pick up the calls and put them in the drying rack
[21:41:59] <les> but might as well make it precise so it will have more uses
[21:42:07] <Jymmm> ah, ok.
[21:42:13] <les> not cnc precise
[21:42:18] <Jymmm> I was thinking only moving a spray gun.
[21:42:45] <les> but say 1mm positioning accuracy over a 1.5 meter circle
[21:43:08] <les> No this is a theta radius z arm
[21:43:25] <les> pick up something here, put it over there
[21:43:52] <lilo> [Global Notice] Good evening, all. We've resolved our segfault problems with 1.0.1 and will be upgrading to a new version which should be missing those problems. The high-impact part of the upgrade will be done early morning UTC. For more information, please see http://freenode.net/news.shtml .... thanks, and thank you for using freenode!
[21:43:53] <les> but the arm....
[21:44:05] <les> use 20 mm rail bolted to rack!
[21:44:46] <les> fast and cheap
[21:45:01] <Jymmm> heh
[21:45:40] <les> I have to work out the dynamics. I want it to be real fast
[21:46:18] <les> now...what else could I use such a thing for?
[21:46:37] <les> welding?
[21:46:46] <Jymmm> pancakes
[21:46:51] <les> heh
[21:47:18] <Jymmm> I'm serious... you could have a CNC pancake breakfast as a fund raiser and promotion.
[21:47:28] <les> yeah
[21:47:59] <Jymmm> kinda like a donut making machine
[21:48:50] <les> so vertical shaft in the center
[21:49:02] <les> long telescoping radius arm
[21:49:11] <les> and a z on the end
[21:49:39] <les> heck if it was stiff enough it could run a router
[21:49:49] <les> but that would cost too much
[21:50:09] <les> play chess....
[21:50:19] <les> hmm
[21:50:23] <les> what else
[21:50:36] <Jymmm> back massag
[21:50:38] <Jymmm> e
[21:50:45] <les> throw a laser on it?
[21:50:47] <les> haha
[21:51:10] <les> oh, can use the big machine for massage
[21:51:23] <les> but if there is a software error...
[21:51:37] <les> squashes you like a bug
[21:52:40] <les> oh that font site is good
[21:55:42] <Jymmm> =)
[22:39:18] <paul_c> mshaver: poke.
[22:43:48] <Jymmm> paul_c: peek.
[22:45:27] <paul_c> OK... Found the problem with BDI-4.23
[22:45:41] <paul_c> on to building BDI-4.24
[22:47:19] <Jymmm> paul_c: When you create a new release, does it usually have the 'latest and greatest' if the other parts? Like X, kde, etc ?
[22:47:26] <Jymmm> s/if/of/
[22:48:12] <paul_c> Sometimes.
[22:49:13] <paul_c> The build system is now set up to use Sarge, so if it is new there (and is in the package selections), it ends up on the CD.
[22:49:32] <Jymmm> Ah, well I apt-get install kvirc and it broke KDE. So then I apt-get upgrade konquerer and it installed like 256MB of crap and broke other stuff. Just fyi.
[22:50:02] <paul_c> with BDI-4.23 ?
[22:50:17] <Jymmm> 4.20
[22:50:52] <paul_c> well... That is six months out of date - Probably still using KDE-3.2 then.
[22:51:20] <Jymmm> Yeah, it attemped to do 3.3
[22:51:34] <Jymmm> thats why I asked if you update those things.
[22:52:33] <paul_c> 4.23 is built from the current (as of the 27th) Sarge.
[22:55:13] <Jacky^> Jymmm: look if you like this http://irssi.org/?page=themes
[22:55:51] <Jacky^> also work from console .. I love it
[22:59:04] <les> is Matt there?
[22:59:27] <Jymmm> paul_c: Ah, ok. Well when you get 4.24,5,6,7,etc I'll give it a shot.
[23:06:45] <Jymmm> Jacky^: I dont' care for it becasue I'm usually in mor ethan one channel at a time.
[23:06:57] <Jacky^> hehe..
[23:07:02] <Jymmm> I like to see ALL the channels
[23:07:30] <Jacky^> this mean you've not seen this..: http://irssi.org/themes/mine.png
[23:07:51] <paul_c> Jymmm: KSirc...
[23:08:02] <Jacky^> kvirc it's a toy ..
[23:08:37] <Jymmm> paul_c: ksirc has that annoying extra server window. KVIRC at least least you tile the windows easily. Much like mirc
[23:09:56] <Jymmm> paul_c: I noticed KVIRC becasue it's on the LIVE cd, but not on the BDI.
[23:12:20] <paul_c> Now that Sarge has gone "stable", problems with installing extras & breaking stuff should disappear.
[23:14:39] <Jymmm> very cool =)
[23:15:45] <paul_c> hrmm.. 1.4Meg for kvirc...
[23:16:15] <paul_c> and another 875K for kvirc-data
[23:16:47] <paul_c> & 210K for kvirc-doc
[23:18:48] <Jymmm> is there limited room available?
[23:22:49] <paul_c> limited room, yes. But I had hoped to use the space for "useful" tools & libs.
[23:23:25] <Jymmm> ah
[23:29:42] <paul_c> 725K for ksirc
[23:37:55] <Jymmm> Ok, only slightly smartass here.... but does anyone actually PRINT from BDI?
[23:38:18] <paul_c> me !
[23:38:31] <Jymmm> really?
[23:39:32] <Jymmm> ok, nm. Just was trying to recover 20MB =)
[23:40:30] <Jymmm> I wonder how knoppix is able to get 2BG worth on a single cd
[23:40:35] <Jymmm> 2gb
[23:41:41] <paul_c> compressed file system
[23:41:58] <Jymmm> is it a PITA do to?
[23:43:15] <paul_c> Oh yes.
[23:43:27] <Jymmm> ah, nm then
[23:43:38] <paul_c> time consuming, needs loadsa RAM & HD
[23:43:56] <Jymmm> paul_c: oh on that perms issue.... if I did sudo it worked fine.
[23:44:12] <paul_c> for $trivial_fs, it doesn't take too long...
[23:46:25] <Jymmm> whats the MAX iso file size?
[23:46:40] <Jymmm> my cdr's are 720MB (raw)
[23:50:14] <paul_c> I usually aim for ~650Meg
