[00:39:12] <cradek> looks interesting
[00:39:40] <cradek> I'm so used to hand-editing I don't think I'm your target, but I bet it would be useful for others
[00:45:55] <cradek> http://timeguy.com/cradek-files/emc/jr.jpg
[00:46:26] <cradek> finally got most of the guards back on
[00:51:11] <cradek> hm, tool change quill up sure doesn't work right
[00:52:08] <skunkworks> very nice looking :)
[00:53:34] <cradek> I only made it operate - cosmetics were thanks to my co-conspirators
[00:54:05] <cradek> (and they did a great job)
[00:54:33] <cradek> bet your shop doesn't have a skylight!
[01:00:03] <skunkworks> heh - no. darn it all
[12:24:49] <CIA-82> EMC: 03jthornton 07v2_3_branch * rc708221c581a 10/docs/src/hal/ (3 files in 2 dirs): Expand a bit on the net description and some markup fixes
[12:26:00] <CIA-82> EMC: 03jthornton 07master * rc977494fbab5 10/docs/src/hal/ (3 files in 2 dirs): Expand a bit on the net description and some markup fixes
[13:10:32] <Dave911> cradek: Is that a Mori Seiki Jr mill? Like the ones that were linked on here the other day? That looks really nice. I can see how getting it in there might have been a challenge.
[13:18:49] <skunkworks_> logger_dev: bookmark
[13:18:49] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2009-10-20.txt
[13:22:18] <cradek> Dave911: yep
[13:22:47] <SWPadnos> heh. machine stuff all over the place, and one lone VGA cable in front of the tool box :)
[13:23:04] <cradek> Dave911: took two days to get it from the garage to this shop corner
[13:23:14] <cradek> SWPadnos: darn, I meant to give that to jepler
[13:23:19] <SWPadnos> heh
[13:23:46] <skunkworks_> cradek: is that the probe mounted to the pendon support?
[13:24:08] <cradek> yes - it has CAT40 shank so can't go through the tool changer - I load it manually
[13:24:13] <skunkworks_> ah
[13:24:27] <cradek> I figured "up high" was a good place to keep it safe
[13:24:56] <cradek> I may try to make a BT40 shank for it after I get coolant going
[13:25:18] <Dave911> Are you happy so far with that mill? I was considering buying a bridgeport CNC but that Mori Seiki looks a lot more capable.. and with the price of machines right now why not go for the best avail..
[13:25:30] <cradek> yes, it is a very good machine
[13:25:43] <cradek> all linear rail, oversize ball screws with four circuits each
[13:26:04] <cradek> low inertia servos, very high acceleration
[13:26:23] <Dave911> How much does that weigh? Those specs are way better than Bridgeport..
[13:26:36] <cradek> about 8k lb I think
[13:26:56] <cradek> also BT40 taper so tooling is everywhere, unlike the bridgeports
[13:27:30] <cradek> brb
[13:28:36] <Dave911> Not too bad. I've seen some decent machines going for 25-30 cents per pound. Crazy cheap. I am near MI also, the hub of economic destruction and chaos - so they are dumping machines up there as apparently the chinese have their own machines already. :-(
[13:29:46] <Dave911> Did you buy that machine locally?
[13:31:43] <Dave911> Any problems tying the existing servo drives into EMC2?
[13:38:09] <Dave911> http://cgi.ebay.com/Mori-Seiki-MV-Junior-Vertical-Machining-Center_W0QQitemZ390063845165QQcmdZViewItemQQptZBI_Mills?hash=item5ad19def2d
[13:38:11] <Dave911> 80 miles away..... These guys actually want some decent money for this machine though.. although in normal times that would still be a good price.
[13:41:50] <SWPadnos> it seems so much like a Wednesday already
[13:44:12] <skunkworks_> it's not wednesday?
[13:44:27] <SWPadnos> my electronic calendars tell me it isn't
[13:55:31] <cradek> existing servo drives are plain old analog velocity mode
[13:56:00] <cradek> I had two bad drives (ugh) but that's because it was a dead machine
[13:58:00] <cradek> interesting - that one is a fanuc - mine was yasnac
[13:58:10] <cradek> lower control panel is the same, upper panel with crt is different
[13:58:22] <cradek> that might be the reason for the higher asking price
[13:59:43] <cradek> also 20 tools instead of 16?? bizarre.
[14:06:55] <alex_joni> cradek: where's the keyboard?
[14:07:03] <cradek> alex_joni: no keyboard
[14:07:22] <alex_joni> touch?
[14:07:27] <cradek> yes touchscrene
[14:07:33] <cradek> een
[14:07:44] <alex_joni> cool.. so using a virtual keyboard for text input?
[14:08:29] <cradek> no, I wrote a gui that doesn't need a keyboard
[14:08:41] <alex_joni> ha :P
[14:09:11] <cradek> haven't decided yet if/when/how to share it
[14:09:21] <alex_joni> bbl
[14:09:24] <jepler> it's written in BCPL#
[14:09:34] <cradek> and lisp
[14:09:51] <alex_joni> right.. gotta have lisp
[14:10:59] <SWPadnos> interesting: http://www.evidence.eu.com/content/view/313/390/
[14:20:59] <cradek> oops: http://bbs.homeshopmachinist.net/
[14:21:20] <jepler> linux sucks
[14:21:33] <SWPadnos> it's clearly not ready for the web
[14:37:46] <skunkworks_> cradek: what does the gui look like? (if you are serious)
[14:38:27] <cradek> skunkworks_: specifically made for touch screens - big buttons - no keyboard needed to run it
[14:43:37] <skunkworks_> Neat
[14:48:34] <cradek> skunkworks_: http://timeguy.com/cradek-files/emc/touchy-mdi.png
[14:50:40] <skunkworks_> hey - look at that. very neat. Nice work. (do you still have the axis like preview/plot somewhere?)
[14:50:49] <cradek> nope
[14:51:11] <skunkworks_> WHAT!? ;)
[14:52:38] <cradek> I write gcode on the other computer at the desk (previewing in AXIS if needed) - by the time it's in the mill, I don't need the preview anymore
[14:52:42] <skunkworks_> has stuart seen it yet? I bet he would be all over it.
[14:52:55] <cradek> I showed him an early incomplete version
[14:53:54] <skunkworks_> It is very much what he was wanting. (he didn't see the need the preview)
[14:54:40] <skunkworks_> *for the
[14:56:07] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[17:52:50] <alex_joni> http://www.andyshelley.co.uk/emc/index.php
[17:53:07] <cradek> MY EYES
[17:53:44] <cradek> heh, clever hack, nice use of filter
[17:53:48] <jepler> yeah, exactly
[17:53:53] <jepler> exactly my thought
[17:55:34] <alex_joni> SWPadnos: something for you (maybe) http://www.freeholidaywifi.com/
[17:55:38] <SWPadnos> someone should point Stuart at that one
[17:56:27] <SWPadnos> alex_joni, darn. if only they had that on United
[18:24:01] <alex_joni> maybe they will ;)
[18:25:17] <SWPadnos> sadly, United and Lufthansa did a short-lived experiment with in-flight wi-fi several years ago, and ended the program
[18:25:33] <SWPadnos> it was cool to be on IRC while flying over the Atlantic though :)
[18:30:15] <alex_joni> "But he did say that Voltaire believes that the next step the switching industry will take is a move to 40 GE switches and that these will be used for inter-switch links and a number of years from now will move down into servers, much as Gigabit Ethernet did a number of years ago and 10 GE is doing now."
[18:30:25] <alex_joni> SWPadnos: different (more expensive) technology I bet
[18:30:52] <SWPadnos> could be
[18:30:55] <alex_joni> this looks like pretty basic wifi http://www.freeholidaywifi.com/inflight/
[18:30:57] <SWPadnos> 40GE sure is
[18:31:14] <alex_joni> that's a different topic ;)
[18:33:15] <SWPadnos> so it's 3G speed (at best), shared by any of the 160+ people onboard who are using their wifi enabled devices
[18:33:18] <SWPadnos> like all the iphone users
[18:33:40] <alex_joni> we get 7.2 MBps 3G over here
[18:33:52] <SWPadnos> :P
[18:34:10] <SWPadnos> bits or bytes?
[18:34:23] <alex_joni> bits
[18:34:33] <alex_joni> although the standard is up to 14Mbps
[18:34:42] <alex_joni> using HSPA+
[18:34:45] <cradek> you're sitting on a chair WHICH IS FLYING THROUGH THE SKY and you whine that you have to share a network connection with some other folks
[18:34:51] <SWPadnos> heh
[18:34:58] <SWPadnos> come on, think about it
[18:35:08] <SWPadnos> I mean, if I have a flying chair, I should also have a good internet connection
[18:35:25] <jepler> rocket car?
[18:35:30] <cradek> you lost me in your reasoning there
[18:35:31] <alex_joni> "As of August 2009, there are 12 HSPA+ networks running in the world at 21Mbit/s and the first 28Mbit/s network has been completed in Italy. "
[18:36:39] <SWPadnos> if technology is sufficiently advanced to allow my chair to fly, it should also be advanced wnough to give me good communications while flying
[18:36:43] <SWPadnos> enough
[18:38:07] <jepler> that's like saying that if we know how to make a good long island iced tea it should be easy to factor arbitrary large numbers
[18:38:23] <SWPadnos> agreed
[18:38:56] <SWPadnos> and it's similar to the argument that "we bought your expensive thing, so clearly we should be able to afford my expensive thing"
[18:39:32] <SWPadnos> e.g., absurd
[18:43:31] <alex_joni> heh
