[00:00:26] <Goslowjimbo> ipsi/ispi
[00:18:51] <Goslowjimbo> How do I check to make sure comp is working?
[00:32:26] <Goslowjimbo> geo01005: did I read you had figured out how to generate bit files?
[03:18:34] <cradek_> stustev: got the hub off, yay
[03:19:14] <cradek_> stustev: the seal is a rubber part in a pressed-in metal part, and it split between the two, so the wrong part was turning.
[03:19:30] <cradek_> not sure how I will get it out yet, but it's in the (air conditioned!) shop now
[03:22:06] <cradek_> now if only I could get my network connection fixed...
[03:22:46] <jmkasunich> made the big socket?
[03:22:51] <cradek_> yep
[03:24:16] <cradek_> I cut in the end of a 5x3x12? block - it was only two opposite corners
[03:24:35] <cradek_> then I used two bigass (tm) pipe wrenches (thanks for the idea Jymmm) to turn it
[03:24:41] <cradek_> well, that and a sledge hammer
[03:25:21] <jmkasunich> so I guess it was kind of tight?
[03:25:47] <cradek_> yeah the locking nut was - the inner one was only finger tight
[03:29:50] <Jymmm> cradek_: np, but might want to thank Mother Tersa instead...
[03:30:17] <Jymmm> We, the unwilling, led by the unknowing, are doing the impossible for the ungrateful. We have done so much, for so long, with so little, we are now qualified to do anything with nothing.
[03:30:18] <Jymmm> -- Mother Teresa
[03:39:01] <eric_unterhausen> actually by Christopher Hitchens
[03:42:53] <eric_unterhausen> trying to adjust a Buck tru-adjust chuck
[03:43:43] <eric_unterhausen> sorry, adjust-tru
[03:44:09] <cradek_> if you adjust-tru at one diameter, is it adjusted tru for others?
[03:45:32] <eric_unterhausen> it's a 6 jaw chuck in combo with something like a 4 jaw chuck
[03:46:03] <tomp> tomp is now known as tom3p
[03:46:17] <eric_unterhausen> if the scroll is off, you aren't gonna be tru anyway
[03:46:57] <eric_unterhausen> oh well, read the instructions again, now down to the man-cave
[05:22:19] <jimbo655> Verey quiet. Oh well here goes. Hal for the 5I20 I am assuming that in-00,01,02 are the same as 24,25,26 in Mesa's terms?
[05:25:46] <awallin> there was a table in the manual
[05:26:04] <awallin> for the old hal_m5i20 driver, but I don't know if that was removed now...
[05:26:33] <jimbo655> I did not see a Table I will go look....
[05:33:00] <jimbo655> Can you use VI to edit the HAL file directly?
[05:52:09] <micges> logger_dev:
[05:52:17] <micges> logger_dev: bookmark
[05:52:38] <micges> logger_emc: bookmark
[05:52:38] <micges> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-06-27.txt
[07:28:44] <roh> hm.. how does one set hal-params from a custom M-code?
[07:41:37] <KimK> roh: would this help? (I've been working on that too, as it happens) http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?M100-199
[07:52:32] <roh> only partially
[08:08:47] <micges> roh: what params do you want to set?
[15:29:36] <skunkworks> Hmm - I don't feel 36 today. ;) A bunch of auto-emails for message boards reminded me.
[15:30:01] <archivist> har har
[15:30:41] <archivist> yo iz stll kidz though
[15:31:27] <skunkworks> *from
[15:32:01] <skunkworks> heh - I don't know when time started speeding up - but it just seems like a few months ago I turned 30
[15:32:04] <skunkworks> ;)
[16:20:11] <mozmck> is git down?
[16:20:26] <SWPadnos> probably
[16:20:52] <SWPadnos> chris and his provider have been troubleshooting a connection problem for a couple of days
[16:21:02] <mozmck> I get a timeout trying to pull
[16:21:03] <mozmck> ok
[16:57:18] <awallin> any c++ gurus around?
[17:00:10] <awallin> hm, maybe I'm coping...
[17:03:57] <awallin> how are different operators called when I do 3.0*myObj compared to myObj*3.0 (I got the latter to work, but not the former)
[17:04:30] <awallin> do I have to add my own method to the double class? that would seem silly
[17:08:56] <SWPadnos> you might be able to overload your operator* with a variant that takes (double, myclass&) rather than (myclass&,double)
[17:08:59] <SWPadnos> but I'm not sure
[17:09:31] <awallin> I'll try...
[17:09:50] <SWPadnos> I don't know if it's possible though
[17:10:27] <SWPadnos> I believe that the operator* from the first type gets called with a ref to that variable then the other one
[17:10:53] <SWPadnos> good luck with it, I've got to run now :)
[20:34:57] <pcw> Cow-orker brought in a robot torque motor (local surplus place had a bunch)
[20:34:58] <pcw> 3 phase variable reluctance stepper and 3 phase variable reluctance resolver
[20:35:00] <pcw> Really interesting (Resolver looked just like stepper just on its own laminations)
[20:35:01] <pcw> resolver is 4 wire star, reference drives star center, and position is sensed by
[20:35:03] <pcw> differences in 3 leg currents
[20:36:33] <archivist> hmm what would they be like for a rotary
[20:38:09] <pcw> Probably a LOT of torque
[20:41:00] <archivist> I was watching a youtube video of a sliding head lathe and that goes from spinning at speed to stationary for live tooling to mill, been wondering on the motors used
[20:41:38] <pcw> Looked like maybe 50-100 electrical phase rotations/ turn
[20:41:40] <pcw> just like a giant step motor
[20:41:41] <pcw> I wonder if the lathe is just done with a brake
[20:43:15] <archivist> dont think so as it does co-ordinate work as well
[20:45:43] <archivist> http://www.youtube.com/watch?v=Ep0crJUFEIc&NR=1 at about 1:28 they engrave the barrel
[20:51:19] <pcw> Wow, thats a fancy machine.
[20:51:21] <pcw> An oversized servo as the spindle drive maybe?
[20:51:40] <archivist> thats more likely probably
[20:53:06] <pcw> The Sodick machines are impressive also,
[20:53:08] <pcw> all linear motor axis on some models
[20:53:46] <archivist> seeing the Citizen in the flesh was nice, I want to do an emc one
[20:54:16] <pcw> Well find an old one....
[20:54:43] <archivist> there is a mechanical one 30ft from me
[20:55:08] <archivist> major mods needed though
[20:55:09] <pcw> Thats a lot more work...
[20:55:40] <archivist> can see me ever affording a scrap cnc one though
[20:55:44] <archivist> cant
[20:56:44] <archivist> http://www.archivist.info/cnc/works2008/P1010226.JPG
[20:57:00] <pcw> Three seems to be tons of 80s and 90s CNC stuff in the USA being retired and sold for near scrap
[20:57:02] <pcw> prices as we deindustrialize
[20:57:26] <pcw> (there)
[20:58:13] <archivist> scrap price and my price are still far apart
[20:58:36] <pcw> :-)
[21:00:06] <pcw> What are those rocker-arm thingies on the top?
[21:00:39] <archivist> they come from the cams on the lower left
[21:01:50] <tomp> i /part
[21:02:49] <archivist> you can see one cam disk in front of the working area, the rest are hidden
[21:05:46] <pcw> So thats a fully automatic mechanical screw machine?
[21:06:37] <archivist> sliding head auto, designed for long thing parts
[21:06:44] <archivist> thin
[21:09:22] <pcw> Like the Citizen?
[21:09:25] <pcw> Is that collet on the Citizen just tight enough
[21:09:26] <pcw> to let the stock slide but not wobble?
[21:10:08] <pcw> Or does it grab the stock when in place
[21:10:12] <archivist> yes exactly, there is a gripper collet behind to advance and pin it
[21:10:25] <archivist> pin/spin
[21:15:09] <pcw> I like watchihg CNC videos
[21:15:10] <pcw> Years ago when we plotted our PCB layouts
[21:15:12] <pcw> on mechanical plotters I wasted lots of time
[21:15:14] <pcw> watching the plotter...
[21:16:03] <archivist> youtube is a time sink
[21:16:10] <pcw> Yep
[21:18:01] <archivist> good one though
[21:23:08] <tom3p> i cant save message filters on thunderbird. it generates a java exception (~file not found). is this same for other users running ubuntu 8.04 from live emc cd?
[23:39:12] <eric_unterhausen> somebody email me a boring bar
[23:42:00] <eric_unterhausen> I think there are more boring bars on ebay than anything I've ever searched for before
