[00:09:50] <PCW_> PCW_ is now known as PCW
[02:22:48] <PCW> bbl
[14:40:57] <jepler> hum, running xst in fakeroot fails on one of my systems (8.04, 32-bit) but succeeds on another (8.04, 64-bit)
[15:47:45] <CIA-81> EMC: 03seb 07master * reb57c6c842ad 10/src/hal/drivers/mesa-hostmot2/encoder.c: don't set enc.vel to NaN
[15:49:52] <skunkworks_> oh - figured out?
[15:51:20] <cradek> not from the looks of it
[15:53:53] <skunkworks_> darn ;)
[16:04:20] <jepler> why do people keep talking about nans? In the one screenshot I saw it was an inf, not a nan -- http://imagebin.ca/view/BpN9pD0.html
[16:04:36] <jepler> 1./0. -> inf
[16:39:19] <skunkworks_> in school we learned it as undefined ;)
[16:43:05] <skunkworks_> seb!'
[16:52:17] <cradek> sweet - today my enco free ups shipping code gave me free "truck" shipping. last time I tried, it didn't.
[16:52:36] <micges> hello
[16:52:43] <cradek> hi micges
[16:53:19] <micges> one thing I had chance to check is that oth jitters on "nan machine" are about 10000
[16:54:29] <micges> both
[16:55:04] <cradek> micges: have you seen halscope say nan, or is it always inf like this image shows? http://imagebin.ca/view/BpN9pD0.html
[16:56:00] <micges> hard to say
[16:56:27] <micges> I know that may be important but I don't remember
[16:56:43] <cradek> ok
[16:57:26] <micges> I have a lot of work, give me chance to test your patches and questions
[17:09:39] <seb_kuzminsky> micges: if you upgrade to top of tree it will include a new & better patch i just committed, that logs when it sees the problem, but does not change vel from the previous servo loop
[17:11:19] <micges> cool
[17:12:53] <micges> I know that nan machine has your first patch from december, not sure about second one you and cradek prepared
[17:14:20] <micges> sorry november
[18:48:22] <LawrenceG> cradek, do know anything about this version of hardinge lathe? is it cnc? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250561337647
[18:48:57] <LawrenceG> they say automatic, but it doesnt look fully cnc'd
[18:50:29] <cradek> doesn't look nc to me, more like an automatic turret lathe
[18:51:09] <LawrenceG> built in 1969, so whatever is automated would not be very advanced
[18:51:14] <cradek> but no, I don't know anything about it
[18:51:39] <LawrenceG> this group seems to have bought all the good lathes!
[18:51:40] <cradek> yeah I'm pretty sure that's before nc and electric servos
[18:52:53] <LawrenceG> the closest lathes I have found are 1250 miles away in California
[18:53:39] <cradek> where are you?
[18:53:55] <LawrenceG> off the west coast of Canada
[18:54:42] <LawrenceG> lots of tree eating machines here but very little in the way of metal fab
[18:54:53] <cradek> hmm.
[18:55:40] <cradek> have you tried looking in portland or?
[18:56:12] <cradek> still far, probably
[18:56:46] <LawrenceG> Seattle and Portland are within a days drive... But the east coast seems to have most of the ebay listings
[18:59:51] <LawrenceG> your new mill looks sweet.... a little easier to use coolant with than the bridgeports (shower curtain required)
[19:00:22] <cradek> thanks yeah, the big bucket shape is great
[19:00:37] <cradek> it gets exactly none on the floor, all in the trough
[19:01:03] <LawrenceG> and the high speed spindle is a big plus
[19:12:44] <skunkworks_> cradek: any issues rigid tapping with the v-belt connection?
[19:16:21] <cradek> I have only done a few, but it seems fine
[19:16:26] <cradek> it's actually a flat belt, not a V
[19:17:45] <skunkworks_> ah
[19:17:48] <skunkworks_> neat :)
[19:26:04] <PCW> http://cgi.ebay.com/1980-HITACHI-SEIKI-3NE300-CNC-LATHE-FANUC-SCREW-PARTS_W0QQitemZ230431104121QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a6c39c79
[19:26:06] <PCW> theres a cheap time sink (california)
[19:27:04] <cradek> was that cowgirl the previous owner?
[19:30:57] <LawrenceG> from the wording.. that may be just for a part of the machine.... wonder what blew up?
[19:32:31] <PCW> Yes I guess misread, not clear what you get
[19:32:47] <PCW> (probably not the cowgirl)
[19:33:07] <LawrenceG> its a little large to fit in the pickup!... maybe the cowgirl is selling the OM's lathe
[19:35:30] <LawrenceG> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250571863497 probably low hours with a high crash rate
[19:40:17] <PCW> You'd think most CNC machines of any age have experienced a few crashes
[23:08:46] <LawrenceG> yay 2 #80 holes drilled..... scratch 1 bit.... 1000rpm is a bit slow for a #80 drill in the tailstock
[23:12:44] <skunkworks_> what is with the ping timeouts?bunny
[23:12:53] <skunkworks_> wtf?
[23:12:55] <skunkworks_> heh
[23:20:05] <alex_joni> bunny?
[23:20:17] <alex_joni> that's a new typo even for skunkworks_
[23:21:05] <skunkworks_> well - The old typos get old.
[23:21:13] <skunkworks_> ;)
[23:22:40] <cradek> fun in lincoln, and you all missed it: http://journalstar.com/news/local/education/article_fae8d340-107b-11df-a90b-001cc4c03286.html
[23:23:12] <cradek> (but I didn't go either)
[23:24:45] <skunkworks_> heh
[23:26:40] <skunkworks_> bbl
[23:51:19] <jt-plasma> anyone know where I laid my 12 awg ferrules down, you know the gray ones...
[23:56:29] <jepler> I think the cat knocked them on the floor
[23:58:40] <jt-plasma> that is always a possibility, however I think the only solution is to clean up until I find them :/
