Back
[00:06:25] <jmkasunich__> it's called "plug reversing", and yeah, its is stressfull
[00:06:37] <jmkasunich__> on the contactors or switch, if nothing else
[00:09:02] <jmkasunich__> jmkasunich__ is now known as jmkasunich
[03:31:23] <cradek> greetings from the shop (used to be known as: the garage)
[03:31:29] <cradek> I have network now
[03:33:32] <cradek> also, autocad runs (much) faster on a pentium 133 running dos than in qemu on a 2+ GHz system
[03:36:48] <SWPadnos> how recent is your qemu install?
[03:38:58] <cradek> the one in the dapper repo
[03:39:07] <SWPadnos> ok
[03:39:09] <cradek> there's a kernel thing but I've tried it a few times, and it makes no difference
[03:39:21] <cradek> (I think it has/had a weird license too)
[03:39:22] <SWPadnos> apparently kqemu was released as open source earlier this year
[03:39:26] <cradek> yeah that
[03:39:40] <SWPadnos> right - I think the stupid licensing is over now
[03:39:46] <cradek> it didn't make any difference for me when I tried it
[03:40:21] <SWPadnos> I wonder how well KVM works
[03:40:26] <SWPadnos> and how to set it up
[03:40:33] <cradek> I haven't heard about that one
[03:40:40] <SWPadnos> http://en.wikipedia.org/wiki/Kernel-based_Virtual_Machine
[03:40:44] <cradek> I'm not complaining really - it works fine for me
[03:40:46] <SWPadnos> that's the one in the kernel now :)
[03:40:50] <cradek> I'm just shocked by how fast it is in real dos
[03:41:01] <SWPadnos> on a Matrox card?
[03:41:04] <cradek> (I did lots of real work with this version of autocad on a 486-66)
[03:41:15] <cradek> no, the acad vesa driver on some CL chip
[03:41:22] <SWPadnos> a Pentium is a pretty hopping DOS chip
[03:41:36] <SWPadnos> ok, CL-GD5420 or some such
[03:41:36] <cradek> yes
[03:41:40] <cradek> and a 133 is a fast pentium
[03:42:19] <SWPadnos> oh, true if it's not a pentium-mmx
[03:42:52] <SWPadnos> I think the fastest was 200 Mz or thereabouts
[03:42:55] <SWPadnos> MHz
[03:44:00] <cradek> funny that this laptop is 10-15 years newer than the mill it's hooked to, but still 10 years old
[03:44:25] <cradek> it's a glorified serial terminal that also happens to run autocad to generate gcode
[03:45:38] <cradek> hmm, it got late
[03:45:45] <cradek> I should get to bed "early" tonight...
[03:45:48] <cradek> so, goodnight
[03:46:03] <cradek> hope the mach threads are worn out by tomorrow :-)
[03:46:20] <SWPadnos> heh - good night
[12:03:46] <Guest461> I must have a different definition of rigid tapping..
[12:03:52] <Guest461> Guest461 is now known as skunkworks_
[12:16:17] <cradek_> yeah well I still hope the thread dies soon
[12:18:28] <cradek_> cradek_ is now known as cradek
[12:18:35] <skunkworks_> good morning
[12:18:45] <cradek> hi
[12:19:50] <cradek> arguing about mach capabilities on emc-users is stupid
[12:20:13] <cradek> but it does show that people have different ideas what the things in those kinds of comparison tables mean - so you can't trust them too much.
[12:20:48] <alex_joni> good morning
[12:20:54] <skunkworks_> exactly.
[12:20:59] <cradek> hi guys
[12:21:16] <skunkworks_> I actually figured he would come back and tell about his gali or such controller run by mach
[12:22:59] <skunkworks_> Hi alex
[12:26:03] <cradek> some of the things on the table don't fit emc well (like questions about steps per second) because some configs don't have steps at all
[12:27:03] <cradek> or "number of switches"
[12:27:27] <cradek> those are questions that make sense only for less flexible software
[12:27:53] <cradek> I should go to work ... bbl
[12:33:23] <skunkworks_> alex_joni: did you see you where trying to do a nigerian scam on cncuser ;)
[12:34:49] <alex_joni> yup .. unfortunately I saw that
[12:34:51] <alex_joni> :/
[12:35:57] <skunkworks_> odd that they would get your name perfectly... I wonder if he is infected with some sort of trojion
[12:36:22] <skunkworks_> morning ray.. Get some rain?
[12:37:17] <skunkworks_> we got a good inch and it looked like it was heading your direction.
[12:40:12] <alex_joni> skunkworks_: nope, my account is gone though
[12:41:44] <rayh> Hi guys. Lots of rain
[12:45:06] <skunkworks_> it just poured here yesterday around 4:00
[12:46:38] <rayh> It messing up your building plans any?
[12:47:28] <skunkworks_> No. that is stalled. The guy that was going to do the floating slab figured out he couldn't do it. (too much elevation change) So I need to get someone in to do frost walls.
[12:47:54] <skunkworks_> hope to atleast have the pad before winter.
[12:48:56] <rayh> Ah. We made 2' wide by 4' deep frost walls on our shop.
[12:49:24] <skunkworks_> yah - that is what we are looking at doing.
[12:49:47] <skunkworks_> (not 2' wide though - maybe 8 inches - whatever they normally pour.)
[12:50:01] <skunkworks_> sitting on a footing
[12:50:55] <rayh> phone
[12:53:48] <skunkworks_> alex_joni: ?
[13:47:29] <alex_joni> hmm, this is interesting:
[13:47:53] <alex_joni> http://www.etherlab.org/en/ethercat/index.php
[13:48:12] <alex_joni> it's an industrial bus over ethernet, with RT extension (they claim RTAI works too)
[13:51:15] <alex_joni> sounds like it can fit perfectly into HAL
[14:33:26] <alex_joni> bll
[14:33:27] <alex_joni> bbl
[15:18:14] <skunkworks_> http://youtube.com/watch?v=8T6_nFt-VeM&mode=related&search=
[15:18:27] <skunkworks_> he got the nurbs working (I lost track of that)
[15:20:29] <cradek> heh that is not a fast moving machine :-)
[15:20:39] <skunkworks_> no :)
[15:21:00] <cradek> wow, 4 ipm
[15:21:26] <cradek> I wonder why he doesn't want to contribute his nurbs changes
[15:21:43] <cradek> few people would use them, but I don't see what it would hurt
[15:22:17] <skunkworks_> right - if the cam software is able to do it...
[19:14:02] <cradek> I should try CSS + G33 for scroll cutting
[19:14:11] <cradek> I think it would work
[19:26:53] <skunkworks_> well - now it can die.. I have driven my point in as far as it will go.. but I think it just isn't gotten.
[19:28:14] <cradek> good
[19:29:24] <cradek> I still suspect he's somehow mistaken, but I don't really care about that
[19:29:58] <cradek> clearly you need very good synchronization to do rigid tapping and not break things
[19:30:11] <SWPadnos> he's equating rigid tapping with using a CNC tapping head, and there's no way anyone will convince him there's a difference
[19:30:23] <SWPadnos> which there isn't, if you hawve a floating tap holder
[19:30:52] <SWPadnos> cradek, thanks for pointing jlmjvm in the right direction. I don't have the time at the moment
[19:31:29] <cradek> I don't have the patience to handhold today, but he'll figure it out
[19:31:35] <SWPadnos> I hope so
[19:31:38] <cradek> that kind of thing is very basic hal knowledge
[19:32:21] <SWPadnos> it is a problem that you can't see what the right thing to do is, unless you do it before editing the hal file, or after removing the changes you made
[19:33:10] <cradek> I reread steve's messages - he said he uses a tapping head, and he read that "someone else" rigid taps "regularly"
[19:33:18] <SWPadnos> yep
[19:33:18] <cradek> so, the argument is silly
[19:33:25] <SWPadnos> indeed it is
[19:34:35] <SWPadnos> it's only important because people have a negative impression of EMC based on what they read on the lists/forums, and a positive impression of Mach from the same places. these impressions aren't really related to the merits of the programs unless people post corrections to inaccurate claims
[19:35:49] <SWPadnos> also, the specs we tend to claim for EMC are a worst case or baseline (like 20kpps), whereas the specs claimed for Mach are more like peak performance
[19:36:23] <SWPadnos> ok. breakfast/lunchtime - I finally got some activity out of the 5i22 :)
[19:36:33] <skunkworks_> COol!
[19:36:56] <SWPadnos> yeah
[19:37:27] <SWPadnos> what a nightmare that was last night (at 3AM) when I couldn't even get PateW's hostmot2 config to do anything
[20:12:52] <jepler> SWPadnos: yay
[20:14:43] <skunkworks_> jepler: how is the zenbot?
