[03:04:46] <CIA-8> 03jepler 07HEAD * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: DRO fixes: Use 3 decimals when displaying metric values, since we recommend specifying metric distances to 3 places. make everything line up. convert speed estimate to metric.
[03:05:17] <cradek> yay thanks
[03:05:55] <jepler> cradek: if you feel like it, check that DTG and Spd are right on a metric config...
[03:07:13] <cradek> ok
[04:44:33] <A-L-P-H-A> I hate how stupid my friend is. He types something, but doesn't give the statement context, or even grammatically comprehensible.
[04:45:50] <A-L-P-H-A> love how he can't spell as well. "worker not speake english every well leave busines card"
[04:46:02] <A-L-P-H-A> ahh... the joys of data entry.
[05:05:20] <alex_joni> morning
[05:08:56] <A-L-P-H-A> hi alex_joni
[05:10:40] <A-L-P-H-A> hi k
[05:16:19] <K`zan> Sigh, so much for fbsd, it won't see any of my extended partitions, sigh...
[05:51:58] <A-L-P-H-A> front teeth gaps look so ugly
[06:01:27] <K`zan> Night folks
[06:56:57] <anonimasu> MORNING
[07:56:50] <fenn> http://burningsmell.org/images/biollante-reinforced-joints.jpg
[19:51:53] <robin_sz> cradek: when you say "like mach" .. like which bits of it?
[19:52:21] <SWPadnos> the configurable GUI bit, I imagine
[19:52:27] <robin_sz> expect so
[19:52:50] <robin_sz> its one of the two good bits of mach
[19:52:50] <SWPadnos> I think you may be the several people who want it ;)
[19:53:17] <SWPadnos> (me too, for competitive / feature-comparison reasons)
[19:53:36] <robin_sz> HAL has addressed the other good bit of mach, to some extent anyway
[19:54:31] <robin_sz> overall, we have a system thats very very fully featured, very configurable .. and a GUI for a 3 axis mill
[19:54:55] <robin_sz> the HALVCP thing is a big step in the right direction IMHO
[19:55:52] <SWPadnos> sure, except that it doesn't control EMC (the interp / canon), it only affects HAL
[19:56:03] <anonimasu> hm is mach good?
[19:56:09] <SWPadnos> it is a step in the right (?) direction
[19:56:43] <SWPadnos> mach is good, if you want to run a machine with parallel port step generation only, and don't care about feedback / closed loop operation, and want to run under Windows
[19:57:06] <anonimasu> hm.. I heard something about lockup issues and stuff before
[19:57:11] <SWPadnos> the G-Rex will also be usable soon, and I think there are MODBUS or other interfaces for I/O, but not for motor control
[19:57:30] <SWPadnos> on my machine, it causes everything to slow down by a factor of 10 or so, maybe more
[19:57:48] <SWPadnos> so things like tooltips that would normally take a few seconds to appear take a minute or so
[19:57:59] <anonimasu> mach?
[19:58:02] <anonimasu> err mach3
[19:58:12] <SWPadnos> it's incompatible with WinAmp - you get endless skipping
[19:58:15] <SWPadnos> yes, Mach3
[19:58:20] <SWPadnos> on Windoes 2000
[19:58:22] <anonimasu> lol
[19:58:31] <anonimasu> you shouldnt run winamp on a machine to control a mill anyway
[19:58:53] <anonimasu> unless you are sure that it wont fuck up your parts :)
[19:59:00] <anonimasu> imo..
[19:59:01] <anonimasu> that is :)
[19:59:02] <SWPadnos> it won't on Linux ...
[19:59:03] <Lerneaen_Hydra> emc2 + xmms/amarok/other should work nicely :D
[19:59:08] <anonimasu> yeah
[19:59:25] <anonimasu> bbiab..
[19:59:37] <anonimasu> going to buy some cola..
[20:00:08] <SWPadnos> it has other interesting features as well, like a camera mode so you can find a part edge with a video window (and a camera mounted on the column / spindle)
[20:01:26] <cradek> is it somehow better than any camera viewing app?
[20:01:52] <cradek> seems like you could do that just as easily without any support in the controller
[20:02:22] <SWPadnos> that's true, but one of the "advantages" of mach is that you can just do all that stuff, without having to keep track of multiple programs
[20:02:53] <SWPadnos> for most users, it's much more important to have things work simply than it is to have something that can do everything, given enough effort
[20:03:11] <cradek> I shouldn't talk about this because I'll turn into a troll
[20:04:01] <SWPadnos> heh - I know :)
[20:04:03] <Lerneaen_Hydra> * Lerneaen_Hydra gives cradek a troll pill
[20:04:10] <SWPadnos> anti-troll pill, I hope
[20:04:18] <Lerneaen_Hydra> heh heh heh
[20:04:24] <SWPadnos> for "trollaxation"
[20:04:29] <SWPadnos> Trollium
[20:04:29] <cradek> it's good that there are different programs for people who like different things
[20:04:47] <cradek> just like there are different guis in emc. if they are all insufficient in some important way, maybe we need another one.
[20:04:58] <SWPadnos> I agree with you. I tend to prefer the unix-y way of doing things rather than the monolothic Windows way
[20:05:24] <cradek> if we need a web browser built into one, so someone can look up something on google without switching windows, so be it, I just don't see why people would expect it in AXIS
[20:05:45] <cradek> .... trying so hard not to troll
[20:05:56] <SWPadnos> the vast majority of computer-using machine people probably would prefer to be able to find the things they need on a menu in a single program (even if in the case of EMC2 the menu item runs a separate program)
[20:06:34] <SWPadnos> I'm not sure we have the ability to embed programs within any of the GUIs - which would be a good thing IMO (like the KDE control center or something)
[20:06:54] <SWPadnos> I guess TCL/Tk programs can be embedded by nature
[20:07:07] <robin_sz> anonimasu: the good bit about Mach is its configurable GUI, and its macros. the rest of it sucks to varying degrees. motion sucks a lot
[20:07:18] <jepler> you mean, by executing the scripts in the same interpreter? Yeah, but that sucks real bad
[20:07:33] <robin_sz> no
[20:07:53] <SWPadnos> macros written in VBScript or the like
[20:07:57] <jepler> swadnos: you mean, by executing the scripts in the same interpreter? Yeah, but that sucks real bad
[20:08:00] <SWPadnos> kind of like M101
[20:08:11] <robin_sz> yeah, the VB stuff. pity its VB, but the concept rocks
[20:08:13] <jepler> I was responding to the thing about embedding one tk app in another
[20:08:23] <SWPadnos> ah - I don't think I was talking about the interp
[20:08:51] <SWPadnos> more like having something like the tabs in Mini, but for semi-arbitrary external programs
[20:08:54] <jepler> There's "toplevel -use" and "frame -container" but they suck terribly
[20:08:56] <SWPadnos> like a video app, for instance
[20:09:04] <cradek> M1xx plus the python mdi program probably give you about as much as any VB scripting thing
[20:09:27] <SWPadnos> yep
[20:09:28] <jepler> cradek: if so we should show people how to use it
[20:09:29] <robin_sz> whatever, being able to write a script and hook it up to a button on the GUI and make things happen ... logic, machine motion, setting GUI leds on and off etc ...
[20:09:38] <jepler> I hate this conversation
[20:09:47] <SWPadnos> heh
[20:10:05] <SWPadnos> that is one approach :)
[20:10:08] <robin_sz> me, I have no time
[20:10:32] <cradek> I'm going to go get some coffee
[20:10:37] <SWPadnos> too bad the code you had written for this got lost (lament, not troll)
[20:10:51] <robin_sz> I only made a star
[20:10:52] <robin_sz> t
[20:11:00] <robin_sz> it was way WAY off complete
[20:11:07] <SWPadnos> well, a start is a start, and much easier to work with than nothing
[20:11:12] <robin_sz> shrug
[20:11:22] <robin_sz> lets talk about spot welders
[20:11:36] <SWPadnos> nah - too spotty a topic :)
[20:12:32] <Lerneaen_Hydra> * Lerneaen_Hydra slaps SWPadnos with a trout
[20:12:45] <SWPadnos> mmm - fishy
[20:21:35] <alex_joni> jepler: this might be the first time I see getting angry
[20:21:53] <alex_joni> * alex_joni wonders if he should read back on the conversation or just let it go
[20:22:02] <jepler> I'm sorry -- I overreacted
[20:22:14] <SWPadnos> alex_joni, robin / mach / configurable UI ... you know the story ;)
[20:22:28] <anonimasu> heh
[20:22:37] <anonimasu> jepler: it's ok.
[20:22:40] <alex_joni> I can picture the rest :)
[20:22:46] <anonimasu> jepler: I understand why you get annoyed.
[20:23:44] <anonimasu> besides, supporting everything is really hard.
[20:24:20] <Lerneaen_Hydra> jepler: sorry if I was a bit "do this", "code that", "make things the way I think it should be"
[20:24:34] <SWPadnos> yes, it's all your fault :)
[20:24:39] <anonimasu> lol
[20:24:41] <anonimasu> axis rocks :)
[20:24:54] <Lerneaen_Hydra> * Lerneaen_Hydra runs to a corner and cries
[20:24:57] <Lerneaen_Hydra> :p
[20:25:34] <skunkworks1> why can't we all be friends? -Group hug-
[20:25:42] <cradek> hahaha
[20:25:44] <anonimasu> * anonimasu slaps skunkworks witha eel
[20:25:44] <SWPadnos> old song
[20:25:54] <SWPadnos> Thank you, Doctor Leo ...
[20:26:17] <Lerneaen_Hydra> * Lerneaen_Hydra does *not* like the way #emc is degrading into a sterotypical irc channel ;)
[20:27:12] <alex_joni> skunkworks1: like the idea
[20:27:16] <alex_joni> * alex_joni kicks anonimasu
[20:27:21] <Lerneaen_Hydra> ...
[20:27:23] <alex_joni> anonimasu: the group hug is nice :D
[20:27:26] <anonimasu> haha yeah
[20:27:34] <Lerneaen_Hydra> define "hug"...
[20:27:46] <alex_joni> virtual embracement
[20:27:49] <alex_joni> ;)
[20:27:57] <Lerneaen_Hydra> in all forms and manners?
[20:28:01] <Lerneaen_Hydra> oh my
[20:31:39] <robin_sz> so this spot welder ...
[20:31:51] <SWPadnos> spot on
[20:32:01] <alex_joni> robin_sz: what sheet thickness?
[20:32:02] <robin_sz> I have it working now, without the tips annealing themselves in 50 welds
[20:32:08] <robin_sz> thin,
[20:32:15] <Lerneaen_Hydra> * Lerneaen_Hydra slaps SWPadnos with the trout *again*
[20:32:17] <robin_sz> 1.2+1.5 304
[20:32:29] <alex_joni> 304 ?
[20:32:34] <robin_sz> stainless
[20:32:40] <alex_joni> ah.. I see
[20:32:48] <alex_joni> that's about 5-6 kVa
[20:32:51] <alex_joni> kVA even
[20:33:27] <robin_sz> this is anlyu a small welder
[20:33:31] <robin_sz> 90KVA
[20:33:53] <alex_joni> a bit oversized :P
[20:34:28] <robin_sz> 12 cycles on 20% power seems to weld it
[20:34:44] <alex_joni> does it do ramps?
[20:35:26] <robin_sz> nah
[20:35:31] <SWPadnos> sorry to interject, but this is way too funny: http://media1.break.com/dnet/media/2006/10/oct26gallery62.jpg
[20:36:08] <robin_sz> it could do witha much better controller really
[20:36:18] <robin_sz> anyway .. the problem is the chiller
[20:36:44] <robin_sz> this is the bit I dont understand. chillers.
[20:36:45] <Lerneaen_Hydra> SWPadnos: mental images... go away...
[20:36:47] <cradek> SWPadnos: I don't buy it for a second...
[20:37:31] <alex_joni> robin_sz: what about it? they seem to be very stupid on spot welders
[20:37:41] <SWPadnos> heh
[20:37:47] <alex_joni> cradek: what? the deckchair?
[20:37:55] <alex_joni> * alex_joni wouldn't buy it either
[20:38:04] <SWPadnos> it's broken ;)
[20:38:07] <SWPadnos> and icky
[20:38:14] <alex_joni> a similar model :)
[20:38:45] <robin_sz> how come all chillers seem to have the same basic bits on them .. a compressor, a switch ting fed with one pipe from the circuit that presumably detects soem absolute pressure, another switch thing fed with two pipes, that does somehtitg with absolute and differential pressures
[20:38:46] <jepler> if {$::metric} {
[20:38:46] <jepler> set speed [expr {25.4 * $speed}]
[20:38:47] <jepler> }oops
[20:38:57] <robin_sz> ALL the ones I have have exactly the same units
[20:39:16] <robin_sz> but nowhere can I find an explanation of what the fsck they do
[20:39:34] <alex_joni> robin_sz: spot welder users are very cheap :)
[20:39:38] <Jymmm> * Jymmm has a 5 ton chiller for sale.... BYOC
[20:39:49] <alex_joni> I've seen people connecting 10 spot guns to the main water supply
[20:39:49] <robin_sz> 5 tons?
[20:39:54] <alex_joni> and just let it run through
[20:40:09] <robin_sz> what is 5 tons in kilowatts?
[20:40:21] <Jymmm> robin_sz you can have BOTH of them for $2000 USD
[20:40:47] <robin_sz> how do you convert tons to kw?
[20:40:55] <SWPadnos> nfc
[20:40:59] <alex_joni> units
[20:41:01] <cradek> haha americans
[20:41:02] <SWPadnos> I had wondered that myself, some time ago
[20:41:10] <robin_sz> my big chiller is 45kw ... draws 37A/phase of 3 phase at 415
[20:41:17] <CIA-8> 03jepler 07HEAD * 10emc2/share/axis/tcl/axis.tcl: make the linear jog speed slider change units with the rest of the display
[20:41:17] <CIA-8> 03jepler 07HEAD * 10emc2/src/emc/usr_intf/axis/scripts/axis.py: make the linear jog speed slider change units with the rest of the display
[20:41:18] <SWPadnos> or BTU, for that matter
[20:41:34] <robin_sz> BTU is some ancient craziness, best forgotten
[20:41:38] <Jymmm> BYOC == Bring Your Own Crane
[20:41:42] <SWPadnos> it is British
[20:41:47] <robin_sz> indeed.
[20:41:50] <robin_sz> but crazy
[20:42:20] <anonimasu> heh
[20:42:43] <alex_joni> and still widely used (BTU that is)
[20:42:52] <robin_sz> only for central heating boilers
[20:43:08] <anonimasu> btu?
[20:43:09] <alex_joni> and for AC's
[20:43:15] <alex_joni> british thermal units
[20:43:20] <anonimasu> ah hehe
[20:43:51] <robin_sz> anyway ... fscking chiller is not chilling .. 200 welds and the water is warm enough to take a bath in
[20:44:29] <robin_sz> maybe I'll just hook it up to the tap
[20:45:19] <robin_sz> I have 1600 welds to do, bored now.
[20:47:38] <Jymmm> Anyone have/use a dual cpu system?
[20:47:47] <robin_sz> I just wish I could find a decent explanation on the switch sensor wotsit things in these chillers?
[20:47:57] <robin_sz> Jymmm: several,
[20:48:24] <Jymmm> robin_sz ever find that your running an operation, but the cpu's never peak?
[20:48:33] <robin_sz> in 'top' just press 1 to see the activity on each CPU
[20:48:55] <robin_sz> mmm, its rare to see them maxxed out
[20:49:11] <SWPadnos> I have a dual cdual-core system
[20:49:24] <SWPadnos> and it's FRIGGIN FAST!!!
[20:49:46] <SWPadnos> ahem - sorry
[20:49:48] <Jymmm> I was importing 800MB of data, but the cpu's stayed around 55% and the memory stayed around 600MB out of 1GB, the hdd is a 15Krpm scsi
[20:49:59] <Jymmm> but the operation took like 12 minutes
[20:50:26] <robin_sz> Tasks: 288 total, 2 running, 284 sleeping, 0 stopped, 2 zombie
[20:50:26] <robin_sz> Cpu0 : 15.4% user, 2.9% system, 0.0% nice, 81.7% idle
[20:50:26] <robin_sz> Cpu1 : 1.0% user, 2.6% system, 0.0% nice, 96.4% idle
[20:50:26] <robin_sz> Cpu2 : 7.8% user, 0.7% system, 0.0% nice, 91.5% idle
[20:50:26] <robin_sz> Cpu3 : 61.8% user, 2.9% system, 0.0% nice, 35.3% idle
[20:50:26] <robin_sz> Mem: 1033308k total, 1020680k used, 12628k free, 66568k buffers
[20:50:28] <robin_sz> Swap: 1477940k total, 128504k used, 1349436k free, 576192k cached
[20:51:28] <SWPadnos> importing into what?
[20:51:44] <Jymmm> SWPadnos mysql db
[20:51:59] <SWPadnos> lots of BLOBs, or textual data?
[20:52:09] <robin_sz> probably disk bandwidth rather than CPU limited
[20:52:20] <Jymmm> all text UTF8
[20:52:50] <SWPadnos> for a database, I'd bet on seek time
[20:53:01] <robin_sz> true enough
[20:53:09] <Jymmm> hdd seek time?
[20:53:10] <SWPadnos> and data transfer, of course
[20:53:17] <robin_sz> uh huh
[20:53:21] <Jymmm> k
[20:53:34] <robin_sz> using ext3?
[20:53:37] <Jymmm> no onboard raid, so sol there
[20:53:38] <robin_sz> or ext2?
[20:53:42] <Jymmm> 3
[20:53:50] <SWPadnos> PCI system?
[20:54:00] <Jymmm> yeah
[20:54:04] <robin_sz> considered a battery backed ram card for the journal?
[20:54:25] <Jymmm> never heard of it
[20:54:36] <SWPadnos> expensive as hell though
[20:54:46] <robin_sz> nah, cheap now
[20:54:53] <robin_sz> sub $100
[20:54:55] <SWPadnos> you can also use noatime as a mount option, at least while doing the import
[20:55:00] <SWPadnos> oh 0didn't know that
[20:55:03] <SWPadnos> including RAM?
[20:55:08] <robin_sz> plus ram
[20:55:11] <SWPadnos> ok ;)
[20:55:18] <robin_sz> but you only need 256mb max
[20:55:26] <robin_sz> like $20
[20:55:33] <robin_sz> for a journal
[20:56:12] <robin_sz> they sell the cards to use as silicon disk drives, expect you to put about 5gb of ram on it ...
[20:56:50] <robin_sz> we just put a single 256mb brick on it to use as a ext3 journal
[20:57:24] <SWPadnos> interesting. how is the setup for that? (using a different device for the journal)
[20:58:06] <robin_sz> I foreget .. was a while ago we set it up
[20:59:35] <robin_sz> -j external-journal
[20:59:36] <robin_sz> Set the pathname where the external-journal for this filesystem
[20:59:36] <robin_sz> can be found.
[21:02:11] <robin_sz> man mke2fs has all the details
[21:02:30] <Jymmm> -----
[21:19:12] <Jymmm> Ok, name a WELL KNOWN landmark in the US that's within a 12 sq mile area that almost anyone in the world has heard of (Grand Canyon is is larger that 12 sq miles as example, No WTC or White House)
[21:19:33] <alex_joni> red rock something?
[21:19:37] <cradek> great wall of china!
[21:19:44] <alex_joni> not in the US yet
[21:19:45] <Lerneaen_Hydra> göteborg!
[21:19:47] <SWPadnos> <12 square miles?
[21:20:03] <SWPadnos> and not man-made, or anything?
[21:20:03] <Jymmm> SWPadnos read the example
[21:20:31] <SWPadnos> ok - <12 sq. mi. no individual buildings, or no man-made things? ...
[21:20:36] <alex_joni> golden gate bridge
[21:20:50] <alex_joni> oh.. no buildings?
[21:20:52] <robin_sz> niagra falls?
[21:20:53] <alex_joni> central park
[21:20:56] <SWPadnos> dunno - trying to find out
[21:21:01] <Jymmm> doens't matter what it is, but the grand caynony or Yosemite are both larger than 12 sq miles
[21:21:07] <alex_joni> central park
[21:21:24] <SWPadnos> the Las Vegas Strip
[21:21:26] <robin_sz> george bush?
[21:21:41] <SWPadnos> oh - the implication was that people should like it
[21:21:51] <Jymmm> robin_sz I said landmark, not dumbass
[21:21:54] <SWPadnos> at least that's what I thought
[21:21:59] <SWPadnos> the Alamo
[21:22:03] <alex_joni> nah
[21:22:14] <robin_sz> heh, you elected him, not me
[21:22:24] <SWPadnos> well, the Brooklyn Bridge would probably qualify
[21:22:27] <SWPadnos> no I didn't
[21:22:40] <Jymmm> If you live in Africa, and were going to visit the US for the first time, what would you be familure with and might want to see?
[21:22:45] <SWPadnos> watch your tongue, BritMan ;)
[21:22:59] <SWPadnos> clean water
[21:23:03] <Jymmm> lol
[21:23:12] <robin_sz> the immigration booth?
[21:23:28] <alex_joni> customs
[21:23:28] <SWPadnos> the National Mall
[21:23:32] <robin_sz> walmart?
[21:23:35] <SWPadnos> Smithsonian
[21:23:45] <robin_sz> wtf is the national mall?
[21:23:56] <Jymmm> what robin_sz said
[21:24:07] <SWPadnos> that's the big park that the Smithsonian, congress, and other stuff is near, in DC
[21:24:13] <SWPadnos> Mount Rushmore
[21:24:21] <A-L-P-H-A> hi folks.
[21:24:29] <A-L-P-H-A> what's up? and exciting now these days?
[21:24:33] <robin_sz> not heard of it
[21:24:39] <robin_sz> whats mt rushmore?
[21:24:45] <anonimasu> A-L-P-H-A: nothing really
[21:24:45] <alex_joni> robin_sz: secret facility
[21:24:46] <Jymmm> What about Disneyland or Statur of Liberty?
[21:24:54] <A-L-P-H-A> is that the stupid faces on a mountain?
[21:24:58] <SWPadnos> well, the statue of liberty would be up there
[21:24:59] <robin_sz> ahh, that
[21:25:12] <alex_joni> ahh.. not that one :)
[21:25:16] <SWPadnos> Ellis Island is <12 square miles
[21:25:27] <SWPadnos> Area 51
[21:25:27] <robin_sz> i went to NYC once .. didnt see the statue, somone said it was on an island somwhere
[21:25:35] <SWPadnos> in da river
[21:25:35] <Jymmm> SWPadnos I only know about it from watching L&O
[21:25:44] <SWPadnos> Liberty?
[21:25:50] <Jymmm> Ellis Island
[21:25:53] <robin_sz> nyc was a bit crap really
[21:25:54] <SWPadnos> ah
[21:25:54] <alex_joni> robin_sz: go by ship the next time
[21:26:18] <Jymmm> ok GGB looks to be the top so far... why I'll never know
[21:26:23] <robin_sz> the overall impression was dirty
[21:26:34] <alex_joni> ggb?
[21:26:41] <Jymmm> Golden Gate Bridge
[21:26:58] <robin_sz> is it big?
[21:27:02] <alex_joni> yay.. I said that
[21:27:12] <alex_joni> robin_sz: it doesn't need to be big
[21:27:16] <skunkworks1> largest ball of twine?
[21:27:23] <SWPadnos> NYC is like London. interesting for a while, but then it wears off
[21:27:23] <Jymmm> lol @ skunkworks
[21:27:28] <robin_sz> yeah
[21:27:29] <alex_joni> Jymmm: it was in awfull many films
[21:27:29] <SWPadnos> Minnesota
[21:27:36] <robin_sz> london sucks too
[21:27:38] <SWPadnos> Cranberry World ;)
[21:27:54] <robin_sz> one of my welders went to bangkok last week
[21:27:59] <robin_sz> for 8 days.
[21:28:05] <alex_joni> to buy a wife?
[21:28:05] <Jymmm> alex_joni But if you're visiting the US for the first time, is a bridge something you would really want to see?
[21:28:14] <robin_sz> poor chap, could harldy walk when he got back
[21:28:22] <alex_joni> Jymmm: not really, and it's on the wrong side of the US anyways
[21:28:54] <robin_sz> Jymmm: yeah .. a bridge would be nice... gives the prospect of a way out of the damn place ;)
[21:29:22] <Jymmm> robin_sz Ha! Damn thing has way too much rush hour traffic
[21:29:32] <SWPadnos> faster to swim
[21:29:47] <Jymmm> pretty much
[21:30:09] <SWPadnos> I guess the answer to your original question would really depend on the person(s) visiting
[21:30:32] <SWPadnos> Natural wonders, buildings, "attractions", entertainment ...
[21:30:55] <A-L-P-H-A> going to the shop. :D
[21:30:59] <A-L-P-H-A> time to play for the weekend.
[21:31:04] <SWPadnos> The Io needle on Maui is pretty cool
[21:31:05] <Jymmm> SWPadnos Well, it's more of someplace that ppl aroudn the world would be familure with. Like the only thing I could name in China is the GWOC, but it aint 12 sq miles =)
[21:31:17] <SWPadnos> hmmm
[21:31:20] <Jymmm> 1200 maybe =)
[21:31:35] <SWPadnos> 1500 miles long, but only ~20 feet wide
[21:31:39] <robin_sz> the only man-made structure visible to the naked eye from space
[21:31:43] <SWPadnos> so maybe it is <12 square miles ;)
[21:31:52] <Jymmm> SWPadnos Uh, no =)
[21:32:01] <Jymmm> (not formy needs that is )
[21:32:26] <robin_sz> * robin_sz has guessed what Jymm is planning
[21:32:49] <SWPadnos> the Microsoft campus
[21:32:58] <Jymmm> Like Australia, the only thing I can think of is the Opera House <12 sq mi, and the GBR > 12sq mi
[21:33:30] <robin_sz> you are plannling to release a chemical weapon, that has a coverage area of 12 sq miles, and are trying to work out where to release it to get the greatest number of foreing visitors in one hit, right?
[21:34:03] <SWPadnos> after luring them here with promises of seeing something they've heard of
[21:34:04] <Jymmm> No, just targeting a known landmark on a map where the scale is 12 sq mi
[21:34:21] <Jymmm> it's for a tutorial
[21:34:36] <alex_joni> how to kill the most imigrants in 10 easy steps
[21:34:46] <Jymmm> let them in America?
[21:34:50] <SWPadnos> Winooski, VT. it's only 1 square mile
[21:34:55] <Jymmm> lol
[21:34:58] <alex_joni> what's that?
[21:35:01] <Jymmm> SWPadnos and your home town?
[21:35:05] <SWPadnos> no way
[21:35:16] <SWPadnos> I leved there for a few years though
[21:35:18] <alex_joni> Jymmm: don't want that to be known
[21:35:19] <SWPadnos> lived, too
[21:35:26] <Jymmm> SWPadnos I got ya beat.... Timbucktoo Az, it's only 300 sq FEET
[21:35:37] <Jymmm> ok maybe 1000 Sq ft
[21:35:40] <alex_joni> I heard of timbucktoo :)
[21:35:42] <robin_sz> in england, we just send them out to collect chellfish at lowtide, and then wait for the tide to come in
[21:36:17] <alex_joni> tide as in _run_?
[21:36:41] <robin_sz> that was something like 40 illegal immigrants drowned on the same day out collecting shellfish .. sometime last year
[21:37:16] <ALPHA-EMC> me!
[21:37:18] <ALPHA-EMC> mememe!
[21:37:31] <robin_sz> nah, thwy saw you already
[21:37:38] <SWPadnos> yeah, and once is enough
[21:37:47] <Lerneaen_Hydra> ALPHA-EMC: O.o
[21:37:50] <robin_sz> this is great .. I have wireless networking again :)
[21:37:58] <Lerneaen_Hydra> ALPHA-EMC: so, what's happening?
[21:38:05] <ALPHA-EMC> robin_sz: ... do you have roaming VOIP yet?
[21:38:17] <ALPHA-EMC> Lerneaen_Hydra: ... about to calibrate my machine's backlash.
[21:38:18] <robin_sz> wireless voip?
[21:38:23] <ALPHA-EMC> robin_sz: yes.
[21:38:23] <Lerneaen_Hydra> ooh
[21:38:25] <Lerneaen_Hydra> nice
[21:38:33] <robin_sz> alex_joni, yes and no
[21:38:47] <robin_sz> ALPHA-EMC: yes and no
[21:38:47] <ALPHA-EMC> robin_sz: voip... wireless... so you can run asterisks to a mobile VOIP hands free phone.
[21:39:03] <robin_sz> I have that ... but not how you might suspect
[21:39:12] <ALPHA-EMC> robin_sz: ... quit stealing. ;)
[21:39:18] <ALPHA-EMC> okay... measuring time.
[21:39:25] <Lerneaen_Hydra> bah, 'night people
[21:39:31] <robin_sz> asterisk to Linksys SPA2102, dect phone
[21:39:41] <ALPHA-EMC> 1.6 ratio gear to a 0.1" worm... [so many gears... I think I'll direct drive it soon enough.
[21:39:52] <robin_sz> I have some Zyxel WiFi phones.
[21:40:00] <robin_sz> piece of crap
[21:40:04] <ALPHA-EMC> with a 10 ustep. hmm.
[21:40:29] <ALPHA-EMC> so that's 2000 pulses to get one rev outta the motor. need 8 revs to make 5 revs of the big guy.
[21:40:38] <robin_sz> the zyxel "prestige" wifi phones are very VERY crappy. really really bad
[21:41:05] <ALPHA-EMC> 2000 * 1.6 / .1 = 32000 pulses?
[21:41:14] <ALPHA-EMC> yeah, that's right.
[21:41:14] <robin_sz> the SIP->ATA, ATA->dect is a much better solution
[21:41:21] <ALPHA-EMC> right?
[21:41:38] <ALPHA-EMC> 2000pules * 1.6 gear ration... each turn of the worm is 0.100"
[21:42:00] <alex_joni> ALPHA-EMC: that's a bad word in romanian
[21:42:10] <robin_sz> pules?
[21:42:12] <alex_joni> similar to cock :)
[21:42:14] <alex_joni> yeah
[21:42:17] <ALPHA-EMC> pules?
[21:42:18] <ALPHA-EMC> hahaha
[21:42:19] <alex_joni> actually the singular
[21:42:27] <alex_joni> without the s
[21:42:28] <ALPHA-EMC> "pico" I head mean dick in spanish...
[21:42:38] <ALPHA-EMC> or latin... whatever
[21:42:41] <robin_sz> pipe in french
[21:42:45] <alex_joni> yeah, they seem to have small ones
[21:42:59] <ALPHA-EMC> haha... French... PIPE... hard steel shaft... not bad.
[21:43:31] <alex_joni> how does this look? http://www.robcon.ro/emc/emc2_user_manual_cover_v2.png
[21:43:43] <ALPHA-EMC> I set my base period now to 32000
[21:43:45] <ALPHA-EMC> eerk.
[21:43:50] <ALPHA-EMC> duron 700...
[21:44:04] <alex_joni> that's high ALPHA-EMC
[21:44:18] <ALPHA-EMC> well... I kind of need it for my Z axis.
[21:44:20] <robin_sz> -j external-journal
[21:44:20] <robin_sz> Set the pathname where the external-journal for this filesystem
[21:44:20] <robin_sz> can be found.
[21:44:25] <robin_sz> oops
[21:44:28] <ALPHA-EMC> unless I set my Z axis speeds to lower.
[21:44:32] <alex_joni> ALPHA-EMC: high, as in slow
[21:44:42] <alex_joni> I ran mine with 8000 :D
[21:44:44] <robin_sz> Heaven is a place where:
[21:44:45] <robin_sz> The lovers are Italian
[21:44:45] <robin_sz> The cooks are French
[21:44:45] <robin_sz> The mechanics are German
[21:44:45] <robin_sz> The police are English
[21:44:45] <robin_sz> The government is run by the Swiss
[21:44:47] <robin_sz> Hell is a place where: The lovers are Swiss The cooks are English The mechanics are French The police are German The government is run by the Italians
[21:44:55] <ALPHA-EMC> alex_joni: and the MHZ of that machine is??
[21:44:59] <alex_joni> 1200
[21:45:01] <ALPHA-EMC> is it a duron as well??
[21:45:05] <alex_joni> athlon
[21:45:09] <alex_joni> close though :)
[21:45:11] <ALPHA-EMC> this is not an athlon... it's a duron.
[21:45:17] <ALPHA-EMC> slower POS.
[21:45:22] <alex_joni> it should do 25000
[21:45:29] <alex_joni> at least
[21:45:57] <ALPHA-EMC> ohhh... oops... I set it to 32000 from 30000
[21:46:13] <alex_joni> that's not an increase in performance ;)
[21:47:03] <ALPHA-EMC> we should really allow that to be input as the inverse of a second.
[21:47:35] <alex_joni> * alex_joni sends ALPHA-EMC back to when you would specify it in seconds
[21:47:43] <alex_joni> try 0.000032
[21:47:53] <alex_joni> and keep track of 0'es
[21:47:57] <ALPHA-EMC> I've got it gonig at 25000
[21:48:07] <alex_joni> I suspect 20000 will be no problem too
[21:48:26] <alex_joni> at one point you'll notice it gets really sluggish (once you turn emc2 on)
[21:48:35] <alex_joni> then you need to back down a little
[21:48:48] <ALPHA-EMC> already sluggish... but bearable.
[21:51:17] <alex_joni> ok, then you found it :)
[21:51:25] <alex_joni> if you go too low it will lock up
[21:52:38] <alex_joni> * alex_joni ponders about going to sleep
[21:52:46] <alex_joni> need to wake up in about 6 hours :(
[21:52:53] <anonimasu> :(
[21:52:54] <skunkworks1> alex_joni: what time is it there?
[21:53:05] <alex_joni> close to 1am
[21:53:33] <skunkworks1> I must be getting tired - i read that as 'close to LAM'
[21:53:48] <alex_joni> close to lam
[21:54:01] <skunkworks1> I figured it out ;)
[21:56:45] <SWPadnos> roughly 01:00
[21:57:05] <SWPadnos> or zero-one-hundred hours :)
[21:57:41] <alex_joni> yeah, wait 24 hours then it'll be 25 hours later
[21:57:49] <SWPadnos> yep
[21:58:11] <alex_joni> finally going back to GMT+w
[21:58:13] <alex_joni> finally going back to GMT+2
[21:58:19] <SWPadnos> ugh
[21:58:50] <SWPadnos> does the whole world get screwed bu Bush's change to DST, or is it just us?
[21:58:50] <alex_joni> we're GMT+2+DST now
[21:58:57] <SWPadnos> s/bu/by/
[21:58:58] <alex_joni> most do :)
[21:59:08] <SWPadnos> what a prick
[21:59:11] <alex_joni> except some countries which already changed
[21:59:18] <alex_joni> and others that haven't yet
[21:59:40] <SWPadnos> I say let's just move 30 minutes in between and leave it alone
[21:59:44] <anonimasu> dst?
[21:59:49] <SWPadnos> daylight savings time
[21:59:53] <anonimasu> oh
[22:00:01] <anonimasu> the whole world gets screwed but not at the same time
[22:01:57] <ALPHA-EMC> a week apart or something
[22:02:01] <alex_joni> it's probably tiring to screw the whole world at the same time
[22:02:01] <SWPadnos> yeah, but Bush decided last year that sometime (I think next year), we'll be changing to winter hours on a different weekend than it's been done the last 100 years or so
[22:02:42] <SWPadnos> some energy usage drivel that's totally irrelevant in this age
[22:03:38] <ALPHA-EMC> SWPadnos: ... umm... DST was made up during one of the world wars.
[22:03:48] <anonimasu> gee
[22:03:52] <anonimasu> I wonder how they madeit before..
[22:04:13] <SWPadnos> time reckoning was standardized in the US in the late 1800's, I think
[22:05:05] <alex_joni> I just remembered.. if I ever go to NYC, I'll probably visit Ellis Island
[22:05:24] <ALPHA-EMC> remember to blow it up.
[22:05:24] <SWPadnos> ok - put into practicve in 1917 byt he Germans (WW 1)
[22:05:34] <alex_joni> have a great-grandmother and grandfather signed there :)
[22:05:45] <SWPadnos> first proposed by Ben Franklin in 1784 though
[22:05:47] <alex_joni> they came back though :/
[22:05:49] <SWPadnos> heh
[22:06:17] <ALPHA-EMC> WHAT the hell am I doing wrong?
[22:06:26] <ALPHA-EMC> G91
[22:06:26] <ALPHA-EMC> G00 X+0.05
[22:06:26] <ALPHA-EMC> G00 X-0.025
[22:06:26] <ALPHA-EMC> M00 ("0" the dial now)
[22:06:26] <ALPHA-EMC> G00 X-0.025
[22:06:27] <ALPHA-EMC> G00 X+0.025
[22:06:28] <SWPadnos> configuration?
[22:06:29] <ALPHA-EMC> M02 (READ backlash now)
[22:06:39] <ALPHA-EMC> I set read the dial... and it says 0.004"
[22:06:50] <ALPHA-EMC> I set the backlash to 0.004"... and it doesn't do dinkus.
[22:07:19] <ALPHA-EMC> I rerun the script, and I get 0.002" off now.
[22:07:23] <alex_joni> ALPHA-EMC: did you restart emc?
[22:07:30] <ALPHA-EMC> alex_joni: yup.
[22:07:39] <alex_joni> odd :(
[22:07:41] <ALPHA-EMC> I changed the backlash, save, exit emc, restart.
[22:07:50] <ALPHA-EMC> the SCREw cannot be that much off.
[22:08:01] <SWPadnos> where does backlash go? into TP or stepgen?
[22:08:15] <alex_joni> motion
[22:08:18] <ALPHA-EMC> I put it inthe stepper_inch.ini file.
[22:08:26] <alex_joni> SWPadnos: neither
[22:08:29] <ALPHA-EMC> I'll make the movements bigger.
[22:08:31] <alex_joni> it's before stepgen
[22:08:32] <SWPadnos> ok
[22:08:38] <alex_joni> after/parallel to TP
[22:10:48] <skunkworks1> I thought on stepper machines backlash didn't obay machine limits
[22:10:57] <alex_joni> it does now
[22:11:00] <alex_joni> mostly :)
[22:11:07] <skunkworks1> cool
[22:12:23] <ALPHA-EMC> larger movements. it's okay
[22:12:31] <ALPHA-EMC> 0.00625" urk
[22:13:01] <ALPHA-EMC> well... not reading the dial super super proper... but hey... it's a pretty good guess at that .00025 mark.
[22:13:15] <ALPHA-EMC> still kind large I think.
[22:14:40] <SWPadnos> .00025?
[22:14:49] <SWPadnos> that's not too large, I think
[22:15:33] <SWPadnos> you should make large movements to test. very small ones may not have enough motion to allow for the backlash comp to be fully done
[22:16:14] <SWPadnos> move X+1.000, then X-1.00, zero the indicator, then do the 1 inch moves again (like the 0.025 moves you had before)
[22:18:09] <ALPHA-EMC> no. it's going 0.00625" OFF!
[22:18:13] <ALPHA-EMC> that's the backlash.
[22:18:15] <ALPHA-EMC> :(
[22:18:18] <ALPHA-EMC> it's messed.
[22:18:30] <ALPHA-EMC> that's X.
[22:18:36] <ALPHA-EMC> Y is worse... 0.0084" or so
[22:19:06] <anonimasu> that's huge
[22:19:21] <ALPHA-EMC> Yup.
[22:19:29] <ALPHA-EMC> wth am I gonna do... I don't know how to fix that...
[22:19:50] <ALPHA-EMC> unless I put in another ballscrew with a springdisc washer
[22:20:06] <ALPHA-EMC> and I don't have room for that in my X axis.
[22:20:19] <anonimasu> arent your mill a benchtop?
[22:20:27] <ALPHA-EMC> I do have the nuts. just not the room underneith
[22:20:29] <ALPHA-EMC> yup
[22:20:35] <anonimasu> got a link/pic
[22:20:47] <ALPHA-EMC> give me a few minutes to round up photos then.
[22:20:52] <anonimasu> ok
[22:29:41] <A-L-P-H-A> sorry, got sidetracked with emails from clients.
[22:30:25] <anonimasu> ok
[22:38:55] <A-L-P-H-A> http://lloydleung.com/gallery/Mill_Related/2006-10-27_Mill_Mounts/ there should be 7 photos in total once they're all uploaded
[22:39:36] <anonimasu> ok
[22:39:38] <A-L-P-H-A> yeah they're all uploaded
[22:40:17] <anonimasu> it's small :/
[22:40:30] <anonimasu> I thought it was about the same size as my tabletop
[22:40:31] <A-L-P-H-A> dude... I bought a whole shop for like $4K CDN...
[22:40:35] <A-L-P-H-A> what can I complain about?
[22:40:43] <anonimasu> err benchtop :)
[22:40:46] <anonimasu> hehe
[22:41:16] <anonimasu> ^_^
[22:41:28] <anonimasu> other then that it's a hell to mount ballscrews there :)
[22:41:37] <anonimasu> correction "preloaded ballnuts"
[22:41:39] <A-L-P-H-A> whole shop {lathe, mill, laptops, bandsaw, two bench grinders, surface block, there's a shit load of cutters, and stock, drill press, air compressor, shitty stepper controller}
[22:41:52] <A-L-P-H-A> yeah.
[22:42:00] <A-L-P-H-A> ballscrews... I don't think I can get to fit in there at all.
[22:42:31] <A-L-P-H-A> err preloaded ballnuts
[22:42:38] <A-L-P-H-A> damn you for screwing me up.
[22:42:54] <A-L-P-H-A> other than the bad backlash... it runs great!
[22:43:55] <A-L-P-H-A> if I do this... I'm going to build a whole need table for the mill... out of 2" box tubing or something beefy.
[22:44:06] <A-L-P-H-A> I'll check out my metal supplier tomorrow, and see what I can get cheap.
[22:45:49] <anonimasu> 46hm ok
[22:46:53] <A-L-P-H-A> hmm... welding fun this weekend?
[22:47:21] <anonimasu> :)
[22:55:30] <A-L-P-H-A> I'm like debating on how to make my stand now.
[22:58:37] <alex_joni> * alex_joni is off to bed
[22:58:40] <alex_joni> good night all
[22:58:59] <A-L-P-H-A> later alex_joni
