[00:36:56] <jmk_dinner> jmk_dinner is now known as jmkasunich
[00:49:44] <Phydbleep> Igor! It's a LATHE!
[00:50:00] <Phydbleep> Mwahahaha! :)
[01:51:11] <Phydbleep> Wow.. The compound and crossfeed on this thing moves like glass.. Not bad for a machine built in '47. :)
[01:58:00] <Phydbleep> And the ways are just as smooth. :)
[01:59:02] <A-L-P-H-A> it's called quality iron
[02:00:10] <Phydbleep> And good care/storage for 99% of it's life.
[02:01:49] <Phydbleep> It only got wet/weathered in the last 6 months when they moved it to storage in a leaky garage..
[02:02:29] <A-L-P-H-A> shibbs.
[02:02:53] <Phydbleep> * Phydbleep goes back to scraping dust, grease and dead spiders out of it.
[03:35:28] <Phydbleep> Everything works better when you scrape out the fossilized cosmoline. :)
[04:45:22] <CIA-4> 03jmkasunich 07kbuild-0-1 * 10emc2/src/emc/ (8 files in 4 dirs): merged a fix from the trunk
[06:23:43] <A-L-P-H-A> had to look up cosmoline.
[06:25:19] <Phydbleep> WW-II surplus gun/metal preservative.
[06:25:29] <A-L-P-H-A> I see.
[06:25:40] <A-L-P-H-A> I need to figure out how much material my mill can remove...
[06:25:52] <A-L-P-H-A> feed rate, doc, rpm, and stuff.
[06:52:10] <asdfqwega> Hm...here's something annoying
[06:52:19] <A-L-P-H-A> what?
[06:52:29] <asdfqwega> I want to use Axis for a friend of mine
[06:52:46] <asdfqwega> The job is doing inlays in wood
[06:53:01] <asdfqwega> Max width = 0.500"
[06:53:16] <A-L-P-H-A> height? or width??
[06:53:22] <asdfqwega> Working with a 0.313" dia cutter
[06:53:36] <asdfqwega> So, things are small
[06:53:51] <asdfqwega> Now, the machine needs to run at 18 IPM
[06:54:43] <asdfqwega> Now, when I choose to run Axis with these programs, the update interval makes a mess of the live plot
[06:55:26] <asdfqwega> I know my box may be a bit slow - 600 MHz Duron with a GeForce2 MX card
[06:56:42] <asdfqwega> Grrrr...Am I going to have to get a > 1 GHz CPU to make Axis run better?
[06:58:08] <asdfqwega> I've tried changing the .ini file parameters for polling intervals....no dice.
[07:00:56] <nevyn> it can probably be tweaked...
[07:01:12] <nevyn> does axis require 3d acceleration?
[07:01:47] <asdfqwega> I don't know...I thought it did
[07:02:20] <asdfqwega> I can't remember offhand how to check if it is
[07:02:23] <nevyn> did you configure 3d acceleration?
[07:02:39] <nevyn> does the nvidia binary driver work with adeos kernels?
[07:03:13] <asdfqwega> Yes, it does...I get the Nvidia splash screen when X starts
[07:03:46] <alex_joni> asdfqwega: how about using mini?
[07:04:01] <alex_joni> does have a backplot .. :)
[07:04:12] <alex_joni> I know it's not exactly Axis..
[07:05:19] <A-L-P-H-A> <shrug>
[07:05:27] <A-L-P-H-A> all this is beyond my knowledge right now.
[07:05:45] <A-L-P-H-A> damn, hungry... maybe I'll make some sushi.
[07:05:45] <A-L-P-H-A> Time: 03:05:38 -0500 GMT, Windows XP Professional, Service Pack 2 (5.1 - 2600), AMD XP 2800+ running at (1-AMD , 2123MHz, 512KB (100% Load)), DDR400 RAM Usage: 821/1024MB (80.18%), C: 43.67gb of 75.42gb free, D: 0gb of 0gb free, N: 27.91gb of 372.62gb free, Current Uptime: 2days 4hrs 47mins 54secs, Record Uptime: 3wks 12hrs 48mins 50secs, 3 Samsung 19" flat monitors (1 Trinitron, 2 CRT).
[07:05:59] <alex_joni> sushi is great
[07:06:23] <asdfqwega> My main goal is work on a setup that is easily visible, and shows a preview of the program
[07:06:36] <asdfqwega> sushi, the food?
[07:06:53] <asdfqwega> or is that a command line tool?
[07:06:54] <A-L-P-H-A> bbiab
[07:06:56] <alex_joni> Time: 10:05:51 +0200 GMT, Windows XP Home Edition, Service Pack 2 (5.1 - 2600), Intel Centrino 1400 running at (1-Intel , 599MHz, 0KB (0% Load)), DDR400 RAM Usage: 339/503MB (67.40%), C: 3.1gb of 37.25gb free, Current Uptime: 1wk 6days 21hrs 11mins 25secs, Record Uptime: 3wks 9hrs 30mins 56secs, 15'' TFT.
[07:07:50] <alex_joni> morning an0n
[07:08:10] <anonimasu> good morning
[07:10:51] <anonimasu> emc2 compile time
[07:11:59] <alex_joni> morning an0n
[07:12:06] <alex_joni> on 2.4 ?
[07:12:20] <anonimasu> yeah
[07:12:28] <alex_joni> should work like a charm
[07:12:53] <anonimasu> * anonimasu hopes it does
[07:13:41] <anonimasu> :)
[07:24:40] <anonimasu> hm emc2 ferrors on rapids
[07:24:51] <alex_joni> how rapids?
[07:25:25] <anonimasu> 1200mm/min
[07:25:44] <alex_joni> hmm.. dunno ;)
[07:25:54] <alex_joni> but at least it builds :D
[07:25:55] <alex_joni> and runs
[07:25:56] <alex_joni> =))
[07:26:07] <anonimasu> heh
[07:26:19] <anonimasu> always somthing
[07:26:22] <alex_joni> yeah
[07:26:34] <alex_joni> try reducing your max vel
[07:26:49] <alex_joni> I think pulse output doesn't keep up at those speeds
[07:27:59] <anonimasu> works now I just increased min ferror
[07:28:07] <alex_joni> ahh.. ok
[07:28:27] <anonimasu> I long for a vital.. so I can have insane speeds ;)
[07:28:32] <anonimasu> or well insane for my machine
[07:29:54] <anonimasu> I like emc2..
[07:30:03] <alex_joni> heh
[07:30:06] <alex_joni> glad you do
[07:30:14] <anonimasu> it seems more tidy then emc1
[07:31:25] <anonimasu> atleast codewise..
[07:31:39] <nevyn> that was one of the aims.
[07:31:57] <alex_joni> what nevyn said
[07:32:04] <anonimasu> * anonimasu nods
[07:32:26] <anonimasu> maybe I should really take my time and play with NML
[07:32:35] <nevyn> alex_joni: you've gotten further than me if it builds.
[07:32:56] <alex_joni> nevyn: it builds now on 2.6
[07:33:08] <alex_joni> but it's not fully workable yet
[07:33:08] <nevyn> so.. when I was at lca
[07:33:16] <alex_joni> lca?
[07:33:27] <nevyn> paul mckenny was talking about his recent work on PREMPT_RT
[07:33:31] <nevyn> linux.conf.au
[07:33:43] <Phydbleep> asdfqwega: You around?
[07:33:45] <nevyn> which is a way to do hard realtime in the kernel.
[07:33:59] <alex_joni> hmm.. that sounds interesting
[07:34:14] <alex_joni> but depends on the definition of HRT
[07:34:29] <nevyn> deterministic scheduling and latency
[07:34:33] <alex_joni> in my opinion hard realtime is only if everything else is switched off
[07:34:39] <alex_joni> including interrupts & such
[07:34:42] <anonimasu> * anonimasu nods
[07:34:50] <nevyn> basically this allows userspace code to run like it's an interupt handler.
[07:34:52] <anonimasu> alex_joni: agreed, like on a microcontroller or such..
[07:34:59] <Phydbleep> * Phydbleep has finished scraping cosmoline and de-gropping a lathe. :)
[07:35:04] <alex_joni> what's done under linux is .. kinda hard realtime (but not fully hard)
[07:35:06] <nevyn> so interupts preempt etc are all off..
[07:35:12] <alex_joni> more between soft & hard
[07:35:19] <anonimasu> I guess you should just run your RT tasks, on a dedicated machine
[07:35:23] <alex_joni> heh
[07:35:28] <anonimasu> and your userspace tasks on another one..
[07:35:29] <nevyn> posixrt is useless..
[07:35:31] <alex_joni> how about communication?
[07:35:40] <alex_joni> an0n: only polling
[07:35:47] <Phydbleep> anonimasu: That's why I use twm on my bdi.
[07:35:50] <alex_joni> that would be a pita to synch 2 machines
[07:36:10] <anonimasu> kind of like what we do with X today..
[07:36:13] <nevyn> alex_joni: this is new...
[07:36:22] <alex_joni> nevyn: tell me more
[07:36:22] <anonimasu> but well, without X on the box running the motion part
[07:36:24] <anonimasu> :)
[07:37:00] <nevyn> alex_joni: basically it's a way to have a userspace application running with the same privilages as an irq handler.
[07:37:58] <nevyn> so you'd have a realtime blob that provided bits of rtapi functionality that was just a app running as root.
[07:38:30] <alex_joni> sounds like the way RTAI is doing it
[07:38:46] <nevyn> it sortof is.. but sortof isn't
[07:38:57] <alex_joni> * alex_joni has to read more about it
[07:43:10] <A-L-P-H-A> instead of sushi. I made 2x(english muffin + egg + 2 strips of bacon + slice of cheese).
[07:43:19] <A-L-P-H-A> I feel full.
[07:43:21] <anonimasu> hm, peltiers are cool
[07:43:22] <anonimasu> :)
[07:43:32] <A-L-P-H-A> anonimasu, cooling your computer?
[07:44:03] <anonimasu> nope, just looked at some papers regarding them
[07:44:13] <Phydbleep> A-L-P-H-A: You forgot the spam. :)
[07:44:20] <A-L-P-H-A> bacon!
[07:44:28] <anonimasu> I was looking after piezoelectric sensors..
[07:44:29] <A-L-P-H-A> spam = evil... be it in can or electronic form
[07:44:44] <A-L-P-H-A> I think I have some back bacon in the freezer.
[07:44:48] <A-L-P-H-A> but that'd involve effort.
[07:44:52] <anonimasu> delta max at 73c
[07:44:53] <anonimasu> heh
[07:45:02] <anonimasu> now that's what I call cool..
[07:45:04] <A-L-P-H-A> hmm...
[07:45:16] <A-L-P-H-A> anonimasu, what about from like zero... what's the delta then!
[07:45:16] <anonimasu> stack a couple of peltiers to a X kg of alu/cu heatsink
[07:45:24] <A-L-P-H-A> I wanna make liquid nitrogen.
[07:45:26] <anonimasu> -73
[07:45:35] <anonimasu> A-L-P-H-A: but I dont think that'd work in real life..
[07:45:44] <anonimasu> A-L-P-H-A: that's probably absolute max ratings..
[07:45:47] <A-L-P-H-A> anonimasu, I know... I was gonna say.
[07:46:02] <A-L-P-H-A> I can see like something like 200oC, to like 127oC.
[07:46:08] <anonimasu> watercooling + peltier heat exchanger..
[07:46:14] <A-L-P-H-A> or whatever it's optimal heat removal is.
[07:46:31] <A-L-P-H-A> anonimasu, radiator... more economical in electrical costs.
[07:46:48] <A-L-P-H-A> I enjoy passive cooling, as I enjoy quiet.
[07:47:00] <anonimasu> max cooling effect is 57.8w of thoose peltiers I was looking at
[07:47:23] <A-L-P-H-A> what's the energy costs? 57.8w?
[07:47:36] <anonimasu> no idea, but that's the max
[07:47:48] <A-L-P-H-A> that's like half the energy for a light bulb...
[07:47:53] <anonimasu> 16v 6a
[07:47:54] <A-L-P-H-A> and I don't call that energy efficient.
[07:48:19] <anonimasu> as long as it's silent
[07:48:19] <anonimasu> ;)
[07:48:25] <Phydbleep> Oy vey, thats gonna be a lot of waste heat.
[07:48:27] <A-L-P-H-A> yeah.
[07:48:51] <A-L-P-H-A> but the heat's gotta go somewhere, it's just sucking heat from one side and passing it to the other side.
[07:49:03] <A-L-P-H-A> but ADDs even more heat on the other side in the process.
[07:49:17] <anonimasu> yep
[07:50:26] <anonimasu> ah found the sensors I was looking for
[07:52:13] <Phydbleep> Thermal differentials with the stacks will be an inverse log curve.
[07:53:47] <A-L-P-H-A> can that work? like stack peltier one on top of each other to increase the cooling?
[07:54:22] <Phydbleep> Yeah, But it hits critical mass and melts down.
[07:55:29] <anonimasu> Phydbleep: depends on what you exchange heat to..
[07:55:45] <alex_joni> exchange it for $$
[07:56:22] <anonimasu> peltier > pipe > house
[07:56:38] <Phydbleep> The cells can only move so much heat and the thermal waste will cook a 12 pack unles you're heating LN2 to start with.
[07:57:43] <Phydbleep> 12 stack that is.
[07:58:00] <anonimasu> :)
[08:01:10] <anonimasu> hm I should tweak the accel on emc2 in a bit..
[08:01:24] <anonimasu> the parts take 40 minutes instead of 4
[08:01:55] <A-L-P-H-A> heh
[08:14:41] <Phydbleep> * Phydbleep would settle for a complex part taking 3-4 hours.
[08:15:34] <Phydbleep> Load the program, Set the safeties and lock the door.. Wake me when it's done. :)
[08:15:51] <A-L-P-HA2> what were the last lines after my last message?
[08:15:56] <A-L-P-HA2> logger_aj, bookmark
[08:15:56] <A-L-P-HA2> See http://193.226.12.129/irc/irc.freenode.net:6667/emc/2005-05-09#T08-15-56
[08:15:59] <anonimasu> Phydbleep: that's scary
[08:16:12] <anonimasu> Phydbleep: this is a simple plastic part
[08:16:29] <Phydbleep> * Phydbleep is talking 0.050 cuts in Al.
[08:16:41] <A-L-P-HA2> Phydbleep, I have this... for production runs, I use my relays.
[08:16:44] <anonimasu> mm?
[08:16:51] <A-L-P-HA2> inches
[08:17:02] <anonimasu> 1.27mm
[08:17:03] <anonimasu> hm..
[08:17:07] <A-L-P-HA2> Phydbleep, what's the HP on the motor?
[08:17:11] <anonimasu> I take 4mm cuts :)
[08:17:19] <Phydbleep> 1/4" endmill and a part that looks like a 1" deep binary tree.
[08:17:35] <A-L-P-HA2> Phydbleep. photos!
[08:17:39] <anonimasu> yeah
[08:17:49] <A-L-P-HA2> what's the RPM on that endmill?
[08:18:08] <A-L-P-HA2> see... how do you guys calculate the RPM and feedrate of stuff?
[08:18:11] <A-L-P-HA2> it's like confusing me.
[08:18:22] <A-L-P-HA2> I'm not experienced with milling, but am with lathe work.
[08:18:50] <A-L-P-HA2> A-L-P-HA2 is now known as A-L-P-H-A_laptop
[08:19:01] <anonimasu> what unit is the accel in the config ?
[08:19:03] <anonimasu> mm/s
[08:19:45] <A-L-P-H-A_laptop> anonimasu, how do you calculate rpm/feedrate/doc?
[08:19:53] <anonimasu> I usually calc it in visualmill..
[08:19:56] <anonimasu> because it's easy..
[08:20:09] <anonimasu> when I mill this plastic I dont care..
[08:20:16] <A-L-P-H-A_laptop> plastic is like cutting air.
[08:20:21] <anonimasu> I can take 10mm cuts with a 4mm endmill..
[08:20:23] <anonimasu> yeah
[08:20:26] <A-L-P-H-A_laptop> I'm talking harder materials, like al, or steel.
[08:20:55] <anonimasu> hold on a bit..
[08:21:23] <A-L-P-H-A_laptop> I'm talking like plunge rates, finishing, roughing (amount of overlap), etc.
[08:21:36] <A-L-P-H-A_laptop> slotting, surfacing, etc.
[08:22:17] <anonimasu> yeah
[08:22:31] <anonimasu> I usually use the calc in visualmill.. and I cant remember how you calc it by hand
[08:22:49] <A-L-P-H-A_laptop> hmm, I'll have to play with visualmill. I'm currently using mastercam.
[08:23:01] <A-L-P-H-A_laptop> and I can get the toolpaths done, but I really don't think the speeds are correct.
[08:23:10] <anonimasu> visualmill is affordable ;)
[08:23:21] <A-L-P-H-A_laptop> $1000 USD = visualmill.
[08:23:31] <anonimasu> yeah affordable.
[08:23:36] <A-L-P-H-A_laptop> I have _access_ to both.
[08:23:44] <anonimasu> http://www.unionbutterfield.com/tech/sc/milling.asp
[08:23:52] <anonimasu> :)
[08:23:57] <alex_joni> * alex_joni goes to do some work
[08:23:59] <alex_joni> bye guys ;)
[08:24:00] <anonimasu> is there a mastercam post that works with emc?
[08:24:02] <A-L-P-H-A_laptop> later
[08:24:07] <alex_joni> yup
[08:24:12] <anonimasu> A-L-P-H-A: you have the calcs there
[08:24:19] <anonimasu> what's the name of it?
[08:24:52] <anonimasu> Ft x T x RPM
[08:25:00] <anonimasu> Ft = feed per tooth
[08:25:13] <anonimasu> T = tooths
[08:25:13] <A-L-P-H-A_laptop> that's IT?
[08:25:16] <anonimasu> yeah
[08:25:48] <Phydbleep> 10k rpm on the spindle
[08:25:49] <anonimasu> 0.05 * 3 * 3000 = 450mm/min
[08:26:00] <Phydbleep> * Phydbleep is looking for a pick of the part.
[08:26:09] <Phydbleep> s/pick/pic
[08:26:13] <anonimasu> 0.05 * 3 * 10000 = 1500mm/min
[08:26:37] <anonimasu> ;)
[08:26:57] <Phydbleep> http://www.tfcbooks.com/images/patents/valve1a.gif
[08:27:01] <A-L-P-H-A_laptop> I can't go that fast.
[08:27:11] <anonimasu> A-L-P-H-A: slow down your speed then..
[08:27:19] <anonimasu> until you get the chipload you want..
[08:27:47] <A-L-P-H-A_laptop> what kinda of chipload do I need/want?
[08:27:49] <anonimasu> otherwise it's dust making
[08:27:56] <anonimasu> I usually go for 0.07 in alu
[08:27:56] <Phydbleep> The thing at the top is what I want to make.
[08:28:06] <A-L-P-H-A_laptop> 0.07mm? or inches?
[08:28:08] <anonimasu> mm
[08:28:11] <A-L-P-H-A_laptop> oh.
[08:29:05] <A-L-P-H-A_laptop> anonimasu, what's the HP on that?
[08:29:05] <A-L-P-H-A_laptop> motor?
[08:29:05] <A-L-P-H-A_laptop> I'm only I think 1hp.
[08:29:05] <anonimasu> 2hp one
[08:29:05] <anonimasu> somwhere around 3000rpm
[08:29:05] <anonimasu> but I think I have a bit more..
[08:29:37] <A-L-P-H-A_laptop> I'm like 2560rpm. or something slow like that.
[08:29:37] <anonimasu> since I got the VFD cranked up to 200% torque..
[08:29:37] <anonimasu> overdriving
[08:30:41] <A-L-P-H-A_laptop> damn it, I'd really like to crack up the rpm + power of my motor...
[08:30:41] <A-L-P-H-A_laptop> Phydbleep, what's the HP/rpm of those threadmill motors?
[08:30:41] <anonimasu> A-L-P-H-A: vfd's are good/cheap
[08:30:41] <anonimasu> I am just waiting for my motor to die so I can get one with more hp..
[08:30:53] <anonimasu> http://www.maintenanceresources.com/referencelibrary/ezine/nurbs.htm
[08:30:55] <anonimasu> neat
[08:31:54] <anonimasu> but well I might build a small highspeed spindle for milling alu
[08:31:58] <A-L-P-H-A_laptop> now that's cool.
[08:32:07] <Phydbleep> I've got 1.5hp @ 4.5k rpm
[08:32:24] <A-L-P-H-A_laptop> Phydbleep. 1:1 gearing?
[08:32:30] <anonimasu> * anonimasu wishes he had that
[08:32:45] <Phydbleep> That's at the shaft.
[08:33:10] <Phydbleep> No gearing.. I was going to go 1:2.2 got get 10k
[08:33:56] <A-L-P-H-A_laptop> my mill sucks ass for that... it's a bench top mill, not a highspeed machining centre.
[08:34:08] <Phydbleep> s/got/to
[08:34:10] <A-L-P-H-A_laptop> and I should be happy with what I got. though I'd like something better.
[08:34:17] <anonimasu> chiploads seems to be about 0.15 in commercial apps..
[08:34:43] <Phydbleep> * Phydbleep is building the whole SOB anyway....
[08:34:48] <A-L-P-H-A_laptop> anonimasu, that's PER tooth?
[08:34:55] <anonimasu> yeah..
[08:35:02] <A-L-P-H-A_laptop> yikes. heh
[08:35:22] <A-L-P-H-A_laptop> anonimasu, what about how deep I go?
[08:35:32] <anonimasu> A-L-P-H-A: depth = dia
[08:35:32] <A-L-P-H-A_laptop> like how much material could I remove with a 1hp motor?
[08:35:59] <A-L-P-H-A_laptop> anonimasu, so like, a 12mm endmill, going 12mill deep of material?
[08:36:00] <anonimasu> but I usually go for 50% since I dont like the plunging
[08:36:31] <A-L-P-H-A_laptop> anonimasu, where do I set that up in visual mill, the depth of cut? And Ican't seem to get visualmill to spit out working gcode.
[08:36:40] <Phydbleep> I was going to feed the Z at a constant 0.050" per iteration.
[08:36:45] <A-L-P-H-A_laptop> like, everyhthing is only on 1 Z level depth.
[08:37:04] <anonimasu> hm, add finish passes
[08:37:14] <anonimasu> and roughing passes when you create the toolpath..
[08:37:23] <A-L-P-H-A_laptop> anonimasu, that was roughing...
[08:37:29] <A-L-P-H-A_laptop> I never made a finishing pass.
[08:37:31] <anonimasu> I can help you out with it later tonight
[08:37:35] <anonimasu> need to work a bit
[08:37:47] <A-L-P-H-A_laptop> cause when I tried to test the output, everything was on one level... like it never cut past the first one.
[08:37:54] <A-L-P-H-A_laptop> anonimasu, that'd be cool, thanks.
[08:38:04] <anonimasu> i THINK you can do DEPTH=DIA but well, dont take my word for it take it easy ;)
[08:38:22] <anonimasu> my plunges was at 250mm/min in alu..
[08:38:26] <anonimasu> 5mm ones..
[08:38:35] <anonimasu> without helical entry
[08:38:46] <A-L-P-H-A_laptop> nice.
[08:39:09] <anonimasu> the spindle moved.. since I had some screws that was loose :)
[08:39:10] <Phydbleep> Helical entry == 1 big chip?
[08:39:21] <anonimasu> nope.. ramped x y z
[08:39:21] <A-L-P-H-A_laptop> Phydbleep, no.
[08:39:24] <anonimasu> in a spiral..
[08:39:41] <anonimasu> cutting your way down
[08:39:44] <A-L-P-H-A_laptop> used in high speed machining, to go down in a part to pocket and such
[08:39:47] <anonimasu> very smooth way to enter a piece..
[08:39:57] <Phydbleep> Ah, The it dug a nice screwthread syndrome.
[08:40:06] <anonimasu> I love doing holes in the plastic that way
[08:40:08] <anonimasu> also
[08:40:15] <anonimasu> it takes a couple of secs per hole :)
[08:40:49] <A-L-P-H-A_laptop> hahahahah... someone on ebay is selling EMC BDI cds, for like $7.
[08:42:48] <anonimasu> hm.. maybe I should increase MAX ACCEL globally
[08:43:08] <anonimasu> lol
[08:43:09] <anonimasu> how stupid
[08:43:33] <anonimasu> the helical boring stuff dmess had was scary
[08:45:05] <anonimasu> :D
[08:45:54] <A-L-P-H-A_laptop> what'd dmess do?
[08:46:01] <anonimasu> he gave me some papers on helical boring
[08:46:09] <anonimasu> you have a tool and a spindle with a encoder..
[08:46:23] <anonimasu> you calulate the angle of the edge..
[08:46:31] <anonimasu> and turn parts on the mill..
[08:46:33] <anonimasu> ;)
[08:46:51] <anonimasu> requires insane machine speeds
[08:46:55] <A-L-P-H-A_laptop> heh
[08:47:05] <anonimasu> very very cool
[08:47:09] <A-L-P-H-A_laptop> I've got a lathe... boring is done with that... or on the mill, my boring head.
[08:48:08] <A-L-P-H-A_laptop> Phydbleep, how did you go and ask those excercise places?
[08:48:29] <A-L-P-H-A_laptop> "hello, do you happen to have any dead treadmills that you guys are going to toss?"
[08:49:13] <Phydbleep> Pretty much.. You want to talk to the service dept more than likely...
[08:49:34] <Phydbleep> And If they come up with one take them a 12 pack of beer. :)
[08:49:38] <A-L-P-H-A_laptop> are you talking manufacturers? or excercise equipement sale places?
[08:50:02] <anonimasu> well I guess it's time to try my mill for real..
[08:50:10] <A-L-P-H-A_laptop> anonimasu... photos!
[08:50:28] <anonimasu> nope
[08:50:30] <anonimasu> :)
[08:50:33] <A-L-P-H-A_laptop> why not?
[08:50:33] <A-L-P-H-A_laptop> :P
[08:50:35] <anonimasu> maybe later
[08:50:43] <A-L-P-H-A_laptop> www.lloydleung.com/gallery is some of my crap.
[08:50:49] <Phydbleep> Dealers... Anywhere they sell them to health clubs.. Call a couple of the health clubs and see who sold them theirs.
[08:50:52] <anonimasu> I'll be cranking out another prototype tonight....
[08:51:08] <anonimasu> I can take pics while I mill it :)
[08:51:15] <A-L-P-H-A_laptop> anonimasu, sweet.
[08:51:19] <A-L-P-H-A_laptop> Phydbleep, good idea.
[08:51:24] <A-L-P-H-A_laptop> I want a motor!
[08:51:26] <Phydbleep> anonimasu: Did you see the pic of what I want to mill?
[08:51:30] <anonimasu> yeah
[08:51:48] <A-L-P-H-A_laptop> like your motor would be awesome for my mill... I'd just make a new bracket, and a new pulley
[08:51:57] <anonimasu> mine?
[08:51:58] <anonimasu> haha
[08:52:00] <anonimasu> it's large :)
[08:52:03] <anonimasu> 3phase
[08:52:26] <A-L-P-H-A_laptop> no, Phydbleep's 1.5hp 4.5Krpm motor
[08:52:28] <Phydbleep> Hehehe.. .Mine is 130V and screams.
[08:52:35] <anonimasu> 340v ;)
[08:52:51] <anonimasu> I wish for a better mill someday
[08:53:12] <Phydbleep> ROFL.. I think hte neighbors would bitch if I tried that.. I'd need a
[08:53:19] <anonimasu> lol
[08:53:20] <anonimasu> heh
[08:53:21] <anonimasu> brb
[08:53:24] <Phydbleep> BIG diesel gen-set.
[08:53:28] <anonimasu> need to try this out
[08:54:06] <A-L-P-H-A_laptop> 2.0hp motor, @ 130VDC. hmm............ hmm.......................
[08:54:11] <A-L-P-H-A_laptop> 15.3amps.
[08:54:22] <A-L-P-H-A_laptop> hmmmmmmmmmmmmmmmmmmmmmmmmmmmm. $99USD
[08:55:54] <Phydbleep> What's it look like? is it pmdc? Most important.. Is it SEALED?
[08:56:28] <Phydbleep> chips will eat a dc drive unit quickly.
[08:56:50] <A-L-P-H-A_laptop> it's on the back of the mill... chips are not likely to get up around there.
[08:56:56] <A-L-P-H-A_laptop> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=15280&item=7137479689&rd=1&ssPageName=WD1V
[09:00:28] <Phydbleep> That doesn't look sealed.
[09:01:55] <A-L-P-H-A_laptop> how come treadmill motors are so much smaller looking than my mill motor?
[09:02:06] <Phydbleep> That also looks like a 3/4hp continous duty motor.
[09:02:17] <A-L-P-H-A_laptop> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=15280&item=7154837627&rd=1&ssPageName=WDVW
[09:02:27] <A-L-P-H-A_laptop> that one is open
[09:02:40] <Phydbleep> 'Treadmill' duty and pmdc.
[09:07:11] <A-L-P-H-A_laptop> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=26226&item=7513744319&rd=1 ? wth.... 10 minute duty cycle?
[09:07:38] <anonimasu> emc2 rocks.
[09:08:24] <anonimasu> * anonimasu is happy
[09:08:34] <anonimasu> it worked just got the Z accel and velocity left to set up..
[09:08:43] <anonimasu> runs happily at 1000mm/min without trouble..
[09:08:56] <anonimasu> although that's still slow ;)
[09:10:18] <A-L-P-H-A_laptop> mine goes at like 2000mm/min
[09:10:19] <A-L-P-H-A_laptop> :D
[09:10:23] <A-L-P-H-A_laptop> ballscrews are good
[09:11:27] <A-L-P-H-A_laptop> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=26226&item=7514332205&rd=1 <-- nice
[09:12:39] <Phydbleep> That Leeson is a jumper-pump motor
[09:12:56] <Phydbleep> They use those in the hopping lowriders.
[09:13:50] <Phydbleep> 10 minutes is about the length of time they compete..
[09:15:24] <A-L-P-H-A_laptop> oh...
[09:15:32] <A-L-P-H-A_laptop> <-- Canuck... knows nothing about lowriders
[09:16:56] <Phydbleep> Think '67 Chevy Impala with blue metal-flake paint, green fur interior and a chain steering wheel bouncing up and down ~ 6 feet. :)
[09:17:11] <A-L-P-H-A_laptop> I rather not.
[09:17:15] <A-L-P-H-A_laptop> I think they're dumb.
[09:17:35] <A-L-P-H-A_laptop> I prefer class... over ugly looking cars.
[09:18:41] <Phydbleep> * Phydbleep prefers performance and reliability and doesn't give a flying fornication what it looks like..
[09:20:32] <Phydbleep> Hehehe... I'm the type who gives something a paint job so hideous that nobody with eyes would want/steal it.
[09:20:51] <A-L-P-H-A_laptop> uh.
[09:21:00] <A-L-P-H-A_laptop> I was talking to my buddy over a coffee.
[09:21:14] <A-L-P-H-A_laptop> if I won the lottery... what would go into my car garage.
[09:21:36] <A-L-P-H-A_laptop> I think it'd be all american iron in there... no jap, or nazi stuff.
[09:21:46] <Phydbleep> Hehehe..I've had the same mountain bike for like 4 years.. Paid $15 for it at the end of the day at the flea market.. Hot Pink..
[09:22:04] <A-L-P-H-A_laptop> Pontiac Solstice would probably be definitely one of them... with a roll cage, and swapped engine.
[09:22:16] <A-L-P-H-A_laptop> Phydbleep, flaming.
[09:22:40] <Phydbleep> Hehehe... Once it hits the ground here and some maniac tweaks it, It's American. :)
[09:22:52] <A-L-P-H-A_laptop> lies.
[09:23:15] <A-L-P-H-A_laptop> it it's made in North American (Canada, US), I'll think about it.
[09:23:31] <Phydbleep> No crackhead self respecting or otherwise would be caught dead with something that color. :)
[09:23:32] <A-L-P-H-A_laptop> I'm a GM kinda guy... I don't know exactly why
[09:24:12] <Phydbleep> * Phydbleep has an '82 Grand Cherokee in the driveway at the moment.. American?
[09:24:43] <A-L-P-H-A_laptop> I've owned a 1987 Le Baron GTS... GrandAM SE '98. GrandAM GT 2002. Cavalier 2004. Buick Century 88.
[09:24:45] <Phydbleep> Then why all the replacement part stamped "Made in China"?
[09:25:12] <A-L-P-H-A_laptop> I can accept Quality Chinese Grade A parts.
[09:25:24] <A-L-P-H-A_laptop> I can accept Grade A parts made anywhere.
[09:25:54] <Phydbleep> And once they're re-assembled here they're American. :)
[09:26:01] <A-L-P-H-A_laptop> bearings made in China, are sooo cheap... and I can't figure out why
[09:26:17] <A-L-P-H-A_laptop> Phydbleep, that's made in America, I can accept that.
[09:26:20] <A-L-P-H-A_laptop> not imports.
[09:26:37] <A-L-P-H-A_laptop> I'm really not a jap car kinda person.
[09:26:54] <Phydbleep> All the parts are imports... Screwed if you do, Fscked if you don't. :)
[09:27:01] <A-L-P-H-A_laptop> I'll take BMW 645i. but that's only cause it's $120K USD car.
[09:27:52] <A-L-P-H-A_laptop> oh.
[09:28:00] <A-L-P-H-A_laptop> wow... 645i is $99,000CDN.
[09:28:02] <Phydbleep> ROFL... I'd average 240 cars for that. :)
[09:43:29] <Phydbleep> A-L-P-H-A: What is make that lathe? It looks like a Logan..
[09:43:41] <A-L-P-H-A_laptop> schuablin. swiss
[09:44:37] <Phydbleep> Ah.. Kind of hard to see it under all the accessories. :)
[09:45:30] <A-L-P-H-A_laptop> hehe.
[09:45:38] <A-L-P-H-A_laptop> lots of stuff.
[09:45:41] <A-L-P-H-A_laptop> lotsa toys
[09:45:43] <A-L-P-H-A_laptop> lots of junk
[09:47:38] <anonimasu> http://www.masak.se/beg/Abene-150.html
[09:47:51] <anonimasu> most likely that mill will go to work..
[09:48:07] <anonimasu> it's been used in a prototype shop.. never for any production runs
[09:48:17] <anonimasu> seems like it's in nice shape
[09:49:27] <anonimasu> * anonimasu is a jap car person
[09:52:39] <A-L-P-H-A_laptop> anonimasu, gonna get that?
[09:53:09] <anonimasu> most likely
[09:54:18] <anonimasu> my next car will either be one like the one I have now or a audo s4 avant..
[09:55:10] <anonimasu> audi..
[09:55:52] <anonimasu> I like s4 265 hp from factory
[09:56:09] <anonimasu> and awd..
[09:56:37] <A-L-P-H-A_laptop> yeah, the S4 was talked about
[09:56:42] <A-L-P-H-A_laptop> dunno what I'
[09:56:49] <A-L-P-H-A_laptop> d like for a 3rd car.
[09:57:12] <anonimasu> well I am to get a dog so my small jap car wont do
[09:57:12] <anonimasu> :)
[09:57:22] <anonimasu> and i cant live without AWD
[09:58:41] <Jymmm> dogsled
[09:58:54] <anonimasu> Jymmm: ?
[09:59:01] <Jymmm> APD == All Paw Drive
[09:59:07] <anonimasu> yeah
[09:59:18] <A-L-P-H-A_laptop> there's like, subaru
[09:59:27] <anonimasu> *chuckles*
[10:00:06] <anonimasu> A-L-P-H-A: what post did you use in mastercam for emc?
[10:00:13] <A-L-P-H-A_laptop> none.
[10:00:19] <A-L-P-H-A_laptop> I'm tinkering with tcnc.
[10:00:21] <A-L-P-H-A_laptop> turbocnc
[10:00:28] <anonimasu> ah..
[10:00:34] <A-L-P-H-A_laptop> <-- registered user of Turbocnc
[10:00:36] <anonimasu> if you want a emc post for visualmill I can give you one :)
[10:00:46] <anonimasu> I'll make a emc one someday for mastercam
[10:00:48] <anonimasu> but I am short on time
[10:00:49] <A-L-P-H-A_laptop> I would like that.
[10:00:57] <anonimasu> can you accept dcc's ?
[10:01:06] <A-L-P-H-A_laptop> A-L-P-H-A can autoaccept it.
[10:01:54] <anonimasu> dosent seem to work
[10:02:05] <A-L-P-H-A_laptop> let me check
[10:02:42] <anonimasu> A-L-P-H-A is blocking messages from unidentified users. You must register and identify with NickServ before talking to this user.
[10:02:50] <anonimasu> /mode A-L-P-H-A -R
[10:02:51] <anonimasu> ;)
[10:03:02] <A-L-P-H-A> try now?
[10:03:16] <anonimasu> still the same..
[10:03:23] <Jymmm> when "ripping" a piece of aluminum flatbar on a bandsaw, what speed and blade should I use to get the best finish cut?
[10:03:23] <A-L-P-H-A> email?
[10:03:28] <anonimasu> yeah
[10:03:48] <A-L-P-H-A_laptop> you won't get a good finish...
[10:03:54] <A-L-P-H-A_laptop> just mill the ends smooth
[10:04:03] <Jymmm> no mill (yet)
[10:04:13] <Jymmm> and it's rip, not ends
[10:04:14] <A-L-P-H-A_laptop> Jymmm, also depends on # of teeth
[10:04:28] <Jymmm> that's why I asked what blade to get/use.
[10:04:33] <A-L-P-H-A_laptop> "ripping"???
[10:04:39] <A-L-P-H-A_laptop> what the heck is ripping?
[10:04:48] <Jymmm> 36" long cut lengthwise
[10:05:20] <A-L-P-H-A_laptop> you want to cut flat bar into 36" lengths?
[10:05:33] <Jymmm> no
[10:05:44] <Jymmm> LENGTHWISE
[10:05:59] <A-L-P-H-A_laptop> why not just buy it in the proper size to begin with?
[10:06:08] <Jymmm> *sigh* nm
[10:06:10] <anonimasu> you've got it now
[10:06:16] <A-L-P-H-A_laptop> anonimasu, thanks
[10:07:23] <anonimasu> :)
[10:09:36] <anonimasu> *yawn*
[10:12:43] <anonimasu> I'll be off nwo
[10:12:44] <anonimasu> now
[10:12:47] <anonimasu> laters everyone
[10:14:22] <Jymmm> now? always!
[11:16:38] <nevyn_> nevyn_ is now known as nevyn
[12:21:53] <rayh> Hi Guys.
[12:44:55] <anonimasu> hello
[14:04:27] <alex_joni> hey guys
[14:04:35] <alex_joni> * alex_joni has been away
[14:09:13] <rayh> Hi alex.
[14:10:24] <alex_joni> hey rayh
[14:10:29] <alex_joni> how's the lathe?
[14:10:38] <rayh> How you doing today?
[14:10:57] <alex_joni> pretty fine
[14:11:02] <rayh> Good we have tool changer running in manual. Still a bit of work
[14:11:17] <alex_joni> nice... going for some automatic toolchanger?
[14:11:19] <rayh> Paul is supposed to get here sometime today.
[14:11:35] <rayh> We'll work on the big software issues then.
[14:11:46] <alex_joni> nice.. then you'll have some qualified helpers around ;)
[14:11:55] <alex_joni> * alex_joni counts rayh, matts, paul_c
[14:12:15] <rayh> We could have a party.
[14:12:18] <alex_joni> heh ;)
[14:13:23] <rayh> How is the weather there?
[14:13:47] <alex_joni> now it's ok.. stopped raining
[14:14:40] <rayh> Rain is okay for a while but sunshine is better -- at least where I am.
[14:16:20] <alex_joni> there were some heavy floods around here
[14:16:29] <alex_joni> some dams broke, too much rain, et
[14:16:30] <alex_joni> etc
[14:17:07] <rayh> Weather has been acting up of late.
[14:17:38] <alex_joni> yeah..
[14:17:38] <rayh> Floods that destroy old stuff are painful.
[14:17:48] <alex_joni> rayh: how much is servo_period now in emc?
[14:18:15] <alex_joni> http://www.cjtimis.ro/inundatii/UIVAR_OTELEC/UIVAR_OTELEC.htm (click on the links)
[14:18:34] <rayh> set from ini. default is 0.001 sec.
[14:20:32] <alex_joni> and base is 0.000050 ?
[14:20:40] <alex_joni> that's 50 usecs ?
[14:22:48] <rayh> Those pictures show some real damage. What a shame.
[14:23:43] <alex_joni> yup.. well that's life ;)
[14:23:46] <rayh> Period is used primarily by the stepping generators and can be set from >50 to about 10
[14:23:49] <alex_joni> I hope my house still stands
[14:24:20] <rayh> Are you at that level of flood plane?
[14:24:36] <alex_joni> I have a house in the same village
[14:24:41] <alex_joni> my own ;)
[14:24:51] <rayh> You would be welcome to move in with me if it's not?
[14:24:57] <alex_joni> unfortunately not assured :)
[14:24:59] <alex_joni> heh
[14:25:04] <alex_joni> I don't live there
[14:25:24] <alex_joni> but I bought it as an investment (was very cheap, so I don't mind very much)
[14:25:56] <alex_joni> about 1k EUR ;)
[14:26:07] <rayh> Yea but any loss is very real.
[14:26:31] <rayh> Matt, the real estate agent, laughs at the 1k EUR.
[14:27:01] <alex_joni> well.. if he wants I can get him some very cheap now
[14:27:10] <alex_joni> especially bc they are under water :D
[14:27:26] <rayh> Okay. Buy it all. <g>
[14:27:33] <alex_joni> lol
[14:27:49] <rayh> He'll advertise it as waterfront vacation property.
[14:27:49] <alex_joni> you might have a point
[14:27:57] <alex_joni> with indoor pool
[14:28:00] <alex_joni> LOL
[14:28:14] <rayh> rofil
[14:29:46] <rayh> Matt says to send him some listings and he'll see how much he can sell.
[14:32:35] <alex_joni> lol
[14:32:53] <alex_joni> think I'll go there this weekend to see what happened
[14:33:49] <rayh> Matt says he was in a row house in Baltimore the other day that had 18 inches 1/2 meter of water in the basement.
[14:35:04] <alex_joni> ouch ;)
[14:35:37] <rayh> There are some pretty run down places in that neighborhood.
[14:36:24] <dan_falck> hi guys
[14:36:50] <rayh> Hi Dan.
[14:36:57] <dan_falck> rayh: what have you guys got going on with the lathe so far?
[14:37:23] <rayh> We've got the most of the hardware conversion done.
[14:37:47] <rayh> Got pics up on linuxcnc.org/dropbox
[14:38:00] <rayh> They start with Hxx.jpg
[14:38:23] <rayh> Our plan was to get everything inside the two end boxes.
[14:38:34] <rayh> Good so far.
[14:38:40] <dan_falck> yesterday, you mentioned something about slaving encoders with HAL being nice
[14:39:02] <rayh> Having a bit of trouble with the 12 volt logic for the tool indexer and some limit switches
[14:39:45] <rayh> but a uln2803 handles the 5 up to 12 and 1k resistors and zeners are doing the other
[14:40:11] <rayh> Oh yes. To handle single point threading this would be great.
[14:40:59] <rayh> FredP and a few others worked out how to ramp an axis to spindle speed and then jump into geared
[14:41:06] <rayh> mode for the actual cut.
[14:41:12] <dan_falck> cool
[14:41:35] <rayh> I don't know where the code guys are with that yet.
[14:42:16] <rayh> Once we get all of HAL and BDI together in one place, EMC2, we will be able to move forward again.
[14:42:43] <rayh> alex_joni you guys got quite a way with HAL and 2.6 yesterday.
[14:43:01] <alex_joni> rayh: yeah.. but I'm afraid smthg's stll fishy in there
[14:43:19] <alex_joni> I managed to run tkemc, but any attempt to move would crach my pc
[14:43:23] <alex_joni> crash even
[14:43:51] <alex_joni> hal stuff isn't fully done (a lot of places need twisting to allow module extension .ko)
[14:44:03] <alex_joni> but I think it won't be long
[14:44:09] <rayh> True
[14:44:30] <alex_joni> I thought the hard part would be the build, but that seems to have been pretty easy
[14:44:31] <rayh> But it looked like the job of pulling it together is underway.
[14:44:43] <alex_joni> yup it is
[14:44:54] <rayh> When I left codeFest, the committment had been made but little coding.
[14:45:07] <rayh> I'm greatly encouraged by this work.
[14:45:17] <alex_joni> well.. I put myself as responsible for the 2.6 work on SF
[14:45:23] <alex_joni> so I had a reason for doing it :D
[14:46:12] <rayh> I'm glad that you did. I really like your work.
[14:46:35] <alex_joni> http://sourceforge.net/tracker/?atid=356744&group_id=6744&func=browse
[14:47:53] <alex_joni> hey Steve
[14:48:01] <stevestallings> Morning Alex
[14:48:14] <alex_joni> rayh: did you take any pics at CodeFest?
[14:48:25] <alex_joni> steve: how's it going?
[14:48:50] <stevestallings> drooling at the prospects of all the progress you guys are making on EMC2 updates
[14:48:58] <alex_joni> heh
[14:49:07] <rayh> No. Fred and Paul took a group pic at the end.
[14:49:23] <alex_joni> I hope to see some stuff progressing from Paul's & Fred's work on the TP
[14:49:30] <rayh> Don't know where it went. Will ask Paul when he gets here.
[14:51:18] <alex_joni> Martin took some pics
[14:51:31] <alex_joni> rayh: just /msg'ed you the link
[14:51:49] <stevestallings> I seem to remember taking a couple. Will see what I got.
[14:52:18] <alex_joni> steve: maybe we should set up a page about fest, and outcome (or maybe add those to the wiki)
[14:53:30] <stevestallings> I can put one together. Send mail to [email protected] with links to photos and other source material.
[14:54:18] <rayh> Whoa. Megapixels. That stalled out this box.
[14:54:50] <rayh> query stevestallings
[14:54:56] <stevestallings> yes
[14:56:05] <rayh> Someday I've got to learn how to do this stuff.
[14:56:18] <alex_joni> what stuff ray?
[14:56:28] <rayh> IRC
[14:56:32] <alex_joni> heh
[14:56:33] <rayh> and www.
[14:56:52] <rayh> Somedays I think I was born in the wrong age.
[14:57:28] <alex_joni> same here :)
[14:57:44] <alex_joni> sometimes I wish I was born in the PDC2 age
[14:57:54] <rayh> These images of martin's were taken mostly during the NIST tour.
[14:58:01] <alex_joni> yup
[15:00:00] <alex_joni> rayh: you're far more advanced on IRC & www & such than most people I know :D
[15:00:56] <rayh> I'm more comfortable at home cause I've got many of the commands written on the basement wall with a perminent ink pen.
[15:01:10] <alex_joni> that's nice :D
[15:01:21] <alex_joni> reminds me of what I do with robot-newbies
[15:01:32] <alex_joni> I make them write on the factory floor ;)
[15:01:46] <rayh> Good plan.
[15:01:46] <alex_joni> to draw axes (X- / X+, Y, Z ;)
[15:02:03] <alex_joni> till those wear out, they got them learned
[15:02:05] <alex_joni> :)
[15:02:26] <rayh> I did that when servicing a German made wood veneer splicing machine.
[15:02:45] <rayh> Each limit and solenoid was written in english on the floor.
[15:02:52] <alex_joni> yeah :D
[15:04:40] <alex_joni> anyways.. I'm going home now
[15:04:41] <rayh> Company bosses thought I was crazy until I got it running.
[15:04:49] <alex_joni> got my massage hours :)
[15:04:50] <rayh> Catch you after a bit.
[15:05:00] <alex_joni> yeah.. hopefully later
[15:05:11] <rayh> Let me know about your investment home when you get a look at it.
[15:05:20] <alex_joni> will do
[15:05:21] <alex_joni> bye guys
[15:12:49] <anonimasu> * anonimasu yawns
[18:49:13] <Imperator_> hi les
[18:50:17] <Imperator_> hi alex
[18:50:18] <alex_joni> greetings
[18:50:23] <alex_joni> hey Martin
[18:51:23] <Imperator_> * Imperator_ is desingning on his machine
[18:51:36] <alex_joni> nice
[18:53:06] <Imperator_> have to produce some parts before i change my job, because at my old one are staying arroung good machines
[18:55:58] <alex_joni> I see
[19:00:23] <Phydbleep> Imperator_: Makes me wish you worked at a place that builds anti-grav units.... :)
[19:00:40] <alex_joni> lol
[19:00:46] <Imperator_> :-)
[19:02:05] <Phydbleep> alex_joni: Laugh if you want, but that SouthBend was a pita to move out of the shop and onto the truck. :)
[19:02:23] <alex_joni> I guess...
[19:02:42] <alex_joni> /me wonders how to figure out the module extension used :)
[19:02:47] <alex_joni> * alex_joni wonders how to figure out the module extension used :)
[19:03:19] <A-L-P-H-A> hey folks
[19:03:31] <Phydbleep> alex_joni: 'ls /lib/modules/2.???/dirvers/kernel' ?
[19:03:52] <alex_joni> from inside a user-space .c file
[19:04:07] <alex_joni> it would be nasty to do that
[19:04:27] <Imperator_> where do you need that ?
[19:04:28] <alex_joni> I could use a define (-DLinux_2_6)
[19:04:28] <Phydbleep> Not really, Just test for a .o and a .ko file..
[19:04:39] <alex_joni> but I don't like that either
[19:04:44] <alex_joni> Imperator_: halcmd
[19:04:49] <alex_joni> loadrt part
[19:05:14] <Imperator_> test for the kernel version
[19:05:32] <alex_joni> from halcmd ?
[19:05:34] <alex_joni> yucky
[19:06:30] <alex_joni> darn.. now this is stupid
[19:06:36] <alex_joni> it's already there
[19:06:38] <alex_joni> :))
[19:06:45] <alex_joni> if .o fails it tries .ko
[19:06:47] <alex_joni> :))
[19:07:14] <Imperator_> why do they have changed this ???
[19:07:45] <alex_joni> for 2.6 (dunno who did it.. but I'm glad he did )
[19:08:18] <Imperator_> :-)
[19:18:19] <alex_joni> I got movement ;)
[19:18:42] <Phydbleep> alex_joni: Hopefully you wanted movement. :)
[19:18:48] <alex_joni> yeah
[19:18:52] <alex_joni> emc2 does move on 2.6
[19:18:56] <alex_joni> but... it hangs
[19:18:57] <alex_joni> :(
[19:19:08] <alex_joni> no ideea why
[19:19:43] <alex_joni> not sure how I can debug that :(
[19:20:26] <Phydbleep> alex_joni: strace?
[19:20:48] <alex_joni> don't know strace
[19:20:52] <alex_joni> what does it do?
[19:21:02] <Phydbleep> Debugging tool.
[19:21:58] <Phydbleep> I htink it will give you a running view of program execution/stack/memory..
[19:22:28] <alex_joni> running is not ok
[19:22:30] <Phydbleep> strace - trace system calls and signals
[19:22:43] <alex_joni> I need debug on what happened before I needed to hit the reset switch
[19:22:57] <Phydbleep> ptrace
[19:23:22] <Phydbleep> The ptrace system call provides a means by which a parent process may observe and control the execution of another
[19:23:22] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/hal/hal_lib.c: added a few more DEFINE_SYMBOL's in order to allow scope_rt to function
[19:23:32] <Phydbleep> process, and examine and change its core image and registers. It is primarily used to implement breakpoint debug-
[19:23:40] <Phydbleep> ging and system call tracing.
[19:23:54] <alex_joni> not sure it works on RT stuff
[19:24:13] <Phydbleep> it should let you log to a file for forensics.
[19:25:43] <Phydbleep> I had to use it years ago when I was re-writing a driver for a Happauge TV tuner card on slackware.
[19:26:46] <alex_joni> * alex_joni wonders if Phydbleep could do it again :)
[19:29:00] <Phydbleep> Probably.. I had 75% of the code (commented in German) so it was a dual translation job.. German > English, then EU spec >US spec.. I had all the docs for the Phillips chips on the board so it wasn't too bad.
[19:30:52] <Phydbleep> I never did get a decent translation of the term "Einstellung" though.
[19:31:01] <alex_joni> Setting
[19:31:35] <Phydbleep> That was the concensus, but hte context was wrong.
[19:38:19] <alex_joni> how come=
[19:38:23] <alex_joni> how come?
[19:39:22] <Phydbleep> I was using the find/replace translation method..
[19:39:40] <Phydbleep> So the context was pretty mangled to begin with.
[19:40:45] <alex_joni> heh
[19:40:51] <Phydbleep> And I only know enough German to get shot by a jealous husband or over-protective father. :)
[19:40:54] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/rtapi/Makefile: added MODULE_EXT to rtapi.conf so that scripts/realtime can figure out what extention to use on the modules to be inmoded
[19:42:01] <alex_joni> lol
[19:42:09] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/scripts/realtime: added MODULE_EXT to the modules to be inserted, so that it works on 2.6 too
[19:42:52] <Phydbleep> I have about the same grasp of Russian/French/Latin/Farsi..
[19:43:03] <alex_joni> farsi?
[19:43:23] <anonimasu> hey
[19:43:26] <anonimasu> I found a bug in emc2
[19:43:27] <anonimasu> :)
[19:43:30] <alex_joni> shoot
[19:43:38] <Phydbleep> * Phydbleep can scream "I didn't know she was your sister!" in 9 languages. :)
[19:43:38] <anonimasu> it locks in a mode (MDI/MANUAL/AUTO)
[19:43:49] <anonimasu> and refuses to move the mill..
[19:43:51] <Phydbleep> alex_joni: Farsi/Persian.
[19:44:15] <alex_joni> stepgen, siggen, _posemath, sincos,
[19:44:18] <alex_joni> an0n: explain
[19:44:28] <anonimasu> alex_joni: When I switched from MDI to manual..
[19:44:31] <alex_joni> sorry bout that.. was using IRC as a scratchboard
[19:44:42] <anonimasu> the mill wouldnt move or change modes..
[19:45:05] <anonimasu> I had to restart emc to get it moving again
[19:45:19] <alex_joni> hmmm.. that's a new one
[19:45:27] <anonimasu> yep
[19:45:37] <anonimasu> :)
[19:45:56] <anonimasu> I was going to do a mdi move to mill off some stuff in a box for mounting the plc's in..
[19:46:38] <Phydbleep> brb... Child + Cat + Tape == ERROR
[19:53:57] <Phydbleep> OK.. Back. :)
[20:00:03] <alex_joni> so Phydbleep..
[20:00:13] <alex_joni> care to dig into emc2 on 2.6 ? :)
[20:01:08] <alex_joni> I just got a clean compile (no warnings ,)
[20:02:44] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/rtapi/rtapi_math.h: added rtapi_math.h to act as a wrapper for math.h, it should get included by RT modules which need math.h
[20:03:42] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/rtapi/Makefile: added rtapi_math.h to the list of HEADERS
[20:06:02] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/ (4 files in 2 dirs): replaced include <math.h> with rtapi_math.h, to clear some compile warnings
[20:09:50] <alex_joni> an0n: if you're sure about the bug, file a bugreport pls
[20:10:31] <anonimasu> alex_joni: later..
[20:10:41] <anonimasu> I've already gone inside..
[20:10:58] <anonimasu> it'd be nice if I could get some more data when it appears..
[20:11:04] <alex_joni> right
[20:11:33] <anonimasu> I ordered components for spindle current feedback today
[20:15:03] <Phydbleep> alex_joni: Yeah, I'll take a whack at running the demo.. No servos/steppers here at the moment.
[20:15:16] <alex_joni> same here ;)
[20:15:23] <alex_joni> running dry at the moment :D
[20:15:29] <alex_joni> do you have a 2.6 patched?
[20:16:01] <Phydbleep> I CAN dummy up a logger on another box to get a log of the output though. :)
[20:16:12] <alex_joni> heh.. nice
[20:16:41] <anonimasu> so I hope to be able to get the stuff togther for it next week maybe
[20:16:42] <Phydbleep> Easy.. PLIP cable and monitor the port on the second box.
[20:18:11] <Phydbleep> I could also just prog a pic to watch the port and stream back the data on a serial line.
[20:23:23] <Jymmm> * Jymmm pokes MrMath!
[20:23:37] <alex_joni> who's mrmath?
[20:23:46] <Jymmm> he knows who he is!
[20:25:39] <Jymmm> in respect to water -vs oil quenching (like with acme rod), does that effect the finich as well?
[20:25:46] <Jymmm> finish
[20:25:53] <anonimasu> yes
[20:26:08] <Jymmm> will the oil leave a 'shiny' finish?
[20:26:09] <Phydbleep> Viscosity of the oil changes things too.
[20:26:22] <anonimasu> not nescessarily..
[20:26:32] <anonimasu> I'd quench in water.. if possible..
[20:26:39] <Jymmm> ok, will water leave that black finish?
[20:26:44] <anonimasu> no oil will
[20:26:53] <Jymmm> hmmm
[20:26:54] <anonimasu> more then water..
[20:27:13] <anonimasu> I am not sure if there's any diff but I've always thought it's a bit scary quenching in oil..
[20:27:13] <anonimasu> ;)
[20:27:24] <anonimasu> you need loads of oil to do it right
[20:28:02] <Jymmm> I know I'm goin cheap, but I was just thinking that if I could buy acme rod for a couple bucks more to get a better finish on it, that be a good thing
[20:28:15] <anonimasu> oh, I dont think that's possible..
[20:28:23] <anonimasu> you will most likely distory the rod by heating it up
[20:28:29] <anonimasu> distort..
[20:28:46] <Jymmm> Oh, no... I mean buying oil insted of water (as example)
[20:28:56] <Jymmm> err drillrod (sihg(
[20:29:00] <Jymmm> (sigh)
[20:29:24] <Jymmm> * Jymmm <---- Drain Bamage
[20:29:40] <Phydbleep> You have to heat it evenly and then flash it with the coolant or it will warp...
[20:29:49] <Jymmm> Worked on a design for a few days to find out at 4am it won't work.
[20:29:59] <Phydbleep> Bummer! :\
[20:30:10] <Jymmm> Phydbleep I'm talking buying pre-done.
[20:30:46] <anonimasu> rod/bar/stuff
[20:30:50] <Phydbleep> Jymmm: Are you talking about re-heat-treating it yourself?
[20:30:57] <Jymmm> Phydbleep oh gawd no
[20:31:06] <anonimasu> I think you need a oven to do it good
[20:31:15] <anonimasu> temperature/atmosphere controlled
[20:31:17] <Phydbleep> Ah... OK.. I was referring to diy. :)
[20:31:17] <anonimasu> one
[20:31:34] <Jymmm> Phydbleep I figured you were. =)
[20:31:43] <Phydbleep> anonimasu: That's why I'm building a 'pizza oven' :)
[20:32:02] <anonimasu> lol
[20:32:13] <anonimasu> man that's some pizza oven..
[20:32:17] <Jymmm> Phydbleep you just want pizza, forget the metal!
[20:32:18] <anonimasu> 0,3 sec baking time..
[20:32:39] <Phydbleep> 900F for the hot end of the dial. :)
[20:32:43] <anonimasu> HAHA
[20:32:45] <anonimasu> err
[20:32:48] <anonimasu> haha
[20:32:48] <anonimasu> neat
[20:33:10] <Jymmm> most pizza oven run acg 750 F
[20:33:14] <Jymmm> avg
[20:33:23] <Phydbleep> * Phydbleep found a way to cast furnace/oven parts from refractory concrete. :)
[20:33:24] <anonimasu> how many c is that
[20:33:24] <anonimasu> ?
[20:33:34] <anonimasu> I dont know F
[20:33:41] <anonimasu> or rather I dont care for F so I dont know it
[20:33:44] <Jymmm> 398C
[20:33:48] <anonimasu> oh..
[20:33:50] <anonimasu> way too cool :)
[20:34:05] <Jymmm> anonimasu google: 750f to c
[20:34:25] <anonimasu> yeah
[20:34:30] <Phydbleep> Hehehe... The materials are all rated for 3000F, So it really just depend on how much air/fuel I can feed it. :)
[20:34:48] <anonimasu> melting point for iron is at 1535c
[20:35:37] <anonimasu> http://www.threeplanes.net/toolsteel.html
[20:36:29] <anonimasu> have a look
[20:36:30] <anonimasu> ;)
[20:36:57] <Phydbleep> 900F = 482.22222222222222C
[20:37:24] <Phydbleep> 3000 F = 1648 C
[20:38:22] <anonimasu> yep
[20:38:29] <alex_joni> darn
[20:38:34] <alex_joni> I really start to hate this...
[20:38:47] <Phydbleep> * Phydbleep wanted the pizza 'well done'
[20:38:55] <anonimasu> ontinued heating to the hardening temperature (1450 - 1500� F) assures complete conversion to austenite. At this point the steel is no longer magnetic, and its color is cherry-red.
[20:38:59] <anonimasu> alex_joni: what
[20:39:21] <alex_joni> an0n: from there it depends on how you bring the steel back
[20:39:32] <anonimasu> yep
[20:39:37] <alex_joni> cool it fast you get marthensite afaik
[20:39:46] <anonimasu> * anonimasu nods
[20:39:48] <alex_joni> I hate emc2 crashing on me
[20:39:53] <anonimasu> * anonimasu does too
[20:40:07] <alex_joni> I hope it doesn't crash on 2.4
[20:40:17] <anonimasu> oh, I consider locking up the UI as bad ;)
[20:40:23] <alex_joni> I don't
[20:40:30] <Phydbleep> anonimasu: Waht wm?
[20:40:31] <anonimasu> that page was pretty good with info on hardening
[20:40:33] <alex_joni> deepfreezing my PC is
[20:40:34] <Phydbleep> wht
[20:40:37] <anonimasu> openbox
[20:40:42] <anonimasu> Phydbleep: that has nothing to do with it
[20:40:51] <anonimasu> Phydbleep: the ui stopped caring for mode changes..
[20:40:52] <anonimasu> or well emc
[20:40:53] <anonimasu> :D
[20:41:14] <anonimasu> * anonimasu whines
[20:41:27] <Phydbleep> OK.. Beacause I use twm for embedded stuff... Don't need all hte fluff and bloat.
[20:41:29] <Jymmm> have you guys played with hex bar at all?
[20:41:36] <anonimasu> I need to put some debugging in so I can check it myself..
[20:41:48] <alex_joni> you should ;)
[20:42:13] <Phydbleep> Hex bar is OK, but curse bricks are better. :)
[20:42:39] <Jymmm> Is it strong and less prone to warping/flexing than rod rod?
[20:42:50] <Jymmm> round
[20:43:15] <Phydbleep> Depends on the alloy.
[20:43:21] <Jymmm> equal
[20:43:47] <Phydbleep> * Phydbleep has seen tubing that is stronger than barstock.
[20:44:12] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/configs/emc.ini: changed motmod.o to motmod.ko, perhaps we should figure out extension during runtime and only have motmod here
[20:44:25] <Jymmm> yeah, that's kinda why I was asking. It would SEEM that it would be stronger, but nfc in real life.
[20:45:05] <Phydbleep> Same weight/length, just the diff in the shape.. The ridges/flats SHOULD make it marginally stronger.
[20:45:36] <Jymmm> only marginally?
[20:45:52] <anonimasu> heh
[20:46:17] <Jymmm> I was thiking that if you hit the metal store you're less likely to pick up a piece thats bent/warpped than you would round stock
[20:46:56] <Jymmm> even angle you can found warrped (over 20')
[20:47:12] <Phydbleep> Jymmm: You'd be better off with hex tubing.
[20:47:35] <Jymmm> Hmmm, haven't seen that yet, will have to look aorund.
[20:47:46] <Phydbleep> Jymmm: How big is the bar?
[20:47:56] <Jymmm> .750" flat-to-flat
[20:48:50] <Phydbleep> 3/4".. So.. ~1.4" flat-flat with a 1/4" wall for the same weight.
[20:49:15] <CIA-4> 03alex_joni 07kbuild-0-1 * 10emc2/src/ (6 files in 6 dirs): changed some Makefiles to copy modules to rtlib/ when 'make module_install' is run
[20:51:08] <Jymmm> can't even find hex tubing
[20:51:16] <Phydbleep> Jymmm: Even round tubing in the larger sizes is more resistant to bending than the rod.. And a lot easier to check quickly.. Pocet laser and sight down the center. :)
[20:51:25] <Phydbleep> pocket
[20:51:45] <anonimasu> pocket laser?
[20:52:04] <Phydbleep> Keychain laser...
[20:52:06] <alex_joni> one of those pointers
[20:52:09] <anonimasu> yeah
[20:52:12] <Phydbleep> Yeah.
[20:52:19] <anonimasu> but how would you check straightness?
[20:52:26] <anonimasu> mount and look?
[20:53:02] <Phydbleep> If you're really paranoid machine a pair of plugs to align the laser @ one end and an acylic target at the other.
[20:53:19] <anonimasu> lol
[20:53:20] <anonimasu> :)
[20:53:28] <anonimasu> very cool though
[20:53:49] <Phydbleep> * Phydbleep is full of strange ways to test stock. :)
[20:54:03] <anonimasu> I wish you could find drawings on how to build a interfereometer
[20:54:09] <anonimasu> the lasers are cheap nowdays
[20:54:26] <Phydbleep> Hehehe.. I had a laser on a lathe to set the centering 5 years ago. :)
[20:55:28] <anonimasu> although I better start saving to buy one
[20:55:57] <Phydbleep> * Phydbleep spends <$3 for semiconductor lasers.
[20:56:08] <anonimasu> * anonimasu nods
[20:56:25] <anonimasu> well having a laser dosent really help..
[20:56:55] <anonimasu> still need the optics and stuff
[20:57:22] <Phydbleep> Even a raw laser is really usefull at times. :)
[20:57:34] <anonimasu> heh
[20:57:40] <anonimasu> tell me more about it..
[20:57:46] <anonimasu> I was thinking about a interferometer ;)
[20:57:48] <anonimasu> *drools*
[20:58:14] <alex_joni> keep dreaming
[20:58:24] <anonimasu> yeah..
[20:58:30] <anonimasu> they arent exactly cheap..
[20:59:00] <anonimasu> and I dont really need one..
[20:59:26] <alex_joni> yup
[20:59:31] <anonimasu> hm, my source of electroncs dosent have lasers
[20:59:32] <anonimasu> cheap
[21:00:20] <anonimasu> :/
[21:00:22] <anonimasu> 121$
[21:00:24] <anonimasu> for a diode
[21:00:27] <Jymmm> I have one of the first "retail" laser pointers, very nice and runs off of 2 AAA batteries =)

[21:03:02] <Phydbleep> Proper link.
[21:04:05] <alex_joni> well.. I think I have all I did commited
[21:04:09] <alex_joni> running emc2 again
[21:04:31] <anonimasu> I'll look at in a while
[21:05:37] <A-L-P-H-A> wuzzup folks?
[21:09:17] <A-L-P-H-A> dollar store has lasers now too.
[21:09:19] <A-L-P-H-A> laser diodes.
[21:09:27] <A-L-P-H-A> with batteries to boot!
[21:10:54] <anonimasu> hm
[21:10:56] <anonimasu> nice
[21:10:57] <anonimasu> :)
[21:11:04] <anonimasu> you could slvage diodes off there
[21:11:13] <A-L-P-H-A> yup
[21:11:19] <A-L-P-H-A> $1.15CDN out the store.
[21:11:22] <anonimasu> nice
[21:11:24] <A-L-P-H-A> stupid 15% tax.
[21:15:37] <alex_joni> well guys.. think I'll call it a day
[21:15:56] <alex_joni> actually 2 days.. as it's tuesday already
[21:16:07] <A-L-P-H-A> aj, sec.
[21:16:11] <alex_joni> ok
[21:16:19] <A-L-P-H-A> do you happen to know how to calculate the amount of material removal from a 1hp motor?
[21:16:25] <alex_joni> nope
[21:16:31] <A-L-P-H-A> trying to figure out the proper feeds and stuff for my mill.
[21:16:31] <A-L-P-H-A> k
[21:16:38] <alex_joni> I'm not a machining guy
[21:16:46] <alex_joni> I do HW (and a bit of SW)
[21:16:48] <alex_joni> ;)
[21:16:52] <A-L-P-H-A> k
[21:24:35] <alex_joni> night guys
[21:27:17] <asdfqwega> ALPHA: what are you cutting?
[21:35:38] <asdfqwega> A-L-P-H-A: Assuming a sharp tool, 1hp available power, and cutting plain carbon steel - and a stiff machine - you can theoretically remove from 1.5 to 0.8 cubic inches per minute
[21:36:19] <asdfqwega> Your Mileage May Vary
[21:38:24] <A-L-P-H-A> asdfqwega, sorry. back... needed to help with dinner.
[21:38:59] <A-L-P-H-A> sharp, HSS 3/8" - 1/4" - 1/2" 3-4 flute cutter. on a 1hp motor [but let me find that plate rating].
[21:39:14] <A-L-P-H-A> 1" per minute sounds about good to me.
[21:39:26] <A-L-P-H-A> 1^3 inch.
[21:39:54] <A-L-P-H-A> I'm just gonna put some alu 6061 in there, and see what I can get.
[21:40:05] <A-L-P-H-A> watch me break some endmills.
[21:40:07] <A-L-P-H-A> :/
[21:40:11] <asdfqwega> There's other factors, yet - is it belt drive?
[21:40:33] <Phydbleep> asdfqwega: I got the Logan here and cleaned up. :)
[21:40:52] <asdfqwega> Phydbleep: cool
[21:41:21] <Phydbleep> Yeah, I'll have toolpost measurements for you later.
[21:42:34] <Phydbleep> And I found a Celeron 333 to throw in the DTK board.
[21:42:53] <asdfqwega> A-L-P-H-A: You said 1hp motor, but how it's coupled with the spindle reduces the available hp
[21:43:29] <Phydbleep> A-L-P-H-A: Gearup loses torque, geardown adds torque.
[21:43:54] <asdfqwega> Not torque - efficiency
[21:45:21] <Phydbleep> * Phydbleep always used the rule that 'rpm/X = torque * 0.95
[21:45:42] <Phydbleep> rpm/X = torque * (X * .95)
[21:46:42] <Phydbleep> Robin! :)
[21:47:05] <Phydbleep> * Phydbleep ducks the flying flash-bangs.
[21:53:27] <Phydbleep> asdfqwega: ~ 2"(W) x 2.25"(L) x 2"(H) for the main block..
[21:54:27] <robin_sz> * robin_sz bounces
[21:55:00] <robin_sz> today, I tried lasering some aluminium
[21:55:18] <robin_sz> the spare parts for the laser shoudl arrive tomorow :(
[21:56:33] <nevyn> ah.
[21:56:42] <nevyn> it went THAT well...
[21:56:49] <Phydbleep> ROFL
[21:57:31] <robin_sz> yeah
[21:57:42] <robin_sz> if it doesnt pierce, that energy has to go somewhere
[21:58:27] <Phydbleep> Reflected back into the emitter usually. :)
[21:58:45] <nevyn> right.
[21:58:48] <robin_sz> "turning in the widening gyre, the falcon cannot hear the falconer, things explode, mere anarchy is loosed upon the world"
[21:58:54] <Phydbleep> robin_sz: Got a nice pinhole in your upper mirror?
[21:59:00] <robin_sz> mirror?
[21:59:21] <robin_sz> no mirrors
[21:59:44] <nevyn> in the laser
[21:59:45] <Phydbleep> OW.. Don't tell me you slagged the yag. :\
[22:00:02] <robin_sz> nah, no damage to the laser itself
[22:00:12] <nevyn> what did you break?
[22:00:21] <robin_sz> just the ceramic on the nozzel holder
[22:00:38] <Phydbleep> Maybe he melted the WARNING sign?
[22:00:38] <robin_sz> exploded it did
[22:00:39] <nevyn> compounded alignment issues?
[22:01:11] <robin_sz> nah, just tried to go too quick
[22:01:22] <Phydbleep> robin_sz: What the power rating on that beast?
[22:01:36] <robin_sz> output, 700W of yag
[22:01:51] <robin_sz> well, 1K, de-rated
[22:01:58] <Phydbleep> Hehehe.. Lot bigger than the yag rod I have. :)
[22:02:01] <robin_sz> so it can keep the lamplife up
[22:02:25] <robin_sz> 24kw into the lamps
[22:03:03] <Phydbleep> * Phydbleep has one of the cigarette size yag rods somewhere for something to play with later.
[22:03:12] <robin_sz> and mirrors?
[22:03:17] <robin_sz> eliptical mirrors?
[22:03:57] <Phydbleep> robin_sz: me? Nope.. Optical pump in the uv is what i was thinking of trying.
[22:04:04] <robin_sz> hmmm
[22:04:14] <robin_sz> or pump it with laser diodes
[22:04:56] <Phydbleep> I can get a terrawatt (peak) pulse from a 4 foot nitrogen laser. :)
[22:05:13] <robin_sz> does it make a popping sound on the target?
[22:06:30] <Phydbleep> If I wasn't worried about being shot as a terrorist I could go up on the mountain and give Mexico (400km south ) a light show..
[22:06:42] <robin_sz> heh
[22:06:46] <robin_sz> what color is it?
[22:07:27] <Phydbleep> uv.. You have to pump an intermediate media to get a visible output from it..
[22:07:34] <robin_sz> dye laser huh
[22:07:59] <nevyn> I saw one of those at ANU
[22:08:01] <Phydbleep> And all kinds of things lase when you pump them with enough uv. :)
[22:08:04] <robin_sz> by the way, when are they changing you national anthem?
[22:08:34] <nevyn> they were trying to store a qbit in a crystal with it.
[22:08:52] <robin_sz> to remove that bit about "land of the free"
[22:09:03] <robin_sz> <Phydbleep> If I wasn't worried about being shot as a terrorist
[22:09:08] <robin_sz> sigh ...
[22:09:17] <robin_sz> we've lost havent we?
[22:09:25] <Phydbleep> * Phydbleep is getting ready and learning all the words to "Dumbass, Dumbass, Uber alles"..
[22:09:36] <nevyn> AMERICA...
[22:10:00] <nevyn> coming again to save the....etc
[22:12:15] <Phydbleep> robin_sz: We havent lost till the concrete sets. :)
[22:13:47] <nevyn> Phydbleep: I picked up a coherent innova 90 in hard rubbish ;)
[22:13:50] <Phydbleep> * Phydbleep is just waiting for all the jackasses to all be in the bunkers at the same time...
[22:14:11] <nevyn> it's only 6watts but I got galvo's ;)
[22:14:20] <nevyn> which reminds me..
[22:14:37] <Phydbleep> Who wants to grab a shovel and have a pothole patching party? We'd be doing community service. :)
[22:14:52] <robin_sz> I just have the 700W yag, a 450W CO2 and a 1700w CO2, oh and a hene tube :)
[22:15:50] <Phydbleep> ROFL @ robin_sz... # lasers and a flashlight with an attitude. :)
[22:15:55] <Phydbleep> s/#/3
[22:16:36] <robin_sz> I still yearn for a 632nm green laser
[22:16:54] <robin_sz> now, theres a good use for your YAG rod.
[22:18:09] <les> hi all
[22:18:27] <robin_sz> hey les
[22:18:34] <Phydbleep> I was looking at a multiple discharge path for the N2 laser.. Rotating the arcs around the yag and flushing the whole tube as a cooling measure...
[22:18:40] <Phydbleep> Les. :)
[22:18:42] <les> Paul is off to matt's place
[22:18:48] <les> and to see fred some more
[22:19:06] <robin_sz> les: did you get segmot cured?
[22:19:28] <les> Nope. Heres what we found:
[22:20:17] <les> Sadly we have pronounced SQ dead. No one can get the damned thing to work...not in 6 years
[22:20:23] <les> BUT
[22:20:56] <les> We have all but talked fred into doing or at least helping with a more conventional cubic or quintic planner
[22:21:14] <les> which could happen fast
[22:21:29] <robin_sz> * robin_sz nods
[22:21:41] <robin_sz> les: and you know what killed segmot? I do.
[22:21:53] <Phydbleep> So what is segmots major malfunction.
[22:21:58] <les> specifically...a cubic spliner is already in there...it's just in the wrong place
[22:22:36] <les> PHY it was just too ambitious and complicated. The major malfunction is:
[22:22:40] <les> it crashes!
[22:22:57] <robin_sz> les: what killed segmot is neither the "too ambitious" or "too complicated"
[22:23:03] <les> ?
[22:23:16] <robin_sz> what killed segmot is the crazy world of code it tried to live in
[22:23:32] <les> heh...yeah prob
[22:23:59] <robin_sz> in a nice ,clean, well thought out desing, a sement based planner would be doable and understandlable
[22:24:00] <les> the math was right...I know that.
[22:24:11] <robin_sz> but in emc as it is now? nightmare.
[22:24:23] <les> yes
[22:24:36] <les> emc2 is better but still bad
[22:24:46] <les> we were running emc2 here
[22:25:00] <robin_sz> but, everytime I say it, certian people just accuse me of being a troll, so fsck it. its dead as far as im concerend Im afraid
[22:25:38] <robin_sz> today, after playing for a few days with it on a old Brodgeport series 1
[22:25:47] <robin_sz> we ordered a Baldor ESB ...
[22:25:48] <les> it is bad. Our tests indicated that it could not even do smooth machining at Bridgeport rates
[22:25:55] <robin_sz> correct.
[22:26:02] <robin_sz> ours too
[22:26:23] <les> and bridgeport rates are very slow
[22:26:30] <robin_sz> * robin_sz nods
[22:26:52] <robin_sz> I thnk jmk has the best chance of getting this thing beaten into shape
[22:27:20] <les> Well without a solution We do not have a certain "product"....
[22:27:24] <les> but
[22:27:34] <les> may order some iron anyway
[22:27:38] <les> it's cheap
[22:27:40] <robin_sz> yeah
[22:27:53] <les> it's on the pacer site now
[22:27:54] <robin_sz> stick a baldor or G200x on it and be happy :)
[22:27:57] <Phydbleep> So what you're saying is segmot might live if somebody went through and rebuilt it except for the math routines.
[22:27:59] <les> heh
[22:28:20] <robin_sz> I think it will never live inthe current framework
[22:28:43] <robin_sz> and the cubic/quintic planner will have to be bodged on top of the current mess,
[22:28:54] <les> No PHY....emc will only live with the emc2 tree cleanup and a new TP
[22:29:01] <robin_sz> proabbly further discouraging anyone from sorting out the current mess
[22:29:10] <Phydbleep> TP?
[22:29:16] <robin_sz> trajectory planner
[22:29:18] <les> trajectory planner
[22:29:22] <Phydbleep> Ah.
[22:29:24] <robin_sz> * robin_sz hi fives les
[22:29:33] <les> heh
[22:29:59] <Phydbleep> * Phydbleep is really only interested in emc2.
[22:30:23] <les> It has been decided that all work will be done on that tree
[22:30:41] <robin_sz> emc2 caught my attention for a short while
[22:30:41] <les> the old one is such a mess...
[22:30:48] <robin_sz> I was just getting interested, when someone dumped the entirety of the old tree into it
[22:30:56] <robin_sz> it never recovered imho
[22:31:13] <les> It's better...but not quite ready for prime time
[22:31:20] <les> we ran it ok here
[22:31:28] <robin_sz> its still got 700 line switch statements
[22:31:30] <robin_sz> and worse.
[22:31:36] <les> heh yes
[22:31:36] <Phydbleep> Bleah!.. The old tree is for reference only.. Maybe steal a math routine or 4..
[22:31:50] <robin_sz> sorta
[22:31:52] <robin_sz> but ...
[22:32:09] <robin_sz> it should have been a clean sheet. the rebuild of the messaging layer was what was needed
[22:32:23] <les> yeah
[22:32:28] <robin_sz> bu the old messaging layer was installed and used as it was
[22:32:43] <asdfqwega> Dammit...I'm good at math, and I'd love to help, but my mind bogs down when I try reading code
[22:32:49] <robin_sz> exactly
[22:32:59] <robin_sz> I lot all interest at that point
[22:33:13] <robin_sz> still, apparently Im just trolling.
[22:33:16] <cradek> les: I still haven't seen a test program that kills SQ
[22:33:23] <les> We have also determined kind of a speed limit when using general purpose CPU for real time
[22:33:29] <les> Hi chris
[22:33:34] <asdfqwega> I've killed SQ
[22:33:43] <cradek> les: I think paul pronouncing it dead because he can't figure out a bug in a couple days is a little premature.
[22:33:45] <Phydbleep> * Phydbleep steals robin_sz's trolling motor.
[22:33:46] <cradek> les: hi
[22:33:58] <les> I guess test and real world differ some
[22:33:59] <robin_sz> les: go on, send him emcfine.tap
[22:34:13] <les> We have a new test program
[22:34:19] <robin_sz> the spiral?
[22:34:23] <les> I did the math and paul coded it up
[22:34:45] <les> makes a 3-d spiral with increasingly close points as it goes in
[22:34:50] <robin_sz> nice
[22:34:58] <les> very handy
[22:35:17] <les> will release it but paul wants to gpl it or something.
[22:35:29] <asdfqwega> Take the .dxf output from autotrace, scale it to my work area = 100000 moves of 0.001" or so
[22:35:31] <cradek> yeah, I wrote that too a while back. I didn't get a crash but I got pauses.
[22:36:00] <les> Chris: We are trying to get fred and anyone else to help with a simpler but more viable cubic or quintic tp
[22:36:21] <asdfqwega> I tried that a couple times. I got pauses a few times, and other times it would just stop
[22:36:31] <les> Fred says this is pretty easy
[22:36:40] <Phydbleep> les: You're limiting it to 5 axis?
[22:36:46] <cradek> les: I've seen you guys talking about that for a year but nobody has written a single line of code.
[22:36:50] <robin_sz> * robin_sz suggests digging out the foundations before piling any more towers onto the castle might be a good plan
[22:36:51] <les> emc has a cubic routine in it already
[22:36:58] <les> just in the wrong place!
[22:37:18] <cradek> les: also nobody has been able to say the title of the book that describes the algorithm, even though several people have asked for it on the list.
[22:37:30] <asdfqwega> [monty-ish] And they said you couldn't build a castle is a swap!
[22:37:37] <les> hmmm ok hang on
[22:37:38] <asdfqwega> s/is/in
[22:37:45] <robin_sz> asdfqwega: swamp
[22:37:48] <asdfqwega> s/swap/swamp
[22:38:02] <robin_sz> :)
[22:38:08] <robin_sz> so I built one.
[22:38:15] <robin_sz> it fell down
[22:38:15] <Phydbleep> Does this mean my BDI is going to burn down, fall over and sink into the backyard?
[22:38:19] <asdfqwega> It sank into the swamp.
[22:38:22] <robin_sz> :))
[22:38:25] <asdfqwega> So I built another.
[22:38:32] <les> "Introduction to Robotics" j. craig
[22:38:55] <robin_sz> asdfqwega: from wood. that burnt down.
[22:39:02] <les> Puls sat around outside in the nice spring weather reading it cover to cover
[22:39:17] <les> Paul
[22:39:26] <asdfqwega> Phydbleep: Maybe ;)
[22:39:31] <les> quite dated...1989
[22:40:07] <robin_sz> les: thats a good start, I get the impression that some of the coders on emc must have read "robbie the robot goes fishing" by mistake :)
[22:40:18] <les> heh
[22:40:34] <les> Well Fred and I both had this text in school
[22:40:50] <robin_sz> you were in school in 1989?
[22:40:56] <les> no
[22:41:00] <robin_sz> phew
[22:41:06] <Phydbleep> http://robotics.uta.edu/me5337/
[22:41:07] <les> I bought a more recent version later!
[22:41:15] <Phydbleep> logger_aj: bookmark.
[22:41:15] <Phydbleep> See http://193.226.12.129/irc/irc.freenode.net:6667/emc/2005-05-09#T22-41-15
[22:41:18] <cradek> les: can't find the message to answer
[22:41:53] <les> ?
[22:41:57] <robin_sz> sigh, why wont my doze box log into this samba server
[22:41:59] <robin_sz> silly thing
[22:42:09] <robin_sz> * robin_sz tickles it.
[22:42:14] <les> there are lots of old IEEE transactions on the subject too
[22:42:39] <robin_sz> of "robbie the robot goes fishing"?
[22:42:56] <les> They cost money if you get them on the web, but not much
[22:43:07] <robin_sz> weird,
[22:43:24] <robin_sz> the onely things that seem to cost money are pr0n and IEEE transactions
[22:43:53] <les> Cubic and quintic planner algos were research paper fodder twenty years ago
[22:44:17] <les> nowdays it is time optimal stuff etc
[22:45:52] <les> But anyway yes Chris there has been talk for years about this
[22:46:01] <les> talk and no action
[22:46:05] <les> I tried
[22:46:16] <les> got fred down here...
[22:46:33] <les> got rogier down here from holland to work on SQ...
[22:46:53] <les> I did what I could
[22:47:37] <les> I set aside a week of shop time for this recent testing bit
[22:47:56] <Phydbleep> http://www.rvg.ua.es/publications/gallardo98b-IEAAIE.pdf
[22:48:08] <Phydbleep> Try that for TP math.
[22:48:10] <Phydbleep> :)
[22:49:10] <les> genetic...heh
[22:49:48] <les> just a plain old four point look ahead cubic would be about 1000% better than TP/TC
[22:51:49] <Phydbleep> Maybe I'm just stupid, but i thought that all the major tp work should be in the g-code perverter..
[22:52:44] <les> Well it's a level down
[22:53:15] <les> Think of it as just another form of g-code
[22:53:21] <les> it is causal
[22:53:37] <les> so you could calculate a plan at any time
[22:53:45] <les> even store it in a file
[22:54:09] <Phydbleep> IE.. Retract the z before you traverse to mill the next pocket should be there.. Having the software second guess the operator is a bad thing as far as I'm concerned.
[22:55:04] <les> Well the tp we are talking about is just to allow proper smooth motion.
[22:55:48] <les> The current TP will choke on .1 mm spaced point and a requested 1.5 cm/sec feed rate
[22:56:10] <A-L-P-H-A> What's the difference between the following: end milling, face milling, slit milling? Is end milling, just using to mill material away? face milling, like with a fly cutter, to remove tiny amount of material? slit milling like milling slots?
[22:56:34] <les> pretty much
[22:56:38] <A-L-P-H-A> les, cool.
[22:56:53] <A-L-P-H-A> trying to determine feedrates for my mill. :/
[22:57:14] <les> milling slots is the hardest because one side is climb milling...the other not
[22:57:37] <A-L-P-H-A> les, yeah... I'm gonna rough it out, and then go with a finishing pass.
[22:57:46] <les> single flute sometimes works better in that case
[22:58:02] <A-L-P-H-A> I need a 1/4" slot, so I'll probably use a 3/16" endmill to rough the slot, and then pass the sides to get a nice finish
[22:58:17] <Phydbleep> Yeah, That's wht I was wanting to mill 0.050" per pass.. reduce the strain on the spindle.
[22:58:25] <Phydbleep> s/wht/why
[22:59:37] <les> ALPHA: that will be safe. Climb mill the two sides for a smooth finish.
[22:59:55] <A-L-P-H-A> climb mill? [I'm a newb]
[23:00:21] <A-L-P-H-A> k. I think I know.
[23:00:25] <les> um...
[23:00:26] <Phydbleep> climb mill.. You're cutting UP the hill.
[23:00:52] <les> cutter always compresses the material
[23:01:04] <A-L-P-H-A> my spindle is CW. So if I'm milling a hole/pocket, to finish, i'd go clockwise?
[23:01:06] <les> actually the opposite
[23:01:13] <A-L-P-H-A> or CCW?
[23:01:25] <A-L-P-H-A> no.
[23:01:28] <A-L-P-H-A> let me guess.
[23:01:31] <les> with climb milling the cutting forces will help to move the feed along
[23:01:39] <les> it is unstable though
[23:02:21] <les> It feels kinda like power sterring if done manually
[23:02:31] <les> steering
[23:03:00] <A-L-P-H-A> to finish mill something, lets say I want to mill the perimeter of a box... I'd go what direction if my spindle goes CW [normal]
[23:03:12] <A-L-P-H-A> it'd be like CCW around the perimeter right?
[23:03:32] <A-L-P-H-A> and CW for a poket/hole?
[23:03:33] <les> example: you are cutting the LEFT flank of a slot
[23:03:38] <les> CCW rotation
[23:03:53] <les> and feed away from you
[23:04:34] <A-L-P-H-A> les, uh, that's still some confusion. Lets say we have a donut. I want to mill the hole. What direction, say we started at 12oclock high
[23:04:37] <les> most manual machines like wood table saws, jointers, etc do not climb cur
[23:05:02] <les> another example
[23:05:11] <les> table saw...
[23:05:35] <les> rip a plank by pushing it in backwards from the back
[23:06:03] <les> (don't do it)
[23:06:21] <Phydbleep> No thanks, I like my walls with the number of holes they have now. :)
[23:06:21] <les> but with power feed machines it makes a much nicer finish
[23:06:23] <robin_sz> climb milling works OK on very rigid machines
[23:06:36] <les> right
[23:06:39] <A-L-P-H-A> well, I do'nt think mine's very rigid.
[23:06:39] <robin_sz> on a flexible machine, you can get runaway
[23:06:45] <robin_sz> positive feedback
[23:06:59] <A-L-P-H-A> screw it, I'll just figure it out by trial and error.
[23:07:01] <les> I run climb milling on the saws and moulders
[23:07:08] <les> but they have power feed
[23:07:45] <les> and almost all cnc finishing cuts are climb milled
[23:08:49] <les> the edge of the rotating tool is moving opposite of the feed direction...that's all it is
[23:08:54] <Phydbleep> A-L-P-H-A: You might be able to get away with 0.001 cuts on it.
[23:11:00] <Phydbleep> * Phydbleep has used that trick on sloppy machines.. Hog it out rough and then run 0.001" slow-feed finishing passes to get a good finish.
[23:12:14] <les> The less the cut...the less difference between climb and conventional milling
[23:12:48] <les> conventional pulls the chip up and forward...
[23:12:55] <les> climb down and back
[23:13:39] <les> easier to show than say I guess
[23:14:39] <Phydbleep> asdfqwega: You still here?
[23:20:20] <A-L-P-H-A> les, I understand now.
[23:21:02] <A-L-P-H-A> les, so climb milling a pocket would be would push the chips down the hole, while normal milling would shoot the chips up.
[23:23:15] <les> yeah
[23:23:31] <les> conventional milling tends to recut chips
[23:24:56] <les> But if the machine is not rigid you must do it that way
[23:25:21] <les> climb milling wants to "suck the work in"
[23:25:56] <A-L-P-H-A> I really don't mind going over the part to get a clean edge. I'm doing it via CNC anyways... so it's okay fo rme.
[23:26:07] <les> right
[23:26:34] <les> I usually do a .01" climb pass for a finishing cut on most stuff
[23:27:10] <A-L-P-H-A> I'm just going to undersize the slot, and mill it out to proper size. 1/4" slot is the target.
[23:27:20] <A-L-P-H-A> used a 3/16 endmill, and then just clean the edges.
[23:27:26] <les> good plan
[23:27:52] <les> a .25 cutter will make bigger than a .25 slot dure to instability
[23:28:08] <A-L-P-H-A> yeah... so I'll be good then.
[23:28:34] <A-L-P-H-A> the rest of it, I'll just use a 1/2" endmill to rough, and finish the outside and pocket. And then a 3/16" endmill for the two slots.
[23:28:48] <A-L-P-H-A> les, http://www.gallery.com/current/bracket.zip I think is the model.
[23:28:49] <les> that will work.
[23:33:21] <les> Oh Chris if you are still there...we had a faster box so I got my first look at axis
[23:33:28] <Phydbleep> A-L-P-H-A: Wrong url
[23:33:44] <les> I REALLY liked the appearance
[23:33:46] <A-L-P-H-A> les, http://www.lloydleung.com/current/bracket.zip I think is the model.
[23:33:50] <les> good marketing
[23:34:04] <les> looks very familiar and un intemidating
[23:34:05] <Phydbleep> The requested URL /current/bracket.zip was not found on this server.
[23:34:15] <A-L-P-H-A> les, http://www.lloydleung.com/gallery/current/bracket.zip I think is the model.
[23:34:22] <les> intimidating
[23:35:03] <Phydbleep> All that effort and it's a #%&#%&@ dwg file. :)
[23:35:06] <les> dead link, but I have seen it
[23:35:47] <A-L-P-H-A> I'll repost it as what?
[23:35:56] <A-L-P-H-A> png/dxf/stl?
[23:36:03] <Phydbleep> A-L-P-H-A: Don't worry about it.
[23:36:13] <A-L-P-H-A> for the future then?
[23:36:23] <Phydbleep> I'll see a jpg when it's done. :)
[23:38:21] <Phydbleep> Who's set up to mill steel in here?
[23:38:35] <A-L-P-H-A> what grade?
[23:38:41] <Phydbleep> * Phydbleep needs a dovetail cut.
[23:38:53] <A-L-P-H-A> 60degree?
[23:38:56] <A-L-P-H-A> 45degree?
[23:38:59] <A-L-P-H-A> 30 degree?
[23:39:03] <Phydbleep> 60 i think..
[23:39:09] <A-L-P-H-A> depth?
[23:39:18] <Phydbleep> 3/4"
[23:39:21] <A-L-P-H-A> not me.
[23:39:21] <Phydbleep> ?
[23:39:59] <les> start first roughing a rectangular slot.
[23:40:28] <Phydbleep> Yeah. Then 30/45/60
[23:40:55] <Phydbleep> D'Eaux.. 15/22.5.30
[23:41:07] <les> well at least a small diameter cutter so you don't have to try to hog the whole thing at once
[23:42:00] <Phydbleep> * Phydbleep needs new crossfeed blocks.
[23:42:04] <Jymmm> MrMath is back!!!!!!!!!
[23:42:35] <Phydbleep> I want 1 for a milling adapter and 1 for a spare. :)
[23:42:49] <Jymmm> les : Hey, what's the significance of 1.732 ?
[23:42:56] <les> hmm
[23:43:13] <les> it's not e...
[23:43:23] <les> is it PI/2?
[23:43:30] <les> I don't know
[23:43:35] <Jymmm> nfc, that's why I was asking oyu
[23:44:18] <dmess> high all...
[23:44:19] <les> let me check
[23:44:20] <robin_sz> root 3
[23:44:25] <Jymmm> les k
[23:44:26] <les> close
[23:44:30] <Jymmm> hi dmess and robin_sz
[23:45:22] <robin_sz> no, it is root 3
[23:45:22] <Jymmm> les : I was messing with hexagon, and came across 1.732
[23:45:38] <Jymmm> robin_sz root cubed?
[23:45:45] <les> confirmed it is root 3
[23:45:50] <les> just checked
[23:46:08] <Jymmm> * Jymmm with deer in headlight look... what is root cubed?
[23:46:26] <robin_sz> who said that?
[23:46:37] <les> the number mutiplied by itself that equals 3
[23:46:41] <Jymmm> ok what is root 3 ?
[23:46:45] <robin_sz> sqaure root of 3
[23:46:50] <Jymmm> oh
[23:46:56] <Jymmm> sqrt of 3
[23:47:09] <robin_sz> like root 2 is sqaure root of 2
[23:47:20] <les> I like sqaure better
[23:47:25] <les> that looks neat
[23:47:27] <Jymmm> robin_sz I get it now, never heard it phrased that way before is all
[23:47:37] <robin_sz> shrug
[23:47:44] <robin_sz> its standard maths speak
[23:47:47] <les> new word!
[23:47:58] <les> someone has to invent them!
[23:48:43] <Jymmm> robin_sz Come on, I found that (1.732) the backwards way =)
[23:48:47] <robin_sz> Jymmm: and what is the value of e?
[23:49:09] <Jymmm> 1E
[23:49:56] <les> I just think of the formal definition
[23:50:07] <Jymmm> robin_sz Hey, I was out getting stoned during those years of school =)
[23:50:13] <robin_sz> heh.
[23:50:28] <robin_sz> ok, easy one then ...
[23:50:30] <les> e is the root where e^x is the derivative of itself
[23:50:34] <robin_sz> i^^2
[23:50:45] <les> that is why it comes up so much in nature
[23:50:49] <robin_sz> yep
[23:51:15] <dmess> isnt it i before e except after c
[23:51:21] <les> ha
[23:51:26] <robin_sz> the original "natural" number
[23:51:31] <Jymmm> dmess : Yes, yes it is =)
[23:51:57] <Jymmm> * Jymmm is gonna order some of these http://www.xylotex.com/StepperMotor.htm
[23:52:35] <robin_sz> les: did you read that piece recently about pi not being as irrational as first thought
[23:52:47] <robin_sz> when done in hex
[23:53:06] <les> hmmm
[23:53:09] <les> no
[23:53:13] <dmess> oh now thats interesting...
[23:53:13] <robin_sz> it turns out ...
[23:53:17] <Jymmm> 3.14 in hexidecimal?
[23:53:36] <robin_sz> you can calculate the nth digit of pi, in hex quite easily, without knowing any of the rest
[23:53:58] <dmess> hmm...cool
[23:54:12] <les> well in some number bases it would be rational I guess
[23:54:18] <les> like base PI heh
[23:54:23] <robin_sz> yep
[23:54:42] <les> but we do this ten finger thing
[23:54:54] <nevyn> robin_sz: hrm.
[23:54:59] <les> should have been 21?
[23:55:00] <nevyn> robin_sz: url?
[23:55:10] <robin_sz> google for bailey plouffe
[23:55:23] <Jymmm> les how you do 3/16 with the ten finger thing?
[23:55:25] <nevyn> ta
[23:55:38] <robin_sz> http://www.math.hmc.edu/funfacts/ffiles/20010.5.shtml
[23:56:05] <les> the 3 and the 16 are ten finger type numbers.
[23:56:53] <Jymmm> and toes
[23:57:15] <les> remember I said 21
[23:57:22] <les> for guys anyway
[23:57:34] <Jymmm> 22 for the gals
[23:57:40] <robin_sz> 22:
[23:57:42] <robin_sz> ??
[23:57:43] <Jymmm> well, a few of the gals anyway
[23:57:44] <robin_sz> 23
[23:57:44] <les> heh
[23:57:51] <robin_sz> you aint been looking hard enough
[23:58:03] <les> hahahaha
[23:58:16] <robin_sz> right, and on that note ...
[23:58:17] <Phydbleep> Where's that leave me? I can count to 32 on 1 hand..
[23:58:18] <Jymmm> robin_sz : if a "gal" can do 23, sHE's all yours!
[23:59:10] <Phydbleep> And if i use both hands I can get to 1024. :)
[23:59:14] <les> without the extra one he was thinking of...they'd be not much fun.
[23:59:18] <les> haw
[23:59:26] <robin_sz> quite so.
[23:59:40] <Jymmm> lol @ les
[23:59:42] <les> heh
[23:59:46] <robin_sz> right
[23:59:50] <robin_sz> I must go to bed :)
[23:59:55] <Jymmm> G'Night robin_sz
[23:59:56] <les> I must go on that note too
[23:59:58] <robin_sz> night guys ...
