[00:00:04] <maddash> dogfishguzzler: 'aptitude show rtorrent'
[00:00:14] <maddash> has anyone here ever used automator?
[00:00:53] <dogfishguzzler> looks sweet
[00:03:20] <dogfishguzzler> I'm gonna have to break into the christmas bud to make this pain go away
[00:03:32] <dogfishguzzler> Nobody look
[00:04:32] <maddash> how come there's a wake of silence in here everytime I send more than 5 entries in 5 minutes?
[00:04:34] <toastydeath> sounds like a party in #emc
[00:04:56] <toastydeath> probably reverse rate limiting
[00:05:18] <eric_U> new rule: no more depressing questions
[00:05:31] <dogfishguzzler> I think I can do that
[00:05:42] <toastydeath> what are we classifying as a "depressing question"
[00:05:55] <dogfishguzzler> but before the rule is ratified, where should I bury my dog?
[00:06:02] <toastydeath> back yard
[00:06:07] <dogfishguzzler> right on
[00:06:09] <dogfishguzzler> Im done
[00:06:16] <eric_U> somebody else's back yard
[00:06:29] <dogfishguzzler> * dogfishguzzler is way ahead of eric
[00:06:34] <toastydeath> oh oh i got one
[00:06:39] <toastydeath> somebody else's FRONT yard
[00:07:01] <eric_U> depressing headline of the day: pitbull kills boy's make-a-wish pony
[00:07:11] <toastydeath> whaaat
[00:07:14] <toastydeath> link
[00:07:58] <dogfishguzzler> Holy shit, wait till my wife finds out her duran duran is gone
[00:08:18] <toastydeath> better queue that up first.
[00:08:47] <maddash> dogfishguzzler: go torrent it! pirate power!
[00:08:58] <eric_U> freakin' horses name was tombstone
[00:09:24] <eric_U> http://www.google.com/search?source=ig&hl=en&rlz=&q=pitbull+%22make+a+wish%22&btnG=Google+Search
[00:09:26] <eric_U> gotta go
[00:09:31] <toastydeath> epic, ty
[00:09:41] <dogfishguzzler> * dogfishguzzler will regain his library
[00:09:50] <dogfishguzzler> later eric
[00:14:14] <toastydeath> i am so glad everyone seems to be replacing high quality old cnc iron with the same brand with faster rapids
[00:14:30] <toastydeath> lots of apparently good machines with lower spindle and rapid speeds? sign me up
[00:17:17] <toastydeath> lots of good brands, same age as the machines at work, and the machines at work are still damn accurate
[00:17:24] <toastydeath> 80-85
[00:17:29] <toastydeath> in year
[00:17:33] <toastydeath> 6000-10k
[00:17:47] <toastydeath> and we sure don't baby the ones we have
[00:18:14] <Dalran> no way I could afford even that much for one.
[00:18:35] <toastydeath> some dudes pay that much for manual machines
[00:18:52] <toastydeath> older and in poorer condition
[00:19:01] <toastydeath> plus these machines come with boxes of tooling
[00:20:13] <Dalran> unfortunately, on the salary of a pharmacy tech it's hard to afford something like that.
[00:20:19] <toastydeath> probably.
[00:20:36] <toastydeath> but that's more like, when you've got a career going and you've got money to dedicate to a hobby
[00:21:25] <toastydeath> i'm waiting for that point myself
[00:21:50] <Dalran> on my 3rd career.
[00:21:54] <toastydeath> oh.
[00:21:55] <Ziegler> this has to be the typo of the day: Birds kill millions with bird flew...
[00:22:15] <Dalran> has to be multiple typos.
[00:22:49] <Ziegler> yes

[00:35:30] <jmkasunich> ;-)
[00:37:18] <jmkasunich> http://icanhascheezburger.files.wordpress.com/2007/12/funny-pictures-cat-pwns-dog.jpg
[00:37:30] <jmkasunich> dog will remember that forever
[00:37:37] <maddash> dogfishguzzler: did your music files live in ext3?
[00:37:38] <Dalran> scarred for life!
[00:39:21] <jmkasunich> another scar: http://icanhascheezburger.files.wordpress.com/2007/12/funny-pictures-horse-in-car.jpg
[00:39:50] <Dalran> poor horse.
[00:40:09] <Dalran> looks like that kid really scared him.
[00:43:35] <dmess> who scared whom more though is the question of the day..
[00:44:10] <Dalran> that poor horse will probably never take a carrot from a kid in a car again.
[00:45:06] <dmess> it looks like they all just FREAKED...
[00:45:41] <Dalran> humans should know better than to scare poor animals :}
[00:45:53] <jmkasunich> that horse isn't scared
[00:46:00] <jmkasunich> just saying hi
[00:46:09] <jmkasunich> the hooman on the other hand....
[00:46:13] <jmkasunich> needs fresh pants
[00:46:26] <dmess> the horse looks to have some jag reflex goin.. i wonder what the inside of the vehicle looked like afterwards??
[00:47:04] <dmess> gag..
[00:47:10] <Dalran> that too.
[00:47:10] <jmkasunich> nah, thats just horse laughter or a yawn or whatever - they do that open mouth thing a lot
[00:47:34] <dmess> let us dream..LOL
[00:47:48] <Dalran> jmkasunich, the horse psychologist.
[00:48:02] <dmess> and cnc tech...
[00:48:11] <jmkasunich> http://icanhascheezburger.files.wordpress.com/2007/11/funny-pictures-curious-cat.jpg
[00:48:13] <Dalran> minor detail.
[00:48:28] <Dalran> Sonic, take 3
[00:50:00] <dmess> experience comes from bad judgement...
[00:53:08] <dmess> i have 1 at work (hard copy lost the electronic one.)... a bald eagle and a cat on the railing of a deck... the CAT is approaching.. the caption is .... overconfidence......when everyday failure Just isn't enough
[00:55:49] <Dalran> hehe
[01:04:56] <maddash> firefox is pathetic
[01:05:07] <SWPadnos> so fix it
[01:05:12] <maddash> crashes every 3 hours
[01:05:29] <SWPadnos> you sure that's not your X server?
[01:05:48] <maddash> no, because I can pkill firefox-bin and reload it
[01:06:08] <SWPadnos> I've got FF on Windows systems, several versions of Ubuntu, and RHL, and I don't think I've had that problem
[01:06:17] <SWPadnos> and I leave it running for days
[01:07:00] <maddash> sure, anything can run for days if you just "leave it." Try opening 12 tabs at once, 6 of which have flash.
[01:07:41] <SWPadnos> I generally have 6-20 tabs open, and I use it actively almost continuously
[01:07:54] <maddash> :(
[01:07:59] <SWPadnos> and I leave it running overnight, and it's still fine in the morning
[01:08:14] <SWPadnos> I'm what you might call a power user ;)
[01:09:04] <SWPadnos> that's not to say that there are no problems with Firefox, but I do have a strong data opint that tells me that you may have some bad configuration or something
[01:09:14] <maddash> like?
[01:09:17] <maddash> xorg.conf?
[01:09:21] <SWPadnos> damfino :)
[01:10:01] <SWPadnos> I haven't done anything specific to make it work here, so I'm not sure what could cause the issues
[01:10:57] <Dalran> javascript can cause firefox to go funky, as can flash.
[01:11:01] <maddash> how many plugins do you have?
[01:11:26] <Dalran> there are some issues with the plugin system that cause memory leaks.
[01:11:47] <maddash> I've got Adblock, Flashblock, Better Gmail 2, SwitchProxy, and User Agent Switcher
[01:11:49] <SWPadnos> 8 plugins, one of which is disabled since the last update
[01:12:11] <maddash> so, it's either FF, flashplugin-nonfree, or some other plugin, or the freakin' gecko rendering engine itself.
[01:12:32] <Dalran> specially javascript apps like chatzilla can cause firefox to go wonky and suck down ram and lock.
[01:12:35] <SWPadnos> Chatzilla, CustomizeGoogle, DOM inspector, Foxgame, googlebar, googlebar lite (can probably get rid of one of those :) ), prefbar (disabled) and talkback
[01:12:41] <SWPadnos> also java from Sun
[01:13:08] <SWPadnos> and of course flash, acrobat reader, etc.
[01:13:28] <maddash> this is NOT fair
[01:13:32] <SWPadnos> heh
[01:13:36] <SWPadnos> run memtest lately?
[01:13:37] <maddash> are you running deep blue or something?
[01:13:42] <SWPadnos> heh
[01:13:46] <maddash> nope. what's this memtest?
[01:13:58] <SWPadnos> this is my 7 year old (nearly 8) Windows 2000 computer
[01:14:02] <SWPadnos> memory tester
[01:14:16] <maddash> package name?
[01:14:19] <SWPadnos> http://www.memtest.org/
[01:14:20] <maddash> memtester?
[01:14:27] <SWPadnos> you boot with it, it doesn't run from within the OS
[01:14:35] <maddash> damn.
[01:14:42] <SWPadnos> let it run overnight
[01:14:45] <Dalran> many distros have memtest as part of the install disk image these days too.
[01:14:53] <SWPadnos> yep, including the EMC2 liveCD
[01:15:09] <SWPadnos> but it's a somewhat older version, which doesn't recognize modern-ish chipsets
[01:15:28] <SWPadnos> get 1.70, the bootable ISO or floppy image
[01:17:03] <maddash> memtest86 or 86+?
[01:17:10] <SWPadnos> +
[01:17:13] <SWPadnos> the link I gave you
[01:17:16] <maddash> ok. brb.
[01:17:19] <maddash> rebooting.
[01:17:22] <SWPadnos> heh
[01:24:28] <maddash> 86+ looks like it'll take forever, considering that it's running at 800 MHz speed
[01:25:07] <SWPadnos> you should le tit run overnight, no joke
[01:25:10] <SWPadnos> let it
[01:25:19] <SWPadnos> 5 or 6 passes would be good
[01:25:22] <SWPadnos> at least
[01:25:27] <maddash> maybe later...
[01:25:40] <SWPadnos> sure - it's something to do when you're not trying to use the computer :)
[01:25:46] <SWPadnos> I just used
[01:25:46] <maddash> this is so frustrating, because it should run at 2GHz, not .7 Ghz.
[01:26:02] <SWPadnos> I just used it to find an error in my brand new Corsair XMS memory - very useful
[01:26:43] <eric_U> I wonder how long it would take me to move a wall
[01:26:53] <jmkasunich> depends on how big of a wall
[01:26:54] <eric_U> oh, no dear, that wall was always there
[01:26:57] <jmkasunich> and what its hilding up
[01:27:03] <jmkasunich> holding
[01:27:09] <eric_U> just a stud wall with drywall
[01:27:13] <eric_U> not holding anything up
[01:27:24] <JymmmEMC> eric_U 37 seconds.
[01:28:04] <JymmmEMC> oppps...
[01:28:21] <JymmmEMC> eric_U 3.7 seconds. Car, reverse, hit gas pedal
[01:28:28] <Dalran> 0.007 seconds.
[01:28:30] <JymmmEMC> wall moved =)
[01:28:31] <Dalran> after prep time
[01:28:38] <eric_U> trick is getting the car in the basement
[01:28:41] <Dalran> step 1, steal 50 feet of det cord.
[01:28:50] <JymmmEMC> eric_U oh no it's not =)
[01:29:05] <Dalran> park car in living room, surround car with det cord.
[01:29:06] <eric_U> and having enough car left to hit the wall
[01:29:13] <SWPadnos> the trick is getting the car *out* of the basement
[01:29:15] <JymmmEMC> eric_U never said we wouldn't move OTHER walls too =)
[01:29:22] <Dalran> bah.....
[01:29:22] <JymmmEMC> SWPadnos: There ya go!
[01:29:31] <Dalran> getting it out is easy too.
[01:29:32] <eric_U> that wasn't part of the problem statement
[01:29:36] <Dalran> case of dynamite
[01:29:38] <Dalran> under car.
[01:29:52] <Dalran> explosives solve nearly every problem.
[01:30:00] <SWPadnos> well, you can kill two birds with one stone. you get a new tool, and the house loses a drywall: Sawz-All
[01:30:11] <JymmmEMC> Dalran: what the hell... coulda saved a car and used the explosives to move the wall
[01:30:18] <eric_U> I'm thinking it will go faster if I just move it
[01:30:21] <JymmmEMC> SWPadnos: not in 3.7 s
[01:30:21] <Dalran> what's the fun in that?!?
[01:30:43] <eric_U> have the sawzall though
[01:30:53] <JymmmEMC> Dalran: well, you need somethign for the getaway car to get a safe distance from the falling debri
[01:30:54] <Dalran> I meant in not using car.
[01:31:03] <Dalran> I didn't say use your OWN car.
[01:31:04] <Dalran> sheesh.
[01:31:08] <eric_U> it would be better if I used a truck
[01:31:10] <Dalran> that's what neighbors are for.
[01:31:10] <JymmmEMC> Dalran: my bad
[01:31:26] <eric_U> everybody loves trucks
[01:32:19] <eric_U> problem is, my wife would notice if I cleaned up the basement enough to move the wall
[01:32:41] <Dalran> she would notice if you blew a hole in the floor of the living room too.
[01:32:49] <eric_U> likely
[01:32:52] <Dalran> but, give her your credit card and send her shopping.
[01:32:54] <Dalran> solves that problem.
[01:35:14] <jmkasunich> I wish I had a CNC mill
[01:35:14] <eric_U> http://www.flyinggiants.com/forums/attachments/fg42/78136d1196739688-50-extra-300-cnc-part-making-001.jpg
[01:35:25] <jmkasunich> that way I could mill the PC boards I need to make my CNC mill
[01:35:34] <eric_U> too bad we dont know anyone with any machine tools
[01:35:51] <eric_U> what boards do you need?
[01:35:56] <jmkasunich> to bad I'm too impatient for that
[01:36:17] <SWPadnos> $33/board rapid prototypes
[01:36:19] <jmkasunich> its just a simple board - 3 opto-coupled inputs, two relay outputs and a charge pump
[01:36:31] <jmkasunich> I'm building it on perfboard as we speak
[01:36:38] <SWPadnos> oh, go to Radio shack and see if they still have some proto boards on the markdown rack :)
[01:36:40] <SWPadnos> ah
[01:36:59] <SWPadnos> get out the wire-wrap tool!
[01:37:05] <eric_U> what's a charge pump?
[01:37:08] <jmkasunich> I hate wire-wrap
[01:37:11] <SWPadnos> heh
[01:37:11] <Dalran> heck, some even still have ferric chloride kits.
[01:37:26] <Dalran> charge pump turns low voltage into higher voltage.
[01:37:30] <jmkasunich> charge pump is a ckt that needs its input to constantly be toggling, or the output turns off
[01:37:45] <SWPadnos> ie, a watchdog
[01:37:54] <jmkasunich> its used as a safety cutout, if the puter dies, the input stops switching and the estop chain drops out
[01:38:00] <eric_U> I was curious how you made it
[01:38:15] <eric_U> diode, resistor and a cap?
[01:38:26] <SWPadnos> that's probably the simplest circuit you could use
[01:38:28] <jmkasunich> 74CH14 takes the parport signal, and ensures it swings rail to rail
[01:38:35] <SWPadnos> but not the one jmk would use ;)
[01:38:36] <jmkasunich> two diode and two caps are the pump
[01:38:51] <SWPadnos> and a threshold detect?
[01:39:01] <jmkasunich> the pump output will be around 8-10V, and will be applied to the gate of a mosfet
[01:39:18] <SWPadnos> oh, direct drive to the "switch"
[01:39:31] <jmkasunich> I have some 0.3 ohm mosfet arrays, 4 in a SIP, so two will be running relays and one will be on the charge pump output
[01:40:03] <eric_U> you are using steppers?
[01:40:14] <jmkasunich> yeah
[01:40:28] <jmkasunich> I know, charge pump is maybe a bit overkill
[01:40:37] <jmkasunich> but it will also kill the spindle motor
[01:42:58] <maddash> did you guys ever figure out that mesa fpga board?
[01:43:06] <eric_U> no
[01:43:42] <jmkasunich> I still intend to do HW stepping on my machine
[01:43:51] <jmkasunich> but I need to get it running first
[01:44:12] <eric_U> so you are planning on using the mesa for that?
[01:44:20] <jmkasunich> yes
[01:44:30] <jmkasunich> I was working on lots of mesa stuff in the spring
[01:44:37] <jmkasunich> but I had a major interruption over the summer
[01:44:41] <jmkasunich> (I got divorced)
[01:46:15] <jmkasunich> <pin drops>
[01:47:18] <eric_U> did you say something?
[01:47:27] <jmkasunich> who me?
[01:47:32] <jmkasunich> nah
[01:47:46] <eric_U> hey new rule, no depressing posts
[01:48:33] <jmkasunich> ok
[01:48:40] <eric_U> like the one I made above about the pitt bull eating the kid's make a wish pony
[01:48:51] <jmkasunich> my machine ran (under cnc control) for the first time this weekend!
[01:48:54] <jmkasunich> there - un-depressing
[01:49:07] <eric_U> did you make a penguin?
[01:49:09] <jmkasunich> no
[01:49:17] <jmkasunich> right now its only working in lathe mode
[01:49:22] <jmkasunich> still gotta hook up Z
[01:49:27] <jmkasunich> (mill Z)
[01:49:46] <jmkasunich> that gets confusing - the motors that are X and Y in mill mode are Z and X in lathe mode
[01:49:52] <eric_U> will it work as a cnc lathe?
[01:50:01] <jmkasunich> yes
[01:50:06] <jmkasunich> (its a shoptask 3-in-1)
[01:50:18] <eric_U> I've seen it
[01:50:44] <jmkasunich> right now I'm trying to get the jogwheel hooked up, but its one of those domino things
[01:50:55] <jmkasunich> the wheel is gonna mount where the existing spindle motor switches are
[01:50:57] <eric_U> what kind of jogwheel?
[01:51:04] <jmkasunich> so I gotta get the spindle motor contactors working
[01:51:09] <jmkasunich> hence the relays I'm perfboarding
[01:51:40] <jmkasunich> what kind? the jogwheely kind... 100 detents per rev, little crank handle
[01:51:56] <eric_U> that you found in the trash....
[01:52:01] <jmkasunich> yeah
[01:52:25] <jmkasunich> the company I work for used to do CNC controls, but got out of that business a few years ago
[01:52:44] <eric_U> did you get sold off?
[01:52:56] <jmkasunich> when they cleaned out the developement lab an amazing pile of stuff went out the door
[01:53:21] <jmkasunich> no, they just decided to focus on other things that were more profitable
[01:53:39] <eric_U> one of the guys at work used to work at a place that closed, they threw tons of industrial stuff away
[01:53:40] <jmkasunich> (I think the other players in the CNC biz were cleaning their clocks)
[01:54:09] <eric_U> I thought you told me you were at ab/reliance
[01:54:21] <jmkasunich> I am
[01:54:30] <jmkasunich> well, AB now, they sold off reliance to baldor
[01:54:38] <jmkasunich> AB did CNC controls back in the day
[01:54:41] <eric_U> but you didn't get sold with them?
[01:54:47] <jmkasunich> nope
[01:54:55] <jmkasunich> I started with reliance, doing drives
[01:55:17] <jmkasunich> the drives part got absorbed into rockwell / AB, and the motors part of reliance is what got sold
[01:55:28] <eric_U> I see
[01:55:47] <eric_U> mostly induction motors?
[01:55:56] <jmkasunich> yeah
[01:56:08] <jmkasunich> also DC, but thats a shrinking business
[01:56:27] <eric_U> I'm trying to find some brushless that I can afford at work, pricy
[01:56:50] <eric_U> I'm going to smoke them :)
[01:57:01] <maddash> 4digits-text
[01:57:34] <eric_U> baldor seems to have the cheapest motors
[01:58:23] <jmkasunich> you mean generic 3-phase 1-50HP motors?
[01:58:35] <eric_U> brushless servos
[01:58:44] <jmkasunich> oh
[01:58:56] <jmkasunich> I don't know anything about that side of the market
[01:59:30] <SWPadnos> eric_U, what's "pricy"? :)
[01:59:45] <jmkasunich> SWPadnos: more than anybody wants to pay with their own money
[01:59:45] <eric_U> $1k - $3k
[01:59:50] <SWPadnos> heh
[01:59:54] <SWPadnos> he did say it's for work
[02:00:00] <eric_U> it's more than I want to pay with someone else's money
[02:00:08] <SWPadnos> ok, that's a bit much. what power range are you looking for?
[02:00:14] <eric_U> considering I'm planning on smoking them
[02:00:24] <jmkasunich> on purpose?
[02:00:35] <jmkasunich> or are you just convinced that's what you'll do?
[02:00:35] <eric_U> I was hoping for 1/2 horse
[02:00:44] <eric_U> both :)
[02:00:52] <SWPadnos> so a 400W AC motor is enough
[02:00:59] <SWPadnos> do you need absolute encoders?
[02:01:02] <eric_U> no
[02:01:07] <jmkasunich> SWPadnos: you have something in mind?
[02:01:11] <eric_U> has to be pm
[02:01:20] <SWPadnos> permanent magnet?
[02:01:22] <eric_U> yes
[02:01:32] <jmkasunich> * jmkasunich has a new project on the back burner, looking for a spindle motor in the 1/2 kw range
[02:01:40] <SWPadnos> ok, aren't all (modern) AC motors permanent magnet?
[02:02:00] <jmkasunich> most AC motors are induction, by about 100 to 1
[02:02:02] <eric_U> just wasn't sure what you were thinking about
[02:02:07] <jmkasunich> servo motors are mostly PM tho
[02:02:10] <SWPadnos> sure - I mean AC servos
[02:02:32] <SWPadnos> I have some Yaskawa motors/drives here, 50 and 200W, 3000 RPM cont, 5000 RPM peak
[02:02:43] <SWPadnos> the line goes up to 4kW or something
[02:02:54] <jmkasunich> peak RPM? I guess that makes sense for motion control
[02:03:02] <jmkasunich> I'd want continuous though
[02:03:17] <SWPadnos> these are relatively expensive, but not too bad for units without the absolute encoders (those add $500 or so)
[02:03:28] <SWPadnos> what spindle speed would you want?
[02:03:37] <eric_U> spindle speed doesn't matter at all
[02:03:41] <SWPadnos> also, 200W isn't enough
[02:03:43] <SWPadnos> that was for jmk
[02:03:50] <jmkasunich> its gonna get belted to the spindle, so I have some latitude
[02:04:00] <eric_U> sorry :)
[02:04:02] <SWPadnos> heh
[02:04:14] <jmkasunich> I want to spin tools from 3/8" down to 1/16 or less, so I'll probalby have multiple ratios
[02:04:20] <eric_U> I've been thinking about putting a servomotor on my mill
[02:04:22] <SWPadnos> it's still $2k or so for the motor/drive combo
[02:04:29] <jmkasunich> oh....
[02:04:31] <jmkasunich> never mind
[02:04:35] <SWPadnos> hmmm - you may needa drill speeder or something
[02:04:56] <jmkasunich> whatsa drill speeder?
[02:04:58] <SWPadnos> Tapmatic has a 6x one I think (sometimes comes up on eBay
[02:05:02] <SWPadnos> spindle speed multiplier
[02:05:05] <jmkasunich> oh
[02:05:19] <jmkasunich> I was actually thinking of a light duty high speed spindle mounted next to the main one
[02:05:24] <SWPadnos> probably crappy if it's acalled a drill speeder though :)
[02:05:42] <SWPadnos> yep, or as one person linked to recently, a die grinder attached to an NMTB tool holder :)
[02:05:46] <jmkasunich> put a large pulley with a stubshaft into the main spindle collet, and belt drive the subspindle
[02:06:18] <jmkasunich> so far I have 8 ball bearing slides, and I just bought the table today
[02:06:22] <eric_U> fordom tool with the shaft running through the head
[02:06:25] <jmkasunich> http://www.smalltools.com/product_details.asp?cat_id=237_10&prod_id=67629
[02:06:57] <jmkasunich> I'm planning a stationary table, and small but rigid gantry
[02:07:36] <jmkasunich> work envelope around 12 x 20 x 10 or so
[02:07:44] <eric_U> those things are nice, pre-mistaked
[02:08:14] <jmkasunich> actually it doesn't have any divots on it
[02:08:27] <jmkasunich> the hole in the middle is threaded, for an eyebolt
[02:08:36] <jmkasunich> (it was intended as a sub-table for a large machine)
[02:08:42] <eric_U> see, that's what you do after you drill a hole by mistake
[02:08:56] <SWPadnos> heh - "I meant to do that"
[02:09:11] <eric_U> would be nice to be able to lift it off the table
[02:09:11] <jmkasunich> I thought you were supposed to drill it all the way thru and then stamp "oil" next to it
[02:09:40] <SWPadnos> 71077345
[02:09:49] <jmkasunich> the table weighs ~125 lbs
[02:09:53] <jmkasunich> SWPadnos: ?
[02:10:08] <jmkasunich> my goal is to have the machine break down into chunks that I can put in the truck
[02:10:11] <eric_U> probably be best to lift it mechanically
[02:10:14] <jmkasunich> and bring it to the CNC workshop
[02:10:15] <SWPadnos> heh - that's the pattern for 7-segment calculators to say "SHELLOIL" when you hold them upside-down :)
[02:11:02] <juanjo> hi
[02:11:08] <jmkasunich> hi!
[02:11:13] <SWPadnos> hi
[02:11:48] <juanjo> iam new to emc
[02:11:50] <juanjo> i try to retrofir a big machine
[02:12:01] <juanjo> a horizontal machine center
[02:12:21] <SWPadnos> ah yes, from Argentina
[02:12:35] <juanjo> yes
[02:12:48] <Gamma-X2> anyone ever deal with a ycm 40?
[02:12:55] <Gamma-X2> i think thats what my machine actually is.
[02:13:20] <SWPadnos> not me
[02:13:29] <juanjo> i planning to make a cross link bettewn the funcions vs impus output, a 3d MAZE!!!
[02:13:38] <juanjo> yaznac???
[02:15:05] <jmkasunich> juanjo: the biggest machine I'm aware of with EMC is the Mazak at the CNC workshop
[02:15:06] <jmkasunich> http://www.youtube.com/watch?v=vNn-Yr7it5s
[02:15:25] <jmkasunich> we have the toolchanger working, and got rigid tapping done last year
[02:15:33] <jmkasunich> (june of this year actually)
[02:15:38] <juanjo> great!!
[02:15:52] <jmkasunich> that project gets worked on for a week or two each year
[02:15:55] <jmkasunich> so progress is slow
[02:16:16] <juanjo> i see the details and basically my machine is a litle more complicated
[02:16:18] <jmkasunich> but the total time needed to do the retrofit is probably a few man-months
[02:17:00] <jmkasunich> here is us working on it in June: http://www.youtube.com/watch?v=l5q1rVKYLTQ&feature=related
[02:17:15] <juanjo> ok. i undertand , you working only 2 week a year??
[02:17:40] <juanjo> sorry for my english is very poor!!!!
[02:17:41] <jmkasunich> right - the CNC workshop is an annual gathering of CNC people
[02:18:06] <jmkasunich> the owner of the machine "donated" it, to be retrofit with EMC
[02:18:11] <jmkasunich> the existing control was broken
[02:18:37] <juanjo> ok so you come to this workshop, and implement your "house " work
[02:18:59] <jmkasunich> in 2005 we started - removed the old control, installed the PC, and tried to get the old servo amps to work properly
[02:19:09] <jmkasunich> but they didn't work right - too old
[02:19:14] <jmkasunich> so we replaced them
[02:19:14] <juanjo> i see a lot of guys!!!, where is this workshop?
[02:19:36] <jmkasunich> in 2006, we got the motion control working and made the first cuts - the toolchanger was partly working
[02:19:52] <jmkasunich> in 2007 we got the toolchanger working better and added rigid tapping
[02:20:04] <jmkasunich> it is in galesburg, Illinois, USA
[02:20:14] <jmkasunich> (a few hours by car from chicago, Il, USA
[02:20:54] <juanjo> illinois a great place to see!!!
[02:21:19] <jmkasunich> most people there are from the USA and canada, but we had one guy from china, at least one from england...
[02:21:22] <juanjo> near form Champaing?
[02:22:09] <jmkasunich> http://maps.google.com/maps?f=q&hl=en&geocode=&time=&date=&ttype=&q=galesburg+Il&ie=UTF8&ll=40.90521,-90.219727&spn=4.574583,8.64624&z=7&iwloc=addr&om=1
[02:22:11] <juanjo> several times i be invited to the mack cormik plaza in Hydraulics events
[02:22:52] <jmkasunich> maybe you should come next year: http://www.cnc-workshop.com/
[02:23:07] <juanjo> i assit a few times as invided lecturer to the FiU (florida international University) in miami
[02:23:39] <juanjo> thas be nice. assist to the workshop!!
[02:24:12] <juanjo> i own a Hydraulic Shop , and designing special equipments for customers
[02:24:28] <jmkasunich> it would give you a chance to see EMC on a large machine, and help to decide if it is right for your large machine
[02:25:04] <jmkasunich> most of the EMC developers will be there
[02:25:32] <juanjo> ist a great idea
[02:26:22] <juanjo> june is a good month to travel for me
[02:27:02] <juanjo> the machie We use to make Big bushing for the Sugar mills industries
[02:28:50] <juanjo> you are located in the American Cornbelt
[02:29:12] <jmkasunich> the CNC workshop is, yes
[02:29:24] <jmkasunich> in fact the shop is surrounded by fields
[02:29:24] <juanjo> the sprinfield is the same of the Simpsons??
[02:30:22] <juanjo> i see several citys familiar for me, i was a licenced HAM operator, when young
[02:30:38] <jmkasunich> http://maps.google.com/maps?f=q&hl=en&geocode=&time=&date=&ttype=&q=galesburg+Il&ie=UTF8&om=1&ll=40.951252,-90.48563&spn=0.035719,0.067549&t=h&z=14&iwloc=addr
[02:30:49] <juanjo> and seveeral times i contacted with hams in several cities
[02:30:59] <juanjo> looked in the map
[02:31:00] <jmkasunich> the buildings in the center of that picture are where the workshop is held
[02:31:17] <jmkasunich> (this is a closeup of the actual place)
[02:31:30] <jmkasunich> lots of corn and soybean fields all around ;-)
[02:31:46] <toastydeath> what do you dudes do at the workshop
[02:31:47] <eric_U> wikipedia says that Springfield is a fictional city in an unspecified state http://en.wikipedia.org/wiki/Springfield_%28The_Simpsons%29
[02:32:24] <ejholmgren> I would assume they build things with crazy metal working machines?
[02:32:39] <eric_U> nuclear powered
[02:32:49] <toastydeath> i thought last time they sat around on computers and used the mill table as a coffee bar
[02:33:23] <juanjo> ahh evary time i asked where is the simpson place!!!! mys boys likes sympsons
[02:34:08] <juanjo> ok, your contry is a big place, too big to see all in one live!!!
[02:34:25] <ejholmgren> you can see the good parts in one life
[02:34:41] <ejholmgren> ie. skip North Dakota, etc
[02:35:02] <eric_U> North Dakota is ok in the summer
[02:35:41] <ejholmgren> I grew up in Fargo and will never go back
[02:35:55] <eric_U> that's cheating then
[02:36:05] <juanjo> fargo, Dakota???
[02:36:16] <ejholmgren> my parent's took me across the border into MN when I was born
[02:36:24] <SWPadnos> Springfield Vermont was chosen as "the springfield" when the Simpsons movie came out
[02:36:39] <eric_U> SWP: that makes sense
[02:37:02] <eric_U> the pictures of springfield don't really look like Illinois
[02:37:16] <Gamma-X2> when i see this for a servo ( 72volt SEM ) what does sem stand for?
[02:37:18] <juanjo> i lives at Nort of Argentina the Citie is Tucuman. nar a 1million population
[02:37:25] <eric_U> SEM is a brand
[02:37:42] <Gamma-X2> ahhhh ok
[02:37:43] <SWPadnos> heh
[02:37:54] <SWPadnos> plus, there's a nuclear plant nearby, and it's run just about hw Homer would do it :)
[02:37:58] <SWPadnos> how
[02:38:06] <eric_U> all nuclear plants are run that way
[02:38:09] <eric_U> from what I hear
[02:38:20] <SWPadnos> hmmm. scary
[02:38:35] <SWPadnos> well, if we can't pronounce it, we probably can't run it
[02:39:02] <eric_U> the nuclear engineers took over the penn state Mechanical engineering department, 90% freaks
[02:39:16] <juanjo> in agentina is only 2 nuclear plants, the near to me is 600 km away!!!!
[02:39:18] <juanjo> the Twos are with Argentina Engeniering, also Sell to other countries, like Australia
[02:39:26] <eric_U> too bad the fact that I said that is going to go onto the google :)
[02:40:16] <SWPadnos> don't worry, the internet pipes may not be big enough to carry all this data
[02:40:36] <eric_U> I searched for something recently, and the logs of this irc came up
[02:40:58] <juanjo> so i happy to this!!!!, i remember the 2 mile, and of course chernovil
[02:41:16] <eric_U> it's 3 mile :), 2 mile after the accident
[02:42:01] <juanjo> Ha ha.. OK o forget the lengt of the island!!!!!
[02:42:12] <eric_U> I drive past that place a little too often
[02:43:41] <ejholmgren> :\
[02:43:48] <ejholmgren> do you speed up as you pass?
[02:44:01] <eric_U> I should
[02:44:27] <eric_U> I figure 3 mile island has reduced the growth rate of Harrisburg significantly
[02:44:44] <juanjo> ok...all i also speed up in yor place
[02:46:00] <eric_U> if you go past my place, you're lost, stop in and have a beer
[02:46:40] <juanjo> thanks
[02:46:54] <juanjo> at my charge
[02:47:37] <juanjo> you owns a CNCs machines?
[02:48:12] <eric_U> I have a bridgeport cnc, trying to get it working
[02:48:35] <SWPadnos> I have a Bridgeport manual mill, which may one day get converted to CNC
[02:48:39] <juanjo> ok nice machine
[02:49:04] <SWPadnos> and a bandsaw I may just motorize for hte heck of it
[02:49:08] <juanjo> knew mill??
[02:49:21] <SWPadnos> yep, mine is
[02:49:30] <eric_U> yes
[02:49:45] <scutsxg> hi,i have a question,how to got velociy plot in halscope of emc2
[02:49:58] <scutsxg> i cannt found it in that menu
[02:50:10] <juanjo> i have a UNIMAT 3 full equiped, and a Prazy MD300 fully with milling head, to use in my hobbyes
[02:50:34] <juanjo> wooden ships, and RC, planes and helys
[02:51:01] <eric_U> I have rc planes
[02:51:19] <jepler> scutsxg: you use a hal 'ddt' component to take the derivative of any signal you like. In the 'sim/axis' configuration, the Xvel, Yvel, Zvel, Xacc, Yacc, and Zacc signals are created by the .hal files. for other configurations you have to add it yourself.
[02:51:51] <juanjo> and i casting a machine to ba a gantry type mill 400x300mmx150mm
[02:52:23] <juanjo> i machined the table with the Tslot. i plannin using it with EMC
[02:52:31] <scutsxg> oh,jepler,thanks you are here....
[02:52:35] <jepler> uh oh
[02:52:41] <SWPadnos> heh
[02:53:14] <juanjo> but the Huller come first, so i learn with the big First
[02:53:44] <scutsxg> i surf your website,and could you give me some advice or refference source about your biarc interpolation?
[02:54:09] <juanjo> ok you have RC planes. i have 37 years of modeling, i 42 yrs old
[02:54:13] <scutsxg> i cannt understand your code biarc.py...
[02:54:55] <jepler> scutsxg: let me see if I can find one of the papers I read before writing it..
[02:55:31] <jepler> scutsxg: here's one: http://emergent.unpy.net/files/papers/V1Nos1to4_22.pdf
[02:55:32] <juanjo> my RC clud is http://www.tucumanradiocontrol.com.ar/
[02:56:25] <jepler> scutsxg: from that paper I followed the first few pages (finding points p1, p2, p3) and then ignored the rest
[02:56:56] <jepler> then I turn the arcs defined by p0, ts, p1, p2, p3, te into two gcode arcs
[02:57:19] <jepler> er, and p5
[02:57:23] <jepler> er, I mean, p4
[02:57:45] <jepler> p0, p4, ts, te can be found from the equation of a spline and its first derivative
[02:57:50] <scutsxg> oh,thanks jepler,i will read it carefully
[02:57:54] <jepler> good luck
[02:58:07] <jepler> the math is not easy for me either
[02:58:18] <juanjo> i planning to use the gantry to make models, i take my time to complete it, due i have not place to setup it, until 3 months more when my new hobby Shop is finished, i also have a complete System 3 form Siemens to play
[02:58:48] <juanjo> and learn form the germans
[02:59:39] <juanjo> everytime, i asked why the Siemes are too complicated in comparation with Fanuc, or Yaznac for example
[03:00:27] <eric_U> juanjo: you have a Corsair?
[03:00:33] <toastydeath> poor ui designers
[03:00:45] <juanjo> whe biy, a friend buy a itial made CN lathe the Control was Olivetti, a pain to put in services
[03:01:33] <juanjo> not nice plane the Vought F4U, but i not like very goog to flight ward birds
[03:02:25] <eric_U> I found a picture of you with your slowstick :)
[03:03:27] <juanjo> i preffer patern (i flyes Curares in the 80´s) and later soaring, and now i teah to my child of 11 and 5 ys , the rc modeling, the oldes flyes well a 3d Hely righ now
[03:04:14] <juanjo> yes the first flew in Argentina, is can see for my computer, was a success!!!
[03:07:31] <juanjo> Juan Ignacio is my son
[03:08:21] <eric_U> he's 11?
[03:08:50] <eric_U> I have a 12 year old son, I haven't taught him to fly yet
[03:10:11] <eric_U> I think this is the only one of my planes on the net: http://www.rcgroups.com/forums/attachment.php?attachmentid=1499309
[03:11:44] <juanjo> http://www.tucumanradiocontrol.com.ar/fotos.htm pictures from the club
[03:11:46] <toastydeath> i own panema
[03:12:04] <toastydeath> and all surrounding countries!
[03:12:20] <scutsxg> hi,i have a idea,is emc suitble to control a aircraft,sth like uav
[03:12:33] <eric_U> not really
[03:12:49] <juanjo> i think not
[03:13:01] <eric_U> but I keep thinking that rthal could be very useful
[03:13:24] <toastydeath> strap a fanuc 0T to it
[03:13:25] <toastydeath> and use that
[03:13:29] <juanjo> Nice plane, i make one very similar, i copied one called treedee, i see in hobby lobby
[03:14:35] <scutsxg> i do think maybe rcs is not only limited to cnc field
[03:14:54] <eric_U> yes, rcs was supposed to be general purpose control
[03:15:06] <jmkasunich> I like this one: http://www.tucumanradiocontrol.com.ar/images/fotosclub/pic23.jpg
[03:15:19] <eric_U> saw that:)
[03:15:22] <juanjo> My son flyes for 5 yrs old. is 11 now, so was the young pilot in Argentina
[03:15:45] <scutsxg> but it is very difficult to for diyer to control complex device due to time,money
[03:16:03] <eric_U> time is a problem
[03:16:08] <juanjo> is a very fast ones, is was from a friend,
[03:16:38] <eric_U> you can have a uav for less than $1000 now
[03:17:14] <scutsxg> oh,really
[03:17:24] <juanjo> hos is a uav, a plane autopiloted?
[03:17:34] <scutsxg> it is really interesting
[03:17:44] <eric_U> yes autopilot
[03:18:30] <juanjo> ok i see several boards to make it. some cheaps, and other expesives,
[03:18:35] <eric_U> simple approach: http://paparazzi.enac.fr/wiki/index.php/Main_Page
[03:19:08] <eric_U> their site is a little confusing due to all the different choices
[03:19:12] <juanjo> locally was a idea to make it to take pictures for the crops
[03:19:46] <eric_U> the FAA has shut that down in the U.S., it works well though
[03:20:32] <eric_U> there is a software company that uses aerial photos to diagnose crop problems
[03:22:00] <toastydeath> i will use tarot to diagnose crop problems and make millions
[03:22:21] <eric_U> if your method worked, the income would be substantial
[03:22:24] <toastydeath> WHO NEEDS AIRPLANES
[03:22:28] <toastydeath> WHEN YOU HAVE UH
[03:22:31] <toastydeath> GUESSING
[03:22:33] <juanjo> nice site,, yes the idea is get different spectral bands to "see" the problems or not, i see a demostration in a farm workshop
[03:23:52] <juanjo> Tarot, nice!!!!, Argentina is a Big client, the second exporter of Soybean, and the Fisrt in Lemons, so your maket is awaiting Wizard!!!
[03:24:34] <juanjo> i can represnt you? please!!
[03:24:46] <jmkasunich> ;-)
[03:25:44] <juanjo> nice chat, but is midnight in Tucuman, so i goint to sleep!!!
[03:25:54] <jmkasunich> goodnight juanjo
[03:25:55] <juanjo> going
[03:26:29] <juanjo> Goodnight sir. and everybody
[03:26:38] <juanjo> see later
[03:30:57] <jmkasunich> another lured into the den of iniquity that is #emc!
[03:32:23] <eric_U> better than mach
[03:32:36] <eric_U> those guys are really dangerous
[03:34:44] <toastydeath> hey did anybody else get the feeling that juanjo guy made everything he said up
[03:34:56] <jmkasunich> toastydeath: no
[03:35:02] <toastydeath> oh, okay.
[03:35:10] <jmkasunich> why do you think that?
[03:35:15] <toastydeath> i don't know, it was a feeling i got
[03:35:25] <eric_U> no, but I do have that feeling about you
[03:35:32] <toastydeath> hahaha, thanks.
[03:35:46] <eric_U> noproblem
[03:42:05] <jmkasunich> too much talking, not enough soldering
[03:42:22] <cradek> charge pump still?
[03:42:33] <jmkasunich> and relays and optos
[03:42:48] <jmkasunich> I have an incredible talent for being easily distracted
[03:43:01] <cradek> hey look over there
[03:43:19] <jmkasunich> ohhh,. shiny
[03:44:04] <jmkasunich> of course, if I was going to machine a board, I'd still be in eagle right now
[03:44:22] <cradek> heh
[03:44:38] <cradek> it goes pretty fast once you do it a few times
[03:44:57] <cradek> it's probably faster than point-to-point even for one-offs
[03:45:17] <cradek> #2, if you ever need it, is a huge win of course
[03:45:28] <jmkasunich> probably, as long as you aren't a layout freak like me
[03:45:30] <eric_U> I don't have the concentration to hand wire a board any more
[03:45:40] <eric_U> tried it the other day, it just about drove me crazy
[03:45:48] <cradek> jmkasunich: yeah jepler has that disorder too
[03:45:53] <SWPadnos> or a fine-pitch surface-mount freak like me :)
[03:46:10] <cradek> SWPadnos: I do soics all the time but avoid that smaller stuff
[03:46:24] <eric_U> I did a quick board in eagle, it wouldn't rip up and retry for me
[03:46:44] <jmkasunich> dammit, I just had a resistor go awol
[03:47:01] <Jymmm> jmkasunich: use a diode instead, same size
[03:47:01] <SWPadnos> the 0402-style multi-resistor packs are hard
[03:47:21] <SWPadnos> as are the 0.5-mm pitch QFP
[03:47:21] <jmkasunich> this is 1/4w thru-hole
[03:47:25] <jmkasunich> I must be going blind
[03:47:31] <eric_U> one time we were building with 8 pin opamps, and it disappeared. turns out it was stuck in the other guy's shoe
[03:47:34] <SWPadnos> still not worth it to look for it (if you have more)
[03:48:05] <SWPadnos> or you can try the trick we used to use: roll around a bit, you're guaranteed to get it stuck in a chair wheel
[03:48:24] <jmkasunich> heh
[03:48:29] <jmkasunich> I got another one
[03:49:06] <cradek> that'll help you find it too
[03:49:36] <SWPadnos> it was funny when I finally accepted the fact that it's just not worth it to look for those 0603 parts
[03:49:48] <SWPadnos> they cost 0.5 cents, so even thinking about looking for one is a net loss
[03:50:08] <jmkasunich> you have to hire someone in india to look for them
[03:50:13] <SWPadnos> yep
[03:50:19] <SWPadnos> but then the phone call is a loss :)
[03:50:45] <Jymmm> VoIP
[03:50:47] <eric_U> Indians work for approximately 30% of what we do
[03:50:55] <eric_U> outsourcing to them is a net loss in many cases
[03:50:59] <cradek> try fixing watches where you just learn not to lose things that size
[03:51:08] <SWPadnos> yeah, you have to go to Ireland to get cheap labor these days ;)
[03:51:19] <cradek> (I don't lose resistors either, I use the same strategies)
[03:51:21] <eric_U> I heard the Irish were doing pretty well
[03:51:36] <SWPadnos> there's a lot of electronic production going there, actually
[03:51:42] <SWPadnos> from chips to boards at least
[03:51:47] <Jymmm> SWPadnos: electronic bombs?
[03:51:56] <SWPadnos> of course not
[03:52:00] <SWPadnos> or at least, I wouldn't tell you
[03:52:29] <Jymmm> I was just saying what happened to the wind up clock detonators they were using.
[03:52:46] <SWPadnos> ?
[03:52:56] <Jymmm> IRA and all that
[03:52:58] <SWPadnos> you mean all those years ago? :)
[03:53:08] <Jymmm> what, 18 months ago?
[03:53:20] <SWPadnos> at least
[03:54:08] <Jymmm> snmpd is just kicking my ass
[03:54:24] <Jymmm> did I say that out loud?
[03:54:44] <SWPadnos> err - say what?
[03:57:45] <eric_U> I bought one of these today: http://www.amazon.com/Powermatic-1660795K-Model-66-10-Inch-Left-Tilt-5-Horsepower-/dp/product/B0000225S4/?tag=bretsreviews4-20&linkCode=asn&creativeASIN=B0000225S4
[03:57:51] <eric_U> wrong picture though
[04:00:53] <jmkasunich> there's a button on that screen for "add to baby registry"
[04:01:04] <eric_U> that's what I'm talking about
[04:01:05] <jmkasunich> baby needs a new table saw!
[04:01:08] <cradek> ha!
[04:01:21] <toastydeath> baby needs a 24" digital height gauge
[04:01:25] <eric_U> I bought my first saw just before my first child was born
[04:01:51] <SWPadnos> baby needs a 2000 square foot heated workshop with 3-phase power and heat
[04:02:09] <eric_U> now you're talkin'
[04:02:29] <SWPadnos> and 16 foot ceilings, unless there's a crane, in which case the ceiling height should be 22 feet or so
[04:02:49] <eric_U> have to have a crane
[04:03:44] <eric_U> the PM66 has a "wide stance" -- don't tell the Minneapolis police
[04:04:44] <eric_U> I could live with 1000 square feet if there was a crane
[04:05:07] <jmkasunich> yeah, aisles can be narrower
[04:05:23] <SWPadnos> well, you need the metal shop and the wood shop ...
[04:06:01] <jmkasunich> don't forget the electronics shop
[04:06:11] <eric_U> sounds like my basement
[04:06:12] <SWPadnos> oh, well that goes without saying
[04:06:21] <eric_U> and don't forget the airplanes
[04:06:22] <SWPadnos> and the welding area
[04:06:31] <SWPadnos> plus the environmental test chamber(s)
[04:06:33] <eric_U> welding area is one thing I'm missing
[04:06:43] <toastydeath> sychrotron
[04:07:06] <eric_U> research nuclear reactor
[04:07:48] <toastydeath> pencil making machine
[04:08:08] <eric_U> goes without saying
[04:08:15] <eric_U> except you said it
[04:08:17] <SWPadnos> and waffle iron
[04:08:50] <toastydeath> there is probably a parallel universe where i didn't say it but everyone did think it simultaniously
[04:08:51] <eric_U> bathroom with a toilet with two flush handles!
[04:09:16] <SWPadnos> like a nuclear toilet - takes two people to flush
[04:09:39] <toastydeath> saftey lockouts on industrial machinery
[04:09:49] <toastydeath> "hands clear!"
[04:10:06] <eric_U> I need one of those Ingersol-Rand compressors with the impellers instead of pistons
[04:10:28] <jmkasunich> screw compressors?
[04:10:34] <eric_U> that too
[04:11:07] <jmkasunich> we talked to them when we were working on liquid cooled VFDs - they wanted us to make a drive for their air compressors
[04:11:19] <jmkasunich> only problem is that their idea of "coolant" was oil at 80C
[04:11:26] <eric_U> that's a good idea
[04:11:33] <jmkasunich> we needed water at 40C
[04:12:56] <eric_U> I don't see them having water available
[04:13:46] <eric_U> I take it this was for a wind-tunnel worthy compressor
[04:13:50] <toastydeath> heat pumps?
[04:14:12] <jmkasunich> eric_U: no, just an industrial screw compressor - couple hundred HP
[04:14:16] <eric_U> heat pump is probably counter productive since the vfd is for energy savings
[04:14:22] <toastydeath> o
[07:33:47] <jmkasunich> gawd, that took _way_ too long
[07:35:58] <Jymmm> jmkasunich: soldering?
[07:36:04] <jmkasunich> yep
[07:36:15] <Jymmm> neck sore yet?
[07:36:31] <jmkasunich> not really
[07:36:37] <Jymmm> luck you =)
[07:36:47] <Jymmm> y
[07:36:50] <jmkasunich> yeah, I expected it to
[07:37:10] <eric_U> I get sinus problems, not so much sore neck
[07:37:22] <jmkasunich> flux fumes?
[07:37:30] <eric_U> yeah
[07:37:36] <Jymmm> Got Fan?
[07:37:45] <eric_U> not a bad idea
[07:37:56] <jmkasunich> I don't have that much smoke
[07:38:01] <Jymmm> just a lil 6" one, could evne be battery operated
[07:38:16] <jmkasunich> more time spent positioning parts, etc, than actually soldering
[07:38:36] <jmkasunich> and more time spent procrastinating than anything else
[07:38:53] <Jymmm> jmkasunich: LOOK! A pebble on the ground!
[07:39:03] <jmkasunich> mount 2 parts, solder 3 wires, play a game, mount another part...
[07:39:18] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[07:40:17] <jmkasunich> swampy doesn't know if he's coming or going
[07:40:39] <jmkasunich> I'm definitely going, to bed
[07:40:42] <jmkasunich> night folks
[07:40:48] <Jymmm> G'Night
[07:41:07] <eric_U> you can play the trebuchet game

[08:03:52] <anonimasu> morning
[11:25:41] <alex_joni> * alex_joni hugs CIA-24
[11:30:08] <anonimasu> tomp2:
[12:34:20] <cradek_> cradek_ is now known as cradek
[12:36:56] <BigJohnT> If I want to force a parport pin TRUE from the HAL Configuration window using the Test HAL command: what syntax would I use?
[12:39:10] <alex_joni> an output pin?
[12:39:17] <alex_joni> setp parport.0.pin-03-out 1
[12:39:30] <alex_joni> but it only works if the pin is not connected to anything in HAL
[12:39:40] <alex_joni> if it is, you need to "unlinkp" it first
[12:40:17] <BigJohnT> ok thanks
[12:43:50] <BigJohnT> alex_joni: hmmm, I did that and parport.0.pin-08-out toggled to true but my led on my breakout board did not come on...
[12:45:47] <BigJohnT> I just did pin 02 and it works as expected
[12:45:58] <BigJohnT> my problems yesterday may be due to this
[12:47:29] <BigJohnT> I had a feeling it might be someting here that is why I did not file a bug report yet I wanted to do more testing here first
[12:55:42] <BigJohnT> I swapped the parport out pin to 17 and the M64/M65 works fine! Whats up with my other output pins?
[12:56:54] <skunkworks> do you know if your printer port is 5v or 3v logic?
[12:57:21] <skunkworks> if it is 3 - it may not be enough to stear your bob
[13:52:37] <The_B> The_B is now known as the_ball
[13:54:21] <skunkworks> the_ball: hey - how are things in Norway? (was it Norway?)
[13:56:01] <jlmjvm> morning skunkworks
[13:57:02] <skunkworks> good morning
[13:57:08] <skunkworks> how are things going today?
[13:57:34] <jlmjvm> going good,getting my mill back together this week
[14:00:32] <skunkworks> nice
[14:05:52] <jlmjvm> skunkworks:are you in wisconsin
[14:06:29] <skunkworks> es
[14:06:30] <skunkworks> yes
[14:06:52] <skunkworks> trempealeau (near lacrosse, wi or winona, mn
[14:06:54] <skunkworks> )
[14:07:59] <jlmjvm> are you close to Menomonee Falls
[14:09:02] <jlmjvm> may be there for a couple days after the 1st
[14:10:47] <skunkworks> other side of the state.. :) what is going on there?
[14:13:05] <jlmjvm> if i buy a seat of synergy will be going up to learn a few things about the software
[14:25:23] <jlmjvm> i noticed tractor supply has a plasma cutter for a decent price,wonder if it could be used on a machine
[14:25:28] <jlmjvm> http://www.tractorsupply.com/webapp/wcs/stores/servlet/ProductDisplay_10551_10001_36332_______14151|14220|14238|36332?listingPage=true
[14:25:38] <skunkworks> ah - he is on here sometimes I think
[14:26:21] <jlmjvm> the synergy guy,bob?
[14:26:41] <jlmjvm> he told me he knows some of yall
[14:28:59] <jlmjvm> he fixed my video for me one day over the internet
[14:29:34] <skunkworks> heh
[14:29:46] <skunkworks> I think he is webadmin or something like that
[14:30:48] <alex_joni> he's a very nice guy
[14:30:54] <alex_joni> used to hang around in here
[14:30:57] <skunkworks> Hi alex
[14:30:59] <alex_joni> (but that was a while ago)
[14:31:13] <skunkworks> probably 6 months or mor
[14:31:14] <skunkworks> more
[14:31:19] <jlmjvm> called him on the phone,he told me some commands to enter in terminal,then bam he fixed it for me,very nice
[14:31:54] <skunkworks> for creating synergy - I am sure he is very versed in linux
[14:31:55] <jlmjvm> hello alex
[14:42:07] <alex_joni> hi
[14:44:51] <jlmjvm> alex_joni:gonna be getting my mill going again later this week,will the encoder setup be similar to the setup i used in 2.1.7
[14:46:38] <alex_joni> probably so
[14:48:09] <jlmjvm> excellent
[14:51:35] <alex_joni> bbl
[15:09:28] <cradek> morning ray
[15:10:42] <rayh> Hi Chris
[15:12:44] <cradek> http://i11.ebayimg.com/01/i/000/cb/ff/2a87_1.JPG
[15:12:51] <cradek> uh, think that parallel is homemade?
[15:13:17] <cradek> something seems unusual about the hole spacing, but I can't put my finger on it
[15:13:55] <skunkworks> looks almost diagonal.
[15:14:12] <skunkworks> hard to tell.. It may be just used hard
[15:14:20] <cradek> skunkworks: look at the holes
[15:14:35] <skunkworks> oh - spacing sucks also ;)
[15:14:47] <archivist> apprentice parts
[15:15:07] <skunkworks> cradek: 94 people have looked at your video
[15:15:30] <cradek> I will make some more when I get the C axis working too
[15:15:40] <skunkworks> can't wait
[15:15:41] <cradek> hopefully, videos of cutting some neat parts
[15:15:44] <cradek> me too
[15:16:59] <cradek> it's nice to have a camera that does videos now
[15:17:03] <rayh> start drilling from both ends and work to the middle.
[15:19:06] <rayh> logger_emc "bookmark"
[15:19:30] <rayh> that didn't work.
[15:19:35] <cradek> logger_emc: bookmark
[15:19:35] <cradek> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-12-19.txt
[15:19:45] <rayh> thanks
[15:20:33] <cradek> rayh: I wish you could see the video of my (not quite finished) 5 axis desktop machine
[15:20:56] <cradek> it's about 1:40 on youtube. I wonder if you could see it with some patience
[15:21:16] <skunkworks> it is here http://youtube.com/watch?v=0jQy-zc5P6w
[15:21:36] <skunkworks> just let it buffer for a minute or 30 ;)
[15:28:05] <alex_joni> hi rayh
[15:28:12] <alex_joni> I'm just replying to your email :)
[15:28:13] <rayh> I wish I could see it also.
[15:28:18] <rayh> Hi Alex
[15:28:31] <rayh> My quandary?
[15:28:34] <alex_joni> btw, could you /join the board channel for a bit?
[15:28:42] <alex_joni> what's a quandary?
[15:28:48] <rayh> Chris is that a stacked BC
[15:29:11] <cradek> no, the head tips for B. C will rotate horizontal on the table
[15:29:15] <rayh> Sure is it just plain board or is there a date after?
[15:29:19] <alex_joni> C on the table, B mounted on Z, moves the spindle
[15:29:22] <rayh> Okay.\
[15:29:23] <alex_joni> plain
[15:30:23] <rayh> A quandary is a state of confusion.
[15:30:33] <rayh> I live there most of the time.
[15:31:43] <alex_joni> well.. in that case I'm the source of your m66 quandary
[15:31:45] <alex_joni> :P
[15:39:13] <jlmjvm> that is a cool video,curious to see how it actually drills in material
[15:40:14] <cradek> thanks. those are g83 peck drill cycles. I have experimental code to allow them in any direction on a 5 axis machine.
[15:41:26] <jlmjvm> super cool,was wondering if you were able to use standard drill commands,g81,g83
[15:41:58] <tomp2> whats the programming area concerned with movable blocks connected by lines ( ie: chips and wires )? Is there something more specific than 'directed graph' ?
[15:43:40] <tomp2> cradek: does your G83 'tilt' the Z axis or maybe specify the abc angles?
[15:44:25] <tomp2> (does it translate the coord system )
[15:44:53] <cradek> tomp2: there is a new plane G17.1 (UV) which follows the tool around (W). These drill cycles are drilling "down" in W.
[15:45:09] <cradek> W is always aligned with the tool on this machine
[15:46:28] <tomp2> gotcha, i saw the vid, so W is what i thought was Z, but can lean in 'ZX'
[15:46:33] <tomp2> nice
[15:46:36] <alex_joni> cradek: wonder if you couldn't hijack UVW on a regular XYZABC machine for spatial circles..
[15:47:11] <cradek> Z is always perpendicular to the table. When there is a C axis finished, X and Y will actually rotate
[15:47:25] <cradek> and W is always the direction the tool's pointing
[15:49:01] <alex_joni> ok, then how about on a simple XYZ machine?
[15:50:23] <tomp2> got Z >and< W, didnt catch that, (cnc speak " W is always the direction the tool's pointing" skateboard speak "down is where your feet are")
[15:56:17] <cradek> tomp2: XYZ is the tooltip position in cartesian 'workpiece space'. BC define the tool direction. and yep W is "where the tool's feet are"
[15:56:43] <cradek> I hope to also have U,V where U is "in front of you" and V is "to the right" (the other tool coordinate directions)
[16:06:29] <alex_joni> geez.. these are quite expensive http://www.microkinetics.com/drivesub.htm
[16:07:29] <skunkworks> http://www.cnczone.com/forums/showthread.php?t=48266&highlight=microkinetics
[16:07:39] <rayh> Whatever happened to roll, pitch, and yaw.
[16:07:47] <SWPadnos> we threw them out
[16:07:50] <SWPadnos> :)
[16:07:56] <SWPadnos> w/we/chris/
[16:08:01] <alex_joni> rayh: can't use R as it's already used for radius
[16:08:11] <alex_joni> not sure RPW were ever used in rs274ngc
[16:08:18] <SWPadnos> P is also something
[16:08:22] <rayh> Yes it was.
[16:08:24] <SWPadnos> various things
[16:08:30] <cradek> you can write kinematics to control the machine however you want. The axes you have to work with are XYZABCUVW
[16:08:54] <rayh> There is an ordering to those words.
[16:09:53] <SWPadnos> I thought UVW were specified as parallel to XYZ respectively, but I didn't see that in the spec (I didn't look very hard, but I did look)
[16:10:09] <alex_joni> SWPadnos: no, I don't think that's correct
[16:10:23] <SWPadnos> secondary linear axes ...
[16:11:42] <rayh> We really have come quite far from the anything axis definitions as NIST had them
[16:12:07] <rayh> but then NIST never really completed the 6 or 9 axis interpreters.
[16:24:59] <tomp2> i think this is a (cartesian) convention: X, and rotating about X is A, and par to X is U, Y, and rotating about Y is B, par to Y is V, Z and rotating about Z is C, par to Z is W ( so the triplets are XAU YBV ZCW tho no one lists them in that order )
[16:36:25] <fenn> tomp2: it's called a block diagram
[17:00:50] <lewin1> lewin1 is now known as lewing_
[17:11:15] <tomp2> fenn: thx
[17:45:44] <BearPerson> * BearPerson kicks CIA-24
[17:45:44] <CIA-24> ow
[17:45:49] <BearPerson> hmm, at least that works. good.
[17:47:47] <JymmmEMC> SWPadnos: Got my BOB done yet?
[17:52:29] <SWPadnos> no
[17:53:50] <JymmmEMC> SWPadnos: Well, get the shit done already, what am I not paying you for?!
[17:56:02] <SWPadnos> nothing
[20:44:56] <CIA-24> 03jmkasunich 07TRUNK * 10infrastructure/farm-scripts/results_cia: removed some leftover code
[20:46:38] <CIA-24> 03jmkasunich 07TRUNK * 10infrastructure/farm-scripts/results_list: removed some more leftover code
[21:35:44] <JymmmEMC> SWPadnos: are ya done yet?
[21:35:53] <SWPadnos> yep
[21:36:04] <JymmmEMC> cool, lets see the pic
[21:36:08] <SWPadnos> what did you want again? :)
[21:36:24] <JymmmEMC> SWPadnos: turn that 20lbs of lead into gold
[21:36:55] <JymmmEMC> Did you know they really can do that now
[21:37:53] <JymmmEMC> Just the cost TO do that, far exceeds the amount of gold produced.
[21:40:00] <SWPadnos> well, that doesn't sound like a good business to be in then
[21:43:31] <skunkworks> an plus - the gold would be radio active
[21:43:49] <skunkworks> radioactive
[23:04:32] <alex_joni> jepler: talking meat? http://www.dailyhaha.com/_pics/meathead.jpg
