[00:00:36] <andypugh> danimal_laptop: I like the picture for the tiny welding torch which uses hypodermic needles for nozzles: https://picasaweb.google.com/doltonsjewellers/Workshop#5032587453469365410
[00:01:22] <danimal_laptop> ha thats cool, welding in miniature
[00:03:07] <macpod> I have added a button that runs a ncg subroutine. When I click the button, it says cannot find <a> is a.ngc and is located in /home/mill/emc2/nc_files/

[00:03:36] <macpod> I have this line

[00:04:17] <macpod> SUBROUTINE_PATH = /home/mill/emc2/nc_files
[00:04:34] <macpod> When I click the button, it says "Unable to open file <a>
[00:04:39] <macpod> thoughts?
[00:05:42] -!- theorb has quit [Read error: Operation timed out]
[00:05:43] <macpod> I copied one of seb_kuzminsky 's routines so the syntax should be good.. and the path seems ok. I don't think this is a permissions problem
[00:06:39] <andypugh> I am not sure that button clicks (is this an MDI_COMMAND) use SUBROUTINE_PATH, I think they use PROGRAM_PREFIX from [DISPLY]
[00:07:06] <macpod> This is an MDI_COMMAND, yes. I'll try that

[00:07:34] <macpod> I'm going off that
[00:07:35] <andypugh> Also note that everything gets lowercased and de-spaced

[00:08:04] <danimal_laptop> yea, quit yelling at me

[00:09:10] <andypugh> SUBROUTINE_PATH only works at all in v2.5 and above.
[00:09:36] <macpod> Ah, You are correct. Placing it in the prefix dir made it work

[00:17:26] <ve7it> JT-Shop, you around? looking for threading ideas and wondered if you have seen a threading helper app like some of the gcode generators
[00:19:23] <andypugh> ve7it: For a lathe?
[00:22:55] <JT-Shop> ve7it: I use ngcgui for threading
[00:23:50] <JT-Shop> I get a new water heater for xmas :/
[00:25:10] <macpod> Is it possible to use an absolute path in an MDI_COMMAND? It seems I could.. but I then need to specify the full path name in the o<...> sub stuff
[00:25:36] <macpod> Seems weird
[00:25:59] <andypugh> macpod: You shouldn't need to.
[00:26:13] <andypugh> But I haven't tried it.
[00:27:46] <macpod> If I have a path /home/stuff/file.nc, it doesn't seem to like "MDI_COMMAND = o</home/stuff/file.nc> call" if the sub section in file.nc is called "o<file> sub"
[00:28:18] <macpod> It finds the file, but complains it can't find the o
[00:28:35] <andypugh> Yeah, that sort-of makes sense
[00:28:37] <JT-Shop> macpod: prefix each line with G53 for machine coordinates if that is what your asking
[00:28:51] -!- robh__ has quit [Ping timeout: 252 seconds]
[00:29:02] <andypugh> JT-Shop: He is talking file-path, not cutter path
[00:29:09] <ve7it> JT-Shop, ok... I wondered if that did threading..... I need to extend the existing threads on a 1/2-13nc SS bolt by 1.25"... this means syncing machine to existing threads... kind of intimidating for a first threading project
[00:29:10] <JT-Shop> from that directory in a terminal window say pwm
[00:29:12] <JT-Shop> I think
[00:29:37] <andypugh> Ah, JT, just as I was logging off last night you said something about the Ballista?
[00:30:03] <andypugh> pwd? (rather than pwm?)
[00:30:25] <JT-Shop> Andy, yes it did well and as you suspected the the Z bent part did straighten out just a bit
[00:30:30] <JT-Shop> and yea pwd
[00:31:06] <JT-Shop> ve7it: you can sync the threads if you start the threading and turn the spindle by hand
[00:31:14] <macpod> Hmm, if I put o</home/stuff/file> sub and respective subcall, I get an error"File ended with no percent sign or program end" Guess I can't do that :D
[00:31:52] <andypugh> ve7it: Do a 0.577 thread in the air outside it first :-)
[00:32:08] <JT-Shop> macpod: it will be home/macpod/stuff/file or something like that
[00:32:23] <macpod> The path is correct. That was just an example
[00:32:32] <JT-Shop> ah ok
[00:32:44] <andypugh> macpod: I take it you are trying to keep you ngcfiles directory tidy?
[00:33:01] <macpod> yes, I'm ocd
[00:33:16] <macpod> I'm running 2.4.6 and wanted to keep my prefix directory set as the desktop
[00:33:37] <macpod> but I wanted to keep my nc file to home my machine in /home/<user>/emc2/nc_files
[00:33:42] <JT-Shop> if your using 2.4 everything has to be in the nc_files directory or where ever you said it was
[00:33:46] <andypugh> Well, sounds like you have a reason to upgrade to 2.5 then
[00:33:58] <macpod> Is it stable?
[00:34:11] <andypugh> In what sense?
[00:34:26] <JT-Shop> extremely stable just waiting on the doc people :/
[00:34:27] <ve7it> thanks guys, I'll see what ngcgui looks like..... I was not sure if I should build up code using g33 or g76
[00:34:33] <andypugh> It isn't going to change a lot, and it has been perfectly usable for over a year.
[00:34:41] <JT-Shop> ve7it: g76
[00:34:59] <macpod> in the sense of I'm new to cnc stuff, and I want to make sure bugs are because of me and not emc2 :D
[00:35:12] <macpod> Otherwise I won't know the difference and will always think it's me
[00:35:47] <JT-Shop> ve7it: http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=40&id=6355
[00:36:13] <andypugh> ve7it: You might also want to have a look at http://www.bodgesoc.org/lathe/lathe.html which is an alternative to ngcgui (but which I intend to re-hash a lot too)
[00:36:46] <andypugh> ngcgui is probably better.
[00:37:25] <andypugh> I rather want to make a parametric thread routine, where you give pitch and OD and it does the rest.
[00:38:36] <JT-Shop> kinda what I did but using TPI instead of pitch
[00:38:51] <JT-Shop> only calculation missing is thread depth, I think

[00:42:09] -!- sumpfralle [sumpfralle!~lars@31-16-115-146-dynip.superkabel.de] has joined #emc
[00:42:33] <andypugh> Yes, thread depth was the calculation I wanted to do.
[00:42:54] <andypugh> (I only use metric, so it is fairly straightforward, in theory)
[00:43:22] <andypugh> The problems come from touching-off profiled tools, which incorporate the root-rounding.
[00:43:26] <JT-Shop> yea, I did my first metric thread yesterday
[00:43:32] <JT-Shop> yep
[00:43:56] <JT-Shop> so if you know the tool tip radius you can calculate it all
[00:45:00] * JT-Shop wanders inside to cook some Amish noodles for dinner
[00:50:02] <danimal_laptop> without electricity i hope
[00:51:41] <andypugh> The main change I want to make to my macros is explicit internal/external threads. I hate it when my current macro guesses wrong...
[00:51:50] <Loetmichel> and his computer is based on steamdriven mirrors and kerosene lamps... ;-)
[00:52:04] <macpod> and 12v batteries
[00:52:13] <macpod> apparently those are OK
[00:52:23] <macpod> as are led lights run off batteries
[00:52:27] <andypugh> But not 6V ones?
[00:52:50] <Loetmichel> are they?
[00:52:59] <Loetmichel> how very not consequent ;-)
[00:53:28] -!- acemi has quit [Quit: WeeChat 0.3.2]
[00:53:40] <macpod> I don't know. I met someone who makes light figures that run off 12v car batteries for the amish. He charges them with heat from a fire (but no moving parts)
[00:54:45] <Loetmichel> (no, i have no problems with amish, i think their beliefs are a bit "outdatet" but thats MY opinion, if they want to live that way: let them)

[00:55:10] <macpod> badum-tish
[00:55:19] <Loetmichel> macpod: Thermocouples?
[00:55:35] <macpod> Thermocouples measure temp
[00:55:44] <Loetmichel> wrong ;-)
[00:56:00] <macpod> ok, you're right
[00:56:18] <Loetmichel> thermocouples generate voltage/current based on temperature difference
[00:56:29] <macpod> yea, but a barely useable one
[00:56:35] <Loetmichel> ... which is occasionally used for measuring Temperatures ;-)
[00:56:45] <macpod> this had to do with the effect that starts with a p
[00:56:52] <Loetmichel> macpod: thats a question of "plenty"
[00:56:54] <macpod> and those things that get hot on one side and cold on the other
[00:57:12] <andypugh> macpod: I think that their objection to electricity is that it comes in from outside.
[00:57:26] <macpod> There is a non-amish market that uses them to power fans to blow hot air for stoves out into the room
[00:57:35] <Loetmichel> a Peltier is nothing other dann a few hundred/thousand TC connected in series/parralel
[00:57:48] <andypugh> You an use the thermoelectric effect to make power.
[00:57:54] <macpod> yea
[00:58:06] <ds3> it is such an efficient process
[00:58:16] <andypugh> macpod: The Stirling Cycle fans make a lot more sense for that
[00:58:36] <Loetmichel> ds3; ~3-5% IIRC
[00:58:37] <Loetmichel> ;-)
[00:59:01] <macpod> I wonder if they can use solar panels
[00:59:01] <andypugh> http://partem.net/d.asp?product=VULCANSTOVEFAN
[00:59:45] <Loetmichel> macpod:: thats somethin which came instantly to my mind the moment you said "charges them with fire"
[01:00:58] <andypugh> macpod: Yes, it seems that they can use solar power, but prefer not to: http://www.shawcreekgeneralstore.com/amish_article1.htm
[01:01:13] <macpod> huh, strange

[01:04:25] <andypugh> At least they don't argue that they live the way they do because God told them to.
[01:06:02] <DaViruz_> why do they live the way they do?
[01:06:15] <andypugh> Because they want to. it seems.
[01:08:10] <andypugh> It is religious in nature, but it sees that they choose a lifestyle on the basis of its godliness, without claiming that the actual rules are divinely revealed. This is in contrast to the muslims and catholics, who do claim that the rules come straight from God.

[01:30:06] <DaViruz_> oh, that forum post actually was a FSM reference, i missed that
[01:34:51] <Danimal_garage> hmm time to do the control pannel layout
[01:35:09] <Danimal_garage> i think i'm actually going to trim down these enclosures a few inches

[01:43:43] <JaegerBar> Danimal did you get any offers on it yet?
[01:44:55] <Danimal_garage> $1700
[01:47:40] <Danimal_garage> and 17 virgins
[01:47:41] <Tom_itx> bidding war?
[01:48:14] <Danimal_garage> yea, pretty insane
[01:48:28] <Tom_itx> dude better step up his game
[01:48:40] <Danimal_garage> even a Nigerian prince wants it
[01:48:54] <Danimal_garage> he's willing to pay double too
[01:49:15] <Tom_itx> maybe he'll finance your whole op
[01:49:35] <Danimal_garage> gee, perhaps
[01:50:03] <Danimal_garage> should i just give him the deed to my house for collateral?
[01:50:38] <JaegerBar> lol
[01:50:56] <Tom_itx> you should have taken it the other day
[01:51:00] <Tom_itx> when it was 1k
[01:51:03] <JaegerBar> rofl
[01:51:20] <JaegerBar> back when you were gonna bid $1200 on it?
[01:51:32] <JaegerBar> and back when i wanted to pawn off my scooter on him
[01:51:49] <JaegerBar> i doubt i will get his router table
[01:51:57] <JaegerBar> some smart guy on craigslist is gonna nab it
[01:52:17] <Danimal_garage> i thought you had an endless budget?
[01:52:26] <JaegerBar> lol who said that
[01:52:30] <Tom_itx> you did
[01:52:34] <Tom_itx> like 20k or so
[01:52:34] <Danimal_garage> you
[01:52:44] <JaegerBar> no i said i wanted to spend $5k for everything
[01:52:59] <JaegerBar> but that included a mill as well as a router and tooling
[01:53:01] <Danimal_garage> well this is only 1k, you're way ahead of the game
[01:53:26] <JaegerBar> i hope you sell it for $1500 man
[01:53:55] <JaegerBar> just lemme know what people offer you on CL
[01:54:23] <Danimal_garage> the price is 1k, i dont see what it matters what people offer me
[01:54:42] <Danimal_garage> i'd rather smash it with a hammer than give it away
[01:54:45] <JaegerBar> it does matter, because next you're going to subtract out another item secretly
[01:55:05] <JaegerBar> first it's the 5i20, next it'll be some unknown part lol
[01:55:13] <Danimal_garage> another? i told you from day one it didnt come with the 5i20
[01:55:18] <Tom_itx> the 5i20 is a new board
[01:55:21] <JaegerBar> oh i guess i wasn't reading carefully
[01:55:39] <Tom_itx> never was on the table
[01:56:00] <Danimal_garage> i'm offering it for 1500 with the 5i20 because it's easier to order another one than explain to CL people what they need
[01:56:10] <JaegerBar> k
[01:56:21] <JaegerBar> just making sure man
[01:56:45] <JaegerBar> i didn't record the chat from before but i swore you said $1k for "everything you need to make it work"
[01:57:12] <Danimal_garage> i said the 5i20 is not included
[01:57:20] <JaegerBar> k
[01:57:22] <Danimal_garage> regardless, it's not
[01:57:57] <JaegerBar> well can you perhaps dilineate at some point what *IS* included
[01:58:10] <JaegerBar> is the computer related stuff included, for instance?
[01:58:29] <JaegerBar> like not just the tower but monitor, and any special hookup cable
[01:58:51] <JaegerBar> i just want to know so i don't get the stuff subtracted out later for not knowing
[01:59:13] <JaegerBar> i've had that happen to me before when buying a bike
[01:59:50] <Danimal_garage> the machine as you see it, the computer, the mesa 7i37 and 7i33, and i guess i can throw in the monitor and keyboard/mouse
[01:59:51] <JaegerBar> we agreed on the price, but when i go to buy it, he takes off the kickstand and gives me a different wheelset
[02:00:29] <JaegerBar> what about the cable that connects the 5i20 to the router?
[02:00:35] <Danimal_garage> no 5i20, no ribbon cables ($5 each from Fry's)
[02:00:40] <Tom_itx> you're not buying from another kid
[02:00:41] <JaegerBar> k
[02:00:51] <JaegerBar> shhhh Tom
[02:00:52] <Danimal_garage> thats it
[02:01:00] <JaegerBar> alright......cool
[02:01:12] <JaegerBar> i'll get back to ya next week if you haven't sold it
[02:01:16] <Danimal_garage> and no i wont trade for your hot wheels collection
[02:01:21] <Danimal_garage> :)
[02:01:24] <JaegerBar> lol
[02:01:34] <JaegerBar> what about micro machines?
[02:01:39] <Tom_itx> you don't make up your mind pretty quick i'll fly out and get it myself just to end this
[02:01:50] <Danimal_garage> lol Tom_itx
[02:01:52] <JaegerBar> sure Tom
[02:02:03] <Danimal_garage> JaegerBar: their spokesman was a meth addict
[02:02:03] <Tom_itx> you callin my bluff?
[02:02:14] <JaegerBar> i'll even buy you some beer from my favorite microbrewery
[02:02:24] <Danimal_garage> budweiser
[02:02:31] <Danimal_garage> is not a microbrewery
[02:02:39] <JaegerBar> you drink that stuff?
[02:02:46] <Danimal_garage> no
[02:03:11] <Danimal_garage> pbr if i'm slumming it, otherwise usually stone
[02:04:01] <JaegerBar> have you tried the green flash brewery over there in mira mesa
[02:05:08] <Danimal_garage> i tried it when it was in vista
[02:05:24] <Danimal_garage> its ok
[02:05:31] <Danimal_garage> mother earth is a little better
[02:05:39] <Danimal_garage> lost abbey too
[02:05:44] <JaegerBar> someone told me green flash split off from stone
[02:16:39] <JaegerBar> so danimal, do you happen to know the make of that router table? been looking all over for it

[02:34:05] <mrsun> hmm, on screwless vices, does the jaw move at all when tightening the bolt ?
[02:34:36] <macpod> screwless? like a toolmaker's vice?
[02:34:45] <macpod> If so, yes
[02:34:55] -!- ries has quit [Quit: ries]
[02:35:20] <macpod> but the screw keeps the block down on the table so it doesn't tilt the workpiece
[02:35:26] <mrsun> yes ... never used one so =)
[02:35:43] -!- JaegerBar has quit [Quit: ChatZilla 0.9.87 [Firefox 8.0.1/20111120135848]]
[02:35:44] <mrsun> so it moves it both in and down then
[02:35:46] <mrsun> down i figured
[02:35:51] <macpod> Right
[02:36:01] <mrsun> holding it down that is, but in seems like it would have a hard time doing due to friction etc =)
[02:36:26] <macpod> The bolt is connected in the center of a dowel for lack of a better word
[02:37:08] <macpod> you position that dowel in different slots underneath the vices sliding area according to what size your work piece is
[02:39:57] <mrsun> mm figured =)
[02:43:58] <macpod> damn, I just had a bad string of luck
[02:44:16] <macpod> I turned around and what I was cooking caught on fire
[02:44:25] <macpod> on a frying pan
[02:44:56] <macpod> so I put a cap on it and turned off the heat, but then some bacon grease dripped out and it flamed up again
[02:45:13] <macpod> so my kitchen filled with smoke and set off the smoke detector
[02:45:32] <macpod> I ran the pan out to my balcony and closed the door behind me so I don't set off the buildings detector
[02:45:44] <macpod> when I closed the door, the bar fell down and I couldn't get back in
[02:46:04] <macpod> I also had to put the pot down and burn the carpeting out there to hell
[02:46:28] <macpod> ended up climbing down 3 balconies and luckily I didn't lock my front door
[02:46:34] <macpod> all barefoot.. aww yea
[02:49:03] <mrsun> omg
[02:49:25] <mrsun> and back to irc fast as hell to tell the story ? :P
[02:49:41] <macpod> I'm waiting for the pot to cool so I can toss it
[02:49:52] <macpod> It's got burnt bacon reminants and carpet stuck to it haha
[02:50:48] <mrsun> time to try and sleep again
[02:50:57] <mrsun> dog wanted out 2 hours ago ....
[02:51:05] <mrsun> and i cant sleep if i have to get up :/
[02:53:37] <Danimal_garage> that sucks
[02:53:58] <Danimal_garage> i guess im pretty lucky i have 2 dogs with huge bladders
[02:54:22] <Danimal_garage> they can hold it for 15 hours or so

[04:47:13] <danimal_laptop> i think i successfully shortened the enclosure for my control pannel.
[04:47:25] <danimal_laptop> and got the cutout for the monitor finished
[04:47:47] <danimal_laptop> just gotta poke a few holes in it for some buttons and the mpg then i can powdercoat it
[04:56:02] <Tom_itx> cool
[04:56:21] <Tom_itx> just swapped out the power jack on a laptop
[04:59:48] <danimal_laptop> sounds like fun
[04:59:59] <Tom_itx> yeah

[05:00:57] <danimal_laptop> i just have radio shack soldering irons lol
[05:01:06] <danimal_laptop> like a $10 one
[05:01:16] <Tom_itx> i have 2 of those bureied in the bottom of my toolbox with bad tips
[05:01:30] <Tom_itx> one lasted me a day
[05:02:50] <danimal_laptop> lol
[05:03:04] <Tom_itx> i've got a decent weller
[05:03:04] <danimal_laptop> i just hit them on the belt sander every once in a while
[05:03:16] <Tom_itx> same tip i've had for years
[05:03:24] <danimal_laptop> it helps if you loosen and retighten them too
[05:03:41] <danimal_laptop> my shitty iron is a few years old at least
[05:03:52] <danimal_laptop> same tip as well
[05:05:12] <danimal_laptop> my dog is so weird, she runs to the bowl, grabs a mouth full of food, and brings it to her bed to eat it. then repeats until she's full.
[05:06:45] <danimal_laptop> this show is horrible (fringe).
[05:07:05] <danimal_laptop> i wish i had cable for that reason alone. it's all that's on

[17:40:48] <SWPadnos> skunkKandT, do you know what that guy means when he says you need to operate optos in the "MB region"?
[17:42:04] <skunkKandT> no.. I thought maybe 'not saturated..' (on the transistor side..)
[17:42:18] <skunkKandT> (yes I know that isn't 'MB'
[17:43:31] <pcw_home> If you have a OPTO coupled PWM --> analog converter you need Mb optos for good linearity
[17:43:51] -!- toastydeath has quit [Read error: Connection reset by peer]
[17:47:43] <pcw_home> But the discussion started out about PWM servo drives. In that case all the timing "servoed out" anyway so as long as you
[17:47:45] <pcw_home> dont have more than a couple % or so distortion its pretty much irrelevant
[17:47:47] <pcw_home> (also if you are worried about your spindle speed accuracy, close the loop with an encoder :-)
[17:48:51] <SWPadnos> do you mean "megabit" (as in high speed), or is Mb actually something else?
[17:50:17] <pcw_home> Yeah like the digiital 1 to 10 Mb/s isolators
[17:52:21] <pcw_home> Though I find the AD magnetic and TI capacitive isolators much better than any OPTO so only use OPTOS for cheapness nowadays
[17:53:08] <Loetmichel> hmm, i have some spare mini gbit FDDI tranceivers in the company...
[17:53:47] <Loetmichel> maybe i should make a opto board from them with a fiber bundle instead of a lpt cable?
[17:54:33] <pcw_home> You normally need to modulate the data with those (not DC coupled)
[17:54:39] <Loetmichel> i.e.: a little board with the tranceivers direcktly on the lpt port and then with a multi-Fiber-cable directly to the Machine ;-)
[17:54:51] <Loetmichel> pcw_home: they are dc coupled
[17:55:45] <Loetmichel> just a LD as a sender and a photo diode as a reciver and som signal driver/recovery electronics in them
[17:55:51] <pcw_home> Are you sure? usually the AGC on the receiver bails after a few usec of inactivity and you're dead
[17:56:11] <Loetmichel> iirc the datasheets yes
[17:56:27] <Loetmichel> they are dumb as a slice of bread
[17:57:40] <Loetmichel> but that wouldnt be a problem: take a 300Mhz quarz osc and a And/nand/nor at the sender and similar at the reciver to demodulate...-> BIngo ;-)
[17:58:05] <pcw_home> I doubt it, the recovery circut (Slicer) needs to set its thresholds to the peak amplitudes
[17:58:56] * Loetmichel s company had used them for baseband signal transfer out of tempest shielded equipment, to have something to compare the measurement
[17:59:11] <Loetmichel> so i am pretty shure they CAN do dc
[17:59:15] <Loetmichel> not pretty but OK
[17:59:58] <Loetmichel> (being build for square wave and fed with sines and such)
[18:00:48] <pcw_home> There are baseband fiber T/Rs but usually for very short or slow applications

[18:37:30] <Mjolinor> can someone give me a link to read about the format of the lines in the .hal file please
[18:37:40] <Mjolinor> http://www.linuxcnc.org/docs/devel/html/config/emc2hal.html
[18:37:53] <Mjolinor> I have that which is good so far but it doesn't explain the line format
[18:38:06] <Mjolinor> for example net mpg-a encoder.0.phase-A <= parport.1.pin-02-in
[18:38:41] <Mjolinor> 4 terms on the line, the last one is directed into the third one, no idea what hte first adn second terms are
[18:41:55] <pcw_home> mpg-a is the "wire" created by the command
[18:41:57] <pcw_home> encoder.0.phase-A is the wires destination
[18:41:58] <pcw_home> and parport.1.pin-02-in is the source
[18:42:22] <pcw_home> the <= is just for looks
[18:42:32] <Mjolinor> yup, but I want to knwo the format
[18:42:59] <Mjolinor> I want to start at the bottom and eg create a file that I can run with halrun that makes ab output pin track an input pin
[18:43:15] <Mjolinor> I want to start at the bottom and eg create a file that I can run with halrun that makes an output pin track an input pin
[18:43:45] <pcw_home> wire sink,sink, sink (...) source
[18:45:52] <Mjolinor> ok, so: newsig defines a name, I can then do things with that name like "linksp" to attach it to soemthing
[18:46:31] <Mjolinor> so there has to be a page soemwhere that defines the things that go in the first term
[18:46:55] <Mjolinor> net addf linksp newsig and so on
[18:51:02] <pcw_home> I think the net command creates them
[18:52:27] <Mjolinor> I think newsig creates them :)
[18:52:53] <Mjolinor> a document would be nice
[18:57:08] <pcw_home> It also looks like the sink/source can be in any order (as long as you only have one source)
[18:57:43] <Mjolinor> you reckon that => doesnt mean anything?
[18:57:51] <Mjolinor> I thought it was hte direction
[18:58:03] <Mjolinor> you get <=, => and <=>
[18:58:30] <Mjolinor> pretty damn noodle baking it is :)
[19:01:08] <pcw_home> No the arrows are for clarity but not needed
[19:02:49] <Mjolinor> ok
[19:02:55] <pcw_home> The parser knows the pin directions so doesn't need any hints
[19:05:41] <pcw_home> Dont know if newsig/linkps,linksp are deprecated but it does not seem to be used much anymore (since I think net can do all the same things)

[20:19:25] <alex4nder-> slckaer
[20:19:33] <JaegerBar> is that a CNC gantry router?
[20:19:42] <Loetmichel> ... eating a pizza ;-)
[20:19:49] <Loetmichel> not gantry
[20:20:03] <alex4nder-> JaegerBar: did you break the piggy bank and by danimal_laptop's machine?
[20:20:16] <JaegerBar> someone else is gonna get it
[20:20:18] <JaegerBar> it's ok
[20:20:35] <JaegerBar> i can't come up with the money till i sell some stock options
[20:21:02] <JaegerBar> how big is that router Loet? like 500 Watt?
[20:21:06] <alex4nder-> selling options eh
[20:21:10] <alex4nder-> that's pretty meta
[20:21:37] <Loetmichel> JaegerBar: the on milling: 400W
[20:21:43] <Loetmichel> and max 5000 rpm
[20:22:00] <JaegerBar> selling options?
[20:22:02] <Loetmichel> the one the machine makes the clamps for: 800W ;-)
[20:22:08] <JaegerBar> no i mean like company stock options
[20:22:26] <JaegerBar> you know like working at a tech company they give you stock optoins
[20:22:33] <JaegerBar> and then you gotta go to ETrade to redeem them
[20:22:58] <alex4nder-> yah like coupons at the supermarket
[20:24:38] <JaegerBar> sorta
[20:24:50] <JaegerBar> it's an annoying way to be compensated
[20:25:04] <alex4nder-> or like a newegg rebate
[20:25:07] <Loetmichel> hmm... sounds like SAP or IBM...
[20:25:08] <JaegerBar> because you're always waiting to redeem, hoping the price of the stock goes higher
[20:25:33] <Loetmichel> dont see it as compensation
[20:25:38] <alex4nder-> yah, it isn't
[20:25:53] <alex4nder-> it's a way for companies to entice you, without taking real risk.
[20:25:54] <mrsun> 8x22 angular contact is the smallest i can find but they are quite expensive :/
[20:25:56] <Loetmichel> see it as "workforce binding to the company"
[20:26:13] <alex4nder-> Loetmichel: I see you've worked for a tech company before. ;
[20:26:15] <alex4nder-> )
[20:26:30] <Loetmichel> not me.
[20:26:33] <Loetmichel> my wife does
[20:26:53] <alex4nder-> ah
[20:26:57] <alex4nder-> close enough
[20:26:58] <JaegerBar> you work for a tech company
[20:27:07] <JaegerBar> isn't that tempest protection pretty techie
[20:27:16] <Loetmichel> yes, but no big one
[20:27:18] <Loetmichel> ;-)
[20:28:10] <Loetmichel> i have three workers left which report to me, and the company is only about 8 or 10 ppl (depends if you count the part time hands in)
[20:29:19] <JaegerBar> those small companies are the best
[20:29:23] <JaegerBar> no stress hahaha
[20:29:56] <mrsun> hmm, how can a thrust bearing not be both ways? :P
[20:30:39] <Loetmichel> but i have to say: my exexexex boss at the Stage rental was better at binding and motivating the workers. He was quick-tempered, but always the first to come to the venue, the last to go and the hardest worker of them all
[20:31:02] <Loetmichel> JaegerBar: no stress?!? DREAMER!
[20:31:12] <JaegerBar> sorry
[20:31:30] <alex4nder-> mrsun: is that a philosophical question?
[20:32:22] <mrsun> alex4nder-, no bearing boys divides thrust bearings into single direction and double direction :P
[20:32:33] <mrsun> http://www.bearingboys.co.uk/Thrust_Ball_Bearing-3411-c
[20:33:41] <alex4nder-> yah? that's pretty reasonable
[20:33:52] <Loetmichel> on my business car is written: "Production manager" ... my job is: Production manager, shrink for the boss/wife, purchase dep., development dep., customer relations, lecturing the apprentice and of course any work the others cant do/wont be in time...
[20:34:12] <Loetmichel> card
[20:34:17] <alex4nder-> haha
[20:34:22] <JaegerBar> do you ever yell at your apprentice
[20:34:25] <alex4nder-> Loetmichel: the beauty if being in a small bsuiness
[20:34:26] <Loetmichel> no
[20:35:21] <alex4nder-> yah, I just threaten my interns with having to be stuck taking out the trash instead of working on cool stuff
[20:35:25] <alex4nder-> and they usually shape right up
[20:35:40] <Loetmichel> JaegerBar: i had luck: the apprentice is a sart young boy, very capable and no more lazy than i am, so we work best together ;-)
[20:36:06] <Loetmichel> smart
[20:36:08] <JaegerBar> i wish i was that apprentice
[20:38:50] <JaegerBar> how old is your apprentice?
[20:38:55] <JaegerBar> 19?
[20:39:55] <toastydeath> i had a very interesting apprentice period, I got along well with the grumpy old guys
[20:39:59] <Loetmichel> he has about half a year left 'til is end tests. i treat hil like a full worker and say " do this and that, if you dont know how: ask!"
[20:40:06] <Loetmichel> that is working for me
[20:40:40] <JaegerBar> you're an awesome manager
[20:41:25] <Loetmichel> and he makes phptps of me like this one when he catches me at somethin "not quite up to code" -> http://www.cyrom.org/palbum/main.php?g2_itemId=12244

[20:41:57] <Loetmichel> ( i said i am lazy sometimes?)
[20:42:11] <alex4nder-> JaegerBar: oh, I asked TechShop about machining steel.. they don't have a problem with it
[20:42:21] <alex4nder-> so I don't know who told you that you can't machine steel on their equipment
[20:43:51] <Loetmichel> (the white bottle is ethanol 99% and the paper is drenched with it ;-)

[20:49:11] <mrsun> ahh ok
[20:49:22] <Loetmichel> if i am not mistaken by the english: yes
[20:49:36] <Jymmm> i thought you should use two of them - one per end
[20:51:13] <Loetmichel> Jymmm: i learned to NEVER fix both ends of a axis
[20:51:47] <Jymmm> Well, that's true. Then yeah, you shoul dhave two on the same end, opposing directions iirc.
[20:52:03] <Loetmichel> ome end with a double thrust bearing, the other with play in the bearing so that it can move with temperature
[20:52:09] <Jymmm> so they "lock" the shaft in essense
[20:52:39] <Jymmm> Loetmichel: Yeah, that's what my routers X is - floating on one end
[20:53:00] <Jymmm> but no angular on the other end currently
[20:53:04] <Loetmichel> Jymmm: a two row angular contact bearing can be play free and can get thrust from both sides
[20:53:14] <Loetmichel> so it is ok to use one
[20:53:16] <Jymmm> ah
[20:53:23] <Jymmm> I'm speak of singles
[20:53:26] <Loetmichel> but depending on the manufactirer the CAN have some play
[20:53:29] <Jymmm> two singles
