Back
[00:00:21] <djdelorie> they have a max continuous (2.5 A for mine) and a max "for ten seconds" spec (7.5 A for mine)
[00:00:54] <Valen> djdelorie: you can probably go to 12A or so for shorter periods again
[00:01:00] <djdelorie> Valen: but servos do not need to pull max current when they're stopped, or moving slowly.
[00:01:14] <Valen> djdelorie: this much i know ;->
[00:01:17] * Valen has a servo machine
[00:01:24] <djdelorie> Valen: I let it do 8 amps for a fraction of a second, then limit to 2.5. It seems to have PLENTY of torque for my application
[00:01:46] <Valen> the "current limit" thing is more about temperature
[00:01:59] <djdelorie> the power supply is 2 amps continuous, but has lots of capacitors to handle the bursts
[00:02:08] <djdelorie> and to absorb the braking current
[00:02:27] <Valen> the "best" method is to monitor the temp of the motor for long term feedback, and limit the short term stuff with a model of the heat created inside the motor
[00:03:10] <djdelorie> If I were to do something like that, I'm more likely to monitor the temperature of my driver chip
[00:03:29] <Valen> seperate issue
[00:03:36] <Valen> driver chip will cool off quickly
[00:03:38] <Valen> motors less so
[00:03:49] <djdelorie> yeah, but my power supply is already "too small" for the three motors, despite the machine working just fine
[00:04:16] <eric_unterhausen> which power chip did you use?
[00:04:18] <Valen> so pushing the motor + driver combo hard for a while then stopping for 10 secs and punching it again the driver chip has plenty of thermal room, the motor less so
[00:04:22] <djdelorie> I *can* monitor the power supply voltage, though, and limit current if the voltage starts dropping.
[00:04:24] <r00t4rd3d> looks like your motors came out of a washing machine
[00:04:28] <Valen> djdelorie: everything is a compromise
[00:04:32] <djdelorie> FNB41560
[00:04:37] <Valen> lower current limit = lower acceleration
[00:04:46] <Valen> if your happy with that then thats fine
[00:04:50] <djdelorie> Valen: yup. This machine was "get something working, make a better one later"
[00:05:12] <r00t4rd3d> i bought this power supply today:
[00:05:12] <r00t4rd3d> http://www.ebay.com/itm/120674032390?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[00:05:21] <djdelorie> and the acceleration is already more than my plywood machine can handle anyway :-)
[00:05:30] <Valen> hah plywood!
[00:05:31] <Valen> ;-P
[00:05:43] <djdelorie> see the photos URL I posted above ;-)
[00:06:08] <Valen> r00t4rd3d: we have a pair of 12v ones of those running our mill
[00:06:16] <Valen> after ~2 years one of them is starting to die
[00:06:23] <djdelorie> r00t4rd3d: you can see my two power supplies here:
http://www.delorie.com/photos/cnc/img_2519.html
[00:06:50] <r00t4rd3d> valen the power supply your talking about?
[00:06:58] <Valen> yes
[00:07:00] <djdelorie> the switcher runs the logic and gate drives, the monster linear runs the motors
[00:07:50] <r00t4rd3d> I have a giant pile of parts
[00:11:20] <r00t4rd3d> im not even sure on my design yet
[00:13:41] <r00t4rd3d> http://alansmachineworks.com/images/CNC_Router/CNCRouter2x3MDF%28c%29.JPG
[00:13:47] <r00t4rd3d> http://wardscorner.net/images/CNC/rockcliff02.jpg
[00:14:41] <r00t4rd3d> now tell me something, the top image and the gantry I think its called moves back and forth and in the second pic the table moves back and forth. Whats better?
[00:17:09] <djdelorie> "gantry moves" is more complex, but takes up less space for the same size work area
[00:17:26] <djdelorie> imagine trying to move a sheet of plywood back and forth...
[00:18:31] <djdelorie> but for pcb mill/drill, a moving table might be more precise since the gantry is fixed
[00:23:45] <r00t4rd3d> http://www.cnccookbook.com/img/OthersProjects/Machines/KTCNCFinal024.jpg
[00:23:52] <r00t4rd3d> wish I could just afford that
[00:25:09] <r00t4rd3d> the guy makes water cooling for his video cards with it lol
[00:25:09] <djdelorie> if wishes were wings, frogs wouldn't bump their asses on the ground when they hopped
[00:25:14] <r00t4rd3d> http://www.cnccookbook.com/img/OthersProjects/Machines/DevilWC1.jpg
[00:25:24] <r00t4rd3d> http://www.cnccookbook.com/img/OthersProjects/Machines/DevilWC2.jpg
[00:27:06] <r00t4rd3d> Water cooling scares me. One wrong dip and its all over.
[00:45:10] <Tecan> wife's scare me
[00:45:59] <r00t4rd3d> are you gay?
[00:51:01] <Jymmm> r00t4rd3d: Why, are you asking him for a date?
[01:08:10] <r00t4rd3d> I was trying to set you up.
[02:00:10] <DJ9DJ> moin
[02:29:27] <Loetmichel> mornin'
[02:29:44] <DanteTDI> hi Loetmichel
[06:00:33] <jthornton> archivist, www.mysidewheeler.com/boiler.htm
[06:13:08] <archivist> bah "thread-o-lets" threaded bush !
[06:19:53] <archivist> a far more serious boiler
[06:20:56] <jthornton> what do you think of the design of that one?
[06:26:23] <archivist> design looks ok, regulations may vary on available internal inspection, lower large threaded bush may be his
http://www.mysidewheeler.com/1942%20finish.JPG
[06:27:11] <archivist> in the uk we often have taper plugs screwed in at washout and inspection
[06:28:53] <archivist> see bottom corner and middle
http://www.middleton-leawood.org.uk/leawood/images/boilerhouse/photo1.html
[06:29:30] <archivist> also on larger ones a man hole of some sort
[06:29:30] <jthornton> the two pipe plugs
[06:29:54] <archivist> yes but there are a lot more than two
[06:31:53] <archivist> each boiler type needs different ways to inspect probable wear points
[06:32:32] <archivist> US boiler code lags behind UK as far as I know
[06:35:19] <archivist> this was a prime example
http://www.nytimes.com/2001/07/30/us/steam-engine-blast-at-ohio-fairgrounds-leaves-4-men-dead.html
[06:35:38] <archivist> just not possible in the UK
[06:37:56] <jthornton> what wears out in the boiler?
[06:37:56] <archivist> http://steamtraction.farmcollector.com/steam-engines/final-report-tragedy-medina-county-fairgrounds.aspx
[06:38:20] <archivist> read that second link, will give some clues
[06:39:50] <archivist> erosion not just corrosion where there are the right conditions
[06:39:51] <jthornton> ok
[06:44:13] <archivist> over here mobile boilers (traction engines and rail locomotives) get stripped every 7 years iirc, static boilers are 10year but often people do 7 to keep safe
[06:45:31] <jthornton> that one just sounds like the old guy was not too smart but smart enough to blow up his boiler
[06:46:08] <archivist> that and the lack of inspection allowed it to get that bad
[06:46:51] <archivist> we cannot get insurance for public display without the proper inspection
[06:50:44] <jthornton> does this link work for you
http://www.pmresearchinc.com/
[06:51:34] <jthornton> I might talk my buddy Ray into scaling down his quest for a steam engine to a model sized one
[06:54:01] <Jymmm> ridable model?
[06:54:39] <jthornton> he wants to build a steam powered boat...
[06:55:28] <Jymmm> at least its not a luxury liner
[06:58:29] <archivist> ! go for a launch engine moooore fun
[06:58:58] <archivist> stupid site that one has to "enter"
http://www.pmresearchinc.com/store/home.php?cat=3
[06:59:08] <jthornton> http://www.pmresearchinc.com/store/product.php?productid=3093&cat=4&page=1
[07:02:45] <archivist> build that as well
[07:03:22] <archivist> I should finish the models I have started :)
[07:03:44] <archivist> I need to go shopping else no lunch
[07:03:49] <jthornton> the model looks like a good first steam project
[07:03:55] <jthornton> ok thanks
[07:08:58] <Tecan> mornin
[07:10:20] <jthornton> that it is
[07:11:01] <jthornton> and a lovely one at that
[07:12:04] <archivist> with your machine tools it wont take long :)
[07:14:54] <Jymmm> I think a steam powered cannon mover would be a better choice
[07:15:12] <jthornton> a steam powered tugger
[07:15:25] <Loetmichel> soo, modified a existing heatsink (
http://www.cyrom.org/palbum/main.php?g2_itemId=11573 ) to fit the L297/L298 board and crossover airflow... ->
http://www.cyrom.org/palbum/main.php?g2_itemId=13077
[07:16:19] <Loetmichel> ... i will mount the complete electronics before doing the x and z axis because its sowed away INSIDE the Mill Bottom plate.
[07:16:25] <Jymmm> Is there such a thing as an alcohol engine?
[07:17:08] <Jymmm> burns 100% alcohol?
[07:18:23] <jthornton> internal combustion engine?
[07:18:49] <Loetmichel> Jymmm: ANY benzine engine can trun with Alcohol
[07:20:48] <Jymmm> I thought I heard once that there's something a bit different than a typical internal combustion engine
[07:21:24] <jthornton> well you need bigger jets on the carb to run alcohol
[07:22:04] <Jymmm> why bigger?
[07:22:10] <TekniQue> there are fuel cells that burn alcohol too
[07:22:48] <Jymmm> TekniQue: Actually "burn" alcohol, or "use" alcohol?
[07:23:08] <jthornton> because alcohol burns at a different mixture with air than gas
[07:24:07] <Jymmm> jthornton: I thought it would burner leaner? So would need smaller jets
[07:24:12] <jthornton> that's why you get less miles to the gallon burning E85
[07:24:16] <Jymmm> s//burner/burn/
[07:24:50] <jthornton> nope bigger jets are fitted for alcohol
[07:25:24] <Jymmm> and for propane?
[07:25:39] <Jymmm> or NG
[07:27:02] <jthornton> each one is a bit different, I forget if propane or NG has more energy per unit
[07:27:51] <Jymmm> k. I've just seen a kit that can turn my gasoline generator into tri-fuel... Gas/LPG/NG
[07:28:11] <jthornton> when I installed my central air I had to put a propane conversion kit (a different orifice size jet) in the gas heater
[07:28:57] <TekniQue> Jymmm: I'm not sure about the exact chemistry of those cells
[07:29:08] <Jymmm> TekniQue: np, thanks =)
[07:29:23] <TekniQue> but you need bigger jets for alcohol in an internal combustion engine
[07:29:38] <TekniQue> the reason is that alcohol contains less energy per gram than petrol
[07:30:00] <Jymmm> really? I would have thought more.
[07:30:02] <TekniQue> and has a lower specific oxygen requirement
[07:30:03] <TekniQue> nope
[07:30:09] <TekniQue> much less
[07:30:35] <Loetmichel> propane has 20% less energy per liter than 95ROZ
[07:30:38] <Loetmichel> 30%
[07:30:48] <Loetmichel> alcohol ~20% iirc
[07:30:56] <TekniQue> it's about 30% for ethanol
[07:31:00] <TekniQue> 50% for methanol
[07:31:16] <Jymmm> But alcohol burns so damn hot!
[07:31:24] <Loetmichel> TekniQue: per liter or per gramm?
[07:31:35] <Loetmichel> Jymmm: that depends on mixture
[07:32:10] <Loetmichel> with alcohol you want to be a bit on the fat side otherwise there will be a hole in the Aluminium piston ;-)
[07:32:21] <Jymmm> I can boil 8oz of water 3x faster using alcohol than I can using a petrolium product
[07:32:38] <TekniQue> Loetmichel: per volume
[07:33:12] <Loetmichel> TekniQue: my Opel Astra has run with E85 with about 20% less MPG than with 95/98ROZ
[07:33:30] <TekniQue> yeah, E85 is still 15% petrol
[07:33:41] <Loetmichel> i know
[07:33:59] <TekniQue> I have no experience with alcohol in street driven cars though
[07:34:06] <Loetmichel> but that would only account for 5% or so of the mog
[07:34:06] <TekniQue> only used it on racing cars
[07:34:08] <Loetmichel> mpg
[07:34:21] <TekniQue> and it needs such a big fat load of it
[07:34:58] <Loetmichel> and someone stated that the astra SOULDNT be run full load for longer periods of time because the fuel burns hotter if you dont modify the jets
[07:35:06] <Jymmm> Does alcohol fubar an engines overall life?
[07:35:10] <Loetmichel> and one can ruin the engine this way
[07:35:14] <TekniQue> Loetmichel: yes
[07:35:29] <Loetmichel> Jymmm: no, if you are careful not to floor it permanently not
[07:35:53] <TekniQue> Jymmm: it has some properties that are not ideal for engine life
[07:35:53] <Loetmichel> the opposite is true: alcohol burns cleaner AND is a better solvent,
[07:35:59] <TekniQue> others that are good
[07:36:10] <Loetmichel> the jets and fuel lines were clean as new as i scrapped the astra
[07:36:10] <TekniQue> it burns very clean so it doesn't leave much deposits in the engine
[07:36:20] <TekniQue> pistons stay shiny et al
[07:36:21] <Jymmm> Loetmichel: so a lower duty cycle is prefered when using alcohol?
[07:36:42] <TekniQue> but the alcohol has worse evaporative properties
[07:36:58] <Loetmichel> (cause i had hit a wild hog @ 50mph)
[07:37:02] <TekniQue> and the engine needs to burn much more of it
[07:37:14] <TekniQue> which hurts the lubrication of the cylinder walls
[07:37:19] <TekniQue> especially when the engine is cold
[07:37:56] <Loetmichel> another problem with E85 in an unmodified engine: starting properties tend to go wores, especially in winter ;-)
[07:38:00] <Loetmichel> worse
[07:38:18] <TekniQue> yes, because the alcohol is not evaporating well
[07:38:24] <Jymmm> Heh, alcohol dont like cold
[07:38:41] <Jymmm> 40F and it whines
[07:38:56] <TekniQue> on the dragsters, it's not unusal to squirt some petrol down the air inlet before starting
[07:39:14] <Loetmichel> hmmm
[07:39:14] <TekniQue> when running 100% methanol
[07:39:16] <Jymmm> TekniQue: No problem, just take a torch to heat up the alcohol
[07:39:30] <TekniQue> I've not had problems starting on 100% ethanol
[07:39:42] <Loetmichel> petrol is 95/98ROZ benzine in english?
[07:39:47] <TekniQue> but I've never tried to below 15°C
[07:39:50] <Jymmm> TekniQue: how cold does it get in the winter?
[07:39:51] <TekniQue> Loetmichel: yes
[07:39:55] <Loetmichel> wahts "petroleum" (Jet-a1) then?
[07:40:01] <TekniQue> Loetmichel: kerosene
[07:40:11] <TekniQue> jet a1 = kerosene in english
[07:40:22] <Loetmichel> sorry, meant the stuff in the lamps, not the jet fuel
[07:40:28] <TekniQue> it's the same stuff
[07:40:39] <Loetmichel> (even its more or less the same stuff) ;-)
[07:40:54] <TekniQue> lamp fuel and jet fuel from my local petroleum company is the exact same stuff
[07:41:00] <Loetmichel> i know
[07:41:47] <Loetmichel> whats the german "super" (98/100ROz) called in english?
[07:41:49] <Loetmichel> premium?
[07:42:03] <TekniQue> depends on the marketing department I suppose
[07:42:10] <TekniQue> premium is common
[07:42:15] <TekniQue> or super
[07:42:16] <Jymmm> Loetmichel: racing fuel?
[07:42:31] <Loetmichel> Jymmm: no, normal fuel in germany
[07:42:45] <Loetmichel> 95ROZ isnt aviable over here any more
[07:42:47] <TekniQue> Jymmm: no racing fuel is the stuff that comes in drums, smells like roses and costs 4 euros/litre
[07:43:27] <Jymmm> Loetmichel: There's one gas station here that does sell 112 octane racing fuel at $8/gallon, compared to $4/gallon for 85 octane
[07:43:29] <Loetmichel> just 98ROZ ("super"), 100++ROZ ("super plus") and E10.
[07:43:46] <TekniQue> Loetmichel: really?
[07:43:46] <Jymmm> WOOHOO!!!
[07:43:50] <Loetmichel> And diesel of course (and "super diesel")
[07:43:54] <TekniQue> I thought it was the other way around
[07:43:56] <Loetmichel> TekniQue: really
[07:44:06] <Jymmm> FINALLY a useful purpose for tofu!
http://www.jsonline.com/business/29419454.html
[07:44:06] <TekniQue> I've had trouble finding 98 in europe
[07:44:12] <TekniQue> in some parts at least
[07:44:14] <TekniQue> only 95
[07:44:42] <Jymmm> 83/87/92 is common in US
[07:44:52] <TekniQue> Jymmm: yes but the scales are different
[07:45:01] <TekniQue> the euro companies advertise the RON number
[07:45:15] <Jymmm> k
[07:45:17] <TekniQue> the american companies advertise the (RON+MON)/2
[07:45:41] <TekniQue> 95RON by german standards at least is 91 octane by the american standard
[07:45:47] <TekniQue> and 98 = 93
[07:46:03] <TekniQue> I think the american system is a bit strange
[07:46:22] <TekniQue> it's absolutely stupid that you have pumps that sell 5 different grades of gasoline
[07:46:32] <Loetmichel> ... and on some gas stations you will find LPG and/or E85
[07:46:33] <TekniQue> 83, 87, 89, 91, 93
[07:46:39] <TekniQue> but no diesel
[07:46:47] <Loetmichel> ... btw: what is a gallon in liters?
[07:46:55] <Jymmm> 4
[07:46:57] <Jymmm> roughy
[07:47:00] <TekniQue> * 3.7854118
[07:47:00] <TekniQue> / 0.26417205
[07:47:01] <Loetmichel> $8/gallon sounds cheap to me
[07:47:18] <Loetmichel> ouch, you dont want to have our prices
[07:47:34] <Jymmm> nope
[07:47:46] <Loetmichel> E10 is 1.680Eur /LITER at the moment
[07:48:27] <Jymmm> TekniQue: Not every places sells LPG either
[07:48:50] <Loetmichel> and diesel is 1.60Eur /l atm
[07:48:52] <archivist> that is not a real gallon Jymmm its a short changed usa sized one
[07:49:02] <Loetmichel> aehm, 150Eur/l
[07:49:12] <Loetmichel> grrr
[07:49:13] <Jymmm> Now a days, it's retail stores that offer full tank exchange instead.
[07:49:17] <Loetmichel> 1.50Eur
[07:49:19] <TekniQue> true, the brits have a bigger gallon
[07:49:59] <Jymmm> and by "Full" they mean 75% full in fine print.
[07:50:07] <TekniQue> * 4.5460993
[07:50:07] <TekniQue> / 0.2199688
[07:50:09] <Loetmichel> just have filled my car um a few weeks ago...
[07:50:10] <Jymmm> big lawsuit
[07:50:12] <TekniQue> this is british gallon
[07:50:25] <Loetmichel> http://www.spritmonitor.de/de/detailansicht/442560.html
[07:50:38] <Loetmichel> any questions on diesel prices in germany?
[07:56:04] <jthornton> archivist,
http://john-tom.com/html/ElmersEngines.html
[07:58:51] * Loetmichel would like to build a micro turbine for ethanol... and a make a 100W genset from it ;-)
[07:59:06] <Loetmichel> but my machines are no good for cutting iconel
[07:59:37] <Jymmm> Why NiChrome?
[07:59:44] <Jymmm> rust?
[08:01:03] <Loetmichel> temperature
[08:01:08] <Jymmm> ah
[08:02:21] <Loetmichel> the "hot" side of a turbine disk is just below yellow hot... not good for normal steel ;-)
[08:02:56] <Loetmichel> and (depending on size) 60kRPM to 300kRPM (!) fast ;-)
[08:03:04] <TekniQue> yeah you need something like inconel at temperatures like that
[08:05:06] <Loetmichel> the compressor side can be made from aluminium
[08:06:03] <Tecan> it puts the lotion on its elbows
[08:08:26] <Spida> Loetmichel:
http://www.gtba.co.uk/
[08:11:11] <Loetmichel> Spida: way to big
[08:11:29] <Loetmichel> i need about 100.. 200 Watts shaft power
[08:11:47] <Loetmichel> and maximum 300 grams for the whole engine, tank and generator ;-)
[08:12:13] <Loetmichel> should power a quadcopter "on the fly" ;-)
[08:15:33] <mazafaka1> wheels, winch or diff lockers, in which order to buy?
[08:36:49] <WillenCMD> Good morning!
[08:39:02] <archivist> jthornton, you should have one of those little ones made in a day...or six...or more with cnc programming :)
[08:40:08] <WillenCMD> http://www.wemotec.net/products/controller-modules/WT-SC25-Servocontroller.html does anybody know anything about this?
[08:42:42] * archivist never seen it before and hates "price on request", analog/pwm input should be compatible
[08:44:14] <JT-Shop> archivist: it will take longer than that to program it LOL
[08:44:54] <archivist> was "estimate" :)
[08:45:12] <archivist> not counting beer and nap time
[08:45:57] <WillenCMD> Price on request is how everything works, i can't stand it
[08:46:17] <WillenCMD> you inquire about more info and price, they email you back with more info and no price
[08:46:18] <JT-Shop> yea, you gotta take beer/wine and naps into account
[08:46:44] <WillenCMD> then you ask for a price, they email back with qty and still NO PRICE
[08:47:18] <archivist> email back no price-NO SALE
[08:47:36] <WillenCMD> finally after about 10 emails, you can get a price. Come to find out its way out of budget and i wasted my time
[08:48:20] <WillenCMD> just an example of everyday business, in the world of automation
[08:54:20] <Loetmichel> WillenCMD: i've seen that also
[08:55:40] <Loetmichel> only approbiate reaction: tell the dealer that you bought a competitor product for him not telling you how cheap/expensive his is.
[08:58:04] <WillenCMD> ya thats basically what i do
[08:58:47] <Loetmichel> <- upgrade to linxCNC2.5... lets see if the Machine is operational afterwards ;-)
[08:58:58] <Loetmichel> s/ upgrade / upgrading
[09:23:22] <Spida> Loetmichel: what kind of quadcopter do you want to power? for how long?
[09:31:47] <DJ9DJ> hi syyl
[09:32:57] <archivist> nice engineers level in uk fleabay 160783333214 /me has one and its larger brother
[09:41:55] <WillenCMD> can anyone give me a good starting point for designing a custom screen?
[09:42:03] <WillenCMD> should i just modify one of the available ones
[09:45:43] <Loetmichel> Spida: as long as it goes
[09:45:55] <Loetmichel> and a small one with 1kg TOW
[10:02:40] <Spida> Loetmichel: 200W (electric) will barely be enough for a 1kg copter
[10:02:58] <Loetmichel> Spida: wrong
[10:03:16] <Loetmichel> will be the double of the "hovering power"
[10:04:09] <Spida> Loetmichel: ok, assuming 200W (eletric) is enough, you will need more than 200W on the shaft to generate 200W electric
[10:04:27] <Loetmichel> power peaks up to the 1200W the motors can draw max will be provided by a slamm lifepo battery
[10:04:28] <Spida> Loetmichel: you will not find a generator with 100% efficiency and zero weight *g*
[10:04:44] <Loetmichel> hovering power is ~100W
[10:05:36] <Spida> Loetmichel: so you want to carry a fuel tank, a turbine, a generator, and a battery that can deliver peak-currents, and some charging-logic for the battery?
[10:05:54] <Loetmichel> Spida: a brushless outrunner motor with ~300W will have a efficiency of about 80% with fast rectivier diodes
[10:06:06] <Loetmichel> right
[10:07:39] <Loetmichel> already tested thar
[10:07:41] <Loetmichel> that
[10:07:46] <Spida> Loetmichel: assuming you know the energy/weight for a battery and for your fuel of choice, you can calculate how much your turbine/generator/battery set may weight for a given amount of total stored energy. did you make this calculation?
[10:08:18] <Loetmichel> no, why should i?
[10:08:35] <Loetmichel> that will be "calculated" experimentally
[10:08:59] <Loetmichel> i dont know the efficiency of a selfbuild turbine so i cant calculate it beforehand
[10:09:45] <Loetmichel> amd for the charging circuit: that is just a modified esc
[10:10:51] <Loetmichel> with 6 fast recovery diodes reverse over the fets (bodydiodes are to slow) and a software which can measure the DC voltage and can output a signal to choke the turbine/engine
[10:11:21] <Loetmichel> BTDT but with a 6,5 ccm glow engine and a 12V lead acid battery
[10:11:44] <Loetmichel> as a byproduct the brushless can be used as a starter for the engine/turbine
[10:16:20] <Loetmichel> btw: i am amazed: upgraded to 2.5... loaded the old config in stepconf, executed it, startet linuxcnc: tuns like never was an older version in the machine ;.)
[10:34:15] <ReadError> mister joe9
[10:34:17] <ReadError> you around?
[11:06:48] <skunkKandT> http://emc2arduino.wordpress.com/
[11:08:40] <awallin> skunkKandT: and the technical advantages of doing that are??
[11:09:50] <bedah> great.. making a new blog about emc and linux, right after emc is officially named linuxcnc XD
[11:10:02] <bedah> -linux+arduino
[11:10:44] <skunkKandT> very little.. thinking it might be a good reference.. I don't know how he is doing the stepping but it sounds like it is pretty slwo
[11:11:05] <bedah> http://www.markuskayser.com/work/solar-sinter/ this thing is using an arduino, too
[11:11:25] <skunkKandT> *slow
[11:13:54] <skunkKandT> huh - it looks like he sends it the commanded position - that is it.
[11:14:40] <JT-Shop> I did a wordpress page once and got a zillion bot comments so I deleted it ASAP
[11:15:10] <isssy> and the idea is??? to stay in the deserd at 40 degree celsiut all day to get what?? :-D
[11:15:30] * JT-Shop thinks it is nap time
[11:16:08] <Tecan> its not naptime till the fat lady sings
[11:16:11] * Tom_itx just finished mowing and wholeheartedly agrees
[11:16:28] <awallin> JT-Shop: akismet works well for blocking spam
[11:23:48] <r00t4rd3d> I wonder where I can get 3/8 ID bearings locally
[11:23:59] <r00t4rd3d> do skateboard shops have those?
[11:24:38] <r00t4rd3d> or harbor freight
[11:31:57] <Tecan> in my settings what would cause my mill to render everything backwards on the x axis ?
[11:32:09] <Tecan> nm its flipped in the y
[11:32:41] <Tecan> nm found it
[11:34:41] <skunkKandT> Tecan: did you get your laser rastering?

http://mechmo.de/styrocat.html
[11:41:25] <IchGuckLive> i did that reprograming today
[11:41:57] <ve7it> seems to be working in Canada
[11:42:05] <IchGuckLive> B)
[11:42:11] <joe9> ReadError: what's up?
[11:42:20] <ve7it> very nice foam cutter
[11:42:40] <IchGuckLive> Thanks ve7it
[11:43:46] <ReadError> joe9
[11:43:50] <ReadError> my mill shipped
[11:43:55] <ReadError> wondering how long it took yours
[11:44:00] <ReadError> since we about in the same area
[11:44:06] <IchGuckLive> READERROR is a bad nickname i thoudt now its not able at joe9 O.O
[11:44:11] <joe9> from a2z?
[11:44:21] <ReadError> arizona
[11:44:40] <ReadError> direct from taig
[11:44:49] <joe9> from a2z, they shipped on Fri and I got it on Wed.
[11:44:53] <ReadError> a2z kinda screwed me ;(
[11:45:00] <ReadError> where does a2z ship from?
[11:45:01] <joe9> ReadError: what did a2z do?
[11:45:02] <DJ9DJ> IchGuckLive, the impreint page layout seems to be broken ;)
[11:45:07] <Tecan> i cant fix it... how do i invert the y axis
[11:45:08] <DJ9DJ> *imprint
[11:45:13] <ReadError> joe9: well i ordered these handles they had on ebay
[11:45:19] <ReadError> said instock: 2
[11:45:22] <ReadError> wait a week
[11:45:32] <ReadError> they call me and say "oh hai, we cant get these for a month"
[11:45:55] <joe9> ReadError: a2z did a similar thing to me. said they were shipping on wed, but, they did not ship till Fri.
[11:45:58] <ReadError> why list something as 2 instock and then tell me you dont have them?
[11:46:15] <IchGuckLive> DJ9DJ: i need to check this in trunslation impreint
[11:46:27] <ReadError> come in 2 boxes?
[11:46:44] <ReadError> i got 2 tracking #'
[11:46:55] <ReadError> but UPS has no weight/delivery estimate ;(
[11:48:14] <IchGuckLive> impressum -> imprint
[11:48:26] <joe9> yes, 2 boxes.

[11:49:02] <DJ9DJ> this is what it looks like in my firefox 12.0
[11:49:17] <DJ9DJ> i think the page layout at the end of the page is not what you expected
[11:49:38] <IchGuckLive> DJ9DJ: Thanks are you on 800x600
[11:50:01] <DJ9DJ> nope, i cropped the picture... the screen has 1900x1280
[11:50:24] <IchGuckLive> Thanks i will overlook this one moment
[11:50:47] <DJ9DJ> i just removed the white space at the left and right and also the browser icons / bookmarks
[11:53:37] <DJ9DJ> oh, the screen resolution is 1920x1080 (full hd)
[11:54:18] <DJ9DJ> but its the same on 1400x1050 ;)
[11:54:19] <IchGuckLive> Dj is the vertical menue on all sites disordert at VORICHTUNGSBAU
[11:55:29] <DJ9DJ> IchGuckLive: yes, at least for me, its on all pages the same
[11:55:43] <IchGuckLive> let me giv it 5more px
[11:55:49] <DJ9DJ> >> [line break] Vorichtungsbau
[11:56:02] <Tecan> setp axis.2.homed 1 << why would this not work ?
[11:56:09] <Tecan> says that pin is not writable
[11:56:28] <DJ9DJ> IchGuckLive, better now :)
[11:56:40] <IchGuckLive> its up
[11:56:51] <DJ9DJ> i see :)
[11:57:31] <DJ9DJ> looks good now. everything is ok
[11:57:40] <IchGuckLive> imprint also
[11:57:44] <DJ9DJ> yep
[11:57:53] <IchGuckLive> ok thank you

[11:58:06] <IchGuckLive> B) O.O ;-)
[11:58:13] <DJ9DJ> no problem :)
[11:58:28] <IchGuckLive> so 5px made my day
[11:59:05] <IchGuckLive> im off for today
[11:59:16] <IchGuckLive> BY
[11:59:22] <DJ9DJ> bye
[11:59:27] <DJ9DJ> to fast for me ;)
[11:59:31] <DJ9DJ> +o
[11:59:41] <SWPadnos> Tecan, that pin is an output telling the rest of the world that the axis has been homed, not an input that tells the axis that it is at home
[11:59:56] <SWPadnos> or that it needs to do a homing sequence
[12:01:36] <Tecan> what happens when you invert the xstep ?
[12:01:41] <Tecan> not the dir
[12:02:09] <SWPadnos> it just changes whether a step is logic high or logic low on the output pin
[12:02:28] <SWPadnos> internally, a step is a positive pulse
[12:02:44] <SWPadnos> if it needs to be a negative pulse externally, invert the output
[12:03:08] <Tecan> like when i print something the y axis is flipped upside down
[12:03:25] <SWPadnos> in that case invert the dir output
[12:03:33] <ReadError> joe9: you know any scrap yards in ATL where i could obtain some aluminum?
[12:18:50] <alex4nder> yoh
[12:23:20] <ReadError> alex4nder: IT SHIPPED!
[12:23:28] <ReadError> from mesa, az
[12:23:52] <ReadError> i need tool plate, some clamps, 1-2-3 block, machinist square
[12:23:54] <ReadError> i think..
[12:24:06] <ReadError> anything im missing?\
[12:25:04] <alex4nder> I'd get real t-slot nuts, ditch the tooling plate for now, and get a dial test indicator, and some touch off tools from Fisher Machine
[12:29:41] <ReadError> but i wont have anything to hold stuff down ?
[12:29:49] <ReadError> or just use the clamps on the stock bed
[12:30:04] <alex4nder> the table has slots, the t-nuts go in the slots
[12:30:23] <alex4nder> you'll get some with the taig, but they're super cheese ball
[12:35:11] <ReadError> i dont want to tear up my stock table being a n00b
[12:35:39] <ReadError> thats my big worry
[12:39:58] <alex4nder> ReadError: well your mill is going to get scratched up eventually.. a new table for it is $135.
[12:40:23] <joe9> ReadError check with ssi. he knows more about the area than I do.
[12:40:41] <joe9> and, do not forget to stop by HarborFreight for some cheap stuff.
[12:40:55] <joe9> and, they have pretty good coupons/sales most of the time.
[12:41:58] <ReadError> can i use a pair of 1-2-3 blocks+t-slot nuts as a vice?
[12:42:04] <ReadError> or would i be better with some clamps
[12:42:27] <alex4nder> you'll want some clamps
[12:42:40] <ReadError> 2 or 4?
[12:43:55] <alex4nder> I have 12 of them in different sizes
[12:44:04] <alex4nder> I like kant-twist
[12:44:20] <alex4nder> what's the first thing you're going to make?
[12:44:55] <ReadError> oh nice, they have one on my way home and they are open til 9!
[12:44:56] <Tom_itx> chips
[12:45:05] <ReadError> alex4nder: some motor mounts probably
[12:45:16] <ReadError> basically a piece of aluminum with some holes
[12:45:26] <alex4nder> for a car?
[12:45:48] <ReadError> nah
[12:45:52] <ReadError> small electric motors
[12:45:54] <alex4nder> ah
[12:46:17] <alex4nder> if I were you'd I'd think about how you're going to mill those, then think about how to fixture them, then buy the tools required to fixture them
[12:46:20] <alex4nder> then .. profit.
[12:46:29] <ReadError> http://a248.e.akamai.net/origin-cdn.volusion.com/lctho.wfrjz/v/vspfiles/photos/MTRMOUNT-01-2.jpg?1316040753
[12:46:32] <ReadError> something like that
[12:46:41] <alex4nder> ah
[12:46:51] <ReadError> 2.5d basically
[12:46:53] <alex4nder> that looks like less than 1/4" thick
[12:46:55] <alex4nder> right?
[12:47:01] <ReadError> oh for sure
[12:47:13] <alex4nder> you don't need anything, you can do that using what comes with the mill
[12:48:24] <alex4nder> they're sending you the collets, vise, and the small endmills right?
[12:48:33] <alex4nder> as part of the starter package
[12:49:23] <ReadError> yea basic CR package
[12:50:24] <alex4nder> yah, I think you could mill that without needing anything special
[12:50:29] <alex4nder> although a machinist square would be nice
[12:51:31] <ReadError> yea
[12:51:40] <ReadError> gonna order one from amazon today
[12:53:37] <ReadError> and i need some lube too
[12:54:00] <alex4nder> eh, it comes good to go
[12:54:25] <alex4nder> unlike the chinese mills
[12:54:47] <awallin> ReadError: what mill did you get?
[12:54:54] <ReadError> taig 2019cr
[13:00:12] <WillenCMD1> does anyone know where to start when it comes to developing a custom screen? should i just edit one thats made... or start from scratch
[13:06:25] <archivist> WillenCMD1, we dont know why you want to, what languages you can program....looking at gui's that are already written will start you off
[13:10:07] <awallin> WillenCMD1: pyvcp or gladevcp should have examples in the manuals... if you just want some add-ons to e.g. AXIS
[13:11:59] <psha> WillenCMD1: try extending axis/touchy with panels fist
[13:12:00] <psha> first
[13:12:57] <mozmck> anyone here tried lxde for a desktop?
[13:15:00] <skunkKandT> how come you always ruin the part when trying to silver solder.. or is that just me?
[13:15:10] <skunkKandT> *first part
[13:15:28] <cradek> mozmck: I recently tried whatever xubuntu-desktop in precise gives you
[13:15:42] <cradek> after some adjusting of preferences it's perfectly fine IMO
[13:16:32] <skunkKandT> I guess it just takes 1 try to know what not to do...
[13:16:43] <mozmck> cradek: that's xfce. I think it pretty good as well. I'm playing with lxde right now (you can get it with lubuntu-desktop). Some features are nicer than xfce or gnome2 even.
[13:17:23] <cradek> my only complaint was that I never found make-capslock-another-ctrl
[13:17:34] <mozmck> for instance, when you show hidden files in the file manager, it shows them in the main window but *not* in the tree (it's about time someone did this IMO!)
[13:18:25] <mozmck> I miss the tabs in xfce-terminal, and it also doesn't have an option to kill the default menu key (F10). LXterminal has both.
[13:18:38] <mozmck> I haven't used that so I don't know about it.
[13:18:45] <cradek> interesting
[13:19:00] <cradek> I don't use any file manager stuff, so can't compare their worths
[13:19:11] <cradek> also I never use terminal tabs, prefering to use screen in those cases
[13:19:14] <mozmck> LXDE is faster as well.
[13:19:18] <mozmck> screen?
[13:19:28] <cradek> screen!
[13:19:39] <cradek> aka "gnu screen"
[13:19:44] <archivist> skunkKandT, careful placement before you heat and stuff around propping bits likely to fall/bend/whatever
[13:19:49] <mozmck> The file manager also has tabs which the xfce file manager is missing. I use those a lot.
[13:20:01] <mozmck> haven't used gnu screen...
[13:20:39] <cradek> I use it all day every day :-)
[13:20:58] <mozmck> I guess it uses hotkeys to switch between virtual terminals?
[13:21:16] <cradek> yes, and scrollback and copy/paste and persistence when you disconnect
[13:21:40] <cradek> I can't imagine life without it
[13:21:56] <skunkKandT> archivist: This was mainly a - silver didn't wick the way we thought it would..
[13:22:55] <mozmck> Basically the same as tabs I guess. I hit Alt+(tab number) to switch tabs. Each one is the same as having multiple terminal windows open.
[13:23:35] <cradek> but can you disconnect, leaving all the "tabs" going, and later pull them up from another terminal somewhere? or your phone? that's what's awesome about screen.
[13:23:36] <mozmck> try LXDE - you'll probably like it. You can install it with the afore-mentioned package - and it was only about 50 or 60 meg download.
[13:24:10] <mozmck> Nope! but I haven't had to do that yet. I'll have to look at it.
[13:24:10] <cradek> my irc client is inside screen
[13:42:34] <Tecan> is there a way to scale something once in axis ?
[13:43:15] <cradek> do you mean scale the gcode? no
[13:48:47] <JT-Shop> interestingly my old Anilam control can scale, rotate and a few other tricks, but is it a PIA to use the OI
[13:49:09] * JT-Shop goes back to making a pair of understraps
[13:49:48] <archivist> methinks gcode prompts for values would be a valid thing
[13:50:20] <JT-Shop> ngcgui does that for me
[13:50:21] <joe9> i tried screen but felt it was slower.
[13:50:42] <joe9> there seemed a latency between pressing the key on the keyboard and it showing up on the terminal
[13:50:48] <archivist> but just as easy to design scaling into the gcode prog and edit it
[13:53:36] <JT-Shop> yea like some of the sample code does
[14:00:21] <archivist> my gear progs have a set of variables like no of teeth length of cut etc
[14:04:54] <strykerg> psha you there?
[14:08:01] <strykerg> anyone with some experience on hooking up webcams with camunits ?
[14:09:01] <JT-Shop> archivist: you should be able to make the worlds smallest steam engine with your tools :-)
[14:09:41] <archivist> JT-Shop, I think some nuts have already been there done that
[14:11:38] <archivist> JT-Shop, think of the ink jet in your printer that pumps out a pico litre ish
[14:12:22] <djdelorie> Tecan: you could change your gearing ratios in the .ini, to make it *think* it's doing the original size...
[14:13:11] <cradek> you'll mess up your velocities and accelerations
[14:18:08] <joe9> is there something I can take from an old dot matrix printer that can help me with cnc stuff?
[14:20:29] <ReadError> joe9: cut anything yet or still trying to get the switches working?
[14:24:45] <archivist> often dot matrix printer internals are on the cheap and just enough to do the job, I tend only to use as a source of rods to machine
[14:32:37] <psha> strykerg: little bit
[14:48:10] <Cra_> Hi guys, someone was on here last night using a brushless dc motor as a spindle like I do...are you or anyone else using a dc motor and ESC ?
[14:48:19] <Cra_> ..about, that is!
[14:49:06] <Thetawaves> what kind of steel is 'plain' steel
[14:49:08] <ReadError> why not use a router?
[14:49:20] <ReadError> or a dremel ?
[14:50:33] <Thetawaves> wtf kind of steel is this www.crownbolt.com/Products/ProductList.aspx?Type=T3&Cat=C20&SubCat=S110&Part=20150
[14:53:32] <Cra_> ReadError.. was that to me?
[14:53:39] <Cra_> If it was, too big. My machine is TINY!
[14:54:39] <archivist> Thetawaves, mild steel, rough shite, black iron
[14:55:16] <Thetawaves> yeah
[14:55:43] <Thetawaves> i'm trying to determine the magnetic permeability so i might use it as a core in one of my coils.
[14:55:50] <Thetawaves> if only there was a number!
[14:56:33] <archivist> you want a soft iron(silicon iron) for magnetics
[14:57:06] <Thetawaves> got an easy source?
[14:58:02] <archivist> er sheet comes from old motors and transformers, short rod from solenoids
[14:58:27] <Thetawaves> i probably should buy some kind of kit or something with a design guide so i can really do the maths before building/testing a coil
[14:59:03] <Thetawaves> the problem with those materials is that they so easily saturate
[14:59:04] <archivist> or you can use iron powder/ferrite core
[14:59:13] <Thetawaves> because they were designed to run at 60hz when i want to do ~5khz
[14:59:36] <archivist> ferrite then
[14:59:59] <ReadError> Cra_
[15:00:04] <ReadError> you can use the flex handle
[15:00:17] <Thetawaves> archivist, so you think it would be good to look around for some ferrite cores
[15:00:44] <Cra_> Can you guys lend some advice - simple electronics questions but it really isn`t my thing so I`m stuck!! I`m powering my motor with a 12v supply. I`m powering my Breakout board with a 24v supply. I`m having my breakout board send a signal to my spindle driver and for it to detect a reference to the signal I need to ground the spindle driver from the breakout board supply!
[15:00:59] <archivist> Thetawaves, yes /me would look in his stock
[15:01:07] <Cra_> so then I`ve crossed grounds on both supplies....how do I check they are both at a common ground and there is no pd!!??
[15:01:52] <Thetawaves> if the grounds are crossed, how can they not be at the same level?
[15:01:57] <Tom_itx> use a common ground
[15:02:09] <Tom_itx> and check them with a meter
[15:02:23] <Tom_itx> ground is at zero potential
[15:02:28] <Cra_> how do I use a common ground? ... sorry, I presume this is an obvious answer
[15:02:31] <Thetawaves> archivist, i don't have much in the way of coils... relatively new area for me
[15:02:31] <Tom_itx> all else is referenced from that
[15:03:07] <archivist> Thetawaves, I have some stock from a transformer company that shut down
[15:03:07] <Tom_itx> Cra_, it is the point at which you measure your 12 and 24v from
[15:04:21] <Cra_> You see in my knowledgless mind, I have a black ground from each supply. But for this job, I`m going to end up connecting the ground of one supply to the ground of the other but I believe this is when things go pop or bang, if there is a small pd across them and they are not at the same pd!
[15:05:55] <archivist> Cra_, if the supplies are isolated from mains(have a transformer internally) then there cannot be that small pd to create a problem
[15:06:29] <Cra_> they are both ATX pc supplies that I`ve jumped so they run without the PC....does that sound ok?
[15:07:06] <archivist> they are switchers and do have isolation
[15:07:41] <Cra_> so that is good? so I can connect away to my hearts content without any fears?!
[15:08:17] <Tom_itx> live with fear but do it anyway
[15:08:23] <Cra_> lol
[15:08:35] <archivist> yes black to black, report smoke
[15:08:40] <Cra_> I`ll be on here crying if my computer gors pop with it
[15:09:02] <Tom_itx> so use a meter and check your work
[15:09:20] <archivist> but...which side of the breakout are you supplying
[15:09:27] <Cra_> When I start prodding with my meter things tend to go pop as well!!
[15:10:29] <Cra_> OK, basically the ESC that runs my spindle needs a pwm signal. to make a reference to the pwm signal it needs a ground BUT it is already getting a ground from the other power supply.... in which case...it should already be grounded....OH FFS!
[15:11:09] <Tom_itx> make sure the 2 supplies share a common ground
[15:11:29] <Cra_> ???? I don`t really understand what that involves??
[15:11:31] <Cra_> sorry..
[15:11:40] <Tom_itx> wire
[15:11:49] <Cra_> ??
[15:11:54] <Tom_itx> and 2 grounds
[15:11:54] <Cra_> from and to ... ?
[15:11:55] <Tom_itx> run them together
[15:11:57] <archivist> joining the two psu black wires
[15:12:04] <Cra_> it is like painting by numbers with me :p
[15:12:12] <Cra_> ahh ...really??!?
[15:12:16] <Tom_itx> uh huh
[15:12:16] <archivist> black is 0v
[15:12:31] <Tom_itx> check it to be sure though
[15:12:41] <Tom_itx> you never know what knuclehead was in there
[15:12:44] <Cra_> "check it" ...
[15:13:00] <Jymmm> Cra_: Are you using PC or Switching power supplys?
[15:13:00] <archivist> your meter and some thinking
[15:13:17] <Cra_> I`m using ATX supplies that I`ve pulled out of old PCs.
[15:13:20] <archivist> Jymmm, PC supplies ARE switching
[15:13:39] <Jymmm> archivist: Yes, but does HE know that was the question.
[15:13:55] <archivist> Jymmm, its not relevant
[15:50:44] <Jymmm> Cra_: Know anyone on the bomb squad by chance? They have nice suits you can borrow
[15:50:55] <ReadError> anyone here anodize aluminum before?
[15:51:21] <Jymmm> whats his name in SD does
[15:51:48] <pfred1> I've melted aluminum
[15:51:52] <Tom_itx> danimal
[15:52:07] <Jymmm> Yeah, SAN
[15:52:12] <Jymmm> not SD
[15:52:43] <archivist> iirc danielfalk does too
[15:53:21] <Jymmm> pfred1: Uh, CONGRADULATIONS and/or Sorry to hear that, depending on the situation
[15:53:52] <Jymmm> which is the same when someone tells you their divorce is final.
[15:54:11] * pfred1 made beercanium
[15:54:34] <Jymmm> pfred1: now for Beearindacanium
[15:54:49] <archivist> I worked at an anodizing company 40 years ago does that count
[15:55:07] <ReadError> pfred1: how did that turn out?
[15:55:13] <pfred1> archivist I worked at a place that chromed printing dies
[15:55:22] <pfred1> ReadError pretty good
[15:55:40] <Jymmm> pfred1: what type of furnace / forge?
[15:56:08] <pfred1> a 5 gallon metal pail I put some fire bricks around
[15:56:10] <ThadiusB> finally got my wireless adapter to work on Ubuntu...yay! lol
[15:56:12] <archivist> I need a better flame before I melt ally again, mine was a fail
[15:56:15] <pfred1> I have a pic of it
[15:56:38] <pfred1> aluminum is so easy yo ucould do it on a barbeque if you blast it
[15:56:40] <Jymmm> pfred1: common pail, really?
[15:56:55] <pfred1> it had that roofing coating in it
[15:57:08] <pfred1> well that didn't last
[15:57:19] <pfred1> let me find a pic of my blast furnace
[15:57:29] <Thetawaves> pfred1, my favorite is "10 hour" bonfire
[15:57:41] <Jymmm> pfred1: Hmmm, ok. I thought something that thin wouldn't last too long
[15:57:46] <Thetawaves> if you can get close enough to it
[15:57:49] <pfred1> http://i.imgur.com/Ld6E4.jpg
[15:58:12] <Thetawaves> leet
[15:58:15] <Jymmm> ah, the devil cat furnace, gotcha
[15:58:30] <Thetawaves> awesome stand
[15:58:42] <pfred1> yeah we got all drunked up at a GP motocross race and melted a bunch of lawn chairs once
[15:58:44] <Thetawaves> do the tires get hot?
[15:59:00] <archivist> Iiznotneedmelting sez cat
[15:59:02] <pfred1> Thetawaves those are real firebricks
[15:59:15] <pfred1> like out of a kiln
[15:59:42] <pfred1> so no the outside of it doesn't really get hot
[15:59:50] <Jymmm> I saw the coolest little propane/60# gas tank dolly yesterday. Even had a tilt back too.
[16:00:02] <Jymmm> err 80#
[16:00:21] <pfred1> oh there is a really cool furnace setup where you have a foot pedal and half of it opens up
[16:00:50] <Jymmm> pfred1: is that before or after eyebrowsbegone?
[16:01:30] <ReadError> pfred1: is the product pretty solid?
[16:01:35] <ReadError> or does it break apart easy
[16:01:59] <Jymmm> dont you have to add coke or lime or something?
[16:02:12] <Jymmm> or is that just for gold?
[16:02:15] <pfred1> ReadError no it is solid cast aluminum
[16:02:48] <pfred1> you keep melting cans you end up with a pot of silver liquid and pour it
[16:03:41] * ReadError only drinks beer from bottles or kegs ;(
[16:03:43] <Jymmm> pfred1: did you add anything to it?
[16:03:54] <pfred1> no
[16:04:11] <pfred1> I might have tossed some borax on it it was a while ago
[16:04:23] <Jymmm> ah, ok.
[16:04:41] <pfred1> man gnash sucks
[16:05:24] <Jymmm> pfred1: When I play with fire, I'm more into purrrty lights than KaBooms or liquid solids =)
[16:06:02] <pfred1> it is a pain I do it outside so the weather has to be right
[16:06:17] <Jymmm> no shed or carport area?
[16:06:58] <pfred1> I have some outbuildings but I'm not into fires in buildings
[16:07:19] <Jymmm> ah, heh. I wasn't suggesting that at all
[16:07:38] <pfred1> when I'm blasting a flame comes out the top like a jet engine
[16:08:02] <Jymmm> pfred1: Got Marshmellows?
[16:08:13] <Jymmm> Hot Dog on a stick?
[16:08:17] <pfred1> if you did it'd go up like a sparkler
[16:08:27] <pfred1> poof
[16:08:37] <ReadError> pfred1: can you pour a block of aluminum?
[16:08:44] <pfred1> it is almost like a cutting torch
[16:08:44] <Jymmm> well, not THAT close =)
[16:08:47] <ReadError> i need to hit up the scrap yard
[16:08:51] <ReadError> find me some metal to learn on
[16:09:08] <pfred1> ReadError what kind of metal?
[16:09:13] <ReadError> aluminum
[16:09:17] <ReadError> dont care what type really
[16:09:27] <pfred1> the trick with cans is crush them first
[16:09:31] <ReadError> but no reason to buy new if im just 'derping' around
[16:09:35] <ReadError> the plastic burns out?
[16:09:50] <pfred1> then keep on pushing them into the pool of molten metal
[16:10:18] <pfred1> yeah you get a lot of dross with cans
[16:11:26] <Jymmm> pfred1: have/are you getting into making casts and such?
[16:11:40] <pfred1> so far all I've done is pour ingots
[16:11:40] <DJ9DJ> gn8
[16:11:43] <ThadiusB> how is everyone today?
[16:11:58] <pfred1> I want to pour a pulley for my homemade lathe
[16:12:10] <Jymmm> k
[16:12:27] <pfred1> I made a pattern and everything haven't made the boxes
[16:12:37] <pfred1> I might try lost foam and slurry
[16:12:43] <pfred1> that is really cool
[16:13:10] <pfred1> you make a foam form then dip it into thinned out sheetrock spackle a few times then put it into dry sand
[16:13:18] <Jymmm> pfred1: Yeah, you'll need to make a cnc hot wire foam cutter now =)
[16:13:25] <pfred1> no making greensand and ramming it
[16:13:47] <pfred1> though pouring it is kind of hectic because the foam burns off
[16:14:02] <Jymmm> metls instantly
[16:14:11] <pfred1> it flames out
[16:14:23] <Jymmm> no biggy
[16:14:35] <pfred1> molten aluminum is about 1250F
[16:15:09] <Jymmm> But foam is like 99% air, you only have this tiny amount of plastic liquid to burn off
[16:15:24] <pfred1> I guess I've seen videos
[16:16:02] <Jymmm> pfred1: when you build the cnc hot wire foam cutter, just dont use AC =)
[16:16:21] <pfred1> I wouldn't use hot wire
[16:16:38] <Jymmm> pfred1: It be silly not to
[16:17:21] <Jymmm> pfred1: it's uttely amazing at how precise you cna be with a HWFC
[16:18:00] <pfred1> I don't see it working out very well cutting V grooves for a pulley
[16:18:23] <Jymmm> ABSOLUTELY it can
[16:18:38] <pfred1> I didn't say it couldn't i just said I can't see it
[16:18:41] <Jymmm> you bevel the wire
[16:19:02] <maddogma> Having rouble going from 2.4.3 to 2.5. Getting Depends error on libtk-img, and pythong-xlib, etc
[16:19:09] <Jymmm> you'll need a rotary axis
[16:21:26] <pfred1> aptitude search libtk-img
[16:21:58] <pfred1> apt-cache depends libtk-img
[16:22:08] <pfred1> apt-cache policy libtk-img
[16:22:23] <pfred1> something there ought to tell you what is going on
[16:23:34] <pfred1> I just used debian's package manager to ditch all my nvidia stuff and switch over to ATI it's hawt package management
[16:24:22] * pfred1 misses his GTS 240
[16:25:17] <maddogma> apt-cache policy libt-img: Installed: None Candidate:None
[16:25:28] <pfred1> then install it
[16:25:36] <pfred1> aptitude install libtk-img
[16:25:39] <maddogma> Which respoitories do I need to have enabled?
[16:26:11] <pfred1> it sounds like a base package to me nothing too special
[16:26:33] <pfred1> I always enable contrib and non-free though
[16:26:50] <pfred1> why not?
[16:27:50] <pfred1> I need a new video card
[16:37:36] <maddogma> Thanks pfred1! It's installing now.
[16:40:15] <pfred1> maddogma that is good
[16:40:22] <pfred1> lets hope it works
[16:41:10] <pfred1> check out this rig!
http://www.youtube.com/watch?v=ddwrXA67bb4&feature=fvsr
[16:41:53] <pfred1> this guy is going to end up the first man on Mars
[16:42:40] <pfred1> ah, I put every flammible liquid I could find on this rig ....
[16:42:58] <pfred1> check out the lamp!
[16:54:49] <Loetmichel> pfred1: is that you?
[16:55:00] <pfred1> no
[16:55:09] <pfred1> I'm crazy but I'm not goofy
[16:55:17] <Loetmichel> hrhr
[16:55:30] <pfred1> that guy with the lamps was downright goofy
[16:56:00] <pfred1> you gotta respect a man that can modify a snowblower like he has though
[16:56:15] <pfred1> or maybe it was a tiller?
[17:26:15] <quqnuss> hello
[17:27:10] <pfred1> hi
[17:27:44] <quqnuss> i would like to as a question regarding registration in linuxcnc forum ..
[17:28:06] <quqnuss> whom sould i ask ?
[18:28:40] <skunkworks__> cradek: pfred1 : heh :)
[18:38:47] <WillenCMD> GO BLUES!! sorry not the right chat room for that but i couldn't help my self
[18:39:29] <WillenCMD> im just giong to re-name this channel #mywifeworksnightssoallidoisworkonlinuxcncandmachines
[18:39:39] <WillenCMD> a bit long but i could abbreviate it
[18:41:56] <Jymmm> WillenCMD: abbr to #geta[W|L]ife
[18:42:23] <WillenCMD> define life...
[18:42:43] <Jymmm> 42
[18:42:55] <WillenCMD> 42?
[18:43:34] <Jymmm> http://en.wikipedia.org/wiki/42_%28number%29
[18:44:24] <WillenCMD> lol
[18:44:37] <WillenCMD> great answer
[18:46:53] <WillenCMD> machining is my life, my grandfather did it, my dad does it, and now i do it.
[18:47:06] <WillenCMD> wouldn't do anything else
[18:52:44] <WillenCMD> actually if anyone ever needs something machined i'll do it... i have this mill in my basement and i can't seem to think of anything to make. i'll do it for free
[18:55:03] <pfred1> that is the biggest problem thinking of something to make
[18:57:04] <WillenCMD> i know... i spent so much time designing it and making it work now i have drawn a blank.. I made the neighbor kid two new brake lever's for his dyno... thats about it. I'll be down the the atc tool changer very soon just waiting on the 4 angular contact bearings
[18:57:16] <WillenCMD> done*
[18:59:22] <alex4nder> sick
[18:59:29] <alex4nder> my new concrete mill basin seems like a good choice
[18:59:41] <alex4nder> it just weighs 200 lbs, so moving it is a pain in the ass
[19:01:55] <WillenCMD> my mill and base weighs in at 736 lbs
[19:02:38] <pfred1> I have a dolly I can put my mill on
[19:02:44] * Jymmm ships the Cesium-137 to WillenCMD to machine
[19:02:52] <pfred1> each castor is rated for 600 pounds
[19:03:02] <pfred1> caster even
[19:03:54] <WillenCMD> why do i diserve that?
[19:04:08] <Jymmm> alex4nder: Nothing a few 1/4" steel rods wouldn't resolve
[19:06:57] <Jymmm> WillenCMD: I was jokingly "taking advantage" of your generious offer to mahine something for free is all. My apologizes if the humor/sarcasim came across wrong.
[19:07:31] <pfred1> like my old boss Petie used to say, "It'll never hurt ya!"
[19:07:32] <WillenCMD> no no not at all i joke with the best of them, its just hard to tell via text
[19:07:54] <WillenCMD> wanted to make sure i didn't say or do something thats all
[19:08:35] <Jymmm> WillenCMD: Yeah, I'm gonna send you a guberment controlled substance for you to fabricate without any protection in place while you start to glow in the dark form all the swarf produced and I just reap the benefits =)
[19:08:54] <pfred1> petie could have been defusing a nuclear warhead and he'd turn around and say his famous line
[19:09:09] <pfred1> it really didn't matter how hazardous the task
[19:09:27] <pfred1> It'll never hurt ya!
[19:09:28] <Jymmm> pfred1: And he diead at a ripe old age of 19 years
[19:09:41] <pfred1> Jymmm no he is a very rich old man
[19:09:46] <pfred1> makes about a million a day
[19:09:58] <Jymmm> pfred1: heh
[19:10:19] <pfred1> the demo business is pretty lucrative
[19:10:22] <Jymmm> what was the material wolverine was made from again?
[19:10:34] <Jymmm> pfred1: demolition?
[19:10:36] <WillenCMD> aniridium or something like that
[19:10:40] <pfred1> yes
[19:10:43] <Jymmm> WillenCMD: yeah, that's it.
[19:11:04] <Jymmm> pfred1: Cool, if he has any spare fuse laying aorund send me some
[19:11:06] <WillenCMD> <==Nerd
[19:11:25] <pfred1> I knew mazochhi too
[19:11:25] <Jymmm> pfred1: the yellow stuff =)
[19:11:31] <pfred1> or however his name is spelt
[19:11:42] <pfred1> you saw his equipment on the WTC site
[19:12:04] <pfred1> he was the lead demo on that job
[19:12:12] <Jymmm> cool,
[19:12:22] <pfred1> sammy was an asshole
[19:12:28] <Jymmm> I'd HOPE he make $1M+///day for risking lives
[19:12:28] <pfred1> but most in the demo racket are
[19:12:53] <pfred1> petie was OK though
[19:13:48] <pfred1> a buddy of mine lived in one of sammy's rentals and I've worked for him too
[19:31:02] <Jymmm> If I worked with explosives daily, I'd be an asshole too, not enough time for anyone's bullshit
[19:31:32] * Tecan is ircing with amber safty glasses
[19:31:35] <Tecan> cool effect
[19:32:06] <Jymmm> try irc via telnet and it'll be like you're on acid
[19:39:26] <Tecan> try it !~ ? ive been on acid for the last 8 years
[19:39:33] <Tecan> lol j/k
[19:42:05] <Tecan> ouch that coffee is hot
[19:43:04] <pfred1> I used to MUD in a telnet session
[19:45:49] <Jymmm> I'd love to toss up a telnet/ssh BBS, muds, doors, tradewars, etc
[19:46:12] <Jymmm> FidoNet!!!
[19:46:25] <pfred1> telnet how it scrolls makes it tough
[19:46:59] <Jymmm> really based on your terminal config though
[19:47:17] <pfred1> raw telnet is raw telnet
[19:47:27] <Jymmm> and funny thing is I used xmodem in january too
[19:47:47] <Jymmm> no, telnet still has some temrinal emulaton to it
[19:47:57] <pfred1> oh it is a terminal
[19:48:13] <pfred1> but if the server is scrolling then so are you
[19:48:56] <pfred1> which is why people write mud clients
[19:49:27] * pfred1 used to use tt++
[19:50:34] <djdelorie> just finished milling three more brackets:
http://www.delorie.com/photos/cnc/bldc-bracket-1.html
[19:50:57] <djdelorie> is cnc milling really this boring? Insert blank, press play, wait 25 minutes, remove part...
[19:51:14] <pfred1> only when you're good at it
[19:51:19] <djdelorie> ;-)
[19:51:25] <ReadError> hey djdelorie
[19:51:28] <djdelorie> hi
[19:51:31] <ReadError> where did you get your PCBs made?
[19:51:34] <pfred1> when it gets exciting it can get expensive too
[19:52:01] <djdelorie> dorkbotPDX -
http://dorkbotpdx.org/wiki/pcb_order
[19:52:24] <pfred1> it had to have taken them some time to come up with that name
[19:52:32] <djdelorie> but the prototype was at pcb-pool.com as part of a panel with some other boards, as they include a free solder paste stencil
[19:52:32] <ReadError> wow
[19:52:36] <ReadError> 1$ PSI
[19:52:52] <ReadError> they all purple?
[19:52:55] <djdelorie> read more carefully :-)
[19:53:27] <djdelorie> $5 PSI for three, $1 PSI if you're making a huge batch. Yes, they're all purple.
[19:53:59] <ReadError> they look nice
[19:54:07] <ReadError> how much did your 3pcbs run?
[19:54:20] <djdelorie> $75
[19:58:05] * djdelorie returns to the shop...
[20:01:13] <ve7it> Jymmm,

[20:14:21] <Tecan> no fn way a whole flat
[20:19:09] <r00t4rd3d> who uses threaded rod for lead screws?
[20:54:33] <Jymmm> http://www.youtube.com/watch?v=bgHpWVHXl4U
[20:54:58] <Jymmm> ve7it: Talented =)
[20:57:25] <Jymmm> ve7it: Extra creative

http://www.youtube.com/watch?v=UvenpZZc50Q&NR=1&feature=endscreen
[21:06:09] <joe9> djdelorie: do you have any pics on how you held the bracket down?
[21:32:33] <djdelorie> joe9: it was cut from a bigger piece, I drilled holes in each corner and used screws
[21:32:52] <joe9> ok, thanks.
[21:33:03] <djdelorie> heekscnc has an option to leave little tabs along the perimiter to keep the finished piece from flying away when it's cut out
[21:33:20] <joe9> djdelorie: another question, you spend a lot of time on the computer. Do you have wrist issues? rsi, and such?
[21:33:25] <djdelorie> nope
[21:33:48] <joe9> djdelorie: lucky you. any thing to do with your posture or keyboard?
[21:33:57] <djdelorie> football accident in high school
[21:34:03] <djdelorie> learned to type the "wrong" way
[21:34:12] <joe9> what is the wrong way?
[21:34:12] <djdelorie> also, I use a 1984 IBM Model M keyboard :-)
[21:34:20] <djdelorie> wrists *straight* not *parallel*
[21:34:49] <Thetawaves> i heard that rsi has nothing to do with typing
[21:34:51] <joe9> wrists "straight"? to what?
[21:34:59] <Thetawaves> its caused by too much *furious* masturbation
[21:35:00] <djdelorie> to your forearm
[21:35:15] <djdelorie> or golf ;-)
[21:35:53] <Thetawaves> :P
[21:36:07] <djdelorie> too much *furious* "golfing" ;-)
[21:36:13] <pfred1> I have a monster old IBM keyboard
[21:36:19] <joe9> djdelorie: i am not able to distinguish between "parallel" vs "straight" to the forearm. would you mind explaining it in a few more words, if you do not mind.
[21:36:30] <pfred1> thing is heavy like a hawaiian sufrboard
[21:36:40] <djdelorie> but really, I learned touch typing in high school while wearing a splint, learned to keep my wrists straight and my fingers more "hovering" over the keys rather than resting on the home row.
[21:36:51] <djdelorie> joe9: DON'T BEND YOUR WRISTS
[21:37:05] <djdelorie> that kind of straight
[21:37:06] <pfred1> know what makes my writs hurt?
[21:37:10] <djdelorie> lawyers?
[21:37:15] <pfred1> jackhammering
[21:37:19] <pfred1> man that messes me up
[21:38:17] <joe9> djdelorie: thanks for that good advice.
[21:38:42] <alex4nder> or you could do what I did when I had RSI,.. switch to a Kinesis Classic in Dvorak mode
[21:38:46] <alex4nder> keeps people off your workstation
[21:38:48] <joe9> djdelorie: i will stackup on keyboard pads.
[21:38:59] <joe9> i use dvorak.
[21:39:00] <djdelorie> wrist pads? I don't use them
[21:39:15] <joe9> tried datahand for a while, till it broke.
[21:39:56] <freespace> use a trackball might help too
[21:40:00] <freespace> *using
[21:40:32] <joe9> can i use dremel bits on my mill?
[21:40:42] <djdelorie> depends on what you're using them for
[21:40:55] <joe9> just some cutting and practicing.
[21:40:59] <pfred1> or how fast your mill goes
[21:41:13] <djdelorie> I'm using a CNC router bit that fits my dremel, although I'm not actually using the dremel itself...
[21:41:15] <joe9> it is a taig. about 10k rpm, i think
[21:41:23] <pfred1> top spindle speed on my mill is 2,500 RPM
[21:41:27] <pfred1> oh well then
[21:41:37] <pfred1> dremel bits it is!
