[00:04:11] <theorb> theorb is now known as theorbtwo
[00:32:34] <tom3p> where is Stuart's shop located?
[00:37:49] <tom3p> where is Stuart's shop located?
[01:41:58] <skunkworks> Wichita
[02:08:36] <Jymmm> skunkworks: You're not in Kansas anymore Dorthy
[04:29:00] <elmo40> Jymmm: find a way to drill an A size?
[04:29:53] <Jymmm> not yet
[05:31:15] <elmo40> http://www.cnccookbook.com/MTCNCPanels.htm
[05:33:36] <elmo40> anyone in Deutschland who require an MPG? ;) http://qurl.org/l41
[10:52:49] <AlbertNe> http://beagleboard.org/hardware ...check this out
[11:16:12] <mk0> will 10.04 install in this beagleboard?
[12:10:27] <AlbertNe> <mk0>...whats do u think?
[12:10:38] <AlbertNe> :)
[12:11:29] <mk0> i'm a little bit enchanted )
[12:11:52] <mk0> nice solution
[12:23:18] <AlbertNe> Since the BeagleBoard is open source, many projects using the Beagle Board are already in work
[12:50:42] <elmo40> but I thought it wasn't working on it yet. Or was that a different board.
[12:54:45] <alex_joni> there is no RTAI for beagleboard yet
[12:59:22] <AlbertNe> some one will manage it?
[13:00:01] <AlbertNe> can we downsize ubuntu as small as posible?
[13:02:09] <alex_joni> I doubt it makes sense to use ubuntu on the beagleboard
[13:02:12] <AlbertNe> http://gpspp.sakura.ne.jp/rtklib/rtklib_beagleboard.htm ..RealTime
[13:04:46] <Colinb> alex_joni you busy?
[13:08:29] <elmo40> anyone know of a linux backplot editor? something similar to this? http://www.cadkas.com/cnc-backplot-editor.php
[13:08:49] <elmo40> using vim and refreshing Axis is not all too convenient ;)
[13:09:24] <cradek> yes but it shows you results that exactly match emc, which is a very valuable feature
[13:10:10] <cradek> hey, they even know this: "Different CNC machines may interpret the same G-Code in a different way. The drawing of the tool path in our software therefore is no guarentee, that your CNC machine will interpret the G-Code in the same way as our software."
[13:10:54] <cradek> wow, they sure have a lot of icons
[13:12:39] <elmo40> it is for Windows. of course they have plenty of icons.
[13:12:47] <elmo40> all mouse based... drives me nuts ;)
[13:12:49] <cradek> I mean on that web page
[13:12:59] <Colinb> i use cimco edit for backploting
[13:13:08] <cradek> but yeah, mouse-based is tedious to use
[13:13:47] <elmo40> this is what gets me with heeks.
[13:14:11] <cradek> yeah, it needs some work to be keyboardable - it's pretty bad
[13:14:14] <elmo40> I have to click on the next variable I want to edit... Dan said it isn't his fault it is how the UI works, or something like that.
[13:14:35] <cradek> yep that's exactly what I had in mind - the list of parameters you have to fill out by clicking each one
[13:14:39] <Colinb> cimco was quite good in that it can also read hiedenhain code
[13:14:47] <Colinb> altho probably not relevant in here :)
[13:15:10] <elmo40> we use Cimco at work. Even have it installed on our machines for on-machine editing.
[13:15:49] <Colinb> yeah
[13:16:09] <Colinb> i only really use the backplots to quickly check the program is the one i want to run
[13:16:25] <Colinb> especially usefull when its a repeat order of a job from 6 months back
[13:17:19] <elmo40> this is the sort of thing I want to do from home: http://www.cam-expert.com/front-panel-gallery.html
[13:17:30] <elmo40> small simple things.
[13:20:23] <Colinb> its amazing how a simple annodies ally plate can make a $5 box of bits look like its worth $5000
[13:24:30] <JT-Work> anyone use anything like this to light up the keyboard? http://www.newegg.com/Product/Product.aspx?Item=N82E16800997047
[13:46:14] <elmo40> JT-Work: nah. well lit here.
[13:46:37] <JT-Work> I work in a cave with the lights out
[13:50:31] <elmo40> no worries about tornadoes, eh? ;)
[13:52:37] <JT-Work> no, it has been proven cat 5 tornado proof if it passes more than 900' away :/
[13:53:02] <JT-Work> but I don't want to test it again!
[13:55:17] <elmo40> then move the cave :/
[16:42:20] <skunkworks> http://groups.yahoo.com/group/mach1mach2cnc/message/122176
[16:42:55] <skunkworks> 'The "guts" of the software is now on it's own thread and allows a computer to swap screens without effecting the pulse output as much'
[16:43:00] <skunkworks> Good morning!
[16:43:10] <skunkworks> (we had an internet outage this morning)
[16:48:19] <JT-Work> without effecting the pulse output as much. Gotta love that
[16:49:51] <skunkworks> This is the broaching we did - pushed the gear on the left throuh the ring on the right. took about 12 ton.
[16:49:53] <skunkworks> http://electronicsam.com/images/KandT/conversion/yaxis/adapt-a-broach.JPG
[16:50:36] <JT-Work> you broached it in one pass?
[16:50:54] <skunkworks> that will be one end of the 'flex' coupling between the servo and the y axiis
[16:51:07] <JT-Work> cool
[16:52:21] <skunkworks> JT-Work: yes - but ran it though a few time to losen it up.
[16:52:47] <skunkworks> I think it was pretty close to the limit of our press.
[16:53:19] <JT-Work> must have been fun keeping it square while pressing it
[16:54:46] <skunkworks> not too hard. worked well.
[16:55:09] <skunkworks> we made a bit of a shoulder so it would start in the right location?
[16:55:15] <skunkworks> -?
[16:55:41] <JT-Work> heh
[16:56:41] <Jymmm> I dont get it
[16:56:43] <skunkworks> we just ground the back side of that gear so it was square.
[16:57:18] <Jymmm> no no no, the purpose
[16:57:24] <Jymmm> no no no, the whole purpose
[16:58:51] <Jymmm> the outside of the ring looks like it was meant to turn by hand
[16:59:24] <JT-Work> http://bridgeport.askmisterscience.com/bridgeport.htm
[16:59:51] <JT-Work> I don't feel so bad about taking two days to move my BP VMC off the trailer and in place :)
[16:59:54] <skunkworks> our y axis used to be driven with a hydraulic servo - gear driven - a small gear on the hydraulic servo drove the gear you see there (actually 2 gears stacked that could be pre-loaded for backlash). we don't have an easy way to get power into it - other than driving that gear. our first attemt was to rigidly attach a shaft to the gear - now we are going to couple to the gear.
[17:05:04] <Jymmm> JT-Work: I think the guy is nuts, apparently so did his sister!
[17:07:45] <Jymmm> skunkworks: So two gears will be fitting into that ring?
[17:10:31] <Jymmm> JT-Work: This is just so wrong... bolting to the edge of 2x8 joists?! I would have at least grabbed a 4x4 and shoved it in the corner of the room, then placed the pipe on top of it as a lever point
[17:12:31] <Jymmm> Hell, drill a 3" hole thru the joists, and put a length of pipe thru them or something.
[17:20:50] <Jymmm> JT-Work: Hey, here ya go.... http://bridgeport.askmisterscience.com/cart.jpg
[17:21:47] <Jymmm> JT-Work: add a hydraulic lift and you're all set
[17:21:58] <Jymmm> aka floor jack
[17:25:27] <elmo40> JT-Work: he could have removed the table to lighten it up a little more.
[17:26:08] <Jymmm> looks like he had a 2 ton hoist, so no bigy there
[17:27:36] <elmo40> 3-phase wiring? in the home? lol, read his caption http://bridgeport.askmisterscience.com/wiring.htm
[17:29:59] <Jymmm> He doens't give a good enough photo to see how he made the teepee
[17:30:25] <Jymmm> wb skunkworks
[17:31:36] <skunkworks> thanks
[17:31:56] <Jymmm> skunkworks: So two gears will be fitting into that ring?
[17:33:09] <skunkworks> no - the other gear (the one not in the picture but mounted on the machine) will be driven by that aluminum ring.
[17:33:27] <Jymmm> by belt?
[17:33:42] <skunkworks> no - that will be mounted to the end of a shaft.
[17:34:15] <Jymmm> so the ring is missing the mounting holes, yes?
[17:34:34] <skunkworks> yes
[17:34:43] <Jymmm> ok, NOW that makes sense =)
[17:34:52] <skunkworks> mounted to the end of this shaft instead of how it was going to be directly to the gear
[17:34:53] <skunkworks> http://electronicsam.com/images/KandT/conversion/yaxis/adapt1.JPG
[17:36:18] <Jymmm> The gear in the last pic is the same gear in the first pic?
[17:38:25] <skunkworks> no - it is the gear that is mounted in the machine
[17:39:06] <Jymmm> I'm confused, but that's okey =)
[17:39:17] <skunkworks> it is convoluted.
[17:39:34] <Jymmm> Yeah, just supply photos when finished =)
[17:39:40] <skunkworks> sure thing.
[17:40:36] <Jymmm> Because what I was thinking is why broach instead of just making a flat donut and bolting the two together
[17:41:36] <skunkworks> because it will allow for a little axial dissalignment. (is that a word?)
[17:41:47] <Jymmm> fudge factor
[17:41:51] <skunkworks> yes
[17:42:16] <AlbertNe> ..how can i install emc2 on Xubuntu?
[17:42:22] <Jymmm> But, if it took 12 Ton to broach them, how much fudge factor can it provide?!
[17:42:39] <skunkworks> it slides in and out by hand.
[17:42:44] <skunkworks> now.
[17:42:51] <Jymmm> OH! Ok, heh heh heh
[17:43:10] <Jymmm> skunkworks: very cool!!!
[17:43:24] <skunkworks> we ran it though a few times to losten it up. plus dad ran it in the lathe for a bit with a little axial dissalignment(sp) to losen it up more.
[17:43:28] <Jymmm> it all makes sense now.
[17:43:49] <skunkworks> loosen
[17:44:05] <Jymmm> * Jymmm speaks typo
[17:45:23] <Jymmm> Good variety of stations, and awesome playlists. http://181.fm/
[17:46:34] <AlbertNe> <skunkworks> i think its need linear scale encoder...
[17:46:44] <skunkworks> Jymmm: I like this station. http://minnesota.publicradio.org/radio/services/the_current/
[17:47:07] <skunkworks> AlbertNe: ?
[17:47:34] <Jymmm> skunkworks: Nah, where can you find Christmas variety in July =)
[17:47:49] <skunkworks> heh
[17:48:10] <Jymmm> skunkworks: They have like 3 or 4 Christmas stations
[17:56:46] <AlbertNe> <skunkworks> your new but old cnc.
[17:58:58] <skunkworks> AlbertNe: it has it's own version I would like to get working some day (accupins) but for now we are running it off encoders on the servos.
[18:00:07] <skunkworks> AlbertNe: http://electronicsam.com/images/KandT/conversion/accupinlineup.jpg
[18:00:49] <skunkworks> this is the positioning we get with just the encoders.... http://www.youtube.com/watch?v=FgOqEz5Tk-Y
[18:01:22] <skunkworks> :)\
[18:02:03] <skunkworks> this is x and z moving. http://www.youtube.com/watch?v=QU_O_Z7Vv8c&feature=channel
[18:02:16] <skunkworks> (working on Y atm)
[18:03:02] <elmo40> skunkworks: horrible tolerance :P +/- 0.00005 or so? :P
[18:03:09] <skunkworks> heh
[18:03:31] <skunkworks> I was going to be happy with +/- .001
[18:03:42] <skunkworks> well - maybe not. ;)
[18:04:37] <elmo40> mine is like that. maybe 0.0025 in the X and 0.002 in the Y. Home built machine with crappy ACME screws.
[18:04:51] <skunkworks> not bad.
[18:05:09] <elmo40> Z is an issue. it binds >_< need to straighten something and make the motor mount a little more rigid.
[18:05:22] <Jymmm> skunkworks: http://www.181.fm/player/
[18:07:55] <skunkworks> awesome 80!
[18:11:23] <Jymmm> skunkworks: The Mix
[18:12:06] <Jymmm> skunkworks: Actually, UK Top 40 isn't too bad either.
[18:13:12] <Jymmm> skunkworks: Damn... 18 Christmas stations
[18:13:44] <Jymmm> skunkworks: Even has Comedy Club =)
[18:47:29] <motioncontrol> good evening . have a problem ,but not understand it. i have start emc2.4.3 and lathe.ini configuration.start home is ok.select the program example :lathe-g76 , but when start have message : about line 26 Lenght of cutter compensation entry move is not greater then the tool radios. because it ?
[19:10:19] <mrsunshine> hmm, what is recomended to use for grinding tool steel ... i want to have a good flat surface afterwads for ball bearing balls =)
[19:10:35] <mrsunshine> so something that isnt expended in the grinding process :P
[19:44:22] <acciera> hi
[19:44:33] <mrsunshine> hmm, hows plastic as contact material for ball bearing balls? :)
[19:44:42] <mrsunshine> feels like it wouldnt be to good but ...
[19:44:51] <mrsunshine> plastic can be quite amazing at times :P
[19:49:06] <JT-Hardinge> what kind of plastic?
[19:49:41] <Jymmm> glass impregnated nylon is some tough stuff.
[19:50:04] <Jymmm> maybe not easy to machine, but great for mold injection.
[19:52:51] <mrsunshine> delrin or something
[19:53:52] <mrsunshine> im thinking of making my own linear guides =) will require two parts, one thats just a carrier and mounting part, the other a ball contact part
[19:53:58] <JT-Hardinge> delrin is fairly hard for a plastic
[19:55:26] <JT-Hardinge> Rulon makes a nice plain bearing material
[19:55:54] <mrsunshine> 25x8x1000mm flat bar of delrin for 162 sek .. (24 usd)
[19:56:21] <mrsunshine> not to expensive
[19:56:30] <mrsunshine> and a 1000mm bar would get me far realy :P
[19:56:56] <mrsunshine> tho gonna check with the local place that does cnc milling etc and see if i can get some scrap to test with first =)
[20:09:30] <JT-Hardinge> just drop by the house I have some left overs
[20:20:31] <mrsunshine> any 3d cad/cam system to recommend? :/
[20:21:14] <JT-Hardinge> SolidWorks
[20:21:26] <JT-Hardinge> 2010 Professional
[20:21:56] <acciera> inventor and inventorcam oder nx
[20:22:00] <acciera> or
[20:23:12] <alex_joni> mrsunshine: not enough information..
[20:24:04] <JT-Hardinge> hi alex_joni
[20:24:17] <alex_joni> hi JT-Hardinge
[20:51:04] <JT-Hardinge> It's always nice to solve a mystery
[20:52:10] <jthornton_> jthornton_ is now known as jthornton
[20:55:26] <JT-Hardinge> little coolant pump sure runs a lot quieter on 240v 1p instead of 480v 1p and cooler
[20:55:38] <JT-Hardinge> * JT-Hardinge wonders why the machine dealer connected the first 240v 1p pump240 to 480v 1p
[20:55:51] <JT-Hardinge> sure does explain a lot
[20:56:29] <skunkworks> heh
[20:57:03] <JT-Hardinge> kinda what I said but not quite
[20:59:36] <Jymmm> JT-Hardinge: I'll be right over, you'll have the smoker almost finished this batch?
[21:00:11] <JT-Hardinge> yep
[21:00:59] <Jymmm> hawt damn! What's on the menu for today? Pork? Beef? Bambi? Aardvark?
[21:01:23] <skunkworks> I have a crock pot slow cooking at home.
[21:01:37] <Jymmm> skunkworks: whatcha makin?
[21:02:25] <JT-Hardinge> opossum today Jymmm
[21:02:40] <Jymmm> JT-Hardinge: Isn't that grisseley?
[21:02:44] <Jymmm> (sp)
[21:03:08] <skunkworks> what was left over in the fridge.. Beef, carrots, potatos, beets,onions and celary - some paprica and carraway seeds. (s and p)
[21:03:37] <Jymmm> carraway seeds, hmmm. Might have to check that out.
[21:04:14] <skunkworks> that was just thrown together - we make a hungarian goulash(sp) that uses that and love it.
[21:04:22] <Jymmm> we use a lot of cummin and worchester sauce
[21:04:31] <Jymmm> ah, gotcha
[21:05:25] <skunkworks> I have been making a stirfry sause that is just corn starch, soy sause and garlic.
[21:05:43] <skunkworks> I think my spelling sucks today.
[21:05:48] <SWPLinux> normal
[21:05:49] <skunkworks> mor than normal
[21:05:50] <SWPLinux> ^W
[21:05:53] <skunkworks> hey!
[21:06:01] <SWPLinux> mor, eh?
[21:06:07] <SWPLinux> :)
[21:06:27] <skunkworks> ;)
[21:06:54] <SWPLinux> I was having all sorts of problems until I learned that NUM-LOCK is shared between the laptop and the USB keyboard, but caps-lock isn't
[21:07:08] <SWPLinux> (or at least the caps-lock lights don't both change, but num-lock lights do)
[21:07:10] <Jymmm> JT-Hardinge: Hey, you know the box I'm making. the front cover will have foam gasket material all around the edges. Now, the inserts for the chamber dividers... How much clearance would you guess that I should give them from hitting flush againest the inside face of the front cover? 1/4" then just use foam gasket on the divider edges?
[21:07:28] <SWPLinux> makes it awfully hard to type on the laptop when half the keyboard is a faux-numpad with num-lock on
[21:07:48] <Jymmm> heh
[21:08:18] <Jymmm> SWPLinux: You shuld consider the Apple full sized wired kybd, thin
[21:08:20] <JT-Hardinge> just depends on the foam gasket you use
[21:08:39] <SWPLinux> I have a cool Logitech illuminated one that's pretty thin too
[21:11:20] <SWPLinux> ah, here it more or less is: http://www.newegg.com/Product/Product.aspx?Item=N82E16823126043
[21:11:55] <SWPLinux> the only really annoying thing about it is that big delete key causing insert to be moved to where scroll-lock should be (and of course the missing scroll-lock key)
[21:12:39] <Jymmm> JT-Hardinge: http://www.homedepot.com/Tools-Hardware-Hardware-Fasteners-Weather-Stripping/h_d1/N-5yc1vZ1xglZard7/R-202066511/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
[21:13:06] <skunkworks> yeh - I have a bunch of issues going from my keyboard to others that don't have the same home to insert locations (those 6 keys)
[21:13:20] <SWPLinux> yeah
[21:13:46] <skunkworks> mine are 2 rows of 6 - and I am used to that.
[21:13:54] <skunkworks> vertical
[21:13:56] <SWPLinux> I like my Keytronic 3601PS2 (ish)
[21:14:11] <SWPLinux> 2 rows of 6?
[21:16:07] <skunkworks> http://www.newegg.com/Product/Product.aspx?Item=N82E16823109045&cm_re=microsoft_keyboard_wireless-_-23-109-045-_-Product
[21:16:16] <skunkworks> like that
[21:16:43] <skunkworks> uhh - 2 rows of 3
[21:16:47] <skunkworks> ;)
[21:16:54] <Jymmm> I love this keyboard... http://www.newegg.com/Product/Product.aspx?Item=N82E16823101006&cm_re=mb110ll%2fa-_-23-101-006-_-Product
[21:17:52] <Jymmm> The low profile keys is a bit deceptive. Going from my true lexark IBM kydb to this was great
[21:24:11] <acciera> andypugh got your mail twice^^
[21:24:24] <andypugh> gmail threw a fit
[21:24:35] <skunkworks> and that is how the qab interfaces with dap using the 6.64i protocal.
[21:24:42] <Jymmm> andypugh: you cant send ZIP files =)
[21:24:57] <andypugh> Huh?
[21:25:21] <Jymmm> andypugh: 2010-09-21 14:24:24 andypugh: gmail threw a fit
[21:25:39] <andypugh> Nothing to do with zip files.
[21:25:46] <Jymmm> then what?
[21:26:14] <andypugh> gmail got stuck, so I saved a draft, then pressed "send" again. It seems it sent both.
[21:26:31] <Jymmm> Ah, the JS. gotcha
[21:29:36] <Jymmm> JT-Hardinge: Ok, the foam is .1875 (not sure if that includes the adhesive or not). I guess I could double it up to 0.375 (2*.1875), leave .250 clearance when cutting the insert, then compressing the foam 0.125. Not should if that's even to give a air tight seal though.
[21:29:58] <Jymmm> s/should/sure/
[21:32:05] <Jymmm> As I am "borrowing" the use of someone's saw, I'm just not sure how much fudge factor to include.
[21:36:41] <Jymmm> Ah, ok. I got an idea - 1/4" it is =)
[21:50:22] <skunkworks> http://www.youtube.com/watch?v=_Ti7yJoLla4
[21:52:08] <alex_joni> nice
[21:52:56] <skunkworks> http://www.youtube.com/watch?v=RWkHclYqa6U
[21:53:45] <skunkworks> Hi alex
[21:53:52] <skunkworks> (waiting for my ride home)
[21:54:11] <alex_joni> take a bike ;)
[21:54:37] <JT-Hardinge> Jymmm: just get 3/8" thick foam
[21:54:38] <skunkworks> carpool. would like to in the future - need to be in a little better shape. getting there.
[21:55:30] <JT-Hardinge> I don't think that vid is running in real time lol
[21:57:29] <skunkworks> it isn't - he said actual running time was like 12min
[21:57:39] <skunkworks> bbl
[21:57:42] <JT-Hardinge> * JT-Hardinge wanders out to take the tiller off the tractor and put the box blade on... anyone want to help
[21:57:59] <JT-Hardinge> no speakers on the Hardinge yet :)
[22:00:02] <Jymmm> JT-Hardinge: This foam is closed cell, better quality than the others I've seen. Pleae I'll be getting a 30ft roll of it already. When I'll do is place a strip of it on the edge of the insert, and aother strip on the face of the front cover, then they can compress against each other =)
[22:00:50] <JT-Hardinge> JT-Hardingewanders out to take the tiller off the tractor and put the box blade on... anyone want to help
[22:01:21] <Jymmm> * Jymmm runs by home depot and sends couple workers over to JT-Hardinge's place
[22:02:00] <Jymmm> JT-Hardinge: is it that much of a pita?
[22:16:43] <JT-Hardinge> the tiller is a pita as it wants to roll over on you as you hitch and unhitch it the box blade is not bad
[22:18:20] <Jymmm> I'm surprised you haven't come up with some fixture to resolve that
[22:45:03] <JT-Hardinge> I only use it twice a year Jymmm
[22:45:12] <Jymmm> Ah
[22:45:20] <JT-Hardinge> you have to balance your ying and yang
[22:47:51] <JT-Hardinge> I'm actually making sausage surprise tonight for dinner, I couldn't find an opossum that was fresh enough
[22:48:16] <Jymmm> What, no raccoon or squirrel?
[22:48:28] <Jymmm> obnoxious neighbor?
[22:48:56] <JT-Hardinge> http://www.gnipsel.com/jtr/
[22:50:59] <Jymmm> that sounds good
[22:51:20] <JT-Hardinge> it is real good and easy to fix
[22:53:26] <JT-Hardinge> so you have your box all planned out now?
[23:08:47] <Jymmm> JT-Hardinge: Yeah, I'm not going to deal with dado'ing the chamber inserts right now, but I did account for them. I *JUST* finished the cut sheet. Glad I checked it as I found a booboo.
[23:21:27] <Jymmm> JT-Hardinge: You need to add a PORK and a ETHNIC category =)
[23:24:09] <tom3p> Fraunhoffer is selling a pick and place robot like the hexaglides Alex has shown, the specs are hard to believe ... Speed max 10 [m/sec] , Max. acceleration at 1kg 100 [m/secĀ²], Repeatable position accuracy +/- 0,1 [mm]
[23:24:11] <tom3p> http://www.elau.com/us/solutions/robotics/robot-p4.html
[23:50:20] <MattyMatt> do you think it uses the "integrated vision solution" for positioning?
[23:51:26] <MattyMatt> I was thinking about that earlier for a reprap on an arm. somebody is already making a delta prototype too
[23:52:11] <tom3p> i cant imagine that speed, so cant even speculate
[23:52:34] <tom3p> cool, i been using vismach to model a linkage, and found this http://www.qspider.org/ a src code-ubuntu-joint-simulator
[23:57:01] <MattyMatt> I did start learning russian in the 80s, when I was going to be a Rocket Scientist :) I can't say I ever got fluent
