[00:03:11] <les> yeah
[00:03:21] <les> why do you need such high res?
[00:03:33] <Jymmm> I have also found complete sets, but very small
[00:04:16] <Jymmm> what do yo mean "hi-res"? I typically work with 6MB 3000x2000x300dpi images
[00:04:38] <Jymmm> now, THAT's hi-res, but I dont need that good
[00:04:51] <les> well it's all relative... I like crisp graphics too
[00:04:55] <pfred1> Jymmm what? something too good for you?
[00:05:00] <les> haha
[00:05:05] <les> no!
[00:05:29] <Jymmm> heck, this is way too small --> http://www.amuseyourself.com/goodreads/leonardodavinci/leonardo-self-portrait.jpg
[00:05:35] <pfred1> and I thought nothing was ever good enough for Jymmm
[00:06:13] <pfred1> * pfred1 just got a hell of a deal at Big Lots
[00:07:00] <les> I won't argue...if the pixel count on the retinal plane is less than the cone cell count..I agree it's not good enough
[00:07:10] <pfred1> Leonardo Davinci wasn't he like a cross dresser and the Mona Lisa is a self portrait?
[00:07:24] <les> might have been
[00:07:34] <Jymmm> pfred1 Without DaVinci you wouldn't be here!
[00:07:43] <Jymmm> pfred1 he invented the screw
[00:07:46] <les> davinci and michelangelo were well...you know
[00:07:50] <pfred1> I don't think he's in my family tree
[00:07:59] <Jymmm> pfred1 here as #emc
[00:08:29] <pfred1> archemedes invented the screw
[00:08:29] <les> The screw? tell archimedes that
[00:08:35] <pfred1> jinx!
[00:08:51] <les> haha
[00:09:03] <pfred1> and that dope thought the screw was only good for moving water
[00:09:16] <les> uh yeah
[00:09:17] <pfred1> screw him!
[00:09:23] <les> haw
[00:09:30] <Jymmm> lol
[00:09:54] <pfred1> nah just because someone is credited for an idea first doesn't mean someone else already didn't do it or wouldn't have done it the next day
[00:10:30] <pfred1> the guy that put the lead screw on lathes is forgotten by history
[00:10:46] <pfred1> everyone figures he was to odamned busy working to be famous
[00:11:04] <pfred1> tho they believe he was French
[00:11:25] <pfred1> hi jerry
[00:11:25] <les> not forgotten by me...Maudslay
[00:11:32] <jerry> hey
[00:11:38] <les> hi jerry
[00:11:55] <jerry> little problem :)
[00:11:57] <pfred1> les well from what i hear the very first guy no one knows who they were I guess Maudslay is taking credit kinda like Marconi
[00:12:14] <les> heh
[00:12:19] <pfred1> or Edison for that matter
[00:12:33] <pfred1> who didn't invent half the things he claims to have
[00:12:42] <pfred1> he was the Bill Gates of his day
[00:12:52] <les> yup
[00:13:02] <pfred1> stealing everyone blind left right and center
[00:13:08] <les> right
[00:13:21] <pfred1> didn't get the better of George though now did he?
[00:13:34] <les> the phonograph is the real innovation I think of with edison
[00:13:50] <pfred1> yeah but again he had the completely wrong idea as to what it was good for
[00:13:54] <Jymmm> lightbulb?
[00:13:58] <pfred1> he thought it was going to be for dictation
[00:13:59] <les> yes true
[00:14:07] <pfred1> nah another frenchman invented the lightbulb
[00:14:19] <les> When I was in grade school I made one
[00:14:24] <jerry> got my homemade mill and emc running, but it's engraving backwards, i've edit ini and put a minus, swapped leads to steppers around, what else ?
[00:14:26] <pfred1> tho Edison did vacuum it
[00:14:50] <les> from threaded rod and an orange juice can and some wood and AL foil
[00:15:15] <les> it worked
[00:15:21] <les> I was pretty thrilled
[00:15:29] <pfred1> jerry maybe you should have olny reversed one thing?
[00:16:16] <pfred1> or are you hoping that three wrongs will make a right?
[00:16:18] <les> yeah if you reversed everything it would still be backwards
[00:16:41] <jerry> let me run out and swap one back
[00:17:00] <pfred1> yeah if it's odd an even fix won't do ya
[00:17:03] <Dmess> or be forward from the other end
[00:17:25] <pfred1> les man you should have seen me today fixing my Emglo
[00:17:36] <les> emglo?
[00:17:43] <pfred1> oh i had these big plans as to how I was going to do it until I actually started doing it
[00:17:52] <les> explain
[00:18:01] <pfred1> yeah Emglo is major manufacturer of gas air compressors
[00:18:05] <Dmess> whats an emglo??
[00:18:22] <pfred1> well they're big around here at anyrate
[00:18:25] <Dmess> what kind of gas??
[00:18:35] <pfred1> gasoline?
[00:18:51] <pfred1> you know pull the cord it goes put put
[00:19:06] <Dmess> oh i see....
[00:19:23] <Jymmm> * Jymmm knows push the button and it goes putt putt
[00:19:24] <Dmess> portable air compressor
[00:19:46] <Dmess> runs off a petrol engin
[00:20:42] <pfred1> yeah only portable because it has wheels on it
[00:20:50] <pfred1> thing must weigh about 300 pounds
[00:21:03] <Dmess> i know the sort
[00:21:16] <pfred1> and of course the hole in it was in the bottom of the tank :O
[00:21:32] <pfred1> so I figure hey easy I take the head and the motor off of it
[00:21:44] <pfred1> yeah good thing I didn't go with that plan!
[00:21:45] <Dmess> the wheels only make it look like a few good men could mov it
[00:22:11] <pfred1> they must bolt it together then weld the mounting plate to the tank after things bolted together
[00:22:14] <Dmess> oh no plan B first off... nexer good
[00:22:19] <jerry> no help to remove the minus from ini anything else ?
[00:22:25] <pfred1> because there's no way you're going to get the inside hardware back!
[00:22:49] <pfred1> so I had to flip this thing over fully assembled
[00:23:20] <Dmess> did you drain all the fliuds first
[00:23:32] <pfred1> took the gas tank off but I'd already changed the oil
[00:23:36] <pfred1> so ...
[00:23:47] <Dmess> plop..
[00:23:50] <pfred1> I had a coffee can catching what was coming out the breather tube
[00:24:05] <pfred1> I guess it's really cleaned out now!
[00:24:09] <Dmess> did you weld the tant??
[00:24:13] <pfred1> yeah
[00:24:16] <Dmess> tank..
[00:24:38] <pfred1> it just had this little pinhole in it but I wanted it to be a flat weld job didn't want to play with side or overhead
[00:24:50] <Dmess> ive got one set up but its too loud...
[00:24:54] <pfred1> tho in retrospect I probably could have side jobbed it
[00:25:01] <jerry> ping cradek
[00:25:25] <pfred1> jerry so how do you know your machine is running backwards?
[00:25:33] <Dmess> we weld blind lotsa times
[00:25:47] <pfred1> Dmess this is my compressor
[00:26:00] <pfred1> if it was someone else's I'd have winged it too
[00:26:31] <Dmess> we do it on our own and customers stuff
[00:26:35] <jerry> because the file i trying is a logo, harley-davidson, comes out, but you need a mirror to read :)
[00:27:12] <pfred1> jerry and you've run the file in a sim and it's right way around?
[00:27:12] <Dmess> hmm have you got an axis inverted some how??
[00:27:32] <paul_c> jerry: Change the sign of the *_SCALES on either X or Y
[00:27:37] <jerry> not in the sim, but qcad shows it in the correct fashion
[00:27:40] <paul_c> but not both.
[00:28:10] <jerry> paul_c: in the ini?
[00:28:14] <Dmess> sign of scale sounds like the most likely culprit
[00:28:35] <pfred1> paul_c if it's coming out a perfect mirror how is one axis going right and one wrong?
[00:28:52] <pfred1> and why is z right?
[00:29:48] <Dmess> is ther a mirror image parameter in EMC as on some CNC machines
[00:30:02] <paul_c> nope.
[00:30:23] <pfred1> Dmess it could be handy
[00:30:39] <pfred1> I bet jerry wishes there was one right about now
[00:30:58] <Dmess> is this file a piont to point program or does it hac g02 g03 in it??
[00:31:04] <cradek> jerry: pong
[00:31:17] <jerry> where is the *SCALES, idon't recall that from ini
[00:31:34] <pfred1> jerry grep -in scales *ini
[00:31:35] <paul_c> [AXIS_0]
[00:31:56] <paul_c> INPUT_SCALES = 1000 0
[00:32:04] <jerry> hey cradek how bout a short how to on you image to gcode ?
[00:32:05] <paul_c> OUTPUT_SCALE = 1000 0
[00:32:32] <jerry> paul_c: yea, just tried to change that from no sign to a minus, no change
[00:32:42] <paul_c> (line 156 & 157)
[00:33:15] <jerry> change x and y to minus still assbackwards
[00:33:28] <pfred1> in vi can't you find stuff by just goinng /term ?
[00:33:34] <paul_c> There - You did both x & y
[00:33:43] <jerry> ah, just one
[00:33:47] <paul_c> ;)
[00:33:54] <pfred1> that's what paul_c has been saying
[00:34:00] <jerry> ok, i'll be back
[00:34:08] <pfred1> tho it isn't the intuituive fix
[00:34:16] <paul_c> * paul_c hands pfred1 a copy of emacs
[00:34:32] <pfred1> you'd think if they both going wrong you'd have to change both
[00:34:40] <pfred1> paul_c thanks but I prefer xemacs
[00:34:55] <pfred1> RMS can go hang!
[00:35:15] <paul_c> * paul_c sneaks a copy of word in...
[00:35:38] <pfred1> sorry I don't do Windows
[00:35:48] <Dmess> im new to EMC but an old cnc hack with 15 yrs and too many controls to remember
[00:36:13] <cradek> jerry: did you compile it?
[00:36:21] <Jymmm> * Jymmm installs EDLIN on pfred1's computer!
[00:36:21] <cradek> jerry: did you compile it successfully?
[00:36:29] <pfred1> yeah i should be down in my mad scientist's lab working tonite but it's wet down there
[00:36:34] <Dmess> any one here ever sen the TOSNUC 888 cnc controller
[00:36:45] <pfred1> Jymmm I got a system with edlin on it
[00:37:04] <Jymmm> pfred1: XP comes with EDLIN btw
[00:37:08] <pfred1> has like dos 3.3 on it or something
[00:37:35] <pfred1> and Donkey Kong!
[00:37:43] <Dmess> cool...
[00:38:57] <pfred1> yeah too bad last time i fired that system up I had to spin the HDD spindle with a pencil eraser to overcome it's sticktion
[00:39:21] <pfred1> and that must have been about 10 years ago now
[00:39:31] <pfred1> someday I'll make a neat electroplater out of it
[00:39:42] <pfred1> the 5V bus in it is not to be believed!
[00:39:55] <Dmess> i had one here the dh was so loud the wife and kids would leave the family room if ifire it up
[00:40:46] <pfred1> ah as I can remember it's quiet like the dead are
[00:40:56] <Dmess> but it ran a 5 axis APT system so we had to have it to make G-codes
[00:46:30] <cradek> * cradek shrugs
[00:48:02] <jerry> still bassackwards, after changing x axis to minus, changed back to no minus, changed y axis to minus
[00:48:26] <SWPadnos> are you changing the right ini file?
[00:48:56] <pfred1> yeah when you change things and nothing happens you have to wonder
[00:48:59] <jerry> let me double check that
[00:49:30] <paul_c> [hint] generic.run -ini foo.ini
[00:58:24] <Jymmm> Anyone read Italian?
[00:59:06] <A-L-P-H-A> I look at hot Italian women from time to time? does that count?
[00:59:18] <SWPadnos> yeah - like who ;)
[00:59:40] <Jymmm> some how I doubt that; unless you know one of these italian chics that can read italian
[00:59:41] <A-L-P-H-A> SWPadnos, hot girls that are in Little Italy. :)
[00:59:46] <SWPadnos> heh
[00:59:57] <A-L-P-H-A> you been in there?
[01:00:02] <SWPadnos> I have a sister that lived in Florence for 5 years - she may be able to help
[01:00:05] <A-L-P-H-A> OMG... summer time is the place to be.
[01:00:16] <pfred1> A-L-P-H-A you like them with mustaches?
[01:00:30] <A-L-P-H-A> pfred1, they're Canadianized Italian WOPs.
[01:02:59] <SWPadnos> Jymmm: are you looking for Da Vinci's low cost CNC router plans? :)
[01:03:18] <A-L-P-H-A> ohoh? free plans? I'll take a copy.
[01:03:26] <SWPadnos> low cost
[01:04:00] <A-L-P-H-A> I want free.
[01:04:38] <SWPadnos> Then consult Van Gogh's plans
[01:04:45] <SWPadnos> though the accuracy isn't so great
[01:05:54] <A-L-P-H-A> SWPadnos, are you just making people now? Next you'll tell me there's a set from Raph, and Donatello.
[01:06:09] <SWPadnos> And Mike - can't forget Mike
[01:06:26] <A-L-P-H-A> What about Leonardo...
[01:06:31] <A-L-P-H-A> TMNT!
[01:06:47] <SWPadnos> We already went over Leonardo's plans - they're not free :)
[01:07:03] <A-L-P-H-A> oh yeah.'
[01:07:06] <jerry> time to try another day, need to find my copy of the ini files, now i'm getting following errors
[01:07:09] <A-L-P-H-A> short attention span.
[01:07:10] <SWPadnos> I'll tell you - you really didn't want to work in a movie theater when TMNT or TMNT2 came out
[01:07:34] <A-L-P-H-A> what? you didn't like all the little boys that didn't shower, watching TMNT?
[01:07:52] <A-L-P-H-A> must have been a nice smell in the theatre.
[01:07:54] <A-L-P-H-A> hahaha
[01:08:13] <SWPadnos> I didn't like the parents who didn't care to actually throw out their leftover buckets of popcorn and soda
[01:08:24] <SWPadnos> like "tip it over on the floor - it's OK"
[01:08:43] <A-L-P-H-A> so it's people doing it on purpose!
[01:08:47] <jerry> cradek: back to your proggy
[01:08:53] <A-L-P-H-A> stick floors is so gross to me.
[01:08:55] <SWPadnos> yes it is
[01:09:04] <SWPadnos> yeah - and there's no time to mop between shows
[01:09:11] <SWPadnos> there's barely time to push a broom through the theater
[01:09:20] <A-L-P-H-A> nastiness.
[01:09:31] <A-L-P-H-A> I never worked in the service industry.
[01:09:57] <A-L-P-H-A> just lifeguarding ( beach and then pool ), and then as a programmer.
[01:10:10] <A-L-P-H-A> now a consultant, with a expensive hobby.
[01:10:11] <A-L-P-H-A> damn CNC.
[01:10:22] <SWPadnos> It's good to try those shoes for a little while - makes you a better person
[01:10:48] <A-L-P-H-A> SWPadnos, <shrug> I'm me...
[01:10:56] <cradek> jerry: so what do you want to know?
[01:10:57] <SWPadnos> well - you're not good enough :)
[01:11:05] <SWPadnos> or - you could be even better :)
[01:12:35] <A-L-P-H-A> :)
[01:13:41] <jerry> hey, are still there
[01:13:55] <SWPadnos> are?
[01:14:02] <jerry> cradek:
[01:14:06] <cradek> ??
[01:14:15] <jerry> your still here...
[01:14:24] <SWPadnos> jerry: did you get the mirror image problem fixed?
[01:14:32] <jerry> question about your image to gcode
[01:14:43] <SWPadnos> nevermind - I missed one line of yours
[01:14:56] <jerry> SWPadnos: no, gave up for today, following errors now
[01:15:06] <jerry> so i need to find my copy of the ini
[01:15:14] <SWPadnos> right - INPUT and OUTPUT scales need to be the same sign
[01:16:00] <jerry> ok, i'll make em the same when i fire it up in the morning
[01:16:04] <SWPadnos> cool
[01:16:29] <jerry> cradek: how about a short howto run your program
[01:16:46] <cradek> here goes:
[01:16:53] <cradek> read the file named README
[01:17:01] <pfred1> woo tonite is Mythbusters nite!
[01:17:42] <jerry> didn't get a readme, otherwise i would have read the readme
[01:17:44] <cradek> (that's it, in case you're still waiting)
[01:17:59] <cradek> you didn't??
[01:18:19] <cradek> doh!
[01:18:21] <jerry> where's it supposed to be ?
[01:18:32] <cradek> sorry, I wasn't reading what you were writing
[01:18:41] <cradek> I thought you were talking about the TrueType tracer
[01:18:51] <jerry> no, image to gcode
[01:19:03] <cradek> I see that, my mistake
[01:19:26] <cradek> well, edit image-to-gcode.py to point to your image (the input image is hardcoded!)
[01:19:41] <cradek> then just run it with python like:
[01:19:45] <cradek> python image-to-gcode.py
[01:20:13] <cradek> you can tweak step and depth to get the output you want
[01:20:18] <pfred1> cradek can't get it to read the commandline?
[01:20:30] <cradek> pfred1: patches accepted
[01:20:58] <cradek> pfred1: see the front page of my website under "Welcome" (http://timeguy.com)
[01:21:32] <pfred1> cradek well it's just such a common thing that evne shell scripts seem to manage to do
[01:21:41] <pfred1> yeah maybe wrap it in a shell script?
[01:21:54] <jerry> cradek: thanks, i'll gaive it a shot
[01:22:08] <cradek> I'm not saying it's hard, it's just that I didn't do it that way, and I don't care to fix it
[01:22:24] <cradek> my new philosophy is to share what I do, no matter how finished it is
[01:22:28] <cradek> (how finished it's not!)
[01:22:48] <pfred1> ah take some pride :)
[01:22:50] <pfred1> heh
[01:22:57] <pfred1> j/k
[01:23:00] <cradek> really, read my front page
[01:23:06] <pfred1> we want kari!
[01:23:21] <cradek> if I worried about everything being perfect, I'd never share anything, because it never is.
[01:23:22] <pfred1> I'm too busy staring at kari
[01:24:04] <pfred1> cradek so you're disorganized are you?
[01:24:09] <cradek> so I'm giving everyone 80% of a finished image-to-gcode convertor, that actually already works.
[01:24:36] <cradek> there's value to that, and if I wanted to polish it up first, it would have to wait for "someday"
[01:24:40] <pfred1> hey 80% is pretty good
[01:24:57] <pfred1> someday I hope to be 80% organized
[01:25:00] <cradek> heh
[01:25:33] <cradek> so people have to edit the file, or fix it themselves - if they can't handle that you don't have any business running a cnc machine anyway, so I don't care
[01:25:44] <cradek> err "they"
[01:25:57] <pfred1> cradek man it's got to be as easy as pressing the print button
[01:26:07] <cradek> I doubt I'm 80% organized, but I do finish most things 80%
[01:26:26] <pfred1> well in demo we always say it's finished at 90%
[01:26:44] <pfred1> because if we tried for 100% well sometimes 101% is bad!
[01:27:00] <pfred1> whoops you mean we weren't supposed to take that down?
[01:27:47] <pfred1> an 8 inch fire main can really let loose some water
[01:27:55] <pfred1> you'd be suprised!
[05:03:32] <A-L-P-H-A> are we having fun yet?
[08:11:36] <anonimasu> * anonimasu yawns
[08:11:39] <anonimasu> morning alex
[08:26:02] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[08:33:27] <alex_joni> morning
[08:33:30] <alex_joni> I gotta run
[08:33:30] <alex_joni> bye
[08:36:35] <A-L-P-H-A> SWPadnos, you up?
[09:39:37] <anonimasu> hm
[09:39:38] <asdfqwega> * asdfqwega proceeds with trepidation - hacking autotrace to output splines in .dxf
[09:40:56] <asdfqwega> Problem - scanning something to a raster image. Converting with autotrace to .dxf, it makes the splines into plines
[09:41:06] <asdfqwega> plines with up to 10k segments!
[09:41:44] <asdfqwega> Then, when I want to scale the .dxf to something I can use, I end up with LOTS of little lines
[09:42:08] <asdfqwega> Qcad 2.0.4 can read splines, so off I go
[09:43:36] <asdfqwega> I love it - I am re-learning C, figuring out the .dxf format, and reading somebody else's code, simultan-
[09:43:39] <asdfqwega> simul-
[09:43:42] <asdfqwega> simul-
[09:43:49] <asdfqwega> ...at the same time.
[09:46:03] <anonimasu> asdfqwega: check: www.wotsit.org
[09:46:56] <anonimasu> simultaneously
[09:47:03] <anonimasu> ;p
[09:47:42] <anonimasu> * anonimasu runs around in circles screaming
[09:53:41] <A-L-P-H-A> asdfqwega, I don't know of a program that can machine splines yet... so why not leave them as little lines?
[10:00:49] <anonimasu> hm, emc someday :)
[10:00:58] <asdfqwega> Mostly is a matter of processing the file prior to outputting g-codes
[10:01:04] <anonimasu> some machines do splines
[10:01:11] <anonimasu> splines/nurbs
[10:01:36] <asdfqwega> To keep a good approximation of the picture I'm scanning, I gotta keep the resolution up
[10:02:03] <asdfqwega> However, autotrace outputs stuff in integer coords, where 1 pixel = 1 unit
[10:02:52] <asdfqwega> So, typically, I have to scale things by 1/1000 in Qcad to get them into my work envelope
[10:03:46] <asdfqwega> The problem is that autotrace has already converted to high-resolution polyline
[10:04:47] <A-L-P-H-A> probably a setting in autotrace to do what you want.
[10:05:14] <asdfqwega> Scaled down, convert to g-code = multi-megabyte g-code file full of tiny, tiny moves
[10:05:36] <A-L-P-H-A> asdfqwega, that' slog down turbocnc, I know that.
[10:05:51] <A-L-P-H-A> wonder how emc would handle it?
[10:06:16] <asdfqwega> with emc, sometimes it works, sometimes not
[10:06:37] <asdfqwega> I think with not, it exceeds the max number of lines
[10:06:59] <A-L-P-H-A> is http://www.textdrive.com, or http://status.textdrive.com working for anyone?
[10:07:45] <asdfqwega> Plus, there's a certain amount of tweaking I have to do to the .dxf before I can use it - and I can't edit the polylines in Qcad
[10:08:24] <A-L-P-H-A> asdfqwega, you can convert the spline to a pline. you know that right? And then you can run an optimizer on the pline (lisp or vb)
[10:08:31] <A-L-P-H-A> this is in autocad at least.
[10:09:18] <asdfqwega> * asdfqwega smacks A-L-P-H-A around with an Windows and AutoCAD EULA
[10:09:28] <A-L-P-H-A> :(
[10:09:30] <asdfqwega> I am not using Autocad!
[10:09:38] <A-L-P-H-A> that's bitch abuse... I'm calling the cops
[10:10:50] <asdfqwega> I have a bitch? That's news to me...
[10:11:01] <asdfqwega> I've been known to bitch...
[10:12:12] <asdfqwega> Qcad (Camexpert) actually converts the splines for gcode output
[10:12:37] <asdfqwega> but it's a lot more reasonable size
[10:23:07] <asdfqwega> textdrive works for me
[10:29:49] <A-L-P-H-A> asdfqwega, works now.
[10:29:56] <A-L-P-H-A> but not all the servers being hosted there.
[10:30:02] <A-L-P-H-A> I'm going back to sleep
[10:32:00] <anonimasu> * anonimasu is listening to bach
[10:40:03] <anonimasu> I am having trouble..
[11:38:27] <asdfqwega> I need some geek advice: How do you grep through a directory of files for something?
[11:38:33] <alex_joni> greetings.. again
[11:38:48] <alex_joni> grep -R -e REGEXP *
[11:38:56] <alex_joni> don't recall if it's R or r
[11:39:17] <asdfqwega> Oh, so I don't need to redirect it, cool
[11:39:28] <asdfqwega> thanks
[11:42:44] <alex_joni> yw
[11:42:54] <alex_joni> asdfqwega: where are you located?
[11:43:42] <asdfqwega> Middle of Bumfsck, Egypt :(
[11:43:50] <asdfqwega> Ohio, USA
[11:43:55] <alex_joni> heh
[11:44:00] <alex_joni> can you try an address for me?
[11:44:06] <asdfqwega> Za?
[11:44:14] <alex_joni> www.robcon.ro
[11:44:20] <alex_joni> damn site seems to be down again
[11:44:25] <alex_joni> it's in TX
[11:44:50] <asdfqwega> Eh? What's it doing?! No! NOOOOOOOOOOOOO~
[11:44:52] <asdfqwega> NO CARRIER
[11:45:04] <alex_joni> lol
[11:46:23] <asdfqwega> "Unknown host"
[11:48:31] <alex_joni> thx
[11:56:33] <alex_joni> morning paul_c *g*
[12:01:02] <paul_c> Afternoon Alex.
[12:04:50] <alex_joni> what's up?
[12:05:56] <anonimasu> * anonimasu hits the PLC
[12:06:25] <anonimasu> did you know that every problem you solve creates 3 others?
[12:07:47] <asdfqwega> I've heard variations on that, yeah
[12:08:57] <anonimasu> it's true..
[12:10:30] <anonimasu> I should take a break before I break somthing more.
[13:11:46] <Dmess> anyone here interested in some cnc manuals??
[13:12:06] <alex_joni> Dmess: what kind?
[13:12:14] <Dmess> what you need??
[13:12:22] <paul_c> What you got ??
[13:12:41] <Dmess> some of this and some of them...
[13:12:51] <paul_c> okaaayy...
[13:13:03] <Dmess> fanuc tosnuc siemens heidenhain
[13:13:26] <paul_c> next Q.... Will you be anywhere near Washongton DC at the end of April ?
[13:13:30] <Dmess> ibeen every where man
[13:13:44] <Dmess> im in toronto canada
[13:13:54] <paul_c> Not that far north..
[13:14:11] <Dmess> oh we still need the dog team...
[13:14:24] <Dmess> at least till the ice breaks up
[13:14:33] <paul_c> spring has sprung over here..
[13:14:48] <Dmess> then we can break out the kayaks
[13:15:08] <Dmess> here to the penguins are matin'
[13:15:21] <Dmess> that how we can tell
[13:16:59] <Dmess> but seriously what manuals do you need im going to ask my isp to let me post a few isos
[13:17:52] <Dmess> the TOSNUC 888 has to be scanned and fudged yet
[13:18:00] <paul_c> You looking at scanning them and putting them up as pdf files ?
[13:18:13] <Dmess> hoping to
[13:18:26] <Dmess> you have an easy way to do that
[13:18:27] <paul_c> (copyright infringements..)
[13:19:17] <Dmess> not postin... just for friendly instructional / development principles same way i use them
[13:20:02] <paul_c> Already have a couple of the TNC manuals, but others would be usefull for comparision.
[13:20:19] <alex_joni> * alex_joni agrees
[13:20:23] <Dmess> ive worked on about 300 different cnc machine and control combinations in the last 18 yrs
[13:20:43] <Dmess> have tnc 530i cd
[13:22:05] <paul_c> You don't have any plans for attending the codeFest do you ?
[13:23:22] <Dmess> Unfortunately NO Im hoping to be into a new workplace and possibly flying in our nat's out west so wife says 1 trip limit
[13:24:39] <paul_c> tell her you're going to the pub ?
[13:25:50] <Dmess> what pub??
[13:27:01] <paul_c> idunno... There must be several in the Gaithersburg area <grin>
[13:27:22] <Dmess> oh... nahh she's seen me go for coffe and come back 3 days later without the truck...LOL
[13:28:10] <alex_joni> nice ;)
[13:28:24] <Dmess> but we found out that a suburban is much more aerodynamic when its upside down
[13:29:04] <Dmess> but you really gotta get into the air brakes to roll her back onto the wheels again
[13:29:40] <paul_c> back to the manuals...
[13:29:47] <Dmess> certainly
[13:30:02] <Dmess> what controls have you run over
[13:30:30] <paul_c> Heidenhain, ANC,....
[13:31:00] <Dmess> ANC??
[13:31:17] <alex_joni> I played with a Burny
[13:31:33] <Dmess> what the oldest??
[13:31:43] <paul_c> Adolf Numerical Controls - Boxford used them on their lathes.
[13:32:36] <Dmess> P & W Star-Turn Tape-O-Matic 1967 the yr i was born
[13:33:55] <Dmess> GE 550,1050 , fanuc 2 & 3 & 5 & 9
[13:37:18] <Dmess> heidenhain & siemens have most all their manuals posted on the web
[13:37:46] <Dmess> too heavy for us little service guys to carry them all
[13:39:03] <paul_c> damit... ANC appear to have disappeared from the www
[13:40:58] <Dmess> ive never run over one ..odd
[13:41:09] <Dmess> watch within a week... ; )
[13:41:18] <paul_c> do you have a URL for the Siemens manuals ?
[13:42:29] <Dmess> try this www3.ad.siemens.de/doconweb/
[13:42:33] <alex_joni> * alex_joni is back after a while
[13:44:08] <Dmess> you wanna be flabergasted get into an 840D with foll contouring 5 axis
[13:44:34] <Dmess> yup link still works
[13:45:17] <Dmess> chk out the DMG Evolution Series of machine
[13:47:15] <paul_c> bookmarked - The pdf links aren't playing ball with my usual browser...
[13:48:04] <Dmess> ive got the doc on cd as well
[13:50:48] <Dmess> which siemens do you have access to
[13:53:57] <paul_c> don't have access to any Siemens systems..
[13:54:15] <Dmess> have you looked at the live BDI - morphix based installation
[13:54:27] <paul_c> a little...
[13:54:50] <Dmess> im having a hard time getting it to stick on one machine
[13:55:18] <paul_c> Give the BDI-4.xx a go.
[13:55:28] <paul_c> (4.20 is the latest)
[13:55:35] <Dmess> allways wants me to do an e2fsck and i did
[13:56:21] <paul_c> Are you shutting down correctly before hitting the power Off ?
[13:56:40] <Dmess> SI
[13:56:47] <Dmess> yes
[13:58:35] <Dmess> then its as if it duffed the FS.. becz it wont go back on at all even from the cd...
[13:59:07] <Dmess> i throw 2.08 on.. then morphix live works again
[13:59:20] <Dmess> 2.1.8 sorry
[13:59:59] <Dmess> im seeing a 4.18 no 4.20
[14:00:40] <paul_c> Check the HDD BIOS settings - Set it to LBA mode for large disks...
[14:01:13] <Dmess> yes..
[14:01:35] <Dmess> fdisk wont let me clean it up
[14:02:24] <Dmess> it sees an invisable logical drive in the ext dos partition so cant delete it
[14:04:05] <paul_c> Not seen that before....
[14:05:50] <Dmess> but the 2.1.8 goe asks if i want to remove data ..Yes.. go gone reboot system without a network or an ftp command...
[14:06:10] <Dmess> band in the live cd... get it all..
[14:07:24] <Dmess> its probably just something im yuckin up
[14:07:33] <paul_c> the BDI-2.xx series are obsolete and are unlikely to receive any updates...
[14:07:58] <paul_c> BDI-Live has been superceeded by BDI-4.xx
[14:08:14] <Dmess> fine... hey any way to transfer scrips from one bdi version to another
[14:08:40] <paul_c> gcode files ?
[14:09:07] <Dmess> no under scripts... like loop
[14:09:47] <Dmess> or the confersational programming module from 2.8.1
[14:10:02] <Dmess> coversational
[14:10:17] <paul_c> cp1 is included in BDI-4
[14:10:45] <Dmess> offset setting??
[14:10:50] <Dmess> teach
[14:11:42] <paul_c> tool offsets & work offsets are supported.
[14:11:43] <Dmess> i have a full set of probing macros for the tosnuc 888 that might be useful to implement
[14:12:10] <Dmess> all the tough stuff is done just have to re-assigh the variables
[14:12:46] <Dmess> but what about teaching the work offset... you are here...CLICL
[14:13:18] <paul_c> right click on one of the axis readouts.
[14:13:36] <Dmess> ok i see
[14:14:05] <Dmess> im a moron .. did i mention that.. to obvious for me
[14:14:54] <Dmess> 2.1.8 has a cute little scrip window with a teach button .. looks very pro
[14:15:41] <Dmess> any support for user defined g or m codes??
[14:16:01] <paul_c> M codes, yes.
[14:16:23] <Dmess> how many
[14:16:37] <paul_c> M100 to M199
[14:16:58] <Dmess> ok so probing with single m codes is doable
[14:17:31] <paul_c> 'pends what you are expecting a custom M code to do...
[14:18:05] <paul_c> M codes (in general) should not be commanding moves.
[14:18:20] <Dmess> call a parametric subroutine and pass thru some vars
[14:18:49] <Dmess> then gimme some custom G codes
[14:19:24] <Dmess> or developmental g codes possibly for later addition to the source
[14:19:39] <paul_c> You have the source code ?
[14:20:03] <Dmess> i have all the source parametric routines yes
[14:20:30] <paul_c> and the source code for EMC
[14:21:07] <Dmess> yes but adding to that at this point is above and beynd my capabilities
[14:21:50] <alex_joni> * alex_joni is back
[14:21:59] <alex_joni> paul_c: that's a nice one .. I'll remember that
[14:22:04] <Dmess> these could be called as subroutines ... or am i incorect gosub...return
[14:22:10] <alex_joni> [17:02] <Dmess> have you looked at the live BDI - morphix based installation
[14:22:10] <alex_joni> [17:02] * acemi has joined #emc
[14:22:10] <alex_joni> [17:02] <paul_c> a little...
[14:22:24] <alex_joni> Dmess: paul_c did the BDI's ;)
[14:22:37] <paul_c> alex_joni: YOU spoiled it...
[14:22:46] <alex_joni> * alex_joni hides
[14:22:57] <Dmess> well good.. then i got the right guy.. ; )
[14:23:01] <paul_c> * paul_c has the GPS coords...
[14:23:03] <alex_joni> right.. you didn't want Dmess to know that
[14:23:06] <alex_joni> :D
[14:23:10] <paul_c> and a LCCM
[14:23:17] <alex_joni> Dmess: if it won't work... blame paul_c
[14:23:29] <Dmess> dont worry be happy.. its all my fault... i know it
[14:24:10] <Dmess> hey i love the system and hope to run a little catia thru it soon..
[14:24:59] <paul_c> one thing that BDI-4 has....
[14:25:09] <paul_c> is samba client support.
[14:25:22] <Dmess> xplain pls?.
[14:25:34] <alex_joni> heh
[14:25:48] <alex_joni> Dmess: samba is a unix tool for Windows network support
[14:25:59] <alex_joni> supports Domains, workgroups etc
[14:26:01] <Dmess> hmmm nice idea..
[14:26:54] <Dmess> is there a buffered look ahead on the EMC

[14:29:27] <alex_joni> LOLOLOLOL
[14:29:47] <Dmess> what do yur trolls eat anyway???
[14:30:35] <paul_c> anything they can get their teeth in to.
[14:31:17] <Dmess> odd... ours seem to go for the women and children first
[14:31:54] <Dmess> must be all that soap they use
[14:35:14] <alex_joni> you think?
[14:35:23] <Dmess> 4.18 has Synergy included or support??? CNC too??
[14:35:38] <alex_joni> Dmess : Synergy as eval-version
[14:35:42] <alex_joni> 30 day trial
[14:36:23] <Dmess> nice.. anyone remember HELIX... cadcam??
[14:37:04] <Dmess> apparently available as open source now but no longer supported
[14:37:28] <Dmess> might make one heck of a system
[14:40:37] <paul_c> Don't confuse open source with GPL, or any of the other FOSS licences...
[14:42:23] <alex_joni> HELIX? doesn't ring a bell
[14:43:04] <Dmess> well it seemed i read they were making it available for recompilation ..but dont call us
[14:43:30] <Dmess> big in mould making .. nice core cavity routines
[14:46:26] <paul_c> right... I'm off to burn a fag or two, and grab a bun.
[14:46:44] <Dmess> nice to have met you paul
[14:46:53] <paul_c> I'll be back.
[14:47:14] <SWPadnos> remember - don't burn the bun and grab the fags :)
[14:47:17] <alex_joni> sounds like a particular calif. guvernor...
[14:47:26] <Dmess> doo
[14:47:29] <alex_joni> hey Stephen
[14:47:30] <SWPadnos> The GOVERNATOR
[14:47:34] <SWPadnos> Hi Alex
[14:47:36] <alex_joni> right
[14:49:53] <alex_joni> how's it going SWP?
[14:49:59] <SWPadnos> OK
[14:50:24] <SWPadnos> A little bit of a late night last night (and I still haven't finished that PC board)
[14:51:00] <alex_joni> bugger that ;)
[14:51:17] <SWPadnos> yeah - at least I know all the parts are in stock at DigiKey
[14:51:37] <SWPadnos> PC mount screw terminals are large
[15:03:58] <Dmess> gotta fly later and thx all...
[15:04:00] <alex_joni> really ?
[15:04:04] <alex_joni> SWP: really?
[15:04:04] <alex_joni> :D
[15:05:51] <SWPadnos> yes
[15:06:30] <SWPadnos> I can't find any screw terminals less than 5mm pitch, unless I use connectors (which aren't wanted on this board)
[15:06:53] <stevestallings> 3.5 mm are commonly available
[15:07:01] <SWPadnos> It shouldn't be a problem, but when there are 58 terminals on a board, it gets a bit big
[15:07:25] <SWPadnos> I've seen 3.5 or 3.81mm headers, but not screw terminals (at least, not in the DigiKey bible :) )
[15:11:33] <stevestallings> Not sure we are talking same terms, header vs. screw terminal blocks. I was thinking of Digikey part # ED1514
[15:12:50] <SWPadnos> right - I had seen those
[15:14:03] <SWPadnos> I forgot to mention that I'm doing this board as a volunteer (so I don't want to define new components), and I acctually may need higher than 6A ampacity :)
[15:14:33] <SWPadnos> (but that is the type of part I'm referring to)
[15:15:25] <stevestallings> k 8-)

[15:36:31] <Dmess> N980M2
[15:36:33] <Dmess> opps sorry didnt mean to grab that much
[15:36:39] <alex_joni> heh
[15:37:01] <Dmess> is that a good heh
[15:37:09] <SWPadnos> what is FOMT[]?
[15:37:20] <alex_joni> that's misspelled for FONT
[15:37:36] <SWPadnos> could be
[15:37:44] <Dmess> where?
[15:37:47] <SWPadnos> (but why have a font of sin(x)?
[15:37:56] <alex_joni> that's Wingdings
[15:38:04] <SWPadnos> after the IF lines - [VY=VJ+VX*FOMT[SIN[VB]*10000]/10000]
[15:38:16] <Dmess> nope ist TOSNUC for function
[15:38:44] <SWPadnos> OK. What is TOSNUC? :)
[15:38:51] <Dmess> toshiba control
[15:38:57] <SWPadnos> ok
[15:39:10] <Dmess> similar but stronger than fanuc
[15:39:24] <SWPadnos> so this does a circular probe?
[15:40:11] <Dmess> i believ tis probes a post... i dont remember off hand but i have a BUNCH of routines
[15:40:24] <Dmess> auto tool length and the likes
[15:40:46] <alex_joni> coo
[15:41:06] <SWPadnos> auto tool length can be pretty easy, actually
[15:41:17] <SWPadnos> at least in terms of the hardware needed
[15:41:54] <Dmess> yes...
[15:42:17] <alex_joni> * alex_joni goes away
[15:42:21] <Dmess> i have laser set ups as well
[15:42:22] <SWPadnos> see ya
[15:42:22] <alex_joni> bye guys
[15:42:31] <Dmess> bon jour
[15:42:32] <alex_joni> SWP: I have a full mirror now on my site
[15:42:36] <alex_joni> on all the BDI's
[15:42:40] <SWPadnos> cool
[15:42:52] <SWPadnos> all the previous revs as well?
[15:42:53] <alex_joni> http://dsplabs.utt.ro/~juve/emc/
[15:43:16] <SWPadnos> cool
[15:43:46] <Dmess> boookmarked.. ; )
[15:46:05] <SWPadnos> I've got a closer mirror, but I haven't made it fully public yet (worried about bandwidth :) )
[15:47:30] <alex_joni> Dmess: should have plenty bandwidth here
[15:47:39] <alex_joni> take all you need
[15:47:56] <alex_joni> bye
[18:20:12] <Dmess> anyone used coil activation sequences... personally??
[18:20:31] <SWPadnos> nope
[18:28:12] <anonimasu> hm..
[18:59:32] <anonimasu> hm
[18:59:47] <anonimasu> does anyone have a hinch on speed/feed for alu=?
[19:00:13] <paul_c> yup
[19:00:19] <anonimasu> care to share?
[19:00:20] <anonimasu> :p
[19:00:27] <paul_c> once I find the chart...
[19:00:31] <anonimasu> ok
[19:00:36] <anonimasu> I'll be milling alu for the first time..
[19:00:45] <anonimasu> since I got my z working
[19:01:57] <paul_c> 12mm cutter run at ~1500rpm
[19:02:22] <anonimasu> hm, I'll be using a 8mm cutter
[19:02:36] <anonimasu> 3flute 6mm cutter
[19:02:53] <anonimasu> more likely.. I dont know if I have collets for a 2 flute 8mm one
[19:03:27] <paul_c> 3000rpm
[19:04:00] <anonimasu> ok, that's the most my mill will do.. somwehere around it..
[19:04:14] <anonimasu> what feed?
[19:04:19] <paul_c> and you want a feedrate of approx 0.025mm per tooth per rpm
[19:04:28] <anonimasu> hm, how do you calc that?
[19:04:47] <paul_c> 225mm/min
[19:04:51] <anonimasu> ah nice..
[19:05:02] <paul_c> 0.025 3 3000
[19:05:13] <paul_c> 0.025 x 3 x 3000
[19:05:48] <anonimasu> hm much Z can I take per pass?
[19:05:53] <anonimasu> how much..
[19:05:53] <anonimasu> err
[19:09:03] <paul_c> for slot drills, half the cutter Dia
[19:09:13] <anonimasu> ok
[19:09:19] <anonimasu> for a 3flute endmill?
[19:09:27] <anonimasu> 25% maybe?
[19:09:33] <paul_c> slot cutting ?
[19:09:41] <anonimasu> hm.. contouring
[19:09:46] <anonimasu> or pocketing..
[19:10:20] <paul_c> OK... Work on 30-50% step over...
[19:10:23] <anonimasu> ok
[19:10:37] <paul_c> and depth of cut = Dia
[19:11:35] <paul_c> If this is a HSS cutter, reduce that by 15-25%
[19:12:16] <anonimasu> it is a hss cutter
[19:12:56] <paul_c> OK... For a 6mm Dia cutter....
[19:13:24] <paul_c> step over of 2mm, and DOC of 4mm
[19:13:44] <anonimasu> ok
[19:13:50] <anonimasu> I am without cooling btw..
[19:13:55] <paul_c> Climb mill and flood coolant to clear the chips.
[19:14:29] <paul_c> or an air line to blow the chips out.
[19:14:32] <anonimasu> yeah
[19:14:35] <anonimasu> I'll do that..
[19:15:13] <paul_c> with this CNC lark, you really do need a coolant supply...
[19:15:50] <anonimasu> yeah
[19:16:01] <anonimasu> I cant run flood coolant without a enclosure..
[19:16:16] <anonimasu> and I need better motor mounts and shielding to keep stuff out of my servos..
[19:17:11] <paul_c> without coolant, I'd recommend reducing the feedrate
[19:17:28] <anonimasu> 100mm/min?
[19:17:45] <paul_c> 150mm/min
[19:17:48] <anonimasu> ok
[19:18:33] <paul_c> with ali, you will get a buildup on the cutting edges without some lubrication...
[19:18:48] <paul_c> Got a can of WD40 ?
[19:18:54] <anonimasu> yeah
[19:19:09] <paul_c> a few squirts will help.
[19:19:34] <anonimasu> will lighter cuts help?
[19:19:55] <anonimasu> hm, vital + the new spindle motor will help ;)
[19:19:57] <paul_c> lighter cuts won't stop the buildup
[19:20:11] <anonimasu> hm..
[19:20:58] <Imperator_> Hi all
[19:21:32] <Imperator_> anonimasu: if you have a real machine make big chips instead of making dust out of the alu
[19:22:00] <Imperator_> that means 0.1 or 0.2mm per tooth
[19:22:22] <Imperator_> with a 6-10mm tool
[19:22:50] <anonimasu> hm, how real is real?
[19:23:08] <anonimasu> real like the mill I found on a sale?
[19:23:13] <anonimasu> :p
[19:23:33] <anonimasu> takes over 1 ton on the table
[19:24:00] <anonimasu> although I cant fit it anywhere..
[19:27:44] <anonimasu> bleh.. the hole I am about to make will take 73 minutes.
[19:28:12] <paul_c> bigger cutter ?
[19:28:45] <anonimasu> it's a 52mm hole...
[19:29:10] <paul_c> 2" slot drill would do that...
[19:29:13] <anonimasu> lol
[19:29:23] <anonimasu> I might aswell turn on the machine and then leave the reast to god and go and take a bath..
[19:29:30] <anonimasu> :p
[19:29:37] <anonimasu> god/whatever evil that controls what happens
[19:30:03] <anonimasu> I dont think I need to pocket it..
[19:30:10] <anonimasu> I could just mill out the center part of it..
[19:31:30] <anonimasu> or order a boring head..
[19:31:34] <anonimasu> :)
[19:31:37] <anonimasu> and drill the hole
[19:35:40] <anonimasu> hm, well I'll contour it out and then just facemill the whole part.. until it falls out..
[19:37:06] <anonimasu> that'll be faster..
[19:37:28] <anonimasu> hm, if I want to keep more feed what's the requirement other then flood coolant?
[19:38:04] <Imperator_> 1 tonne, souds like a real one
[19:39:20] <anonimasu> yeah, but I couldnt fit it anywhere..
[19:39:26] <Imperator_> had a discusion with one who sells tools, a month ago
[19:39:28] <anonimasu> so I had to pass :)
[19:39:41] <Imperator_> ?
[19:40:28] <Imperator_> and what kind of mill do you have now ?
[19:40:46] <anonimasu> a benchtop one..
[19:41:01] <Imperator_> whats that ?
[19:41:08] <anonimasu> dunno..
[19:41:11] <anonimasu> 1.7kw
[19:41:21] <Imperator_> hmm
[19:41:27] <Imperator_> not so much
[19:41:42] <anonimasu> or well that's what it says..
[19:41:51] <anonimasu> but I overdrive it from the vfd..
[19:41:58] <anonimasu> got a 4kw one on a shelve at work.
[19:42:38] <Imperator_> that man says don't cut to slow in aluminium, if you can. Than you will have less problems with getting the chips away and with the cutting edges of the tool
[19:43:11] <Imperator_> use a tool with max. two teeth
[19:43:27] <anonimasu> hm, "slow"
[19:43:31] <anonimasu> define that :
[19:43:32] <anonimasu> :)
[19:43:39] <anonimasu> < 1000mm/min?
[19:43:50] <Imperator_> 0.1-0.2 mm per teeth
[19:44:10] <Imperator_> or 0.3 :-)
[19:44:16] <anonimasu> lol
[19:44:23] <Imperator_> with a 10mm tool
[19:44:33] <anonimasu> I increased my feed a bit..
[19:45:14] <anonimasu> cant sit and idle for 70 minutes..
[19:45:22] <anonimasu> 17 is much better.
[19:46:22] <Imperator_> what type of tools do you have ?
[19:46:45] <anonimasu> dormer 6mm 3flute hss cutters..
[19:47:02] <anonimasu> I have some 8mm slotdrills aswell but I am unsure if I have collets that'll take them..
[19:47:16] <Imperator_> HSS, ohh
[19:47:37] <Imperator_> hardmetall is cheap today
[19:47:50] <Imperator_> or how is it called in english ?
[19:47:51] <anonimasu> yeah the carbide ones was double the cost..
[19:48:17] <anonimasu> 86$
[19:48:18] <anonimasu> ;)
[19:48:43] <Imperator_> hm, 10mm end mill hardmetall about 12 EUR here
[19:48:55] <Imperator_> the cheap ones
[19:49:03] <Imperator_> good enough for alu
[19:49:06] <anonimasu> dormer isnt cheap :)
[19:49:08] <anonimasu> but they are godo
[19:49:09] <anonimasu> good
[19:49:18] <Imperator_> ok for steel we take also the 80 EUR ones
[19:49:36] <Imperator_> our baby at work: http://www.digma.de/pages/dmasch_500.html
[19:49:38] <anonimasu> the hss ones are about 35eur
[19:49:48] <anonimasu> damn you :)
[19:49:54] <Imperator_> for HSS ?
[19:50:00] <Imperator_> :-)
[19:50:01] <anonimasu> yeah
[19:50:36] <Imperator_> 16kW Spindel up to 40000rpm up to 20000mm/min speed
[19:51:09] <anonimasu> nice toy :p
[19:51:10] <Imperator_> that machine compined with TEBIS is realy nice
[19:51:12] <Imperator_> www.tebis.de
[19:52:01] <anonimasu> nice
[19:52:11] <Imperator_> that machine is my example for building my one one
[19:52:55] <paul_c> * paul_c wants the HSC800
[19:52:56] <anonimasu> I am looking at the demo when they mill a sculpture with it
[19:53:07] <anonimasu> yeah..
[19:53:16] <anonimasu> I wonder what $ one like that would be
[19:53:24] <Imperator_> also with a polymer concrete frame but i have only some 1kW spindels from precise (60000rpm)
[19:53:25] <anonimasu> too much.
[19:53:46] <Imperator_> HSC800 too big
[19:53:51] <anonimasu> no way.
[19:53:54] <anonimasu> heh
[19:53:58] <Imperator_> HSC500 compact nice machine
[19:54:00] <Imperator_> :-)
[19:54:24] <anonimasu> I'd seriously re-build my shop if I had enough money for a machine like that..
[19:54:26] <Imperator_> 150 000EUR
[19:54:31] <anonimasu> hm, affordable..
[19:54:51] <anonimasu> but way out of my league
[19:55:23] <SWPadnos> stick with the small high speed ones :)
[19:55:36] <anonimasu> lol
[19:55:38] <Imperator_> spindels ?
[19:55:40] <anonimasu> I doubt they are cheaper..
[19:55:54] <SWPadnos> starting at $4800
[19:55:57] <SWPadnos> starting at $48000
[19:56:09] <anonimasu> lol.. a new car is about 12000
[19:56:11] <anonimasu> :p
[19:56:15] <anonimasu> or rather a newer one
[19:56:53] <SWPadnos> Imperator_: these - http://www.datrondynamics.com/products.htm
[19:56:59] <anonimasu> yep..
[19:57:06] <anonimasu> I think les router works at about that speed..
[19:57:07] <anonimasu> :)
[19:57:15] <Imperator_> have sean them on the EUROMOLD
[19:57:20] <SWPadnos> wait - only $46,800 to start
[19:57:23] <anonimasu> Imperator_: any good?
[19:57:24] <Imperator_> seen
[19:58:14] <Imperator_> hmm i was surprised that you can do so much with such a windy gantry machine
[19:58:46] <Imperator_> the moving portal is out of steel, filled with polymer concrete
[19:58:54] <Imperator_> 4kW spindel
[19:59:00] <Imperator_> HF-Spindel
[19:59:29] <Imperator_> ok if you compare it with a Digma machine it is a toy
[19:59:39] <Imperator_> but not bad
[19:59:41] <anonimasu> never heard about digma..
[19:59:49] <SWPadnos> a small fast toy though :)
[20:00:04] <Imperator_> small company with very good machines
[20:00:14] <Imperator_> Digma
[20:00:19] <anonimasu> ah thoose..
[20:00:28] <anonimasu> bleh..
[20:00:33] <anonimasu> who needs a good car anyway.
[20:01:01] <anonimasu> I am looking at that tebis video
[20:01:13] <anonimasu> where they mill a sculpture
[20:01:39] <Imperator_> the Digma can do the same parts that can the Datron do in Alu but in hardened steel :-)
[20:02:04] <Imperator_> we can mill steel up to 63HRC
[20:02:29] <Imperator_> hm don't know ecactly but it depends only on the tools
[20:03:29] <anonimasu> brb.. moving out to the shop
[20:04:04] <Imperator_> have also to put some videos online from our Digma
[20:04:40] <Imperator_> have some nice videos
[20:23:01] <anonimasu> :)
[20:23:09] <anonimasu> Imperator_: I am looking forward to seeing them
[20:23:50] <Imperator_> ask me next week
[20:27:22] <anonimasu> ok
[20:32:55] <anonimasu> hm time to run this..
[20:37:41] <anonimasu> fsck.
[20:37:50] <anonimasu> I broke a endmill.
[20:44:04] <Imperator_> HSS ?
[20:44:13] <Imperator_> hope the spndel is still ok
[20:44:18] <Imperator_> spindel
[20:44:42] <anonimasu> probably..
[20:45:04] <anonimasu> * anonimasu is annoyed
[20:45:45] <anonimasu> crap mill.
[20:46:08] <Imperator_> :-)
[20:46:11] <anonimasu> what happened was that I ran out of spindle power...
[20:46:17] <paul_c> * paul_c spent �32 on a 3mm long series ball nose cutter....
[20:46:31] <paul_c> Broke it in less than 2 mins of use.
[20:46:33] <anonimasu> and the table just snapped the endmill off..
[20:46:49] <anonimasu> I need to reduce my gearing or get a larger motor..
[20:47:14] <anonimasu> * anonimasu is tired of fscking around
[20:47:33] <anonimasu> always messing, with every little thing.. the only thing it's good at is milling foam..
[20:47:43] <anonimasu> or alu at 50mm/min..
[20:47:57] <anonimasu> but 50mm min means that every single part will take more then 5 hours to complete..
[20:48:28] <Imperator_> hm
[20:53:16] <anonimasu> well, I better try again..
[20:54:38] <anonimasu> with smaller stepdown...
[20:56:21] <anonimasu> if I decrease the stepdown and increase the feed..
[20:56:26] <anonimasu> might that help..
[20:57:10] <anonimasu> hm 50 minutes.. of machining..
[21:01:07] <anonimasu> went up to 66
[21:01:27] <Dmess> flood the table add isopropyl alcohol to the the mix
[21:02:49] <anonimasu> Dmess: that wont help..
[21:03:09] <anonimasu> Dmess: I have too little spindle power to make the chips..
[21:04:43] <anonimasu> :/
[21:04:46] <Dmess> what rpm and pwr have you got
[21:05:21] <anonimasu> 3000
[21:05:30] <anonimasu> 2700 1.7kw
[21:05:41] <anonimasu> or 2500 on the marking
[21:06:16] <robin_sz> lets see now ..
[21:06:17] <paul_c> Should be plenty for a 6mm cutter
[21:06:22] <robin_sz> oh I know ...
[21:06:27] <robin_sz> MEEP!!
[21:06:40] <Dmess> should make chips... to get HSM you could add a spinner
[21:08:11] <paul_c> (DOC x WOC x F x 1.34)/4 = KW @ Spindle (for ali)
[21:08:16] <Dmess> but 6mm at 3000 rpm should cut hrc 45 without too much trouble
[21:08:39] <Dmess> yeah that ...
[21:09:55] <SWPadnos> is F in mm/sec for that equation?
[21:10:39] <anonimasu> hm..
[21:10:48] <anonimasu> Dmess: spinner?
[21:11:28] <paul_c> SWPadnos: Units in inches...
[21:11:46] <SWPadnos> OK - I was thinking the KW requirements were a bit high :)
[21:12:13] <paul_c> getting 188 watts for a 1/4 cut
[21:12:16] <Dmess> multiplyer... 1 rev in 6.2 out
[21:12:32] <Dmess> or whatever
[21:12:42] <SWPadnos> though that's only about 3 CI/min per KW - is that right?
[21:13:04] <SWPadnos> (CI = in^3)
[21:14:13] <anonimasu> hm, but I run the spindle at the max gearing..
[21:14:18] <anonimasu> I cant remember what ratio it is..
[21:14:50] <anonimasu> well time for another try..
[21:15:05] <les> hi guys
[21:16:03] <paul_c> Evening Les.
[21:17:09] <les> sucking some digital photos in here
[21:17:30] <les> happened to get a good shot of congo and his pet chicken
[21:17:54] <les> he fell asleep on the porch and the chicken snuggled right up next to him
[21:17:56] <les> funny

[21:25:46] <CIA-9> 03petev * 10emc2/src/hal/drivers/hal_motenc.c: Initial revision.
[21:30:07] <anonimasu> I halved the feed
[21:30:16] <anonimasu> cuts better now
[21:31:27] <anonimasu> although I am making dust..
[21:31:41] <les> uh oh chip load low...
[21:32:02] <anonimasu> yeah
[21:32:16] <les> consider halfing the depth of cut instead
[21:32:25] <les> if you are power limited
[21:32:55] <les> course it will work with powder chips
[21:33:13] <les> just the tool dulls more rapidly
[21:33:54] <anonimasu> I decresed the speed..
[21:33:57] <anonimasu> to match better.
[21:34:02] <les> where did robin vanish off to?
[21:34:25] <SWPadnos> He's helping Batman
[21:34:34] <les> ah of course
[21:35:11] <les> or running to Geneva about that stamp licking job or whatever he's pondering
[21:37:06] <CIA-9> 03petev * 10emc2/src/hal/drivers/Makefile: Added files for MOTENC-100 board.
[21:38:47] <CIA-9> 03petev * 10emc2/configs/core_servo.hal: Initial revision.
[21:41:25] <anonimasu> bleh..
[21:41:37] <anonimasu> very high feed and lighter cuts..
[21:41:53] <anonimasu> to keep the chipload reasonable..
[21:42:36] <les> I had to do a lot of that with the turkey call production code
[21:42:52] <les> That's why I am getting a bigger spindle
[21:43:58] <les> pretty much time=k/kW
[21:48:46] <anonimasu> * anonimasu sighs
[21:48:47] <anonimasu> yeah
[21:48:53] <anonimasu> I got a 4kw one laying around at work..
[21:49:19] <anonimasu> the spindle rpm drops too much and the part gets scrapped..
[21:49:36] <anonimasu> because I lack the torque to maintain cutting at the higher chipload..
[21:49:53] <anonimasu> I decreased the speed to get a better chipload.. but a tiny bit too much and the spindle stalled..
[21:50:33] <anonimasu> I should get that vital and take 0.4mm cuts and feed at 1500mm/min
[21:50:40] <anonimasu> or more.
[21:51:07] <SWPadnos> if you slow down the feed too much, the cutting load increases
[21:51:23] <anonimasu> hm, I increased it.. actually..
[21:51:26] <anonimasu> and decreased the speed..
[21:51:28] <anonimasu> :)
[21:51:41] <SWPadnos> you need to maintain the proper feed, and then set depth based on spindle HP
[21:51:53] <anonimasu> hm..
[21:51:55] <anonimasu> I need a new mill.
[21:52:17] <SWPadnos> heh - if you really have a 1.7KW head, that's higher power than my Bridgeport
[21:52:27] <anonimasu> SWPadnos: heh
[21:52:37] <anonimasu> well I have it geared to get the max speed up..
[21:52:53] <anonimasu> so it's not 1.7kw at the spindle..
[21:53:00] <SWPadnos> and I'm able to cut aluminum with a 1.5" diameter, 6-flute end mill
[21:53:12] <anonimasu> hm, the 4kw will be nice.
[21:53:15] <SWPadnos> at around 10 IPM :)
[21:53:27] <SWPadnos> I could go faster, but I can't crank too fast :)
[21:53:35] <SWPadnos> (or consistently)
[21:53:46] <anonimasu> how deep cuts do you take with that?
[21:54:04] <SWPadnos> 1/4" or so, a little less if I'm being careful
[21:54:20] <anonimasu> hm..
[21:54:28] <anonimasu> I wonder why my mill does this..
[21:54:29] <SWPadnos> actually, more like 0.15 - 0.2 inches
[21:54:40] <anonimasu> I was taking a 2mm cut..
[21:54:53] <SWPadnos> you have to calculate feeds and speeds in order
[21:55:18] <SWPadnos> actually, spindle RPM, feed rate, then depth of cut
[21:55:40] <SWPadnos> (shall I go on, or am I telling you what you already know? :) )
[21:55:44] <anonimasu> lol
[21:55:51] <anonimasu> nothing of that is a probelm..
[21:56:02] <anonimasu> I know you should keep yourself to cutting data..
[21:56:16] <Dmess> broke a few end mills myself...
[21:56:22] <anonimasu> but without torque you cant cut anything..
[21:56:38] <SWPadnos> 1.7kw is plenty of spindle power
[21:56:43] <SWPadnos> 2.25 HP
[21:57:01] <anonimasu> yeah but it's geared at max also..
[21:57:10] <SWPadnos> same amount of power
[21:57:28] <anonimasu> oh, but that gives a higher speed..
[21:57:37] <anonimasu> and less torque..
[21:57:54] <SWPadnos> but you don't need as much torque with a smaller diameter cutter
[21:58:00] <anonimasu> the motor is rated at 2800rpm at 60hz..
[21:58:05] <SWPadnos> (which is why you have the higer speed)
[21:58:08] <anonimasu> I might be running it too fast.
[21:58:19] <pfred1> anonimasu never too fast!
[21:58:21] <anonimasu> I run 50hz@200% from the vfd..
[21:58:26] <SWPadnos> too slow if anything (assuming 50 Hz)
[21:58:34] <SWPadnos> right
[21:58:55] <pfred1> loud fast rules!
[21:59:08] <SWPadnos> what was your cutter diameter again?
[21:59:12] <anonimasu> 6mm
[21:59:17] <anonimasu> 2800*2
[21:59:24] <anonimasu> heh
[21:59:24] <gezr> was it high speed steel?
[21:59:26] <anonimasu> that might be a bit fast.
[21:59:27] <gezr> and hello yall
[21:59:27] <anonimasu> yeah
[21:59:31] <pfred1> it's not the size of your tool but the skill with which you drill
[21:59:57] <gezr> (80/.340)*3.82=rpm or abouts
[22:00:07] <gezr> Im not sure what 6mm in inch is
[22:00:19] <anonimasu> " = 254mm
[22:00:41] <anonimasu> err 25.4
[22:00:47] <SWPadnos> like Paul said, you want around 3000 RPM
[22:00:59] <pfred1> Pontiac zoom!
[22:01:03] <SWPadnos> and 2800 is fine, if a tiny bit slow
[22:01:12] <gezr> 80surface feet per minute if its steel your cutting
[22:01:22] <SWPadnos> (maybe run it at 50Hz * 130%)
[22:01:30] <SWPadnos> aluminum, so 200 or so
[22:01:46] <anonimasu> yeah somthing like it..
[22:01:50] <anonimasu> if so I am running way too fast..
[22:01:55] <gezr> or 400 sfm or just below the melting point, it depends on your cooling
[22:01:55] <SWPadnos> yes
[22:02:03] <SWPadnos> hand cooling :)
[22:02:08] <anonimasu> I could gear less.. and still keep the same speed..
[22:02:15] <gezr> to machine aluminum you need high pressure cooling to keep the aluminum from melting
[22:02:17] <anonimasu> and more torque to keep the spindle from stalling..
[22:02:44] <pfred1> speed thrills
[22:02:50] <SWPadnos> actually, you're probably having problems with the alu gumming up the mill
[22:02:57] <anonimasu> SWPadnos: no..
[22:03:07] <anonimasu> SWPadnos: the last endmill that broke was clean..
[22:03:09] <pfred1> yeah use comprssed air
[22:03:13] <SWPadnos> hmmm
[22:03:20] <anonimasu> the spindle stalled..
[22:03:25] <anonimasu> and broke in 3 pices inside of the collet..
[22:03:29] <SWPadnos> BTW - do you have any Tap Magic for Aluminum?
[22:03:30] <anonimasu> no
[22:03:37] <pfred1> then use compressed air
[22:03:41] <SWPadnos> bummer - it even smells nice
[22:03:42] <anonimasu> I have cutting oil..
[22:03:48] <anonimasu> :)
[22:04:04] <pfred1> aluminum is special
[22:04:08] <gezr> SWPadnos is correct, aluminum also has a tendency to stick to a hss endmill, an air blast with a water pickup line in most cases is enough to counteract a semi high speed operation
[22:04:11] <SWPadnos> how about antifreeze (like for a car), or other coolant?
[22:04:19] <gezr> water
[22:04:21] <gezr> is just fine
[22:04:31] <anonimasu> gezr: that'll make it rust..
[22:04:41] <gezr> its aluminum right?
[22:04:43] <anonimasu> the machine that is..
[22:04:43] <SWPadnos> yep - the propylene glycol is a little bit of a lubricant as well
[22:04:53] <SWPadnos> wipe it when you're done :)
[22:04:55] <gezr> not if he keeps it lubed up
[22:05:16] <gezr> anything other then water/air is going to create a mist he may not be able to deal with
[22:05:18] <pfred1> use antifreeze specially formulated for aluminum radiators :)
[22:05:28] <SWPadnos> true - the machine should be covered in oils anyway
[22:05:37] <anonimasu> yeah but the table..
[22:05:39] <pfred1> so should the operator!
[22:05:52] <gezr> and antifreeze is going to coat all sorts of stuff for the animals in the house to get a good licking
[22:05:58] <SWPadnos> anyway, get a spray bottle, and give a squirt every few seconds to keep the endmill cool
[22:06:06] <anonimasu> yeah.. I know it's gummy,,
[22:06:13] <SWPadnos> (gezr is right - use pure water)
[22:06:21] <gezr> its gummy because it melts while being cut
[22:06:28] <anonimasu> or isoprop alcohol ;)
[22:06:37] <pfred1> yeah that's why you stream it with compressed air to clear the chips
[22:06:39] <gezr> the fact its soft in terms of a material doesnt help
[22:06:42] <SWPadnos> water is cheaper
[22:06:46] <anonimasu> yeah..
[22:06:49] <pfred1> cheaper than air?
[22:06:59] <anonimasu> well, dosent matter now I am finished for today..
[22:07:09] <anonimasu> I'll cut lighter cuts at a higher speed.. instead..
[22:07:13] <gezr> you can use butter
[22:07:26] <pfred1> gezr how about whipped cream?
[22:07:28] <pfred1> kinky!
[22:07:40] <anonimasu> wont it sclale if I increase both speed and feed..
[22:07:43] <gezr> that may work anything to help pull the heat out of the chip the moment its formed
[22:07:47] <paul_c> f you have it, soluble oil
[22:07:55] <pfred1> really you need special tooling for aluminum
[22:08:01] <anonimasu> yep.. got that..
[22:08:34] <anonimasu> * anonimasu yawns
[22:08:45] <paul_c> No need for the screwball mixes then...
[22:08:50] <anonimasu> yep..
[22:09:06] <anonimasu> can get it off work for free.. as much as I need..
[22:09:23] <pfred1> anonimasu we have lots of air here
[22:09:29] <pfred1> it's about 50 miles htick or so ...
[22:09:33] <pfred1> thick even
[22:09:36] <robin_s> * robin_s got his press today
[22:09:55] <pfred1> robin_s printing seditious literature?
[22:10:15] <robin_s> pfred1: 50 tonne, 2m CNC pressbrake
[22:10:38] <robin_s> pfred1: I use the interent for printing seditiuos literature ;)
[22:10:45] <Imperator_> * Imperator_ wishes anonimasu good luck, and goes to bed
[22:10:55] <anonimasu> yeah night Imperator_
[22:11:00] <anonimasu> I am done milling for today
[22:11:01] <Imperator_> cu
[22:11:02] <robin_s> night ...
[22:11:12] <anonimasu> I'll continue tomorrow..
[22:11:15] <robin_s> anonimasu: made chips?
[22:11:24] <anonimasu> robin_s: yeah broke a endmill and almost another one..
[22:11:29] <robin_s> coo
[22:11:31] <anonimasu> lol
[22:11:32] <robin_s> on ally?
[22:11:35] <anonimasu> yeah
[22:11:43] <anonimasu> alu is nasty..
[22:11:46] <robin_s> 2 flute?
[22:11:50] <anonimasu> 3flute..
[22:11:54] <robin_s> hmmm
[22:12:05] <robin_s> gummed up huh?
[22:12:06] <anonimasu> I didnt know if I had the collets for my 2flute long slotdrills..
[22:12:08] <anonimasu> nope..
[22:12:16] <anonimasu> the first one took a too large bite..
[22:12:20] <robin_s> ahh
[22:12:22] <anonimasu> and the spindle stalled and broke..
[22:12:28] <robin_s> heh
[22:12:33] <anonimasu> broke the endmill..
[22:12:39] <robin_s> you G0'd it into the work?
[22:12:41] <paul_c> anonimasu: You using long series ???
[22:12:41] <anonimasu> it was clean the i hit it out of the cut it took..
[22:12:56] <anonimasu> paul_c: I have for milling plastics..
[22:13:12] <anonimasu> although I havent tried them yet
[22:13:31] <paul_c> Long series, you would need to reduce the feedrate by 50% or more.
[22:13:40] <anonimasu> hm, ok
[22:13:57] <anonimasu> 8mm slotdrill..
[22:14:00] <anonimasu> 2flute
[22:14:05] <robin_s> thats more like it
[22:14:13] <anonimasu> is that better for cutting alu with?
[22:14:17] <anonimasu> although it's long ones.
[22:14:18] <robin_s> sounds it
[22:14:31] <robin_s> best is a single flute :)
[22:14:35] <anonimasu> 4cm flutes ;)
[22:14:36] <robin_s> solid tungsten
[22:14:39] <anonimasu> lol
[22:14:41] <anonimasu> cheap ones
[22:14:46] <robin_s> assuming you have enough revs
[22:14:58] <robin_s> actully,
[22:15:23] <robin_s> plain old tungsten tipped 'straight' router cutters work ok
[22:19:44] <les> ah you're back
[22:50:06] <anonimasu> hm.. I guess I'll make another try tomorrow
[22:51:09] <les> heading home?
[22:54:52] <anonimasu> oh I am already home
[22:55:29] <anonimasu> hmm.. I am curious on how much I can get the feedrates up..
[22:55:50] <anonimasu> 60 minutes for pocketing a 2d part in alu feels like forever..
[22:56:15] <anonimasu> maybe I could do 600mm/min and lighter cuts..
[22:58:05] <anonimasu> but the part will still take about as long to make..
[22:58:13] <robin_s> hmm
[22:58:28] <robin_s> 0.003" per tooth
[22:58:44] <robin_s> you have, 3 flutes?
[22:58:48] <robin_s> 3000 rpm?
[22:59:00] <anonimasu> yeah..
[22:59:01] <anonimasu> or more.
[22:59:02] <robin_s> 0.009" per rev
[22:59:15] <robin_s> 27" per minute
[22:59:25] <robin_s> thats what, 600mm minute @300rpm
[22:59:35] <robin_s> 3000rpm
[22:59:40] <anonimasu> 1000mm/min now..
[22:59:46] <anonimasu> 0.05 stepdown
[23:00:11] <robin_s> sounds about right on feeds
[23:00:17] <robin_s> what cutter dia?
[23:00:20] <anonimasu> 6mm endmill..
[23:00:21] <anonimasu> 3 flute
[23:00:40] <robin_s> you could go 0.5 dia steppdown
[23:00:44] <robin_s> no worries
[23:01:05] <robin_s> so 3mm steps would not be unreasonable
[23:01:17] <anonimasu> my mill cant cope with that..
[23:01:20] <robin_s> 3 flutes might clog though
[23:01:23] <anonimasu> that'll be too high load and stall the spindle..
[23:01:26] <robin_s> right
[23:01:36] <robin_s> I had a 3hp spindle on my router
[23:01:42] <anonimasu> I have too little torque to make it work..
[23:01:59] <Dmess> 3 flute is most rigid tool for the size of the chip pocket
[23:02:11] <robin_s> at 12000 rpm eith a 6mm single flute ...
[23:02:23] <anonimasu> hehe
[23:02:35] <robin_s> Dmess: in alluminium t3 flutes is not optimal, needs mreo chip clearance
[23:02:38] <anonimasu> yeah..
[23:02:43] <anonimasu> this is 6063
[23:02:45] <Dmess> i had an F-mach toshiba minimum rpm was 8000 went to 60 0000
[23:02:52] <robin_s> single flute works best at high rpm
[23:03:05] <robin_s> make chips, not dist
[23:03:10] <robin_s> thats the key
[23:03:10] <robin_s> dust
[23:03:12] <anonimasu> yeah..
[23:03:17] <Dmess> get your hand on an international minicut end mill
[23:03:26] <anonimasu> hm will 3000rpm at 1000mm/min work..
[23:03:39] <robin_s> 0.003 per chip
[23:03:43] <robin_s> "
[23:03:50] <anonimasu> 0.127
[23:03:50] <anonimasu> mm
[23:04:04] <robin_s> I dont know why I do chips in inches
[23:04:13] <Dmess> believe it or not ive run 350 rpm and 120 ipm in 4140 prehard
[23:04:39] <robin_s> big chips
[23:04:45] <anonimasu> it sounds too much..
[23:04:59] <Dmess> using a hitatchi cutter on a toshiba mill.....12 per tooth...
[23:05:06] <Dmess> 0.12 per tooth
[23:05:09] <anonimasu> 0.07 = 6000rpm
[23:05:46] <Dmess> trade show sjow em up deal...
[23:05:49] <robin_s> my crane driver today was a compleat tosser
[23:06:19] <anonimasu> hehe
[23:06:29] <robin_s> brought the press
[23:06:31] <anonimasu> * anonimasu is curious if this will work..
[23:06:38] <Dmess> i sti;; have some of the sixes and nines from that show...
[23:06:43] <robin_s> slung on uneven lifting slings
[23:06:55] <robin_s> so when he lifted it .. all the oil pissed out
[23:07:06] <robin_s> as it tipped up
[23:07:09] <Dmess> nice...
[23:07:26] <robin_s> wont use him again
[23:07:41] <Dmess> you do installations??
[23:07:52] <anonimasu> :)
[23:07:55] <robin_s> not as such
[23:08:07] <robin_s> justmoving a press to my place
[23:08:25] <Dmess> big one??
[23:08:35] <robin_s> nah
[23:08:38] <robin_s> tiny
[23:08:51] <robin_s> Amada Promecam 2m / 50 tonne
[23:08:57] <robin_s> weighs about 5t
[23:09:02] <Dmess> nice machines..
[23:09:15] <robin_s> not my nicest machine
[23:09:41] <robin_s> top of the list is my Trumpf laser :)
[23:09:47] <Dmess> but its yours...
[23:10:13] <robin_s> well,
[23:10:16] <robin_s> its sort of mine
[23:10:23] <robin_s> technically, its my mate Andys
[23:10:29] <robin_s> but its in my unit
[23:10:38] <robin_s> now :)
[23:10:38] <Dmess> i see
[23:10:52] <Dmess> thump thump thump
[23:11:22] <robin_s> http://www.rapidcut.co.uk/images/LY2500.jpg
[23:11:22] <robin_s> thats mine :)
[23:12:21] <robin_s> mm, the press just goes <squeeeeeeze> bend
[23:12:25] <robin_s> almost silent
[23:12:39] <robin_s> the punch .. now .. that went THUMP THUMP THUMP
[23:13:20] <Dmess> nice laser... uses trumpf control>>
[23:13:27] <robin_s> Bosch
[23:13:42] <Dmess> hmm
[23:13:48] <robin_s> B220 series control
[23:14:07] <Dmess> pc based??
[23:14:13] <robin_s> hell no
[23:14:43] <Dmess> hey heidenhein is ... now
[23:14:52] <robin_s> on a mill?
[23:15:05] <Dmess> yes..
[23:15:21] <Dmess> siemens 840 d
[23:15:34] <Dmess> has 2 pIII cpu's
[23:15:39] <robin_s> coo
[23:16:05] <Dmess> one for operator interaction one for the cnc
[23:16:11] <robin_s> right
[23:16:16] <robin_s> good chaoice
[23:16:21] <robin_s> choice
[23:16:36] <robin_s> this Bosch has a big CNC lump
[23:16:52] <robin_s> and a seperate "intelligent VDU"
[23:17:21] <Dmess> as with most dedicated cnc controls
[23:17:28] <robin_s> yep
[23:17:34] <robin_s> only snag,
[23:17:46] <robin_s> all the documentation is in german
[23:18:09] <Dmess> lovely... older siemens used to be that way too
[23:18:19] <robin_s> well, its not all in german
[23:18:30] <robin_s> we have some notes from its previous owner
[23:18:38] <Dmess> are the #'s in german??
[23:18:52] <robin_s> in ... Dutch
[23:19:33] <Dmess> LOL we had one machine land from japan for a show.... it had a japanese control
[23:19:39] <robin_s> noce
[23:19:41] <robin_s> nice
[23:19:55] <robin_s> kanji?
[23:20:00] <Dmess> we ran it for the show and told ppl the english one was an option..
[23:20:09] <robin_s> heh
[23:20:12] <robin_s> was it?
[23:20:23] <Dmess> kanji and 16 bit floppy formats...
[23:21:20] <Dmess> had to swap out one of the japanese engineers floppys into my box to get programs into the machine on the floor
[23:21:39] <robin_s> ick
[23:21:58] <robin_s> last big show I went to was mach2004 in the UK
[23:22:07] <robin_s> www.mach2004.com
[23:22:08] <Dmess> trade shows SUCK the big one for application engineers
[23:22:29] <robin_s> yeah, I can imagine
[23:22:41] <Dmess> never enough time and 3 too many machines
[23:22:46] <robin_s> "will your machine do this?"
[23:23:06] <robin_s> <insert partly formes description of complex part>
[23:23:35] <Dmess> will it do it in 1 minute... hmm lets see 500lb slug on... 45 lbs finished sculptured part
[23:23:39] <anonimasu> lol
[23:23:48] <anonimasu> kanji is tough
[23:23:49] <robin_s> infact, I enjoyed mach2004 so much ... I bought mach2006.com :)
[23:24:04] <Dmess> sure but the CLAPPER option is a might costly..
[23:25:09] <Dmess> i never learned kanji i just remembered what did what from the english control
[23:25:35] <robin_s> heh
[23:26:06] <Dmess> im a hand over hand kinda guy on alot of them
[23:26:12] <robin_s> "click here to home the tool at full speed straight through the work envelope"
[23:26:33] <anonimasu> lol
[23:26:44] <robin_s> aahm, a demo engineer .. :)
[23:26:46] <anonimasu> frrrrrrrp
[23:27:08] <Dmess> Z - y x by retatded default
[23:27:46] <Dmess> demo eng is not my favorite title... but i have demod my fair share
[23:27:49] <robin_s> I saw the Mazak stand ... that was amazing
[23:28:03] <robin_s> that was a HUGE machine
[23:28:33] <Dmess> it was at CMTS too when their big un blew a belt trying to keep up to me..LOL
[23:29:03] <Dmess> i bet i had 200 ppl around 1 machine at 1 point..
[23:29:19] <robin_s> coo
[23:29:35] <Dmess> everything sounding like mildly controlled crashes
[23:30:00] <robin_s> if the tool survives, i guess its a success
[23:30:05] <pfred1> I've attracted a crowd on an NYC sidewalk plating Robotron
[23:30:06] <Dmess> made 2000L of chips... just for shits and giggles...
[23:30:09] <pfred1> playing even
[23:30:31] <robin_s> heh
[23:30:36] <Dmess> 2000 lbs
[23:30:47] <pfred1> it was funny when i just walked away from the game at like 2 million
[23:30:58] <robin_s> whats robotron?
[23:31:11] <Dmess> toshiba mpf series
[23:31:13] <pfred1> old Williams game sequel to Defender
[23:31:19] <robin_s> right
[23:31:22] <robin_s> I remember defender
[23:31:47] <Dmess> i dont wanna remember the $$$ i put into defender
[23:31:48] <robin_s> and my fave, "firebird"
[23:32:03] <pfred1> I was never any good at defender was OK at Robotron though
[23:33:20] <Dmess> i had an old 486 with emu for all the old games
[23:33:22] <SWPadnos> totally different games
[23:34:01] <Dmess> till the kids started using it...and then the mommy board said she was done
[23:34:09] <pfred1> xmame
[23:34:39] <Dmess> mame...thats it.. is xmame run in x too??
[23:35:08] <pfred1> it's a game emulator
[23:36:04] <Dmess> yes
[23:36:19] <pfred1> not so sure how easy it is to get ROMs for it anymore
[23:36:39] <pfred1> but Robotron doesn't translate to keyboard controls very well :(
[23:36:48] <pfred1> Joist is really cool on a PC
[23:36:53] <pfred1> Joust even
[23:37:12] <Dmess> that was a good one... Quix too
[23:37:30] <pfred1> I got a ton of ROMs someplace on a CD
[23:37:39] <robin_s> remember the funny story behind "donkey kong"?
[23:38:24] <robin_s> it was supposed to be "monkey kong" .. but the firm that sprayed the cabinets screwed up
[23:38:35] <pfred1> ha ha!
[23:38:41] <robin_s> in the end, it was easier to change the rom than change the cabinets
[23:38:42] <Dmess> really..LOL
[23:38:44] <pfred1> Engrish strikes again!
[23:38:45] <robin_s> really
[23:39:03] <pfred1> http://www.engrish.com/
[23:39:09] <robin_s> you may have noticed though, it had a lot of monkey, but not much donkey inthe game
[23:39:45] <Dmess> well i never knew that...LOL
[23:40:59] <robin_s> the game's name evolved was that it was supposed to be "Monkey Kong", but due to a barely legible fax transmission, the screenprinters created thousands of pieces of artwork that read "Donkey Kong" instead. Since the manufacturers were in a rush to get the game released, they opted to change the game's title rather than wait for the artwork to be reprinted.
