[00:02:11] <frallzor> hey guys, im playing around with artcam and im about to make the g-code but there is alot of postprocessors to make code for, what is considered a good pp thats uses pretty common code?
[00:03:33] <clip9> The G-Code one works fine.
[00:05:39] <frallzor> *.tap one?
[00:05:43] <clip9> yep
[00:05:52] <frallzor> only issue is it wont allow toolchange
[00:06:30] <frallzor> but who cares, Its better this way I see, multiple jobs for differente passes =)
[00:06:55] <toastyde1th> m0?
[00:07:12] <toastyde1th> what kind of postprocessor can't handle toolchanges
[00:07:36] <frallzor> for some reason both the G-code *.tap and fanuc in artcam
[00:07:56] <toastyde1th> can't handle t# m6?
[00:08:08] <clip9> You can just add it to the .con file.
[00:08:14] <clip9> It's pretty easy.
[00:08:21] <frallzor> .con?
[00:08:34] <clip9> yeap it's in the artcam directory somewhere.
[00:08:39] <frallzor> ah let me cheack
[00:09:59] <frallzor> *check
[00:10:33] <frallzor> where do I put in that then?
[00:11:39] <clip9> Eh.. I don't remember. but i think i just copied from a .conf that did support toolchange. Like the one for mach3 i think.
[00:11:44] <clip9> err
[00:11:46] <clip9> *.con
[00:12:36] <toastyde1th> I was boring out a 5" copper bar into a 5" copper tube today
[00:12:46] <toastyde1th> i learned about the chipbreaking cycle, weird stuff
[00:12:53] <toastyde1th> like watching a cnc jackhammer go to work
[00:18:54] <frallzor> hmm is there a material that has the look of metal but alot easier to machine?
[00:19:14] <clip9> Al?
[00:19:15] <SWPadnos> softer metal
[00:19:32] <toastyde1th> aluminum is about the easiest thing that i can think of that looks like metal (by virtue of being so)
[00:19:36] <toastyde1th> so i am with clip9
[00:20:19] <frallzor> dont thing my gantrymill can do that
[00:20:21] <toastyde1th> 2024 or 7075
[00:20:21] <frallzor> *k
[00:21:58] <toastyde1th> then i'm not sure what to tell you other than to invest in some paint or something
[00:22:19] <clip9> hm.. must be a tiny mill if it can't handle aluminium.
[00:22:56] <frallzor> well you try and do 50mm Al with a diy gantrymill ;)
[00:22:58] <clip9> You don't need much power if you have good cutters and use some cutting fluid.
[00:23:42] <clip9> Just do it _slow_ :P
[00:24:06] <frallzor> ill just stick with wood =)
[00:25:16] <clip9> http://svarteper.com/images/spa-thomas.jpg
[00:25:20] <clip9> Al is cool.
[00:27:58] <frallzor> * frallzor wants his last 2 pieces of metal to finish his mill
[00:46:37] <tom3p> lead is easier than alum
[00:47:16] <clip9> haha
[00:47:20] <tom3p> and if u f it up. you can melt it into as block again
[00:47:40] <clip9> Gallium is better.
[00:47:48] <clip9> Atleast it's not toxic.
[00:48:34] <clip9> Only problem you have to keep the workpeice below 30 degrees C or it melts :P
[00:49:33] <tom3p> have fun, gotta go
[03:12:28] <tomp> tomp is now known as tom3p
[03:13:50] <tom3p> re: awalin's notes on simple tp... "if the end of the previous segment points in the same direction as the start of the next one there is no need to stop in the middle"
[03:13:50] <tom3p>  should that be 'in between' ? as in between 2 line/circles(s) ?
[03:14:16] <tom3p> meaning ~' if tangential, then dont hesitate' ?
[03:16:42] <fenn> simple tp makes sure it is able to stop at the end of every segment pair
[03:16:56] <fenn> i guess this extends that to the next segment if they're tangent/colinear
[03:18:56] <tom3p> 'able to stop' and 'no need to stop' are not same thing. does it stop if tangent/colinear? is a square with nice radii in corners a series of jerks at 100ipm, or a nice motion?
[03:19:18] <tom3p> heh ;) nice... hard to describe
[03:22:27] <tom3p> in wedm we always programmed what we called tangential, the end vector was perfect to next motion, we never ever had line/line motions, always coded arcs between lines, even arc between non 'tangential' arcs.
[03:22:28] <tom3p> of course our top velocity was slow, but we never saw velocity vary.
[04:03:29] <L84Supper> anyone know what the Parker Gemini servo drives use for a cpu and OS?
[09:51:24] <numen> hi
[10:22:03] <piasdom_> g'mornin all
[13:07:47] <Valen1> Valen1 is now known as Valen
[14:09:45] <piasdom> in axis,it shows me the limit when i load the files.but it's rounding off to 2 places,can that be changed to 3 or 4 places?
[14:25:27] <piasdom> using inches
[14:26:39] <SWPadnos> line 700 in axis.py has the format string
[14:26:48] <SWPadnos> fmt = vars.metric.get() and "%.1f" or "%.2f"
[14:27:03] <SWPadnos> change the last string from "%.2f" to "%.3f"
[14:27:29] <SWPadnos> I don't know if there are any other necessary changes
[14:28:27] <piasdom> SWPadnos; THANKS
[14:28:39] <SWPadnos> oh hmm. that's in the most current git version. The line number may be different for you - look for the function "redraw"
[14:28:41] <SWPadnos> sure
[14:28:49] <SWPadnos> (but try it before you thank me ;) )
[14:29:18] <piasdom> hahahahhaha........OK
[14:30:51] <cradek> piasdom: in what way are you using those numbers, so that much precision is useful?
[14:31:51] <piasdom> cradek; nothing, just use to seeing 3 plc
[14:32:09] <piasdom> * piasdom gets confused easy :)
[14:33:23] <cradek> oh ok - I just use them for locating the program on the workpiece, where not much precision is needed - I was wondering if you had a different use.
[14:33:52] <piasdom> :)
[14:48:06] <piasdom> i found this: http://paste.org/pastebin/view/10033
[14:48:50] <SWPadnos> yep. that looks like the line
[14:49:15] <piasdom> it says 1 or 2 change 2 to 3 ?
[14:49:22] <SWPadnos> yep
[14:49:26] <piasdom> thanks
[14:49:34] <SWPadnos> and 1 to 2 if you want metric to show with 2 decimals
[14:50:20] <piasdom> cool :)
[15:40:07] <piasdom> anyone know why sudo is unable to resolve host?
[15:47:46] <piasdom> never mind...it started working....thanks
[15:59:58] <piasdom> SWPadnos: that was it ...working great.....THANKS
[16:00:21] <SWPadnos> excellent
[17:32:25] <Jymm> * Jymm can picture SWPadnos saying "excellent" in an evil take-over-the-world kinda voice
[17:32:41] <SWPadnos> one MILLION dollars!!! muahahahahahaha!
[17:33:36] <Jymm> lol
[17:38:47] <Jymm> SWPadnos: I dont know what I got myself into today... freind reffered me to a firend of his that is starting a business and needed IT help, well the job is much bigger than I was lead to believe.
[17:38:59] <SWPadnos> excellent
[17:39:08] <SWPadnos> as long as the salary is too :)
[17:39:21] <SWPadnos> and/or the stock options
[17:39:54] <Jymm> no that that big of a company
[17:40:04] <SWPadnos> YET!
[17:41:12] <skunkworks656> isn't that the apple story - when the just started out - they paid someone in stock options..
[17:42:15] <SWPadnos> Mcdonalds
[17:42:41] <SWPadnos> the secretary got stock options in the early years, and was worth some millions by the time she retired
[17:45:10] <skunkworks656> nice
[17:58:45] <BJT-Work> Yea! my new boring bar is in :)
[17:58:55] <SWPadnos> how boring
[17:59:15] <SWPadnos> hmmm. I guess I need to eat
[17:59:15] <BJT-Work> 6" OAL
[17:59:23] <SWPadnos> must be a thick one
[17:59:36] <BJT-Work> 1/2"
[17:59:48] <archivist> I did bore a .8 mm hole the other day
[18:01:53] <BJT-Work> I had to squint to the the dot in front of the 8
[18:02:06] <BJT-Work> must have been a tiny boring bar
[18:02:19] <archivist> I made it
[18:02:55] <archivist> grind most from a 1/2" hss bit
[18:03:56] <archivist> older eyes means I have to turn under a microscope
[18:05:53] <BJT-Work> I have 2 or 3 Optivisors :)
