[00:06:18] <eztam> hi atmega
[00:10:43] <foxtrot> hmm
[00:10:55] <foxtrot> i need a good workmedium that wont eat all my bits
[00:11:03] <foxtrot> is there some way i can make slabs of plastic
[00:11:08] <foxtrot> or something
[00:18:37] <alex_chally> foxtrot, yes!
[00:18:45] <alex_chally> we were talking about it the other day, let me find the link
[00:19:06] <alex_chally> foxtrot, http://repraplogphase.blogspot.com/2010/06/nice-recipe-for-machineable-wax.html
[00:19:40] <alex_chally> it is 4:1 paraffin wax: grocerie bags
[00:19:41] <alex_chally> :D
[00:19:46] <alex_chally> by weight obviously
[00:19:58] <alex_chally> I have not actually made any yet, but I am going to
[00:20:41] <foxtrot> wait, you meant like the grocery bags that me and everyone else in the world puts in a cabinent under the sink?
[00:20:52] <alex_chally> yeah dude
[00:20:54] <foxtrot> i can use those and not just save them up just to throw out after years
[00:21:11] <alex_chally> "Most plastics are usually marked with LDPE or HDPE and have a number 4 or 2 (respectively) located on recyclable polyethylene."
[00:21:34] <foxtrot> the deep fryer part sucks tho
[00:21:35] <alex_chally> and paraffin wax, but that stuff is cheap
[00:21:54] <foxtrot> i was hoping to use like a 9"x9" brownie pan or something
[00:22:02] <alex_chally> foxtrot, use your oven
[00:22:11] <alex_chally> you can set the temp
[00:22:21] <alex_chally> make sure to be VERY well ventalated
[00:23:01] <atmega> you seem a little confused by the concept.
[00:23:04] <alex_chally> or just a pot on a stove and a thermometer
[00:48:34] <Guest55960> Guest55960 is now known as Brian91834821
[00:48:47] <Brian91834821> Brian91834821 is now known as BrianInTampa
[00:51:18] <BrianInTampa> I am trying to compile EMC for the first time, and I am not having sucess with the wiki method, anyone care to offer some help?
[00:52:39] <Jymmm> Why compile it?
[00:53:04] <BrianInTampa> Because I want to test some code changes
[00:53:25] <BrianInTampa> I already have a working EMC syste,
[00:53:36] <Jymmm> ah
[01:04:30] <skunkworks_> skunkworks_ is now known as skunkworks
[01:05:47] <skunkworks> BrianInTampa: what problems are you running into?
[01:07:13] <BrianInTampa> Well, let me start by saying that I am not very familer with Linux.
[01:07:30] <BrianInTampa> I know enough to get around, but I don't know it like the back of my hand
[01:08:27] <BrianInTampa> So, I am following the Wiki method to compile
[01:08:28] <BrianInTampa> $ cd src
[01:08:29] <BrianInTampa> $ ./autogen.sh
[01:08:29] <BrianInTampa> $ ./configure --enable-run-in-place --enable-build-documentation
[01:08:29] <BrianInTampa> $ make
[01:08:29] <BrianInTampa> $ sudo make setuid
[01:08:52] <BrianInTampa> when I execute autogen, it complains at line 6 about not being able to find autoconf
[01:11:48] <skunkworks> start from the begining. did you use these directions?
[01:11:51] <skunkworks> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Getting_the_source_with_git
[01:12:42] <skunkworks> actually - start here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_with_EMC2_package_already_installed
[01:12:48] <skunkworks> at 2.1.2
[01:18:26] <BrianInTampa> Well, I did all that the other day, I suppose I should double check to make sure everything wnet ok
[01:19:48] <BrianInTampa> Maybe I missed somehting there, I'l know after it gets done downloading...
[01:20:13] <BrianInTampa> Perhaps anyone can be guilty of a blond moment...
[01:21:40] <BrianInTampa> blonde?
[01:21:44] <BrianInTampa> heh...
[01:24:25] <BrianInTampa> Hmm
[01:25:10] <BrianInTampa> the build-dep got through most of it, but failed at the end, the build-essential failed immediately
[01:25:31] <BrianInTampa> 404 Not Found errors.
[01:25:52] <BrianInTampa> IP 91.189.88.46 port 80
[01:29:36] <BrianInTampa> skunk, did you see what I came up with?
[01:30:11] <skunkworks> hold on
[01:31:43] <skunkworks> hmmm - what os are you using?
[01:31:58] <skunkworks> is it hardy or lucid or?
[01:32:10] <BrianInTampa> 8.04
[01:32:14] <skunkworks> hmm
[01:32:14] <BrianInTampa> Hardy
[01:32:35] <BrianInTampa> It was installed from the live CD
[01:32:41] <BrianInTampa> pretty vanilla
[01:32:52] <skunkworks> I wonder if one of the dependency sites is down.
[01:33:00] <BrianInTampa> thats what it seems like
[01:33:02] <skunkworks> (I cannot test it here atm)
[01:33:06] <BrianInTampa> ok
[01:33:43] <BrianInTampa> I don't think it is anything on my side, everything else seems to work fine
[01:33:50] <BrianInTampa> only a few of the sites fail to connect
[01:34:07] <BrianInTampa> I dunno..
[01:34:35] <skunkworks> but it sounds like maybe you didn't do the sudo apt-get build-dep emc2 or sudo apt-get install build-essential autoconf
[01:34:41] <skunkworks> initially?
[01:35:00] <BrianInTampa> Well, I am 99% sure I did, but it may have failed then too
[01:35:08] <skunkworks> ah
[01:35:30] <BrianInTampa> I can't remember for 100% certain if the completed sucessfully
[01:35:36] <BrianInTampa> they
[01:35:36] <skunkworks> I don't know - do you need to enable the universe in the synaptic package manager? or is it already?
[01:35:53] <BrianInTampa> Dunno, lemme see what I can figure out
[01:37:25] <skunkworks> system - > administration -> synapitic package manager -> setting -> repositories (I think)
[01:39:46] <BrianInTampa> Found it, universe was checked.
[01:40:08] <BrianInTampa> I check a few packages in another tab and reloaded...
[01:40:34] <BrianInTampa> I am running sudo apt-get build-dep emc2 again...
[01:41:14] <BrianInTampa> looks like in completed this time!
[01:42:50] <BrianInTampa> It seems to be compiling now
[01:42:54] <BrianInTampa> word.
[01:43:03] <skunkworks> sweet !
[01:43:13] <BrianInTampa> skunk, yooda man!
[01:44:19] <BrianInTampa> Right after it completes, I'm off to go see 'The Expendables'
[01:45:06] <skunkworks> heh - is that out today?
[01:45:37] <BrianInTampa> Apparently it is here...
[01:45:43] <BrianInTampa> Starts at 10:15
[01:45:47] <skunkworks> biab - have fun!
[04:14:00] <Birdman3131> Birdman3131 is now known as birdman3131|zzzz
[04:43:51] <Guest592> Hello I see that using EMC to control a CMMM is listed as a use, but i dont know if anyone has? Does anyone here know a cmm running emc?
[04:44:29] <cradek> I measure stuff with a probe in my mill all the time
[04:44:51] <cradek> especially bore diameters
[04:45:21] <Guest592> did you simply touch off or does do you have it setup to calculate hole diameters and locations?
[04:46:21] <cradek> actually here's a video of how it looks: http://www.youtube.com/watch?v=eWitrmtqZ7I
[04:50:22] <elmo40> have you compared the probed values to micrometer values?
[04:50:42] <cradek> bore gauge standards yes
[04:50:51] <cradek> it matches to .0001 inch
[04:50:59] <cradek> this machine has truly excellent ball screws
[04:51:18] <elmo40> so it seems!
[04:51:30] <elmo40> love the renishaw, excellent probes.
[04:51:38] <elmo40> how much are the tips for them?
[04:52:02] <cradek> I have a .74890 ceramic standard that I test with occasionally
[04:52:16] <cradek> oh $20-40, not bad
[04:52:26] <cradek> I have not broken one yet :-)
[04:54:05] <Guest592> so you wrote a selection of routines for the various shapes that you need to inspect from time to time?
[04:54:26] <cradek> Guest592: http://timeguy.com/cradek/01262579508
[04:55:02] <cradek> elmo40: #1009=[[[#1007+#1008]/2]-0.000254]
[04:55:49] <cradek> this is in my calibrated probing routine. due to various errors (?) it gives me results .00025 too big. hard to say what the causes are, but I can measure it and correct for it by checking against standards
[04:56:34] <cradek> it's perfectly repeatable - often if I probe several times in a row I'll get exactly the same results (micron resolution)
[04:56:51] <cradek> ... even if I move the machine and put it back
[04:57:21] <elmo40> have you adjusted the screws to center the tip?
[04:57:49] <cradek> yes but it's currently .0007 off - you can see it in that video
[04:58:18] <cradek> (finding the center of a hole the machine just bored)
[04:58:38] <cradek> it's hard to get it perfect - better to measure the error and compensate in software
[05:12:42] <elmo40> being consistent, then sure, compensation with software is a good way to deal with it
[05:12:56] <elmo40> but it baffles me why so much. that is almost one thou.
[05:13:44] <elmo40> I know at work we can probe a part 5 times and get 5 different values within +/- 0.0002
[05:13:59] <elmo40> I think the probing macro moves too fast.
[05:14:45] <cradek> with emc it only checks the probe every servo cycle. so if you want full resolution you have to move no more than one encoder count per servo cycle.
[05:15:10] <cradek> for me that's 1 micron/microsecond = 2 inches/min
[05:15:23] <cradek> er micron/millisecond
[05:15:46] <cradek> I think I actually do the final probe at .5 inch/min
[05:16:22] <cradek> doesn't have to move very far at that low speed because it has a quite close estimate first
[05:23:29] <cradek> goodnught
[05:23:30] <cradek> i
[05:25:55] <elmo40> night
[05:26:52] <IchGuckLive> good morning from wunderfull sunny Germany
[05:27:04] <IchGuckLive> ichudov: ?

[07:16:12] <archivist> thats nice awallin :)
[07:24:33] <awallin> it's getting there...
[07:25:19] <awallin> still some gaps in the surface. not sure where they come from
[07:38:04] <danielfalck> awallin: that's great

[14:17:15] <Jymmm> alex_joni: On my laser engraver I need to have "air assist" - A stream of clean air blowing on/at the point where the material being cut, maybe 35-50 psi max. They want $1200 for some brackets and tubing (no compressor, dryer, regulator, etc included).........
[14:19:28] <Jymmm> alex_joni: I need to fabricate a way to to direct the air a specific direction, can you think of something whereI can adjust the direction of airflow, be it 90 deg straigt down, or 80 deg facing towards the rear, etc. I'm kinda looking at 1/8" metal tubing, but open to suggestions.
[14:20:00] <alex_joni> is it always directed in the same direction?
[14:20:06] <alex_joni> or does it need to move?
[14:21:06] <alex_joni> (you can probably use some of those tubings that are used for coolant on mills)
[14:21:44] <alex_joni> http://web.tradekorea.com/upload_file2/sell/96/S00011896/coolant_hose_.jpg
[14:25:02] <Jymmm> Those are probably WAY too big, hang on....
[14:26:22] <Jymmm> alex_joni: Take a look http://filebin.ca/ajtheo/AirAssistInstallationInstructions.pdf
[14:27:16] <Jymmm> I'm even thinking 1/8" may be too big
[14:29:33] <Jymmm> alex_joni: I need to come up with EVERYTHING you see in that doc.
[14:30:20] <Jymmm> within the main cabinet, not the control box.
[14:45:47] <MattyMatt> Jymmm, you can put any nozzle on those coolant tubes
[14:46:23] <Jymmm> MattyMatt: No, I mean it may be too heavy to mount on the moving laser head.
[15:11:18] <alex_joni> Jymmm: then how about those tubes used for printer ink ?
[15:11:22] <alex_joni> too thin?
[15:12:10] <Jymmm> alex_joni: I'm not familure with the ones you're talking about.
[15:13:58] <alex_joni> http://www.bikudo.com/product_search/details/128017/epson_stylus_t11_ciss.html
[15:14:58] <Jymmm> alex_joni: Heh, yeah a lil too thin I think =)
[15:16:06] <Jymmm> alex_joni: It looks like they are using 1/8" tubing (which I have to figure out how to route in the machine with no guides), to a metal tube
[15:28:46] <IchGuckLive> Hey folks i yust finsiht the 4th of6 item to the Pocket.py i try to programm to emc axis
[15:31:11] <IchGuckLive> now in full working mode is Circular Pocket Spiral -Recktengular pocket Spiral - parallel pocket Zero line CW and also CCW

[17:31:35] <IchGuckLive> hi everyone
[17:35:50] <IchGuckLive> ichudov: ?
[18:01:49] <DaViruz> http://daviruz.meeep.net/buschcncnf1/DSC_0117.jpg
[18:01:56] <DaViruz> my new vertical mill, en route!
[18:04:19] <MattyMatt> fully laden :)
[18:08:18] <IchGuckLive> where are the safty belts ?
[18:09:58] <DaViruz> they are there, just not very visible
[18:10:06] <DaViruz> not unlike my reply to you
[18:22:36] <ichudov> I bought at a garage sale a USB joypad: Saitek P880 Dual Analog pad. Could I use it for EMC2? If not what joypad would you recommend?
[18:23:20] <ichudov> DaViruz: Impressive mill, post more pix
[18:23:32] <DaViruz> http://daviruz.meeep.net/buschcncnf1/DSC_0114.jpg
[18:23:43] <DaViruz> http://daviruz.meeep.net/buschcncnf1/DSC_0113.jpg
[18:23:49] <DaViruz> pretty much all i have
[18:23:59] <ichudov> Are you keeping the Sinumerik control?
[18:24:01] <ichudov> Wow
[18:25:50] <DaViruz> i'm not sure
[18:26:08] <DaViruz> if i can get it to work again i might
[18:26:14] <DaViruz> otherwise i'll emc2 it
[18:26:32] <DaViruz> (i might do that regardless)
[18:27:00] <ichudov> Have you done any EMC2 before or is this your first?
[18:27:44] <DaViruz> i have a smaller mill which is emc2 controlled
[18:28:18] <ichudov> I see. I personally like EMC over any old VCR style controls
[18:28:25] <ichudov> Awesome mill BTW
[18:28:31] <ichudov> how much did you pay
[18:28:54] <DaViruz> way too little, $1000
[18:29:05] <ichudov> I hate you!
[18:29:10] <ichudov> great price
[18:29:18] <DaViruz> yeah i'm almost ashamed :)
[18:29:25] <ichudov> Was that an auction or what? Was it described as working?
[18:30:08] <DaViruz> classified, described as working
[18:30:17] <ichudov> GREAT DEAL!
[18:30:32] <DaViruz> which it probably is, except that it's ┬┤been left unconnected for too long so the plc program and machine data is gone
[18:30:41] <ichudov> Battery dead?
[18:30:45] <DaViruz> yeah
[18:30:59] <DaViruz> the manufacturer will send me the files, at another $1000..
[18:31:07] <ichudov> Scary
[18:31:11] <ichudov> Who is the mfr
[18:31:19] <DaViruz> busch
[18:31:50] <DaViruz> never heard of them before i saw this machine, and it seems they are out of business now
[18:32:27] <ichudov> You are still way ahead. I am personally really glad that my Heidenhain control was dead. I shudder at the thought that I would never use EMC.
[18:33:08] <ichudov> I sold the control and it paid my cost for the milling machine
[18:33:17] <ichudov> even though it was bad and so described on ebay
[18:46:46] <DaViruz> ichudov: maybe the emc2 panel thingy i built will fit into the existing operator panel :)
[18:46:49] <DaViruz> http://daviruz.meeep.net/gallery2/v/eye-fi-dump/IMG_1856.JPG.html
[18:50:04] <ichudov> Looks cute, how did you build it?
[18:50:31] <DaViruz> http://daviruz.meeep.net/gallery2/v/eye-fi-dump/IMG_1859.JPG.html
[18:50:33] <DaViruz> the guts
[18:52:54] <ichudov> very nice.
[19:49:44] <ichudov>
[20:23:44] <Jymmm> DaViruz: How do you like your Eye-Fi?
[20:24:15] <Jymmm> DaViruz: Nice job on the cabinet too!
[20:25:43] <frallzor> im dying here, I want a pcb layout to g-code
[20:25:50] <frallzor> but I cant get it going as I want
[20:26:04] <frallzor> bloody postscript files
[20:26:18] <Jymmm> frallzor: ?
[20:26:43] <frallzor> the board layout is in a postscript file
[20:26:52] <Jymmm> ok
[20:26:58] <frallzor> and I cant figure out how to solve it the best
[20:27:16] <Jymmm> convert it to DXF
[20:27:56] <Jymmm> or PS to gcode http://www.chiark.greenend.org.uk/~alanb/ps2gc.html
[20:28:11] <frallzor> Im running win where I am now :)
[20:28:40] <Jymmm> frallzor: Sucks to be you =)
[20:30:51] <Jymmm> frallzor: download an nix iso and install it =)
[20:32:00] <frallzor> pdf to dxf works too
[20:32:13] <frallzor> but I only get shitty linework then
[20:32:17] <frallzor> useless
[20:32:26] <Jymmm> frallzor: http://www.vmware.com/products/converter/
[20:33:34] <frallzor> dont think so, will probably just do the same shitty thing as the rest
[20:33:42] <frallzor> bloody linework that is no good
[20:34:21] <davidf> hi
[20:34:34] <Jymmm> frallzor: Gawd youre a pita, post the PS to filebin.ca
[20:34:52] <Jymmm> or codepad.org
[20:36:30] <frallzor> well blow me, I got it working with the AI-file
[20:36:51] <frallzor> had to do something you never do with those files but it worked =P
[20:36:54] <frallzor> nice outlines now
[20:38:04] <davidf> I'm trying to use a 2nd parport card set for ipins 2-9 as input.
[20:38:55] <davidf> EMC complains onstartup that parport.1.pin-2-in does not exist
[20:39:50] <davidf> etc. ... but if I take the offending lines out of the HAL file, I can start emc and the hal meter shows pin 2 is a funtioning input. What gives?
[20:39:52] <alex_joni> it's 02 not 2
[20:40:04] <davidf> LOL geeeeez.
[20:40:11] <frallzor> wey it works now :)
[20:40:17] <davidf> Thanks alex_joni
[20:41:13] <davidf> bbl
[20:45:59] <alex_joni> np
[20:49:09] <Jymmm> alex_joni: Well, wth man... what if someone had 300 paraport cards, then what?! huh huh huh
[21:01:03] <SWPadnos_> it would still be parport.299.pin-02-in
[21:02:07] <davidf> The missing 0 was the only problem. Thanks!
[21:04:20] <davidf> Man I've been using my mini-mill w/o home switches for a long time. It is awesome to be able to start up, home, mount a part and go. Mo more edge finder every time I set up.
[21:37:49] <alex_joni> Jymmm: the limit is at 8 afaik
[21:37:59] <alex_joni> so it's parport.7.pin-02-in
[21:38:08] <Jymmm> alex_joni: Those Bastards!
[21:38:56] <alex_joni> take it up with Linus
[21:39:18] <Jymmm> alex_joni: That Bastard!
[21:39:23] <alex_joni> but I think it's more of a historical issue (available IO addresses)
[21:40:03] <Jymmm> alex_joni: Probably, as they do it the old skool way
[21:40:26] <alex_joni> Those Bastards!
[21:40:41] <Jymmm> alex_joni: Yeah! I wish I had said that!
[21:41:03] <alex_joni> yeah, wish you did
[21:42:07] <Jymmm> alex_joni: Can you think of a way to run the tubing in the laser without using energy chain?
[21:42:26] <alex_joni> well, there's an idea I've seen on plasmas
[21:42:35] <alex_joni> either energy chain, or a suspender above
[21:42:50] <Jymmm> like a tool balancer?
[21:42:54] <alex_joni> yeah
[21:43:17] <alex_joni> the stuff I've seen is bigger, but it resembles a fishing rod
[21:43:24] <alex_joni> with the hose attached
[21:43:40] <alex_joni> the rod pointing 45 deg. up (from one of the corners of the table)
[21:43:48] <Jymmm> alex_joni: Yeah, that's a lil too tacky for this. I'd do that in a pinch I guess.
[21:44:53] <Jymmm> I wonder how much Igus is gonna screw me on this one =)
[21:45:35] <alex_joni> should be fairly small Igus
[21:45:46] <alex_joni> and there are cheaper alternatives
[21:45:52] <Jymmm> Yeah, they have micro chain now
[21:46:01] <Jymmm> alex_joni: there are?
[21:46:01] <alex_joni> btw, Igus has some 2d and 3d energy chain
[21:46:08] <alex_joni> yes
[21:46:22] <Jymmm> alex_joni: share the wealth young man =)

[22:19:55] <Jymmm> alex_joni: ......SNIP.......
[22:24:26] <Jymmm> alex_joni: Ha! I wonder how much they're selling the fishing rod for?
[22:52:43] <foxtrot_mill> well i think i finally figured out homeing and touching off
[22:53:12] <foxtrot_mill> i just need to figure out a medium better than packing foam sheets
[22:53:56] <foxtrot_mill> my spindle is barely attached and will come off if more than a tinsy bit of upwards pressure is applied to it
[22:54:57] <foxtrot_mill> is there a way to return home automatically without manually jogging it
[22:55:30] <foxtrot_mill> and what is estop, just a SPDT switch to GND on that pin?
[22:58:51] <foxtrot_mill> and whats the program of choice if i wanted to do like a simple engraving like 'EMC2 AXIS' style .1" depth
