[00:06:58] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[00:20:42] <skunkworks> is this this thing on?
[00:25:21] <JymmmmEMC> No, turn it over and try again
[00:31:08] <JymmmmEMC> I need a word here... you buy something theres a problem with the order, and the seller works with you and does the right thing, no hassels, no drama, how do you describe the seller in a very positive fashion?
[00:35:12] <skunkworks> good seller - would do business agian ;)
[00:35:47] <JymmmmEMC> skunkworks: Nah, this seller was above and beyond the norm here.
[00:36:21] <skunkworks> seller went above and beyond to make me happy..
[00:37:03] <JymmmmEMC> I bought a lot of OEM750's. He mistakenly didn't realize not all of them were 750's but mixed 750 and 650s (easy mistake). Admited the mistake, and offered to do whatever to make me happy. and did.
[00:38:04] <skunkworks> that is very nice. That is hard to find
[00:38:48] <JymmmmEMC> I couldn't find a better in-perosn much less online merchant, that's for sure.
[00:39:13] <JymmmmEMC> He sent me one other 750 he had, plus a partial refund.
[00:39:49] <David36_LA> hi all. One question. Is there a know problem with EMC hanging a system if started and shutdown multiple times without rebooting the computer
[00:39:58] <JymmmmEMC> I even asked him if he wanted me to mention there was a problem, and he didn't care either way, said that !!!+++ was good enough. I didn't think so.
[00:40:07] <David36_LA> I use scripts/emc to start it
[00:40:11] <cradek> David36_LA: not that I've heard of. What version of emc are you using?
[00:40:13] <JymmmmEMC> FSCK
[00:40:30] <David36_LA> after about 3-4 times, the next time I try starting it it hangs the computer
[00:40:49] <JymmmmEMC> David36_LA: Well, DONT DO THAT! =)
[00:40:50] <David36_LA> the latest I downloaded a month ago
[00:40:52] <David36_LA> let me check the version
[00:41:26] <JymmmmEMC> skunkworks: Yeah, exceptional sellers are rare, I have never liked the generic fb ppl give.
[00:41:48] <skunkworks> * skunkworks is a generic feedback giver
[00:41:52] <David36_LA> Linux is known to be very stable and I don't see a reason it should hapeen unless there is a memory corruption somewhere in RT or EMC
[00:42:23] <cradek> David36_LA: if it only happens to you, it's probably a hardware problem. we need more details to tell for sure.
[00:42:47] <David36_LA> ok, I understand. I just wanted to know if doing this is a known no-no
[00:42:50] <cradek> I leave the machine running my lathe on for months at a time
[00:43:15] <cradek> nope, not at all
[00:43:24] <skunkworks> I have been running head - playing around with hal files and my computer has been on for a few days now. starting/restarting emc
[00:43:59] <David36_LA> ok
[00:43:59] <David36_LA> thanks
[00:44:14] <cradek> when it hangs does the mouse move, or the capslock light on the keyboard work, or any other sign of life?
[00:44:17] <David36_LA> I use tkemc and stepper_inch
[00:44:36] <David36_LA> everything is dead including the mouse and all keyboard functions
[00:44:53] <cradek> at what step does this happen - is the tkemc window up yet?
[00:45:10] <David36_LA> sometimes, I was able to catch a "segmentation fault" error message when the emc scripts exists
[00:45:24] <David36_LA> on the next emc script run it hangs
[00:45:48] <cradek> have you run memtest86 extensively?
[00:46:23] <David36_LA> the hang happens after the menu to choose the stepper_inch config and it seems just before tkemc comes up. The tkemc screen never shows
[00:46:42] <cradek> ok
[00:46:54] <David36_LA> will try memtest86
[00:46:55] <David36_LA> never tried it
[00:47:11] <cradek> it's on the grub boot menu, hit escape when prompted, and pick it from the menu
[00:47:19] <David36_LA> ok thanks
[00:47:22] <cradek> you should run it for some time (several passes) or overnight
[00:47:31] <David36_LA> good to know
[00:48:20] <David36_LA> starting it right now
[00:48:24] <cradek> is this a new install and it has always happened, or is it new behavior?
[00:49:34] <David36_LA> the motherboard is new and it is a new install
[00:49:51] <David36_LA> but I only noticed this after stop-start cycles
[00:49:55] <cradek> ok so this is not 'old trusted' hardware yet
[00:50:02] <David36_LA> It runs fince otherwise
[00:50:15] <cradek> yeah that's an interesting symptom, can't explain it yet
[00:50:26] <David36_LA> well I can run EMC gcode all night long without a glitch
[00:50:47] <cradek> do you ever get any unusual errors, like the "unexpected realtime delay" error?
[00:50:52] <David36_LA> should memtest86 be at the grub prompt?
[00:50:56] <David36_LA> can't find it
[00:51:15] <cradek> yes it's the last entry in the menu
[00:51:15] <David36_LA> no, real time is fine
[00:51:21] <David36_LA> tested that extensively
[00:51:56] <skunkworks> I thought the memtest was only on the live cd - did you not use the live cd to install emc?
[00:52:01] <skunkworks> emc livecd
[00:52:05] <David36_LA> so memetest86 is not part of grub itself but another bootable file in the menu?
[00:52:14] <cradek> memtest is on every ubuntu CD
[00:52:34] <David36_LA> no, I compiled from latest tar bundle
[00:52:41] <skunkworks> cradek: ah - thought it was something you added for some reason.
[00:52:47] <cradek> oh!
[00:52:59] <cradek> you are not using ubuntu, and not using the released binaries?
[00:53:01] <David36_LA> no
[00:53:20] <cradek> ok then it's not such a sure thing.
[00:53:27] <David36_LA> using vanilla Kernel with RT patches
[00:53:29] <cradek> did you build your own realtime kernel?
[00:53:34] <David36_LA> yes
[00:53:36] <cradek> what version of kernel?
[00:54:00] <David36_LA> 2.6.17 I beleive, old on
[00:54:27] <David36_LA> hol don
[00:54:28] <David36_LA> hold on
[00:54:34] <David36_LA> sorry
[00:54:37] <cradek> you could easily have a software problem then. I was assuming a lot about your setup that was not true.
[00:55:07] <David36_LA> I have been doing this for a year (building from scratch) without problems
[00:55:30] <cradek> that version of the kernel?
[00:55:55] <cradek> I think 2.6.17 worked but .18 is not supported by rtai and .19 is broken BUT don't trust my memory on that
[00:56:00] <David36_LA> 2.6.17 yes
[00:56:08] <David36_LA> I know
[00:56:12] <David36_LA> that is why I use 2.6.17
[00:56:27] <cradek> getting a working rtai setup is sometimes a real crap shoot
[00:56:47] <cradek> do you have the emc2 live cd? if so, boot it and start emc2 a bunch of times on your machine
[00:57:09] <David36_LA> Ok, I am trying to build a minimal system for a product. I need to build from scratch. Is there a kernel/rtai version I should stick to?
[00:57:12] <cradek> we *know* that's a good rtai setup
[00:57:35] <David36_LA> I see
[00:57:43] <David36_LA> a crap shoot like you said
[00:57:49] <cradek> yeah
[00:58:02] <cradek> most of our users are using 2.6.15 with rtai-3.2 I think
[00:58:14] <cradek> you could start with those config files.
[00:58:29] <cradek> your system doesn't have more than 1GB of ram does it?
[00:58:29] <David36_LA> ok
[00:58:55] <cradek> or is your kernel built with any of the bigmem options? those are broken with rtai
[00:59:14] <David36_LA> system as 1GB
[00:59:25] <David36_LA> bigmem. not sure, will check
[00:59:30] <David36_LA> has
[01:00:02] <cradek> boot with mem=768M or whatever the kernel option is and retry
[01:00:22] <cradek> here be demons :-/
[01:00:24] <David36_LA> So you guys get this kind of unstability everytime you switch kernel or RTAI?
[01:00:47] <cradek> I don't know how to say it except it takes a while for us to trust a new kernel.
[01:00:53] <David36_LA> ok
[01:00:59] <cradek> it's pretty hard to build one that will run on everyone's machine
[01:01:04] <cradek> it has taken a lot of experimentation
[01:01:06] <David36_LA> I should stick to what you use then
[01:01:26] <cradek> I recommend you at least start with our .config etc
[01:02:07] <cradek> you probably have too many unknowns right now to troubleshoot effectively
[01:02:14] <David36_LA> ok, have lots of things to try, will get back to work
[01:02:18] <David36_LA> thanks all
[01:02:23] <cradek> good luck, come back and let us know how it goes
[01:03:51] <twice2> cradek: are you familiar with a sound app, called jacks for alsa
[01:04:05] <cradek> sorry no
[01:04:16] <David36_LA> I am
[01:04:46] <David36_LA> a bit familiar with Jacks
[01:05:04] <twice2> been a while but iirc it's needs low latency
[01:05:17] <David36_LA> yes
[01:05:24] <twice2> and i belive i had it running smp
[01:05:28] <David36_LA> it uses a low latency kernel preferably
[01:05:33] <David36_LA> depends what you want to do
[01:07:15] <twice2> oh, btw, i've read the entire users manual. i found one typo on page 48. "you system" should be "your system" :)
[01:07:38] <cradek> twice2: only one? that's amazing
[01:08:11] <twice2> yep, kudoz to thoze you wrote it
[01:08:42] <twice2> dinner time
[01:10:37] <kanzur1> kanzur1 is now known as kanzure
[01:55:14] <David36_LA> anyone know the root passwd when booting from emc live cd?
[01:55:29] <ds2> isn't it standard ubuntu?
[01:55:43] <ds2> aka no usable root password; use sudo?
[01:56:51] <David36_LA> trying to run latency tests but it gives error opening /dev/rtf3
[01:57:18] <ds2> so become root and rerun it
[01:57:21] <ds2> i.e. "sudo su -"
[01:57:40] <David36_LA> ah ok, just what I needed
[01:57:44] <David36_LA> thanks
[01:58:14] <ds2> it is an ubuntu-ism
[01:58:26] <ds2> they believe having a root password is insecure
[01:58:46] <David36_LA> same error
[01:59:11] <jmkasunich> what is the actual error message?
[01:59:19] <David36_LA> not sure what /dev/rtf3 is but it isn't there
[01:59:19] <jmkasunich> and what command is it in response to?
[01:59:26] <jmkasunich> you need to create it
[01:59:40] <jmkasunich> our wiki instructions for running the latency test tell you to do that
[01:59:40] <David36_LA> run command in kern/latency

[02:00:53] <a-l-p-h-a_> boo!
[02:01:10] <a-l-p-h-a_> jmkasunich, how's the mesa?
[02:01:26] <jmkasunich> slow
[02:01:32] <David36_LA> thanks jmkasunich
[02:01:39] <jmkasunich> you're welcome
[02:01:43] <a-l-p-h-a_> stopped, or slow?
[02:01:47] <jmkasunich> slow
[02:01:53] <ds2> Oh the board...
[02:01:56] <a-l-p-h-a_> reverse time travel slow? :)
[02:02:01] <jmkasunich> I've been having mental blocks, but I've started making some progress lately
[02:02:05] <ds2> thought alpha was asking about the state of a hill ;)
[02:02:24] <a-l-p-h-a_> there's a hill named Mesa?
[02:02:34] <ds2> a flat topped hill is a mesa
[02:02:34] <jmkasunich> a mesa is a hill
[02:02:39] <jmkasunich> flat-topped one
[02:02:48] <ds2> worked with people in AZ today so....
[02:02:48] <a-l-p-h-a_> I just wikied it.

[02:10:42] <dmwaters> {global notice} Good day folks, we have some maintenence about to happen to 2 rotation servers. These boxes have been out of rotation for a while but we'll still lose some users.
[02:14:56] <skunkworks> jmkasunich: did you see - I finally ran dc into the big servos - 150v is 1200rpm on the dot. (max rating of those servos) Not too scary ;)
[02:16:58] <jmkasunich> cool
[02:17:41] <skunkworks> and I mean - right on the dot - voltmeter read 150.0v and the rpm meter read 1200rpm.
[02:17:43] <cradek> I'm glad alex found this devilspie thing so we don't have to crap up AXIS with window management junk
[02:38:50] <skunkworks> wow - they are having problems... since when did irc broadcasts show up as PM's?
[02:39:05] <jmkasunich> damn... somebody is after "my" mill
[02:39:14] <skunkworks> uh oh
[02:39:19] <jmkasunich> http://cgi.ebay.com/Proteo-CNC-Vertical-Mill_W0QQitemZ320120898091QQcmdZViewItem
[02:41:16] <skunkworks> 5 axis? how is that layed out?
[02:41:27] <skunkworks> hard to make out
[02:41:43] <jmkasunich> http://www.barer.com/proteo5.html
[02:41:45] <jmkasunich> scroll down
[02:42:14] <skunkworks> oh - cool
[02:42:36] <skunkworks> that is the 4 and 5 axis setup that I would like to make.
[02:42:49] <skunkworks> to add to an existing 3
[02:43:19] <cradek> that would be really neat
[02:43:25] <jmkasunich> I've been watching that thing at HGR for a month or so now
[02:43:35] <skunkworks> easier than trying to do a tilt/swivel spindle
[02:43:44] <jmkasunich> theres no way I'd pay more than 1K tho
[02:44:09] <jmkasunich> the bastards had to go and put it on ebay
[02:44:11] <cradek> 'scale feedback for .00008" repeatability'
[02:44:42] <jmkasunich> it has linear scales
[02:45:56] <jmkasunich> can you say "photoshop"?
http://i14.ebayimg.com/05/i/07/96/f9/9f_1_b.JPG
[02:46:05] <jmkasunich> thats the pic on HGRs Ebay store
[02:46:19] <jmkasunich> the entire parking lot is fake
[02:46:29] <cradek> wtf
[02:46:42] <cradek> isn't it really gravel?
[02:46:57] <jmkasunich> its actually very ratty and beat up. mixed gravel and broken asphalt
[02:46:59] <cradek> (only been there once)
[02:47:10] <cradek> strange - wonder why they did that
[02:47:19] <jmkasunich> no clue
[02:49:04] <skunkworks> jmkasunich: How is the excavating shaping up? tons of bids?
[02:49:10] <jmkasunich> none yet
[02:49:21] <jmkasunich> the original guy hasn't gotten back to me yet
[02:49:32] <jmkasunich> and I've haven't gone looking for others yet
[02:49:39] <skunkworks> I may have a building permit for a garage tomorrow..
[02:49:42] <jmkasunich> I think I'm in denial
[02:49:45] <skunkworks> ;)
[02:50:36] <skunkworks> 48X26
[02:50:43] <jmkasunich> nice
[02:50:48] <jmkasunich> wide or deep?
[02:50:59] <skunkworks> 26 deep - 48 wide
[02:51:03] <skunkworks> 3 car +
[02:51:03] <jmkasunich> 4 cars?
[02:51:06] <jmkasunich> ah
[02:51:10] <skunkworks> 3 doors
[02:51:17] <skunkworks> with tinker area
[02:51:32] <jmkasunich> I wish I had made our garage deeper
[02:51:52] <jmkasunich> I could have fit 48x22 instead of 28x22
[02:51:57] <jmkasunich> wall off the back half....
[02:52:12] <jmkasunich> damn city probably wouldn't allow it tho
[02:52:23] <skunkworks> odd restrictions like - cannot be more than 30% of the back yard.
[02:52:41] <skunkworks> cannot have more square footage as the house
[02:52:45] <skunkworks> than the house
[02:52:48] <jmkasunich> yeah, stuff like that
[02:53:30] <jmkasunich> "pursuit of happiness" my ass
[02:53:45] <jmkasunich> "sorry, you can't paint your house that color"
[02:57:19] <skunkworks> don't have that problem here yet.. village of 1300
[02:57:30] <jmkasunich> I really would be happier living in a more rural area ;-)
[02:57:53] <jmkasunich> only problem is that as you go more rural prices go up
[02:57:56] <jmkasunich> a lot
[02:58:10] <jmkasunich> until you get 20 or more miles east
[02:58:10] <cradek> if you go more rural still, they go back down
[02:58:25] <jmkasunich> right, but thats a long commute, and its in the snow belt
[02:58:46] <skunkworks> I live right down town ;)
[02:58:48] <cradek> yay lincoln
[02:59:06] <jmkasunich> :P
[03:00:07] <skunkworks> catfish days this weekend.. They are already setting up the rides. 3 blocks from the house.. Very interesting (first time living in town)
[03:00:35] <jmkasunich> I like my less than 2 mile commute, so I guess I can live with being a surburbanite
[03:01:02] <skunkworks> now if I could find a job in this town.... I have a 20 minute drive.
[03:01:17] <skunkworks> not bad - all strait nice roads
[03:01:26] <jmkasunich> its annoying that the good jobs are never where we want to live
[03:01:40] <skunkworks> wife otoh drives 1 hour
[03:01:43] <jmkasunich> ouch
[03:01:56] <jmkasunich> our roads are fairly straight, but there's too many people on them
[03:02:10] <skunkworks> yah - she works for the tech collage - hoping to get a job closer soon
[03:02:18] <jmkasunich> cradek: whats the population of Lincoln?
[03:02:36] <cradek> 250k I think
[03:02:52] <jmkasunich> thats about half of Cleveland proper
[03:03:11] <jmkasunich> but there are lots of burbs, the area is something like 1.5 million
[03:03:12] <cradek> it has some features of bigger cities (because it's a college town)
[03:03:27] <skunkworks> time for bed again.. you guys are doing a great job.
[03:03:33] <skunkworks> thank you.
[03:03:44] <cradek> thanks skunkworks, goodnight

[04:25:23] <Jymmm> Hey, if you could have anything from McMaster, what would it be?
[04:26:20] <ds2> a copy of their paper catalog!
[04:27:11] <ds2> the amount of redundancy between the different projects out there is incredible
[07:52:35] <cncjunior> hello !
[08:08:01] <sebjames> Back on with homing in MDI/Auto mode...
[08:14:14] <sebjames> jdi.py is a short and simple program. It starts the machine, loads and runs a program and stops the machine. What I will need to do with it is to just load and run a program, without starting or stopping the machien - I'll need to split those out into separate files.
[08:15:03] <sebjames> That's because when emc stops, the "real" machine is shut down, and then requires an operator to press the "on" button on the real machine after emc has started to bring it back into operation
[08:15:20] <sebjames> This ensures that the machine can't be switched on without the CNC running
[08:30:50] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[08:58:00] <sebjames> Ok, I'm looking for the hal signal that's used as the probe when you call a G38.2 command. Can anyone help with that?
[08:59:05] <sebjames> Nevermind - I googled for it :)
[09:00:56] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[09:22:48] <sebjames> Well, that worked. I do the G38.2 move, and if I previously called (PROBEOPEN somfile.txt) the offset goes into that file.
[09:23:29] <sebjames> What I'd really like to do is offset the X axis by the location at which the probe triggered, without worrying about placing the data in a file.
[09:24:29] <sebjames> Ah - it seems you _need_ to open the file for the data to be available in parameter 5061.
[09:31:06] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[09:48:53] <sebjames> I'm getting the error "Bad character used" when I try this: G0X#5061-8
[09:52:50] <sebjames> Hi Martin, I'm trying G0X#5061-8 and am getting the error "Bad character used" (NCE_BAD_CHARACTER_USED). You're supposed to be able to add an offset to the value stored in a parameter, right?
[09:54:24] <Martin_Lundstrom> sebjames: I dont know
[09:55:01] <sebjames> It says you can in the language overview in the User Manual
[10:01:46] <sebjames> Ah, you have to do: G0X[#5061-8]
[10:02:03] <Martin_Lundstrom> ok
[10:14:48] <sebjames> I'd like to re-set my X encoder before each run. I can do this by setting a hal signal into my 5i20 i/o board, but it generates a joint following error. Any way round this?
[10:14:51] <sebjames> Is there a proper way to reset the X encoder?
[10:19:16] <sebjames> Actually, I don't need to. I would have to process 3600 bars of steel before I overflowed the encoder counter
[10:19:51] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[10:21:26] <sebjames> Is there a parameter which holds the "current position of the joint"
[10:21:52] <sebjames> That is, can you program a move which is "100 mm from where I am now"
[10:47:37] <Martin_Lundstrom> Have a look at the HAL components, what they get as feed etc, you will find useful stuff
[11:01:52] <sebjames> Thanks Martin
[11:07:15] <sebjames> I just churned out 3 plates, with no X zeroing required!
[11:07:20] <sebjames> Nice
[11:09:37] <archivist> mass production!
[11:25:15] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[11:46:15] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[12:28:50] <maddash> somehow,
[12:29:42] <maddash> "ci->wp0 = wayPoint(ci->x0, ci->x1, ci->x2);" ... "ci->coeff = cubicCoeff(ci->wp0, ci->velp0, ci->wp1,"
[12:30:25] <maddash> given the above definitions of wp0, wouldn't cubicInterpolate return the wrong position at time 0?
[12:35:23] <maddash> because wp0 != x0, yet cubicCoeff is called to return coefficients such that "x(0)" (see definition of cubicCoeff) equals wp0.
[12:36:08] <The_Ball> what is this used for?
[12:36:40] <maddash> cf. src/emc/kinematics/* and src/emc/motion/*
[12:36:54] <maddash> cradek, jepler: ^^
[12:38:23] <maddash> The_Ball: ^^
[12:40:30] <The_Ball> im not saying anything because i have nothing clever to add
[12:42:29] <skunkworks_> The_Ball: how is the mill working?
[12:42:54] <The_Ball> it's working well, but i have not been working it ;)
[12:42:58] <The_Ball> to much going on at the moment
[12:44:08] <The_Ball> but i'll get back to the project, at the moment im trying to research how to design things simply and quickly
[13:09:42] <skunkworks_> rayh: hey :)
[13:12:27] <rayh> Hi skunkworks
[13:14:42] <CIA-8> 03jepler 07TRUNK * 10emc2/src/hal/utils/ (scope.c scope_horiz.c scope_trig.c scope_usr.h scope_vert.c): automatically restart scope after most changes that stopped it before(e.g., moving trigger time, turning channel on/off)
[13:21:02] <skunkworks_> rayh: how is the wireless coming?
[13:21:50] <rayh> I got a linksys card for my laptop. It works at at least a couple of places I go.
[13:22:16] <skunkworks_> aww - I was wondering about your home internet
[13:22:19] <rayh> The microwave link for home is supposed to be tested next week sometime.
[13:22:31] <skunkworks_> ooh - nice
[13:23:58] <maddash> microwave + wifi?
[13:24:22] <rayh> I'll hang an access point on my end of the link.
[13:24:30] <alex_joni> hi rayh
[13:24:34] <rayh> Hi alex.
[13:24:52] <alex_joni> greets from athens
[13:24:58] <maddash> alex_joni: did you know that the range of motion of your "three-axis" is a triangle?
[13:25:08] <alex_joni> range of motion?
[13:25:32] <alex_joni> it obviously needs to stay between the 3 points
[13:25:34] <rayh> lucky guy
[13:25:44] <alex_joni> rayh: work though, I'll be back tomorrow
[13:25:49] <maddash> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Alex_Joni's_Toy
[13:26:02] <alex_joni> maddash: the whole thing is about 40-50 cm wide
[13:26:12] <maddash> alex_joni: what's the point of it?
[13:26:19] <alex_joni> to prove kinematics
[13:27:39] <alex_joni> and... it's a toy
[13:27:42] <alex_joni> to play with :P
[13:32:54] <sebjames> Hi alex_joni.
[13:32:57] <alex_joni> hi
[13:33:05] <awallin> alex_joni: do you know if anyone's made a hexapod using the same idea?
[13:33:08] <sebjames> I've made some plates, got X probing to work (instead of homing)
[13:33:16] <alex_joni> awallin: NIST had one working
[13:33:26] <alex_joni> sebjames: great
[13:33:51] <alex_joni> awallin: google for robocrane
[13:34:10] <sebjames> So all I need to do now is modify jdi.py to run continuously - without switching machine off/unloading emc between jobs and also to throw up my custom operator panel
[13:34:29] <alex_joni> sounds like a piece of cake :(
[13:34:29] <alex_joni> :)
[13:34:44] <sebjames> I want jdi.py to automatically read programs in when flagged to, and then execute them.
[13:34:56] <awallin> sebjames: this is the saw thing you had pictures of??
[13:35:02] <sebjames> awallin: Yeah
[13:35:11] <sebjames> awallin: The smaller one
[13:35:53] <awallin> how did you do your control panel?
[13:37:14] <rayh> Hi awallin NIST has built a number of cable hexapods.
[13:37:24] <sebjames> awallin: pyvcp
[13:37:48] <awallin> rayh: are any of them stiff enough for anything but demo purposes?
[13:37:53] <rayh> I'm not at home so don't have access to links.
[13:37:59] <sebjames> Is there any documentation for the python emc component?
[13:38:11] <awallin> sebjames: cool, you might be the first person using only pyvcp for controlling a machine
[13:38:22] <rayh> There is one in the states that sprays LARGE aircraft.
[13:38:35] <awallin> sebjames: pydoc emc will give you something. jepler is a good source for the rest :)
[13:38:50] <rayh> Another that can travel around about 1/3 of an aircraft carrier.
[13:39:36] <sebjames> awallin: Excellent. You see, we don't want our operators to have anything available that they might mess up ;)
[13:42:17] <awallin> but pyvcp can only manipulate HAL pins. even with halui you will need some more code for autoloading of new g-code files
[13:43:11] <alex_joni> awallin: the stuff NIST built is very stiff
[13:43:29] <alex_joni> they had the robocrane which is a platform with a robot mounted underneath it
[13:43:33] <sebjames> awallin: Yes, I figured that
[13:43:38] <rayh> http://rds.yahoo.com/_ylt=A0geu8K7L5ZGD78AaVpXNyoA;_ylu=X3oDMTE5cnBoMTZjBHNlYwNzcgRwb3MDMQRjb2xvA2FjMgR2dGlkA0Y4NjFfMTQyBGwDV1Mx/SIG=12mp8fovm/EXP=1184334139/**http%3a//www.isd.mel.nist.gov/projects/robocrane/papers/Reconfig.pdf
[13:43:49] <sebjames> awallin: That I need to add to jdi.py
[13:45:21] <sebjames> Is jepler here??
[13:46:25] <awallin> rayh: thanks for the link! might be a fun project if I sometime have six extra stepper motors/drives and some free time
[13:46:43] <awallin> sebjames: do you already have jdi.py and a pyvcp panel working together?
[13:47:09] <rayh> You bet. I had a great time running the small one from NIST.
[13:56:14] <The_Ball> any idea why that very solid hexapod have the actuators mounted horizontaly on the spindle plate an verticaly on the frame?
[13:59:05] <cradek> I could recognize CDS anywhere...
[14:03:25] <alex_joni> CDS?
[14:04:31] <cradek> the cds ngc program - there's a picture of the part in that pdf
[14:05:00] <alex_joni> ahh
[14:06:03] <sebjames> awallin: NO, not yet. Just finding my way around
[14:06:48] <cradek> you do understand that jdi can just as easily home an axis as run a program, right?
[14:07:10] <cradek> it can do anything a normal gui can do
[14:07:43] <sebjames> awallin: Just seen that you seem to need emc running in a tkemc/mini/whatever window before running jdi. Have already tweaked it so it waits for the operator to press the FDB600 "ON" button then the FDB600 clear error/enable button
[14:07:53] <sebjames> cradek: I see that now
[14:08:07] <sebjames> cradek: Because it can be used to switch modes!
[14:08:14] <cradek> sure
[14:08:24] <cradek> you can have the emc startup script run jdi as the only "gui" if you want that
[14:09:43] <sebjames> cradek: I think I see that. Just a question of running halui, milltask and io first, right?
[14:09:54] <sebjames> Oh - emc startup will do that.
[14:10:00] <alex_joni> sebjames: right
[14:10:00] <cradek> yeah
[14:10:04] <cradek> set DISPLAY=jdi in the inifile
[14:10:15] <sebjames> Ok. *nod*. jdi, rather than jdi.py?
[14:10:16] <alex_joni> and place jdi in the bin/ dir
[14:10:19] <cradek> you can run any 'gui' as the 'display'
[14:10:34] <sebjames> Ok. I'm looking forward to playing with this tomorrow.
[14:10:37] <alex_joni> sebjames: make it executable, and rename it to jdi
[14:10:48] <sebjames> alex_joni: Rightho
[14:11:15] <sebjames> Bye all.
[14:11:41] <alex_joni> bye
[14:12:03] <cradek> so many approaches
[14:12:32] <alex_joni> had a user ask about bdi-emc and changing pin numbers
[14:13:10] <cradek> ouch
[14:13:30] <alex_joni> actually he wanted to add cooland and spindle, etc
[14:13:32] <cradek> I think you could change the IO pins but not the step/dir pins
[14:13:47] <cradek> it's been a while :-)
[14:14:37] <alex_joni> yeah
[14:15:04] <rayh> BDI had about the same set of movable "pins" as iocontrol.
[14:15:41] <rayh> except the tool
[14:16:33] <alex_joni> rayh: you mean as emc1 milltaskio?
[14:16:39] <alex_joni> or bridgeportio ?
[14:16:51] <alex_joni> * alex_joni forgets which one exactly had the second parport
[14:18:33] <rayh> bridgeport task
[14:19:04] <alex_joni> yeah that..
[14:19:11] <alex_joni> it's been a while ;)
[14:22:37] <skunkworks_> you can't tell him - 'we don't support emc1 anymore - please upgrade' ;)
[14:22:53] <skunkworks_> 'please purchase an upgrade' ;)
[14:22:58] <alex_joni> haha
[14:23:06] <alex_joni> your paid support has expired
[14:23:12] <skunkworks_> he he
[14:23:14] <alex_joni> please subscribe to another plan
[14:23:15] <cradek> you could offer 20% off his upgrade price
[14:23:43] <alex_joni> too bad you guys are so far away
[14:23:52] <alex_joni> I'd have something to celebrate next week
[14:24:36] <cradek> what's that
[14:24:58] <alex_joni> 3 years around emc
[14:25:12] <alex_joni> * alex_joni is reading some IRC logs from 2004
[14:25:18] <skunkworks_> wow - you know your exact date? ah
[14:25:18] <cradek> wow
[14:25:20] <alex_joni> I was quite clueless :P
[14:25:29] <cradek> haha
[14:25:54] <alex_joni> skunkworks_: 2004.07.18 is the oldest ref I found
[14:26:33] <skunkworks_> I remember being scared of jmkasunich
[14:26:50] <alex_joni> ahhahahaa
[14:26:53] <cradek> you mean you're not still?
[14:27:01] <skunkworks_> Na
[14:27:09] <alex_joni> wonder who can guess what my first question was?
[14:29:15] <rayh> I wasn't real quick to jump on IRC.
[14:30:17] <skunkworks_> the history on linuxcnc.org only goes back to 10-18-2004
[14:30:19] <rayh> Is it possible to build a non-realtime sim only EMC?
[14:30:35] <cradek> yes
[14:30:43] <alex_joni> skunkworks_: :P
[14:30:48] <alex_joni> http://metalworking.net/irclogs/2004/%23emc.freenode.20040718.log
[14:31:08] <skunkworks_> alex_joni: what was your first question? how to burn an iso? ;)
[14:31:22] <alex_joni> skunkworks_: no.. how to use estop with minimill
[14:31:39] <alex_joni> and ray told me how to use bridgeporttask and io and overlap the lpt's
[14:31:52] <rayh> That was a long time ago.
[14:32:00] <alex_joni> (the same discussion as 20 minutes ago :P)
[14:32:07] <alex_joni> rayh: sure feels like it
[14:32:09] <rayh> same answer.
[14:32:15] <skunkworks_> I actually thought that int he back of my mind.
[14:32:19] <alex_joni> I wonder how it feels for you after all that time..
[14:32:27] <rayh> my favorite radio commercial was
[14:32:32] <alex_joni> since you started with EMC I mean
[14:32:45] <cradek> [12:33] <alex_joni> hello there, anyone here?
[14:32:48] <cradek> ^^ alex's first question
[14:32:49] <alex_joni> ooh.. bush is providing an update
[14:32:54] <rayh> "I've been drinking Rainier Ale for as long as I can rmember --
[14:32:54] <alex_joni> cradek: :P
[14:32:56] <skunkworks_> haha
[14:32:59] <rayh> which is about three days.
[14:33:03] <cradek> that's so irritating :-)
[14:33:15] <skunkworks_> irc newb
[14:33:54] <cradek> wonder when I first showed up
[14:34:37] <archivist> * archivist is very noob in here
[14:34:43] <cradek> at first I wanted phase drive, but it didn't work right, so I had to change the source and recompile, which was a pain
[14:35:29] <alex_joni> cradek: tell me about it
[14:35:40] <alex_joni> I think I compiled for 3 weeks before I started emc the first time
[14:36:44] <skunkworks_> I looked at the bdi and about a year before I really got into emc again.. It is what caused me to run turbocnc for a while.. :)
[14:36:56] <cradek> jeff and I finally made a step-dir to phasedrive converter for my mill
[14:37:23] <jepler> cradek: that wasn't just because of the difficulties doing phase drive in emc1 -- it was to get 4 axes on one port
[14:37:30] <jepler> at least, that's my recollection
[14:37:35] <cradek> ah
[14:37:41] <cradek> bet you're right
[14:37:54] <cradek> then I tried to use backlash compensation...
[14:37:55] <alex_joni> I started by building a kernel for SuSE
[14:37:55] <cradek> * cradek shivers
[14:38:02] <alex_joni> on my 300MHz SBC
[14:38:14] <alex_joni> a RT kernel I mean
[14:38:32] <alex_joni> rtai 24.1.11 ? or something like that
[14:38:44] <cradek> I used rtlinux-3
[14:39:21] <alex_joni> [14:12] * cradek has quit IRC (niven.freenode.net irc.freenode.net)
[14:39:29] <alex_joni> 2004.05.23
[14:40:09] <alex_joni> [10:06] <cradek> freqmod with G61 did it perfectly - I will try steppersegmot with G61 too
[14:40:17] <alex_joni> 2004.05.30
[14:40:55] <skunkworks_> <jmkasunich> I don't know how to write GUIs very well :)
[14:41:09] <alex_joni> heh.. he still says that
[14:41:18] <skunkworks_> yes :)
[14:44:23] <cradek> what is G61?
[14:44:32] <alex_joni> beats me..
[14:44:41] <alex_joni> exact stop?
[14:44:44] <jepler> G61 is exact stop
[14:44:47] <cradek> oh duh
[14:45:23] <cradek> the TP was really bad at the time - everything got cut round and wrong - I was trying to do PCBs
[14:45:28] <alex_joni> [09:59] <cradek> hello
[14:45:28] <alex_joni> [09:59] <les> sawyour post about steppersegmot
[14:45:41] <alex_joni> that's the oldest I found in the logs
[14:45:49] <alex_joni> 2004.05.30
[14:46:07] <alex_joni> [10:55] * jepler gets a good laugh from today's dilbert
[14:46:26] <alex_joni> 2004.06.27 oldest from jeff :)
[14:46:30] <skunkworks_> I see nothing has really changed ;)
[14:46:40] <cradek> that can't have been the first time - at first paul helped me compile my fixes and gave me commit access
[14:46:41] <alex_joni> skunkworks_: lol
[14:46:52] <alex_joni> cradek: might be older than the logs I have
[14:47:48] <cradek> Site Member Since: 05/29/2004
[14:47:52] <cradek> ^ sourceforge
[14:48:16] <cradek> so it was right around then - I made the sf account for emc work
[14:49:15] <skunkworks_> so - when is the next election?
[14:49:25] <cradek> about six months ago
[14:49:29] <alex_joni> beats me :)
[14:49:44] <alex_joni> Site Member Since:08/30/2004
[14:51:30] <alex_joni> 2004-05-30 17:56:53 jmkasunich Added user cradek (cradek got devel access)
[14:51:56] <alex_joni> 2004-08-30 18:36:17 jmkasunich Added user alex_joni (same for me :)
[14:57:51] <skunkworks_> ok - that makes sense - I got on irc around nov-dec and you guys where talking about it.
[15:00:39] <alex_joni> [13:27] <alex_joni> btw, now that things are getting redone, how bout reducing portability to some old platforms?
[15:00:42] <alex_joni> [13:27] <alex_joni> i mean 2.0.x kernels
[15:00:44] <alex_joni> * alex_joni smiles :)
[15:03:00] <alex_joni> <alex_joni> compiled on a 2.4.21 with rtai 24.1.12
[15:03:18] <alex_joni> so my memory is only a bit off ;)
[15:13:00] <skunkworks_> logger must have stopped at some point during my first post. The earliest one that I can find is 02:00:51 <skunkworks> just an update - for some reason I thought my ini file period was set to .000016. It wasn't - it was set to .000022. Now I can get 25ipm from z. If I go 1:1 on the drive I should be able to double that.
[15:16:27] <skunkworks_> one of the reasons jmk scared me '<jmkasunich> skunkworks: I just told you, not in standard G-code (which is what emc does)'
[15:16:38] <skunkworks_> ;)
[15:16:45] <alex_joni> [11:37] * skunkworks has joined #emc
[15:16:58] <alex_joni> [11:45] <skunkworks> I wanted to thank everyone for their hard work on emc. I just got it to work on my machine.
[15:16:59] <alex_joni> [11:45] <alex_joni> skunkworks: really? great
[15:17:03] <alex_joni> [11:46] <cradek> what kind of machine?
[15:17:04] <alex_joni> [11:46] <skunkworks> Latest (4.3 bdi) iirc. starting out with steppers - would like to move to servos at some point
[15:17:16] <alex_joni> 2005.11.21
[15:17:56] <skunkworks_> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2005/2005-11-21.txt
[15:18:11] <skunkworks_> missing
[15:18:21] <skunkworks_> I moved to emc2 very quickly
[15:18:46] <alex_joni> http://metalworking.net/irclogs/2005/%23emc.freenode.20051121.log
[15:19:00] <skunkworks_> installing emc2 on the bdi
[15:20:01] <alex_joni> later guys
[15:20:11] <skunkworks_> bye alex
[15:25:18] <Martin_Lundstrom> Dallur: Is the corner lock working as it should?
[15:34:04] <Dallur> Martin: I tested in simulation, but not in real world
[15:34:17] <Dallur> Martin: the sensitivity is critical though
[15:34:19] <Martin_Lundstrom> OK
[15:38:45] <Martin_Lundstrom> Dallur: I have a new version of my z filter, ill test it and then mail it to you
[15:46:40] <Dallur> kk
[15:53:33] <cradek> huh, I was difficult even back in 2005
[16:10:27] <skunkworks_> difficult? I stumbled across some posts from paul_c.. Now that was difficult.
[16:10:56] <archivist> as hard as jymm ones
[16:17:52] <skunkworks_> no - like this
http://www.tuxcnc.org/pivot/entry.php?id=7#body
[16:23:06] <archivist> ah a bit disguntled
[16:24:05] <skunkworks_> yes. He did not like the direction emc was taking.
[16:24:42] <cradek> he still shows up once in a while. (it's usually interesting and entertaining.)
[16:26:07] <archivist> its the nice thing about open source, you can fork off and do your thing, its even better some times
[16:27:46] <cradek> yep
[16:28:04] <archivist> the only dificult thing is open and unjust criticism
[16:29:35] <cradek> nah - badmouthing projects you don't like (and left in a huff) only makes you look bad, not the project
[16:30:29] <archivist> I have seen a club nearly killed by it though
[16:34:51] <archivist> nice thing abiut todays job (2.7mm od pinion) is the waiting time between cuts IRC time!
[16:35:15] <cradek> archivist: did you get some elgin balance staffs yet?
[16:36:23] <archivist> not yet ebay bloke didnt get back to ma afet I gave hime the serial no, there is a chance a local has one
[16:39:11] <skunkworks_> we forgot 'hi paul'
[16:40:01] <cradek> eh, doubt he still watches for his name, it's been years?
[18:33:15] <maddash> awfully quiet in here
[18:33:28] <lerneaen_hydra> yep
[18:33:32] <lerneaen_hydra> party!
[18:33:44] <lerneaen_hydra> nobody's watching!
[18:34:05] <maddash> whoa that was fast
[18:34:12] <skunkworks_> What?
[18:34:36] <maddash> * maddash passes out fpga
[18:34:37] <maddash> s
[18:36:42] <maddash> aheh, i just exhumed an old compaq workstation from the garage, and guess what? It's dual processor!
[18:37:29] <skunkworks_> Sweeet..
http://www.linuxcnc.org/experimental/
[18:38:23] <maddash> whoa -- are those packages for ubuntu or debian?
[18:38:30] <skunkworks_> ubuntu
[18:38:34] <skunkworks_> smp
[18:38:56] <alex_joni> hi guys
[18:38:57] <skunkworks_> I don't know what is what.. when I played with it - there was only 3 files ;)
[18:39:06] <skunkworks_> alex is back ;)
[18:39:15] <maddash> heh, they're source/image/header packages
[18:39:26] <maddash> damn, too bad i'm halfway through my debian etch netinstall
[18:39:28] <cradek> skunkworks_: they all have various problems. cover your eyes and walk slowly backwards
[18:39:37] <skunkworks_> heh ;)
[18:39:52] <maddash> cradek: problems? aren't you running an smp setup yourself?
[18:39:51] <skunkworks_> cradek: whatever I used seem just fine..
[18:40:05] <alex_joni> cradek: tell him that when he's standing at the edge
[18:40:11] <cradek> actually the .20 seems ok but I didn't bother to put in the ubuntu bootsplash hackery
[18:40:25] <cradek> the .17 have an irritating keyboard problem (at least on my computer)
[18:41:24] <alex_joni> cradek: is that still needed? :/
[18:41:41] <cradek> yes, ubuntu needs vesafb to be a module, and it isn't in the base kernel
[18:41:42] <alex_joni> (the usplash stuff..)
[18:42:08] <cradek> I didn't bother to patch that mess into the .20 kernel (since it was just for me)
[18:42:35] <maddash> hm, when you tunnel X11 through ssh, does the entire app run on the host or the client?
[18:43:07] <alex_joni> on the host
[18:43:19] <alex_joni> only the GUI gets forwarded to the client
[18:44:00] <maddash> so there's no way to run emc's gui (or even emcsvr) on another host?
[18:44:36] <alex_joni> sure there is
[18:44:50] <alex_joni> the GUI talks to the rest of emc through NML
[18:44:52] <maddash> the wiki only suggests an ssh tunnel
[18:45:09] <alex_joni> and NML can be across multiple hosts and architectures
[18:45:18] <alex_joni> you can run the GUI on windows for example
[18:45:42] <maddash> besides an ssh tunnel?
[18:46:01] <alex_joni> http://www.linuxcnc.org/handbook/part3/remoteg.html
[18:46:42] <alex_joni> "Another approach actually runs the the second GUI on the remote PC, and sends NML commands over the network. Somebody who knows how to do that is going to have to finish this document...."
[18:47:23] <cradek> that setup works poorly and I suggest you avoid it
[18:48:09] <maddash> alex_joni: the page doesn't contain that
[18:48:18] <maddash> cradek: reason being...?
[18:48:30] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Running_Multiple_User_Interfaces
[18:48:47] <alex_joni> maddash: reason beeing you need mostly the same directory layout for it to make sense
[18:48:54] <alex_joni> when you're loading files & such
[18:48:55] <cradek> if the guis used only nml, it would work fine, but they also use file IO
[18:49:13] <cradek> and, there's no reason to do it, remote X is a better solution
[18:49:25] <alex_joni> cradek: speed might be an issue
[18:49:32] <alex_joni> not for a local network though
[18:50:48] <maddash> actually, speed is an issue, because my video card happens to be some 8MB fossil and the processors are each P3 500MHz
[18:51:12] <alex_joni> * alex_joni was talking about network bandwidth
[18:51:13] <cradek> dual P3 500 is a fine machine
[18:51:41] <cradek> I ran my mill on a dual P2 350
[18:51:42] <jepler> when using remote X it is the video card of the display machine which matters
[18:52:00] <alex_joni> I ran my first emc2 on a 300MHz sbc
[18:52:32] <maddash> we'll see after i finish compiling.
[18:52:42] <skunkworks_> what is sbc?
[18:52:48] <skunkworks_> single board computer?
[18:53:17] <maddash> yep.
[18:53:47] <maddash> 'dallur'? isn't that in emc2/configs?
[18:54:03] <alex_joni> yeah, it was initially
[18:54:13] <alex_joni> then it developed some AI and started talking in here
[18:55:19] <maddash> ah, so that's how a roomba works.
[18:55:32] <alex_joni> yeah, quite similar
[18:55:46] <maddash> hm, i've always wondered how the tp works on those machines
[18:56:46] <alex_joni> if (obstacle in front) { new_direction = current_direction+random(180) } else { go_forward(); }
[18:57:52] <alex_joni> you can see that from this nice movie:
http://hackedgadgets.com/2006/06/28/line-following-roomba/
[18:58:14] <alex_joni> the actual algorith is probably a bit more stupid than what I wrote above
[18:59:39] <maddash> rofl
[18:59:52] <maddash> it looks confused
[19:00:02] <lerneaen_hydra> that algorithm looks really really stupid
[19:00:13] <lerneaen_hydra> like something an 8th grader does with lego
[19:00:23] <alex_joni> lerneaen_hydra: :P
[19:00:34] <alex_joni> still.. people are paying for this
[19:02:33] <alex_joni> there seems to be an "open-source" roomba
[19:02:52] <maddash> holy crap:
http://hackedgadgets.com/2007/04/20/roomba-with-airsoft-gun-and-laser-sight/
[19:06:12] <skunkworks_> my wife wants one..
[19:06:19] <skunkworks_> (cat hair)
[19:06:36] <lerneaen_hydra> I've got a cat hair generator
[19:06:51] <lerneaen_hydra> runs on hydrocarbons
[19:07:07] <lerneaen_hydra> you can probably find one somewhere around you
[19:07:13] <lerneaen_hydra> they're relatively common
[19:07:55] <cncjunior> hello !
[19:07:57] <skunkworks_> barry is doing good - one more pill. Swelling is going down. I am getting really good at putting the pill down his throat..
[19:08:05] <alex_joni> hehe
[19:08:33] <cradek> hi cncjunior
[19:09:23] <alex_joni> hi cncjunior
[19:10:15] <skunkworks_> berry seems to still like me.. The tuna helps.
[19:10:26] <skunkworks_> cncjunior: hi
[19:10:29] <cncjunior> i ask your help in March for an adaptive control of feed rate / spindle speed
[19:11:01] <cncjunior> it was ok but now the hdd failed
[19:11:18] <alex_joni> :/
[19:12:07] <cncjunior> i don't remember how to link pwm with spindle speed override and parport
[19:12:42] <cradek> cncjunior: if someone helped you on irc, you could search the irc archives
[19:13:10] <alex_joni> cradek: it was mostly in pm's
[19:13:10] <alex_joni> as I was explaining it in romanian :)
[19:13:23] <cradek> oh
[19:13:25] <cncjunior> i read it
[19:14:01] <cradek> make backups folks. your emc configuration will fit on a floppy.
[19:14:06] <alex_joni> cncjunior: feed rate is working?
[19:14:33] <alex_joni> cncjunior: if I remember it correctly you had the following scenario:
[19:14:42] <cncjunior> alex joni : yes, with your help
[19:15:00] <alex_joni> motion.spindle-speed-out connected to pwmgen, and driving the external spindle
[19:15:04] <cncjunior> and all the emc group
[19:15:14] <lerneaen_hydra> cradek: btw, now that there's CSS I assume that there's also feed in units/rev?
[19:15:34] <cradek> yes
[19:15:51] <lerneaen_hydra> is it in the gcode cheat sheet?
[19:15:55] <alex_joni> 2 inputs driving halui.spindle-override.increase and halui.spindle-override.decrease
[19:15:56] <cradek> yes
[19:16:01] <lerneaen_hydra> what happens if there's no spindle speed reported?
[19:16:08] <lerneaen_hydra> no feed?
[19:16:21] <cradek> then you should make a loopback in hal
[19:16:33] <cradek> (there's a spindle speed input)
[19:16:53] <lerneaen_hydra> oh, say you have a mill without spindle speed feedback and you accidently program the wrong feed type
[19:16:55] <cradek> ideally you can get that from your encoder driver's velocity output
[19:17:43] <cradek> sure, if the spindle speed input is 0, it won't move
[19:17:52] <cradek> is that what you're asking?
[19:19:21] <cradek> net spindle-pos pluto-servo.encoder.2.position => motion.spindle-revs
[19:19:22] <cradek> net spindle-speed-fb pluto-servo.encoder.2.velocity => motion.spindle-speed-in
[19:19:37] <cradek> position for threading, velocity for css/fpr
[19:20:59] <anonimasu> hello
[19:22:03] <anonimasu> hym
[19:22:13] <awallin> hi anonimasu
[19:22:13] <anonimasu> hm, the machine will move..
[19:22:22] <anonimasu> though you wont be able to do any cycles and stuff..
[19:22:41] <anonimasu> lerneaen_hydra: you would have to specify _in_cut_ in yoru g-code..
[19:22:44] <anonimasu> or something
[19:25:04] <lerneaen_hydra> cradek: yep that's what I was thinking
[19:25:17] <lerneaen_hydra> cradek: so if there's no hal connection spindle speed will be 0?
[19:25:28] <cradek> I think so
[19:25:43] <lerneaen_hydra> and not inf or something silly ;)
[19:26:53] <alex_joni> spindle-speed-out is in RPS?
[19:27:17] <cradek> no, rpm
[19:27:23] <jepler> unfortunately, it's in RPM
[19:27:39] <cradek> don't tell jmk
[19:27:57] <awallin> radians/s is what everyone would want right?
[19:28:16] <anonimasu> angstrom/s
[19:28:20] <alex_joni> grads/fortnights
[19:28:23] <anonimasu> yep
[19:28:23] <anonimasu> or stones
[19:28:39] <cradek> circular mil inches
[19:29:03] <jepler> personally, I think the in and out should be in rps
[19:29:07] <lerneaen_hydra> internally it's rad/s right?
[19:29:29] <jepler> because spindle position input is in rotations, and velocity should be the derivative of position
[19:29:48] <jepler> and the units of speed out and speed feedback should be the same
[19:29:50] <jepler> rps everywhere
[19:29:54] <cradek> I definitely sympathize with that position
[19:29:57] <jepler> unfortunately it's probably too late to change spindle speed out
[19:31:13] <cradek> I wish someone would offer to send a cd to pato1
[19:32:08] <alex_joni> I could send one..
[19:32:18] <alex_joni> but by the time he gets it.. it's most likely obsolete
[19:32:32] <alex_joni> wasn't jymmm in CA?
[19:35:08] <alex_joni> http://pastebin.ca/616671
[19:35:09] <cradek> spindle speed in is also rpm, so you can loopback, right?
[19:35:16] <alex_joni> yeah, I think so
[19:37:02] <cradek> has anyone tried this:
http://on-disk.com/request.php
[19:37:19] <cradek> it's something else we could recommend to pato1
[19:39:15] <maddash> what's pato1?
[19:39:53] <alex_joni> another AI entity
[19:40:02] <alex_joni> this time sending emails, not IRC
[19:40:46] <alex_joni> cradek: I bet jymm can be nice enough to send him a CD
[19:49:34] <skunkworks_> couldn't you email the cd to him? ;)
[19:49:50] <cradek> no, fax it
[19:50:07] <skunkworks_> volt/rad/sec ;0
http://www.electronicsam.com/images/KandT/servotag.JPG
[19:51:09] <lerneaen_hydra> skunkworks_: sweet :D
[19:52:17] <alex_joni> brb
[19:59:11] <robin_sz> meep?
[20:03:36] <awallin> anyone miss Chippy lately? Here he is in STL:
http://imagebin.org/9331
[20:06:38] <alex_joni> awallin:
http://dsplabs.cs.utt.ro/~juve/emc/tux/
[20:07:35] <awallin> alex_joni: yep, that is where I got the stl file from
[20:08:03] <awallin> it's about 22k triangles which is a bit much for my 'toy' CAM algorithm at the moment...
[20:08:12] <alex_joni> heh
[20:08:18] <alex_joni> that's why it's flat?
[20:08:28] <lerneaen_hydra> alex_joni: hey the files I generated a long time ago are there :)
[20:08:48] <alex_joni> lerneaen_hydra: yup
[20:08:54] <awallin> no the pic should have all the triangles. but running them through my prelim. matlab code would take ages.
[20:09:39] <awallin> the perspective is a bit distorted, that's why it looks flat.
[20:09:47] <alex_joni> a "bit" he says
[20:09:52] <alex_joni> :P
[20:10:00] <lerneaen_hydra> awallin: do you know how many visitors you're averaging per day on your site?
[20:10:14] <awallin> anyway that was a test where I got some python code to read in an STL file and I played around with drawing it in opengl/wxpython
[20:10:19] <awallin> lerneaen_hydra: let me check...
[20:10:28] <lerneaen_hydra> unique visitors
[20:10:51] <robin_sz> difficualt to track unique visitors
[20:11:01] <lerneaen_hydra> yeah, well, "unique"
[20:11:09] <awallin> about 6-7k unique visitors per month. much less now when I've written about math and CAM I bet :)
[20:11:16] <lerneaen_hydra> how many different IP adresses :p
[20:11:19] <lerneaen_hydra> haha
[20:11:19] <awallin> according to the statistics of my host, dot5hosting.com
[20:11:34] <lerneaen_hydra> not bad
[20:11:40] <lerneaen_hydra> oh, not own hosting?
[20:11:51] <alex_joni> bet they stop changing their IP's when you're talking about CAM
[20:12:34] <awallin> "Therefore I verily say unto thee, focus ye not on the Number of those reading your Blog, but on the Content to be written therein."
[20:14:02] <lerneaen_hydra> awallin: I'm more interested in who they are than how many :p
[20:16:09] <anonimasu> how do you convert 20.7lbs/hr to cc/min?
[20:16:33] <lerneaen_hydra> it's 42 cc/min
[20:16:39] <lerneaen_hydra> regardless of density
[20:16:52] <alex_joni> 214cm3/min (20.7 LBS/HR)
[20:17:01] <cradek> you don't because lbs is weight and cc is volume
[20:17:05] <awallin> this one is quite good
http://www.chemie.fu-berlin.de/chemistry/general/units_en.html
[20:17:07] <cradek> (weight, not mass)
[20:17:15] <cradek> I think
[20:17:20] <cradek> or is it mass?
[20:17:23] <anonimasu> im trying to find out the size of some fuel injectors..
[20:17:25] <awallin> mass.
[20:17:25] <lerneaen_hydra> afaik cradek is correct
[20:17:28] <anonimasu> that sounds really small
[20:17:40] <lerneaen_hydra> you need the density
[20:18:03] <awallin> cradek: go to the moon and see how much stuff weighs there! density doesn't change though...
[20:18:05] <cradek> units converts both lb and slug directly into gram - it must assume earth?
[20:18:11] <anonimasu> hehe
[20:18:21] <anonimasu> well, I got to jet..
[20:18:22] <anonimasu> laters
[20:18:32] <cradek> awallin: I know the difference, just not which a lb is
[20:18:53] <jepler> kg is mass
[20:19:15] <awallin> pound-force is used sometimes I guess for force (Newton in SI units)
[20:20:43] <lerneaen_hydra> do people still use non-SI units for real stuff?
[20:21:18] <cradek> lerneaen_hydra: are you trolling or serious?
[20:21:27] <lerneaen_hydra> serious
[20:21:42] <awallin> if you can count US and UK citizens as people...
[20:21:46] <lerneaen_hydra> by real stuff I mean complex engineering/sciences
[20:21:49] <cradek> not in science/physics so much I bet, but in other daily things we do
[20:22:05] <lerneaen_hydra> or rather semi-complex and up
[20:22:15] <awallin> NASA does.
[20:22:19] <lerneaen_hydra> sure your joe sixpack uses miles and inches, but does nasa still mix units?
[20:22:37] <lerneaen_hydra> oh noes
[20:28:28] <cncjunior> thank you for your help !
[20:30:54] <robin_sz> awallin, OI, less of that!
[20:31:50] <robin_sz> awallin, UK has not used lb, oz and inches for years and years
[20:32:06] <robin_sz> theres only 3 places that use them now
[20:32:08] <robin_sz> USA
[20:32:23] <robin_sz> Libya
[20:32:38] <robin_sz> and some other godforsaken hell-hole whose name I have forgotten
[20:33:20] <cradek> ha
[20:33:42] <robin_sz> oops I was wrong
[20:33:43] <robin_sz> USA
[20:33:47] <robin_sz> Burma
[20:33:49] <robin_sz> Liberia
[20:34:26] <robin_sz> to be fair, the USA doesnt even use imperial units as we did in the UK all that time ago
[20:34:47] <cradek> robin_sz: and how many stone do you weigh?
[20:35:00] <cradek> you have to admit that you guys have your own peculiarities still
[20:36:39] <robin_sz> cradek, no clue, ,74kg
[20:37:05] <cradek> heh, sure
[20:37:34] <robin_sz> my wife weighs 47kg ...
[20:38:02] <robin_sz> not a lot :)
[20:43:20] <awallin> robin_sz: now, let's go on to currency. have you heard about the initiative with the same currency in the whole of europe yet ? ;)
[20:43:35] <cradek> heh
[20:43:47] <cradek> awallin: don't laugh - theirs is worth something
[20:44:15] <awallin> the euro is too. it's the dollar thats going down down
[20:44:42] <awallin> but that's good, I can buy a lot of toys on my US trips!
[20:46:48] <awallin> anyone know what the penalty for sin() cos() and tan() functions are compared to squares and square-roots
[20:47:02] <robin_sz> mmm, flogging?
[20:47:08] <awallin> I got the advice that serious performance-code must not use sin() and cos()
[20:47:20] <robin_sz> thats true enough
[20:47:45] <robin_sz> relatively heavyweight functions AIUI
[20:49:11] <awallin> ok, might look into optimizing later. better to do it when some profiling/benchmarking is available
[20:58:30] <robin_sz> http://www.discount-currency-exchange.com/currency-resources/currency-graph.cfm
[20:58:43] <robin_sz> interesting graph .. USD v GPB for the last 5 years
[21:05:16] <awallin> gnight.
[21:18:25] <kanzure> http://opencollector.org/collector.php interesting
[21:18:27] <kanzure> is Linuxcnc on here yet?
[21:18:54] <anonimasu> I bought electrical stuff today for my mill
[21:19:13] <anonimasu> for the electrical cabinet
[21:27:41] <giacus> helloooo
[21:27:44] <giacus> guys :)
[21:27:58] <giacus> how are going ?
[21:30:22] <giacus> wewe
[21:30:31] <giacus> are U around ?
[21:31:09] <giacus> uhm...
[21:31:14] <giacus> :(
[21:32:29] <giacus> I heard about issues using gnome/Kde an graphical interfaces on the ML
[21:33:04] <giacus> I tried to suggest they to swithc to an Usable WM
[21:33:58] <giacus> but the ML replies my IP is banned.. from sbl.spamhaus.org ..
[21:34:04] <giacus> doh!
[21:34:21] <giacus> it's a dinamic IP pleaseeeee unban it
[21:34:23] <giacus> :D
[21:35:17] <\x90> first off this is completely off topic
[21:35:26] <\x90> but if its a dynamic IP then just get a new one
[21:35:35] <\x90> /ipconfig /release
[21:35:38] <giacus> please, consider to try Ion if you need a really Usable Graphical Interface for EMC and old PC !
[21:35:38] <\x90> /ipconfig /renew
[21:35:52] <\x90> ...gnome works fine thanks
[21:35:53] <giacus> what ?
[21:36:09] <giacus> also KDE its fine
[21:36:20] <\x90> pretty much any window manager is
[21:36:22] <\x90> whats your point
[21:36:23] <giacus> also the nwe vista interface its cool
[21:36:32] <\x90> .... thats windows
[21:36:42] <giacus> where U from ?
[21:36:47] <\x90> US
[21:36:51] <giacus> IT
[21:36:55] <\x90> i know
[21:37:13] <giacus> wanna change first minister Prodi with president Bush ?
[21:37:24] <\x90> ...no
[21:37:33] <giacus> why not ?
[21:37:35] <giacus> :(
[21:37:35] <\x90> i wanna wait a couple more years and get somebody else in there
[21:37:39] <giacus> :D
[21:37:40] <\x90> because i dont know your Produ
[21:37:44] <\x90> *prodi
[21:37:44] <giacus> hahah

[22:05:47] <giacus> that's the cheapest cnc around the world running ..
[22:05:50] <\x90> hahaha
[22:05:54] <\x90> mines pretty cheap as well
[22:05:56] <giacus> :D
[22:06:06] <giacus> I wanna show U antoher thing wait ..

[22:07:28] <giacus> never eat
[22:07:41] <giacus> something diferent of meditarreney
[22:07:53] <lerneaen_hydra> giacus: is that standard threaded rod as your screw for Y?
[22:07:56] <giacus> what are you going to eat ??
[22:08:05] <giacus> hey lerneaen_hydra :)
[22:08:38] <\x90> back
[22:08:52] <lerneaen_hydra> that was fast
[22:08:53] <\x90> giacus: i was going to eat some frozen mac and cheese
[22:08:55] <maddash> holy shit, he milled a cat!
[22:09:00] <\x90> yeah i didnt actually eat
[22:09:04] <maddash> oh, nvm
[22:09:07] <\x90> looked in the freezer and decided against it
[22:09:10] <\x90> haha maddash
[22:09:27] <lerneaen_hydra> maddash: err, some obscure reference?
[22:10:01] <\x90> lerneaen_hydra: the pictures he posted
[22:10:05] <\x90> his cat is sitting on the mill
[22:10:13] <maddash> lerneaen_hydra: the first picture. my nearsightedness
[22:10:33] <lerneaen_hydra> ah on the chair
[22:10:37] <lerneaen_hydra> outside the mill :p
[22:10:48] <\x90> haha
[22:10:56] <giacus> \x90: cosdier to use a nice wallpaper on windows vista:
http://www.giacus.org/files_old/001_1024x768.png
[22:10:58] <giacus> :D
[22:11:02] <maddash> is it just me, or is one of his ballscrews rusted?
[22:11:03] <giacus> ;)
[22:11:10] <\x90> haha
[22:11:21] <\x90> giacus: do you do povray?
[22:11:21] <lerneaen_hydra> maddash: heh, ballscrews
[22:11:33] <\x90> i think thats threaded rod from the hardware store
[22:11:55] <lerneaen_hydra> \x90: looks like it
[22:12:00] <giacus> \x90: sorry .. I just know how to use a keyboard.. don't know about powray ..
[22:12:02] <giacus> :P
[22:12:03] <maddash> rofl I hope AXIS never requires such a large manual
[22:12:05] <lerneaen_hydra> well it's cheap at least
[22:12:14] <\x90> haha giacus
[22:12:17] <\x90> its a nice render
[22:12:21] <giacus> but I think powray should be a nice thing :D
[22:12:23] <giacus> yeah
[22:12:27] <giacus> no no ..
[22:12:30] <giacus> really
[22:12:39] <giacus> isnt powray
[22:12:44] <\x90> oh
[22:12:44] <\x90> what is it?
[22:12:57] <giacus> emacs!
[22:12:58] <giacus> :D
[22:13:01] <\x90> ...
[22:13:03] <\x90> you have to be kidding
[22:13:04] <lerneaen_hydra> O_o
[22:13:14] <lerneaen_hydra> wasn't it blender you made it in?
[22:13:15] <giacus> :)
[22:13:20] <giacus> yeah
[22:13:25] <giacus> Blender
[22:13:26] <\x90> haha
[22:13:31] <\x90> what renderer?
[22:13:52] <lerneaen_hydra> iirc there's a raytracing renderer integrated in it
[22:14:08] <\x90> oh
[22:14:09] <\x90> hm
[22:14:52] <giacus> :D
[22:15:01] <giacus> kidding ..
[22:15:23] <\x90> giacus: this is my old mill
[22:15:24] <\x90> http://www.crepinc.com/projects/cnc-mill/
[22:15:29] <\x90> my new one is nicer, but not done yet
[22:15:45] <giacus> looking
[22:16:59] <lerneaen_hydra> \x90: that sure is one diminutive mill you've got
[22:17:30] <\x90> no kidding
[22:17:35] <lerneaen_hydra> \x90: you run it in your bedroom? :D
[22:17:43] <\x90> i did then yes
[22:17:42] <lerneaen_hydra> college student?
[22:17:46] <giacus> \x90: that's cool
[22:17:48] <\x90> mostly to make PCBs
[22:17:48] <\x90> yah
[22:17:49] <giacus> congrats
[22:17:52] <\x90> thanks
[22:18:02] <lerneaen_hydra> well then that makes us two :)
[22:18:07] <\x90> what school?
[22:18:09] <lerneaen_hydra> which course are you going?
[22:18:13] <giacus> but I'm really against any copyright
[22:18:19] <lerneaen_hydra> chalmers, gothenburg, sweden
[22:18:26] <lerneaen_hydra> electrical engineering
[22:18:26] <giacus> I Think in copyleft attitude
[22:18:33] <\x90> lerneaen_hydra: electrical engineering and mechanical
[22:18:38] <\x90> worcseter polytech
[22:18:41] <lerneaen_hydra> sweet
[22:18:43] <\x90> *worcester
[22:18:44] <\x90> yah
[22:18:47] <\x90> sweden eh?
[22:18:52] <giacus> but it's a nice job
[22:18:57] <lerneaen_hydra> yeah, bork bork and all
[22:19:02] <\x90> hahahahaha
[22:19:05] <giacus> :)
[22:19:56] <\x90> whats it like there anyway
[22:20:01] <\x90> i no thats a huge quetsion
[22:20:05] <\x90> *question
[22:20:19] <lerneaen_hydra> oh, slow and rather commie, otherwise it's OK I guess
[22:20:24] <\x90> commie eh?
[22:20:43] <lerneaen_hydra> yeah, been way left since way back
[22:20:53] <\x90> that would work for me
[22:21:00] <lerneaen_hydra> then again I'm an ex-yankee so that may not say much
[22:21:07] <giacus> \x90: here's some my old job
http://digilander.libero.it/jackydgl0/photos/lab/img010.jpeg
[22:21:10] <\x90> where were you born?
[22:21:16] <\x90> giacus: oh cool
[22:21:19] <giacus> I just work on wood
[22:21:19] <maddash> adios.
[22:21:24] <giacus> yeah
[22:21:32] <lerneaen_hydra> usa, lived there till I was 12-ish
[22:21:39] <giacus> aluminium its too hard
[22:21:38] <\x90> i use the huge mills here to do Mech Eng on Al and Steel
[22:21:41] <\x90> lerneaen_hydra: ah where?
[22:21:51] <lerneaen_hydra> seattle mainly
[22:22:08] <lerneaen_hydra> giacus: how long did it take to make one of those?
[22:22:11] <lerneaen_hydra> couple hours?
[22:22:20] <\x90> i like seattle a lot
[22:22:26] <lerneaen_hydra> yeah it's not at all bad
[22:22:37] <giacus> lerneaen_hydra: was fast enough
[22:23:02] <giacus> for any job about 1 hour
[22:23:11] <giacus> the probelm was another
[22:23:28] <lerneaen_hydra> oh, not bad
[22:23:56] <giacus> burning the tool cause it the rpm was too much slow
[22:24:12] <\x90> oh yeah you cant use coolant i guess
[22:24:17] <giacus> nope
[22:24:39] <giacus> no one wpuld use any coolant on wood works
[22:25:03] <giacus> you just need high rpm's
[22:25:06] <lerneaen_hydra> bah, it's late here now
[22:25:07] <giacus> on router
[22:25:09] <lerneaen_hydra> later all
[22:25:14] <giacus> to avoid to burn the tools
[22:25:16] <toastyde1th> cold air
[22:25:22] <\x90> later lerneaen_hydra
[22:25:24] <giacus> nah..
[22:25:35] <giacus> isnt enough
[22:25:44] <toastyde1th> cold air isn't enough?
[22:25:47] <\x90> heh toastyde1th we've got some liq nitrogen here, could use that
[22:25:49] <giacus> yeah
[22:25:51] <toastyde1th> -30 C air
[22:25:54] <giacus> isnt enough
[22:26:05] <toastyde1th> which people use to rough stainless at high speed
[22:26:07] <toastyde1th> won't work for wood?
[22:26:16] <toastyde1th> whyever not
[22:26:27] <giacus> you need the right rpm's for the job you're running
[22:26:34] <toastyde1th> what's that got to do with cold air
[22:26:36] <toastyde1th> as a coolant
[22:26:48] <giacus> otherwise you'll burn the tool
[22:26:57] <toastyde1th> that's true of any machining operation
[22:27:03] <giacus> not on wood
[22:27:07] <toastyde1th> but why?
[22:27:18] <toastyde1th> RPM doesn't have anything to do with your choice of coolant
[22:27:45] <giacus> because for what I know air coolant inst enough
[22:27:51] <toastyde1th> okay, that's not a very good answer
[22:28:22] <toastyde1th> air will keep the tool cold and keep the dust off the cutter
[22:28:31] <giacus> you need the right RPM and the right speed axis
[22:28:31] <\x90> ^^
[22:28:43] <giacus> to get a good job
[22:28:45] <toastyde1th> giacus: that's true of any machining operation ever preformed
[22:28:57] <toastyde1th> they knew that back in the stone age with bow drills
[22:29:01] <giacus> :P
[22:29:06] <giacus> is it ?
[22:29:12] <toastyde1th> it doesn't have a bloody thing to do with coolant
[22:29:29] <JymmmmEMC> toastyde1th: quit being so difficult young lady!
[22:29:33] <toastyde1th> I WANT ANSWERS
[22:29:37] <giacus> hahaha
[22:29:37] <\x90> haha
[22:29:45] <\x90> i think toastyde1th has some good points
[22:29:45] <giacus> guys
[22:29:49] <giacus> I must go ..
[22:29:52] <toastyde1th> speed and feed have nothing to do with coolant
[22:29:58] <toastyde1th> and dry, frigid air
[22:29:59] <giacus> see you next timne!!
[22:30:02] <toastyde1th> is an excellent coolant.
[22:30:07] <JymmmmEMC> laters giacus
[22:30:10] <giacus> ciaooo :)
[22:30:24] <JymmmmEMC> toastyde1th: try that on your gf and see what happens!
[22:30:26] <giacus> ciao JymmmmEMC
[22:30:36] <toastyde1th> dry, frigid air?
[22:30:42] <toastyde1th> i'd imagine she'd get frostbite inside of a couple minutes
[22:31:02] <\x90> lol
[22:31:07] <JymmmmEMC> toastyde1th: and you wont get any for a year!
[22:31:07] <\x90> youd get frozen in
[22:31:40] <toastyde1th> what an embarassing hospital visit
[22:31:44] <\x90> ok really getting food this time
[22:31:45] <\x90> * \x90 brb
[22:32:34] <toastyde1th> but seriously guys
[22:32:41] <toastyde1th> what does feed and speed have to do with coolant in relation to cutting wood
[22:36:09] <toastyde1th> oh booyah
[22:36:32] <toastyde1th> cold air system manufactuers explicitly state wood as one of uses for cold air
[22:37:15] <\x90> i concur
[22:37:21] <\x90> though i admit i've only ever cut metal and plastic
[22:38:07] <\x90> heh #emc taught me to machine
[22:38:13] <\x90> i'd never cut anything when i built my first mill
[22:38:20] <\x90> and you guys taught me how it all worked
[22:38:22] <\x90> now i do it for a living....
[22:40:13] <toastyde1th> ha
[22:59:35] <anonimasu> :)
[22:59:39] <anonimasu> \x90: nice!
[22:59:52] <\x90> thanks
[23:00:00] <anonimasu> toastyde1th: hm, speed and feed to affect if you need coolant.
[23:01:06] <toastyde1th> speed and feed do not mandate or bar the use of coolant
[23:01:13] <toastyde1th> unless you're using specific tooling
[23:01:15] <anonimasu> no, tool friction do..
[23:01:20] <toastyde1th> which is not compatable with wood
[23:01:23] <anonimasu> yep..
[23:02:13] <anonimasu> toastyde1th: and material..
[23:02:21] <toastyde1th> you are missing the point i am making
[23:02:37] <toastyde1th> he is saying, in response to "why isn't air an acceptable coolant"
[23:02:44] <toastyde1th> that you have to select feed and speed or burn your cutter up
[23:02:48] <toastyde1th> two completely unrelated things
[23:02:53] <anonimasu> ah, yeah.
[23:03:25] <toastyde1th> we could go into thermal shock, tribology, various kinds of wear, et cetera
[23:03:31] <anonimasu> yeah..
[23:03:37] <toastyde1th> if we wanted to discuss the parameter/coolant relationship
[23:03:44] <anonimasu> the nastiness.. of machining
[23:03:58] <toastyde1th> i just want to know why someone would say using wood completely eliminates all choices of coolant in the process
[23:04:14] <anonimasu> * anonimasu nods
[23:04:19] <\x90> probably because thats how hes done it all his life
[23:04:22] <anonimasu> I dont know about wood..
[23:04:51] <\x90> im used to 0.0001" tolerances... i dont think i can do that in wood
