[00:00:22] <andypugh> For your next trick, iron castings in place of wood...
[00:00:28] <djdelorie> the top grid didn't have enough clearance and scraped the copper, the bottom one had too fast Z and snapped the bit.

[00:00:45] <Jymmm> djdelorie: Interesting results... https://www.google.com/search?q=servo+tuning
[00:00:49] <djdelorie> nah, I just need stronger wood :-)
[00:01:02] <djdelorie> Jymmm: thanks

[00:04:17] <pfred1> yeah DJ needs a more solid machine
[00:04:34] <djdelorie> next time: rock maple! :-)
[00:05:32] <WillenCMD> alright, any taker's on why i tklinuxcnc screen won't work in sim mode?
[00:05:42] <pfred1> you need to get a surplus pick and place machine or something
[00:06:07] <pfred1> I use tkemc as my interface
[00:06:47] <WillenCMD> i just finished installing lubuntu
[00:07:13] <WillenCMD> i got the linuxcnc-dev sim working... but it won't load tklinux
[00:07:37] <pfred1> maybe you don't have the right version of Tcl/TK ?
[00:07:41] -!- Valen [Valen!~Valen@c122-108-45-139.blktn6.nsw.optusnet.com.au] has joined #linuxcnc
[00:08:04] <WillenCMD> possible, i ran dpkg-checkbuildep
[00:08:28] <pfred1> if you did that it is unlikely I don't know which version you need
[00:08:41] <pfred1> it worked for me in Debian Lenny though
[00:08:50] <pfred1> and i didn't install anything special for it
[00:09:01] <WillenCMD> i think cradek said he had it working on lubuntu yesterday on here
[00:09:27] <pfred1> cradek got me going when I had everything installed but I didn't know how to run any of it
[00:09:44] <pfred1> oh wait what commands are you issuing?
[00:10:23] <ReadError> ;-o
[00:10:25] <WillenCMD> im running the script in shell, via clicking on the linuxcnc in the scripts folder
[00:10:29] <pfred1> there is a . /linuxcnc-environment;tklinuxcnc
[00:10:29] <ReadError> so excited!
[00:10:35] <ReadError> its all coming together!
[00:10:41] <ReadError> cnc parts, wednesday
[00:10:46] <ReadError> mill, thursday
[00:10:49] <pfred1> or something like that
[00:10:52] <ReadError> days off, thur, fri, sat
[00:10:55] <ReadError> ;o
[00:11:14] <pfred1> you have to hand load the environment for rtai if it isn't going
[00:11:15] <ReadError> machinist square, wednesday too
[00:11:55] * pfred1 just uses up arrow in his shell a lot so forgets things ...
[00:11:59] <ReadError> now, i hope a2z ships today ;)
[00:12:24] <WillenCMD> rip-environment
[00:12:28] <WillenCMD> correct?
[00:12:35] <pfred1> WillenCMD maybe I run emc2
[00:12:54] <andypugh> djdelorie: The extruded aluminium section is easy to work with and might (or might not) be more rigid. Also, ballscrews are not enormously expensive from the right sources.
[00:13:03] <pfred1> but now that you mention it I believe it is rip-environment
[00:13:18] <djdelorie> andypugh: I'm happy I got one *anything* working :-)
[00:13:29] <pfred1> not doing that would stop tklinuxcnc from going
[00:13:37] <andypugh> http://www.8020.net/
[00:13:49] <pfred1> oh here we go 8020
[00:13:52] <WillenCMD> djdelorie: linearmotionbearings on ebay, great price i paid 315 shipped for 3 screw's with nuts, all endmounts, and couplings
[00:14:07] <djdelorie> how long?
[00:14:21] <WillenCMD> hmmm let me lood it up
[00:14:25] <WillenCMD> look*
[00:14:52] * djdelorie has dreams of a 5x10 foot bed for the next machine...
[00:14:59] <joe9> this is my custom.hal with software debounce: http://codepad.org/FsWIrQwK . I still get the error message: http://codepad.org/ad5WlCvc Error message: "Home switch inactive before start of backoff move"
[00:15:01] <pfred1> I've seen people just piss 8020 away
[00:15:22] <andypugh> WillenCMD: I consider that expensive. http://www.zappautomation.co.uk/sf1204-single-ballnut-p-137.html
[00:15:37] <JT-Shop> joe9: could be mechanical
[00:15:39] <djdelorie> joe9: that means the switch bounced "off" before it shut off because the axis moved
[00:16:13] <joe9> djdelorie: i noticed that all the time on X-axis. played around with the delay of 15, 20 and 5 in the custom .hal
[00:16:18] <joe9> without any effect.
[00:16:19] -!- micges has quit [Ping timeout: 252 seconds]
[00:16:28] <djdelorie> my debounce is 0.1 seconds
[00:16:29] <joe9> now, it is happening on the X-axis too.
[00:16:39] <andypugh> joe9: Halscope might help figure it out.
[00:16:41] -!- micges_atom has quit [Ping timeout: 252 seconds]
[00:16:44] <JT-Shop> joe9: do you have a photo of your switch setup?
[00:16:45] <djdelorie> but mine has no delay on activation, just release
[00:17:00] <pfred1> andypugh how does software limits interact with switch limits?
[00:17:12] <pfred1> like does it help linuxcnc hunt for the switches?
[00:17:45] <joe9> djdelorie: can you please paste your custom.hal?
[00:17:55] <pfred1> what I'm driving at is could joe's soft limits be so far off that is why he is missing his switch limits?
[00:18:03] <joe9> djdelorie: I have your .ini and .hal file and machineactive.comp
[00:18:06] <djdelorie> joe9: it's still all here: http://www.delorie.com/cnc/
[00:18:10] <djdelorie> that's all I've got
[00:18:25] <andypugh> pfred1: Not as far as I know. During homing it can't know where it is, so ignores both. After homing hitting the physical switches indicates an error.

[00:20:24] <WillenCMD> <==halscope=my best friend
[00:20:32] <andypugh> WillenCMD: Any errors in dmesg when you try to start tk? Does it also fail in non-sim mode?
[00:20:46] <ReadError> guess theres no way to test latency w/o the motors and all hooked up?
[00:21:00] <WillenCMD> i haven't installed linuxcnc just trying to run it from sim mode, i designed a new tklinux screen, that i want to try
[00:21:01] <pfred1> ReadError why not?
[00:21:06] <andypugh> ReadError: Yes, there is absolutely no need to have any hardware for a latency test
[00:21:09] <ReadError> does it not need the feedback?
[00:21:10] <ReadError> ohrly
[00:21:15] <ReadError> i should get the box running!
[00:21:18] <ReadError> ;o
[00:21:26] <WillenCMD> andypugh: but i need to get the original working first
[00:21:36] <andypugh> You can pick the latency test right from the CNC menu
[00:21:56] <pfred1> this machine did it and it doesn't even have a parallel port
[00:22:04] <andypugh> (I think, I don't have a normal install any more...)
[00:22:22] <andypugh> All you need for a latency test is the RTAI kernel.
[00:22:40] <pfred1> I've done the CLI latency test that comes with RTAI
[00:22:49] <pfred1> it is pretty strange
[00:23:02] <pfred1> there are actually two of them I believe
[00:23:28] <r00t4rd3d> http://www.sparkfun.com/products/10847
[00:23:31] <andypugh> Yes, and they both give different numbers to the graphocal one. This is a point of concern...
[00:23:31] <r00t4rd3d> anything bad about those?
[00:23:45] <pfred1> oh you've seen them too?
[00:24:11] <pfred1> well if you use axis as your front end won't evne the latency test kick in GL?
[00:24:12] <WillenCMD> i ordered, a spartan 3e dev board today, 2x atmel xmega dev boards, and a altera cyclone II dev board today... can't wait
[00:25:02] <WillenCMD> couldn't decide on wich fpga manufacturer to go with, so i got one of each
[00:25:03] <pfred1> I know GL makes some of my machines "different" when it is going on
[00:25:15] <djdelorie> while I was out yesterday, a friend dropped off a single linear axis (no stepper). What interesting things can you do with just one axis?
[00:25:37] <djdelorie> WillenCMD: you need a Lattice board too, then :-)
[00:25:38] <pfred1> djdelorie you can make a CNC router fence adjuster
[00:25:48] <pfred1> or perhaps a router lift
[00:25:59] <WillenCMD> or a tool changer
[00:26:12] <pfred1> heck make a 4th axis
[00:26:17] <r00t4rd3d> make it scratch your back while you wait for a cut
[00:26:26] <pfred1> 4 axis CNC is da bomb
[00:26:26] <WillenCMD> lol
[00:26:34] <andypugh> r00t4rd3d: They look OK. Fairly small, but that probably means they are fairly quick. I would suggest working out for yourself which windings are which, and which ends are which, because my experience with 8-wire steppers is that the docs may be wrong. couple A1 and A2 back-to-back and you get full current and zero torque. It is as simple as shorting wires together and spinning the shaft by hand to figure it out.
[00:26:40] <WillenCMD> no 5 axis is the bomb
[00:26:48] <pfred1> andypugh show djdelorie some of your 4 axis CNC stuff
[00:27:07] <skunkworks__> andypugh: and welcome back also!
[00:27:13] <pfred1> that last video I saw of yours was crazy
[00:27:20] <r00t4rd3d> andypugh, they are 6 wire and I already know the layout of them
[00:27:31] <r00t4rd3d> yellow and white I dont need
[00:27:31] <andypugh> I don't have any 4-axis stuff. Which video do you mean?
[00:27:51] <andypugh> Ah, 6-wire is easier, you just need to ignore wires :-)
[00:27:55] <pfred1> you have one where yo uhave something chucked in your machine and you're threading it?
[00:28:04] <djdelorie> http://www.delorie.com/photos/cnc/linear-rail.html
[00:28:13] <r00t4rd3d> "This is a uni-polar stepper, meaning that if you are going to drive it with a bipolar stepper driver, you can ignore the yellow and white leads and drive it using the remaining four."
[00:28:22] <r00t4rd3d> :D
[00:28:37] <pfred1> can't make a 4th axis with that
[00:28:40] <andypugh> djdelorie: Nice!
[00:29:03] <djdelorie> of course, he might have dropped it off so I can tell him how to use it in *his* machine :-)
[00:29:03] <r00t4rd3d> are those limit switch wires?
[00:29:19] <djdelorie> I think so. Three conductor connectors
[00:29:26] <pfred1> it'd make for a long Z axis
[00:29:41] <r00t4rd3d> carve a stump
[00:29:53] <andypugh> pfred1: This is my channel: http://www.youtube.com/user/blyndpew?feature=guide I am not sure which one you mean.
[00:29:54] <WillenCMD> so when i launch tklinux, i don't get anything not even a debug message

[00:31:00] <andypugh> WillenCMD: Odd. I know of several reasons that you might be able to run tklinux but not Axis (mainly OpenGL related) tbut the inverse problem puzzles me.
[00:31:05] <joe9> djdelorie: is it this file: machineactive.comp that is doing the activate on release?
[00:31:25] <djdelorie> no, my debounce is inside the controller cards.
[00:31:39] <djdelorie> machineactive.comp is a combined "the machine is doing something" signal I use to idle the motors
[00:31:43] <ReadError> wow, that is AWESOME
[00:31:48] <WillenCMD> i know... i thought would be safe designing my screens in tk/tcl
[00:31:52] <pfred1> djdelorie this is andypugh http://www.youtube.com/watch?v=ZhICrb0Tbn4&list=UUexvgsGz_QFvOublovDYoTQ&index=14&feature=plcp
[00:32:07] <alex_joni> WillenCMD: try running linuxcnc from a terminal, and check for any messages
[00:32:45] <r00t4rd3d> there goes your 733 minutes of idle
[00:35:01] -!- elmo40 has quit [Quit: Leaving.]
[00:35:36] <djdelorie> joe9: you could probably adapt machineactive.comp to be an asymmetric debouncer...

[00:36:49] <Valen> dude pastebin
[00:36:55] <pfred1> I'm telling you
[00:37:03] <Valen> also how no excess flood
[00:37:12] <WillenCMD> what?
[00:37:29] <djdelorie> I don't know how to tie a comp's input to a fixed value in hal, but if you tied its estop and velocity pins to 0, you could use the running->active path to debounce
[00:37:30] <pfred1> WillenCMD http://pastebin.com/
[00:37:30] <Valen> generally pasting a block of text will get you kicked off the network
[00:38:01] <djdelorie> worse, the server will pace the output to one line per second, and all the clients beep once per message, so... beep. beep. beep. beep.
[00:38:22] <WillenCMD> sorry
[00:38:29] <WillenCMD> won't happen again
[00:38:47] <andypugh> djdelorie: If you don't net a comp input you can setp it in the HAL file.
[00:38:48] <pfred1> it just makes it easier for folks to study it too
[00:39:06] <djdelorie> example?
[00:39:09] <WillenCMD> im new to all this so, bare with me
[00:39:32] <andypugh> (you can also setp parameters, which don't use shared memory, but are otherwise a bit redundant)
[00:39:47] <djdelorie> yeah, the timeout has a default
[00:42:01] <andypugh> djdelorie: loadrt machineactive / setp estop 0 / setp velocity 0
[00:42:20] <djdelorie> ah, you can set it in hal
[00:42:26] <andypugh> Indeed.
[00:42:40] <djdelorie> is there a way to specify a default for unconnected pins, from within the comp ?
[00:42:47] <pfred1> is there anything andy can't set in hal?
[00:42:51] <WillenCMD> http://pastebin.com/DQ17TpTJ
[00:42:55] <WillenCMD> thats better
[00:43:01] <joe9> setp debounce.0.delay 10
[00:43:11] <andypugh> Yes, pin in but running = 0 "this has a default now"
[00:43:21] <andypugh> (but/bit)
[00:43:28] <joe9> is what I have in my custom.hal. I have a base period of 26000 and a search velocity of 1mm/sec
[00:44:26] <WillenCMD> is it odd that LINUXCNC DIR= is empty
[00:44:34] <joe9> is it wrong to do: setp debounce.0.delay 1000000
[00:44:50] <joe9> sorry that is too much.
[00:45:08] <joe9> let me calculate a better value to give me 1 sec latency or debounce period.
[00:45:10] <djdelorie> updated, compiled, untested: http://www.delorie.com/cnc/machineactive.comp
[00:46:24] <jdhnc> 1 second debounce?
[00:46:37] <joe9> is it wrong to do: setp debounce.0.delay 38461
[00:46:47] <joe9> to give a 1 sec debounce period.
[00:46:48] <djdelorie> I used 0.1 second
[00:47:14] <joe9> djdelorie: setp debounce.0.delay 3846 then?
[00:47:34] <djdelorie> joe9: I don't know if that's the right value, just saying my debounce is 0.1 second
[00:47:52] <djdelorie> bounce tends to be in the tens of milliseconds range worst-case
[00:49:36] <pfred1> Don Lancaster could tell you how to debounce a switch :) http://www.tinaja.com/
[00:50:19] <pfred1> he's probably do it with a postscript script today though

[01:07:48] <pfred1> WillenCMD what is looking for linuxcnc tklinuxcnc?
[01:08:36] <andypugh> Might be a problem with the EMC to LinuxCNC name change
[01:09:36] <andypugh> Maybe nobody checked that the tkemc interface still worked when called tklinuxcnc.
[01:10:09] <andypugh> <Insert rant about lawyers and copyright here>
[01:10:18] <WillenCMD> lol understandable
[01:10:30] <WillenCMD> im sure alot went into that
[01:10:35] <pfred1> I'm not upgrading my old emc2
[01:10:52] <WillenCMD> i prefer LinuxCNC gotta good ring to it
[01:11:20] <andypugh> pfred1: Cool new features exist. I even wrote some of them :-)
[01:11:55] <pfred1> andypugh I ran the live CD on this machine
[01:12:08] <WillenCMD> looks like i might need to download the older source
[01:12:11] <pfred1> just to check this thing out
[01:12:44] <andypugh> Though I have a feeling that mhaberler is going to end up producing an emc3 which will make a lot more sense and will allow a lot more cool stuff.
[01:12:52] <pfred1> andypugh someone in another channel asked In the UK what is the mains electricity? (220. 50hz?)
[01:13:25] <pfred1> I figure you'd know this one
[01:13:32] <WillenCMD> its 220 50hz
[01:13:45] <WillenCMD> here in the us its 110 60hz
[01:13:56] <pfred1> more like 120
[01:14:08] <pfred1> which is really split 240
[01:14:23] <WillenCMD> true, most homes have two hot 120 lines coming in from the mains
[01:14:31] <WillenCMD> key word "most"
[01:14:47] <pfred1> seriously there are unbalanced services?
[01:15:29] <pfred1> I've seen some messed up electrical systems but I haven't run into a single legger yet
[01:15:58] <WillenCMD> i don't know i haven't seen this in person, but when doing some research on transformer's a while back i came apon a few threads of people claiming to have only 1 hot line from the main
[01:16:02] <WillenCMD> i think it was a town house
[01:16:08] <andypugh> pfred1: It's 230V +15% - 5% 50Hz to match the Euro 230V +/- 10% (so we match with a nominal 240 compared to their nominal 230)
[01:16:41] <pfred1> andypugh k I'll relay that thanks
[01:17:11] <WillenCMD> damn nice specific answer
[01:18:17] <andypugh> Its a great example of Euro harmonisation by changing the specification, not the facts.
[01:18:43] <pfred1> our electrical system is how it is because Tesla had a thing for 3
[01:19:05] <andypugh> We have 440V three-phase too.
[01:19:14] <pfred1> we do too
[01:19:33] <pfred1> 3 phase is a different service
[01:19:50] <pfred1> yo may or may not be able to get it here
[01:20:11] <andypugh> The mad thing is that we recently euro-harmonised wiring colours to that 3-phase can have blue as neutral or live, and black as neutral or live..
[01:20:25] <pfred1> nice
[01:20:31] <pfred1> early electrician retirement plan
[01:21:38] <andypugh> I may be misremembering
[01:23:10] <andypugh> No, sadly I am not: http://electrical.theiet.org/wiring-regulations/cable-colours/flyer.cfm?type=pdf
[01:24:24] <pfred1> that is spooky
[01:26:44] -!- phantoxe has quit []
[01:35:26] <alex_joni> WillenCMD: it says you're running in place (compiled it yourself)..
[01:35:44] <WillenCMD> yes
[01:35:45] <alex_joni> before you run linuxcnc, you need to source scripts/linuxcnc-environment
[01:35:51] <alex_joni> . scripts/linuxcnc...
[01:36:03] <alex_joni> then try to run 'linuxcnc'
[01:37:17] <pfred1> they need to load the rip-environment
[01:38:01] <WillenCMD> wher is linuxcnc-environment?
[01:38:13] <pfred1> I got the name wrong it is rip-environment now
[01:38:13] <WillenCMD> i used rip-environment
[01:38:32] <pfred1> well you have to envoke it like this . rip-environment
[01:38:42] <pfred1> the dot is important but don't ask me why
[01:38:52] <pfred1> because I've no idea
[01:38:54] <alex_joni> pfred1: that's short for 'source'
[01:39:15] <pfred1> source?
[01:39:23] <pfred1> I know ./ is cwd
[01:39:41] <pfred1> but just . ?
[01:39:53] <andypugh> . ./ is some kind of linux wicca
[01:40:00] <pfred1> linuxcnc is the only place I've ever run into it
[01:40:14] <jdhnc> some put that in the path
[01:40:24] <jdhnc> then you don't need the ./
[01:40:51] <alex_joni> pfred1: it tells the current shell to load (aka source) the contents of the file into the environment
[01:41:02] <alex_joni> like adjusting PATH and such
[01:41:15] <pfred1> ah like export
[01:41:17] <WillenCMD> WOOT
[01:41:24] <WillenCMD> thank you thank you
[01:41:34] <WillenCMD> it was the damn decimal point
[01:41:34] <pfred1> so . rip-environment worked?
[01:41:40] <andypugh> It was that simple? <embarassed>
[01:41:44] <WillenCMD> lol
[01:41:53] <alex_joni> pfred1: yes, but a bunch of them at once ;)
[01:41:58] <WillenCMD> thanks for everyones help
[01:42:08] <pfred1> the freaking environment is outta control on Linux anymore
[01:42:29] <alex_joni> WillenCMD: sure thing
[01:42:40] <alex_joni> andypugh: you're still in the US?
[01:42:48] <jdhnc> mostly unrelated, but anyone ever make a NMEA2000 interface with a uC?
[01:43:12] <pfred1> is NMEA NEMA?
[01:43:18] <alex_joni> gps?
[01:43:29] <alex_joni> pfred1: nope
[01:43:34] <jdhnc> gps and lots of other things
[01:44:01] <alex_joni> jdhnc: nope, just simple serial link to GPS'ses
[01:44:12] * pfred1 has just spent his life honing his indian tracking skillz
[01:44:14] <alex_joni> but the lines from them start with NMEA..
[01:44:25] <andypugh> alex_joni: No, I got back on Saturday.
[01:44:31] <jdhnc> that's NMEA 0183
[01:44:33] <pfred1> we don't need no stinking gps!
[01:44:59] <WillenCMD> learned alot today, learned about pastebin.com(the hard way)
[01:45:16] <pfred1> actually you got off easy
[01:45:32] <pfred1> most chans a 4 line paste is an auto kickban
[01:45:39] <alex_joni> andypugh: still jet lagged?
[01:45:59] <alex_joni> either that or really late up ;)
[01:46:00] <andypugh> No, as I slept from 4pm local to 7am local :-)
[01:46:25] <alex_joni> sounds good ;)
[01:46:29] <andypugh> <checks clock> Hmm, still not into phase though.
[01:46:39] <alex_joni> yeah, 5am coming up here :D
[01:46:48] <pfred1> time is relative to the observer
[01:46:57] <WillenCMD> can i altinstall a different python version?
[01:47:28] <alex_joni> WillenCMD: you can try.. but you're most likely to wreck it ;)
[01:48:05] <pfred1> I think for the next human leap we have to set it up so the whole planet is either daytime or nighttime at the same time
[01:48:28] <pfred1> this planet rotating around the Sun stuff is a pain
[01:48:33] <WillenCMD> pfred1: i agree, its a pain trying to talk to distributor's in china
[01:48:51] <WillenCMD> when im going to bed, thats when they want to call for a meeting
[01:49:38] <alex_joni> well.. I'm off to bed, sun coming up soon
[01:51:48] <andypugh> It was interesting during the sail, we put in an arbitrary 2hr shift whenever sunrise seemed a bit early.
[01:52:36] -!- atom1 has quit [Quit: Leaving]
[01:52:42] <djdelorie> for me, "sun coming up early" means I stayed up too late...
[01:53:15] <pfred1> it is peaceful at night though isn't it?
[01:53:43] <djdelorie> mostly, yeah. I get a lot done at night
[01:54:10] <andypugh> Well, on the boat working 4hrs one / 4 hrs off 24/7 time takes on a more arbitrary aspect.
[01:54:32] <andypugh> (one/on)
[01:54:46] <pfred1> I've worked the late shift after that one hour is much like the next
[01:55:03] <jdhnc> http://tinyurl.com/75rn3l4
[01:55:09] <jdhnc> That was 40 miles offshore here the other day.
[01:55:18] <djdelorie> my dad worked on a tugboat most of his life. 6on/6off for three weeks, then three weeks off...
[01:56:35] <andypugh> jdhnc: We had more of : http://www.sail-world.com/photos_2010/Alt_California%20surf%20down%20a%20wave1.jpg (that's my 68' boat in the previous race)
[01:56:53] <andypugh> (after the mast fell off)
[01:57:21] <jdhnc> wow, that doesn't really look like fun.
[01:57:39] <andypugh> Luckily the big stick stayed on this year, which I view as a good thing.
[02:00:29] <andypugh> jdhnc: With no mast, no fun at all. With a working boat and spinnaker set? YeeHaaa! 27kts on a surf :-)
[02:02:01] <jdhnc> I'm a small boat kinda guy... seas like that just scare me :)
[02:04:04] <pfred1> I'm a land lubber
[02:05:04] <andypugh> On a 68' boat anything less than 20kts is a bit slow, and you are still racing under reef 3 and storm jib at 50kts. Above that you look at trysail and looking after the boat.
[02:05:25] <pfred1> shiver me timbers!
[02:06:31] <Valen> you own the boat?
[02:06:49] <andypugh> Good heavens no, it cost 1,000,000
[02:07:00] <Valen> was about to say andypugh butty mate pal
[02:07:01] <andypugh> www.clipperroundtheworld.com
[02:07:12] <Valen> i never got the point of 4 on 4 off
[02:07:22] <andypugh> if you have the cash, you can play.
[02:07:34] <Valen> seems like a great way of making people in risky situations sleep deprived
[02:07:39] <andypugh> Valen: Well, we actually did 4 4 4 6 6
[02:08:50] <andypugh> You get 12 hrs a day to sleep in. The point is that 6 hrs really is as long as you can usefully work on deck, and sleep-time is less critical than work-time when you are there.
[02:09:10] <Valen> slightly better but still your going to be sleep deprived i think
[02:09:40] <pfred1> man I used to love to stay up for 3 days straight
[02:09:58] <pfred1> stuff starts getting really weird after 72 hours of no sleep
[02:10:22] <Valen> see thats not a good place to be in when if you do the wrong thing your in the drink
[02:12:36] <pfred1> I bet Ernest Shackleton stayed up for more than 12 hours
[02:12:41] <andypugh> As a student I did 72 hrs playing darts (1,000,001 down takes a long time). I wouldnt care to do it again)
[02:13:17] <pfred1> theirs was possibly the most amazing feat of sailing ever
[02:13:33] <pfred1> I think it took them 3 days
[02:13:41] <pfred1> in a rowboat
[02:14:15] <andypugh> And Shackleton is my hero. (well, one of them). I heartily recommend http://www.amazon.co.uk/Shackleton-Roland-Huntford/dp/0349107440/ref=ntt_at_ep_dpt_1
[02:14:17] <pfred1> in the antartic sea
[02:14:43] <pfred1> man if they were off by a half a degree they'd have never been heard of again
[02:14:54] <r00t4rd3d> are you guys sailors?
[02:14:58] <andypugh> Not a rowboat, it was an open sailing lifeboat, and more like 3 weeks.
[02:15:08] <pfred1> it took them 3 weeks?
[02:15:23] <pfred1> I thought they just had to go to that island with the whaling camp on it
[02:15:25] <andypugh> 1000 miles in a 12' boat?
[02:15:48] <pfred1> well they did have to walk across the island too
[02:15:52] <andypugh> Elephant Island to South Georgia.
[02:15:56] <pfred1> which was no easy thing
[02:16:09] <andypugh> And the first overland crossing of SG too.
[02:16:10] <pfred1> it blows my mind that they lived
[02:16:14] <andypugh> Yes, read the book.
[02:16:39] <pfred1> you'd have about the same chance if someone dropped you off o nthe dark side of the Moon
[02:17:16] <andypugh> Nobody died. that's the truly impressive thing. Huntford wrote a hatchet-job of Scott (any fool can die gloriously) but seems to have nothing but respect for Shackleton).
[02:17:47] <pfred1> they say it is the most successful failure of all time
[02:18:10] <andypugh> r00t4rd3d: I was a sailor, until about 2 weeks ago. I may now be an ex-sailor :-)
[02:18:13] <pfred1> how long did the party survive was it years?
[02:18:18] <andypugh> 2 years
[02:18:25] <pfred1> yeah I thought it was more than a year
[02:18:42] <pfred1> how in the heck can you live on antartica for that length of time?
[02:18:44] <andypugh> Possibly 3 if you include the planned parts.
[02:18:53] <Valen> http://en.wikipedia.org/wiki/Ernest_Shackleton#Imperial_Trans-Antarctic_Expedition_1914.E2.80.9317
[02:18:57] <andypugh> by eating seals, mainly
[02:19:03] <pfred1> yeah until the ship got crushed by the ice that was a while wasn't it?
[02:19:26] <pfred1> I heard when he came back they were diving in the water after fish
[02:19:39] <A0Sheds> andypugh, made it back! yay
[02:19:54] <pfred1> lets face it no one wants to die
[02:20:23] <A0Sheds> has it been a year already?
[02:22:09] <andypugh> Eh? No, I only did the Pacific, not the full circumnavigation.

[02:53:30] <Tom_itx> they were all hiding in the closet messin with electronics

[02:54:09] <pfred1> dennis ritchie went to my high school too but long before I did
[02:54:29] <pfred1> I used to see him at the grodery store a lot
[02:54:58] <pfred1> he moved a town away from where I grew up
[02:55:05] <pfred1> well where we grew up
[02:55:23] <Tom_itx> i met carlos santana at the atlanta airport once in passing
[02:55:41] <pfred1> I saw mick jagger on 9th st in NYC
[02:56:07] <pfred1> oh know who I met?
[02:56:11] <pfred1> actually talked to
[02:56:26] <pfred1> janis joplin's manager
[02:56:44] <pfred1> he was pretty kooky
[02:57:01] <pfred1> his big line was I made a million and I spent it too
[02:57:27] <pfred1> he was pretty poor when i met him
[02:57:52] <pfred1> he gave me one of his sound sender gadgets he was making though
[02:58:25] <pfred1> oh i used to see james earl jones walking up woodland ave a lot
[02:58:34] <pfred1> oh here is someone famous i knew
[02:58:59] <pfred1> Peter Dinklage
[02:59:06] <pfred1> I used to pump his gas
[02:59:51] <pfred1> but i knew him before he was famous
[03:00:41] <pfred1> my dad knew some famous people
[03:01:04] <pfred1> I think I met them when I was really young too
[03:01:56] <pfred1> my dad was this guy's best friend http://en.wikipedia.org/wiki/Mark_Donohue
[03:02:09] <pfred1> so of course my dad knew rodger
[03:06:04] <pfred1> someday I'm going to have to go to a race and scare the crap out of rodger
[03:06:23] <pfred1> because i look like the ghost of my dad
[03:10:26] <joe9> alex4nder: i am finding that the taig travel is a lot more than 12", 5.5" and 6".
[03:10:44] <joe9> is travel measured from center to an end or from end to end?
[03:12:23] <pfred1> travel is working area
[03:20:35] <joe9> pfred1: end to end?
[03:21:04] <joe9> pfred1: the reason I ask is the travel for the Z axis is state at 6inches.
[03:21:18] <joe9> but, when I move the Z-axis down by 6 inches, I still do not touch the table.
[03:21:37] <joe9> that makes me think that I do not understand what "travel" defines.
[03:21:47] <pfred1> travel is just the movement
[03:21:52] <Tom_itx> put a tool in the z and see how far you get
[03:21:53] <pfred1> you can raise and lower the head
[03:21:54] <djdelorie> travel == all the way to one end, to all the way to the other end
[03:22:25] <pfred1> the Z on a taig goes 6 inches?
[03:22:35] <pfred1> my RF-32 is only 5
[03:22:37] <joe9> Tom_itx: that is what I am doing. I put a dremel bit in the spindle and notice that it is high up (not even close to the table)
[03:22:43] <joe9> after moving 6 inches down.
[03:23:03] <Tom_itx> consider yourself lucky?
[03:23:05] <joe9> djdelorie: thanks.
[03:23:26] <pfred1> yeah travel and work envelope are different
[03:23:34] <pfred1> like your table is bigger than yoru travel
[03:23:42] <Tom_itx> there is a 'useable cube' though
[03:24:07] <pfred1> travel is usually bigger than what is useful
[03:25:10] <pfred1> I think the longest cut I ever did on my mill is 12 and a half inches but my travel is more than that
[03:26:21] <pfred1> I'm going to say my travel is 23 inches?
[03:26:44] <pfred1> something like that
[03:27:08] <djdelorie> you'd think linuxcnc would have an option for automatically determining the range of travel based on the limit switches...
[03:27:28] <Tom_itx> we cut some wing spars that had to hang out the end of the machining center
[03:27:41] <Tom_itx> over 100" on a 52" travel i think it was
[03:28:01] <Tom_itx> vacuum fixture
[03:28:13] <pfred1> I did all I could think of to get a 12.5 inch cut out of my machine
[03:28:53] <djdelorie> for house construction, it would be useful to have two small cnc machines connected by rails, for milling the end of roof rafters...
[03:29:08] <pfred1> they make big CNC machines for milling houses
[03:29:21] <pfred1> they run on tires
[03:29:21] <r00t4rd3d> whats slightly better then a dremel?
[03:29:29] <Tom_itx> router
[03:29:36] <pfred1> they're like huge gantries
[03:29:54] <pfred1> one guy made a concrete extruder too
[03:29:58] <alex4nder> yah
[03:30:04] <alex4nder> I've seen video, they're great.
[03:30:18] <pfred1> yeah the organic looking stuff italian guy it isn't exactly concrete
[03:31:21] <pfred1> big big big makerbot!
[03:32:10] <djdelorie> r00t2rd3d: I've got an air grinder as my spindle, takes 1/8" bits but less runout. That would be "slightly better" I suppose. Next up would be a trim router, then a regular router...
[03:32:12] <pfred1> ever see teh video of the hexapod CNC robot?
[03:32:26] <alex4nder> yah
[03:32:29] <pfred1> thing walks up on 6 legs then carves a face
[03:32:31] <alex4nder> I want one to do PCB pick-n-place
[03:32:52] <djdelorie> I've seen that on youtube. I've seen LOTS of cnc uses on youtube...
[03:32:54] <pfred1> guy that made it does hollywood special effects
[03:33:13] <pfred1> that thing is pretty nuts

[03:45:03] <joe9> i just measured the amount of travel and I notice that the axis has not travelled 6 inches though linuxcnc says that it has.
[03:45:10] <joe9> It has not even travelled 3 inches.
[03:45:23] <pfred1> then your scale is wrong
[03:45:35] <joe9> oh, ok. thanks. will check on that.
[03:45:51] <pfred1> or you're losing steps?
[03:46:18] <joe9> scale = 400
[03:46:34] <pfred1> stepconf can adjust your scale
[03:46:39] <pfred1> or you can edit the file
[03:46:39] <joe9> I do not think I am losing steps. Is there some method of checking that?
[03:46:47] <pfred1> change yoru scale
[03:46:56] <pfred1> see if how much you move changes
[03:47:14] <joe9> isn't scale calculated by the motor configuration?
[03:47:19] <joe9> s/by/from/
[03:47:21] <pfred1> partly

[04:12:47] <flyback> quick question
[04:12:55] <flyback> ac/dc universal motor
[04:13:14] <flyback> if I remove the brushes, the armature and just leave the coil/stator energized, any danger of overheating?
[04:14:34] <flyback> sorry to bug this channel, but if anyone knows motors....
[04:16:38] <Valen> AC i'd say possibly DC i'd say it'll cook in seconds
[04:16:58] <flyback> just the coil ?
[04:17:23] <pfred1> flyback what are you making a degausser?
[04:17:51] <flyback> i'm converting a burned out hair dryer into a heater blower for drying circuit boards etc, going to put an external blower on the back but I think the motor might be in series with the coils
[04:18:35] <Valen> heater coils?
[04:18:48] <flyback> yes
[04:18:57] <Valen> find out
[04:18:58] -!- tronwizard has quit []
[04:19:03] <pfred1> they're resistive so they should help
[04:20:01] <Valen> motor coils will read as ~0 ohms
[04:21:05] <pfred1> I was messing with an electric iron once and i thought it was shorted out but the thing really was 1.2 ohms
[04:21:05] <flyback> brb
[04:21:14] <flyback> cleaning carbon
[04:21:55] <pfred1> the meter i was checking it with had a lead resistance of .3 I think
[04:22:27] <pfred1> all I know is I pulled that iron all apart the body of it turned out the plug was messed up on it

[04:26:39] <flyback> anyways I just want to reuse the heating part of the dryer
[04:26:45] <flyback> goin gto strap a blower to the back
[04:29:16] * Valen buys flyback a $5 hairdrier
[04:31:26] <flyback> uh I have a new one coming
[04:31:35] <flyback> this is for heat soaking boards to dry them out
[04:31:38] <pfred1> I got a heatgun at a garage sale for $5
[04:32:14] <pfred1> I have an infared heat lamp for curing paint that is handy for stuff like that
[04:32:27] <pfred1> it only makes stuff in front of it hot
[04:32:40] <pfred1> doesn't heat the air
[04:33:33] <pfred1> flyback maybe yo ushould try to score a heat lamp?
[04:34:13] <pfred1> go to a buffet with some welding gloves :)
[04:34:25] <flyback> and no
[04:34:33] <flyback> this was a $40 professional hair dryer
[04:34:38] <flyback> the 6th I have burned out in 6 yrs
[04:34:45] <flyback> they al had 5 yr warrenties too :/
[04:34:54] <flyback> i'm done abusing any so Iam modding the old one
[04:34:56] <pfred1> you sexy beast you!
[04:34:56] <flyback> and heatguns are out
[04:35:00] <flyback> they are too fucking hot
[04:35:17] <Valen> my dad's heatgun goes to 60C
[04:35:20] <flyback> and I don't trust myself not to forget to set it low enough not to burn down thew house or ruin the board
[04:35:32] <Valen> digital temperature guage
[04:35:48] <flyback> I rather use something heat limited to start
[04:36:07] <pfred1> well heat lamps you just put stuff a little further from them
[04:36:20] <pfred1> it is pretty controllable
[04:36:44] <pfred1> I mean heck you can cure paint finishes
[04:36:53] <flyback> I would rather stick to what works
[04:36:54] <flyback> http://imgur.com/a/NmLbE#0
[04:37:04] <Valen> wont trust a heatgun with a temperature read out, trusts jerry rigged hairdryer with no motor
[04:37:40] <flyback> yes
[04:37:41] <flyback> so fuck you
[04:37:44] <flyback> this is what I am doing
[04:37:47] <pfred1> I don't know if I could start a fire with my infared curing lamp
[04:38:18] <pfred1> it is kind of like leaving a newspeper out on the sun is it really going to burst into flame?
[04:38:50] <pfred1> if that actually happened we'd all be in serious trouble
[04:39:35] <pfred1> man it's sunny today I sure hope my asphalt shingles don't go up!
[04:40:39] <Valen> pfred1: my roof is asbestos I'M INVINCIBLE!!!
[04:41:00] <pfred1> Valen everything burns if you get it hot enough
[04:41:16] <Valen> they used to make asbestos table cloths
[04:41:21] <Valen> (aincent grece)
[04:41:29] <Valen> they cleaned them by throwing them into the fire
[04:41:34] <pfred1> I have an asbestos welding blanket
[04:41:51] <Valen> pfred1: I'd be chucking that and getting one that wont kill you ;->
[04:42:08] <pfred1> if i need to I use the thing too because going up in smoke is hazardous to your health like instantly too
[04:42:22] <pfred1> no way it is top notch stuff
[04:42:31] <pfred1> that and asbestos doesn't kill everyone
[04:42:46] <Valen> most of the companies i work for deal with asbestos and its habit of killing people
[04:43:03] * Valen decides to be a dodgy bastard with a website AWESOME!
[04:43:08] <pfred1> I'm pretty sure a lot of the asbestos hysteria was dreamed up by the mafia so the ycould get lucrative remediation contracts
[04:43:27] <Valen> My neighbour died from it
[04:43:45] <pfred1> oh it'll kill some people
[04:43:49] <Valen> and i see a bunch of people every few days that are either dying from it or have relatives who have
[04:43:57] <pfred1> all I'm saying is it doesn't kill everyone
[04:43:57] <Valen> bullets only kill some people too
[04:44:11] -!- mhaberler has quit [Quit: mhaberler]
[04:44:12] <Valen> falling out of aeroplanes isnt 100% fatal either
[04:44:39] <pfred1> well I've been dealing with asbestos all my life and I made it this far
[04:44:57] <Valen> sure, it takes 15-30 years to show
[04:45:08] <pfred1> yup about that long
[04:45:18] <pfred1> on the higher end of the scale
[04:45:24] <Valen> and then you die in 18 months of suffocating slowly
[04:45:28] * pfred1 is 48
[04:46:29] <pfred1> I've ripped up so many asbestos floor tiles and removed asbestos pipe insulation
[04:46:54] <Valen> most of the people dying now are the wives of asbestos workers
[04:47:10] <Valen> because they came home wearing contaminated clothes that the wives washed
[04:47:10] <pfred1> well I can't say I was ever an asbestos worker
[04:47:54] <pfred1> but I don't treat the crap like it is kryptonite
[04:48:25] <pfred1> can't beat asbestos brake pads either
[04:48:49] <Valen> carbon ceramic
[04:49:15] <pfred1> they sound tough on rotors
[04:49:30] <flyback> I guess while people decided to fucking tell me why I don't need "hardware t&L" and how I only need "t-buffer" it's useless to ask
[04:50:00] <Valen> ceramic rotors and carbon-carbon pads i believe is how its done in the performance cars
[04:50:13] <Valen> I use bendix ultra-premium pads and they stop my car just fine ;->

[20:28:07] <ctjctj> asdfasd: That might have been meant for you. I'm easily confused today.
[20:29:32] <ctjctj> I've not tested linuxcncrsh but it says "text-mode interface for commanding linuxcnc over the network" This means that you can tell linuxcnc to load a file from somewhere else. Using standard file sharing methods you can have a shared folder on your PC. Do your CAD/CAM there and the files are just there on your controller.
[20:29:58] <asdfasd> ctjctj: no worries
[20:30:09] -!- rob_h has quit [Quit: Leaving]
[20:30:50] <asdfasd> I never tried that interface
[20:30:59] <asdfasd> but that is a good idea
[20:31:08] <andypugh> asdfasd: Navigating to a remote-mounted folder from inside LinusCNC is non-trivial.
[20:31:28] <andypugh> Or, at least, not as easy as you might hope
[20:32:29] <asdfasd> ok I will leave it for now, thanks for your help
[20:32:48] <andypugh> If you open a remote location in the GUI, then the path to get to it from the LinuxCNC file selection dialog is unobvious
[20:32:49] <ctjctj> andypugh: Depends on NFS or samba but both are pretty easy to set up.

[20:34:57] <andypugh> OK, so I opened Places->Network->Windows Network
[20:35:18] <andypugh> Ah yes, .gvfs, that's it (a hidden directory for extra fun)
[20:35:29] <ctjctj> open up a terminal window
[20:35:45] <ctjctj> cd ~/emc2 (~/linuxcnc)
[20:36:04] <ctjctj> cd nc_files
[20:36:15] <ctjctj> ln -s ~/.gvfs Shared
[20:36:18] <andypugh> You can get there from the LinuxCNC file browser, that's my point. You need to go up a couple of levels and select the "show hidden files" checkbox, then look in .gvfs.
[20:37:03] <ctjctj> I have a "ln -s /media/Transfer Transfer" in my nc_files for my USB stick which is named "Transfer"
[20:37:06] <andypugh> But yes, making a persistent link in nc_files seems like a good idea
[20:37:43] <ctjctj> Because I program tcl/tk but hate it. Only computer language I speak where I *have* to have the manuals in front of me.
[20:38:14] <ctjctj> Having a couple of symlinks there makes a world of difference in how easy it is to find files from around your system.
[20:38:33] <Thetawaves> linuxcnc works flawlessly with nfs
[20:38:46] <Thetawaves> no difference in jitter or anything
[20:38:56] <andypugh> I am sharing a folder on my Mac desktop.
[20:39:07] <asdfasd> .gvfs is empy, what should be there?
[20:39:11] <ctjctj> Even cooler is the fact that if the USB stick is plugged in then the symlink is bad and it doesn't even show up in the list of directories
[20:39:23] <ctjctj> asdfasd: it will be empty until you use "places" to mount the share.
[20:39:48] <andypugh> asdfasd: You need to open the location from Places->Network forst
[20:39:57] <andypugh> (first)
[20:40:33] <ctjctj> Thetawaves: *grins* But setting up nfs is so much harder for most people. And yes, loading files from a network share (NFS, SFTP, WEB) makes no change because linuxcnc loads the entire file and does not touch the file again until you reload or save.
[20:41:32] <ctjctj> but my question remains: How do I get the LinuxCNC components to show up in glade?
[20:41:50] <Thetawaves> setting up NFS was configuring two files that i mostly got from the internet.
[20:41:52] <Thetawaves> so hard.
[20:42:56] <asdfasd> oh yes, once mounted is shown in .gvfs
[20:43:07] <asdfasd> how to make it mount permanently
[20:43:09] <ctjctj> Thetawaves: *nods* sudo mkdir /media/share; sudo vi /etc/fstab; (host:/filesystem /meda/share nfs soft 0
[20:43:50] <ctjctj> Thetawaves: learned that back on SunOS 4.3... Way to long ago (around 1982)
[20:44:05] <Thetawaves> hah
[20:44:20] <Thetawaves> i wanted to run solaris for a time
[20:44:33] <Thetawaves> apparently it has the most solid implementation of nfs4
[20:44:42] <ctjctj> Thetawaves: OpenIndiana is what you want today.
[20:44:45] <Thetawaves> ...not that i've had a single problem with it...
[20:46:15] <andypugh> ctjctj: I confess I have never managed to figure out how to get the GladeVCP LinuxCNC widgets, but then I have not tried too hard.
[20:46:31] <andypugh> Let me see what happens with a brand-new liveCD install on a VM
[20:49:04] <ctjctj> I keep finding myself going in circles. I'm getting ready to cut wood with the output from my cam program but I need to make a fixture and therefore I need to be able to do a rotate as well as an offset which means I want to write a glade interface to make that easy ...
[20:49:17] -!- joe9 has quit [Quit: Lost terminal]
[20:50:44] <andypugh> You don't really need Glade for that, I don't think.
[20:51:03] <andypugh> You can rotate in the MDI with G10 L10 Rnn IIRC
[20:51:36] <ctjctj> Right. But I want to do two touch offs manually to get two points then calculate the actual rotation.
[20:52:01] <andypugh> Ah, right.
[20:52:24] <andypugh> affine transformation matrix ftw
[20:52:25] <ctjctj> so jog to position. push button. Jog to other postion. push button. G10 L10 Rcalculated_value

[20:53:01] <ctjctj> In 3D no less. (Having just been very upset bout Java's AffineTransformations...)
[20:53:56] <djdelorie> better if you could jog to 4 3-D positions and have it calculate the whole 3D rotation for you... ;-)
[20:54:03] <JT-Shop> whew... one more hole to drill in the understraps and they are done
[20:54:41] <ctjctj> djdelorie: How often is that needed?
[20:54:50] <djdelorie> depends on how flat your table is
[20:55:08] <ctjctj> and you only need three points for a plane so you only have to touch off three times.
[20:55:58] <djdelorie> typically, you'd only need two points, assuming your table is flat to Z and you're only concerned about rotation
[20:56:32] -!- joe9 [joe9!~joe9@c-24-99-80-97.hsd1.ga.comcast.net] has joined #linuxcnc
[20:56:35] <ctjctj> djdelorie: my jgro is flat but the damn Z axis is tillted about 5 mils
[20:56:40] <djdelorie> the fourth point tells the difference between a tilted table and a tilted Z axis, or something like that. Non-orthogonal tool motion.
[20:57:00] <ctjctj> ah, good point
[20:57:09] <djdelorie> four points also corrects for a canted Y axis
[20:57:22] <djdelorie> (well, three does if the table is flat etc)
[20:57:58] <andypugh> if you have a non-flat surface then mhaberler came up with a kinematics module to compensate for any warped surface defined by an STL file (which is just an array of points linked into triangles). So, probe the surface, build the STL, load that into the kinematics module and the Z will automatically track the surface. Clever stuff.
[20:58:06] <djdelorie> or, if you're using the cnc machine on a pre-constructed item, like pick-n-place machines, it corrects for a bad tool that made the item previously ;-)
[20:58:34] <djdelorie> andypugh: that might be needed for accurate pcb milling
[20:59:00] <andypugh> I think that was the initial application, but it could also be used to engrave text on complex shapes.
[20:59:08] <andypugh> (for example)
[20:59:25] <djdelorie> although it's probably still better to mill a vacuum holddown flat first ;-)
[20:59:27] <ctjctj> but does it fix the issue of the tool being correctly tangental?
[20:59:29] -!- vladimirek has quit [Remote host closed the connection]
[20:59:32] <djdelorie> or at least easier
[21:00:22] <djdelorie> hmmm... if you have a tilted tool, it's as if you had a four axis machine, right? Then you'd need five points...
[21:00:44] <ctjctj> andypugh: the VM says my issue with glade is 12.04 and 2.6. 10.04 with 2.5 glade does exactly right.
[21:01:09] <mhaberler> which issue with gladevcp?
[21:01:29] <ctjctj> mhaberler: Not gladevcp. glade. I'm writing a gladevcp panal.
[21:01:44] <mhaberler> and what's the issue?
[21:02:31] <ctjctj> Under ubuntu 12.04 with linuxcnc 2.6 installed from buildbot when I run glade the EMC Actions and HAL Python does not show up in glade.
[21:04:43] <JT-Shop> http://imagebin.org/208536

[21:52:50] <JT-Shop> I cheated on the cannon wheels and purchased them and they don't appear to be shrunk on
[21:53:06] <JT-Shop> yes, I made every part except the barrel and the wheels

[21:54:07] <JT-Shop> Jymmm: in the old days they would heat up the tire (the iron ring) and put is over the wheel then cool it off with water and it would shrink to fit the wheel
[21:54:18] <JT-Shop> put it over
[21:54:38] <Jymmm> JT-Shop: Yeah, that's what andy's video showed.
[21:54:40] <ctjctj> the issue today is that it is hard to find a forge that large.

[21:55:02] <Jymmm> I'm sure JT-Shop can make one any size he wanted =)
[21:55:17] <JT-Shop> yea, you do that barefoot
[21:55:24] <Jymmm> or you could jusd a ring of coal
[21:55:47] <Jymmm> a fire ring if you will =)
[21:55:53] -!- sumpfralle has quit [Ping timeout: 245 seconds]
[21:55:54] <JT-Shop> you would be suprised how big a large ring of steel will grow when you warm it up
[21:55:59] <ctjctj> Jymmm: The issue is getting enough O2 into the coal to get the metal red hot so that it expands
[21:56:08] <Loetmichel> sooo, got fan and first of four Switch/indicator/plugpanels mounted... the co-worker for whom i make this CNC could NEVER pay me the work ivested in this beast, if he WOULD pay me anything ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=13098
[21:56:10] <Jymmm> ctjctj: leaf blowers
[21:56:10] <ctjctj> If I remember correctly they normally went red.
[21:56:29] <Jymmm> JT-Shop: did you wake the wood components?
[21:56:32] <Jymmm> make
[21:56:41] <JT-Shop> we used to fit bull gears on mud pumps by heating them up and then slipping them over the hub kinda fast they were about 6' in diameter and about 1' wide
[21:56:49] <ctjctj> Jymmm: Hmmm, I can just see the fire marshal now... "And you were using a leaf blower to blow these coals all over ..."
[21:56:59] <JT-Shop> Jymmm: yes I made everything but the wheels and the barrel
[21:57:10] <Jymmm> JT-Shop: cool, nice job!
[21:57:16] <JT-Shop> thanks

[22:44:41] <skunkworks__> http://groups.yahoo.com/group/mach1mach2cnc/message/134581
[22:55:30] <Loetmichel> skunkworks__: its like a friend said once: "even a company like microsoft with all its Programmers cant continually compete with a open systen, whre thousands of people write code "just for the fun of it"
[23:00:15] <ctjctj> skunkworks__: At one time I worked in a production coding house. We were considered "very fast coders" by the definition of lines of code (not counting comments) produced per day. That number was around 15 lines of code per day per person. Today a single person can produce much more. But there is still a hard limit on just how much code a single person can produce per time period.
[23:00:50] <ctjctj> Open source does a great job of collecting 1000s of small pieces of code and putting them together in ways that no closed shop will ever be able to duplicate.
[23:01:37] <Tom_itx> how do they maintain a sense of direction?
[23:02:11] <ctjctj> Tom_itx: They don't have to have a "Sense of direction". Each person is working on what is important to them.
[23:02:42] <ctjctj> If you want LinuxCNC to be able to "hop" the machine then you can start addition yourself. You can take as long as you want to get there.
[23:02:44] <skunkworks__> that is what happens with linuxcnc (from my observations from the last 5 years or so)
[23:02:49] <Tom_itx> it still has to come back together as a 'package'
[23:03:02] <ctjctj> And when you get there you can ask for it to be added to the package.
[23:03:12] <ctjctj> If people agree it is a good addition, it goes into the package
[23:03:49] <ctjctj> If you look around you'll find dozens of small and large additions/improvements/fixes where one person worked to fix the problem. Some spending vast amounts of time, others hardly any.
[23:04:12] <ctjctj> That code gets back to the package maintainer(s) who make sure it is a good addition and doesn't break anything.
[23:05:21] <ctjctj> Tom_itx: Right now I'm working on a gladevcp panel/tab that will allow me to do manual and later automated multi point probe/touch offs in order to create an affinetransformation for registering a fixture on my table to the x/y axis.
[23:05:33] <skunkworks__> all I can say is that mach4 has been built up so much at this point that I don't know if it can come close to peoples expectations.
[23:05:57] <ctjctj> You might not give a c___ about it. You might never use it. But I'll give it to the project and if they wish to include it or put it somewhere where you and others can get it great.
[23:06:10] <ctjctj> If you don't want that functionality you don't use it.
[23:06:45] <Loetmichel> ctjctj: as in "where the hell is my workpiece?"
[23:07:31] <ctjctj> Loetmichel: as in where in the hell is my work piece and how is it rotated?
[23:07:48] <Loetmichel> ctjctj: i see
[23:08:32] <ctjctj> I've got a few dozen pieces to make that require working on both sides. So I'm going to cut the blanks to size. That requires only touch offs. Then I'm going to cut a fixture to hold those pieces.
[23:08:51] <ctjctj> The first time through that fixture will be perfectly alligned because it will be cut by the machine.
[23:09:19] <ctjctj> At that point I can drop the pieces into the fixture, clamp, route. Unclamp, flip and rotate and route some more.
[23:09:25] <Loetmichel> ctjctj: if you get that running for 5 axis i will applaude loud
[23:10:00] <ctjctj> As long as I don't crash my machine all is good. (but I do crash my machine from time to time)
[23:10:18] -!- koax has quit [Ping timeout: 265 seconds]
[23:10:20] <ctjctj> Loetmichel: It turns into a 3 or 4 point touch off but it can still be done.
[23:10:35] <Loetmichel> i just make temporary fixtures OR make some holes for centering pins in my sacrificial table
[23:10:54] <Loetmichel> hrhr
[23:10:59] <Loetmichel> i crash often
[23:11:08] <skunkworks__> couldn't that all be done with owords?
[23:11:19] <skunkworks__> and g10....rx.xxx
[23:11:20] <ctjctj> *nods* Ok. You've got one centering pin. but did you get that fixture rotated correctly?
[23:11:52] <Loetmichel> but because my stappers have only 1A/phase nothimg more than a broken mill bit
[23:11:55] <Loetmichel> steppers
[23:12:04] <Loetmichel> ctjctj: no, more than one pin
[23:12:09] <Loetmichel> like three
[23:12:18] <Loetmichel> and corresponding holes in the Fixture
[23:12:30] <Loetmichel> or i make the fixture just for one job
[23:12:40] <ctjctj> skunkworks__: The goal is to have a panel which has buttons for touching off (or probing). We read the abs values of two and from that the arc tangent gives us the angle which we feed to G10
[23:12:52] <Loetmichel> like here: http://www.cyrom.org/palbum/main.php?g2_itemId=12578&g2_imageViewsIndex=1
[23:12:58] <skunkworks__> neat!
[23:13:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12581
[23:14:03] <ctjctj> Loetmichel: *nods* Yep. But I'm working on an elcheapo home grown jgro cnc router. I'm lucky I can get 0,0 to be close from run to run. *GRIN*
[23:14:15] <Loetmichel> harhar
[23:14:25] <Loetmichel> my machine is homegrown
[23:14:57] <Loetmichel> and the el cheapo (50ct) ref switches are repeating below 2 steps
[23:15:10] -!- rob_h has quit [Ping timeout: 260 seconds]
[23:15:14] <Loetmichel> that is enoigh accuracy for my taste;-)
[23:16:02] <ctjctj> I think that I need to think about your centering pins. If I put a couple of them in the table then the rotation of the fixture will be fixed only have to recalibrate the router between runs.
[23:16:37] <ctjctj> Loetmichel: Got to get a solder sucker and replace the stupid choice I made on the HobbyCNC chopper driver connector 4 years ago. Then I can have switches and probes.
[23:17:08] <ctjctj> Never thought I'd want those home and limit switches as much as it turns out that I do.
[23:17:21] <Loetmichel> hrhr
[23:17:32] <Loetmichel> i am building a machine for a friend at the moment
[23:17:45] <Loetmichel> from scraps laying around
[23:18:09] <Loetmichel> just have finished the first of four Connector/indicator plates
[23:18:21] <Loetmichel> (two on the front side, two on the back)
[23:18:36] <ctjctj> Sounds like fun. I'm just trying to get enough code running to be able to cut my 2nd machine. 2nd machine has to be stiffer and a bit larger. Must take 26x49 sheets
[23:18:43] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13098
[23:18:47] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13101
[23:19:13] <Loetmichel> y axis ias running and i am getting close to mount the drivers, CPU and PSU inside the chassis
[23:20:08] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13092 <- cpu i "organized" in my company...
[23:20:53] <Loetmichel> Industrial Compiter with P4, 2gb ram, 80GB disk, one sack of IOports ;-)
[23:21:16] <Loetmichel> its the only one that will fit in the base of the router
[23:21:37] <ctjctj> *laughs* I managed to fry one of the driver chips and my parallel port on my second day of cutting. Went to local computer store and asked for a PoS garbage computer. Got it for free. Just slapped a hard drive and it ran LinuxCNC
[23:22:05] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13083 <- underside of the router
[23:22:07] <ctjctj> https://plus.google.com/u/0/110631207635469909107/posts/BQi4kd7PbH8
[23:22:49] <ctjctj> You can see where the router clamp is cracked somewhere in the last 4 moves. Just sad. But it cuts.
[23:23:01] <Loetmichel> left where no holes are cut will be the CPU
[23:23:02] <Loetmichel> i want to make that router "self contained"
[23:23:03] <skunkworks__> http://electronicsam.com/images/KandT/testing/goal3.jpg
[23:23:11] <Loetmichel> just plug in Power, keyboard, mouse and screnn and go for it
[23:23:20] <ctjctj> https://plus.google.com/u/0/110631207635469909107/posts/G2NVWuzsLaQ
[23:23:32] <ctjctj> Loetmichel: Yours is much prettier. I'll get there someday (soon I hope)
[23:24:43] <Loetmichel> ctjctj: its not mine.
[23:24:59] <ctjctj> Ah. Regardless. Looks nice.
[23:25:11] <Loetmichel> i am just building it from scrap a co-worker gave me "PLeas make something working out of it"
[23:25:12] <Loetmichel> ;-)
[23:25:30] <Loetmichel> and that i will do ;)
