[00:20:57] <dmess> WHO know of horizontal/rotary boring mills??
[00:21:30] <dmess> jig boring mills too
[00:21:48] <dmess> i NEED a list..
[00:29:57] <dmess> of mfg's
[00:38:08] <gezr> moore
[00:38:44] <gezr> thats about all you need to look at, they are pretty much the standard bear on jig/boring mills, moore
[00:51:52] <toastydeath> dmess: are you talking odd mfg's
[00:52:05] <toastydeath> or do you need the standard fare like G&L, Lucas, Devleig, etc
[00:52:22] <toastydeath> gezr: Moore never made a boring mill
[00:55:13] <toastydeath> Porteba, Tos, Wotan are a couple more mfg's off the top of my head
[00:55:19] <toastydeath> Titan, I think
[00:55:55] <toastydeath> Mitsubishi made a couple
[00:56:07] <toastydeath> cinci

[15:56:45] <SWPadnos> I wonder when they left
[15:57:29] <als> last night
[15:57:40] <SWPadnos> bummer
[15:58:52] <gezr> als oh, yeah, I did great in school, thanks for asking Ithink
[15:59:00] <als> cool
[16:00:14] <als> now to work on the sugar cube machine? or summer school
[16:01:37] <gezr> summer school starts morrow, been working on a bike, ill p ost the pics, sorry about messytyping, got gloves on, painting
[16:02:09] <als> I have no excuse!
[16:02:13] <gezr> http://picasaweb.google.com/dagezar/K100Restoration
[16:02:28] <gezr> thats pretty much up to date with things
[16:02:41] <gezr> getting parts in on wensday to allow me to finish putting the engine together
[16:03:29] <gezr> im still not happy withthe exhaust cover paint job, its a ceramic paint in a gloss, and it reallyhard to get that gloss look withoutthe beads showing up
[16:04:09] <gezr> i have afew funny spot on it, so i guess ill take the gloves off and be happy
[16:04:14] <gezr> I alreadystripped it once
[16:04:48] <gezr> and talked some about the sugar cube mill yesterday, I think I can do it here at home, but ill have to break the pieces up into smaller bits, no big deal
[16:05:20] <gezr> so Ill have x and y machined as seperate parts, then pin/screw them together
[16:05:58] <gezr> was trying to keep the base one solid piece but if I break it up, Ill be able to use a box style way, with T type hold
[16:06:25] <gezr> and im going to shoot for .001-.002 play between surfaces, and run them on a film of grease
[16:06:42] <gezr> or oil, grease may be too thick
[16:06:57] <gezr> ./end wall of text
[16:09:26] <gezr> oh, I had to toss out ubuntu, I dont like it at all, so ill be needing to do a compile after all
[16:09:59] <SWPadnos> did yo udecide you don't like Ubuntu, or that you don't like Gnome?
[16:11:48] <gezr> its Ubuntu, Ive been a debian user for a long time, and I didnt like the way in which ubuntu had some things limited
[16:12:01] <SWPadnos> oh, interesting
[16:12:13] <gezr> I tired to merge it over to debian sid, and ended up with breaking some things
[16:12:26] <SWPadnos> well, that's bound to happen ;)
[16:12:36] <gezr> there are some packages and placements I didnt like
[16:12:55] <cradek> BigJohnT: the probe I have IS a MP700
[16:13:43] <gezr> ubuntu is great, dont mistake that, I just do a lot more with my linux boxes,
[16:17:01] <SWPadnos> oh - no worries. I'm just curious
[16:17:30] <gezr> yar
[16:18:01] <gezr> so I have to relearn cvs, all the good stuff,
[16:18:14] <gezr> then I can get to work on fixing things :)
[16:18:29] <skunkworks> Guest404: hello
[16:26:14] <micges> logger_emc: bookmark
[16:26:14] <micges> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-05-30.txt
[16:28:20] <micges> jepler: my module is not simple python module
[16:28:35] <micges> it is simmilar to yours emcmodule.cc file
[16:29:14] <micges> I don't wan't to modify yours but test my own in source tree of emc\
[16:38:43] <jepler> micges: oh, I must have misunderstood what you said.
[16:39:55] <jepler> micges: refer to src/emc/usr_intf/axis/Submakefile to see how other Python modules are linked. Or, consider adding support for the additional nml messages inside extensions/emcmodule.cc rather than in a new module
[16:40:56] <jepler> roughly: add your source file(s) to PYSRCS (line 6 in my copy), then add a new rule similar to $(EMCMODULE) (line 22 in my copy), and add that to PYTARGETS (line 39 in my copy).
[16:44:08] <micges> jepler: this was useful thanks
[16:53:33] <cradek> BigJohnT: I also emailed renishaw for information about the receiver options. Looks like I need either "OMI" or "OMM"+"MI12" to go with my MP700
[16:53:57] <cradek> BigJohnT: now I will start preparing myself so I remember to continue breathing when I see their prices
[16:55:03] <BigJohnT> LOL
[16:55:26] <cradek> you know it's bad news when they hide the prices so you have to ask
[16:55:41] <SWPadnos> it's a health risk to publish them
[16:55:46] <BigJohnT> Yea, I hate that with a passion
[16:56:04] <cradek> me too. I just go on to another company if at all possible.
[16:56:14] <gezr> so ive got my aluminum blocks out, and im looking at machine size stuff atm
[16:56:23] <BigJohnT> or hot wire it :)
[16:56:52] <cradek> I have thought about that, but I would hate to take it apart
[16:57:18] <BigJohnT> helicopter john took his apart!
[16:57:40] <BigJohnT> it cost him $980 to get it put back together
[16:57:50] <cradek> ha
[16:57:56] <cradek> but he didn't MEAN to...
[16:58:03] <cradek> what did he do? just smash it into something?
[16:58:36] <SWPadnos> "Note how my Haas VF3 effortlessly attempts to mill steel with my Renishaw wireless probe"
[16:59:07] <cradek> I wonder if dial indicators or probes cut better
[16:59:27] <gezr> how fast we going to spin it?
[16:59:36] <SWPadnos> I wonder if anyone wants to sacrifice their indicators and probes so we can find out
[16:59:59] <cradek> I always put the machine in neutral before I insert my (very nice) DTI
[17:00:06] <SWPadnos> all in the name of science, of coure
[17:00:13] <gezr> so im looking at my aluminum, and im thinking my machine is going to look really ugly
[17:00:13] <cradek> because who knows what brain malfunction I might have
[17:00:39] <SWPadnos> gezr, that's what anodizing is for
[17:00:59] <cradek> we recently powder coated some aluminum. it looks very nice.
[17:01:15] <cradek> of course anodizing is better (harder) but if it's for looks, this is much easier
[17:01:21] <SWPadnos> dimensional stability is a bit better with anodizing
[17:01:28] <gezr> doesnt aluminum aneal at 400deg?
[17:01:39] <cradek> I don't know
[17:02:01] <cradek> we did bake it at around 400? 450?
[17:02:34] <gezr> i know you can heat treat it in a oven
[17:03:04] <SWPadnos> 7075 is 775 degrees
[17:03:22] <SWPadnos> http://www.suppliersonline.com/propertypages/7075.asp
[17:03:29] <SWPadnos> there are probably other alloys listed there
[17:06:12] <gezr> BigJohnT: you there?
[17:06:22] <BigJohnT> yes
[17:06:32] <gezr> so your really good with solid works?
[17:07:11] <BigJohnT> very good!
[17:07:33] <gezr> hmm
[17:07:43] <gezr> Im having trouble with my machine design here
[17:08:01] <gezr> well, not really, what Im having trouble with, is I dont want to cut my aluminum
[17:08:15] <gezr> dont really want to make a mistake
[17:08:42] <gezr> I guess how it looks shouldnt be something for me to worry about?
[17:09:07] <SWPadnos> plan on making a mistake or two - it's more fun :)
[17:09:09] <BigJohnT> mistakes are called experiance
[17:09:20] <SWPadnos> and the amount of stock you're looking at is pretty inexpensive
[17:09:20] <cradek> if you make no mistakes, you aren't learning anything
[17:09:27] <gezr> im taking the nasa approach to this
[17:09:28] <BigJohnT> or doing anything
[17:09:34] <gezr> would rather land then bounce
[17:09:58] <gezr> I mean, ive got a nice 1x3x8 inch piece of aluminum
[17:10:11] <BigJohnT> what grade
[17:10:18] <gezr> 3x3 is going to take up the Y axis and the wings to mount it to the X
[17:10:21] <SWPadnos> NASA breaks a lot of stuff before they build anything useful - it's intentional
[17:10:25] <gezr> T6061
[17:10:43] <BigJohnT> ok, soft gooey stuff
[17:11:26] <gezr> its not the material im worried about, its like this, the motors, are 1/3 the size of the way surfaces
[17:11:54] <gezr> I guess I should just get to it
[17:12:09] <gezr> leave it bulky and nasty
[17:13:54] <gezr> go go gadget haxsaw. afk
[17:19:51] <BigJohnT> go get em gezr
[17:21:57] <gezr> omg not owning a saw sucks
[17:23:37] <BigJohnT> we cut 6061 with the table saw if < 0.500" thick
[17:37:29] <gezr> plaining now
[17:38:25] <awallin> was there a change to G64 that now also allows belnding of arc moves? Will that be in 2.2 anytime soon? or just for 2.3?
[17:39:19] <rayh> I favor a getting it into 2.2.next.
[17:39:28] <rayh> So we have it at Fest.
[17:40:25] <awallin> ok. I have a machine and G-code where it could make a difference, so would like to test it when it's available in a release (maybe not wise to run a machine with TRUNK ?)
[17:41:20] <rayh> I dont see any real problems with running trunk but then I compile all the time.
[17:41:38] <rayh> And expect to find a few issues.
[17:42:06] <rayh> You might set up both on the machine.
[17:43:04] <alex_joni> I'm not sure it qualifies as a bug-fix though
[17:44:20] <gezr> shapping has to be one of the most fun metal cutting way
[17:45:57] <BigJohnT> awallin: I'm running my plasma on pre 2.3 with the G64
[17:46:40] <BigJohnT> alex_joni: it bugged me!
[17:47:31] <SWPadnos> it's not finished yet anyway, unless someone added the G18/G19 code
[18:09:21] <pjm_> evening all, btw does anyone know if the HAL can support IO on the cts/rts/dsr/dtr pins on a serial interface?
[18:10:58] <SWPadnos> yes
[18:11:03] <SWPadnos> it's called "serport"
[18:11:11] <SWPadnos> (the driver that does that)
[18:11:58] <pjm_> ahh ok cool, i just had a quick scan through the integrators guide but must have missed that, i'll do a quick search, thanks
[18:17:50] <SWPadnos> hmmm. maybe it's called hal_serport?? :)
[18:18:29] <pjm_> ah yes i've found the info on the wiki, just what i was looking for, thanks for the pointer
[18:18:32] <SWPadnos> sure
[18:18:39] <SWPadnos> also man serport should tell you something
[18:18:53] <pjm_> ok great, i'll give that a try
[18:21:43] <gezr> BigJohnT: if your still there, ill be uploading a photo really shortly
[18:24:19] <BigJohnT> ok
[18:24:32] <jepler> awallin: the change to arcs in tolerance mode will not go in 2.2; it's not a bugfix.
[18:24:45] <jepler> awallin: it'll be in 2.3 unless problems turn up and taking it out turns out to be easier than fixing it.
[18:24:59] <gezr> BigJohnT: whats your email?
[18:25:31] <cradek> arcs are already blended. this change only helps skip through tiny useless arcs.
[18:25:36] <BigJohnT> jet1024 at semo dot net
[18:25:55] <BigJohnT> and does that well cradek
[18:26:02] <cradek> great
[18:27:47] <gezr> sent
[18:40:31] <BigJohnT> I see you like hershey kissies
[18:41:32] <gezr> wife left me a few out to enjoy today :)
[18:41:49] <gezr> does that give you a better look at it?
[18:42:00] <gezr> the main block with y on it, is 3x3
[18:42:09] <gezr> the other blocks are just fillers
[18:43:54] <BigJohnT> yea, I kinda though made up of smaller blocks
[18:44:12] <BigJohnT> I have something at home that I can share this evening
[18:44:20] <gezr> that looks a bit better then the solid y and x piece, its going to be a bit longer then I wanted but should be cool
[18:45:00] <gezr> if you do it in 3d for me (which im hopping for, make the channel for the screw .75" deep, screw center is about .5 down
[18:45:56] <gezr> ill probably make the bottom of the channel rounded or have a \_/ type shape, not sure yet
[18:46:12] <gezr> \__/ I mean
[18:49:32] <BigJohnT> what I have is just the generic shape/idea you would have to adjust it to the size you need
[18:50:44] <gezr> sure
[18:54:42] <gezr> im thinking for limit switches, just drilling holes into the sides, and putting like a reed set in there
[19:37:36] <alex_joni> good night all
[20:41:47] <tom1> SWPadnos: ever used ferrites on flatbands for noise? loop thru or clamp on or is it as useful as swinging a dead cat overhread?
[21:01:22] <K`zan_emc> what is the program one runs to find out how much real time delay one has. Mine is horrific and I never corrected for it, might b e part of the problem?!?
[21:02:42] <skunkworks> run latency-test from terminal
[21:03:32] <tom1> & read on the wiki to evaluate the results
[21:03:34] <K`zan_emc> skunkworks: Thanks. Something weird about this machine that occasionally makes for a HORRID delay. Gonna see about getting the numbers (as absurd as they are) and see if that helps any,
[21:03:48] <K`zan_emc> Looked for it on the wiki, that is why I asked here :).
[21:05:09] <tom1> search latency? i get http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test
[21:05:33] <tom1> np. can be confuzin
[21:07:03] <K`zan_emc> http://linuxcnc.org/docview/html/ - if it is there I'm not having any luck :-(. No idea which of the two numbers (Max Jitter) servo thread or base thread is the one that is important (and if one isn't, why is it there?!?)
[21:08:16] <tom1> try http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#RTAI_Latency_test
[21:08:34] <tom1> " There should be no overruns, and "lat max" should probably be below your BASE_PERIOD setting. "
[21:09:18] <tom1> oh, this is the 2 differnt test scenario, i got caught in that myself....
[21:09:37] <tom1> at the last posted url, use the last posted evaluation
[21:09:57] <tom1> and use the test technique at the last posted url
[21:11:35] <K`zan_emc> Interesting (and frustrating:), what I get is a window with those things updating in it - nothing on the terminal useful.
[21:12:15] <tom1> you used http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test instead of http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#RTAI_Latency_test, and yes, you get a pop up
[21:12:23] <K`zan_emc> Also interesting, I have onboard video...
[21:12:51] <tom1> some people get away with it, ( sometimes you feel like a nut ....)
[21:14:42] <K`zan_emc> It sure seems that this celeron 2G is klunky as hell, my 2.2G AMD runs rings around it.
[21:15:44] <K`zan_emc> Was under the impression that the celeron was pretty quick. May be the onboard video that is causing the problem too. Need to track down a PCI card for it - no AGP on this thing.
[21:16:05] <K`zan_emc> SO many potential areas for problems.
[21:16:15] <cradek> celerons have tiny cache so their performance is terrible even if they have a high clock rate
[21:16:52] <K`zan_emc> Ah, no wonder it was a freebie. Might be better off with that old Thunderbird 1100 in the closet?
[21:17:11] <cradek> I don't know what a thunderbird is
[21:17:47] <K`zan_emc> Old AMD, preceeded the Athlon or maybe it is the earliest of the Athlons - 5+ year old machine...
[21:17:59] <K`zan_emc> 1.1GHz
[21:18:16] <K`zan_emc> And it takes AGP cards.
[21:18:22] <cradek> don't know, sorry, but couldn't hurt to try it
[21:18:56] <K`zan_emc> Might well, that message I get about extreme delays rather frequently I don't like.
[21:19:21] <K`zan_emc> Not sure that is the reason that my moves don't move all the way, probably not, but...
[21:19:52] <cradek> realtime errors WILL cause steppers to stall
[21:21:00] <K`zan_emc> Took me an hour or so beating hell out of the box to get that huge jitter number before. Will putz and let it run.
[21:21:20] <cradek> I did not see your numbers
[21:21:47] <K`zan_emc> I forget what they were but the impression was it was pretty awful.
[21:22:10] <K`zan_emc> I never put anything in stepconf for it. Sorta forgot about it with all else that was going on.
[21:27:07] <K`zan_emc> servo: 38357; base 47929
[21:27:20] <K`zan_emc> wb jmkasunich
[21:27:41] <jmkasunich> thank you
[21:27:51] <jmkasunich> civilization is restored!
[21:28:11] <cradek> did you have weather?
[21:28:15] <BigJohnT> gezr: http://imagebin.ca/view/ectCIdrY.html
[21:30:15] <jmkasunich> I don't think it was weather - it seems like it is gonna storm this evening, but it hasn't yet
[21:30:23] <jmkasunich> power just went out for no apparent reason
[21:30:34] <jmkasunich> (at work and at home)
[21:30:47] <cradek> huh
[21:31:24] <K`zan_emc> apt-get source rtai-3.3 ... E: Unable to find a source package for rtai-3.3. Sigh, LOL.
[21:32:25] <cradek> that's not the right name
[21:32:31] <cradek> rtai-modules-something-or-other
[21:32:37] <K`zan_emc> Sigh, screw it.
[21:32:39] <cradek> look at your installed packages
[21:32:59] <K`zan_emc> This damn intel mb goes directly in the shitter. Tired of screwing with it.
[21:33:07] <gezr> BigJohnT: hmm, its oh, it may still be uploading?
[21:33:59] <gezr> its not showing up for whatever reason, maybe the img type?
[21:34:28] <BigJohnT> gezr: does the 3-d cad look close to your picture?
[21:34:38] <gezr> Its not loading for some reason
[21:34:45] <BigJohnT> might be
[21:34:51] <BigJohnT> let me check it
[21:35:15] <BigJohnT> can you see yours http://imagebin.ca/view/e0gNvkt5.html
[21:35:31] <gezr> yeah
[21:35:47] <gezr> tif v jpg
[21:37:42] <cradek> I can see a little mill in there if I look at it just right
[21:37:50] <cradek> there's some extra aluminum in the way though
[21:38:11] <jmkasunich> I think you need a mill to mill the mill out of those blocks
[21:38:17] <cradek> yes
[21:38:32] <cradek> or a hacksaw and file, and a lot of patience
[21:41:28] <BigJohnT> let me save it as a jpg and try again
[21:41:37] <BigJohnT> gingerly
[21:49:07] <BigJohnT> gezr: http://imagebin.ca/view/D1sZ6S7.html
[21:51:04] <BigJohnT> * BigJohnT is going out to the shop
[22:07:48] <dmess> hi all
[22:18:59] <BigJohnT> gezr: did you see the second one
[22:19:01] <gezr> BigJohnT: that looks great
[22:19:02] <gezr> yes
[22:19:10] <BigJohnT> good
[22:19:23] <gezr> thank you, I just got back to the keyboard, filling my head with ideas now :)
[22:19:41] <BigJohnT> there you go then you got the ball run with it
[22:20:09] <BigJohnT> a picture makes it easier to understand...
[22:20:25] <BigJohnT> * BigJohnT goes back out to the shop
