[02:08:57] <danimal_garage> i tried the cosmos screen saver again and it threw another realtime delay error
[02:09:04] <danimal_garage> seems to be related to that
[02:09:30] <danimal_garage> doesnt do it with a blank screen saver

[02:22:34] <seb_kuzminsky> danimal_garage: there's lots of info on the wiki about fixing latency issues
[02:26:34] <danimal_garage> seb_kuzminsky, i've read quite a bit on the subject, noone seems to have issues with this mobo but me
[02:26:46] <danimal_garage> it's a d510mo
[02:30:55] <seb_kuzminsky> huh
[02:30:59] <seb_kuzminsky> using onboard video?
[02:36:59] <danimal_garage> yes
[02:37:26] <danimal_garage> weird, huh?

[02:38:31] <danimal_garage> i had to do nomodeset in grub in order for it not to restart in the middle of the night or throw edid errors
[02:38:59] <danimal_garage> also, it seems that ubuntu is under the impression that it's a laptop
[02:39:47] <danimal_garage> it has settings in power management for it as well as it listing laptop as a display
[02:43:43] <danimal_garage> considering going back to 8.04 :/

[03:48:00] <atom1> well, i can't get it to run
[04:01:11] <pcw_home> what does it do?
[04:02:14] <atom1> nothing
[04:02:18] <atom1> it doesn't launch
[04:02:29] <atom1> it did it on this machine as well as the itx
[04:02:39] <atom1> until i installed it
[04:02:47] <atom1> then it worked
[04:03:01] <pcw_home> what does it do if launched from a terminal?
[04:03:26] <atom1> i can't try it now, i'm installing
[04:03:30] <atom1> :)
[04:04:55] <atom1> i'm gonna try it on this board but i don't think i have enough ram installed: http://tom-itx.dyndns.org:81/~webpage/itx/EPIA-MII-45.jpg
[04:05:05] <atom1> and it may be too slow
[04:05:52] <pcw_home> OK I dont think Ive tried running the latency test from the CD, I expect that its supposed to work so maybe some setup or path problem
[04:06:17] <atom1> well, i'll install it and try it then
[04:09:42] <atom1> are there minimum ram requirements for emc?
[04:09:54] <atom1> or maybe i should ask what they are
[04:14:27] <pcw_home> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Hardware_Requirements
[04:16:21] <atom1> i'm thinking it will be marginal if it works
[04:17:28] <danimal_garage> these flavored snyder's of hanover sourdough pretzel pieces are extremely addicting
[04:18:16] <danimal_garage> just thought i'd throw that out there

[07:14:28] <Connor> Hey Guys, I've seen some conversions for machines were they put Gas springs on the Z-Axis.. Why do they that?
[07:14:52] <Jymmm> To counter balance it
[07:14:54] <anonimasu> to balance it out so it'll be easier to move up
[07:16:13] <Connor> I knew that, I was just trying to figure out if it was really needed, or what..
[07:17:02] <anonimasu> depends on how heavy your z axis is
[07:17:46] <Connor> I guess so.
[07:18:07] <Jymmm> It's like an elevator, the cab needs to be counter-balanced to go up/down
[07:18:47] <Connor> I still haven't found a replacement coupler yet.. kinda getting aggravated. ..
[07:19:00] <Jymmm> Why make a motor work more than it needs to
[07:19:07] <anonimasu> Connor: what kind of coupler?
[07:19:17] <Connor> I guess I could see it if you had a Z-axis with a smaller motor, or with a screw that didn't have fine enough threads..
[07:19:42] <Connor> Well.. I had Alum Helix cheapie from China that broke..
[07:19:47] <Connor> 8mm to 10mm
[07:19:51] <Connor> 30mm in length.
[07:20:19] <Connor> I need one that can handle 2.5N.M torque..
[07:20:30] <Connor> and don't want to pay a arm and a leg for it..
[07:20:44] <anonimasu> how much is a arm and a leg?
[07:21:11] <Connor> I could see paying 25-30 for one.. but double that is a bit much..
[07:21:17] <anonimasu> google for rotex
[07:21:21] <Connor> which is what I'm finding.
[07:21:41] <anonimasu> 2.5Nm isnt reallly so much
[07:22:00] <Connor> No, but a beam or helix in stainless pushes the cost up.
[07:22:11] <anonimasu> why does it need to be stainless?
[07:22:36] <Connor> flex + alum = stress factures.
[07:22:50] <Connor> they break, this is my 2nd broken alum one.
[07:23:13] <anonimasu> yeah, but are you sure that it's not just the sizing of it that's worng
[07:23:30] <Connor> I'm not sure of anything at this point.
[07:23:37] <anonimasu> how long did it take for them to break?
[07:24:00] <Connor> Well, truth be told, both broke do to my stupidity by letting it crash.
[07:24:05] <anonimasu> heh
[07:24:39] <Connor> I forget the Y axis is a bit slower (and has more torque) than the X, and thus, the stepper doesn't stall out as easily.
[07:25:07] <Connor> I was working in installing my limit switches... and had a not so nice malfunction
[07:25:11] <anonimasu> you know, they appear after a 10^12 cycles or something
[07:25:16] <anonimasu> the stress fractures
[07:25:55] <Connor> okay, finding all kinds of mention of rotex, but not a true online store...
[07:27:02] <anonimasu> actually 10^5 cycles tho it all depends on your load
[07:27:05] <Connor> oh.. and freaking alibaba
[07:29:37] <Connor> Oh, and I wanted clampping style vs set screws.
[07:30:02] <anonimasu> you can forget low price now
[07:30:11] <Connor> Yea.
[07:31:08] <Connor> Oldham's look kinda neat..
[07:31:08] <anonimasu> btw, from my point of view the coupler saved your machine
[07:31:17] -!- The_Ball has quit [Write error: Broken pipe]
[07:31:32] <anonimasu> they only work for small radial mismatch

[07:59:33] <mrsunshine_> Connor, i have a 0.40kw spindle motor and the whole spindle thing hanging in my motor and it moves fine, tho its not very strong upwards :P
[07:59:45] -!- The_Ball [The_Ball!~The_Ball@123-2-12-83.static.dsl.dodo.com.au] has joined #emc
[08:00:23] <Connor> Cool.
[08:00:48] <mrsunshine_> its on a X1 using 1.85nm stepper motors, with beasts of drivers :P
[08:00:56] <mrsunshine_> with old drivers, sure it could move it but only very slowly :P
[08:01:14] <mrsunshine_> but im going to get Z+ helper
[08:01:22] <Connor> 1.85.. That's what around 250oz or so ?
[08:01:30] <mrsunshine_> dont know :P
[08:01:37] <mrsunshine_> do not deal in US measurements :P
[08:02:07] <Connor> 1.85 newton meter = 261.982 074 72 ounce inch
[08:02:12] <Connor> Ha! Not a bad guess!
[08:02:50] <mrsunshine_> thinking of getting biggers mtoors tho as my drivers can take 90V 7.8A ...
[08:02:52] <mrsunshine_> so why not :P
[08:03:21] <mrsunshine_> something like 6nm :P
[08:03:35] <Connor> I'm using 354oz-in on my machine.. (that's around 2.499nm)
[08:03:55] <mrsunshine_> or no, 3nm should do as its still in the nema23 frame
[08:04:06] <Connor> for my x and y, but, it's a router, not a mill.. and the Z uses a 287oz-in
[08:05:00] <Connor> 420oz-in (or around) is a common double/tripple stack nema23
[08:05:35] <mrsunshine_> http://img513.imageshack.us/img513/2697/17500110150101318668648.jpg <-- all of that is hanging in that motor only moving up and down
[08:05:41] <Connor> I don't think I'm getting full torque out of mine because of my controller.. again, cheap chines crap
[08:06:01] <Connor> lovejoy coupler.
[08:06:11] <Connor> nice., TPI of your Z lead screw ?
[08:06:16] <mrsunshine_> Connor, ye, i bought expensive ones so that i would have upgradability and quality stuffs =)
[08:06:29] <mrsunshine_> Connor, its 1.5/mm :P
[08:06:40] <mrsunshine_> inches you get to calculate :P
[08:07:24] <Connor> about a 1/2"
[08:07:25] <mrsunshine_> tho cheap chinese crap mill
[08:07:36] <mrsunshine_> Connor, 1.5 not 15 :P
[08:07:46] <mrsunshine_> or whatever
[08:07:48] <Connor> 1.5 mm right ?
[08:07:57] <Connor> sorry. dropped a . off.
[08:07:57] <Jymmm> .15
[08:08:04] <mrsunshine_> well hmm :P
[08:08:06] <Connor> .059"
[08:08:09] <anonimasu> mrsunshine_: isnt that pretty far from when you were building the stepper drive's :)
[08:08:11] <Jymmm> 9.50
[08:08:14] <mrsunshine_> its 1.5 thread per mm of travel :P
[08:08:22] * anonimasu remembers
[08:08:22] <mrsunshine_> anonimasu, heh :P
[08:08:30] <mrsunshine_> that stepper driver worked =)
[08:08:35] <mrsunshine_> tho only had half step
[08:08:37] <Jymmm> 1/SQRT(5)
[08:09:00] <mrsunshine_> http://www.youtube.com/watch?v=F0TjS0N0rwc
[08:09:10] <Connor> my X and Y are 10mm per turn, and the Z is 5mm per turn.
[08:09:18] <Jymmm> Err my bad... 1+ SQRT(5) /2
[08:09:24] <mrsunshine_> Connor, ballscrews?
[08:09:29] <Connor> Yea
[08:09:34] <Jymmm> screwballs!
[08:09:36] <mrsunshine_> mine is just threaded rods realy :P
[08:09:43] <mrsunshine_> tho the table screws are acme
[08:09:51] <Connor> http://www.ivdc.com/cnc/
[08:10:07] <mrsunshine_> the mills column is borked tho, its thinner in the upper parts then the lower parts, making it impossible to get the gibs tight and good :/
[08:11:00] <Jymmm> mrsunshine_: angle grinder
[08:11:11] <mrsunshine_> Jymmm, ough :P
[08:11:21] <Jymmm> mrsunshine_: plasma cutter?
[08:11:22] <mrsunshine_> Jymmm, to cut it into pieces and recast it or what? :P
[08:11:31] <mrsunshine_> Jymmm, what are you talking about? :P
[08:11:36] <Jymmm> mrsunshine_: to "shave" off the excess
[08:11:49] <mrsunshine_> Jymmm, well i wont do it with an angle grinder atleast :P
[08:11:50] <Jymmm> mrsunshine_: the golden ratio
[08:11:51] <mrsunshine_> nor plasma
[08:11:55] <Jymmm> wuss
[08:12:13] <mrsunshine_> sounds about right :P
[08:13:14] <Jymmm> Did you know.... That the Golden Ratio is related to the Fibonacci numbers
[08:13:24] <anonimasu> yes :)
[08:13:34] <Connor> dang ebay china seller doesn't list the bend radius for their drag chain... Ugg..
[08:14:02] <Jymmm> I can only get to 15 digits then the dumb computer poops out
[08:15:22] <Jymmm> Anyone have a spare Super Computer I can borrow for 10 minutes?
[08:19:15] <Jymmm> anonimasu: Hey did you notice any other patterns in the fibinacci umbers?
[08:19:40] <anonimasu> nope just remember it from the math classes in basic school
[08:20:47] <Jymmm> anonimasu: I found a pattern (ODD, EVEN, EVEN)
[08:21:18] <Jymmm> err.. EVEN, ODD, ODD I mean
[08:21:40] <Jymmm> 0,1,2,3,5,8,13,21,34...
[08:22:17] * anonimasu nods
[08:22:32] <anonimasu> sounds like something you could prove with induction
[08:22:38] <Jymmm> ?
[08:22:50] <anonimasu> that it's valid for all numbers
[08:22:58] <Jymmm> oh.
[08:23:21] <Jymmm> I have a unroven theory about numbers
[08:23:23] <anonimasu> http://en.wikipedia.org/wiki/Mathematical_induction
[08:23:26] <Jymmm> unproven
[08:24:14] <Jymmm> But as I learn more and more, it seems there is some truth in it.
[08:25:23] <psha> Jymmm: it's obvious that this pattern is recursive
[08:25:37] <psha> fib(n+2) == fib(n+1) + fib(n)
[08:25:49] <psha> so if n+1 is even and n is even then n+2 is odd
[08:26:00] <psha> and so on
[08:26:11] <psha> n+3 is even since n+1 is even and n+2 is odd
[08:26:19] <psha> same for n+4
[08:26:22] <psha> and then it loops
[08:26:27] <Jymmm> But dont look at from a mathematical standpoint and what do you see?
[08:26:43] <psha> Jymmm: i can not look from non-math point ;)
[08:26:51] <Jymmm> oh well
[08:26:52] <psha> i'm mathematician :)
[08:27:00] <psha> 5 years of math in university :)
[08:27:17] <Jymmm> and you STILL haven't learned a thing, tisk tisk
[08:27:35] <Jymmm> ;)
[08:28:21] <Jymmm> Eyes ars kollage edjoomakated
[08:29:11] <psha> i've studied math, not english dialects :-P
[08:29:14] <anonimasu> 6hehe
[08:29:28] <Jymmm> Hard to explain, but I go with we use numbers to explain things, but yet the real understnading is the shape
[08:29:46] <anonimasu> cant quite agree on that
[08:30:12] <Jymmm> Well, Circle is explained as 3.14, conical shape is explained as 1.618, etc
[08:30:19] <psha> Jymmm: use numbers to explain => develop some formal models in numbers => project them back to real world
[08:30:33] <Jymmm> psha: lather rinse repeat

[08:30:50] <anonimasu> Jymmm: actually pi is a integral...
[08:31:06] <Jymmm> anonimasu: what number is in ALL circles?
[08:31:20] <psha> anonimasu: in war time pi may be as large as 4!
[08:31:49] <anonimasu> pi ofcourse
[08:31:55] <Jymmm> which is?
[08:31:57] <psha> and right angle up to 100 degrees
[08:32:12] <anonimasu> I get your point
[08:32:14] <anonimasu> :)
[08:32:15] <Jymmm> =)
[08:32:29] <anonimasu> no the one jymm is trying to make :├p
[08:32:41] <psha> Jymmm: really pi is not 'number of all circles'
[08:32:42] <anonimasu> err not..
[08:32:48] <psha> what's number of geometrical shape?!
[08:33:11] <psha> i'd think 'number of all circles is (x - a) ^ 2 + (y - b) ^ 2 = r ^ 2
[08:33:18] <Jymmm> psha: free your deviant mathematical mind!
[08:33:42] <Jymmm> psha: but that's NOT a number, that's a formula
[08:33:44] <psha> Jymmm: too late :( once it's eaten it not possible to restore it to previous shape

[08:34:45] <anonimasu> I think there's no escape from math :)
[08:34:47] <Jymmm> ;)
[08:35:26] <Jymmm> anonimasu: I think we use math as a way to describer things, like we might use ABC blocks to teach a kid the alphabet
[08:36:12] <anonimasu> it's like once you study about stress and straing and stuff you will always think twice when you get on airplanes :p
[08:37:25] <Jymmm> Well, there's a therory that if you can understnand all the factorial number patterns the wolrd as we know it would come to an end.
[08:39:29] <psha> Jymmm: funny thing is that on last year in university (and in post-grad) there is course of phylosophy of math. it's given such late because younger students may be affected by news that nothing in math is really stable and trusted :)
[08:39:55] <Jymmm> heh
[08:40:40] <psha> and that's really problem - correct definition of numbers is braindamaging...
[08:41:05] <Jymmm> I think it's really shapes, not numbers
[08:41:27] <psha> shapes, numbers... every trivial term becomes something under question///
[08:41:51] <anonimasu> psha: well, that's why the mathematicians are so stuck up on the definition of proof and axioms
[08:41:51] <Jymmm> no, dont think like a mathemation you human slide rule!
[08:42:20] <Jymmm> psha: shapes ARE the proof
[08:42:35] <Jymmm> numbers are used to describe the shape is all
[08:44:27] <Jymmm> psha: If I gave you two numbers: 3.14 and 180, what am I describing?
[09:07:27] <psha> Jymmm: nothing :)
[09:08:06] <psha> first you have to define _where_ you want to describe shapes
[09:08:14] <psha> in R^2, R^3, SO^2, SO^3?
[09:08:20] <psha> Z^2?
[09:08:22] <Jymmm> psha: bullshit, you know EXACTLY what I mean.
[09:08:34] <psha> i _guess_ you thing about half-circle

[09:09:19] <psha> but really degrees (which you think about 180) are not widely used in math
[09:09:29] <psha> raidans are more simple to deal with
[09:09:45] <psha> and thus your example becomes 3.14 and 3.14
[09:09:49] <psha> what it describes?
[09:09:53] <psha> nothing...

[16:02:42] <Tom_itx> latency wouldn't run even after installing the live cd
[16:03:52] <Tom_itx> another odd thing was, as a dual boot, linux used the windows background instead of it's own
[16:04:49] <Jymmm> http://i56.tinypic.com/zivknn.jpg
[16:05:39] <Tom_itx> is there an easy way to uninstall it and get rid of the dual boot?

[16:09:24] <Tom_itx> yeah i know about that option. i wanted to avoid it
[16:10:09] <JT-Shop> sorry I couldn't resist
[16:10:21] <JT-Shop> who got installed first?
[16:10:31] <Tom_itx> xp pro
[16:11:10] <Tom_itx> the only loss would be time. i have it all elsewhere
[16:11:51] <Tom_itx> i can leave it and run it like it is. i seldom reboot this one anyway
[16:11:54] <JT-Shop> can you just delete partition
[16:11:59] <Tom_itx> maybe
[16:12:09] * JT-Shop is just thinking out loud
[16:12:10] <Tom_itx> i didn't know if it would screw up the dual boot stuff
[16:12:48] <Tom_itx> and i can't resize the partition now

[16:14:55] <Tom_itx> it dosn't run properly so i was gonna get rid of it

[16:15:23] <Tom_itx> i can delete the partition, it's just that partition magic gripes about it now
[16:15:31] <Tom_itx> and i can't resize it
[16:15:37] <Tom_itx> so it's kinda useless
[16:15:57] <Tom_itx> unless deleting it would fix that
[16:16:39] <Jymmm> it'll become unpartitioned space, so as long as it's consecutive, should't be an issue resizing the other partition.
[16:16:55] <Tom_itx> the issue i wondered about was the dual boot stuff
[16:17:03] <Tom_itx> whether it would mess up the other one by deleting it
[16:17:28] <Jymmm> sure youll have to fix that too
[16:17:35] <Jymmm> not a big deal

[18:17:41] <danimal_garage> hopefully he's still there
[18:17:44] <Jymmm> Eh, that's different.
[18:18:08] <Jymmm> Wire transfer is funds from his bank account to your bank account.

[18:18:34] <Jymmm> Tell him you'll do Western Union instead.

[18:30:28] <IchGuckLive> that will resault in deeper marks at the Sandstone

[18:31:56] <danimal_garage> for ti? i use scotchbrite type pad on a D/A sander
[18:32:06] <danimal_garage> makes them look like the pics
[18:32:16] <Jymmm> so a brushed finish basically

[19:11:21] <tom3p> will 2.5 branch be gotten by 'git clone git://git.linuxcnc.org/git/emc2.git emc2-dev' ?
[19:11:33] <danimal_garage> i wonder how much my crappy little bandsaw is going to like cutting 7" diameter 7075 bar stock
[19:13:04] x_ is now known as micges
[19:13:32] <JT-Shop> tom3p: you have to do a git checkout branch_2.5 or something along those lines
[19:14:01] <JT-Shop> you might be able to do a git clone ... 2.5
[19:16:16] <tom3p> hmm, i was wonder what i'd get with that command ,
[19:16:17] <tom3p> because the desc on the web page says you get 'By default, you will get files from "master", which is the name for the branch where new feature development takes place'
[19:16:50] <tom3p> not familair with git, actually trying to get a clean starting point
[19:17:03] <JT-Shop> for 2.5?
[19:18:04] <tom3p> i'm not trying to get 2.5, i'm trying to know what to expect, sorry
[19:18:42] <JT-Shop> ok, git clone will get you master, git checkout (branch name) will get you the branch
[19:18:57] <tom3p> and master is .... what version
[19:19:05] <JT-Shop> no version
[19:19:18] <JT-Shop> it is master, ahead of any versions
[19:19:18] <tom3p> the thng i get has no version?
[19:19:52] <tom3p> ok, thats a concept that i dont 'git' a-tall
[19:19:57] <JT-Shop> at this point master will be 2.6 one day I assume as 2.5 branch has been created
[19:20:24] <danimal_garage> 2.6 is going to be released soon??
[19:20:26] <JT-Shop> before the 2.5 branch was created master was called ~pre 2.5
[19:20:37] <JT-Shop> 2.5 anin'
[19:20:45] <JT-Shop> ain't even released yet
[19:22:18] <alex_joni> master is ~pre-2.6 currently
[19:22:43] <alex_joni> but the next release will probably be a 2.4.7 (with bugfixes)
[19:22:55] <alex_joni> and after a longer period of time a 2.5.0, then 2.5.x
[19:23:06] <alex_joni> eventually (in a year or so) there will be a 2.6.0
[19:23:21] <alex_joni> maybe more/maybe less, depends on how things carry on
[19:23:38] <danimal_garage> wow i just got 2.5pre
[19:23:57] <danimal_garage> you guys move fast!
[19:24:06] <alex_joni> danimal_garage: 2.5pre is an older master (maybe 1-2 weeks old)

[20:58:33] <danimal_garage> do you think the Japanese are offended by the movie Godzilla?
[20:59:01] <kirk_wallace> I have an application where I run 'halrun foo.hal' form a terminal. When I exit the app, I get a 'halcmd:' prompt where I need to type quit, then 'exit' from the terminal.

[21:00:02] <andypugh> Does halrun source foo.hal work? (This is me guessing)
[21:00:38] <andypugh> Ah, actually checking the docs, try halcmd -f foo.hal

[21:06:37] <kirk_wallace> ´╗┐morficmobile: Not me,sorry. Is there a chance your question is more generic?
[21:08:15] <morficmobile> nope, i used both, but not recent enough to give much of an opinion about either as they currently are, was just wondering if i could solicit some more recent, live opinion about both
[21:08:23] <mikegg> I'm using BobCAD/CAM
[21:08:27] <mikegg> sigh
[21:08:38] <morficmobile> BobCAD makes you sigh?
[21:08:50] <mikegg> it has it's quirks
[21:08:56] <mikegg> but all in all it's not too bad
[21:09:07] <mikegg> I have the solidworks plugin
[21:09:11] <andypugh> Last time somebody mentioned they used BobCAD it elicited expressions od sympathy
[21:09:50] <mikegg> you have to be careful about what you pick as your geometry for the tool path
[21:10:07] <mikegg> and the help file is pretty helpful
[21:11:31] <danimal_garage> i have mastercam experience
[21:12:05] <danimal_garage> what do you need to know?
[21:13:15] <danimal_garage> i use x3, it's pretty decent
[21:14:12] <danimal_garage> but i have nothing to compare it to except older versions of mastercam
[21:15:57] <kirk_wallace> The -I (interactive) parameter in halrun seems to tell halrun to hang around which seems reasonable, but without it, the app comes up does one pass and disappears. Maybe put a loop somewhere? If so, then how to get out of the loop?
[21:19:49] <morficmobile> danimal_garage: the comparison would be the thing i am curious about
[21:21:01] <morficmobile> like when you create geometry manually, do you always have to pick what kind of line you want to create? ( i am wondering how mastercam will be at those times where we program before the solid is done)
[21:22:13] <mrsunshine_> pcw_home, well i see to it that it doesnt get to hot :P
[21:22:15] <morficmobile> i am used to pick bound or unbound, then based on where on an existing line i click i automatically get the possible line parallel, perpendicular, angle from point, without trips to menu bar every time
[21:22:29] <mrsunshine_> just hot enough for the plastic to melt but not to make smoke =)
[21:25:24] <danimal_garage> morficmobile, when you enter the line's start, you can enter the length, and move the mouse around and it snaps at parrellel and perpendicular points, or you can just enter an angle as well
[21:25:39] <danimal_garage> or you can just type the endpoint
[21:26:08] <danimal_garage> or it will snap to another line's endpoint or a circle's tangentpoint, etc
[21:26:33] <danimal_garage> it's fairly decent, but it doesnt hold relations like solidworks
[21:28:18] <danimal_garage> if it's a somewhat involved sketch, i just do it in solidworks.
[21:29:01] <danimal_garage> it's WAY better than mastercam 9
[21:31:03] <andypugh> Not on Linux, but Alibre does all that pretty well, and is only $99
[21:32:42] <psha> kirk_wallace: depends on app
[21:33:47] <kirk_wallace> psha: http://wiki.linuxcnc.org/emcinfo.pl?ModIO , files near the bottom.
[21:34:27] <kirk_wallace> psha: The app is h_modio_config
[21:34:39] <danimal_garage> andypugh, i suspect the expensive part of mastercam is the toolpath generation
[21:35:16] <andypugh> I am not sure how good (or expensive) the Alibre CAM is, but it works with Freemill
[21:36:19] <psha> ^$^#! by default .c files are opened with notepad!
[21:36:23] <morficmobile> danimal_garage: thanks, helpful info, this just shows we have to fight for time :) , so we don't misjudge mastercam and virtualgibbs
[21:36:58] <psha> in wine!
[21:40:48] <morficmobile> danimal_garage: how is mastercam on tool clearances on lathe cycles? like if i cut a smaller OD behind a flange, does it know not to rapid through the flange, or do i have to tell it a retract X larger than the flange diameter?
[21:41:38] <psha> kirk_wallace: h_modio_config is not terminated? or terminated with signal?
[21:41:43] <danimal_garage> i believe it has stock recognition
[21:41:46] <skunkworks> can you get say - cylinder bores chromed?
[21:41:54] <skunkworks> (random)
[21:41:55] <psha> if you place some debug prints in signal handler you'll get some info
[21:42:03] <andypugh> psha: It's worse that that, Notepad doesn't wrap on unix line-ends
[21:42:15] <andypugh> skunkworks: Yes
[21:42:28] <andypugh> skunkworks: google Nikasil
[21:42:35] <skunkworks> andypugh: thanks
[21:42:36] <psha> kirk_wallace: locking may be due to locked serial device
[21:44:13] <morficmobile> danimal_garage: esprit doesn't :) so making sure you are clear adds so many more X values it makes "this is a similar part, let's start with that" so much less fun
[21:44:35] <morficmobile> danimal_garage: ok, i'll leave you be, this at least keeps my bias towards virtual gibbs in check :)

[21:45:11] <kirk_wallace> I think we are talking about two different problems. The older problem is getting a looping CR that locks up the PC requiring a power off reset.
[21:45:13] <danimal_garage> morficmobile, i think i generally tell it not to rapid through the part. If it is selected in the toolpath, it will not rapid through it, however i think you'd have to use stock recognition otherwise (and i have no clue how to use that, or what it does)
[21:45:32] <kirk_wallace> psha: okay thanks, g'night

Virtual gibbs' "balloons", like a larger version of a tool tip, nice way to go "wonder what the options i usually don't use on this dialog do", so you actually just work on the part, but also soak in a lot of "oh i need to try this next time"
[22:08:15] <danimal_garage> yea thats cool

[22:10:37] <mikegg> I just got a tormach R8 collet and one of their tool holders
[22:10:50] <mikegg> it's kinda cool
[22:11:03] <mikegg> air cylinder should be here wednesday
[22:13:17] <cpresser_> any hints how to center a endmill in its collet? i got a new end-mill which is about 3" long. unfortunately it runs a little excentric.
[22:14:10] <cpresser_> it gives a lot of vibration.. an worst, i cant work exact
[22:14:21] <cpresser_> the collet is a ER11 type
[22:15:29] <mikegg> are your spindle bearings tight?

[22:16:14] <mikegg> the lock nut on my spindle has worked loose with vibration in the past

[22:23:12] <cpresser_> good point, i will check that
[22:24:32] <tom3p> make sure the collet seat is concentric and clean,
[22:24:33] <tom3p> put the tip of your indicator on the seating surface and spin by hand.
[22:25:04] <tom3p> the tool in the collet will never be better than that reading
[22:25:06] <morficmobile> cpresser_: they are not designed to be anything but concetric, check if you have runout on the collet taper itself, a little bit there is worse 3" further away from there
[22:25:24] <morficmobile> tom3p: always beating me to what i type! :)
[22:26:04] <morficmobile> time to go home, have a great evening gentlemen
[22:26:12] <tom3p> gnite
[22:27:45] <cpresser_> i should get a 'real' spindle, not that DIY-Crap i am using now :/
[22:27:53] <tom3p> i cant open any of the supplied .ui files in gladevcp , always segfaults
[22:28:58] <tom3p> anyone have luck with gladevcp?

[22:53:35] <danimal_garage> is there any ways to change the max accel for an axis without restarting emc?
[22:53:42] <danimal_garage> like with halcmd or something?
[22:54:34] <alex_joni> halcmd setp axis.*.max-vel or such
[22:55:00] <alex_joni> there is also a tuning utility which can set some params, can't recall if maxvel is one of them
[22:56:31] <danimal_garage> ah cool thanks
[22:56:59] <danimal_garage> machine calibration doesnt set vel or acel

[23:24:09] <MattyMatt> cpresser_: your "DIY-Crap" sounds like my next significant upgrade :) ER11+608s wiil be better than the dremel I'm using now
[23:27:15] <MattyMatt> the ER11 straight shank chuck I'll get costs $15, but there's a £45 equivalent which has good reviews
[23:28:52] <MattyMatt> the cheap one http://cgi.ebay.com/ER11-8MM-STRAIGHT-SHANK-CHUCK-CNC-MILLING-LATHE-D66_W0QQitemZ150573752140

[23:36:10] <MattyMatt> a pair of ABEC7 608s and that should be OK IMO
[23:37:24] <MattyMatt> I can't find the posh one ATM, which has rave reviews on the lines of "no measurable runout, needle hardly wobbles so less than 0.0001"

[23:41:00] <MattyMatt> they quote the same review on all their sizes, so I won't take that as a guarantee :)
