[03:02:32] <atom1> does emc not like line numbers?

[03:03:31] -!- guz has quit [Client Quit]
[03:03:36] <atom1> oh i bet it's the () with no O word
[03:04:19] <atom1> nope

[03:05:52] <atom1> at or near line 3 it says
[03:06:50] <FinboySlick> atom1: I typically get rid of the O part.
[03:07:12] <atom1> i'm just testing a program i had so i can adjust my cam post
[03:07:27] <atom1> one i know works with my old control
[03:08:05] <atom1> that must have been it though
[03:08:43] <atom1> but O words are valid gcode
[03:08:59] <atom1> what do you use for file comments then?
[03:09:51] <atom1> the () by themselves seem to be ok
[03:09:59] <atom1> hrm
[03:11:43] <atom1> what is op stop? M1?

[03:47:57] -!- Aero-Tec has quit [Ping timeout: 258 seconds]
[03:52:03] <FinboySlick> O words are valid, but they don't seem used to name the program in EMC.
[03:52:50] <FinboySlick> atom1: At least, that's what my noob mind understood when I faced the same issue. I'm definitely no expert.
[03:53:24] -!- Aero-Tec [Aero-Tec!~chatzilla@] has joined #emc
[03:54:00] <FinboySlick> atom1: Try without the initial O statement and keep your hand on the estop?
[03:54:06] -!- dgarr has quit [Quit: Leaving.]
[03:55:24] <atom1> it works with just the () so that's no big deal as long as i know what it wants
[03:55:32] <atom1> i'll just adjust my cam post
[03:56:18] <atom1> my other control ignored M1 too so i added toolchanges so it would stop for me so now i can change all those back to M01 op stops
[03:57:00] <atom1> i can sure see how a touch probe would speed setup up alot
[03:57:24] <FinboySlick> Making one is high on my list of projects.
[03:57:36] <atom1> i'm gonna make another one but smaller
[03:58:51] <atom1> http://tom-itx.dyndns.org:81/~webpage/emc/probe_index.php
[03:59:41] <FinboySlick> atom1: Yeah, that's pretty much what I'm aiming for too.
[04:00:15] <atom1> i need a small one for my sherline since there's not alot of z
[04:01:18] <FinboySlick> atom1: Heh, you're still lucky you can fit 3/8 things in it. I'm limited to 1/4.... Was very hard finding a proper edge finder.

[09:06:53] <Loetmichel> i only hope there is nothing else broken in the phone. so if i get the new lcd and moint it it will work as new
[09:14:34] <Jymmm> just take your time dis/assembling it
[09:19:20] <Loetmichel> will do
[09:19:51] <Loetmichel> i just fear my 108kg weight wans so good for the internal electronics either
[09:20:24] <Jymmm> call it and see if it still works
[09:20:37] <Loetmichel> the interesting part is that the lcd is broken THROUGH the casing. the front "gorilla" glas panel ISNT broken, just the lcd ;-)
[09:20:44] <Loetmichel> it works
[09:20:58] <Loetmichel> even the wlan /BT part works
[09:21:09] <Loetmichel> it SEEMS that just the disply is damaged.
[09:21:30] <Loetmichel> but you'l never now if a PCB got fine cracks
[09:21:55] <Loetmichel> which will develop malfunctions over time

[12:37:18] <jthornton> any suggestions for a billion mega pixel camera that fits on your pinky? Wife thinks my 3Mp Olympus is too big to fit in her purse...
[12:39:49] <Jymmm> JT-Shop: This and a spare battery off ebay for $2 http://www.walmart.com/ip/Sanyo-VPC-E1500TPLB/15105549
[12:41:14] <jthornton> you have one Jymmm?
[12:42:37] <Jymmm> JT-Shop: Not THAT model, but a 10MP Sanyo model from a few years ago. Recharges flash quickly, focuses good for a PNS, easy to use, records audio, photo, video.
[12:43:37] <jthornton> seems like a good value
[12:43:46] <jthornton> how long does the battery last?
[12:44:00] <Jymmm> JT-Shop: you don't like it, return it within 90 days to any store
[12:44:36] <jthornton> thanks, time for me to run
[12:44:44] <Jymmm> JT-Shop: It last a while, just dies quickly and the batteries (in my gf's) was like $1.50 off ebay

[13:02:10] <Jymmm> jthornton: the reviews seem to be mixed, only 90 day warranty, seems an issue with some units regarding battery.

[14:11:16] <Tom_itx> so i can use that now
[14:11:29] <Jymmm> (It does, but you'll be using a lot of F words when you do)
[14:11:31] <anonimasu> bbl, gotta run to prepare for dinner

[16:28:51] <n0b> how do the tool diameters in the tool table affect gcode?
[16:29:37] <skunkKandT> if you are using cutter comp - it uses the tool diameter to create the tool path offset from the programmed path

[21:10:25] <Jymmm> SWPLinux: Nobody's listening
[21:10:26] <SWPLinux> you'll have to wait for the product announcement
[21:12:52] <mhaberler> SWPLinux: while we aptiently wait ;-) - any comments on http://comments.gmane.org/gmane.linux.distributions.emc.devel/4888 =
[21:13:48] <SWPLinux> yeah, sorry we never seem to meet on IRC :)
[21:13:56] <mhaberler> not yet, this is the day
[21:15:49] <SWPLinux> well, I will need to go soon, but I can comment a little now
[21:16:21] <SWPLinux> first, I don't know if the behavior you describe is new (in 2.5 or something), or if it's been there the whole time
[21:17:00] <SWPLinux> your comments did cause me to take another look at the code, and there are a couple of changes I would make to get it to work as originally designed anyway
[21:17:37] <mhaberler> do you agree with my proposed changes?
[21:18:13] <SWPLinux> the reason I wonder if the behavior has changed is that I'm pretty sure it used to turn off the output while disabled
[21:18:47] <mhaberler> I am referring to v2.5_branch but I admit I havent done the archeology
[21:19:28] <SWPLinux> what I would do instead of a turn-on delay, would be to keep the transition detectors going, even while enable-in is off
[21:20:00] <SWPLinux> so the process function, which currently does nothing if not enabled, would continue processing regardless of enable-in
[21:20:23] <mhaberler> fine, as long as it doesnt do false positives, which dangerous IMO
[21:21:47] <SWPLinux> the transition detectors would maintain an internal table of detection status, and those would be ANDed with the enable to get the output value
[21:21:58] <mhaberler> YES
[21:21:58] <FinboySlick> SWPLinux: I'm assuming from the talk that you're an EMC dev?
[21:22:14] <SWPLinux> output becomes more or less enable AND detector1good AND detector2good ...
[21:22:25] <SWPLinux> kinda sorta, when I have the time :)
[21:22:27] <mhaberler> so I understand you'll fix it, which spares my pushing hotdog.9 which does it the haberler way ;-)
[21:23:01] <SWPLinux> heh
[21:23:14] <SWPLinux> I didn't say I had the time to *code* it :)
[21:23:16] <mhaberler> well time. IMO this should not be in v2.5_branch in its current form.
[21:23:39] <FinboySlick> SWPLinux: Since you likely know this a lot more than I, would you mind having a peek at something when you get a moment? I'm trying to build on uClibc and I think I have one of the hurdles cleared but I'm not smart enough with C to know if my solution is a proper fix.
[21:24:22] <SWPLinux> is it something small enough for me to read in 5 minutes?
[21:24:34] <FinboySlick> Actually, it's not quite EMC yet, I'm trying to fix RTAI ;) Kinda... It's just a header replacement.
[21:24:35] <SWPLinux> I don't have a lot of experience with uClibc
[21:24:54] <FinboySlick> You got magma sources handy?
[21:25:07] <mhaberler> SWPLinux: I propose either you take the ticket for 2.5, and I review, or vice versa, but this shouldnt be there
[21:25:57] <SWPLinux> mhaberler: that's OK by me. I know I won't have any time for coding until some time next month though
[21:26:08] -!- ries has quit [Ping timeout: 248 seconds]
[21:26:12] <FinboySlick> Basically, rtai_math.h appears to be a custom version of math.h, but it calls the OS version of mathcalls.h instead of its own... Which I find odd assuming that they re-implement libm.
[21:27:03] <FinboySlick> My 'fix' is to provide it with its own version of mathcalls.h (which I've dubbed rtai_mathcalls.h), instead of it using uClibc's which is different from what it expects.
[21:27:40] <mhaberler> SWPLinux: ok, I'll take a stab and let you know.
[21:27:55] <SWPLinux> mhaberler: thanks

[21:29:29] <FinboySlick> SWPLinux: That's fine. Felt good just letting it off my chest ;)
[21:29:30] <SWPLinux> I would have to delve into a bunch of stuff to (try to) figure it out, and I just don't have the time at the moment
[21:29:37] <SWPLinux> well good then :)
[21:30:01] <SWPLinux> hey, the sun is up

[22:33:25] <robin_sz> some tasty laser collimator
[22:34:28] <FinboySlick> Sheesh, that little alix box might be underpowered but it looks like it's going to be terribly fast.
[22:34:43] <FinboySlick> I hope the latency tests turn out good.
[22:36:02] <robin_sz> we were playing "lets cut up bits of cardboard with a laser" yesterday .. oodles of fun
[22:36:17] <robin_sz> 10W on a 100um spot works very nicely
[22:37:09] <FinboySlick> robin_sz: out of curiosity, how many watts does one have to feed a laser like that for it to output 10W? Is it efficient?
[22:37:32] <robin_sz> oh, not much .. 3 or 4kw maybe
[22:37:54] <FinboySlick> 3kw of electricity ofr 10w of light?
[22:38:02] <robin_sz> yeah,
[22:38:08] <FinboySlick> Sheesh.
[22:38:15] <FinboySlick> That's a lot of wasted heat.
[22:38:18] <robin_sz> to be fair, thats not fair really
[22:38:24] <robin_sz> as it was a green one
[22:38:32] <robin_sz> so lower efficiency
[22:38:53] <robin_sz> 4% efficiency is more typical for CO2
[22:39:21] <robin_sz> hmm .. my big 2000W trumpf used to pull 80kw
[22:39:30] <robin_sz> thats what .. 6% efficiency?
[22:40:15] <FinboySlick> Wow...
[22:40:33] <robin_sz> green ones are less efficient
[22:40:46] <robin_sz> you generate 100W of 1064nm from a YAG
[22:41:00] <robin_sz> and then frequency double it to 532nm
[22:41:11] <robin_sz> the doubling process is low efficiancy
[22:41:26] <robin_sz> but WAY cool to play with :)
