Back
[00:01:13] <rayh> This a US keyboard?
[00:01:27] <wb9mjn> Anyway...doing laundry....be back later...Will try it a few more times to see if I can catch anything odd...it goes pretty fast...
[00:02:08] <wb9mjn> Its a standard PS 2 keyboard...originailly from a HP Pavilion Pentium 1....been using it for years...it works fine if I have the CD out and let
[00:02:15] <wb9mjn> rc_46 boot...
[00:02:17] <rayh> Try pressing escape a couple times during.
[00:02:30] <rayh> start.
[00:02:33] <wb9mjn> Ok...
[00:02:39] <rayh> before it goes into the cd
[00:03:09] <Jymmm> ALPHA-EMC: Well, take a pic, lets see the results.
[00:46:17] <wb9mjn> Hi Ray....Hit the ESC before and after....Before it dumped into a "Select boot Device" Menu...After no difference from previously...
[00:46:52] <wb9mjn> On the "Select Boot Device" menu, just hit return and it returned to the booting from CD....

[00:58:10] <Jymmm> ~~~~~
[01:43:12] <K`zan> G'day all
[01:45:03] <A-L-P-H-A> * A-L-P-H-A pokes K`zan
[01:45:24] <A-L-P-H-A> Jymmm, I got a scanner... sec.
[01:47:21] <K`zan> Jymmm: Tanks for the pointer, kicad is in portage, even if I do have to add ~amd64 to package.keywords for it :-) Will check it out, been using gEDA.
[01:47:27] <K`zan> A-L-P-H-A: What!
[01:47:38] <A-L-P-H-A> * A-L-P-H-A pokes K`zan harder
[01:47:53] <K`zan> * K`zan swats A-L-P-H-A with a vice :-)
[01:48:31] <K`zan> Got the slot for the dovetail milled out, now just got to wait for the 1/2" collet to get here to finish it up.
[01:49:05] <K`zan> CNC will be nice, if for nothing else, to save all the cranking :-).
[01:49:23] <A-L-P-H-A> http://74.118.149.89/emc/LL_was_here2.png
[01:50:06] <A-L-P-H-A> Jymmm: http://74.118.149.89/emc/LL_was_here2.png
[01:50:35] <A-L-P-H-A> there was a little messup on the "o"
[01:51:00] <A-L-P-H-A> either the ball in the pen skipped or something else.
[01:51:03] <A-L-P-H-A> no clue really.
[01:51:26] <K`zan> Cheap ball points will do that.
[01:51:54] <A-L-P-H-A> I didn't have any clicky pens, so it was a freebee from my best friend.
[01:51:55] <K`zan> Now I am back to square one on the CNCing of my mill thanks to you and Jymmm :-).
[01:52:09] <A-L-P-H-A> I had to go over to his house to get it... that too more time than making the bloody holder.
[01:52:14] <K`zan> Not a Mont Blanc I would guess :-)?
[01:52:29] <A-L-P-H-A> I think I'll go look for a gel pen... that would be way better.
[01:52:46] <K`zan> Worth a shot, or just get a Mont Blanc refill.
[01:53:07] <A-L-P-H-A> Mont Blanc won't fit my pen holder.
[01:53:12] <K`zan> :-)
[01:53:32] <K`zan> Draw it twice, probably won't skip in the same place twice.
[01:53:36] <Jymmm> A-L-P-H-A: It turned out pretty good... what's with the squiggles?
[01:53:49] <A-L-P-H-A> Jymmm, I had "Z" axis direction reverse.
[01:53:55] <Jymmm> ah
[01:53:56] <K`zan> Jymmm: Sorry if I pissed you off last night....
[01:53:57] <A-L-P-H-A> so I did it again, without changing papers.
[01:54:26] <Jymmm> K`zan: I don't even remember
[01:54:45] <K`zan> :-), me either, I was really beat last night, all that cranking wears one out :-).
[01:55:21] <Jymmm> I think A-L-P-H-A was the one being the pita more so than you K`zan
[01:55:33] <K`zan> Yeah, he is good at that kind of thing ;-)
[01:56:15] <A-L-P-H-A> I'm always a pain in the ass.
[01:56:23] <K`zan> BTW, apparently the problem I was having with the emc2 CD was that while the CDs say they will burn at 40x, they don't. Slowed it down to 16x and it worked fine.
[01:56:25] <A-L-P-H-A> that's why y'all wuv me.
[01:56:39] <A-L-P-H-A> K`zan, stop buying cheap stuff. :)
[01:56:44] <K`zan> With a 5 pound sledge we wiv ya :).
[01:56:45] <Jymmm> Jymmm has kicked A-L-P-H-A from #emc
[01:56:54] <K`zan> LOL
[01:57:01] <A-L-P-H-A> whanker.
[01:57:16] <Jymmm> A-L-P-H-A: That's so you know how much I care =)
[01:57:16] <K`zan> Yeah, you are, but generally tolerable :)
[01:57:39] <K`zan> Cheap shit or keep cranking, I dunno...
[01:58:18] <A-L-P-H-A> http://74.118.149.89/drawboard that's my pen holder design... just shoved the spring on the other side of the notch on the ink tube. bored a 3mm hole all the way through, and a 9/32 bore to find the pen nozzle.
[01:58:47] <A-L-P-H-A> Jymmm, stop sharing your foot fetish with me.
[01:58:53] <Jymmm> all I see is grey screen
[01:58:57] <A-L-P-H-A> java.
[01:59:06] <Jymmm> disabled =)
[01:59:08] <K`zan> Actually, with the geckos and 3 267 oz.in steppers, it is only $100 more without the fan and PS.
[01:59:17] <K`zan> Less shipping.
[01:59:26] <A-L-P-H-A> K`zan, geckos are way way better... get the G212
[01:59:33] <A-L-P-H-A> or G210
[01:59:37] <A-L-P-H-A> I suggest the G212
[01:59:56] <K`zan> I might be able to hack that old 24V power wheelchair supply to drive stuff.
[02:00:07] <K`zan> Lemme see if I have a link for them.
[02:00:22] <A-L-P-H-A> if you have the amps in them, great.
[02:00:39] <K`zan> Amps? in a power supply?
[02:00:49] <A-L-P-H-A> the transformer
[02:00:53] <A-L-P-H-A> amp rating
[02:01:05] <K`zan> 10A according to the meter on it.
[02:01:19] <K`zan> Husky transformer - heavy...
[02:01:40] <A-L-P-H-A> uh... I think it's good enough. :D
[02:03:06] <K`zan> No luck with google, got a link?
[02:03:11] <A-L-P-H-A> I'm thinking of charging my buddy $600CDN for the geckos G201 + power supply.
[02:03:26] <K`zan> Ouch
[02:03:43] <A-L-P-H-A> used... and go with the G212, so I can say "F-you" to the microstepping, but still get the higher speeds, and smoothness from the geckos.
[02:06:22] <K`zan> $114 vs $170 per axis...
[02:06:31] <K`zan> 201 vs 212
[02:07:12] <A-L-P-H-A> Yup.
[02:07:19] <A-L-P-H-A> big diffs...
[02:07:35] <A-L-P-H-A> K`zan, depends on how fast you want to move stuff.
[02:07:51] <A-L-P-H-A> 201 is 10uStepping... 212/210 is selectable.
[02:09:16] <K`zan> What is "UVLO" ?
[02:09:23] <jepler> under-voltage lock-out
[02:09:37] <jepler> a circuit that detects a supply voltage is below spec and does something about it
[02:10:05] <A-L-P-H-A> looks like I don't need a 400uF 100V cap with the G212
[02:10:06] <K`zan> Not all that concerned with speed at this point, the uMill is not a Bridgeport :)
[02:10:15] <K`zan> jepler: Thanks!
[02:10:30] <jepler> K`zan: welcome
[02:10:39] <A-L-P-H-A> K`zan, but it's a pain to wait... :D but I'm impatient.
[02:11:09] <A-L-P-H-A> jepler, check out my pen drawing results, gcode courtesy of Jymmm. http//74.118.149.89/emc/LL_was_here2.png
[02:11:54] <A-L-P-H-A> http://74.118.149.89/emc/LL_was_here2.png
[02:12:22] <K`zan> A-L-P-H-A: So what is wrong with this one: http://www.hobbycnc.com/hcncpro.php
[02:13:10] <K`zan> A-L-P-H-A: At me age, one learns patience whether one wants to or not :).
[02:13:11] <A-L-P-H-A> amps rating... I think I had a motor that 3.4amps.
[02:13:23] <A-L-P-H-A> pretty sure I did.
[02:13:29] <K`zan> The steppers I want are:
[02:13:51] <K`zan> http://www.xylotex.com/StepperMotor.htm
[02:14:02] <K`zan> That oz,in range anyway.
[02:14:45] <Jymmm> K`zan: Just remember, that you can always use the geckos on another/bigger machine. Where as the Xylotex you're kinda stuck.
[02:15:02] <Jymmm> K`zan Those are the steppers I have.
[02:15:34] <K`zan> Jymmm: True, I can also upgrade the drivers later too, if the need arises.
[02:16:10] <K`zan> I think I would rather face that than wait another 6 months or so to get super drivers now...
[02:16:30] <Jymmm> K`zan: Now, when I get about 2 hours into a job, I have problems with stalling and I havne't been able to determine where the problem is exactly. I *THINK* it's a thermal issue, mostly inside the enclosure of my machine (not a lot of ventilation)
[02:16:57] <K`zan> That is with the xylotex, right?
[02:17:01] <Jymmm> yes
[02:17:34] <Jymmm> I spent about $400 on Xylotex.... 3 steppers, driver and PS
[02:17:35] <K`zan> Ah, he seems to make it clear that his driver needs ventalization badly - recommends 2 fans on the board.
[02:17:47] <A-L-P-H-A> oh... that's pretty cheap
[02:17:48] <Jymmm> K`zan: Heh, I have SIX fans on it
[02:17:48] <K`zan> Jymmm: That is what I am looking at, the 3 axis ready.
[02:18:05] <A-L-P-H-A> I think I would have spent $1000CDN for all that with geckos.
[02:18:08] <A-L-P-H-A> but way bigger steppers.
[02:18:29] <K`zan> Jymmm: It does seem to me that the heat sinks on the xylotex are pretty sad.
[02:19:10] <K`zan> And it doesn't look like one can change them to something better, from what I can tell by looking at the pix.
[02:19:33] <Jymmm> K`zan Eh, I had read all the forum posts on that, and I even had to return the board once for repair when I attached a faulty stepper to it
[02:19:34] <K`zan> A-L-P-H-A: Yeah, easily.
[02:20:02] <K`zan> Jymmm: the HobbyCNC is starting to look better - get the driver from him and the steppers from Xlyotex.
[02:20:23] <K`zan> HobbyCNC one is protected for stuff like that and has a thermal shutdown.
[02:20:24] <Jymmm> K`zan: You can't do that... HobbyCNC is unipolar,
[02:21:05] <K`zan> Ah, right :-(. Maybe look for other sources of 6-8 wire 269 oz.in steppers then. WOW this gets complex in a hurry :-).
[02:21:17] <K`zan> "4 wire steppers won't work"...
[02:21:24] <K`zan> Sigh
[02:21:28] <A-L-P-H-A> I bought my whole shop, with tooling, for $4K CDN... I came with a lathe, mill, two bench grinders, grinite block, surface height guage, bandsaw, two laptops, lots of alu stock, miller mig welder, drill press... two collet sets, multiple vises...
[02:21:29] <Jymmm> Xylotex steppers are bi-polar
[02:21:39] <A-L-P-H-A> steppers, and controllers (solder the controllers)
[02:21:42] <A-L-P-H-A> air compressor...
[02:21:42] <K`zan> 200 oz.in are really marginal for the micro-mill from what I can gather.
[02:21:57] <A-L-P-H-A> it was a steal.
[02:22:17] <K`zan> A-L-P-H-A: VERY nice to have the scratch to be able to do that, seem like a GOOD deal.
[02:22:34] <Jymmm> K`zan: If you get the xylotex steppers, grab some knobs from radio shack for the back shaft.
[02:22:48] <A-L-P-H-A> buddy wanted $10K for it... originally... I just held out... then said, $6K without papers... I told him I only had $4K... he said he'd do it... so I think I ended up with $4.4K outta my pocket.
[02:22:59] <K`zan> Jymmm: Will do, one thing I really like about those steppers is the double shaft.
[02:23:19] <K`zan> A-L-P-H-A: Lucky all the way around :-).
[02:23:35] <A-L-P-H-A> yeah... I was.
[02:23:54] <Jymmm> K`zan: http://www.radioshack.com/product/index.jsp?productId=2102831&cp=&origkw=knob&kw=knob&parentPage=search
[02:24:14] <K`zan> Seattle has no industrial base to speak of so it is hard to find deals here...
[02:24:29] <A-L-P-H-A> this was the guy's home shop
[02:24:59] <K`zan> Love that idea, NICE home shop, dreaming, drooling :-).
[02:25:27] <K`zan> Jymmm: Friend just sent me all his old AVR/junk and there were two packages of those in there - perfect is hard to beat LOL!
[02:25:55] <K`zan> Thought that number looked familiar :-)!
[02:27:20] <jepler> $73/axis (driver only), using the same chip as xylotex but different heatsinking: http://www.pmdx.com/PMDX-150/index.html
[02:27:45] <A-L-P-H-A> Jymmm, what'd you use to make that gcode for me earlier?
[02:29:10] <Jymmm> I already told you
[02:29:49] <A-L-P-H-A> you said love.
[02:29:51] <A-L-P-H-A> seriously.
[02:29:56] <Jymmm> seriously.
[02:30:01] <K`zan> jepler: THanks, looks like a better deal than the xlyotex drivers.
[02:30:20] <K`zan> And seperate axis drivers make replacement a lot easier in case of problems.
[02:30:50] <jepler> K`zan: I notice it has thermal protection, which you mentioned was important to you.
[02:30:52] <A-L-P-H-A> Jymmm, man... why can't you just paste a url or something
[02:31:14] <K`zan> +Over-temperature shutdown and lockout. If the driver senses excessive thermal conditions it will turn off its output, pull the opto-isolated fault output to ground, and signal the fault by flashing the status LED. It is then necessary to cycle power or push the test button to clear the fault. This prevents the driver from cycling in and out of shutdown and makes sure that the operator knows to correct any erroneous motion before continui
[02:31:14] <K`zan> ng.
[02:31:17] <K`zan> Like that...
[02:31:22] <jepler> K`zan: my only experience with those boards was that I met steve stallings at cnc workshop this year, and he was running them on his demo mill.
[02:31:24] <A-L-P-H-A> jepler, did you use a center drilling for your stippling cat?
[02:31:46] <K`zan> stippling cat?
[02:31:54] <A-L-P-H-A> stippling cat is awesome!
[02:32:00] <jepler> A-L-P-H-A: I used a 60-degree mill that cradek usually uses for pcb milling (trace isolation)
[02:32:39] <K`zan> jepler: Thanks for the pointer, appreciate it - seems that as I get closer to being able to do this, that it is getting infinitly more complex... Get with it and upgrade later as needed or keep waiting (and cranking :-)?
[02:32:59] <jepler> K`zan: see http://emergent.unpy.net/software/01133127497-stippler-source-release and the links "discussed it before" for some photos
[02:33:12] <A-L-P-H-A> jepler, oh. okay
[02:33:22] <K`zan> Wondering just how underpowered the 200 oz.in hobbyCNC ones would be for the uMill...
[02:33:25] <K`zan> jepler: checking...
[02:33:36] <A-L-P-H-A> http://emergent.unpy.net/files/01109259892/img_9023.jpg
[02:34:51] <A-L-P-H-A> just realized my pen won't work with the stippler...
[02:34:59] <A-L-P-H-A> I'd need a marker instead.
[02:37:06] <jepler> A-L-P-H-A: for the edge-lit stuff I think the best thing is a small-diameter conical hole that doesn't pass all the way through to the front side
[02:37:53] <jepler> a tinier diameter means it looks more like a point, but greater depth means you collect more light
[02:37:54] <A-L-P-H-A> I was just going to use the small point on the centre drill, without going past the point.
[02:38:00] <jepler> that said, the 60 degree tool was the only thing I actually tried
[02:38:51] <A-L-P-H-A> I was goin to use the 60 degree point of the centre drill... you know how it it's a thick shaft, 60° in, to a small stubby shaft, then goes another 60° point?
[02:39:09] <jepler> it sounds like it's worth a try
[02:39:14] <jmkasunich> I think that smaller point isn't 60 degrees
[02:39:18] <A-L-P-H-A> http://www.sherline.com/images/3021pic.jpg
[02:39:27] <jmkasunich> bet it's 118 degrees like a normal drill bit
[02:39:31] <A-L-P-H-A> oh, maybe it's 118
[02:40:30] <jepler> http://thinktink.com/stack/volumes/voli/store/mechmill.htm
[02:40:42] <jepler> they call it a "mechanical etching bit"
[02:41:19] <A-L-P-H-A> I also have 1/32 end mills.
[02:43:27] <K`zan> Hadn't thought of this until now, but I wonder if PCB drill files can be converted to gcode, would be a nice use for the mill...
[02:43:35] <A-L-P-H-A> yes
[02:43:36] <A-L-P-H-A> they can
[02:43:39] <jepler> A-L-P-H-A: try several different methods on a single piece of plexiglass... you can light them all at once and see which is best
[02:43:40] <A-L-P-H-A> I did that with my mill.
[02:43:44] <K`zan> Coooooooooollllllllllllll :-)
[02:43:53] <A-L-P-H-A> eagle can do it.
[02:44:09] <jepler> K`zan: http://timeguy.com/cradek/cnc/pcb
[02:44:09] <A-L-P-H-A> isolation traces, and the drill files can be used to drill the boards for you
[02:44:11] <K`zan> That would be helpful, except I don't use eagle :-(. gEDA
[02:44:14] <A-L-P-H-A> no etching required aftwards.
[02:45:28] <jepler> if you write it for gEDA it will be possible
[02:45:29] <K`zan> Heh, my new "CNC Related" folder is sure filling up fast :).
[02:46:09] <K`zan> PCB spits out, I think, an ?"exelon"? drill file, will have to look at that and see what is what.
[02:46:11] <jepler> you can also give up free-software ideals and use the freeware version of eagle if you're producing non-commercial designs only
[02:46:29] <jepler> goodnight all
[02:46:36] <jmkasunich> goodnight jeff
[02:46:41] <A-L-P-H-A> night jepler
[02:46:44] <K`zan> jep, after gEDA, eagle is kind of ugly and klunky, but I'll look into it again.
[02:46:50] <K`zan> Night, jepler rest well and thanks!
[02:48:57] <K`zan> So many options, so little $$$ :-)
[02:54:24] <K`zan> kicad looks interesting, but first thing I will have to do is make up parts for the AVR chips I use.
[03:05:06] <A-L-P-H-A> cnc porn... :( http://forums.bit-tech.net/showthread.php?t=76374&page=1&pp=20
[03:08:00] <K`zan> Yeah, it is LOL! Nice case and even nicer shop.
[03:08:51] <A-L-P-H-A> wish I had a 12x12 area to work with...
[03:08:58] <A-L-P-H-A> wonder if I could make a 12x12 milling machine.
[03:09:05] <K`zan> Good deal on end mills from Enco: http://www.use-enco.com/CGI/INSRIT?PMAKA=RM320-9001
[03:09:10] <A-L-P-H-A> I'm in Canada!
[03:09:14] <K`zan> So ?
[03:09:29] <A-L-P-H-A> enco doesn' t ship up here... if they do, it's way too expensive
[03:09:33] <K`zan> You can fix that by moving to a real country ;-) <gd&r>
[03:09:40] <A-L-P-H-A> bhuauhahahaa
[03:09:46] <A-L-P-H-A> yeah. and loose my freedoms, and shit.
[03:09:56] <K`zan> Really? Wonder why, probably closer to you from Enco than I am out here on the left coast.
[03:09:57] <A-L-P-H-A> so I would have to show ID to trave within the same country.
[03:09:59] <A-L-P-H-A> [i.e. fly]
[03:10:07] <K`zan> Heh, what freedoms?
[03:10:09] <A-L-P-H-A> cross boarder
[03:10:44] <K`zan> I considered moving to Canada, but I won't live anywhere where they disarm the citizens...
[03:11:05] <K`zan> Same for .au unfortunately.
[03:12:08] <A-L-P-H-A> uh... why do you need to own a gun?
[03:12:23] <K`zan> Until they clean up the security to do with flying I won't fly anymore.
[03:12:26] <jmkasunich> cause its fun putting holes in paper from a distance?
[03:12:34] <A-L-P-H-A> In almost every city in Canada, I don't know of one, that I wouldn't feel safe enough to just walk down.
[03:12:46] <K`zan> You ever been dragged out of your car by a big black dude?
[03:13:00] <A-L-P-H-A> K`zan. Nope... cause they don't do that shit up here.
[03:13:05] <Jymmm> K`zan: Yes, A-L-P-H-A has
[03:13:07] <K`zan> Horseshit...
[03:13:09] <K`zan> LOL
[03:13:19] <K`zan> He probably liked it, lefties do ;-)
[03:13:32] <K`zan> LOL, just picking on you A-L-P-H-A :-).
[03:13:38] <jmkasunich> come on guys, lets not get political here
[03:13:39] <A-L-P-H-A> <shrug>
[03:13:43] <jmkasunich> plenty of other places for that
[03:14:01] <Jymmm> jmkasunich You tell that to A-L-P-H-A for the last 36 hours, then we'll talk.
[03:14:31] <A-L-P-H-A> anyways...
[03:14:35] <K`zan> LOL
[03:14:38] <A-L-P-H-A> I want to draw more on my mill.
[03:14:48] <K`zan> You are mean :-)
[03:14:58] <K`zan> So do I, but not yet...
[03:15:04] <K`zan> Sigh...
[03:15:11] <K`zan> Crank on dudette :-/.
[03:15:22] <A-L-P-H-A> dudette?
[03:15:24] <A-L-P-H-A> wtf?
[03:15:32] <K`zan> Huh?
[03:15:37] <A-L-P-H-A> oh, you're talking about yourself
[03:15:38] <A-L-P-H-A> nm
[03:15:49] <K`zan> Yep
[03:15:53] <A-L-P-H-A> thinking, photoshop some thing, stylize it, use some image to gcode software...
[03:16:01] <K`zan> That cranking does get old quite quickly.
[03:16:17] <A-L-P-H-A> K`zan, how do you think I made my shitty ball screw brackets?
[03:16:27] <A-L-P-H-A> by hand cranking them out on the mill.
[03:16:28] <K`zan> I don't so much mind the math, but my wrists are sore after that little tool holder bracket and two slots...
[03:16:47] <K`zan> Yep, understand, but that is my only option for the moment.
[03:17:03] <A-L-P-H-A> decided on geckos or not?
[03:17:08] <K`zan> Wonder why the xylotex looks so good to me :-)?
[03:17:15] <K`zan> Probably not immediately.
[03:17:17] <A-L-P-H-A> $$?
[03:17:29] <K`zan> Yep, the problem is indeed $$$ :-(.
[03:17:47] <K`zan> It took me about 6 months to get here from where I was.
[03:18:04] <A-L-P-H-A> I hear there's a thriving adult entertainment market in Seattle.
[03:18:27] <A-L-P-H-A> OH! I know what to draw.
[03:18:34] <A-L-P-H-A> my company logo. :D www.firstfire.ca
[03:18:36] <K`zan> So I have heard, not in the least interested, I've had all the sleeze I really want :).
[03:19:07] <K`zan> Sigh...
[03:19:27] <K`zan> Gonna take a break and go fix some chow, bbl.

[04:52:21] <A-L-P-H-A> ejholmgren, if you run the liveCD, that should work fine outta the box... if you just wanted to do test... [if you were so inclined]. Otherwise you'll have to ask during the day... when the gurus are around.
[04:54:06] <ejholmgren> will do
[04:54:21] <ejholmgren> have a link to the iso?
[04:54:34] <A-L-P-H-A> yeah... it's at linuxcnc.org sec
[04:54:47] <ejholmgren> o

[06:20:53] <K`zan> I found my old acad13 and even the reg for it and got it installed and sorta running under wine, need to do some work on it as it isn't running right. Worse care I run <rech> windoz.
[06:28:03] <ejholmgren> time for a reboot into the live cd

[07:27:47] <A-L-P-H-A> are we having fun yet?
[07:27:49] <K`zan> damn thing will not install on xp64, sigh...
[07:27:54] <K`zan> NO, what a PITA,
[07:28:56] <K`zan> Going to have to try regular xp or install w98 on something I guess. ARGHHHHHHHHHHHHH!
[07:29:06] <A-L-P-H-A> K`zan, for get it
[07:29:44] <K`zan> Nice idea, but it has been long enough since I wrote gcode that I doubt I remember any of it :-(.
[07:29:55] <A-L-P-H-A> shelve layout work for you? that should have.
[07:29:56] <A-L-P-H-A> that's 3d

[07:30:11] <K`zan> up on wincrap atm...
[07:30:20] <K`zan> nothing to draw with here.
[07:30:38] <K`zan> paint maybe :-).
[07:31:02] <K`zan> 64 bit stuff I am startig to think (windoz anyway) is a real waste of time and $$$.

[10:59:50] <danex> Hello alex_joni
[11:03:08] <alex_joni> hi danex
[11:03:41] <danex> Just a quick report on my test of HALUI
[11:03:54] <alex_joni> shoot
[11:04:04] <danex> It worked after a little help from jepler
[11:05:04] <danex> only one item, when the emc2 is started a Message "Unexpected delay in real time
[11:05:57] <danex> I think this may be due to the install of the software
[11:08:28] <alex_joni> danex: do you have an onboard graphics chip?
[11:09:10] <alex_joni> try following this: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?TroubleShooting#RTAI_Latency_test
[11:11:13] <danex> YES, it has not had any problems so far , I will run the Latency test
[11:12:44] <danex> a sub note :After the alarm is cleared, it does not reappear till emc is started again
[11:14:19] <danex> Anyway HALUI is a great addition to EMC2
[11:19:47] <danex> Time to go to work, have a great afternoon and thanks for the help
[11:20:49] <alex_joni> it is supposed to do that
[11:20:52] <alex_joni> only report once
[11:21:08] <alex_joni> because otherwise you'll get a flood of messages, once every 25 usecs or so ;)
[11:21:17] <alex_joni> and I KNOW you can't click that fast :P
[11:21:47] <danex> Ture
[11:21:52] <danex> True
[11:21:54] <alex_joni> :)
[11:22:16] <alex_joni> danex: if you get overruns it might be bad for driving steppers
[11:22:33] <alex_joni> you _might_ get away with it, but there's no warranty for that
[11:22:57] <danex> I am using servo
[11:22:57] <alex_joni> if the RTAI latency test reports overruns, then I suggest a cheap VGA card
[11:23:07] <alex_joni> oh, then in your case it should be less sensitive
[11:23:11] <alex_joni> what board?
[11:23:27] <danex> motenc
[11:23:52] <alex_joni> ok..
[11:24:01] <danex> with old seki drives
[11:24:14] <alex_joni> old is not always bad ;)
[11:24:46] <danex> the drives work better than some new ones I tried
[11:25:01] <alex_joni> right
[11:25:44] <danex> Anyway, I have to go to work :(
[11:26:10] <alex_joni> ok, enjoy :)
[11:26:17] <danex> have a good afternoon
[11:26:20] <alex_joni> and let me know if there are problems with halui
[11:53:42] <anonimasu> hm, cad day today ^_^
[11:57:08] <alex_joni> hi anders
[12:08:35] <ValarQ> *chirp*
[12:12:06] <anonimasu> Hello, alex
[12:12:14] <anonimasu> * anonimasu throws a cookie at valarq
[12:26:32] <alex_joni> ValarQ: seems jepler started on halgui
[12:26:37] <alex_joni> and did quite a good job
[12:27:33] <ValarQ> great
[12:27:46] <ValarQ> i hope he threw away my crap first :)
[12:28:06] <alex_joni> indeed he did ;)
[12:28:23] <alex_joni> http://emergent.unpy.net/files/sandbox/hallelujah-shaped-component.png
[12:28:45] <alex_joni> http://emergent.unpy.net/files/sandbox/hallelujah5.png
[12:28:47] <ValarQ> oh, that looks very nice indeed
[12:29:34] <SWPadnos> I'm going to have to write a spec and some sample code for my GUI-helper ideas
[12:29:54] <ValarQ> the cables looks a bit like the ones i invented for crapplication (position helpwidgets)
[12:30:31] <SWPadnos> I think this is the source, not sure which version: http://emergent.unpy.net/files/sandbox/halgui.py
[12:31:55] <ValarQ> good choice to go with tkinter
[12:32:27] <SWPadnos> Jeff seems to make a lot of good choices with python ;)
[12:32:54] <ValarQ> yeah, he's my new hero :)
[12:33:13] <alex_joni> SWPadnos: hi
[12:33:25] <alex_joni> any idea of touch probe schematics somewhere?
[12:33:35] <SWPadnos> err - not really
[12:33:37] <SWPadnos> hi
[12:33:49] <alex_joni> http://www.indoor.flyer.co.uk/probe.htm
[12:33:56] <ValarQ> except for his webpage, white on white is not a good choice for text
[12:34:07] <alex_joni> I found that.. but I can't find the stuff he references at CCED
[12:34:09] <SWPadnos> I think the electronics are trivial - it's the mechanics that are important
[12:34:18] <SWPadnos> ok - that's Graham Stabler'[s page, right?
[12:34:21] <SWPadnos> -[
[12:34:23] <alex_joni> right
[12:34:30] <SWPadnos> loading
[12:34:35] <SWPadnos> yep - I've seen that one
[12:34:42] <SWPadnos> he posts a lot on CCED
[12:34:52] <SWPadnos> and does stewart platform and related things
[12:36:15] <SWPadnos> actually - there was a question on CCED or the gecko list about 8-axis control
[12:36:46] <SWPadnos> can emc actually do anything with the other two axes?
[12:36:55] <alex_joni> SWPadnos: HAL can
[12:37:06] <alex_joni> so you can probably hook something like a portal up
[12:37:14] <alex_joni> use 2 stepgens for X & X'
[12:37:18] <SWPadnos> ok, so some custom programming (or running two 4-axis motion controllers) could be used
[12:37:39] <alex_joni> right
[12:38:06] <SWPadnos> hmmm - wait, doesn't motion provide the axes?
[12:38:15] <alex_joni> it does
[12:38:16] <SWPadnos> motmod or whatever it's called
[12:38:19] <alex_joni> right
[12:38:25] <alex_joni> and it can provide up to 8 right now
[12:38:38] <SWPadnos> but there aren't position inputs for those, I thought
[12:38:43] <alex_joni> you can probably hack a custom kins
[12:38:52] <SWPadnos> ie, the controlling numbers are generated internally to motion
[12:38:53] <alex_joni> XYZABC in, j0..j7 out
[12:39:30] <SWPadnos> right. of course, the person didn't mention what they want all those axes for, so I'm not sure
[12:40:01] <SWPadnos> I was going to respons that emc has an 8-axis controller already (and can have more pretty easily), but I wasn't sure how they could be used
[12:40:20] <SWPadnos> and unfortunately, I don't have an EMC development machine right now, so I can't find out for myself :(
[12:40:38] <alex_joni> right
[12:42:19] <alex_joni> SWPadnos: what's the msg nr. for the 8 axis question?
[12:42:35] <SWPadnos> I don't know - I'm subscribed
[12:42:44] <SWPadnos> hold on - I'll get the author/date
[12:43:08] <alex_joni> no sweat
[12:43:11] <alex_joni> * alex_joni can search
[12:44:41] <SWPadnos> I'm just trying to find which group it's from now ;)
[12:45:21] <SWPadnos> ah - it's in the geckodrive group - the person wanted 8 axes from one G-Rex (which has 6 stepgens)
[12:46:05] <SWPadnos> from Bene on 9/22, "GRex newbie questions"
[12:46:37] <SWPadnos> and the response "blah blah Mach blah blah" is interesting
[12:46:40] <alex_joni> ok, I'm subscribed to that too I think
[12:47:14] <SWPadnos> the response is from Mark Vaughan
[12:48:42] <alex_joni> yeah, just read it.. thx
[12:49:21] <SWPadnos> sure
[12:49:59] <alex_joni> * alex_joni drools: http://www.renishaw.com/userfiles/media/CMM-VID-070.m1v
[12:51:51] <SWPadnos> it's too bad that you don't get any "server install" CDs when you get a pack of Ubuntu discs
[12:52:17] <alex_joni> hmmm.. really?
[12:52:23] <alex_joni> I never tried to get the CDs..
[12:54:52] <SWPadnos> you could download several thousand in the time it takes to get them, but they're nice ;)
[12:57:46] <alex_joni> depending on the download speed :D
[12:57:57] <SWPadnos> Ray is better off with shipments ;)
[13:22:35] <alex_joni> for now
[13:32:59] <anonimasu> hehe
[13:40:14] <jepler> that "smc800" looks like a weird beast. You send winding current commands (0%, 20%, 60% or 100%) for one axis at a time, using the strobe line.
[13:40:26] <anonimasu> hm
[13:42:13] <SWPadnos> he should get an SMC1500Z, the step/dir add-on card :)
[13:42:26] <jepler> nah, he should write and contribute the smc800 driver
[13:42:44] <SWPadnos> hmmm - and the 1500Z only works on the 1500 card, not the 800. oh well
[13:47:46] <anonimasu> *ponders what smc is*
[13:48:03] <SWPadnos> Stupid Marketing Company
[13:48:12] <skunkworks> anyone have a source for cheap optical encoders?
[13:48:13] <SWPadnos> or possibly Stepper Motor Controller ;)
[13:48:18] <SWPadnos> usdigital
[13:48:28] <anonimasu> hehe
[13:48:35] <anonimasu> renco ^_^
[13:49:25] <anonimasu> hm they seem to suck..
[13:50:14] <anonimasu> "smc" that is
[13:52:02] <SWPadnos> ah - the 20% setting is there for reduced holding current
[13:52:22] <SWPadnos> 60% is for half-stepping (or possibly quarter)
[13:52:46] <alex_joni> * alex_joni remebers talking to a german user about the SMC800 before
[13:53:15] <jepler> isn't the current for quarter-stepping more like1/sqrt(2) ~ 71% than 60%?
[13:53:20] <jepler> s/like1/like 1/
[13:53:20] <SWPadnos> but that'll be slow - you need 3 parport writes per cycle
[13:53:32] <SWPadnos> I think so
[13:54:06] <anonimasu> hm, it only does one axis at a time too
[13:54:07] <SWPadnos> but 60 may be close enough
[13:54:17] <SWPadnos> right - that's why the 3 writes per cycle
[13:54:25] <jepler> yeah your maximum step rate will be about 1/3 what a traditional step+direction controller takes
[13:54:28] <SWPadnos> or I suppose only one per axis that needs a step
[13:55:34] <SWPadnos> actually, other than the 3-write problem, stepgen could almost drive this
[13:55:55] <SWPadnos> it's just a different table of patterns for the step sequence
[13:58:24] <SWPadnos> hmmm - and I guess you'd need 3 sets of update functs: stepgen.x.update / parport.0.write / stepgen.y.update /parport.0.write ...
[13:59:00] <jepler> I don't think you can call parport.write more than once per thread run
[13:59:09] <SWPadnos> you should be able to
[13:59:39] <jepler> halcmd: addf parport.0.write base-thread
[13:59:39] <jepler> HAL: ERROR: function 'parport.0.write' is not reentrant
[13:59:44] <jepler> (whaver that means)
[14:00:02] <SWPadnos> hmmm - that makes little sense
[14:00:20] <SWPadnos> is it already in a different thread?
[14:00:28] <jepler> it's already in base-thread
[14:00:49] <SWPadnos> you should be able to call a function from one thread as many times as you like, but from only one thread
[14:01:03] <SWPadnos> hmmm - that may be a bug
[14:01:25] <SWPadnos> it may also be a problem with adding things with the same name to the same list ;)
[14:02:06] <alex_joni> * alex_joni goes to buy a scanner
[14:02:07] <alex_joni> later
[14:02:20] <anonimasu> later
[14:02:21] <SWPadnos> have fun (I hear some Canons are good)
[14:05:27] <SWPadnos> ok. I think that's a bug in hal_lib. it only checls to see that a non-reentrant function is unused, but not to see if it's in the same thread, which should work
[14:05:31] <SWPadnos> checks
[14:05:36] <anonimasu> bbl
[14:05:37] <anonimasu> going home
[14:10:06] <skunkworks> SWPadnos: thanks
[14:20:21] <SWPadnos> no problem. for what? (usdigital?)
[14:33:35] <skunkworks> yes
[14:33:56] <skunkworks> Father picked up some brushed servos to play with. but I really need some encoders
[14:34:11] <SWPadnos> ah
[14:34:25] <SWPadnos> USDigital seems good if you want to experiment with encoders/servos
[14:34:38] <skunkworks> (I don't have any... at all)
[14:34:48] <SWPadnos> as you go up in quality and options, they get closer to the cost of more expensive options, though they're still less
[14:34:57] <skunkworks> all our big machines are all resolver
[14:35:10] <SWPadnos> the encoders on my motors are $450 each, for direct replacements from the same company (BEI)
[14:35:54] <SWPadnos> needless to say, I was happy to get a few small motors off ebay with the same encoder, for $50 each ;)
[14:36:12] <skunkworks> nice
[15:47:51] <alex_joni> skunkworks: why bother with encoders if you have resolvers?
[15:48:08] <alex_joni> resolvers are harder to set up, but offer way better results
[15:48:12] <alex_joni> speed & accuracy
[15:48:36] <alex_joni> SWPadnos: got an HP, was pretty cheap
[15:48:49] <SWPadnos> heh - cheap != good ;)
[15:49:00] <alex_joni> 150$ or so
[15:49:01] <SWPadnos> at least, not necessarily
[15:49:07] <alex_joni> _pretty_ cheap, not CHEAP
[15:49:21] <alex_joni> there were scanners for 30$ ;)
[15:49:27] <SWPadnos> ewwww
[15:50:15] <SWPadnos> arghhh - I finally received the camera (which was supposed to be delivered on Friday), and there's no power supply!
[15:50:25] <bill20r3> boooo!
[15:50:51] <SWPadnos> yes! boo boo hisssssss
[15:51:02] <alex_joni> SWPadnos: what kind?
[15:51:06] <bill20r3> what camera?
[15:51:21] <SWPadnos> and of course, the liveCD to use it is actually a DVD, so only my laptop (slow) and my dual opteron can boot from it
[15:51:29] <SWPadnos> http://www.elphel.com
[15:51:36] <SWPadnos> cool open-source network camera
[15:51:39] <alex_joni> SWPadnos: HP ScanJet 4850 is what I've got
[15:52:05] <SWPadnos> cool. never heard of it (I haven't looked at scanners for a few years)
[15:52:17] <bill20r3> Oh man.
[15:52:18] <alex_joni> the specs are right
[15:52:26] <bill20r3> those things make me feel all tingley inside.
[15:52:34] <SWPadnos> the cameras?
[15:52:34] <bill20r3> I've been lusting after them for years.
[15:52:39] <bill20r3> yeah, the elphel cameras.
[15:53:06] <bill20r3> funny story.. years ago one of thier dev's came into the office and tried to give us one.
[15:53:10] <alex_joni> SWPadnos: http://h10010.www1.hp.com/wwpc/us/en/sm/WF05a/15179-64195-215155-298148-215155-447373.html
[15:53:13] <SWPadnos> yeah - I saw them a year or two ago, but they weren't right for my project. now, the project has changed so thery're a better fit
[15:53:17] <bill20r3> but I didn't accept it, it was too much.
[15:53:57] <SWPadnos> I think they were $1500 or so back then, for a lower esolution imager
[15:53:57] <bill20r3> we're an ISP, and we used to host thier site.
[15:54:07] <SWPadnos> the 5MP version is now ~$800
[15:54:15] <bill20r3> oh, that's a lot cheaper.
[15:54:20] <bill20r3> just the body, right? no lens?
[15:54:21] <alex_joni> I would definately buy a camera from them
[15:54:24] <alex_joni> "Opera browser may also work, Internet Explorer -- definitely does not"
[15:54:28] <SWPadnos> I just did ;)
[15:54:29] <bill20r3> what're you using it for?
[15:54:38] <alex_joni> SWPadnos: good call ;)
[15:54:46] <SWPadnos> a couple of camera array projects, plus possible machine-related tasks
[15:54:56] <SWPadnos> I may order 100 of them in a month or so :)
[15:55:11] <bill20r3> I hope they give you a good price.
[15:55:11] <SWPadnos> I'll probably help with the design of the 5MP head, or maybe jump straight to the 8MP sensor
[15:55:20] <SWPadnos> they did - I got it for free ;)
[15:55:32] <alex_joni> heh.. Axis CPU ;)
[15:55:32] <bill20r3> lucky you.
[15:55:34] <SWPadnos> I didn't expect to, but they think my projects are way cool, so they gave it to me
[15:55:36] <SWPadnos> yep
[15:55:53] <bill20r3> got any public details on your projects?
[15:55:55] <SWPadnos> the new board in under development, and uses the higher grade AXIS unit
[15:56:00] <bill20r3> * bill20r3 is intrigued.
[15:56:10] <SWPadnos> http://www.bigfreeze.com - that's the film version
[15:57:07] <SWPadnos> of course, they're stupid, since their site is entirely flash, which I hate
[15:57:28] <alex_joni> lol
[15:57:36] <alex_joni> they also have the film in quicktime format
[15:57:44] <SWPadnos> but you've probably seen some commercials or movies with effects they've done (and I may have even run the camera for some of them)
[15:57:47] <alex_joni> even more stupid :D
[15:58:03] <SWPadnos> yeah - gotta love the motion picture industry
[15:58:03] <bill20r3> flashtastic
[15:58:34] <SWPadnos> unfortunately, I can't see how cool it is, since I have no power supply
[15:58:42] <bill20r3> this site totally fails my 10-second test.
[15:58:58] <bill20r3> after 10 seconds of looking, I still didn't know what they do.
[15:58:59] <SWPadnos> I'm considering getting one of these to remedy the problem: http://www.newegg.com/Product/Product.asp?item=N82E16833124080
[15:59:17] <SWPadnos> you have to click on the little orange squares to see anything
[15:59:30] <SWPadnos> along the left side
[15:59:40] <SWPadnos> oops - white squares until you mouse over them
[15:59:50] <bill20r3> yeah, I found those.
[15:59:58] <bill20r3> but there's no text anywhere.
[15:59:59] <SWPadnos> go to video clips, then you get orange squares along the top
[15:59:59] <alex_joni> SWPadnos: only 1 Gbit?
[16:00:10] <SWPadnos> I know - it's a "visual thing" (morons)
[16:00:27] <bill20r3> designers designing for other designers.
[16:00:47] <SWPadnos> the demo reel is cool, and the second one in (Heineken) is pretty cool as well (that was a fun one)
[16:01:06] <SWPadnos> 1gbit should be enough for 8x 100mbit ports, no/
[16:01:08] <SWPadnos> >
[16:01:09] <SWPadnos> ?
[16:01:53] <alex_joni> is the camera only 100Mbit ?
[16:01:58] <SWPadnos> yes
[16:02:04] <alex_joni> then it's ok ;)
[16:02:08] <SWPadnos> heh
[16:02:10] <alex_joni> more or less, but not for 8 cameras
[16:02:39] <SWPadnos> why not for 8 cameras?
[16:03:07] <jepler> hahahaah you should get this instead: http://www.newegg.com/Product/Product.asp?Item=N82E16833342001
[16:03:12] <SWPadnos> actually, they should think about GbE for the next version. the 5MP and 8MP sensors can generate 144MB of data per second
[16:03:31] <SWPadnos> d00d! the killer NIC r0xx0rz!!!
[16:03:59] <SWPadnos> I've actually seen reviews that say it helps, to the tune of 3-20 FPS increases in some games
[16:04:20] <jepler> that's very surprising
[16:04:24] <SWPadnos> the neat thing about that is that it's a (slow) Linux PC on a PCI card
[16:04:30] <SWPadnos> I agree, I think it's bogus
[16:04:36] <jepler> so you've heard of this thing?
[16:04:42] <SWPadnos> if it were $39, I might get one for the cool factor
[16:04:45] <SWPadnos> yep
[16:04:54] <SWPadnos> there's a long thread on a forum I frequent
[16:05:23] <alex_joni> jepler: it's not surprising at all
[16:05:45] <alex_joni> quite a few of the 'modern' network cards let the processor do quite a bit of processing
[16:05:51] <SWPadnos> it's surprising because they're claiming those speed increases over DSL/cable connections, not LAN
[16:06:01] <alex_joni> I've seen quite good systems with 60% CPU load while transferring on LAN
[16:06:11] <alex_joni> SWPadnos: that's bull
[16:06:17] <cradek> "an fps boost in almost every online game ive tried so far."
[16:06:20] <SWPadnos> sure, when transferring at close to line capacity
[16:06:31] <alex_joni> SWPadnos: likewise the guy that said he had better latency over satellite
[16:06:37] <SWPadnos> but any non-realtek GbE chip offloads most of the processing anyway
[16:06:41] <SWPadnos> right
[16:06:45] <alex_joni> "Lets see here.... It reduced a satellite internet's ping. How many products can do that?...
[16:06:48] <alex_joni> LOL
[16:06:50] <alex_joni> "
[16:07:00] <SWPadnos> that's what I was referring to - from 800 ms down to 25
[16:07:22] <SWPadnos> of course, the satellite bounce time is longer than that, unless this card also changes the laws of physics
[16:08:19] <alex_joni> it uses hiper active micro wave in the lower ultra spectrum, thus allowing the radio waves to become lightwaves and travel faster
[16:08:31] <SWPadnos> sub-space radio
[16:08:50] <alex_joni> riight.. and you can even get data from Pathfinder faster with it
[16:09:15] <SWPadnos> oh yeah - the voyager ping time was reduced from 50 hours to 37 ms
[16:09:28] <SWPadnos> round trip
[16:09:39] <alex_joni> with ECC sent twice ;)
[16:09:45] <SWPadnos> using ssh
[16:10:18] <jepler> ssh makes every byte better
[16:10:29] <alex_joni> harder to corrupt
[16:10:52] <SWPadnos> some people were speculating that the card is so fast because they strip off lots of extraneous header information
[16:11:06] <SWPadnos> which is just dumb, IMP
[16:11:08] <SWPadnos> IMO
[16:12:10] <alex_joni> SWPadnos: it makes games talk only level 1
[16:12:20] <alex_joni> no need for extra levels of encoding the data ;)
[16:12:22] <SWPadnos> MAC this, MAC that ... ;)
[16:12:33] <alex_joni> 'zactly
[16:12:46] <skunkworks> alex_joni: what circuit would you recomend for interfacing the resolver?
[16:12:56] <alex_joni> skunkworks: we have it part of the servo
[16:13:05] <alex_joni> because usually it takes care of switching too
[16:13:08] <alex_joni> AC motors
[16:13:23] <SWPadnos> there's actually a resolver interface chip, though I don't remember the company that makes it
[16:13:39] <alex_joni> but it's a pita for homebuilt.. encoders are easier to interface ;)
[16:14:09] <skunkworks> (I know I can get a chip from digikey that converts a resolver to a encoder output for I think 17 dollars)
[16:14:23] <skunkworks> quadurature
[16:14:55] <alex_joni> http://www.rtdusa.com/NEW_manuals/hardware/utilitymodules/ERES104.pdf
[16:16:35] <alex_joni> that would be a nice board for emc2 ;)
[16:16:42] <SWPadnos> http://www.analog.com/en/subCat/0,2879,760%255F791%255F0%255F%255F0%255F,00.html
[16:16:48] <alex_joni> I see the driver won't be very hard to write ;)
[16:17:42] <alex_joni> SWPadnos: yeah, but you lose position with tat
[16:17:45] <alex_joni> that
[16:18:04] <alex_joni> the main advantage of resolvers is that you always know where you are inside a rotation
[16:18:11] <SWPadnos> how so? the parallel output versions should be an absolute fraction of a revolution
[16:18:14] <skunkworks> http://www.analog.com/en/prod/0,,760_791_AD2S1200%2C00.html
[16:18:21] <skunkworks> that was the one I was looking at I think
[16:18:53] <alex_joni> SWPadnos: thought it's only quadrature
[16:19:05] <SWPadnos> nope - that one has both, actually
[16:19:22] <SWPadnos> they have some 16-bit ones as well (no quadrature output) - $43.20 minimum
[16:19:29] <alex_joni> then it's OK ;)
[16:19:50] <alex_joni> I use 10-bit / rev usually
[16:20:42] <SWPadnos> it looks like the 1200 is $21 at DigiKey
[16:20:52] <SWPadnos> it may be better to get samples from AD, even if they cahrge for them
[16:22:20] <anonimasu> :)
[16:23:56] <alex_joni> http://dsplabs.utt.ro/~juve/blog/index.cgi/photography/01159170410
[16:24:03] <skunkworks> (I was actually looking at using the converter to convert the "accupins" on our big mill to quaduture output.
[16:27:12] <SWPadnos> hey alex - are you going to Germany this week or next?
[16:27:25] <skunkworks> I was talking to JonE and he was excided about those chips - he said you used to have to buy 3 or more support chips to do what this one does.
[16:27:38] <alex_joni> SWPadnos: next week probably
[16:27:47] <SWPadnos> yeah - and then fiddle with analog electronics
[16:27:51] <alex_joni> SWPadnos: you?
[16:27:55] <SWPadnos> ah. I'll be there this weekend
[16:28:02] <alex_joni> oh.. too bad :(
[16:28:05] <SWPadnos> arriving Thursady, leaving Monday
[16:28:07] <alex_joni> seems I'll miss you :/
[16:28:15] <alex_joni> same here, but next week probably
[16:28:19] <SWPadnos> oh well. there's always next year's Fest ;)
[16:28:38] <alex_joni> mmmh, right
[16:28:49] <SWPadnos> time to apply for those Visas, huh?
[16:28:53] <skunkworks> its coming faster than you think ;)
[16:28:58] <SWPadnos> or start convincing the GF ;)
[16:29:17] <alex_joni> SWPadnos: looking for an architect right now :/
[16:30:12] <alex_joni> hi ray
[16:30:23] <rayh> hi alex
[16:30:56] <alex_joni> how's stuff?
[16:31:19] <rayh> good
[16:31:25] <SWPadnos> hi Ray
[16:31:35] <SWPadnos> alex: building a house?
[16:31:35] <alex_joni> rayh: glad to hear that
[16:31:40] <alex_joni> SWPadnos: sort of
[16:31:57] <rayh> Hi Steven
[16:35:11] <skunkworks> alex_joni: Kids room?
[16:35:13] <skunkworks> :)
[16:35:18] <alex_joni> skunkworks: hopefully not :P
[16:35:23] <alex_joni> not yet at least
[16:35:32] <SWPadnos> or "Alex's play room" ;)
[16:35:48] <alex_joni> SWPadnos: sounds more like it :P
[16:35:55] <alex_joni> actually converting an attic into a home
[16:36:13] <A-L-P-H-A> hello everyone
[16:36:20] <alex_joni> hi A-L-P-H-A
[16:37:02] <skunkworks> How is the machine moving?
[16:37:09] <A-L-P-H-A> machine moves well.
[16:37:35] <A-L-P-H-A> windows died on my workstation, and I'm too pissed at it to fix it... some isapnp.sys driver or something went missing.
[16:37:41] <A-L-P-H-A> stupid windows
[16:37:54] <alex_joni> indeed
[16:41:34] <A-L-P-H-A> does anyone think that a built 3 axis (gecko g201) working power supply, with breakout board for $600CDN (app $525USD) is okay? Comes with gecko's, heat sinks, breakout board, fuses/fuses holders etc... essentially everything, except a power switch and case.
[16:41:47] <A-L-P-H-A> I'm selling it to a buddy at that price.
[16:42:09] <alex_joni> sounds like a deal
[16:42:37] <A-L-P-H-A> I think I'm going to upgrade then to the gecko G212
[16:42:44] <skunkworks> is there a wiki page on how to setup your emc2 directory in your user dir?
[16:42:56] <A-L-P-H-A> skunkworks: I figured that one out all by myself
[16:43:02] <A-L-P-H-A> change the hal file you'r using
[16:43:08] <A-L-P-H-A> in there, there's a prefix dir.
[16:43:20] <A-L-P-H-A> change it to "~" and that will be your home dir.
[16:43:24] <skunkworks> so did I but someone is asking why he can't change the files on cnczone
[16:43:26] <A-L-P-H-A> I have a folder called
[16:43:29] <A-L-P-H-A> ~/gcode
[16:43:41] <A-L-P-H-A> and used that as my prefi
[16:43:43] <A-L-P-H-A> prefix
[16:43:54] <cradek> skunkworks: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?CustomizingConfigsOnUbuntu
[16:44:27] <skunkworks> cradek: thank you - exactly what I wanted
[16:44:49] <A-L-P-H-A> I somehow really don't like CNC zone... I don't know why.
[16:45:19] <cradek> I appreciate that skunkworks is the emc support guy there, so I don't have to
[16:46:09] <A-L-P-H-A> hahaha
[16:46:18] <alex_joni> same here
[16:46:28] <alex_joni> way to go samco :P
[16:46:36] <A-L-P-H-A> 'samco'?
[16:46:43] <alex_joni> his nick in the forum ;)
[16:46:49] <skunkworks> np - but I don't hit everything. I like it just because there isn't anything similar.
[16:46:51] <A-L-P-H-A> I see.
[16:46:57] <skunkworks> :)
[16:47:08] <alex_joni> skunkworks: there is cncecke.de ;)
[16:47:09] <skunkworks> I have many aliasas
[16:47:12] <alex_joni> but it's in german :P
[16:47:16] <alex_joni> so I need to do that myself
[16:47:50] <skunkworks> I usually just pont them to the irc channel ;)
[16:47:53] <A-L-P-H-A> 279MB in 9m13s. no bad.
[16:47:56] <skunkworks> point I mean
[16:47:57] <A-L-P-H-A> updating ubuntu...
[16:48:31] <skunkworks> sounds about right :) the live cd had those updates (except for a few)
[16:48:48] <A-L-P-H-A> nono... this is edgy... this is my workstation.
[16:48:57] <alex_joni> A-L-P-H-A: how is edgy ?
[16:49:33] <A-L-P-H-A> alex_joni: well... one thing it has working video drivers for me... dapper developers didn't want to backport the nvidia drivers... so that's why I upgrade
[16:49:43] <A-L-P-H-A> it's stable, for the most part...
[16:49:51] <A-L-P-H-A> but I really want a new windows manager.
[16:49:55] <A-L-P-H-A> gnome kind bites.
[16:50:16] <alex_joni> try xubuntu?
[16:50:22] <SWPadnos> or kubuntu
[16:50:27] <A-L-P-H-A> I don't like kde.
[16:50:31] <SWPadnos> no - you need edubuntu
[16:50:32] <A-L-P-H-A> don't know what x is... xfce?
[16:50:34] <alex_joni> eek.. kde
[16:50:34] <SWPadnos> yep
[16:50:39] <alex_joni> xfce4
[16:50:58] <A-L-P-H-A> yeah, I think it was xfce4... maybe I'll switch managers.
[16:51:00] <SWPadnos> you should be able to run WindowMaker or FVWM on ubuntu
[16:51:11] <A-L-P-H-A> FVWM was the other one I saw
[16:51:27] <A-L-P-H-A> I wouldn't mind something that was COOL and fast.
[16:51:49] <A-L-P-H-A> and a taskbar that told me what was on what monitor.
[16:52:09] <alex_joni> IceWM sounds cool enough
[16:52:14] <A-L-P-H-A> cause having 3 monitors, and a single task bar docked to a single edge of one monitor is not enough taskbar space.
[16:52:46] <cradek> the newest nvidia driver (from nvidia, not packaged by ubuntu) does install properly in the new /usr/lib/xorg scheme now
[16:53:41] <SWPadnos> the latest fvwm does pretty well with the desktop pager, according to some review I read recently
[16:53:51] <SWPadnos> and it even looks nice, with whatever this add-on package was
[16:53:58] <alex_joni> anyone knows what the man page for C functions is?
[16:53:58] <A-L-P-H-A> cradek: well... didn't help at the time, when 17xx drivers were crashing every few hours.
[16:54:01] <skunkworks> cradek: does it paly well with realtime?
[16:54:10] <jepler> skunkworks: ha ha ha
[16:54:18] <skunkworks> sorry ;)
[16:54:22] <SWPadnos> alex - install gcc-doc, and you should be able to do things like "man printf"
[16:55:01] <cradek> skunkworks: no
[16:55:05] <alex_joni> SWPadnos: ty
[16:55:27] <SWPadnos> no problem (I hope I remembered correctly ;) )
[16:55:41] <alex_joni> man strncmp
[16:55:41] <alex_joni> No manual entry for strncmp
[16:55:52] <jepler> you'll have to type "man 3 printf" because there's a useless page in section 1
[16:55:56] <A-L-P-H-A> vmware is now FREE as in BEER, but not as in speech right?
[16:56:08] <cradek> A-L-P-H-A: yes
[16:56:17] <jepler> apt-file indicates that the printf manpage is in "manpages-dev"
[16:56:36] <jepler> "apt-file search strncmp.3"
[16:56:39] <A-L-P-H-A> linux base, VMware -> windows... so I can have my autocad... I'm way to fimiliar with autocad.
[16:56:58] <alex_joni> jepler: thx
[17:28:51] <alex_joni> hi Jymmm
[17:29:01] <alex_joni> Jymmm: http://dsplabs.utt.ro/~juve/blog/index.cgi/photography/01159170410
[17:35:44] <Jymmm> Could you re-shoot this one by chance? I think it has a LOT of potential
[17:36:12] <Jymmm> same here ---> http://dsplabs.utt.ro/~juve/blog/index.cgi-files/photography/01159170410/IMG_7842.JPG
[17:36:24] <Jymmm> http://dsplabs.utt.ro/~juve/blog/index.cgi-files/photography/01159170410/IMG_7845.JPG
[17:37:37] <Jymmm> alex_joni: Maybe turn off the flash and set on tripod.
[17:38:33] <Jymmm> alex_joni: They look great though!!!
[17:38:49] <alex_joni> Jymmm: I had one without flash
[17:38:55] <alex_joni> but it was way too bright outside
[17:39:33] <alex_joni> and I didn't have my tripod with me ;)
[17:39:42] <Jymmm> no excuse
[17:40:29] <Jymmm> you could have made one out of a broom stick, 3 sticks of gum and a horseshoe
[17:40:39] <Jymmm> =)
[17:40:58] <alex_joni> mcgyver style :)
[17:45:09] <SWPadnos> MacGyver wouldn't need the horseshoe
[17:45:53] <skunkworks> I love the visa commercial with mcgyver. Very funny.
[17:46:15] <Jymmm> * Jymmm lol @ SWPadnos
[17:46:40] <skunkworks> a pen, old sock, paperclip - 13 dollars.
[17:47:50] <Jymmm> alex_joni: That's a good pic of you ---> http://dsplabs.utt.ro/~juve/blog/index.cgi-files/photography/01159170410/IMG_8231.JPG
[17:48:42] <alex_joni> Jymmm: gotta tell my gf that ;)
[17:48:50] <skunkworks> alex_joni: you look a little like my brother in law
[17:49:01] <alex_joni> I hope that's not bad :)
[17:49:05] <skunkworks> nope
[17:49:51] <Jymmm> alex_joni: Heh, blow it up to 8x10 zooming in, then make like 30 prints and stick it all over her stuff.
[17:49:54] <Jymmm> the ceiling
[17:49:57] <Jymmm> the walls
[17:50:02] <Jymmm> her car, etc
[17:50:25] <Jymmm> under her pillow
[17:50:33] <SWPadnos> in her underwear
[17:50:54] <alex_joni> Jymmm: she lives with me
[17:51:03] <Jymmm> alex_joni and your point is?
[17:51:05] <alex_joni> I wouldn't stand seeing my sorry face all over the place (lol)
[17:51:20] <Jymmm> go for it anyway, might be fun
[17:51:30] <alex_joni> I'll keep it in mind ;)
[17:51:37] <Jymmm> like hell you will
[17:51:55] <SWPadnos> no - he's too smart for that
[17:52:05] <Jymmm> the thought probably already left you mind and is half way to Brazil by now
[17:52:25] <SWPadnos> halfway to Mars
[17:54:23] <alex_joni> Jymmm: unlikely ;)
[18:12:32] <cradek> http://dsplabs.utt.ro/~juve/blog/index.cgi-files/photography/01159170410/IMG_8069.JPG
[18:13:11] <SWPadnos> desperado Alex ;)
[18:15:30] <pier_casa> alex_joni: ... che figo!
[18:17:26] <alex_joni> yee haa
[18:17:28] <alex_joni> LOL
[18:17:40] <alex_joni> that's actually my gf's hat ;)
[18:17:52] <SWPadnos> desperado Alex's GF
[18:18:03] <SWPadnos> with Alex cross-dressing for the occasion
[18:18:20] <alex_joni> indeed

[19:19:51] <A-L-P-H-A> what windows manager are you all using?
[19:20:09] <pier_casa> A-L-P-H-A: WMaker
[19:20:37] <A-L-P-H-A> how does one even choose a windows manager?
[19:20:46] <A-L-P-H-A> what features does one have over others?
[19:21:12] <pier_casa> I switched to wmaker bcause it's very light
[19:21:26] <pier_casa> starts in a sec
[19:21:35] <A-L-P-H-A> ohhh... I like that.
[19:21:49] <pier_casa> pretty customizable
[19:21:52] <cradek> I think icewm and wmaker are the good ones
[19:22:03] <cradek> I quit using wmaker becuase firefox has a bug that fights with it
[19:22:04] <A-L-P-H-A> cradek: how do I switch?
[19:22:17] <cradek> depends on your setup
[19:22:19] <A-L-P-H-A> I can't live without firefox
[19:22:21] <A-L-P-H-A> ubuntu.
[19:22:31] <pier_casa> cradek: really... ff never crashed here..
[19:22:34] <cradek> you can put whatever you want in .xsession and it will run at startup (unless your login manager does something else)
[19:22:36] <A-L-P-H-A> ubuntu edgy
[19:22:41] <cradek> pier_casa: maybe it's fixed
[19:22:56] <pier_casa> cradek: ah .. ok
[19:23:17] <pier_casa> once had problems with xscreensaver
[19:23:30] <pier_casa> I had to disable iperball
[19:24:24] <pier_casa> It got the pc stuck... I couldn't reboot it clean way even from the net
[19:24:46] <pier_casa> perhaps it's the ati driver
[19:25:07] <A-L-P-H-A> I'm chaniging to icewm
[19:25:49] <A-L-P-H-A> argh... some python bugs.
[19:26:11] <alex_joni> A-L-P-H-A: http://timeguy.com/cradek/01139948018
[19:26:15] <A-L-P-H-A> damn it... my system is like bloated with all this crap.
[19:26:23] <pier_casa> A-L-P-H-A: is that like blackbox?
[19:27:11] <cradek> that lets you run some gnome stuff still - it might be better to run no gnome depending on what you want
[19:27:38] <A-L-P-H-A> alex_joni: thanks
[19:27:59] <alex_joni> A-L-P-H-A: that's cradek's site.. no need to thank me for ;)
[19:28:11] <A-L-P-H-A> I'm debating on flushing this linux partition, and starting with 6.06.1 LTS again... instead of edgy.
[19:28:17] <anonimasu> xfce is nice :)
[19:28:25] <A-L-P-H-A> the nVidia drivers are supposedly fixed.
[19:28:26] <anonimasu> fvwm2 is even nicer ;)
[19:28:47] <A-L-P-H-A> anonimasu: , is fvwm2 the one with annoying 3d effects?
[19:29:18] <anonimasu> haha
[19:29:21] <anonimasu> no
[19:29:29] <jepler> it has beveled windows
[19:29:30] <jepler> just like motif
[19:29:49] <anonimasu> depends if you want them..
[19:29:51] <jepler> is that what you mean by "annyoing 3d effects"?
[19:30:09] <anonimasu> I ran it before long time.. though im running xfce now
[19:30:14] <A-L-P-H-A> no... the wobbly windows, and 3d cube spinner thing
[19:30:21] <anonimasu> eh?
[19:30:26] <anonimasu> * anonimasu rolls over
[19:30:30] <cradek> jellovision?
[19:30:35] <pier_casa> xgl?
[19:30:39] <alex_joni> A-L-P-H-A: that's XGl
[19:30:39] <A-L-P-H-A> xgl
[19:30:47] <alex_joni> you need compiz for that
[19:30:48] <cradek> does edgy have that by default?
[19:30:56] <A-L-P-H-A> no
[19:30:59] <A-L-P-H-A> not by default
[19:31:01] <anonimasu> brb
[19:31:02] <A-L-P-H-A> gladly.
[19:31:03] <cradek> oh good
[19:31:05] <alex_joni> cradek: no, it only works on some drivers
[19:31:11] <alex_joni> like NVidia & ATI
[19:31:19] <alex_joni> but only the accelerated ones
[19:31:39] <A-L-P-H-A> man... I think I'm going to reinstall drake in a few minutes.
[19:31:55] <pier_casa> alex_joni: my radeon refused to get it to work :(
[19:32:07] <alex_joni> pier_casa: too bad.. but I won't whine over that
[19:32:08] <alex_joni> bbl
[19:32:12] <cradek> it's cute for about five minutes
[19:32:35] <pier_casa> then u get a terrible head ache
[19:33:31] <pier_casa> don't know if buying again an Ati woud be advisable....next time
[19:35:15] <jepler> my laptop has an ATI chipset .. the opengl doesn't work quite right when textures are used :(
[19:35:42] <jepler> (with the open source driver, at least)
[19:36:06] <pier_casa> apropo... I would be grateful if anyone would give me some suggestion on the code I was working on...Take into account that I am not a professional
[19:36:11] <pier_casa> http://unirc.eu/~pier/webpage/software/dxf2G.tgz
[19:36:21] <pier_casa> jepler: I need to start x twice
[19:36:34] <pier_casa> before getting rendering working
[19:36:46] <pier_casa> ker 2.6.15.2
[19:36:52] <jepler> odd
[19:37:14] <pier_casa> but with ker 2.6.17 there's no need for that
[19:37:47] <jepler> pier_casa: long round(float f);
[19:37:58] <jepler> pier_casa: this is absolutely wrong. you should just #include <math.h> instead
[19:37:59] <pier_casa> hehe
[19:38:12] <pier_casa> it is still to be corrected
[19:38:15] <jepler> I would be amazed if the result of round() is ever right!
[19:38:34] <pier_casa> now it's no longer needed
[19:39:04] <pier_casa> having a look
[19:40:02] <pier_casa> the code is bloated with stuff coming from dos version
[19:40:12] <pier_casa> that needs removing
[19:41:50] <pier_casa> jepler: I do not remember why I put that there.... I am getting long in the tooth
[19:46:49] <jepler> hmm odd
[19:47:15] <jepler> this program gives a warning on ubuntu:
[19:47:17] <jepler> #include <math.h>
[19:47:17] <jepler> int main(void) {
[19:47:17] <jepler> return round(3.14159)-3;
[19:47:17] <jepler> }
[19:47:46] <K`zan> float main(void) {
[19:48:01] <cradek> isn't round(3.14)-3 a double?
[19:48:03] <jepler> the error is
[19:48:03] <jepler> r.c:4: warning: incompatible implicit declaration of built-in function 'round'
[19:48:12] <jepler> because round isn't in the <math.h> header file
[19:48:22] <cradek> oh really
[19:48:22] <K`zan> what does round() return?
[19:48:26] <jepler> a double
[19:48:50] <cradek> the manpage says to use -std=c99 for some reason
[19:49:16] <jepler> 'round' is new in c99? that's news to me
[19:49:56] <K`zan> really :-)
[19:52:48] <pier_casa> jepler: should I remove that declaration?
[19:53:32] <pier_casa> it is no longer used... it wouldn't hurt
[19:54:11] <A-L-P-H-A> I must be stressed or something, my skin complexion is going to shit.
[19:54:40] <K`zan> It is that lack of sunshine and raw bitter dry cold up there :-).
[19:54:48] <jepler> oh -- you also provide round() yourself
[19:55:02] <jepler> I hadn't read that far
[19:55:19] <K`zan> I should have caught that...
[19:55:19] <pier_casa> yes... to round to the nearest integer
[19:55:23] <A-L-P-H-A> hey K4ts
[19:55:28] <K4ts> hi
[19:55:38] <A-L-P-H-A> where's G-man?
[19:55:48] <K4ts> bho
[19:55:56] <A-L-P-H-A> why do I keep thinking it's gweido?
[19:56:16] <K4ts> I dont no!
[19:56:26] <A-L-P-H-A> okay. :)
[19:56:42] <K4ts> how are you'
[19:56:47] <A-L-P-H-A> something to machine... something to machine... what do I need...
[19:56:51] <A-L-P-H-A> I'm doing good...
[19:56:58] <K4ts> well
[19:57:16] <A-L-P-H-A> hmm... either play with the milling machine, or reisntall ubuntu dapper.
[19:58:56] <K`zan> * K`zan measures the dovetail width AGAIN, sigh...
[19:59:49] <jepler> pier_casa: how long should I expect the program to run?
[20:00:18] <jepler> on the example.dxf
[20:01:02] <pier_casa> seconds
[20:01:49] <K4ts> pier sei italiano?
[20:02:02] <pier_casa> si ciao
[20:02:18] <K4ts> wow finalmente
[20:02:20] <K4ts> un italiano
[20:02:33] <K4ts> di dove?
[20:02:41] <pier_casa> Lanciano
[20:02:59] <pier_casa> jepler: did it did the work?
[20:03:12] <pier_casa> do
[20:04:32] <pier_casa> you have to type return several times... shame on me
[20:05:13] <K4ts> ok I go to sleep byeeeeeee
[20:05:28] <pier_casa> notte
[20:05:32] <K4ts> hi
[20:05:37] <K4ts> ciao pier
[20:05:39] <K4ts> notte
[20:05:49] <pier_casa> ciao
[20:05:52] <K4ts> hi A-L-P-H-A
[20:06:31] <pier_casa> jepler: I'll have to remeve several "wait for a keypressed" routines
[20:08:49] <A-L-P-H-A> fun... it xchat crashed on me
[20:08:53] <A-L-P-H-A> logger_aj: bookmark
[20:08:53] <A-L-P-H-A> See http://81.196.65.201/irc/irc.freenode.net:6667/emc/2006-09-25#T20-08-53
[20:13:49] <jepler> pier_casa: oh! yes, it continued after I hit enter...
[20:14:00] <pier_casa> so sorry
[20:14:09] <pier_casa> ashes on my head
[20:14:45] <SWPadnos> is that the result of too much "Sunshine on my Shoulders"
[20:17:07] <jepler> pier_casa: is it deliberate that the lines of the two passes don't quite line up?
[20:17:26] <jepler> particularly on some of the arcs .. the radius is different by a tiny amount
[20:17:41] <pier_casa> line up? I'll have a look
[20:17:58] <jepler> I ran it this way: ./dxf2G -n 2 -p 2.5 -d 6 -i 3.5 -v 300 -u m -f example.dxf
[20:18:31] <jepler> the arcs in output lines 533 and 508 have slightly different diameters
[20:18:41] <pier_casa> yes ... I can see it on axis
[20:18:53] <jepler> r-0.81465 and r-0.82545
[20:19:25] <jepler> and the x coordinates are a bit different too
[20:19:27] <pier_casa> cause I'll have still to remove the amount of calculus no longer needed...
[20:19:38] <pier_casa> but that will disappear
[20:19:53] <pier_casa> thanks for pointing that out
[20:21:02] <jepler> that's the only problem I see with the g-code, but I've only looked at it in preview
[20:21:24] <jepler> of course cutting two passes of the circuit board makes no sense, but that's because of my options I guess
[20:21:43] <pier_casa> once the stuff regarding the old code is removed all that would be sorted out
[20:22:21] <pier_casa> it was just a tey... I use multiple passages to cut thick plywood..
[20:22:24] <pier_casa> try
[20:22:43] <pier_casa> I think it could come in handy...
[20:23:29] <jepler> I agree it's handy sometimes
[21:10:09] <danex> Hello alex_joni
[21:11:39] <danex> The latency test I spoke with you about shows in the normal range
[21:12:53] <alex_joni> do you get any overruns?
[21:13:04] <alex_joni> on the far right there's a column for overruns
[21:13:38] <alex_joni> try starting the latency test, then really stress the computer
[21:13:49] <alex_joni> maximize windows, transfer files, etc
[21:14:28] <cradek> run some GL apps
[21:15:26] <alex_joni> hi chris, still around?
[21:15:35] <cradek> for just a bit
[21:15:42] <danex> I ran programs , while accessing as400 thru emulation and viewed part prints, still no over run
[21:15:57] <alex_joni> danex: sounds kinda ok
[21:16:14] <alex_joni> however, when you start emc2 you get the warning that there was a large delay?
[21:16:55] <cradek> when you get that, the measurements are put in dmesg
[21:17:05] <cradek> so you can see how bad it is
[21:17:07] <danex> The only difference I find is the handling of M1xx codes (Between Released and Head)
[21:17:55] <danex> Yes, but no information is put into the dmsg file
[21:18:02] <cradek> yes it is
[21:18:32] <danex> when I go to the file and open it, it is blank?
[21:18:42] <cradek> run dmesg in a shell
[21:18:46] <alex_joni> danex: it's not a file
[21:18:56] <alex_joni> you run 'dmesg' from a shell, like a command
[21:19:00] <alex_joni> well.. it is a command ;)
[21:19:17] <skunkworks> is this a period issue? updated recently?
[21:19:43] <danex> My mistake, A file with the a similar name is put into the home directory
[21:19:44] <alex_joni> skunkworks: jmk/cradek recently added the means to check for overruns
[21:20:02] <skunkworks> cool
[21:20:11] <pier_casa> night all
[21:20:38] <danex> I will check this in the morning
[21:22:03] <danex> I should point out that this occurs only when running the Head version
[21:22:12] <cradek> danex: that message almost certainly means you have a hardware problem that makes your machine incompatible with realtime
[21:22:25] <cradek> yes, the test is only in head
[21:22:45] <cradek> you will have equal problems with both versions, but in 2.0.x they will be silently ignored
[21:24:06] <danex> Would I notice a problem in the function of the machine? in the release version
[21:24:25] <alex_joni> danex: it might glitch enough to miss a step
[21:24:26] <cradek> probably yes. the information in dmesg will tell us how bad the problem is.
[21:24:42] <alex_joni> danex: if you notice that or not.. it depends
[21:24:50] <alex_joni> sometimes it glitches enough for the machine to stall
[21:24:55] <cradek> the mazak had a problem like this, and it made a loud banging noise as the servos tried to briefly stop
[21:25:02] <alex_joni> eeek
[21:25:41] <cradek> danex: it may just be a bios setting or video card problem
[21:25:56] <cradek> the mazak machine was fixed simply by putting in a pci video card
[21:26:04] <alex_joni> cradek: usually those show up in the rtai latency test too..
[21:26:12] <cradek> yes
[21:26:20] <danex> video card would be no problem to add
[21:26:29] <alex_joni> danex: if you can, do it anyways
[21:26:40] <danex> O K
[21:26:47] <skunkworks> I think it did show up in the latency test - didn't it? on the mazak?
[21:27:40] <danex> On the M1xx codes should they work the same in both versions?
[21:27:40] <alex_joni> skunkworks: not on danex's machine
[21:27:43] <cradek> yes
[21:27:45] <alex_joni> danex: yes
[21:28:17] <danex> I am getting different results in the Head version
[21:28:43] <cradek> what different results?
[21:29:43] <cradek> my yes above was to skunkworks's question
[21:29:56] <danex> In The release version an example is I set a Signal True it remains true Till I set it false with another M- code
[21:31:00] <danex> In the Head version I set the signal true, It remains true till the program advances to the next line
[21:31:39] <danex> then returns to false
[21:32:52] <alex_joni> danex: how do you set it true?
[21:33:42] <danex> halcmd sets true
[21:34:04] <alex_joni> any & on the end of that?
[21:34:33] <danex> no
[21:35:10] <danex> I have the signal name in of course
[21:35:42] <alex_joni> odd
[21:35:51] <alex_joni> are you sure the signal doesn't have any other writers?
[21:36:42] <rayh> * rayh is really worried by this discussion. Something about needing a task planner comes to mind.
[21:37:07] <danex> No other writers It only closes a contactor
[21:39:00] <danex> When installing the Head version(Running in place), is it required to have the release version also installed ?
[21:39:33] <alex_joni> danex: no
[21:39:44] <alex_joni> and running 'halcmd sets .. true' might cause problems
[21:39:50] <alex_joni> e.g. activating the wrong halcmd
[21:40:04] <alex_joni> you need to specify the full path to halcmd to make sure you get the right one
[21:40:28] <alex_joni> e.g. /home/danex/emc2-head/bin/halcmd sets .. true
[21:40:45] <danex> So for a really good test, I could install the Head version on a seperate HD ?
[21:41:22] <alex_joni> danex: shouldn't be necessary.. just put the full path in there
[21:41:49] <danex> I'll try that
[21:43:00] <danex> I found a graphics card , ATI Rage, any known problems with this type?
[21:45:26] <jepler> I've used a similar card, it's fine.
[21:47:52] <danex> A question on the install of the Head Version, I saw that axis is now a part of EMC2, Is it still required to get the build-dep emc2-axis?
[21:48:38] <jepler> short answer: yes
[21:49:12] <jepler> long answer: "apt-get build dep" installs the packages necessary to rebuild the package version. The CVS version may have different build requirements than the packaged version.
[21:51:17] <alex_joni> danex: so once 2.1.x is out, you can safely use apt-get build-dep emc2
[21:51:34] <alex_joni> but until then, you need to either run build-dep for emc2 & emc2-axis
[21:51:50] <alex_joni> or open the emc2/debian/rules file, and install all the needed packages
[21:52:00] <jepler> I think you mean debian/control
[21:52:14] <alex_joni> control even
[21:52:14] <alex_joni> right
[21:52:24] <alex_joni> Build-Depends: debhelper (>> 4.0.0),linux-headers-2.6.12-magma,g++,gcc-3.4,make,libc6-dev,tcl8.4-dev,tk8.4-dev,libgtk2.0-dev,pciutils-dev,libncurses-dev,gettext,libxaw7-dev,rtai-modules-2.6.12-magma,libreadline5-dev,lyx,lyx-qt,python,tetex-bin,latex2html,yapps2
[21:53:14] <danex> I reconize the "yapps2" from the install dialog
[21:54:29] <jepler> yapps2 is required if you want to use 'comp': http://linuxcnc.org/docs/devel/html/hal/comp/
[22:00:42] <alex_joni> can someone verify (at least by looking at it): http://pastebin.ca/182280
[22:01:56] <jepler> it probably breaks AXIS...
[22:02:59] <jepler> you should probably use the <math.h> M_PI instead of your own PIl
[22:03:41] <jepler> #define INCH_MM (1/25.4) might be clearer .. hm, and it's not equal to the value you give
[22:03:52] <alex_joni> it was the value from the ini
[22:03:56] <alex_joni> that's why I chose it
[22:04:19] <alex_joni> I was reluctant in including rtapi_math.h, does math.h provide M_PI ?
[22:04:22] <jepler> you may not have intended to include the change to gridprobe
[22:04:30] <alex_joni> jepler: I won't commit that ;)
[22:04:37] <jepler> you can include <math.h> if it's a userspace program, no problems there
[22:04:42] <alex_joni> but it's in there to remind you of optional stop :P
[22:04:43] <danex> This gives me some reading and some interesting tests for tomorrow, Thanks to All of You and have a good night
[22:04:50] <jepler> good night danex
[22:04:56] <alex_joni> night danex
[22:05:18] <alex_joni> 25.4 is an approximation afaik
[22:05:32] <fenn> 1/25.4 == .0393700787401574803
[22:05:32] <jepler> no, I think it's the exact value
[22:05:37] <jepler> the inch was redefined to be 25.4 mm
[22:05:42] <fenn> yep
[22:06:14] <fenn> 1/25.4 is better
[22:06:17] <jepler> see units.dat "The US Metric Law of 1866 ..."
[22:06:33] <alex_joni> ok
[22:06:34] <jepler> "since [1959], the foot has been exactly 0.3048 meters"
[22:07:02] <alex_joni> 1/25.4 looks way better anyways
[22:07:28] <fenn> i think you should change it to .0393700787401574803149606299212598425196850393700787401574803149606\

[22:08:05] <fenn> for the sake of accuracy
[22:08:10] <alex_joni> :P
[22:08:14] <jepler> /kick fenn
[22:08:18] <alex_joni> you missed a couple of decimals
[22:08:21] <alex_joni> jepler: should I?
[22:08:24] <jepler> nah
[22:08:28] <alex_joni> :))
[22:08:30] <alex_joni> kidding
[22:09:01] <fenn> will old ini files still work with the new system?
[22:09:37] <jepler> alex_joni: if you check that in, please also update http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingConfigurationsForDevelopmentVersions
[22:10:06] <alex_joni> jepler: it's compatible
[22:10:13] <alex_joni> aka old ini still work
[22:10:19] <jepler> alex_joni: but eventually we want to get rid of the old code, don't we?
[22:10:41] <jepler> we should recommend people change it even if it will still work during the 2.1 series.
[22:10:48] <alex_joni> however you can have an ini with only [TRAJ] LINEAR_UNITS = inch and [TRAJ] ANGULAR_UNITS = degree
[22:11:14] <alex_joni> jepler: I think having the functionality in place (to be able to define one axis differently can't hurt..) maybe not have it in the docs ;)
[22:11:37] <alex_joni> we'll see.. for 2.1 I'd like people to know they can live without that
[22:15:18] <A-L-P-H-A> that nap was whacked.
[22:18:46] <jepler> The English word inch comes from Latin uncia meaning "one twelfth part" (in this case, one twelfth of a foot); the word ounce (one twelfth of a troy pound) has the same origin.
[22:18:56] <jepler> </wikipedia>
[22:21:51] <alex_joni> hmm.. did you know google has an calculator?
[22:21:56] <A-L-P-H-A> yes
[22:21:57] <alex_joni> seems similar to units: http://www.google.com/intl/en/help/features.html#calculator
[22:22:03] <A-L-P-H-A> alex_joni: , also has a dictionary
[22:22:07] <A-L-P-H-A> "define: inch"
[22:23:22] <alex_joni> * alex_joni added 'in' to the list of linear units
[22:23:31] <alex_joni> "The international standard symbol for inch is in (see ISO 31-1, Annex A)."
[22:26:37] <alex_joni> I always knew it was insane what's going on with different measurements.. but there are _way_ too many standards
[22:26:42] <alex_joni> http://en.wikipedia.org/wiki/Cubit
[22:27:25] <alex_joni> http://en.wikipedia.org/wiki/List_of_strange_units_of_measurement
[22:27:42] <A-L-P-H-A> alex_joni: cradek: jepler: what wm do you guys use again? gnome is annoying me.
[22:28:33] <A-L-P-H-A> wonder could we all just stick with SI units?
[22:28:42] <A-L-P-H-A> just to piss off the yanks
[22:29:12] <A-L-P-H-A> i think cradek uses icewm
[22:29:33] <alex_joni> A-L-P-H-A: indeed, cradek uses icewm
[22:29:45] <alex_joni> * alex_joni always has used metric systems
[22:29:58] <A-L-P-H-A> I switch from either... I'm weird.
[22:31:18] <alex_joni> ROFLMAO: defines 1 Lovelace as "...the amount of force (measured in dynes) it takes to draw a round ball weighing e Troy Ounces (84.548 g) down a tube it fits exactly (in air) at a speed of pi attoparsecs/microfortnight (0.080148 m/s)."
[22:32:09] <bill20r3> hah
[22:32:21] <skunkworks> didn't you know that?
[22:32:23] <alex_joni> named after a pr0n movie
[22:34:19] <alex_joni> bet you don't know what a yobibyte is
[22:34:54] <alex_joni> "The yobibyte is closely related to the yottabyte, however, it is also known as a blockabyte which is incredibly indubitably undoubtedly megapixel gigatronic exponentially languishing hardcore megapixel, which can either be a synonym for yobibyte, or refer to 1024 bytes = 1,000,000,000,000,000,000,000,000 bytes, depending on context"
[22:35:04] <bill20r3> it's a byte, divided by a yobi
[22:36:13] <alex_joni> http://en.wikipedia.org/wiki/Binary_prefix <- quite closer than you think to a byte

[22:44:38] <alex_joni> jepler: I know I should probably not do this:
[22:45:03] <alex_joni> when I start AXIS, and run 3D_Chips, all is ok, until I switch to metric view (from the menu)
[22:45:15] <alex_joni> when I do that, the tool size gets converted to very small
[22:47:53] <alex_joni> jepler: and using 'inch' in the ini does break AXIS.. should I still commit ?

[23:15:05] <robin_sz> alex_joni, wow ... no more UNITS=0.03793030303303003030 for inches?
[23:17:48] <alex_joni> robin_sz: indeed
[23:17:48] <CIA-8> 03alex_joni 07HEAD * 10emc2/configs/sim/tkemc.ini: sample ini with LINEAR_UNITS=inch
[23:18:47] <robin_sz> alex_joni, that bugged me for AGES .. I had several shouting matches with a certain other developer over that one
[23:19:04] <robin_sz> kudos dood.
[23:22:17] <alex_joni> Kudos means tissue in Finnish.
[23:22:46] <alex_joni> ;-)
[23:29:11] <robin_sz> heh
[23:30:13] <robin_sz> whatever, it always bugged me that it was worng .. you should use words or numbers to select from alist "1 for inches, 2 for mm" or whatever, not 0.037392929393838
[23:30:58] <rayh> but that doesn't work for angstroms or lightyears unless you add those units.
[23:31:18] <robin_sz> so what ... it never worked for those before
[23:31:25] <rayh> sure it did.
[23:31:32] <alex_joni> rayh: right
[23:31:37] <alex_joni> but adding them is trivial
[23:31:37] <robin_sz> you only had two choices ... 0.037373737373737 or whatever it was
[23:31:43] <robin_sz> or mm
[23:31:49] <alex_joni> robin_sz: no, you could actually put a value there ;)
[23:31:51] <alex_joni> and it got used
[23:31:56] <rayh> No you could put any multiplier there that you wanted.
[23:32:13] <alex_joni> robin_sz: it probably was OK about 90% of the places
[23:32:36] <rayh> I really dislike the shrinking ability that I seem to be seeing these days.
[23:32:44] <alex_joni> shrinking?
[23:32:49] <robin_sz> certainly last I looked t the code, emc days, it was "if foo = 0.039393938383838 then scale = inches else scale =mm) in at least a few places
[23:33:02] <alex_joni> robin_sz: I think that's gone
[23:33:09] <robin_sz> get it on decimal place out and .. voom, mm
[23:33:39] <robin_sz> it would be trivial to implememntn both and have the best of all worlds
[23:33:50] <robin_sz> UNITS=12.499595
[23:33:53] <robin_sz> or
[23:34:05] <robin_sz> LINEAR_UNITS=wombat
[23:34:12] <alex_joni> robin_sz: that's how it works now
[23:34:19] <robin_sz> a wombat being 12.49995
[23:34:21] <robin_sz> right
[23:34:26] <robin_sz> so nothing lost at all then
[23:34:45] <alex_joni> the [TRAJ] LINEAR & ANGULAR_UNITS _can_ hold names
[23:34:53] <alex_joni> it can also hold numbers as before
[23:34:58] <robin_sz> so, no shrinking ability then
[23:35:10] <robin_sz> thats nice
[23:35:16] <alex_joni> the [AXIS_*] UNITS _can_ be missing, but if there it overrides the [TRAJ] one
[23:35:48] <robin_sz> nice
[23:36:10] <alex_joni> * alex_joni is still trying hard to imagine a case where someone might want different units on different axes
[23:36:45] <robin_sz> it would be nice to set them upin diofferent units .. eg if you had one metric and one imperial leadscrew
[23:36:56] <robin_sz> keep the numbers nice
[23:37:32] <rayh> It would be a pretty odd machine.
[23:37:37] <alex_joni> robin_sz: anything wrong with 157.480 vs. 4000 ?
[23:37:50] <alex_joni> anyways.. it is possible
[23:37:54] <robin_sz> right
[23:38:05] <robin_sz> rayh, dumpster divers build odd machines
[23:38:26] <alex_joni> ebay brings all sort of things together;)
[23:38:28] <rayh> Sure but you can always define input scale regardless of what the pitch of the screws is.
[23:38:38] <alex_joni> it's easy nowadays to mix&place mm with inches
[23:38:43] <alex_joni> rayh: right
[23:38:49] <robin_sz> sure
[23:38:55] <alex_joni> so no real reason for that..
[23:39:12] <rayh> I can't imagine wanting to x2(inch) y19(mm) however.
[23:39:21] <robin_sz> anyway .. our linear encoder fun continues ... jmks suggestion for magentising the tapes worked OK
[23:39:23] <alex_joni> nah.. that's not possible
[23:39:38] <alex_joni> rayh: you can't mix inside G-code
[23:39:55] <robin_sz> just in the axis set up
[23:40:13] <rayh> Didn't say I wanted to...<g>
[23:40:17] <alex_joni> rayh: re adding new: I think it's quite easy to add a new one:
[23:40:18] <alex_joni> http://cvs.linuxcnc.org/cvs/emc2/src/emc/nml_intf/emcglb.h.diff?r1=1.6;r2=1.7;f=h
[23:41:08] <robin_sz> gah, missing an angular unit there .. ;)
[23:41:46] <alex_joni> which one?
[23:41:54] <robin_sz> mils :)
[23:42:02] <alex_joni> that's not angular.. is it?
[23:42:06] <robin_sz> Ionce bought a compass and the sodding thing was in mils
[23:42:13] <robin_sz> yeah ...
[23:42:21] <alex_joni> mils = inch / 1000 ?
[23:42:37] <jepler> what if I want my angular units in seconds of a degree? Then I'd specify angular feed rate in seconds per minute...
[23:43:34] <alex_joni> jepler: lol
[23:43:38] <alex_joni> 60 ?
[23:43:42] <rayh> Is it possible now to use a float for input scale?
[23:43:49] <alex_joni> rayh: it is
[23:44:08] <rayh> Good cause the Smithy machine uses a float.
[23:44:21] <alex_joni> "During World War II the U. S. Army often used a mil equal to 1/1000 of a right angle, 0.1 grad, 0.09°, or 5.4 arcminutes (often written 5.4 moa; see "moa" below). More recently, various NATO armies have used a mil equal to 1/1600 right angle, or 0.05625° (3.375 moa). In target shooting, the mil is often understood to mean 0.001 radian or 1 milliradian, which is about 0.0573° or 3.43775 moa. In Britain, the term angular mil generally refers to the milliradian.
[23:45:23] <alex_joni> I'm updating some docs.. and I am wondering
[23:45:37] <alex_joni> is MAX_FEED_OVERRIDE really a [DISPLAY] setting?
[23:45:38] <rayh> Wah. Now I think I'll stick to decimal fractions of degrees per minute.
[23:45:39] <robin_sz> There are 2000×pi milliradians in a circle. So a milliradian is just over 1/6283 of a circle. Each of the definitions of the angular mil are similar to that value but are easier to divide into many parts.
[23:45:39] <robin_sz> * 1/6400 of a circle in NATO countries.
[23:45:39] <robin_sz> * 1/6000 of a circle in the Soviet Union and Finland.
[23:45:39] <robin_sz> * 1/6300 of a circle in Sweden. The Swedish term for this is streck, literally "line". Sweden has not been part of NATO nor the Warsaw Pact
[23:45:52] <alex_joni> or should it really be in [TRAJ] ß
[23:45:53] <alex_joni> ?
[23:46:01] <rayh> It's used for the endpoint of the override slider.
[23:46:08] <robin_sz> wahetver .. ignore that, mils are not used in engineering, just in maps
[23:46:21] <alex_joni> rayh: yes, but it influences the machine speed a lot
[23:46:36] <robin_sz> still, trust the daft and barmy to come up with their own crazy angular units :)
[23:46:52] <alex_joni> rayh: actually I'm wondering more about min&max_spindle_override
[23:47:12] <alex_joni> which should probably be in [IO], but I put them along with max_feed_override
[23:47:42] <rayh> Scale changes the accel time but does it for all axes so not traj change.
[23:48:12] <rayh> Until we begin to squirrel with corner rounding.
[23:48:23] <alex_joni> well.. I guess it's true based upon what you understand for TRAJ
[23:48:30] <alex_joni> if it's only the path, then I agree
[23:49:32] <CIA-8> 03alex_joni 07HEAD * 10emc2/docs/src/config/ini_config.lyx: updated docs for LINEAR_UNITS=inch change
[23:50:05] <robin_sz> * robin_sz wonders if anyone uses grads at all ever
[23:50:17] <alex_joni> SWPadnos wanted that explicitely :)
[23:51:40] <robin_sz> coo
[23:51:45] <robin_sz> oh, its a french thing
[23:51:48] <robin_sz> apparently
[23:52:03] <alex_joni> sounds like a good thing for steppers
[23:52:10] <alex_joni> those are usually 400 steps / rev ;)
[23:52:39] <robin_sz> right .. getting close to bedtime ...
[23:52:53] <rayh> I don't know whether scale will change the radius of arcs in g64
[23:53:16] <alex_joni> rayh: it can under certain conditions cause changes to the path
[23:53:44] <robin_sz> whatever, we think we have it down to less than $50 for a 3m linear encoder, so the weekend was time well spent
[23:53:44] <alex_joni> but I think we should leave it that way
[23:54:18] <rayh> Okay. Then add the min and max spindle there as well?
[23:54:33] <alex_joni> they are there..
[23:54:40] <alex_joni> but it somehow seems .. wrong
[23:54:58] <robin_sz> right bedtime
[23:55:26] <SWPadnos> hey wait - I didn't want grads, I just thought the system should support them ;)
[23:55:38] <alex_joni> SWPadnos: now you have to use them :P
[23:55:43] <SWPadnos> oh noes
[23:56:04] <alex_joni> anyone knows how a checkbox looks like in tcl/tk?
[23:56:24] <SWPadnos> [x] or [ ]
[23:56:26] <SWPadnos> ;)
[23:56:29] <alex_joni> lol
