[00:00:07] <i_tom> moved cargo with dragging sledges
[00:01:12] <i_tom> gentlemen, anyone of you built a custom cnc panel ? with all the controls, DRO, display and etc ?
[00:01:38] <i_tom> I mean from scratch ?
[00:01:58] <i_tom> I have some concerns mounting my LCDs
[00:04:17] -!- someone972 [someone972!~someone97@71-218-195-29.hlrn.qwest.net] has joined #linuxcnc
[00:05:58] <nlancaster> i have not built one of thoseyet. but I have done a few things with LCDs. what kind of convern?
[00:11:42] <i_tom> I bought a couple of LCD panels on eBay
[00:11:47] <i_tom> they look and work great
[00:11:59] <i_tom> but are really thin 2.5 mm
[00:12:11] <i_tom> and is really hard to figure out how to mount them securely
[00:12:38] <i_tom> they only came with double stick tape on the front bezel, which is not really a bezel
[00:12:46] <nlancaster> there are screw holes in the edge of hte frame
[00:12:52] <i_tom> no,
[00:12:55] <nlancaster> ussualy
[00:12:58] <i_tom> unfortunately none of them
[00:13:29] <i_tom> I was thinking, mayme sticking it ot a plate of aluminum about 5 mm thick
[00:13:36] <i_tom> on* a plate
[00:13:38] <nlancaster> should work
[00:13:46] <nlancaster> they do have a metal frame round the outside right?
[00:13:59] <i_tom> with small pocket on the other side to mount some acrylic screen
[00:14:03] <CaptHindsight> with touchscreens?
[00:14:05] <i_tom> 2 mm thickness
[00:14:11] <i_tom> I'm guessing
[00:14:25] <i_tom> No, at the moment I haven't bought touch screen for the panel
[00:14:27] -!- bedah has quit [Quit: Ex-Chat]
[00:14:36] <CaptHindsight> what size are these?
[00:14:44] <i_tom> It would be an option though
[00:14:47] <nlancaster> why not clamp along the edges of the screens, with a piece of thin foam in between
[00:14:47] <i_tom> 10.1"
[00:14:56] <nlancaster> that is one way I have seen them mounted
[00:16:01] <i_tom> I don't actually want to mount them permanently. Wanna think of some way to be assembled and to have option of replacing the acrylic protective screen.
[00:16:12] <nlancaster> that is what I am talking about
[00:16:35] <nlancaster> not double tape or naything. just use calmping to hold the entire sandwitch together.
[00:16:48] <i_tom> I got it now, sorry, when I read "foam" I thought of stick foam
[00:17:03] <nlancaster> the foam is just to give a bit of padding to the clamp
[00:17:04] <i_tom> and yes, that with the foam and clamp would be a great choice
[00:17:07] <nlancaster> keep from over tightening it
[00:17:15] -!- skorasaurus has quit [Ping timeout: 272 seconds]
[00:17:34] <i_tom> and on the other side you're right, clamping metal to glass directly is not very good idea

[00:20:48] <i_tom> check this out http://www.ebay.co.uk/itm/10-1inch-B101EW05-1280-800-lcd-panel-HDMI-VGA-2AV-Reversing-lcd-Driver-board-/181044271659?pt=UK_Computing_Laptop_Screens_LCD_Panels&hash=item2a27145a2b
[00:20:52] <i_tom> it's the same model
[00:22:20] <i_tom> mine has a bit higher resolution 1920x1200

[00:36:03] <andypugh> nlancaster: Sorry, I was elsewhere. I was suggesting that your statement was very obvious :-)
[00:36:37] <andypugh> Pole lathes still work extremely well.
[00:37:06] <andypugh> (For wood mainly, but metal is do-able)
[00:38:13] <someone972> Whats a typical acceleration limit and velocity limit for a stepper based machine?
[00:38:33] <someone972> Just for some caculations, not an actual machine
[00:39:04] <nlancaster> ah, np andypugh
[00:39:17] <andypugh> You might like this: https://www.youtube.com/watch?v=wnv0DAR_gWA
[00:39:33] <andypugh> someone972: Metric or Imperial?
[00:39:50] <someone972> Imperial I suppose
[00:39:59] <andypugh> No idea then :-)
[00:40:09] <someone972> Metric works too, i'll just convert it :P
[00:40:31] <andypugh> Try 30mm/sec and 600mm/sec/se
[00:41:49] <someone972> I guess I'll round those to 1 inch/sec and 24 inch/sec/sec to make it easier, thanks
[00:41:56] <andypugh> Interestingly the _ratios_ between the numbers are very different in Imperial.

[00:42:54] <andypugh> (It doesn't seem like they should be)
[00:43:18] <nlancaster> woodwrights shop he uses and also shows how to build several different lathes.
[00:43:35] <nlancaster> no special tools required. just wood, but onceyou have a wood lathe, you could work up from there.
[00:46:01] <nlancaster> http://youtu.be/DD_PBkV7Ovg
[00:53:54] <RyanS> , which is a good engineering supplier in the UK? like the equivalent of MSC, McMaster.. Everything is a rip-off in Australia
[00:54:18] <someone972> Does linux cnc use a certain unit internally? I see this line 'tiny_dp = max_dv * period * 0.001' which would change by a factor of almost 25 if inches were given to it instead of mm.
[00:55:10] <andypugh> someone972: LinuxCNC is metric Internally. However the Axis UI is inches internally. (<shrug>)
[00:55:53] <someone972> So if I'm doing calculations in inches I should convert any constants to inches first then.
[00:57:45] <andypugh> RyanS: I get a lot of stuff from RS (who also exist in Aus). Never cheapest, but good for stock and delivery. Other than that I use Cromwell tools, as I am 10 minutes walk from one, but they have a proper range of stuff: https://www.cromwell.co.uk
[00:58:16] <andypugh> However, really, anything you might want, at any qulaity level, is probably on eBay now.

[01:03:12] <Mr_Mayhem> andypugh Those engine parts look beautiful by the way.
[01:03:32] <RyanS> yeh, RS is expensive but quick. I was always wondering what sort of quality their RS generic brand is
[01:03:42] <andypugh> Yeah, Roger is the sort of perfectionist I wish I was.
[01:04:17] <andypugh> I probably need to share this link here too. It was a really good TV series, http://youtu.be/QisKUt_fPPU

[01:05:38] -!- asdfasd has quit [Ping timeout: 264 seconds]
[01:05:49] <RyanS> shipping to Australia from the UK seems a lot cheaper than from the US (although exactly the same if you useDHL)
[01:07:02] <andypugh> Maybe we have the same queen on the stamps?
[01:08:04] <RyanS> That's probably it.. I think U.S. Postal Service is just really expensive
[01:09:11] <RyanS> Chinese post is so slow you forget that you ordered something when it arrives
[01:09:19] <eric_unterhausen> it's like santa
[01:09:41] <andypugh> Yeah, packages arrive and I have no idea what they are going to be :-)
[01:09:59] <andypugh> it's rather fun.
[01:10:30] <CaptHindsight> the last administration tried to bankrupt the USPS by requiring them to prefund their pension plans for something ~30 years
[01:11:05] <CaptHindsight> thats why rates are so high
[01:11:43] <CaptHindsight> it was a plan designed to bankrupt the USPS so that it could be replaced by private firms
[01:11:50] <RyanS> we thought we got lots of parcels to our house, but the delivery guy said some people get more than five a day
[01:12:27] <PCW> USPS still much cheaper than UPS/Fedex etc
[01:12:40] <RyanS> Bricks and mortar shopping is a waste of time. Although sometimes you need to see the shit in person
[01:13:04] <eric_unterhausen> when my garage door can be controlled from the internet, I'm going to surprise the ups man when he brings a package
[01:13:36] <Mr_Mayhem> open sesame
[01:13:43] <CaptHindsight> be sure to make a video
[01:13:47] <eric_unterhausen> it cost less than $60
[01:13:56] <RyanS> not as surprised if you built a robot to receive the package
[01:15:04] <eric_unterhausen> my son left the garage door open overnight, I decided it was worth $60 to save all my stuff from some meth head

[01:15:43] <RyanS> Amazon was thinking of using drones to deliver parcels, but they were concerned about the liability if it lands on your cat
[01:15:45] <CaptHindsight> $60 for a meth box on the sidewalk?
[01:16:01] <eric_unterhausen> all the forum spammers are posting football game links
[01:16:01] <CaptHindsight> that was just a PR stunt
[01:16:03] <andypugh> I spent all of Christmas (I was away for 2 weeks) beating myself up for my OCD worrying about whether I locked the back door. came back to find the back door unlocked...
[01:16:09] -!- AR__ [AR__!~AR@] has joined #linuxcnc
[01:16:31] <RyanS> was probably just remote control
[01:16:31] <eric_unterhausen> funny
[01:16:47] <CaptHindsight> andypugh: we unlocked while you were away :)
[01:17:05] <Tom_itx> there's an ap for that
[01:17:17] <Tom_itx> but i wouldn't trust it
[01:17:23] <eric_unterhausen> I used to live on the top of a mountain and one time I stayed late at work, rode my bike home and then had to ride back to see if the door was locked

[01:17:46] <eric_unterhausen> there is an app to open my garage door
[01:17:51] <Tom_itx> andypugh next time you decide to do that let us know
[01:18:05] <Tom_itx> i could use a nice mill and a few odd tools
[01:18:07] <eric_unterhausen> we will fume your oak furniture for you
[01:18:19] <andypugh> I don't own anything worth the air fair
[01:18:31] <Tom_itx> what exactly is 'fuming' the wood?
[01:18:36] <andypugh> (And the workshop is always locked)
[01:18:37] <Tom_itx> i've not heard of that
[01:18:42] <andypugh> Ammonia
[01:18:51] <eric_unterhausen> changes the tannin in oak black
[01:19:01] <andypugh> http://en.wikipedia.org/wiki/Ammonia_fuming
[01:19:02] <RyanS> Your grandmother would probably just say back in my day it was safe to leave the doorunlocked
[01:19:04] <CaptHindsight> http://en.wikipedia.org/wiki/Ammonia_fuming
[01:19:04] <eric_unterhausen> you can make oak look like ebony if you work at it
[01:19:08] <archivist> old method of fuming was horse piss
[01:19:16] <eric_unterhausen> still works
[01:19:23] <eric_unterhausen> but nobody has horses
[01:19:35] <Tom_itx> plenty of horses arses around though
[01:19:35] <CaptHindsight> how do you get a horse to aim at your wood?
[01:19:39] -!- matheus_ has quit [Ping timeout: 260 seconds]
[01:19:41] <eric_unterhausen> but why wouldn't you just use human piss
[01:20:17] <eric_unterhausen> I suppose that the stuff from horses makes more ammonia
[01:20:30] <Tom_itx> interesting
[01:21:01] <eric_unterhausen> back when we had diaper service, they picked up once a week, you could use those things for fuming, no problem
[01:21:06] <RyanS> I always like the one about hatters using mercury as part of the process hence the phrase,
[01:21:18] <nlancaster> mad as a hatter!

[01:21:56] <RyanS> I'm always picturing an Irishman I don't know why
[01:22:06] <eric_unterhausen> we had one prof that insisted on using mercury pressure gauges, they were always in there with bunny suits
[01:22:08] <nlancaster> leprachan?
[01:22:28] <andypugh> I can't decide if I should do it or not, but I am thinking it seems like "faking" age, so I probably won't bother.
[01:23:03] <eric_unterhausen> like I said the other night, they used to do it all the time, just because it looks better
[01:23:07] -!- Komzzzpa has quit [Ping timeout: 272 seconds]
[01:23:19] <CaptHindsight> unless you prefer bleached oak
[01:23:34] <eric_unterhausen> not really to try to age it, but because the un-fumed wood looks a little under-finished
[01:24:15] <RyanS> I watched some video sword making and the guys spent hours using hand file.... I was thinking really just use an angle grinder and a flap disc
[01:24:34] <eric_unterhausen> I think most knife makers use belt grinders
[01:25:26] <andypugh> Oak is pretty enough as it comes, and it darkens naturally in a decade or so.
[01:25:34] <RyanS> Or just use plain steel and make i decorative unless you fancy yourself as a real mediaeval warrior
[01:25:50] <CaptHindsight> did anyone else have the knife sharpener guy come around with his cart with a pedal powered grinder?
[01:25:59] <eric_unterhausen> ya, just use shellac and it will be fine
[01:26:06] -!- heathmanc has quit [Ping timeout: 272 seconds]
[01:27:01] <RyanS> I bought the Diamond knives sharpening device that was made by the same manufacturer and its screwed up the knife completely
[01:28:52] <RyanS> It had like a series of dmetal fingers that you run the blade through..
[01:29:08] <andypugh> We didn't do anything with the oak here, just a rub with wax and waited 10 years. it looks nice. There is one bit in the picture (the centre vertical) with a 400-year lead on the rest. https://picasaweb.google.com/lh/photo/WGCTXkddltFILzkDZ2i-ytMTjNZETYmyPJy0liipFm0?feat=directlink

[01:30:54] <i_tom> andypugh: sorry to interrupt, pretty nice wood on the picture :)

[01:31:35] <Mr_Mayhem> hehe
[01:31:41] <Mr_Mayhem> Nice wood.
[01:31:42] <Tom_itx> andypugh is that the same one we've seen other pics of?
[01:32:09] <andypugh> The table in the foreground is Elm, and is my dad's work. I made all the doors, we both made the stairs and the roof. (You can just see the 10" x 10" oak purlins)
[01:32:15] <i_tom> it reminds me somehow of blackmore's night
[01:32:16] <i_tom> ;)
[01:32:29] <andypugh> Tom_itx: Aye, that it be.
[01:33:56] <i_tom> andypugh: a cousin of mine who is having a coffee with me by now and is a 3rd generation carpenter sends his compliments
[01:33:58] <i_tom> too
[01:34:00] <RyanS> my dad wants to renovate the kitchen..... I can't see that ending well
[01:35:11] <i_tom> RyanS: why is that
[01:35:32] <RyanS> I don't think it's worth the hassle
[01:35:43] <andypugh> Possibly worth mentioning that my dad made a forge to make the hinges and door handles you can see in that photo too. (I was bred this way, you see)
[01:36:22] <eric_unterhausen> renovating the kitchen is a horrible idea
[01:36:26] <Tom_itx> not a home depot kit home?
[01:36:27] <i_tom> Another respect then!
[01:36:42] <eric_unterhausen> renovation is the 4th leading cause of divorce in the U.S.
[01:36:50] <i_tom> omg
[01:36:56] <RyanS> I think I could understand why
[01:37:00] <eric_unterhausen> I just made that up
[01:37:09] <eric_unterhausen> but it's really not uncommon at all
[01:37:14] <RyanS> Is probably true
[01:37:22] <Mr_Mayhem> THe original do it yourself: Make a forge for the door hardware.
[01:37:26] <Mr_Mayhem> nice.
[01:37:37] <i_tom> Have a nice day, gentlemen. Good luck with the projects.
[01:37:46] <eric_unterhausen> my parents got divorced and a renovation was definitely a contributing factor
[01:37:57] <andypugh> A very old web site with the full story of that house and what we did. http://www.bodgesoc.org/slaithwaite.html
[01:38:29] <andypugh> This is a website to old that thumbnails really were, as 28k8 modems were still common

[01:38:39] <RyanS> Actually I was thinking of making one of those propane forges with fire bricks, but the idea of making the and gas burner frightens me
[01:39:30] <andypugh> RyanS: Just use coke and air. That's what they still use. It's as much about chemistry as heat
[01:40:11] <nlancaster> as part of my CNC router want. cutting patterns for casting metal.
[01:40:26] <eric_unterhausen> I'm resolved to replace my failed transaxle
[01:40:41] <nlancaster> with a DIY?
[01:40:42] <nlancaster> wow!
[01:41:02] <RyanS> I really just want to use it to bend stuff, although with casting you can really only melt aluminium unless you have a pretty serious forge?
[01:41:10] <eric_unterhausen> yeah, with a diy removed from a junk car transaxle
[01:41:20] <nlancaster> you can melt bronze
[01:41:36] <nlancaster> it is only a little higher temp then aluminum
[01:41:41] <CaptHindsight> eric_u_cnc: this weather reminds me of every time I had to swap a trans or replace a clutch in the snow
[01:41:43] <nlancaster> and Steel is possible at home, but much harder.
[01:41:59] <CaptHindsight> eric_unterhausen: ^^
[01:42:01] <andypugh> Even I was thinking that an axle from scratch was quite a project. (Though I know folk who would attempt it)
[01:42:10] <eric_unterhausen> i'm the same eric, as it happens
[01:42:24] <CaptHindsight> wasn't positive
[01:42:34] <eric_unterhausen> my major car repairs always happen when it is bitter cold
[01:42:46] <RyanS> And does it go through gas tanks really quickly? You know the ones where you cut up an old propane tank and line is with whatever
[01:43:16] <eric_unterhausen> one of my many bosses says, "nobody buys dell" and wants a microsoft surface
[01:44:37] <CaptHindsight> http://www.bodgesoc.org/Slaithwaite2/end_stairs.JPG is that bulb right over the stairs or just an illusion?

[01:45:26] <owhite> hello people.
[01:45:59] <andypugh> Really? They are planning to replace the laptops we use at work (Dell) with Toughbooks. But the Toughbooks cost 10x as much and, even though we give them a really hard time, we probably break one Dell every 5 years each, not 10. Plus the Toughbooks have tiny blurred screens, and can't charge below -20C
[01:46:30] <RyanS> eric_unterhausen were you talking about the oxygen concentrator propane set up?
[01:46:38] <andypugh> CaptHindsight: It's closer than it appears :-
[01:46:56] <eric_unterhausen> RyanS, not recently
[01:47:21] <eric_unterhausen> my boss isn't an idiot, but she plays one on tv
[01:47:52] <Mr_Mayhem> heh
[01:48:10] <owhite> I recently have tried to compile linux 2.6-pre on ubuntu using the xenomai rt kernal and I got the following error message when I ran linuxcnc http://pastebin.ca/2524565
[01:48:14] <eric_unterhausen> we bought a batch of portable workstations, and she had to have one because they were the newest laptops
[01:48:47] <CaptHindsight> andypugh: whats the electrical code for old structures like that? has to be in conduit? or?
[01:49:12] <Tom_itx> hook and loop
[01:49:16] <Tom_itx> :)
[01:49:17] <owhite> exec_prefix should be /usr/local but for some reason it's not getting set.
[01:49:20] <eric_unterhausen> owhite, when you ran that did you use rip_environment first?
[01:49:26] <eric_unterhausen> is it a run-in place build?
[01:49:41] <owhite> no, prefix=/usr/local
[01:49:55] <eric_unterhausen> it's not being substituted in
[01:50:03] <andypugh> Actually, that's a good photo, you can see the wood colour there, I have one I took of the same room last week: https://picasaweb.google.com/lh/photo/1LcbScYB4zvjXmaA7Ma5s9MTjNZETYmyPJy0liipFm0?feat=directlink
[01:50:07] <CaptHindsight> I had a house with hook and loop left in a few walls
[01:50:08] <eric_unterhausen> did you make install?
[01:50:35] <RyanS> brazing no? I'm thinking of getting an oxygen propane set up just so only need to rent oxygen.. Can't weld steel, but who cares j
[01:50:48] <eric_unterhausen> my mother's house has knob and tube wiring
[01:51:08] <eric_unterhausen> ya, you should be able to weld light steel with that
[01:51:09] <owhite> yes - I ran $ sudo make install

[01:51:33] <andypugh> CaptHindsight: The electrical code is "Don't ask, don't tell"
[01:52:09] <eric_unterhausen> if you properly installed linuxcnc, you should be able to run it from anywhere, not from linux/scripts
[01:52:22] <owhite> understood
[01:52:33] <eric_unterhausen> did you try that?
[01:52:50] <owhite> I get the same error running it from anywhere, yes.
[01:53:15] <CaptHindsight> I moved to oxygen propane a few years ago. When I went to buy propane people had left empty tanks that i was able to exchange for full and new, at 1/4 the price of getting new tanks
[01:53:20] <andypugh> RyanS: MAPP Gas is pretty good.
[01:53:46] <RyanS> I know oxygen propane is perfectly fine for cutting, but I wonder how it goes with heating and brazing duties
[01:53:52] <Tom_itx> eric_unterhausen any push button switches left in the house?
[01:54:01] <CaptHindsight> fine for brazing
[01:54:22] <RyanS> You can't get mapp in refillable cylinders. I don't think
[01:54:47] <andypugh> Ah! A question, where can I get authentic-looking 1920s/1930s push-button switches and knobs for my Rivett lathe cabinet?

[01:55:35] <owhite> eric_unterhausen: any other suggestions?
[01:56:44] <RyanS> Apparently they don't make MAPP in the formulation that was almost as powerful as acetaleye ..
[01:56:49] <andypugh> CaptHindsight: That's a very "soft" flame compared to oxy-acetylene
[01:57:17] <RyanS> It's kind of MAPP lite
[01:58:15] <CaptHindsight> Maximum neutral flame temperature of acetelyne in oxygen is about 5720*F.
[01:58:16] <CaptHindsight> Maximum neutral flame tempature of propane in oxygen is about 5112*F.
[01:58:18] <andypugh> My sister welds with electrolytic oxy-hydrogen, that's a nice short hard flame.
[01:58:39] <CaptHindsight> MAPP like all of the Liquified Petroleum gasses is not appropriate for welding of steel, due to the high concentration of hydrogen in the flame. The hydrogen infuses into the molten steel and renders the welds brittle.
[01:58:54] <eric_unterhausen> Tom_itx, I don't think so
[01:58:55] <eric_unterhausen> when I was a kid, one of my uncles had pushbuttons and I thought they were great
[01:59:15] <RyanS> How quickly do you go through oxygen. If you don't do much cutting?
[01:59:27] <eric_unterhausen> owhite, I'm refreshing my shell script programming
[01:59:43] <andypugh> CaptHindsight: I am not so moch talking about the temperature of the flame, as the size od the "point" and how much force it has for pushing about the weld pool.

[02:58:23] <RyanS> I could never understand why that didn't get through when even NRA members supported tbackground checks
[02:58:41] <theorbtwo> Not sure that's all that true. If anything happens that will make the cost of guns at retail go up for obvious reasons, you can be sure that 200% of the additional costs will be passed on to the consumer.
[02:58:42] <RyanS> The only explanation would seem to be the manufacturers have influence
[02:59:15] <theorbtwo> If you make it so that existing guns have to be disabled and made unfireable, then people will buy new guns.
[02:59:16] <CaptHindsight> bullets are in short supply

[02:59:46] <eric_unterhausen> if you are willing to ignore everything else
[03:02:37] <RyanS> I guess I just don't understand how the debate is of a series of slogans from gun lobby that seem to ignore the statistics
[03:04:03] <andypugh> The simple fact is that in countries with fewer guns, fewer people get shot.
[03:04:25] <andypugh> Whether that is good or bad is a different question,
[03:04:55] <theorbtwo> andypugh: I saw some interesting things the other day. The number of homicides don't go down terribly much as you reduce gun ownership.
[03:05:15] <theorbtwo> When guns got cracked down on hard in London, more people got killed by knives.
[03:05:16] <andypugh> I am prepared to believe that more than hallf the people who get shot are better shot than alive.

[03:23:48] <eric_unterhausen> I would have been better at using the 9mm to defend myself by using it as a hammer
[03:24:00] <eric_unterhausen> because you had to be smarter than the gun to actually get it to fire
[03:24:09] <eric_unterhausen> I don't always qualify
[03:25:44] <RyanS> Have you seen this movie with George Clooney called The American? He manufactures a silencer in a hotel room using hand tools
[03:30:42] <eric_unterhausen> yeah, I just watched that a month ago
[03:31:07] <eric_unterhausen> I didn't quite figure out if he made the gun blow up on purpose or if he was just incompetent
[03:31:43] <eric_unterhausen> if you reach into your rear pocket,and your wallet has a trigger, don't pull
[03:32:06] <RyanS> I don't remember that bit, but it reminded me of some old Frederick Forsyth novel
[03:32:26] <eric_unterhausen> he delivers the weapon, it turns out it's meant for him
[03:32:35] <eric_unterhausen> spoiler non-alert
[03:33:28] <theorbtwo> Sounds like somebody got really pissed off watching the New Yankie Workshop.
[03:33:30] <RyanS> poor George
[03:33:48] <eric_unterhausen> well, he starts out the movie by killing his girlfriend
[03:33:55] <eric_unterhausen> because he figures she ratted him out
[03:34:28] <eric_unterhausen> so I can't feel too sorry for him
[03:35:06] <RyanS> . Why do the women go after George is really quite old
[03:35:18] <eric_unterhausen> well, we know about the prostitute
[03:35:26] <eric_unterhausen> he was paying her a lot
[03:37:38] <RyanS> They use them for this luxury watch and I don't even think he is wearing it "$1 million without the watch, 2 million with the watch"
[03:37:43] <DaViruz> andypugh: i like guns :)
[03:37:50] <DaViruz> mostly for technical reasons though
[03:38:01] <RyanS> him*
[03:39:31] <DaViruz> the same way i like other technical things like engines, machine tools etc
[03:39:51] <RyanS> luxury watch commercials are like the epitome of advertising 'selling dreams'which is really like most non-essential item advertising

[03:43:00] <eric_unterhausen> I stopped wearing a watch when I got a cellphone
[03:43:52] <RyanS> More accurate as well, assuming they synchronised to timeservers
[03:44:02] <eric_unterhausen> seems to be
[03:44:27] <theorbtwo> RyanS: Most cell phones will automagically synch to a time signal they get off of the cell tower.
[03:44:31] <R2E4> I lose my cell phone as much as I did my watches
[03:44:57] <theorbtwo> ...sadly, dispite having an extremely accurate clock internally to maintain frequency, they have horrible time signals.
[03:45:24] <theorbtwo> Why? I have no clue.

[06:00:40] <R2E4> The plc has 45 relays on it.
[06:01:13] <eric_unterhausen> do you have a schematic?
[06:01:34] <eric_unterhausen> the moore at work has relays driving relays
[06:01:34] <R2E4> I need to buy a boatload of relays but thats going to cost.

[06:02:40] <R2E4> I have a dl06
[06:02:44] <eric_unterhausen> for whatever reason, the schematics with relays drive me crazy
[06:02:53] <R2E4> and the ZIP I/O expansion
[06:03:14] -!- Fox_Muldr has quit [Ping timeout: 264 seconds]
[06:03:44] <R2E4> IT has a 20 position ATC on it.Cant figure that one out yet
[06:03:57] <eric_unterhausen> those things are magic
[06:04:08] <eric_unterhausen> the people that made it probably barely understood it
[06:04:15] <eric_unterhausen> "ship it!"
[06:04:22] <R2E4> The three axis I dont think I'll have a problem with but the spindle servo and the ATC.....
[06:04:30] <R2E4> Dont know if it is going to work.
[06:04:42] <eric_unterhausen> what's so hard about the spindle servo?

[06:06:21] <R2E4> let me find it
[06:06:53] <R2E4> magnet seperator..... WTF is that?
[06:07:35] <eric_unterhausen> it's a signal?
[06:07:42] <R2E4> Theres 8 motors not including the axis servos
[06:09:33] <R2E4> ok,
[06:09:57] <R2E4> SP Forward, SP reverse, SP orientation SP low gear
[06:10:06] <R2E4> sp tool unclamp
[06:10:10] -!- someone972 has quit [Quit: irc2go]
[06:11:29] <eric_unterhausen> that's interesting, they use the magnets for clamping or something?
[06:11:30] <R2E4> looks like transistor turning on relay and its sending ground through each of those
[06:12:35] <R2E4> theres a relay to remove the z axis brake in that schematic
[06:14:09] <R2E4> ITs documented really well, problem is you cant follow anything through it with the machine wiring
[06:16:54] <R2E4> the magnet seperator is a motor
[06:17:01] -!- skorasaurus has quit [Ping timeout: 252 seconds]
[06:17:46] <R2E4> ITs a fanuc module for the spindle servo
[06:18:06] <eric_unterhausen> that's horrible
[06:18:07] <eric_unterhausen> I am not a huge fan of little number labels on wires, but it sure beats no labels
[06:18:07] <eric_unterhausen> yeah, but what do the magnets do?
[06:18:08] <eric_unterhausen> part of a brake?
[06:19:07] -!- cmorley has quit [Quit: Leaving.]
[06:19:18] <R2E4> I dont know yet
[06:20:15] <R2E4> sp speed check signal, sp certain speed signal sp zero speed signal spindle alarm orientation finish
[06:20:51] <eric_unterhausen> so it's some stuff to avoid having to do logic in the computer
[06:21:04] <R2E4> theres a cutting monitor output out of the sp servo amp
[06:21:47] <eric_unterhausen> that's cool, wonder how that works
[06:21:55] <eric_unterhausen> are they injecting a signal?
[06:22:08] <eric_unterhausen> or current monitor?
[06:22:55] <R2E4> its an output, to monitor when cutting, dont know how they would do that unless they are measuring the load
[06:23:13] <R2E4> theres a load meter and rpm meter
[06:26:11] <R2E4> I am scared I wont get the spindle servo working, the xyz axis should be no problem
[06:26:23] <R2E4> Then theres the 6 million relays
[06:26:31] <eric_unterhausen> it's possible that some of the complexity can be ignored
[06:26:58] <R2E4> Thats probable

[15:50:14] <CaptHindsight> Jymmm: the down side is the very high inrush current when the caps have discharged, the alternator will need current limiting since the inrush current can be in the 1,000's of amps if there are good clean connections between alternator and caps
[15:50:40] <Tom_itx> can someone point me to the current 2.6 git source/
[15:50:41] <Tom_itx> ?
[15:52:17] <IchGuckLive> Tom_itx: why not the buildbot
[15:52:30] <Tom_itx> because the deb isn't current
[15:52:30] <IchGuckLive> http://buildbot.linuxcnc.org/
[15:52:45] <IchGuckLive> it is stable and best to go
[15:52:58] <Tom_itx> this is for testing
[15:53:10] <IchGuckLive> master branch is from 2nd jan
[15:53:18] <IchGuckLive> so its 2 days old
[15:53:33] <Tom_itx> i tried using the deb and it's broke
[15:54:13] <CaptHindsight> ask in the dev channel
[15:54:33] <Tom_itx> i think they sleep longer than you
[15:54:34] <Tom_itx> :_
[15:55:03] <IchGuckLive> Tom_itx: for standard or xenomai
[15:55:08] <CaptHindsight> it's saturday
[15:55:21] <Tom_itx> i'm not too sure of the difference IchGuckLive
[15:55:42] <Tom_itx> probably standard
[15:55:47] <IchGuckLive> at the Realy front end there is no more ubuntu all devs are at xeno
[15:56:05] <Tom_itx> i wanted to test the new TP
[15:56:37] <Tom_itx> what linux flavor are they using?
[15:57:04] -!- kwallace has quit [Read error: Connection reset by peer]
[15:57:22] <zultron> What're you trying to do, Tom_itx ?
[15:57:41] <Tom_itx> just do some testing
[15:57:56] <Tom_itx> i wanted to test the new TP out on some hardware for them
[15:58:00] <zultron> Current 2.6 git source is always at git.linuxcnc.org
[15:58:15] <IchGuckLive> Tom_itx: git clone git://git.linuxcnc.org/git/emc2.git tomtest
[15:58:37] <IchGuckLive> git reset --hard origin/master
[15:58:49] <zultron> There you go. :)
[15:58:52] <IchGuckLive> then you are at the front end
[15:59:00] <Tom_itx> then i need to add in the new TP code
[15:59:04] <IchGuckLive> standard ubuntu
[15:59:09] <zultron> I don't think the new TP code is in master, though.
[15:59:14] <Tom_itx> no it isn't
[15:59:32] <Tom_itx> skunkworks was gonna help me install that i believe
[15:59:42] <IchGuckLive> its maybe in cradeks git
[15:59:48] <IchGuckLive> or jepplers
[15:59:52] <Tom_itx> newer than that
[16:00:43] <Tom_itx> the new trajectory planner from robert
[16:01:12] <IchGuckLive> just make a git commit an someone will fill it in the nightly
[16:01:22] <Tom_itx> http://www.youtube.com/watch?v=oUajH5BCOUQ&feature=c4-overview&list=UUHk52YjGT8HryRYmJKSl-lg
[16:01:39] <Tom_itx> looks quite promising
[16:02:44] <IchGuckLive> my simple gcoe maker pocket can do this for years
[16:03:16] <Tom_itx> the read ahead difference is what is impressive
[16:03:17] <IchGuckLive> with chexckbox start inside outside finish rouph
[16:03:31] <Tom_itx> same feed/speed
[16:04:32] <IchGuckLive> just commit it and someone will take care
[16:04:47] <Tom_itx> i'm also new to git :)
[16:05:05] <Tom_itx> always learning
[16:05:07] <Tom_itx> never stop
[16:05:41] <zultron> https://github.com/robEllenberg/linuxcnc-mirror/
[16:06:12] <zultron> That's where the new TP code is being developed. I don't know which branch he's committing to, though. :-/
[16:06:56] <zultron> But the circular-blend-arc-alpha branch was updated 2 days ago.
[16:07:03] <zultron> https://github.com/robEllenberg/linuxcnc-mirror/branches

[16:07:06] <IchGuckLive> he is committing against master 2.5.1
[16:08:52] <zultron> I don't understand? Ellenberg's work is based on either master or 2.5, yes.

[16:59:55] <Jymmm> JT-Shop: http://www.youtube.com/watch?ca7ZPfkcNqA
[17:00:19] <pcw_home> 7I77 outputs are sourcing outputs (so supply field power to the load)
[17:01:10] <R2E4__> I think they source positive side, which would suck
[17:01:30] <CaptHindsight> yes ^^
[17:01:52] <R2E4__> ok, thanks pcw, then my idea wont work
[17:03:17] <pcw_home> if you have all 12V relays, then use 12v field power
[17:03:43] <R2E4__> I have a mix of relays, 12 and 24
[17:03:57] -!- atom1 [atom1!~tom@unaffiliated/toml/x-013812] has joined #linuxcnc
[17:04:07] <pcw_home> thats awkward (and a bit odd)
[17:04:16] <R2E4__> Most of what is in the machine is 24v relays, so I will have to go with 24vdc and obtain more 24vdc relays
[17:04:58] <R2E4__> TYhe plc has around 50 relays in it
[17:05:27] <pcw_home> if you need more outputs that the 7I77 has you can add another remote I/O at another field voltage
[17:06:47] <R2E4__> ah yeah, didnt think of that. will see. I may try and keep the board with all the relays on it and cut the traces and create my own relay board using the existing relays. The plc board has all the relays soldered on it.
[17:07:39] <pcw_home> there is a sinking driver as well if that makes wiring easier (7I72)
[17:07:47] <R2E4__> I'm coming to grips with the drawings, I dont know who did them but they suck....
[17:08:17] <R2E4__> Cant match and trace from drawing to machine
[17:08:18] <eric_unterhausen> drawings always suck
[17:08:50] <pcw_home> Onsemi has a new driver chip that has eight 1/2 bridges so we may eventually have individual sink/source ability
[17:09:02] <R2E4__> The bridgeport drawings are fantastic. Every line and point has a number kkwhich is matched by number label on the wire.

[17:28:14] <R2E4__> Regular spindle PWM output of the 7i77?
[17:29:13] <pcw_home> probably OK but you may want a common mode choke on the 2 wires to keep HP noise from the spindle drive out of th other axis

[19:18:58] <owhite> hey people. I built an instance of linux on 12.04 using xenomai from the documentation found here: http://www.anderswallin.net/2012/12/linuxcnc-on-ubuntu-12-04lts/
[19:19:14] <owhite> The compile worked, the tests look good.
[19:19:42] <owhite> the compile was done with run-in-place
[19:19:57] <owhite> but I cant find an executable for linuxcnc. Any suggestions?
[19:20:57] <CaptHindsight> owhite: did you install or build linuxcnc as well?
[19:21:22] <CaptHindsight> or just build and boot a xenomai kernel?
[19:21:32] <owhite> I ran make and sudo make setuid
[19:21:57] <CaptHindsight> on what system?
[19:22:19] <CaptHindsight> there are also RTAI debs for 12.04
[19:22:35] <eric_unterhausen> my 27" monitor from woot just came in
[19:22:55] <eric_unterhausen> I think I'll install one of those evil nvidia cards and see if I like it
[19:23:05] <owhite> oh, I found some documentation saying RTAI has not been kept up to date.
[19:23:16] <CaptHindsight> yeah, thats old info
[19:23:24] <CaptHindsight> it was updated over the summer
[19:23:25] <owhite> so I used: http://www.anderswallin.net/2012/12/linuxcnc-on-ubuntu-12-04lts/
[19:24:11] <CaptHindsight> owhite: ok so you started with Ubuntu 12.04 and now have a xenomai kernel, now you have to install Linuxcnc
[19:24:12] <owhite> yeah there's a lot of out of date information for linuxcnc.
[19:24:37] <owhite> Capt: yes. I've compiled linuxcnc as well.
[19:25:21] <owhite> and ran the tests successfully described on that page.

[19:58:00] <owhite> thanks eric_unterhausen
[19:58:17] <eric_unterhausen> first answer. I've heard that they considered changing the name from grub2 to "boot obfuscater"
[19:58:35] <eric_unterhausen> but decided that was too much truth for the linux community to swallow
[19:59:05] <owhite> the reboot worked, and man do i have some nice max jitter numbers.
[19:59:22] <eric_unterhausen> do a stress test
[19:59:46] <owhite> oh yeah that. I was thinking of running six compiles while doing the latency-test :-)
[19:59:51] <eric_unterhausen> my max jitter was fine until I stressed it a little
[20:00:06] <eric_unterhausen> it turned out on my system that the best stress test was to go to utube
[20:00:31] <eric_unterhausen> someone suggested not going to utube, but that didn't work either

[20:02:06] <owhite> installing flash seems to be slowing it down pretty good too. :-)
[20:02:26] <eric_unterhausen> once I went to the vesa vid drivers, my latency was fine
[20:02:44] <eric_unterhausen> went up from the unrealistic 4000nS to about 15nS
[20:03:01] <owhite> yeah I'm getting those kind of numbers as well.
[20:03:14] <eric_unterhausen> sorry, 15uS

[20:03:45] <CaptHindsight> what cpu's and chipsets?
[20:04:09] <owhite> I have a mini-ITX running atom and I believe it's 1.8Ghz
[20:04:50] <eric_unterhausen> I have an athlon dual core 2.5ghz on an asrock 790gx
[20:05:01] <owhite> hey I'm just happy I successfully installed linuxcnc.
[20:05:14] <owhite> oh, and dont have to use liveCD.
[20:05:29] <eric_unterhausen> are you going to be using software stepping?
[20:05:40] <owhite> you mean steppers? Yes.
[20:06:18] <eric_unterhausen> you could be using steppers with a mesa or pico system too, just wondering how important latency was
[20:06:37] <owhite> I'm using a mesa.
[20:06:54] <eric_unterhausen> ok, so latency is not that important
[20:07:06] <owhite> upgrading from a pico - which I liked but I'm making a new control board for my laser.
[20:07:40] <eric_unterhausen> any reason why you didn't just go with the livecd?
[20:08:15] <owhite> the 10.04 OS didnt drive my wifi board.
[20:08:55] <owhite> and dont quote me on it but I also think it wasnt driving my display very well.
[20:09:46] <eric_unterhausen> the splash screen on ubuntu 12 is better than the 10 splash screen
[20:09:59] <eric_unterhausen> but I'm not sure about once you get into the OS
[20:10:33] <owhite> I wasnt going to mention the cosmetic stuff, but yeah the 10.04 just looks and feels downright old.
[20:12:32] <eric_unterhausen> I am not a big fan of transparent desktop objects, but I have gotten used to them
[20:13:26] <Loetmichel> owhite: hmmm
[20:13:35] <owhite> ?
[20:14:00] <Loetmichel> first thing i do when istalling a new win7: select design "windows Classic"
[20:14:11] <Loetmichel> ... i LIKE the 10.04 desktop!
[20:14:20] <eric_unterhausen> windows classic has some annoyances though
[20:14:31] <eric_unterhausen> I use an XP system and it drives me nuts
[20:14:52] <eric_unterhausen> I remember when I first got used to XP and then winNT would drive me nuts
[20:15:08] <owhite> well if we're comparing OS's let me tell ya I just became a macOS convert after 10 years of resistance.
[20:15:30] <eric_unterhausen> you can get used to anything
[20:15:43] <eric_unterhausen> I hated unity when it first showed up, but now I'm used to it
[20:15:53] <owhite> install parallels on macOS and you can run any microsoft OS you want. It's amazing.
[20:16:07] <eric_unterhausen> the fact that 10.04 would randomly lock up and 12.04 didn't was a big aspect of that

[20:23:43] <eric_unterhausen> there is so much bad information out there about video cards
[20:23:56] <eric_unterhausen> or rather, changing them on ubuntu
[20:24:13] <eric_unterhausen> I think I might just plop the new card in and hope that it works
[20:24:27] <owhite> outdated docs?
[20:25:47] <eric_unterhausen> ubuntu no longer uses xorg.conf
[20:25:59] <eric_unterhausen> it uses some obfuscated magic
[20:26:06] <Deejay> in 12.04 it does
[20:26:34] <eric_unterhausen> it can, but it doesn't unless you force it to
[20:26:55] <eric_unterhausen> for example, neither of my 12.04 systems us xorg.conf
[20:26:57] <Deejay> yep, if there is no xorg.conf, it gets the information from somewhere else
[20:27:42] <Deejay> first thing after installing was to create xorg.conf and setup everything correctly ;)
[20:27:48] <eric_unterhausen> I think that may help me in this situation
[20:27:59] <Deejay> using xorg.conf I at least know what to do ;)
[20:28:34] <eric_unterhausen> if everything goes right, it's easy to troubleshoot the new way of doing things
[20:28:57] <eric_unterhausen> of course, if everything goes right, you don't need to troubleshoot
[20:29:33] <eric_unterhausen> they have adopted the microsoft method where you can't go onto the internet to complain if the computer doesn't boot
[20:29:53] <Deejay> hrhr
[20:30:21] <eric_unterhausen> I was on a help chat session with HP service and they kept urging me to reboot
[20:30:44] <eric_unterhausen> of course, at that point I would be disconnected from them, so it would not count against their statistics

[22:00:33] <Tom_itx> someone suggested it was for 2.5
[22:00:37] <andypugh> It's all the same archive, just checkout v2.5_branch
[22:00:55] <Tom_itx> ok, i'm still learning git as well but i think i can do that
[22:01:13] <Tom_itx> i did get 2.6 compiled and ran it
[22:01:35] <andypugh> "git checkout v2.5_branch" will probably automatically create a new tracking branch and switch to it, as i accidentally found out earlier

[22:25:40] * uw waits
[22:26:01] <andypugh> Meduza: It's generally better to not use a switched PSU. The right transformer, rectifier and caps wil tend to be tougher and better for the load (you don't really need good regulation)
[22:26:46] <andypugh> A switched high frequency supply and a switched high frequency load can (I have heard) sometimes not play well together
[22:28:46] -!- uw has quit [Quit: Leaving]
[22:29:05] <Meduza> i have used switched supplys both with leadshine DM drivers and allegro based ones with no problem
[22:29:55] <Meduza> even if i added a large capacitor just to be sure when using higher current
[22:30:50] <Meduza> the question is more about how sensitive the Toshiba drivers are
[22:33:12] <Meduza> is the 50v max claims correct or is it a spec too much on the limit
[22:33:34] <Jymmm> ...and does it include BEMF too?
[22:34:33] <Meduza> so will a 48v supply blow the drivers at the first time the motors brake or will it work fine

[22:35:53] <skunkworks> from that point - you build it as you would master
[22:35:58] <Meduza> i have tried the tb6560 before and they were quite sensitive. thought someone in here would have tried the newer higher power tb6600
[22:36:24] <Meduza> so i didn't had to blow one :)

[22:36:31] <atom1> skunkworks, do i put it in the same directory as master?

[23:51:34] <andypugh> Ah, OK, then start from scratch
[23:52:07] <andypugh> You can still use a matrix keyboard and a 7i73 if that suits you
[23:52:11] <eric_unterhausen> haas has a lot of buttons too, don't really see the need
[23:52:58] <R2E4__> I need more i/o which is important. Havent figured out which card I am going to use to connect to 7i77
[23:56:03] <andypugh> You can also wire a matrix KB to GPIO using the matrix_kb HAL component which can be a lot more economical than wiring each button directly. (for example, an 8x8 matrix is 16 HAL pins and 64 buttons). Note that the buttons don't have to be physically in a matrix, they just need to be wired that way
[23:56:45] <eric_unterhausen> the moore control we have has 8 buttons, more than enough
[23:56:51] <R2E4__> thats a good idea.
