[00:00:07] <PetefromTn_> works for me ;)
[00:00:10] <malcom2073> If I didn't have to work, I'd be so stinkin busy
[00:00:18] <andypugh> Tom_itx: In this case, lazy and independent
[00:00:19] <PetefromTn_> me too LOL
[00:00:28] <PetefromTn_> I would be doing all sorts of useless shit
[00:00:44] <PetefromTn_> and lots of fishing in exotic places
[00:01:15] <andypugh> I would be buying exotic places and banning fishing there :-)
[00:01:38] <PetefromTn_> who are you hitler?
[00:01:43] <PetefromTn_> hehehe
[00:01:53] -!- asdfasd has quit [Ping timeout: 276 seconds]
[00:03:31] <andypugh> I have quite a lot in common with Hitler: European, white, facial hair, short.
[00:03:46] <jdh> do you speak german?
[00:04:06] <andypugh> Nein.
[00:04:07] <PetefromTn_> they say he only had one ball too...:D
[00:04:17] <_methods> one big ball
[00:04:31] <PetefromTn_> hehehe one big freaking EVIL HAIR BALL
[00:05:29] <PetefromTn_> my wife is making me some black bean soup/chili with cheese,sour creme and chips tonight. One of my favorite cheap meals
[00:05:32] <andypugh> Oh, another point of commonality: Have been known to snog germans
[00:05:41] <PetefromTn_> snog?
[00:06:07] <PetefromTn_> is that one of those quirky brit terms?
[00:06:29] <andypugh> So it seems
[00:07:03] <PetefromTn_> had to look that one up
[00:07:04] <_methods> http://motherboard.vice.com/read/will-this-fancy-metallic-glue-kill-soldering
[00:08:14] <CaptHindsight> when can we just beating editors to death for posting articles like that?
[00:08:25] <_methods> mesoglue
[00:09:00] <_methods> mesohungry
[00:09:38] <malcom2073> Hah the first line: "If you want to piss off ****** engineer, tell them the future of their field is <isnert news article here>"
[00:10:17] <andypugh> Now _this_ is a cool use of tech: http://motherboard.vice.com/read/smart-spoon-helps-parkinsons-patients-feed-themselves
[00:10:18] <_methods> i'll still just solder stuff for the hell of it if solder is ever made obsolete
[00:10:55] <_methods> there is something therapeutic about soldering stuff
[00:11:10] <CaptHindsight> I dare you to find even more expensive and toxic materials to replace solder, I dare you.... mesoglue
[00:11:30] <PetefromTn_> kinda reminds me of Tig welding
[00:11:31] <_methods> heheh
[00:11:42] <_methods> yeah welding is the same
[00:11:44] <malcom2073> Seems more like it's useful as a permanent thermal paste
[00:11:48] <PetefromTn_> I like soldering even tho I SUCK at it
[00:11:49] <_methods> i get the same buzz from both lol

[00:12:24] <_methods> i suck at welding and soldering but i still love doing it
[00:12:29] <CaptHindsight> fine beach sand and lard will replace toothpaste in the future
[00:12:47] <malcom2073> yummy
[00:13:18] <CaptHindsight> where is my stupid article on motherboard?
[00:13:37] <CaptHindsight> oh yeah, I have to patent it first
[00:13:46] <PetefromTn_> jeez beach sand in toothpaste that sounds HORRIBLE
[00:13:55] <_methods> vice is so bad with the clickbait
[00:14:03] <CaptHindsight> and toothpaste is pleasant?
[00:14:42] <andypugh> Why is Aliexpress convinced I want to buy sexy female underwear? What has gone wrong with their algorithms?
[00:14:43] <PetefromTn_> a helluva lot more pleasant than beach sand have you ever biffed it on the beach or surfing and got a mouthful?
[00:15:06] <PetefromTn_> hehehe tell the truth andy you were looking at underwear models online
[00:15:08] <jdh> is biffed like snogged?
[00:15:10] <CaptHindsight> who cares it's the fcking future
[00:15:10] <malcom2073> andypugh: That self-balancing spoon thing is really cool
[00:15:18] <CaptHindsight> deal with it
[00:15:32] <andypugh> PetefromTn_: Only in incognito windows
[00:15:41] <PetefromTn_> incognito?
[00:15:47] <PetefromTn_> wth is that?
[00:15:56] <malcom2073> PetefromTn_: You don't know the joy of incognito windows?
[00:16:04] <malcom2073> You'll never type "you" and be worried that porn will come up before tube again!
[00:16:11] <PetefromTn_> apparently not but that is not really surprising
[00:16:53] <PetefromTn_> is it some windows explorer add on or something?
[00:17:18] <malcom2073> no
[00:17:23] <malcom2073> it comes withChrome, firefox, and IE
[00:17:32] <malcom2073> It basically doesn't record history or store cookies
[00:17:38] <PetefromTn_> well I have Chrome and FF but never found that LOL
[00:17:54] <malcom2073> from chrome, control shift N
[00:18:03] <PetefromTn_> aah
[00:18:22] <malcom2073> I use it if I'm using my email or facebook from a friends PC, so I don't accidently record my password or cookies there
[00:18:28] <PetefromTn_> so you mean I could have been viewing all of my Por....er questionable websites without fear all this time LOL
[00:18:29] <andypugh> This is a pretty cool machine: https://www.youtube.com/watch?v=mEsuTX6Empc
[00:19:20] <PetefromTn_> jeez look at that bigass flycutter!!
[00:19:30] <malcom2073> Hah wow, that's a huge cutter
[00:19:46] <andypugh> The 5th axis is very simple and pretty clever
[00:20:54] <PetefromTn_> if it's so simple and clever you should make one for my Cincinatti :D

[00:22:33] <andypugh> I might make one for my Harrison. It already has a manual adjustment there.
[00:23:00] <PetefromTn_> does it have a direct drive motor?
[00:23:15] <andypugh> Coaxial shaft
[00:26:42] <PetefromTn_> amazing how similar that is to your typical machining center really
[00:28:13] <andypugh> Yes, it isn’t anything special, just exactly the right fixtures for that specific job.
[00:29:15] -!- ibaca has quit [Ping timeout: 260 seconds]
[00:30:18] <PetefromTn_> they actually show them making the millhead in the video
[00:33:06] <andypugh> They don’t show what the bearing is, though.
[00:33:22] <malcom2073> How does that work, for like rotary tables?
[00:33:27] <malcom2073> Can't be dovetail
[00:34:35] <Sync> the bearing probably is some two angular rollers
[00:34:39] <andypugh> It could be a dovetail. It would be perverse and difficult, but I have thought of two ways to do it.
[00:34:47] <Sync> or a rotary style X roller bearing
[00:35:21] <andypugh> X roller is right for a retrofit on a machine like mine.
[00:35:38] <malcom2073> Ohhh hmmm
[00:35:46] <andypugh> I suspect they have a pair of AC bearings
[00:36:30] <PetefromTn_> never seen an X roller before
[00:36:45] <andypugh> Or maybe a big needle roller and two thrust bearing
[00:36:56] <andypugh> X-rollers are cool. And very expensive
[00:37:24] <Sync> I got a few for cheaps
[00:37:34] <andypugh> http://timkenbearing.cn/productshow174.html
[00:37:35] <PetefromTn_> maybe just a big ol bolt and a brass bearing :D
[00:37:39] <Sync> they oxidize around somehwere
[00:38:19] <Sync> yeah the neat thing is that you don't need anything with them
[00:38:31] <malcom2073> I got a harmonic drive with some cross rollerbearings in it
[00:38:36] <PetefromTn_> maybe just a big machined boss and some crisco?
[00:38:53] <PetefromTn_> ooh and an e-ring
[00:38:58] <PetefromTn_> ;)
[00:43:10] <andypugh> You can get bearings with built-in drive gears and encoders.
[00:44:08] <malcom2073> andypugh: We're making some compact brushless motors as part of some robotic arm assemblies, they're amazingly compact and put together. The motor is part of the housing, the harmonic drives serves as one of the bearing surfaces, etc
[00:44:18] <malcom2073> They're super compact
[00:44:38] <andypugh> If you have any rejects that nees a home…
[00:45:14] <malcom2073> Hah I wish
[00:45:17] <Sync> the same way as kuka does it
[00:45:20] <malcom2073> They're something like 20-30grand each just in pieces
[00:45:28] <malcom2073> lemme find a picture
[00:47:10] <andypugh> I made my own motor a few years ago to wrap round a large shaft and operate coaxially with it: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5685034302549414130
[00:47:22] <malcom2073> Oh nice
[00:47:26] <malcom2073> I can't find any pictures of the motor heh
[00:47:35] <malcom2073> http://imagecache.jpl.nasa.gov/images/640x350/robosimian-640-640x350.jpg
[00:47:38] <malcom2073> It's the arm motors for that
[00:48:12] <andypugh> Yes, OK, I can see we have different budgets
[00:48:26] <malcom2073> Hah, I wish I had budget to do this sorta stuff myself
[00:48:56] <malcom2073> I love the integrated motor and frame thing though
[00:49:09] <malcom2073> Want to do something similar myself, but can't find a good use for it yet heh
[00:49:12] <andypugh> Sometimes having a budget stops you finding the really special solution.
[00:49:29] <Sync> yeah exactly the same way kuka does it
[00:50:10] <andypugh> Well, my motor was for: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5998926150725388018
[00:50:28] <Sync> oh neat
[00:50:29] <malcom2073> Oh slick
[00:50:30] <Sync> did it work?
[00:50:35] -!- ibaca has quit [Ping timeout: 264 seconds]
[00:50:45] <andypugh> It _nearly_ worked.
[00:50:54] <Sync> dem torques?
[00:51:05] <andypugh> There is a problem with one of the internal encoders.
[00:51:10] <Sync> ah
[00:51:26] <malcom2073> doh
[00:51:32] <andypugh> I proved it _could_ work, but mine isn’t actually useful.
[00:52:33] <andypugh> If I needed it badly enough I could probably just use the hall sensors. There is enough gearing in the boring head that that is probably enough
[00:53:10] <Sync> or you use no encoder at all
[00:53:15] <Sync> and use hfi sensing
[00:53:44] <andypugh> It’s annoying, I paid a fair bit of money for the encoders to be laser cut: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5746547530954320162
[00:53:57] <Sync> ew
[00:54:43] <andypugh> When I say “a fair bit” I mean £50
[00:55:18] <Sync> ah well
[00:55:21] <Sync> that's not too bad then
[00:56:17] <andypugh> If I ever need to bore a spherical pocket in something (like the spindle plate of a hexapod) I will resurect it.
[00:56:43] <Sync> http://www.heise.de/imgs/18/2/1/4/8/8/3/973b1cf8c6980cb5.jpg
[00:57:13] <andypugh> Interesting styling.
[00:57:58] <andypugh> They appear to have tried excessively hard to keep the kinematics simple.
[00:58:21] <Sync> well
[00:58:27] <Sync> it is the cheapest way to do it
[00:58:47] <Sync> just a few servos + harmonic drives
[00:59:07] -!- ibaca has quit [Ping timeout: 260 seconds]
[00:59:32] <andypugh> ie, all the joints are in a single plane, which saves the controller doing some calcs that it would be doing anyway, at the expense of more complex castings.
[00:59:49] <Jymmm> In response to Sync's pic... https://www.youtube.com/watch?feature=player_detailpage&v=2ImZTwYwCug#t=30
[01:00:19] <andypugh> I am pretty sure the controller is doing the DH calcs, and multiplying by a zero offset in some terms
[01:03:20] <Sync> I don't think so
[01:03:54] <Sync> the prototype controller for them in the lab runs on a lot of fpgas
[01:04:24] <andypugh> Jymmm: I have mixed feelings about that video. I can’t deny that the chap is an expert exponent of his genre. But the dancers seem to be rather less callipigian than they should be.
[01:05:18] <Jymmm> andypugh: I agree, they do seem to be lacking considering the content
[01:05:42] <Sync> unfortunately my wohlhaupters do not have the removable shaft
[01:06:36] <Jymmm> andypugh: Far more appropriate http://media.tumblr.com/tumblr_kudrjfpehg1qaokzy.jpg
[01:06:49] <andypugh> Sync: I reckon if you were brave you could make the modification
[01:07:06] <Sync> well I can just turn my sk40 one down, as it will not fit my spindle
[01:08:10] <Sync> but I'm not so keen on winding my own motor :D
[01:08:29] <Jymmm> NSFW but mercy... http://40.media.tumblr.com/tumblr_lyclagZ6yd1r56hifo1_1280.jpg

[01:13:01] <Jymmm> andypugh: I always thought that was a beer holder?
[01:13:40] <andypugh> Sync: I think that the register is 37mm, but don’t machine anything until I have measured.
[01:14:11] <andypugh> The threaded hole in the body might be the hard part, I think they are through-hardened.
[01:14:26] <andypugh> The differential screw is super-clever
[01:15:36] <Sync> hmm centroid seems to run linux on their frontends
[01:16:04] <Sync> oh they run a differential screw?
[01:17:15] <andypugh> I tend to use my boring head even when I don’t have to. This was machining a lathe toolpost. I wanted to generate a flat surface: https://picasaweb.google.com/108164504656404380542/Holbrook#6237961413474714578

[01:18:12] <Sync> oh, interesting
[01:19:10] <andypugh> There is a fine thread into the body and a coarse thread into the shank. You screw the shank on until the pegs are close then _loosen_ the allen screw into the shank, which pulls it onto the pegs and the head.
[01:19:29] <andypugh> it’s super-clever.
[01:20:16] <andypugh> it gives you the equivalent of a hex-socket screw down a hole that you could’
[01:20:29] <andypugh> n’t fit one down.
[01:21:43] <andypugh> I used exactlky the same idea to hold the extension on the ball screw of my mill : https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5639360949629091906

[01:22:15] <andypugh> In that case pulling up a taper down a 5mm hole in the end of the shaft.
[01:22:24] <Sync> yeah the idea is pretty clever
[01:22:46] <andypugh> Definitely something to have in your box of tricks
[01:22:48] <Sync> well, I'm not going to machine something really quickly, but there are encoders that would fit into that thing
[01:27:08] <andypugh> Sync: I have never actually described the clever idea in that boring head drive that made me get out of bed to find a pen and paper. But the way the encoders are arranged is part of it.
[01:27:58] <Sync> well. I'd chuck a DS90 in there and be done ;)
[01:28:06] <Sync> or a DS70 if 30mm ID is enough
[01:28:21] <Sync> and enjoyed 19 bits of resolution
[01:28:26] <andypugh> 50mm ID…
[01:28:36] <andypugh> And minimal length
[01:29:21] <Sync> the ds90 comes with 50mm id
[01:30:05] <Sync> and they are 10mm thick
[01:30:15] <PetefromTn_> Okay folks just one more hour until I am royalty! ;)
[01:30:18] <andypugh> If I was doing it again I might try to wind my own resolvers
[01:34:12] -!- spooq|2 has quit [Ping timeout: 255 seconds]
[01:35:23] <Sync> why?
[01:35:26] <Sync> there is no reason to

[01:35:47] -!- spooq [spooq!~spooq@185.16.160.73] has joined #linuxcnc
[01:36:13] <andypugh> The rest of the milling machine uses them, and I have 2 spare channels.
[01:36:33] <Sync> well, sure but I'd rather not wind my own
[01:36:42] <Sync> if there is a fitting encoder solution to be bought
[01:37:11] <andypugh> Everything I do is because I want to see if I can. None of my projects have any actual purpose.
[01:39:31] <Jymmm> andypugh, the little engine that could!
[01:39:56] <Sync> sure, but at some point it has to be over
[01:40:07] <Sync> and winding my resolvers is certainly not something I want to do
[01:40:30] <Jymmm> Sync: make a bobbin winding machine =)
[01:43:06] <andypugh> I wonder how much paint it takes to paint a lathe and the stand?
[01:43:28] <andypugh> Do I buy 1 litre or 5?
[01:44:37] <malcom2073> If you buy one, you'll need two. If you buy five, you'll probably need 34
[01:44:38] <malcom2073> 3/4
[01:45:08] <andypugh> I just have no feeling for paint coverage
[01:45:24] <Sync> moar coats
[01:45:36] <Jymmm> and do you need primer?
[01:45:58] <PetefromTn_> I used two pints
[01:46:24] <andypugh> OK, so that’s about a litre. including the stand?
[01:46:49] <PetefromTn_> no only the machine and the enclosure but honestly I have LOTS leftover
[01:47:16] <PetefromTn_> and I am rolling it on with a foam detail roller
[01:47:25] <andypugh> https://picasaweb.google.com/108164504656404380542/Holbrook#6154759374244307010 more or less area than this?
[01:47:28] <PetefromTn_> and a brush where the roller won't reach
[01:47:43] <malcom2073> The fork truck or the lathe?
[01:47:50] <PetefromTn_> heh
[01:47:54] <PetefromTn_> probably about the same
[01:47:59] <andypugh> The lathe. I like the colour of the telehandler
[01:48:10] <malcom2073> It is a pretty green
[01:48:41] <andypugh> OK, I will get a litre and maybe buy a second litre
[01:48:58] <andypugh> Or maybe I will buy 5 and paint everythign I own
[01:49:06] <PetefromTn_> actually I should clarify
[01:49:12] <PetefromTn_> one pint was for the primer
[01:49:16] <PetefromTn_> one was for the paint
[01:49:32] <PetefromTn_> I have quite a bit of primer leftover

[01:55:24] <andypugh> All-in, it is £20.33 for one litre (2.11227642 US pints) or £44.33 for 5 litres. (or £32.32 for 2 x 1 litre cans)
[01:55:54] <andypugh> malcom2073: The one I put a picture of up earlier? Yes. Twice
[01:56:03] <malcom2073> Nice, I've always wanted to give that a try
[01:56:09] <malcom2073> Be kinda cool to make a motor from scratch
[01:56:18] <malcom2073> That, and spinning things facinate
[01:56:19] <malcom2073> me
[01:56:26] <andypugh> It’s not nearly as hard or tedious as you might anticipate.
[01:57:21] <andypugh> Sync: Yes, motorcycle alternators are close.
[01:57:49] <andypugh> I am sure I have seen sites selling unwound outrunner stators.
[01:58:38] <andypugh> Most interesting stuff is a small number of turns of big wire, I think mine was 20 turns. It takes about an hour to wind a motor by hand.
[01:59:27] <malcom2073> Bigger wire allow for more current more torque?
[02:00:21] <malcom2073> More torque is more interesting heh

[06:27:48] <trentster> Hi all, what does it mean if during a program run LinuxCNC just stops at a certain point (shown as a blue line on plot) and will not continue?
[06:29:14] -!- [cube] has quit [Ping timeout: 246 seconds]
[06:29:36] <XXCoder> odd
[06:30:04] <XXCoder> havent used linuxcnc, not really but machines that just stop tend to mean there was m0 or it had a error somewhere
[06:30:24] <trentster> This is the line it stops on https://gist.github.com/trentster/a09329782c51eabdd26a#file-cut-1-ngc-L34
[06:31:25] <XXCoder> well. looks legit gc
[06:32:08] <trentster> yup its very odd - its generated by fusion 360 - it stops in the exact same place every time
[06:32:21] <XXCoder> f2.09 is quite specific
[06:32:49] <XXCoder> I find it odd that it is moving at Z and Y at once
[06:32:52] <XXCoder> line before
[06:33:17] <XXCoder> unless its making a 3d surface
[06:33:23] <XXCoder> anyway it seems okay
[06:33:29] -!- [cube] [[cube]!~cube@204.237.2.118] has joined #linuxcnc
[06:33:45] <trentster> its ramping down into a slot to 2mm depth
[06:33:55] <XXCoder> it is first floating number feed rate
[06:33:59] <trentster> it stops exactly at the point where its at 2mm depth
[06:34:27] <trentster> instead of carrying on the first pass all the way around at -2mm
[06:34:29] <XXCoder> and 2.09 is VASTLY slower than previous feed rates of 400+
[06:35:00] <XXCoder> it may not be stopped, just very dead slow.
[06:35:18] <trentster> yeah its very very odd. I will try regenerate and see if I can fix it.
[06:35:27] <XXCoder> whats feed units anyway
[06:35:28] <XXCoder> ipm?
[06:35:30] <trentster> I think you are right it looks like its stopped but just very slow
[06:35:48] <trentster> no I am metric its feeding at 446mm per minute
[06:36:09] <XXCoder> mmpm it is then heh
[06:36:17] <trentster> its an acrylic test cut with single flue o bit
[06:36:28] <XXCoder> 2.09 mm per min seems extremely slow yeah
[06:36:41] <trentster> yeah must be a bug in fusion 360
[06:37:52] <XXCoder> hopefully, problem solved
[06:39:59] <trentster> XXCoder: thanks you are a genius, one of the toolpaths when I regenrated after changing a tool got a feedrate of 2.9
[06:40:04] <trentster> all sorted now :-)
[06:40:13] <XXCoder> np, and nope not a genius
[06:40:20] <XXCoder> just did basic programming analysis
[06:40:57] <XXCoder> though isnt 2.9 barely faster than 2.09?
[06:41:18] <trentster> I meant 2.09 ;-)
[06:41:29] <trentster> its not fixed and back to 446mmpm
[06:41:45] <XXCoder> so it is 446 now
[06:42:19] <trentster> which seems way to slow for cutting acrylic
[06:42:20] <trentster> https://monosnap.com/file/X6N7TGF9yVFCZ1UyqPyngSDt3n3zvq
[06:42:53] <trentster> but its the speeds and feeds GWizard recommends which seems kinda slow - I am pretty sure its gonna gum up the bit and melt
[06:43:04] <XXCoder> in least its not "seems stopped slow"
[06:44:51] <trentster> let me go run it quick and see what happens - I predict heat and bit weld

[09:14:14] <trentster> if you make less than $100K a year from your business its still free

[09:15:30] <XXCoder> indeed.
[09:15:37] <XXCoder> now that is decemt
[09:15:51] <trentster> I wonder how much solidworks 2016 costs
[09:15:52] <XXCoder> gonna find my impossible to find windows 7
[09:16:15] <XXCoder> quotes I hate priceless websites
[09:18:09] <XXCoder> The basic commercial license of SolidWorks has not changed in price since it was first released in 1996. One license is $3995. Annual Subscription service, which covers technical support and upgrades for one year, is $1295.
[09:18:55] <XXCoder> if I got to 100k a year, 3995 is real cheap.
[09:19:04] <XXCoder> decent.
[09:21:58] <trentster> XXCoder: in Au fusion 360 paid version for business use is $260 USD per year - so lets call that $22 a month
[09:22:29] <toastydeath> tbh if you're going to spend 4k
[09:22:37] <toastydeath> you should look at Catia or PTC Creo
[09:22:40] <trentster> So thats 15 Years of usage for the same price as 1X solidworks licence
[09:23:22] <toastydeath> solidworks is good but not great, imo

[09:24:55] <trentster> toastydeath: I will take your word for it, I have not had exposure to much. I can say what I like about fusion is integrated CAD / CAm and the fact its multiplatform
[09:25:26] <toastydeath> just for comparison, PTC Creo has had CAD/CAM since before solidworks was a product
[09:25:34] <toastydeath> back when it was pro/e
[09:26:14] <toastydeath> it is much, much more mature and wildly more powerful - once you get the hang of using parametric tools, the jump over isn't insane. solidworks cornered the market by being easy to learn, but not by being particularly powerful
[09:26:43] <toastydeath> sort of like Word vs. InDesign
[09:26:46] <toastydeath> (or Quark)
[09:27:33] <trentster> interesting - but isnt fusion also parametric?
[09:28:01] <toastydeath> yep, they're all parametric
[09:28:09] <trentster> I think its like most things tho, once a person has learnt and semi mastered a CAM package they tend to stick with it
[09:28:13] <trentster> its a big learning curve
[09:28:13] <toastydeath> but solidworks is better for someone who has never used parametric tools

[09:31:42] <toastydeath> no idea
[09:32:43] <toastydeath> never heard of freecell - do you mean freecad, or is this another package?
[09:33:01] <witnit> is mach even comparable to emc?
[09:33:49] <XXCoder> duhh
[09:33:52] <XXCoder> freecad yes
[09:33:55] <trentster> this is freecell https://monosnap.com/file/C8se3xvW5ke2LSjWfCpC929zbnjATs
[09:33:59] <toastydeath> freecad is parametric
[09:34:00] <XXCoder> I used to play with freecell so much.
[09:34:03] <trentster> pretty sure its not parametric :P
[09:34:30] <XXCoder> trentster: windows 7 version is my most favorite.
[09:34:37] <XXCoder> xp is decent, and windows 10 has ads
[09:34:41] <witnit> I mean linuxcnc is not like mach since mach is based around cnc, where linuxcnc is really and truly open set of tools for creating an enhanced machine controller
[09:35:24] <XXCoder> time to use my brand new 32 gb usb drive lol
[09:35:26] <trentster> witnit: I guess the plug and play nature of Mach is appealing to folks
[09:35:37] <XXCoder> gonna dd the win7 cd to file
[09:35:41] <trentster> LinuxCNC is more get under the hood kind of thing

[09:42:42] <XXCoder> okay
[09:42:55] <XXCoder> my linuxcnc pc is dd'ing windows 7 image to filke
[09:43:27] <XXCoder> took me a bit to figure command work as well as how to find full device path.
[09:43:39] <witnit> man dd
[09:43:40] <witnit> :)
[09:43:50] <XXCoder> yeah that was easy part
[09:44:03] <XXCoder> other took me couple minutes to remember just use mount | grep cdrom

[09:44:15] <XXCoder> man XXCoder
[09:44:17] <witnit> i never use man anymore it seems, i end up just googling until it comes into play

[09:46:59] <XXCoder> man is still useful, though it seem to be starting to be nelicted
[09:47:07] <XXCoder> too bad really.
[09:47:14] <XXCoder> command itself tend to support --help too
[09:50:52] <trentster> linux man pages are not very good - unlike FreeBSD or Solaris which are maintained and comprehensive
[09:51:21] <XXCoder> thats one of flaw with linux
[09:51:29] <XXCoder> people work on stuff theyre interested on
[09:51:39] <XXCoder> which means more boring stuff tend to go sale

[11:43:51] <zhivko> which binary then ?
[11:44:10] <zhivko> just to jog motors or run whole gcode file

[15:40:50] <archivist> methinks the odds are a constant
[15:40:56] <PetefromTn_> actually I got the powerball number on one of the tickets
[15:41:10] <PetefromTn_> so I get a couple bucks so I don't have to pay anything this time
[15:41:15] <PetefromTn_> and yeah the odds never change
[15:41:27] <malcom2073> oh, hwh
[15:41:28] <archivist> the amount in the pot varies
[15:41:34] <PetefromTn_> the only thing that changes is the number of people trying
[15:41:41] <PetefromTn_> which makes the odds someone will win better
[15:42:07] <PetefromTn_> the odds are something like 1 in 292 something million
[15:42:19] <archivist> more money in the pot, more fools trying
[15:42:41] <PetefromTn_> yeah now it's SUPER INSANO VILLIAN money ;)
[15:42:46] <archivist> we had a record roll over pot this weekend
[15:43:06] <archivist> I didnt join in
[15:43:10] <PetefromTn_> apparenlty it is up to 1.3 billion or something crazy like that
[15:43:18] <malcom2073> crazy
[15:43:59] <archivist> they hit a max here then spread at the next level if not won
[15:44:40] <PetefromTn_> that is by far the highest powerball jackpot in history If I am not mistaken
[15:45:03] <PetefromTn_> I'd be happy with the interest on that money ;)
[15:45:40] <JT-Shop> I'm happy now
[15:47:31] <PetefromTn_> yup I'm pretty happy myself LOL

[16:26:55] <bobo_> JT-Shop Have my own O-scope ,thanks though. was wondering what you used to help track down the noise problem
[16:27:01] <jthornton> I have the pwr led on the 7i92 lit up now but mesaflash --device 7i92 returns no 7i92 found
[16:27:31] <jthornton> the AB servo wiring best practices pdf
[16:30:02] <bobo_> what/where is this -AB servo wiring best practices pdf -?
[16:35:57] <pcw_home> For real time access to the 7I92 I would connect it to the motherboard port
[16:35:59] <pcw_home> and jumper the 7I92 for 10.10.10.10 (W5 down W6 up) These setup the motherboard
[16:36:00] <pcw_home> Ethernet port for static IP of 10.10.10.1, netmask 255.255.255.0

[16:37:43] <pcw_home> if you use the default 192.168.1.121 address this likely overlaps your internet routers NAT range
[16:39:15] <pcw_home> (which is fine if you are not doing realtime and the 7I92 is on the MAC that connects to the router )

[16:41:25] <pcw_home> if you use a wall wart make sure you ground the 5V common locally (Ive see the switching ones with about 70V of floating HF and 60Hz noise)

[17:07:28] <CaptHindsight> small boards made by small hands that have small stomachs
[17:08:36] <CaptHindsight> manufacturing is actually automated and the parts vendors are happy with smaller margins than US suppliers
[17:09:12] <CaptHindsight> thats why TI and Motorola could no longer compete in areas like cellphones
[17:09:43] <JT-Shop> Tom_itx: what do they do?
[17:10:05] <CaptHindsight> out capitalized by better capitalists
[17:10:32] <FloppyDisk> motivated capitalists...
[17:10:57] <CaptHindsight> better at capitalism, not morally superior
[17:11:19] <Sync> which is interesting, because motorola brought SiGe BiCMOS to the market
[17:11:41] <Sync> developed by my institute :3
[17:11:56] <CaptHindsight> Motorola had poor management like AMD and HP
[17:12:28] <CaptHindsight> could have been replaced by magic 8 balls and hardly done worse
[17:13:30] <Sync> well, AMD got rekt by global foundries

[17:27:13] <Tom_itx> did you get a price on catia?
[17:27:14] <zeeshan> way overpriced for what they do
[17:27:15] <zeeshan> yea dude
[17:27:20] <Tom_itx> how much?
[17:27:21] <zeeshan> 18,000 for the base software
[17:27:29] <zeeshan> with no modules
[17:27:40] <Tom_itx> my bud paid 75 way back when
[17:27:41] <zeeshan> inventor is the cheapest
[17:29:02] <Sync> zeeshan: nx is best
[17:29:14] <zeeshan> i don't like it
[17:29:18] <zeeshan> but it has everything included for the price
[17:29:24] <zeeshan> as far as i can tell
[17:29:45] <Sync> I had to work with almost all packages in uni, and they all suck
[17:29:50] <Tom_itx> zeeshan, take more classes :D
[17:29:52] <Sync> now for yoloing about nx does fine
[17:29:58] <zeeshan> Tom_itx: i was formally trained in nx
[17:29:59] <zeeshan> i hate it
[17:30:12] <zeeshan> ive been formally trained in solidworks, autocad 2d, inventor
[17:30:16] <Tom_itx> to get the student price..
[17:30:16] <zeeshan> catia i only messed around on my own
[17:30:21] <zeeshan> o
[17:30:37] <PetefromTn_> Can't afford NONE of that shite :(
[17:31:06] <zeeshan> the stats show that inventor and solidworks keep growing every year
[17:31:24] <zeeshan> i think in a few years, inventor might be the market holder instead of solidworks

[17:33:14] <renesis> its like photoshop, itll never go away
[17:33:19] <renesis> too widely pirated
[17:33:28] <zeeshan> you can get it for 800 bux
[17:33:30] <zeeshan> no need to pirate
[17:33:39] <renesis> okay well tell that to the whole world
[17:33:53] <renesis> 800 is a lot when your business isnt cad
[17:35:12] <Sync> if you cannot afford 800 for your business, you are probably doing it wrong to some degree
[17:35:46] <renesis> also my guess is they didnt mind the pirates, as it helps keep them dominant in the market and increases the number of people trained to used the software
[17:36:05] <renesis> sync: sure but people who make money dont do it by throwing money away
[17:36:17] <zeeshan> i wonder if the subscription pack is ncessary for solidworks
[17:36:34] <zeeshan> its 8000~ without it. includes everything motion simulation wiring, etc
[17:36:35] <Sync> well, that's true but you need to invest in your business to grow it so eh

[17:59:34] <ReadError> its very hard stuff it seems
[17:59:37] <zeeshan> it is
[17:59:40] <zeeshan> no elongation
[18:01:22] <zeeshan> i like aluminum in static situations
[18:01:37] <zeeshan> but man if you put that stuff in cylic situations like a flywheel or driveshafts
[18:01:53] <zeeshan> their fatigue strength is so weaksauce
[18:02:25] <zeeshan> i think 7075 is 70ksi yield and fatigue strength is 23ksi, which is decent cause regular steel is around 29ksi
[18:02:39] <zeeshan> but 6061 is 40ksi yield and 12-14ksi fatigue

[18:03:19] <Sync> aww
[18:03:27] <Sync> need to do some for some aluminium crossmembers
[18:03:44] <zeeshan> sync if i were to approach a fatigue problem
[18:03:49] <zeeshan> i'd start with a static fea
[18:04:09] <Sync> I'm no stranger to general fea
[18:04:10] <zeeshan> find the stress concentrations and just keep them below the fatigue limit
[18:04:14] <Sync> well
[18:04:23] <Sync> yeah
[18:04:46] <Sync> but most packages will do dynamic fatigue
[18:04:46] <zeeshan> but that i think is a very conservative approach

[18:05:29] <zeeshan> im just thinking
[18:05:33] <zeeshan> what the difference is vs static fea
[18:05:42] <zeeshan> your input load would be some sort of sinusoidal
[18:05:47] <zeeshan> or time variant
[18:06:07] <Sync> I'm trying to be lighter AND stronger than the stamped sheetmetal part that is currently on the car
[18:06:14] <Sync> both of which on its own is easy
[18:06:20] <zeeshan> and then your failure criteria now is some sort of soderberg, gerber goodman
[18:06:36] <zeeshan> so you have number of cycles as an input
[18:06:51] <zeeshan> and need to input cycles vs strength info into the software
[18:07:09] <Sync> well, they usually give you a safety factor vs time graph
[18:07:23] <Sync> due to the integrated fatigue

[18:41:12] <Jymmm> CaptHindsight: 1) I need new lenses (or polish the ones I have) $40. 2) high perfomaance street legal bulbs $$$, 3) mount that lightbar behind the grill and wire to the high beams.
[18:41:17] <CaptHindsight> I'm considering a tracking system and laser to start taking them out while driving
[18:41:58] <Jymmm> CaptHindsight: Ah, a mini phalanx is what you want. Great for clearing traffic too
[18:42:28] <CaptHindsight> just the LED's not the entire vehicle
[18:42:36] <Jymmm> CaptHindsight: https://www.youtube.com/watch?v=-L0ZAGOuaqg
[18:43:11] <CaptHindsight> a rear window spotlight is also handy when they decide to tailgate you
[18:43:35] <CaptHindsight> I'm surprised that there aren't more incidents over this
[18:43:42] <Jymmm> That I could wire to the roof rack =)
[18:46:55] <Jymmm> CaptHindsight: What were you going to make?
[18:47:40] <CaptHindsight> was just thinking about semi-custom LED retrofits for older and classic cars
[18:48:19] <Jymmm> older? Like with glass bulbs, or plugin bulbs?
[18:48:52] <CaptHindsight> complete assemblies for new car effects blended into old styles
[18:49:40] <Jymmm> I was asking HOW old?
[18:49:53] <CaptHindsight> like the Escalade look http://static2.consumerreportscdn.org/content/dam/cro/news_articles/cars/2015-Cadillac-Escalade-headlight-corner-ATC.png for pre 80's
[18:50:03] <Jymmm> ah
[18:50:47] <CaptHindsight> or 90's rear wheel drive Japanese
[18:51:38] <CaptHindsight> isn't California making it more difficult to drive a pre-ECU car on the road?
[18:52:43] <Jymmm> Not that I'm aware of. iirc the rule is 32 years and no smog requirement, except at title transfer
[18:52:44] <CaptHindsight> or maybe it just effects Calif emissions vehicles from the late 60's and up

[20:37:54] <Topy44> anyone here got a cnc lathe or experience working on one? i need some advice on designing a part that needs to be semi-mass-produced (as in, 30 or so)
[20:38:06] <Topy44> like, how to design it so its easy to make
[20:38:24] <CaptHindsight> easy for whom?
[20:38:38] <Topy44> easy for whomever is going to make the parts :)
[20:39:02] <CaptHindsight> design for manufacture comes from experience
[20:39:14] <Topy44> yeah thats the point
[20:39:20] <CaptHindsight> about all you can do is post something similar and as for comments
[20:39:29] <CaptHindsight> as/ask
[20:39:38] <Topy44> my entire experience with lathe machining is some very simple work on a manual lathe
[20:39:58] <Topy44> well i already designed a part, let me just make some pictures to show
[20:40:12] <CaptHindsight> no need to apologize, post drawing/ models or pics
[20:42:55] <Topy44> some renderings first: http://dump.t44.org/laser%20assembly%201.JPG http://dump.t44.org/laser%20assembly%202.JPG http://dump.t44.org/laser%20assembly%203.JPG
[20:43:28] <Topy44> total outer dimension of the widest part is 30mm
[20:43:45] <Topy44> the threads are M14x0.5 and M9x0.5
[20:43:58] <Topy44> the parts to be made are the 4 silver ones
[20:45:13] <Topy44> i did design it so that i believe it should be possible to make the parts without rechucking (is that the right word? i mean: removing the part from the chuck and turning it around)
[20:46:16] <Topy44> umh, forgot the M10x0.5 thread
[20:46:48] <Topy44> material is aluminium
[20:47:07] -!- Duc has quit [Quit: Leaving]
[20:47:11] <Topy44> i can make a technical drawing with measurements and stuff if needed, but i think you get the idea
[20:47:59] <jdh> no help, but what holds the diode holder part in?
[20:48:12] <Topy44> a set screw (not pictured)
[20:48:36] <Topy44> (and yes i am aware that similar parts are available cheap from china, but we bought several and the tolerances are so bad that they are useless for our purpose)
[20:49:50] <jdh> the lens holder or wtf has to be machined from two sides?
[20:50:03] <Topy44> why?
[20:50:50] <jdh> it was a question!
[20:50:54] <Topy44> ah
[20:51:01] <Topy44> no, i believe everything can be machined from one side
[20:52:37] <Topy44> some parts need to be cut left to right, but other than that it should be fine i believe
[20:53:22] <_methods> that part where the diode is held won't work
[20:53:27] <Topy44> ok?
[20:53:31] <_methods> where it's holder gets into the threads
[20:53:38] <_methods> you'll have interference
[20:53:49] <_methods> you'll need to make that area a smaller diameter or something
[20:53:54] <Topy44> huh..explain please
[20:54:12] <_methods> in your section view
[20:54:14] <jdh> you figure that out after the first couple parts
[20:54:15] <Topy44> yes
[20:54:43] <_methods> not sure what that oring is accomplishing either with no compression on it
[20:54:45] -!- sumpfralle [sumpfralle!~lars@erina.opennet-initiative.de] has joined #linuxcnc
[20:55:03] <Topy44> the oring is there to take any play out of the focusing mechanism
[20:55:03] <jdh> dust/vibration?
[20:55:43] <Topy44> might want to use a smaller one
[20:55:54] <Topy44> but you get the idea. thread cutting into oring
[20:56:22] <jdh> it would probably hold withouth the threads, and woudln't destroy itself
[20:56:35] <Topy44> yes but adjustment would be hard
[20:56:36] <jdh> normal o-ring dims

[20:57:44] ChanServ changed topic of #linuxcnc to: LinuxCNC is a linux-based open-source CNC control. | Latest releases: 2.7.3 and 2.6.12 | http://www.linuxcnc.org
[20:58:13] <Topy44> there are two major problems this whole thing is supposed to fix
[20:58:14] <JT-Shop> a few more 021 size trees then it's time to get out the 291!
[20:58:29] <Topy44> that is: problems with the chinese made ones
[20:58:56] <Topy44> first: the lens is adjusted directly, meaning you need to interrupt the beam with a tool when adjusting focus, making it hard to focus
[20:59:24] <Topy44> second: the lens threads have _tons_ of play, it wiggles around like hell, making it almost impossible to align
[20:59:53] <Topy44> and third: the diode doesn't fit perfectly, it has about half a mm of play, meaning it will be mounted off-center
[21:00:37] <Topy44> the "base plate" of the diode has a very precise outer diameter, so that can be used to properly center it
[21:00:50] <Topy44> and the front of that plate is the reference for the focus point
[21:02:34] <Topy44> the lens has an M9x0.5mm outer thread, i want it to be permanently set into the lens holder with some loctite and then adjust that lens holder
[21:02:51] <Topy44> so that M14x0.5mm thread becomes the focus adjustment

[21:03:33] <Topy44> neat! got a lot of stuff from fleamarkets, but never a kiln
[21:04:13] <Topy44> anyway. any more comments/hints/suggestions for my design?
[21:04:54] <jdh> 3 set screws for unanticipated misalignments?
[21:06:24] <Topy44> of the diode holder?
[21:06:42] <jdh> yeah, or any of the parts
[21:07:08] <Topy44> the two parts should be made to relatively close tolerances, and also _very_ small misalignments of the diode don't actually matter much
[21:07:15] <Topy44> as in, .1mm or so
[21:07:31] <Topy44> but yeah, 3 set screws instead of one might be a good idea
[21:08:12] <jdh> what can it cut?
[21:08:23] <Topy44> ?
[21:08:36] <jdh> the diode. or just engraving?
[21:08:47] <Topy44> neither actually
[21:09:02] <Topy44> well, its a 2W 445nm laser so it _could_ cut/engrave but thats not what we use it for :)
[21:09:09] <Topy44> and hm... yeah... set screws around the lens holder to fix it once focus is correct are a good idea
[21:10:58] <Topy44> not sure about that o-ring solution but not sure how else to do it

[21:13:50] <jdh> o-ring is probably fine, but I would not have it engage threads
[21:14:17] <Topy44> why not? so have it in the front part instead?
[21:14:38] <Topy44> note that focus should be adjusted once and never touched again, so wear is not an issue
[21:14:41] <jdh> yeah, notch that part

[22:29:41] <JT-Shop> testing them for your use of course
[22:31:17] <the> JT-Shop, so i just put the .ngc sub as on your website into my install and reference them in my ini? thats it? i dont need anything else?

[23:14:30] <FloppyDisk> JT-shop: Looks like micges commented on github on the sserial error... https://github.com/LinuxCNC/linuxcnc/issues/27#issuecomment-170373201
[23:14:47] <FloppyDisk> Awesomeness at work...
[23:15:00] <FloppyDisk> I hope - I don't know any better.
[23:24:04] <JT-Shop> the: I think it is there but hidden, better to just use mine and ones from the forum
[23:24:16] <JT-Shop> like I said just get one to work then add more
[23:31:00] <JT-Shop> FloppyDisk: are back to 2.6?
[23:35:16] <the> does anyone know what .ngc stands for? ie the ngc?
[23:35:37] <JT-Shop> the: you get started?
[23:35:39] <the> linux g-code?
[23:35:59] <JT-Shop> look at the history of LinuxCNC
[23:36:18] <Roguish> could be 'Nist G-Code'
[23:36:22] <the> JT-Shop, getting there, I found the ngcgui files and now I can edit my ini sensibly to include the path.. just doing it now.
[23:36:40] <JT-Shop> that makes sense
[23:36:45] <JT-Shop> the: good
[23:37:00] <the> if I run ngcgui from the terminal it works..
[23:37:18] <the> so i now need to edit my ini and try to include the subs as tabs..
[23:37:55] <the> I not actually stupid it just appears that way for now :-) lol..
[23:38:17] <the> nist g-code sounds plausible..
[23:38:21] <JT-Shop> everyone is a noob at one point
[23:38:34] <Roguish> the: one of the little keys in ngcgui is the font size to get every thing on the screen.
[23:38:52] <the> Roguish, ok..
[23:39:19] <the> JT-Shop, the learning curve is steepish. It was easier for overhaul the machine!
[23:39:26] <JT-Shop> the: I think you will find my subs a complete set for a lathe
[23:39:52] <the> JT-Shop, yes, I looked at them, they appear perfect... that is why I want to get it going..
[23:40:57] <JT-Shop> maybe not perfect but they work for me
[23:41:06] <the> JT-Shop, i already installed the scripts from andy pugh - will that stop ngcgui working?
[23:41:26] <JT-Shop> you would have to ask Andy that question
[23:41:43] <JT-Shop> might be past his bed time...
[23:42:17] <the> JT-Shop, I still do not really know about the py stuff and the glade - wondering if you can have the different widgets all in the same axis layout? lol..
[23:43:18] <JT-Shop> yea you can have a pyvcp and ngcgui on the same axis panel
[23:43:31] <JT-Shop> not sure about gladevcp and pyvcp but it might work
[23:44:02] <the> JT-Shop, well i will simply edit them out until i get ngcgui working then put them back and see...
[23:45:21] <JT-Shop> best plan is one step at a time
[23:45:34] <the> JT-Shop, yes..
[23:47:17] <Roguish> the: go slow and easy. baby steps. always be able to back up. WRITE LOTS OF NOTES.
[23:49:04] <the> I know computers and machines and engineering but I completely new with g-code and linuxcnc - very frustrating!
[23:50:46] <Roguish> oh, and also, rtfm. and if ya still need help, ask. no problem.
[23:51:26] <JT-Shop> not trying to create a thermonuclear overload but I have a couple of pyvcp buttons that save me a ton of time Touch off to material and touch off to fixture
[23:51:49] <JT-Shop> yea rtfm and if you find something wrong tell me!
[23:52:14] <Roguish> you are the man, JT !!!
[23:52:56] <the> JT-Shop, that sounds very interesting, at the moment I do it by hand every time, touch off pyvcp - please tell!
[23:53:07] <the> takes ages..
[23:53:29] <the> Roguish, the manual is very very dry! but I try, lol..
[23:54:16] <Roguish> I have the browser home page set to lcnc docs.....

[23:55:44] <the> Roguish, lol.. I just printed out the g-code quick reference - I suppose that was just wishful thinking..
[23:57:33] <Roguish> gcode is a simple language. there's a couple of oddities, but it's not difficult. even if you use a cam to write gcode, you should be able to read it.
[23:58:51] <JT-Shop> the: in my config files look for z-touchoff and z-material-touchoff
[23:59:34] <JT-Shop> postgui.hal net z-material halui.mdi-command-10 <+ pyvcp.z-material-touchoff
