[02:16:43] <JesusAlos> hi
[02:26:50] <Deejay> moin
[05:04:44] <XXCoder> hey Wolf_Mill
[06:20:28] <_methods> wow turkey shot down a russian jet
[06:21:58] <DaViruz> after ten warnings allegedly
[06:22:53] <_methods> crazy
[06:23:02] <DaViruz> i kind of wish sweden did it some time
[06:23:15] <DaViruz> but its probably not worth the aftermath
[06:23:26] <_methods> i thought they might sink the sub
[06:23:56] <DaViruz> tbey proba ly genuinely tried
[06:24:02] <_methods> oh they did
[06:24:18] <_methods> i think finland and sweden were actually working together on that one
[06:24:23] <DaViruz> we did damage one in the eighties
[06:24:41] <DaViruz> (not the ond that ran ashore)
[06:24:47] <_methods> this one was fairly recent
[06:25:07] <DaViruz> yeah i know
[06:26:00] <_methods> this should make putin even more insolent
[06:26:06] <DaViruz> our airforce is a joke nowadays sadly
[06:26:40] <DaViruz> weve went from the third largest int the world to probably the third smallest
[06:26:49] <_methods> yeah it looks like most of the weapons race for the sky is happening in usa and china now
[06:28:00] <_methods> oh wow it was actually turkish jets that shot them down
[06:28:11] <_methods> i figured it was just a SAM or something
[06:29:36] <DaViruz> from whai i've heard it was a ground launched attack
[06:29:45] <_methods> well after the flight mh17 incident the russians should keep their mouths shut
[06:29:56] <DaViruz> indeed
[06:30:00] <_methods> they just said on the news here it was 2 f-16's
[06:30:01] <DaViruz> but they wont
[06:30:08] <DaViruz> oh
[06:30:10] <_methods> turkish f-16's
[06:30:12] <_methods> but i'm not sure
[06:30:18] <_methods> you can never trust the news here
[06:42:52] <_methods> some news places are saying it was shot down by surface to air missile
[06:44:32] <_methods> oh ouch the syrian rebels captured one of the pilots too
[06:49:52] <Tom_itx> morning
[06:56:45] <_methods> allooo
[06:59:51] <Tom_itx> it's so close to thanksgiving i thought you mean a real turkey got the plane :)
[07:01:46] <Deejay> lol
[07:03:17] <_methods> gobble gobble
[07:03:32] <archivist> frozen chickens usually damage engines....actually how they test engines for bird strike
[07:04:04] <Tom_itx> yes
[07:04:08] <_methods> well russians frozen relations with these turkeys took down this jet
[07:04:14] <_methods> buwhahahhaha
[07:04:59] <_methods> terribad joke
[07:05:25] <Tom_itx> it's still earl.. i'll let it pass
[07:05:29] <Tom_itx> early
[07:06:16] <_methods> tnx
[07:06:21] <_methods> coffee still not kicked in
[08:23:24] <MattyMatt> archivist. the story I heard was that the americans instructed the british to fire live chickens, but they only had frozen. everything failed the frozen chicken test
[08:24:46] <MattyMatt> now they use dead but thawed
[08:25:54] <archivist> I got the story from Hucknell by an RR trust person (test bed site)
[08:26:16] <MattyMatt> so they still use frozen? that's extreme
[08:26:39] <MattyMatt> I guess an engine might injest a hailstone nearly that big
[08:27:25] <archivist> the test is destructive and to make sure nothing comes out the engine case to damage the plane
[08:28:04] <MattyMatt> I thought they had explosives for that test
[08:28:35] <MattyMatt> the chicken injestion is supposed to be without damage. it was originally for the plexiglass canopies in WW2
[08:28:44] <archivist> some tests are horizontal below ground so parts can only travel in concrete
[08:30:13] <MattyMatt> there was a good tour of the RR factory on BBC quite recently, but that was a carefully managed recruitment film
[08:30:44] <archivist> the RR trust has the historic collection
[08:31:08] <archivist> also has a place in Derby
[08:32:06] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=rolls+open+day+PD
[08:47:46] <MattyMatt> https://youtu.be/sQPpdmoZhj8?t=10m28s here's the current test stand
[08:48:23] <MattyMatt> there's some good stuff in that film, like how they inflate the fan blades, and how they cast the turbine blades as single crstals
[08:55:41] <MattyMatt> "a stab in the back by the accomplices of terrorists" nob head tin pot
[10:04:16] <_methods> https://isotropic.org/papers/chicken.pdf
[10:24:10] <CaptHindsight> looks well researched with plenty of graphs, citations and flow charts
[10:24:57] <_methods> chicken
[10:25:08] <CaptHindsight> looks like a template for research papers
[10:26:04] <_methods> chicken chicken
[10:26:07] <_methods> heheh
[10:36:06] <JT-Shop> how do you monitor network traffic on a linux machine?
[10:36:46] <CaptHindsight> wireshark
[10:37:16] <CaptHindsight> https://www.wireshark.org/
[10:38:22] <archivist> http://www.binarytides.com/linux-commands-monitor-network/
[10:38:32] <JT-Shop> thanks, I'll download it during free time
[10:40:18] <JT-Shop> many to choose from in the morning, thanks
[10:40:49] <CaptHindsight> depends on how much you want to know
[10:44:02] <JT-Shop> I just want to know if any background processes are using the net
[10:45:42] <archivist> all those JS trackers
[10:46:41] <archivist> I started to defend myself against some of the bad adverts and trackers
[10:47:30] <archivist> http://winhelp2002.mvps.org/hosts.htm
[10:47:52] <archivist> I just cherry pick and add them to the hosts file
[10:50:39] <archivist> or check the page with pagespeed see what they do, add entries for adservers
[10:57:13] <FinboySlick> I find tcpdump more straightforward, JT-Shop
[10:57:51] <FinboySlick> JT-Shop: Though if you want to see which process has a socket open, check 'netstat -anp' as root
[10:58:09] <JT-Shop> thanks
[11:22:18] <_methods> wireshark should do the trick though
[11:22:34] <_methods> or tcpdump
[11:24:01] <FinboySlick> _methods: I'm not sure it can tell which process it is (at least tcpdump can't).
[11:24:40] <_methods> oh by process?
[11:24:45] <_methods> ahh
[11:24:48] <_methods> sorry just saw that
[11:25:26] <_methods> nethogs?
[11:25:29] <_methods> i've never used it before
[11:26:05] <_methods> yeah looks like nethogs will display net use by process
[11:28:58] <_methods> looks like ss will work too
[11:38:28] <duc> What's a good brand besides phoenix contacts for terminal blocks
[11:42:24] <Sync> würth
[11:44:13] <_methods> i just buy the chinese ones off ebay
[11:53:05] <CaptHindsight> heh, decided to just fire up wireshark again and noticed that ebay has some persistent connections sans browser
[12:01:58] <zeeshan> duc phoenix contact ftw!
[12:02:01] <zeeshan> i like wago
[12:02:27] <zeeshan> i love the screwless terminal blocks by phoenix
[12:02:36] <duc> I'll have to find a deal on ebay for them
[12:02:54] <JT-Shop> lol wireshark want's to remove linuxcnc
[12:03:27] <zeeshan> wireshark?
[12:04:46] <JT-Shop> ah package manager wants to remove it because it's broken lol
[12:04:56] <zeeshan> hehe
[12:06:24] <_methods> jeebus
[12:08:47] <duc> Now to find the correct terminal block
[12:09:06] <_methods> JT-Shop: you need constant monitoring?
[12:09:17] <_methods> or you just need snapshots?
[12:09:41] <_methods> cause if you just need snapshot of it ss or netstat would do the same thing and they should already be installed
[12:19:24] <JT-Shop> I'd like to monitor it for a while
[12:22:06] <_methods> wireshark is the way to go then
[12:22:50] <_methods> or that nethogs maybe
[12:22:59] <_methods> i think it actually monitors
[12:23:54] <JT-Shop> wireshark is broken on mint :(
[12:24:13] <_methods> ah nethogs monitors
[12:24:22] <_methods> heh cool find
[12:27:28] <FinboySlick> _methods: netstat with the -p option works too.
[12:27:43] <FinboySlick> Oh, to monitor.
[12:27:50] <_methods> yeah
[12:27:56] <FinboySlick> Well, watch -n 0.5 netstat -anp
[12:28:04] <_methods> ah that would do it
[12:28:08] <FinboySlick> Though you probably want to limit that to tcp or udp.
[12:29:17] <_methods> nethogs was in the ubuntu repos
[12:29:18] <FinboySlick> iptables can give you a log of all new connections too.
[12:30:10] <_methods> just did an apt-get install on it
[12:30:16] <_methods> i'm assuming that would work in mint
[12:30:20] <_methods> but........
[12:31:11] <_methods> you know how that assuming thing usually goes
[12:32:02] <FinboySlick> What's the end-goal, JT-Shop?
[12:34:44] <JT-Shop> to find out where all my bandwidth is going
[12:35:38] <FinboySlick> iftop
[12:37:53] <_methods> you should be doing that at the router
[12:43:08] <JT-Shop> well I bought a 8 port router that was supposed to do that but only to find out that it only works on wifi lol
[12:43:34] <_methods> ouch
[12:44:17] <_methods> well if you want to do adv bandwidth management on a network probably not many soho devices are going to work for you
[12:44:43] <_methods> you'll probably need to slap together a pfsense, untangle, or sophos box
[12:44:54] <_methods> roll your own router
[12:45:46] <JT-Shop> wonder what this is leguin.acc.umu.se
[12:45:47] <_methods> i use ntopng on my pfsense router for what you're talking about doing
[12:45:58] <_methods> something in sweden?
[12:46:34] <JT-Shop> dunno, iftop reported it
[12:46:44] <JT-Shop> lol could be the irc
[12:46:58] <_methods> possibly
[12:47:08] <_methods> you have very limited bandwidth correct?
[12:47:37] <JT-Shop> yea, 10gb
[12:47:42] <_methods> with on of those UTM boxes you could set up bandwidth quotas and stuff
[12:48:03] <_methods> s/on/one
[12:48:22] <CaptHindsight> JT-Shop: are you running windows on any of the computers on your network?
[12:48:41] <JT-Shop> two of them
[12:48:53] <JT-Shop> one keeps wanting me to upgrade to 10
[12:49:10] <_methods> i heard they were automatically downloading the update
[12:49:13] <_methods> full windows 10
[12:49:18] <_methods> even if youdidn't tell it to
[12:49:54] <CaptHindsight> windows runs more services and wastes more bandwidth than you can shake a stick at
[12:49:56] <_methods> it is still asking to upgrade but it was already downloading the full install
[12:51:14] <_methods> pretty dirty
[12:51:24] <_methods> especially for people with limited bandwidth
[12:51:55] <CaptHindsight> we had windows on one machine with a game service that was up to 150GB/Mo with its constant updates
[12:52:09] <_methods> jeebus
[12:52:30] <CaptHindsight> now we kill everything that isn't absolutely necessary
[12:53:13] <CaptHindsight> it was Steam
[12:53:30] <CaptHindsight> they treat your bandwidth like it's unlimited
[12:54:03] <archivist> lots of websites doing that too
[12:54:17] <_methods> oh man i installed the steam app on my phone and it killed my phones battery in 45 min
[12:54:19] <CaptHindsight> yeah, run adblock for one
[12:54:51] <maxcnc> hi CaptHindsight you gave me yesterday a idee that workedout today ;-)
[12:55:06] <CaptHindsight> I did?!
[12:55:15] <maxcnc> the papercutter
[12:55:25] <CaptHindsight> ah the slitter
[12:56:11] <maxcnc> the town boss hase been very impressed on the outcome
[12:56:16] <CaptHindsight> maxcnc: happy to be of service
[12:56:34] <_methods> he's sending you the bill now
[12:56:53] <CaptHindsight> first one is free
[12:56:56] <_methods> hahah
[12:58:46] <CaptHindsight> rates are based on category, good idea, just a hunch, I know a guy that said he heard it from someone, popular opinion, unsolicited advice
[12:59:13] <FinboySlick> CaptHindsight <--- techno-pusher
[13:18:03] <Tom_itx> JT-Shop, video your hdd light thru the night on your win box and watch how active it is doing updates
[13:18:48] <Tom_itx> or unplug the cat5 at night :D
[13:21:28] <maxcnc> CaptHindsight: dont ask a Dr on the street it may cost you the shop
[13:22:08] <maxcnc> Alexande1B: ?
[13:30:00] <Tom_itx> CaptHindsight, windows updates is a close race with android
[13:30:38] <JT-Shop> I have updates to ask only, but I'm going to unplug it when not in use
[13:32:14] <Tom_itx> mine are all ask only as well
[13:32:39] <Tom_itx> now if i could get FF to shut up
[13:33:31] <FinboySlick> JT-Shop: Be sure to have a peek at traffic when you plug it back in.
[13:34:30] <JT-Shop> I wonder if there is a way to block internet on windows but keep the lan
[13:34:47] <JT-Shop> prob on the router
[13:34:52] <Tom_itx> use a local ip
[13:35:06] <Tom_itx> or a 2nd router behind the first one
[13:35:16] <FinboySlick> JT-Shop: Just don't provide a default gateway.
[13:35:22] <JT-Shop> I have 3 on the lan now
[13:35:42] <FinboySlick> Set the default gateway to the machine's own ip address.
[13:36:08] <FinboySlick> it will only see the lan
[13:36:21] <FinboySlick> (assuming your lan is a single subnet)
[13:38:10] <JT-Shop> what is single subnet?
[13:38:23] <FinboySlick> 192.168.x.y where only y changes
[13:38:24] <Tom_itx> your local lan
[13:38:40] <FinboySlick> In most 'home router' cases anyway.
[13:38:42] <JT-Shop> yes, that is what I have 192.168.x.x
[13:38:55] <maxcnc> you can alo use 10.0.0.x
[13:39:30] <anomynous_> or 123.123.123.x ;D
[13:39:32] <FinboySlick> If you set no default gateway (only an ip address and subnet mask), the machine will not have anyone to send information to when it wants to go outside the LAN.
[13:39:57] <maxcnc> Gn8
[13:40:04] <Tom_itx> it could go into withdrawal... be careful
[13:40:09] <FinboySlick> But it will still be able to talk to people in the same subnet (ip address range) as its own.
[13:40:10] <anomynous_> i hope he wasn't offended
[13:41:25] <JT-Shop> FinboySlick: that worked I can see the lan but not connect to the internet
[13:41:33] <FinboySlick> JT-Shop: Basically, the 'subnet mask' is a set of bits that tell the machine which bits in the IP addresses it tries to reach are 'local' to it, that is, which ones it doesn't need to go through a router to reach.
[13:41:34] <Tom_itx> anomynous_ on irc? really...
[13:41:40] <anomynous_> yes.
[13:41:51] <anomynous_> people are people on irc too ;)
[13:42:03] <Tom_itx> yeah i agree
[13:42:10] <Tom_itx> that's why i hate social networking
[13:42:20] <anomynous_> maybe irc is asocial networking
[13:42:30] <anomynous_> doesn't count
[13:42:32] <JT-Shop> monkey pickle break over with back to work
[13:43:05] <FinboySlick> JT-Shop: (11111111.11111111.11111111.00000000) tells it, if only the last 8 bits (the last dotted number) change, you're in the same network, don't go through the router.
[13:45:59] <anomynous_> and gateway does network address translation. Your 192.168.x.x never goes out, but your router has two ip addresses. One for local and for public net. And it keeps track of connections and redirects packets and rewrites address data
[14:00:51] <_methods> nah that malcom guy gets butt hurt all the time
[14:00:55] <_methods> so irc is the same lol
[14:03:21] <_methods> just make fun of 3d printers
[14:03:23] <_methods> lol
[14:29:19] <jdh> I got some cool 316ss parts 3d printed
[14:30:28] <_methods> they make guns with them, don't you know
[14:30:39] <_methods> those things are dangerous
[15:12:23] <XXCoder> theres no home like
[15:21:58] <Erant> I don't think I'll ever get these HDPE chips out of my shop.
[15:22:02] <Erant> They cling. :/
[15:22:43] <_methods> stringy bastards
[15:23:30] <XXCoder> try use something to remove charge
[15:23:36] <XXCoder> ionizer or de-ionizer?
[15:26:10] <XXCoder> hmm
[15:26:20] <XXCoder> there is such thing as anti-static brush
[15:26:28] <XXCoder> its usually used for film
[15:28:33] <XXCoder> Erant: apparently grounded foil will work on removing static charge
[15:28:44] <XXCoder> just use long wire to connect to pipes or something
[15:29:03] <XXCoder> then add foil at end and it will remove charge so you can properly sweep it out
[15:29:28] <XXCoder> ionizer would work too
[15:29:52] <XXCoder> ions are stripped atoms, so it suck up electrons, removing any static charge
[15:40:11] <jdh> you are obviously an ionist
[15:40:43] <XXCoder> no, I am a ioneer
[15:41:26] <jdh> you are disregarding negative ions because they don't believe in your god.
[15:41:47] <malcom2073_> No, it's because they're so damn negaitve all the time
[15:41:50] <XXCoder> my god?
[15:41:51] <_methods> what a polarizing conversation
[15:41:52] <malcom2073_> it's an unhealthy environment to be in
[15:41:55] <XXCoder> I AM a Ion god
[15:42:44] <jdh> but only for stripped ones.
[15:42:56] <jdh> you completely dismiss the rest.
[15:43:02] <_methods> heheh
[15:43:15] <XXCoder> yep to belive in me you need to get rid of most or all of electrons!
[15:43:20] <XXCoder> electrons are heretics
[15:45:13] <XXCoder> heh
[15:45:16] <XXCoder> anyway
[15:45:36] <XXCoder> getting a ionizer seem to be good idea if you plan to machine hdpe.
[15:57:44] <tiwake> I'm calling it good at +-0.001"
[16:00:04] <renesis> nooo, electrons are frens!
[16:00:39] <XXCoder> I'm not a jelious god, you can have friends with heretics
[16:26:49] <tiwake> lovely blue chips
[16:27:08] <XXCoder> cutting steel eh
[16:29:40] <XXCoder> :(
[16:29:42] <XXCoder> https://imgur.com/gallery/BsuaJ5K
[16:29:49] <XXCoder> national bullshit now
[16:32:37] <Noxz> is the Hitachi m12vc (with precise colletts) still a great choice for a cnc?
[16:32:45] <tiwake> yeah, cutting steel in the manual lathe
[16:33:07] <XXCoder> cool
[16:33:12] <tiwake> pain in the butt though, gotta turn these things around and bore it for a bearing on the other side too
[16:33:32] <tiwake> so they have to be really square
[16:33:52] <tiwake> which is difficult when the 3-jaw chuck is not quite square
[16:35:18] <XXCoder> plan to use dial indictor and hammer to strighten?
[16:36:27] <tiwake> thats what I did on the first one
[16:36:41] <tiwake> the second one I suspect will need shims though
[16:37:03] <tiwake> doing a little touchup on this one, then its done
[16:37:11] <XXCoder> or ionizer lol
[16:37:15] <XXCoder> jk
[16:37:23] <XXCoder> gonna go work latyer
[16:38:39] <Deejay> gn8
[16:50:45] <tiwake> one is done
[16:50:46] <tiwake> yay
[16:50:49] <tiwake> last one
[16:58:55] <Tom_itx> when i bring in a sub, the mates don't work right :(
[16:59:17] <Tom_itx> they work fine in the original file
[17:12:04] <JT-Shop> I've had that happen from time to time, are you sure all the parts are fully mated, nothing floating about?
[17:16:39] <Tom_itx> pretty sure
[17:17:02] <Roguish> what code are you using? solidworks? or ???
[17:17:09] <Tom_itx> sw
[17:17:27] <jfindley> Can anyone recommend a good 3 axis controller for EMC2?
[17:17:50] <Tom_itx> jfindley, what do you mean by 'controller' ?
[17:18:14] <Roguish> Tom_itx: do you have any of the 'centered' type mates? sometimes they cause numeric instability.
[17:18:24] <Tom_itx> concentric, yes
[17:18:38] <jfindley> Motor driver/controller I suppose, something EMC2 can communicate with in order to do some milling
[17:19:14] <Tom_itx> jfindley, pc -> mesa card -> amp -> motor
[17:20:05] <Roguish> that could do it if you have more than 1. the program 'hunts' for a center. 1 usually is cool. more can cause instability. especially if you try to move stuff around.
[17:20:46] <Roguish> if you get it centered, try and 'fix' it in place.
[17:21:16] <Roguish> and be glad it's SW, not ProE. way worse.
[17:24:11] <jfindley> Tom_itx: Can you elaborate? I currently use a TinyG but I want something a little better that I can use with EMC2.
[17:24:32] <Tom_itx> stepper or servo?
[17:24:49] <jfindley> steppers, 3 NEMA 17s for X, Y, and Z travel.
[17:26:19] <Tom_itx> http://store.mesanet.com/index.php?route=product/product&filter_name=7i76&product_id=215
[17:27:10] <JT-Shop> well my two deer pets made it through gun season :)
[17:27:15] <tiwake> I really don't like this chuck
[17:27:51] <JT-Shop> Tom_itx: I can look at in the morning during free time if you want to post it
[17:28:08] <Tom_itx> it's just a learning practice...
[17:28:12] <Tom_itx> i'll figure it out
[17:28:23] <Tom_itx> the real problem is in catia
[17:28:26] <JT-Shop> ok
[17:28:31] <Tom_itx> and it's not my problem, it's my kids :D
[17:28:43] <JT-Shop> jfindley: nema 17's won't take much to drive them
[17:28:55] <Tom_itx> i've been drawing all his lessons in sw to learn it better
[17:29:03] <Tom_itx> and help him along the way
[17:29:04] <JT-Shop> cool
[17:29:26] <Tom_itx> now he's in 'assemblies' class
[17:31:43] <JT-Shop> when the salesman came to demo sw all those years ago, I cut him off 1/2 way with I've seen enough, boy did he have that look till I said I'll take a copy
[17:32:07] <Tom_itx> hah
[17:32:20] <JT-Shop> jfindley: what's your location?
[17:32:52] <Tom_itx> i see it's quite picky about what you pick for the constraints
[17:33:08] <JT-Shop> 4 more pcs of garage door trim to put up
[17:33:27] <Roguish> catia is formidable. it's big time. aerospace and automotive. Tesla uses it out here.
[17:33:34] <JT-Shop> yea you don't want to over mate or under mate parts
[17:34:10] <JT-Shop> I'll often draw construction lines on the parts and mate to them, usually faster
[17:37:41] <JT-Shop> looks wet for me thur - mon
[17:38:29] <JT-Shop> Roguish: I tried mint cinnamon and didn't care much for it... too much controlling
[17:39:51] <Roguish> I am working on it again. had to move partitions and stuff around yesterday. my RT-preemt build ran our of disc room.
[17:40:10] <JT-Shop> did you say you had a script from pcw?
[17:40:37] <Roguish> yeah, sort of going thru it now. I started with the 64 bit MINT
[17:43:20] <Roguish> what's the main difference between Mate and Cinnamon? anything really substantial or just fluff?
[17:43:54] <JT-Shop> I loaded Mate this morning but have not looked at it yet, I did run Mate on debian
[17:44:12] <JT-Shop> I've been running Xfce
[17:44:26] <jfindley> JT-Shop: I'm in Houston
[17:45:22] <JT-Shop> ok, us then I'm partial to gecko drives for steppers
[17:45:58] <JT-Shop> but there are others, just beware of the tb6560 it can be a smoker if you hot plug anything
[17:46:07] <Roguish> Mate, Cinnamon, and Xfce are display managers. right? I think one can change pretty easily between them, on the same system like Mint.
[17:46:15] <JT-Shop> yea
[17:46:39] <JT-Shop> I just installed one of each to test out
[17:47:21] <jfindley> Roguish: Xfce is my favorite behind KDE.
[17:47:33] <_methods> +1 for xfce
[17:47:36] <JT-Shop> if it comes to it I'll run openbox on debian, it's not too bad
[17:48:02] <JT-Shop> too bad xfce has a menu editor bug for the last few releases
[17:48:31] <Roguish> Mate seems ok so far. I think LightDM is pretty good. It's a machine controller, not a juke box or game console, or word processor.
[17:48:53] * JT-Shop puts on the chef hat and heads inside to cook chili con carne
[17:48:56] <Roguish> something fast and low overhead.
[17:49:40] <JT-Shop> I do programming and the docs so I need a few more things on at least on pc, but yea for a machine you just need the basics
[17:49:52] <jfindley> JT-Shop: I guess I'm having trouble seeing how EMC2 can control a CNC machine. I assume EMC2 takes Gcode and translates that based on some configuration into signals piped over a parallel port to a "controller" which takes those signals, maybe does some filtering, and sends them to the motors, right?
[17:50:01] <JT-Shop> too bad you can't just roll your own...
[17:51:40] <JT-Shop> http://linuxcnc.org/docs/2.7/html/user/user-intro.html
[17:51:42] <jfindley> JT-Shop: The TB6560 seems like what I'm after, in that I think all I need to make it work is a parallel port card, and that controller.
[17:51:47] <Roguish> JT: get cookin' !!! go man. daylight is burning.
[17:51:59] <JT-Shop> daylight is gone my friend
[17:52:09] <JT-Shop> jfindley: http://linuxcnc.org/docs/2.7/html/user/user-intro.html
[17:52:10] <Roguish> not here yet.
[17:57:54] <tiwake> JT-Shop: cant say I've ever gotten a scar from machining
[17:58:27] <tiwake> plenty of cuts though
[17:58:27] <tiwake> never bad enough to scar
[17:58:28] <greg_> I've been running a home brew mill with geckos for 10 years directly from a parport.
[17:59:01] <greg_> all depends on what you're trying to do.
[17:59:42] <greg_> this time on a Lathe I'm going with Mesa.
[17:59:50] <tiwake> I'm kinda curious though, can linuxCNC be set up to have a forced feedback sort of thing when in, say manual mode?
[18:00:18] <jfindley> JT-Shop: So bascially, I could use a G540 and be done with it? All I would need is a parallel port card and a power supply?
[18:00:22] <Tom_itx> Roguish, they use catia almost exclusively here now
[18:00:42] <Roguish> where's here?
[18:00:55] <jfindley> http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html
[18:00:57] <Tom_itx> Ks
[18:01:02] <Tom_itx> 'air capitol'
[18:01:13] <Roguish> Kansas City?
[18:01:16] <Tom_itx> Wichita
[18:01:45] <Tom_itx> cessna, beech, bombardie, spirit (boeing) etc are all here
[18:02:03] <Roguish> ok. yeah, Catia is big in aerospace. I touched it years ago at Hughes Aircraft on a satelite
[18:02:27] <Tom_itx> i considered taking it myself
[18:02:42] <Tom_itx> although i probably wouldn't go job hunting
[18:02:43] <Roguish> was job shopping there. a friend from back then is in KS or thereabouts working aircraft. he's a stress guy.
[18:03:09] <zeeshan> :D
[18:03:37] <Tom_itx> zeeshan figured you'd pop up if the right key word was typed
[18:03:41] <zeeshan> haha
[18:03:53] <zeeshan> i just got home from work
[18:03:55] <zeeshan> starting other job soon :P
[18:04:02] <zeeshan> eating some beef jerky
[18:04:05] <Roguish> like i said, Tesla uses it for design: www.teslamotors.com
[18:04:31] <Tom_itx> i think andy said ford uses it
[18:05:15] <Roguish> send your boy out. he can join the others at Tesla doing 70+ hours a week. Keeping Musk's promises.
[18:05:16] <greg_> g540 might do what you want, but O
[18:05:19] <Akex_> Hy all
[18:05:20] <Tom_itx> i think it's a good thing to have under your belt just starting out
[18:05:46] <Tom_itx> he finishes this semester, he's guaranteed an interview with spirit
[18:05:59] <Roguish> Tom_itx: best is that if you know one code well, the others are easy to pick up. they all do the same thing.
[18:05:59] <greg_> I'm not familiar with it. You still might want limits, homing, spindle etc.
[18:06:00] <Akex_> Andy what is your website for the mother board only 12V psu
[18:06:02] <zeeshan> imagine if he trained on freecad
[18:06:03] <zeeshan> :-)
[18:06:05] <Akex_> andypugh:
[18:06:13] <Tom_itx> Roguish, i know
[18:06:27] <Tom_itx> i've been using smartcam quite a while
[18:06:42] <Tom_itx> learning sw a little now and then
[18:06:46] <Tom_itx> hate acad
[18:07:16] <Roguish> the whole object is to make lines on paper and get something manufactured to sell to the masses, and ACAD is the greatest!!!!
[18:07:29] <Tom_itx> hah
[18:07:39] <Roguish> Autodesk sold 1 copy of acad to China.....
[18:07:43] <Tom_itx> the fusion looks interesting
[18:08:36] <Roguish> check this. it's safe: www.warezstore.com
[18:08:37] <Tom_itx> they still use paper?
[18:09:00] <zeeshan> Tom_itx: finish this job plz
[18:09:09] <Tom_itx> what job?
[18:09:31] <zeeshan> some aluminum parts
[18:09:32] <zeeshan> =/
[18:09:39] <zeeshan> i got tired last night, couldnt finish em all
[18:09:43] <zeeshan> put the machine in horizontal mode
[18:09:47] <Tom_itx> hire a monkey
[18:09:48] <zeeshan> and called it a night :P
[18:10:05] <Tom_itx> he'll screw up the part on the last op
[18:10:29] <zeeshan> lol
[18:10:40] <zeeshan> ive been talking to a good friend of mine
[18:10:46] <zeeshan> i might invest in a shop w/ him
[18:10:52] <zeeshan> and work there part time
[18:11:00] <zeeshan> offering eng and prototyping services
[18:11:06] <zeeshan> not sure yet :p
[18:11:23] <zeeshan> having your own business seems like a good way to die early :P
[18:11:41] <Roguish> how to make a large fortune into a small fortune.....
[18:12:58] <Tom_itx> depends how you manage it
[18:13:17] <Tom_itx> and yes you will work more hours
[18:14:07] <Tom_itx> zeeshan, does he do machining?
[18:14:15] <zeeshan> a bit
[18:14:21] <Tom_itx> what's he best at?
[18:14:24] <zeeshan> there will be 3 of us
[18:14:30] <zeeshan> all are mech eng, but he's good with marketing and sales
[18:14:53] <Tom_itx> good at marketing aka killing the machinist on deadlines
[18:14:57] <zeeshan> lol
[18:15:05] <zeeshan> i think we'll hire a machinist if it gets busy
[18:15:10] <zeeshan> thats the plan in paper
[18:15:22] <Tom_itx> well good luck with that
[18:15:47] <Tom_itx> i've described this area several times... my friend couldn't buy good help
[18:17:33] <Tom_itx> it could work if you do it right
[18:18:01] <Sync> hm, just got a microscope, spent the day looking at things
[18:18:10] <Tom_itx> binocular?
[18:18:16] <Tom_itx> they're quite handy
[18:18:42] <Sync> trinocular, otherwise it is pretty useless
[18:18:52] <Tom_itx> taking pics too?
[18:19:06] <_methods> insect porn
[18:19:16] <Tom_itx> binocular is pretty handy for soldering smt parts
[18:19:21] <Sync> http://sync-hv.de/~tmp/mcm6664_1.jpg
[18:19:27] <Tom_itx> that's what i got mine for
[18:20:02] <_methods> dayum
[18:20:08] <_methods> i'll take one plz
[18:20:09] <Tom_itx> image cannot be displayed
[18:20:25] <_methods> how much was that damn scope
[18:21:33] <Sync> not terribly expensive, paid 520€ for it
[18:21:47] <zeeshan> what is that sync
[18:21:47] <Tom_itx> mine was ~3
[18:22:05] <Tom_itx> some computer chip
[18:22:10] <_methods> what scope is it?
[18:22:28] <_methods> i've been wanting to get a good scope for awhile
[18:23:24] <Tom_itx> mine is from amscope
[18:23:36] <Tom_itx> 7 x 45 zoom
[18:23:45] <Sync> zeeshan: look at the right
[18:23:47] <Tom_itx> the zoom is a must for prattical use
[18:23:49] <Sync> it is some old ass ram
[18:24:00] <Sync> I never found zoom to be useful
[18:24:13] <Sync> I just have a 2x 4x and 8x for my mantis
[18:24:15] <Tom_itx> pretty sure mine would show about the same
[18:24:23] <_methods> is that pic from the mantis?
[18:24:31] <Sync> no
[18:24:56] <Sync> yeah, that was just a quick attempt
[18:26:11] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/scope/scope1.jpg
[18:26:59] <_methods> one day i'll get one

[18:28:01] <Tom_itx> that's a different base than mine
[18:28:16] <andypugh> Akex_: http://www.mini-itx.com/store/?c=34#JNF9C-2800
[18:28:56] <Akex_> Thx andypugh ;)
[18:29:20] <Akex_> Andy your youtbe chanel is awesome !!!
[18:29:41] <andypugh> Thanks
[18:30:31] <andypugh> Talking of microscopes, I used to work for a company that made Xray microscopes. Those can produce images like that chip one, without damaging the encapsulation.
[18:31:35] <Sync> well for scoping out the metal layers xray works pretty well
[18:31:43] <Sync> I need to get a microfocus xray source
[18:31:50] <andypugh> The picture here is a CT scan of BGA balls, in-situ after soldereing: http://www.nordson.com/en/divisions/dage/products/x-ray-inspection-systems/computerized-tomography-option
[18:32:50] <Sync> Tom_itx: you can't take a picture like that with that one as you cannot do dark field illumination
[18:34:37] <Sync> I'm wondering if I really need to get the DIC setup
[18:36:41] <andypugh> Anyway, early start tomorrow
[18:41:37] <Noxz> is the Hitachi m12vc (with precise colletts) still a great choice for a cnc?
[18:41:56] <Noxz> a cnc tool
[18:44:52] <Roguish> andypugh: there is a Zeiss division just here that makes Xray scopes, also.
[18:53:12] <Tom_itx> Sync, yeah i know. i didn't get it for that
[18:57:34] <Tom_itx> zlog
[19:00:12] <_methods> wow syfy didn't butcher the expanse
[19:00:48] <Tom_itx> i don't think sw likes my mates
[19:01:25] <Tom_itx> i did that distance one on the piston then joined the piston housing to the base and the piston quit moving
[19:28:56] <Tom_itx> JT-Shop, i just took the parts i had put in the sub and put them in the main with slightly different mates and it seems to be working now
[20:20:18] <Jymmm> Damn, check out the pics at the bottom... http://www.huffingtonpost.ca/2015/01/16/bc-woman-northern-food-crisis_n_6408508.html
[23:35:47] <Crom> anyone know a channel for K40 laser cutters?
[23:36:10] <Crom> I just saw one on ebay for $397 shipped
[23:38:08] <Crom> seen Duc_mobile
