[00:04:58] <Jymmm> MacGalempsy: congrats?
[00:05:06] <MacGalempsy> heh
[00:05:22] <MacGalempsy> x and y are homed fine, but the z is being a problem
[00:05:56] <MacGalempsy> I have tried a couple of solutions in the forums, but all have failed
[00:06:18] <MacGalempsy> the wierd part is one time it worked fine, then rehoming it failed again
[00:06:44] <Wolf_> no error message? just shuts the machine power off?
[00:07:18] <MacGalempsy> it hits the endstop then states Joint_2 following error
[00:12:02] <MacGalempsy> http://www.pastebin.com/bTPXXM0f
[00:12:39] <MacGalempsy> if someone has a moment to look at this INI clip and tell me what I may be doing wrong, it would be appreciated
[00:18:05] <Jymmm> you're running servos?
[00:18:53] <MacGalempsy> yes
[00:19:35] <Jymmm> Okey, way beyonf my paaygrade, but I'm sure someone in the moring can help.
[01:39:57] <archivist> MacGalempsy, separate home and limit switches?
[01:40:40] <archivist> are they far enough apart, ie is there some over travel due to tuning hitting the limit
[02:19:43] <Deejay> moin
[06:27:43] <ganzuul> LTL transport of that ~450lbs ssi-sized lathe from GA,USA to Turku, Finland would cost about 360 euros. That's about a 10th of what Fedex wanted.
[06:42:03] <malcom2073> wow, that's... *really* cheap
[06:44:49] <Deejay> yeah, sounds pretty cheap for me too
[06:48:59] <malcom2073> Also: is ssi really that fat?
[06:50:05] <XXCoder> social security insurance is that big
[06:50:08] <XXCoder> heh
[06:50:15] <malcom2073> heh
[06:50:41] <XXCoder> talking about big stuff, one bridge was once shipped from usa to uk
[06:51:01] <XXCoder> it was famous for something or other and trhey planned to destroy it, so someone at uk wanted it
[06:51:09] <malcom2073> I seem to recall something about that
[06:51:29] <malcom2073> Think I saw that on a documentary or something
[06:53:32] <XXCoder> yeah cant remember more
[06:59:42] <ganzuul> This site auctions LTL transports: http://www.uship.com/eu/delivery/Price-quote/876968535/?authtoken=CMV6RFWTAFC34&bid=18744598#18744598
[06:59:45] <ganzuul> derp
[06:59:54] <ganzuul> https://www.uship.com/eu/
[07:00:46] <ganzuul> Does the previous link work for you guys?
[07:04:23] <ganzuul> If so, send me a lathe! :D
[07:11:36] <malcom2073> Nice
[07:12:40] <Jymmm> if not, ganzuul will send you a lathe ADN mill, CNC Ready out of the box!
[07:12:46] <Jymmm> AND*
[07:13:24] <malcom2073> woohoo!
[07:16:08] <malcom2073> Hmm, auction closing today... should I bid on more useless crap I don't really need?
[07:16:26] <Jymmm> auction for what?
[07:16:38] <malcom2073> Random stuff, some welding fab place closing down near me
[07:17:00] <malcom2073> Couple of "bridgeport 6" vice"'s, random electric motors,
[07:17:32] <Jymmm> Do you have a NEED for any of it?
[07:17:35] <malcom2073> I might?
[07:17:45] <Jymmm> Do you have a CURRENT NEED for any of it?
[07:18:05] <malcom2073> Heh, depends on your definition of current :P
[07:18:14] <malcom2073> Actually there are two half full holddown sets in there
[07:18:19] <malcom2073> I may bid on them, I'll need holddowns for the mill
[07:18:27] <Jymmm> malcom2073: Yes, you should overbid by $1000 too
[07:18:52] <Jymmm> malcom2073: Make it $10,000 unstead
[07:18:56] <malcom2073> Hah
[07:18:59] <Jymmm> instead*
[07:18:59] <malcom2073> if I had that kind of money laying around :P
[07:19:22] <archivist> XXCoder, london bridge, went the other way iirc
[07:19:34] <Jymmm> Oh, it doens't matter if you have the money, just a smartass tax to drive you into poverty
[07:19:44] <malcom2073> heh
[07:34:52] <ganzuul> OKAY
[07:35:00] <ganzuul> Order confirmed. :D
[07:35:09] <ganzuul> For the 7x lathe.
[08:10:50] <lair82> Good Morning Guys, has anyone tried to create an xorg.conf file on the debian wheezy software? I have done this before on one of my ubuntu machines, but It keeps giving me a fault on this debian machine.
[08:11:25] <cpresser> yes, i have done this. whats the fault?
[08:11:42] <cpresser> (will answer in ~30min, got to grab some food)
[08:12:29] <lair82> cpresser "number of created screens does not match number of detected devices"
[08:13:49] <Jymmm> add 20 more monitors!!!
[08:13:55] <Jymmm> problem solved
[08:14:31] <lair82> :(
[08:14:43] <Jymmm> lair82: 30 more???
[08:14:58] <lair82> lol
[08:15:10] <lair82> rofl
[08:15:17] <Jymmm> lair82: JUMBOTRON... 104 FOOT big screen =)
[08:15:54] <Jymmm> and hope that it's not a TOUCH screen
[08:16:03] <lair82> just adding 10 more monitors would cost more than what the machine is worth
[08:16:19] <Jymmm> and your point is?
[08:16:50] <Jymmm> lair82: Have you not seen $1200 cars with $40,000 sound systems in them???
[08:16:52] <ganzuul> The issue might be device detection, not created screen.
[08:16:56] <ganzuul> ~screens

[08:17:45] <lair82> The connection was interrupted The connection to forums.freebsd.org was interrupted while the page was loading.
[08:18:09] <lair82> Very true Jymm
[08:18:14] <lair82> Jymmm
[08:19:36] <lair82> ganzuul, I keep seeing this in the search results, but it keeps denying me
[08:23:14] <ganzuul> Weird! Can you use the google cache function?
[08:24:55] <ganzuul> What about TOR?
[08:28:50] <lair82> the cache function worked,
[08:29:14] <ganzuul> ah
[08:29:24] <ganzuul> I just rehosted it on my private server... http://nya.dy.fi/static/xorg%20issue/Number%20of%20created%20screens%20does%20not%20match%20number%20of%20detected%20_%20The%20FreeBSD%20Forums.htm
[08:37:35] <lair82> I read through it , I disabled the onboard graphics already in the bios, and this has radeon graphics on it, but those shouldn't matter if I disable it in the bios
[08:47:59] <cpresser> lair82: open the config file
[08:48:38] <cpresser> lair82: and clean it; the autoconfig creates one entry for each possible gfx driver (up to 4 for each card). strip them down to one
[08:49:06] <lair82> Which config file?
[08:49:13] <cpresser> xorg.conf
[08:49:33] <lair82> As far as I can tell, I dont have one
[08:49:55] <cpresser> didnt you say you created onw ith autoconf?
[08:51:00] <lair82> No, I tried to create one with the Xorg -configure command with lightdm stopped, in the console, and it comes up with the fault.
[08:51:33] <lair82> I just did a file search of the entire disk, and there is no xorg.conf file
[08:51:41] <cpresser> check it if created a file in the current directory
[08:52:00] <cpresser> i can remember also seeing some error when trying to run Xorg -configure
[08:52:49] <lair82> I am not seeing one
[08:54:41] <lair82> I tried "sudo gedit /etc/x11/xorg.conf" and that says " cannot open display "
[08:55:39] <lair82> I might be waiting for my new MB to come in on monday,
[08:57:12] <lair82> I looked again, and cannot find any xorg.conf file anywhere
[09:05:44] <cpresser> why gedit? it wont work without Xog running
[09:05:49] <cpresser> use vim or nano on the console
[09:06:38] <lair82> Xog?
[09:12:53] <malcom2073> Xorg*
[09:13:53] <lair82> how do i start xorg
[09:15:01] <malcom2073> restart lightdm
[09:15:10] <malcom2073> it'll automatically start it
[09:15:24] <malcom2073> Or, just use vim/nano in the console
[09:24:48] <lair82> Ok, so I ran sudo vim /etc/X11/xorg.conf and a black screen pops up with ~ all the way down the left side, and "/etc/X11/xorg.conf" [New File], at the bottom.
[09:26:50] <cpresser> well, then the file does not exist ([New File])
[09:27:01] <cpresser> exit vim with ":q!"
[09:33:29] <lair82> Ok, just exited
[09:35:27] <lair82> I just wonder if I am chasing a ghost, Do you think this will help get my latency down to a respectable number? Or would I be better off waiting for my new MB and CPU on monday?
[09:35:40] <ssi> lair82: what did you change?
[09:35:42] <archivist> CaptHindsight, a sense of scale http://www.hexagonmetrology.us/component/content/article?id=487:new-venture-gear-saves-millions-with-pcrs
[09:37:36] <ssi> god these questions are dumb
[09:37:40] <ssi> true or false: "A discontinuity may or may not affect the usefulness of a part."
[09:37:54] <lair82> I re-installed debian late yesterday, got all the updates finished up this morning, and re-compiling. It was looking ok in regards to the latency number ( around 14000 servo period) and then I went back and checked and it was at 290000.
[09:37:58] <ssi> I should make a test that the faa test writers have to pass before they can make these stupid tests
[09:38:09] <ssi> true or false: "A dichotomy is always true"
[09:38:16] <cpresser> lair82: it might help alot. but if you are 'this new to linux' it might take you a while to do it. waiting till monday isnt that bad either
[09:39:12] <cradek> lair82: ouch, that's not good
[09:39:36] <archivist> ssi I suppose you have to think like some faa safety idiot for the right answer
[09:39:59] <ssi> true or false: "the previous question is or isn't useful in any way"
[09:40:45] <_methods> heheh
[09:41:00] <archivist> I had some silly questions at the Open University, q1 what is Not A, q2 what is not B
[09:41:03] <_methods> worst test i've ever taken was the EMT Paramedic test
[09:41:13] <CaptHindsight> ssi: that sounds pretty typical for any test I've seen
[09:41:13] <_methods> every question had more than 1 right answer
[09:41:21] <_methods> and you had to pick the most correct oen
[09:41:22] <_methods> one
[09:41:27] <_methods> was a real PITA
[09:41:31] <ssi> _methods: yeah well there's a lot of those on this test too
[09:41:34] <CaptHindsight> more corrector
[09:41:47] <_methods> and each question after was dependent on teh questions before
[09:41:59] <_methods> so if you got the first one wrong you'd get the rest in the series wrong
[09:42:02] <ssi> ha
[09:42:49] <_methods> somehow i got 87% on that one
[09:43:15] <_methods> but probably one of the few tests i've taken where i left the room without any idea if i'd passed or not
[09:43:30] <_methods> usually you know if you did well or not
[09:43:36] <_methods> but not that monstrosity
[09:44:29] <ssi> I got 90 and 92 on my two full-length A&P general practice tests last night
[09:44:31] <_methods> i think only 20% of the class passed first try hehe
[09:44:32] <ssi> and a 97 on a half one
[09:44:39] <ssi> doing another full one now, I think I have this one licked
[09:44:45] <ssi> then I have to move on to powerplant
[09:45:07] <_methods> so what is this testing for?
[09:45:09] <_methods> inspections?
[09:45:16] <ssi> mechanics license
[09:45:19] <CaptHindsight> part of the test is on how well socialized you are, have you memorized what is expected and do you respond accordingly
[09:45:22] <_methods> ahh
[09:45:38] <ssi> gotta have and use an A&P for 3 years before you can apply for inspection authorization
[09:45:44] <ssi> and the IA is reportedly a bitch
[09:46:02] <ssi> CaptHindsight: all the faa tests are passed via memorization sadly
[09:46:08] <ssi> I actually want to know the material so I'm reading the books
[09:46:18] <ssi> but at the end of the day the only practical way to do well on the tests is memorize the answers
[09:46:30] <CaptHindsight> they aren't designed around critical thinking, there's lots of stimulus with proper response
[09:46:34] <ssi> because there's enough trick questions and stupid bullshit questions that you can't count on doing well by being smart alone
[09:47:00] <ssi> most of you in here would actually do pretty well on the General test
[09:47:16] <ssi> lots of math, physics, EE, etc
[09:47:27] <ssi> not so much specific aircraft stuff, that stuff is on the airframe and powerplant tests
[09:50:15] <lair82> I just don't want to sit for too much longer, I am at the customers, and I don't want to hit his bill too much harder for my mistake on the MB/CPU problems.
[09:50:31] <ssi> lair82: just wait for new mb/cpu then
[09:51:22] <lair82> If I were at the shop on my machine, I wouldn't care, I could work on other things while waiting for help from you guys.
[09:51:43] <lair82> Which I am grateful for
[09:51:54] <ssi> lair82: I'm guessing you're on the release packages of linuxcnc now?
[09:53:39] <cradek> lair82: if you're waiting for an answer to a question, it's not clear to me what that question is
[09:53:50] <cradek> granted, it might just be me :-)
[09:53:58] <ssi> I'm not sure what the question is either
[09:54:10] <cradek> ok, it's you, lair82
[09:54:12] <cradek> haha
[09:54:17] <ssi> is it possible to get that particular machine to not have latency problems? maybe
[09:54:21] <lair82> I haven't made it that far, I was setting up the network interface and noticed the latency spiked again
[09:54:40] <ssi> can we tell you how to do it via irc in a small amount of billable time for your customer? probably not
[09:55:09] <ssi> god this test is the worst
[09:55:09] <ssi> Solve the equation.
[09:55:10] <ssi> 4 - 3[-6(2+3) + 4]
[09:55:19] <ssi> the answer I come up with isn't one of the choices
[09:55:20] <ssi> naturally
[09:55:51] <lair82> cradek, I was trying to setup the xorg.conf file on this debian machine to use the vesa driver, but I keep getting faults, and there isn't any real help googling for it.
[09:56:04] <lair82> To try to get the latency down
[09:56:20] <malcom2073> ssi It'd be -74 yeah?
[09:56:28] <ssi> that's what I kept coming up with
[09:56:36] <ssi> but no I think it's actually 82, which is one of the answers
[09:56:44] <malcom2073> -26 ?
[09:57:23] <lair82> pcw gave me the info on the MB/CPU he has had debian on, running a 7i80 24/7 for almost a year, without a single hiccup, so I ordered it, and it will be here monday
[09:57:26] <ssi> the gubmint has to make sure you understand order of operations in improperly formatted equations :)
[09:57:40] <_methods> -24
[09:57:55] <_methods> oops 26
[09:57:55] <ssi> lair82: since tinkering with it isn't free, I say set it aside and start fresh on the new hardware
[09:57:56] <_methods> yeah
[09:58:13] <lair82> thats what im doing
[09:59:06] <malcom2073> -26 is correct if []'s mean (do the addition first)
[09:59:10] <lair82> Thank you guys for all the help
[10:00:02] <cradek> haha
[10:00:09] <cradek> you guys
[10:00:34] <lair82> ?????
[10:00:36] <malcom2073> I seriously don't remember what the []'s mean
[10:00:43] <_methods> foil
[10:00:43] <malcom2073> Must be something silly
[10:00:44] <ssi> [] is just () but nested
[10:00:51] <_methods> lol
[10:00:53] <cradek> I get 4pi/3
[10:01:29] <cradek> lair82: sorry I meant about the silly math problem
[10:02:13] <_methods> 82
[10:02:15] <lair82> Oooohhh
[10:02:18] <ssi> 82 is right
[10:02:41] <_methods> 4 + -3[-6(5) + 4]
[10:02:45] <_methods> combine like terms
[10:02:51] <_methods> 4 + -3[-30 + 4]
[10:02:58] <_methods> 4 + -3[-26]
[10:03:05] <_methods> 4 + 78
[10:03:25] <pcw_home> 100?
[10:03:54] <ssi> ugh here's another one
[10:03:55] <ssi> [(4 x -3) + (-9 x 2)] 'divided by' 2
[10:03:57] <pcw_home> oh reading back, eq changed
[10:03:59] <ssi> since when is 'divided by' an operation
[10:04:43] <cradek> pcw_home: I got 100 at first too, because I got 3+2 wrong
[10:05:03] <ssi> tripped up by the hard spots :D
[10:05:06] <pcw_home> well since I cant add I better give up now
[10:05:07] <_methods> -15
[10:05:27] <ssi> I kept getting -74 on the first one because I was neglecting one of the signs
[10:05:44] <ssi> math is hard guyse
[10:06:24] <cradek> 4 2 3 + _6 * 4 + 3 * - p
[10:06:24] <cradek> 82
[10:06:34] <ssi> oh god cradek's gone full RPN on us
[10:07:37] <cradek> if everyone used RPN you'd not all be grousing about parentheses
[10:07:55] <ssi> yeah we'd all just be shuffling through life sans-math :D
[10:11:23] <lair82> does anybody have any info on building/running using the buildbot?
[10:11:43] <cradek> lair82: for a customer, use released versions, not buildbot versions
[10:12:18] <cradek> however, the instructions you're asking for are on the front page of buildbot.linuxcnc.org
[10:12:24] <lair82> Can I use 2.7 on debian wheezy, and run the 7i80?
[10:12:33] <cradek> sure
[10:12:37] <cradek> use 2.7.0
[10:13:31] <pcw_home> whats the magic invocation on 2.7 to get the uspace version/kernel?
[10:13:40] <lair82> So I can still use the command line and compile, just using a released version not "master"?
[10:13:56] <cradek> (untested??) apt-get install linuxcnc-uspace
[10:14:07] <cradek> why are you compiling?
[10:14:39] <pcw_home> apt-get install linuxcnc-uspace should be all you need
[10:15:17] <pcw_home> plus reboot to get new kernel
[10:16:47] <pcw_home> I'll have to try this, not sure if the install does the proper grubbery
[10:17:54] <cradek> err, you have to change the source from 2.7-rtai to 2.7-uspace
[10:17:58] <cradek> trying it here now
[10:18:58] <cradek> yeah, looks right
[10:22:02] <cradek> beware: after you do that, the rtai kernel is still the default
[10:22:15] <lair82> cradek, pcw_home, here is what I put together awhile ago, that I go by, when using debian and a 7i80, http://pastebin.com/6Qk9566G
[10:23:01] <lair82> and if it is wrong, I am up for corrections.
[10:23:04] <cradek> that's all pretty much wrong now
[10:23:17] <lair82> Of course it is,,,
[10:23:31] <cradek> open synaptic, change the package sources from 2.7-rtai to 2.7-uspace, then install the linuxcnc-uspace package and reboot
[10:25:29] <cradek> then you might want to remove the linux-image-3.4-9-rtai-686-pae package
[10:27:23] <cradek> I guess it's called Settings/Repositories in synaptic
[10:30:34] <lair82_> http://postimg.org/image/qeccyiuzz/
[10:30:52] <lair82> cradek, that is what I am seeing
[10:31:09] <lair82> Should I make a new thumb drive image?
[10:32:18] <cradek> on those checked wheezy lines, change 2.6 to 2.7-rtai
[10:32:37] <cradek> on those checked wheezy lines, change 2.6 to 2.7-uspace
[10:32:40] <cradek> oops
[10:39:13] <lair82> where are the current install instructions to use synaptic to build linuxcnc?
[10:40:51] <ssi> I may be missing something, but is there a reason you can't just use the apt packages?
[10:44:05] <lair82> I just don't see any where on here http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC on how to install Linuxcnc when using Debian Wheezy,
[10:44:43] <lair82> That is why I have always used the terminal, building from the source
[10:45:48] <ssi> you install it from packages on debian the same way you do on ubuntu: by adding the appropriate repo to your sources list and installing via apt-get
[10:46:03] <ssi> the followup question is, is there a reason you need debian?
[10:46:27] <ssi> furthermore, isn't the livecd debian these days?
[10:46:45] <lair82> I am using a mesa 7i80, I need uspace
[10:46:55] <ssi> ok
[10:47:35] <lair82> My three turning centers are using 5i23's, on ubuntu. I know those like the back of my hand.
[10:48:23] <lair82> I will have to continue this later, I have to get back to the shop, machine down
[10:48:27] <lair82> Thanks guys
[11:09:08] <ganzuul> I'm sure m stuff will arrive soon. http://i.imgur.com/6QSdWiR.gif
[11:14:12] <Jymmm> For you hot glue gun freaks... http://www.frys.com/product/8235146
[11:17:57] <_methods> looks like a paper shredder
[11:18:32] <_methods> are 3d printers still a thing?
[11:19:18] <Jymmm> Maybe they're like pet rocks, just a fad
[11:19:19] <ganzuul> Industry is starting to use them for fixtures.

[11:22:53] <malcom2073> "When you wanna look like geordi from the rear"
[11:39:36] <SEL> hi
[11:40:29] <SEL> I am trying spindle control, started with this http://linuxcnc.org/docs/html/examples/spindle.html#_0_10v_spindle_speed but it is unclear to me what is my DAC pin name
[11:40:57] <lair82> Back to the install questions, If I follow, the section "3.7.1 Installing on Debian Wheezy and Debian Jessie (with Preempt-RT kernel)" in the " Getting Started ' manual, that should be all I need to take a bare install of debian wheezy, and be making chips?
[11:41:28] <lair82> Installed with the iso off of the linuxcnc website.
[11:41:56] <cradek> I already told you how to switch the linuxcnc iso from rtai to uspace - if these instructions are the same as what I said, yes they are right
[11:42:15] * Loetmichel embedded a fat sliver from a wooden pallet into his thumb today at work while unloading a delivery truck... MAN was that bleedingfor half an hour ... painted my surroundings with red dots for sure... lets see if it gets inflamed tomorrow ;-)
[11:43:31] <cradek> I'm not going to make some promise about being all you need to make chips
[11:43:45] <lair82> I saw what you said earlier, about changing to uspace, I am just not sure on how to proceed from there. Every time I have set a machine up, I have used what I posted earlier.
[11:43:45] <cradek> I feel like you are not accepting/trying my answer - why not? am I missing something?
[11:44:13] <ganzuul> Loetmichel: Conifer resin works wonders on infected wounds, for some reason.
[11:44:14] <cradek> that's ok, give it a shot, and if you get stuck, ask another question
[11:44:23] <lair82> I'm not holding you to it, I'm just saying in general, I won't need to go thruogh the crazy stuff on the command line is all.
[11:44:46] <ganzuul> Seems to be highly anti-microbial. Must be since resin is what a damaged tree secrets to heal itself.
[11:44:53] <ganzuul> ~ secretes
[11:45:12] <cradek> you can use synaptic to change 2.6 or 2.7-rtai to 2.7-uspace (depending on which image you started with) and then also use synaptic to install the linuxcnc-uspace package
[11:45:24] <cradek> then reboot
[11:45:42] <cradek> then optionally use synaptic to uninstall the rtai kernel you don't need anymore
[11:45:52] <Loetmichel> ganzuul: i dont think its badly infected. The hole left by the 5mm long broken off sliver after digging it out is black als coal tho ;)
[11:45:53] <cradek> now you're done, you have the right linuxcnc
[11:45:56] <lair82> Ok, sounds fair enough
[11:46:08] <cradek> don't compile anything
[11:46:12] <cradek> copy in your config and run it
[11:46:50] <Jymmm> BACKUP your configs befor eupdating/upgrading =)
[11:47:29] <lair82> Ok, I am going to give it a whirl on the ssd I am putting together to replace the hdd that has been giving me fits.
[11:47:47] <cradek> yay
[11:51:02] <ganzuul> Loetmichel: Everything you could possibly want to know about it, just in case: http://www.repolar.com/media/pdf/Vaeitoeskirja.pdf
[11:55:52] <ssi> _methods: it's got sciency words in the marketing literature, like "HEARING NERVE"
[11:58:41] <Jymmm> I got some sciency words for ya... Dihydrogen Monoxide, sodium chloride,
[11:59:43] <ssi> sounds like a horribly corrosive solvent
[11:59:57] <Loetmichel> in combination it is ;)
[12:00:13] <Jymmm> but great with tequilia or in margaritas!
[12:00:49] <Loetmichel> Jymm: need some citric acid with that then ;)
[12:01:09] <Jymmm> Loetmichel: I prefer fresh lime juice
[12:01:10] <ssi> citric acid, ethanol
[12:02:05] <Loetmichel> ganzuul: i have tons of 99,9% 2-propanol at the company. the laceration got desinfected very throughly ;)
[12:02:33] <ganzuul> That's IPA?
[12:02:48] <ssi> yep
[12:03:07] <Jymmm> 110v 1HP dust collector, hmmm
[12:03:14] <ganzuul> Love the smell; but only when I'm not on the business end.
[12:03:41] <Loetmichel> ganzuul: yes
[12:03:57] <Loetmichel> why?
[12:04:05] <Loetmichel> it burns a bit, but nothiung serious.
[12:04:20] <ganzuul> Being on the business end usually means someone's sticking needles in me.
[12:04:25] <ssi> lol
[12:04:26] <Loetmichel> and it DOES kill any bacteria in the wound
[12:05:04] <ganzuul> Pretty sure my reaction to the smell is hard-wired from childhood trauma.
[12:05:20] <Loetmichel> i dont like needles stuck into me as well
[12:05:27] <Loetmichel> because childhood trauma
[12:05:34] <pcw_home> also not as drinkable as India Pale Ale
[12:05:40] <ssi> pcw_home: that's debatable ;)
[12:05:47] <ganzuul> lol, true
[12:05:57] <Loetmichel> some /%/%& doc got the immunisation syringe in too deep and bent the needle on my bone
[12:06:02] <Loetmichel> ... at age 4 or so
[12:06:30] <ganzuul> I haven't tried it myself, because it just seems strong as fuck, but reportedly it gets you really drunk, really quick.
[12:06:44] <ssi> what, isopropyl?
[12:06:51] <Loetmichel> when i go donating blood every so often i am pale as the bedsheets i am laying on ;)
[12:06:53] <ganzuul> yeah
[12:06:56] <ssi> I think drinking isopropyl is probably a good way to hurt yourself
[12:07:15] <ssi> "The lethal dose of isopropyl alcohol by mouth in adult humans is about 8 ounces."
[12:07:17] <ganzuul> me too, but someone lived to tell the tale at least
[12:07:25] <Loetmichel> ssi: Iopropyl alcohol will get you killed fast
[12:07:50] <ssi> my statement was less about the drinkability of isopropyl, and more about the lack of drinkability of india pale ales :D
[12:07:56] <ganzuul> oic
[12:08:05] <Loetmichel> but it does get you quite wasted if you use it as a cooling agent while milling aluminium ;)
[12:08:16] <ganzuul> hehe
[12:08:26] <Loetmichel> BTDT ;)
[12:08:38] <Loetmichel> ... in a not so well ventilated areay
[12:08:40] <Loetmichel> -y
[12:23:43] <ssi> http://www.theinquirer.net/inquirer/news/2425381/microsoft-is-downloading-windows-10-to-your-machine-just-in-case
[12:23:46] <ssi> lololol
[12:25:28] <ganzuul> That seems unreal.
[12:38:11] <SEL> I am trying spindle control, started with this http://linuxcnc.org/docs/html/examples/spindle.html#_0_10v_spindle_speed but it is unclear to me what is my DAC pin name
[12:39:33] <enleth> Hi there. Just dropping in to get to know you guys, I'll be retrofitting a Bridgeport Series 1 MDI with LinuxCNC controls soon-ish and quite likely hanging out here quite a lot.
[12:48:05] <_methods> welcome to the looney bin
[12:49:44] <enleth> In case anyone is interested, here's a video of the first run after overhaul, cleaning and reassembly, still with the original Heidenhain TNC 131 control and some highly temporary wiring: https://hackerspace.pl/~enleth/20150830_212720.mp4
[12:50:45] <enleth> I nad to disassemble the bugger down to bare iron to make it fit through the door.
[12:52:17] <enleth> Keeping the DC servos, relay-based handwheel logic and varidrive CVT pneumatics. It's going to be a fun project.
[12:52:24] <FinboySlick> enleth: Your ways look rather shiny. Were they re-done?
[12:52:53] <SEL> what is a valid pin name ?
[12:53:05] <FinboySlick> SEL: dowel
[12:53:42] <enleth> FinboySlick: nope.
[12:54:18] <enleth> FinboySlick: they were factory chromed. Some of that is worn off.
[12:54:27] <FinboySlick> I'd really like to have the time and space to work on a moderately big iron conversion some day.
[12:54:39] <Wolf_> looked hand scraped
[12:54:54] <Wolf_> I would hope they haven’t been chromed...
[12:55:04] <SEL> shows an error: basically float do not fit into bit
[12:55:51] <PCW> your spindle DAC pin name depends on what hardware you have
[12:55:56] <enleth> Wolf_: scraped AND chromed.
[12:56:36] <SEL> it is a parallel port controller board
[12:57:17] <enleth> Wolf_: all 80s CNC Bridgeports had such a treatment.
[13:01:34] <PCW> if the spindle is controlled by an analog voltage
[13:01:35] <PCW> (and your parallel port break out card has a analog spindle output )
[13:01:37] <PCW> its likely your DAC pin will be a PWM module value pin
[13:03:38] <SEL> it is in the VFD manual, 0-10 volt input
[13:06:00] <SEL> i mean the inverter takes a 0-10 volt input
[13:12:02] <robinsz> I have to figure out how to pause this router ...
[13:12:51] <_methods> p
[13:15:42] <PCW> Right, thats the VFD input, but how that connects to linuxcnc and HAL depends on your interface hardware
[13:17:45] <PCW> That is, if you want to use 0..10V control you need some hardware between your parallel port and the 0..10V VFD input
[13:22:52] <SEL> looking at the manual it should be some adcout , I will measure output with a voltmeter, btw the board has a spindle interface that should connect to the inverter
[13:23:13] <enleth> Wolf_: the chrome is gone in places but other than that it's in a remarkably good condition, as far as the ways go. It's actually surprising - the paint job is very badly worn or gone in many places, this machine saw a lot of work, but scraping survived on all way surfaces.
[13:23:32] <Wolf_> cool
[13:24:01] <enleth> Even gibs are still OK and factory scraping is visible.
[13:26:11] <enleth> AFAIK it was a tool room machine for spare part production in a furniture factory, so it may have seen very little repeatable workload. That could explain even way wear.
[13:27:46] <enleth> But oh boy, it was *extremely* dirty. A whole bucket of chip gunk came off and out of it.
[13:35:33] <SEL> is it parport.0.adcout.0. <name> ?
[13:40:35] <PCW> No, you need to find out what signal your parallel port breakout requires to generate
[13:40:36] <PCW> the 0..10V and then add the proper HAL component to generate that signal
[13:40:38] <PCW> (most likely the PWMGen if the but sometimes the Stepgen )
[13:41:03] <PCW> - if the
[13:43:45] <magnifikus> any suggestion for a stepper driver? tried hy-dv268n was total shit, 2 died after 3 days
[13:43:59] <magnifikus> thinking about a pcb with trinamics
[13:44:32] <SEL> and where do I find it ?
[13:44:36] <magnifikus> want to driver 2-3amps
[13:45:24] <CaptHindsight> enleth: I have one from 1960 that looks like the ways were all polished :p
[13:45:33] <Wolf_> what voltage level magnifikus
[13:45:44] <magnifikus> i used 48v
[13:45:49] <magnifikus> but can easily go down to 24v
[13:46:58] <Wolf_> I’m using long motors DM542A drivers
[13:47:23] <Wolf_> but any 542 based should work good
[13:48:19] <magnifikus> so not total crap?
[13:48:34] <Wolf_> http://www.aliexpress.com/item/Free-Shipping-Stepper-motor-drivers-M542H-dc18-80v-1-5-4-5A-for-86-motor-stepping/32367292136.html
[13:50:26] <CaptHindsight> archivist: I noticed that this replaced your model CMM. Any idea what these cost new? http://www.hexagonmetrology.us/products/cmms-shop-floor/brown-sharpe-4-5-4sf
[13:51:29] <magnifikus> still dont get why they died
[13:51:43] <magnifikus> was using them at 1.8 amps, and 2 shorted the 48V rail suddenly
[13:52:00] <magnifikus> checken, both vcc pins of the chip are shorted to gnd
[13:53:28] <rob_h> when we was looking at CMMs, depends what you want from it depends on cost, but a manual you could get a deal on at time was 10k - 13k , and CNC was 16k+ thats for a basic machine then any goodies are extra and basic 3D measuring, not surfacing ,
[13:55:02] <Wolf_> I think the div268n/tb6600 drivers are known to be junk
[13:55:30] <CaptHindsight> rob_h: sounds like a good racket to get into unless it's a patent minefield
[13:55:38] <rob_h> but we have a Trimos vertical, which we measure with daily and is way more acerate than any CMM by amile
[13:57:12] <rob_h> its all granite so no idea what that costs , and all the renishaw probe stuff but i bet they pay very little for it all. seems there is a margin on them yes as you can get quotes down alot when you start getting more than two companys involved
[13:58:00] <Sync> no shit
[13:59:16] <Sync> overvoltage on decel magnifikus?
[13:59:48] <magnifikus> sync was standing still since 20 minutes
[14:00:05] <Sync> hmm
[14:00:17] <magnifikus> we even mounted the chips directly on a large heatsink
[14:00:22] <Sync> overvoltage damage is slow usually
[14:00:25] <magnifikus> to get rid of the crappy case
[14:00:39] <enleth> CaptHindsight: manual V-ram?
[14:00:40] <magnifikus> hmm was a good meanwell
[14:01:14] <CaptHindsight> ever notice when you do "Ask an Expert!
[14:01:14] <CaptHindsight> Not sure which one is right for you? Ask us, we can help you figure out exactly what you need." it tends to be the most expensive option
[14:02:02] <Wolf_> them div268 are rated at 12-48v dc from the china specs, so I read that as safe up to 36v :P
[14:02:11] <magnifikus> hehe
[14:06:00] <Sync> well only because the power supply is good the voltage on the driver itself must not be within spec
[14:06:54] <Wolf_> voltage can jump up on decel too (I think)
[14:07:58] <SEL> trying with pwmgen
[14:16:45] <kengu> yeah.. emi travels to stepper somehow on laser startup. when ever laser is fired there is emi visible on camera and also stepping on stepper
[14:20:55] <CaptHindsight> kengu: just about every machine I've ever owned had wiring issues or poor electrical component locations when it arrived
[14:21:59] <CaptHindsight> control cabinets tend to be laid out aesthetically vs for best performance
[14:22:47] <kengu> CaptHindsight: can be pretty much everything. the thing is it worked for some days and then someone slammed the lid and after that then the emi started. all wiring seems to be at its places
[14:24:11] <CaptHindsight> I thought that giving it a hit generally fixes things :)
[14:26:06] <_methods> that's what i thought too, then i got married
[14:29:09] <kengu> is there a guide on proper laser wiring somewhere?-)
[14:31:46] <kengu> should be straight lines.. https://www.dropbox.com/s/oc64an0zhqb761l/20150910_003.jpg?dl=0
[14:32:09] <kengu> jogging only on one axis but the other is stepping also
[14:32:46] <_methods> so many lasers
[14:37:16] <CaptHindsight> kengu: does they move at the same rate?
[14:37:57] <CaptHindsight> looks like NO from the pic
[14:38:19] <kengu> not the same rate.. not taking all the same steps
[14:38:39] <CaptHindsight> kengu: does it only happen when the laser is ON?
[14:39:04] <kengu> only when laser is on and the extra steps in the pic are cause of pwm drive of laser
[14:39:17] <kengu> as with simple "laser on" it only jumps at the start
[14:39:42] <kengu> so random jump when ever laser is fired and with pwm it is fired all the time
[14:40:53] <CaptHindsight> take a look at the power and grounds, probably lots of noise on them, but WHY will take some investigation
[14:41:23] <CaptHindsight> what go either knocked loose or broken from the SLAM
[14:41:31] <CaptHindsight> go/got
[14:45:47] <kengu> lots of noise.. yes. and the investigation has been going on for weeks actually.. on and off
[14:52:42] <Sync> put a few ferrites around the laser cable
[15:00:20] <CaptHindsight> kengu: are you certain it's EMI and not a power supply problem?
[15:00:51] <kengu> we have a replacement HV power suply
[15:01:15] <kengu> and tried with that and also the other power supply has been replaced
[15:02:24] <kengu> Sync: hum.. one ferrite around did make the interference go away from the camera.. still on the stepping .. but we'll call this a day and continue later.
[15:18:57] <HSM> Good evening guys
[15:21:39] <HSM> Has someone with little atlas copco air compressors?
[15:22:00] <HSM> *experiences
[15:22:09] <JT-Shop> heard of em
[15:23:42] <HSM> Im interested in automan AF 20 e 10 http://www.atlascopco.si/images/2935%200881%2045_automan_tcm795-1626668.pdf
[15:25:16] <HSM> But I think there is a chance that atlas build this thing in low coast quality and sell it for big money because of the name...
[15:32:57] <HSM> On 19.9 -20.9 some cool guys make a linuxcnc meeting in stuttgart germany
[15:33:22] <HSM> https://piratenpad.de/p/linuxcnc
[15:35:43] <CaptHindsight> HSM: "Christian Stöveken - 6 axis Robot conversion" did he already complete this?
[15:37:54] <HSM> you mean this: https://www.youtube.com/watch?v=ZBIX_MliFeU?
[15:39:52] <HSM> I didn´t heard some news
[15:45:38] <JT-Shop> anyone using inkscape to generate G code? A fellow on the forum is having issues with arcs
[15:49:12] <cradek> wonder how far off it is. would be nice if he had given an example.
[15:49:28] <cradek> he just says "yep I agree it's wrong"
[15:50:10] <cradek> it might be a precision problem, or it might be sane but wrong (incorrect center mode assumed, or similar), or it might just be insane (totally broken)
[15:52:16] <HSM> b
[16:04:15] <JT-Shop> I asked him about precision and he said he had it set at 4
[16:05:39] <cradek> I don't know why he isn't working on inkscape if the gcode it generates is verifiably wrong
[16:07:57] <JT-Shop> another weird email from Mr. Dark... that guy is strange
[16:08:09] <renesis> so youre saying i should keep using fusion360
[16:08:24] <renesis> jt-shop: guys name is mr dark
[16:09:23] <JT-Shop> I think fusion 256 is better
[16:09:55] <renesis> is it 2.5d like mode7 on super nintendo?
[16:10:01] <JT-Shop> *JT-Shop* goes to rummage through his buddys shop for some clamps
[16:21:41] <MacGalempsy> http://www.pastebin.com/bTPXXM0f
[16:22:08] <MacGalempsy> If someone could take a look at that and tell me why my z axis fails when it hits the endstop, I would appreciate it
[16:23:39] <_methods> wouldn't 1 put it past your stop if its at 0?
[16:24:15] <cradek> what do you mean fails when it hits the endstop?
[16:24:58] <cradek> (negative FF1 is very surprising)
[16:25:01] <MacGalempsy> the axis moves towards the home position and the first time it hits the endstop, the machine shuts downs and an error is produces that states joint 2 following error
[16:25:29] <MacGalempsy> i guess ignore the tuning
[16:29:38] <cradek> why is it hitting the endstop? a ferror is normal if you crash into something
[16:30:05] <cradek> does it go past the home switch? I don't understand what your situation is yet
[16:31:01] <_methods> his home is at -0.1 and the max limit is 1.00
[16:31:13] <_methods> not sure if that is affecting it
[16:33:09] <CaptHindsight> MacGalempsy: are you expecting that when you hit the enstop that the axis will then reverse direction and search for home?
[16:33:22] <CaptHindsight> enstop/endstop
[16:36:53] <andypugh> My cheap servo (I think I paid £30) has a couple of large ball-latch connectors, which I have never managed to find.
[16:37:43] <andypugh> I don’t know why I didn’t think of this before, but it is easy to just take the connectors off and fit some receptacles that I _do_ have conectors for. Like a Speakon for the motor and a Lemo for the resolver.
[16:38:10] <cradek> connectors are the worst things
[16:38:32] <andypugh> On the Mill I paid £50 for three servos, then £70 _per_motor_ for connectors.
[16:38:46] <cradek> still sounds like a deal
[16:39:40] <andypugh> Yeah, nice motors. But they turned me into a Resolver enthusiast. This evening I have mainly been fitting a resolver to a motor that used to have an encoder. I doubt many people make that swap
[16:40:32] <cradek> resolvers are superior in every way except price, so if you've found a workaround for that, awesome
[16:40:47] <andypugh> I now have two motors that will fit the lathe, they both have resolvers. This is looking like another 7i49 / 8i20 project
[16:40:55] <cradek> my mill's rotary table has a resolver, and I don't remember if I did that or if it came that way
[16:41:01] <cradek> I think I put it on there
[16:41:55] <andypugh> I have one 8i20 available (Serial number 3 :-)
[16:43:48] <andypugh> I could show-off my “collectible” low serial 8i20 by using the Hsotmotw “use_serial_numbers” option. I ought to anyway, it gives smart-serial devices pins named after their serial number rather than what and where they are connected to.
[16:44:11] <andypugh> (Err, Hostmot2, not Hsotmotw)
[16:45:33] <andypugh> So, instead of hm2_5i23.0.8i20.0.1.current it would be hm2_8i20.0003.current
[16:45:56] <cradek> that seems useful
[16:46:30] <andypugh> Especially as it means you don’t have to remember where each RJ45 cable came from when re-connecting
[16:46:38] <cradek> I have two 5i20s in jr, and I think they're enumerated by PCI slot or somesuch
[16:46:59] <andypugh> the feature has been there for years, I only remembered to document it a couple of months ago
[16:47:00] <cradek> they never switch around on their own, but figuring it out at first is tricky
[16:47:39] <andypugh> Unfortunately this feature is smart-serial only. I think the 5i20 is too dumb to know its own name.
[16:49:33] <cradek> aw
[16:50:02] <ssi> http://❤️✈️.ws
[16:50:04] <ssi> does that work? :P
[16:50:25] <andypugh> Yup
[16:50:28] <ssi> :D
[16:50:55] <andypugh> (Safari on a Mac.)
[16:51:23] <ssi> yea I knew it worked in safari :P
[16:51:26] <ssi> I think it won't work in chrome
[16:51:42] <ssi> too much money to spend on a silly proof of concept but whatever

[17:02:08] <ssi> dammit jt i'm so hungry and you do THAT to me?!
[17:02:43] <Jymmm> JT-Shop: You forgot the marinated cucmber salad
[17:04:22] <Jymmm> JT-Shop: This is REALLY GOOD SHIT... http://www.amazon.com/Taste-Thai-Peanut-Sauce-24-Ounce/dp/B000E7WM1E

[17:05:24] <Jymmm> You can find packets on the grocery store if you dont want that big of a container, but it last in the frig a long time, as you add/mix your own coconut milk when you are making a batch of it.
[17:06:02] <Jymmm> I usually mix a small can of coconut milk worth at a time.
[17:06:18] <andypugh> You know, it’s hard to beat Speakon for motor connectors. 40A rated, 4 poles, waterproof, £5 each. http://www.maplin.co.uk/p/neutrik-nlt4mp-4-pole-male-chassis-speakon-connector-n50gb
[17:06:57] <HSM> you can mill your own cake out of black chocolate
[17:07:19] <Jymmm> renesis: screw the noodles
[17:07:32] <renesis> screw you noodles are life!
[17:07:34] <Jymmm> renesis: That jsut fucks up the chicken satay
[17:07:40] <HSM> just use endmill with one edge
[17:07:53] <Jymmm> renesis: You want noodle? Eat ramen bitch!
[17:08:05] <renesis> i ramens are not as good
[17:08:25] <renesis> chicken satay is an appetizer
[17:08:37] <Jymmm> renesis: It's like going out to a restreaunt to eat spaghetti, That's just SO wrong
[17:08:50] <Jymmm> renesis: Not the way I serve it =)
[17:08:55] <HSM> :)
[17:09:08] <renesis> why the noodles have seared beef
[17:09:23] <Jymmm> So eat served beef instead
[17:09:27] <renesis> i usually do pad se ew and the coconut mushroom soup
[17:09:32] <Jymmm> seared*
[17:09:47] <renesis> the almost green curry stuff
[17:10:03] <Jymmm> too many starched fuck up such a rich meal
[17:10:28] <renesis> next youre going to say too much bread is actually a thing
[17:10:29] <Jymmm> the cucumber salad compliments the richness of the peanute sauce
[17:10:43] <Jymmm> renesis: too much bread???
[17:11:03] <Jymmm> renesis: rephase what you said, I didn't understand
[17:11:22] <renesis> noodles are good
[17:11:31] <renesis> shish ka bob is nice
[17:11:40] <Jymmm> starches are fillers
[17:11:47] <renesis> with the peanut sauce, honestly i dont even open the little cucumber salad container
[17:11:48] <Jymmm> kabobs are great
[17:12:05] <Jymmm> container?! WTF
[17:12:29] <renesis> also the hawaiian curry fried rice with the pineapples and cashews
[17:12:30] <Jymmm> this aint out of a bag/continer ya buum!
[17:12:45] <renesis> and chicken and shrimps (i give the shrimps away)
[17:12:52] <Jymmm> except the peanut auce, cause I got thur too much of it =)
[17:12:52] <renesis> i <3 that shit
[17:13:04] <Jymmm> go through*
[17:13:14] <renesis> and sure its out the bag/container
[17:13:24] <Jymmm> renesis: you sick puppy!
[17:13:25] <renesis> badass thai food all over where i used to live
[17:13:26] <ganzuul> https://www.youtube.com/watch?v=YqSvkNjWnnQ
[17:13:34] <renesis> just a couple places here =(
[17:13:36] <HSM> what was the base question? Noodles or not noodles?
[17:13:46] <Jymmm> renesis: Well, not as good as fresh... just sayin
[17:13:51] <renesis> jymmm: seriously theres badass highend takeout thai food all over LA
[17:13:57] <renesis> how is it not fresh?
[17:14:11] <renesis> they make it you pick it up youre eating it in 10 minutes?
[17:14:15] <Jymmm> renesis: There are homeless all over LA too...
[17:14:26] <renesis> what does that have to do with thai food
[17:14:35] <renesis> and not all over LA
[17:14:40] <renesis> they are mostly in specific parts
[17:14:57] <PetefromTn_> its so funky
[17:15:09] <Jymmm> renesis: Not a dman thing, same as having hundreds of ethnic places in LA or Misery
[17:15:28] <PetefromTn_> I could imagine someone watching that stoned might be quite an experience
[17:15:59] <Jymmm> renesis: Sadly, where I am now there is only ONE indian place within a 50 mile area, it's okey
[17:16:05] <renesis> anyway, get over chicken satay, its nice but theres lots of other good shit
[17:16:17] <renesis> and takeout is awesome i dont know why youre tripping
[17:16:22] <Jymmm> beef/pork basil
[17:16:38] <Jymmm> renesis: fuck take out over steam in the plastic bag it came in
[17:16:44] <renesis> where i am for school there is like maybe two or three of everything
[17:16:45] <Jymmm> steamed*
[17:16:50] <renesis> and one of them is good
[17:16:57] <renesis> lots of mexican, mostly they suck
[17:17:06] <renesis> thats not true really, its not like LA tho
[17:17:32] <Jymmm> Same here, one is actually more like midwest version of "mexican" food. I almost expect "vegeall" on the plate sadly.
[17:19:20] <HSM> the only mexican food we eat here is "taco"
[17:20:41] <PetefromTn_> we have a decent mexican restaurant local to us... there are several that suck but only one that is good...
[17:20:47] <JT-Shop> looks good Jymmm
[17:20:52] <PetefromTn_> its called panchos
[17:21:15] <PetefromTn_> and they have several relatively authentic mexican plates in addition to the typical fare
[17:25:03] <andypugh> The only Mexican restaurant I go to with any regularity is in Lapland. Which is vaguely ironic.
[17:25:43] <andypugh> I associate Mexican food with it being -30C outside :-)
[17:26:51] <HSM> it´s hot enough for -30C
[17:28:45] <JT-Shop> we have a half dozen mexican places and one is run by real mexicans, they have the best food
[17:28:47] <Deejay> gn8
[17:29:06] <JT-Shop> say goodnight Gracie
[17:30:31] <jdh> goodnight, gracias
[17:30:56] <PetefromTn_> grassy ass
[17:31:11] <roycroft> i bet the margaritas are nice and cold there
[17:33:28] <PetefromTn_> hehe whenever I walk into Pancho's restaurant I always yell out loud to the owner 'HEY MI AMIGO!!" he always laughs and smiles he's a funny guy... You would have to be there to see that this is actually funny I suppose LOL
[17:37:10] <tiwake> just fixed a DRO for the lathe... somebody wasent paying attention to where the cable was wrapped around and pulled the cable in half
[17:37:19] <tiwake> meh
[17:38:00] <HSM> nice
[17:38:47] <HSM> use shower pipe for cable secure
[17:39:03] <HSM> *protection
[17:39:41] <andypugh> I am trying to figure out a good way to get cables to the saddle of my lathe
[17:39:49] <andypugh> The current lathe uses a cable chain.
[17:40:10] <andypugh> But I am wondering if a telescopic spring and spiral cables would be neater
[17:40:34] <andypugh> But I have never seen that done.
[17:40:47] <tiwake> HSM: or maybe hydraulic tube
[17:40:56] <HSM> yes
[17:40:57] <tiwake> the steel braided stuff
[17:41:15] * JT-Shop has to wait for 2.7.1 to come out so he won't have to look at the horrible menu he created
[17:41:55] <PetefromTn_> what menu?
[17:42:08] <andypugh> Oh FFS! I have ruined the internet for myself. Google “CNC lathe saddle wiring” click images. What do I see? My own lathe….
[17:42:09] <HSM> igus has fully closed chains for extreme conditions
[17:42:23] <HSM> ^^
[17:42:52] <PetefromTn_> my CNC lathe has this sorta sealed metal accordion thingy on it
[17:43:45] <HSM> @andypugh: link?
[17:43:48] <PetefromTn_> when I went to visit that shop that wanted me to work there part time they had a nice HAAS TL1 lathe in there. that is a very simple CNC lathe but seeing it up close and in person it is a pretty nice machine
[17:43:49] <andypugh> RS only has super-costly 3D bendy stuff in fully sealed: http://uk.rs-online.com/web/p/cable-trunkings/6188522/
[17:44:08] <tiwake> andypugh: you have desecrated the internet! We need to initiate the cleansing protocol now!
[17:44:14] <fenn> pretty cable chain http://i00.i.aliimg.com/photo/v0/1800503532_3/CW62163C_horizontal_lathe_normal_conventional_gap_bed.jpg
[17:44:36] <PetefromTn_> yup that is what my CNC lathe has...
[17:44:44] <PetefromTn_> sorta accordion bendy looking steel stuff
[17:44:45] <andypugh> If I google “Holbrook Minor” I end up with loads of images of Ner-a-Car parts, and almost none of any Holbrook Minor lathes.
[17:44:46] <HSM> yes this 3d bendy is from igus
[17:45:32] <HSM> i hate steel stuff cable chains
[17:45:33] <andypugh> I specifically don’t want 3D bendy. If it’s cable chain it has to the the “sits straight” type.
[17:45:42] <PetefromTn_> after seeing that TL1 lathe I REALLY started to realize that I absolutely MUST get my CNC lathe finished here soon LOL
[17:45:51] <fenn> andypugh: i dont see any motorcycle stuff if i do the same search, must be google feeding you your own dogfood, that's their policy right?
[17:46:42] <andypugh> fenn: interesting, nor do I now.
[17:47:03] <fenn> they're listening...
[17:47:06] <andypugh> The very first image for “Holbrook Minor Lathe” isn’t a Holbrook Minor. (It’s a Major)
[17:48:07] <andypugh> They go Major, Minor, Smart and Brown 1024, Minor, B13, Minor, (mystery)
[17:48:29] <andypugh> (mystery = Reiden)
[17:49:31] <andypugh> Hmm.. http://www.practicalmachinist.com/vb/schaublin-cazeneuve-weiler-graziano-mori-seiki-lathes/high-precision-swiss-lathe-reiden-130636/ Why do people like a left-side handwheel? I prefer _not_ to have the hot swarf fall on my hands.
[17:50:21] <HSM> I don´t now
[17:51:56] <HSM> sometimes because of the feature that you can handle the upper slide and support together
[17:52:19] <HSM> fos some human power working...
[17:53:33] <HSM> My VOEST Lathe also has the handwheel on the left side
[17:53:45] <HSM> but it´s NC
[17:53:47] <JT-Shop> is a cm 10 mm?
[17:53:55] <JT-Shop> or 100?
[17:54:00] <JT-Shop> can't remember
[17:54:15] <HSM> https://www.google.de/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=cm%20in%20mm
[17:55:20] <andypugh> JT 10
[17:55:34] <JT-Shop> thanks
[17:55:58] <andypugh> Just don’t ask me about hectoPascals
[17:56:19] <JT-Shop> lol
[17:56:20] <DaViruz> that's a silly unit
[17:56:31] <HSM> yes
[17:56:43] <DaViruz> hell, any non-1000-prefix is kinda sily
[17:57:48] <SpeedEvil> There are worse things in metrology.
[17:57:55] <SpeedEvil> (than non 1000)
[17:58:11] <SpeedEvil> Perceptual light units come to mind.
[17:58:15] <DaViruz> sure, imperial units ;)
[17:58:20] <SpeedEvil> Lumens, nits, candellas.
[17:58:40] <SpeedEvil> You need to actually take into account the spectrum of the light to properly work out brightness
[17:59:03] <SpeedEvil> Not to mention the nightmare that is colour perception
[17:59:12] <DaViruz> yeah light can be complicated
[17:59:14] <DaViruz> sound as well
[18:01:35] <HSM> sounds like some stoned experiences
[18:02:22] <PetefromTn_> http://www.roadandtrack.com/new-cars/future-cars/news/a26636/for-people-afraid-of-motorcycles-theres-the-honda-24/ pretty sweet!
[18:02:44] <HSM> yes looks like KTM x bow
[18:03:23] <HSM> but their is no armrest for cool guys...
[18:03:24] <PetefromTn_> Looks a helluva lot better if you ask me
[18:04:07] <HSM> and side impact safety is shit
[18:04:45] <DaViruz> whats with the offset seat
[18:04:48] <DaViruz> that looks silly
[18:05:32] <HSM> No. that looks silly: http://i.huffpost.com/gen/1820256/images/o-DRIVERLESS-CAR-facebook.jpg
[18:05:35] <HSM> :D
[18:06:10] <DaViruz> i can't argue with that :)
[18:11:48] <tiwake> PetefromTn_: looks expensive
[18:13:38] <HSM> Has somebody a tip for a machine with profile linearbearings and ac servomotor for retrofit?
[18:13:40] <andypugh> Sitting next to the engine like that is sort-of like a Kart
[18:13:44] <PetefromTn_> probably
[18:13:53] <HSM> Mazak VM 40 looks good to me
[18:14:50] <HSM> the old portal one
[18:15:11] <andypugh> HSM: That seems an odd set of starting features. “I don’t care abour machining envelope, number of axes or spindle speed, but I do care about the servo type and the slideways” ?
[18:15:15] <PetefromTn_> hitachi
[18:16:48] <HSM> andypugh: yes
[18:17:10] <Tom_itx> PetefromTn_, bless you
[18:17:53] <PetefromTn_> Oh thank you!
[18:18:01] <PetefromTn_> bless you as well
[18:18:16] <Tom_itx> sounded like you were sneezing there...
[18:18:43] <PetefromTn_> yeah I got it
[18:18:50] <HSM> i get some offers for chiron fz08 which is okay for all products. But i think that a older machine (whatever) with the newest controlls and linuxcnc could be the better way
[18:19:13] <PetefromTn_> I like the chiron machines they are a cool design
[18:19:22] <HSM> yes
[18:19:42] <Tom_itx> i wish software worked like i thought it should instead of how it does
[18:20:09] <HSM> :)
[18:20:16] <CaptHindsight> Tom_itx: x2
[18:22:22] <HSM> at the moment we have a dmc 1035 and flexicam stealth (with pour control)
[18:23:16] <PetefromTn_> NICE MORI
[18:23:26] <HSM> yes but to slow
[18:24:00] <HSM> and bad spindle (8k)
[18:24:38] <PetefromTn_> jeez you would probably HATE my machine LOL
[18:25:13] <CaptHindsight> yeah, anything under 10k rpm is for old people :)
[18:25:24] <HSM> finally i don´t know what i want. But i want a better machine...
[18:25:25] <Tom_itx> or steel hogouts
[18:25:54] <andypugh> My mil spindle peaks at 1000 rpm….
[18:25:54] <Tom_itx> HSD, look at okuma
[18:25:57] <CaptHindsight> add a new spindle
[18:26:05] <HSM> and i need some cnc playground
[18:26:17] <HSM> okuma, which one?
[18:26:25] <Tom_itx> take your pick
[18:26:29] <andypugh> I spend a lot of time thinking of ways to make a faster spindle :-)
[18:27:14] <CaptHindsight> http://www.pdsspindles.com/automatic-tool-change/dynaloc-series if you're lazy
[18:28:02] <andypugh> On the plus side, I have unstoppable torque at < 1rpm, which is no good for milling, but can be handy for some other jobs: https://www.youtube.com/watch?v=thtDRjgbxRE
[18:28:48] <CaptHindsight> andypugh: about an hour from me http://www.milwaukeegear.com/custom-gears/double-helical-gears.html
[18:28:55] <HSM> spring winding is for lathes
[18:29:47] <andypugh> The company my dad used to work for made triple helical gears for a while. That’s actually a really stupid idea.
[18:30:06] <HSM> :D
[18:30:21] <CaptHindsight> https://www.youtube.com/watch?t=1&v=3tZCsmRdWzQ HOBBER WITH DOUBLE HELICAL PINION
[18:34:28] <andypugh> The Internet seems to have no pictures of a Triple Helical gear, but I have seen one at David Brown. My dad ans I discussed at the time what a stupid idea it was.
[18:35:11] <HSM> good feature for stupid customers
[18:36:13] <SpeedEvil> Triple helical gear sounds like something you specify when your device is not expensive enough
[18:38:51] <HSM> ...perfectly for research and technology
[18:39:43] <HSM> or crazy funding programmes ^^
[18:42:47] <andypugh> But triple helical is much, much _worse_ than double helical.
[18:43:51] <CaptHindsight> https://youtu.be/x8SXT9iMY1U?t=43s me want 5-Axis Bevel Gear Cutting Machine
[18:45:51] <HSM> gn8
[18:46:00] <andypugh> I need to learn how to make bevels.
[18:51:29] <andypugh> CaptHindsight: I just realised, a bevel like that has flat tooth flanks.
[18:53:42] <zeeshan> bevel gears are cool
[18:56:49] <CaptHindsight> https://youtu.be/gj2szHk0OCU?t=1m45s HYPOID GEAR CUTTING SPIRAL BEVEL
[18:57:22] <PetefromTn_> zeeshan do you have a working Ebrake on your RX7?
[18:57:56] <zeeshan> yes pete
[18:58:34] <zeeshan> dude the anticipation for tommorrow is killing me
[18:59:22] <PetefromTn_> I know right
[18:59:28] <PetefromTn_> they have this car at work
[18:59:56] <PetefromTn_> it is the really built custom red one
[19:00:01] <andypugh> OK, time to log off. Night all.
[19:00:05] <PetefromTn_> and it has the fender flares
[19:00:21] <PetefromTn_> those neat bolt on ones
[19:00:34] <PetefromTn_> so they are able to put a HUGE rear wheel/tire combo on it
[19:00:40] <zeeshan> nice
[19:00:51] <PetefromTn_> it has massive disk brakes and six piston calipers
[19:01:04] <PetefromTn_> but it as yet does NOT have an emergency brake
[19:01:10] <zeeshan> hehe
[19:01:26] <PetefromTn_> they bought a pair of those wilwood Ebrake calipers
[19:01:40] <PetefromTn_> and today my job was to fab up SOME way to install the damn things
[19:01:52] <PetefromTn_> without cutting or welding on the stock suspension setup
[19:02:05] <PetefromTn_> what a pain in the ass LOL
[19:02:17] <zeeshan> i think usually people make a custom bracket
[19:02:21] <zeeshan> from the 2 bolt holes for the caliper
[19:03:06] <PetefromTn_> well this car already has the big brakes using the existing holes for the original caliper
[19:03:13] <PetefromTn_> so this must go SOMEWHERE else
[19:03:18] <zeeshan> ah
[19:03:54] <PetefromTn_> the only place it can do is actually between the lower control arm mount and the forward suspension mount that goes towards the front of the car
[19:04:37] <PetefromTn_> so I stared making some bracketry that will allow that.
[19:04:44] <zeeshan> nice
[19:04:52] <zeeshan> keep the design
[19:04:54] <PetefromTn_> it is ONLY for this car since no other car will probably have this sort of setup
[19:04:56] <zeeshan> you could prolly sell it
[19:05:00] <zeeshan> on rx7club
[19:05:02] <zeeshan> youd be suprised
[19:05:12] <PetefromTn_> I dunno I doubt it...
[19:05:28] <PetefromTn_> this car even has wheel spacers on it to mount the HUGE wheels...
[19:05:50] <PetefromTn_> Ya know something I found interesting
[19:05:58] <PetefromTn_> when we worked on it today
[19:06:08] <PetefromTn_> all the lifts had cars on them
[19:06:56] <PetefromTn_> so we just jacked up the RX7 on the floor
[19:07:09] <PetefromTn_> I was kinda surprised at just how RIGID that car is
[19:07:19] <PetefromTn_> we jacked up the car near the back under the door
[19:07:30] <PetefromTn_> and the whole side of the car came up off the ground
[19:07:31] <zeeshan> and the whole left side
[19:07:32] <zeeshan> comes off
[19:07:33] <zeeshan> haha
[19:07:33] <zeeshan> ytea
[19:07:41] <PetefromTn_> I did not expect that
[19:07:56] <PetefromTn_> AND It did not seem to flex whatsoever like a lot of import cars do
[19:08:06] <zeeshan> its really a timeless car
[19:08:12] <zeeshan> they have gone up in value over the years
[19:08:23] <zeeshan> a v8 converted rx7 goes for 30k usd
[19:08:29] <PetefromTn_> I have had a bunch of similar cars
[19:08:34] <zeeshan> which is a lot for an import
[19:08:39] <PetefromTn_> never seen that when jacking them up before
[19:08:54] <zeeshan> my subie does the same thing
[19:08:55] <PetefromTn_> they got a pretty cool car in for a tune today tho
[19:08:55] * ganzuul investigates drawbar technology...
[19:08:57] <zeeshan> the eclipse doesnt
[19:09:19] <PetefromTn_> they have a lexus SC300 that has been turned into a full blown drift car

[19:09:56] <PetefromTn_> big fat wheels
[19:10:06] <PetefromTn_> HUGE massive cartoony wing on the back LOL
[19:10:14] <zeeshan> lol
[19:10:18] <zeeshan> typical drifters!!!
[19:10:18] <zeeshan> :D
[19:10:21] <zeeshan> okay i need to go work
[19:10:32] <PetefromTn_> get to work you lazy ass
[19:10:33] <zeeshan> i gotta get this job done before tomo morning before work
[19:10:35] <zeeshan> :P
[19:10:47] <PetefromTn_> ;)
[19:10:55] <ganzuul> ~.o!
[19:11:36] <ganzuul> woah
[19:11:50] <ganzuul> I'm looking into something like this, man; http://www.toolsandmods.com/lathe/lathe-drawbars
[19:12:21] <PetefromTn_> for what?
[19:13:50] <ganzuul> I ordered the Super C3 lathe today!
[19:14:05] <PetefromTn_> super c3?
[19:14:23] <ganzuul> 7x16, 500W BLDC
[19:14:53] <ganzuul> Looks like my first project will be a drawbar.
[19:15:06] <PetefromTn_> okay the mini lathe super c3
[19:15:19] <PetefromTn_> is the drawbar for a collet closer or something?
[19:15:33] <ganzuul> MT3 morse taper
[19:15:44] <ganzuul> Through the spindle.
[19:16:10] <PetefromTn_> what do you plan to use in MT3 that will go in the spindle?
[19:16:24] <ganzuul> An end mill holder.
[19:16:54] <PetefromTn_> huh
[19:17:18] <PetefromTn_> I saw someone install an ER32 collet holder on one recently I can certainly see some good uses for that on a mini lathe
[19:17:53] <ganzuul> Yeah, I wanted the ER32 collet chuck, but took the vertical milling attachement instead.
[19:19:33] <ganzuul> Will have to get more stuff later.
[19:20:12] * Tom_itx can't tell if zeeshan is working or working anymore
[19:28:34] <fenn> ganzuul: should have gotten the 4-jaw instead of milling attachment, imho
[19:28:46] <fenn> you can do a lot of tasks on a lathe with just a 4 jaw
[19:29:01] <fenn> can't do very much with a milling attachment though
[19:29:12] <ganzuul> hmm
[19:30:18] <fenn> try to find a scrapyard you can dig around in for stock
[19:30:36] <ganzuul> Yeah, I've fond one. :)
[19:30:57] <ganzuul> Gonna look for job shops too which might have offcuts.
[19:31:13] <fenn> learn how to use a face plate and angle blocks
[19:31:43] <ganzuul> There's so many things I still need...
[19:31:48] <fenn> though i wonder if your machine can go slowly enough
[19:32:29] <fenn> brushless means variable speed right?
[19:32:32] <ganzuul> I plan on modifying it a lot.
[19:32:42] <ganzuul> Yeah. Reverses direction too.
[19:32:49] <fenn> or is it just variable torque?
[19:33:02] <ganzuul> So for threading I can back up and go again without disengaging the locknut.
[19:33:05] <PetefromTn_> I am gonna need to find a decent Bison Set tru 3 jaw chuck with D1-5 camlock back here somewhere for a good price LOL
[19:33:10] <ganzuul> Variable speed.
[19:33:42] <ganzuul> Torque should be constant.
[19:33:47] <fenn> you want to back out of the cut anyway because the cutter will rub on the return
[19:33:56] <fenn> while threading
[19:34:18] <ganzuul> Oh yeah absolutely. Backlash is going to mess up the thread otherwise... I think.
[19:35:29] <fenn> this is the obligatory "intro to lathe work" demo piece http://homepage3.nifty.com/amigos/screw_jack/screw_jack-e.htm
[19:35:45] <PetefromTn_> anyone ever heard of Gator lathe chucks?
[19:36:31] <ganzuul> Nifty. :)
[19:37:21] <Jymmm> PetefromTn_: Well, JT-Shop has gators, and a lathe, and probably knows someone named Chuck, so I think he's the expert here.
[19:37:29] <ganzuul> Make the center body out of hex stock, maybe, and a reverse helicity screw on the other side. Got yourself a jack.
[19:38:07] <PetefromTn_> he has Gator chucks?
[19:42:35] <PetefromTn_> That HAAS lathe had a nice bison set tru 3 jaw on it.. looked really nice
[19:42:47] <PetefromTn_> I am gonna try to swing one of those once it is operational
[19:45:19] <ganzuul> Could maybe index with an offest disk and a really accurate dial gague.
[19:46:13] <ganzuul> So the disk works as a cam and you convert your reading off the dial to angle.
[19:48:52] <ganzuul> And measure ID by putting a ball bearing over the hole and measuring how much lower it went, compared to its diameter
[19:49:20] <ganzuul> A bit of trig would get you the ID.
[19:49:21] <fenn> usually that's done with a linear taper
[19:49:37] <fenn> a shallower taper is more accurate
[19:50:13] <fenn> i like a split ball for measuring bores
[19:50:51] <ganzuul> Seen those. Seems a litte fiddly compared to a taper.
[19:51:54] <fenn> not as fiddly as "telescoping" bore gauge
[19:52:18] <ganzuul> Why are those so popular? I can't think of a worse way to measure an ID.
[20:04:04] <_methods> if you know how to use them they work just fine
[20:09:16] <ganzuul> Mmh... Suppose one easily could introduce an error with the math I suggested too.
[20:10:49] <fenn> gah lindsay books shut down
[20:11:02] <fenn> now where am i supposed to get 1900s books about mechanical measuring apparatus :(
[20:15:51] <ganzuul> Coming from a digital background, I thuroughly enjoy all this analog stuff. Very refreshing.
[20:15:52] <roycroft> i got an 11th ed machinery's handbook for $0.75 at a used book store today
[20:15:57] <ganzuul> But now, sleep.
[20:16:24] <fenn> you can do a lot of this with a CMM, if you have a CMM...
[20:16:37] <roycroft> i should probably flip it for $15
[20:17:02] <roycroft> but i do have a new to me kennnedy upper in my welding shop now, and the machinery's handbook drawer in that is empty
[20:17:05] <roycroft> so it may go out there
[20:17:19] <fenn> they were made for each other
[20:17:40] <roycroft> this one has the thumb tabs
[20:17:50] <roycroft> i don't think my 12th ed copy has thumb tabs
[20:18:36] <roycroft> i really don't need another copy, but i was incapable of not buying it at that price
[20:19:07] <fenn> i wouldn't mind a paper edition
[20:19:42] <roycroft> you have to have something to put in that drawer
[20:19:57] <roycroft> better a machinery's handbook than a tiny bong
[20:20:08] <_methods> lol
[20:20:11] <fenn> stacks and stacks of hundred dollar bills
[20:20:16] <_methods> bottle of mad dog and a bong
[20:29:12] <fenn> hehe is this you com/itm/MACHINERYS-HANDBOOK-11th-EDITION-Printed-in-1942-/252087257421
[21:09:26] <roycroft> i'm not flipping it yet
[21:10:06] <roycroft> and my copy is in much better shape
[22:31:54] <skunksleep> http://www.machsupport.com/forum/index.php/topic,30850.0.html
[22:37:34] <malcom2073> "We have features you didn't even know exited (and didn't know you wanted!)
[22:38:00] <malcom2073> existed*
[22:39:07] <Tom_itx> and maybe a few you didn't want?
[22:41:15] <furrywolf> http://lostcoastoutpost.com/2015/sep/10/stolen-u-haul-recovered-sex-toys-jewelry-and-syrin/ wtflol
[22:53:47] <furrywolf> there's too many unanswered questions. for example, that quantity of drugs and sex toys is very expensive. good silicone toys are $50-$150. So... they had a lot of spare money, and decided to have a multi-month drug-fueled orgy in the back of a stolen u-haul? heh
[22:54:51] <furrywolf> if you can afford thousands of dollars of toys and tens (or hundreds) of thousands of dollars of drugs, why steal a u-haul to have your orgy in, rather than just buy one, or rent a hotel room?
[22:57:48] <CaptHindsight> the stolen vehicle probably adds to the excitement
[23:00:58] <furrywolf> ohh, baby! run my VIN! RUN MY VIN!!!
[23:22:30] <furrywolf> bbl, wolfy bedtime
[23:26:35] <CaptHindsight> anyone have a favorite electroformer?
[23:34:22] <LatheBuilder_2> sry no. been dabbling in reverse electroforming though. CaptHindsight
[23:35:27] <LatheBuilder_2> looking for someone to make custom bellows?
[23:35:39] <LatheBuilder_2> bellows couplers rather
[23:41:03] <CaptHindsight> LatheBuilder_2: reverse electroforming? acid?
[23:41:45] <CaptHindsight> electropolishing?
[23:41:48] <LatheBuilder_2> CaptHindsight, electrochemical machining.
[23:42:31] <Jymmm> electroplating / electroetching ???
[23:43:32] <LatheBuilder_2> essentially electroplating in reverse with a very small controlled area of removal. A little like EDM but the electrodes never wear.
[23:43:52] <Jymmm> LatheBuilder_2: that would be electroetching
[23:44:50] <LatheBuilder_2> yes, but with etching you are merely masking a 2d surface where you want to keep material.
[23:45:55] <LatheBuilder_2> ECM is a little odd in its applications, but where it shines it is unbeatable.
[23:46:24] <CaptHindsight> https://en.wikipedia.org/wiki/Electrochemical_machining
[23:47:32] <CaptHindsight> http://www.substech.com/dokuwiki/doku.php?id=electrochemical_machining
[23:48:22] <LatheBuilder_2> EDM ate ECM's lunch several decades back. I've been nibbling at a wire ECM here and there
[23:50:07] <Jymmm> CaptHindsight: So, instead of a wire, it's using the electrolyte as the "tooling" (so to speak)
[23:50:12] <CaptHindsight> I want to build very think wall complex parts from metal by using a mandrel that dissolves in a solvent after the metal is formed
[23:50:41] <CaptHindsight> think/thin
[23:51:50] <CaptHindsight> the mandrel is printed with a DLP/LCD printer
[23:51:51] <LatheBuilder_2> CaptHindsight, does it need to dissolve in solvent or might low melt alloys be tolerable? something like cerrosafe
[23:51:58] <Jymmm> CaptHindsight: It sounds liek you are descrubing an "additive" process (like 3d printer), instead of a subtractive one (milling)
[23:52:26] <LatheBuilder_2> ahh. acceptable to flash plate your form if it is not conductive enough?
[23:52:30] <Jymmm> ...but the ECM is a a subtractive one
[23:53:25] <LatheBuilder_2> Jymmm, (he is talking about an additive process. I derailled the conversation with the bit about my hobby pursuit)
[23:53:50] <Jymmm> LatheBuilder_2: ah
[23:53:55] <CaptHindsight> I'm just looking for electroformers
[23:54:10] <Jymmm> I'm still looking for a video of this
[23:54:39] <Jymmm> I saw one, but that was basically electroplating imo.
[23:56:05] <CaptHindsight> electroforming is just thicker metal
[23:56:38] <CaptHindsight> plating is thin maybe a few microns
[23:57:02] <CaptHindsight> electroforming may be mm
[23:57:05] <Jymmm> Heh, depening on the amperage =)
[23:57:31] <LatheBuilder_2> http://www.servometer.com/products/precision-electroforms/
[23:57:40] <LatheBuilder_2> servometer might make what you need
[23:57:54] <Jymmm> I totally destroeyed SS in 8 minutes not realizing it
[23:58:53] <Jymmm> and I only had to go through 5 power supplies before I found one that didn't bitch and blew the circuit breaker =)
[23:59:02] <Jymmm> blow*
