Back
[00:22:19] <MacGalempsy> well, im out too. good night
[01:24:17] <XXCoder> renesis: yeah
[02:18:43] <Deejay> moin
[02:19:48] <XXCoder> hey
[02:33:22] <trentster> Hey all - anyone know why UI still says "home all" even tho I have homing stuff commented out for Z axis in ini file
[02:34:08] <trentster> I have prox sensors on X and Y with sequence Y=0 then X=1 but UI still is waiting for Z to autohome?
[02:35:53] <archivist> have you left Z (its number) in the sequence line
[03:35:59] <Contract_Pilot> Lathe evening.
[03:45:32] <archivist> pneumatic morning
[03:45:46] <XXCoder> playinh neverputt game
[03:45:51] <XXCoder> its fun lol been a while
[03:46:27] <archivist> I need to pipe up air to the CMM to play with it
[03:55:11] <XXCoder> dammit I keep sending ball off into void lol
[04:17:10] <XXCoder> nice neverputt has backup for ball constantly moving so unable to putt again. ball just hovers up a little and stops
[04:38:36] <ganzuul> http://i.imgur.com/FyDoSHd.jpg
[04:41:29] <Praesmeodymium> are they balanced as well as looking cool?
[04:44:45] <XXCoder> Praesmeodymium: good question
[04:44:51] <XXCoder> I see cuts wasnt counterbalanced
[04:44:57] <XXCoder> slight bias
[04:45:16] <XXCoder> chamfers do affect the odds
[04:45:27] <XXCoder> thats why castino dice is all very shark edged
[04:45:30] <XXCoder> sharp
[04:45:47] <XXCoder> so my answer is yes, but probably dont matter.
[04:46:46] <XXCoder> if I designed that dice I would make it have far less deep grooves. less bias towards ligher side up
[04:50:08] <Praesmeodymium> well those arent casino dice... and gamers tend to like biased dice tbh
[04:50:09] <ganzuul> hmm
[04:50:37] <XXCoder> indeed like I said it probably dont matter
[04:50:47] <XXCoder> players tend to not care about .001% bias
[04:50:47] <ganzuul> If you improve them, you can call them your own. So it's not blatant copycatting.
[04:51:12] <XXCoder> casinos do. they even counterbalance the damples
[04:51:27] <XXCoder> so its perfect 1/6 chance per side. well very close anyway.
[04:51:58] <Praesmeodymium> yeah they make a huge deal about how not cheaty they are dont they lol
[04:52:13] <XXCoder> they have to, in order to loosen wallets
[04:52:21] <XXCoder> if theres shady stuff they lose business.
[04:52:59] <XXCoder> gambling workers make LOT of money but highly stressful.
[04:53:56] <ganzuul> I once won 35 times in a row on blackjack. Betted 1 euro per round...
[04:54:16] <ganzuul> I don't gamble a lot...
[04:55:09] <XXCoder> i don gamble much, even with money I can afford to lose.
[04:56:39] <XXCoder> ganzuul: you made em?
[04:56:45] <XXCoder> looks pretty darn ool
[04:56:46] <XXCoder> cool
[04:56:47] <ganzuul> XXCoder: no
[04:57:15] <XXCoder> people with em can make it
[04:57:24] <ganzuul> Thinking about making roleplaying dice.
[04:57:25] <XXCoder> *mill machine or cnc whatever
[04:57:38] <XXCoder> theres special turn picking dice
[04:57:45] <XXCoder> it cannot be a tir
[04:57:47] <XXCoder> *tie
[04:57:54] <ganzuul> hm
[04:58:09] <XXCoder> lemme find it
[04:58:47] <XXCoder> btw http://www.dicecollector.com/DICEINFO_WHAT_SHAPES_DO_DICE_HAVE.html lol
[04:59:48] <XXCoder> found it.
[04:59:49] <XXCoder> http://mathsgear.co.uk/products/go-first-dice
[05:00:08] <XXCoder> its pretty amazing. 4 dices for 4 players, it won't tie to each other
[05:10:02] <XXCoder> I was wondering why only 4. its apparently very diffult. (link is in last link I posted)
[05:16:59] <XXCoder> ganzuul: nerd eh lol
[05:17:15] <ganzuul> aaah, yup ;)
[05:17:29] <XXCoder> math problem is definitely interesting.
[05:25:47] <Wolf_Mill> squaring up stock is sooo much fun...
[05:28:41] <XXCoder> awesome to turn messy block into nice and cubic shape
[05:29:30] <Wolf_Mill> would be easier if my machine cut things square lol
[05:30:16] <XXCoder> yeah but then theres trick a little
[05:30:35] <XXCoder> make sure to flip it only one way for example, so it slants same way therefore square
[05:30:40] <XXCoder> *parallel
[05:30:49] <XXCoder> its bit more tricky for other 2 sides
[05:31:13] <XXCoder> ganzuul: more cool dice lol for example element dice. http://www.ericharshbarger.org/dice/#compass
[05:31:26] <Wolf_Mill> yeah, I work everything off the fixxed jaw
[05:31:38] <XXCoder> scroll up a little to get card suits dice. wonder why
[05:33:05] <Wolf_Mill> annoying part is flycutting these blocks on this tiny machine
[05:33:21] <Wolf_Mill> I'm waiting to break the gear train in the head
[05:35:47] <Wolf_Mill> only 6061-t6 1.5" x 3" x 54mm...
[05:36:17] <XXCoder> lol cheater dice. two 6s and no 1
[05:39:41] <XXCoder> woodgears now has gear creator website. nice
[06:27:30] <ganzuul> Irrational numbers dice. Nice. :)
[06:27:56] <XXCoder> you can make your own custom
[06:28:07] <XXCoder> though I'm not certain what I would want lol
[06:29:25] <ganzuul> I want dice with some sort of optical effect.
[06:29:26] <XXCoder> Symmetric Pips not bad
[06:29:35] <ganzuul> Like a prism, or lenses.
[06:29:44] <archivist> or holographic
[06:29:49] <ganzuul> hmm
[06:29:59] <ganzuul> That'd be easier, actually.
[06:31:11] <archivist> I could imaging holographic tape with numbers on being available
[06:35:56] <ganzuul> Too easy. >:|
[06:36:36] <XXCoder> I remember one dice that has another dice inside it
[06:36:46] <XXCoder> its basically rolling two dice for like one die
[08:04:59] <ganzuul> \o/
[08:05:13] <ganzuul> http://imgur.com/pnH5YxG
[08:06:07] <ganzuul> I ordered a cross slide which will let me add another inch of travel.
[08:06:22] <XXCoder> thats what she needed.
[08:06:31] <ganzuul> That brass is 80mm in dia.
[08:08:38] <ganzuul> Also, getting a backplate for 125mm chuck.
[08:09:36] <Wolf_Mill> need a non-pos tool holder
[08:09:41] <ganzuul> I found a seller in Germany who produces a compatible 125mm indepentent 4 jaw chuck for a reasonable price, but they don't have freight listed...
[08:09:47] <ganzuul> Wolf_Mill: Absolutely.
[08:10:00] <ganzuul> Wolf_Mill: I plan on spending about 200 euro on that.
[08:10:37] <ganzuul> Getting an AXA one and a different compound slide, so it'll fit and I can get bigger tools low enough.
[08:10:41] <Wolf_Mill> i've been meaning to check to see if that shars toolholder uses the same size as the ones I already have
[08:12:34] <ganzuul> BTW, no chatter if I just keep bravely feeding the tool into the work, even if the cross slide is loose.
[08:13:20] <fenn> how about making your own wedge toolpost and holders?
[08:13:29] <fenn> too much too fast?
[08:13:38] <Wolf_Mill> :P
[08:13:41] <ganzuul> fenn: Pretty much.
[08:14:37] <ganzuul> I saw plans for this plate on littlemachineshop.com which should make the milling attachement usable.
[08:14:51] <Wolf_Mill> I'm so waiting for one of the x1 spindle drive gears to blow up right now...
[08:15:42] <Wolf_Mill> sad part is i'm only fly cutting w/ a 0.05mm doc...
[08:16:27] <ganzuul> Maybe a shorter overhang would reduce the shock?
[08:16:29] <fenn> you can 3d print another one hahahahaha
[08:16:52] <fenn> oh wait that was the lathe
[08:16:59] <Wolf_Mill> yeah, the gears on thingerverse? I already printed lathe gears lol
[08:17:59] <Wolf_Mill> I still need to find a vfd/motor combo for the x2 head
[08:20:35] <Wolf_Mill> I did get a air cylinder off ebay last night for the X2 drawbar
[08:24:51] <Wolf_Mill> 3"bore w/ 3/4" stroke, I should be able to bolt it direct to the X2 head :D
[10:22:14] <CaptHindsight> http://www.3ders.org/articles/20150925-carima-unveils-super-high-speed-c-cat-continuous-additive-3d-printing-tech.html (using lower viscosity photopolymers)
[10:23:47] <CaptHindsight> https://www.youtube.com/watch?v=wxFjRzS5OlQ
[10:27:04] <CaptHindsight> the Z continuously moves up and the projector just changes images synced to the Z position
[10:27:13] <fenn> at least show the part after all that.. anticlimax
[10:28:14] <CaptHindsight> it's a Eiffel Tower
[10:28:55] <CaptHindsight> poor choice but it's become a standard in SLA
[10:29:26] <fenn> yeah but i'd like to see the print quality
[10:29:41] <CaptHindsight> it's fine
[10:30:26] <CaptHindsight> there's no layering unless you can't figure out how to create the images and sync them
[10:31:15] <chris_99> what kind of Z-axis are they using, are they driving with steppers or..?
[10:31:35] <CaptHindsight> andy has a patch do do it with Linuxcnc
[10:32:12] <CaptHindsight> the Z can be made with whatever motors that work
[10:33:03] <fenn> really, viscosity was the limiting factor?
[10:33:39] <CaptHindsight> viscosity, cure rate and slope
[10:34:05] <fenn> slope?
[10:34:18] <CaptHindsight> the viscosity has to be low enough so that the photopolymer can flow under the part as its drawn up away from the surface of the vat
[10:36:19] <CaptHindsight> slope is the curing depth
[10:37:24] <CaptHindsight> too much and you don't get low enough Z resolution
[10:37:49] <fenn> too little and the resin can't get sucked in
[10:38:02] <fenn> or it sticks to the surface
[10:38:20] <CaptHindsight> they also don't tell you that parts with larger surface areas will print slower since the resin needs to flow under the part
[10:38:46] <CaptHindsight> thats why the tower was chosen for the demo
[10:39:10] <CaptHindsight> thin structure with lots of open space
[10:39:26] <fenn> maybe you could dynamically generate resin channels that never repeat exactly
[10:39:45] <CaptHindsight> a 4" dia cylinder will take longer with the same resin
[10:41:32] <CaptHindsight> some group claiming that it can only be done with their magic vat material raised ~$140M so far
[10:42:10] <fenn> the power of oxygen
[10:42:18] <fenn> drink hydrogen peroxide!
[10:42:25] <CaptHindsight> http://www.3ders.org/articles/20150820-hot-3d-printing-startup-carbon3d-raises-from-google-ventures-and-yuri-milner.html
[10:43:12] <CaptHindsight> oh and it only works with resins where oxygen acts a polymerization inhibitor
[10:43:30] <fenn> we're nowhere near the limits of light directed solidification
[10:43:37] <pcw_home> how linear is the photo sensitivity if they was a threshold you could use laser focus to cure below the surface
[10:44:04] <pcw_home> ICs are still made with light directed solidification
[10:44:09] <fenn> two photon photo-polymerization is a thing that exists
[10:44:13] <CaptHindsight> pcw_home: thats how 2-photon polymerization works
[10:44:25] <CaptHindsight> it only cures at the point of focus
[10:44:46] <pcw_home> avoids the flow issue
[10:45:05] <CaptHindsight> vs whatever the beam hits
[10:45:25] <pcw_home> harded 1mm above the window
[10:45:30] <pcw_home> harden
[10:45:52] <CaptHindsight> if the resin is relatively transparent
[10:47:14] <CaptHindsight> won't have much penetration is the resin is filled with solids such as pigments, graphite, carbon, silica etc
[10:47:20] <CaptHindsight> is/if
[10:48:39] <CaptHindsight> but 2-photon polymerization gets you down to ~200nm features in XYZ
[10:50:03] <t12> mornin
[10:54:12] <CaptHindsight> t12: know anyone to fund my magic vat printer? I'll only need $70M
[10:54:39] <t12> lol
[10:54:47] <t12> need to do some ted talks first
[10:54:54] <CaptHindsight> ah
[10:54:55] <t12> will it cure cancer death and aging?
[10:55:05] <CaptHindsight> certainly
[10:55:38] <CaptHindsight> should be able to do it in the next 80-160 years, no problem
[10:56:29] <t12> very over that world at the moment
[10:56:34] <t12> max cynicism
[10:56:38] <CaptHindsight> heh
[10:57:26] * Jymmm hands CaptHindsight $140M - I'll take two with free OVERNIGHT shipping, whats the tracking number?
[10:58:03] <CaptHindsight> you can pick your own scent for each print as well
[10:58:26] <t12> pre orders!
[10:58:34] <CaptHindsight> see
[10:58:49] <t12> using big data
[10:59:13] <t12> we predict which test print model you would have used before never using the printer again
[10:59:18] <t12> and make it for yoy!
[10:59:19] <CaptHindsight> wonder what the Paypal fees are on $140M
[10:59:32] <Jymmm> Vaporware went out in the 90's man
[10:59:49] <t12> yeah weve moved on to vaporcompa ies
[10:59:57] <t12> vaporcompanies even
[11:00:04] <t12> corps?
[11:01:40] <CaptHindsight> 3D systems and Stratasys have lawsuits against them now for BSing their investors
[11:02:03] <t12> ya
[11:02:08] <CaptHindsight> profits were 1/3 their forecasts
[11:02:20] <t12> though its kinda
[11:02:21] <t12> like
[11:02:28] <t12> ok your investment didny work
[11:02:37] <t12> thats pretty common
[11:02:51] <t12> just accept the lost lottery ticket
[11:03:20] <CaptHindsight> who would have thought that their CEO's would lie?
[11:03:45] <t12> maybe they have real evidence that they just ignored/altered market research
[11:04:22] <t12> isnt this specifically over makerbot tho
[11:04:40] <t12> i think bre pettis is listed on the stratasys suit
[11:04:51] <CaptHindsight> no, makerbot is about selling known to be faulty printers
[11:05:24] <CaptHindsight> 3D systems just pulled figures out of someones butt
[11:06:08] <CaptHindsight> http://3dprintingindustry.com/2015/06/16/investors-seek-class-action-lawsuit-against-3d-systems-for-weak-earnings/
[11:06:12] <t12> do you think tbe carbon3d claims are bs
[11:06:43] <CaptHindsight> t12: it works, it just doesn't need their patented vat film to work
[11:07:36] <CaptHindsight> other materials work for the vat
[11:07:46] <CaptHindsight> and it also works with top projection
[11:08:39] <CaptHindsight> the carbon scam is that it needs their magic transparent oxygen permeable membrane
[11:09:10] <t12> does it actually speed stuff up with their chemistry
[11:09:21] <CaptHindsight> they have nothing
[11:09:24] <pcw_home> Nooo It _Needs_ their patented voodoo
[11:09:29] <CaptHindsight> you can do it
[11:09:49] <t12> a relative developed a bunch of those selective permiable membranes at ge
[11:10:45] <CaptHindsight> I forget when the Envisiontec patent runs out, maybe it already has
[11:10:57] <CaptHindsight> they patented the top projection
[11:11:50] <CaptHindsight> but that might be with a laser and the DLP patent is still active
[11:13:07] <CaptHindsight> the problem that Carbon has is that they are limited to a small range of materials
[11:13:50] <CaptHindsight> but printers like that will find niches
[11:15:06] <CaptHindsight> short runs of plastic parts (few K's) since tools take weeks to make for injection molding
[11:16:36] <zeeshan> that carima 3d printer is actually fast!
[11:16:36] <zeeshan> nice
[11:17:39] <zeeshan> two weeks??!~1
[11:17:44] <zeeshan> thats quick for plastic injection parts :P
[11:18:34] <zeeshan> speaking of 3d printers
[11:18:41] <zeeshan> its funny my friends delta printer
[11:18:45] <zeeshan> isn't anywhere close to being precise
[11:18:50] <zeeshan> all the dimensions are completely out randomly
[11:18:59] <zeeshan> long live machining!
[11:19:09] <t12> solids are nice
[11:20:13] <CaptHindsight> say you can 3d print 100 parts an hour, so 24 x 7 = 168 x 100 parts = 16.8k parts before the tool shows up
[11:21:11] <CaptHindsight> so it's a fit for small runs if the materials are suitable
[11:22:38] <ganzuul> Carbide make HSS seem soft...
[11:23:13] <zeeshan> haha ganzuul
[11:23:14] <zeeshan> it does!
[11:23:20] <CaptHindsight> zeeshan: did you actually measure the parts to see by how far?
[11:23:31] <zeeshan> yea capt
[11:23:31] <zeeshan> i did
[11:23:36] <zeeshan> cause iove been machining the real deals
[11:23:41] <CaptHindsight> FDM is like pottery
[11:23:52] <zeeshan> the holes are out by 50 thou
[11:23:53] <zeeshan> or so
[11:24:04] <zeeshan> they're inconsistently out
[11:24:09] <zeeshan> one hole is out by 50 thou
[11:24:13] <zeeshan> the other is out by 40 thou
[11:24:15] <zeeshan> both are the same size..
[11:24:37] <zeeshan> the overall dimensions are out randomly as well
[11:24:45] <zeeshan> by 100 thou for height
[11:24:49] <zeeshan> width 50 ish
[11:25:00] <zeeshan> length 60ish
[11:25:06] <CaptHindsight> you can do much better with FDM, it might be his printer or software
[11:25:26] <t12> deltas have spherical error right
[11:25:49] <t12> where positoning resolution deceases as you depart from some point?
[11:25:53] <zeeshan> honestly, you'd have to really convince me to show fdm is precise.
[11:25:57] <zeeshan> dlp i understand
[11:26:10] <zeeshan> but fdm looks inherently flawed
[11:26:15] <pcw_home> Yoda doesn't care
[11:26:21] <zeeshan> youre literally spreading glue everywhere
[11:27:05] <Tom_itx> neither do all the dildos that get printed
[11:27:09] <CaptHindsight> FDM/GGG has it uses, just not the ones the repcrapers go on about
[11:27:23] <malcom2073> You don't use FDM for parts that need precision, if so, you're doing it wrong zeeshan
[11:27:26] <zeeshan> CaptHindsight: if i was designing for fdm
[11:27:30] <zeeshan> i'd undersize everything
[11:27:33] <zeeshan> and machining em to spec after
[11:27:40] <zeeshan> i only intend to use it for casting purposes
[11:27:42] <zeeshan> for generating molds
[11:27:55] <CaptHindsight> molds or patterns?
[11:28:01] <zeeshan> one off molds
[11:28:30] <CaptHindsight> what are you going to cast?
[11:28:40] <zeeshan> (lost foam casting type of stuff)
[11:28:45] <zeeshan> where the plastic just burns off
[11:28:58] <pcw_home> better with DLP for that
[11:29:11] <zeeshan> pcw_home: i won't be owning a dlp at home anytime soon
[11:29:16] <zeeshan> gotta work with fdm likely
[11:29:18] <CaptHindsight> I made a water soluble photopolymer for that
[11:29:33] <zeeshan> CaptHindsight: different auto parts
[11:29:41] <pcw_home> fdm is just the wrong tool for that
[11:29:50] <zeeshan> its fine
[11:29:56] <zeeshan> you just need to machine your cast part after
[11:30:00] <zeeshan> which will be doing regardless after
[11:30:15] <zeeshan> i just need overall shape there
[11:30:40] <CaptHindsight> yeah, if you're not making molds in volume
[11:30:43] <pcw_home> if you like slow and inaccurate, its the tool of choice
[11:31:04] <zeeshan> pcw_home: you didnt mention cheap
[11:31:05] <zeeshan> :)
[11:31:10] <CaptHindsight> hours for the GGG mold, machine for another 30 minutes
[11:31:26] <zeeshan> yea most of the stuff ill be focusing on will be very small runs
[11:31:35] <zeeshan> i really don't want to do a lot of production anymore.
[11:31:39] <zeeshan> ill outsource the production
[11:32:00] <zeeshan> i want to make sure the product works in real life
[11:32:02] <zeeshan> then outsource
[11:32:43] <Tom_itx> zeeshan gettin caught up on them?
[11:32:50] <pcw_home> not sure that a DLP system should be a whole lot more expensive
[11:33:02] <zeeshan> pcw_home: fdm seems be around 1500 bux for a decent one
[11:33:04] <zeeshan> dlp is in the 10's
[11:33:09] <zeeshan> to 40's
[11:33:21] <CaptHindsight> nah DLP is the same or lower
[11:33:23] <zeeshan> Tom_itx: http://i.imgur.com/ZU4JV8C.jpg
[11:33:27] <zeeshan> http://i.imgur.com/aUxi6fO.jpg
[11:33:29] <CaptHindsight> depending on res
[11:33:45] <CaptHindsight> the projector is the most expensive part
[11:34:00] <zeeshan> CaptHindsight: how much
[11:34:07] <zeeshan> find me a good one for 1500 :P
[11:34:20] <Tom_itx> is the fixture working as expected?
[11:34:24] <zeeshan> Tom_itx: yes
[11:34:27] <CaptHindsight> zeeshan: do you want off the shelf?
[11:34:33] <zeeshan> if i were to go back
[11:34:42] <zeeshan> i needed to design the mandrel to both expand
[11:34:43] <zeeshan> and contract
[11:34:47] <zeeshan> so they're easier to pull out
[11:34:53] <Tom_itx> yeah
[11:35:07] <zeeshan> but its not bad for a first time expanding mandrel job in wood :P
[11:35:16] <zeeshan> CaptHindsight: yes :P
[11:35:22] <zeeshan> or used market
[11:35:38] <zeeshan> its on the list after lathe retrofit, atc for mill
[11:35:39] <zeeshan> :P
[11:36:07] <Tom_itx> i bet your shop floor is colorful
[11:37:07] <CaptHindsight> looks like epoxy with 50's-60's speckle pattern
[11:37:24] <CaptHindsight> we had a kitchen table like that
[11:37:39] <zeeshan> the 6 on the right
[11:37:45] <zeeshan> are more plastic than wood
[11:37:54] <zeeshan> all the ones on the left are more like stablized wood
[11:38:01] <zeeshan> so im machining them at different feeds and speeds
[11:38:06] <zeeshan> the plastic i can rip through
[11:38:13] <zeeshan> the wood i gotta reduce by 25%
[11:38:41] <CaptHindsight> do you get the wood pre-impregnated?
[11:38:43] <pcw_home> ~3K seems to be the center for low cost SLA
[11:40:09] <zeeshan> CaptHindsight: yes
[11:40:25] <zeeshan> it makes machining more stable - literally
[11:40:28] <zeeshan> in comaprison to regular wood
[11:40:54] <zeeshan> it also helps reduce the dust
[11:41:40] <CaptHindsight> t12: are you saying that by giving a TED talk it actually adds to your credibility in the eyes of investors?
[11:41:50] <zeeshan> lol @ ted talk
[11:41:50] <zeeshan> hahaha
[11:41:55] <zeeshan> they used to be good
[11:41:59] <zeeshan> now they allow propoganda
[11:42:57] <CaptHindsight> hmmm, TED talk, 100K+ twitter and facebook fans/followers
[11:43:21] <CaptHindsight> appeal to the masses
[11:44:24] <jthornton> anyone know how to append the PATH in debian wheezy and it stick? everything I've tried either won't be there after a boot or it doesn't add the path
[11:45:43] <magnifikus> anyone experienced with the hal driver layer here? would like to use the trinamic ramp generators via SPI
[11:45:52] <magnifikus> but not sure if thats even possible with linuxcnc
[11:46:12] <magnifikus> so you tell it, how many steps and the acceleration etc values
[11:46:14] <Tom_itx> such difficult questions on a Sunday morning...
[11:46:20] <magnifikus> sry :D
[11:46:25] <magnifikus> but i find the drivers so sexy
[11:46:37] <pcw_home> jt: .bashrc?
[11:47:03] <jthornton> not tried that, put in the home directory?
[11:47:13] <ssi> morn
[11:47:20] <pcw_home> should already be there
[11:48:06] <pcw_home> magnifikus: look at an existing hal component
[11:48:11] <jthornton> ah yes it is there
[11:52:57] <magnifikus> pcw_home: yeah i did with picnc2, but i was not sure if its even possible
[11:53:18] <magnifikus> so if you say not possible or way to complicated i save the time :)
[11:55:07] <ganzuul> Stanley knife blades are harder than HSS too. :o
[11:55:14] <pcw_home> Its surely possible, how will the host part of the SPI work?
[11:55:46] <magnifikus> ah im running currently on odroid with picnc2
[11:55:49] <magnifikus> that works nicely
[11:55:57] <magnifikus> so a pic32 is generating pulses
[11:56:19] <magnifikus> but my drivers evaporated, so im looking into a decent solution, like the tmc5130a
[11:56:42] <magnifikus> it can consume step pulses, but i thought why not use the spi interface and profit from the internal stepgens
[11:57:05] <magnifikus> and the picnc2 is using spi too
[11:58:04] <pcw_home> beware that un-isolated SPI to a motor driver is very susceptible to noise
[11:59:14] <magnifikus> my layout i using 5v level to the drivers and isolators from TI to and from the odroid
[11:59:22] <pcw_home> if the motor driver in on the same card with the same ground plane its more likely to work than if its a cabled interface
[11:59:23] <magnifikus> specced at 1mhz
[12:00:29] <magnifikus> maybe i try it for the challenge :)
[12:00:45] <CaptHindsight> jepler had fun getting SPI working on the odroid
[12:00:56] <CaptHindsight> lots of noise
[12:01:11] <pcw_home> lots of latency issues IICRC
[12:01:26] <CaptHindsight> plus didn't odroid not put a ground pin on the SPI header
[12:01:43] <CaptHindsight> it was something like signals only
[12:01:46] <magnifikus> eh c1 has one
[12:01:52] <magnifikus> using picnc on it atm
[12:01:58] <magnifikus> works fine
[12:02:08] <CaptHindsight> \0/
[12:02:49] <pcw_home> Yeah but most dev boards pretty much ignore SI issues (1 ground for many I/O pins for example)
[12:03:15] <magnifikus> yeah thats true
[12:04:34] <magnifikus> oh it has 7 gnd pins on its 40 pins
[12:05:11] * jthornton gives up trying to learn go, I can't even set the path environment in debian wheezy running mate
[12:05:30] <magnifikus> but the SI can be a bitch
[12:05:35] <CaptHindsight> http://www.trinamic.com/products/integrated-circuits/integrated-motion-controller-stepper-driver/tmc5130
[12:05:43] <magnifikus> esp if you got an crc error on one driver
[12:05:48] <magnifikus> the others start moving
[12:06:22] <CaptHindsight> good for making parts with random variations
[12:06:36] <CaptHindsight> handmade quality
[12:07:12] <magnifikus> i cannot afford a mesa card for our university lab :D
[12:08:22] <magnifikus> http://snag.gy/dN9Qf.jpg first try but will turn drivers 180° for better si on the digital pins
[12:10:16] <magnifikus> i got artix 7 fpgas at hand in the lab but no time to impelement something proper into them :D
[12:11:53] <CaptHindsight> 2 layer board?
[12:12:27] <magnifikus> test pcb yeah i can etch that inhouse
[12:13:09] <CaptHindsight> wide power traces but narrow ground traces
[12:13:38] <magnifikus> nah the ground planes are not visible
[12:15:47] <magnifikus> http://snag.gy/MtQif.jpg
[12:15:57] <magnifikus> top looks the same but you cant see anything anymore ^^
[12:16:25] <CaptHindsight> that makes more sense
[12:17:21] <magnifikus> http://snag.gy/AfcKz.jpg top
[12:18:46] <CaptHindsight> jumpers are your friend to help keep the floods/pours filled
[12:19:32] <magnifikus> yeah its totaly not final, 3 hours
[12:20:04] <magnifikus> the right side is empty on purpose, cause isolated interface
[12:21:54] <magnifikus> but if professionals say the tmc is shit, i can just stay with the picnc and build mosfet drivers with controller
[12:22:03] <magnifikus> just classic 16x microsteps
[12:40:20] <magnifikus> oh and i want to add a central 16mhz clock for all chips so they are clocked all the same :P
[13:35:53] <ganzuul> Anybody using a loupe, magnifying glass or such for their work?
[13:43:59] <cradek> I use lots of that kind of thing
[13:44:29] <cradek> also stereo microscope sometimes
[13:44:49] <archivist> ganzuul, more often I use a stereo zoom microscope
[13:45:06] <ganzuul> hmm
[13:45:12] <cradek> why?
[13:45:13] <ganzuul> How much zoom?
[13:45:23] <ganzuul> Thinkign about getting a pair of these: http://www.ebay.co.uk/itm/Silver-Dentist-Dental-Loupes-Head-Light-Lamp-2-5-3-5-320-420-Surgical-glass-/191350456511
[13:45:25] <archivist> also just chuck another pair of reading glasses on
[13:45:32] <ganzuul> Cheaper than stereo microscope.
[13:46:34] <archivist> the CMMs trip from van to garage http://www.collection.archivist.info/searchv13.php?searchstr=cmm
[13:46:53] <cradek> I have add5.00 bifocals I wear for very small/close work
[13:49:03] <ganzuul> I'm thinking about ways to avoid getting my eyes close to sharp hot fast pointy bits...
[13:52:18] <cradek> that's why we have polycarbonate
[13:54:29] <furrywolf> work on parts large enough you don't need to get close to them. :)
[13:55:07] <archivist> run the lathe fast enough and the chips chase you
[13:55:38] <zeeshan> archivist:
[13:55:39] <zeeshan> holy cow
[13:55:42] <zeeshan> you werent kidding, you got a cmm!
[13:55:43] <zeeshan> nice!
[13:55:47] <archivist> managed to get them on the cupboard behind the tailstock once :)
[13:56:11] <archivist> zeeshan, me kid...neva
[13:56:21] <cradek> those concrete blocks are frightening
[13:56:23] <archivist> well sometimes
[13:56:24] <cradek> that is a nice level
[13:56:36] <cradek> I'm surprised a van could carry it
[13:56:49] <archivist> those levels are showing twist
[13:57:21] <archivist> the granite is only 140 kg
[13:57:49] <zeeshan> i see that youre making use of my level
[13:58:04] <archivist> so probably 300 kg and anothr 300 for the rack (heavy beast)
[13:58:07] <cradek> oh the two settings of the level are the same machine position?
[13:58:15] <archivist> yes
[13:58:29] <cradek> interesting!
[13:59:35] <archivist> now really happy with the levels as I expected the cmm to be better than them, but the original spec was only 200 microinches
[14:00:30] <archivist> van is a 3.5 ton gross iirc
[14:01:05] * ganzuul is also impressed with the van
[14:01:28] <archivist> its a leaky heap ready for the scrap yard
[14:05:23] <furrywolf> http://fw.bushytails.net/battsinvan01.jpg
[14:05:44] <archivist> now that is van abuse :)
[14:05:56] <furrywolf> nah. that's a little under its weight rating. :)
[14:05:59] <archivist> was it on the bump stops
[14:06:07] <furrywolf> not even close.
[14:06:21] <furrywolf> I got a 1-ton superduty, just so I could do stuff like that. :)
[14:06:34] <furrywolf> big axles, big springs.
[14:07:29] <ganzuul> Was looking at new vans, could not find weight ratings? ¯\(º_o)/¯
[14:07:33] <archivist> I had a smoother ride that usual on Friday with the CMM in (and the concrete blocks)
[14:07:59] <furrywolf> Big axles, big springs, big transmission, big V8... 11 miles per gallon.
[14:08:16] <furrywolf> what's the cmm weigh?
[14:08:17] <archivist> I get 22 to the gallon in the heap
[14:08:38] <archivist> I am guessing about 300 kg
[14:08:49] <furrywolf> oh, that's nothing.
[14:08:50] <furrywolf> lol
[14:09:27] <archivist> the rack and blocks made the weight up a "bit"
[14:09:50] <furrywolf> my van is supposed to have 15 passengers in it... it's appropriately beefy.
[14:15:29] <furrywolf> it's the van version of a superduty truck... same drivetrain.
[14:16:25] <furrywolf> bbl, using said van to move a water heater and a bunch of stainless shelving. :)
[14:20:26] <Tom_itx> ganzuul, that magnifier looks heavy to wear
[14:21:04] <Tom_itx> i use a 7x45 zoom binocular scope along with other magnifiers depending on the work
[14:26:19] <JT-Shop> lol somehow I've set the path to stick on this debian wheezy but can't for the life of me remember how or where I set it
[14:26:34] <JT-Shop> with 50 possible choices according to google...
[14:27:11] <archivist> what path?
[14:27:27] <JT-Shop> the executable path
[14:28:57] * JT-Shop tried grep to see if I can find it
[14:29:40] <archivist> the standard is in /etc somewhere and your user local is added in .bashrc or whatever you are using
[14:30:19] <archivist> it extends the standard paths if you want it to
[14:30:27] <pcw_home> .profile has an example of adding a local path option
[14:34:16] <JT-Shop> I tried .profile, .bash_profile, export PATH=$PATH:/usr/local/go/bin and a few more in etc something
[14:36:30] <archivist> echo $PATH will show you what is knows about
[14:37:46] <pcw_home> did you add you new path to .profile?
[14:37:55] <pcw_home> your
[14:38:26] * ganzuul has completed his first facing operation!
[14:39:16] <ganzuul> shiny :3
[14:39:32] <CaptHindsight> did any of you have a machine shop class in HS?
[14:40:00] <ganzuul> Tom_itx: That's a good point... There is a version of the same without the light.
[14:40:20] <Tom_itx> CaptHindsight i had somewhat of one
[14:40:23] <pcw_home> if you read . profile is says its not used if .bash_profile or .bash_login exist
[14:40:30] <ganzuul> Tom_itx: Aren't those just regular binoculars though?
[14:40:53] <cradek> JT-Shop: you should install the go language package (golang)
[14:40:59] <Tom_itx> CaptHindsight, and mechanical drawing etc
[14:41:06] <CaptHindsight> I wonder if they still exist
[14:41:07] <cradek> JT-Shop: I don't know what you've done to get /usr/local/go but it was the wrong thing
[14:41:09] <ganzuul> The 7x45 that is
[14:41:14] <Tom_itx> CaptHindsight, i'm not sure
[14:41:25] <CaptHindsight> Tom_itx: heh, yeah I took a few years of that
[14:41:28] <Tom_itx> i know they have a room full of Haas at the trade school
[14:42:25] <Tom_itx> along with manual machines etc
[14:43:49] <CaptHindsight> I went to HS with the first lady, we only had a woodshop and TV studio
[14:44:16] <CaptHindsight> my friends had a HS machine shop that was really complete with manual tools
[14:44:17] <Tom_itx> they were 'building' the metal shop up when i was there
[14:44:23] <Tom_itx> they already had a wood shop
[14:44:43] <CaptHindsight> they also had a complete auto shop
[14:45:00] <Tom_itx> i went to a smaller HS
[14:45:19] <CaptHindsight> oh yeah we had a photo lab as well
[14:45:27] <Tom_itx> they had one of those
[14:45:33] <Tom_itx> 'publications' class
[14:45:39] <CaptHindsight> and they still taught typesetting by hand
[14:46:41] <CaptHindsight> and the computer lab a 2 terminals to teach BASIC
[14:46:43] <JT-Shop> cradek, I did install the go language package but part of the instructions is to append the PATH variable with the install location
[14:47:09] <JT-Shop> the install instructions I followed https://golang.org/doc/install
[14:47:40] <cradek> no the debian package
[14:47:45] <cradek> apt-get install golang
[14:48:24] <JT-Shop> that's probably why I'm have so much fun
[14:48:38] <CaptHindsight> I took a welding class at anther HS at night (gas and arc)
[14:48:56] <Tom_itx> yeah i took that as well. just stick and gas though
[14:49:09] <archivist> CaptHindsight, I had metalwork for a year at one school, the next said not enough want it you can do woodwork
[14:49:41] <CaptHindsight> I don't know if they still have them in the US
[14:49:53] <CaptHindsight> too dangerous
[14:50:02] <CaptHindsight> think of the children
[14:50:05] <archivist> make a name tag and use emery paper to get a mirror finish
[14:54:10] <archivist> 3d glue gun course probably now
[14:54:17] <CaptHindsight> lol
[14:54:54] <archivist> actually that is available in the local school!
[14:55:11] <Tom_itx> CaptHindsight, survival of the fittest
[14:55:33] <CaptHindsight> used to have: carpentry, cabinet making, and wood turning, foundry, forge, welding, coremaking and molding, machine shop and electric shop
[14:55:40] <Tom_itx> yeah the local vo tech just got a bunch of glue guns
[14:56:02] <CaptHindsight> + auto and welding
[14:56:15] <archivist> these days the local tech college has those types of courses
[14:57:16] <CaptHindsight> so they still do science experiments? besides growing seeds and similar safe projects
[14:57:29] <CaptHindsight> so/do
[14:57:31] <Tom_itx> like nukes?
[14:57:44] <CaptHindsight> clock making
[14:58:02] <jthornton> cradek, thanks that worked
[14:58:08] <archivist> clock making is only at about two colleges in the UK
[14:58:20] <Tom_itx> some crafts will just appear in history books
[14:58:23] <jthornton> I wonder why golang didn't just say use apt-get and install it on your debian box?
[14:58:58] <Tom_itx> jthornton, that would make your day too normal
[15:01:17] <CaptHindsight> heh in 1915 "the machine shop. It was equipped with 80 machines and 60 lathes cast and built at Lane"
[15:01:26] <CaptHindsight> 100 years later.....
[15:01:31] <archivist> CaptHindsight, most clock making is self taught with with a qualification from the BHI available by remote learning and some exams
[15:01:58] <CaptHindsight> glue gun printers
[15:03:31] <CaptHindsight> archivist: I was also poking fun at "clock making at school" after that kid was cuffed and held for hours for taking digital clock guts to school
[15:03:47] <archivist> you can cram a years BHI course in a few weeks if you can already draw and make metal things from a drawing
[15:04:14] <archivist> I did see that news item
[15:04:58] <CaptHindsight> I wasn't aware of BHI until now
[15:06:44] <archivist> your side has http://nawcc.org/
[15:07:26] <CaptHindsight> http://www.nawcc-index.net/Schools.php
[15:08:39] <CaptHindsight> tool maker is another soon to be lost craft in the US
[15:09:41] <archivist> dont see how as all the press and molding tools still need to be made
[15:11:24] <CaptHindsight> I was at the last Molding trade show, wasn't very big
[15:11:58] <CaptHindsight> http://www.amerimoldexpo.com/articles/post-show
[15:13:12] <archivist> but that claims "This total included a record number of exhibiting tool and mold manufacturers."
[15:14:58] <archivist> I think there is a perception that you can just throw some cam and a cnc into a pot these days and get an item made
[15:17:03] <CaptHindsight> what the CNC salesperson said :)
[15:17:30] <CaptHindsight> just load the material, program and GO
[15:18:02] * archivist hears a loud crash
[15:27:41] <CaptHindsight> http://impossible-objects.com/technology/ watch the video
[15:30:51] <_methods> impossible
[15:31:19] <CaptHindsight> yeah, shouldn't they be called "possible objects"
[15:31:27] <CaptHindsight> lies lieslies
[15:32:08] <CaptHindsight> I'm going to start a company that doesn't make impossible parts to prove it can't be done
[15:34:23] <_methods> hahaha
[16:10:58] <Deejay> gn8
[16:43:08] <furrywolf> anyone here ever pressure test natural gas plumbing? can you do a test with the meter still connected, or will backpressure make it unhappy/explodey?
[16:43:47] <Wolf_> close the valve first?
[16:44:53] <furrywolf> the meter only has a valve between it at the city, not between it and the building's plumbing.
[16:45:00] <furrywolf> said valve is, of course, closed.
[16:46:01] <Wolf_> should be fine then, I think you need to do a leak down test not really pressure…
[16:46:41] <furrywolf> you have to pressurize it to some higher pressure (I'm tempted to say >3psi) and wait some specified period of time (I'm tempted to say 10 minutes) without it dropping.
[16:47:31] <Wolf_> i don’t really remember, I only did a ng install once and I really didn’t do anything other then watch, and it was the line from the street to the meter...
[16:49:22] <furrywolf> we're putting back into service a system that's been disconnected for many years, and the brass appliance valves tweekered... so replacing the missing valves, then doing a pressure test to make sure there's no hidden leaks, leaks inside walls from the valve being removed, etc.
[16:49:42] <andypugh> The normal test is to open the main valve, watch the manometer level, close the valve, and make sure that the manometer doesn’t move.
[16:50:20] <andypugh> So, you pressure test with normal supply pressure.
[16:51:04] <furrywolf> I'm fairly sure the code requires a 3psi test...
[16:51:38] <andypugh> What is the supply pressure?
[16:51:52] <andypugh> (after the meter)
[16:52:03] <furrywolf> yes...
[16:52:04] <furrywolf> 406.4.1 Test pressure. The test pressure to be used shall be no less than 1 ½ times the proposed maximum working pressure, but not less than 3 psig (20 kPa gauge), irrespective of design pressure.
[16:53:04] <furrywolf> 7" WC
[16:53:06] <andypugh> OK, that’s rather odd. I have never seen a UK plumber over-pressure the system
[16:53:15] <furrywolf> I'm not in the UK. :P
[16:53:19] <Jymmm> makes sense to me
[16:53:36] <andypugh> Yes, but I can’t see them doing it anywhere. How would you do it?
[16:54:01] <Wolf_> so stuff in the UK blows apart if over pressure but doesn’t leak? :P
[16:54:13] <Jymmm> pump? compressed gas? Nitrogen tank?
[16:54:28] <andypugh> Why would it be over pressure? There is a regulator in the meter.
[16:54:46] <JT-Shop> there are no codes where JT lives
[16:54:47] <andypugh> (you could turn up the regulator, I suppose)
[16:54:51] <furrywolf> andypugh: they have a fitting at the hardware store that's pipe on one end, a shrader valve on the other, and has a gauge on top. you connect it to a pipe, pressurize it, pop your pressure source off the shrader valve, and watch the gauge.
[16:54:58] <Wolf_> regulators fail
[16:55:12] <furrywolf> schrader
[16:55:19] <Jymmm> furrywolf: Hey, I made one of those with garden hose fitting =)
[16:55:22] <Wolf_> same reason the water filter housings are rated to 110psi
[16:55:41] <furrywolf> http://www.bramec.com/cats/17255l.gif looks like that.
[16:55:59] <Sync> andypugh: they do it in germany
[16:56:23] <Jymmm> furrywolf: Thats what mine looks like bot 0-100 and garden female fiting =)
[16:56:26] <andypugh> That’s a job for a Chimney Sweep in Germany isn’t it?
[16:56:27] <Jymmm> but*
[16:57:07] <Jymmm> furrywolf: Found 4 water leaks at 60psi too =)
[16:57:48] <furrywolf> Jymmm: I had a water fitting develop a pinhole in it a few months ago... crappy sandy casting. fitting had been installed about a month. fucking china.
[16:57:49] <Sync> nope andypugh
[16:58:00] <Jymmm> furrywolf: ouch =(
[16:58:01] <Sync> only a gas water and shit installer can do it
[16:58:06] <andypugh> They just do the flues and CO tests then?
[16:58:10] <Sync> yes
[16:59:24] <Jymmm> furrywolf: I just had the whole house repiped, I asked if they pressure tested, they said no, so I did it instead, bastards.
[16:59:34] <andypugh> It’s interesting to me how in Germany a chimney sweep is a mandatory and regulated profession, and in the UK its just a guy who sweeps chimneys, and either the plumber or nobody is responsible for where the combustion products go,
[16:59:52] <Sync> interesting
[17:00:21] <furrywolf> pressure tested and found four leaks large enough to visibly leak water? I would have been rather unhappy with them.
[17:00:22] <Jymmm> andypugh: welcome to the "It's not MY job"
[17:00:40] <andypugh> Mainly boilers are installed by plumbers. The same guy does the water, gas and flue.
[17:00:42] <furrywolf> and here chimney sweeping isn't a specialized profession.
[17:00:43] <Jymmm> furrywolf: Eh, I called, they came and fixed it.
[17:00:54] <Jymmm> furrywolf: TWICE
[17:00:59] <Sync> well, it is a fire hazard andypugh
[17:01:11] <Sync> and I think people got fed up with chimney fires
[17:01:19] <andypugh> Yes, a sooty chimney is a danger, certainly.
[17:01:42] * Jymmm gets to be the chimney sweep next week
[17:01:48] <andypugh> But there is no mandatory inspection or sweeping schedule.
[17:01:57] <Jymmm> ...and not top hat either =(
[17:02:01] <Jymmm> no*
[17:02:15] <andypugh> Jymmm: Can you borrow a Victorian child?
[17:02:32] <XXCoder> make sure it can sing that song lol
[17:02:48] <furrywolf> amazingly I'm not finding googling what the maximum backpressure I can apply to a gas meter is.
[17:02:55] <Jymmm> andypugh: There are laws regarding child/slave labor, plus the whole actors guld thing wants licening /ryalty rights
[17:03:01] <Sync> interesting
[17:03:52] <andypugh> I used to think that Germans liked to have too many laws, and would always abide by them. Then VW happened…
[17:05:04] <andypugh> If I had to guess which company would be most likely to abide by the letter of the law it would be VW…
[17:05:30] <Sync> haha
[17:05:47] <Sync> every company tries to evade emissions
[17:05:56] <Sync> it has been that way and always will be
[17:06:27] <Jymmm> furrywolf: No worries, just plumb the gas line to the drain pipe in case of any leaks and hope someone isn't smoking on the toilet =)
[17:06:35] <andypugh> Interesting that in in the comparison drive where VW were 30x over stated emissions the BMW X5 was _under_ declared emissions. That’s actually rather impressive.
[17:06:59] <Wolf_> whats the mpg on each?
[17:07:03] <Wolf_> :P
[17:07:26] <andypugh> I don’t know. This was NOx
[17:07:40] <Sync> furrywolf: I think you are supposed to disconnect the meter
[17:08:08] <furrywolf> Sync: I think so too, but I really don't want to. heh.
[17:08:11] <andypugh> BMW spend a lot of money on aftertreatment. There is more margin on an X5 than a Golf, and more space for the parts too.
[17:08:24] <furrywolf> especially since the meter is their property, not yours, and you're not supposed to fuck with it...
[17:08:31] <Wolf_> worry about the NOx, who cares if it kills the efficiency down to nothing also
[17:08:56] <Wolf_> X5 probably gets half the mpg as a Golf as well
[17:09:01] <Sync> andypugh: I suppose every company spends about the same on it
[17:09:16] <JT-Shop> laser printer keeps saying the toner is low but it keeps printing...
[17:09:22] <andypugh> Sync: No, BMW spend more, their cars cost more.
[17:09:29] <Wolf_> lol
[17:09:30] <furrywolf> also, am I the only one disturbed by applying pressurized air to a system containing fuel gas, which will create an explosive mixture at some point during the filling? heh
[17:09:44] <Wolf_> if cars only worked that way...
[17:10:13] <andypugh> Sync: I work for a company that doesn’t even attempt to sell Diesel in the US. And it’s a US-based company.
[17:10:24] <Sync> furrywolf: plumbers will just remove live lines and then start to prep the plug for it
[17:10:27] <Sync> yeah I know
[17:10:35] <Sync> and I know that selling diesels in the US is a major pain
[17:11:29] <andypugh> furrywolf: No, that was my main concern with over-resssuring a live system. Thouugh I think that when you consider the actual volume of gas in the system the risk is tiny
[17:13:06] <furrywolf> I also want to blow the lines out with compressed air, to remove bugs/etc from the disconnected valves.
[17:14:12] <furrywolf> the one for the furnace pretty obviously has crap in it
[17:14:26] <Sync> also no real ignition sources inside the pipe
[17:14:58] <furrywolf> tweekers took all the copper and brass... so the main plumbing (steel) is intact, and the furnace valve (pot metal) is intact, but the shutoff valve (brass) and flex line (brass) are awol. because tweek.
[17:16:33] <Jymmm> furrywolf: Heh, all I can find is San Bruno crap
[17:16:33] <Wolf_> nice...
[17:18:55] <furrywolf> obvious statement is obvious: 6. A.4 The test medium for applying the air test can be air, nitrogen, or carbon dioxide.
[17:18:55] <furrywolf> OXYGEN SHALL NEVER BE USED!
[17:19:20] <Jymmm> furrywolf: HYDROGEN be a okey pankey!
[17:19:32] <Wolf_> pure oxygen does funny things sometimes
[17:19:41] <andypugh> furrywolf: Can you use FOOF?
[17:19:49] <furrywolf> lol
[17:19:54] <JT-Shop> how about using quick silver
[17:20:19] <furrywolf> no, it can be air, nitrogen, or carbon dioxide, like it says. :P
[17:20:35] <Jymmm> Yeah, the Almaden Quick Silver mine is just down the road from you furrywolf
[17:20:56] <andypugh> JT-Shop: Any liquid is functionally bad. In the case if Hg you might get a false-positive as the mercury amalgamated with the solder.
[17:21:58] <Jymmm> furrywolf: This is as close as I could find http://www.pge.com/includes/docs/pdfs/mybusiness/customerservice/startstop/newconstruction/greenbook/servicerequirements/02.pdf
[17:24:11] <Sync> andypugh: wasn't the problem with the us and diesel that they measure emissions in relation to gross vehicle weight or some crap?
[17:24:32] <andypugh> furrywolf: Have you read http://www.tor.com/2012/07/20/a-tall-tail/
[17:24:47] <andypugh> Sync: Everyone does.
[17:25:33] <Wolf_> emission standards in the usa for diesel are insane I have heard (big oil + car companies don’t want efficient cars)
[17:25:33] <furrywolf> andypugh: no
[17:25:35] <andypugh> The problem with the US and diesel is that they live in deserts with no wind.
[17:26:06] * furrywolf doesn't usually read fiction
[17:26:06] <andypugh> So NOx is seen as massively more important than CO2
[17:26:29] <andypugh> furrywolf: It’s short. And fun
[17:27:47] <andypugh> You have to love any story that makes a FOOF/dimethylmercury rocket motor seem like a sensible idea.
[17:28:35] <furrywolf> lol
[17:29:04] <furrywolf> have you read Ignition!? it also has implausible rocket fuels, but is entirely nonfictional.
[17:29:23] <andypugh> Not yet, it’son my list
[17:30:11] <furrywolf> http://web.gccaz.edu/~wkehowsk/ignition.pdf
[17:37:17] <Sync> huh, as I take it EURO regulates it with fixed values for each material andypugh
[17:39:04] <andypugh> Sync: No, you can actually produce an unlimited amount of CO2, though the vehicle will be in a higher tax band in places where they tax on CO2.
[17:40:13] <Sync> sure, as euro does not regulate CO2
[17:40:57] <Sync> I'm actually thinking of subjecting my race car to emissions testing
[17:41:02] <Sync> as it should have no problem passing
[17:41:14] <Sync> it is euro1 so pfft
[17:41:23] <furrywolf> you're probably not in california. :P
[17:41:35] <furrywolf> in here, the mere act of touching the emissions system makes it illegal.
[17:41:37] <furrywolf> because california.
[17:43:35] <furrywolf> bbl, plumbing. (of the water variety)
[17:44:30] <Sync> CARB tier 1 should be very easy to hit
[17:44:50] <zeeshan> i wish one of you guys was local
[17:44:55] <Tom_itx> why?
[17:44:55] * zeeshan would be sending machining jobs
[17:45:10] <Tom_itx> i wish i had a machine to do zeeshan's jobs
[17:45:25] <zeeshan> i dont have a single friend locally
[17:45:26] <Sync> shipping overseas is quick zeeshan
[17:45:28] <zeeshan> that is into machines like us
[17:45:40] <Tom_itx> glad you clarified that
[17:45:49] <furrywolf> do you have friends that are not into machines like us? :P
[17:45:56] <zeeshan> tons unfortunately
[17:46:08] <zeeshan> mostly car guys
[17:46:10] <Tom_itx> zeeshan you must be hangin with the wrong croud...
[17:46:11] <zeeshan> and engineers
[17:46:18] <furrywolf> so at least you're not entirely friendless. :P
[17:46:26] <zeeshan> that rather watch a movie than work in a shop
[17:46:26] <zeeshan> :{
[17:46:38] <furrywolf> bbl
[17:46:38] <zeeshan> i have one friend whos into working on machines
[17:46:42] <Sync> > car guy
[17:46:47] <zeeshan> but he's got the makerspace mentality
[17:46:49] <zeeshan> if you know what i mean..
[17:46:50] <Sync> > doesn't work in the shop
[17:47:06] <zeeshan> (you take apart something and never put it back together, you start a project -- never finish it)
[17:47:08] <Tom_itx> move?
[17:47:26] <zeeshan> (or build something completely useless like 3d print an anime character)
[17:47:37] <Tom_itx> or a turd?
[17:47:38] * zeeshan mumbles and grumbles to himself
[17:47:58] <zeeshan> that turd has brought enough money
[17:48:03] <zeeshan> to retrofit a lathe and buy a 3d printer
[17:48:05] <zeeshan> and do an atc swap
[17:48:09] <zeeshan> so don't make fun of the turd okay!
[17:48:17] <Tom_itx> mkay fair nuff...
[17:48:20] <Tom_itx> :)
[17:48:28] <zeeshan> i told my wifey
[17:48:33] <Tom_itx> but you've been griping about it
[17:48:34] <zeeshan> shop money buys shop stuff or car stuff
[17:48:48] <zeeshan> im just bitter
[17:48:53] <zeeshan> cause the guy always has something he wants to change
[17:48:55] <zeeshan> im sick of it
[17:48:56] <Tom_itx> better yet don't tell wifey what shop does at all
[17:48:58] <zeeshan> i told him off the other day
[17:49:07] <zeeshan> he wanted a curve changed
[17:49:08] <zeeshan> im like
[17:49:10] <Tom_itx> you know how to cure that?
[17:49:11] <zeeshan> "not going to happen"
[17:49:18] <zeeshan> "it's too late for that now"
[17:49:22] <Tom_itx> hit him with a nasty bill on hte next change order
[17:49:44] <Tom_itx> i ran into that once on a software job
[17:49:51] <Tom_itx> it actually works
[17:49:53] <zeeshan> hehe
[17:50:10] <zeeshan> also
[17:50:15] <andypugh> Not even a nasty bill. Just an actual hourly rate bill for all the time it takes.
[17:50:20] <zeeshan> im bitter cause he's given me oversize stuff
[17:50:27] <Tom_itx> they had no clue.. they found out what it could do... they wanted alot more for the same original agreement
[17:50:28] <zeeshan> so i need to remove a lot of extra stock for no reason.
[17:50:30] <Tom_itx> wrong answer
[17:50:32] <zeeshan> i gave him dimensions of wha ti wanted
[17:50:35] <zeeshan> and some stock he's given undersize
[17:50:40] <zeeshan> so there is a chance it won't completely machine right
[17:50:46] <zeeshan> that makes me really bitter.
[17:50:55] <zeeshan> just been venting here in different way, sorry :P
[17:50:59] <zeeshan> *ways
[17:51:09] * Tom_itx goes for icecream
[17:51:14] <zeeshan> haha
[17:51:56] <andypugh> zeeshan: It should only take a quick caliper check to reject undersize stuff?
[17:52:27] <zeeshan> andypugh: i wish it was like that
[17:52:35] <zeeshan> the stock is cut at random angles
[17:52:38] <andypugh> (Then charge him for creating the child-size version)
[17:52:40] <zeeshan> so i try my best to square it
[17:52:48] <zeeshan> and machine one side flat for my reference geomtry
[17:53:13] <zeeshan> so relative to the reference face
[17:53:16] <zeeshan> all surfaces have angles
[17:53:22] <zeeshan> its hard to tell if it'll be good or bad
[17:53:25] <zeeshan> i just know itll be close
[17:53:45] <zeeshan> http://i.imgur.com/ZU4JV8C.jpg
[17:53:47] <zeeshan> reference face
[17:53:54] <zeeshan> http://i.imgur.com/aUxi6fO.jpg
[17:53:57] <zeeshan> this pic it's hard to tell
[17:54:01] <zeeshan> but each one of them is at an angle
[17:54:01] <andypugh> In an ideal world you would throw it through a structured light grid and have a computer find the part in the stock :-)
[17:54:11] <zeeshan> haha
[17:55:05] <andypugh> Heh! Those look like that video I showed you on making expoxy-wood blanks
[17:56:00] <andypugh> Nice jig.
[17:56:01] <furrywolf> yay, an answer! 2. The gas meter and associated gas regulating equipment SHALL NOT be installed prior to any
[17:56:01] <furrywolf> pressure/leakage test. This equipment is to be leak tested at service line pressure.
[17:56:18] <PetefromTn_> hey folks
[17:56:34] <JT-Shop> hi
[17:56:47] <PetefromTn_> Hey JT
[17:57:01] <andypugh> I realised today that for my current job I should have made a 4-pin jig to allow me to rotate the part between jobs.
[17:57:13] <zeeshan> thanks :P
[17:57:22] <zeeshan> hi
[17:57:46] <andypugh> The parts need to be registered anyway.
[18:01:04] <andypugh> I have set up a config for the horizontal spindle, that means the mill can now do much larger workpieces. Interestingly it is also _much_ quieter.
[18:01:05] <andypugh> https://picasaweb.google.com/lh/photo/BRKHry0DJitoQMnrS9v5e9MTjNZETYmyPJy0liipFm0?feat=directlink
[18:02:11] <PetefromTn_> gotta motivate here and get my ass out to make that PVC bubbler for the anodizing tank LOL
[18:02:33] <PetefromTn_> but right now I am enjoying sitting and listening to Pandora ;)
[18:02:35] <Wolf_> yeahyou slacker
[18:02:43] <PetefromTn_> I am actually :D
[18:02:48] <andypugh> PetefromTn_: Can’t you use an aquairium part?
[18:02:58] <zeeshan> andypugh: ewwwwwwwwwwww mdf
[18:03:12] <PetefromTn_> I did mow the whole damn lawn, weed eat, spray weed killer, and and and
[18:03:17] <Wolf_> guess that means I should be making my stepper mounts right now lol
[18:03:18] <PetefromTn_> andypugh I dunno man
[18:03:22] <andypugh> Yes, I know. But I am making a foundry pattern
[18:03:44] <PetefromTn_> I bought a decent air regulator and a bag full of tees and elbow fittings etc.
[18:03:55] <PetefromTn_> oh and the glue can't forget the glue ;)
[18:04:07] <zeeshan> nice mill btw
[18:04:10] <zeeshan> what taper is the spindle?
[18:04:23] <PetefromTn_> Went to look at a sorta beat up Pontiac Fiero GT today..
[18:04:39] <JT-Shop> I feel your pain PetefromTn_ I need to finish siding the shop and garage, stack 750 retaining wall blocks and a zillion other things
[18:04:39] <PetefromTn_> depresses me to see them all neglected
[18:04:45] <andypugh> zeeshan: In the background is the lump pf pre-used model board (PU) that I wanted to use, but it is nowhere near big enough.
[18:05:22] <PetefromTn_> My wife suggested I get a bunch of 7/16 OSB board and sheet the walls of my shop so I can add shelves etc.
[18:05:24] <andypugh> zeeshan: 30 taper.
[18:05:50] * Wolf_ isn’t going to post his to-do list…
[18:06:17] <Wolf_> lets say for starters I have 20 square of siding sitting in my yard...
[18:06:38] <PetefromTn_> I resided my whole house and shop a couple years ago.
[18:06:42] <PetefromTn_> glad that shit is over
[18:07:03] <PetefromTn_> I had to remove that crappy masonite board and the old foam board
[18:07:30] <PetefromTn_> then put the 7/16 OSB, then new foam board, then the tyvek house wrap, then the new siding
[18:07:34] <PetefromTn_> took FOREVER
[18:07:37] <Wolf_> lol, mine is alum siding over wood lap siding, over a board and batt house
[18:07:55] <PetefromTn_> ya know what pisses me off
[18:08:04] <PetefromTn_> siding companies here will come to your house
[18:08:10] <PetefromTn_> and no matter how shitty the old siding is
[18:08:17] <andypugh> zeeshan: The horizontal is the origingal ISO 30. The vertical has a pnuematic drawbar, and became BT30. Then I got a deal on all that SK30 tooling in the photo (£80) and so converted the vertical to SK30 by shortening one dog.
[18:08:21] <Wolf_> which some dumb ass added a window to and cut out one of the king beams
[18:08:24] <PetefromTn_> they will just pop a few nails in and side right over that shit
[18:08:56] <PetefromTn_> I had a guy come here to quote me the work when I first started looking at getting it done
[18:09:04] <PetefromTn_> I was like SERIOUSLY>
[18:09:15] <PetefromTn_> you are just gonna go right over the masonite horizontal boards?
[18:09:22] <PetefromTn_> he's like sure man we do it all the time...
[18:09:31] <Wolf_> I won’t let any contractors touch my shit
[18:09:34] <PetefromTn_> Needless to say our conversation was over after that
[18:10:11] <andypugh> You giys need to make houses from durable material. My folks’ house hasn’t needed any attention to the “siding” in 500 years :-)
[18:10:38] <Wolf_> my house is only 200yrs old
[18:10:56] <zeeshan> andypugh: yea same here :P
[18:10:59] <zeeshan> mine was sk40
[18:11:02] <zeeshan> went to cat40
[18:11:10] <zeeshan> sk40 tooling is hard to find here
[18:11:19] <PetefromTn_> in retrospect it would probably be easier to build new house LOL
[18:11:33] <Wolf_> but new siding I got is concrete board so I shouldn’t have to mess with it
[18:12:00] <andypugh> I just got a deal because eBay folk didn’t realise that SK is only slightly different.
[18:12:02] <PetefromTn_> jeez man my house is only like 20 years old and I think it is OLD
[18:12:02] <JT-Shop> I'd hate to build my house and garage and shop over again... I'm too old for that shit anymore
[18:12:36] <andypugh> (the other way is harder, fitting BT / ISO / CAT to SK spindles is more tricksy
[18:13:57] <andypugh> Horizontal milling is great except you really can’t see what you are doing.
[18:14:27] <Wolf_> ok, seeing I don’t know anything about VFD stuff, what type of motor should I be looking for on ebay, something around 1/2-3/4hp...
[18:14:29] <andypugh> That already cost me that extra-long 10mm 2-flute in the photo
[18:15:17] <Wolf_> andypugh: add some cheap car backup cameras to the machine
[18:15:18] <andypugh> Wolf_: Ideally look for “Inverter Rated” in the description
[18:15:46] <andypugh> Anyway, sleepy-time
[18:18:17] <JT-Shop> say goodnight Gracie
[18:18:37] <PetefromTn_> Gn8 JT
[18:18:54] * JT-Shop has higher hopes for this pos microatx case now that I stole the power supply from the d525 case
[18:19:50] <JT-Shop> except I don't see where the hard drive goes???
[18:24:35] <Tom_itx> PetefromTn_, what about something like this only larger? http://tom-itx.no-ip.biz:81/~webpage/etching/newtank2.jpg
[18:24:51] <Tom_itx> perforated fish tank tubing
[18:25:12] <PetefromTn_> wth?
[18:25:17] <PetefromTn_> Oh okay
[18:25:35] <PetefromTn_> yeah that would have been useful BEFORE I bought all the PVC stuff LOL
[18:25:38] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/etching/etch4.jpg
[18:25:42] <Tom_itx> make more sense now?
[18:26:49] <Tom_itx> PetefromTn_, did you see my last tapping video?
[18:27:16] <PetefromTn_> no been busy with SCHTUFF
[18:27:28] <Tom_itx> https://www.youtube.com/watch?v=g99lUtjLfMU&feature=youtu.be
[18:29:37] <PetefromTn_> Sweet....Never seen a machine tap quite like that.
[18:29:48] <PetefromTn_> how is it that it can stop at the bottom?
[18:30:07] <PetefromTn_> also you got balls to rigid tap with a drill chuck LOL
[18:30:30] <Tom_itx> it was tight
[18:31:09] * Wolf_ gains hope for his POS mini mill
[18:31:27] <Tom_itx> it takes a bit for the PID to ramp up enough for the spindle to move. it's what you get with a small motor on a small machine
[18:32:09] <Tom_itx> without PID i doubt it would have worked
[18:32:44] <surgy> hi :)
[18:33:42] <PetefromTn_> pretty sweet tho
[18:33:47] <surgy> i hada few questions aboutlinuxcncif anyone is around to answer them
[18:34:18] <Wolf_> hmm, do 110 in 3phase out VFD exist?
[18:34:25] <Tom_itx> PetefromTn_, andy pointed out it was a good example because the axis still follows the spindle
[18:34:51] <PetefromTn_> Oh yeah it is cool to see LinuxCNC coordinated movement
[18:35:15] <PetefromTn_> can't do that shit with MACH3 LOL
[18:35:22] <Tom_itx> it's a machine i can play with linuxcnc on but i don't expect alot from it
[18:36:42] <Wolf_> or should i just deal with adding 220 to my hobby room lol
[18:37:52] <Tom_itx> PetefromTn_, that bubbler tank worked good for PCBs
[18:38:11] <Tom_itx> and all i used was a fishtank pump
[18:38:18] <Tom_itx> dual
[18:38:43] <surgy> so im currently building a cnc. i was looking into grbl and an arduino. but someone over at #electronics sugegsted i should take a serious look at linux cnc. will i be able to interface with my arduino to control my motor controllers...... or do you guys use a different system?
[18:39:06] <Tom_itx> we use linuxcnc
[18:39:09] <Tom_itx> run on a pc
[18:39:28] <surgy> Wolf_: chances are you dont have 3 phase power in your house at all......
[18:39:29] <Tom_itx> alot more versatile than any ardweenie could be
[18:39:39] <JT-Shop> lol
[18:39:52] <surgy> Tom_itx: yeah but how do you interface with the motors on the cnc machine?
[18:40:09] <Wolf_> surgy: umm duh, VFD inverter takes single phase in and puts out 3
[18:40:17] <Tom_itx> well you can use your motor drivers interfaced thru a parallel port or get a mesa card and use that
[18:40:34] <Tom_itx> the mesa solution is better because you get faster step rates etc
[18:40:58] <Tom_itx> they have various pc interfaces for them like parallel port, pci, pcie, ethernet
[18:41:00] <Tom_itx> spi
[18:41:06] <Tom_itx> for a few
[18:41:37] <Tom_itx> depending on you needs there is likely a mesa board to meet them
[18:42:20] <Tom_itx> and alot more IO than you get on a parallel port
[18:43:23] <Wolf_> Tom_itx: what motor/control setup are you running on that mill?
[18:43:33] <surgy> well i only need 8 io pins using an arduino..... i dont know about the serial port method yet or even how that works...... does linux cnc handle all of that? or do i have to write some software to tell it which pin is which?
[18:43:39] <Wolf_> for the spindle
[18:43:57] <Tom_itx> i'm using the stock sherline motor driver with some magic attached
[18:44:05] <Wolf_> lol
[18:44:10] <Wolf_> ok
[18:44:36] <Tom_itx> i added reversing relays and had to use an isolation board since their driver board floats GND
[18:48:09] <Wolf_> so http://www.ebay.com/itm/181855973794 + http://www.ebay.com/itm/220V-VARIABLE-FREQUENCY-DRIVE-INVERTER-VFD-1-5KW-2HP-7A-/180855426000 …is it that simple?
[18:51:06] <Tom_itx> for what mill?
[18:51:18] <Wolf_> x2 w/ R8
[18:51:35] <Tom_itx> i've not used a vfd so i dunno
[18:51:51] <Tom_itx> if i were gonna get one, i'd likely get a matched pair
[18:52:04] <Tom_itx> since i'm not that familiar with them
[18:52:20] <Wolf_> all I can find is spindle motors for routers
[18:52:27] <Wolf_> for matched sets
[18:52:36] <Tom_itx> yeah
[18:52:52] <Tom_itx> that or maybe a good servo :)
[18:55:23] <Wolf_> sewing machine servo motor? lol
[18:58:24] * JT-Shop made the pos case work for the gigabyte so it's time to call it a day
[18:58:42] <Wolf_> hmm http://www.ebay.com/itm/Industrial-Sewing-Machine-Servo-Motor-Brushless-750W-110V-/221896625867?hash=item33aa11cecb
[19:02:38] <kengu> mm..
[19:05:08] <Tom_itx> that motor doesn't look that big but i dunno
[19:07:04] <Wolf_> nema42 frame
[19:07:35] <Wolf_> wonder if the controls are hackable :D
[19:09:07] <Tom_itx> https://www.youtube.com/watch?v=1aNy9pgkyF0
[19:09:58] <Tom_itx> http://www.glockcnc.com/#!/Sherline-Spindle-Motors-Upgrade/c/8597972/offset=0&sort=normal
[19:13:10] <Wolf_> yup, I think dude is selling sewing machine motors for 4x the original cost lol
[19:14:06] <Tom_itx> could be
[19:15:50] <Tom_itx> i'd love to have a 1400w one on mine
[19:16:33] <Tom_itx> 800 would probably be enough
[19:16:38] <Tom_itx> but better than stock
[19:19:32] <Wolf_> http://www.ebay.com/itm/Enduro-Pro-SM600-Industrial-Sewing-Machine-Energy-Saving-Servo-Motor-/160668981972?var=&hash=item25689e1ad4
[19:19:48] <Wolf_> might give you a idea where to look :)
[19:22:01] <Tom_itx> the problem is those aren't gonna be tapped for external control
[19:22:11] <Tom_itx> step/direction etc
[19:22:26] <Wolf_> i’m looking now to see if someone has hacked one
[19:44:54] <MacGalempsy> HELLO
[19:44:59] <MacGalempsy> opps hello
[19:47:28] <Tom_itx> hElLo
[19:48:19] <XXCoder> hhhhello
[19:48:29] <malcom2073> HeLlO
[19:48:35] <MacGalempsy> hows it going guys?
[19:48:57] <XXCoder> not much
[19:49:34] <MacGalempsy> just had to change the psu on my workstation...
[19:49:43] <MacGalempsy> atleast it was pretty acccessible
[19:51:53] <MacGalempsy> anyone making anything cool today?
[19:52:15] <Wolf_> I should be, instead I’m looking at sewing machine motors
[19:52:28] <Tom_itx> Wolf_, lemme know how that goes
[19:53:17] <Wolf_> I found some mention of hacking them for taig cnc in a yahoo group post from 2 years ago
[19:53:30] <XXCoder> need parallel interface to make cool stuff
[19:53:35] <MacGalempsy> nice.
[19:53:47] <MacGalempsy> Sounds like a thriftstore mission
[19:54:10] <XXCoder> nah
[19:54:14] <XXCoder> ordered online
[19:54:27] <Wolf_> mentions adding a 10k pot to replace the photo interrupter in the foot control and possibly doing a PWM to digital pot
[19:55:04] <Tom_itx> mesa makes one of those i believe
[19:55:12] <Wolf_> MacGalempsy: 750W brushless servo sewing machine motors
[19:55:30] <MacGalempsy> do they have controllers in there?
[19:56:23] <MacGalempsy> what do those motors cost?
[19:56:57] <Wolf_> http://www.ebay.com/itm/Energy-Saving-Brushless-Servo-Motor-for-industrial-Sewing-Machine-750W-/221889352283?var=&hash=item33a9a2d25b
[19:57:53] <MacGalempsy> that looks like a pretty good deal. do they have encoders built in?
[19:58:25] <MacGalempsy> 4000RPM!
[19:58:29] <MacGalempsy> on an axis?
[19:58:31] <Wolf_> no idea, info is slim
[19:58:44] <Wolf_> spindle drive lol
[19:59:03] <Wolf_> thats almost 1hp
[19:59:16] <MacGalempsy> excuse me sir, I need a machine that can rapid at 1000ipm
[19:59:56] <Tom_itx> they are out there
[20:02:21] <MacGalempsy> even 400 ipm sounds scarey
[20:02:39] <XXCoder> theres there is ones that can do 10k ipm rapids
[20:03:52] <renesis> ha, fuckin knock your ass out jogging
[20:04:56] <renesis> the 5x10 router i worked on for a bit had crazy fast rapids
[20:05:25] <renesis> i dont remember the number, other than it seemed like a mind blowing value despite the speed not seeming unsafe in person
[20:05:39] <renesis> machine is bigger so going thata fast seems reasonable
[20:06:24] <malcom2073> You can get really high speeds with rack and pinion drive systems
[20:07:04] <malcom2073> Though I have some ballscrew actuators that have a max speed of 700in/min
[20:07:17] <renesis> this thing was big giant gantry on little recirculating ball bearing rails
[20:07:53] <renesis> it was fast but the acceleration wasnt more than what youd expect, just had a long distance to get up to speed
[20:08:06] <malcom2073> Yeah that's the other thing he
[20:08:08] <malcom2073> heh
[20:08:50] <renesis> like im not sure it ever reached it max speed in shorter than full X rapids, always sounded like it was accelerating in G0
[20:09:37] <renesis> neat machine to program, sucks that the boss guy couldnt sell shit
[20:11:08] <Tom_itx> i would bet those machines are energy hogs too
[20:11:10] <renesis> they made folding tables for laundromats and dry cleaners, i guess theirs last too long and there just werent that many more customers that they hadnt sold to
[20:11:21] <malcom2073> Heh
[20:11:53] <renesis> i got there and there was a big backlog because no one to drive the machine, cleared the backlog, ask boss what now
[20:12:21] <renesis> 'can you fix my laptop keyboard?' 'yeah sure but really what no you have no more orders?'
[20:12:44] <renesis> and that was the end of that job =\
[20:14:59] <renesis> http://jbmillwork.com/Router1.jpg
[20:15:57] <renesis> ha they dont have the safety mat
[20:17:08] <renesis> first job was to disable sawdust fucked estop mat =\
[20:17:28] <XXCoder> what a huge head
[20:17:50] <malcom2073> Yeah that's an oddly large head, toolchanger inside?
[20:17:56] <renesis> it has shit for horizontal drilling, sometimes was pretty good at catching all its dust
[20:18:04] <XXCoder> nah tools a foot wide. ;)
[20:18:25] <renesis> the toolchanger is off to the side
[20:18:30] <XXCoder> malcom2073: I see toolchanger off to side so I guess no.
[20:18:32] <malcom2073> Ah I see the post
[20:18:33] <malcom2073> yeah
[20:18:52] <renesis> that head is like 80% empty
[20:19:22] <renesis> the headstock and multiple spindle assembly is big but its nowhere near the size of that housing
[20:19:32] <renesis> i think thats mostly to hang the curtain on
[20:21:52] <zeeshan> man these tensors are giving me a headache
[20:21:59] <zeeshan> visualizing them .. !
[20:22:12] <zeeshan> where is toastydeath
[20:22:12] <zeeshan> :P
[20:26:54] <XXCoder> heh
[20:30:12] <PetefromTn_> tensors?
[20:35:13] <MacGalempsy> anyone watching the Blood Moon Eclipse?
[20:35:22] <zeeshan> yes
[20:35:25] <PetefromTn_> is it happening now?
[20:35:31] <MacGalempsy> yeah
[20:37:22] <XXCoder> still sunny here
[20:37:54] <zeeshan> PetefromTn_: basically this: http://solidmechanics.org/text/Chapter3_2/Chapter3_2.htm
[20:37:54] <zeeshan> :P
[20:38:04] <zeeshan> im using them for one problem set
[20:38:07] <zeeshan> i havent done this stuff in 2 years
[20:38:15] <zeeshan> coming back to bite me
[20:38:18] <XXCoder> https://www.timeanddate.com/eclipse/in/usa/seattle
[20:38:26] <jdh> too cloudy here
[20:38:49] <MacGalempsy> http://www.timeanddate.com/eclipse/in/usa/fort-smith
[20:38:58] <MacGalempsy> we get the full eclipse here
[20:39:33] <MacGalempsy> XXCoder: sorry to see its still below the horizon
[20:39:45] <PetefromTn_> baah its overcast here now
[20:40:23] <zeeshan> MacGalempsy: thanks for reminding man!
[20:40:54] <MacGalempsy> no prob, we were talking about it in Google Hangout
[20:41:02] <PetefromTn_> can't see shit out there right now
[20:41:12] <XXCoder> PetefromTn_: heh I remember one day we had rare venus transit
[20:41:35] <XXCoder> it was overcast, buts JUUUST cleared up a little to be able to see it directly during transit
[20:41:40] <XXCoder> same for moon eclipse
[20:43:13] <PetefromTn_> I think the ONLY eclipse I ever actually personally saw was way back when I was in grade school they had a solar eclipse and we watched it using paper cups with pinholes in them reflected on paper plates
[20:43:51] <Wolf_> man, finding info on this shit sucks, http://store.allamericansewing.net/eagle-special-sc800fl-sewing-machine-servo-motor-with-needle-positioner-800-watt-1-hp says bi directional from digital input and electronic speed input, no info on how any of that works lol
[20:44:22] <XXCoder> PetefromTn_: you can go to store buy emergacy silvered blankets
[20:44:26] <XXCoder> make a google with it
[20:44:29] <XXCoder> works great
[20:45:38] <Tom_itx> i've seen several
[20:46:19] <XXCoder> https://dl.dropboxusercontent.com/u/53432577/CIMG1189.JPG
[20:46:26] <XXCoder> https://dl.dropboxusercontent.com/u/53432577/CIMG1186.JPG
[20:47:01] <XXCoder> its though clouds so it looks very foggy. and extreme darkness with sucky camera (epic 4g)
[20:47:03] <PetefromTn_> I have TRIED to watch several but like tonight whenever something cool in the sky happens it is always overcast where I am
[20:47:22] <Tom_itx> i bet it's clear sky in FLorida !
[20:47:34] <XXCoder> other picture is of silvered googles
[20:47:36] <XXCoder> and cheap cardboard ones
[20:47:38] <PetefromTn_> OF COURSE~~
[20:47:42] <XXCoder> as you can see, its 2 sheets each
[20:47:57] <PetefromTn_> I would just probably grab my welding hemmet ;)
[20:48:13] <Tom_itx> yep, i just use welding glass
[20:48:44] <XXCoder> the googles was IR googles I converted over to sun googles then converted back after done
[20:49:00] <Tom_itx> goggles
[20:49:07] <Tom_itx> googles is a search engine
[20:49:56] <XXCoder> yeah yeah common mnistake for me lol
[20:50:17] <Tom_itx> i speak irc typo..
[20:50:35] <Tom_itx> speel it quite fluently too
[20:51:05] <XXCoder> :)
[20:51:22] <PetefromTn_> http://imgur.com/n87gKAI OMG!!
[20:51:56] <XXCoder> .. is it dead?
[20:52:18] <Wolf_> one of the Stark family is gonna be pissed
[20:52:18] <PetefromTn_> well yeah
[20:52:27] <XXCoder> sad.
[20:52:43] <PetefromTn_> I thought my husky was big until I saw that monster
[20:52:44] <zeeshan> thats a huge wolf
[20:52:45] <zeeshan> holy shit
[20:52:52] <PetefromTn_> LOL I Know right
[20:53:01] <zeeshan> that one deserves to get shot!
[20:53:05] <PetefromTn_> imagine that thing stalking you in the camping woods
[20:53:08] <zeeshan> yea
[20:53:12] <zeeshan> that'd kill a human no prob.
[20:53:17] <zeeshan> doesnt even need to be in a pact
[20:53:27] <PetefromTn_> shit regular dogs can kill a human
[20:53:44] <PetefromTn_> that thing would make short work of you
[20:53:46] <zeeshan> pitbulls
[20:53:46] <zeeshan> :(
[21:01:17] <MacGalempsy> PetefromTn_: imagine all the ticks on that thing!
[21:01:26] <PetefromTn_> hehe
[21:01:39] <PetefromTn_> that is one damn huge canine tho
[21:13:10] <XXCoder> zeeshan: why do it DESERVE to get shot?
[21:13:30] <zeeshan> everything deserves to get shot
[21:13:51] <XXCoder> okay lemme get a gun and visit you for... lunch. yeah.
[21:13:57] <zeeshan> come
[21:14:11] <zeeshan> ill machine you into a vaporizer
[21:14:20] <XXCoder> honestly it is predators that encourage diversity in ecosystem
[21:14:32] <zeeshan> XXCoder: are you an expert at biology
[21:15:00] <XXCoder> I read recent research on washington state re-introduction of wolves.
[21:15:04] <XXCoder> wow so big changes
[21:15:27] <XXCoder> odd effects is rivers are better since theres less deers eating plants and encouraging erosion.
[21:16:03] <XXCoder> many amny other stuff. deer eat a LOT and other species have hard time getting something to eat. feel free to hunt deer when its in season and such
[21:16:49] <zeeshan> you read a paper
[21:16:51] <zeeshan> and youre an expert
[21:16:53] <zeeshan> :P
[21:17:47] <PetefromTn_> I have no problem with responsible legal hunting whatsoever
[21:17:49] <Wolf_> too many deer here, import wolves IMO
[21:18:01] <zeeshan> PetefromTn_: people don't even fucking know how the burger they're eating
[21:18:02] <zeeshan> is made
[21:18:07] <PetefromTn_> my grandfather was a big hunter
[21:18:14] <zeeshan> and they get all whiny
[21:18:18] <zeeshan> when they see something like the picture you showed
[21:18:27] <PetefromTn_> I still have the .308 he used to kill everything from deer to bear to you name it....
[21:18:29] <zeeshan> so im used to hearing comments like that
[21:18:50] <zeeshan> most people also don't understand how tags work
[21:18:51] <zeeshan> :P
[21:19:06] <PetefromTn_> I went with him when I was just a little kid to hunt deer in upstate new york
[21:19:12] <zeeshan> thats cool
[21:19:19] <PetefromTn_> all I remember was good times with him and freezing my ass off
[21:19:28] <zeeshan> i've never killed anything myself yet
[21:19:39] <PetefromTn_> seemed I was not a good luck charm for hunting with him LOL
[21:19:39] <zeeshan> but i have been with others doing it
[21:19:49] <PetefromTn_> everytime I went he did not get anything
[21:19:53] <zeeshan> haha
[21:20:00] <zeeshan> PetefromTn_: i was reading through the hunting manual
[21:20:08] <zeeshan> you can't hunt deer when they're in the water!
[21:20:11] <zeeshan> hunting
[21:20:22] <zeeshan> infact some guy got charged for killing a deer while it was bathing
[21:20:40] <zeeshan> i like how there are rules to give the animal a fair chance
[21:20:51] <PetefromTn_> I think I'd be scared shitless to hunt anything in Canada with huge freaking Grizzly bears all over the place
[21:20:57] <zeeshan> haha
[21:21:08] <zeeshan> dude i was in new foundland visiting my dad
[21:21:10] <PetefromTn_> and wolves like in that picture
[21:21:12] <zeeshan> we decided to go for a hike...
[21:21:25] <zeeshan> me and my friends came across a salmon lake.
[21:21:37] <zeeshan> there were tons of salmon just breeding and doing whatever
[21:21:42] <zeeshan> and we heard a grunt
[21:21:50] <zeeshan> further away in the woods
[21:22:00] <zeeshan> never found out what it was, but that scares the shit out of me
[21:22:03] <zeeshan> it sounded like a bear
[21:22:10] <zeeshan> we also saw claw marks on trees
[21:22:12] <PetefromTn_> I am sure it probably WAS a bear
[21:22:30] <zeeshan> https://upload.wikimedia.org/wikipedia/commons/0/09/Grizzly_claw_marks_on_a_tree_near_a_hair_snag_station_(Northern_Divide_Grizzly_Bear_Project)_(4428160760).jpg
[21:22:36] <zeeshan> we saw marks like that ocassionally on trees
[21:22:40] <PetefromTn_> he was probably thinking I bet that dude tastes like chicken!!
[21:22:44] <zeeshan> hahaha
[21:22:51] <zeeshan> or maybe he was pissed that i was looking at his salmon
[21:22:57] <PetefromTn_> or both
[21:23:02] <PetefromTn_> hehehe
[21:23:36] <zeeshan> how come you havent gone hunting yourself?
[21:23:46] <PetefromTn_> I can't imagine living and fishing where apex predators like that roam all around
[21:23:51] <PetefromTn_> Oh I have
[21:23:54] <XXCoder> zeeshan: I never claimed I was a expert
[21:24:02] <PetefromTn_> used to hunt squirrels with friends around here
[21:24:08] <PetefromTn_> dove
[21:24:09] <zeeshan> XXCoder: but what you're talking about really needs an experts opinion
[21:24:14] <PetefromTn_> mostly with airguns
[21:24:22] <zeeshan> even those guys have a hard tim explaining things.
[21:24:23] <XXCoder> zeeshan: well thats what I read
[21:24:31] <zeeshan> so it's not as cut clear as you're describing
[21:24:42] <PetefromTn_> I would REALLY like to hunt a bigass wild turkey with a precision airgun
[21:24:51] <PetefromTn_> but it is illegal in our state so far
[21:25:07] <zeeshan> you cant hunt turkey?1
[21:25:19] <PetefromTn_> no you can just not with an airgun
[21:25:30] <XXCoder> zeeshan: actually research was VERY clear
[21:25:34] <PetefromTn_> there are some states where that is legal with certain calibers of airguns
[21:25:52] <XXCoder> vareity of life in region rose suddenly and much more vareity
[21:26:00] <XXCoder> and rivers improved in quality
[21:26:53] <PetefromTn_> Oh I had a DELICIOUS burger today at a local Bar/Grill
[21:27:03] <PetefromTn_> it was called a voodoo burger
[21:28:35] <PetefromTn_> cajun spices and some sort of creamy cheese that I cannot recall the name of
[21:28:40] <PetefromTn_> started with a B
[21:28:48] <PetefromTn_> brougel or something like that
[21:28:55] <PetefromTn_> DAMN was it good
[21:30:08] <zeeshan> XXCoder: cool story
[21:30:14] <XXCoder> "story"
[21:30:20] <zeeshan> 1 ecosystem
[21:30:23] <zeeshan> must be the same as the other !
[21:31:41] <zeeshan> XXCoder: i am just in an argumentative mood :P
[21:31:43] <zeeshan> sorry
[21:31:57] <XXCoder> np
[21:32:12] <XXCoder> it's just that most ecosystems DO need predators
[21:32:23] <zeeshan> logic says you need a balance
[21:32:26] <zeeshan> don't overhunt
[21:32:30] <zeeshan> don't overpopulate
[21:32:53] <XXCoder> exactly, and hunting predators is not good. better hunt animals currently overpopulating area
[21:32:56] <zeeshan> every species has a purpose
[21:32:57] <XXCoder> as deer or elk tend to.
[21:32:59] <zeeshan> except prolly humans :p
[21:33:07] <zeeshan> actually we got a purpose too
[21:33:13] <zeeshan> how to screw everything :)
[21:33:20] <XXCoder> nah purpose is where we have to come up with. we don't automically get one.
[21:33:35] <zeeshan> hunting predators is perfectly fine
[21:33:38] <zeeshan> when they're eating your people
[21:33:44] <zeeshan> without the massive wolf hunts of the 1800s
[21:33:55] <zeeshan> you and me had a high chance of dieing just walking .
[21:34:27] <SpeedEvil> I am reminded of the australian governments recent action against shark attacks (which are basically not a threat)
[21:34:29] <XXCoder> yeah then deers and elks broke ecosystem
[21:34:32] <XXCoder> we should have left some
[21:34:46] <SpeedEvil> http://www.independent.co.uk/arts-entertainment/photography/selfies-are-killing-more-people-than-shark-attacks-10512449.html
[21:34:59] <XXCoder> SpeedEvil: yeah laughed when I read that
[21:36:43] <PetefromTn_> hey cool I can see the damn blood moon!!
[21:36:51] <XXCoder> lemme see
[21:37:43] <PetefromTn_> how?
[21:37:52] <justanotheruser> PetefromTn_: take a picture and link it
[21:37:57] <justanotheruser> I'm afraid to go outside
[21:38:01] <PetefromTn_> I have been trying to
[21:38:14] <PetefromTn_> but my cellphone is only so so and my digital camera is on the fritz
[21:38:17] <PetefromTn_> ;)

[21:42:57] <XXCoder> aww
[21:43:05] <XXCoder> still below horzon
[21:47:18] <PetefromTn_> well I just went back outside trying to get a picture
[21:47:55] <PetefromTn_> the clouds have come back in a bit and it seems like the eclipse is in full effect so it is quite dark looking
[21:49:54] <Tom_itx> too light here to get anything that resembles a picture

[21:51:52] <[cube]> any idea what that system might be worth?
[21:52:20] <[cube]> small panel, probably around 250w, inverter
[21:52:33] <[cube]> battery is likely shot
[21:52:49] <[cube]> its all around 10yrs old i beleive
[21:53:03] <XXCoder> not too much now
[21:53:11] <XXCoder> not sure exact number though
[21:53:29] <[cube]> guy wants $75 for it
[21:53:41] <zeeshan> for those of you
[21:53:43] <zeeshan> with cloud cover
[21:53:44] <zeeshan> http://www.timeanddate.com/eclipse/in/canada/hamilton
[21:53:46] <zeeshan> :D
[21:53:51] <zeeshan> find your own city
[21:53:58] <[cube]> sup zeeshan
[21:54:00] <zeeshan> hi cube
[21:54:01] <zeeshan> :P
[21:54:04] <[cube]> that link is broke!
[21:54:12] <zeeshan> ;[
[21:55:41] <[cube]> there it goes
[21:56:49] <XXCoder> https://www.timeanddate.com/eclipse/in/usa/tacoma
[21:57:40] <zeeshan> yay
[21:57:45] <zeeshan> clear sky now!!!!1
[21:57:52] <zeeshan> i can see the orangey moon
[21:58:41] <XXCoder> maybe will see later stages but probably not full moon
[22:00:29] <PetefromTn_> just went back out there....cant see shit now
[22:04:37] <zeeshan> pete have you tried drag knife engraving?
[22:05:58] <PetefromTn_> nope don't have a drag knife
[23:37:08] <Contract_Pilot> Almost had a byte on a Mesa card but found out there were 7I77 not 76's
[23:38:15] <Wolf_> so, 7x lathe/X2 spindle, taper bearings?
[23:38:32] <Contract_Pilot> Darn it would have lonve to get rid of these. http://www.stevenrhine.com/wp-content/uploads/2015/09/AFCO-300x169.jpg
[23:39:16] <Contract_Pilot> I think they are Roller Taper in the X2 they may just be general purpose also;.
[23:39:32] <Contract_Pilot> My friend put in AC bearing's in his.
[23:39:52] <Contract_Pilot> 3phase AC servo for spindle 6,000 RPM hahaha
[23:40:39] <Wolf_> yeah, I’m looking at brushless 1hp sewing machine servo motor for the x2 head, working out my parts list
[23:41:55] <Wolf_> least if that idea doesn’t pan out for cnc spindle control I can shove the motor setup on the C2 lathe lol
[23:46:43] <Wolf_> I’m going to be building the head from parts so I get to pick whatever bearings I want :)
[23:50:33] <MacGalempsy> anyone familiar with how to tell which writer is setting a signal?
[23:50:55] <MacGalempsy> im trying to enable the spindle through HALCMD, but it isnt working
[23:54:29] <Wolf_> use the autoconfig to make a test setup and assign the pin right?
[23:55:35] <Wolf_> then use the test setup to figure out what needs to be changed in the current config, least thats how I have been doing stuff
