[01:19:30] <zeeshan|2> XXCoder: must be 3156
[01:19:34] <zeeshan|2> that is a standard bulb size
[01:19:37] <zeeshan|2> never heard of3475!
[01:51:57] <Jymmm> Know where to get an 80CF (36" tall) Nitrogen tank cheap?
[02:20:12] <Deejay> moin
[03:23:54] <Tom_itx> 5°F
[03:24:37] * Jymmm hands Tom_itx a lump of coal
[03:25:11] <Jymmm> Tom_itx: you up late
[03:30:44] <archivist> syyl, I saw your pictures, nice, mines is 6mm collet size too, I got a lathe and added cardboard box which make up to more than one http://www.collection.archivist.info/searchv13.php?searchstr=lorch+watch
[04:00:49] <The_Ball> Is there a good way to get more debugging info out of LinuxCNC? I've turned DEBUG= 7FFFFFF on but there still isn't much output about the joint following error
[04:01:10] <The_Ball> mec/task/taskintf.cc 617: Error on axis 0, command number 113
[06:48:25] <CaptHindsight> -9F (-23C) warmer than yesterday
[07:16:14] <witnit> the_ball Im not sure how to get more debug, but have you seen this? https://groups.google.com/forum/#!topic/machinekit/N_mhihZyEJ8
[07:19:39] <witnit_> my first guess woud be to increase ferror and see if it persists
[07:47:35] <XXCoder> zeeshan|2: yeah no idea why its listed as 3475 but reserach says yeah 2156
[07:47:46] <XXCoder> http://www.thetruckstop.us/forum/threads/how-to-35w-pin-mod-for-single-use-3157-bulbs.4446/
[07:48:01] <XXCoder> strange hack to use 3157 as "extra bright light"
[08:00:03] <Tom_itx> 8°F warming trend.
[08:00:34] * Deejay requests also -20 C
[08:09:22] <SpeedEvil> XXCoder: lol
[08:12:43] <_methods> global warming in action
[08:22:10] <JT-Shop> 6F here, glad to see the shop at 50F
[08:24:52] <_methods> we couldn't get 2 of our rotary screws to run this morning lol
[08:25:09] <_methods> they're on cold strike
[08:25:56] * JT-Shop thinks he will burn several sticks of wood today
[08:42:31] <_methods> it's so funny they started school 3 hours late today because it's cold
[08:42:33] <_methods> heheh
[08:43:00] <_methods> cold delay
[08:43:27] <malcom2073> They used to do that when I was in school, cause our heaters sucked, and they refused to run them overnight
[08:43:57] <tjtr33> Tom_itx, the pressure front moved int Chicago near 6:30 am. broke out the pseudofed to relive the brain squeeze.
[08:52:37] <ssi> hey it's the tropics where I am
[08:52:38] <ssi> 10F
[10:37:54] <zeeshan|2> brrrrr
[10:45:08] <tjtr33> if temperature in Fahrenheit was probability, then we'll reach normality near 3pm CDT ( -3 F and counting now )
[11:10:51] <zeeshan|2> i have tacho wires going through a cable gland
[11:11:01] <zeeshan|2> but they need to be pined into a molex connector
[11:11:14] <zeeshan|2> which is already pinned to some other wires. so later on when i want to remove the tacho wires, it'll have to cut them if i leave it as is
[11:11:28] <zeeshan|2> anyone got a suggest for a harness connector for 2x 18 awg wires
[11:11:32] <zeeshan|2> something not bulky
[11:12:07] <malcom2073> yes
[11:12:08] <malcom2073> I do
[11:12:09] <malcom2073> um
[11:12:18] <malcom2073> Drawing a total blank on their name, they're like $6 each
[11:12:25] <malcom2073> deutch!
[11:12:49] <malcom2073> let me find a link
[11:12:54] <moorbo> deutch?
[11:13:19] <malcom2073> Deutsch ATP
[11:13:32] <malcom2073> http://www.waytekwire.com/products/24/Deutsch-DTP-Compatible-ATP-Connectors/
[11:13:40] <malcom2073> Waterproof, as a bonus
[11:13:59] <malcom2073> Not*terribly* bluky, but not terribly thin either
[11:20:29] <jdh> what's a harness connector?
[11:21:15] <zeeshan|2> what malcom posted
[11:21:25] <zeeshan|2> bottom right one
[11:24:27] <jdh> I have a bunch of Anderson PowerPole(tm) connectors
[11:25:49] <jdh> http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/15-amp-red-black-anderson-powerpole-sets.html
[11:43:20] <tjtr33> zeeshan|2, just use standard shrouded crimp on spades. use a male & a female on one side, and mates on other.
[11:43:21] <tjtr33> you wont inverts the tacho polarity. its cheap, a few cents
[11:44:51] <tjtr33> like these http://www.ebay.co.uk/itm/Pack-of-25-Blue-Shrouded-Crimp-On-6-3mm-Female-Spade-Terminals-Connectors-/321215651507
[11:45:14] <jdh> you can stagger them also so they are thinner. I use the bullet shaped ones though.
[11:46:27] <zeeshan|2> okay good idea
[11:46:52] <zeeshan|2> tjtr33: what do you mean mates?
[11:48:31] <tjtr33> male to female, female to male mates as in the bible ;)
[11:48:38] <zeeshan|2> ah okay
[11:48:39] <zeeshan|2> hahah
[12:19:25] <jdh> in some states (and .ca) you can mate teh other way.
[12:25:55] <tjtr33> what would woody guthrie say about these single sex unions? " i dunno why we'd keep the girls out of the union! sounds kinda fascist ta me" http://en.wikipedia.org/wiki/File:Woody_Guthrie_2.jpg
[12:27:03] <cradek> woodie was on the front lines fighting for racial equality, and I have no doubts he'd be writing songs about the people fighting for their equality today too.
[12:27:13] <cradek> woody
[12:29:36] <tjtr33> "union maid" woody
[12:45:49] <Tom_itx> why do i keep reading tacho as taco?
[12:46:04] <Tom_itx> quite confusing
[12:51:21] <pcw_home> lunchtime?
[12:51:38] <Tom_itx> pretty close
[12:52:57] <Tom_itx> pcw_home, does the driver detect what interface is plugged in on the 7I90? I didn't see any jumpers for that
[13:10:33] <pcw_home> No 7I90 behavior is determined only by bitfile (except serial modes have some options set on the HDR26 connector pins)
[13:29:41] <Tom_itx> i meant parport vs SPI or serial
[13:31:22] <pcw_home> No, the 7I90 configuration determines what interface it uses
[13:33:42] <zeeshan|2> any other safety checks to do
[13:33:51] <zeeshan|2> other than measuring resistance between live terminals and case ground
[13:34:15] <Tom_itx> you check that with the power off don't you?
[13:34:21] <zeeshan|2> yea
[13:34:27] <zeeshan|2> by live terminals i mean l1 and l2
[13:34:36] <zeeshan|2> not w/ power attached to em
[13:34:51] <zeeshan|2> i dont have a megger insulation rester
[13:34:57] <zeeshan|2> *tester, so i cant check insulation.. but it should be good!
[13:35:12] <zeeshan|2> any other quick and easy tests? =]
[13:35:24] <archivist> ground continuity
[13:35:39] <zeeshan|2> betweeen ground bar in cnc panel
[13:35:43] <zeeshan|2> and mains earth?
[13:36:36] <archivist> and case
[13:37:36] <archivist> then any safety issue will blow a fuse/ earth leakage breaker and you dont get hurt
[13:38:05] <Tom_itx> i'm tempted to put a GFIC outlet on mine
[13:38:11] <zeeshan|2> i cant with vfds
[13:38:14] <zeeshan|2> too much leakage current
[13:38:30] <zeeshan|2> i think youd need to bump the breaker to trip at 30mA
[13:41:46] <zeeshan|2> i wonder if they have a gfci 100 amp breaker
[13:42:58] <zeeshan|2> nope :/ not for residential panel
[13:43:01] <zeeshan|2> at least by siemens
[13:43:05] <zeeshan|2> biggest i see is 60A
[14:04:22] <jdh> http://amzn.com/B00OK091OW
[14:05:40] <tjtr33> i like the craftsman style mortise & tendon
[14:05:56] <tjtr33> tenon
[14:15:25] <malcom2073> Heh wow
[14:44:57] <JT-Shop> this Hertel parting tool is nice
[14:47:39] <JT-Shop> I just need some of those high dollar inserts to show up
[14:48:16] <JT-Shop> https://www.mscdirect.com/product/details/93651024?rItem=93651024
[14:48:26] <JT-Shop> I bet the insert don't fall out of this one
[15:03:54] <_methods> i like the replaceable bottom blade on that
[15:04:14] <_methods> those things get killed easy and you end up having to throw the whole tool holder away
[15:05:00] <JT-Shop> yea, both top and bottom parts are only about $20 each
[15:05:03] <_methods> parting always seems go go wrong
[15:05:11] <_methods> parting and tapping
[15:05:37] <_methods> i just use those indexable parting blades anymore
[15:05:40] <JT-Shop> this one fits my tool holder without modification and cuts to the max size of the lathe collet 1.625"
[15:05:47] <JT-Shop> so it is good
[15:07:05] <_methods> http://www.mscdirect.com/product/details/60821188?CS_010=60821188&item=60821188&CS_003=7867724&src=pla&cid=PLA-Google-PLA+-+Test
[15:07:08] <_methods> like that guy
[15:25:01] <JT-Shop> I break them too easy and then it's $110 in the trash
[15:25:32] <_methods> i think we get them for like $40
[15:25:54] <_methods> hell i havne't looked an invoice in awhile though
[15:26:13] <_methods> i hope they aren't $120 like that iscar one
[15:26:25] <JT-Shop> I'm thinking the clamp type will hold the insert better for my abuse
[15:26:30] <_methods> yeah
[15:26:54] <JT-Shop> I don't have a bar feed so I use the parting tool to index the material
[15:27:10] <_methods> ah that's your push stop
[15:39:57] * Tom_itx wonders if JT-Shop knows what a parting tool is made for :D
[15:40:51] <Tom_itx> i bet you've been doing it that way for years
[15:42:05] <zeeshan|2> JT-Shop: how do you lock the chuck
[15:44:46] <furrywolf_> what about a separate stop of some kind mounted on the backside of the table?
[15:55:51] <furrywolf_> http://images.craigslist.org/00o0o_8aezR4tpIWc_600x450.jpg never seen one of those before... what the heck is that used for?
[15:58:25] <malcom2073> Hmm... goes inside some kind of pipe?
[15:58:36] <malcom2073> With a ratcheting mechanism so you can't go in reverse?
[15:59:15] <furrywolf_> it looks like a milling cutter to me, but it'd sure make an odd shape...
[15:59:36] <furrywolf_> http://medford.craigslist.org/tls/4833090735.html
[16:05:30] <Tom_itx> zeeshan|2 what sort of resistance did you get on your mains test?
[16:05:53] <zeeshan|2> i dont have the ground hooked up yet to the box from the main panel
[16:05:57] <zeeshan|2> still looking for thhn :/
[16:06:00] <zeeshan|2> its really expensive
[16:08:04] <Tom_itx> i'm getting 85 ohms across Hot & Neutral with the breakers off
[16:08:23] <Tom_itx> i'm not sure what could be plugged into that circuit though
[16:08:27] <zeeshan|2> why are you measuring between hot and neutral?
[16:08:34] <Tom_itx> i wanted to see
[16:08:36] <Tom_itx> :)
[16:08:46] <furrywolf_> measure voltage now
[16:08:50] <zeeshan|2> did you check hot to case?
[16:08:51] <Tom_itx> 123v
[16:08:58] <furrywolf_> could just be picking up enough noise to confuse your ohms scale.
[16:09:06] <Tom_itx> i'm not at the control. i'm checking wiring to it first
[16:09:22] <furrywolf_> no, I mean measure voltage with the breaker off. :)
[16:09:40] <Tom_itx> i get around .5 to .9 across neutral to GND on all the other tests i did
[16:09:54] <Tom_itx> furrywolf_, it was 0
[16:10:02] <Tom_itx> i did :)
[16:10:07] <furrywolf_> lol
[16:11:42] <Tom_itx> i get about 1 to 1.1 drop on the power cord on each leg
[16:12:07] <Tom_itx> i wouldn't think it would be that much
[16:14:40] <furrywolf> so any idea what that cutter is for? heh
[16:15:46] <Tom_itx> the insert is a roughing insert
[16:17:10] <Tom_itx> the tool is a small shell mill
[16:17:48] <furrywolf> so it's just roughing inserts, not some weird gear machining instead of hobbing cutter or something else that I was trying to figure out. heh.
[16:18:05] <Tom_itx> that was my best guess
[16:18:12] <furrywolf> I've never seen a cutter with fully round inserts like that... only square or triangular...
[16:18:26] <Tom_itx> they make round inserts
[16:19:28] <Tom_itx> the insert may be something else though
[16:19:40] <Tom_itx> http://shopmetaltech.com/products/round-insert-for-heavy-duty-roughing.html
[16:20:03] <furrywolf> I was trying to figure out if it was for making gear teeth, maybe for machining internal threads on a large-diameter part,...
[16:20:35] <Tom_itx> they look too rounded for gear cutting
[16:21:08] <furrywolf> see, the one you pasted LOOKS like a generic cutter, not some special profile...
[16:21:57] <Tom_itx> they may be for something special
[16:22:13] <Tom_itx> i don't see how they could index them to each other to cut gears or other profiles
[16:23:06] <furrywolf> the clamp looks like it's designed to index the wheels... the other ones I'm finding for round inserts just have the middle screw...
[16:23:26] <Tom_itx> i dunno
[16:23:31] <Tom_itx> i have my doubts
[16:24:45] <furrywolf> I can't find any like them searching. heh.
[16:25:12] <Tom_itx> like i said, it could be a special cutter
[16:26:30] <Tom_itx> https://www.youtube.com/watch?v=tRvUFABCJeY
[16:29:19] <furrywolf> they almost don't even look like proper cutters...
[16:29:38] <furrywolf> in that they're going to mush their way through material, not cleanly cut it... a distinct lack of angles.
[16:35:00] <Deejay> gn8
[16:38:32] <witnit_> the relief (angles) is ground into the holder
[16:38:49] <witnit_> those look like a custom insert to me
[16:42:26] <witnit_> could be for making a groove on the inside of a large diamter hole, with, what is it called, helical drilling? i forget
[16:44:21] <roycroft> rifling?
[16:44:27] <witnit_> no
[16:44:58] <witnit_> just dropping a cutter in and then roating it around in bigger circles so you can bored a big hole with a small mill
[16:45:04] <witnit_> or recess a groove
[16:45:08] <_methods> looks like one of those 70's or 80's great "idea" roughing inserts
[16:45:29] <_methods> they used to make all kinds of silly geometry inserts
[16:46:57] <witnit> http://www.practicalmachinist.com/vb/attachments/f14/93553d1386798261-just-pics-spiral-milling-deckel-fp3-20131021_111352.jpg
[16:47:03] <witnit> that is just glorious
[16:48:04] <witnit> bet you didnt know you wanted one of those!
[16:49:13] <PetefromTn_> evening folks
[16:49:32] <furrywolf> that looks like one of those things you can be very proud of making on a manual mill, while it's really just a few lines of g-code this century. :P
[16:49:42] <furrywolf> linuxcnc should have no problem cutting that
[16:52:51] <furrywolf> so what is it? heat exchanger? fusee? copper unicorn horn?
[16:53:18] <witnit> pete :) welcome
[16:53:44] <PetefromTn_> Thanks witnit.. Howsitgoin'?
[16:53:46] <_methods> spiral colonoscopy probe
[16:53:49] <witnit> narhwale tusk, for reddit, its like the golden bull, but narwhale
[16:54:11] <witnit> itschagwon gooood
[16:54:32] <PetefromTn_> thats nice..
[16:54:44] <PetefromTn_> worked my first day in the new shop today...
[16:54:57] <witnit> awesome, good atmosphere?
[16:56:11] <PetefromTn_> honestly it was very very nice. It is a small shop, two VMC's one CNC turning center, a pair of nice engine lathes and two vertical knee mills, a decent metrology room with CMM and some plates and a surface gringind area...
[16:56:57] <PetefromTn_> the owner is an 80 year old short Brazilian fellow who was very very nice so far.. I
[16:57:21] <_methods> oh damn you took a regular job
[16:57:39] <PetefromTn_> I spent the morning running their 16x60 manual lathe making some stainless steel turned tubing with thin walls that was kind of a bitch riging like a bell...LOL
[16:58:01] * furrywolf read that as meteorology at first, and was wondering how the heck that fit in...
[16:58:05] <PetefromTn_> methods actually I was not looking for one really but it was offered to me the other day
[16:58:32] <_methods> offer you couldn't refuse lol
[16:58:49] <PetefromTn_> a friend whom I worked with in the last shop recommended me when they asked him about someone else to work there..
[16:59:08] <PetefromTn_> They are paying me pretty decent and it is just part time I agreed to so far.
[16:59:20] <_methods> ah cool
[16:59:25] <_methods> just some supplemental cash
[16:59:39] <PetefromTn_> This way I can still make my own parts here and take advantage of a somewhat more consistent payday with them LOL..hopefully anyways..
[17:01:31] <witnit> dang, i forgot to order din rail mounts with my card, those are the best thing ever
[17:01:58] <witnit> anyone running 7i92 or any eth series yet?
[17:29:59] <zeeshan|2> Tom_itx: that is a cool sphere thing
[17:30:02] <zeeshan|2> i wonder if i can make it in solidworks
[17:30:06] <zeeshan|2> looks challenging
[17:30:43] <[cube]> zee: got this today
[17:30:44] <[cube]> http://www.busybeetools.com/products/metal-lathe-12in-x28in-with-digital-readout.html
[17:30:57] <[cube]> now...how do i get it in the house? ideas? :P
[17:31:23] <[cube]> it has to go up a small porch flight of stairs
[17:31:31] <[cube]> then down a flight to the basement
[17:31:39] <SpeedEvil> Well - it's only 220kg.
[17:31:52] <SpeedEvil> Surely you can just grab it in a bear-hug.
[17:32:09] <[cube]> lol
[17:32:22] <SpeedEvil> Is that 220kg bare.
[17:32:26] <SpeedEvil> or with the chuck/...
[17:32:35] <[cube]> probably with
[17:32:43] <[cube]> i'll take off whatever accessories i can
[17:32:43] <SpeedEvil> I guess pulling off the carriage, tailstock, chuck, could lower that a fair amount
[17:32:50] <[cube]> yeah
[17:33:46] <SpeedEvil> Anchor-bolts and come-a-longs?
[17:33:48] <[cube]> prolly going to bolt a ratchet hoist
[17:33:50] <[cube]> yep
[17:33:56] <[cube]> to the tops of the stairs
[17:34:11] <[cube]> and have a 1000lbs dolly
[17:35:06] <[cube]> moved an 800lbs mill down there 2 weeks ago
[17:35:14] <[cube]> but it was relatively easy because I could take it all apart
[17:35:23] <[cube]> this im certain will be a pita
[17:38:00] <SpeedEvil> I had a 1000lb dolly once.
[17:38:06] <SpeedEvil> Fortunately, she lost some weight.
[17:38:19] <PetefromTn_> ba dum bumb
[17:39:10] <PetefromTn_> a fridge dolly would be able to move that relatively easily I think with a corn fed boy pulling on it LOL...
[17:40:00] <[cube]> haha
[17:40:10] <furrywolf> so the manual for my stepper drivers wants a 470uf cap installed at the driver's power input. how, exactly, do they want this done? the screw terminals aren't large enough to insert both the 16awg zip cord I'm using, the 470uf cap, and the .1uf cap they also want... I was thinking of just splicing the cap into the zip cord a few inches away from the driver, but that sounds like it'll result in a very unprofessional installation...
[17:43:16] <jdh> what kind of stepper driver wants that?
[17:43:25] <furrywolf> "The power supply terminals should have a capacitor of 470uf or greater connected across them" that's pretty hard when they're only big enough for #16 wire!
[17:43:33] <furrywolf> a centent cn0165
[17:44:33] <furrywolf> the cheap-and-lazy solution I'm tempted to do is just slit the zip cord, strip a section, wrap it around the cap's legs, solder...
[17:44:54] <witnit_> is it for you or customer>
[17:45:05] <furrywolf> me. so it has to be done perfectly. :P
[17:45:20] <witnit_> paint little smileys on it when you finish
[17:48:01] <furrywolf> ?
[17:48:47] <PCW> heat shrink, lump in snake style
[17:49:03] <furrywolf> lol
[17:49:14] <furrywolf> the zip cord is enough smaller than the cap that it wouldn't shrink nicely. :)
[17:49:22] <tjtr33> thats 2 diff places "installed at the driver's power input" vs "The power supply terminals should have a capacitor of 470uf or greater connected across them".
[17:49:23] <tjtr33> I'd expect you could just insure the output caps of the power supply were suitably size ( big for bulk and small for hi freq )
[17:49:33] <furrywolf> I'm using some rubycon 1000uf 100v caps... I figure if they say "or greater", double is a good size.
[17:50:06] <witnit_> cut three heatshrinks
[17:50:07] <furrywolf> tjtr: no, they explicitly state the cap needs to be as close to the driver's terminals as possible, and on the driver side of the fuses.
[17:50:25] <tjtr33> ok, but i just quoted you
[17:50:31] <witnit_> two small diameter cord sized and 1 large for the cap and close the ends of it with the two small shrinks
[17:51:01] <furrywolf> tjtr: they mean the power supply terminals OF THE DRIVER, not of the system power supply.
[17:52:15] <furrywolf> I could make it marginally neater with some 2-positional barrier strips, with two runs of zip cord in one side, and the cap on the other...
[17:52:52] <_methods> 50' of detcord and 2 bricks of c4
[17:53:11] <_methods> and a handful of data prime boosters
[17:53:23] <witnit_> inline capacitor enclosure
[17:55:45] <furrywolf> I could just make a power supply board with a bank of caps on the output, but that'll result in ~18in between the drivers and the caps, and I don't know how close they really have to be...
[17:56:50] <witnit_> or you couldbuy huge wire and not hav that ghastly lump
[17:57:01] <furrywolf> lol
[17:57:23] <zeeshan|2> nice [cube]!
[17:57:55] <zeeshan|2> holy cow
[17:57:59] <zeeshan|2> this cube thing was a pain in the ass to make
[17:58:17] <Jymmm> pics or t never happened
[17:58:20] <furrywolf> I could always email mariss and bug him... he's probably to blame for this.
[17:58:55] <witnit_> arent your drivers in an enclosure already?
[17:59:09] <furrywolf> the drivers are little potted aluminum bricks
[17:59:24] <witnit_> in an enclosure?
[17:59:25] <furrywolf> http://www.centent.com/CN0165.html
[17:59:39] <furrywolf> no, right now they're loose on my workbench. I haven't found a suitable enclosure yet.
[18:00:27] <zeeshan|2> http://c1.staticflickr.com/9/8578/15614114133_9a6a639e27_b.jpg http://c1.staticflickr.com/9/8595/16046586680_b181d39b47_b.jpg
[18:00:39] <zeeshan|2> i think i wanna make this on the lathe
[18:00:39] <zeeshan|2> lol
[18:00:51] <furrywolf> for $750 a pop you think they could have stuffed the proper input capacitor into the module. :P
[18:00:56] <witnit_> you must be a bit of a perfectionist if you are concerned about putting them inline, in an enclosure :)
[18:01:03] <zeeshan|2> i can face all 6 sides
[18:01:08] <zeeshan|2> er
[18:01:20] <zeeshan|2> and then hold it with a 4 jaw i think
[18:01:27] <zeeshan|2> yea i can
[18:01:35] <Tom_itx> zeeshan|2, the sphere is easy to do, you just need to be precise
[18:01:46] <zeeshan|2> it was a pain to draw in cad
[18:01:49] <furrywolf> zeeshan: first make the classic turner's cube. the real one, where the inner cube is free.
[18:01:51] <zeeshan|2> hopefully its not a pain on the lathe
[18:01:59] <zeeshan|2> no!
[18:02:02] <zeeshan|2> i like this better
[18:02:19] <furrywolf> witnit: if something's worth doing, it's worth doing right. :P
[18:02:37] <furrywolf> someday I'll sell the machine, and I don't want people going "wow whoever did this was a hack!". :P
[18:03:46] <furrywolf> spheres are a pain on a non-cnc lathe without the proper sphere-making jig...
[18:04:20] <zeeshan|2> Tom_itx: try drawing this in solidworks
[18:04:22] <zeeshan|2> this is a good exercise
[18:04:23] <zeeshan|2> haha
[18:04:45] <furrywolf> I really wish I had time to play with my raytracer... I never did get CSG added...
[18:04:49] <Tom_itx> meh, i'm busy on the control tonight
[18:04:55] <zeeshan|2> another time
[18:05:09] <Tom_itx> i did one of the cubes on the cnc once
[18:05:16] <witnit_> oh, i just dont like to spend that much time on cosmetics, functionality and ease of replacing items was always my interests
[18:05:57] <furrywolf> I'll make a turner's cube once I get this machine running... probably out of a block of wood. wood is cheap. metal is WAY too expensive for non-productive projects.
[18:06:17] <Tom_itx> wood doesn't work as well
[18:06:23] <witnit_> grains
[18:06:24] <zeeshan|2> furrywolf
[18:06:26] <furrywolf> no facing, either. just cut a chunk off the end of a 6x6 and call it good. :P
[18:06:26] <zeeshan|2> your cap thing..
[18:06:27] <Tom_itx> the last few bits want to chip away
[18:06:31] <zeeshan|2> cnc4pc sells a cap module
[18:06:35] <zeeshan|2> for their power supplies
[18:06:49] <Tom_itx> i made a cap module for mine
[18:06:59] <zeeshan|2> http://www.cnc4pc.com/Store/osc/product_info.php?products_id=613
[18:07:03] <zeeshan|2> 3 caps for 62$
[18:07:05] <zeeshan|2> haha
[18:07:15] <Tom_itx> mine was much less
[18:07:20] <zeeshan|2> i hope so!
[18:07:24] <zeeshan|2> i wouldnt pay more than 10 bux for that
[18:07:43] <zeeshan|2> especially with those horrible connectors
[18:07:50] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/caps2.jpg
[18:07:55] <Tom_itx> laen made the boards
[18:08:01] <zeeshan|2> nice!
[18:08:07] <witnit_> oooh pretty
[18:08:11] <Tom_itx> the leds help drain when off too
[18:08:20] <furrywolf> "Has three pairs of diodes, for avoid shorts in the external sources." ...
[18:08:54] <furrywolf> 1) engrish, 2) huh?
[18:09:39] * furrywolf is probably annoying the neighbors by listing to sisters of mercy (not quite at "11", but non-quietly) while playing with the mill
[18:11:17] <tjtr33> furrywolf, the diagram on page 4 figure 3 show the fuse and the zener between the 2 caps. we may disagree but i think these items do not have to be right at the drive.
[18:11:18] <tjtr33> the words 'The power supply terminals should have a capacitor of 470ÎĽf or greater connected across them.' have some ambiguity.
[18:11:33] <zeeshan|2> Tom_itx: i opened up this amplifier board a long time ago for a home audio system that hadn't been powered in years
[18:11:38] <zeeshan|2> ast least 2 years..
[18:11:52] <zeeshan|2> i was scavenging heatsinks from it, and shorting out the caps with a screwdriver
[18:11:56] <zeeshan|2> 10 of them were charged!
[18:12:23] <zeeshan|2> is that normal?
[18:12:30] <zeeshan|2> they dont have a drain like you're doing with your led?
[18:12:53] <furrywolf> capacitors are shipped with shorting straps for a reason.
[18:14:34] <witnit_> check all capacitors those straps go bad
[18:15:07] <furrywolf> witnit: he doesn't have shorting straps. he has caps installed in a product, that he's surprised to find have picked up some charge just sitting there
[18:15:16] <witnit_> yeah i know
[18:15:48] <witnit_> but you cant trust a cap even when they are shorted
[18:20:57] <furrywolf> hrmm, apparantly they've remastered all the old Siouxsie albums... I should find them...
[18:21:03] * furrywolf is getting distracted from capacitors
[18:21:17] * furrywolf has all the old siouxsie on original vinyl!
[18:23:33] <zeeshan|2> furrywolf: dont get distracted
[18:24:25] <furrywolf> lol
[18:24:52] <zeeshan|2> theoretical question of the day, since multiple neighbours are connected together at the transformer neutral, and lets say the neutral isn't tied to the ground at the transformer (someone stole the wire), and then your neighbours ground is also not connected to the neutral bus
[18:24:55] <furrywolf> but playing music on my living room stereo tends to do that...
[18:25:14] <zeeshan|2> and you're trying to install a main panel and about to join the neutral bus and ground together in a new installation
[18:25:26] <zeeshan|2> you could get shocked by touching the neutral right? =)
[18:25:37] <furrywolf> my living room is maybe 18x20ft, and has a pair of 16" 5-way speakers, 14" 6-way speakers, and 12" 4-way speakers stacked up... it's very good at being distracting! (and annoying neighbors)
[18:25:51] <furrywolf> zeeshan: ALL power should be off if you're doing wiring in the panel.
[18:25:56] <zeeshan|2> furry i know.
[18:25:59] <zeeshan|2> power is off
[18:26:03] <zeeshan|2> i still think you can get shocked
[18:26:19] <zeeshan|2> if your neighbour has a a short on their side
[18:26:30] <zeeshan|2> current travels from them, to your neutral wire.
[18:26:37] <furrywolf> as in, if the power company's neutral was hot? it shouldn't be.
[18:26:55] <zeeshan|2> furrywolf: i know it can be
[18:27:03] <zeeshan|2> we used to sell breakers that disconnected neutral too
[18:27:04] <furrywolf> connect the wire to ground first, then to neutral, so at no point you're touching an ungrounded wire. :P
[18:27:06] <witnit_> put it another ground rod?
[18:27:13] <zeeshan|2> people that have generators that feed to their panel spit current out
[18:27:40] <zeeshan|2> furrywolf: yea that is what i would do , and use insulated tools
[18:27:43] <furrywolf> I was doing some work at a trailer once, and the entire trailer was hot... ground rod and all. the ground rod was hot both electrically and thermally!
[18:27:45] <andypugh> “Redefining success” https://picasaweb.google.com/lh/photo/LBoi5b4CsBt_EFhiK0EPftMTjNZETYmyPJy0liipFm0?feat=directlink
[18:28:09] <furrywolf> 120V from ground rod to not-nearby ground.
[18:28:11] <witnit_> oh wow, hot groundrod
[18:28:18] <furrywolf> and wet ground
[18:28:22] <witnit_> O.o
[18:28:27] <zeeshan|2> nice andypugh!
[18:28:28] <_methods> andypugh: spinning?
[18:28:41] <andypugh> That’s the pile of rejected rejects.
[18:28:48] <furrywolf> you could measure it just sticking your meter probe in the dirt...
[18:30:12] <andypugh> I have two complete lamps that I _could_ use, in that at least the parts stay in one piece, but I need to work on the beads. https://picasaweb.google.com/lh/photo/DsniVYc9oQ4uzdnb2nNhcdMTjNZETYmyPJy0liipFm0?feat=directlink
[18:30:28] <furrywolf> I should go grab my klipshs and jbls from storage... then I can really piss the neighbors off. :)
[18:30:32] <furrywolf> klipschs
[18:30:43] <zeeshan|2> andypugh: you need to clean your shop
[18:30:43] <zeeshan|2> lol
[18:30:49] <_methods> andypugh: i like your little drill bit bending jig
[18:31:05] <zeeshan|2> that looks awesome
[18:31:31] <witnit_> andypugh great work
[18:31:55] <andypugh> drill-bit bending jig?
[18:31:56] * furrywolf is still waiting for the link to load, to see what people are talking about
[18:32:12] <witnit> dialup?
[18:32:14] <andypugh> Ah, the contact bending jig using drill-bits as rods?
[18:32:37] <_methods> yeah
[18:32:38] <_methods> heheh
[18:32:54] <_methods> i never thought to just use drill bits for that
[18:33:02] <_methods> i'm always lookin for dowel pins or something
[18:33:09] <_methods> i could just use drill bits
[18:33:16] <_methods> or mold pins
[18:33:22] <furrywolf> witnit: even better. 3G!
[18:33:23] <furrywolf> dialup at least is reliable.
[18:33:57] <furrywolf> most of the problem is everything to do with google loads ten times more javascript than content
[18:34:08] <furrywolf> and for some reason people link to their crap, rather than directly to images...
[18:34:55] <furrywolf> I got the second one to load... a pair of lights?
[18:34:58] <Tom_itx> andypugh, how did you end up getting the lip right?
[18:35:22] <andypugh> furrywolf: Yes.
[18:35:31] <furrywolf> grrrrr. I should just never go to any google links, ever. their crap javascript fails miserably if parts don't load quickly, so I have to repeatedly reload the pages trying to get them to work as more of it is cached...
[18:35:48] <andypugh> Tom_itx: I got a big bit of tube to push against the lip from the tailstock to back it up.
[18:36:00] <Tom_itx> looks nice
[18:37:00] <andypugh> furrywolf: I wish I knew how to link to the picasa photos. If you look the links are “picasaweb” but that isn’t what you get when you click. Very annoying.
[18:37:16] <furrywolf> are those turned or stamped?
[18:37:25] <Tom_itx> he turned them
[18:37:35] <_methods> spun
[18:38:39] <andypugh> Spun from sheet. If you scroll back through the photos you can see the process (sort of)
[18:38:52] <_methods> one of those dying arts anymore
[18:39:00] <furrywolf> excellent work, then
[18:40:13] <andypugh> furrywolf: Does this link work for you? https://picasaweb.google.com/lh/photo/LBoi5b4CsBt_EFhiK0EPftMTjNZETYmyPJy0liipFm0?noredirect=1
[18:40:22] <andypugh> (I manually added “noredirect”)
[18:40:37] <andypugh> No, bother…
[18:41:31] <andypugh> Try again with the other URL.. https://picasaweb.google.com/108164504656404380542/NerACar#6102126377838302450?noredirect=1
[18:42:01] <witnit> I wonder why they use all those extra scripts
[18:42:01] <andypugh> Aha! No redirect. But no photo either.
[18:42:47] <andypugh> https://picasaweb.google.com/108164504656404380542/NerACar?noredirect=1#6102126377838302450
[18:43:03] <andypugh> Aha! The last one works.
[18:43:32] <witnit> all the simple websites seems to work, ebay, craigslist, imgur, reddit, its the fancy ones i usually avoid
[18:43:48] <witnit> deviantart is good
[18:44:10] <furrywolf> ebay is NOT simply. ebay has some of the worst coding I've ever seen, anywhere.
[18:44:11] <furrywolf> simple
[18:44:22] <witnit> it loads when you click
[18:44:36] <witnit> which is key
[18:44:50] <witnit> regardless of the rest of their code hahah
[18:44:57] <archivist> ebay has terrible loading times and abusive tracking from all the adverts
[18:45:20] <witnit> i never had any issues with loading, but i use rss feeds for my ebaying
[18:45:26] <witnit> so i guess thats different
[18:45:42] <furrywolf> they have inexplicably useless things like making page elements 10000px then resizing them with javascript, so they break rendering horribly if the javascript doesn't load...
[18:46:01] <witnit> strange
[18:46:19] <witnit> they did do some weird redierection of searches
[18:46:40] <archivist> photobucket has some terrible stupididty too I get a white screen
[18:46:56] <furrywolf> most of their search url weirdness is to aid in spamming google
[18:49:59] <archivist> switch off 3rd party cookies, I counted around 200 on one fleabay page
[18:52:07] <zeeshan|2> andypugh: how is google images treating you
[18:56:13] <andypugh> zeeshan|2: I have found how to stop it redirecting, which is a start.
[18:56:20] <zeeshan|2> hehe
[18:56:34] <zeeshan|2> i guess every image host has their nuisance
[18:56:58] <_methods> did you try linking to them through google+
[18:58:07] <andypugh> I was trying to _avoid_ google+
[18:58:11] <_methods> ah
[18:58:20] <zeeshan|2> why do peoplke hate google plus?
[18:58:20] <_methods> yeah it's pretty much reviled by all
[18:58:29] <andypugh> The last version of the URL stays at Picasa.
[18:58:29] <zeeshan|2> cause others cant see your content unless theyre signed up?
[18:59:09] <andypugh> I actually like G+ more than Facebook. Facebook baffles me.
[18:59:55] <_methods> yeah
[19:00:04] <_methods> facebook is a steaming pile o' poo
[19:00:50] <witnit_> I never registered on the linuxcnc forums because the requirements were too demanding :/
[19:01:06] <andypugh> They send me emails saying thinfgs like “two new pokes since your last visit”. As far as I can tell there is no way to see what a poke is, or who did it.
[19:01:20] <_methods> i haven't either but it's mainly because the site makes my brain bleed
[19:01:35] <andypugh> witnit_: Sorry about that, but one day I had 2000 spammers to deal with, so we had to make it harder.
[19:01:48] <witnit_> understndable
[19:02:00] <witnit_> I was just like city, stae country, nope
[19:02:53] <Jymmm> _methods: Oh, is THAT why my amazon order says "share on facebook"
[19:13:23] <witnit_> more and more i am feeling like google is becoming to the internet what governing bodies are to societies
[19:14:25] <archivist> I hate browsing ebay and then getting a targeted email from amazon
[19:14:40] <witnit_> targeted ads are very disturbing
[19:14:57] <witnit_> i thought about switch to some tor style browsing system
[19:15:24] <archivist> switch off all 3rd party cookies to stop the tracking
[19:16:02] <witnit_> yeah but im sure they still have a good profiling system for target ads based on ip records
[19:16:17] <mozmck> No, they can track now through invisible images or something like that.
[19:16:35] <witnit_> go on
[19:16:46] <mozmck> I saw an article on it a while back and several ad companies are using that method
[19:16:58] <mozmck> I can't remember offhand where I saw that now.
[19:17:07] <archivist> little 1x1 pixel images
[19:17:30] <witnit_> my biggest concern is with tracking voice and mouse movements
[19:17:32] <mozmck> archivist: you saw that too?
[19:17:50] <archivist> mozmck, I review page code and see them :)
[19:18:06] <mozmck> Ah, I see.
[19:19:05] <mozmck> I think if you block *everything* from all the ad companies it might help, but sites are increasingly using ad server to serve their content
[19:19:14] <witnit_> WOW so tricky
[19:19:20] <archivist> do a pagespeed(or similar) test on a suspect page/site see what resources get loaded
[19:19:48] <witnit_> they can tell exactly when you read their email because the image ports back to their server and logs the time when you opened the "image"
[19:19:56] <archivist> good site will only be a few, bad will have hundreds
[19:20:16] <mozmck> I use adblock plus and ghostery, and some sites I have to whitelist on ghostery to view any content.
[19:20:20] <eeriegeek> You can turn off cross site image loading in some browsers.
[19:20:35] <mozmck> which ones?
[19:20:55] <eeriegeek> firefox and the thuderbird mail reader at least
[19:20:56] <mozmck> I don't trust Chrome for anything (or anything else google)
[19:21:16] <witnit_> sames mozmck
[19:21:22] <mozmck> interesting. I think I do that in thunderbird, but didn't know firefox would do it.
[19:21:58] <eeriegeek> I used to be a config checkbox, but now you have to find it somewhere in the about:config stuff
[19:22:06] <mozmck> ah, I see.
[19:23:07] <eeriegeek> er, *it
[19:23:20] <eeriegeek> I was never a config checkbox
[19:26:07] <witnit_> mozmck promise to be careful working on that config file
[19:26:25] <mozmck> oh?
[19:26:55] <witnit_> when you type "about:config" in the browser
[19:27:07] <mozmck> I hear you can break things if you let your cat modify it
[19:27:37] <witnit_> they must walk across they keyboard three times minumum before lying down on it
[22:55:00] <Jymmm> What's special (if any) about 308-16?
[22:56:17] <Jymmm> and can I harden ss welding rods by chance?
[22:57:17] <zeeshan> whats -16?
[22:57:21] <zeeshan> 308 i know
[22:57:51] <Jymmm> I guess it's like 18-8
[22:58:15] <zeeshan> then its not 308
[22:58:39] <Jymmm> http://www.lincolnelectric.com/en-us/Consumables/Pages/product.aspx?product=Products_Consumable_StainlessNickelandHighAlloy-Excalibur-Excalibur308308H-16%28LincolnElectric%29
[22:58:49] <Jymmm> 308-16
[22:59:06] <zeeshan> i dont know what that 16 is for
[22:59:17] <zeeshan> but in tig, i use 308L for welding 304 stainless
[23:00:18] <Jymmm> says so here too http://www.airgas.com/product/Welding-Products/Filler-Metal/Stick-Electrode-%28SMAW%29/Stick-Electrode---Stainless-Steel/p/HAR3081670
[23:00:30] <zeeshan> its gotta be something to do with the flux
[23:01:05] <Jymmm> http://www.lincolnelectric.com/en-us/support/welding-solutions/Pages/stainless-steel-electrodes.aspx
[23:02:39] <Jymmm> A “16” electrode has a titania or rutile based coating and can be used with both DC and AC polarity.
[23:03:12] <Jymmm> Nice writeup
[23:03:40] <Jymmm> and now we know what L and H are too =)
[23:03:53] <zeeshan> l and h i knew
[23:03:58] <zeeshan> but only when its like 308L or 308H
[23:04:01] <zeeshan> the -16 threw me off
[23:04:59] <Jymmm> It means you can play back in black when welding =)

[23:24:31] <DGMurdockIII> what good cam software someonme ccan use for first ti me use a cnc mechine
[23:25:48] <cradek> the first time you use a cnc machine you should write some very simple gcode by hand and run it
