Back
[00:20:27] <gringos> gringos is now known as Unit41
[00:47:04] <tomp> any suggestions for where to find morse taper 2 holders? (with draw bar, not tang). this is for a benchmaster mill http://www.lathes.co.uk/benchmaster/index.html
[00:48:14] <tomp> btw tony's site is a great resource for small mills/lathes/shapers http://www.lathes.co.uk/index.html
[00:48:28] <anonimasu> hey tomp
[00:48:30] <anonimasu> what's up?
[00:48:51] <tomp> hiyahiyahiya back from tulsa again
[00:50:09] <tomp> this weekend will try to hook my differential encoders up to emc using the digikey parts i found when i got back :)
[00:51:29] <anonimasu> :)
[01:08:01] <ds2> tomp: tried looking at www.littlemachineshop.com? think the HF micromill uses MT2 hodlers
[01:11:05] <tomp> ds2: thanks, i finally found http://www.victornet.com which had collets and end mill adapters. i could buy individual pieces rather than sets. the adapters look the same.
[02:09:02] <ohiopctechDOTcom> uhh...
[02:09:11] <ohiopctechDOTcom> happy friday ppl....
[02:09:37] <SWPadnos> can you substantiate that?
[02:09:58] <ohiopctechDOTcom> well, i'm not dead yet.. so i'm happy i guess!
[02:10:11] <eric_u> we can fix that
[02:10:12] <ohiopctechDOTcom> or the other way round.. not sure!
[02:10:32] <ohiopctechDOTcom> thanks for the offer!
[02:11:34] <ohiopctechDOTcom> http://ohiopctech.com/noth1ng/pfolio/squirrel <- a page i made when i was bored today after i had my digital camera outback with me...
[02:11:47] <ohiopctechDOTcom> if anyone is bored now.. lol
[02:17:31] <Unit41> leeping geenome's
[02:18:32] <ohiopctechDOTcom> ...my poor sheep
[02:18:44] <ohiopctechDOTcom> it's so lifeless now on the front porch
[02:20:58] <Unit41> you must have too much time
[02:21:16] <ohiopctechDOTcom> i do.. i need to find a hooker or somethin
[02:22:00] <Unit41> what kinda stuff do you mill ?
[02:22:15] <eric_u> anyone know how to make a dual boot linux/windows machine with each os on a different hard drive?
[02:22:23] <ohiopctechDOTcom> art-ish stuff mostly..
[02:22:29] <ohiopctechDOTcom> install windows first
[02:22:35] <ohiopctechDOTcom> then make it drive 2
[02:22:36] <Unit41> we should come up with plywood projects people can cut and assemble
[02:22:42] <eric_u> didn't work
[02:22:44] <SWPadnos> use grub in the MBR of the first hard disk, and put Windows on that disk, Linux on the second disk
[02:22:44] <Unit41> like chairs and benches
[02:22:45] <ohiopctechDOTcom> then put the blank linux drive as master
[02:22:48] <ohiopctechDOTcom> then install linux
[02:23:01] <SWPadnos> Windows needs to boot from the first disk
[02:23:06] <ohiopctechDOTcom> grub should pick upthe windows install during the linux install
[02:23:11] <SWPadnos> at least, it's a lot happier if it does
[02:23:36] <SWPadnos> yes, but Linux should be on disk 2, not 1. Windows gets confused if C: isn't BIOS HD 0x80
[02:23:44] <ohiopctechDOTcom> SWPadnos that's right
[02:23:52] <ohiopctechDOTcom> linux on the second disk
[02:23:59] <ohiopctechDOTcom> but install windows first
[02:24:02] <eric_u> I tried the old swap bios trick in grub, but it gives me a batch of crap
[02:24:04] <SWPadnos> yes, always
[02:24:14] <ohiopctechDOTcom> you can alternatively use the windows boot menu to start linux
[02:24:20] <ohiopctechDOTcom> you have to hand edit it thouh
[02:24:20] <eric_u> the volume group thing seems to have messed it up
[02:24:32] <SWPadnos> can the windows menu boot OSes on different disks?
[02:24:42] <ohiopctechDOTcom> yup
[02:24:47] <ohiopctechDOTcom> i did it before
[02:24:53] <SWPadnos> oh, cool. didn't know that
[02:24:55] <ohiopctechDOTcom> if you get the settings jsut right it works
[02:25:03] <SWPadnos> same as grub then ;)
[02:25:18] <eric_u> you can actually boot windows off of the second disk
[02:25:28] <ohiopctechDOTcom> (blindfold your windows when you boot linux tho, so it doesn't get jealous)
[02:25:30] <SWPadnos> it's harder to do it that way
[02:26:05] <ohiopctechDOTcom> i use grub now.. but i can jsut select which rive i want to boot from with my bios
[02:26:10] <eric_u> with the price of hard drives being so low, it surprises me that all the instructions online talk about one disk
[02:26:14] <ohiopctechDOTcom> so i don't need any boot manager really
[02:26:34] <SWPadnos> well, drives are so cheap, you can stick serveral reasonably large installs on one :)
[02:26:49] <eric_u> I suppose
[02:26:51] <ohiopctechDOTcom> i use a machine with ubuntu LTS/windows xp pro dual boot
[02:27:02] <SWPadnos> I just ordered a couple (more) 300G SATA-2 drives for $80 each or thereabouts
[02:27:03] <eric_u> but that cuts down on the max size of the porn collection
[02:27:26] <SWPadnos> I could have gotten less expensive ones, but I wanted to match some I already have for a RAID
[02:27:41] <ohiopctechDOTcom> unit41: i was thinking about some kinda kit i could cnc the parts and sell the other day
[02:27:42] <eric_u> The thought of reinstalling is no fun
[02:27:49] <ohiopctechDOTcom> i didn't come up with anything really...
[02:28:13] <ohiopctechDOTcom> a puzzle maybe
[02:28:16] <SWPadnos> use the HD for data and swap, and boot from separate ~4G USB disks ::
[02:28:21] <Unit41> im looking for partners on projects
[02:28:32] <Unit41> if you wana pair up I can autocad a design
[02:28:38] <eric_u> I guess I could put a third hard drive on this system
[02:29:48] <ohiopctechDOTcom> i have 3 drives/7 partitions a 20 gig, a 30 gig and a 120 gig... the 120 has a 30 gb linux partition and the swap space.. the rest of the space is fat32 for windows
[02:30:03] <ohiopctechDOTcom> * and a dvd burner
[02:31:32] <ohiopctechDOTcom> Unit41: i will have more options of things i can build once my "bigger" cnc router is completed soon
[02:32:00] <Unit41> mine's 20' long
[02:32:16] <ohiopctechDOTcom> your router?
[02:32:18] <Unit41> yaa
[02:32:36] <ohiopctechDOTcom> hmm.. mine should be able to do 24" x 48" all the way to the endges when it's done
[02:32:44] <ohiopctechDOTcom> edges*
[02:32:56] <Unit41> small
[02:33:14] <Unit41> I used a bed frame at first
[02:33:28] <ohiopctechDOTcom> 20 foot long?
[02:33:34] <Unit41> mmmhmm
[02:33:38] <Unit41> I should take some pics
[02:33:45] <ohiopctechDOTcom> YEAH take some pics lol
[02:33:56] <ohiopctechDOTcom> i'll host em on my page if ya need someplace to put them
[02:34:07] <ohiopctechDOTcom> * same offer for anyone with a homebrew machine
[02:34:24] <Unit41> your website has no eye candy
[02:34:28] <Unit41> its not jazzy at all
[02:34:38] <ohiopctechDOTcom> i got like a boatload of storage on my webhost
[02:34:38] <Unit41> learn some css ?
[02:34:54] <ohiopctechDOTcom> i like plain
[02:34:58] <ohiopctechDOTcom> i know css...
[02:35:19] <ohiopctechDOTcom> hardcore industrial.. not fluffy and pretty
[02:35:36] <ohiopctechDOTcom> functional, clean = sexy in my eyes
[02:35:44] <Unit41> nm I see the banner now
[02:36:05] <Unit41> never loaded at first
[02:36:06] <ohiopctechDOTcom> i do plan on adding a bit of spice to it.. but not much
[02:36:14] <ohiopctechDOTcom> i jsut started the design a few weeks ago
[02:36:52] <ohiopctechDOTcom> soo.... i am still coming up with ideas
[02:37:11] <ohiopctechDOTcom> if you got an idea i'd be happy to listen!
[02:37:44] <Unit41> those ones with 2 peices of pipe as a guide ar the best
[02:38:13] <Unit41> angle iron with bearings
[02:38:15] <ohiopctechDOTcom> websites or machines? i'm lost...
[02:38:32] <ohiopctechDOTcom> lol..
[02:38:33] <SWPadnos> angle iron definitely nmakes the best websites
[02:39:01] <Unit41> for sure
[02:39:09] <ohiopctechDOTcom> yeah...
[02:39:13] <ohiopctechDOTcom> !!!
[02:39:22] <Unit41> * Unit41 takes another hit from tha bong
[02:39:39] <ohiopctechDOTcom> * ohiopctechDOTcom says drugz r bad, m'kay!
[02:41:46] <Unit41> m'kay
[02:41:49] <ohiopctechDOTcom> you got a digital camera, Unit41?
[02:42:04] <Unit41> yeah a good one
[02:42:09] <ohiopctechDOTcom> sweet..
[02:42:26] <ohiopctechDOTcom> GO TAKE SOME PICS AND vids of the machine running!
[02:42:28] <ohiopctechDOTcom> ;)
[02:42:34] <Unit41> its not running yet
[02:42:41] <ohiopctechDOTcom> no seriously though.. 20 feet long?
[02:42:45] <Unit41> ya
[02:42:49] <ohiopctechDOTcom> how do you drive the x?
[02:42:54] <ohiopctechDOTcom> belts?
[02:42:57] <ohiopctechDOTcom> rack npinion?
[02:42:59] <Unit41> its steel pipe used for pipelines
[02:43:00] <CIA-8> 03cradek 07TRUNK * 10emc2/scripts/emc.in: I think that was a bad idea to apply to everyone
[02:43:13] <ohiopctechDOTcom> what moves it though?
[02:43:25] <Unit41> just z
[02:43:30] <Unit41> and x
[02:44:06] <Unit41> I need some chain or rack and pinion
[02:44:36] <ohiopctechDOTcom> start collecting old bikes and hook all the chains together!
[02:44:56] <ohiopctechDOTcom> free drive gearing*
[02:44:58] <Unit41> I have 500 oz steppers to make it all work
[02:45:07] <Unit41> oz/in
[02:45:11] <ohiopctechDOTcom> i see a bike in the trash around here at least once a week!
[02:46:00] <Unit41> was thinking about using electro magnets
[02:46:09] <ohiopctechDOTcom> oh my...
[02:46:15] <ohiopctechDOTcom> sounds like a headache
[02:48:48] <ohiopctechDOTcom> what about driving it with a spool and wire/cable
[02:49:09] <ohiopctechDOTcom> aircraft cable*
[02:49:25] <ohiopctechDOTcom> er uh steel rope
[02:50:12] <Unit41> need rack and pinion for that kind of percision
[02:50:20] <Unit41> 20' is alot
[02:50:24] <Unit41> without an encoder
[02:50:30] <ohiopctechDOTcom> yeah...
[02:50:53] <ohiopctechDOTcom> you could cut your own rack and pinion gears on a smaller cnc
[02:51:07] <ohiopctechDOTcom> hell the rack on a manual even
[02:51:25] <ohiopctechDOTcom> make it two ten foot bars...
[02:51:26] <Unit41> never seen that done
[02:51:38] <Unit41> allways wonderd about a plasma though'
[02:52:02] <ohiopctechDOTcom> or even smaller 4 foot sections or something like that
[02:52:25] <ohiopctechDOTcom> with the ends ground you should be able to do it with some precision... doweled and bolted down
[02:53:14] <Unit41> or a spring drive wheel
[02:53:22] <Unit41> to fir around the pipe
[02:53:37] <Unit41> hope to heck it dont slip
[02:53:39] <ohiopctechDOTcom> like uh friction drive?
[02:53:47] <ohiopctechDOTcom> that sound like a possibility!
[02:53:55] <Unit41> and have 2 motors on each side
[02:54:00] <ohiopctechDOTcom> with the pipe radius cut into a rubber wheel
[02:54:15] <ohiopctechDOTcom> then your motor becomes the drive..
[02:54:44] <Unit41> nono this 20' pipe is thick
[02:54:49] <Unit41> its 3/4 inch thick
[02:55:25] <Unit41> sorry 3/4 inch wide and 1/4 inch thick
[02:55:31] <ohiopctechDOTcom> ok, two rubber wheels... mounted with a spacer in between to span the pipe. each wheel with 1/4 of the radius of the pipe
[02:56:23] <ohiopctechDOTcom> something like that for either side of the table.. (1 for each rail)
[02:56:34] <ohiopctechDOTcom> 4 total...
[02:56:55] <ohiopctechDOTcom> anybody else picturing that?
[02:58:27] <ohiopctechDOTcom> O)-(0 <-- looking like that sorta from the end with the table at eye level
[02:58:44] <ohiopctechDOTcom> with the 0's being the pipes/rails
[03:05:21] <Unit41> is wood cutting tedious for a mill ?
[03:05:35] <ohiopctechDOTcom> you can do it really fast!
[03:05:53] <ohiopctechDOTcom> jsut make sure you have a shop vac
[03:07:32] <ohiopctechDOTcom> on something 20' long... you should have multiple heads that can do two different things at once
[03:07:45] <ohiopctechDOTcom> two ten foot heads
[03:07:50] <ohiopctechDOTcom> that overlap slightly
[03:07:58] <Unit41> its only about 5 feet wide though :/
[03:08:22] <Unit41> big enough for a sheet of plywood
[03:09:25] <Unit41> half inch thread rod
[03:10:21] <Unit41> if I could spin a 2 foot ballscrew i would
[03:10:27] <Unit41> 20'
[03:11:38] <ohiopctechDOTcom> grind the ends of some ballscrews till the threads match up, dowel them together... then pin the ballscrews to the dowel
[03:12:43] <ohiopctechDOTcom> end to end, or with a half flat on each end, or with a dovetail kinda joint...
[03:14:35] <Unit41> would be heavy :)
[03:16:13] <Unit41> fuck my body's all burnt up from picking rocks all day
[03:16:25] <Unit41> hurts to sit
[03:17:06] <Unit41> red like a lobster
[03:18:42] <Unit41> I gotta do this for anothe r week yet
[03:18:55] <ohiopctechDOTcom> farming?
[03:19:24] <ohiopctechDOTcom> or prison road crew?
[03:19:38] <Unit41> little of both
[03:20:23] <Unit41> picking rocks for my parrents
[03:20:42] <Unit41> gotta pay my way
[03:21:12] <JymmmEMC> better than weeds
[03:21:29] <Unit41> I love weed spraying
[03:21:41] <JymmmEMC> pulling not wspraying
[03:22:07] <Unit41> they use hormones to make the plant kill itsself
[03:22:51] <Unit41> not really that dangerous even
[03:23:07] <Unit41> pulling sucks worse than rocks
[03:23:24] <Unit41> with a sunburn
[03:24:07] <Unit41> I like weeds cause you can sit in them for a while to evade the sun
[03:52:34] <JymmmEMC> ew
[03:52:41] <JymmmEMC> better you than me
[04:05:21] <ohiopctechDOTcom> is emc2 sleeping now?
[04:05:45] <ohiopctechDOTcom> or is it silently running basment/garage workshop machines in the background?
[04:06:13] <ohiopctechDOTcom> ...all around the world
[04:06:32] <ohiopctechDOTcom> in your neighbors garage... in your old man's tool shed
[04:07:30] <ohiopctechDOTcom> that computer geek down the street is machining parts for his new go-cart with his hombrew cnc...
[04:08:09] <ohiopctechDOTcom> All too busy to chat on irc right now...
[04:18:42] <ds2> is the voltage across an inductor at any point determined by Vapplied - L * dI/dt ?
[04:21:41] <eric_u> it's going to change with the position on the inductor
[04:22:12] <ds2> elaborate?
[04:22:19] <ohiopctechDOTcom> exactly...there may be a formula, but i would just tap it and use a meter...
[04:22:30] <ohiopctechDOTcom> there is waay too many variables
[04:22:34] <ohiopctechDOTcom> waaaaaay*
[04:22:37] <ohiopctechDOTcom> lol
[04:22:43] <eric_u> it's basically linear, I'm thinking of a center tap on a transformer
[04:22:55] <ds2> trying to understand a high voltage generator
[04:23:17] <ds2> if that is correct and I feed in a steep enough triangle wave, I should be able to use that to induce a high voltage
[04:23:20] <eric_u> cut at the middle, and you are going to get half the voltage drop
[04:23:34] <ds2> and if there is a second coil near by, I should get a multiplication determined by the ratio of turns
[04:23:44] <ds2> does this make sense?
[04:23:55] <ohiopctechDOTcom> yup..
[04:24:03] <ds2> so it would work?
[04:24:12] <eric_u> I forget the exact circuit for a voltage doubler, but that is the approximate idea
[04:24:16] <ohiopctechDOTcom> sort of.. in a strange visual electric field kind of way
[04:24:37] <ohiopctechDOTcom> ehh.. don't mind me
[04:24:37] <ds2> toying with the idea of machining a small engine ;)
[04:25:00] <ohiopctechDOTcom> tiny v-8?
[04:25:13] <ds2> this is my first one... so 1 cyl.
[04:25:39] <ohiopctechDOTcom> i bet a harley 2 cyl is documented somewhere.. it could be scaled
[04:25:42] <ohiopctechDOTcom> ;)
[04:25:51] <ohiopctechDOTcom> to make a mini bike?
[04:25:57] <ds2> no, just to play with
[04:26:18] <ds2> gears and cams are too complicated to make so it would be electronically timed
[04:26:32] <ds2> maybe even use EMC as the timing peice ;)
[04:26:47] <ohiopctechDOTcom> simple rotary distributor
[04:26:58] <ds2> but the valves
[04:27:33] <ohiopctechDOTcom> solenoid?
[04:27:41] <ds2> yeah
[04:28:00] <ds2> found a site where someone did it a few years ago... can't find it anymore
[04:28:05] <ohiopctechDOTcom> you could time the solenoid with the same rotary distributor
[04:28:26] <ohiopctechDOTcom> ...different contacts at the right degrees
[04:28:33] <ds2> but it'd be mechanical... software is so much easier
[04:28:41] <ds2> probally a PIC is more practical then EMC
[04:29:04] <ohiopctechDOTcom> think model-a
[04:29:09] <ohiopctechDOTcom> *engine
[04:29:15] <ds2> maybe I am too young, but a distributor is so cavemanish
[04:29:39] <ohiopctechDOTcom> 555 timers
[04:29:46] <ohiopctechDOTcom> with pot adjustable timing
[04:30:02] <ds2> one step at a time... I need to figure out how to generate the 10KV for a spark plug
[04:30:19] <jmkasunich_> an ignition coil
[04:30:25] <ohiopctechDOTcom> exactly
[04:30:29] <ohiopctechDOTcom> straight from jegs
[04:30:31] <ds2> where does one find an ignition coil thesedays?
[04:30:35] <ohiopctechDOTcom> jegs.com
[04:30:37] <jmkasunich_> auto parts store
[04:30:41] <ohiopctechDOTcom> http://jegs.com
[04:31:39] <ohiopctechDOTcom> http://www.jegs.com/webapp/wcs/stores/servlet/category_10001_10002_10681_-1_10369
[04:31:40] <ds2> are they reasonably priced for a toy project?
[04:31:47] <jmkasunich_> $20
[04:32:18] <ds2> oh, that is cheap
[04:32:28] <ds2> the copper is probally worth more then that
[04:32:35] <ohiopctechDOTcom> the first one i clicked on.. a crane cams models was 31.99
[04:32:46] <ohiopctechDOTcom> they aren't very big
[04:32:53] <ohiopctechDOTcom> about the sixe of a pop can
[04:32:58] <ohiopctechDOTcom> size*
[04:33:06] <ds2> I used to play with one back when I was a kid
[04:33:11] <jmkasunich_> the traditional looking ones are $18.99 or $22.99
[04:33:12] <jmkasunich_> http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_750781_-1_10681
[04:33:30] <ds2> looking at those
[04:33:52] <ds2> and I can just feed in a 12V P-P square wave on the DC side to do it?
[04:34:00] <jmkasunich_> nope
[04:34:05] <ds2> oh
[04:34:07] <ohiopctechDOTcom> they run from a car battery
[04:34:11] <ohiopctechDOTcom> so you need lots of amps
[04:34:19] <jmkasunich_> you need to get some current going in it, then open the primary circuit
[04:34:38] <jmkasunich_> one end of coil connects to +12
[04:34:42] <ds2> why can't I feed it a square wave? it sounds exactly like what you are describing
[04:35:00] <ohiopctechDOTcom> it's actually two coils maybe/i think?
[04:35:02] <jmkasunich_> the other end goes thru a high voltage switch (either mechanical (points) or electronic (MOSFET))
[04:35:06] <ohiopctechDOTcom> or two circuts
[04:35:18] <jmkasunich_> you close the switch or turn on the FET, and current starts flowing in the coil
[04:35:29] <jmkasunich_> leave the switch closed enough to let the current build up
[04:35:45] <jmkasunich_> (not sure what the ideal current is, probably an amp or two)
[04:35:48] <jmkasunich_> then open the switch
[04:36:21] <jmkasunich_> when you open it, there is an inductive kick, the primary voltage across the switch becomes a few hundred volts, and the secondary becomes many KV
[04:36:35] <ohiopctechDOTcom> heck, you could buy the enitre ignition system from there to build a race car then just put it all on your mini 1 cyl
[04:36:38] <jmkasunich_> the inductive kick is critical - thats why an ordinary square wave won't work
[04:36:40] <ohiopctechDOTcom> entire*
[04:37:12] <ds2> jmkasunich: what is the difference between opening it and a square wave? (what am I missing here)
[04:37:33] <ohiopctechDOTcom> heck buy one and experiment
[04:37:45] <jmkasunich_> inductive kick is what you are missing
[04:37:46] <ohiopctechDOTcom> just don't touch + and - at the same time
[04:38:03] <ds2> let me put in more details -
[04:38:32] <ds2> connect coil as the collector load on a NPN power transistor; I drive the base with the output of a 555 (0 to 12V)
[04:38:40] <ds2> isn't that what you just described?
[04:38:44] <ohiopctechDOTcom> find one at a junk yard from a ford excort for 3$ and try a simple test circut
[04:39:00] <ds2> (there is a reverse diode to prevent the NPN from frying)
[04:39:07] <jmkasunich_> as long as the NPN power transistor can handle several hundred volts
[04:39:11] <jmkasunich_> you can't use the diode
[04:39:16] <ds2> ahhhhh okay
[04:39:46] <ds2> was hoping i could treat it like i was driving a relay
[04:39:51] <jmkasunich_> the inductive kick that kills transistors, and that the diode is normally used to prevent, it the key to getting high voltage out of an ignition coil
[04:40:28] <jmkasunich_> http://www.rmcybernetics.com/projects/DIY_Devices/homemade_ignition_coil_driver.htm
[04:40:36] <ds2> but that means I can use a heavy duty relay then
[04:40:38] <ohiopctechDOTcom> suggestion... look at some other race car ignition parts that are in the circut with the coil for research...
[04:41:33] <ds2> oh okay, so I can't kill the kick on the coil but I can use it on the transistor
[04:41:56] <ds2> ohiopctechDOTcom: that's a lot of work for a "toy" project
[04:42:21] <jmkasunich_> ds2: did you see the URL I just posted?
[04:42:26] <ds2> cool, I can that circuit with scrap parts
[04:42:49] <ds2> jmkasunich: yep... that's where my comment about using stuff on the transistor
[04:42:54] <jmkasunich_> ok
[04:43:15] <ds2> got a pair of 2N3055's that I got a decade ago for a tesla coil project that never happened
[04:43:22] <ds2> been itching to use them
[04:47:49] <ds2> nice page, jmkasunich_
[04:47:51] <ds2> thanks.
[04:47:59] <jmkasunich_> you're welcome
[04:48:03] <jmkasunich_> and good luck
[04:48:55] <ds2> just need to find out what are the chance of me finding a 10mm dia. or smaller spark plug at Kragens ;)
[04:58:35] <jmkasunich_> goodnight
[05:12:51] <skinnypuppy1334> I've just started reading the manual for GCAM. How many of you are using it?
[05:14:39] <ohiopctechDOTcom> i haven't used it for anything. i have played around inside though
[05:14:45] <ohiopctechDOTcom> a bit*
[05:14:58] <ohiopctechDOTcom> i read part of the manual also
[05:15:10] <ohiopctechDOTcom> enough to get it moving
[05:15:42] <ohiopctechDOTcom> skinnypuppy1334: have you drawn anything with it?
[05:16:29] <skinnypuppy1334> not yet. I just got out of the shop and ordering some brass stock on fleebay
[05:16:54] <ohiopctechDOTcom> right on
[05:17:20] <ohiopctechDOTcom> http://www.metalexpress.net/cgi-bin/index.pl?&ac=acHome&mod=core&sid=d130e27bd0ddc0520f66de03a685244d
[05:17:51] <ohiopctechDOTcom> *they have a shop ion ayton.. i use them sometimes for stock.. i can even pick it up and see the cute blonde ;)
[05:17:57] <ohiopctechDOTcom> in dayton**
[05:18:33] <JymmmEMC> G'night jmkasunich_
[05:19:04] <ohiopctechDOTcom> you got pics of your machine JymmmEMC?
[05:19:32] <ohiopctechDOTcom> ...jsut curious if i have seen them.
[05:20:35] <JymmmEMC> http://farm1.static.flickr.com/166/424362252_1bd7946026_b.jpg
[05:20:50] <ohiopctechDOTcom> sweet!
[05:21:45] <ohiopctechDOTcom> i like the clamping system!
[05:22:29] <JymmmEMC> Thanks, it's just some 20-60-90 blocks I made, then just edge clamp using the bar clamps
[05:22:36] <JymmmEMC> s/20/30/
[05:23:09] <ohiopctechDOTcom> yup.. i thought about buying some of those little bar clamps but couldn't think of anything to use them for... they were on sal eofr 89 cents or something!
[05:23:34] <ohiopctechDOTcom> wtf is wrong with my fingers?
[05:23:45] <ohiopctechDOTcom> geez.. on sale for 89 cents*
[05:24:00] <JymmmEMC> They work ok. I'm working on being able to use the clamps and/or screws when I replace the top
[05:24:41] <JymmmEMC> I already have all the parts, just need to draw and and machien another plate. LOTS of t-buts to install underneith.
[05:24:50] <JymmmEMC> t-nuts
[05:25:15] <ohiopctechDOTcom> right... toe clamping wokrs good if you onl program half the part at a time, then you can move to the other half for clamping the rest of the part
[05:25:32] <ohiopctechDOTcom> i been using a side clamp system on my mini cnc
[05:25:41] <ohiopctechDOTcom> for lexan and wood
[05:26:29] <ohiopctechDOTcom> i use my 6" scale and a c-clap on the edge of the table.. and clamp the scal against the edge of the part/on the corners against a rail
[05:26:36] <ohiopctechDOTcom> c-clamp*
[05:28:29] <ohiopctechDOTcom> that is a really clean design for a machine
[05:31:03] <skinnypuppy1334> My machine crashed, I had to reboot in a live CD.
[05:31:21] <ohiopctechDOTcom> oh noes!
[05:32:37] <skinnypuppy1334> Yeps, screen goes to black when trying to boot. Goes black just as the progress bar under the ubuntu icon gets to full status... doesn't get to the login ..
[05:33:38] <skinnypuppy1334> Could I boot to terminal and try to sudo dpkg-reconfigure xserver-xorg?
[05:33:55] <ohiopctechDOTcom> heck yeah
[05:34:03] <ohiopctechDOTcom> you can always try
[05:34:58] <skinnypuppy1334> Linux noob under the hood, thought I'd ask first. I'll try that out. I'd hate to loose all that install.
[05:35:16] <skinnypuppy1334> thanx
[05:35:23] <ohiopctechDOTcom> uh oh
[06:00:27] <skinnypuppy1334> I'm back. I was expecting one of the grub selections to take me to the terminal prompt... hitting escape on boot gives me the choice of normal boot, a safe boot that takes me to grub>, and memtest.
[06:01:20] <ohiopctechDOTcom> you can get to a grub prompt somehow and type a command to boot to a prompt i believe, but i don't know the command
[06:01:52] <JymmmEMC> skinnypuppy1334: using an LCD display?
[06:03:37] <skinnypuppy1334> No, I'd had 7.04 running a few days and it froze... now it finishes the progress bar booting and never gets to the login prompt.

[14:09:45] <dave_1> anyone have comments on Aram's last post?
[14:12:47] <dave_1> my gosh, must be too early in the morning
[14:13:38] <SWPadnos> waaaaaaay too early
[14:13:49] <dave_1> for night owls yes
[14:13:56] <dave_1> hi steve
[14:14:38] <SWPadnos> hi Dave
[14:14:50] <dave_1> I keep thinking that if Aram wants laser based measurement he will spend more on that than the rest of the machine
[14:14:56] <SWPadnos> I suppose I shouldn't have said anything, since I'm about to go out for breakfast :)
[14:15:00] <SWPadnos> yes he will
[14:15:16] <dave_1> eating is a good thing ... go enjoy
[14:15:17] <SWPadnos> also, I'm not sure how fast a laser measurement system is
[14:15:37] <SWPadnos> thanks, we will ;)
[14:16:07] <dave_1> laser interferometer is pretty fast since you count fringes but way tooooo sensitive
[16:39:19] <JymmmEMC> Depending on what website I got I get different answers... Does this one look right? http://www.powerstream.com/Wire_Size.htm
[16:39:46] <JymmmEMC> specifically 18ga stranded
[16:39:47] <toastydeath> yeah
[16:40:29] <toastydeath> they're not set limits
[16:40:35] <toastydeath> which is why you'll get different answers
[16:41:10] <JymmmEMC> that url says 16A for chassis, another website says 3A
[16:41:27] <JymmmEMC> huge difference - neither mentions solid or stranded though
[16:50:41] <JymmmEMC> This is interesting... "Stranded vs. Solid Wire" http://www.rowand.net/Shop/Tech/WireCapacityChart.htm
[16:53:27] <JymmmEMC> Oh, and in respect to customs fees, one seller told me that there is a free trade agreement between Singapore and the US.
[16:54:18] <jepler> I'm not sure how much I trust that page .. with respect to measuring wire heating, the only figure you care about is the current; the power dissipated in the wire is found by Ohm's law, the current, and the wire's own resistance. (P=I2R).
[16:56:39] <JymmmEMC> jepler: Yeah, lots of charts, all differnet current ratings. The reason I ask is becasue this encloser I have uses an EIA (standard PC computer power) cable, but all the power cords I have are 18GA and I'll be pushing ~12A @ 120VAC thru it.
[16:57:07] <jepler> perhaps it has to do with whether the wire gets too hot in the presence of a short, in which case it does depend on the voltage (the full available current goes through the wire)
[16:58:56] <JymmmEMC> err enclosure
[17:09:14] <vic> Hi all
[17:09:33] <JymmmEMC> jepler: This enclosure is wired internally with 18ga teflon wire. But won't be buy the time I got done with it =) I be po
[17:09:43] <JymmmEMC> s/buy/by/
[17:10:20] <vic> I've a problem with Ubuntu Live CD with EMC2 , can anyone help me?
[17:10:20] <JymmmEMC> It was originally a PS for test automation, but only rated for 5A
[17:10:41] <JymmmEMC> not till we have an idea of the problem =)
[17:11:14] <vic> ok, when I boot my PC with the live cd Gnome appeared with no icons
[17:11:28] <JymmmEMC> First thing.... did you MD5 the iso before burning it?
[17:11:34] <vic> yes
[17:11:48] <JymmmEMC> what speed did you burn it at?
[17:11:58] <vic> ummm I don't know
[17:12:16] <vic> but the same CD runs gnome fine on other pcs
[17:13:08] <JymmmEMC> Well, sounds like you might have a bad drive if it runs fine on other machiens.
[17:13:25] <JymmmEMC> try burning it again at 4x.
[17:13:46] <vic> I have try with "pci=biosirq" but without results
[17:14:02] <JymmmEMC> you could also try md5sum /dev/cdrom too
[17:14:17] <JymmmEMC> and compare that MD5 againest the ISO MD5, they should be the same.
[17:14:39] <JymmmEMC> will take 20 minutes or so
[17:14:41] <vic> ok I'll calculate md5sum again
[17:15:12] <vic> but I think that the CD is fine, I think is a boot option that my PC needs
[17:15:38] <vic> also sound card repeats the same sound all the time
[17:16:12] <JymmmEMC> do you have another cdrom drive you cna toss in the questionable machien?
[17:16:31] <vic> yes
[17:16:38] <JymmmEMC> you could try that
[17:17:02] <vic> I've try on another pc and it boots fine with gnome and the icons in the desktop
[17:17:23] <JymmmEMC> Yes, you said that already, and that is a different cdrom drive too.
[17:17:40] <vic> yes
[17:17:53] <JymmmEMC> I've personally found that if I burn at faster than 4x on some hardware that it doens't read the disc properly.
[17:18:36] <vic> ok I'll recalculate the md5
[17:20:16] <vic> thanks, see you when I finish
[17:24:46] <vic> ok I've finished: the md5sum is ok so the CD is fine
[17:25:39] <JymmmEMC> you ran md5sum /dev/cdrom ???
[17:25:46] <vic> yes
[17:25:49] <JymmmEMC> k
[17:26:06] <JymmmEMC> then try a different drive in that machien.
[17:26:37] <vic> a different drive? it's a laptop, there's only a DVD and a HD
[17:27:30] <JymmmEMC> then try an external drive if it supports booting up that way
[17:28:07] <vic> ok
[17:35:58] <ohiopctechDOTcom> main boot drive is garlic cheese bread, does anyone have some dipping sauce for it?
[17:36:38] <ohiopctechDOTcom> oh, and the grease from the melted cheese is slowing my whole PC down!
[17:36:44] <ohiopctechDOTcom> maybe i should eat it?
[17:38:12] <vic> hey, I've resolved my issue :)
[17:38:22] <JymmmEMC> See, I knew they were twins...
[17:38:36] <JymmmEMC> vic: how so?
[17:38:54] <vic> I've passed the next parameters to the boot= "pnpbios=off pci=usepirqmask"
[17:39:09] <alex_joni> obviously
[17:39:10] <alex_joni> :D
[17:39:12] <alex_joni> hi guys
[17:39:16] <vic> Gnome loads icons and sounds works fine
[17:39:39] <JymmmEMC> evening alex_joni
[17:40:32] <vic> thanks for all guys I'm going to probe EMC :)
[17:40:35] <vic> bye
[17:40:37] <JymmmEMC> Hey, has anyone ever seen a replacement EIA power connector? All I've found ar ethe molded ones.
[17:41:20] <Skullworks_PGAB> "EIA" ?
[17:41:31] <JymmmEMC> Skullworks_PGAB: PC power cord
[17:41:38] <Skullworks_PGAB> ah
[17:42:15] <JymmmEMC> All the cords I have are 18ga moulded, I want to toss on a cord with larger wire size
[17:42:18] <Skullworks_PGAB> should I fetch my Mousre electric catalog?
[17:42:26] <JymmmEMC> Yes, please
[17:42:30] <Skullworks_PGAB> k
[17:43:53] <Skullworks_PGAB> and I have seen ( I have one ) 14ga cords
[17:44:54] <JymmmEMC> Looks like 14ga == 15A which is just what I need
[17:44:55] <Skullworks_PGAB> think I also have a 12ga - but that came from HAAS
[17:47:33] <Skullworks_PGAB> ok they stock a 14 ga.
[17:47:46] <Skullworks_PGAB> 15A rated
[17:48:19] <JymmmEMC> 562-311027 ???
[17:49:18] <JymmmEMC> 562-312019-01
[17:49:40] <Skullworks_PGAB> Qualtek P/N 312019-01 - Mouser Stock no. 562-312019-01
[17:49:58] <JymmmEMC> 9' too, cool
[17:50:01] <Skullworks_PGAB> yup $7.72
[17:50:27] <JymmmEMC> I guess I can order some power resistors and a few smaller caps from them as well.
[17:51:58] <JymmmEMC> Hmmmm, maybe some nice connectors too - if I cna find the amperage rating on them.
[17:51:58] <JymmmEMC> I really should take a pic of this enclosure, it'll be nice when I get done with it.
[17:51:58] <Skullworks_PGAB> I need diodes and caps...
[17:51:58] <Skullworks_PGAB> and some XLR 5 pin connectors...
[17:52:17] <JymmmEMC> Skullworks_PGAB: What are XLr connectors rated at?
[17:52:44] <JymmmEMC> I was thinking of using "CB mic" connectors
[17:52:56] <JymmmEMC> but I'm not sure fof the rating
[17:54:06] <Skullworks_PGAB> don't recall - but I wanted a "latched" connector and I use std 3pin XLR's for 5v - 12v - gnd
[17:54:11] <JymmmEMC> these http://www.bills2way.com/equip/images/4pin.jpg
[17:54:26] <JymmmEMC> they screw in.... lest chance of bumping loose
[17:55:01] <JymmmEMC> It's what I'm using now, but going to higher ratings
[17:55:13] <Skullworks_PGAB> I used those to wire in the HAAS 5C indexer to our Okuma mill
[17:55:27] <JymmmEMC> I'm talking for driving the motors
[17:55:30] <Skullworks_PGAB> they are nice
[17:55:40] <Skullworks_PGAB> yeah - I know
[17:55:47] <JymmmEMC> k =)
[17:56:01] <Skullworks_PGAB> I used it cause it was idiot proof
[17:56:02] <JymmmEMC> I just dont' know the REAL name of them to be able to look up ratings
[17:56:13] <JymmmEMC> Yep, exactly.
[17:56:20] <JymmmEMC> kind abuse proof too
[17:56:20] <Skullworks_PGAB> radio shack stocked them
[17:56:54] <JymmmEMC> RS doesn't list specs like they used to
[17:57:19] <JymmmEMC> http://www.radioshack.com/product/index.jsp?parentPage=search&summary=summary&cp=&productId=2103996&accessories=accessories&kw=cb+connector&techSpecs=techSpecs&currentTab=summary&custRatings=custRatings&sr=1&features=features&origkw=cb+connector&support=support&tab=techSpecs
[17:58:21] <Skullworks_PGAB> no - not abuse proof - the plastic par that holds the pins breaks easy where it comes out of the connector - it allows the plastic to rotate relative to the body
[17:58:45] <JymmmEMC> Cool! Love shorted wires!!!!
[17:59:34] <Skullworks_PGAB> if your leads were not stripped back then your ok
[18:00:05] <Skullworks_PGAB> but it is not confidence inspiring...
[18:00:38] <Skullworks_PGAB> the plastic still retails the pins as a unit
[18:01:38] <Skullworks_PGAB> but there is a chance to short a pin to the body while not connected
[18:01:57] <Unit41> what linux needs is a good MUIDE
[18:02:07] <Unit41> what linux needs is a good MUIDE
[18:02:20] <Unit41> oops
[18:02:28] <JymmmEMC> Skullworks_PGAB: I can't find those CB Mic connectors, any luck on your side?
[18:03:01] <Unit41> developing should be more human interactive
[18:03:34] <Skullworks_PGAB> http://www.radioshack.com/search/index.jsp?kwCatId=&kw=cb%20connector%20female&origkw=cb%20connector%20female&sr=1
[18:03:55] <JymmmEMC> Skullworks_PGAB: no ratings listed.
[18:04:08] <JymmmEMC> I found them on RS site, just not in mouser
[18:04:45] <Skullworks_PGAB> * Skullworks_PGAB is indexing....
[18:04:50] <Unit41> man I just had a fart that felt like a shit that actually was a shit that should have not have been moment
[18:05:28] <Unit41> I will refrain from telling such things
[18:06:32] <Skullworks_PGAB> hmm
[18:07:07] <Skullworks_PGAB> 4pin DIN (pg 918) 100v/4A
[18:08:03] <JymmmEMC> Kobiconn at the top of pg?
[18:08:18] <skunkworks> alex_joni: I have a tool set switch mounted. seems to be repeatable to .0007. close enough for me.
[18:09:38] <Skullworks_PGAB> XLR - 3pin are rate up to 16A
[18:09:44] <lerman> I used some of these for my servo connectors. http://www.fullcompass.com/brand/NEU/Speakon-Speaker-Connectors.html
[18:10:49] <JymmmEMC> lerman: are those plastic or metal housings?
[18:11:06] <lerman> Plastic housings.
[18:11:41] <Skullworks_PGAB> metal are available
[18:11:43] <JymmmEMC> The ratings look great... 20A rms @ 250VAC
[18:11:50] <Skullworks_PGAB> pg 927
[18:12:06] <JymmmEMC> looking
[18:12:45] <lerman> I forget which model I used... But they were easy to install and use.
[18:12:47] <JymmmEMC> POMONA Audio Connectors?
[18:12:51] <alex_joni> skunkworks: nice
[18:13:13] <JymmmEMC> Skullworks_PGAB: POMONA Audio Connectors?
[18:13:20] <Skullworks_PGAB> I think I have a newer cat
[18:13:24] <lerman> I used XLRs for my encoder and limit switch connectors.
[18:13:25] <JymmmEMC> http://www.mouser.com/catalog/630/927.pdf
[18:13:27] <Skullworks_PGAB> just came
[18:13:37] <JymmmEMC> what cat # ?
[18:13:40] <Skullworks_PGAB> no Neutrik
[18:13:54] <Skullworks_PGAB> cat 629
[18:14:00] <JymmmEMC> older =)
[18:14:37] <JymmmEMC> those look like XLR
[18:14:44] <JymmmEMC> http://www.mouser.com/catalog/629/927.pdf
[18:14:55] <Skullworks_PGAB> but there all selling versions of XLR's
[18:15:26] <lerman> Neutrik is NOT a version of XLR. It is rated at much higher current.
[18:15:28] <JymmmEMC> Skullworks_PGAB: I understand, just would like to use connectros that are easily replacable at 4pm on a Sinday if ever needed =)
[18:15:40] <Skullworks_PGAB> I use 5pin XLR's for my unipolar 3A steppers
[18:16:02] <Skullworks_PGAB> I know the feeling
[18:16:22] <JymmmEMC> Though lerman's looked kinda cool, not sure on the interlock though
[18:16:50] <lerman> Interlock?
[18:17:02] <JymmmEMC> lerman: won't come loose easily
[18:17:05] <Skullworks_PGAB> but quality metal XLR's are bomb proof - the cable is the weak link.
[18:17:28] <JymmmEMC> One lil bump of the release tab and you're screwed
[18:18:02] <JymmmEMC> You'll even blow gecko vampire drives =)
[18:18:17] <lerman> The Neutriks have to be pulled than turned, I believe. (Pull the housing back and then turn it, I think.)
[18:18:24] <Skullworks_PGAB> you must have faith - and trust your design
[18:18:39] <lerman> You cannot just pull the cable and have them come loose.
[18:18:53] <JymmmEMC> lerman: the Neutrik's you mean?
[18:18:59] <Skullworks_PGAB> people use DIN plugs all the time with nothing but the pin tension holding the connector in.
[18:19:26] <JymmmEMC> Skullworks_PGAB: cheap bastards
[18:19:39] <JymmmEMC> even I'm not THAT cheap
[18:20:16] <Skullworks_PGAB> Or we could go total HARDCORE and use AMPHONOL Mil grade connectors...
[18:20:21] <JymmmEMC> I am using molex connectors and have them tywraped together - anything you can use as handcuffs is good enough for me =)
[18:20:30] <Unit41> Unit41 is now known as theHand
[18:21:31] <JymmmEMC> Skullworks_PGAB: ok, Sine we are now on the same mouser cat, did you say you found those CB Mic connectors?
[18:21:45] <JymmmEMC> I just need the ratings on them'
[18:21:54] <Skullworks_PGAB> Old Hurco mill had an AMP mil spec round connector for the RS-232 port...
[18:22:17] <Skullworks_PGAB> not the same - close
[18:22:33] <JymmmEMC> ah
[18:22:53] <JymmmEMC> skunkworks: you said these? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=005&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=150120823285&rd=1&rd=1
[18:23:32] <theHand> theHand is now known as Finger12
[18:24:00] <JymmmEMC> Hi petev
[18:24:04] <petev> hi
[18:24:10] <JymmmEMC> lerman: are you using those connectors you mentioned?
[18:24:20] <lerman> Yes.
[18:24:32] <JymmmEMC> petev: Do you know the REAL name for these? http://www.radioshack.com/product/index.jsp?parentPage=search&summary=summary&cp=&productId=2103996&accessories=accessories&kw=cb+connector&techSpecs=techSpecs&currentTab=summary&custRatings=custRatings&sr=1&features=features&origkw=cb+connector&support=support&tab=techSpecs
[18:24:55] <JymmmEMC> lerman: using shielded audio cable too?
[18:25:04] <lerman> Three of them, one for each axis. Plus XLRs for the encoders, limit, and home connectors.
[18:25:44] <lerman> Hmmm. I think I'm using lengths of extension cord for the power cables.
[18:26:15] <JymmmEMC> lerman: I need 4c cable
[18:26:36] <lerman> BTW: I'm using Jon Elson's universal servo controller.
[18:26:39] <JymmmEMC> I'm using Home Depot 4c shielded right now.
[18:27:09] <lerman> I'm using shielded for the encoder, but not for the servos.
[18:27:16] <Skullworks_PGAB> How is the USC working out?
[18:27:29] <lerman> I'm quite happy with it.
[18:28:04] <_petev> sorry Jymmm, my battery died
[18:28:07] <JymmmEMC> np
[18:28:10] <Skullworks_PGAB> are you using an index pulse when homing?
[18:28:20] <JymmmEMC> petev: Do you know the REAL name for these? http://www.radioshack.com/product/index.jsp?parentPage=search&summary=summary&cp=&productId=2103996&accessories=accessories&kw=cb+connector&techSpecs=techSpecs&currentTab=summary&custRatings=custRatings&sr=1&features=features&origkw=cb+connector&support=support&tab=techSpecs
[18:28:38] <_petev> those are usually called circular DIN connectors
[18:28:44] <lerman> No. I'm not. (My encoders don't have an index.)
[18:28:44] <_petev> but there are many types
[18:29:18] <JymmmEMC> petev: no doubt, having ahard time looking in mouser catalog for them. Trying to find the ratings.
[18:29:35] <_petev> what are you trying to connect?
[18:30:06] <Skullworks_PGAB> * Skullworks_PGAB is obsessive about repeatable homing with index...
[18:30:43] <lerman> I would if I could but I can't so I won't.
[18:30:51] <JymmmEMC> _petev: I'm using those now for connecting xylotex drive to my steppers, but now going to 48VDC@3A
[18:31:29] <_petev> Conxall has some sealed plastic versions of the mil type connectors that are pretty cheap
[18:31:38] <_petev> let me see if I can find you a link
[18:31:48] <JymmmEMC> ok
[18:32:10] <Skullworks_PGAB> jym : still battling lost steps?
[18:32:29] <JymmmEMC> I just like those "CB mic" connectors as they seem available anywhere
[18:32:46] <_petev> try this digikey link
[18:32:47] <_petev> http://dkc3.digikey.com/PDF/T072/P0347.pdf
[18:32:53] <_petev> I think mouser carries them too
[18:33:13] <JymmmEMC> Skullworks_PGAB: For the last 18 months. Alright got a new PS and 3900uF 400V caps. Now need the rest of the stuff.... drivers too
[18:33:28] <Skullworks_PGAB> we have been digging in the mouser cat - but can't find them
[18:34:49] <Skullworks_PGAB> I may just bite the bullet and get a Vampire for my Z axis...
[18:34:53] <JymmmEMC> 20-24ga == 2-7A rating.
[18:35:11] <_petev> they have larger ones too
[18:35:17] <_petev> there are mini, maxi, micro, etc
[18:36:08] <JymmmEMC> _petev: I like the CB Mic ones as I cna pick up a replacement at 4pm on a Sinday if I ever needed to.
[18:36:22] <_petev> true, but they aren't sealed
[18:36:25] <JymmmEMC> Just havne't been able to find the ratings or rela name for them.
[18:36:45] <JymmmEMC> _petev: neither is my enclosure =)
[18:37:10] <_petev> well, then I guess it doesn't matter ;-)
[18:37:17] <JymmmEMC> _petev: those connaxal are inline too?
[18:37:24] <JymmmEMC> conxall
[18:37:28] <Skullworks_PGAB> the DIN 4pin uses smaller pins and is rated 100v/4A
[18:37:31] <_petev> yes
[18:37:43] <_petev> they are pretty nice connectors
[18:37:56] <JymmmEMC> _petev: Cool, I'll keep them in mind.
[18:38:01] <_petev> the price is pretty good when compared to real Amphenol mil connectors
[18:38:05] <JymmmEMC> Skullworks_PGAB: cool beans
[18:38:27] <JymmmEMC> _petev: Lets not go there.... we dont need commas in the price =)
[18:38:36] <Skullworks_PGAB> I think your safe with them
[18:38:48] <_petev> I hear you, that's why I usually use these
[18:39:01] <JymmmEMC> Skullworks_PGAB: I think so too.... would jusr like to find the real name for em.
[18:39:06] <_petev> and I usually just use a cord grip at the eclosure and save a set of connectors
[18:39:22] <JymmmEMC> cord grip?
[18:39:44] <JymmmEMC> oh, hardwire to the case?
[18:39:50] <Skullworks_PGAB> post the pics on CNCZone - maybe someone can ID the mugshots.
[18:39:54] <_petev> is a fitting that goes in a typical electrical knockout hole and seals ont he cord
[18:39:55] <jmkasunich_> can you use inline connectors, with a total length from end to end of 4ft or less?
[18:40:12] <JymmmEMC> jmkasunich_: No, needs to be 15'
[18:40:20] <JymmmEMC> well 18' for the Z
[18:40:22] <jmkasunich_> ok
[18:40:38] <JymmmEMC> using energy chain which is taking up all the length
[18:40:40] <jmkasunich_> I have several of these: http://jmkasunich.dyndns.org/pics/P1010001.JPG
[18:40:56] <jmkasunich_> very nice heavy duty seaked
[18:40:59] <jmkasunich_> sealed
[18:41:04] <jmkasunich_> but they have only 2ft of wire on each end
[18:41:16] <JymmmEMC> The stepper arn't sealed... just four leads coming out.
[18:41:48] <JymmmEMC> MY steppers http://www.xylotex.com/StepperMotor.htm
[18:42:04] <Skullworks_PGAB> I may build a combo stepper heatsink/coolant seal.
[18:42:14] <Skullworks_PGAB> just for that reason
[18:42:19] <jmkasunich_> jmkasunich_ is now known as jmkasunich
[18:42:37] <JymmmEMC> I'm using PC power (molex) connectors closest to the motors, and CB Mic connectors on the other end right now.
[18:42:53] <JymmmEMC> I have themolex connectors tie wrapped together
[18:45:16] <JymmmEMC> Anyone have an idea on the bleed resistor value/rating I would for a 3900uF cap coming off the switching PS?
[18:45:39] <Finger12> sometimes l like long walks on de beaches
[18:45:41] <jmkasunich> how many volts? and how fast do you want it to bleed down
[18:46:33] <Skullworks_PGAB> use a 120V halogen bulb

[18:48:44] <jmkasunich> lets assume you use two in parallel (series would be stupid, they're rated at 400V, and the only reason to series caps is to get a higher voltage rating
[18:49:02] <jmkasunich> (or is the 400V a typo?)
[18:49:20] <jmkasunich> anyway, 2 in parallel gives you 2x3900 = 7800uF
[18:49:35] <JymmmEMC> No, they are rated at 400V, I got em for $6/ea - couldn't beat it
[18:49:35] <jmkasunich> which is 0.0078 farads
[18:49:40] <jmkasunich> cool
[18:50:03] <JymmmEMC> I bought 4 so I could sell any spares
[18:50:11] <jmkasunich> how fast do you want it to discharge?
[18:50:45] <jmkasunich> under 10V in 5 seconds? under 1V in 1 second? it makes a big difference
[18:50:48] <JymmmEMC> jmkasunich: It was just suggested that I toss a bleed resistor on them "just in case" but I have nfc what I should use.
[18:51:31] <jmkasunich> since 48VDC isn't particularly dangerous, it probably makes sense to start with a wattage number and let the discharge time be whatever it works out to
[18:51:40] <jmkasunich> so, lets say you can get a 1/2 watt resistor
[18:51:47] <Skullworks_PGAB> figure 10 sec if E-stop will freeze the step/dir
[18:52:00] <jmkasunich> for reliability you don't want to run it at much over 1/3 watt
[18:52:10] <jmkasunich> P = V^2 / R
[18:52:30] <jmkasunich> so R = V^2 / P
[18:52:36] <JymmmEMC> Skullworks_PGAB: I'm wiring in a REAL E-STOP too using a relay and a 100W WW dump resistor
[18:53:18] <jmkasunich> R - 48 * 48 / 0.333 = 6918 ohms, you could use 6.8K or anything higher
[18:53:56] <jmkasunich> the time constant will be R * C = 6800ohms * 0.0078farads = 53 seconds
[18:55:19] <JymmmEMC> jmkasunich: I understnad the caps are to give the BEMF some place to go when using reglated/switch supplies. So will the 53s be ok?
[18:55:22] <jmkasunich> so after 53 seconds, the voltage will drop to 37% of the original value - 17.6V
[18:55:38] <_petev> jymmm, I have a bunch of 20 W resistors that came off the stepper circuitry in my BP
[18:55:47] <_petev> I can send you some if you want
[18:55:53] <jmkasunich> the 53s is the time that the bleeders will take to discharge the caps after you turn everything off
[18:55:54] <_petev> I think they are in the 50 ohm range
[18:56:12] <Finger12> Jymmm was that clamp setup on your table all you ? cause thats genious
[18:56:14] <jmkasunich> 50 ohms is rather low, at 48V they'll draw an amp and burn 48W
[18:56:19] <JymmmEMC> jmkasunich: ok, that sounds good... would take me that long to get into the case anyway =)
[18:56:46] <Finger12> Finger12 is now known as gringos
[18:56:53] <_petev> jmkasunich, 50 ohm is still a pretty slow time constant with 7800 uF
[18:56:57] <JymmmEMC> Finger12: Yes, but I am working on being able to use screws too
[18:57:01] <_petev> I would use a FET to switch them in
[18:57:11] <_petev> or a relay or whatever is handly
[18:57:41] <JymmmEMC> _petev: in respect to charge or just discharge time?
[18:58:06] <JymmmEMC> Let me see if I cna find the quote...
[18:58:26] <gringos> where did you guys get that svn bot ?
[18:58:32] <jmkasunich> _petev: depends on what you have in mind
[18:58:46] <jmkasunich> if you are doing estop and want them to stop the motors, yeah, its slow
[18:59:26] <jmkasunich> if you just want a simple and reliable bleed-down after you power down, I think a high value resistor permanently connected is safer than a low value one that has to be connected by some switching device
[18:59:38] <petev> man, if it's not the battery, it's the wireless
[19:00:06] <alex_joni> gringos: cvs bot in our case.. from cia.vc
[19:00:27] <petev> 15K, 2W is standard value available for motor start cap bleed down
[19:00:42] <JymmmEMC> If a linear regulated or a switching supply is to be used, then a
[19:00:43] <JymmmEMC> > large capacitor should be placed across the output terminals. A 2,000
[19:00:43] <JymmmEMC> > to 10,000 uF capacitor should do.
[19:01:21] <JymmmEMC> But that's all it says. I just read elsewhere that a bleed resistor is a "good idea"
[19:02:31] <JymmmEMC> Now for the real ESTOP, I'm using a 100W at 4ohm dump resistor =)
[19:03:12] <jmkasunich> if the dump resistor is automatically connected across the supply when you switch off, a bleeder is not needed
[19:03:54] <jmkasunich> but 6.8K to 10K at 1/2 watt permanantly connected across the cap can't hurt, and provides bleed-down if something prevents the dump resistor from doing its job
[19:04:15] <JymmmEMC> jmkasunich: Oh, just 1/2 W ???
[19:04:56] <JymmmEMC> * JymmmEMC tries to remember color code.... br blk brn 10K ?
[19:05:00] <Skullworks_PGAB> its a small short
[19:05:13] <JymmmEMC> no 1K
[19:05:46] <jmkasunich> JymmmEMC: read back, I started with 1/2 W and calculated the resistance
[19:05:53] <jmkasunich> cause 1/2 watt is easy to get
[19:06:21] <jmkasunich> 10K is brown/black/orange (5 or 10%) or brown/black/black/red (1%)
[19:06:58] <jmkasunich> if you need faster than 53 seconds bleed-down time, then you use less ohms and more watts
[19:06:59] <JymmmEMC> Yeah, I screwed up the multiplier agian, heh
[19:07:28] <JymmmEMC> I cna pickup a ceramic power resistor for $0.50 at the surplus store
[19:07:50] <JymmmEMC> 10K should be easy to find.
[19:08:01] <jmkasunich> you don't need a power resistor
[19:08:05] <jmkasunich> 10K -> 1/2Watt
[19:08:19] <jmkasunich> if you are going to get a power resistor, then you can use less ohms and get faster bleed
[19:08:57] <JymmmEMC> jmkasunich: Ok.
[19:10:01] <JymmmEMC> Just for the record... I wanted an unreglated supply, but the sheer cost compared to this switching supply and 3900 caps was still cheaper.
[19:10:13] <JymmmEMC> including shipping
[19:11:18] <JymmmEMC> I actually have TWO 48VDC@5.5A swtiching supplies and FOUR 3900uF@400V caps. Figure I'll sell the second set and breka even.
[19:12:02] <JymmmEMC> Any comments on these drives? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=005&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=150120823285&rd=1&rd=1
[19:13:15] <Skullworks_PGAB> used item - sold as-is - from Singapore
[19:13:46] <JymmmEMC> shipping for 3 would be $48
[19:16:02] <gringos> what the heck is XtVaCreateManagedWidget
[19:16:19] <JymmmEMC> http://www.parkermotion.com/manuals/oem/OEM_manuals.htm#OEM650
[19:16:38] <gringos> is this not qt or gtk ?
[19:17:00] <gringos> never herd of XtVa
[19:18:22] <JymmmEMC> Skullworks_PGAB: Yeah I saw that... would be $162 including shipping. Big difference from $461 for 3 G203V's
[19:19:35] <JymmmEMC> Pete is bouncing more than a hutch full of rabbits in heat! LOL
[19:19:55] <gringos> use rabbits instead of a lawnmower

[19:20:09] <gringos> RABBITS
[19:20:16] <_petev> yeah, I think the wifi in my notebook is dying, or something is causing major interfernce
[19:20:19] <JymmmEMC> DUCK SEASON!
[19:20:29] <JymmmEMC> _petev: on the cordless phone?
[19:20:38] <JymmmEMC> or maybe the neighbor is?
[19:20:40] <_petev> no, and its 900mhz
[19:21:18] <Skullworks_PGAB> HARDWIRE and be done with it.
[19:21:41] <_petev> everything is hardwired, except for my notebook
[19:21:50] <JymmmEMC> HA! Nobody in Calif uses corded phones!
[19:22:01] <_petev> that's for sure
[19:22:22] <Skullworks_PGAB> I just escaped From CA
[19:22:25] <JymmmEMC> It took me YEARS to find a corded base that works with no power and multiple cordless handsets
[19:22:45] <Skullworks_PGAB> got to fly over LA zoo and watch it burn...
[19:22:56] <JymmmEMC> Skullworks_PGAB: that cold man, cold.
[19:23:17] <Skullworks_PGAB> acutally It was about 93 deg

[19:23:53] <JymmmEMC> skunkworks: wake up!
[19:23:59] <Skullworks_PGAB> those hills were primed to burn - wasn't a question of if... only how soon.
[19:24:25] <JymmmEMC> All the eucaliptus trees
[19:24:36] <Skullworks_PGAB> and its only going to get worse - CA is going to have a bad fire season.
[19:25:13] <JymmmEMC> Always does... SB National Forest
[19:25:27] <Skullworks_PGAB> Prolly going to go back to water rationing too.
[19:25:40] <Skullworks_PGAB> at least in So Cal

[23:07:55] <skinnypuppy1334> Thanks again for your help with xorg last night. I never could get reconfigure xserver-xorg to give me the proper display res, so I copied the xorg.conf from the /etc/X11 on the live boot to the xorg.conf on the hdd1 install. It got my resolution back up.. but now the restricted driver blanks the screen out after enabeling and rebooting.
[23:08:30] <ohiopctechDOTcom> wow
[23:08:58] <skinnypuppy1334> quick simpe work around for that part atleast
[23:09:07] <SWPadnos> what video card and monitor?
[23:10:41] <skinnypuppy1334> monitor is a vx900 19 inch gateway. Card is an older gforce with 32meg... everything worked more than 5 days even with beryl.. partly my fault, I left it overclocked with the AC off.... it was hung when I got to it in the evening... this is where the probs started.
[23:11:58] <SWPadnos> hmmm. that's a CRT monitor?
[23:12:23] <skinnypuppy1334> Is there a chance that restricted driver has become corrupt? There wasn't any reconfiguring or swapping going on what could change? Yep all 40 or so lbs of it
[23:12:31] <ohiopctechDOTcom> the key right there... overclocked...
[23:12:52] <SWPadnos> I wouldn't bet on the driver getting damaged, but it is possible that the card has been damaged
[23:13:01] <ohiopctechDOTcom> yes...
[23:13:30] <skinnypuppy1334> yep... it's stable so long as it doesn't get over 80 f.... card works fine in live cd, windows screensavers ... etc
[23:13:35] <SWPadnos> try booting into single user mode (press 'e' at the grub prompt, then 'e' again on the kernel line, then add the word 'single' to the end)
[23:13:36] <ohiopctechDOTcom> overclocking is like redlining your bmw!
[23:14:01] <SWPadnos> from there, "startx", then look at the X log, /var/log/Xorg.0.log
[23:14:15] <SWPadnos> or copy it somewhere else and reboot into graphical mode, then look at it with a nicer viewer :)
[23:14:43] <SWPadnos> you can also try reconfiguring and/or reinstalling the nvidia-restricted-modules package
[23:14:58] <SWPadnos> dpkg-reconfigure <whatever the actual package name is>
[23:17:25] <skinnypuppy1334> My celeron is more like a noisy honda than a bmw... Thanks for the advice on what to check SWPadnos I'lll check it out in a bit.
[23:18:44] <SWPadnos> no problem
[23:43:27] <JymmmEMC> yo
[23:45:02] <JymmmEMC> The lights are on but nobody home!
[23:52:31] <anonimasu> Jymmm: heh..
