[01:23:23] <r00t4rd3d> ¿Cómo estás?
[01:25:48] <r00t4rd3d> i wanna goto california and hunt that guy down and get the million bucks
[02:14:29] <DJ9DJ> moin
[02:18:16] <DJ9DJ> hi Jymmm :)
[02:22:57] <Jymmm> hi
[03:29:02] <Loetmichel> mornin'
[06:06:23] <AstroBoi> anybody know the general current ratings on stepper motors from cdroms?
[06:11:04] <archivist_herron> AstroBoi, look at the driving chips specs for a clue, else measure the coil resistance and see what voltage they run on
[06:11:52] <AstroBoi> hmm
[06:12:27] <AstroBoi> all very good ideas.. wonder where i put the circuit boards out of that cdrom :P
[06:13:18] <archivist_herron> but...they are weedy little things
[06:14:28] <L84Supper> probably <100ma since they have 12V to work with
[06:20:09] <AstroBoi> hmm driver chip says .94A typical
[06:20:44] <archivist_herron> is that per output or total for the chip
[06:21:09] <AstroBoi> thats for that particular output
[06:21:20] <AstroBoi> could be .5A per channel i guess
[06:21:43] <archivist_herron> the chip could well be capable of far more than the motor needs
[06:21:49] <AstroBoi> yeah
[06:22:28] <AstroBoi> i was thinking id try around 350mA and see how warm it got :>
[06:23:09] <AstroBoi> course its bolted to a fairly decent size bit of tin in a cdrom
[06:23:42] <AstroBoi> but i doubt they drive it very hard, though the steps seem to be pretty chunky for how far a laser has to move
[06:25:39] <AstroBoi> I expected google to be a bit more helpful actually
[07:42:15] <r00t4rd3d> find old printers
[07:42:18] <r00t4rd3d> better motors
[07:48:12] <r00t4rd3d> It went from cold blizzard to 40 and raining out
[08:54:41] <Jymmm> ~~~ One wheel motorcycle http://www.youtube.com/watch?v=Z1YoCfm7nxU
[08:56:58] <syyl> i would prefer the riotwheel...
[08:57:08] <ReadError> i wouldnt want to brake hard on that
[08:57:11] <syyl> doesnt look so goofy
[09:00:02] <Jymmm> riotwheel is FRICKIN HUGE!!!
[09:00:09] <syyl> jep
[09:00:16] <syyl> no one would mess with it
[09:01:42] <Jymmm> It's pretty fugly actually.... a motorized tractor tire that needs a trailer to transport.
[09:02:06] <syyl> the tire is a bit on the small side :\
[09:02:16] <Jymmm> If it falls over, that's it.
[09:02:49] <Jymmm> That's something I'd expect to see from MAd Max
[09:02:54] <syyl> jep
[09:02:56] <syyl> absolute
[09:03:11] <Jymmm> Which was a MOVIE, not real life =)
[09:03:18] <syyl> whut?
[09:03:22] <Jymmm> lol
[09:04:01] <Jymmm> sorry to pop your delusional fantasy world bubble...
[09:04:15] <syyl> :(
[09:04:17] <jdh> not yet anyway.
[09:04:29] <Jymmm> jdh: (give it a week or so)
[09:04:45] <syyl> time to go over in the machineshop..
[09:05:18] <syyl> have to make a miniature m79 grenade launcher as a desktop model ;)
[09:05:25] <Jymmm> The rybo bike is small enough to fit in the trunk of a honda.
[09:05:35] <Jymmm> syyl: WTF?!
[09:05:39] <jdh> honda trunks can hold a lot.
[09:05:46] <Jymmm> syyl: WORKING TO SCALE BIOTCH!
[09:06:15] <Jymmm> syyl: Nobody is listening, the ATF will never know
[09:06:31] <syyl> hey
[09:06:40] <syyl> when will we see something you made? :D
[09:06:53] <syyl> not just words
[09:07:14] <Jymmm> syyl: Sure, you can see it any time, but only for the split second till it goes... well... nm.

[09:12:31] <Jymmm> http://i54.tinypic.com/k2mo7n.jpg
[09:13:15] <Jymmm> syyl: I show my stuff all the time, you just never look =) ^^^^^^^^^^^^^^^^
[09:20:45] <Jymmm> Optics are not as high quality
[09:21:04] <Jymmm> But I suspect that you can get away with whatever you're doing.
[09:21:22] <jdh> I tried to ask the Keling guy several times about cutting speed for the cheap one they sell. All he ever replies with is generic stuff or what the software accepts.
[09:21:44] <Jymmm> LOL, you expect support?!
[09:21:49] <jdh> mainly, how fast can you cut 3mm acrylic or 1/16" plywood
[09:22:01] <jdh> no support, just pre-sales info.
[09:22:06] <Jymmm> ha!
[09:22:38] <jdh> I'm not sure he really speaks english.
[09:22:44] <Jymmm> It all depends.
[09:23:42] <Jymmm> Even humidity/temp can effect cutting/engraving
[09:25:26] <Jymmm> Wood density, moisture content, resin content
[09:27:46] <Jymmm> jdh: If you are going to cut acrylic, you'll want air assist.
[09:36:43] <L84Supper> the guy at Kelling speaks English very well
[09:37:19] <L84Supper> he got his Phd in the US
[09:37:45] <ReadError> is he from china?
[09:38:05] <L84Supper> originally, yes
[09:38:13] <ReadError> keling = automationtechnology now right?
[09:38:18] <L84Supper> yes
[09:38:32] <ReadError> was it you that visted his warehouse?
[09:38:43] <L84Supper> I've be there several times
[09:39:24] <jdh> never actually spoke to him. Just email
[09:39:59] <ReadError> do they make cutting lasers that dont require the mirrors and glass?
[09:40:03] <ReadError> im very accident prone ;)
[09:40:17] <Jymmm> Sure, fiber lasers
[09:40:26] <Jymmm> or Galvo lasers
[09:40:45] <Jymmm> btw... $$,$$$ and up
[09:41:00] <L84Supper> even he has to travel back to China a few times a year to deal with QC issues
[09:41:19] <Jymmm> galvo and fiber start around $60K USD and UP
[09:42:23] <Jymmm> has anyone worked with silk fabric?
[09:42:37] <L84Supper> patterns or solids?
[09:42:43] <Jymmm> either
[09:43:15] <L84Supper> it's not really in right now :)
[09:43:28] <Jymmm> I just want to know what silk does if you take heat/flame to the edge of it
[09:44:04] <Jymmm> Can you seal the edge of silk like you can nylon/satin fabric?
[09:45:18] <L84Supper> haven't tried but it's become the new thing to work with in materials science
[09:45:32] <L84Supper> engineered silks
[09:46:08] <ArcEye> Hi zultron - are you online
[09:47:56] <L84Supper> Jymmm: according to the garment people it won't melt like synthetics to seal the edge
[09:48:21] <Jymmm> L84Supper: ok, good to know. I'll stick with satin instead
[09:52:38] <L84Supper> silk is a protein chain vs polymer chain, looks like it breaks down vs melts, so it's more similar to a thermoset (epoxy, melamine)
[09:53:10] <Jymmm> Yeah, that's fine. I can adjust the laser accordingly.
[09:53:48] <Jymmm> I can grab a sample to test with.
[09:58:40] <Tecan> http://www.youtube.com/watch?v=y-1D5N7Bzrk
[09:58:49] <Tecan> well done remake
[10:00:43] <L84Supper> E. coli and goats have been genetically modified to produce silk, who knew?
[10:01:02] <Jymmm> e coli???
[10:01:53] <Jymmm> L84Supper: Whatcha talkn bout willis?
[10:02:49] <L84Supper> I shit you not :)
[10:03:44] <L84Supper> http://adsabs.harvard.edu/abs/2010PNAS..10714059X
[10:03:57] <L84Supper> http://www.pnas.org/content/107/32/14059
[10:05:58] <Jymmm> "Most E. coli strains pose no harm to human health, except for serotype O157:H7, which can cause food poisoning in humans and can become life-threatening."
[10:08:43] <Jymmm> http://phys.org/news194539934.html
[10:11:44] <L84Supper> I wonder if the milk also makes better string cheese?
[10:24:08] <zultron> Hi ArcEye what's up?
[10:24:22] <zultron> Whoops, he's gone
[10:52:07] <r00t4rd3d> http://i.imgur.com/PcTDVJF.jpg
[10:52:51] <Jymmm> carry on gift?
[10:54:44] <r00t4rd3d> I still like the Arduino one better
[10:54:45] <r00t4rd3d> http://nootropicdesign.com/defusableclock/
[10:55:09] <L84Supper> http://i691.photobucket.com/albums/vv276/wallymonk/21st%20century%20toys/madbombvest.jpg
[10:59:40] <TekniQue> in college we had these: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv016.cgi?read=93495
[11:00:03] <TekniQue> HP suitcases that looked like a time bomb from any hollywood film ever made
[11:00:28] <TekniQue> keypad and 7 segment display
[11:00:36] <Jymmm> TekniQue: Damn dude, did you mine your own copper ore too?
[11:00:48] <TekniQue> 8085 processor that could be programmed by entering opcodes on the keypad
[11:02:24] <TekniQue> Jymmm: no, but we did have to take exams where we wrote down programs for this thing on paper
[11:02:43] <Jymmm> paper? wuts that?
[11:03:18] <TekniQue> an agricultural product
[11:03:23] <TekniQue> like potatoes and rice
[11:03:31] <Jymmm> Ah, Ganja!
[11:04:05] <Jymmm> starch?
[11:06:48] <Jymmm> I saw a show where a native tribe (S. America) would harvest starch from a native plant running/drain it down a troft letting the solid "pile up" and the liquid drain off the end. They would "bake" these pancake-like things.
[11:22:02] <jdh> I saw one where teh old women sat around and pre-chewed it
[11:22:35] <Jymmm> that's for beer
[11:24:09] <Jymmm> Hey, levers... like a teeter totter... Are they a direct ratio? If I have a 12ft plank, and place the fulcrum point at 4ft, I can "lift" double the weight?
[11:25:34] <Jymmm> or would that be at 3ft?
[11:25:46] <Jymmm> since 6ft would be half, or 1:1
[11:30:02] <cpresser> hi. does anyone have a hint for a cable which i might use to connect the spindle to the vdf?
[11:30:05] <jdh> distance1 * force1 = distance2 * force2
[11:30:27] <cpresser> i am looking for a flexible 3 conductor + shield wire (preferrign european distributors()
[11:39:56] * jdh shrugs
[11:39:59] <jdh> I like the blue stuff.
[11:59:35] <L84Supper> Jymmm: I'd set the fulcrum at 8ft away from the end I was going to stand at. The problem is that you're only going to get 1/2 the movement at the load. Have you considered using pulleys or a forklift?
[12:17:43] <Jymmm> L84Supper: I'm wanting to use it to "test" the load strength of some line. Place a 10lb weight on one end, and see if I can break the line. Either add weight and/or move the fulcrum point, lather rinse, repeat.
[12:35:50] <Spida> cpresser: did you look at audio (speaker) cables?
[12:40:40] <Loetmichel> re @ home
[12:51:32] <andypugh> Bah! My ballscrew and ballnut arrived. But without the ballnut.
[12:51:55] <JT-Shop> no hole in the packing I hope
[12:52:53] <fragalot> you can use the packaging instead of the ballnut
[12:52:57] * fragalot nods
[12:53:01] <fragalot> just takes some creativity
[12:54:02] * Spida imagines a nuts for ballnuts deal between andypugh and the shop where he ordered his ballnut...
[12:54:19] <ReadError> what are those little threaded inserts called?
[12:54:21] * frallzor stares at JT-Shop
[12:54:25] <ReadError> you put them in the back side of wood
[12:54:36] <andypugh> ReadError: Tee-Nuts?
[12:54:38] <ReadError> has some little nubs to dig in
[12:54:44] <ReadError> sort of
[12:54:49] <ReadError> but the base is round
[12:55:04] <jdh> or blind nuts
[12:55:08] <ReadError> blind nuts
[12:55:10] <JT-Shop> it's not polite to stare
[12:55:13] <andypugh> http://www.screwfix.com/p/4-pronged-tee-nut-m8-x-11-pack-of-10/47225
[12:55:13] <ReadError> that sounds about right, thanks
[12:55:44] <ReadError> oh, I was thinking T nuts like i use on my mill, but those look like they are it as well
[12:56:45] <andypugh> JT-Shop: A small hole in the packaging. However the package is 350g lighter than stated on the shipping note, so I suspect that the end fell off the tube in transit, and the parcel company taped it back up, not rrealising that the expensive bit had fallen out :-(
[12:57:19] <JT-Shop> yikes!
[12:57:40] <frallzor> Im sorry mister =/
[12:57:44] <jdh> I got 2 packages that were 9kg lighter than the weight listed on the package. Nobody but me seemed to notice.
[12:58:08] <JT-Shop> I'm waiting on a 71lb package
[12:58:39] <fragalot> I got an empty package once when i ordered ball bearing balls
[12:58:42] <fragalot> :<
[12:59:01] <andypugh> I am hoping that the missing nut is the vendors problem or the shipping co's problem rather than my problem. I waited a month for the nut to come in to stock, so I am especially displeased.
[12:59:11] <fragalot> :/
[12:59:42] <Loetmichel> andypugh: maybe it wasnt and the vendor made it LOOK like it has fallen out?
[13:00:20] <andypugh> fragalot: I got an envelope full of drills, minus the drills. I hate to think what they did to the parcel sorting equipment.
[13:00:29] <fragalot> andypugh: haha
[13:00:33] <Loetmichel> <- is today a bit paranoid
[13:00:48] <fragalot> best failed order I ever had was a whole bag of big rare earth magnets
[13:00:52] <fragalot> took 6 months to deliver
[13:00:56] <andypugh> The vendor is Zapp. I have had decent service from them in the past.
[13:00:58] <fragalot> apparently they stuck to the van's ceiling
[13:01:07] <Loetmichel> fragalot: HARHAR
[13:02:07] <Loetmichel> http://cache.bordom.net/server/?type=image&size=full&id=aHR0cDovL2kuaW1ndXIuY29tL1ZaTkZNLmpwZw%3D%3D <- comes to mind ;-)
[13:02:27] <fragalot> lmao
[13:03:48] <andypugh> Anyone _not_ seen this yet? http://www.youtube.com/watch?v=6EsoWpTO2qg
[13:04:36] <fragalot> I haven't
[13:05:11] <fragalot> is it me or do all the remakes just try and copy the original, yet fail
[13:09:08] <andypugh> fragalot: Hard to say, as I don't speak Korean :-)
[13:10:04] <fragalot> :P
[13:11:49] <ReadError> my frame for my router is 160lb or so
[13:11:54] <ReadError> should be fun carrying that in ;)
[13:12:41] <jdh> that was a pricey accident.
[13:14:27] <andypugh> Maybe less pricey that I first thought. The Bell AH1 (which they say that is) was made in the late 60s.
[13:14:44] <andypugh> I think it has been dressed up to look like an Apache, but isn't.
[13:15:09] <jdh> I see one for sale for only $700k
[13:17:10] <andypugh> If you pause the video, there are only two rotor blades.
[13:20:06] <fragalot> that doesn't really mean much
[13:20:15] <fragalot> there could be 4, neatly synchronized with the camera
[13:20:16] <fragalot> :P
[13:21:32] <andypugh> fragalot: Err, no, I don't think that there can be..
[13:22:05] <fragalot> yeah no :)
[13:41:24] <andypugh> Since 16/8/2012 I have had notification emails about 143 new user registrations to the forums.
[13:42:06] <andypugh> Ah, no, that's not right
[13:42:58] <andypugh> I just noticed, that's 143 sets of threads as Gmail sees them. The actual number of subscribers is rather higher.
[13:48:35] <r00t4rd3d> is new user registrations up from normal?
[13:49:06] <r00t4rd3d> what i really would like to know is if they jumped up after upgrading the forum software
[13:49:39] <r00t4rd3d> tjb1, my OBDII made me 100 bucks today
[13:49:45] <tjb1> hows that
[13:50:34] <r00t4rd3d> my buddys friends truck wasnt running right, engine light on, scanned it, cylinder #2 wasnt firing, changed the wire and plug, fixed.
[13:52:00] <tjb1> and you got 100...
[13:52:12] <r00t4rd3d> didnt even ask for it
[13:52:22] <alex4nder> r00t4rd3d: what scanner do you use?
[13:52:35] <r00t4rd3d> bluetooth obdII elm327
[13:52:45] <alex4nder> cool
[13:53:00] <jdh> most parts stores around here will read your codes for free.
[13:53:41] <r00t4rd3d> http://www.ebay.com/itm/ELM327-V1-5-OBD-II-OBD-2-Bluetooth-Auto-Car-Diagnostic-Interface-Scanner-/190754612816?pt=LH_DefaultDomain_0&hash=item2c69dc6650
[13:54:39] <jdh> r00t: works with android?
[13:54:43] <r00t4rd3d> yeah
[13:54:49] <tjb1> Not with SGS3
[13:55:02] <jdh> cool. I have a $100 normal one.
[13:55:32] <jdh> why not s3?
[13:55:37] <tjb1> r00t4rd3d: I got some sweet nfc tags
[13:55:40] <tjb1> I dont know, cant connect
[13:55:43] <r00t4rd3d> tjb1, I ended up changing all the wires and plugs too after I fixed the engine light and rough running so it was worth 100
[13:56:23] <r00t4rd3d> android 4.2.1 has BT issues
[13:56:29] <r00t4rd3d> on some devices
[13:56:55] <tjb1> I never tried it on a ROM that wasnt built off 4.2.1
[13:57:11] <andypugh> Well, 9 new registrations today. Which struck me as rather more than usual.
[13:57:13] <r00t4rd3d> try a JB rom and i bet it will
[13:57:33] <tjb1> 4.2 is jb
[13:57:37] <jdh> mine is 4.1.2
[13:57:38] <r00t4rd3d> err ics
[13:57:55] <tjb1> my phone came with jb, can I go down to ics?
[13:58:24] <r00t4rd3d> matters if the factory image is somewhere
[13:58:51] <jdh> heh... quadruple-tap your android version
[13:58:54] <tjb1> works on the n7, not gonna play with phone anymore
[13:59:04] <tjb1> I already have to switch roms every weekend
[13:59:47] <tjb1> cyanogenmod cant seem to figure out how to make data work
[14:00:17] <r00t4rd3d> http://samsung-updates.com/device/?id=SCH-I535
[14:00:59] <tjb1> not gonna happen
[14:01:47] <tjb1> guy suckers you into paying for the app because of another option to make it work
[14:01:58] <tjb1> should of requested refund as soon as it didnt work
[14:02:27] <r00t4rd3d> you paid for it ?
[14:02:28] <r00t4rd3d> lol
[14:02:59] <tjb1> Well there was some option to make bt work
[14:03:02] <tjb1> Yeah, it didnt.
[14:03:31] <jdh> surely they woudln't have taken that out
[14:03:37] <jdh> <urk>
[14:03:59] <r00t4rd3d> http://www.youtube.com/watch?v=eEjR-Z2WizM
[14:07:01] <tjb1> Nice
[14:07:19] <tjb1> NFC tag set to open pandora, volume max and then using the same tag again closes pandora and turns volume down
[14:09:37] <tjb1> Im going to block papa johns from emailing me
[14:09:44] <tjb1> Everyday, "dont forget to use your coupon"
[14:11:25] <r00t4rd3d> or unsubsribe
[14:26:59] <frallzor> weeey so far so good, new settings seems to be working
[14:29:38] * JT-Shop got my 71lb package and all the parts are there :)
[14:29:48] <jdh> any extra ball nuts?
[14:30:01] <frallzor> all my parts are there too, but in the machines being...machined =P
[14:31:29] <JT-Shop> except for on port plug that is sheared off it looks ok
[14:32:06] <skunkworks> plastic?
[14:35:21] <JT-Shop> aluminum I think
[14:35:28] <jdh> make a new one!
[14:36:08] <JT-Shop> it still seals the hole fine, might be a challange when the time comes to connect the hoses up
[14:48:57] <r00t4rd3d> how hot can normal spray paint get before it burns off?
[14:54:33] <r00t4rd3d> Jymmm or archivist
[14:56:39] <r00t4rd3d> Im gonna paint my engine block with regular spray paint
[14:57:15] <r00t4rd3d> i doubt it gets over 150F
[14:58:27] <jdh> why not splurge on high-temp paint?
[15:00:16] <r00t4rd3d> cause the block is tiny and I got some flat black already
[15:00:34] <jdh> ok.
[15:01:14] <jdh> "sorry, your warranty is void. It overheated due to application of insulative paint"
[15:01:41] <r00t4rd3d> there is no warranty

[15:02:26] <jdh> htey make a burnt copper one too1
[15:03:11] <r00t4rd3d> I know all about VHT, just dont wanna spend it if i dont got too
[15:03:32] <r00t4rd3d> i dont think the block gets hot enough for a high heat paint
[15:09:01] <ReadError> why do i have like 6 harlem shake videos in my work email today
[15:12:09] <L84Supper> r00t4rd3d: the acrylics they use are probably good up to no more than 200 deg C
[15:12:43] <r00t4rd3d> yeah i was told that in ##physics
[15:12:54] <r00t4rd3d> and i just read this on the motor bicycling forums:
[15:12:57] <r00t4rd3d> "ive painted several engines black with cheap krylon enamel(not designed for high temps). It never burns off and ive done it on 5 engines. "
[15:13:29] <r00t4rd3d> all i need
[15:13:31] <L84Supper> prep is important for adhesion
[15:13:39] <frallzor> allmost goood wood, fucked up 1 part in the end, but no biggie, re-make tomorrow =)
[15:13:46] <r00t4rd3d> its brand new so prep is done :)
[15:14:13] <r00t4rd3d> i washed it with soap and water to get all the grease/oil residue off
[15:14:29] <L84Supper> followed by acetone or laquer thinner?
[15:15:03] <L84Supper> up to you
[15:15:03] <r00t4rd3d> no
[15:15:07] <r00t4rd3d> i havent
[15:15:17] <r00t4rd3d> i got some acetone though
[15:15:36] <r00t4rd3d> my meth lab is stocked
[15:16:30] <L84Supper> speaking of which I just came back with pseudoephedrine hydrochloride
[15:16:41] <r00t4rd3d> nice
[15:16:42] <jdh> I scored some yesterday
[15:16:44] <L84Supper> seems the limit is two boxes o matter what size at a time
[15:16:53] <jdh> I could only get one box
[15:17:30] <L84Supper> walmart generic, and they required a drivers license, state id or passport was no good
[15:17:54] <L84Supper> so it's just arbitrary and capricious
[15:18:07] <r00t4rd3d> you gonna whip up a batch?
[15:18:11] <jdh> mine came from Sam's, which is walmart in a larger box
[15:19:40] <L84Supper> trying to clear my sinuses, no I'm infecting everyone around me

[15:50:52] <l2> Hello. =)
[15:52:08] <l2> I have a functional real time kernel in Ubuntu 12.04 LTS with linuxcnc installed. When I attempt to launch Stepconf from the CLI I get the following error. I have found no solution on google.
[15:52:23] <l2> File "./stepconf", line 36, in <module>
[15:52:23] <l2> import hal
[15:52:23] <l2> ImportError: No module named hal
[15:52:44] <l2> Anyone have any ideas?
[15:57:18] <Jymmm> Having a bad day? http://www.wimp.com/badmorning/
[15:58:25] <r00t4rd3d> i dont dare open that
[15:59:08] <ReadError> how was he planning to get out anyways
[15:59:13] <ReadError> with another car in front of him?
[16:01:54] <tjb1> spent more time cleaning his car than anyone up here
[16:05:13] <r00t4rd3d> i would have started it before cleaning it so it was warm when i was done.
[16:05:21] <r00t4rd3d> dumbass
[16:06:31] <r00t4rd3d> ReadError, are you an asian woman?
[16:07:24] <r00t4rd3d> there is more to cars then turning left

[16:08:39] <r00t4rd3d> hey its the gn8 bot
[16:12:28] <andypugh> l2 Does anything else work?
[16:12:38] <andypugh> Ah, I missed him.
[17:12:34] <Nick001-Shop> Can a stepper motor loop be closed with a linear scale?
[17:18:47] <tjtr33> http://www.youtube.com/watch?v=M8ijWbg_seI
[17:18:57] <L84Supper> sure, anything with accurate feedback
[17:19:22] <r00t4rd3d> lets form a posse and go hunt down that cop for the million
[17:21:13] <ReadError> i dont watch the news
[17:21:17] <ReadError> what did he do?
[17:21:23] <r00t4rd3d> shot other cops
[17:21:26] <ReadError> why
[17:21:33] <r00t4rd3d> mental
[17:21:46] <r00t4rd3d> thinking the man was out to get him
[17:22:05] <L84Supper> unhappy, got fired, has an agenda and a manifesto
[17:22:05] <r00t4rd3d> they fired him from th LAPD
[17:22:28] <L84Supper> what the news says anyway
[17:22:39] <r00t4rd3d> pope is getting out
[17:22:59] <L84Supper> same reasons?
[17:23:01] <tjtr33> the vid for steppers with linear scales sez "Hostmot2-Stepgen was changed so that homing works on the Index of GMS." a gms is a linear glass scale
[17:23:35] <r00t4rd3d> is that a question or a statement?
[17:23:52] <tjtr33> fact
[17:24:44] <Nick001-Shop> anything in the wiki on this for the steppers?
[17:24:44] <tjtr33> Glasmesstäben = glass scale
[17:25:02] <tjtr33> see the video about your Q?
[17:25:20] <Nick001-Shop> link?
[17:25:28] <tjtr33> <tjtr33> http://www.youtube.com/watch?v=M8ijWbg_seI
[17:25:39] <Nick001-Shop> thanks
[17:26:00] <tjtr33> np
[17:28:52] <andypugh> Nick001-Shop: You would probably do it by running the stepgen in velocity mode and a PID loop closed by the linear scale position. It ought to work nicely.
[17:29:41] <andypugh> It's theoretically possible to recover from a stall too. (by winding the adaptive feed down, then up again so it can find the correct position)
[17:31:07] <andypugh> That machine in the video deserves better than steppers!
[17:31:47] <tjtr33> hermle? deckel?
[17:31:57] <andypugh> Looks like a Deckel to me
[17:33:39] <Nick001-Shop> andy - still have to get the steppers running. The 1 glass scale seems to be working-can see the a&b moving and I did detect the index. Have to hookup the second one. Just got all rhe different amp connectors that I needed.
[17:34:38] <tjtr33> what model/make scale?
[17:39:43] <Nick001-Shop> Acu-rite about 6" scale - have about 5" travel in the slides. The decks are 18" square.
[17:47:36] <tjtr33> good scales, hope you have good luck using them, i have 3 slides with DRC scales, like Acurite 1um but no index
[17:47:59] <r00t4rd3d> http://www.industruino.com/
[17:49:28] <andypugh> g'night folks
[17:50:36] <Nick001-Shop> Pretty sure I have an index. the wiring diagram indicated it and I did see it on halscope , then I lost the signal - haven't had the time to get back to it to see what happened.
[18:07:09] <tjtr33> Nick001-Shop, may be of use, i hear the pinouts are same, but dont rely on that, check the colors and use a scope http://www.acu-rite.com/pdf/manuals/SENC150sept05.pdf
[18:16:30] <Nick001-Shop> determined it was a digital differential - pin 7 is vcc and connected to pin 6 by ohmmeter. A,A/,B,B/ are pinned correctly. Pin 8&9 are for index and I did see that on halscope and then lost it somehow.
[18:17:15] <Nick001-Shop> Will have to scope the inex pins to see whats I can find
[18:17:25] <Nick001-Shop> index
[18:30:15] <tjtr33> those numbers look good for page 17 , titled 'analog differential'
[18:34:58] <tjtr33> er 'digital differential' sorry
[18:36:10] <ReadError> got 300 teenuts to try to install
[18:36:15] <ReadError> this should be fun
[18:36:39] <Nick001-Shop> digital-pin1 NC analog pin1-ground, goes to case
[18:36:52] <tjtr33> Nick001-Shop, which makes 6 to 7 a short of vcc to gnd, dont power up again till you check that
[18:37:57] <tjtr33> er, just check the diagram on p17, something is different
[18:38:42] <tjtr33> top is digital bottom is analog
[18:38:48] <Nick001-Shop> 6 & 7 short according to ohmmeter and that's where I hooked up the 5vdc and no smoke -).
[18:39:24] <tjtr33> ok, that print does not apply
[18:42:21] <Nick001-Shop> A & B work ok - just lost the index signal after hitting it a few times on halscope. Also, just using A'B'I and leaving the /'s disconnected. Have to hookup the converter and see what I get.
[18:44:11] <tjtr33> this page 14 makes sense pin wise http://www.acu-rite.com/pdf/manuals/SENC50apr09.pdf but is analog differential
[18:44:57] <tjtr33> you get square wave on A & B
[18:45:00] <tjtr33> ?
[18:49:44] <Nick001-Shop> haven't put a scope to it yet
[18:54:51] <tjtr33> i think a 5V sine wave that was ctrd at 2.5V could trigger a TTL input and act 'like' a TTL sqr wave ( poorly, could change the counters )
[18:55:21] <tjtr33> poorly, but could

[19:21:45] <ReadError> i use isoalcohol for most things
[19:22:06] <Jymmm> ReadError: That's the one thing you DONT want to use on it
[19:22:44] <Jymmm> acrylic + alcohol = bad
[19:22:55] <Jymmm> same with PP + alcohol
[19:23:02] <ReadError> i guess i will stick with good ole compressed air

[19:24:09] <ReadError> UPS is going to hate me so much after this week lol
[19:24:11] <Jymmm> even charcoal lighter fluid is fine (and does a damn good job removing lithium grease btw)
[19:24:37] <ReadError> got my collet set today too
[19:24:50] <ReadError> im fairly certain i got everything
[19:25:03] <ReadError> i need to get a 4" hose from amazon (already got the shopvac adapter)
[19:25:37] <Jymmm> ReadError: and I use denatured alcohol for everything, I buy it by the gallons
[20:31:35] <gene77> John, you keep that up and I'll have to actually put speakers on these machines here in the shoop
[21:22:58] <gene77> Humm, I just discovered one of the reasons a #209 nipple and the #209 are such a sloppy fit, CCI's 209's can be as much as .007 out of round!
[21:26:45] <jdh> primers?
[21:27:18] <gene77> Yeah
[21:27:25] <jdh> what's a 209 for
[21:28:05] <gene77> cardboard based shot shells don't care, but steel BP nipples do.
[21:28:10] <jdh> 300s and 500s
[21:28:25] <gene77> whatzat
[21:28:28] <jdh> err... I have 300s and 500s, never heard of a 209
[21:28:52] <jdh> large and small pistol primers
[21:29:05] <gene77> Oh, those are rifle primers, this is shot shell, also used for most inline BP 50's
[21:29:37] <gene77> which is what I am making, a new nipple
[21:30:57] <gene77> The OEM nipple blows 90% of its fire out the side because it is actually too hot for black
[21:31:58] <gene77> But the Blackhorn 209 powder needs a tactical nuke to light it, so needs the full power of a std shotshell #209 primer
[21:32:31] <gene77> The difference on the target at 50 yards is about a foot smaller a group.
[21:34:18] <gene77> I'm outta here for the night, still need to bore 6 holes and cut one slot to complete it.
[21:35:31] <r00t4rd3d> Ive painted and polished cast aluminum to a mirror finish by hand all day
