[00:27:12] <malcom2073> Nah man, it's like the leaded stuff, and batteries. I'm SURE people follow the disposal instructions, don't they?
[00:27:41] <XXCoder> thats crazy
[00:28:01] <furrywolf> the good news is it's so expensive no one will actually buy one.
[00:28:49] <XXCoder> maybe people who thought monster cables meant better found at $200 per cable would buy that
[00:29:04] <furrywolf> lol

"Our unique liquid metal conductors allow electrons to flow more freely than outdated copper conductors, give your sound clarity and nuance as you've never heard before! Starting at only $1499.99 for a pair of our premium 3-foot cables."
[00:30:39] <renesis> 00:28 < XXCoder> maybe people who thought monster cables meant better found at $200 per cable would buy that
[00:30:51] <renesis> theyre not bad cables if you can get an artist or distributor discount
[00:30:57] <renesis> they have lifetime warranty
[00:31:09] <XXCoder> NaK cables lol
[00:31:11] <renesis> but yeah @ full price theyre a joke
[00:31:22] <renesis> hosa cable ftw
[00:31:56] <renesis> except for the hosa cable with switchcraft ends, fuck all that dinosaur shit
[00:31:56] <furrywolf> they'd have to be made out of crystal-clear jacketing with some kind of inner texture so you can see the liquid metal squish as you flex the cables...
[00:32:28] <renesis> so normal crap 'audiophile' speaker cable
[00:32:44] <renesis> i do love how the lens effect of the cable makes the tiny conductors look huge
[00:33:12] <renesis> cable leaks would suck
[00:33:35] <furrywolf> I have some old monster cable that is legitimately 10AWG... but I bought it at yard sales, not retail.
[00:33:53] <renesis> the wire is usually fine, they redesign the ends all the time
[00:33:57] <furrywolf> I'm not using it, because it doesn't fit in the terminals on any of my speakers. :P
[00:34:08] <renesis> custom plastic overmolds, weird boots

[00:34:47] -!- TTN has quit [Ping timeout: 252 seconds]
[00:35:11] <renesis> their mid grade (pro) uses rean XLR, which is neutriks consumer brand
[00:35:21] <furrywolf> lamp cord makes excellent speaker wire, as it has heavier, tougher insulation, and unlike speaker wire, they get sued if they invent their own gauge system, and sell undersized wire.
[00:35:38] <renesis> and the high grade (edge) use neutrik nc3, so basically cable full of awesome
[00:35:49] <XXCoder> Just use gauge 000 ;)
[00:35:58] <renesis> furrywolf: i dont like how it splits
[00:36:05] <renesis> sometimes the insulation will be thin on one side
[00:36:18] <furrywolf> only total crap... and speaker wire can do that too.
[00:36:26] <renesis> but yeah thats basically what consumer speaker cable is, lamp cable is usually better insulation

[00:39:35] <renesis> you can get it 12/4 for biamp speakers, use all of the speakon posts
[00:39:38] <furrywolf> lol
[00:39:51] <renesis> whats lol
[00:39:53] <furrywolf> I don't have fancy terminations. I use consumer-grade speakers with binding posts.
[00:40:08] <furrywolf> lol is because that's just SO cord.
[00:40:08] <renesis> pomona banana plugs are not expensive
[00:40:24] <zeeshan> furrywolf: who you talkin to
[00:40:25] <furrywolf> some of them have binding posts, others have spring clips.
[00:40:28] <zeeshan> renesis?
[00:40:28] <renesis> and speakons and XLR are a few dollar each
[00:40:28] <zeeshan> :P
[00:40:43] <renesis> furrywolf: right i would just twist and insert
[00:40:57] * zeeshan unignores renesis
[00:41:01] <renesis> tho most those binding posts are made to accept banana plug
[00:41:03] <furrywolf> I'm not spending $50 on connectors when I most expensive speakers I have cost me $75. (the JBL 4311s)
[00:41:14] <furrywolf> s/I/the
[00:41:18] <renesis> theyre not always .75" spaced now because fuckin europeans
[00:41:48] <renesis> it would be like $10-15 on connections
[00:42:01] <renesis> and maybe $10-15 in cable, you can buy it at home depot or lowes
[00:42:11] <furrywolf> I'm happy with my flat-4 trailer wire. :P
[00:42:18] <XXCoder> make your own connectors
[00:42:21] <renesis> yeah that works
[00:42:25] <renesis> xxcoder: wot
[00:42:39] <zeeshan> whats wrong with speaker wire

[00:43:34] <zeeshan> lol
[00:43:46] <renesis> furrywolf: yeah i dont like how the insulation doesnt always tear away even
[00:43:52] <renesis> same with standard speaker cable, tho

[00:44:45] <zeeshan> thats what i used when i did my stereo in the old beater
[00:45:09] <renesis> for that i would prob used twisted teflon
[00:45:16] <furrywolf> I like it because it lets me run a single cable then easily split it to two speakers, it's color-coded so you don't have to try looking for tiny writing or feeling for a rib on one side, it's #16 which is plenty thick for full-range speakers, it has decently tough insulation (meant to survive in the open under a trailer), and it's cheap.
[00:45:43] <renesis> right thats why pro audio likes the type of cable i linked to
[00:46:00] <zeeshan> renesis is a pro audio expert
[00:46:05] <renesis> all the reasons you said, except outer insulation
[00:46:19] <furrywolf> and cheap.

[00:54:25] <renesis> on RCA cables built into balanced cables it would make sense
[00:54:43] <renesis> but on the consumer cables i took apart, we laughed because the shield wasnt connected on either side

[01:01:28] <furrywolf> kenwood sold shielded cables with my amps, if I remember right.
[01:01:38] <renesis> little speakers, no?
[01:01:50] <furrywolf> renesis: stripping with a knife has the risk of nicking the inner conductor insulation.
[01:01:54] <furrywolf> no.
[01:01:58] <renesis> i know so i dont go through
[01:02:00] <furrywolf> monoblocks
[01:02:04] <renesis> and if it goes through, i redo it
[01:02:23] <furrywolf> right, you don't. but it's still a risk, and managers don't want to be inspecting everyone's strippings.
[01:02:32] <renesis> if i cut the outer insulation with anything, any method, im checking all the wires for nicks anyway
[01:02:41] <renesis> i pull apart the insulation with my fingers

[01:03:47] <renesis> xxcoder: yeah i dont get it really because i would think it would pick up the light
[01:03:59] <renesis> but i guess maybe LCD black is not black enough?
[01:04:03] <XXCoder> renesis: I suspect its color codes thats different
[01:04:24] <XXCoder> since lcds dont display same
[01:04:33] <renesis> you think it actually looks for white and not just light amplitude?
[01:04:39] <zeeshan> sometimes you cant see the nicks
[01:04:40] <zeeshan> lol
[01:04:52] <furrywolf> it has nothing to do with color.
[01:04:54] <furrywolf> just timing.
[01:05:01] <furrywolf> even I know that, and I don't even play games. lol
[01:05:02] <renesis> if you bend the wire youd see the nicks
[01:05:06] <zeeshan> you cant.
[01:05:10] <zeeshan> if its a small nick
[01:05:14] <renesis> furrywolf: so its refresh issue?

[01:06:09] <renesis> i always assumed it was a photodiode and a lens
[01:06:24] <XXCoder> "You can't. The way the zapper works is that it's actually a photo sensor (I think that's the right name for it)... the zapper doesn't shoot anything. It actually RECEIVES a beam of light transmitted from the TV. When you pull the trigger while playing a game, you notice a flash on the screen where everything but the target area is black. This is the light being beamed from your TV. If the photosensor sees the light coming up the
[01:06:24] <XXCoder> tube of the gun, it's a hit. LCD TVs don't output light like CRT TVs do."

[01:07:54] <zeeshan> has anyone closed the position loop with scales and steppers in linuxcnc?
[01:08:03] * zeeshan hasnt found any good links on google
[01:08:35] <zeeshan> i saw a youtube video on it
[01:08:48] <furrywolf> think about how analog tv works... the console is generating a raster image, and the tv is drawing it, at exactly the same time. if you aim a photosensor at a specific spot on the crt, when it's triggered, you just look at where you were drawing at the time.
[01:09:50] <renesis> okay so you would have to match latencies
[01:09:50] <furrywolf> there's no framebuffers, no delays other than speed-of-light and switching times of a few transistors.
[01:10:51] <renesis> i remember that white spot being there for a long time
[01:11:02] <renesis> prob like .1, .2 seconds, cant be that hard
[01:11:40] <furrywolf> hrmm. I just googled and found pages saying it works on simple light/dark, which isn't how I've always heard it was done.
[01:11:54] <renesis> its a photodiode
[01:12:00] <renesis> and a lens
[01:12:33] <renesis> it just looks for the white on black square, you could score hits by firing into the right kind of light
[01:12:42] <XXCoder> renesis: I really do wonder if it just needs is value adjustment
[01:12:50] <XXCoder> target #1, 2, so on
[01:12:54] <XXCoder> all has unique colors
[01:12:55] <furrywolf> ah, apparantly the SNES one works like I'm describing, using scanline timing, while the original NES one just used light/dark.
[01:13:08] <furrywolf> no, it has nothing to do with colors. they're all timing based.
[01:13:18] <renesis> SNES on used an IR sensor or something
[01:13:23] <renesis> the bazooka?
[01:13:28] <XXCoder> furrywolf: hmm ok

http://linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/3916-closed-loop-with-steppers
[01:14:00] <XXCoder> didnt know there was that accessory
[01:14:11] <zeeshan> you say "2. Dont expect good results trying to compensate for backlash with encoder feedback." -- why??
[01:14:23] <renesis> orange gun is weird
[01:14:25] <furrywolf> apparantly the original NES would black the screen, then draw one target white on the next frame, the next target white on the second frame, etc, and time how many frames it took before the gun saw white (if it ever did).
[01:14:27] <renesis> i had the gray gun
[01:14:53] <furrywolf> while the SNES and other systems work like I said, using the beam timing, not needing any special frames or anything else.
[01:15:02] <renesis> yeah white squares happened every time you pulled the trigger
[01:15:20] <XXCoder> ohhh
[01:15:26] <renesis> yeah but they need external sensors
[01:15:29] <XXCoder> wonder if amoled would work
[01:15:36] <XXCoder> because when black, it dont emit light
[01:15:38] <furrywolf> this means the NES guns should work just fine on LCDs, while the SNES and other systems will not.
[01:15:43] <XXCoder> but size is tiny

http://www.straightdope.com/columns/read/2304/in-nintendos-duck-hunt-how-does-the-tv-know-when-youve-hit-a-duck
[01:16:23] <furrywolf> it can't have anything to do with black levels, as that's already designed for by compensating for ambient light.
[01:17:07] <furrywolf> it could be that all LCD tvs still have too much lag between when the console sends a frame and when the panel is actually updated for it to correctly time it - it's still working on timing after all.
[01:17:26] <renesis> Since the Super Scope depends on the short persistence and scan pattern of CRT pixels, it will not function with modern displays (such as plasma screens or LCDs) that continuously light each pixel
[01:17:56] <XXCoder> renesis: supercope may theorically work with amoled
[01:18:25] <furrywolf> no design based on scan timing will work on any device with a framebuffer, period.
[01:18:47] <furrywolf> the only one with any chance of working would be the original NES gun, and only if the tv design updated the panel really quickly.

[01:24:32] <XXCoder> "First, it requires extremely precise timing between the trigger pull on the Zapper and the response on the screen."
[01:24:39] <XXCoder> furrywolf: yup youre right
[01:25:23] <furrywolf> this is how you design things with simple hardware. :)
[01:25:46] <furrywolf> sure, there's more robust designs... but they were impossible or impractical at the time.
[01:25:55] <XXCoder> wonder if rom can be hacked
[01:26:08] <XXCoder> so timing can be adjusted
[01:26:40] <furrywolf> probably, but it'd either need to be tuned per-tv, or would need to flash for a much longer period of time.
[01:27:13] <XXCoder> combation of slightly longer flash and adjustable timing
[01:27:17] <furrywolf> and would still only work for original NES guns, not any other system, as they used scan timing, which simply doesn't exist on anything with a framebuffer.
[01:27:54] <furrywolf> you could add a game start calibration screen, where you pulled the trigger to start the game, while it was displaying a test pattern that would time the tv.
[01:28:08] <XXCoder> thats pretty good
[01:28:39] <furrywolf> or you could emulate your games on some modern system with an lcd-compatible gun. :)
[01:28:48] <XXCoder> yeah

[01:39:43] <zeeshan> heres a quiz q
[01:40:00] <zeeshan> "what is the reason for reamers having an even number of teeth"
[01:40:36] <XXCoder> because odd may be prime and prime isnt good ;)
[01:40:40] <zeeshan> hehe
[01:40:43] <XXCoder> (2 is only even prime)
[01:40:46] <zeeshan> its actually a non technical reason
[01:40:56] <zeeshan> so you can measure the diameter of the reamer
[01:41:02] <XXCoder> makes sense
[01:41:02] <zeeshan> since it's used for precise holes.
[01:41:03] <zeeshan> haha
[01:41:35] <zeeshan> this course i was getting
[01:41:51] <zeeshan> and enjoying , till he started doing all the heat transfer partial differential equations
[01:41:57] <zeeshan> when we got to the thermal section of metal cutting
[01:42:05] <zeeshan> that stuff is intense
[01:42:16] <furrywolf> that seems like a poor process. a standard split mold would result in much faster production, not be full of voids, and wouldn't require carefully scraping off sharp glass, just a bit of flash removal.
[01:42:31] <furrywolf> you could make one mold with a dozen bulbs...
[01:42:56] <furrywolf> hell, the bulb shape is probably tapered enough you could just use a one-piece silicone mold and not even need to clean up the final product.
[01:42:57] <XXCoder> it keeps orginial metal socket at bottom
[01:43:08] <furrywolf> you can mold it into the metal socket. :P
[01:43:42] <XXCoder> Guess so lol
[01:44:15] <furrywolf> also, as a functional issue, the bulb shape is rounded enough it probably doesn't make a good hook, especially being mirror finish.
[01:45:58] <furrywolf> but, you know, art people. :P
[01:46:10] <XXCoder> Right on that article, "one question, how do i make it?"
[01:46:12] <XXCoder> uhhh
[01:46:18] <furrywolf> lol
[01:46:39] <furrywolf> my guess is they didn't realize it was multiple pages.
[01:46:54] <XXCoder> yeah. aloew menioned same thing as you did lol
[01:46:58] <XXCoder> multipart mold
[01:47:10] <furrywolf> because, presumably to show lots of ads I don't see due to having adblockplus installed, many websites like breaking things up into a bunch of small pages.
[01:47:35] <XXCoder> there is mod that combines into one page

[01:48:26] <XXCoder> what ya think
http://www.instructables.com/id/How-to-Build-a-Polished-Concrete-Desk/
[01:48:48] <furrywolf> I think concrete sucks.
[01:49:46] <XXCoder> wtf guy added fiber cables into concerete
[01:49:57] <XXCoder> and glasses stuff like beads?
[01:50:37] <furrywolf> make it decorative

[03:49:49] <Cromaglious> 0.001
[03:50:25] <XXCoder> wonder why
[03:51:14] <Cromaglious> probably using single pression internally

[03:52:47] <XXCoder> yo
[03:52:49] <Cromaglious> 45 tooth gear, 2" across
[03:53:19] <Cromaglious> using 1/16 microstep to get the steps
[03:53:41] <Cromaglious> 20320 per inch
[03:57:23] <XXCoder> pretty fine
[03:58:22] <furrywolf> microstepping doesn't translate directly into resolution... I have some drivers that'll do 256 microsteps, and I'm willing to bet there's absolutely no movement of the table between most of them...
[03:58:46] <zeeshan> yhep
[03:58:50] <zeeshan> and i checked this on my lathe too
[03:58:53] <zeeshan> microstepping is bs
[03:59:16] <Cromaglious> backlash counts too
[03:59:17] <zeeshan> im on 1/4 microstep and that works out to like .0001 resolution
[03:59:20] <zeeshan> it doesnt move
[03:59:31] <zeeshan> with 0 backlash (on my x-axis)
[03:59:40] <zeeshan> and if youre moving in the same direction, there is no backlash
[03:59:42] <zeeshan> and it doesnt mean
[03:59:50] <zeeshan> smallest itll move is 0.0005"
[04:00:08] <XXCoder> .0005 is pretty decent and work for most jobs
[04:00:56] <furrywolf> that said, when I turn up my microstepping, it runs much quieter and smoother...
[04:01:04] <Cromaglious> I see the stepper move, but if there is backlash it doesn't move and if it's going in the same direction I may see carriage movement
[04:01:07] <zeeshan> but you lose holding torque
[04:01:13] <zeeshan> i think 1/4 microstep is pretty good
[04:01:29] <zeeshan> you're at 77.77% holding torque i believe
[04:01:38] <furrywolf> I decided on 10 microsteps. it limits my top speed slightly, but 5 is a lot noisier.
[04:01:47] <furrywolf> right, and I have absolutely no shortage of holding torque.
[04:02:16] -!- iceberg303 has quit [Read error: Connection reset by peer]
[04:02:24] <furrywolf> I might actually reduce the motor current, as right now Z rips the bushings out if you run it all the way up...
[04:02:28] <Cromaglious> problem with sketchucam is if it's too small it will not see it and ignore it.
[04:02:39] <furrywolf> and they're a pain in the neck to readjust.
[04:02:41] <zeeshan> what kind of silly cam program is
[04:02:41] <zeeshan> haha

[04:04:36] <furrywolf> holding torque doesn't tend to be the limit... fast movement is the problem.
[04:05:09] <furrywolf> you don't actually need ANY holding torque on a mill with acme leadscrews. heh.
[04:05:24] <zeeshan> yea well i dont have that :p
[04:06:46] <furrywolf> I have enough low-end torque to damage my mill, so I'm not worried about microstepping losing some of it. heh.
[04:07:02] <zeeshan> what size steppers
[04:07:20] <furrywolf> I'd like more top speed, but too much work. I'd need to re-gear (it has a 2:1 belt reduction stock) or do expensive upgrades.
[04:07:25] <furrywolf> nema34, 944ozin.
[04:07:29] <zeeshan> pretty big :)
[04:07:38] <furrywolf> or maybe it was 960. I don't remember which spec sheet goes with what anymore
[04:07:45] <zeeshan> im gettin about 100 ipm out of the 1200 oz-in
[04:07:53] <zeeshan> i thought it was bad, but apparently thats where its supposed to be
[04:08:35] <XXCoder> 110 n.cm
[04:08:37] <furrywolf> I get 1.8in/s at reasonable acceleration, higher if I set the acceleration slow. linuxcnc needs some acceleration that depends on current velocity, rather than fixed.
[04:08:56] <furrywolf> I think I have the limit set at 1.2in/s now, due to hitting my step limit.
[04:09:33] <XXCoder> ah 155.773 oz/in
[04:09:45] <furrywolf> the stand the mill is on resonates badly around 1.5in/sec. I'd need to remove the handwheels or build perfectly balanced ones.
[04:09:45] <XXCoder> heh mines weak compared to your beasts
[04:09:59] <zeeshan> XXCoder: but i bet yours can move at 600 ipm
[04:10:01] <XXCoder> make base more beefy?
[04:10:02] <zeeshan> on the same setup :)
[04:10:10] <furrywolf> my motors weigh about ten pounds each, and are running at 8.5A/phase off a 56V supply.
[04:10:15] <Cromaglious> I can do .33"/s
[04:10:50] <zeeshan> furrywolf: think if i up the current
[04:10:53] <furrywolf> I might re-transformer the supply for 65ish volts.
[04:10:53] <zeeshan> i can get more speed out of it?
[04:10:55] <furrywolf> no
[04:11:14] <furrywolf> to get more speed, you up the voltage, not the current. it only ever sees the current limit at stop or near stop.
[04:11:28] <Cromaglious> then again I'm running a yoocnc piece of crap
[04:11:29] <zeeshan> i forget the torque formula
[04:11:32] <furrywolf> once you're moving, it never gets near the current limit.
[04:11:34] <zeeshan> that relates to vi
[04:12:02] <zeeshan> well im already maxed out then :p
[04:12:07] <zeeshan> the drives i think handle 80vdc
[04:12:10] <zeeshan> and im running a 65vdc supply
[04:12:14] <zeeshan> kinda near the limits
[04:12:20] <furrywolf> doubling voltage doubles torque at a given speed, or gives you more speed (how much more your motors have a little graph to show) at the same torque.
[04:12:45] <furrywolf> yeah, mine are rated for 80V too. I went with 56V because I found a transformer cheap, but I might go up to 65V.
[04:13:03] <furrywolf> my caps are 75V, so I need to stay below that with some margin for braking.
[04:13:14] <Cromaglious> well going from a tb6560 to a tb6600 I can go from 24v to 45v
[04:13:42] <furrywolf> Cromaglious: be warned many of those chinese boards fry above 24V, regardless of ratings. google the board first.
[04:14:00] <Cromaglious> they're suggesting 36v for the tb6600
[04:15:07] <furrywolf> don't google the toshiba chip. google the board.
[04:15:37] <XXCoder> chip may be fine but other stuff may not be
[04:15:59] <furrywolf> I've seen several mentions of those boards catastrophically failing even when they're rated for higher voltages.

[04:17:29] <XXCoder> cnc sensor?
[04:17:32] <zeeshan> theres gotta be a formula for maximum stepper speed
[04:17:33] <XXCoder> to find x,y so on?
[04:17:40] <zeeshan> based on voltage and inductance
[04:17:40] -!- FinboySlick has quit [Quit: Leaving.]
[04:17:46] <zeeshan> and maybe resistance
[04:18:13] <furrywolf> zeeshan: no. there's a graph in the datasheet for the motor.
[04:18:22] <zeeshan> i dont believe you
[04:18:57] <furrywolf> Cromaglious: again, the CHIP is rated for higher voltage, and the board may be RATED for a higher voltage, but that doesn't mean it actually WORKS at a higher voltage, because the boards are CRAP.
[04:19:03] -!- anth0ny_ has quit [Quit: anth0ny_]
[04:19:09] <Cromaglious> it's a induction youch probe, still figuring them out
[04:19:36] <furrywolf> showing me a picture of the heat sink won't change this. :P
[04:19:44] <toastydeath> induction probes are pretty simple devices
[04:19:48] <zeeshan> rev/s = [V/(L*2*I_max)] / (steps/rev)
[04:20:01] <zeeshan> so for my motor that works out to 4.17rev/s
[04:20:09] <Cromaglious> yeah, think I'm gonna have to get a ardunio to read them
[04:20:11] <toastydeath> http://www.efunda.com/designstandards/sensors/lvdt/images/lvdt_how.gif
[04:20:21] <zeeshan> 250 rpm
[04:20:30] <toastydeath> you can read them with an oscilloscope
[04:20:35] <toastydeath> as long as you have a driver signal
[04:20:52] <toastydeath> (100khz sine wave from a signal generator works)
[04:21:09] <XXCoder> I wonder if my board supports contact zero finding
[04:21:16] <XXCoder> like this
http://cdn.instructables.com/FF6/KZD9/HL946T8F/FF6KZD9HL946T8F.LARGE.jpg
[04:21:37] <Cromaglious> well I want a touch sensor for the cnc, so I'll probably get a nano to read it and output a go/no go signal
[04:21:37] <zeeshan> haha
[04:22:57] <furrywolf> that's just a generic input, the board doesn't need to do anything special. (and that one isn't even an input - it just lights the LED!)
[04:23:02] <Cromaglious> it works, whatch laughing at?
[04:23:42] <XXCoder> Cromaglious: you can abuse touch sensor for this
http://hackaday.com/2014/07/31/milling-curved-objects-with-a-g-code-ripper/
[04:23:46] <zeeshan> clearly this number is way off
[04:23:53] <zeeshan> 250 rpm * .196 in /rev
[04:24:03] <zeeshan> apparently im limited to a max of 49 ipm
[04:24:06] <zeeshan> im breaking physics
[04:24:20] <XXCoder> blinding fast lol
[04:24:25] <XXCoder> ya sure using right units?
[04:24:28] <zeeshan> i thinkso
[04:24:28] <furrywolf> what part of "no. there's a graph in the datasheet for the motor." is difficult?
[04:24:32] <zeeshan> 5mm pitch
[04:24:38] <zeeshan> which is .196 in / rev
[04:24:50] <zeeshan> furrywolf: there is actual graph
[04:24:52] <zeeshan> and theoretical
[04:25:02] <zeeshan> when there is no graph, you need to rely on theoretical to get you close
[04:25:09] <furrywolf> there's various rules of thumb and guesstimates, and they're not replacements for test results.
[04:25:13] <zeeshan> in this case its off by 50 ipm :)
[04:25:22] <zeeshan> obviously
[04:25:25] -!- FreezingAlt has quit [Ping timeout: 250 seconds]
[04:25:28] <zeeshan> but you need test results to begin with
[04:25:32] <furrywolf> what brand/model are your motors?
[04:25:38] <zeeshan> automation technologies 1200 oz-in
[04:25:52] <Cromaglious> XXCoder, that is seriously kewlness!
[04:26:10] <furrywolf> that's a torque rating, not a model. a model is generally a long ugly alphanumeric sequence.
[04:26:12] <XXCoder> yeah. I want to design something
[04:26:38] <XXCoder> did you see bat video?
[04:26:47] <zeeshan> KL34H2120-60-4B
[04:28:27] <Cromaglious> not yet
[04:28:43] <XXCoder> it dont seem to use probe so dunno why its there but cool
[04:29:01] <furrywolf> hrmm, look like rebranded chinese something, might need to figure out actual manufacturer...
[04:29:05] <Cromaglious> yeah, the engraving looked flat on the bottom of the bat
[04:29:19] <furrywolf> next time get motors from a brand. :)
[04:29:26] <zeeshan> http://www.kelinginc.net/KL34H2120-60-4AT.pdf
[04:29:28] <zeeshan> this might be it.
[04:31:18] <furrywolf> it's probably similar, yes.
[04:31:29] <furrywolf> note that's series wound, you've hopefully wired yours for parallel.
[04:31:31] <zeeshan> so i guess 6000 / 200
[04:31:36] <zeeshan> yea mine are paralle
[04:31:42] <furrywolf> which does change the curve slightly...
[04:32:07] <furrywolf> (well, it changes it substantially - two times I think - but it also tweaks the shape slightly)
[04:32:44] <zeeshan> a little bit less speed with bipolar parallel
[04:32:48] <zeeshan> but much more torque
[04:33:14] <furrywolf> but your limiting speed is where you run out of torque, so... :P

[04:33:51] <furrywolf> it may have a lower nothing-attached-to-the-shaft speed, but it will probably have a higher top speed with a load.
[04:34:28] <furrywolf> find a graph for another motor that shows both, and note how the parallel curve is above the series curve almost until it hits 0 torque.

[04:34:54] <zeeshan> 6000 pulse/s * 1/200 rev/pulse * 60 s/min
[04:35:09] <zeeshan> 1800 RPM
[04:35:29] <zeeshan> *.196 in/rev = 352.8 ipm
[04:35:36] <zeeshan> so im at 1/3 that almost.
[04:36:03] <furrywolf> first, your graph is at 100V, while you're not running 100V, so you have a factor there.
[04:36:10] <zeeshan> thats true
[04:36:49] <zeeshan> assuming linear relationship (doubt it)
[04:37:09] <zeeshan> 0.35 * 352.8ipm =123 ipm
[04:37:09] <zeeshan> wow
[04:37:12] <zeeshan> thats pretty AWESOME
[04:37:17] <furrywolf> also, you can't do that without knowing how much torque you need. both to overcome friction on the machine, and to accelerate the weight of the screws, table, vise, part, etc.
[04:37:23] <zeeshan> cause i can hit 120 ipm , but ive got it down to 100 ipm for a buffer
[04:37:33] <zeeshan> i cant believe voltage makes that much of a diff.
[04:37:43] <furrywolf> if you set your acceleration down reallllly slow, you can get the speed up a lot higher...
[04:37:48] <zeeshan> ive tried
[04:37:50] <zeeshan> it doesnt effect it really
[04:38:00] <zeeshan> its set to 10in/s^2
[04:38:02] <furrywolf> voltage is roughly linear. 65v is about .65 the torque of 100v.
[04:38:20] <zeeshan> whoops not .35
[04:38:20] <zeeshan> duh
[04:38:31] <zeeshan> okay thats 229 ipm then
[04:38:40] <zeeshan> so it drops by over 100 ipm
[04:38:55] <zeeshan> need 100vac drives!
[04:39:02] <furrywolf> also, those are half-step pulses, so you need 1/400 rev/pulse.
[04:39:17] <Connor> zeeshan: You ever get your ballscrew figured out ?
[04:39:23] <Connor> why it was so hard to turn ?
[04:39:34] <zeeshan> connor too much preload on the fixed end
[04:40:07] <furrywolf> so 229/2 is 115ish...
[04:40:19] <zeeshan> furrywolf: pretty damn close to my actual number
[04:40:39] <furrywolf> now, you have it in parallel, which gives you double the torque, but a lower top speed... but they do tend to hit the axis around the same point.
[04:40:40] <zeeshan> so if i went to a 80v supply
[04:40:40] <Connor> Cool.. so you getting better speed now ?
[04:40:52] <zeeshan> Connor: back to what it was w/ the single ball nut
[04:40:59] <Connor> Good.
[04:41:02] <zeeshan> 120 ipm, but downgraded to 100
[04:41:04] <furrywolf> see, when you go by actual data, you get numbers that resemble what actually happens. :P
[04:41:06] <zeeshan> for safety
[04:41:14] <zeeshan> furrywolf: i know :P
[04:41:17] <zeeshan> test data ftw
[04:41:26] <zeeshan> theoretical should get you close though
[04:41:37] <zeeshan> but unfortunately i havent done much electrical theory
[04:41:40] <zeeshan> so i cant really comment on that
[04:41:44] <Cromaglious> http://www.youtube.com/watch?v=qGyMBkYgQsQ he really need to cnc this
[04:41:51] <furrywolf> there is no theoretical, there's only rough rules of thumb. the motor construction makes a huge difference.
[04:42:40] <furrywolf> there's steppers that'll spin tens of thousands of rpm...
[04:43:05] <zeeshan> man apparently that kl11078 took in ac
[04:43:09] <furrywolf> heh, my drivers even came with a warning that for certain models of stepper, the driver can drive them fast enough to burn the ball bearings.
[04:43:11] <zeeshan> so youdidnt need to run a seperate power supply
[04:43:12] <zeeshan> ~!!!
[04:43:48] <furrywolf> by running it in parallel, you get similar torque at 50V to what they measured in series at 100V.
[04:43:53] <zeeshan> this thing:
http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers/kl-11080-stepper-drive
[04:44:03] <furrywolf> you're getting more torque than the graph shows, not less
[04:44:24] <zeeshan> yea
[04:44:34] <zeeshan> i want moar speed though
[04:44:40] <zeeshan> need more voltage
[04:44:50] <zeeshan> fak if this thing ran 250 ipm
[04:44:52] <zeeshan> id be so happy
[04:44:59] <furrywolf> servos. :P
[04:45:05] <zeeshan> w/ steppers :P
[04:45:10] <furrywolf> steppers are not the technology of choice for high speed.
[04:45:14] <XXCoder> 16x gearing heh
[04:45:21] <XXCoder> much less precision :P
[04:45:26] <zeeshan> but we just saw at 6000 pps
[04:45:32] <zeeshan> it can do 350~ ipm
[04:45:39] <zeeshan> i should be able to do 250
[04:45:48] <furrywolf> gearing might not even help, unless you're gearing it down a lot, and want to undo that.
[04:45:50] <zeeshan> XXCoder: yea the damn tradeoff
[04:45:55] <furrywolf> <furrywolf> also, those are half-step pulses, so you need 1/400 rev/pulse.
[04:46:07] <furrywolf> note the graph explicitly says halfstep.
[04:46:14] <zeeshan> oh so 175 ipm max.
[04:46:21] <zeeshan> :-(
[04:46:27] * zeeshan goes back and sits in the corner
[04:46:43] <furrywolf> right. and that's max rpm with nothing on the shaft. you have a machine on the shaft, with friction and inertia.
[04:46:44] <zeeshan> honestly, if i were to go servo
[04:46:46] <zeeshan> id just buy another lathe
[04:46:48] <zeeshan> and sell this one
[04:47:10] <zeeshan> something with a spindle that can go to 6000 rpm at least
[04:47:23] <furrywolf> I got my steppers up to something like 5in/sec spinning a bit of electrical tape stuck to the end of the shaft. that doesn't mean the machine does that. :P
[04:47:33] <zeeshan> yes
[04:47:44] <XXCoder> heh yea it was real fast when I was testing
[04:48:18] <furrywolf> seems to me like your machine is operating about where you'd expect given the specs of the motors.
[04:48:48] <zeeshan> meh 100 ipm is ok
[04:48:51] <zeeshan> it gets the job done
[04:49:01] <zeeshan> ill finish making an enclosure for it
[04:49:02] <zeeshan> and be happy :)
[04:49:47] <zeeshan> its so hard to not always want more
[04:49:50] <zeeshan> damn human nature.
[04:50:35] <furrywolf> yeah, I have mine running around 100ipm too.
[04:51:03] <zeeshan> i think at speeds of 250 ipm
[04:51:09] <zeeshan> central lubrication becomes necessary
[04:51:32] <furrywolf> well, 80. need to deal with the non-balanced (doesn't even have a counterweight) handwheels making the machine walk around the floor problem to set it back higher.
[04:51:45] <zeeshan> bolt it down
[04:51:47] <zeeshan> :P
[04:51:54] <zeeshan> why do you still have handwheels?

[08:03:58] <Deejay> 9am here ;)
[08:04:24] <Jymmm> archivist: Wow, new cnc porn =)
[08:04:48] <XXCoder1> What is guy making archivist
[08:04:55] <XXCoder1> some air bearing thingy he was holding?
[08:05:22] <Jymmm> a 1 micron cnc lathe/grinder
[08:05:52] <XXCoder1> dang
[08:06:07] <XXCoder1> .001 tol would be very rough compared to that
[08:07:16] <archivist> he mentioned other method of lapping, I did this on a piston and bore, not easy
[08:08:06] <XXCoder1> interesting, grinder on lathe
[08:08:18] <XXCoder1> I notice grinder tend to make VERY accurate parts
[08:08:25] amnesic_away is now known as amnesic
[08:10:50] <RifRaf> that lathe was awesome
[08:11:05] <Jymmm> Video downloaded =)
[08:11:28] <XXCoder1> wish autocaptions was better but I bet its awesome video
[08:11:43] <XXCoder1> very good teaching videos is worth more than gold
[08:11:55] <RifRaf> yep spent the last 40 hours watching them here :)
[08:12:13] <XXCoder1> Jymmm: using youtube center?
[08:12:24] <Jymmm> XXCoder1: He had a bit of a thick accent. Yep =)
[08:12:54] <XXCoder1> Jy, old videos tend to be very surpising good
[08:13:03] <XXCoder1> goverment ones expecially
[08:13:21] <XXCoder1> its almost normal caption quality other than weird wrong words for techinical words
[08:13:39] <Jymmm> XXCoder1: I don't trust bookmarks anymore, got burned too many times.
[08:13:55] <XXCoder1> bookmarks?
[08:14:17] <Jymmm> XXCoder1: where you bookmark urls (favorites)
[08:14:37] <XXCoder1> ahh yea thought it was direct reply to youtube center
[08:14:47] <XXCoder1> its addon that allow me to do stuff
[08:14:51] <XXCoder1> like no more ads and download
[08:15:02] <Jymmm> Well, that too. But I use google bookmarks for that.
[08:16:46] <Jymmm> Just be careful, it's case sensative
[08:17:54] <Jymmm> I DO like that he said he gets his shit cheap off ebay, even though in the background you see craploads of TE =)

[08:30:07] <XXCoder1> interesting
[08:30:27] <XXCoder1> I guess very hard metals need more weight
[08:30:42] <archivist> 20 years ago I needed one, but at that price it was worth fetching to play and learn

[13:43:21] <Swapper> anyone knows if its prohibitively expensive to get stuff laser/plasma cut ?
[13:43:35] <Swapper> plain sheetmetal 0.7mm
[13:44:36] -!- mozmck [mozmck!~moses@67.210.159.245] has joined #linuxcnc
[13:44:45] <archivist> not that costly, mostly up against setup/minimum order
[13:45:43] <archivist> I have a local company and last time I went in the minimum order was £100
[13:46:32] <_methods> our minimum is $75
[13:47:10] <Swapper> _methods: and that would make it possible to get some parts cut in that price?
[13:47:24] <_methods> sure
[13:47:36] <_methods> especially if you have dxf/models
[13:47:44] <Swapper> im planning on cutting out some parts for a coolant tank and chip tray about 2 square meters of 0.7 sheetmetal
[13:47:53] <archivist> there is often a setup cost, read in your file, check it, load machine etc
[13:47:55] <Swapper> i have all in cad
[13:48:04] <_methods> you just want them cut?
[13:48:08] <Swapper> yea
[13:48:19] <_methods> .7 is thin
[13:48:22] <Swapper> i have sheet break and welder my self
[13:48:26] <_methods> k
[13:48:37] <Swapper> cant break more than that
[13:48:39] <_methods> yeah if you walk into any local shop with drawings
[13:48:40] <archivist> seems thin for the volume
[13:48:43] <_methods> they'll be happy
[13:49:01] <_methods> it's when you walk in with a napkin that it can get expensive
[13:49:02] <Swapper> i reccon it will be stiffer when i weld it up
[13:49:30] <Swapper> is a upgrade from a plastic container
[13:49:32] <Swapper> so...
[13:49:32] <archivist> its the wall bulging under the weight
[13:50:06] <archivist> we used to send in a dxf
[13:50:25] <_methods> if you go there with the material and the drawings in dxf format it will just be a time thing for them
[13:50:41] <_methods> you can get it done for probably around $100
[13:50:41] <Swapper> id like to get the mats from them
[13:50:52] <Swapper> that seems what i where thinking
[13:51:09] <_methods> yeah if it's steel that's dirt cheap anyways
[13:51:21] <_methods> a 5x10 sheet of that would probably be like $60
[13:51:27] <Swapper> yea plain un treeted sheet metal
[13:52:26] <_methods> how big are teh parts?
[13:52:57] <Swapper> the biggest is 600mm long and about 400mm wide
[13:53:18] <Swapper> think ill get it all in on a 2x1m sheet
[13:53:39] <Swapper> 0.7 is tig weldable right
[13:53:40] <Swapper> ?
[13:53:46] <Swapper> will it warp like crazy ?
[13:53:48] <_methods> yeah if you can tig
[13:54:11] <_methods> i wouldn't want to try and mig thin stuff like that
[13:54:22] <Swapper> nah only have tig
[13:54:56] <archivist> bit like gluing car body tin
[13:55:16] <_methods> yeah it should tig just fine and i'm sure a good welder could mig it
[13:55:29] <_methods> but i'd blow so many holes in it
[13:55:41] <_methods> i'm a hurrible welder
[13:56:00] <Swapper> atleast ill learn to tig better doin it :)
[13:56:11] <Swapper> as long as its not aluminum....
[13:56:12] <_methods> practice on coke cans hehe
[13:56:12] <Swapper> hate that
[13:56:52] <Swapper> stainless and normal sheet metal i have done some on and thats fine
[13:56:53] <archivist> rusty car tin sorts out the skilled from me
[13:57:12] <Swapper> stainless warps a lot and scales but that dosnt matter
[13:57:17] <_methods> yeah i tried to weld a rust muffler one time...........
[13:57:25] <_methods> i had to call my buddy who is a real welder lol
[13:57:55] <archivist> I am trained but on thick mig and stick
[13:57:57] <_methods> s/rust/rusty
[13:57:59] <Swapper> cleanlines is real differance when tig ing
[13:59:23] <Swapper> asked a local company and they take 64$ in "setup" for the laser
[13:59:34] <Swapper> + seconds / minutes per part
[13:59:36] <Swapper> in cutting time
[13:59:41] <Swapper> + materials
[14:00:05] <_methods> that sounds about right
[14:00:24] <_methods> we're pretty low at $75 min charge
[14:00:33] <_methods> most shops are $100+
[14:00:52] <Swapper> might get the parts for 200-250$
[14:00:53] <Swapper> humz
[14:01:17] <_methods> well with that thin of material you can lay it out and use tin snips
[14:01:29] <_methods> or a jig saw
[14:01:32] <Swapper> yea, i do have a plasma
[14:01:33] <archivist> or just get it cropped

[14:50:30] <ssi> I don't really need that though, since there's no cutting force
[14:50:34] <ssi> straight belt drive is fine
[14:50:50] <Swapper> quite low backlash is the advantage

[15:27:19] <_methods> i know why those rollers in the middle won't work
[15:27:34] <_methods> i got to mess with some this weekend
[15:27:40] <ssi> oh?
[15:27:47] <_methods> they rock in the track
[15:27:55] <ssi> blah
[15:27:57] <_methods> there's a lot of play that way vs av
[15:28:01] <_methods> V
[15:28:13] <_methods> yeah
[15:28:47] <_methods> but i don't know if they had enough tension on them

[15:29:49] <ssi> that doesn't make me happy
[15:30:00] <_methods> no sorry i found out on friday
[15:30:03] <_methods> i forgot to tell you
[15:30:12] <furrywolf> I want to make a plasma table one of these days, but I'm going to use aircraft cable to move it, not belts.
[15:30:22] -!- nerdfiles has quit [Ping timeout: 240 seconds]
[15:30:27] <_methods> or found out on saturday
[15:30:55] <_methods> i think if you added a couple more wheels it may fix it though
[15:31:01] <_methods> but then that adds to the bearing count
[15:31:11] <ssi> how many wheels did you use
[15:31:14] <_methods> or add a bearing that rides on the extrusion
[15:31:18] <ssi> bearings are cheap
[15:31:29] <_methods> the one i was messing with was using 4 wheels
[15:31:37] <_methods> like your current design
[15:31:52] <_methods> so i think if you add a bearing to stabilize
[15:31:56] <_methods> that would fix it
[15:32:23] <_methods> just add 1 on top and one on bottom to increase bearing surface
[15:32:39] <_methods> have it run on the flat of the extrusion
[15:33:21] <_methods> you could probably get away with block of uhmw also
[15:33:29] <ssi> that would be much easier
[15:33:31] <_methods> or something equally "slippery"
[15:33:42] <_methods> just something to keep it from rocking
[15:33:58] <ssi> adding a bearing perpendicular to the carriage plate is going to be a hassle
[15:34:02] <ssi> I assume that's what you mean
[15:34:05] <_methods> yeah
[15:34:40] <_methods> well i suggest you just make up a carriage and try it in the extrusion
[15:34:46] <_methods> just so you can see what i'm talkin about
[15:35:00] <ssi> yeah
[15:35:11] <ssi> that table is a LOT of money in extrusion
[15:35:15] <_methods> yeah
[15:35:15] <ssi> like $800 or so
[15:35:38] <_methods> that's why i just plan on doing mine out of tubing
[15:35:46] <_methods> i'm a cheap bastard
[15:35:51] <ssi> I thought about it
[15:35:55] <ssi> but tubing doesn't make it that much cheaper
[15:35:59] <ssi> and it's a lot more difficult to get it right
[15:36:00] <_methods> really?
[15:36:34] <ssi> I priced out 2x4" rect tube, 1/8" wall
[15:36:47] <ssi> 10' sticks are about $50 apiece
[15:36:52] amnesic is now known as amnesic_away
[15:36:58] <_methods> 10'?
[15:37:08] <_methods> normally they are 20'
[15:37:15] <ssi> yeah I know
[15:37:17] <_methods> are they charging you to cut them ?
[15:37:19] <ssi> I just quoted a lenght and qty
[15:37:20] <ssi> no
[15:37:34] <ssi> I could probably get it cheaper
[15:37:36] <_methods> yeah
[15:37:44] <_methods> i would think $50 for 20'
[15:37:48] <_methods> but i don't know
[15:37:52] <_methods> i'd have to get quotes
[15:38:12] <furrywolf> ssi: what're you building?
[15:38:20] <ssi> laser table
[15:38:37] <_methods> but i think the alum extrusion is perfect for laser
[15:38:42] <_methods> it's lighter weight
[15:38:48] <ssi> and easier to keep it square
[15:38:48] <_methods> and easier to work with
[15:38:51] <furrywolf> I think I'll stick with plasma.
[15:38:51] <_methods> yeah
[15:39:00] <furrywolf> I'll be using all angle iron, no fancy aluminum.
[15:39:11] <ssi> I built my plasma table out of 3/16" wall 2x4 steel
[15:39:47] <furrywolf> I could use box, but the scrapyard always has a much better selection of angle.
[15:41:18] <ssi> I haven't been able to find a good metal supplier in atlanta actually
[15:41:24] <ssi> I don't think anyone here makes anything
[15:41:33] <_methods> heheh
[15:41:45] <furrywolf> it's getting that way here too... there's only one place left to buy metal, the others closed.
[15:42:40] <_methods> hell no one wants to be around that damn atl traffic
[15:42:43] <_methods> i'd move the hell out too
[15:43:14] <ssi> if no one wanted to be here cause traffic, there wouldn't be anymore traffic! :D
[15:43:47] <furrywolf> my plan is to use angle or box pointy-side-up and gate wheels rolling on it, and move it around with aircraft cable. cheap, sturdy...
[15:44:07] <_methods> heheh
[15:44:13] <_methods> this is true
[15:46:22] <furrywolf> plasma is dirty and messy, and anything delicate will be destroyed...
[15:46:58] <_methods> hell traffic is so bad there you had to buy airplanes
[15:48:08] <ssi> I'm still trying to figure out a way to commute to work by air
[15:48:15] <_methods> cannon
[15:48:17] <_methods> lol
[15:48:50] <_methods> i was looking at making a gyrocopter
[15:49:02] <ssi> haha I would love to fly a gyrocopter
[15:49:11] <ssi> dan thinks I'm nuts for it, and he'll fly almost anything
[15:49:15] <_methods> hell yeah i'm suprised more people don't use them
[15:49:23] <_methods> are they that dangerous?
[15:49:30] <ssi> when I went down to fl to pick up that pitts on tuesday, this was there
[15:49:31] <ssi> https://pbs.twimg.com/media/B__IDpUWoAArLTz.jpg:large
[15:49:36] <ssi> yeah they're pretty damn dangerous
[15:49:39] <furrywolf> I've yet to see why they're better than a proper copter...
[15:49:49] <ssi> they're FAR cheaper
[15:50:01] <_methods> yeah money
[15:50:12] <_methods> short takeoff and land
[15:50:22] <ssi> haha last night he and I were driving up to kennesaw and there was a guy pulling a trailer with a gyro on it
[15:50:33] <furrywolf> why? a swashplate and some heim joints doesn't add much to the cost, and you already have a second prop anyway for a tail...
[15:50:34] <ssi> and we pulled up next to him and dan rolls down the window and yelss "HEY! NICE DEATHTRAP"
[15:50:52] <_methods> damn i had no idea that they were that dangerous
[15:51:12] <ssi> I don't think they're as bad as he makes them sound
[15:51:17] <_methods> i guess that is a lot of spinning shit right next to your unprotected body
[15:51:32] <ssi> honestly I've seen a lot of gyroplane wreck videos
[15:51:36] <ssi> and people tend to walk away from them
[15:51:38] <ssi> but they LOOK nasty
[15:52:00] <_methods> yeah i thought the great thinga bout them was that if the engine crapped out on you you just autorotated down
[15:52:04] <ssi> you do
[15:52:07] * furrywolf doesn't see why a helicopter involves significantly more money than a gyrocopter
[15:52:12] <_methods> since they're basically in an autorotating state already
[15:52:13] <ssi> furrywolf: go build one
[15:52:56] <furrywolf> I have an r/c one, does that count? :P
[15:53:13] <ssi> _methods: if you're not gentle on them in pitch, you can stall the rotor, and even stall it so bad that it goes negative and flops into the prop
[15:53:19] <furrywolf> (and a real one. made of aluminum, with an engine. none of this plastic and batteries stuff...)
[15:53:20] <ssi> that's a Bad Day
[15:53:48] <ssi> furrywolf: well I dunno about you, but I have a "real one" too, and mine cost as much to build as a gyroplane that you can put your ass in :)
[15:54:16] <furrywolf> you spent real money on r/c stuff? heh
[15:55:02] <ssi> you should go build yourself a homebuilt helicopter

[15:55:22] <ssi> oh I'm sure
[15:55:31] <archivist> death wish 9
[15:55:32] <ssi> honestly I'd much rather have a subie in a helicopter than an airplane
[15:55:35] <ssi> it couples much better
[15:55:48] <ssi> helicopters need a drive train either way
[15:56:18] <furrywolf> hrmm, what's a good rpm for a heli rotor?
[15:56:26] <ssi> depends on the diameter
[15:56:32] <ssi> robinsons run around 200rpm I think
[15:56:50] <furrywolf> that's a lot of reduction.
[15:56:52] <ssi> I don't know a ton about rotor aerodynamics, but at first blush I'd guess you want an rpm to maintain something like mach .85-.90 at the tips
[15:58:03] <furrywolf> google suggests 450rpm is common on a light helicopter. (from two search results)
[15:58:20] <furrywolf> so figure you need 10:1..
[15:58:28] <ssi> you need a governor too
[15:58:44] <jdh> like wisconsin?
[15:59:02] <ssi> shoot for something like 650fps tip speed

[15:59:34] <furrywolf> so strip everything but 2nd gear out of a subaru transaxle, pin it in 2nd, rotate the bellhousing 90 degrees, replace the diff with a spool, and presto, you have 10:1 AND a shaft pointing upwards. :)
[15:59:50] <ssi> what's that all gonna weigh
[16:00:02] <furrywolf> dunno. :P
[16:00:28] <ssi> remember you probably want this whole aircraft to weigh somewhere around 700lb
[16:01:01] <furrywolf> I bet you can use the stock cruise control actuator as a governor, too - it gets its input signal from the tranny...
[16:01:23] <furrywolf> just get the rpm where you want it and hit cruise. :)
[16:02:04] <furrywolf> heh, and the 4x4 transaxle even has another shaft sticking out the back to run your tail rotor off...
[16:02:25] <skunkworks> isn't there big discussion about using automotive engines in airplanes? Like - you will probably crash.
[16:02:38] <ssi> skunkworks: yeah this is just a continuation of that discussion
[16:02:40] <furrywolf> 700lbs seems awfully light. not planning on anything that light, ever...
[16:02:42] <ssi> furry's flat set on it
[16:02:47] <skunkworks> ah
[16:02:58] <ssi> furrywolf: if you think that sounds light you have zero business trying to build aircraft :D
[16:03:01] <furrywolf> no, I'm not flat set on it. you just suggested it, so now I'm see how it'd work. :P
[16:03:30] <furrywolf> ssi: what can I say, I'm used to building things big and heavy. I've built bumpers that weigh more than an ultralight. :P
[16:03:34] <ssi> it takes power to carry weight; it takes fuel to make power; it takes power to carry fuel
[16:03:38] <ssi> rinse repeat
[16:03:47] <ssi> it's not quite as nefarious as tsoliovsky's rocket equation, but it's close
[16:04:06] <ssi> and it's worse in a heli, because the rotor has to carry the load directly
[16:04:30] <furrywolf> helis need a clutch to start, right? you'd even get that included.
[16:04:30] <JT-Shop> yep everything is a balancing act
[16:04:31] <ssi> I was just looking at the safari... chances are good you're not gonna be able to build anything bigger than a safari
[16:04:36] <ssi> it's 1000lb empty, 1650lb gross
[16:04:46] <ssi> has a 26'4" rotor disc

[16:05:16] <ssi> so use those as starting "sanity" numbers
[16:05:25] <ssi> if you can't get close to that with your napkin design, it's probably not going to work out
[16:05:56] <furrywolf> 180hp isn't hard, but it's probably heavier.
[16:06:16] <ssi> the lyco only weighs 250lb

[16:07:12] <ssi> a safari kit costs $74,400

[16:07:31] <ssi> and that's everything you need except an engine and avionics
[16:07:45] <furrywolf> 180lbs is about what an EJ22T weighs.
[16:07:48] <furrywolf> 280
[16:07:50] <furrywolf> 250
[16:07:51] <furrywolf> bleh
[16:07:55] <ssi> JT-Shop: what do you estimate your bensen would cost to build?
[16:08:39] <furrywolf> ej22 long block is 188lbs, with turbo and stuff probably about 250.
[16:10:34] <furrywolf> someone weighed one at a little under 250lbs. so the engine is actually not heavier. I'm surprised.

[16:55:46] <zeeshan> pcw_home: why is backlash okay on a servo-glass machine?
[16:55:52] <zeeshan> i'm trying to understand the difference
[16:56:07] <pcw_home> backlash is never good
[16:56:35] <zeeshan> lets say youre commanding 1" (reversal) and with backlash you hit .996"
[16:56:53] <zeeshan> wouldnt the position control be like 'there is an error of .004' -- i need to move the stepper another 0.004"
[16:57:13] -!- FreezingAlt has quit [Remote host closed the connection]
[16:57:24] <zeeshan> and continue to do that indefinitely?
[16:57:32] <pcw_home> right, now you want the servo to instantly step .004
[16:57:32] <zeeshan> eveyrtime there is a reversal
[16:57:47] -!- FreezingCold [FreezingCold!~FreezingC@135.0.41.14] has joined #linuxcnc
[16:57:58] <pcw_home> = big quadrant glitches
[16:59:54] <zeeshan> so when it tries to step 0.004" it'll overshoot?
[17:01:04] <pcw_home> well lots of bad things happen (one is inertial load is lower during backlash move)
[17:01:19] <pcw_home> so tuning is different
[17:04:54] <pcw_home> plus backlash simple makes it very difficult to tune
[17:04:55] <pcw_home> I suppose in the stepgen case and with dual (rotary and linear) encoders
[17:04:57] <pcw_home> you could have some very smart controller but the root of the problems is
[17:04:58] <pcw_home> you now have a relatively long response time to external forces of unknown direction
[17:05:46] <jdh> my router with lash digs in when reversing one way
[17:06:21] <pcw_home> yeah this is all without even worrying about tool issues
[17:06:32] <zeeshan> digs in?
[17:07:06] <archivist> climbing, a way to break tools
[17:08:14] <jdh> while it is moving enough to take out the lash, the bit bounces a little then digs in to the materual
[17:08:20] <zeeshan> ah
[17:08:42] <zeeshan> i was wondering if control could compensate for that :P
[17:09:06] <pcw_home> I suspect the tool can be pulled into the work faster than the servo can react and take up the backlash
[17:09:31] <jdh> fix mechamical problems with mechanics, not software
[17:09:54] <zeeshan> jdh: ofcourse :) this was a purely theoretical question
[17:09:59] <zeeshan> on why its not good for the control system
[17:11:52] -!- md-2 has quit [Quit: Leaving...]
[17:12:29] <pcw_home> I the general case imagine how a system with backlash responds with random disturb inputs
[17:12:59] <zeeshan> i can imagine an oscillation
[17:13:38] <zeeshan> tool commands 0.004" movement, tool moves to error free position, the load builds up again causing backlash, and the cycle repeats
[17:14:01] <zeeshan> with a phase shift delay in response
[17:14:09] <pcw_home> Yes, with dual feedback you can eliminate most oscillation but the stiffness at important frequencies is poor
[17:16:15] <pcw_home> now if you have a lot of linear axis mass and small cutting forces backlash is more manageable
[17:16:47] <pcw_home> but thats is not a good machine design

[18:31:33] <zeeshan> that thing
[18:31:45] <ssi> aha
[18:31:51] <zeeshan> was going for 2k
[18:31:54] <zeeshan> slant bed, tool changer etc
[18:31:59] <zeeshan> =/
[18:32:06] <XXCoder1> was it sold?
[18:32:15] <zeeshan> yea it got sold by the time i called
[18:32:20] <XXCoder1> drat
[18:32:28] <zeeshan> prolly a good thing
[18:32:30] <zeeshan> it has fanuc controls :p

[18:35:44] <ssi> I'm fighting with solidworks
[18:35:49] <ssi> it can be a pain in the ass for certain things
[18:35:58] <zeeshan> like what
[18:36:40] <ssi> I'm trying to model a wing truss rib
[18:36:50] <ssi> so I started with a coordinate plot of a NACA 0012
[18:36:55] <ssi> imported it as a curve
[18:37:09] <ssi> then I had to scale that curve to the chord length, cause as imported it's 1" long
[18:37:18] <ssi> now I'm trying to use that as reference geometry for everything else
[18:37:39] <ssi> but annoying stuff like, I need to offset that curve by 1/16" inward to account for leading edge thickness and rib capstrip
[18:37:43] <ssi> and it won't do that reliably
[18:38:02] <ssi> like... if I cut the trailing edge off so that there's room for the new offset path to come to a sharp point, it will do it
[18:38:06] <ssi> but it's behaving oddly and annoyingly
[18:39:49] <ssi> so for instance... I start with the bare sketch of the scaled up curve
[18:40:08] <ssi> I drop a vertical construction line that is coincident with the top and bottom of the curve, and dimension it so that it's 0.15" tall
[18:40:16] <ssi> which positions it some distance from the trailing edge
[18:40:22] <ssi> then I use trim to cut off the trailing edge
[18:40:29] <ssi> then I do an offset entities inward by 0.0625"
[18:40:33] <ssi> and it draws it but says it's unsolvable
[18:40:36] <ssi> and I can't figure out why
[18:40:50] <zeeshan> is it a bunch of points?
[18:40:54] <zeeshan> screenshot? :D
[18:41:10] <ssi> hm
[18:41:11] <ssi> ok
[18:41:12] <ssi> sec
[18:42:27] <ssi> this is gonna be a step by step photojournal
[18:42:31] <ssi> it'll take a few
[18:42:40] <ssi> https://pbs.twimg.com/media/CAPV4pBXEAEEVy7.jpg:large
[18:42:45] <ssi> creating the curve from a coordinate file
[18:42:50] <ssi> https://pbs.twimg.com/media/CAPV8mEWAAI4IU3.jpg:large
[18:42:52] <ssi> the resultant curve
[18:44:09] <ssi> not I can't remember how I did the scale
[18:45:02] <ssi> https://pbs.twimg.com/media/CAPWiB2WMAEERDf.jpg:large
[18:45:05] <ssi> but there's the scaled curve
[18:45:16] <ssi> so now that's the dimension that I want to hold my finished product to
[18:45:41] <ssi> I need a reference line that's 1/16" smaller than that, so I'm going to try to do offset entities from that
[18:45:57] <zeeshan> the curve self interesects
[18:45:58] <zeeshan> in that image
[18:46:00] <ssi> as is, it'll let me go OUT, but not IN
[18:46:11] <zeeshan> on the left
[18:46:12] <ssi> you're seeing two different curves
[18:46:15] <zeeshan> oh
[18:46:17] <zeeshan> hahaha
[18:46:20] <zeeshan> thats a huge scale jump
[18:46:26] <ssi> the big one is a scaled spline from the small one
[18:46:39] <ssi> yes, cause the airfoil coordinates are scaled from 0 to 1 in units of chord
[18:46:45] <ssi> and it imports as 0 to 1 in units of inches
[18:46:50] <ssi> but I need a 36" chord
[18:46:54] <ssi> so I scale the spline by 36
[18:47:07] <ssi> I guess I could scale the coordinate file
[18:47:13] <ssi> but that's not really the issue
[18:47:16] <zeeshan> when you click on the curve
[18:47:22] <zeeshan> is it a bunch of points?
[18:47:29] <ssi> no it's a single spline
[18:47:32] <zeeshan> ok
[18:47:45] <ssi> it's actually a "curve" entity
[18:47:50] -!- swingley has quit [Remote host closed the connection]
[18:48:01] <ssi> Insert > Curve > Curve through XYZ points
[18:48:08] <ssi> give it a text file full of points and it creates the curve
[18:48:26] <ssi> wonder if you could open the part file
[18:48:42] <ssi> do you use dropbox?
[18:48:51] <ssi> I keep all my solidworks crap in dropbox, I could just share you the folder
[18:48:59] <zeeshan> yews
[18:50:47] amnesic is now known as amnesic_away
[18:53:21] <zeeshan> i see the problem
[18:53:31] <zeeshan> zoom in to the very right
[18:53:57] <ssi> yeah...
[18:54:08] <ssi> talking about the "knuckle" in the trailing edge?
[18:54:36] <ssi> maybe I should scale up the raw coordinates and see if it renders better
[18:54:42] <zeeshan> http://i.imgur.com/lDc7tDr.png
[18:54:54] <zeeshan> if you try to offset more than 0.02"
[18:55:04] <ssi> yeah
[18:55:06] <zeeshan> that radius wont hold anymore
[18:55:08] <ssi> that's why I've been cutting off the trailing edge
[18:55:09] <zeeshan> youre limited by that radius
[18:55:18] <ssi> I don't want a radius, I want a sharp trailing edge
[18:55:57] <Jymmm> Is it common for an SSD to draw 1.5A ?
[18:56:31] <renesis> thats seems like a lot but not totally unreasonable, its low voltage
[18:56:35] <ssi> lemme see if I can manually massage the coordinates
[18:56:53] <renesis> jymmm: is that measured or spec?
[18:57:06] <Jymmm> renesis: 5VDC @ 1.6A (rated)
[18:57:17] <renesis> yeah thats like 7W

[18:58:25] <zeeshan> lemme try somethin
[18:58:26] <renesis> jymmm: you already have the ssd?

[18:58:41] <renesis> nice

[18:58:57] <renesis> they prob have some lower power ones, i doubt theyll be cheap as that tho
[18:59:10] <renesis> electronics surplus?
[18:59:15] <zeeshan> i can hack it up
[18:59:17] <zeeshan> if you want
[18:59:18] <zeeshan> and make it work
[18:59:19] <zeeshan> lol
[18:59:30] <Jymmm> renesis: Yeah, I can try and use it in my netbook instead
[19:00:15] <renesis> wonder if the ssd in my eee4g is toast
[19:00:23] <renesis> its soldered onto the board =\
[19:00:35] <Jymmm> http://www.sandisk.com/products/ssd/sata/x110/
[19:00:48] <renesis> one of the rubber dome springs on the keyboard broke off, gotta get new one

[19:01:15] <renesis> Active Power (Typical): 120mW (@ 3.3V)
[19:01:16] <Jymmm> just replace the whole dman kybd =)
[19:01:22] <renesis> yeah thats the plan
[19:01:31] <renesis> but its low priority because its kind of just a neat toy
[19:01:37] <Jymmm> ah
[19:01:51] <renesis> 800x480 display
[19:02:05] <renesis> its literally the first netbook
[19:02:26] <renesis> and the ssd is only 4gb so getting xp on it is drama
[19:02:31] <XXCoder1> aspire one eh
[19:02:32] <Jymmm> I like the netbook cause I have a usb gps wifi, 10" screen and a real uart serial port via EC34 clot
[19:02:36] <renesis> it shipped with linux
[19:02:40] <XXCoder1> ssd yeah I own one, I love it
[19:02:48] <renesis> xxcoder1: asus eee
[19:02:54] <XXCoder1> ah yeah that one
[19:03:08] <Jymmm> Mines a ThinkPad S10 (original, 1st gen)
[19:03:10] <XXCoder1> I decided to go for aspire one, better design
[19:03:17] <renesis> like, within 6 months they released something that was literally scaled up 10%
[19:03:27] <renesis> with a 1024x600 display
[19:03:36] <XXCoder1> well gonna run laters
[19:03:43] <renesis> laters
[19:03:43] <zeeshan> ssi
[19:03:44] <zeeshan> wtf
[19:03:50] <zeeshan> give me upload permission

[19:04:24] <Jymmm> renesis: Lenovo
[19:04:34] <renesis> right but its thinkpad or ideapad?
[19:05:01] <renesis> she got one of their first netbooks but it wasnt thinkpad branded, i forgot the model
[19:05:06] <ssi> zeeshan: what did you do exactly?
[19:05:14] <renesis> but she still uses, she got it prob 5 years ago, maybe longer
[19:05:24] <Jymmm> ah yeah, used to thinkpad, it's IdeaPad =)
[19:05:36] <Jymmm> lenovo S10-1 =)
[19:05:52] <renesis> yeah she dropped it and one of the hinge endcaps popped off
[19:06:10] <zeeshan> ssi use spline tool
[19:06:10] <renesis> years and years ago, besides that i think its been fine
[19:06:19] <zeeshan> start at the intiial point on the left
[19:06:22] <renesis> she uses it in class to push youtube videos to the projector
[19:06:31] <zeeshan> click on the curve a bunch of times especially where it changes radius of curvuture
[19:06:48] <zeeshan> end the spline, then make a line tangent to spline at the right side
[19:07:08] <ssi> k
[19:07:09] <zeeshan> mirror
[19:07:15] <ssi> lemme finish scaling up this naca file and see what it does
[19:07:18] <Jymmm> renesis: faster is nice and all, but I'm hoping it'll save battery life mostly
[19:07:26] <ssi> can't assume mirror, this is a symmetrical foil but most aren't
[19:07:33] <zeeshan> oh
[19:07:49] <zeeshan> thats true you want the top side
[19:07:53] <zeeshan> to be longer than bottom yea?
[19:07:54] <renesis> jymmm: yeah if replacing platter drive it should
[19:08:00] <renesis> its not gonna pull 7W all the time
[19:08:03] <ssi> depends
[19:08:29] <renesis> the link you gave for the product family says 120mW typical
[19:08:37] <Jymmm> renesis: I just con't know how much of a savings
[19:08:48] <renesis> gotta test!
[19:09:27] <Jymmm> yeah, I know. I COULD just read the spec for the hdd in it too =)
[19:09:32] <renesis> would do quick benchmark before swapping
[19:09:58] <zeeshan> lol im looking at one my assignments the prof marked
[19:10:00] <renesis> like, play movie and file copy after reboot, at the end check battery
[19:10:01] <zeeshan> i wrote kW
[19:10:02] <Jymmm> permoane wise?
[19:10:07] <zeeshan> but it looks like kw
[19:10:11] <Jymmm> performance wise?
[19:10:14] <zeeshan> he wrote a big note saying K is kelvin
[19:10:17] <zeeshan> k is kilo

[19:11:07] <renesis> tho you prob have to reinstall system so not great comparison unless you reinstall before swapping, too
[19:11:12] <renesis> which is drama
[19:11:40] <Jymmm> I was going to image the HDD to SSD
[19:11:48] <renesis> but itll give you an idea, itll likely look like better power savings than it actually is
[19:11:59] <renesis> yeah that might work
[19:12:21] <Jymmm> do you need wear leveling stuff instaled?
[19:12:28] <renesis> its built in
[19:12:52] <Jymmm> then why do I always see wear utilit/drivers and shit?
[19:12:58] <renesis> the hardware deals with it, its pretty transparent to the OS, besides checking SMART stuff
[19:13:18] <renesis> because people need to sell software, shrug
[19:13:25] <Jymmm> Yeahs, alwasy seemed dumb to me to have sdd utility/drivers
[19:13:30] <Jymmm> lol
[19:13:42] <renesis> ssd shouldnt need specific drivers
[19:13:50] <renesis> like, manufacturer/model specific
[19:13:54] <Jymmm> sata be sata damnit
[19:14:12] <renesis> right, all the wear leveling is handled in the drive firmware
[19:14:36] <Jymmm> I wonder where they pulled them from, they have 100+ in stock
[19:15:09] <renesis> sounds like initial production fuckup quantity
[19:15:16] <renesis> if they were in an electronics surplus shop
[19:15:58] <Jymmm> Not sure, U'll have to see how they are packaged if at all
[19:16:07] <renesis> not production of the ssd, like someone sourced them for a project and it didnt work
[19:16:54] <renesis> i dont think a computer shop going out of business explains 100+ for one model
[19:16:57] <Jymmm> yeah, I get it. I just hope it's not pulls.
[19:17:12] <renesis> did they look the same?
[19:17:21] <renesis> packaging
[19:17:49] <renesis> if the shit doesnt look all random and handled, would be less worried
[19:17:50] <Jymmm> I dont know, I shop their website first to see whats new, then spend hours in the isle as they dont list everything on the wbesite
[19:17:57] <renesis> oh its a website
[19:18:09] * JT-Shop tries to decide if I want to change bicycle tires or continue welding
[19:18:31] <Jymmm> IT's electronic compontent surplus, but if they have large qty of items, they toss them on the website too.
[19:18:32] <renesis> do you have those tire lever things?
[19:18:43] <renesis> if you dont have those little tire lever things, i would put it off
[19:18:58] <JT-Shop> yea, but you don't need them for a mountain bike tires
[19:19:21] <renesis> you dont, but omg its so much faster, easier, nice to the wheels
[19:19:43] <JT-Shop> you just pull the tire off, no tools needed
[19:20:02] <renesis> mountainbike is that loose?
[19:20:08] <JT-Shop> road bike may be different I don't know
[19:20:16] <JT-Shop> yea, they just fall off
[19:20:18] <renesis> i ride 24" bmx, i assumed 26" would be pretty much same
[19:20:23] <renesis> haha cool
[19:20:29] <JT-Shop> mine is a 29"
[19:20:35] <renesis> yeah i dont ride road bikes, i dont like the larger frames
[19:20:36] <renesis> oh
[19:20:43] <renesis> yeah i bet thats easy
[19:21:09] <JT-Shop> well I do have a 26" too but need to sell it

[20:36:10] <ssi> I think I have it whipped into submission
[20:36:22] <ssi> the problem was that I'm trying to do several lofts along teh same guide curve
[20:36:28] <ssi> and I think it was "consuming" the sketch when I'd do the loft
[20:36:38] <ssi> so I have to make a new sketch and convert the curve over for each loft
[20:36:47] <ssi> this is all because I can't do weldments along a curve :)
[20:37:04] <ssi> so I have short tangent lines at every truss intersection, and weldments there so the trimming works,
[20:37:08] <ssi> then lofting between the tangent lines

[21:22:06] <furrywolf> still, with all your complaining about subaru motors, there seems to be a remarkably large number of them in the air... and now I know of at least one commercial non-kit vehicle with them.

[21:39:52] <ssi> they're actually pretty easy
[21:40:16] <furrywolf> at a quick pulled-from-my-ass guesstimate, there's several tons of force trying to pull them outwards, and they're continually getting a lot of nasty vibration and flexxing.

[23:41:14] <Valen> so the pixels per mm is roughly "a whole bunch"
[23:41:38] <Valen> rootB: do you want to simulate running a machine, or simulate seeing what the shape of the part you are making is
[23:41:43] <Valen> because those are different things
[23:42:22] <Nick001-shop> Can the new Debian 2.6.4 be upgraded to 2.6.7 and how to do it. Also, how do I get the same configurations that were in the Ubuntu disk, Like Stepper-XYZA?
[23:46:48] <SpeedEvil> Valen: Doing it right, you don't focus onto a spot one pixel wide.

[23:47:28] <SpeedEvil> Valen: you can do superresolution - you focus blurrily onto a spot that makes a circle 20 pixels wide, and then you can interpolate to basically ridiculous levels of acccuracy
[23:47:34] <SpeedEvil> What Kepler did.
[23:47:39] <Valen> yeah, but I have this on my mill right now
[23:47:55] <SpeedEvil> Or you just use a ball bearing as a reference.
[23:48:04] <Valen> and I can line up on a hole better than I can measure by any other means ;->
[23:48:09] <Valen> probably about .005mm
