[00:34:08] <CaptHindsight> "low-cost-high-resolution machine that uses a new, sophisticated position feedback system to control its brushed DC motors"
[00:35:04] <CaptHindsight> Its position feedback control system consists of thousands of software code lines written into the RAPPY PUMP DC motor control board.
[00:36:47] <CaptHindsight> http://www.youtube.com/watch?v=iMN8G-ue89A RAPPY's Stability against shock
[00:37:44] <CaptHindsight> he doesn't bump the motors, he just shakes the entire printer
[00:40:04] <CaptHindsight> they should make servos like this :) why waste all that money of encoders and feedback loops
[00:40:12] <CaptHindsight> of/for
[02:10:16] <Deejay__> moin
[02:58:32] <MrSunshine> anyone know a source of "stick fonts" ? (one liners) =)
[03:01:04] <Jymmm> engravers fonts
[03:01:20] <Jymmm> or monospaced
[03:01:58] <MrSunshine> Jymmm, humm ? what do you mean? =)
[03:05:39] <Jymmm> http://www.mrrace.com/CamBam_Fonts/
[03:06:02] <MrSunshine> those were broken :/
[03:06:06] <Jymmm> They're called "Single Stroke Fonts"
[03:06:08] <MrSunshine> or atleast seemed to be ...
[03:09:16] <Jymmm> how so?
[03:12:19] <MrSunshine> in my fontviewer all fonts in the cambam thing just shows up like large globs
[03:13:01] <Jymmm> open in a program
[03:17:42] <MrSunshine> nothing in inkscape
[03:17:55] <MrSunshine> just blobs
[03:28:52] <Tom_itx> http://ncplot.com/stickfont/stickfont.htm
[03:31:15] <MrSunshine> mm gonna try those
[03:33:22] <Jymmm> Tom_itx: Man, some of those are good, some and icky =)
[03:33:31] <MarkusBec> http://www.dafont.com/arcade-ya.font
[03:33:38] <MarkusBec> retro font
[03:34:15] <MrSunshine> oo =)
[03:34:24] <MrSunshine> something i can use for a gift for a friend =)
[03:34:49] <Jymmm> Tom_itx: I just notced those are not TTF
[03:35:09] <MrSunshine> chr .. some kind of vector format ?
[03:35:14] <MrSunshine> looks like it looking at the files
[03:35:17] <MrSunshine> just points and lines
[03:35:44] <MarkusBec> I used it
[03:36:05] <MarkusBec> open it with illustrator str+shift+o
[03:36:12] <MarkusBec> tada vektor :)
[05:36:43] <jthornton> are there better endoscopes or any with better lights? I need to have a look see inside a dark hole on my crawler
[06:20:15] <skunkworks> dad said the matsuura booted - jogged all 3 axis but Y sounds likes something is wrong. (bad tach or something)
[06:20:35] <skunkworks> rough and errored on him.
[06:21:25] <archivist> and son was happy because he then gets to take it to bits to upgrade
[06:25:37] <skunkworks> heh - I think we may trouble shoot it. Plus it lets us see what does what in the control
[07:11:55] * Tom_itx hides skunkworks' wire cutters
[07:13:05] * archivist puts some good cutters on ebay for skunkworks to findl
[07:13:45] <skunkworks> heh
[07:28:33] <skunkworks> it has no tooling... nothing in the spindle..
[07:36:06] <eric_unterhausen> jthornton: better than what?
[07:36:39] <eric_unterhausen> olympus is still making endoscopes, although the Chinese have some nice looking ones
[07:36:56] <jthornton> I don't know anything about them lol
[07:37:16] <jthornton> I did find some have wider view
[07:37:33] <eric_unterhausen> yeah, lots of view options
[07:37:37] <Tom_itx> try the auto store?
[07:37:44] <eric_unterhausen> I find the right angle or 45 degree angle are nice
[07:37:57] <jthornton> I have one coming from amazon
[07:38:11] <Tom_itx> tape a webcam on a stick :)
[07:38:20] <eric_unterhausen> I have a $20, it's just ok
[07:39:12] <jthornton> http://www.amazon.com/Waterproof-Endoscope-Borescope-Inspection-Camera/dp/B00E5M5OG4/ref=sr_1_sc_3?ie=UTF8&qid=1390915341&sr=8-3-spell&keywords=t%26j+world+tm+usb+encoscope
[07:39:46] <skunkworks> -22f here on the drive in...
[07:40:05] <eric_unterhausen> the camera-based ones vary considerably in quality
[09:05:07] <CaptHindsight> http://www.3ders.org/articles/20140128-markforged-mark-one-world-first-carbon-fiber-3d-printer.html not really but you print parts, tooling, and fixtures with a higher strength-to-weight ratio than 6061-T6 Aluminum
[09:28:27] <TekniQue> finally something useful in 3d printing
[09:50:06] <CaptHindsight> there's lots more coming, SLA can print carbon fiber as well only >10X faster
[12:05:47] <IchGuckLive> hi all B)
[12:06:53] <IchGuckLive> today 24 abo on youtube somthing special ?
[12:14:09] <IchGuckLive> CaptHindsight: the 3d pronting is your goal to let the world pay your live
[12:25:25] <ju-emb> somebody here that uses a locked antiphase controller with lcnc?
[12:26:11] <IchGuckLive> of a h-brigh
[12:26:20] <IchGuckLive> bridge
[12:26:47] <ju-emb> Hi IchGuckLive,
[12:26:52] <ju-emb> yes
[12:26:53] <IchGuckLive> hi
[12:27:38] <IchGuckLive> this is what most of us open chees users use
[12:27:53] <ju-emb> what I'm looking for is, can I control a Locked antiphase motordriver with lcnc and use a linear encoder as feedback
[12:27:58] <IchGuckLive> you want to go pwm mode
[12:29:14] <ju-emb> yes PWM , center aligned < 50% left > 50% right or so
[12:29:22] <IchGuckLive> ju-emb: http://linuxcnc.org/docs/html/drivers/hostmot2.html#_parameters_4
[12:30:10] <ju-emb> I think that helps, thanks to Karlsruhe
[12:30:20] <IchGuckLive> as you go with mesa stuff this is ok and will work
[12:30:36] <IchGuckLive> ju ;-) im in kaiserslautern
[12:30:53] <ju-emb> at least the PCI anything IO is from Mesa
[12:31:23] <ju-emb> Sorry, that was the right offense
[12:31:53] <IchGuckLive> selfmade driver od opendrivers
[12:32:52] <IchGuckLive> 7i33
[12:32:53] <ju-emb> I've to test performance, most I tend to do the drivers myself
[12:34:00] <ju-emb> the Mesa Stuff is really great, I love it, but I hate that cabeling
[12:34:23] <IchGuckLive> cableling is the best of itr
[12:34:34] <IchGuckLive> as you then know your mashine in detail
[12:34:47] <IchGuckLive> plug and play is a hard to anderstand thing
[12:35:52] <ju-emb> We have really rough environment here so every cm of cable is a potential error cause
[12:36:12] <pcw_home> If you use the three phase PWM (even just one output) you get default locked antiphase
[12:36:46] <ju-emb> plug and play is not the problem, is the cable itself and how to run them inside your machine
[12:37:12] <IchGuckLive> ju-emb: i know asways a hard time
[12:37:16] <pcw_home> (otherwise you need to use the scale comp or something similar to get the 50 % offset)
[12:39:22] <ju-emb> pcw_home: give me some more hints please
[12:44:22] <pcw_home> default pwm will be PWM and DIR (but three phase is normally 50%)
[12:44:34] <ju-emb> Parameters for PWMGen output-type : 4 Direction on Out0 and PWM on Out1, for locked antiphase)
[12:44:34] <pcw_home> bbl
[12:44:36] <ju-emb> what do I need direction on locked antiphase for?
[12:56:27] <IchGuckLive> hi uw all running now
[12:56:44] <uw> hello IchGuckLive
[12:56:59] <uw> all running?
[12:57:52] <IchGuckLive> your servo setup
[13:02:13] <uw> ohh no not yet :/
[13:02:46] <IchGuckLive> still some homing problems
[13:03:36] <uw> well, after more research i think I will do away with the mill i'm was going to convert
[13:04:02] <uw> and get a better one instead, as the one I have is currently limited
[13:04:15] <IchGuckLive> as you think
[13:04:18] <uw> (circle post mill/drill)
[13:04:49] <uw> have you made anything today?
[13:07:47] <IchGuckLive> no
[13:14:35] <skunkworks> http://imagebin.org/289583
[13:15:17] <uw> same here. doing other things last few days and not much time/need for cnc :)
[13:15:34] <IchGuckLive> skunkworks as i said yesterday magic hands you got
[13:25:19] <toast-work> skunkworks: do you have the programming manual for the yasnac
[13:25:51] <skunkworks> toast-work, I don't know - Dad thinks he has one for an older version.
[13:26:10] <skunkworks> I don't know what version of control that is - Do you?
[13:28:28] <toast-work> no idea, i'd search the PM archives and post there
[13:28:31] <toast-work> they'll be able to help for sure
[13:31:13] <IchGuckLive> im off BYE
[14:01:36] <PetefromTn> Jeez man I am about to give up on this Cam stuff LOL..
[14:02:43] * GuShH_ pats PetefromTn
[14:02:57] <PetefromTn> LOL thanks man.. hehe
[14:03:37] <PetefromTn> Been trying to work with some 3d stuff in CamBam and thought I had it there for a minute but the part after I ran it in simulation has a problem I cannot figure out.
[14:04:25] <PetefromTn> The program does not have a native simulation that makes things complicated too. I have been playing with CNCsimulatorPro and CUtviewer here.
[14:28:21] <onyedi_linux> skunkworks: I had an error during the new Trajectory Planner install can you help me on that ?
[14:28:58] <skunkworks> what is the error?
[14:29:18] <skunkworks> use pastebin.ca
[14:30:20] <onyedi_linux> http://pastebin.ca/2596891
[14:30:32] <onyedi_linux> it failed on make command
[14:31:29] <skunkworks> ah - sudo apt-get install cscope
[14:31:53] <skunkworks> make sure you add the needed lines to the ini file also
[14:32:14] <skunkworks> (from the forum thread) [traj] section
[14:35:37] <onyedi_linux> how do i run linuxcnc without a machine connected, for simulation ?
[14:37:47] <skunkworks> pick one of the sim configurations..
[14:41:52] <onyedi_linux> is it possible to use my machines settings as a sim machine?
[14:50:42] <onyedi_linux> or is it possible to change one of the sim machines velocity and acceleration settings?
[14:54:36] <onyedi_linux> i will just edit the ini, hope it works that way
[15:04:03] <onyedi_linux> yeah that did the trick
[15:05:29] <onyedi_linux> skunkworks: the new TP shows obvious improvements on velocity, i will try it live tomorrow. Thank you.
[15:05:50] <skunkworks> great - let us know
[15:08:44] <Tom_itx> Pete left too quick
[15:10:40] <PCW> his CAM program wrestled him to the ground...
[15:10:59] <Tom_itx> seems it beat the crap outta him
[15:12:09] <Tom_itx> what he's tryin to do isn't that hard
[15:25:01] * Tom_L snickers a bit
[15:25:04] <Tom_L> http://www.electronicproducts.com/Software/Development_Tools_and_Software/Throwback_Tech_15_formerly_awesome_electronics.aspx
[15:29:05] <Loetmichel> hmmm
[15:29:31] <Loetmichel> how do i do a loop in gcode with incrementing (actually decrementing z?
[15:29:45] <Loetmichel> any link to a sample code?
[15:32:56] <`Nerobro> Loetmichel, cut and paste..
[15:35:23] <micges> Loetmichel: http://www.linuxcnc.org/docs/html/gcode/o-code.html#sec:looping
[15:35:46] <Loetmichel> micges: thx
[15:37:54] <CaptHindsight> http://www.3ders.org/articles/20140128-let-the-revolution-begin-key-3d-printing-patent-expires-today.html
[15:38:49] <jmasseo> http://www.ebay.com/itm/CNC-3020-ROUTER-ENGRAVER-ENGRAVING-DRILLING-MILLING-MACHINE-3-AXIS-DESKTOP-/291049745815
[15:38:52] <jmasseo> $189?
[15:39:06] <jmasseo> oh
[15:39:08] <jmasseo> $555 shipping.
[15:39:09] <jmasseo> nevermind
[15:39:23] <jdh> they go for like $570 shipped
[15:39:35] <jmasseo> anybody tried one?
[15:39:56] <jdh> someone has a 6040
[15:40:02] <jdh> 3020 is pretty tiny
[15:40:06] <jmasseo> yeah
[15:40:08] <CaptHindsight> Are there any lower cost galvo based laser cutters on market?
[15:40:58] <CaptHindsight> what size work area are you looking for?
[15:41:10] <CaptHindsight> jmasseo: ^^
[15:41:10] <jmasseo> i'm mostly speculating.
[15:41:20] <jmasseo> i'd like to have something at home to play with
[15:41:23] <jmasseo> more for an interest in CNC
[15:41:26] <jmasseo> than for any particular project
[15:41:35] <jdh> should be fine then.
[15:41:43] <jmasseo> i have access to various machines, i just don't have anything of my own to fudge with
[15:42:06] <CaptHindsight> Other patents set to expire this year include 3 patents from 3D Systems (all SLA methods) and 6 from Stratasys which involve FDM, support removal, and optimization.
[15:42:11] <jmasseo> 5 axis 3040?
[15:42:14] <jmasseo> that's pretty crazy
[15:42:30] <jmasseo> might be super useful for jewelry stuff.
[15:43:17] <CaptHindsight> the res is pretty poor on those with the no name 4th and 5th axis
[15:43:23] <jmasseo> i believe that
[15:43:28] <CaptHindsight> good enough for engraving
[15:43:57] <Jymmm> CaptHindsight: not on jewlery
[15:45:27] <jmasseo> i'd really like the 4th axis taig.
[15:45:28] <CaptHindsight> Jymmm: have you seen a galvo laser cutter in the same price range as the small desktops?
[15:45:55] <Jymmm> CaptHindsight: desktop what? mech engravers or lasers?
[15:46:22] <CaptHindsight> laser engravers
[15:46:32] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/laser-engraving/co2-laser-machine-rotary-device
[15:48:23] <Jymmm> CaptHindsight: CO2 can't do metal unless high power, need a YaG
[15:48:56] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/laser-engraving/40w-co2-laser-machine-software-training
[15:49:25] <Jymmm> rotary attachement is for things like wine flutes or wooden pens
[15:49:37] <Jymmm> or champagne bottles
[15:49:55] <CaptHindsight> Jymmm: there are 2 conversations going on here
[15:50:08] <Jymmm> Well, I'm out on both =)
[15:50:21] <CaptHindsight> one is: are there low cost galvo laser cutter engravers
[15:50:28] <MrSunshine> gah fail on the grind of the taper
[15:50:41] <MrSunshine> the ER collet engages and clamps the backside of stuff first ...
[15:50:59] <CaptHindsight> #2 is the discussion on the small cnc router, these two got conflated
[15:50:59] <MrSunshine> and its quite a bit off, as i turn the nut and clamp down the nut i can go quite a bit before it clamps the end :/
[15:51:29] <CaptHindsight> Yag me with a laser
[16:27:30] <MrSunshine> any tips on setting up and angle in the lathe using a sine bar? =)
[16:27:44] <MrSunshine> that is, how to holw the darn thing straight in every way so ic an indicate the bastard :P
[16:29:27] <MrSunshine> need a true and straight reference surface i guess ...
[16:35:06] <syyl-> like this?
[16:35:06] <syyl-> https://dl.dropboxusercontent.com/u/24396704/IMG_1912.JPG
[16:35:27] <syyl-> i scraped the side of the slide true to its ways
[16:35:47] <Deejay> gn8
[16:36:23] <MrSunshine> looks nice but i cant scrape the sides true with the ways on this lathe, dont know if its realy that critical and i might be able to use just the side of the compound as reference but =)
[16:43:26] <CaptHindsight> I could use a small nema17 stepper controlled 3 axis stage. I only need a few inches of travel XY
[16:44:03] <CaptHindsight> where can you buy one now?
[16:51:35] <JT-Shop> another cold day on the bridge
[16:57:00] <uw> how does that scraping work
[16:57:23] <uw> i've read about that a little but sounds like you need expensive stuff to make it worth a damn
[16:57:40] <uw> like large 6" thick granite tables
[16:59:24] <Tom_itx> CaptHindsight, sherline has em
[16:59:31] <Tom_itx> nema23
[17:02:04] <Loetmichel> uw: the only expensive part at scraping is the "ruler" you'll need to check your work
[17:02:09] <Loetmichel> the rest is cheap
[17:02:50] <Loetmichel> a scraper with a Tungsten carbide tip, a biot of blue "paint", tons of patience and muscle ;-)
[17:03:07] <uw> Loetmichel, what kind of gains can you expect from scraping?
[17:03:42] <Loetmichel> VERY flat surfacese with a great lok and good oil film "grip"
[17:04:03] <Loetmichel> the typical mill and lathe ways are scraped
[17:04:34] <Loetmichel> if you see the charactaristic "crisscross" pattern you know its scraped
[17:05:21] <uw> my big mill is scraped from factory
[17:05:35] <uw> sherline no, but the other is
[17:05:47] <Loetmichel> yeah, you can do that yourself if it ever gets a "run in"
[17:05:49] <uw> do you have to "rescrape" a mill or lathe ever?
[17:06:31] <Loetmichel> ways will suffer from wear like any gliding surface
[17:06:48] <Loetmichel> so: after a long time it will need to be rescraped, yes
[17:07:26] <Loetmichel> the pint is: as long as you have a precise ruler you can make any surface flat and level
[17:07:42] <Loetmichel> to less than half a thou
[17:07:46] <Loetmichel> if you want to
[17:08:59] <Loetmichel> even to less than a µm if you have the right straight edge and enough patience ;-)
[17:09:29] <uw> just by eye?
[17:09:45] <Loetmichel> you can even make your own rulers from billets.
[17:09:47] <uw> sounds like magic almost Loetmichel ;0
[17:09:52] <Loetmichel> (needs three of them, though
[17:09:56] <Loetmichel> )
[17:10:11] <Loetmichel> just by eye with the help of a bit of paint
[17:10:16] <Loetmichel> and physics ;-)
[17:11:36] <Loetmichel> http://www.youtube.com/watch?v=LkdkouWiDFs
[17:17:35] <Einar_> In the video he make the scraper blade straight. It should be slightly curved.
[17:20:32] <Loetmichel> Einar_: i thought so,too
[17:20:47] <Loetmichel> but a slight curvature might be enough
[17:21:42] <Einar_> Not really. You "adjust" the curvature by laying the scraper almost flat to the surface, and raise it to be more agressive.
[17:22:26] <Loetmichel> Einar_: i meant: maybe he had enough curvature for his wy of working
[17:23:09] <Loetmichel> and as he said: "its a work in progress, he is still learning"
[17:23:32] <Loetmichel> if you want to learn from the pro, look for videos from muellernick
[17:23:47] <uw> this appears to be a very "craftsman" type of work...
[17:23:53] <Loetmichel> he is from around here ( e few 100 km) and is REALLY good
[17:24:19] <Loetmichel> uw: like i said: LOTS of patience needed
[17:24:26] <Loetmichel> but you CAN do it yourself
[17:24:47] <Einar_> Yes, I just watch this, and it looks much more correct: http://www.youtube.com/watch?v=D1eOQa1gYiU
[17:25:12] <Loetmichel> and there even is a "trick" to make your own straigt edges/flat surfaces from nothing more than three eaqually sized plates
[17:29:00] <CaptHindsight> http://www.ebay.com/itm/181178381752 "Linear Motion Slide Actuator Nema 17 Stepper Motor" looks like a used inkjet printer carriage lol
[17:31:27] <JT-Shop> http://www.youtube.com/user/MuellerNick
[17:32:39] * JT-Shop tries to get motivated to work on the hydraulic tank
[17:32:58] * Tom_itx gives JT-Shop some JBweld
[17:33:12] <uw> he is using crazy tool with a dial
[17:33:55] <Loetmichel> uw: thats just to get the inital readings whre the dovetail is off
[17:34:03] <Loetmichel> it gest interesting shortly after ;-)
[17:37:18] <JT-Shop> http://www.youtube.com/watch?v=OG3PnQ3tgzY
[17:38:23] <uw> this is very craftsman work
[17:38:38] <Einar_> Me like! I'm also an instrument hoarder. :-)
[17:38:39] <uw> is there a way to do this via CNC :)
[17:39:09] <Loetmichel> uw: not in this precision
[17:41:46] <uw> i dont think i will ever do this
[17:42:02] <uw> too time consuming and needing of special tools
[17:42:06] <JT-Shop> http://home.comcast.net/~jaswensen/machines/straight_edge/straight_edge.html
[17:42:12] <uw> (like scraper and grannite)
[17:51:36] <Loetmichel> JT-Shop: that was the link i searched
[17:51:52] <Loetmichel> to make a straigth edge/surface plate from scratch
[17:52:11] <Loetmichel> ... actually: 3 straight edges/surface plates ;-)
[17:53:41] <Loetmichel> so, going to bed now
[17:54:51] <Nick001> <JT-Shop> what power supply do you use for your anodizing
[17:59:33] <JT-Shop> Astron VS-70M
[18:00:23] <Nick001> Thanks - do you remember the supplier?
[18:01:55] <Nick001> Did you get your system to work with coloring and final seal?
[18:02:07] <JT-Shop> no, but I'll look
[18:02:29] <JT-Shop> DX Engineering
[18:03:12] <JT-Shop> yes, I'm moving things around a bit now for better work flow
[18:06:15] <Nick001> Thanks for the info. Is there much of a smell in the shop from this?
[18:06:51] <JT-Shop> no, I don't use air to circulate the acid bath
[18:08:13] <JT-Shop> moonlite telescope has a good book on anodizing

[18:12:31] <Nick001> Plastic propeller?
[18:12:49] * JT-Shop heads inside
[19:10:05] <CaptHindsight> http://imagebin.org/289623 I need to motorize this. Has anyone seen off-the-shelf units that are motorized? 1-2cm of travel
[19:10:36] <CaptHindsight> don't need piezo accuracy
[19:14:13] <CaptHindsight> I think those are 80tpi screws
[19:26:07] <uw> 80tpi wat
[19:26:20] <eric_unterhausen> is that a double screw?
[19:26:32] <eric_unterhausen> or what is the coarse thread in the back?
[19:26:34] <uw> looks like spring
[19:26:43] <eric_unterhausen> duh
[19:26:47] <uw> for back lash lol
[19:26:53] <eric_unterhausen> ic now
[19:27:25] <eric_unterhausen> isn't newport pretty much it for motorized mini-slides?
[19:27:45] <uw> i wish there was pencil or something next to it for scale
[19:28:02] <eric_unterhausen> 1/4-20 hole in slide
[19:28:16] <uw> oh gotcha
[19:28:20] <uw> that is mini
[19:28:24] <eric_unterhausen> I just made that up
[19:28:48] <uw> :|
[19:29:11] <eric_unterhausen> I give it even odds
[19:30:09] <uw> i'd say odds even
[19:30:31] <eric_unterhausen> 81 tpi would be weird
[19:32:38] <Valen> you can get micro steppers with linear actuators off the ebays for a $ or two
[19:33:40] <CaptHindsight> each positioner is ~0.5" x 1.75"
[19:35:25] <CaptHindsight> http://www.ebay.com/itm/370989283234 bingo, thanks Valen
[19:35:58] <uw> wonder if they make steppers the size of cellphone vibra motors
[19:36:24] <CaptHindsight> I tried linear stage, xy stage, etc etc on ebay
[19:36:34] <CaptHindsight> sometimes it takes the magic words
[19:37:01] <Valen> uw i have some 6mm dia steppers
[19:37:37] <Valen> CaptHindsight: http://www.ebay.com/itm/10pcs-2-phase-4-wire-stepper-motor-micro-stepping-motor-6mm-Canon-/181293933573?pt=LH_DefaultDomain_0&hash=item2a35f5e405

[19:37:49] <CaptHindsight> heh, same ones
[19:38:05] <CaptHindsight> need them by Friday
[19:38:42] <CaptHindsight> China is closed until Feb 4th or so for cleaning and New Years/Spring Festival

[19:41:31] <CaptHindsight> oh, gear reduction stepper
[19:44:03] <CaptHindsight> it looks like many cars use miniature stepper motors in the dash for the speedo

[20:27:37] <julby0> *105
[20:27:47] <CaptHindsight> maybe 90 left?
[20:28:05] <Tom_itx> some of the ole pharts are sleepin in their chairs
[20:28:19] <eric_unterhausen> some people are always leaving
[20:28:28] <eric_unterhausen> is there a way to turn off those messages?
[20:28:36] <Tom_itx> what messages?
[20:28:39] <Tom_itx> join part?
[20:28:45] <Tom_itx> depends on your client
[20:28:48] <eric_unterhausen> left/join
[20:29:03] <Tom_itx> i remove them from my logs
[20:29:05] <eric_unterhausen> I was looking for that, didn't see it
[20:29:10] <julby0> I have 10-12 years of computer programming experience (lots of languages), I'm 24, and I'm thinking about going to vocational school to learn CNC and I'm wondering if that sounds like a bad idea to people? will i just be starting from scratch or is there overlap
[20:29:13] <Tom_itx> what client?
[20:29:22] <eric_unterhausen> pigin
[20:29:28] <Tom_itx> never used it, sry
[20:29:32] <eric_unterhausen> aka pidgin
[20:30:02] <Tom_itx> julby0 learn a cad cam package at a vo tech
[20:30:12] <CaptHindsight> julby0: by cnc you mean programming g-code or running cnc machines?
[20:30:19] <julby0> the school covers both
[20:30:26] <Tom_itx> if that's what you like
[20:30:47] <Tom_itx> programmers get paid more than button pushing monkeys
[20:30:53] <eric_unterhausen> I visited a votech that was selling a HAAS. That place looked really interesting
[20:31:10] <eric_unterhausen> there was a mastercam class going on, lots of students out on the floor machining
[20:31:22] <Tom_itx> yep they teach it here
[20:31:28] <Tom_itx> also catia
[20:31:31] <CaptHindsight> button pushing monkey programmer
[20:31:51] <zeeshan> Tom_itx:
[20:32:07] <zeeshan> at this one company i was working at, the button pushers got 22$/hr
[20:32:08] <zeeshan> lol
[20:32:16] <zeeshan> they did do measurements every 10th parth though
[20:32:29] <zeeshan> and were loading/unloading parts 3 machines at a time
[20:32:33] <Tom_itx> i was getting 35 for programming
[20:32:37] <CaptHindsight> some of us were just thrown into a machine shop and had to learn machine or sink
[20:32:40] <Tom_itx> way back when...
[20:32:40] <zeeshan> yea programmers get awayy more
[20:32:47] <eric_unterhausen> you can get engineering jobs that require cnc programming
[20:32:59] <zeeshan> eric_unterhausen: those jobs suck
[20:33:00] <zeeshan> :)
[20:33:09] <Tom_itx> CaptHindsight yep that's how alot of it is done
[20:33:15] <Tom_itx> sink or swim
[20:33:17] <eric_unterhausen> I met a guy that did it and seemed pretty happy about it
[20:33:33] <Tom_itx> i had a friend i got hired on at my bud's shop
[20:33:51] <Tom_itx> started sweeping the floors and left running quite a few of the machines
[20:33:54] <zeeshan> i'd kill myself
[20:34:00] <zeeshan> if my job was cnc programming
[20:34:03] <zeeshan> as a mech eng
[20:34:03] <julby0> why
[20:34:13] <zeeshan> cause i did that shit as a technologist for 2 years
[20:34:17] <zeeshan> and it got boring really fast
[20:34:18] <CaptHindsight> it also depends on what industry your machine shop is in
[20:34:25] <Tom_itx> yeah
[20:34:31] <zeeshan> i was programming robots (pick and place) and cnc machines
[20:34:36] <zeeshan> aerospace
[20:34:41] <Tom_itx> where?
[20:34:57] <CaptHindsight> are you on government/military contracts or some fading industry
[20:35:07] <Tom_itx> aerospace is becoming more locked in on price
[20:35:41] <zeeshan> you prolly havent heard of it
[20:35:43] <zeeshan> goodrich
[20:36:00] <Tom_itx> they make tires
[20:36:05] <zeeshan> wrong company
[20:36:06] <zeeshan> sir
[20:36:09] <Tom_itx> :)
[20:36:10] <zeeshan> haha
[20:36:32] <Tom_itx> i didn't say they had a blimp
[20:36:45] <zeeshan> yea i went back to school and doing my masters
[20:36:49] <zeeshan> so i can do a mix of things
[20:36:58] <zeeshan> for me personally icant handle doing the same thing
[20:37:02] <zeeshan> need something new
[20:37:21] <Tom_itx> you'd get bored quick running cnc
[20:37:27] <CaptHindsight> zeeshan: what were the pick-n-place files like? just X xxxx.xxx , Y xxxx.xxx or similar?
[20:37:28] <zeeshan> i know plenty of people that love programming through mastercam
[20:37:42] <Tom_itx> i looked at mastercam when i bought mine
[20:37:48] <julby0> is cnc anything like regular programming
[20:37:49] <Tom_itx> i didn't like it quite as much
[20:38:23] <zeeshan> CaptHindsight: theyre all the same
[20:38:26] <CaptHindsight> julby0: http://linuxcnc.org/docs/html/gcode.html
[20:38:29] <Tom_itx> the problem with small shops is most of the time the parts they get are stuff that is HOT and has to get done quick
[20:38:36] <zeeshan> you basically set joint mode , cartesian mode, set the speed
[20:38:37] <zeeshan> mvoe the arm
[20:38:44] <Tom_itx> unless you're a lucky one that has a contract for parts
[20:38:54] <zeeshan> mitsubishi has a different set of codes, fanuc has a different set of codes and abb has a different set of codes
[20:39:10] <zeeshan> by codes i mean commands
[20:39:23] <zeeshan> i wonder if i have the video of my making the robot dance
[20:39:33] <zeeshan> during plant shutdown
[20:39:33] <zeeshan> :)
[20:39:53] <zeeshan> towards the end it swoops down and turn its end effector and gave a middle finger pretty much
[20:40:01] <zeeshan> :)
[20:40:07] <CaptHindsight> zeeshan: was this you? http://www.youtube.com/watch?v=wOCmoYU6h1Q
[20:40:20] <zeeshan> CaptHindsight: no :(
[20:40:22] <zeeshan> i'd prolly puke
[20:40:29] <zeeshan> you wanna know what the abb robot was doing?|
[20:40:33] <zeeshan> its entire job?
[20:40:52] <zeeshan> it would take a part that came out of a cnc machine drilled in a bunch of places
[20:41:04] <zeeshan> and push it against a spinning bristle brush to deburr
[20:41:10] <zeeshan> and then load it to the other machine
[20:41:13] <zeeshan> poor robot.
[20:41:16] <CaptHindsight> for how long?
[20:41:24] <zeeshan> 30 second brush time
[20:41:40] <zeeshan> cycle time for the whole operation was like 45 seconds
[20:41:56] <CaptHindsight> did the robot ever complain, get sick or ask for a raise?
[20:42:05] <zeeshan> yes
[20:42:16] <zeeshan> it'd start dropping parts at the wrong place
[20:42:17] <CaptHindsight> serves managment right!!
[20:42:18] <zeeshan> haha
[20:43:39] <zeeshan> i cant find the damn video
[20:43:40] <zeeshan> but i did find this
[20:43:59] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/3FC67967-6C17-494D-A3A7-FD9E7292EE55-2301-0000022C0117D1D9_zpsb6c30cb5.jpg
[20:44:20] <zeeshan> guess size
[20:45:55] <zeeshan> 2" diameter cables
[20:45:55] <zeeshan> ;D
[20:46:08] <CaptHindsight> big buss bar to
[20:46:38] <zeeshan> these guys used copper
[20:46:40] <zeeshan> like it was free
[20:47:03] <CaptHindsight> bending those conductors in a box is really fun
[20:47:17] <zeeshan> luckily those are aluminum
[20:47:21] <zeeshan> copper is retarded
[20:47:32] <zeeshan> they use a hydraulic bender
[20:48:13] <CaptHindsight> we also used a tool that was similar to a "hickey" bender
[20:49:01] <zeeshan> i found a set of pics from another job
[20:49:11] <CaptHindsight> that was in another life
[20:49:15] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/work_abba_systems/PIC-0113.jpg
[20:49:30] <zeeshan> this job required "Reverse engineering", designing
[20:49:31] <zeeshan> and programming
[20:49:34] <zeeshan> i think the coolest part was
[20:49:36] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/work_abba_systems/mold.png
[20:49:48] <zeeshan> the fact that those molds were all made out of stainless steel
[20:49:58] <zeeshan> and some of the components that went inside it needed to be "hard turned"
[20:50:11] <zeeshan> 62HRc hardness
[20:50:27] <zeeshan> the finishing was done on grinders that were stupid precise
[20:50:47] <zeeshan> they monitored the part diameter real time using a marposs made gauge
[20:50:53] <CaptHindsight> http://s130.photobucket.com/user/turbozee84/media/work_abba_systems/PIC-0116.jpg.html Faro arm?
[20:50:57] <zeeshan> and at the same time monitored the tool post vibration due to the machine
[20:51:15] <zeeshan> all while thats going on it'd closed loop it's way to its target dimension
[20:51:17] <zeeshan> amazing!
[20:51:21] <zeeshan> yes
[20:51:24] <zeeshan> faro arm
[20:51:48] <zeeshan> a lot of aerospace companies don't allow pics
[20:51:52] <zeeshan> :(
[20:52:30] <CaptHindsight> I just wear camera glasses now :)
[20:52:31] <Tom_itx> one here we visited was making 117 parts, they escorted us thru the shop
[20:52:49] <eric_unterhausen> I was at faro recently, business seems to be doing well
[20:53:21] <CaptHindsight> sir, why are wearing helmet with a spot light?
[20:53:27] <zeeshan> haha
[20:53:40] <CaptHindsight> safety first
[20:53:40] <zeeshan> well that process i described to you earlier
[20:53:45] <zeeshan> its all propietry shit
[20:53:54] <zeeshan> they think others dont do it
[20:53:57] <zeeshan> but others are
[20:54:06] <zeeshan> so i don't know why all the secrecy
[20:54:13] <zeeshan> not anyone can start a 100million dollar operation overnight
[20:54:29] <CaptHindsight> http://www.popularmechanics.com/technology/gadgets/news/new-3d-printer-by-markforged-can-print-with-carbon-fiber-16428727?click=pm_latest
[20:54:48] <julby0> how much can a cnc programmer make?
[20:54:53] <julby0> in U.S.
[20:55:02] <CaptHindsight> FDM with carbon fiber in the filament
[20:55:32] <zeeshan> julby0: depends
[20:55:38] <zeeshan> if they're doing complex 5 axis programming
[20:55:39] <CaptHindsight> someone ^^ said used to make $35/hr
[20:55:45] <zeeshan> i've seen them make 35-40$ hr ez
[20:56:16] <julby0> that seems like the same as what a software engineer would make
[20:56:44] <CaptHindsight> depends on the area and projects
[20:56:44] <zeeshan> julby0: programmers make more initially
[20:56:59] <zeeshan> engineers make less initially and then with experience they start making more ;p
[20:58:02] <CaptHindsight> you don't get much hands on in engineering school, lots of reckinin, arts and lecture :)
[20:58:22] <zeeshan> i agree
[20:58:32] <zeeshan> thats why i started off at a technical college first
[20:58:49] <zeeshan> did 3 years there, got amazing experience and did co-ops and worked after
[20:58:53] <CaptHindsight> it all depends, some people get a BS is ME and end up making tons, some get PhD's and wash dishes
[20:59:05] <zeeshan> now im almsot done my undergrad and starting masters this summer
[20:59:15] <zeeshan> and you'll be suprised how many "engineers" can't hold a vernier caliper right
[20:59:23] <zeeshan> a venier caliper is not a 2 hand instrument!
[20:59:33] <zeeshan> nor is it a screw driver..
[20:59:47] <julby0> there's a wrong way to hold a caliper?
[21:00:00] <CaptHindsight> my way and the other way
[21:00:01] <zeeshan> julby0: theres a way to hold it that will get you laughed at by any machinst
[21:00:12] <julby0> why
[21:00:18] <zeeshan> you hold the caliper with one hand
[21:00:27] <zeeshan> use the thumbwheel to close the jaws
[21:00:34] <zeeshan> not close the jaws with both hands
[21:00:38] <zeeshan> it throws off your readings
[21:00:43] <julby0> i didn't know that
[21:00:58] <julby0> i wondered what the point of the thumbscrew was
[21:01:20] <zeeshan> http://www.listoftools.com/images/using_vernier_calipers_for_an_outside_diameter.png
[21:01:24] <zeeshan> hold part with one hand
[21:01:27] <zeeshan> hold vanier with other
[21:01:30] <zeeshan> vernier
[21:02:32] <eric_unterhausen> machinist will laugh at you anyway BTDT
[21:02:48] <julby0> the moral is that machinists have an odd sense of humor
[21:03:10] <zeeshan> i have a question for you guys
[21:03:17] <zeeshan> i love this question.
[21:03:29] <eric_unterhausen> it's when a man and a woman love each other very much
[21:03:40] <zeeshan> you have a manual lathe. you need to make 3x3x3 cube
[21:03:43] <zeeshan> how do you do it?
[21:03:43] <zeeshan> :D
[21:03:48] <Tom_itx> easy
[21:03:51] <zeeshan> haha
[21:03:56] <zeeshan> Tom_itx: don't ruin it!
[21:04:11] <eric_unterhausen> ya, I can do that, and I actually have
[21:04:18] <zeeshan> that was one of my final exam questions in college lol
[21:04:20] <Tom_itx> you can make one of those cube in a cube in a cube like that too
[21:04:39] <zeeshan> tell me!
[21:04:42] <eric_unterhausen> you see cubes with facing marks on them in shops without a mill
[21:05:02] <CaptHindsight> milling on a lathe
[21:05:06] <zeeshan> i think i forgot to mention a key thing
[21:05:13] <zeeshan> you're starting off with round stock of any size you want
[21:05:14] <eric_unterhausen> no 4 jaw chuck?
[21:05:23] <zeeshan> you can use a 4 jaw
[21:05:33] <CaptHindsight> no chuck just for extra difficulty
[21:05:37] <zeeshan> hjaha
[21:05:44] <eric_unterhausen> face, flip, face, etc
[21:05:48] <zeeshan> exactly!
[21:05:55] <zeeshan> guess how many people got that question right?
[21:06:01] <eric_unterhausen> 1?
[21:06:04] <Valen> i was thinking there was some trick answer?
[21:06:05] <zeeshan> 4/120
[21:06:31] <eric_unterhausen> my boss had to make a cube with a chisel
[21:06:39] <Tom_itx> you'll have to do better than that...
[21:06:41] <zeeshan> haha that's intense
[21:06:53] <Valen> I'd bolt the bigass fly cutter into the chuck, bolt the block in in place of the tool post and just wind it past
[21:06:58] <zeeshan> Tom_itx: cmon it's a trick question if many of the class couldnt get it
[21:07:01] <eric_unterhausen> he still likes the idea, I have never figured out why
[21:07:01] <zeeshan> you guys are experienced :)
[21:07:25] <zeeshan> valen lol
[21:07:27] <eric_unterhausen> no, had no mill
[21:07:46] <Valen> eric_unterhausen: that doesn't involve a mill
[21:07:55] <Valen> put a milling bit into the lathe chuck
[21:08:09] <Valen> one of my friends was doing apprenticeship at qantas, first job was to make a 25mm (1 inch) cube
[21:08:15] <eric_unterhausen> I was just addressing the part that we were experienced
[21:08:27] <jdh> Valen: with a file?
[21:08:28] <Valen> thing is if there was any defect it would be rejected
[21:08:35] <zeeshan> haha with a file
[21:08:37] <zeeshan> i'd kill myself
[21:08:40] <Valen> jdh: they were told they could use any tool
[21:08:53] <Valen> the correct answer was use a file ;->
[21:09:05] <Valen> anything else left marks in the job
[21:09:07] <CaptHindsight> and he had to start with a 10' length of rusty plumbing pipe
[21:09:27] <theorbtwo> Valen: Already fail. 1 inch is 25.4 mm.
[21:09:34] <jdh> real men would make the file first
[21:09:54] <CaptHindsight> when I was a kid I wish we had files...
[21:10:06] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/v_plate_zpsead90cf7.jpg
[21:10:09] <zeeshan> im proud of this attachement i made
[21:10:10] <jdh> yeah, we just had shark rocks
[21:10:15] <CaptHindsight> just rough and smooth rocks
[21:10:17] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/pipe_in_jig_zpscd6242dc.jpg
[21:10:18] <Valen> theorbtwo: yes, that was the hard part there, how dare i not use a precise measurement when relating an anecdote
[21:10:18] <zeeshan> :D
[21:10:28] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/notch_check_zps9f861ae3.jpg
[21:10:51] <Valen> to "pass" welding they had to run a bead down a razor blade
[21:11:12] <zeeshan> thats easy
[21:11:14] <zeeshan> tig welder
[21:11:16] <zeeshan> ;D
[21:11:20] <Tom_itx> zeeshan, this is a lathe part too: http://www.flickr.com/photos/robertstory/sets/72157629312790321/comments/
[21:11:21] <Valen> zeeshan: i dunno that V looks pretty undercut to me
[21:11:31] <zeeshan> Valen: on purpose
[21:11:32] <jdh> no tig, just a cable and a bank of car batteries
[21:11:37] <zeeshan> i wanted maximum penetration
[21:11:37] <CaptHindsight> just think about if you had to start out with no tools and go from stone age to a 1" perfect metal cube
[21:11:43] <zeeshan> undercut is acceptable
[21:11:52] <Valen> I want to make a book on that CaptHindsight
[21:12:00] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/v_reinforced_zpsd5344f83.jpg
[21:12:05] <Valen> "how to build a civilisation in 100 years or your money back!"
[21:12:06] <zeeshan> =D
[21:12:09] <CaptHindsight> Valen: neat
[21:12:20] <zeeshan> Tom_itx: damn
[21:12:30] <CaptHindsight> based on todays info, how fast could it be done?
[21:12:32] <Tom_itx> i did one on my sherline
[21:12:34] <zeeshan> that looks like a lot of facing and boring
[21:12:47] <Valen> nfi, would be a job of work to find out
[21:12:57] <Valen> I was thinking kickstarter
[21:13:13] <Valen> but you need to do stuff like, how do you mine iron
[21:13:16] <Valen> and nickel
[21:13:19] <Valen> and molybdinum
[21:13:36] <Valen> tungsten if you want light bulbs
[21:13:39] <CaptHindsight> is food delivered or caught?
[21:13:50] <Tom_itx> hunted
[21:13:59] <Valen> I was thinking how you start a colony basically
[21:13:59] <eric_unterhausen> I am cutting squares on my cnc lathe
[21:14:14] <Tom_itx> i like watching wild alaska
[21:14:18] <zeeshan> eric_unterhausen: broaching? :D
[21:14:26] <CaptHindsight> looking back it was amazing how much time was spent on just getting food
[21:14:29] <eric_unterhausen> grinding the outside
[21:14:30] <zeeshan> or that funy offset tool
[21:14:31] <Valen> start off with around 40 people, have a breeding plan to maintain diversity etc then grow from there to a ~ 1930's society
[21:14:38] <theorbtwo> Gingery, for crazier people...
[21:15:08] <CaptHindsight> so 35 managers and 5 workers
[21:15:29] <zeeshan> serious question
[21:15:32] <julby0> breeding plan: 39 women and me
[21:15:34] <Valen> I wonder if sea water extraction might be the best way to get everything other than steel and Al
[21:15:43] <zeeshan> i have a 3hp vfd do you guys think putting it in the same enclosure as all the stepper drivers is a bad idea?
[21:15:53] <Valen> I was thinking you could also use it as your zombie survival handbook
[21:16:09] <Valen> or robopocalypse
[21:16:11] <eric_unterhausen> zeeshan, depends on your stepper ps
[21:16:15] <Valen> you know, choose your own disaster
[21:16:18] <zeeshan> ps?
[21:16:20] <zeeshan> power supply?
[21:16:20] <CaptHindsight> why do zombies need to survive? :)
[21:16:23] <eric_unterhausen> yes
[21:16:28] <zeeshan> im using 72v 8amp switched supplies
[21:16:30] <theorbtwo> CaptHindsight: The pilgrims did that. That's most of why they almost starved.
[21:16:36] <zeeshan> 2 of em
[21:17:20] <theorbtwo> Valen: I rather doubt it? Has anybody managed to make seawater extraction pay off?
[21:17:59] <CaptHindsight> the problem with lots of tech like water extraction is paying for the large plant
[21:18:17] <CaptHindsight> that is how government projects pay off in the long run
[21:18:40] <Valen> not in comparison with a petrochemical powered global economy, but if your after 50 grams of tungsten to make light bulbs trekking a few hundred Km by foot and trying to mine is probably going to be harder than hurling electricity at the ocean ;->
[21:18:40] <CaptHindsight> but not for capitalist investors
[21:20:09] <CaptHindsight> maybe next time people will decide to do something about sociopaths, selfishness and greed
[21:21:57] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/C1E223E1-4C0C-4255-99C5-2590B91C1742_zpsdjuo7tvp.jpg
[21:22:00] <zeeshan> see that big ass vfd
[21:22:17] <zeeshan> for some reason i feel like itll destroy the signal coming from the parallel port to the control side of the stepper drivers
[21:22:21] <jdh> CaptHindsight: we elect them.
[21:22:30] <Valen> use shielded cable on it
[21:22:41] <zeeshan> yes
[21:22:44] <Valen> and look at an EMI filter on the power side of it if you have problems
[21:22:53] <zeeshan> but the very ends that connect to the stepper will have unshilded portion
[21:22:55] <Tom_itx> yeah your job is to make it all quiet
[21:23:05] <Valen> keep the distance from the pport to the stepper driver shortish
[21:23:15] <zeeshan> should i put a faraday cage around the vfd?
[21:23:16] <Valen> and thats not a paticularly weak signal anyway so should be ok
[21:23:18] <Valen> nah
[21:23:40] <zeeshan> okay ill put them on opposite ends of the enclosure
[21:23:47] <zeeshan> so they'll prolly end up having at least 12" of space
[21:23:48] <CaptHindsight> jdh: gullible
[21:23:55] <Valen> its when you have a limit switch line thats connected to 6 switches running around the whole mill that you have issues
[21:24:07] <Valen> keep the distance from the pport itself to the stepper driver short if you can
[21:24:23] <Valen> and i belive that pport cables can come in shielded flavours?
[21:24:28] <zeeshan> this thing will have 4 limit switches
[21:24:36] <zeeshan> proximity inductive kind
[21:24:45] <Valen> thats where you are more likley to have noise issues
[21:24:54] <zeeshan> so ill get nuisance tripping?
[21:24:58] <Valen> the wire is the antenna, the longer the antenna the more noise it recieves
[21:25:06] <Valen> possibly
[21:25:07] <CaptHindsight> zeeshan: big reprap? :)
[21:25:10] <zeeshan> yea but those will be wired using alarm cable
[21:25:12] <zeeshan> which is shielded
[21:25:14] <Valen> depends on the phase of the moon
[21:25:48] <zeeshan> CaptHindsight: lathe
[21:26:54] <CaptHindsight> was the ML server stuck, I just got a dozen from 12 hours ago
[21:27:17] <zeeshan> do they make some sort of tool
[21:27:22] <zeeshan> to measure noise
[21:27:23] <CaptHindsight> must be mine they are all hours apart
[21:27:35] <zeeshan> basically a coil connected to an oscilliscope? :)
[21:28:40] <Valen> i wouldn't worry about it until you have a problem with it
[21:28:49] <zeeshan> i'd hate to have to remake the enclosure :{
[21:28:53] <Tom_itx> i used shielded wire on everything
[21:29:05] <CaptHindsight> http://www.bloomberg.com/news/2014-01-28/customs-drone-fleet-grounded-after-predator-goes-down.html
[21:29:16] <zeeshan> shielded wire doesnt shield the ends of the wire that go into the driver or breakout board though
[21:29:33] <Tom_itx> no but it dies there
[21:29:39] <zeeshan> from what ive seen most people use literally aluminum foil wrapped around their wires
[21:29:47] <zeeshan> and on top of that there is a pvc/plastic jacket
[21:29:53] <Tom_itx> ground one end or you'll get ground loops
[21:30:07] <zeeshan> http://i1274.photobucket.com/albums/y437/inchoice/1_zps3b02bbf0.jpg
[21:30:08] <zeeshan> that stuff
[21:30:18] <Tom_itx> i got a spool of shielded wire for my steppers
[21:30:34] <zeeshan> ground one end to the chassis?
[21:30:40] <Tom_itx> yes
[21:31:01] <Valen> ideally you want all the grounds in your system to be a star
[21:31:06] <CaptHindsight> flying cnc machines
[21:31:21] <zeeshan> star as in meet together at one point?
[21:31:25] <Valen> IE they all come back to one point
[21:31:26] <zeeshan> in a star pattern?
[21:31:27] <Tom_itx> similar to what you posted
[21:31:27] <Valen> with no loops
[21:31:29] <Tom_itx> only more wires
[21:31:30] <zeeshan> ah
[21:31:42] <Tom_itx> zeeshan all grounds come back to a single point
[21:31:51] <Tom_itx> not point to point to point
[21:31:51] <zeeshan> see the stepper casings also have a ground
[21:31:58] <zeeshan> i was going to ground that on the chassis too
[21:32:08] <zeeshan> i have zero experience with grounding control wire ;p
[21:32:16] <Valen> dont worry about it too much
[21:32:29] <Tom_itx> yeah, not unless you have noise problems
[21:32:31] <Valen> just ground one end of stuff ;->
[21:32:34] <zeeshan> okay
[21:32:40] <Valen> odds are you will be fine ;->
[21:32:53] <zeeshan> i just know this type of vfd is really noisey
[21:32:58] <zeeshan> you can hear it.
[21:33:05] <Valen> we had a VFD that sprayed so much noise the neighbours would complain about their radios getting bad
[21:33:06] <zeeshan> it runs at like 14khz
[21:33:06] <CaptHindsight> the suggestions just makes things more reliable
[21:33:13] <zeeshan> hahah
[21:33:21] <Valen> didn't bother our linear scale based servo system
[21:33:34] <zeeshan> im sure one day the hydro company is going to be pissed at me
[21:33:40] <Valen> and that was only TTL not differential drive from the scales
[21:33:42] <zeeshan> running 3 vfds together with no line reactors
[21:33:52] <zeeshan> :)
[21:34:01] <Valen> if they have power factor correction on the inputs then that should be ok
[21:34:07] <zeeshan> industrials/commercial places get OWNED by the power company for that
[21:34:13] <Valen> some of them will even the cheap ones because they can pull more power
[21:34:25] <Valen> they also pull eleventy billion jiggawatts
[21:34:45] <zeeshan> okay here's one more twist to the enclosure
[21:35:06] <zeeshan> i'd like to also on the back face of the enclsore across where all the vfds, breakoutboard, index pulse card, stepper drivers are mounted
[21:35:16] <zeeshan> i'd like to mount a motherboard there
[21:35:31] <zeeshan> and it's power supply. and a sata hd
[21:35:41] <Valen> hard part of that is mounting pci cards
[21:35:47] <zeeshan> no pci cards
[21:35:52] <Valen> (yet)
[21:35:53] <zeeshan> it's got onboard video and parallel port
[21:36:08] <Tom_itx> zeeshan, here's my sherline control pannel: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[21:36:20] <Tom_itx> maybe a bit overkill
[21:36:29] <Tom_itx> hidden in the door heatsink are the gecko drivers
[21:37:03] <zeeshan> your website is getting ddos
[21:37:04] <zeeshan> ed
[21:37:05] <zeeshan> lol
[21:37:10] <zeeshan> taking forever to load pics ;p
[21:37:16] <Tom_itx> ahh, hang on
[21:37:21] <Tom_itx> it's my friggin router
[21:39:41] <zeeshan> read the msds sheets for even the "non toxic coolants"
[21:39:45] <zeeshan> they have some nasty chemicals in there..
[21:39:46] <os1r1s> zeeshan: I thought it was better about the fog stuff :(
[21:39:53] <zeeshan> well you're atomizing it
[21:40:01] <jdh> http://en.wikipedia.org/wiki/Lipid_pneumonia
[21:40:02] <zeeshan> so you're going to breath it easier
[21:40:16] <os1r1s> Bummer. Guess I'll just stick with air
[21:40:23] <zeeshan> either use flood coolant or air.
[21:40:58] <os1r1s> Flood isn't an option for me, so air it is :)
[21:42:30] <zeeshan> Tom_itx: did you make those power supplies?
[21:43:01] <zeeshan> use photobucket!
[21:43:14] <Tom_itx> Valen, i got one but i need to work on the setup
[21:43:20] <Tom_itx> i had to put the old one back in
[21:43:34] <Valen> lol
[21:43:34] <Tom_itx> haven't had time to mess with it
[21:43:54] <Valen> get your new one working, the internet will hold a celebatory bbq of it
[21:44:06] <Tom_itx> yup
[21:44:08] <Valen> IE will all gether to burn your old one with fire
[21:44:08] <zeeshan> Tom_itx: how deep is that enclosure
[21:44:35] <Tom_itx> about 7.5"
[21:44:46] <zeeshan> and are you using nylon or some sort of standoffs for mounting your pcb boards
[21:44:58] <Tom_itx> brass pc standoffs
[21:45:06] <zeeshan> im so paranoid
[21:45:09] <Tom_itx> i should use those mesa mounts
[21:45:22] <zeeshan> im going to throw mylar film on top of my aluminum plate
[21:45:40] <zeeshan> i have tons of scrap pieces from that eaton job
[21:45:41] <Tom_itx> i got the box off ebay for next to nothing
[21:45:58] <Valen> mesa have mounts?
[21:46:20] <Tom_itx> sure do
[21:46:27] <Tom_itx> i found something else i wanted to get...
[21:46:32] <Valen> are they different in any way from mbo mounts?
[21:46:34] <Tom_itx> screw terminal power strips
[21:46:50] <Tom_itx> for the box rail mounts... i forget what they're called
[21:47:18] <zeeshan> http://www.thomasnet.com/articles/image/standoff.jpeg
[21:47:24] <zeeshan> think those are overkill? :p
[21:48:18] <Tom_itx> a bit
[21:48:43] <Tom_itx> Valen, DIN rail mounts
[21:49:03] <Tom_itx> and their common block are both listed at the top of their daughter card page
[21:49:23] <zeeshan> im so used to designing enclosures for 600v
[21:49:34] <zeeshan> im thinking my puny little 110v/220v needs the same requirements
[21:49:53] <zeeshan> infact, the pcbs dont even see higher than 12v
[21:50:20] <zeeshan> so 1/4" stand off would be more than adequate without needing any mylar.
[21:51:32] <Tom_itx> http://www.ebay.com/itm/RITTAL-AE1380-ENCLOSURE-STEEL-GREY-/121245256375?pt=LH_DefaultDomain_0&hash=item1c3ac7cab7
[21:51:37] <Tom_itx> that's the enclosure
[21:51:42] <Tom_itx> but i didn't pay near that for it
[21:51:58] <zeeshan> i need 10" deep minimum
[21:51:59] <zeeshan> ;[
[21:52:09] <Tom_itx> they've got em
[21:52:12] <os1r1s> Tom_itx: I didn't know you ran a sherline.
[21:52:15] <zeeshan> ill look through it
[21:52:56] <Tom_itx> os1r1s mostly for playing
[21:53:26] <os1r1s> Tom_itx: My two ... http://mounicou.com/cnc/cncenc.jpg
[21:53:37] <zeeshan> cute
[21:53:38] <zeeshan> haha
[21:53:39] <os1r1s> Though I just replaced the motor on the Taig with a sherline motor
[21:53:47] <Tom_itx> i think i've seen those
[21:53:56] <os1r1s> Tom_itx: Prolly
[21:54:01] <zeeshan> os1r1s: why cant you use flood coolant?
[21:54:07] <zeeshan> all you need is a base
[21:54:14] <zeeshan> and a bucket on the buttom of your table
[21:54:16] <os1r1s> Tom_itx: I want to build one of the toolchangers for the mill
[21:54:36] <os1r1s> zeeshan: Too much risk/mess for an indoors/upstairs workshop
[21:54:51] <zeeshan> did you build those enclosures?
[21:54:52] <os1r1s> Though I may reconsider at some point :P
[21:54:55] <os1r1s> zeeshan: Yeah
[21:54:59] <zeeshan> they're fucking nice!
[21:55:05] <os1r1s> zeeshan: 1/4 lexan panels
[21:55:06] <jdh> that's a lot of extrusion
[21:55:14] <os1r1s> Should handle impact well if it gets any
[21:55:28] <zeeshan> its not like you're going to be running 2" end mills
[21:55:29] <zeeshan> :P
[21:55:36] <zeeshan> but those are nicely built.
[21:55:38] <os1r1s> haha. Right
[21:55:46] <os1r1s> I'm more worried about work flying
[21:55:52] <os1r1s> zeeshan: Thx
[22:00:28] <CaptHindsight> anyone ever weld ~1mm aluminum with a MIG? extra points for not using a spool gun
[22:00:44] <Tom_itx> nope
[22:00:51] <zeeshan> almost impossible mate
[22:00:55] <Tom_itx> i saw 2 pop cans welded together though
[22:00:57] <Tom_itx> using tig
[22:01:05] <CaptHindsight> yeah TIG
[22:01:09] <Tom_itx> :)
[22:01:17] <zeeshan> tig can handle that easily
[22:01:27] <zeeshan> mine goes down to 5amp which means you can weld down to .005 thick metal
[22:01:30] <CaptHindsight> I never tried to see how light on aluminum I can go
[22:01:40] <CaptHindsight> with a MIG
[22:01:41] <zeeshan> you might be able to use aluminum solder
[22:01:56] <CaptHindsight> TIG is the right tool
[22:02:00] <zeeshan> http://www.youtube.com/watch?v=hHvrE1Cd5Eg
[22:02:01] <Tom_itx> ok i gotta restart something here... this is ridiculous
[22:02:01] <zeeshan> that stuff
[22:05:13] <Tom_itx> zeeshan, try that page now
[22:06:06] <CaptHindsight> http://www.harborfreight.com/8-piece-low-temperature-aluminum-welding-rods-44810.html
[22:06:27] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/ast4.jpg
[22:06:37] <zeeshan> the sheet metal pieces not the fitting (bottom weld)
[22:06:49] <zeeshan> was in 1.5 mm aluminum
[22:07:03] <zeeshan> Tom_itx: still slow :{
[22:07:07] <CaptHindsight> http://www.durafix.com/
[22:07:16] <zeeshan> but i've loaded 3 of the pictures i was interested in
[22:07:22] <Tom_itx> refresh it and see
[22:07:30] <Tom_itx> should be alot better now
[22:07:56] <zeeshan> basically
[22:07:59] <zeeshan> it loads half the picture
[22:08:00] <zeeshan> and then stalls
[22:08:01] <CaptHindsight> also http://www.alumiweld.com/
[22:08:02] <Tom_itx> meh, it's still marginal
[22:08:52] <zeeshan> you found that heat sink at a scrap yard?
[22:08:58] <zeeshan> what kind of scrap yards are around your area?!?!
[22:08:58] <Tom_itx> yup
[22:09:00] <zeeshan> haha
[22:09:05] <zeeshan> that's a good find
[22:09:07] <Tom_itx> aircraft scrap
[22:09:15] <Tom_itx> alot of aluminum
[22:09:27] <zeeshan> do you remember how much that extrusioin ended up costing?
[22:09:27] <Tom_itx> 8' stick of it
[22:09:35] <Tom_itx> by the pound
[22:09:38] <zeeshan> damn
[22:09:39] <Tom_itx> no not really
[22:09:48] <zeeshan> well aluminum is like 2bux a pound usually
[22:09:55] <CaptHindsight> http://www.alumiweld.com/faq.html
[22:10:10] <zeeshan> CaptHindsight: that alumiweld is that brand i've seen in a lot of youtube videos
[22:10:35] <CaptHindsight> lower cost than some of my TIG rods
[22:10:47] <zeeshan> if u have a tig
[22:10:50] <zeeshan> why are you brazing!
[22:10:56] <zeeshan> is it dc only?
[22:11:26] <CaptHindsight> no, I was just wondering if anyone tried to MIG light aluminum
[22:11:32] <zeeshan> ah
[22:11:41] <CaptHindsight> just to see how light they can go
[22:13:44] <zeeshan> curious question of the day
[22:13:55] <zeeshan> what's the largest cutting tool you guys own?
[22:14:10] <Valen> 90mm face mill i think
[22:14:12] <Tom_itx> damn. own or have used?
[22:14:16] <zeeshan> own
[22:14:23] <Valen> or the 15A bandsaw?
[22:14:27] <Tom_itx> well i'm out... i have a sherline now
[22:14:29] <CaptHindsight> http://www.youtube.com/watch?v=U1gWaGZ-nks starts around 2:00 TIG Welding Pop Cans!!
[22:14:34] <zeeshan> it has to be a cutting tool
[22:14:37] <zeeshan> not a machine ;p
[22:14:46] <Valen> the blade from the bandsaw?
[22:14:48] <zeeshan> haha
[22:15:25] <Tom_itx> overall probably a 6" shell mill or the 2 & 3" insert cutter drill bits we used
[22:15:40] <zeeshan> gotta own em ;[
[22:15:42] <Valen> Tom_itx: (I wouldn't want to use it on the 24Krpm spindle we have now though lol)
[22:15:57] <Tom_itx> the bits were for titanium parts
[22:16:16] <zeeshan> mine is a 2.5" drill bit
[22:16:22] <zeeshan> it came with my lathe lol
[22:16:25] <skunkworks> we have a 12" facing mill
[22:16:28] <zeeshan> i don't think ill ever use it
[22:16:35] <zeeshan> 12" face mill. holy cow
[22:17:24] <Tom_itx> for the part 3 from the left in the Titanium section: http://clearwateren.com/gallery.php
[22:17:28] <skunkworks> here is only a 6"
[22:17:35] <skunkworks> http://www.youtube.com/watch?v=1a0YpKfSGE8
[22:17:56] <Tom_itx> those are drilled thru now
[22:17:57] <skunkworks> (yes - I am running it too slow...)
[22:17:59] <zeeshan> is that on a horizontal mill
[22:18:01] <zeeshan> or lathe
[22:18:04] <skunkworks> mill
[22:18:06] <zeeshan> that thing is just eating metal.
[22:18:09] <Valen> I find the ceramic stuff cooler
[22:18:16] <zeeshan> looks like a .125 deepth of cut
[22:18:25] <skunkworks> http://www.youtube.com/watch?v=39q6kvrSBSk
[22:18:28] <CaptHindsight> I bought a Cincinnati mill a few years ago and the seller threw in a bunch of face mills that size
[22:18:33] <Valen> http://www.youtube.com/watch?v=c1K5QjR3hyU
[22:18:51] <skunkworks> don't remember - I was just squaring up some blocks
[22:19:06] <zeeshan> rofl at that tap
[22:19:07] <zeeshan> wtf
[22:19:08] <zeeshan> hahaha
[22:19:15] <zeeshan> what is that a 2" tap
[22:19:24] <skunkworks> only 1"
[22:19:29] <zeeshan> looks huge for some reason
[22:19:59] <zeeshan> Valen: inconel machining is my choice of porn
[22:20:00] <Valen> "thats what he said"
[22:20:13] <CaptHindsight> skunkworks: is that home or at work? :)
[22:24:47] <CaptHindsight> http://www.youtube.com/watch?v=objyMqAHUNU same machine with pallet transfer
[22:25:02] <CaptHindsight> that is a beast
[22:25:55] <Tom_itx> one of the okumas had a 2 pallet changer
[22:26:19] <Tom_itx> 2 toumbstones mounted to them
[22:38:15] <skunkworksnook> CaptHindsight: dads retirement sanity
[22:40:03] <CaptHindsight> skunkworks: what kind of electrical service does he have?
[22:43:54] <PetefromTn> We talkin' machine porn here LOL
[22:44:25] <skunkworksnook> 240 3phase
[22:45:09] <PetefromTn> Whats the travels on that K and T monster?
[22:46:07] <skunkworksnook> 38x36x24
[22:46:29] <PetefromTn> Nice...it actually looks even larger than that.
[22:48:07] <skunkworksnook> it comes in handy
[22:49:35] <PetefromTn> No doubt.
[22:49:51] <PetefromTn> Have you made anything interesting on it lately?
[22:51:18] <skunkworksnook> http://imagebin.org/287781 < his new toy
[22:51:45] <skunkworksnook> I have not - new dad
[22:51:59] <CaptHindsight> http://imagebin.org/289642 adding steppers this week
[22:54:00] <skunkworksnook> cool
[22:54:07] <PetefromTn> Nice man I was looking at those Matsuura's before I got my machine. Nice mills.
[22:54:37] <PetefromTn> I have heard parts can be really expensive tho.
[22:55:04] <skunkworksnook> few bugs - but the control boots. might run it that way
[22:55:52] <skunkworksnook> otherwise pretty cheap conversion
[22:56:15] <CaptHindsight> steel leadscrew in an aluminum body/nut
[22:56:43] <CaptHindsight> I wonder how long it will hold up at 5mm/sec?
[23:00:29] <CaptHindsight> maybe add a synthetic felt with oil to keep it lubricated
[23:03:56] <CaptHindsight> http://www.use-enco.com/CGI/INPDFF?PMPAGE=524&PMITEM=505-6694 I wonder what the TPI is for the screws in the mini sherline mills?
[23:05:38] <CaptHindsight> 1/4-20 with aftermarket upgrades to 1mm pitch
[23:05:58] <Tom_itx> mine are 1/4 20 still
[23:06:07] <Tom_itx> Z is bigger but same pitch
[23:06:24] <os1r1s> PetefromTn: Where in TN?
[23:06:32] <Tom_itx> i can get 80 ipm
[23:06:36] <Tom_itx> rapid
[23:07:18] <PetefromTn> os1r1s: I am in Maryville, Just south of Knoxvegas...
[23:07:26] <CaptHindsight> I will only have a 12mm travel
[23:08:34] <CaptHindsight> shooting for only 12 ipm with a 80 tpi screw
[23:08:46] <os1r1s> PetefromTn: Cool. I'm near Memphis.
[23:09:58] <PetefromTn> nice man thats pretty damn far away tho LOL
[23:10:20] <CaptHindsight> Knoxvegas?
[23:10:42] <CaptHindsight> gambling, dancing girls?
[23:12:40] <jdh> moonshine and dancing girls... some even have teeth.
[23:13:18] <CaptHindsight> fancy
[23:22:41] <os1r1s> PetefromTn: I'm familiar with the area. Been out there a few times and through there going to Ashville
[23:23:20] <PetefromTn> Oh yeah some real winners around here I mean Hey I live here right LOL
[23:23:26] <CaptHindsight> http://www.mscdirect.com/browse/?navid=12106240+4288105550 $24-100 for 0.2mm end mills!?
[23:23:33] <PetefromTn> Yeah thats a hike.
[23:23:50] <os1r1s> PetefromTn: Actually I went through Maryville last time I ran the tail
[23:23:53] <CaptHindsight> Tom_itx: where do you get your small end mills for the sherline?
[23:24:05] <PetefromTn> Evil road..
[23:24:40] <PetefromTn> Dropped my FZR1000R there a couple years back luckily I survived and the bike only needed a new mirror and windscreen.
[23:26:42] <os1r1s> PetefromTn: I think this was a spot on the tail where we stopped ... http://gallery.mounicou.com/Travel/Asheville-2010/i-fCjcVRK/0/L/IMG_0222-L.jpg
[23:27:09] <PetefromTn> Yup the overlook. Been there many times.
[23:27:25] <PetefromTn> It is maybe ten to twelve minutes from my house LOL.
[23:27:48] <os1r1s> That was when they had closed one end due to the landslide. So traffic was light
[23:28:37] <PetefromTn> I went thru there with the Fiero Club awhile back before I sold my car to get my wife a newer SUV. LOL
[23:30:13] <PetefromTn> Spent much of the afternoon playing with CamBam trying to learn my way around the program. got a bunch of things working right but still cannot figure out how to turn coolant on and off LOL.
[23:30:19] <CaptHindsight> I was just reading about the Tail the other day. Why is it considered so treacherous?
[23:30:35] <CaptHindsight> land slides?
[23:30:40] <eric_unterhausen> because people are stupid
[23:31:03] <eric_unterhausen> I'm a good driver == I can floor the gas pedal to most people
[23:32:00] <eric_unterhausen> there is a road in California that was fine until all the motorcyclists and car drivers use it to show how badly they drive
[23:32:15] <eric_unterhausen> mullholland canyon I think
[23:32:50] <Jymmm> what about mulholland drive?
[23:32:55] <eric_unterhausen> that's it
[23:33:18] <eric_unterhausen> there's a guy that makes a living off of people crashing on it
[23:33:29] <Jymmm> Nah, more of a constant collection of stupidity for the cops is all.
[23:33:49] <PetefromTn> The road is really tight and twisty. 118 turns in 11 miles.
[23:33:51] <Jymmm> Especially being just Northof Hollywood
[23:34:05] <os1r1s> PetefromTn: I like the tree of shame
[23:34:17] <PetefromTn> The biggest issue is there is NO runoff area anywhere so if you do manage to lose it like I did you wind up going down a cliff into the trees..
[23:34:45] <PetefromTn> If you go off on the high side of the cliff you still hit trees.
[23:35:11] <PetefromTn> The NC side of the road is also not that smooth and can cause issues with traction.
[23:35:23] <eric_unterhausen> haha, the cops sit in the same place as the utube guy
[23:35:35] <PetefromTn> People are air lifted out of there almost daily during the summer.
[23:36:40] <eric_unterhausen> bugatti driver can affort the ticket I guess
[23:36:48] <PetefromTn> I was actually doing pretty good but lost the front end for just a second and by the time I gathered it up again I was going across the damn median in the next turn. nearly hit a van and ran into the grass on the other side.
[23:37:03] <PetefromTn> I was pretty lucky considering.
[23:37:15] <PetefromTn> The funny thing is I was not going all that fast.
[23:37:29] <PetefromTn> It is just a complex road.
[23:37:51] <PetefromTn> It is not really all that fun to ride on it with a bike because you are constantly working to maintain your line.
[23:38:26] <eric_unterhausen> if you lose it on mulholland, you get to relive the first scene from mulholland falls
[23:38:38] <PetefromTn> There are some GORGEOUS roads around here that are long and twisty but have kinda fast smooth arcs that are much more enjoyable to ride on.
[23:39:13] <os1r1s> PetefromTn: The skyway is nice in that respect
[23:39:23] <os1r1s> Some fast sweepers
[23:39:25] <eric_unterhausen> there is a road near my mother's in Virginia that has turns so tight that it's a bit scary
[23:39:41] <PetefromTn> I live right near the foothills parkway..it is quite nice and the view is pretty incredible.
[23:40:31] <PetefromTn> There are lots of roads like that around here, the dragon is just one of them and is the longest most famous one.
[23:40:44] <PetefromTn> People come from around the world to ride this road believe it or not.
[23:42:16] <CaptHindsight> http://img139.imageshack.us/img139/8928/dangerousroads5kc3.jpg
[23:43:17] <PetefromTn> That actually looks like fun LOL..
[23:43:48] <CaptHindsight> http://www.zuzafun.com/dangerous-roads the last one is crazy
[23:44:04] <CaptHindsight> I wonder where that bridge is
[23:44:19] <PetefromTn> Just searched about the coolant flow in CamBam. I guess it is not setup for it. You have to make an add on Machining operation that puts a header or footer under each machining op to get it done.
[23:45:17] <PetefromTn> Either that or mod the post processor to install the code permanently.
[23:45:24] <Valen> https://maps.google.com.au/maps?q=Little+Brown+Mountain,+Bemboka,+New+South+Wales&hl=en&ll=-36.608431,149.476032&spn=0.059046,0.132093&sll=35.131521,-81.405085&sspn=0.030079,0.066047&oq=Brown+Mountain+bemb&hnear=Little+Brown+Mountain&t=m&z=14 is the exciting road we have when we go on holidays
[23:45:31] <Valen> it drops about a km over that distance ;->
[23:46:21] <PetefromTn> Kinda odd that a Cam program does not have native coolant support huh.
[23:46:40] <eric_unterhausen> huh
[23:47:16] <PetefromTn> uh huh
[23:47:30] <eric_unterhausen> huh is the best word ever
[23:47:54] <PetefromTn> you are some kinda smartass huh
[23:48:04] <eric_unterhausen> huh
[23:48:25] <Jymmm> Better to be a smartass than a dumbass.
[23:48:45] <eric_unterhausen> i dunno, lots of times there isn't much space between
[23:49:00] <Jymmm> eric_unterhausen: Huh?
[23:49:06] <Jymmm> ;)
[23:50:02] <CaptHindsight> Valen: streetview works on that Hywy
[23:51:30] <CaptHindsight> but the cars are on the wrong side of the road :)
[23:51:36] <PetefromTn> I would imagine there are some beautiful sights around there LOL
[23:52:28] <CaptHindsight> I wish streetview had a play button where it would just drive you down the road without having to click the buttons
[23:52:48] <PetefromTn> That would be fun. take a drive from your easy chair.
[23:53:21] <eric_unterhausen> ya, driving would be nice
[23:53:31] <PetefromTn> I wonder if the lookout on foothills parkway lets you go up there on streetview.
[23:53:38] <eric_unterhausen> especially since it doesn't always drop you where you put the circle
[23:54:15] <eric_unterhausen> when I was a teenager, I was following a friend and did a 180 on a steep mountain road.
[23:54:27] <eric_unterhausen> had to drive to the bottom because there was no place to turn around
[23:55:00] <eric_unterhausen> turns out my friends car had better tires
[23:55:26] <eric_unterhausen> still can't believe I was so lucky that I didn't hit anything
[23:56:14] <eric_unterhausen> only way to do a u turn is at speed because the road is too narrow otherwise
[23:59:38] <PetefromTn> If you google yourself down the foothills parkway in tennessee starting from the walland hwy towards the dragon there are some amazing lookouts that you can view along the way and there is a lookout on I think the third one that has the lookout tower. I am trying to get there now to see if you can view it.
