[00:26:54] <zeeshan> https://www.youtube.com/watch?v=-TjqtXB8BtY
[00:27:00] <zeeshan> this is what i imagine jt-shop to look like
[00:27:01] <zeeshan> :-)
[00:27:37] <XXCoder> yo
[00:28:31] <XXCoder> is he suciding
[00:28:51] <XXCoder> ah
[00:28:57] <XXCoder> blower mode lol
[00:32:24] <XXCoder> zeeshan: hows things
[00:32:43] <zeeshan> things are good
[00:32:48] <zeeshan> they'd be better if this stupid clutch pedal
[00:32:50] <zeeshan> would design itself
[00:32:54] <XXCoder> lol
[00:33:01] <zeeshan> its a completely 3d part
[00:33:05] <zeeshan> with not much reference planes
[00:33:12] <XXCoder> fun
[00:33:23] <XXCoder> whats place where most points are on common plane?
[00:33:57] <zeeshan> http://i.ebayimg.com/00/s/ODQ1WDEwMjQ=/z/0bsAAOxyA7tSZDP1/$T2eC16dHJF4FFk2D,6GFBSZDP0JCgw~~48_35.JPG
[00:34:14] <XXCoder> the pedal only
[00:34:33] <zeeshan> its been bent in 2 diff planes
[00:34:37] <zeeshan> compound angle
[00:34:42] <zeeshan> and done twice
[00:34:45] <XXCoder> its good idea to just do the complex side
[00:34:54] <XXCoder> then flip it over and mill other side
[00:35:05] <XXCoder> thyen finally cut off the holder tab
[00:37:09] <zeeshan> i need a faro arm! :D
[00:37:18] <XXCoder> whatsnit
[00:38:11] <zeeshan> for reverse engineering
[00:38:12] <zeeshan> brb
[01:15:53] <XXCoder> zeeshan: what IS faro arm?
[01:24:43] <CaptHindsight> zeeshan: JT-Shop has pics up on his site of his shop
[01:25:40] <CaptHindsight> http://gnipsel.com/shop/machine-shop.xhtml
[01:26:28] <archivist> XXCoder, just a form of cmm, slightle less accurate than others but flexible http://www.faro.com/home
[01:27:07] <XXCoder> NICE
[01:27:10] <XXCoder> er nice
[01:27:13] <CaptHindsight> archivist: up early or late for you?
[01:27:22] <archivist> stacked encoders so the inaccuracies add
[01:27:40] <XXCoder> archivist: though did you hear of using xbox sensor to do it?
[01:27:44] <XXCoder> forgot what its called :P
[01:27:47] <archivist> 7AM you are late to bed :)
[01:28:03] <CaptHindsight> calling it an early night
[01:28:09] <CaptHindsight> hasta banana
[01:28:18] <archivist> nay thing by M$ is a toy so no
[01:28:24] <archivist> anything
[01:28:43] <XXCoder> still, it may do in pinch if dont care 100% on acurracy
[01:29:04] <XXCoder> http://www.instructables.com/id/3D-Scan-and-duplicate-yourself-or-anything/
[01:29:09] <XXCoder> kinecg
[01:29:14] <archivist> the thing about the faro arm is you can put it on the floor and measure inside a car
[01:30:03] <XXCoder> fancy.
[01:30:19] <archivist> XXCoder, that result looks only 60% not close enough to 100%
[01:30:43] <XXCoder> yeah
[01:30:53] <XXCoder> still enough to do some basic stuff
[01:31:06] <XXCoder> then polish the model to what you like
[01:32:06] <archivist> and there is a basic rule of measurement that in order to measure to 1% your equipment must be 10 times better, .1%
[01:36:06] <archivist> the reason for that is there are other uncertainties to add, eg length needs you to think about temperature, contact pressure and axis of measurement on axis of item, etc
[01:52:23] <XXCoder> archivist: yeah noticed it
[02:02:22] <archivist> wich reminds me, I have to make some styli for my measuring machine http://www.archivist.info/cnc/screw_error/NPL/fig10.jpg
[02:02:27] <archivist> which
[02:14:06] <XXCoder> cool
[02:14:13] <XXCoder> tyou have a cmm?
[02:14:51] <Deejay> moin
[02:16:21] <XXCoder> hey
[02:17:35] <archivist> XXCoder, only home made
[02:17:45] <XXCoder> nice
[02:18:08] <archivist> mk1 http://www.collection.archivist.info/searchv13.php?searchstr=travelling
[02:18:30] <archivist> mk2 needs finishing and pictures taken
[02:19:48] <archivist> mk1 is a pain to read the vernier when measuring a long screw
[02:20:08] <archivist> better toy is http://www.archivist.info/cnc/screw_error/lamp_screw.php
[02:20:17] <XXCoder> so thats your speciality, figuring design?
[02:21:06] <archivist> often have to measure old items to make new replacements
[02:22:20] <XXCoder> I guess for unknown items
[02:22:27] <XXCoder> like part so old nobody has plans for it
[02:22:39] <archivist> I am modifying http://www.collection.archivist.info/searchv13.php?searchstr=citizen adding the optics from the swift microscope and a digital scale
[02:22:55] <archivist> and a camera I hope
[02:23:56] <archivist> eg plastic gears that have gone brittle and lost most of the teeth
[02:26:26] <XXCoder> interesting
[05:01:00] <SpeedEvil> archivist: find a dentist
[05:28:41] <RyanS> https://www.youtube.com/watch?feature=player_detailpage&v=J0o3W4_LRBw#t=261 I thought an involute curve was important? but taps cut linear teeth
[05:35:22] <archivist> taps are a bodge, look at the title "Primitive"
[05:38:59] <archivist> no way he will get a good gear as he has not geared the blank to the spindle
[05:42:12] <archivist> the form will be involute on the gear, as the tap is a rack form and that does cut involute
[05:43:21] <archivist> the hobbing process "generates" a curve
[05:46:25] <RyanS> could a small CNC hobber work, it would be mechanically simpler to build
[05:47:31] <archivist> erm yes http://www.collection.archivist.info/searchv13.php?searchstr=barber+colman
[05:47:42] <archivist> with linuxcnc too
[05:49:23] <archivist> possibly a 1940s machine, retrofitted last year
[07:03:23] * archivist slaps Jt with http://gnipsel.com/linuxcnc/arcgen/files/arcgenl.py
[07:04:57] <archivist> pointed at from http://gnipsel.com/linuxcnc/arcgen/qcad06.html
[07:58:48] <jthornton> is something broken?
[08:01:57] <SpeedEvil> ?
[08:02:05] <SpeedEvil> Many things are broken.
[08:05:45] <archivist> jthornton, yes
[08:07:24] <archivist> at least two links dead on page http://gnipsel.com/linuxcnc/arcgen/qcad06.html
[08:39:53] <JT-Shop> lol I zipped the files and forgot to change the link
[08:56:12] <_methods> hahah regular coffee cup near mill equals new flavor coffee
[08:56:21] <_methods> not a good flavor either
[08:59:40] <SpeedEvil> You should change your coolant
[09:04:54] <_methods> hahah
[09:05:03] <_methods> i don't think starbucks will be buyin me out any time soon
[09:05:40] <SpeedEvil> Hmm. Oddly, I can't find any coolants listing 'richer smoother taste' as a benefit.
[09:05:46] <SpeedEvil> Clearly a gap in the market
[09:07:56] <_methods> haha right
[09:08:04] <_methods> just pull the lock line over to your mug
[09:08:10] <_methods> and hit the coolant button
[09:17:00] <archivist> had a hard life http://www.ebay.co.uk/itm/HARDINGE-CAPSTAN-LATHE-REPETITION-NOT-BRITAIN-TURRET-AUTO-FEED-OR-CNC-/121617359842
[09:17:27] <jthornton> archivist, should be fixed now
[09:18:27] <SpeedEvil> archivist: 'We should sandblast it to clean it up' 'But I've only got gravel'
[09:19:10] * archivist slaps jthornton with http://gnipsel.com/linuxcnc/arcgen/files/arcgenl.py.zip
[09:40:52] <JT-Shop> 12 more holes to drill and tap then clean up on aisle 3
[10:36:34] <JT-Shop> https://www.youtube.com/watch?v=QlCJTUHg9vw
[10:36:44] <JT-Shop> a guy in NZ installing my air filter
[10:41:16] <Tom_L> nice one jt
[10:43:43] <Tom_L> anodizing looks good
[10:54:56] <JT-Shop> thanks, wish I was anodizing lol
[11:09:49] <JT-Shop> last hole to drill and tap YEA!
[11:14:40] <Tom_itx> JT-Shop you don't have yours set up yet?
[11:16:57] <JT-Shop> mine?
[11:17:08] <Tom_itx> your anodizing setup
[11:17:16] <JT-Shop> 90%
[11:25:36] <JT-Shop> I pretty much just have to fill the tanks and plug things in on the anodizing line
[11:26:17] <JT-Shop> now I have people wanting the only thing I don't have in stock lol
[11:26:34] <Tom_itx> air filters?
[11:27:41] <JT-Shop> no, the 17mm to B-Ball adapters
[11:29:26] <Tom_itx> job security
[11:29:46] <JT-Shop> I'll make some after my nap lol
[11:29:58] <Tom_itx> yeah you gotta have priorities!
[11:30:53] <JT-Shop> what a pretty table http://ibin.co/1y5p2NFKZX6N
[11:31:32] <archivist> what idiot would pay this much for a toy http://www.ebay.co.uk/itm/Lathe-for-Metal-PD400-CNC-Proxxon-24500-/181697964618
[11:31:38] <Tom_itx> are those trike parts too or something else?
[11:33:31] <JT-Shop> me?
[11:33:48] <Tom_itx> yeah
[11:34:16] <JT-Shop> I'm making 12 clamp ups for Briggs final assembly line here in PB and they are one of the parts
[11:35:01] <Rab> archivist, is that not a competitive price for a new CNC jeweler's lathe?
[11:35:06] <JT-Shop> the engine comes down the line on a pallet and when it gets to a clamp up the device picks the palled up a tiny bit and positions it in the same place every time for auto assembly machines
[11:36:56] <archivist> Rab, when I see thes proxon things up close a lot of plastic seems in evidence or some light alloy, note in that item they claim ball screws and mention the lead screw is acme
[11:37:08] <zeeshan> looks good JT-Shop :)
[11:38:36] <JT-Shop> thanks
[11:39:01] <pcw_home> Are those nema17 steppers?
[11:39:05] <Rab> archivist, I've only seen the Proxxon rotary tools, and while they do have a toy-like aspect they also show serious engineering and precision which puts them in a different class from e.g. Dremel.
[11:42:29] <Rab> I think the Proxxon lathe might be a poor choice for a general-purpose hobby lathe, but a reasonable choice for precision miniature fixtures in a laboratory setting.
[11:43:10] <Rab> I don't know who else services that sort of niche in 2015, but I'm sure they're not any cheaper.
[11:43:36] <archivist> write up is better on their own site http://www.proxxon.com/en/micromot/24500.php
[11:45:16] <archivist> Denford and EMCO I suppose are the eu competition
[11:47:07] <Rab> I wonder what the linear resolution is, and why they don't mention it.
[11:47:44] <syyl_ws> proxxon only makes better toys
[11:48:03] <archivist> some time ago I looked at another proxon and it too lacked proper specs
[11:48:35] <syyl_ws> a lot of ligh-alloy castings where they dont make any sense
[11:48:47] <syyl_ws> a die-cast tailstock for a lathe?
[11:48:53] <syyl_ws> with ribbed guideways?
[11:48:55] <archivist> ew
[11:48:57] <syyl_ws> seriously?
[11:49:31] <archivist> never been impressed when I saw anything of theirs up close
[11:49:46] <syyl_ws> they where smoking some heavy stuff when they design something..
[11:50:19] <syyl_ws> i have one of their rotary tools
[11:50:20] <archivist> except perhaps the dremel sizes wire brushes, but they throw wires in seconds too
[11:50:22] <syyl_ws> thats "ok"
[11:50:33] <syyl_ws> way better than a dremel
[11:50:38] <syyl_ws> but horrible underpowered
[11:50:52] <syyl_ws> but it refuses to die
[11:50:58] <syyl_ws> for now something about 10 years :D
[11:51:14] <syyl_ws> that tool doesnt owe me anything
[11:51:20] <syyl_ws> should be dead by 5 times :D
[11:51:32] <archivist> I use dremels and thrash them for hours
[11:51:55] <syyl_ws> ouch
[11:52:05] <syyl_ws> i am still looking for a nice biax diegrinder
[11:52:12] <syyl_ws> but they are a bit pricy...
[11:52:17] <Rab> Foredom > Proxxon > Dremel
[11:52:32] <syyl_ws> biax > ................... > Foredom > Proxxon > Dremel
[11:52:36] <syyl_ws> ;)
[11:53:15] <Rab> Is that an air tool, or do they offer electric?
[11:53:23] <syyl_ws> only air :\
[11:53:27] <syyl_ws> but indestructable :D
[11:55:50] <zeeshan> the only thing wrong with my dremel
[11:55:54] <zeeshan> is i blow up the cutting discs
[11:55:55] <zeeshan> :/
[11:56:26] <syyl_ws> go bigger! :D
[11:59:30] <Rab> zeeshan, use the fiberglass discs.
[12:00:30] <Rab> The thin discs are nice for fine cutting like slotting stripped screws, but they sure are annoyingly fragile.
[12:01:11] <zeeshan> thats like theonly time i use a dremel
[12:01:13] <zeeshan> for fine work
[12:01:14] <zeeshan> :P
[12:01:50] <Tom_itx> the center blows out of the fiberglass discs too easy
[12:02:47] <Tom_itx> zeeshan i can usually use a cutoff disk until it's worn down to next to nothing
[12:02:59] <Tom_itx> you must be pushing it too hard or tilting the blade
[12:03:06] <zeeshan> yea i know :P
[12:03:13] <zeeshan> they dont take any side load
[12:03:23] <Tom_itx> not designed to
[12:03:24] <zeeshan> but its hard to not do that
[12:03:26] <zeeshan> when it gets caught
[12:36:46] <renesis> rab: love how the kits ship with one fiberglass disc and a fuckin tube of the thin discs
[12:37:11] <Rab> renesis, haha yeah
[12:41:16] <archivist> dremel cant be all bad the engraving on these hands was done by dremel :) http://www.collection.archivist.info/archive/DJCPD/PD/2001/2001_07_13_Blacksmith_clock_hands/P1010116.JPG
[12:41:50] <Rab> wow
[12:42:16] <archivist> the new ones, not the ones copied
[12:43:47] <archivist> side v's are hand filed
[12:43:47] <renesis> they work, they spin and hold tools
[12:43:56] <renesis> but they like, eat themselves
[12:45:19] <renesis> like, either the motor kind of craps out, the control boards gives up its smoke, or the key button for the spindle lock wears down and its annoying to change tools
[12:46:45] <Rab> I wouldn't go that far. Spinning implies some sort of concentricity, hard to achieve with aluminum collets...same with tool holding.
[12:47:29] <archivist> I use the 3 jaw chuck accessory, and wear them out too
[13:09:51] <renesis> rab: youre doing it wrong
[13:10:17] <Rab> renesis, doing what.
[13:10:23] <renesis> concentricity happens when you put side loading on it and the axis gets locked into position by bearing irregularities
[13:11:01] <Rab> haha
[13:11:11] <renesis> its not completely a joke =(
[13:11:25] <Rab> I know, that's what makes it extra funny.
[13:12:32] <renesis> the work key thing pisses me off the most
[13:12:53] <renesis> my guess is they tried using steel bits and it just ripped itself apart instead of just getting more annoying
[13:13:12] <renesis> *worn
[13:15:14] <Rab> The button to hold the shaft?
[13:15:39] <renesis> yeah
[13:16:20] <renesis> prob 90% of the dremels were things at work, prob half of those the button wouldnt hold the spindle anymore
[13:17:17] <renesis> i know my dremel, i had it a few days and leaned into the button on accident while it was loaded, and that thing was never the same
[13:17:56] <renesis> it works but its clearly semi fucked, not close to new in functionality
[13:25:19] <Rab> Based on my mid-'80s Dremel, the button engages a triangular pot-metal spider. So there are three points in a rotation where you can immobilize the shaft.
[13:32:14] <renesis> mid 99s pot metal is probably not as awesome
[13:32:25] <renesis> er, 00s
[14:02:50] <CaptHindsight> the new season of Silicon Valley starts today
[14:10:16] <MrSunshine> what is that about ?
[14:11:11] <renesis> cubicle humor in a startup setting
[14:11:42] <renesis> rly i dunno i hasnt seen it
[14:12:50] <zeeshan> anyone here design a hydraylic cylinder before
[14:17:02] <Tom_itx> hah
[14:17:10] <Tom_itx> you gonna make a drawbar for your spindle?
[14:21:33] <_methods> i hear the first 4 episodes of game of thrones leaked already lol
[14:25:19] <zeeshan> no tom
[14:25:20] <zeeshan> car stuff
[14:25:39] <zeeshan> i already got replacement parts for the drawbar
[14:25:44] <zeeshan> just missing one part
[14:25:51] <zeeshan> i have enough parts for 2 rebuilds now
[14:25:51] <zeeshan> lol
[15:05:29] * JT-Shop is tired of making balls and calls it quits for the day
[15:21:59] <Cromaglious_> hmmm wonder if linuxcnc have a RT kernel for a vocore
[15:22:57] <Cromaglious_> 1" cubic linux box, w/ ethernet, wifi, and usb
[15:24:52] <pcw_home> really not worth porting to a 6 month lifetime chip
[15:30:50] <Cromaglious_> so I'm better off using it as a openwrt router
[15:34:06] <pcw_home> I think thats more its intended target
[16:07:19] <Cromaglious_> wee
[16:14:29] <Deejay> gn8
[16:20:39] <zeeshan> 4.15
[16:45:13] <SpeedEvil> It could be a handy platform if you need to fit your CNC machine in your pocket
[16:46:55] <zeeshan> that'd be one hell of a cnc
[16:46:55] <zeeshan> lol
[16:46:59] <zeeshan> machine
[16:47:59] <SpeedEvil> you know it'd sell like hot cakes on KS
[16:49:06] <XXCoder> pocket cnc
[16:49:22] <XXCoder> print out your cards to cnc machine shop bosses and interviewers
[16:49:32] <XXCoder> make sure to clean up chips!
[16:52:42] <SpeedEvil> Make one that can accurately cut little lego cast iron blocks and surface them.
[16:56:33] <XXCoder> actually I always wanted upscaled 2x2 brick
[16:56:45] <XXCoder> 2"x2" approx
[16:56:52] <XXCoder> makes for nice paperweight
[17:07:41] <zeeshan> http://i.imgur.com/Ah33Dfq.png
[17:07:45] <zeeshan> im protyping this bracket
[17:07:58] <zeeshan> any ideas what is a cheap material to make it out of
[17:08:03] <zeeshan> for verifying mounting locations
[17:08:06] <zeeshan> and swing
[17:09:23] <renesis> heh, foam board and a razor blade
[17:10:59] <renesis> you crease along the inside edge and slice in from the outside edge
[17:11:27] <renesis> and you can do gradual curves by slicing parallel on the outside surface and not cutting into the foam
[17:12:18] <renesis> http://upload.wikimedia.org/wikipedia/commons/d/d7/Yeti-USB-Microphone.jpg
[17:12:59] <renesis> that guy started as foam board, i was like wat!? when i saw the ID prototype
[17:15:17] <zeeshan> i need it sturdy enough to test the pedal
[17:15:20] <zeeshan> under 40lb
[17:17:36] <renesis> cover it in duct tape, shrug
[17:18:34] <renesis> aluminum would work but then youre like, making the bracket
[17:19:14] <renesis> you could get those nail in construction brackets
[17:20:05] <renesis> and a hammer
[17:24:53] <newtolinuxcnc> hi
[17:25:18] <XXCoder> hey new
[17:25:31] <XXCoder> zeeshan: mdf?
[17:25:38] <zeeshan> die mdf!
[17:25:42] <zeeshan> im thinking just plywood
[17:25:46] <XXCoder> its good test material
[17:25:57] <newtolinuxcnc> there is a way to connact all the limit switches to the same leg in the lpt?
[17:28:00] <newtolinuxcnc> i want to use the limit switches for homing and soft limit.
[17:28:31] <renesis> mdf is awesome for speakers and shitty for just about everything else
[17:28:49] <XXCoder> dunno I saw some nice cnc machines made from mdf
[17:28:58] <XXCoder> but yeah wouldnt use em in most cases.
[17:28:59] <renesis> how long did they last
[17:29:36] <SpeedEvil> As long as it's not overstressed, or wet, MDF lasts forever
[17:30:02] <XXCoder> SpeedEvil: wouldnt it evenually take in enough water from air
[17:30:05] <XXCoder> unless sealed
[17:30:09] <SpeedEvil> No.
[17:30:25] <SpeedEvil> Well - if your machine shop is at >80% humidity all the time
[17:32:06] <renesis> its heavy and non resonant which is great for big vibrating loads, but it crumbles, which sucks for big vibrating loads
[17:33:22] <renesis> so for something indoors that lives its life on carpet or next to electronics, mdf works, in a shop or garage id be a lot more paranoid
[17:34:04] <renesis> the machine base part not so much because inches of MDF isnt going to change much, but you cant really do that for the moving bits
[17:36:23] <Tom_itx> zeeshan, prototype it with aluminum sheet welded then make the real one from solid billet
[17:36:36] <zeeshan> im planning to make it from multiple pieces welded togethr
[17:36:37] <Tom_itx> paying close attention to grain direction
[17:36:58] <zeeshan> i was just hoping to use some sort of cheap ass plastic
[17:37:01] <zeeshan> to first make it from
[17:37:06] <Tom_itx> wood
[17:37:07] <newtolinuxcnc> there is an error input to linux cnc? i can use some leg in the LPT for that. or I have to use the limit switches input for that?
[17:37:07] <zeeshan> cant use acrylic cause the top piece will crack
[17:37:13] <zeeshan> i need to bend that top piece
[17:37:18] <zeeshan> from a straight piece
[17:38:04] <XXCoder> is there any metal crappier than alum and cheaper?
[17:38:09] <XXCoder> and easily recastable
[17:38:09] <newtolinuxcnc> i want to use the "over heating" error output from the drivers to stop the machine.
[17:38:11] <zeeshan> steel :P
[17:38:12] <zeeshan> haha
[17:38:38] <newtolinuxcnc> someone hear me?
[17:39:04] <XXCoder> I do, just not expert :)
[17:39:17] <XXCoder> read rather, hearing just notnthing I do lol
[17:39:24] <zeeshan> i dont understand your q
[17:39:37] <zeeshan> you're trying to hook up limit switches into one pin of your parallel port
[17:39:39] <zeeshan> whats the question?
[17:40:33] <Tom_itx> make the final one from Ti
[17:40:46] <Tom_itx> and swiss cheese it to lighten it
[17:41:57] <Tom_itx> the outlaw guys would go so far as to use hollow Ti bolts to save weight
[17:42:22] <newtolinuxcnc> zeeshan: yes this is one question, the other question is "there is a sperate "error" input for miscellaneous stuff. like over heating.
[17:42:29] <Tom_itx> besides... who really needs brakes anyway?
[17:42:47] <Tom_itx> newtolinuxcnc, not specifically no
[17:42:55] <pcw_home> newtolinuxcnc man motion
[17:43:28] <Tom_itx> pcw_home, i sprung for the itx version of the ASRock board to try on the mill
[17:43:52] <Tom_itx> so i'll have one of each
[17:43:52] <pcw_home> the J18/1900?
[17:43:56] <Tom_itx> 1900
[17:44:56] <zeeshan> this isnt a brake pedal
[17:44:57] <zeeshan> :-)
[17:45:22] <Tom_itx> what is it then? it looks like a clutch brake assembly
[17:45:28] <zeeshan> clutch pedal
[17:45:47] <Tom_itx> looks like both to me
[17:45:54] <newtolinuxcnc> i have physical switches, and inductive switches. the normal operation work with the inductive switches, but is something happed, and the machine hit the mecanical limit switche it will shut down the power to the machine, in this case i want to stop also the program.
[17:45:59] <newtolinuxcnc> how i can do it?
[17:46:06] <zeeshan> thats the pedal shifted forward
[17:46:11] <zeeshan> i was trying different configs
[17:46:17] <Tom_itx> oh
[17:46:22] <Tom_itx> well make up your mind..
[17:46:46] <zeeshan> i wish i had a planer
[17:46:50] <zeeshan> this would be easy to make from wood
[17:47:03] <pcw_home> newtolinuxcnc: typically the hard limits are part of the EStop chain
[17:47:10] <Cromaglious_> yeah, I have access to the vocore again
[17:48:11] <newtolinuxcnc> pcw_home: and i need to open the chain momentarily, or as long as i have problem?
[17:48:23] <Cromaglious_> TTL-232R-3V3-PCB to vocore serial pins
[17:48:39] <pcw_home> the Estop chain also includes the Big Red Switch
[17:49:11] <pcw_home> An Estop is latched
[17:49:39] <Cromaglious_> pcw_home: yours maybe... mine isn't need to replace it
[17:50:25] <newtolinuxcnc> i have 2 E stop buttons - one big for the power lines, and one small for the software.
[17:50:45] <Tom_itx> what is one without the other?
[17:51:30] <pcw_home> The button may be momentary but an Estop event is latched and requires a manual restart sequence
[17:51:34] <newtolinuxcnc> the one for the software can be a momentarily push button, or twist releas?
[17:52:46] <newtolinuxcnc> ok, i understand now.
[17:53:09] <newtolinuxcnc> you know where i can ger yellow top E-stop?
[17:53:14] <newtolinuxcnc> get*
[17:53:25] <_methods> E-bay
[17:53:34] <_methods> lol
[17:53:46] <Tom_itx> paint a red one
[17:53:53] <_methods> I-shop for E-stop on E-bay
[17:53:54] <Tom_itx> i suspect most of them will be red
[17:54:19] <newtolinuxcnc> I know, this is why i'm asking
[17:55:43] <newtolinuxcnc> now both of them are red, one small one big, but i prefer color separation
[17:56:18] <newtolinuxcnc> red for hardware (poweoff) yellow for software
[18:00:47] <newtolinuxcnc> there is and diffrance between ebay no name to ABB?
[18:03:27] <Tom_L> newtolinuxcnc, consider this: http://www.controleng.com/blogs/machine-safety/blog/e-stops-have-a-yellow-background-right/88dca635ed.html

[20:35:21] <zeeshan> fancy smancy bracket
[20:42:35] <bobo_> zeeshan: just here to bother you
[20:43:14] <zeeshan> lol
[20:43:41] <zeeshan> 16ksi stress
[20:43:44] <bobo_> where are the photos of your new machine feets ?
[20:43:44] <zeeshan> yield strength 40 ksi
[20:43:45] <zeeshan> hmmm
[20:43:54] <zeeshan> bobo they are just rtound cylinders
[20:43:57] <zeeshan> with a taper :P
[20:44:04] <zeeshan> w/ a hemisphere to swivel
[20:44:31] <bobo_> I can't see them?
[20:44:36] <zeeshan> lol
[20:47:52] <bobo_> hyd clutch -- my 06 (2006) chev truck has plastic hyd. cylinder on firewall for hyd clutch
[20:49:07] <zeeshan> http://i.imgur.com/H3DfaFc.jpg ; http://i.imgur.com/OLycM8z.jpg
[20:50:39] <bobo_> as usual GM mucked the design up. clutch petal has to be mashing floor bd. to shift .
[20:50:45] <zeeshan> lol
[20:54:03] <bobo_> those mounting feet ----- gee you do nice work , they look good . deserive a silver at-boy star for them
[20:54:32] <bobo_> thanks for the photo
[20:55:34] <zeeshan> np
[20:55:38] <zeeshan> i was happy to level the machine
[20:55:43] <zeeshan> it deserved leveling
[20:56:05] <zeeshan> http://i.imgur.com/TP6JYf9.png
[20:56:12] <zeeshan> this is structurally sound
[20:56:22] <zeeshan> but i feel like aesthetically i went a little overkill with the slots
[20:56:22] <zeeshan> lol
[20:56:36] <Tom_itx> zeeshan, here's jt's feet: http://gnipsel.com/shop/machines/machines-01.xhtml
[20:56:50] <zeeshan> ROFL
[20:56:52] <zeeshan> those are nice!
[20:57:03] <zeeshan> i love jt's structural member work
[20:57:12] <zeeshan> he does some excellent work
[20:57:22] <Tom_itx> yup
[20:58:47] <zeeshan> http://i.imgur.com/cWXx2JQ.jpg
[20:58:50] <zeeshan> thats my response image
[20:58:50] <zeeshan> :D
[20:58:56] <zeeshan> too bad its not structural
[21:00:24] <Tom_itx> did you bend em?
[21:01:04] <zeeshan> no
[21:01:08] <zeeshan> mandrel bends come like that
[21:01:11] <zeeshan> you just cut and fit them
[21:03:28] <bobo_> saw you have the parts for Microns hyd tool grip cylinder------ finaly Were the parts still warn from manufacturing ?
[21:04:17] <zeeshan> more like the smell of sitting around for 20 years :d
[21:06:38] <bobo_> good thing they are not prime source for heart/lung machines
[21:11:53] <bobo_> the hyd clutch frame-structural member ---- mayby rolled ribs . I am not sure ,but wouldn't it be only in tension ---- mounted at front ?
[21:14:43] <zeeshan> http://i.imgur.com/Usj3kc0.png
[21:14:47] <zeeshan> you can kinda see whats going on there
[21:14:52] <zeeshan> where the clutch master bolts
[21:14:58] <zeeshan> http://i.imgur.com/TP6JYf9.png
[21:15:08] <zeeshan> that gets pushed towards the firewall
[21:15:12] <zeeshan> where the clutch pedal pivots
[21:15:18] <zeeshan> sees force in the opposing direction
[21:17:54] <malcom2073> I'm gonna make a small air powered rocker engine for my first real lathe project
[21:20:57] <bobo_> zeeshan my guess is the front and also mounting is the plate having 2 horz slots . if so then it's mostly a tension force ?
[21:21:35] * zeeshan is confused on what youre asking :P
[21:22:28] <bobo_> your wanting to make it stronger ?
[21:22:33] <zeeshan> no
[21:22:37] <zeeshan> trying to make it looks better
[21:22:37] <zeeshan> :)
[21:23:07] <bobo_> nickel plate it than
[21:23:08] <zeeshan> apparently thing this weighs 2lb
[21:23:11] <zeeshan> i think thats acceptable
[21:23:18] <zeeshan> haha
[21:23:20] <zeeshan> its aluminum
[21:23:26] <zeeshan> anodize it!
[21:23:26] <zeeshan> :D
[21:26:51] <bobo_> my 1/2 ton truck uses a all plastic frame for that , and they cheaped out by also leaving off a petal return spring
[21:29:55] <zeeshan> well some cars
[21:30:02] <zeeshan> return spring is in the clutch maser
[21:31:58] <zeeshan> http://i.imgur.com/LlnWkEU.png
[21:31:59] <zeeshan> there we go
[21:31:59] <zeeshan> lol
[21:36:21] <bobo_> I am talking GM practice , you are talking give a concern manfactures
[22:12:11] <malcom2073> Hmm, there are lots people on youtube running larger steam engines, but where are they getting their steam from?
[22:12:22] <malcom2073> I mean, are they really making thier own boilers?
[22:12:24] <malcom2073> That sound scary
[22:16:16] <roycroft> they start arguments on irc and bottle the steam coming off the channel
[22:16:50] <malcom2073> oooohhhhh
[22:16:52] <malcom2073> that's smart!
[22:16:54] <roycroft> yeah
[22:16:58] <malcom2073> let's see.....
[22:17:00] <malcom2073> 3d printers!
[22:17:03] * malcom2073 opens valve
[22:17:05] <t12> zero point irc energy
[22:17:06] <roycroft> you have to get a special computer with a steam jack though
[22:17:28] <malcom2073> I have steam installed, does that count?
[22:17:28] <roycroft> emacs is better than vi
[22:17:42] <malcom2073> Ubuntu rocks, Fedora sucks
[22:17:48] <roycroft> bsd is better than linux
[22:17:58] <malcom2073> Mac > both
[22:20:55] <roycroft> pwd
[22:21:02] <roycroft> ack
[22:36:10] <zeeshan> malcom2073: boilers are dangerous only if you dont know wha tyoure doing! :P
[22:36:19] <zeeshan> to test your steam engine, juse use compressed air
[22:36:25] <zeeshan> and then spend a long time designing a boiler or buying one
[22:39:03] <zeeshan> two main equations: hoop stress = Pr/t , longitudal stress = Pr/2t <- for cylindrical designs, after you find the stresses, find the equivalent stress and compare to material yield. then fea it up to double check and account for stress concentrations
[22:39:29] <zeeshan> this also assumes thin wall
[22:40:01] <zeeshan> D/t < 10 i think -- been a while :P
