[00:00:00] <zeeshan> whats that supposed to mean! :P
[00:00:24] <MacGalempsy> that means dont graduate!
[00:01:48] <zeeshan> i just wish i could get my lathe running in a nice condition
[00:01:50] <zeeshan> and im set!
[00:04:39] <MacGalempsy> man you got that, just bust a move
[01:10:31] <archivist> zeeshan, another cause is built up edge, and when it breaks off
[01:20:06] <Tecan> http://i.imgur.com/vFCxtyb.jpg
[01:20:16] <Tecan> my 3d printing combo at the moment
[01:20:27] <Tecan> working on building a repstrap again now that i have a working printer
[01:33:29] <Oldmanbeefjerky> hi, anyone here? im not much in the loop i wanna know if any hobbyist steel workable cnc mills have been invented yet? recently on my facebook newsfeed ive been seeing allot of cafuffle about cnc's made for making guns, figured those would probably be able to mill steel
[01:33:55] <Oldmanbeefjerky> that said im definitely not planning on making guns, i live in australia, we have like 1 gun shop per state
[01:34:04] <Oldmanbeefjerky> no ammo
[01:34:04] <archivist> invented!
[01:34:44] <archivist> small hobby mills are on sale to the model engineer crowd
[01:34:44] <Oldmanbeefjerky> keeping in mind when i say for hobbyist i mean something that doesnt cost in the tens of thousands
[01:34:55] <Oldmanbeefjerky> ooh
[01:35:05] <Oldmanbeefjerky> links? models?
[01:35:22] <Oldmanbeefjerky> googlable info
[01:35:43] <archivist> where are you
[01:36:02] <Oldmanbeefjerky> australia, queensland
[01:36:17] <syyl> sieg cnc
[01:36:21] <syyl> taig cnc
[01:36:38] <syyl> $chinecrap cnc
[01:36:43] <syyl> *chinese
[01:36:48] <archivist> eg http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Milling-Machines
[01:37:20] <archivist> http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/CNC-Milling-Machines
[01:37:58] <Oldmanbeefjerky> WTF!
[01:38:04] <Oldmanbeefjerky> 198BP
[01:38:15] <syyl> yeah
[01:38:18] <syyl> pretty cheep
[01:38:22] <Oldmanbeefjerky> dayum
[01:38:34] <Oldmanbeefjerky> does the whole head component move or something
[01:38:41] <Oldmanbeefjerky> to me it looks like a drill press
[01:38:56] <archivist> I rate that as a drill
[01:39:03] <syyl> thats how milling machines look
[01:39:08] <syyl> not like a flatbed printer.
[01:39:50] <archivist> xy table is another 108
[01:39:51] <syyl> if you rip the housing of a big vmc
[01:39:58] <syyl> it looks also like a big drillpress
[01:40:27] <archivist> its small 20kg
[01:40:48] <Oldmanbeefjerky> no ive seen a mill like that in person, the bed had motors on it
[01:41:04] <Oldmanbeefjerky> is what i was getting at
[01:41:20] <archivist> a cnc one?
[01:41:34] <Oldmanbeefjerky> it looked like the seig only way bigger
[01:41:49] <archivist> http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/CNC-Milling-Machines/Sieg-KX1-CNC-Hobby-Mill
[01:42:28] <archivist> that just has safety casing covering a basic machine
[01:42:42] <archivist> with the motors too
[01:43:29] <archivist> but I would not get that as it uses an expensive driver board USB and mach3
[01:43:53] <archivist> there are cheaper conversions where you can use linuxcnc
[01:44:52] <Oldmanbeefjerky> ooh that wasnt a controlled cnc
[01:45:00] <Oldmanbeefjerky> just got that
[01:45:30] <Oldmanbeefjerky> sorry if im loose with the term cnc
[01:46:02] <archivist> valen who often is in here is in au too and may know local distributors
[01:47:25] <Oldmanbeefjerky> just realzing that those are not computer controlled
[01:47:26] <Oldmanbeefjerky> lol
[01:47:46] <archivist> some are I have pointed at
[01:48:51] <Oldmanbeefjerky> damn $3kbp
[01:48:53] <archivist> at the cheaper end many convert manual to cnc themselves too
[01:49:11] <Oldmanbeefjerky> thats what i was about to ask
[01:49:57] <Oldmanbeefjerky> what would you say the cost would be of stepper motors and the controller board?
[01:49:59] <renesis> taig can do steel but you gotta go shallow and get feeds and speeds dialed in or it screams
[01:50:11] <renesis> like, youre going to want hearing protection on
[01:50:28] <Oldmanbeefjerky> i dont mind having to do everything slowly
[01:50:41] <syyl> i hear that all the time
[01:50:50] <syyl> you get sick of it in about a week
[01:50:51] <Oldmanbeefjerky> well, with steel anyway
[01:50:55] <renesis> yeah seriously
[01:51:01] <Oldmanbeefjerky> hmm
[01:51:05] <syyl> "i dont mind speed and precision"
[01:51:11] <renesis> taig will fly through aluminum no issue
[01:51:14] <Oldmanbeefjerky> well precision is a must
[01:51:24] <syyl> and then they day comes where you just want something finished _now_
[01:51:35] <Oldmanbeefjerky> i only need to do steel for mechanical parts
[01:51:41] <archivist> for really cheap st** there is also http://www.sherline.com.au/
[01:52:10] <renesis> im def on on the taig side of the taig vs sherline debate
[01:52:19] <renesis> enough issue fitting in my envelope as is
[01:52:32] <syyl> the taig looks like a machine
[01:52:32] <Oldmanbeefjerky> hey, given i have next to no knowledge on the matter, how would i go about making gears?
[01:52:39] <archivist> http://taig.com.au/webstore/
[01:52:44] <syyl> the sherline is always a bit toy-like
[01:52:48] <Oldmanbeefjerky> taig is in aus, i like that
[01:52:49] <renesis> ikr
[01:53:16] <Oldmanbeefjerky> one of the biggest issues i face in any project i try to start is gearing
[01:53:28] <Oldmanbeefjerky> making gearboxes and finding gears
[01:53:30] <archivist> Oldmanbeefjerky, OK I am a gear maker, now you need a rotary of some quality
[01:53:34] <Oldmanbeefjerky> of which i have never managed
[01:53:58] <Oldmanbeefjerky> rotary as in lathe? or some style of the affirmentioned mill?
[01:54:02] <archivist> I made my mill to make gears
[01:54:17] <archivist> a 4th axis on the mill
[01:54:23] <Oldmanbeefjerky> my goal is to make a 2-3 speed gearbox some day, sized for rc cars
[01:54:57] <syyl> https://dl.dropboxusercontent.com/u/24396704/Deckel%20G2/2011-12-05_21-04-40_323.jpg
[01:55:00] <archivist> you can just buy in gears and fit to shafts, you need a lathe
[01:55:00] <syyl> rotary axis
[01:55:05] <renesis> could just buy sprockets and shafts off the shelf and machine cases
[01:55:18] <renesis> sherline rotary table looks pretty cool
[01:55:37] * archivist would not get the sherline rotary
[01:55:50] <renesis> why not
[01:55:57] <archivist> vertex rotary HV4 is ok
[01:56:08] <renesis> is it more $$$?
[01:56:18] <archivist> similar or less
[01:56:26] <renesis> neat
[01:56:45] <Oldmanbeefjerky> i see
[01:56:57] <archivist> Vertex has a real specification for rotary accuracy that none of the others have
[01:57:00] <renesis> archivist: does it come nema ready?
[01:57:10] <Oldmanbeefjerky> i find gears to be quite costly and also selection is limited
[01:57:16] <archivist> no you need an adapter tube
[01:57:36] <Oldmanbeefjerky> anywho, what should i do> get a taig for around $1.1k and so up my own control system, or buy a complete package
[01:57:46] <syyl> then you will find cnc, a rotary axis and gearcutters way more costly
[01:57:48] <syyl> :)
[01:57:50] <archivist> Oldmanbeefjerky, there are a few online sellers of low cost gears
[01:58:09] <archivist> HPC is one
[01:58:15] <syyl> the price of a good gear cutter set will make you cry
[01:58:40] <archivist> a hobbing machine is the holy grail
[01:58:42] <Oldmanbeefjerky> if i really had to could i just normal mill?
[01:59:03] <archivist> you need to rotate accurately the blank
[01:59:13] <syyl> of course
[01:59:24] <syyl> gears where made on manual machines all the time
[01:59:50] <Oldmanbeefjerky> because now that i think about it i probably wont need to make that many gears
[02:00:27] <archivist> only linuxcnc (as far as I know) can cnc a hobbing machine at low cost http://www.collection.archivist.info/searchv13.php?searchstr=barber+colman
[02:01:15] <archivist> how many gears do you want :)
[02:01:50] <Oldmanbeefjerky> so about my other question, what should i do? get a completed package or buy a thousand dollar taig just without the controller, and possibly steppers either
[02:01:59] <archivist> and how small http://gears.archivist.info/gears/IMG_1214_th.JPG
[02:02:04] <Oldmanbeefjerky> then do myself
[02:02:56] <archivist> cutters can be £60 plus and many dont make cutters in the sizes you may want
[02:03:42] <archivist> if you want helical gears then it is another can of worms
[02:03:56] <Oldmanbeefjerky> well for me cutters is no longer an issue
[02:04:22] <Oldmanbeefjerky> so about the taig setup
[02:04:33] <archivist> you have a stack?
[02:05:01] <archivist> down to what module
[02:05:13] <archivist> or DP
[02:05:31] <syyl> everytime i would have to cut gears
[02:05:48] <syyl> first I shop the retailers for an availible gear
[02:06:00] <syyl> then I look trough my module cutters
[02:06:01] <syyl> curse
[02:06:06] <syyl> and change my design ;)
[02:06:27] <Oldmanbeefjerky> from what i am taking in, they are charging $1k for the control system and steppers
[02:06:41] <Oldmanbeefjerky> and selling a setup without it but ready
[02:06:50] <archivist> my local gear stockist http://www.hpcgears.com/
[02:07:02] <syyl> hr, youre lucky
[02:07:04] <syyl> :)
[02:07:25] <Oldmanbeefjerky> oh dang i was looking at the usa site
[02:07:45] <syyl> keep in mind that you want ball screws for the cnc
[02:08:00] <syyl> its not just a matter of nailing motors to a manual milling machine
[02:08:26] <archivist> you dont need ball screws IF you write unidirectional g code
[02:08:42] <syyl> ok yes
[02:08:53] <syyl> but then you dont have the possibility to climb cut
[02:09:16] <archivist> all my gear cutting code is unidirectional except for the bevel generator
[02:10:00] <archivist> climb on a taig....
[02:11:32] <Oldmanbeefjerky> aww man, in australia a cnc ready stepper/controllerless setup costs $2k
[02:11:34] <archivist> german gear stockist http://info.maedler.de/
[02:11:50] <syyl> thats the go-to gear guy here
[02:11:52] <archivist> but your $ is 50p
[02:12:47] <archivist> I see the low value au $ when I get a donation for a manual scan
[02:14:09] <archivist> syyl, I got some deckel manuals the other day DC 30 and 40
[02:14:27] <syyl> d30?
[02:14:34] <syyl> thats one of the bigger machining centres?
[02:14:39] <archivist> yes
[02:14:42] <syyl> or machine cell
[02:14:58] <syyl> cool :D
[02:15:08] <syyl> dont see those very often
[02:15:16] <archivist> yup, and the covers were black, so was well used or not so reliable
[02:15:33] <syyl> :D
[02:15:44] <syyl> i just got my "50 years of friedrich deckel" book
[02:15:54] <syyl> found it on ebay for 3 bucks
[02:16:08] <syyl> the antique online shop wantet 50orso
[02:16:22] <archivist> I got a pile of used machine manuals £22
[02:16:35] <syyl> collecting? :)
[02:16:52] <archivist> fleabay where crap descriptions help me
[02:17:43] <archivist> syyl, sort of manual archive http://www.collection.archivist.info/searchv13.php?searchstr=deckel
[02:17:43] <Oldmanbeefjerky> well it seems tiag australia isnt the same business
[02:17:56] <Oldmanbeefjerky> morelike a proxy run by someone else
[02:18:02] <archivist> local distribution
[02:18:08] <syyl> oh wow
[02:18:14] <Oldmanbeefjerky> they do a 500% markup
[02:18:47] <Oldmanbeefjerky> even if it takes longer ill find a way to buy from USA
[02:19:10] <Oldmanbeefjerky> hey, if im buying a used mill, what would i need to look out for?
[02:19:24] <Deejay> moin
[02:19:29] <archivist> Oldmanbeefjerky, it can be cheaper to convert a better second hand machine you find locally
[02:19:35] <syyl> look out not to buy an old worn out bridgeport ;)
[02:20:37] <Oldmanbeefjerky> given im still looking at ultimately spending less than $2k
[02:21:05] <Oldmanbeefjerky> to reach 100% complete
[02:21:29] <archivist> mine was less but it is home brew from other machine parts
[02:22:15] <archivist> some scrounging and free stuff is in my build
[02:22:27] <Oldmanbeefjerky> ?
[02:23:52] <archivist> eg first cuts some axes no cnc left manual http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_03_cnc/P2030017.JPG
[02:24:18] <archivist> a two axis gear cutter
[02:25:04] <archivist> 3 axis Z still manual http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_18_cnc/P2180014.JPG
[02:27:42] <Oldmanbeefjerky> i see
[02:27:51] <Oldmanbeefjerky> very homebrew indeed
[02:28:11] <bobo_> archivist : realy like what you have done with your living room .
[02:38:29] <archivist> Oldmanbeefjerky, the base is of a Citizen tool setting microscope, the column is a lathe bed
[02:39:00] <archivist> bobo_, old free and single, one can :)
[02:39:49] <Oldmanbeefjerky> mmhmm
[02:41:16] <archivist> Oldmanbeefjerky, the early version was not hight enough and was too flexible so got jacked http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_07_10_cnc_with_LCD_P4/IMG_0267.JPG
[02:41:47] <archivist> better focus http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_07_10_cnc_with_LCD_P4/IMG_0268.JPG
[02:45:20] <bobo_> archivist : here in america -- land of the free , have been told , as in we don't approve , I can't do those type of thing's . inside my home
[02:46:12] <Oldmanbeefjerky> so many steppers
[02:47:06] <archivist> 5 axis for helical gear milling
[02:47:13] <Oldmanbeefjerky> hey so what do you think it would set me back to convert or replace a busted electrics/controller of a hobby sized cnc i find?
[02:47:32] <Oldmanbeefjerky> so basically steppers and controllers what are they worth
[02:48:31] <archivist> depends what is broken, often a used stepper machine can have working drivers and motors, so my lathe cost about a £5 to get working
[02:48:57] <archivist> and another 5 when a stepper driver chip died
[02:49:22] <archivist> old free pc and monitor
[02:50:02] <archivist> works off the parallel port, home brew port to stepper driver interface
[02:50:19] <Oldmanbeefjerky> ooh
[02:50:46] <archivist> you can get a fleabay breakout board for less than £30
[02:51:26] <archivist> I am referring to my Starturn http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_09_10_Starturn_cnc_lathe/P1010036.JPG
[02:51:51] <MrSunshine> http://www.woodcraft.com/Images/products/400/127282.jpg anyone know if with these types of bit in a cnc it would be possible to cut sharp inside corners or would they look very strange? =)
[02:54:02] <Oldmanbeefjerky> oh wait i just realized
[02:54:05] <Oldmanbeefjerky> i have a reprap
[02:54:15] <archivist> repcrap
[02:54:24] <Oldmanbeefjerky> i can literally just reprogram the board
[02:55:25] <Oldmanbeefjerky> thats controller down
[02:56:22] <archivist> remember reprap stuff is not designed to drive larger motors
[03:10:56] <archivist> Oldmanbeefjerky, another commodity gear supplier http://www.sdp-si.com/
[03:13:17] <archivist> http://www.rpmechatronics.co.uk/shop/index.php?cPath=32
[03:14:46] <archivist> who are over there too http://www.relianceprecision.com.au/
[03:18:04] <Oldmanbeefjerky> yeah i know, but asuming the pole setup is the same, its not exactly hard to boost it up
[03:18:15] <Oldmanbeefjerky> stepper H bridge or somesuch
[03:21:16] <archivist> well proper current control at higher levels is not just boosted
[03:23:50] <archivist> you may need 50+ volts and a number of amps for a larger stepper to get it to any speed
[03:24:03] <Oldmanbeefjerky> yes, thats hat i meant
[03:24:51] <archivist> like this hobbing setup I was testing http://www.collection.archivist.info/archive/mirror/JS/IMG_1731.JPG also uses a cheap breakout board
[03:34:45] <Oldmanbeefjerky> i wont care so long as i can get the job done
[03:38:02] <Oldmanbeefjerky> looks like ill be keeping an eye out for taig mills already in aus
[03:40:19] <Cromaglious> now I really have to find a plasma cutter and build a plasma table..
[03:41:01] <Cromaglious> plasma table is almost easier than a cnc mill or router table..
[03:41:38] <archivist> Oldmanbeefjerky, the smaller mills can leave a poor finish
[03:42:03] <Oldmanbeefjerky> how so?
[03:42:06] <archivist> the reason is flexible column
[03:42:11] <Oldmanbeefjerky> ah
[03:42:17] <Oldmanbeefjerky> is this purely asthetic?
[03:42:21] <archivist> why I boxed mine up
[03:42:23] <Oldmanbeefjerky> superficial*
[03:42:52] <archivist> vibration and real bending under cutting load
[03:43:09] <Oldmanbeefjerky> oh
[03:43:51] <archivist> I still want to make mine better
[03:44:08] <Oldmanbeefjerky> the colum is just a pipe isnt it?
[03:44:42] <archivist> rectangular tube
[03:44:55] <archivist> ish depends on what make
[03:46:18] <Cromaglious> filling the colum with concrete always helps...
[03:46:43] <Oldmanbeefjerky> this is an issue that requires you do slow down the cutting isnt it
[03:47:25] <archivist> if you slow too much and have too light a cut, you start rubbing
[03:48:29] <archivist> if rubbing then the machine is bending out the way
[03:49:56] <archivist> it is educational to have a dti on the table set it to 0 resting on the head, lean on the column see how far it moves
[03:50:40] <Oldmanbeefjerky> dti?
[03:50:54] <archivist> dial test indicator
[03:51:00] <Oldmanbeefjerky> oh
[03:51:45] <archivist> mine was moving about 5 thou before the stiffening
[03:52:22] <Oldmanbeefjerky> ah right i see
[03:52:24] <Oldmanbeefjerky> damn
[03:53:52] <archivist> some of the cheap mills are U section columns probably
[03:54:48] <Oldmanbeefjerky> in any case it seems i dont have enough money to outright buy a working mill
[03:55:25] <Oldmanbeefjerky> and trying to fix one within price range comes at the risk of it not being any good even when it works
[03:58:45] <archivist> any scrap yards near?
[03:59:10] <Oldmanbeefjerky> one, but its off limits, it has a recycling shop tho
[03:59:45] <archivist> ask in there also look at local factory auctions
[03:59:50] <archivist> http://www.ebay.co.uk/itm/Boxford-190VMC-Milling-Machine-CNC-As-Photos-/151585974280
[04:00:16] <archivist> one local Boxford went for £300
[04:00:53] <Oldmanbeefjerky> its all super heavy mining stuff here, mills dont get sold, they get scrapped when the business changes over
[04:00:54] <archivist> I put linuxcnc on it for the owner
[04:02:10] <Oldmanbeefjerky> what im getting at is every business with a mill uses massive mills
[04:02:45] <Oldmanbeefjerky> in my area
[04:03:16] <archivist> education is where those little boxfords are being chucked out of
[04:06:38] <archivist> and got a lathe yet?
[04:32:51] <Oldmanbeefjerky> nope
[04:32:57] <Oldmanbeefjerky> lathe wont come until way way later
[04:33:15] <Oldmanbeefjerky> like if i ever make a business of engineering, then maybe
[04:34:39] <archivist> er gears are round as are shafts, rather hard to make gears and boxes without
[04:36:22] <archivist> I actually use a manual lathe the most
[04:39:52] <archivist> also used to make arbors to hold cutters and gears on the mill
[04:40:18] <XXCoder> man
[04:40:25] <XXCoder> job is getting pretty good
[04:40:38] <XXCoder> starting to get hang of it
[04:40:50] <XXCoder> and starting to get used to 10 hr/4 days shifts lol
[04:53:19] <Swapper> what do you work with ?
[04:56:46] <XXCoder> cnc machine
[04:56:54] <Swapper> ook
[04:57:01] <XXCoder> oh
[04:57:12] <XXCoder> airplane parts, some disc part
[04:57:17] <XXCoder> says its engine mount something
[04:57:23] <XXCoder> 2 in wide I guess
[04:57:29] <Swapper> ok cool
[04:57:35] <XXCoder> then I started setup but not complete on other one
[04:57:41] <XXCoder> ball joist thingy
[04:57:48] <XXCoder> not ball inside but surrounding part
[04:57:54] <Swapper> what machine ?
[04:58:09] <XXCoder> heh ancient fadal 1988
[04:58:28] <Swapper> ok
[04:58:43] <archivist> new boy gets an old machine
[04:58:50] <XXCoder> yup
[04:59:05] <XXCoder> my first cnc machine at other place was pmx something
[04:59:12] <XXCoder> newer than that fadal lol
[04:59:14] <Swapper> David deCaussin have som vids on a version of the Fadals on youtube
[04:59:17] <Swapper> real nice machines
[04:59:26] <XXCoder> but oldest cnc in whole place other place
[04:59:48] <XXCoder> yeah they has nicer but generally older machines
[05:00:03] <XXCoder> other place I interned at has mostly newer but well hurco
[05:00:13] <XXCoder> hurco is nice but apparently bottom
[05:00:15] <XXCoder> line
[06:43:28] <Tom_itx> pi 2 is out
[06:44:38] <SpeedEvil> err - what?
[06:44:48] <SpeedEvil> Also, the Gulf war is over.
[06:45:03] <SpeedEvil> And Standard Oil got broken up
[06:46:18] <Tom_itx> apparently it's old news?
[06:46:22] <Tom_itx> just got an email...
[06:46:37] <SpeedEvil> It's been a couple of weeks, I guess.
[06:46:41] <SpeedEvil> It's a retarded upgrade.
[06:47:01] <SpeedEvil> They simply boosted the CPU and RAM, and lefft the IO alone
[06:47:31] <Tom_itx> i didn't have one in my plans anyway
[06:47:42] <SpeedEvil> So, all four USB ports, and the 100mbit network - are all connected through a power-hungry network-hub chip to one solitary USB port
[06:50:22] <CaptHindsight> the pi isn't about IO it's about getting dev platforms into the hands of starving children so that they can learn to code
[06:51:25] <CaptHindsight> does anyone actually expect them to learn how to code on old pc's?
[06:52:25] <Tom_itx> yes
[06:52:47] <Tom_itx> boot it with cpm
[07:00:15] <CaptHindsight> http://www.raspberrypi.org/blog/archive/ look at what they have accomplished, sold >5m units, piano stairs, games, lots of birthdays, and just recently an illuminated pedalboard!
[07:03:04] * SpeedEvil sighs.
[07:03:17] <SpeedEvil> It could have been an awesome platform, and they're going full retard.
[07:03:34] <MrSunshine> hahahahaha
[07:03:47] <SpeedEvil> Sorry, that was unkind.
[07:03:53] <SpeedEvil> Arduino are the ones doing that.
[07:08:06] <CaptHindsight> http://www.extremetech.com/computing/148482-the-true-cost-of-a-raspberry-pi-is-more-than-you-think
[07:09:25] <CaptHindsight> if they gave kids smartphones they could teach them to code and track them at the same time
[07:10:02] <CaptHindsight> or even a low cost tablet with keyboard http://www.walmart.com/ip/Visual-Land-Prestige-Elite-9-Tablet-8GB-Quad-Core-Keyboard-Case/41008103
[07:10:42] <SpeedEvil> yeah
[07:11:03] <SpeedEvil> The low power argument completely goes away versus a second hand laptop
[07:11:14] <SpeedEvil> as practically any dispaly you use will use more
[07:16:41] <CaptHindsight> the Rpi proved that low cost is more important to most than open source and details like power supplies, cables the display, how do you transport it etc are issues that are far too complex to comprehend and analyze
[07:17:19] <SpeedEvil> And the Pi killed many other boards
[07:18:04] <SpeedEvil> If one platform has 5 million users, and is terrible - you're basically going to face a really, really hard challenge to sell boards - even at the same price - if you are starting out.
[07:20:38] <CaptHindsight> like the bananna pi and others with the same pinouts and form factors with better SOC's
[07:21:01] <SpeedEvil> The other more subtle issue is that it's killed all 'western' makers
[07:21:19] <CaptHindsight> sounds like broadcon
[07:21:53] <SpeedEvil> While in principle you can do a banana pi, if you live in china, have good access to the chinese supply chain, and already have a well-capitalised plant - you're not going to be doing the same in the west.
[07:22:39] <SpeedEvil> (for $35)
[07:22:39] <CaptHindsight> they have a program/philosophy called Beachhead, they have been doing this for years with cable modems, routers,switches for years
[07:23:50] <SpeedEvil> And yes - the 'coincidence' that a high-up broadcom exec happens to pick broadcom chips over and over doesn't help
[07:24:11] <SpeedEvil> (who is the founder of the PI foundation)
[07:33:54] <malcom2073> Lol starving kids learning to code.
[07:40:16] <CaptHindsight> malcom2073: the plan might go like this: get Rpi into kids hands, they learn to code and write the next killer app for the http://www.engadget.com/2015/03/03/pebble-time-is-most-funded-kickstarter/ , overthrow the current warlord and end the genocide
[07:40:31] <malcom2073> It might, yes
[09:01:39] <CaptHindsight> http://www.onlinemetals.com/merchant.cfm?pid=7852&step=4&showunits=inches&id=322&top_cat=0 yikes, maybe as a last resort and you need it tomorrow
[09:04:26] <_methods> http://www.bigmessowires.com/2015/03/05/lisa-native-floppy-emulation/
[09:23:43] <SpeedEvil> CaptHindsight: At that price, it's probably easier to get some white paint, remove the TiO, and process it yourself
[09:23:50] <SpeedEvil> ceaper
[09:40:59] <ssi> morn
[09:41:50] <_methods> https://www.youtube.com/watch?v=VTzKIs19eZE
[09:42:06] <_methods> super tiny furnace hehe
[09:42:24] <ssi> neat
[09:48:00] <ssi> _methods: I kinda want to do this!
[09:48:04] <_methods> yeah
[09:48:10] <_methods> hehe ordering carbon rod now
[09:48:20] <ssi> not gonna scavenge from batteries like he did?
[09:48:31] <_methods> good luck finding those batteries
[09:48:36] <ssi> walmart? :P
[09:48:42] <dirty_d> tahts pretty cool, lol
[09:48:48] <dirty_d> you can get those batteries anywhere
[09:48:49] <_methods> last ones i got had regular c cells in it
[09:48:54] <ssi> lame :(
[09:48:58] <dirty_d> use D cells
[09:48:58] <_methods> yeah
[09:49:30] <dirty_d> i melted stuff with those carbon electrodes and a car battery when i was a kid, lol
[09:49:31] <ssi> where are you getting the rod, and how much is it?
[09:49:41] <_methods> i'm checking mcmaster now
[09:49:49] <_methods> should be able to get regular carbon rods
[09:50:31] <ssi> "The alkaline one is not what's needed, the cheap zinc chloride one is needed. Alkaline don't have carbon rods"
[09:50:33] <_methods> carbon gouge rods
[09:50:36] <dirty_d> metal fume fever, i got that once
[09:50:47] <_methods> yeah that zinc sux
[09:50:52] <dirty_d> welding galvanized tubing
[09:50:56] <ssi> yeah I've had it
[09:51:01] <ssi> drink milk, you'll be fine :)
[09:51:05] <_methods> i'll just grab some gouge rods from work
[09:51:13] <ssi> http://www.apexbattery.com/6-volt-lantern-battery-heavy-duty-zinc-chlor.html?utm_source=googlepepla&utm_medium=adwords&id=56128534817&gclid=CMym2eWFlMQCFcxj7Aoda2YAmg
[09:51:28] <dirty_d> it doesnt have to be the 6V kind
[09:51:31] <dirty_d> any dry cell will work
[09:51:48] <dirty_d> you can but carbon arc rods meant for that purpose anyway
[09:51:56] <ssi> http://www.amazon.com/Eveready-Volt-Lantern-Battery-1209/dp/B0043CHX38/ref=sr_1_4?ie=UTF8&qid=1425655853&sr=8-4&keywords=lantern+battery+zinc
[09:51:57] <_methods> http://www.mcmaster.com/#7979a15/=w6xi85
[09:52:02] <_methods> 10 pack for $6
[09:52:10] <ssi> not bad
[09:52:22] <dirty_d> ive never gotten to actually use one of those i dont think
[09:52:32] <_methods> arc gouge
[09:52:45] <ssi> http://www.mcmaster.com/#welding-cable/=w6xilr
[09:52:46] <dirty_d> i think we had them though, the holder connects to an air compressor and blows air through it
[09:52:48] <ssi> instead of buying THHN from home depot
[09:52:52] <ssi> welding cable would be much better
[09:52:59] <_methods> yeah
[09:53:19] <dirty_d> maybe you can find heavy guage jumper cables for cheaper
[09:53:20] <_methods> probably cut a gouge rod in half and use for quite awhiel
[09:53:25] <_methods> awhile
[09:53:27] <ssi> although I can probably jsut use my existing arc welder cables
[09:53:53] <_methods> oh snap listen to this bit of dirtiness
[09:53:57] <_methods> http://www.theverge.com/2015/3/6/8161251/utorrents-secret-bitcoin-miner-adware-malware
[09:54:31] <ssi> lol I knew things like that were gonna start popping up
[09:57:07] <_methods> now i gotta find some refractory bricks
[09:57:25] <_methods> oh shit haha one of our big customers is right next door and they draw wire
[09:57:40] <ssi> mcmaster sells refractory bricks
[09:57:42] <_methods> and just happen to line their furnaces with..............
[09:57:47] <ssi> hah nice
[09:57:56] <_methods> yeah i'm gonna go over there and beg for some bricks
[09:59:11] <_methods> i got an old harbor freight stick welder i guess i should be able to use
[09:59:24] <_methods> i knew i'd find a use for that thing one day lol
[09:59:35] <ssi> perfect :D
[09:59:37] <_methods> it's actually a hobart stick welder
[10:00:31] <ssi> walmart does still sell zinc carbon batteries it looks like
[10:00:47] <_methods> someone told me those things were full of double a's
[10:00:57] <ssi> the alkaline ones probably are
[10:01:04] <_methods> so i went and bought one and it was full of regular c's
[10:01:07] <ssi> but the non-alkaline ones are likely zinc carbon
[10:01:07] <_methods> yeah
[10:01:42] <jdh> ethernet/ip is the worst name ever
[10:01:45] <ssi> http://www.houseofbatteries.com/documents/926.pdf
[10:01:49] <ssi> http://www.walmart.com/ip/Rayovac-RAYOVAC-926-Lantern-Battery-Industrial-12V-Screw-Term/40725314
[10:08:19] <_methods> heh carbon electrodes......check
[10:08:28] <_methods> now for some refractory brick
[10:08:46] <_methods> increase insurance fire policy
[10:08:56] <ssi> first things first!
[10:09:00] <_methods> heheh
[10:32:21] <HoloPed> hi all
[10:32:40] <HoloPed> Has anyone built a laser cutter ? in the 60W range, CO2 laser
[10:32:56] <_methods> plasma rifle in the 40w range
[10:33:09] <_methods> uzi 9mm
[10:33:21] <_methods> hehe
[10:33:33] <_methods> yep there are people in here that have built what you speak of
[10:33:53] <SpeedEvil> HoloPed: Define built.
[10:34:06] <SpeedEvil> Do you mean starting from glass tubes, and a bottle of CO2?
[10:34:16] <SpeedEvil> In which case, not yet
[10:34:38] <_methods> i saw some thing on hackaday.io where someone was building their own tube lol
[10:34:46] <HSD> Heh just read that yesterday
[10:35:12] <HSD> I want to build one, but buy the tube and lenses. So perhaps assemble is a better word?
[10:35:13] <HSD> :)
[10:35:15] <_methods> not sure if they ever got it working
[10:35:19] <HoloPed> SpeedEvil, started with a CO2 laser on ebay and built the rest - Frame, linear motions, etc
[10:35:32] <HSD> How much did it end up costing?
[10:35:41] <HoloPed> like this
[10:35:42] <HoloPed> http://openbuilds.com/threads/v-slot-co2-laser-60-100w.617/
[10:36:17] <SpeedEvil> You can do silly laser cutter very easilyt
[10:36:26] <SpeedEvil> If you don't bother with the beam folding
[10:36:38] <SpeedEvil> and just either move the workpieve under a static tube, or move the tube
[10:37:23] <SpeedEvil> This does of course make making it into a compact machine basically impossible - but do you care if it's 6 foot, not 2 feet tall - if you're not moving it
[10:38:45] <HoloPed> SpeedEvil, what is a workpieve ?
[10:38:52] <HoloPed> aren't the tubes water cooled ?
[10:38:54] <SpeedEvil> workpiece
[10:38:56] <SpeedEvil> I can't spell
[10:38:59] <SpeedEvil> yes
[10:39:00] <HoloPed> right
[10:39:04] <SpeedEvil> Well - type
[10:39:12] <SpeedEvil> I don't think workpiece is spelled with a v.
[10:39:27] <HoloPed> so moving the tube instead of a set or mirrors, thats the idea ?
[10:39:35] <HoloPed> and mounting the tube vertically ?
[10:39:36] <SpeedEvil> And yes, they are water-cooled.
[10:39:41] <SpeedEvil> Basically.
[10:39:50] <SpeedEvil> Moving the work is probably simpler.
[10:40:04] <HoloPed> depends on size, but yeah
[10:40:04] <HoloPed> I'
[10:40:17] <HoloPed> I've built a 3D printer, I'm not worried about the complexity of mirrors
[10:40:46] <SpeedEvil> I'm not saying that doing a folded optics is impossible - just that you now have to take into account various sorts of astigmatism, and tget the beam absolutely collimated right - over a variable path length
[10:40:49] <HoloPed> but I guess its one more thing that needs maintanence
[10:41:12] <HoloPed> I see what you mean
[10:41:15] <SpeedEvil> Yeah - it's at the very least worth considering if you actually want to bother with a folded path.
[10:42:54] <_methods> heh this guy made it all
[10:42:58] <_methods> http://www.jarrodkinsey.org/co2laser/co2laser.html
[10:43:01] <HoloPed> do you know of any stationary tube builds ?
[10:43:03] <_methods> pretty nuts
[10:43:32] <_methods> he is using polished pennies for mirrors
[10:43:47] <archivist> ask ssi about failure modes too
[10:43:51] <SpeedEvil> _methods: yeah - I saw that
[10:43:53] <_methods> lol
[10:43:55] <SpeedEvil> HoloPed: nope
[10:44:06] <dirty_d> hrrrm, i wanna make some kinda parametric cam program
[10:44:08] <SpeedEvil> HoloPed: I haven't properly invetigated
[10:44:20] <dirty_d> except done by programming
[10:44:53] <dirty_d> seem like a good idea?
[10:45:21] <dirty_d> ive got solidspace exporting all the entities for a part
[10:45:41] <SpeedEvil> dirty_d: solidworks?
[10:45:47] <dirty_d> so you could graphically select circles and lines and centerpoints and stuff
[10:45:57] <SpeedEvil> I mean openscad
[10:46:16] <dirty_d> doesnt that not really work well?
[10:47:09] <SpeedEvil> dunno
[10:48:24] <dirty_d> i think im thinking of something else, that looks pretty cool
[10:50:24] <dirty_d> doesnt look like it does any toolpath stuff though
[10:58:14] <CaptHindsight> https://www.parallella.org/board/ or Z-turn Board http://www.myirtech.com/list.asp?id=502 does anyone know if they need any blobs to run or boot?
[10:58:20] <CaptHindsight> PCW: ^^
[10:59:48] <pcw_home> I doubt that either need any blobs (video might but those platforms are better without video)
[11:00:45] <pcw_home> if you dont need a lot of FP the Z-turn is nice since it has 96 I/O
[11:00:58] <pcw_home> (no idea what voltage though)
[11:01:07] <CaptHindsight> I was looking over the list of boards or ddevices that don't require blobs and they weren't listed
[11:01:21] <CaptHindsight> yes, looks great
[11:03:28] <_methods> For example, Foulkes tells us that “Ive explains how the molecules in Apple gold are closer together, making it twice as hard as standard gold.”
[11:03:32] <_methods> apple lol
[11:03:42] <_methods> their gold has closer atoms they are so cool
[11:06:24] <CaptHindsight> rather than agreeing with _methods undeniable facts and clarifying their statement, _methods was burned at the stake as a heretic and for "talkin like a fag" :)
[11:06:28] <archivist> hehe hard alloy/soft(pure) gold
[11:06:59] <_methods> heheh
[11:06:59] <_methods> sorry
[11:07:01] <_methods> http://howtospendit.ft.com/technology/77791-the-man-behind-the-apple-watch
[11:07:04] <_methods> there we go
[11:07:17] <_methods> jony ive interview
[11:07:31] <_methods> apple is so grand they've even made gold better
[11:08:01] <CaptHindsight> I didn't even know my gold needed bettering. Thanks Apple!
[11:08:20] <CaptHindsight> please tell me what else I should buy
[11:09:22] <CaptHindsight> "Nothing escapes this forensic level of thinking." :)
[11:09:37] <_methods> heheh
[11:10:20] <_methods> never ceases to amaze me how putting an inferior product in an inferior box will net you colossal profits
[11:10:29] <_methods> in a superior box
[11:10:30] <_methods> sorry
[11:10:50] <CaptHindsight> "not for the rational"
[11:10:50] <_methods> just make the package pretty and everyone will buy it
[11:11:30] <archivist> charge more and they think it is better
[11:11:34] <_methods> indeed
[11:12:31] <CaptHindsight> I've had customers ask for that for industrial items. They wanted the printer shipped to customers in a box, in a box in a box like their iphone was
[11:12:52] <CaptHindsight> black, with velvet lining
[11:13:19] <CaptHindsight> so that the unboxing would be an experience
[11:13:55] <_methods> fit, form, function
[11:14:09] <_methods> all i need
[11:15:11] <_methods> if it comes in a pretty package i can appreciate that but it won't be part of my purchasing decision
[11:15:52] <_methods> i have an ugly tablesaw in my garage that is about 100 years old and still running strong
[11:16:14] <_methods> i'm pretty sure apple will never be able to say that about any of their products
[11:17:16] <HSD> Hahaha. unfortunately they don't care. Everyone dumps their products each year and buys new ones.
[11:17:36] <HSD> mostly because fruitco tells them to
[11:18:26] <CaptHindsight> what a good consumer should be doing
[11:18:31] <HSD> haha.
[11:18:39] <HSD> it's all about marketing isn't it?
[11:18:57] <CaptHindsight> and keeping people dumb and insecure
[11:19:15] <archivist> making you NEED to upgrade
[11:19:19] <CaptHindsight> http://www.3ders.org/articles/20150305-nanosteel-expands-material-portfolio-for-metal-3d-printing.html
[11:19:32] <CaptHindsight> "the company was able to build a crack-free, fully dense bulk sample with hardness levels >1000 HV."
[11:19:42] <_methods> but can they make apple gold
[11:19:48] <CaptHindsight> lol
[11:20:42] <archivist> is that snake oil grade hardness
[11:20:45] <CaptHindsight> anyone heard from Pete after yesterdays ice and snow storms?
[11:21:22] <dirty_d> thats cool
[11:21:28] <dirty_d> but that turbine looks like it was milled
[11:21:55] <dirty_d> unless those ball end mill looking marks are on purpose
[11:22:06] <CaptHindsight> http://www.3ders.org/articles/20140928-nanosteel-announces-crack-free-dense-steel-powder-for-your-3d-metal-printer.html
[11:22:08] <archivist> dirty_d, you are not supposed to notice that
[11:22:17] <_methods> no he's probably buried
[11:22:17] <dirty_d> lol
[11:22:25] <_methods> i saw the freeway there was a parking lot
[11:23:36] <dirty_d> the borg cube looks legit
[11:26:33] <CaptHindsight> I have to try reflowing the single crystal superalloys
[11:27:30] <CaptHindsight> laser sinter powder, coat with ceramic mold, bake/reflow
[11:29:09] <SpeedEvil> Cool carefully from one end
[11:30:41] <archivist> pull through a melt
[11:36:48] <CaptHindsight> I wonder if IRC logs are/can be used as prior art?
[11:37:43] <archivist> anything published publicly I think
[11:39:53] <CaptHindsight> in the US it looks like "described in a printed publication published anywhere in the world prior to the patent applicant inventing it"
[11:40:21] <CaptHindsight> printed vs online
[11:41:28] <cpresser> well, you could write a bot to create pdfs from irc-log, sign them, and publish as epub
[11:41:52] <CaptHindsight> maybe there needs to be a monthly printed publication to block obvious patents
[11:42:08] * archivist points at the touch utility for sensible dates :)
[11:42:16] <CaptHindsight> but it all seems to be ignored by the examiners anyway
[11:43:05] <archivist> current examiners need to be made personally liable for mistakes
[11:51:26] <archivist> I think zeeshan would like one of these http://www.ebay.co.uk/itm/Clamping-Force-Gauge-for-CNC-milling-Machine-BT30-BT40-BT50-/261679317382
[11:54:05] <Loetmichel> sooo, weekend!... and the ebay notebook has finally arrived... even the keyboard starts working again after i rinsed out about a glass of pepsi or something out of it. Still has some ghost keys because of trapped water... should have used the compressed air nozzle longer ;-)
[11:54:35] <_methods> see pete is alive
[11:54:40] <ssi> peeet
[11:55:03] <CaptHindsight> out from his ice cave
[11:55:09] <_methods> or traffic jam lol
[11:56:51] <skunkworks> or someone stole his computer and just turned it on...
[11:59:05] <CaptHindsight> the news made it sound like the start of the apocalypse
[11:59:59] <zeeshan> archivist:
[12:00:03] <zeeshan> why do you post things so expensive for me
[12:00:08] <zeeshan> yet get all the cheap deals for yourself! :P
[12:00:13] <ssi> lol
[12:00:44] <zeeshan> i have a spare cat40 shank that i'd like to transform into a clamping gauge
[12:05:45] <CaptHindsight> zeeshan: http://www.ebay.com/itm/New-Powertronic-Portable-Power-Line-Quality-Disturbance-Voltage-Logger-w-Printer-/291101692004
[12:06:10] <zeeshan> lol
[12:06:11] <zeeshan> :D
[12:06:54] <DGMurdockIII> do anyof you use freecad?
[12:07:05] <CaptHindsight> zeeshan: did you get all that sorted out?
[12:07:13] <jdh> today is the last sub-freezing day in the 10 day forecast
[12:07:26] <CaptHindsight> DGMurdockIII: just for quickly viewing files
[12:07:52] <DGMurdockIII> what do you use for make you stuff you going to cut
[12:08:01] <DGMurdockIII> making
[12:09:00] <CaptHindsight> DGMurdockIII: people have been talking about http://www.google-melange.com/gsoc/org2/google/gsoc2015/brlcad
[12:09:10] <dr0w> DGMurdockIII: I've been mucking with freecad lately.
[12:09:43] <CaptHindsight> DGMurdockIII: but I use NX mostly, then SW, Creo, Catia etc
[12:10:16] <ssi> man I always wanted to try NX
[12:10:48] <DGMurdockIII> thanks between solidworks, freecad and brlcad i thnk i have that software bases coverd
[12:11:09] <DGMurdockIII> I have another qustion
[12:11:17] <DGMurdockIII> What do you think of mastercam
[12:11:35] <CaptHindsight> they all work about the same until you get into features, rendering and simulation etc
[12:11:37] <DGMurdockIII> I heard that not as good as it use to be
[12:11:42] <dirty_d> never heard of that before
[12:11:56] <ssi> NX is the only big package that has native osx support
[12:12:02] <DGMurdockIII> http://en.wikipedia.org/wiki/Mastercam
[12:12:07] <dirty_d> cam is the big missing thing on linux
[12:12:20] <dirty_d> there are usable cad programs, but really no cam
[12:12:23] <zeeshan> capt yes a long time ago :P
[12:14:07] <DGMurdockIII> is there som thing like Slic3r for generating the cnc code
[12:14:25] <dirty_d> sounds liek thats for 3d or 3d printing
[12:14:28] <_methods> no this actually takes skill
[12:14:30] <PetefromTn_> hello guys
[12:14:42] <ssi> lol
[12:14:46] <dirty_d> need a good 2.5d cam program
[12:15:00] <zeeshan> ssi did you see my laser videos!
[12:15:05] <zeeshan> no wonder you're so addicted to laser

[12:16:18] <ssi> zeeshan: no I didn't
[12:16:40] <ssi> but yes laser is awesome
[12:16:42] <CaptHindsight> just Heeks and PyCAM
[12:16:46] <ssi> I wish you'd come help me build this new frame
[12:16:48] <zeeshan> i want one
[12:16:50] <ssi> I'm having trouble :(
[12:16:56] <CaptHindsight> did Heeks stall out again?
[12:16:58] <DGMurdockIII> you guys know that Mach4 is going to support linux
[12:17:02] <PetefromTn_> https://www.youtube.com/watch?v=cU-eAzNp5Hw Jimmy Fallon is amazing...
[12:17:25] <CaptHindsight> PetefromTn_: how did you enjoy the storm?
[12:17:28] <PetefromTn_> Mach4 is dead before it even came out...
[12:17:37] <DGMurdockIII> why
[12:17:41] <PetefromTn_> Oh it was lovely.. rolleyes
[12:18:00] <DGMurdockIII> the price?
[12:18:31] <PetefromTn_> honestly despite all the weathermans predictions of ice and snow we barely got anything here thankfully but it did get pretty cold.
[12:18:31] <CaptHindsight> wow 50's F here next week
[12:18:34] <PetefromTn_> two days ago it was 65 here...GASP!
[12:18:47] <malcom2073> I just shoveled over a ft of snow, I don't wanna hear it :P
[12:19:05] <PetefromTn_> Oh that was the day before man!
[12:19:06] <skunkworks> DGMurdockIII, mach4 is going to do a lot of things..
[12:19:57] <DGMurdockIII> skunkworks, so u think it will be good
[12:20:18] <ssi> not sure how you got there from here
[12:20:42] <jdh> 80f yesterday
[12:20:43] <DGMurdockIII> ssi, u thalking to me
[12:20:51] <ssi> nah
[12:23:21] <skunkworks> DGMurdockIII, It isn't close to being a viable system yet. Just that it is supposed to have all these cool features that will get added in time..
[12:23:47] <CaptHindsight> mach3 hit my table
[12:24:58] <malcom2073> CaptHindsight: Mach4 can hit much more than your table!
[12:25:11] <ssi> mach3 hit my trash can
[12:25:56] <zeeshan> lets not forget path pilot
[12:27:39] <CaptHindsight> https://www.youtube.com/watch?v=DtLs5ky3m-s super hydrophobic and self-cleaning coatings
[12:28:18] <CaptHindsight> with subtitles in English :)
[12:28:27] <_methods> r kelly paint
[12:30:52] <PetefromTn_> https://www.youtube.com/watch?v=H6otmy3DAK8 Amazing Jimmy Fallon again...
[12:48:41] <dirty_d> hmm wonder if sprut cam is any good, they have a 30 day trial
[12:52:38] <_methods> looked pretty good to me
[12:52:42] <_methods> i've never used it though
[12:53:26] <LeelooMinai> dirty_d: You can watch some youtube videos of that Tormac guy using it - he is not very good at it, but still you can see how the thing works and what's the overall usability of it.
[12:57:05] <dirty_d> yea im gonna have to, i cant see where hte hell to actually create a machining operation
[13:12:27] <roycroft> i rarely stay up late enough to watch jimmy fallon but i happened to catch that night
[13:12:34] <roycroft> that was a pretty good performance
[13:12:44] <roycroft> but i don't think he'll ever beat "whip my hair" with the boss
[13:13:31] <roycroft> on the neil young night ellen degeneris was also on and they played celebrity password
[13:20:18] <FinboySlick> _methods: I'm fascinated reading that home made CO2 laser article.
[13:22:43] <_methods> yeah that guy did some great stuff
[13:23:00] <_methods> i think he based most of it off that laser guru guy
[13:23:12] <_methods> he's like a phd laser master
[13:24:42] <ssi> link?
[13:24:48] <ssi> I've seen some homemade co2 laser stuff in the past
[13:24:50] <XXCoder> heys
[13:24:53] <ssi> they're pretty simple
[13:25:03] <_methods> one sec i gotta find it again lol
[13:25:41] <_methods> http://www.jarrodkinsey.org/co2laser/co2laser.html
[13:25:54] <XXCoder> "first"
[13:26:11] <_methods> http://www.repairfaq.org/sam/lasersam.htm
[13:26:16] <_methods> and that guy
[13:27:00] <XXCoder> later in article its better, guy says "my first co2 laser"
[13:27:12] <_methods> http://repairfaq.cis.upenn.edu/Misc/sambio.htm
[13:27:28] <_methods> he's pretty much a laser god
[13:27:41] <XXCoder> I want laser cutter cnc
[13:28:01] <XXCoder> if Im getting frame as well as use my incompitable parts into small laser cutter
[13:28:13] <ssi> it's not hard to build a laser cutter
[13:28:20] <XXCoder> ball screws and sbr kit
[13:28:36] <ssi> I'm trying to decide how I want to build my new frame
[13:28:41] <ssi> having a lot of trouble with that :(
[13:28:50] <XXCoder> it is ard yeah
[13:29:00] <XXCoder> maybe build it in solvespace or something
[13:29:14] <XXCoder> something that can move parts so you can see limits and such
[13:29:32] <ssi> solvespace?
[13:29:47] <ssi> I've been trying to do it in solidworks but solidworks inside win7 inside parallels is being a huge turd for me :(
[13:29:49] <XXCoder> its amazing modeler yet pretty new
[13:30:04] <XXCoder> its bit hard on linux you gonna compile
[13:30:18] <XXCoder> http://solvespace.com/index.pl
[13:30:37] <_methods> http://arstechnica.com/tech-policy/2015/03/vmware-alleged-to-have-violated-linuxs-open-source-license-for-years/
[13:30:40] <_methods> ouch
[13:30:44] <XXCoder> yeah
[13:30:52] <ssi> I'm on osx
[13:30:56] <XXCoder> it will first test
[13:30:59] <XXCoder> oh
[13:31:10] <XXCoder> open source so maybe can make mac compitable
[13:31:17] <ssi> meh
[13:31:20] <XXCoder> its very new and developer is windows one
[13:31:20] <ssi> too much hassle :)
[13:31:32] <XXCoder> I want it to succeed because damn its good
[13:31:49] <XXCoder> maybe it will run better in parallels
[13:31:55] <XXCoder> than solidworks anyway
[13:32:31] <ssi> biggest problem I'm having with solidworks right now
[13:32:39] <ssi> I'm downloading sldprt files from mcmaster for tslot extrusion
[13:32:44] <ssi> and it renders HORRIBLY
[13:32:53] <_methods> yeah all those profiles
[13:33:03] <_methods> they're a nightmare lol
[13:33:12] <_methods> even on a real computer
[13:33:34] <ssi> I guess I don't have to model the tslot
[13:33:48] <ssi> but I was really hoping I could do some deflection analysis or something
[13:33:56] <_methods> i'll trade you a windows pc for one of your airplanes lol
[13:33:57] <XXCoder> can always do some points accurate shape, like accurate rod
[13:34:05] <XXCoder> and pretty good approx of supports
[13:34:09] <ssi> I don't want a windows pc!
[13:34:16] <_methods> hahahahah
[13:34:23] <ssi> shit I have a machine here under my desk that has two huge ridiculous video cards in it
[13:34:29] <ssi> I could make that a solidworks box if I really wanted to
[13:34:49] <_methods> yeah i keep 1 windows computer for all my cad/cam/gaming
[13:34:59] <_methods> everything else is bsd/linux
[13:35:06] <XXCoder> carefully isolated from rest eh? lol
[13:35:15] <XXCoder> in class AAA clean room
[13:35:33] <_methods> i think they're all equally vulnerable anymore
[13:35:40] <XXCoder> yeah
[13:35:45] <XXCoder> I use windows 7 pc
[13:35:54] <_methods> the *nixes have been just as plague ridden lately
[13:35:58] <XXCoder> computer itself is pretty damn elderly at 9+ years old
[13:36:19] <XXCoder> good thing I had bought riciously overkill compuyter back then
[13:36:19] <ssi> so my last laser table was built from 20x40mm extrusion for the main frame, and 20x20 legs and everything else
[13:36:21] <_methods> i like the *nixes because i can use old hardware and still get good performance
[13:36:34] <ssi> but it was 2x4' work area, and around 33x60" overall
[13:36:41] <XXCoder> ssi: laser cnc I bet I can almost use just sbr itself as supports
[13:36:43] <ssi> I want the new one to be 4x8' work area
[13:36:48] <ssi> sbr?
[13:36:52] <_methods> rail
[13:36:52] <XXCoder> expecially X since it has sbr 20
[13:36:54] <_methods> round rail
[13:36:54] <XXCoder> yeah
[13:37:04] <_methods> with split bearings
[13:37:07] <_methods> supported rail
[13:37:13] <ssi> that might not be a horrible option
[13:37:33] <ssi> well so I'm trying to decide if I want to build the frame itself from something like 40x80mm tslot, or just welded steel rectangle tube
[13:37:39] <XXCoder> its nice but if you buy chinsese shit ones, clear out bearings or buy usa ones and swap em.
[13:37:48] <_methods> steel is cheaper for sure
[13:37:58] <ssi> it's cheaper, but not tremendously so
[13:37:58] <XXCoder> and kess modifable
[13:38:12] <ssi> and building a decent FLAT table is going to be harder
[13:39:06] <_methods> indeed
[13:39:31] <ssi> and as far as extrusion goes, I'm pretty much limited to buying it from mcmaster
[13:39:34] <ssi> cause I can get it locally
[13:39:53] <XXCoder> I plan to just stright up buy from chinese
[13:39:57] <XXCoder> a frame
[13:40:07] <XXCoder> so I has working cnc to make bigger cnc
[13:40:10] <ssi> I thought about buying a cncrouterparts.com motion kit
[13:40:15] <ssi> but it's $4500
[13:40:18] <ssi> and not really optimized for laser
[13:40:39] <XXCoder> maybe it is better to just do 8020 yeah
[13:40:45] <XXCoder> tslot frame
[13:41:04] <XXCoder> since basically zero defection at cutting (besides weight of system)
[13:41:14] <jdh> and 1kw?
[13:41:20] <ssi> the system will be pretty light
[13:41:25] <_methods> lol
[13:41:26] <ssi> and there's no cutting forces
[13:41:33] <_methods> 80w
[13:41:55] <XXCoder> ssi: maybe get sbr rails for X
[13:42:03] <XXCoder> its very rigid and stright
[13:42:16] <XXCoder> it will help surface be flat
[13:42:25] <ssi> kind of expensive though
[13:42:39] <XXCoder> chinese its not too bad but buy usa bearings
[13:42:46] <ssi> I need 2800mm
[13:42:50] <ssi> and shipping that will be a nightmare :(
[13:43:29] <XXCoder> http://www.ebay.com/itm/250729742630 thats what I bought
[13:43:38] <XXCoder> lemme look at others at same store
[13:44:17] <XXCoder> http://www.ebay.com/itm/Linear-guide-linear-rail-SBR16-1200mm-4-rails-8-SBR16UU-blocks-SUR-/250708738280?pt=LH_DefaultDomain_0&hash=item3a5f67c0e8
[13:44:35] <XXCoder> 280 bucks for all that
[13:44:58] <XXCoder> you will have extra rails for other uses I guess
[13:46:24] <ssi> way too short for me tho
[13:46:32] <XXCoder> oops!!
[13:46:39] <XXCoder> somehow I recalled 1200mm
[13:47:21] <_methods> what are you gonna use?
[13:47:24] <_methods> that's a lot of rail
[13:47:49] <_methods> with no load on the head your could probably just use linear bearings and round rod
[13:47:57] <_methods> like a 3d printer head
[13:48:10] <XXCoder> yea
[13:48:14] <_methods> you just need something to keep deflection out
[13:48:21] <_methods> over that nightmare distance
[13:48:33] <XXCoder> sbr do give additioonal benefit on being very rigid
[13:48:39] <XXCoder> but 2800 mm wow
[13:49:12] <XXCoder> maybe some nice 1530 beams with bearing blocks
[13:49:23] <XXCoder> should be strong enough
[13:49:53] <XXCoder> dunno if can buy those blocks specifically for 1530 so maybe have to make
[13:50:24] <XXCoder> http://www.ebay.com/itm/4X-SBR16-2800mm-16MM-SUPPORTED-LINEAR-RAIL-SHAFT-8-Pcs-SBR16UU-Rounter-Bearing-/261398653002
[13:50:36] <XXCoder> 450 shipped approx
[13:51:10] <ssi> my last machine was makerslide
[13:51:13] <ssi> it worked pretty well
[13:51:14] <_methods> http://www.igus.com/wpck/5365/drylin_r_awui
[13:51:16] <XXCoder> twice as many as you need... maybe build two and sell one off for profit enough to cover both lol
[13:51:21] <_methods> wonder how much that stuff goes for
[13:51:24] <ssi> the gantry was 54" long, and plenty rigid enough for what I needed
[13:51:47] <_methods> yeah makerslide may actually be the way to go
[13:51:48] <ssi> I was thinking I'd do a 54" gantry again, and then do 110" long rails, rigidly affixed to the frame
[13:51:52] <_methods> probably way cheaper
[13:51:53] <ssi> and I can get all the makerslide for like $200
[13:51:58] <_methods> belts and maker slide
[13:52:00] <ssi> yep
[13:52:06] <XXCoder> nice
[13:52:10] <XXCoder> never heard of it
[13:52:24] <ssi> what sucks is, the way I did it before and what I intended to do again
[13:52:26] <_methods> it's just alum extrusion with a v on it
[13:52:30] <ssi> is buy a shapeoko kit and then extra long rails
[13:52:38] <ssi> but they recently stopped selling the shapeoko kit
[13:52:44] <ssi> they have a new product that's preordering now
[13:52:47] <ssi> D:
[13:52:49] <XXCoder> dont see any 2800mm on one site I found
[13:52:51] <_methods> aren't the drawings open source
[13:52:57] <zeeshan> where is andypugh!
[13:52:58] <_methods> for all the shapeoko stuff
[13:52:59] <ssi> they sell 1000 and 1800mm
[13:53:03] <ssi> and they'd be pretty easy to join
[13:53:07] <ssi> _methods: yeah they are
[13:53:12] <ssi> but the kit was a convenient way to go
[13:53:15] <_methods> true
[13:53:19] <ssi> and I don't have a great way to make those plates
[13:53:21] <_methods> but it's all laser cut plates
[13:53:25] <ssi> if I had a metal laser or a waterjet...
[13:53:29] <_methods> hehe
[13:53:34] <ssi> I have plasma table,
[13:53:36] <_methods> let me know what parts you need
[13:53:39] <ssi> but it can't do the internal holes well
[13:53:44] <_methods> i'll see what i can do
[13:53:46] <ssi> oo
[13:53:49] <ssi> what part of the world are you in
[13:53:50] <XXCoder> gonna love it when you need cnc to make cnc
[13:54:08] <XXCoder> ssi: start at middle and undercut holes? then somehow finish it
[13:54:11] <XXCoder> reamer maybe
[13:55:09] <ssi> does'nt work well sadly
[13:55:16] <XXCoder> oh drat
[13:55:16] <ssi> plasma hardens the edges a LOT
[13:55:27] <ssi> you end up wiping all the flutes off your drill bits :)
[13:55:29] <_methods> charleston sc
[13:55:36] <ssi> _methods: oh damn I could just come up :)
[13:55:42] <ssi> fly up even
[13:55:44] <ssi> an hour or so
[13:55:50] <_methods> yeah i'm right next to teh municipal airport
[13:55:52] <_methods> in summerville
[13:55:52] <XXCoder> https://www.inventables.com/projects/1000mm-x-1000mm-shapeoko-upgrade-kit
[13:55:56] <_methods> it's like 5 min from here
[13:56:07] <XXCoder> interesting,. too bad its closed out
[13:56:26] <ssi> https://www.inventables.com/technologies/x-carve
[13:56:29] <ssi> that's their new kit
[13:56:32] <ssi> but it's not available yet
[13:56:36] <ssi> it's very similar
[13:56:46] <XXCoder> yeah saw it
[13:56:56] <ssi> it looks nicer
[13:57:04] <XXCoder> didnt know it was shapeoko
[13:57:14] <ssi> they probably won't release the design files for the xcarve stuff til after it's shipping
[13:57:41] <ssi> https://github.com/shapeoko/Shapeoko_2
[13:57:46] <ssi> that's the design stuff for the shapeoko
[13:57:48] <XXCoder> z axis screw isnt held on bottom part
[13:58:05] <ssi> I don't have a z axis so I don't care :)
[13:58:12] <XXCoder> I guess it needs software defines or something
[13:59:11] <ssi> so the other part of my design struggle
[13:59:16] <ssi> is the Z-bed
[13:59:29] <ssi> I need to make a decent, rigid frame that'll hold a 4x8' sheet of MDF
[13:59:38] <ssi> that's supported on four acme screws
[13:59:50] <ssi> I'm wondering if just the screws are enough, or if it needs linear guides as well
[14:00:12] <XXCoder> try deflection test on acme screws
[14:00:29] <XXCoder> you know what material you need to cut so can figure from there I guess
[14:00:45] <ssi> again, no cutting forces
[14:00:56] <XXCoder> no, the weight of stock on toop
[14:00:57] <ssi> and the acme screws will be vertical
[14:01:00] <ssi> so they dno't really deflect
[14:01:06] <XXCoder> no issue then
[14:01:16] <SpeedEvil> you mean for a Z bed?
[14:01:18] <ssi> I'm more wondering whether the table will move around slightly as the bed is raised and lowered if I don't have rail
[14:01:22] <ssi> SpeedEvil: yes
[14:01:54] <SpeedEvil> ssi: constraining it in xy is probably a good idea. This can be quite simple
[14:02:13] <SpeedEvil> Four drawer slides, and a couple of springs
[14:02:38] <ssi> SBR rail might be a good option for that part
[14:02:45] <ssi> I only need 12" of throw
[14:03:17] <XXCoder> small sbrs is cheap
[14:03:26] <XXCoder> sbr12 is good I bet
[14:04:03] <ssi> lemme start drawing someting up without fully-modeled t-slot
[14:04:17] <ssi> my ADD is making this extremely difficult :)
[14:04:23] <zeeshan> =]

[14:04:31] * zeeshan slaps ssi to pay attention
[14:04:32] <ssi> I have like six things going through my head at the same time
[14:04:34] <XXCoder> 24 bucks each, free shupping
[14:04:55] <ssi> laser frames, mini arc furnaces, acoustic guitars, docker container deployment systems, whores
[14:05:09] <_methods> hahahah
[14:05:11] <_methods> mini arc
[14:05:18] <ssi> I want to build taht bastard really bad
[14:05:25] <_methods> i still need to go beg for refractory brick
[14:05:27] <XXCoder> heres new one for you ssi heh arc speakers
[14:05:36] <ssi> I'm familiar with arc speakers
[14:05:36] <_methods> i got the gouge rods already
[14:05:38] <ssi> don't need that right now :)
[14:05:40] <ssi> _methods: :D
[14:05:53] <ssi> I haven't decided if I'm gonna make a mcmaster run tomorrow morning or just go to walmart and buy lantern batteries
[14:05:54] <XXCoder> http://www.noiseaddicts.com/2009/04/plasma-speakers/
[14:05:57] <ssi> I already have a firebrick
[14:06:03] <XXCoder> 'sorry late :)
[14:06:14] <ssi> I guess if I get really desperate I can fly to charleston and scam you out of a pair
[14:06:17] <ssi> haha
[14:06:29] <_methods> yeah we got piles of em
[14:06:41] <_methods> hardly worth the flight lol
[14:06:44] <zeeshan> http://www.ebay.ca/itm/1PCS-BF350-3AA-BF350-Precision-resistive-strain-gauge-strain-gauge-/181497093061?pt=LH_DefaultDomain_0&hash=item2a4211dbc5
[14:06:47] <zeeshan> gotta love the chinese
[14:06:47] <XXCoder> too bad im billion miles away lol
[14:06:51] <zeeshan> the gauge factor
[14:06:52] <ssi> I love to fly :)
[14:06:54] <zeeshan> is given as 2.0 - 2.20
[14:06:55] <zeeshan> ROFL
[14:06:56] <zeeshan> its a range
[14:07:21] <zeeshan> was it too hard for some they say +/- 1%
[14:07:30] <ssi> that's 10% tho :)
[14:07:34] * zeeshan stops ranting
[14:07:55] <zeeshan> youre right
[14:07:56] <zeeshan> 10%
[14:07:56] <XXCoder> yea should be +- 0.5
[14:08:01] <zeeshan> terrible
[14:08:04] <ssi> _methods: 1:24 in the RV6
[14:08:07] <zeeshan> good ones are 1%
[14:08:11] <_methods> heheh
[14:08:19] <XXCoder> oops
[14:08:24] <XXCoder> 10% dang
[14:10:15] <zeeshan> youre both right :P
[14:10:21] <zeeshan> you gotta state the base number to make sense
[14:10:25] <zeeshan> 2.1 +/- 5%
[14:10:30] <zeeshan> or 2.0 +10%
[14:10:35] <zeeshan> or 2.20 -10%
[14:10:35] <zeeshan> :P
[14:10:45] <XXCoder> I always like midpoint better
[14:10:49] <zeeshan> me too
[14:10:57] <XXCoder> unless it is really really critical not to go below or above
[14:11:03] <zeeshan> all depends
[14:11:09] <zeeshan> i like absolute limits in that case
[14:11:37] <XXCoder> saw many parts that has this - example 0.1" -0.000 +0.02
[14:12:18] <_methods> ah sweet i think tractor supply has refractory bricks
[14:12:28] <_methods> gonna go hit them tomorrow after i watch chappie i guess
[14:12:34] <ssi> nice
[14:12:40] <XXCoder> forge related?
[14:12:47] <_methods> mini forge
[14:12:55] <XXCoder> nice
[14:12:57] <_methods> or furnace i should say
[14:12:59] <_methods> not forge
[14:13:03] <XXCoder> I do want to build furance
[14:13:27] <XXCoder> maybe just buy pottery kilnb
[14:13:38] <ssi> I had a pottery kiln
[14:13:38] <XXCoder> I want to melt glass as well as alum
[14:13:46] <ssi> but I sold it to someone who was supposed to let me use it
[14:13:50] <ssi> but then they decided they hated me
[14:13:50] <ssi> :(
[14:14:00] <XXCoder> jeez
[14:14:07] <ssi> oh god
[14:14:13] <ssi> obama is gonna be at gatech on tuesday
[14:14:16] <ssi> I guess I'm not going to work
[14:14:29] <XXCoder> why?
[14:14:38] <ssi> because it'll be impossible to drive
[14:14:56] <XXCoder> ahh was thinking you had something against him or something
[14:15:01] <XXCoder> but yeah hell on roads
[14:15:07] <ssi> well I do, but that doesn't impact my decision :)
[14:15:25] <_methods> hahahha
[14:15:40] <XXCoder> great presidents its too bad only 2 term limit, bad presidents be glad its 2 term limit
[14:15:43] <XXCoder> it breaks even
[14:15:58] <XXCoder> speaking in general
[14:20:37] <CaptHindsight> http://www.pcmag.com/article2/0,2817,2477880,00.asp Lockheed Martin Laser Stops Truck in its Tracks
[14:21:00] <XXCoder> CaptHindsight: use it for laser cutter ssi ;)
[14:21:12] <ssi> I WANT THAT
[14:21:13] <ssi> :D
[14:21:42] <FinboySlick> "The vehicle, hoisted onto a test platform, was running its engine and drive train, simulating a real-life military scenario."
[14:22:06] <FinboySlick> Riiight.
[14:22:17] <XXCoder> would you drive it directly?
[14:22:23] <XXCoder> when youre inside range
[14:22:54] <XXCoder> though not sure why not use remote rig like Adam Savage used
[14:24:10] <XXCoder> though wonder if this https://en.wikipedia.org/wiki/Retroreflective_sheeting using mirrors would send laser back to source lol
[14:24:20] <CaptHindsight> or use Jeremy from TopGear :)
[14:24:22] <XXCoder> before it heated up and explode anyway
[14:24:28] <XXCoder> lol
[14:25:03] <FinboySlick> So this is why they drive chrome-plated Ferraris in Dubai.
[14:25:14] <_methods> hahaha
[14:25:19] <_methods> pew pew
[14:25:26] <XXCoder> lo
[14:25:58] <XXCoder> https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment#mediaviewer/File:ALSEP_AS15-85-11468.jpg
[14:26:17] <XXCoder> that is retrorefective so laser shot from earth would return
[14:27:24] <CaptHindsight> http://www.lockheedmartin.com/us/news/press-releases/2015/march/ssc-space-athena-laser.html
[14:29:12] <FinboySlick> "The Corporation’s net sales for 2014 were $45.6 billion." Or about 3 million, if you omit taxpayer money.
[14:29:30] <CaptHindsight> exactly
[14:29:58] <CaptHindsight> it should be field ready by 2030
[14:30:48] <CaptHindsight> "spectral beam combining, multiple fiber laser modules form a single, powerful, high-quality beam that provides greater efficiency and lethality than multiple individual 10-kilowatt lasers used in other systems."
[14:31:22] <FinboySlick> I'm a bit curious of what they mean by fiber-optics lasers though. I mean, it's pretty obvious that you can run a laser through fiber-optics but obviously they don't just mean taping the ends of fiber-optics cables side by side to make a 'bigger laser'.
[14:32:06] <CaptHindsight> it basically is that
[14:32:31] <CaptHindsight> only precisely and in an optimal way, not just duct tape
[14:33:10] <CaptHindsight> it's more fancy optics than gancy lasers
[14:33:18] <CaptHindsight> gancy/fancy
[14:33:32] <ssi> FinboySlick: a fiber laser uses a fiber as the resonator, not as the beam path
[14:34:32] <SpeedEvil> Spectral beam combining gets round the fact that you can't simply combine two identical frequency beams
[14:35:02] <furrywolf> hrmm. my linode rebooted itself.
[14:35:23] <SpeedEvil> Fibre coupled laser modules, tuned to different frequencies, arecombined into one beam ina way you can't do with single frequency
[14:35:54] * furrywolf would be much happier if the technology was being used to help people, not kill them
[14:36:18] <ssi> they're not killing people, just trucks :P
[14:37:14] <furrywolf> right... and guess what they then do to the people in the trucks?
[14:37:22] <_methods> i'll have to look at that shapeoko stuff this wknd maybe i'll cut out a couple next week
[14:37:22] <ssi> give them cake
[14:37:39] <ssi> _methods: that'd be sweet
[14:37:51] <_methods> yeah if i remember right there's not much to it
[14:37:53] <ssi> for my stuff, I basically need four of the gantry plates and two of the end plates
[14:37:56] <ssi> maybe four
[14:38:02] <_methods> k
[14:38:17] <ssi> and I think they're 1/8" steel
[14:38:29] <_methods> yeah i got that all over the place
[14:38:34] <_methods> and the plates are small
[14:38:40] <_methods> so i can get them out of drops
[14:38:45] <XXCoder> furrywolf: hey
[14:38:48] * furrywolf especially thinks the US government shouldn't have such technology, given as they have a rather well proven track record of trying to fuck over random other countries
[14:39:08] <_methods> the x and z plates are identical?
[14:39:23] <ssi> yes
[14:39:27] <_methods> ah cool they got it all in solidworks
[14:39:30] <ssi> yeah
[14:39:38] <_methods> even better
[14:39:48] <_methods> downloading git now
[14:40:04] <SpeedEvil> furrywolf: think of the future!
[14:40:11] <_methods> they're not that bad for what they are
[14:40:28] <SpeedEvil> Cities,with one central lasercutter turret that you just have to hold up your workpiece in the line of sight, and dial in.
[14:40:33] <ssi> yeah I'm pretty impressed with the motion system
[14:40:36] <ssi> for simple stuff like this
[14:40:40] <ssi> I wouldn't want to run a real router on it
[14:40:44] <_methods> oh no
[14:40:50] <_methods> all i've ever cut on one was foam
[14:40:58] <ssi> yeah
[14:41:02] <ssi> and for flying optics it's FINE
[14:41:18] <XXCoder> whats shaped foam for
[14:41:26] <ssi> all sorts of stuff
[14:41:43] <CaptHindsight> http://img.izismile.com//img/img2/20091110/armor_piercing_shell_00.jpg look at these holes made by conventional armor piercing rounds
[14:41:59] <ssi> I would like to make a four joint CNC hotwire
[14:42:04] <ssi> for cutting foam airfoils
[14:42:05] <XXCoder> i know. I was specifically asking what he uses it fot
[14:42:15] <ssi> for doing moldless composite wing consctruction
[14:44:17] <XXCoder> damn
[14:44:26] <XXCoder> laser gods abusing ballon to mix gases
[14:44:29] <XXCoder> genius
[14:44:31] <_methods> oh i was just using it to teach people how to program cnc machines at the local makerspace
[14:44:37] <XXCoder> definitely better than guessing]
[14:44:40] <XXCoder> noce
[14:44:41] <ssi> XXCoder: yeah I've seen that method
[14:46:31] <dirty_d> man, sprutcam is not intuitive at all
[14:50:12] <Cromaglious> Hmm looking at a TB6600 driver board 4.5amp no 5v required 12-45v and it runs at alot high frequency..
[14:50:23] <dirty_d> no
[14:50:24] <dirty_d> lol
[14:50:26] <dirty_d> dont buy those
[14:50:32] <ssi> agreed
[14:50:39] <_methods> weird looks like the made shapeoko plates out of .100" lol
[14:50:52] <ssi> _methods: hah yeah maybe so
[14:50:57] <ssi> that's what, like 11 gauge?
[14:51:00] <_methods> almost
[14:51:01] <_methods> lol
[14:51:02] <dirty_d> actually the ones youre looking at might not be the same as the shitty ones i got
[14:51:03] <ssi> it's not really critical
[14:51:06] <ssi> 1/8" is probabyl FINE
[14:51:10] <_methods> 11 is like .114"
[14:51:16] <_methods> more like 12 ga
[14:51:23] <_methods> which is kinda odd size
[14:51:23] <ssi> or whatever you have around
[14:51:35] <Cromaglious> is it better than a TB6560?
[14:51:36] <_methods> you don't see many people use 12ga unless they don't know what they're doing
[14:51:38] <ssi> maybe they used 2.5mm
[14:51:56] <_methods> i'll just use 11ga
[14:52:02] <_methods> everything is outside
[14:52:14] <_methods> it shouldn't throw anything off by going thincker
[14:52:17] <_methods> thicker even
[14:52:30] <dirty_d> Cromaglious, these? http://www.pibot.com/3d-printer-store/3d-printer-electronic/pibot-stepper-driver-rev2-2.html
[14:52:34] <dirty_d> those actually dont look bad
[14:52:53] <dirty_d> dont buy these http://www.ebay.com/itm/TB6600-CNC-Single-Axis-0-2-5A-Two-Phase-Hybrid-Stepper-Motor-Driver-Controller-/221462145308?pt=LH_DefaultDomain_0&hash=item33902c291c
[14:53:06] <_methods> it's got a ton of annoying hardware in it
[14:53:08] <ssi> yeah it' wont hurt anything to be thicker
[14:53:12] <XXCoder> the laser site suggests pre-1983 copper pennies. I suggest just buying and cutting penny shaped copper from sheet
[14:53:19] <_methods> gonna cost a fortune for all those damn vbearings
[14:53:37] <_methods> i have everything else on hand though
[14:54:28] <_methods> except all that makerslide
[14:54:47] <ssi> yeah they charge way too much for the v bearings too :(
[14:55:02] <ssi> that's why what I used to do was just buy a shapeoko kit and throw away the rails and bed and Z axis
[14:55:18] <_methods> hahah
[14:55:36] <ssi> but they don't sell them now, all of a sudden
[14:55:41] <ssi> my friend dennis just bought one two weeks ago
[14:55:43] <ssi> and now they're gone :(
[14:55:44] <_methods> you can't get teh vbarings for cheap on ebay?
[14:55:54] <ssi> I dunno
[14:55:58] <_methods> me either
[14:56:14] <_methods> i've avoided this makerslide crap like the plague till now
[14:56:19] <ssi> their v bearings are just plastic injection molded rings that skate bearings are pressed into
[14:56:40] <_methods> oh
[14:56:46] <_methods> so they're just plastic v's?
[14:56:49] <_methods> uhmw?
[14:56:54] <ssi> I think they're abs
[14:56:54] <ssi> heh
[14:57:07] <_methods> hmmmm
[14:57:27] <_methods> might have to just make my own
[14:57:32] <XXCoder> yeah mill it out
[14:57:41] <XXCoder> ssi: and expensive?? jeez
[14:57:58] <ssi> yeah they want something like $7.50 apiece
[14:58:02] <_methods> wtf
[14:58:05] <XXCoder> insane
[14:58:11] <XXCoder> molds can be expensive
[14:58:15] <XXCoder> like $10,000
[14:58:16] <_methods> oh wow i'll just get a stick of uhmw
[14:58:18] <XXCoder> but still too much
[14:58:25] <_methods> cut my own lol
[14:58:29] <ssi> sorry $4.95 apiece
[14:58:32] <ssi> or $75.50 for 20
[14:58:35] <ssi> https://www.inventables.com/technologies/dual-bearing-v-wheel-kit
[14:58:46] <ssi> and looks like they're delrin
[14:58:50] <_methods> ahh cool
[14:58:57] <_methods> i'll just get a stick of delrin then
[14:59:07] <ssi> you have a cnc lathe?
[14:59:13] <_methods> nah i'll do it manual
[14:59:16] <ssi> I can get the HNC running and make a ton of them
[14:59:19] <ssi> trade you wheels for plates :)
[14:59:24] <_methods> face, vgroove, part
[14:59:30] <_methods> rinse wash repeat
[14:59:41] <_methods> i'll just make a custom hss groove tool
[14:59:49] <_methods> haah you got it
[14:59:58] <_methods> i'll cut some plates on monday
[15:00:09] <ssi> :D
[15:00:19] <ssi> I need to get an oven set up so I can powdercoat them
[15:00:30] <_methods> ah yeah that would be nice
[15:00:44] <_methods> i might talk to the boss and see if i can just cut a sheet of them
[15:01:00] <_methods> i know a couple people that wouldn't mind having a shapeoko too
[15:01:24] <XXCoder> how hot do powder coat require?
[15:01:30] <ssi> 400ish
[15:01:34] <ssi> F
[15:01:34] <XXCoder> to cure and all ahh ok
[15:01:37] <_methods> i can get them powdercoated too
[15:01:42] <XXCoder> oven can do it
[15:01:46] <_methods> might be a couple dollars each
[15:01:47] <ssi> yeah I just need a shop oven :)
[15:01:57] <XXCoder> to bake shop cakes!
[15:02:02] <XXCoder> only cakes is a lie :(
[15:02:03] <_methods> i'll have to ask our powdercoater
[15:02:11] <Cromaglious> Looking at http://www.ebay.com/itm/4-5A-TB6600-Axis-CNC-controller-stepper-motor-driver-board-CNC-Controls-/261802293888?pt=LH_DefaultDomain_0&hash=item3cf4a1fa80
[15:02:32] <_methods> if you don't care about the color i might be able to get it done for pretty cheap
[15:02:38] <ssi> I don't care about the color
[15:02:40] <_methods> get him to throw them in with some other batches
[15:02:44] <_methods> cool
[15:02:50] <ssi> the other thing that's gonna suck is the eccentric nuts
[15:02:54] <dirty_d> damnit, im just gonna make my own CAM program with some kinda integration with solvespace
[15:02:55] <ssi> https://www.inventables.com/technologies/eccentric-spacer?recommended=product
[15:02:57] <_methods> well i'll try and get them coated then
[15:03:06] <ssi> I guess I can make those too
[15:03:07] <XXCoder> dirty_d: solvespace can do 2d cam
[15:03:14] <dirty_d> XXCoder, yea i need 2.5D
[15:03:18] <XXCoder> they said will evenually work in more
[15:03:33] <dirty_d> XXCoder, have you tried it yet?
[15:03:38] <XXCoder> solvespace
[15:03:40] <XXCoder> hell yes
[15:03:44] <dirty_d> i cant see where the hell you export gcode
[15:03:50] <dirty_d> i mean the toolpath generation
[15:04:07] <XXCoder> I love it, need to learn more. oh you must look in 2d mode (lines and such) then export, gcode
[15:04:10] <dirty_d> taht makes more sense, maybe i can make it better
[15:04:25] <dirty_d> oh, hmm
[15:04:33] <dirty_d> tehres just global settings for tool diameter etc
[15:04:57] <dirty_d> it must just output profiling operations huh?
[15:05:22] <_methods> heh maybe i should start making shapeoko free kits for laser builders
[15:05:26] <XXCoder> more or less apparently
[15:05:42] <ssi> heheh that sounds like a grand idea
[15:05:43] <dirty_d> kidna useless for 2.5d
[15:05:43] <XXCoder> you can do anything with 2d shape like cut out or engrave
[15:06:02] <_methods> just the plates
[15:06:12] <_methods> and maybe bearings and wheels i guess
[15:06:40] <XXCoder> that looks fun lol https://www.youtube.com/watch?v=nMveq3arey8
[15:07:05] <_methods> are they using 628zz bearings on those things?
[15:07:49] <_methods> i'll have to look at the design closer this wknd
[15:08:03] <_methods> wtf is up with those spacers on the z axis
[15:08:09] <_methods> 2 part spacer?
[15:08:19] <XXCoder> link?
[15:08:28] <ssi> you mean the gantry carriage?
[15:08:29] <_methods> the shapeoko
[15:08:30] <_methods> yeah
[15:08:37] <ssi> it's just two standard aluminum spacers together
[15:08:38] <_methods> that z carriage is a disaster
[15:08:44] <ssi> to get the requisite spacing
[15:09:00] <_methods> why not just make it 1 piece
[15:09:02] <_methods> crazy
[15:09:16] <ssi> I'm sure they're just buying off the shelf sizes
[15:09:21] <XXCoder> twice parts, twice varation of size
[15:10:06] <ssi> hm
[15:10:20] <ssi> I applied a registry patch to allow hardware accel inside parallels and now solidworks seems to be behaving MUCH better
[15:10:39] <XXCoder> nice
[15:10:43] <_methods> man i should really redesing it to use regular alum extrusion that you put the v on there with a router and pilot bearing
[15:10:58] <ssi> that might be really nice actually
[15:11:12] <_methods> that way anyone can do it with off the shelf extrusions
[15:11:16] <_methods> no makershit
[15:11:33] <ssi> or for that matter it could just be a 20x40mm extrusion with a carriage that puts a bearing in the tslot on top and bottom
[15:11:36] <ssi> I've seen something similar
[15:11:43] <ssi> especially if you made a delrin wheel which was a V but the other way
[15:11:46] <_methods> yeah
[15:11:58] <_methods> hmmm cut a chamfer in the slot
[15:12:01] <_methods> to aid teh v
[15:12:11] <ssi> you could, but Id on't think it'd even really be necessary
[15:12:14] <ssi> they have a radius as is
[15:12:15] <_methods> yeah
[15:12:22] <_methods> i'll have to look into this
[15:12:23] <ssi> lemme draw something up
[15:12:33] <_methods> i hate to give those maker tards any business
[15:13:34] <ssi> yeah I was happy to use them before they killed off the simple kit
[15:13:38] <ssi> now, fuck them, let's make something better
[15:13:43] <_methods> agreed heheh
[15:14:02] <ssi> I'd like to design around 20x40mm extrusion
[15:14:04] <ssi> mcmaster stocks it, it's cheap
[15:14:14] <ssi> that's the same size as the makerslide extrusion
[15:14:29] <_methods> ok
[15:16:08] <_methods> what's the openbuild laser gantry like
[15:16:19] <_methods> i forget been awhile since i've looked at theirs

[15:17:41] <_methods> hah that is about as simple as it gets
[15:18:07] <ssi> I can't tell how the motion works
[15:18:13] <_methods> yeah
[15:18:17] <_methods> i don't think it does lol
[15:18:24] <_methods> but i like the plate up top likethat
[15:19:56] <_methods> http://www.buildlog.net/sm_laser/drawings.html
[15:20:15] <zeeshan> http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/pQwAAOxy2CZTX8GX/$_57.JPG
[15:20:18] <zeeshan> anyone use one of these before?
[15:20:35] <_methods> touch sensor?
[15:20:45] <XXCoder> no idea what im looking at
[15:21:24] <zeeshan> strain gage
[15:21:30] <zeeshan> in bridge formation
[15:21:31] <zeeshan> looks like
[15:23:41] <PCW> XY strain gauge
[15:24:42] <_methods> http://www.buildlog.net/blog/wp-content/uploads/2011/02/xy_mech.jpg
[15:25:08] <ssi> that looks pretty good
[15:25:11] <_methods> yeah
[15:25:14] <XXCoder> it do
[15:25:21] <XXCoder> laser eh
[15:25:24] <_methods> i'll have to draw it all up this wknd
[15:25:33] <ssi> i'm working on some of it now
[15:25:37] <ssi> sw is behaving SOOOO MUCH BETTER
[15:28:00] <XXCoder> glad you found solution :D
[15:37:43] <Cromaglious> zeeshan, lathe working better yet?
[15:42:15] <Crom> eff hell solder flux bottle fell over now I have gouye stuff all over my bench
[15:43:11] <Crom> well that 10 port USB hub on ebay is low speed only Grrrr
[15:46:35] <ssi> _methods: https://pbs.twimg.com/media/B_cbaiTWAAAuY7J.png:large
[15:46:41] <ssi> https://pbs.twimg.com/media/B_cbW71WYAAhobU.png:large
[15:46:47] <ssi> with some slotting to takeup the gap
[15:46:51] <ssi> which I haven't modeled yet
[15:47:23] <ssi> could be three bearings instead of four
[15:47:32] <XXCoder> you just made those?
[15:47:36] <ssi> yep
[15:47:44] <XXCoder> damn it probably would take me hour lol still new
[15:48:09] <XXCoder> would you mill t slot in order tp have nice v groove?
[15:48:23] <ssi> nah I think a delrin V wheel would run in the radiused tslot just fine
[15:48:34] <XXCoder> yeah
[15:49:04] <ssi> and _methods seems to like the idea of running it horizontally like that, but I think the gantry will deflect less if it's vertical
[15:50:18] <XXCoder> bad case of white virus http://www.theloop.ca/store-owner-forgets-to-lock-up-overnight-customers-respond-in-the-most-canadian-way-possible/
[15:50:45] <_methods> yeah it may not be good up there like i was thinking
[15:50:55] <_methods> was an interesting idea
[15:51:21] <ssi> I think it's fine either way, but that 20x40 is gonna be MUCH stiffer in the 40mm direction than the 20mm direction
[15:51:32] <_methods> yeah
[15:51:32] <ssi> so just to minimize sag in the gantry, I think that'd be the way to go
[15:51:47] <XXCoder> ssi: maybe interesting idea for you - make your laser platform lower/rise cnc axis too
[15:51:59] <ssi> I don't want to move the motion up and down
[15:52:05] <ssi> because then I'd have to move the TUBE also
[15:52:09] <ssi> or else have an extra bend in the path
[15:52:10] <_methods> yeah
[15:52:12] <ssi> and that sucks
[15:52:14] <_methods> better to move the bed
[15:52:33] <XXCoder> hmm maybe not, but in least motorized lol but youre right
[15:52:59] <_methods> you don't want to be moving your beam path if you can avoid it
[15:53:15] <ssi> right
[15:53:16] <_methods> better to move the workpiece
[15:53:21] <ssi> all sorts of alignment issues there
[15:53:24] <_methods> yes
[15:53:34] <ssi> I got pretty good at aligning my beampath btw :)
[15:53:45] <ssi> it took me a little while at first, but I got VERY good at it
[15:53:46] <_methods> hehe i hate that
[15:53:53] <_methods> tweakin mirrors
[15:54:15] <ssi> also I never had a good method for aligning the mirror in the head before
[15:54:21] <ssi> but with a motorized Z I will be able to
[15:54:49] <ssi> anyway I'm gonna get on the road now
[15:54:50] <ssi> back in a bit
[15:54:56] <_methods> yeah i'm headin home
[15:54:57] <_methods> later
[15:55:26] <XXCoder> http://www.eliomotors.com/press-release-elio-motors-unveils-engine-prototype/

[16:33:35] <PCW> $39 Ebay 7800SFF latency
[16:33:37] <PCW> http://ibin.co/1tvw7XXOBsz3
[16:36:34] <Cromaglious> I have a DC7600SFF
[16:37:46] <Cromaglious> $15.99 DC7800 MB no CPU
[16:38:23] <PCW> add a E8500 for another ~$13 and you have a nice linuxcnc machine
[16:40:02] <PCW> someone (ttrj?) had a lot of trouble with his DC7800 but this one seems fine
[16:40:58] <PCW> ( thats RTAI will try Preemt-RT next )
[16:42:45] <PCW> latency test showed a 25 usec latency spike when starting iceweasel
[16:42:47] <PCW> histogram is with 10 glxgears and hd youtube video
[16:44:21] <Cromaglious> yeah my touch probe is on the way!
[17:08:52] <zeeshan> http://c1.staticflickr.com/9/8669/16737064025_70835c7d67.jpg
[17:09:03] <zeeshan> i think if i mount a strain gauge on the green part of the shaft
[17:09:15] <zeeshan> it will make a decent clamp meter
[17:19:43] <furrywolf> meh.
[17:19:45] * furrywolf is a bad wolfy
[17:20:06] <furrywolf> I was working outside, got hot, and decided to swing by the local market and grab some ice cream... got a carton... which is now gone.
[17:22:43] <PCW> and .... drumroll... the DC7800SFF runs hm2_eth at 4 KHz!
[17:25:09] <furrywolf> "The HP DC7800 SFF PC features a fast Intel Core 2 Duo processor, which means you'll always be working at the fastest speeds." ... that's from a current page, not a historical now-out-of-stock one. lol
[17:26:03] <furrywolf> gah, I can add Staples to my list of websites never to do business with. you try reading a page, and it starts animating a 2x4" orange box, one pixel at a time, using 100% cpu and blocking what you're trying to read.
[17:26:10] <PCW> well its not bad for $39.00
[17:26:24] <furrywolf> $39? staples wants $223. lol
[17:33:21] <furrywolf> what possibly makes webdesigners think that annoying users will benefit them? when a website displays a big box blocking the content I'm trying to read, I don't sign up for their mailing list, get coupons, or whatever other pointless shit is in the box - I hit back and go to a different site.
[17:40:45] <Cromaglious> ugh... reading up on the NT65-3x TB6560 controller in the YooCNC 3040... Guess I get to take it out yet again and add even more caps and resisters to it
[17:41:28] <furrywolf> I've heard exactly nothing good about those chinese controller boards.
[17:41:59] <Cromaglious> http://perweb.dk/CNCForum/YooCNC-Contr1.JPG http://perweb.dk/CNCForum/YooCNC-Contr2.JPG http://perweb.dk/CNCForum/YooCNC-Contr3.JPG
[17:42:26] <archivist> zeeshan, it looked shiny and make one for meeeee too
[17:43:46] <furrywolf> Crom: I've also heard they sent a crap drive waveform to the toshiba chip, power up the power rails in the wrong order, go into idle current mode even when they're not idle, and about a hundred other complaints, depending on which chinese board it is...
[17:47:12] <furrywolf> "THE BUYER MUST ALLOW 10 TO 12 WEEKS FROM THE PURCHASE DATE BEFORE THESE PLANTS WILL BE READY TO SHIP. THE PLANTS NEED TO HAVE TIME TO GROW. YOU WILL BE CONTACTED TO SCHEDULE YOUR SHIPPING DATE." ... grow-on-demand? lol
[17:47:53] <Jymmm> what KIND of plants?
[17:48:03] <LeelooMinai> You need water plants and wait for them to grow.
[17:48:28] <Jymmm> furrywolf: There are these wonderful things called SEEDs too =)
[17:48:29] <LeelooMinai> Sounds pretty reasonable to me:)
[17:48:32] <furrywolf> Jymmm: Brainstrain peppers
[17:48:38] <furrywolf> Jymmm: it's too late to start from seed here
[17:48:55] <furrywolf> seeds were about three months ago
[17:49:05] <Jymmm> furrywolf: hogwash! Just need to hothouse them
[17:49:41] <Jymmm> furrywolf: have a growlight?
[17:50:28] <furrywolf> again, it's too late. if you start from seed now, they won't ripen any fruit before next winter. the hot peppers all need a very long season...
[17:50:43] <furrywolf> to get hot peppers here, you have to start them indoors around the new year
[17:51:21] <Jymmm> Optimimally, yes. but you CAN do it semi off season too
[17:51:32] <Jymmm> Just not as high a yield.
[17:51:39] <furrywolf> ... I have been growing peppers here for a number of years. how long have you been growing peppers here for?
[17:52:11] <_methods> oh snap
[17:52:12] <Jymmm> your years plus one day.
[17:52:14] <_methods> pepper fight
[17:52:36] <_methods> pepper farmer fight
[17:52:50] <Jymmm> furrywolf: So, do you wish to continue your drama fest, or just have a nice conversation?
[17:52:51] <furrywolf> some varieties will happily overwinter in the greenhouse. Manzanos are excellent at it, for example. but the really hot ones don't seem to make it through the winter, even in the greenhouse, and to get ripe fruit, you have to start the seeds very early. since I didn't get seeds started this year, I'm buying starts.
[17:53:58] * Jymmm cross pollinates _methods CNC with thai chili peppers
[17:54:14] <_methods> heheh
[17:54:34] <_methods> i know absolutely only one thing about peppers
[17:54:41] <_methods> they burn when they leave the building
[17:55:00] <Jymmm> _methods: the smaller they are, the nastier they are =)
[17:55:23] <furrywolf> I think this year the only hots I had survive are a few scorps... haven't cleared out the greenhouse and taken inventory yet though. they might be ghost, not scorp.
[17:55:35] <Crom_> Good thing I'm allergic to them
[17:56:26] <Crom_> No Nightshade's of any in my diet
[17:56:34] <Crom_> Kind
[17:56:58] <furrywolf> smallest I have are tepin, another variety which overwinters well... I've never gotten more than 2-3 peppers a season from them though, and they're the size of peas, which kinda limits their usefulness. I'm hoping to get a better harvest this year.
[17:57:23] <Jymmm> furrywolf: I want to be one of the million others that has their own colorfully named hot sauce. but unlike "Death", "Satan Sauce" etc, I want to name mine "Mommy". Cause that is what you will be calling for when you just get a wiff of it =)
[17:59:00] <Crom_> My wife grows some heritage tomatoes which she likes, now we have 4 volunteer plants in the backyard outside the planters
[18:01:43] <furrywolf> I've had bad luck with tomatoes here... blight is everywhere.
[18:02:22] <furrywolf> and I've yet to get a single melon, ever. I've given up trying. no cantaloupes, no watermelon, no muskmellon, no honeydew,... tried about 20 varieties, never a melon.
[18:02:40] <_methods> no melon zone
[18:02:41] <_methods> hehe
[18:02:47] <furrywolf> they either get grey mold, don't set fruit, or die before the fruit are more than marble-sized...
[18:03:10] <_methods> you need to play music for them
[18:03:12] <Crom_> We had 3 pumpkins, the biggest was 8"
[18:03:37] <PCW> We dont get enough heat for good melons but squash does really well
[18:03:39] <furrywolf> and that's both in the greenhouse and outside... they actually do slightly better outside, as the grey mold takes a little longer to hit...
[18:03:43] <Crom_> And lot of water
[18:04:49] <furrywolf> no, not lots of water. here you have to keep the top layer of soil dry. maybe lots of water, but delivered with drippers away from the stem.
[18:05:10] <furrywolf> if you let the plant or the top layer of soil get wet, the grey mold sets in.
[18:05:30] <Crom_> Love my summer squash, easier to buy the tasteless store bought squares
[18:05:37] <furrywolf> I'm not a squash fan...
[18:06:06] <Crom_> Wooo cnc pumkin carver
[18:06:12] <PCW> Yeah we live on squash through the summer months
[18:07:50] <Crom_> Y angular, x and z linear
[18:08:04] <furrywolf> https://gardenofyvonne.files.wordpress.com/2013/08/p1020285.jpg that type of grey mold. attacks melons here quickly...
[18:08:43] <_methods> the nano bots are training on your melons
[18:08:44] <SpeedEvil> The most effective tool to cure mold is a flamethower
[18:08:52] <_methods> soon they'll be coming for all of us
[18:09:33] <Crom_> Wife says watered down bleach for the mold
[18:10:50] <furrywolf> you can kill it, but the plant still dies... and so do all your other plants.
[18:10:54] <furrywolf> it's just too humid here.
[18:10:56] <Crom_> Slower oxidizer than flamethrower
[18:12:57] <furrywolf> now, in the greenhouse, peppers do reasonably well. outdoors it's a bit cool. only the manzanos produce well outdoors.
[18:14:01] <furrywolf> "We will Immediately leave you Positive Feedback within a few days." lol
[18:15:35] <furrywolf> I may or may not have a bunch of manzanos this year... I started some seeds last spring, but never got around to repotting them, so they've spent a full year in fertilizer-less rocky starting soil with no nutriants... they're about 10" tall, and close to pure white. but they are alive. I repotted them last week finally, will see if they turn green or not...
[18:15:59] <furrywolf> they don't like being in a little 6-pack tray for a year.
[18:16:58] <SpeedEvil> I have ~20 apple trees in various states of graft success I've got to repot this year
[18:17:15] <furrywolf> I haven't played with grafting... I've been tempted to try some pepper grafting.
[18:17:26] <SpeedEvil> Including some on 'well, I need to build a quadcopter anyway, so harvesting apples is a good excuse' rootstocks.
[18:17:36] <furrywolf> eh?
[18:17:47] <SpeedEvil> ~30 feet tall final tree
[18:18:08] <SpeedEvil> I'm going to be planting some of them in places I don't strictly own.
[18:18:19] <furrywolf> that's what a ladder and a fruit picker is for.
[18:18:21] <furrywolf> lol
[18:18:47] <furrywolf> I made one a while ago, worked great... just a basket and two prongs hose-clamped to a length of closet rod...
[18:19:10] <SpeedEvil> yeah. But at 25 feet, that stops working so well
[18:19:16] <furrywolf> that's what the ladder is for.
[18:19:52] <furrywolf> wow. apparantly people have grafted peppers and tomatos to the same plant.
[18:20:37] <SpeedEvil> Antirejection drugs for plants would be fun
[18:21:22] <furrywolf> all you need is a way to put cilantro and onions on it too, and you can have a salsa plant. :P
[18:23:58] <furrywolf> one study grafting peppers onto tomatoes got a 100% success rate out of 12 plants
[18:24:21] <furrywolf> whoops, 92 of 92 plants
[18:24:25] <furrywolf> that's pretty impressive
[18:25:22] <furrywolf> I am totally going to go pick up some tomato starts and try this.
[18:29:21] <furrywolf> bbl, need to run errands. (no, not picking up tomatoes - they won't have starts in for a bit)
[18:45:55] <Valen> ey archivist I got my surface finish better, lowered the tool to a squidgion below centerline seemed to do the trick
[18:49:12] <CaptHindsight> watermelon tree?
[19:11:12] <sliptonic> I'm looking at an old .ini file with units specified in the old format. "linear_units = 1.0", was that mm or in?
[19:29:16] <furrywolf> doing more reading... definitely going to try for pepper+tomato plants this year.
[19:35:35] <tjtr33> pcw_home, i saw the latency tests, thx, i must have a bad unit, >360uS with no isolcpus. 4glxgears and 1 mp3 from local SATA drive. same seller AFAIK
[19:36:48] <tjtr33> bthx, i'll try once more, reset bios to stock and try again
[19:36:50] <furrywolf> did you reset bios to factory defaults?
[19:36:51] <tjtr33> thx
[19:37:04] <furrywolf> bah, a second late... :P
[19:37:10] <tjtr33> yes i believe i tried it already, but will try agai again again
[19:38:31] <furrywolf> are you running off a real drive or off the usb thumbdrive?
[19:38:41] <furrywolf> (some boxes seem to go out to lunch reading usb)
[19:39:41] <tjtr33> sata WD 160G
[19:40:24] <furrywolf> ... on a completely and totally unrelated topic, I want http://www.wetforher.us/dildo-lesbian-sex-toys-all/34-strap-on-harness-dildo-multicolor-sex-toy-lesbian-.html (safe for work unless you look closely). Just because it looks so much like art that I could leave it out on the living room table and most people wouldn't notice it. lol
[19:40:34] <furrywolf> so a real drive.
[19:40:52] <furrywolf> 360us is... horrible.
[19:41:08] <furrywolf> I've never seen or heard of numbers that high.
[19:41:12] <tjtr33> i have it all logged at... https://www.dropbox.com/sh/n95e1h9qlj09cp2/AAA4g5Td3eGlicFJWh4cRWf4a?dl=0
[19:41:26] <tjtr33> and screen shots of some of the results
[19:42:05] <tjtr33> eh? weird post
[19:42:12] <tjtr33> ot ok
[19:43:10] <furrywolf> oh, so the sata drive is external?
[19:43:38] <tjtr33> internal
[19:43:50] <furrywolf> ah
[19:43:57] <tjtr33> i gonna go try it now, reset bios and run latency-histogram
[19:45:31] <furrywolf> somehow dropbox has broken... it loaded, all the thumbnails loaded, I viewed one image... now all the thumbnails are empty grey boxes and stay that way even reloading the page.
[19:46:08] <furrywolf> try turning off idle power saving
[19:47:45] <furrywolf> and try without the usb wifi adapter
[19:48:12] <furrywolf> I haven't had this problem with linuxcnc specifically, but I've had boxes that seriously went out to lunch when usb was involved
[19:48:32] <MacGalempsy> :) good evening
[19:53:08] <furrywolf> heyas
[20:07:00] <furrywolf> meh, I need more money. I want toys, a 7i76e, parts for my car,..
[20:08:24] <tjtr33> furrywolf, will try no usb wifi later, this is after 10 min http://ibin.co/1twz1ib5mOCK and latency histogram doesnt reveal maximums like latency-test does, so i dunno max
[20:10:50] <furrywolf> did you make sure idle power saving was off?
[20:12:15] <furrywolf> try the latency-test instead of the histogram... >20 isn't as useful as exactly how much over 20.
[20:14:01] <tjtr33> i will try the latency test after this cooks a while. i just re-looked at pcw's results, make s me wanna buy another unit ( not sellers fault , i suppose)
[20:14:35] <tjtr33> furrywolf, i didnt think pcw did anything at all to his syem, lemme re-read
[20:15:28] <tjtr33> i dont see he said anything about what he did , the screen says no isolcpus tho
[20:15:53] <tjtr33> whats all the unsymmetric stuff i get?
[20:17:08] <tjtr33> 8pm gotta go eat something, bbl
[20:25:11] <MacGalempsy> tjtr33: Thanks again for that schematic you sent over
[20:25:22] <tjtr33> np did it work?
[20:25:23] <MacGalempsy> I just wired up the first one and about to test it
[20:25:35] <tjtr33> (tomp ducks)
[20:25:50] <MacGalempsy> the first good news is the breaker didnt pop when I turned on the machine! lol
[20:28:23] <MacGalempsy> well dang
[20:30:33] <MacGalempsy> the voltage is correct, so now its just looking at the code again
[20:31:53] <tjtr33> red light = >18V? green light = <2?
[20:32:23] <tjtr33> (24V negative logic)
[20:32:49] <MacGalempsy> yeah. red is 19.6
[20:33:05] <MacGalempsy> green is ~1.0mV
[20:33:24] <tjtr33> now if you get the device to really turn on, you oughtta get green and <2V
[20:33:37] <tjtr33> me, i'm out for dinner, good luck!
[20:33:43] <MacGalempsy> thanks agian
[20:37:02] <Crom> Time to try out my pycam code
[20:37:58] <Crom> G16 is interesting
[20:39:44] <Crom> Easier for radiuses on common center points
[20:41:28] <Crom> Now I have to work out the math for making end point distances the same on different radiuses ala a hot plate
[22:07:19] * furrywolf wonders if mesa boards ever go on sale...
[22:42:25] <pcw_home> re: dc7800SFF, I just turned any obvious power saving options inthe BIOS (and set the fan about 1/2 way up)
[22:42:27] <pcw_home> Not only does it get decent RTAI latency, Preemt-RT latency (3.18.7-rt2) is good enough to run
[22:42:28] <pcw_home> Ethernet I/O cards at a 4 KHz servo thread sure you dont have a bad hard drive or something like that?
[22:42:30] <pcw_home> your plots are weird :-)
[22:42:38] <pcw_home> turned-off
[22:43:38] <Rab> pcw_home, I booted off USB thumbdrive and got significantly better numbers than from internal SATA. Can't figure that out.
[22:43:48] <Rab> But mine wasn't that bad either way.
[22:44:15] <_methods> 6gb/s sata headers or 3?
[22:44:31] <pcw_home> Im using a SSD, that may make a difference
[22:45:05] <Rab> I'm using a 320GB Seagate Barracuda, pretty old drive these days.
[22:45:45] <pcw_home> drive errors can cause latency problems
[22:46:04] <Rab> Hmm, I should check SMART info.
[22:47:20] <pcw_home> for Ethernet its significantly better than my (similar vintage ) desktop at home
[22:47:58] <pcw_home> maybe because of the PCIE intel 1G MAC on the MB
[22:48:43] <pcw_home> ping times are even better than my H97 MB with intel MAC
[22:49:26] <pcw_home> (in both cases you need to use ethtool and turn off IRQ coalescing)
[22:50:48] <Tom_itx> waiting for toys stuck in a snowdrift is a bitch
[22:50:57] <tjtr33> pcw_home, i'll try swapping hd, maybe run live cd, and set bios as you say, it just keeps climbing right now
[22:51:39] <pcw_home> Your plot is very strange

[22:52:02] <adoyle88> Hello everyone. As some of you know, in working on a CNC tubing bender. I've got a dumb question about hal and linuxcnc.
[22:52:16] <pcw_home> BTW that latest histogram has + and - peak values recorded
[22:52:50] <tjtr33> ah some new revision
[22:52:52] <tjtr33> my caxis showed up, damn heavy, they shipped a cast mounting plate and the Z bellows
[22:53:14] <tjtr33> adoyle88, ask the Q
[22:54:37] <adoyle88> I'm using an optical encoder to count degrees bent. I've successfully made an encoder that counts as pin 10 triggers. Now let's say I wanted to write some g code that tells the hydraulic valve to flip on until the encoder reaches 60 counts. How does my hal program intercept that command?
[22:55:10] <adoyle88> I'm setting up the bend axis as y and x as my feed.
[22:57:33] <adoyle88> so, as an example, I'm going to feed x 10 inches and then feed y 90 (degrees in my case). the y 90 command needs to turn on an output pin to trigger the hydraulic valve solenoid. as the rig bends, the encoder will count
[22:58:05] <adoyle88> then the output pin needs to be turned off when the encoder reaches 90
[23:30:50] <MacGalempsy> anyone making anything cool tonight?
[23:55:51] <MacGalempsy> dang internet went out
