[00:00:44] <XXCoder> nsa dont realize, no matter how secure it is, backdoor wont be nsa only
[00:08:10] <yasnak> of course
[00:08:21] <yasnak> anything static is so out of this world dumb
[00:08:27] <yasnak> dumb is an understatement
[00:08:46] <XXCoder> inmdeed
[02:55:53] <XXCoder> smoke some and watch https://www.youtube.com/watch?v=skD7r0yWOG4
[03:00:42] <yasnak> Editing my swiss machine post config files
[03:00:58] <yasnak> I know it must suck having to be a postconfig editor, but dang some of the logic blows my mind
[03:03:52] <XXCoder> man
[03:03:57] <XXCoder> that video is weird. lol
[03:17:10] <yasnak> adultswim after a long night at the bar is probably the best thing ever
[03:17:29] <yasnak> or whenever
[03:18:22] <XXCoder> I used to watch liquid tv
[03:18:31] <XXCoder> only small amount of adult swim
[03:19:07] <XXCoder> liquid tv is precursor to adult swim
[03:20:44] <yasnak> yeah
[03:20:50] <yasnak> check out robotchicken
[03:21:00] <XXCoder> loved its "in between" animation
[03:21:20] <yasnak> good shows. esspecially for those with nearly zero attention span like myself
[03:22:09] <XXCoder> heh I missed most of it
[03:22:17] <XXCoder> most wasnt captioned too
[03:22:40] <XXCoder> I remmber that show about fairly thin lady in furistic setting
[03:22:48] <XXCoder> it was fairly recently made into movie
[03:33:20] <Deejay> morning
[03:34:07] <felixi> AAAARARARARA. Cython seems like phun. Delays the need to actually need to know c++
[03:34:19] <felixi> who would want to code c++? :D
[03:34:35] <XXCoder> c++ is a messy beast on top of C
[03:34:40] <XXCoder> c++ compiles to C
[03:34:42] <felixi> i think alike
[03:34:44] <felixi> :D
[03:39:31] <Ralith> C++ doesn't compile to C any more than any native language does...
[03:39:57] <XXCoder> Ralith: it does. then it compiles C to normal binary
[03:40:18] <felixi> no no. it compiles to asm and then binary. doesnt it?
[03:40:24] <Ralith> XXCoder: no, that isn't even remotely how present-day compilers work
[03:40:37] <Ralith> I am a compiler engineer. This is my profession.
[03:40:48] <XXCoder> I'd say no, but then my knowledge may be behind
[03:41:07] <XXCoder> cool then
[03:41:15] <Ralith> your knowledge is two decades behind, or more :P
[03:41:22] <XXCoder> so it compiles direct now
[03:41:32] <XXCoder> I'd say 10+ years by now?
[03:42:00] <Ralith> compilation is a process of successive transformations, but C has not been involved in any major toolchain for quite some time
[03:42:22] <XXCoder> heh I only wrote one compiler, as part of college assignment
[03:42:30] <XXCoder> turtle script interpeter
[03:42:32] <Ralith> very few languges are so simple that you can actually go directly to machine code and C++ is certainly not one of them
[03:42:46] <felixi> i only read part of the dragon book for phun
[03:42:49] <felixi> :D
[03:43:17] <Ralith> (you might have been fuzzy on the implementation details but you're certainly right about it being a messy beast)
[03:43:22] <Ralith> (albeit a frequently useful one)
[03:43:45] <XXCoder> yeah I wrote ldraw to dxf converter on c++ at one point
[03:43:54] <XXCoder> earliest version was done in vb5 lol
[03:43:57] <Ralith> modern C++, most significantly as of the C++11 standard, has also changed quite a bit for the better
[03:44:04] <XXCoder> nice
[03:44:14] <felixi> Ralith: how?
[03:44:37] <Ralith> far less boilerplate and hazardous manual pointer juggling, richer ownership semantics
[03:44:57] <Ralith> richer constructs for compile-time computation
[03:45:37] <XXCoder> does it still using pointers?
[03:45:43] <XXCoder> sometimes such abuse is useful
[03:46:02] <Ralith> they're certainly available, but you're encouraged to avoid them where they're not specifically necessary
[03:46:34] <XXCoder> I remember making a union of a 64 bit int, so i could access it as 2 32 bit values, or 8 8 bit int lol
[03:46:43] <XXCoder> fun with unions
[03:46:52] <Ralith> that is not actually legal per the standard
[03:47:06] <Ralith> (well, it's legal, but the effects are undefined)
[03:47:52] <Ralith> in most environments you can get away with it but you're encouraged to implement such semantics with bit shifts and similar instead
[03:47:59] <felixi> is an ebook reader better for raeding books than a tablet?
[03:48:02] <XXCoder> hmm always thought union use was for that
[03:48:10] <XXCoder> felixi: WAAAAY better
[03:48:16] <Ralith> unions are for saving space, not for punning
[03:48:18] <felixi> XXCoder: you have exp? How?
[03:48:26] <Ralith> I concur, I'm very happy with my Kindle Paperwhite
[03:48:30] <felixi> XXCoder: i want a reader or a pad specifically for reading ebooks
[03:48:34] <XXCoder> felixi: its like reading paper so your eyes dont get too tired
[03:48:36] <felixi> i dont need or want pad otherwise really
[03:48:40] <Ralith> also, the batteries last absolutely forever
[03:48:47] <Ralith> and they're extra lightweight
[03:48:50] <XXCoder> I own kindle, and older NST and even older nook orginial
[03:49:00] <XXCoder> Ralith: it lasts 2 weeks for me lol
[03:49:04] <Ralith> well
[03:49:07] <XXCoder> I use em so heavily at work
[03:49:15] <Ralith> forever for a modern handheld computer, anyway :P
[03:49:19] <XXCoder> 6 hours read time everyday
[03:49:33] <XXCoder> sometimes less sometimes ricious amount more
[03:49:41] <felixi> which readers do you have? Are they easy to have bookmarks and browse back and forth
[03:49:45] <Ralith> my use is much more casual but I'm still a huge fan
[03:49:48] <felixi> like having papers between traditional books
[03:50:07] <Ralith> I just read fiction on mine, so I don't know; I wouldn't expect that to be particularly easy
[03:50:19] <Ralith> hm
[03:50:36] <Ralith> there are some features for hilighting passages and writing margin notes and stuff
[03:50:38] <XXCoder> good question as mine is mostly science fiction or fantasy
[03:50:39] <Ralith> might do what you want
[03:50:53] <XXCoder> fantasy isnt my forte but its hard to find book I havent read.
[03:51:07] <XXCoder> indeed
[03:51:13] <XXCoder> bookmarks, highlights, and notes.
[03:51:21] <Ralith> amazon's selling them pretty cheap these days, so it doesn't need a ton of agonizing over imo
[03:51:33] <XXCoder> or buy used nst or something, $40
[03:51:40] <XXCoder> see if you like ebook style display
[03:51:55] <XXCoder> but then kindle pw3 is around $120 if you want no ad version
[03:52:35] <archivist> cant beat read dead trees for reference books
[03:52:56] <Ralith> I actually favor PDFs on a laptop for reference books
[03:53:10] <XXCoder> archivist: yeah
[03:53:11] <archivist> needing to read circuit description and fold out diagram
[03:53:12] <Ralith> being able to search is amazing
[03:53:38] <Ralith> and have hyperlinked references, interactive table of contents trees, etc
[03:54:15] <archivist> here is a rare thing two zoomable views into one doc http://www.collection.archivist.info/diva/systrondonner1626.html#p=127&z=1
[03:54:21] <yasnak> I think its mainly because I do most my learning via toilet seat. My phone is a pain with PDF's
[03:54:24] <XXCoder> thats if pdf isnt just series of crappy pictures
[03:54:43] <archivist> bog reading++ the small library
[03:54:44] <Ralith> yeah, it is variable
[03:54:55] <Ralith> but a really good quality PDF is wonderful
[03:55:12] <felixi> http://www.pocketbook-int.com/us/products/pocketbook-color-lux
[03:55:14] <felixi> this one has colours
[03:55:23] <XXCoder> pdf is good standard if you want files to be useable for long time
[03:55:35] <XXCoder> but not if its badly done, like just batch of large pictures
[03:55:41] <Ralith> you probably do not want colors
[03:55:48] <XXCoder> you dont want colors indeed
[03:55:57] <felixi> its supposed to be e-ink or something
[03:56:00] <felixi> not lcd
[03:56:06] <XXCoder> HMM
[03:56:09] <Ralith> nonetheless it will cost more and have inferior contrast and resolution and software
[03:56:14] <XXCoder> thats new
[03:56:26] <Ralith> they've been around, they're just not a logical choice
[03:56:28] <XXCoder> I know of existance of "one color + grayscale" epaper
[03:56:42] <felixi> okw
[03:56:46] <felixi> hmm
[03:57:12] <felixi> http://www.bookeen.com/en/cybook-ocean
[03:57:15] <felixi> do you know this one?
[03:57:39] <Ralith> no, but it's more expensive than a paperwhite
[03:57:48] <felixi> paperwhite?
[03:57:57] <Ralith> amazon kindle paperwhite
[03:57:59] <XXCoder> kindle paperwhite 3
[03:58:03] <XXCoder> mines older 2
[03:58:10] <Ralith> I have the first
[03:58:13] <Ralith> very happy with it
[03:58:17] <felixi> mm
[03:58:24] <XXCoder> I'm happier now that I finally rooted it
[03:58:32] <XXCoder> custom screensavers is awesome
[03:58:39] <Ralith> amazon makes good quality hardware and has good software support
[03:58:49] <Ralith> I wouldn't buy from some no-name third party
[03:58:51] <felixi> paperwhite is also smaller
[03:58:55] <felixi> thats 8" display
[03:58:57] <XXCoder> https://www.youtube.com/watch?v=skD7r0yWOG4
[03:59:01] <felixi> id want 10" disp
[03:59:07] <Ralith> your call
[03:59:10] <felixi> =)
[03:59:13] <XXCoder> that looks like lcd
[03:59:22] <XXCoder> but then it isnt
[03:59:43] <Ralith> most likely just photoshopped advertising images
[03:59:53] <XXCoder> it isnt
[04:00:03] <XXCoder> it has standard refresh for epaper
[04:00:20] <Ralith> oh, you meant your video
[04:00:30] <XXCoder> heh yeah
[04:00:41] <XXCoder> colors is bit mute
[04:01:24] <XXCoder> https://www.youtube.com/watch?v=k57kddYCPrU
[04:01:30] <XXCoder> shaky camera but closer loojk
[04:01:56] <XXCoder> dang that looks like looking at real cartoon
[04:02:32] <XXCoder> http://goodereader.com/blog/electronic-readers/review-of-the-pocketbook-color-lux-ereader
[04:03:13] <XXCoder> Ralith: youre right, it is slow, one bad aspect. and jeez just 256 mb ram
[04:04:05] <Ralith> considering the demands of text, why go for experimental color tech over robust grayscale?
[04:04:24] <XXCoder> from what I understand, display is great
[04:04:34] <XXCoder> bogged by crappy hardware on backend
[04:05:38] <XXCoder> honestly pw works fine for me lol
[04:07:16] <XXCoder> felix apparently left
[04:07:20] <XXCoder> too bad because "You would figure a full color touchscreen e-reader would excel reading technical documents or other manuals. Surprisingly this fails in almost all regards"
[04:07:28] <XXCoder> and guy wanted to do exactly that
[04:08:28] <XXCoder> "The Color Lux is simply unusable in its current form and should be avoided at all costs."
[04:08:30] <XXCoder> too bad
[04:09:50] <Ralith> weird
[04:10:11] <XXCoder> they skimped too much
[04:10:17] <Ralith> maybe a competent screen manufacturer parnered with an inept everything-else manufacturer
[04:10:36] <XXCoder> yeah
[04:10:42] <XXCoder> it cant be bought on amazon
[04:11:30] <XXCoder> nor ebay
[04:12:48] <XXCoder> they might have recalled all or something
[04:13:04] <Ralith> or they're just that obscure
[04:13:30] <XXCoder> "Pocketbook has not offered an explanation for why they took this ereader off the market but I can add that they removed it in less time than they took to release it."
[04:13:38] <Ralith> huh.
[04:13:45] <Ralith> funny
[04:13:55] <XXCoder> released in 2013
[04:16:02] <XXCoder> I found current one
[04:16:08] <XXCoder> ectaco jetbook color 2
[04:16:12] <XXCoder> its $500
[04:17:49] <XXCoder> funny
[04:17:59] <XXCoder> outside usa there is so many ebook devices
[04:18:07] <XXCoder> in usa we have kindle... and nook.
[04:20:35] <XXCoder> I still want epaper montior lol
[04:41:03] <yasnak> I need a fourth monitor
[04:42:07] <XXCoder> to display what?
[04:42:46] <yasnak> idk, I am so used to using three. one for cad, one for cam and one for program editing. if I had a fourth I could still surf haha.
[04:43:02] <XXCoder> lol
[04:43:19] <yasnak> But no, one that would be setup the long way. for ebooks/documention/reading
[04:43:55] <XXCoder> 10 montior setup ;)
[04:44:11] <XXCoder> with CAD main screen being 60" tv
[04:45:03] <yasnak> you have?
[04:45:12] <yasnak> wtf do you drive that with?
[04:45:28] <XXCoder> lol no that was recommandation for you
[04:45:31] <yasnak> ohhhh
[04:45:32] <XXCoder> well jokey one but yeah
[04:45:56] <XXCoder> myself I just use dual screen
[04:46:04] <XXCoder> second one is basically for irc
[04:46:06] <yasnak> yeah, i've got three 27's and two laptops on my desk haha
[04:48:22] <XXCoder> lol ok
[05:06:05] <Loetmichel2> *FINALLY* my wife sits in her car on her 600km journey to praha. $me had to pack her suitcase. and bring it to the car. and get it back in, wrong suitcase, pack the bigger one please... for 3 hours straight now. MAN she is only on a 5 day business trp? why does she need clothes for a month?
[05:07:06] <Loetmichel2> ... and why am I the idiot to have to pack that stuff for her? (ah, yes, samre reason why i have to pack the Wheelchair into her car: she has a bad hip and cant lift the heavy stuff on crutches)
[06:37:25] <eventor> had there been changes in the gladevcp part from 2.6 to 2.7? I updated my machine, everything works, only in the glade panel the Led's / Boxes shows no value. In the Terminal window is no error/message shown.
[07:16:29] <yasnak> eh, one thing somewhat started. yes i know, this setup blows. :/ http://imgur.com/dUnGpYR
[07:23:58] <_methods> 835 hours later
[07:28:38] <yasnak> actually...0.622ipm
[07:29:04] <yasnak> need to make 30 parts, profiles are too much for running on the swiss at this quanity
[07:58:18] <Tom_itx> morning
[08:04:18] <JT-Shop> morning
[08:05:53] <_methods> butt roast on the smoker
[08:10:00] <jthornton> rufus making me a bootable thumb drive
[08:11:15] <Jymmmm> <Rufus here> Make it yourself!
[08:12:21] <skunkworks> of what?
[08:12:38] <jthornton> freedos
[08:12:51] <Loetmichel> thats "sduo make me a bootable thumbdrive" ;)
[08:12:57] <Loetmichel> sudo
[08:13:22] <skunkworks> for some of our old plc software I made up a bootable dos usb drive.
[08:13:30] <skunkworks> worked great
[08:15:05] <jthornton> I've got a opto22 card on the way, do you just plug it in and use gpio?
[08:21:28] <yasnak> If my boss doesn't come in by 10AM i'm grabbing the 6 pack from my truck
[08:21:48] <yasnak> The decision has been made
[09:08:44] <os1r1s> How tight should the gibs on the Y axis of a G0704 be?
[09:11:06] <archivist> the right much, no slop, free to move
[09:11:10] <_methods> you don't want the gibs so tight they impede movement
[09:11:54] <archivist> check end to end for binding
[09:12:30] <_methods> it's usually a PITA tweaking in gibs on cheap machines
[09:12:44] <os1r1s> If you can't push it by hand, but can turn a handle to make it move ( on a manual mill), is that ok?
[09:12:55] <Tom_itx> yeah all that extra scraping etc to get them right...
[09:13:50] <_methods> you shouldn't be able to move the axis by hand
[09:14:21] <os1r1s> _methods Well then that is excellent news.
[09:14:37] <_methods> not really
[09:15:44] <_methods> you should have to turn the handles to move the axis
[09:16:04] <_methods> except maybe your z axis if the counterbalance is removed
[09:17:52] <archivist> stiction until the oil film builds up then the slide a lot easier
[09:42:36] <newbie25174> hello
[09:42:49] <zeeshan|2> hi
[09:43:52] <newbie25174> I'm looking for a drill bit
[09:45:23] <yasnak> uh
[09:45:31] <yasnak> not sure drill bit is online, might be sleeping yet
[09:46:37] <newbie25174> I have 1/8" ZrO2 sphere that I need to drill about half the depth
[09:47:18] <newbie25174> what kind of a drill bit can handle that
[09:47:35] <archivist> grind
[09:47:38] <yasnak> Okay, so you're going to drill an 1/8 piece of it? I don't understand
[09:48:00] <zeeshan|2> daimond
[09:48:02] <zeeshan|2> diamond
[09:48:33] <newbie25174> and where I can get very small dimond drill bit...
[09:48:45] <archivist> burr
[09:49:15] <archivist> you can also use a diamond paste and copper
[09:49:52] <newbie25174> what is dimond paste?
[09:50:23] <archivist> powdered diamond dust in a lubricant
[09:50:45] <yasnak> harveytool.com
[09:50:55] <yasnak> but it won't be cheap
[09:51:49] <yasnak> I'd just use a POS carbide burr and see what happens. I've never cut ZrO2. The fact you think you can drill it makes me think you can at least burr it.
[09:52:28] <newbie25174> I want to make a tip for my probe.
[09:52:30] <archivist> read Geroge Daniels watchmaking book section on jewel drilling
[09:52:45] <archivist> george
[09:53:06] <yasnak> lol
[09:53:11] <yasnak> Why not just buy a tip man?
[09:53:18] <yasnak> It'll cost less then the tool/time needed
[09:53:52] <archivist> plenty cheap stylus on ebay
[09:55:49] <pink_vampire> back to the normal PC
[09:56:37] <pink_vampire> It's me with the Zro2
[09:57:36] <Sync_> yeah paste and copper probably works the best
[09:58:20] <Erant> I have a weird problem. My Z-axis has a little backlash that's variable with speed. Or more likely, acceleration. Higher speed, less backlash.
[09:58:47] <Erant> Difference of about 1.5 thou between moving the head @2.2IPM vs @20IPM
[09:59:14] <Erant> The only thing I can think of is some stiction issue, and the stronger jerk is overcoming it faster
[09:59:31] <_methods> yeah
[09:59:44] <pink_vampire> something like that? http://www.tptools.com/Meguiars-Diamond-Cut-Compound,1730.html?ns_md=CSE&ns_sc=GoogleProducts&ns_cn=GoogleProducts&utm_medium=CSE&utm_source=GoogleProducts&utm_campaign=MG-8532&gclid=CNnThpPkmssCFcJahgodWfsODA
[10:00:04] <pink_vampire> archivist: ^
[10:00:07] <Erant> _methods: I sort of figured. I might replace the gib with a brass one, see if that works better.
[10:00:26] <Erant> Or just take the current steel one out and polish it a little
[10:00:53] <archivist> pink_vampire, no
[10:01:04] <pink_vampire> :(
[10:01:24] <pink_vampire> archivist: do you know the brand name for it?
[10:01:26] <archivist> Erant, dont think brass is a normal cure
[10:02:39] <Erant> Huh. I'd always hear brass or delrin
[10:02:52] <Sync_> just scrape your current one
[10:02:55] <archivist> https://www.cousinsuk.com/category/abrasive-pastes
[10:03:14] <Sync_> or just use a ball bearing pink_vampire, they can be drilled with carbide with ease
[10:03:18] <yasnak> get some of the cylinder grinding compound from autozone
[10:03:23] <yasnak> works great and is cheap
[10:04:33] <Sync_> I'm not sure if it is hard enough for ZrO2
[10:05:24] <pink_vampire> archivist: I can't see anything about diamond, It's just say abrasive compound.
[10:05:25] <zeeshan|2> sync
[10:05:28] <zeeshan|2> have you used this before: http://www.waytekwire.com/item/20418/Black-Self-Closing-SAE-Braided/
[10:06:15] <archivist> https://www.cousinsuk.com/product/diamond-paste-af-swiss
[10:08:16] <Sync_> zeeshan|2: I always used the regular kind
[10:08:21] <Sync_> but I heard it works nice
[10:08:29] <zeeshan|2> id like to try it
[10:08:37] <zeeshan|2> it looks more flexible than the corrugated stuff
[10:08:44] <zeeshan|2> which sucks cause i have aLOT of that corrugated stuff
[10:09:23] <JT-Shop> just lacking a battery, switch, and solenoid to having an electric start splitter!
[10:10:11] <pink_vampire> archivist: there is several grits, or and grit will work just fine?
[10:11:36] <Sync_> http://ecx.images-amazon.com/images/I/31J3D2lsm1L.jpg zeeshan|2 that shit
[10:12:08] <Sync_> well the rougher the faster it will cut, but it is an optimization problem
[10:22:27] <HoloPed_> hey all. Is there a non-shitty software for doing vector-to-gcode for homebrew laser cutters ?
[10:24:21] <MrSunshine_> oh you all are back! :P
[10:24:28] <MrSunshine_> i was alone there for a long while =)
[10:25:08] <MrSunshine_> noticed i got a bit of twist in the router table ... i wonder how to correct that =)
[10:25:15] <MrSunshine_> got Xes on every side .. welded =)
[10:25:35] <MrSunshine_> (im heat straightening the machine right now ... going quite well so far =) )
[10:32:42] <enleth> any suggestions for a relay/ladder logic/machine wiring schematic editor?
[10:33:33] <enleth> I'm rewiring the power relays in the bridgeport to hook the VFD into the relay logic properly and the factory schematic is going to go out of sync with reality
[10:34:03] <enleth> I can annotate some small changes with a pencil, but there are limits to this method
[10:34:52] <PetefromTn_> is this a linuxCNC retrofit?
[10:35:46] <enleth> yes, but I'm keeping most of the original relay logic
[10:35:55] <PetefromTn_> ah okay
[10:36:56] <enleth> the safety circuits are really well done and I'm going to trust them much more than any software
[10:37:32] <enleth> especially when it comes to cutting servo power on limit switches
[10:37:48] <enleth> and engaging brakes at the same time
[10:38:13] <PetefromTn_> when it comes to power on and off I agree
[10:38:21] <PetefromTn_> my machine is setup similarly
[10:41:59] <enleth> basically there is a chain of limit switches, overload switches and thermostats in various places that have to agree for the main feed contactor to remain closed
[10:42:21] <Jymmmm> Your machine shuld be in a crate and on a trailer goin to florida!
[10:42:39] <enleth> that in turn controls the brake relays
[10:42:56] <enleth> *and* feeds power to the servo drive
[10:43:41] <enleth> I'm not changing that, but I am rewiring the contactors that powered the spindle motor, so that they instead signal the VFD to run
[10:44:25] <enleth> *and* pass the VFD's "motor running" signal to the logic that controls VariSpeed
[10:46:10] <enleth> I can rewire it just fine and probably remember most of that for a few weeks
[10:47:10] <enleth> but I fear I'll start forgetting the details in a few months and problems will crop up when I start using the original schematic
[10:47:26] <duc> Notebook or PowerPoint can be used in a pinch
[10:47:32] <PetefromTn_> yup mine is setup the same way, limits, estop, etc are trips for main power contactors for the drives and spindle motor... And it is getting packed up this coming week.. for its trip to florida
[10:48:06] <PetefromTn_> I made a schematic diagram in draftsight showing the whole wiring scheme...
[10:48:44] <PetefromTn_> it is kind of a block diagram with small blow up circles with specifics inside them for wiring
[10:49:02] <PetefromTn_> the same scheme is getting used on the CNC lathe
[10:49:16] <tiwake> morning
[10:50:19] <PetefromTn_> http://imgur.com/BwSLrdw :D
[10:52:22] <tiwake> well
[10:52:40] <tiwake> my black shoe leather dye sucks for some reason
[10:53:28] <Jymmmm> tiwake: Just use spray paint ;)
[10:53:42] <tiwake> for anodizing? heh
[10:53:49] <Jymmmm> lol
[10:54:22] <Jymmm> why would you use ax based for annodizing?
[10:54:25] <Jymmm> wax*
[10:54:42] <Jymmm> wax/grease
[10:54:56] <tiwake> actually its labeled leather dye
[10:55:08] <tiwake> I don't think it says anything about shoes
[10:56:24] <Jymmm> Fine, use a sharpie marker then =)
[10:57:21] <tiwake> did some anodizing last night and the parts when dyed with the leather dye came out splotchy
[10:57:48] <tiwake> put the others in the casswell black dye (water based) and it was fine
[10:58:16] <Jymmm> Did you use anti-splotchy leather dye?
[10:58:23] <enleth> PetefromTn_: do you have the schematic screenshot online?
[11:01:23] <tiwake> this is the dye I used http://www.amazon.com/Fiebings-Leather-Dye-Black-4oz/dp/B000HHM20M/ref=sr_1_1
[11:08:28] <DRGray> i realy struggled with anodising
[11:08:54] <DRGray> is that leather dye good?
[11:09:55] <DRGray> i think i have some caswell die but ive strugged to get good results
[11:11:24] <tiwake> DRGray: donno, I do know I anodize longer than suggested and I'm getting really good colors
[11:11:36] <Jymmm> tiwake: NFC, but... http://www.usspecialty.com/product.php
[11:11:50] <DRGray> with the casswell or the leather dye?
[11:12:01] <tiwake> DRGray: casswell dye
[11:12:08] <DRGray> yeah
[11:12:21] <DRGray> do you use much dye? does it go a long way?
[11:13:00] <tiwake> I have some dye coming from where CaptHindsight works... but not black because they are dumb and don't have black
[11:13:17] <Jymmm> tiwake: http://www.usspecialty.com/color.php
[11:13:26] <tiwake> Jymmm: I see :P
[11:14:00] <tiwake> Jymmm: are those solvent based or water based?
[11:14:02] <DRGray> 120ml = £47 doesnt seem like a lot of dye for the money
[11:14:24] <Jymmm> tiwake: 2016-02-28.08:46:13 Jymmm: tiwake: NFC, but... http://www.usspecialty.com/product.php
[11:14:42] <rob_h> they are clariant dyes, water they sell very very good
[11:14:51] <Jymmm> tiwake: NFC = No Fucking Clue ;)
[11:15:00] <tiwake> oh
[11:15:56] <tiwake> Jymmm: looks like its water based
[11:15:58] <tiwake> meh
[11:16:06] <tiwake> I kind of want solvent based :P
[11:16:17] <rob_h> y?
[11:16:25] <tiwake> cause I'm lazy and don't want to heat up the water bath
[11:16:33] <rob_h> i see
[11:17:01] <rob_h> iv had a clariant black dye bath setup for last 4 years never had a problem with it.. only had to keep it in balance
[11:17:39] <tiwake> rob_h: do you have to heat up the dye bath?
[11:18:03] <rob_h> yes
[11:18:09] <rob_h> 50c
[11:18:15] <tiwake> what happens when you don't?
[11:18:27] <rob_h> dye does not take to the poores so well
[11:18:33] <rob_h> and colours wount be as rich
[11:18:37] <tiwake> yeah
[11:18:58] <tiwake> for some reason my casswell purple and blue stick to the parts really really well and don't need heating
[11:19:05] <rob_h> need air aggregation too keeps it well mixed
[11:19:37] <rob_h> black is probly the worst colour to keep deep and rich black... and more fussy on poor size
[11:19:52] <rob_h> pore
[11:20:07] <tiwake> thats what I've heard
[11:20:27] <rob_h> i run 12 ASF tho
[11:20:38] <tiwake> ASF?
[11:20:52] <rob_h> amps per squarefoot
[11:21:07] <Jymmm> @ 440V
[11:21:23] <rob_h> anodizing tends ot be around 15/16v
[11:21:28] <tiwake> been running about 4ish amps
[11:21:34] <rob_h> depends on racks etc.. if Ti racks need add volt
[11:21:56] <rob_h> but i never anodizing to volts only CC
[11:21:57] <tiwake> with voltage typically popping out at 12-14
[11:22:33] <rob_h> i found power supplies make a big differance too if they are not real CC things get hard fast
[11:22:55] <tiwake> yeah, I have a good constant current power supply :3
[11:23:08] <tiwake> rob_h: have any suggestions for racks?
[11:23:16] <rob_h> i use 90% of time Ti
[11:23:23] <rob_h> i got fedup stripping realy fast
[11:23:31] <tiwake> yeah
[11:23:38] <rob_h> i have somealli jigs but use very rare... for spehsial parts that dont fit Ti
[11:23:54] <rob_h> or i use Alli wire 1.5mm/2mm welding wire works realy well
[11:24:11] <rob_h> and just cut it off part when done etc
[11:24:28] <tiwake> thats what I'm running into, using aluminum (electrical fence) wire to hang parts in
[11:24:36] <tiwake> pain in the butt
[11:24:39] <rob_h> if in US your lucky these guys have good prices i found for racks.. and in stock. http://www.anodizingracksonline.com
[11:25:16] <tiwake> I also need to get an acid pump to keep the liquid moving
[11:26:16] <rob_h> just run a good air aggregation pipe in acid tank stop part burning and keep it moving id not pump it around gets messy
[11:27:13] <rob_h> i would only pump for cooling if indirect cooling
[11:27:35] <tiwake> but air would make the acid kind of splatter everywhere
[11:28:21] <rob_h> dont need much air lo
[11:28:38] <rob_h> and use a fume suppressant ;)
[11:29:02] <tiwake> those are good prices for rack stuffs
[11:29:05] <tiwake> shiny
[11:29:12] <tiwake> rob_h: I love you
[11:29:51] <rob_h> i just got a 4th rack other week from them
[11:30:03] <rob_h> as my tanks are not that deep i cut them in half :)
[11:30:14] <tiwake> yeah
[11:30:31] <skunkworks> JT-Shop: yes
[11:30:33] <tiwake> I just bought a 40gallon water troth from my local feed store
[11:30:41] <skunkworks> You may have to figure out power for it.
[11:30:45] <tiwake> probably going to fill it up on monday
[11:31:42] <rob_h> then you will want bigger
[11:32:50] <tiwake> rob_h: how do you check to make sure your acid bath keeps the correct amount of acid/water?
[11:33:01] <rob_h> its only water than evaps
[11:33:03] <rob_h> that
[11:33:17] <tiwake> mostly, but not quite
[11:33:19] <rob_h> over a very long time yes u will get drag out
[11:33:26] <tiwake> some acid leaves when you pull the parts out
[11:33:42] <tiwake> heh, not much, but it does a little
[11:33:45] <rob_h> but i do a quick Titration every now and then
[11:34:18] <DRGray> what do you use to connect to the parts that doesnt disintegrate and carries the current well?
[11:34:26] <rob_h> some try and measure the specific gravity but does not work due to the alli in bath
[11:34:46] <Erant> What setting do I need to change to fix the stepgen 'joint following error' thingy? I've already set the stepgen velocity to be 25% higher than max_velocity, but at higher speeds (+60IPM), I still get the following error.
[11:35:12] <rob_h> i got some Alli bar stock and connected to it with power lines.. and from that i have tend to use flying leads with some croc clips to connect to the jig/part
[11:35:29] <rob_h> then replace them every now and then as do get abit attacked
[11:35:37] <tiwake> ..?
[11:35:52] <tiwake> flying leads?
[11:35:59] <rob_h> abit of wire
[11:36:24] <tiwake> I wouldent mind some pictures if you have them XD
[11:36:26] <Jymmm> Erant: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error
[11:37:04] <Jymmm> Erant: lower your base period ???
[11:37:15] <rob_h> on steppers dont you feed command back to acctal ? i dont know i never done stepper system
[11:37:36] <rob_h> unless stepper with encoder
[11:38:18] <tiwake> rob_h: also I'm finding that I want to anodize wheel rims and various other things around the house now
[11:38:35] <rob_h> rims like car rims
[11:38:39] <tiwake> yeah
[11:38:49] <rob_h> you might find most have a very high content of MAG
[11:38:54] <Jymmm> tiwake: annodize the washer and dryer and frig and freezer and sinks and toilets, yeah the toilets!!!
[11:38:58] <rob_h> and cast form so will not anodizing well at all
[11:39:09] <tiwake> did my pocket knife handle a while ago
[11:39:25] <DRGray> my croc clips disintegrate
[11:39:47] <tiwake> rob_h: yeah, I'd imagine that cast aluminum won't anodize very well
[11:39:57] <rob_h> most not at all
[11:40:12] <rob_h> thoes that do have to mess around with them and pre etch/ and other nasty things
[11:40:32] <DRGray> yeah
[11:40:35] <tiwake> aluminum wheel rims are turned though arnt they? I suppose they might be forged...
[11:40:36] <rob_h> prob getting into using nitric acid then too and id not go there
[11:40:45] <DRGray> i need to have a bit more of a play
[11:40:53] <DRGray> i have a shed with some nasty acid in it
[11:41:30] <SpeedEvil> I have a barrel of 94% h2so4
[11:41:37] <tiwake> yeah, don't keep nitric acid in the same building as the machines are in
[11:42:03] <DRGray> i have some cant remember how strong it is
[11:42:15] <DRGray> i also have some hydrocloric
[11:42:23] <DRGray> that burns the nostrils
[11:42:28] <tiwake> alligator clips... is that what you use for some parts?
[11:42:49] <DRGray> i have tried that
[11:42:55] <tiwake> I mean
[11:43:14] <tiwake> clips would be nice of some sort, but most have iron in them don't they?
[11:43:16] <DRGray> i havent tried in a while but i need to get the hang of ti
[11:43:19] <DRGray> yeah
[11:43:21] <DRGray> thats the issue
[11:43:26] <DRGray> they just get vapourise
[11:43:27] <DRGray> d
[11:43:37] <DRGray> but you need something that conducts
[11:43:43] <DRGray> im not that experienced at it
[11:43:55] <tiwake> likewise... heh
[11:44:04] <DRGray> my dads a retired chemist i should quiz him
[11:44:12] <tiwake> oh pff
[11:44:14] <rob_h> croc clips yes... find some that are nickel plated last longer then.. and not cheap ones that plating falls off when you use
[11:44:16] <DRGray> he used to do it all the time at work
[11:44:26] <tiwake> I would drain all the information out of my dad if he was like that
[11:45:03] <rob_h> there is or was a yahoo group for anodizing alot of info there
[11:45:10] <tiwake> rob_h: well, I know a plater... he does most of the copper connectors I make
[11:45:49] <DRGray> i think you need good dyes as well something with really small particles
[11:46:01] <tiwake> yeah
[11:46:04] <DRGray> and improve my patience
[11:46:21] <tiwake> solvent based dye is really nice for that
[11:46:29] <rob_h> keep acid at good temp too to keep constant pore size if colours is important to you
[11:46:30] <tiwake> it "just sticks in"
[11:47:38] <tiwake> http://bucktownpolymers.com/anodize00.html
[11:48:23] <DRGray> what is a good tempreture?
[11:48:49] <tiwake> *shrug* probably consistent temp most likely
[11:48:55] <DRGray> i need somehwere in the uk
[11:48:58] <DRGray> ys
[11:48:59] <DRGray> yes
[11:49:11] <rob_h> around 17c
[11:49:13] <tiwake> my shop stays pretty consistent summer and winter
[11:49:29] <DRGray> keep it somehwere constant
[11:49:33] <rob_h> whats that 62f for the US guys
[11:49:46] <DRGray> 17c is sort of workshop room tempreture
[11:49:50] <rob_h> too cold and pore are too small
[11:49:59] <rob_h> too hot and pore too big and part burn is easyer
[11:50:21] <tiwake> that happened to me once
[11:50:58] <tiwake> anodized too long and the part looked like it was dried up, like a raisin
[11:51:00] <DRGray> il give it another go this week i need to get it set up again, where i’ve been doing it sounds to cold its an outside shed.
[11:51:28] <tiwake> I think if you lower your current density that it will increase your pore size too
[11:51:47] <rob_h> just take longer
[11:51:57] <rob_h> but less heat made
[11:52:03] <tiwake> maybe 2-3 amps/ft^2
[11:52:10] <rob_h> why casewell do 7asf i think it is and not the common 12
[11:52:22] <tiwake> I run at 4-5 amps/ft^2
[11:52:26] <DRGray> rob_h: what dye do you use for black?
[11:52:35] <DRGray> what voltage?
[11:52:53] <tiwake> DRGray: constant current, so whatever the voltage pops out at
[11:53:03] <rob_h> clariant dyes for all
[11:53:12] <DRGray> what sort of power supply do you use?
[11:53:21] <tiwake> a bench power supply
[11:53:21] <rob_h> its a CC 3phase in
[11:53:28] <rob_h> 24v max out 500amp
[11:53:33] <tiwake> woah
[11:53:38] <tiwake> thats a serious power supply
[11:53:39] <tiwake> lol
[11:53:46] <tiwake> three phase
[11:53:47] <tiwake> ha
[11:53:47] <rob_h> well babby compared to a plating shop
[11:53:56] <rob_h> yea 3phase at home is nice as well as at work i guess
[11:54:26] <rob_h> iv used bench before but some not work grate others work very well
[11:54:50] <tiwake> I just have a 50amp max, 15-16 volt max bench power supply, I think it cost about $200
[11:54:51] <rob_h> i did or still do have two old ex mill bench power supplies 40amp out, 40v out
[11:55:22] <rob_h> but they have a fault and i think its output transister stack i go tthe parts but never had time to fix.
[11:55:56] <tiwake> if it goes above 15amps it switches over to constant voltage
[11:55:58] <DRGray> i have a desk top psu variable but i think it onyly does about 3 amps
[11:55:59] <tiwake> erm
[11:56:04] <DRGray> bit rubbish i guess
[11:56:06] <tiwake> above 15 volts rather
[11:56:20] <rob_h> depends what you doing
[11:56:30] <rob_h> not very CNC this chat lol
[11:56:30] <DRGray> i have 24-40 volt one, but it has some sort of protector in it
[11:56:34] <tiwake> DRGray: you need something that does constant current
[11:56:38] <DRGray> so it cuts out if you try and use it for anodising
[11:57:07] <rob_h> i think we all need to go make some parts to think about anodizing now
[11:57:27] <DRGray> parts that get made need colouring :-)
[11:57:40] <rob_h> indeed
[11:57:49] <rob_h> i notice the UK spelling ;)
[11:57:50] <tiwake> hmm
[11:58:09] <tiwake> I want an all aluminum car now and an anodizing tank big enough to hold it
[11:58:33] <archivist> landrover
[11:58:51] <DRGray> http://www.ebay.co.uk/itm/375W-Linear-DC-Variable-Voltage-Bench-Power-Supply-Adjustable-3V-15V-Brown-Box-/371560379360?hash=item5682b973e0:g:L6oAAOSwKtVWzIbS
[11:58:54] <DRGray> what do you reckon?
[11:59:11] <DRGray> ah you have noticed the ukish in me
[11:59:22] <rob_h> erm depends what asf you want to use
[11:59:25] <DRGray> http://www.ebay.co.uk/itm/HEAVY-DUTY-BENCH-VARIABLE-OUTPUT-POWER-SUPPLY-0-40V-0-50A-THORN-AUTOMATION-/121870581451?hash=item1c600d7ecb:g:eooAAOSwKtlWn3fa
[11:59:32] <rob_h> as 15v out will limit you
[11:59:42] <tiwake> yeah
[11:59:45] <rob_h> i got 2 of them want fixing
[12:00:01] <rob_h> im UK so you can pickup ;)
[12:00:02] <tiwake> 15 volt max is about 4 amps/ft^2 or so
[12:00:07] <rob_h> but yes they work grate
[12:00:30] <DRGray> hah what part
[12:00:31] <DRGray> ?
[12:00:35] <DRGray> im over in wales
[12:00:52] <tiwake> alright, I'm taking off
[12:00:52] <rob_h> well they turn on but do not output why i think its just the transisstors gone bad
[12:00:59] <tiwake> cheers, thanks for the chat :D
[12:01:18] <rob_h> i am Cambridgeshire so all the other way
[12:01:32] <rob_h> bye tiwake
[12:02:11] <DRGray> hah yeah a bit far
[12:02:39] <rob_h> always come see all the linuxcnc machines running as well as non linuxcnc
[12:02:49] <DRGray> 30v 5 amp to low?
[12:03:13] <archivist> amps depends on area to be anodised
[12:03:30] <rob_h> take your biggest part you want anodizing work out amps
[12:03:34] <rob_h> add abit of head room
[12:04:02] <rob_h> most power supplies dont like working maxed out for long times tend to over heat
[12:05:15] <DRGray> http://www.shadowguarddev.com/alex/anodizing/
[12:05:22] <DRGray> Many people use automotive battery chargers to anodize;
[12:05:26] <DRGray> i have plenty of these
[12:05:54] <rob_h> just have control the output
[12:06:56] <DRGray> a big varialbe resistor?
[12:10:36] <Jymmm> a trough of moist salt?
[12:29:33] <CaptHindsight> DRGray: you need particles much smaller than the pores, so <20nm
[12:29:50] <CaptHindsight> thats why dyes are used vs pigments
[12:30:08] <CaptHindsight> dyes are in solution, particles are in suspension
[12:31:04] <CaptHindsight> you can use particles or pigments but they need to be milled down to <20nm for aluminum
[12:32:15] <DRGray> yeah
[12:32:27] <DRGray> i did buy some die for aluminium
[12:32:35] <CaptHindsight> tiwake: you don't need to dip an entire car to color it, the dye can be applied by spray
[12:32:37] <DRGray> but wasning getting consistant results
[12:33:11] <CaptHindsight> DRGray: thats where solvent dye comes in, it doesn't wash out when rinsed
[12:33:21] <CaptHindsight> or when sealed
[12:33:58] <DRGray> any ones you recommend?
[12:34:45] <CaptHindsight> thats how images, graphics, text etc are done in anodize
[12:35:11] <CaptHindsight> airbrush, stencil, silkscreen, inkjet etc
[12:35:20] <DRGray> ah
[12:35:29] <CaptHindsight> http://bucktownpolymers.com/anodize00.html
[12:35:44] <DRGray> yeah not sure how to get hold of thiers in the uk
[12:36:31] <DRGray> they want to charge 100$ for shipping
[12:36:52] <CaptHindsight> flat rates based on USPS boxes
[12:37:17] <DRGray> yeah probably includes import taxes
[12:37:38] <DRGray> i need to try and find a uk source
[12:37:41] <DRGray> probably isnt one
[12:37:49] <CaptHindsight> or buy in bulk
[12:38:32] <CaptHindsight> it's apples and oranges for water vs solvent dye
[12:39:08] <archivist> uk http://gaterosplating.co.uk/Anodising-Dyes.php
[12:39:16] <CaptHindsight> the solvent dye is premixed and the only waste is what you might spill
[12:39:36] <CaptHindsight> or if you blend to much custom color and then not use it
[12:39:56] <DRGray> this is where i got my black dye from
[12:40:04] <CaptHindsight> water based you mix yourself and you have to tweak the bath
[12:40:29] <DRGray> yeah
[12:40:30] <archivist> the phone number is in my area!
[12:40:38] <DRGray> tweak ?
[12:41:16] <CaptHindsight> the big difference is when you require color that last more than a few years in direct sunlight
[12:41:42] <CaptHindsight> dye is easily broken down by UV
[12:42:10] <DRGray> yeah non of my stuff goes in the sun
[12:42:17] <CaptHindsight> so you need colorants that fit in the pores and don't easily break down when exposed to UV
[12:43:26] <CaptHindsight> there are also other things you can trap in the anodize like lubricants
[12:43:33] <DRGray> ill try again this week and be more methodical and patient see if i can get a some better results
[12:49:44] <DRGray> ok.. back to some cnc topics. on a stepper motor is a there a good guide pro/cons of not direct driving your stepper and putting it on a belt?
[12:50:30] <DRGray> also whats the best linux cad program?
[12:51:40] <Jymmm> DRGray: The one you create is the best of them all!
[12:51:45] <CaptHindsight> gearing
[12:52:17] <DRGray> improved torque, accuary
[12:52:24] <CaptHindsight> it's easy to get the ratio required with a belt
[12:52:27] <MrSunshine_> ough, hard to heat straighten when there is two points that its stuck to ... if i heat in one place it pivots it all in two places :P
[12:53:03] <DRGray> what are the normally things that make you want a speciffic ratio? more torque? more accuracy?
[12:53:06] <CaptHindsight> I have belts in positioners that have few arc seconds of repeatability
[12:53:30] <archivist> or what fits in the space
[12:57:09] <DRGray> thats pretty accurate
[12:58:05] <CaptHindsight> 61F bbl...
[12:58:29] <DRGray> CaptHindsight: what do you use your cnc for?
[13:01:56] <Erant> DRGray: I use gearing for my Z-axis servo because it has to lift the head, for example.
[13:02:07] <CaptHindsight> prototypes, custom machines, mechanisms....
[13:33:16] <DRGray> yep
[13:42:55] <DRGray> anybody used on of these?
[13:42:56] <DRGray> http://www.zappautomation.co.uk/electrical-products/stepper-drivers/mx-multi-axis-stepper-drivers/mx3660-three-axis-digital-microstepping-driver.html
[13:45:21] <archivist> cheaper to buy three separate drivers
[13:46:22] <DRGray> yes but sometimes its nice and neat
[13:47:23] <archivist> for me price and convenience of replacement
[13:47:49] <DRGray> yes i guess if one axis breaks you hae to replace the whole unit
[13:48:34] <pcw_home> I think MX3660s are modular ( like Gecko G540s )
[13:48:53] <pcw_home> so you can replace a singe axis drive
[13:48:58] <DRGray> thats good
[13:49:06] <DRGray> so can you plug this straight into a printer port?
[13:49:17] <malcom2073> That's pretty pricey for a leadshine
[13:49:26] <pcw_home> thats the idea
[13:50:47] <DRGray> its 3 steppers and a bob in one
[13:50:53] <DRGray> from my understanding
[13:50:59] <DRGray> drivers i mean
[13:51:00] <DRGray> tired
[13:51:12] <pcw_home> yeah, not bad for 3x 60V 6A ustepping drives and a BOB
[13:51:31] <Duc> makes for a very clean package
[13:51:52] <pcw_home> Tormach uses one in their 440
[13:52:04] <os1r1s> DRGray I read the other day someone pulled that off and put the individual DSP drivers
[13:52:15] <os1r1s> pcw_home Do they really ... interesting.
[13:52:31] <DRGray> well thats what it is
[13:52:37] <DRGray> its all in one
[13:52:48] <DRGray> they do a 4 axis version
[13:53:41] <os1r1s> DRGray Yes, but the review I saw said it was noisier/worse than the individual drives
[13:53:52] <os1r1s> Take it for what its worth
[13:53:56] <DRGray> got a link?
[13:54:39] <os1r1s> Let me see if I can find it
[14:01:38] <CaptHindsight> I used the 3-in-1 for machines that have the PC, power supply and drives etc all in one small enclosure
[14:02:50] <os1r1s> DRGray http://linuxcnc-g0704.blogspot.com/2014/08/electronics.html
[14:08:46] <enleth> https://hackerspace.pl/~enleth/schematic-marked.pdf - a bit unsophisticated but much better than B&W for fast lookup
[14:09:10] <DRGray> CaptHindsight: how have you found them?
[14:14:06] <CaptHindsight> DRGray: http://imagebin.ca/v/2YYYbjToRq41 everything in a small mini-itx case
[14:14:34] <CaptHindsight> I use them to save space and wiring time
[14:15:16] <CaptHindsight> I also integrate the driver into all-in-one touchscreen PC's
[14:18:00] <os1r1s> CaptHindsight Got a pic of that?
[14:18:21] <CaptHindsight> http://imagebin.ca/v/2YYZub4qizRP everything in the touchscreen
[14:18:37] <CaptHindsight> thats controlling a gantry robot
[14:18:49] <os1r1s> CaptHindsight What model screen is that?
[14:19:13] <CaptHindsight> one of the Acer's
[14:19:24] <CaptHindsight> multitouch version
[14:20:36] <os1r1s> CaptHindsight I had tried using an old elo, but it did not work well
[14:21:46] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=9SIA25V30N4519 or similar
[14:22:02] <CaptHindsight> multitouch is a mess in Linux
[14:22:20] <CaptHindsight> but with tweaking regular touch is OK
[14:22:32] <DRGray> what the driver is in the screen?
[14:23:00] <os1r1s> CaptHindsight Do you just use the KB/Mouse from the monitor or do you have another set up?
[14:23:29] <CaptHindsight> thats from 2 years ago, so looks like Ubuntu, Linuxcnc 2.6 and axis
[14:23:51] <CaptHindsight> since it has USB you can do both
[14:24:26] <CaptHindsight> the guy using that machine had to program all his g-code by hand so he added a keyboard and mouse
[14:24:43] <CaptHindsight> but he could run programs easily just off the screen
[14:25:09] <os1r1s> CaptHindsight That's great. I was actually looking for that. Thanks
[14:25:13] <CaptHindsight> so running programs its ok
[14:25:18] <DRGray> my plan is to build a integrated box. so i can use it to run my devices
[14:25:30] <CaptHindsight> but is you have lots to type add a real keyboard
[14:26:27] <CaptHindsight> DRGray: you can see we used a belt on that gantry
[14:26:38] <os1r1s> CaptHindsight I'd mostly run. I had seen some enclosures with a hole for a 15" touchscreen. But now I can't find that.
[14:27:03] <CaptHindsight> ~1.5m belt drive positioner driven by a stepper with a timing belt
[14:27:39] <CaptHindsight> DRGray: ^^^ going back to your stepper and belt question
[14:28:32] <DRGray> yes, i picked up on that
[14:29:27] <CaptHindsight> http://imagebin.ca/v/2YYdKapfx0Bu better pic
[14:30:12] <DRGray> looks good
[14:30:28] <DRGray> so you have mounted the drivers in the atx case?
[14:31:21] <CaptHindsight> yes
[14:31:47] <CaptHindsight> or on the back of the touchscreen
[14:31:50] <os1r1s> CaptHindsight I'd like to see a closeup of that too
[14:32:02] <CaptHindsight> along with the motherboard
[14:32:19] <CaptHindsight> don't have a pic
[14:34:03] <DRGray> in the first pic whats that device doing droping some sort of liquid?
[14:35:43] <CaptHindsight> it has a single dispensing valve
[14:35:49] <DRGray> inking?
[14:36:04] <CaptHindsight> anything you want that will flow
[14:36:16] <DRGray> small droplets?
[14:36:35] <CaptHindsight> or segments
[14:37:05] <DRGray> splatter?
[14:37:11] <CaptHindsight> the valve open/close is ~100ms
[14:37:12] <DRGray> or accurate?
[14:37:28] <CaptHindsight> accurate as the gantry is
[14:37:43] <CaptHindsight> that one was ~30um
[14:38:18] <DRGray> so droplets of ~30um diameter?
[14:38:28] <CaptHindsight> no the accuracy
[14:38:47] <CaptHindsight> with an injet nozzle you can do 30um drops
[14:39:49] <DRGray> so is that stock bough or have you built the dropper setup?
[14:39:52] <CaptHindsight> http://www.microcenter.com/product/422089/Cooler_Master_HAF_Stacker_915R_Mini-ITX_Mod_Tower_Computer_Case you can fit everything into a case this size as well
[14:40:17] <CaptHindsight> custom valve
[14:40:21] <DRGray> sorry for all the questions but it could be useful for a project im working on
[14:42:12] <CaptHindsight> you can buy dispensing valves
[14:42:35] <DRGray> any you’ve had good success with?
[14:42:58] <CaptHindsight> http://www.ebay.com/itm/Dispensing-Valve-SMT-SMD-PCB-Solder-Paste-Adhesive-Liquid-Dispenser-Nordson-NE1-/221964050157?hash=item33ae169eed:g:ytcAAOSwKtlWoe3b
[14:43:04] <CaptHindsight> for reference
[14:43:36] <CaptHindsight> I have success with the ones I make :)
[14:44:12] <CaptHindsight> like everything else, it depends on your experience, skill etc
[14:44:12] <DRGray> hah
[14:44:15] <DRGray> yes
[14:44:19] <DRGray> guess you dont sell them?
[14:45:18] <CaptHindsight> not for cheap
[14:45:20] <CaptHindsight> bbl
[14:46:56] <DRGray> do you build and sell systems?
[15:19:08] <tiwake> CaptHindsight: you know what is not clear to me is when something is anodized, how can we see the color? does the sealing process make the outer oxide layer so thin that the light can pass though it, or does the dye get 'mixed in' with the oxide layer its self?
[15:19:36] <Tom_itx> transparent
[15:19:56] <tiwake> what?
[15:21:03] <Tom_itx> http://www.omwcorp.com/Understanding%20and%20Specifying%20Anodizing.pdf
[15:27:47] <tiwake> Tom_itx: I'm not seeing anything that answers my question in that
[15:28:15] <tiwake> read half of it so far
[15:38:12] <tiwake> Tom_itx: yeah I read the whole thing, it does not answer my question
[15:43:29] <Tom_itx> guess you'll have to ask the captain then
[15:45:09] <gregcnc> The color is in the pore. The aluminum oxide is usually transparent. Corundum is aluminum oxide and varies from transparent to not so much. transparency of anodizing varies with base alloy.
[15:46:18] <pcw_home> I though that the oxide layer was porous (and transparent) so the dye is absorbed in the oxide layer,
[15:46:20] <pcw_home> and the sealant seals the surface to keep the dye from leaching out
[15:48:01] <gregcnc> http://www.kashima-coat.com/global/aluminum/anodized-aluminum.html
[15:49:16] <tiwake> gregcnc: ok so the actual oxide layer is so thin that it allows the light to pass though it to the actual dye
[15:55:01] <gregcnc> the oxide layer itself is transparent. Almost every reference to anodize says AL2O3 is transparent, but I don't know exactly why.
[15:55:39] <evil_ren> thats what i thought, anodizing is transparent matte in finish
[15:56:12] <gregcnc> Anodize doesn't have to be dyed.
[15:57:11] <evil_ren> right and its kinda of grey white when it isnt, like oxidized aluminum
[16:04:48] <miss0r> it turns my problems with this t-slot cutter: it is so dull it probally couldn't cut cheese
[16:05:09] <CaptHindsight> http://ep.yimg.com/ty/cdn/policestuff/why1.jpg http://surface.skku.ac.kr/img/intro_aao_1.gif
[16:05:42] <CaptHindsight> http://www.docsmachine.com/tech/fig2-2.jpg
[16:06:19] <CaptHindsight> tiwake: ^^^
[16:07:01] <CaptHindsight> the anodic layer sits on top of the aluminum a few microns thick
[16:07:31] <tiwake> CaptHindsight: but the dye can "fall out" until its sealed
[16:07:47] <CaptHindsight> or wash out
[16:07:50] <tiwake> CaptHindsight: what I don't understand is why we can still see the dye after its sealed
[16:07:58] <CaptHindsight> sealing swells the pores shut
[16:08:03] <XXCoder> tiwake: alum rust is clear
[16:08:14] <CaptHindsight> the thin layer of oxide is transparent
[16:08:17] <XXCoder> you have never touched alum itself, it rusts over instantly
[16:08:53] <tiwake> ok so it is indeed an oxide layer above the actual dye that is so thin that light can pass though it
[16:09:04] <CaptHindsight> as it gets thicker it becomes more translucent to opaque, as in hard anodize
[16:09:04] <XXCoder> and transparent
[16:09:10] <gregcnc> Sapphire is aluminum oxide, if colored,due to impurities. Sapphire windows or phone glass?
[16:09:14] <XXCoder> there is gem class that IS all alum rust
[16:09:25] <XXCoder> ah sapphire, I couldnt recall name
[16:09:33] <gregcnc> corundum
[16:09:49] <CaptHindsight> it depends on how you control the structure
[16:10:03] <XXCoder> CaptHindsight: same as carbon
[16:10:08] <CaptHindsight> transparent aluminum is clear and may be an inch thick
[16:10:11] <gregcnc> right the crystaline structure has an impact
[16:10:16] <XXCoder> there is many forms of carm structure, including one for diamond
[16:10:24] <XXCoder> *carbon
[16:10:58] <gregcnc> so is each pore essentially a single crystal?
[16:11:09] <tiwake> interesting
[16:11:33] <XXCoder> gregcnc: the setup is designed to shape em
[16:11:40] <XXCoder> so it has holes
[16:11:51] <XXCoder> you then fill em then put em in water and pores close
[16:11:52] <XXCoder> done
[16:11:58] <tiwake> the oxide layer is the entire anodized thing, but the oxide its self is structured to be transparent to (at least) visible light
[16:12:26] <tiwake> and the dye is intermingled with the oxide
[16:13:01] <CaptHindsight> it's physically trapped by the oxide
[16:13:17] <CaptHindsight> when it becomes hydrated
[16:14:00] <tiwake> thats what I suspected, but wasent sure
[16:14:07] <tiwake> well, sorta suspected
[16:15:03] <CaptHindsight> http://www.finishing.com/210/63.shtml
[16:16:27] <CaptHindsight> tiwake: so before and during sealing water based dye can rinse out
[16:16:49] <CaptHindsight> solvent based is not effected by the water so it sticks like glue
[16:17:00] <tiwake> right
[16:28:05] <CaptHindsight> http://www.bluebuddhaboutique.com/blog/wp-content/uploads/2011/08/Self-organized-alumina-membranes-2.jpg this shows the pores depth vs width really well
[16:29:59] <CaptHindsight> http://www.icmm.csic.es/gnmp/wp-content/uploads/2010/04/membranesketch.jpg
[16:30:01] <Deejay> gn8
[16:30:53] <CaptHindsight> I have nano-filters that are just the oxide layer from aluminum anodize
[16:31:10] <CaptHindsight> few microns thick
[16:31:25] <CaptHindsight> with few nm pores
[16:32:09] <CaptHindsight> they anodize and then strip the aluminum base away leaving just the oxide film

[16:35:00] <CaptHindsight> now for the hard stuff... deciphering the instruction manual for a VFD written in Chinglish
[16:57:37] <enleth> idea of the day: use an electric kettle full of water as a braking resistor for the VFD
[16:58:13] <enleth> the worst thing: it would actually work...
[16:59:06] <zeeshan|2> tea and machining
[16:59:07] <zeeshan|2> i like
[17:00:44] <Tom_itx> what's with you canucks and tea?
[17:01:12] <CaptHindsight> kettle full of maple syrup
[17:01:24] <Tom_itx> dude i chat with in another channel drinks it all the time..
[17:03:22] <Tom_itx> i like it when it's cold out
[17:05:02] <enleth> OTOH, a sealed water vessel with a safety valve, a floater for water level monitoring (and possibly replenishment, like in a toilet tank) and of course a heater inside would indeed be a very effective and compact braking resistor
[17:05:16] <enleth> I wonder if anyone used something like this commercially in the days of olde
[17:06:08] <enleth> lots of crazy shit, by today's standards, was once state of the art
[17:24:16] <SpeedEvil> copper sulphate resistors are/were popular as insane-o-power dump resistors for HV stuff
[17:25:20] <enleth> FYI a 600W tourist kettle turns out, if my calculations are right, to be a perfect braking resistor for the 2.2kW inverter I have
[17:25:54] <enleth> if it wasn't so expensive to replace a burnt out inverter, I'd actually give it a try
[17:46:47] <XXCoder> http://makezine.com/2016/02/15/turning-an-hdpe-milk-jug-into-a-motor-pulley/
[17:46:51] <XXCoder> nice
[17:47:16] <XXCoder> I was considering using HDPE to make sheets to cut on cnc router
[17:49:25] <CaptHindsight> http://www.3ders.org/articles/20120715-first-full-sized-3d-printed-milk-jug-boat.html
[17:49:33] <XXCoder> yeah I know of that
[17:49:42] <XXCoder> I didnt know it was pretty millable though
[17:50:38] <CaptHindsight> milkable?
[17:50:53] <XXCoder> that too lol
[17:52:56] <XXCoder> also, guy adds text. it may not be true captions but it is clear and understandabke anyway. subbed
[17:53:43] <XXCoder> hmm apparenrtly it has to be compressed to moldinto single part. harder to make a larger block like that
[17:59:45] <XXCoder> https://www.youtube.com/watch?v=Ov66b2ZwRiQ interesting
[18:09:05] <PetefromTn_> Isn't it typical that just when I have to dismantle the Cincinatt VMC for transport to Florida I get a bunch of order requests for parts LOL
[18:09:16] <Tom_itx> of course
[18:09:25] <FloppyDisk> Murphy helping you...
[18:09:33] <PetefromTn_> Murphy is SUCH an azzhole
[18:09:42] <_methods> https://www.youtube.com/watch?v=RpaoRP70lzM
[18:09:45] <_methods> space x launch
[18:09:50] <XXCoder> it is related to how as soon as you need something you havent needed for quite a while are suddenly hard to find.
[18:10:10] <PetefromTn_> it has been a very productive weekend tho I only have a little bit more work to do here on the house before I move the machines...
[18:11:40] <FloppyDisk> Rigidtapping mesa hostmot2 question: If my index pulse is not exactly one spindle revolution, is that an issue?
[18:12:36] <FloppyDisk> In looking at the hostmot2 component, (bit in/out) index-enable --> When this pin is set to True, the count (and therefore also position) are reset to zero on the next Index (Phase-Z) pulse. At the same time, index-enable is reset to zero to indicate that the pulse has occurred.
[18:13:36] <FloppyDisk> My ISSUE - is that I put the encoder on the back of the spindle MOTOR and not on the spindle itself... I can scale the counts, but how do you scale a 1 count per rev z signal??
[18:13:39] <FloppyDisk> If at all....
[18:14:56] <PetefromTn_> Aw man looks like a downrange safety abort
[18:15:20] <PetefromTn_> I can't wait to be back in Florida and be able to watch these from my backyard ;)
[18:16:20] <_methods> yeah
[18:16:28] <_methods> screwed up valve i guess
[18:16:38] <XXCoder> not a surpise, no captions
[18:17:15] <PetefromTn_> no valve problem there is a ship in the downrange safety area
[18:17:17] <_methods> oh something was in range
[18:17:20] <_methods> yeah
[18:18:29] <PetefromTn_> so is it a hold or an abort?
[18:18:51] <_methods> hold
[18:19:25] <PetefromTn_> Oh cool. launch window is like 76 minutes I think they said...
[18:19:34] <XXCoder> makes sense as ship in range is easily fixable
[18:19:40] <XXCoder> just tell it to buzz off
[18:20:06] <PetefromTn_> yeah man bugger off ;)
[18:20:17] <PetefromTn_> ships take a bit to get somewhere tho
[18:20:37] <PetefromTn_> they retracted the strong arm tho..
[18:21:02] <_methods> t-5 now
[18:21:37] <XXCoder> 5 minutes?
[18:21:53] <_methods> damn t-10 now
[18:22:11] <PetefromTn_> yup
[18:22:13] <PetefromTn_> cool
[18:36:17] <PetefromTn_> Countdown restarted at 11 minutes
[18:36:34] <PetefromTn_> _methods Thank you for posting this link I enjoy watching these...
[18:44:46] <_methods> np
[18:45:05] <_methods> i do too figured most people in here would be interested in the same
[18:46:12] <Sync_> 30s
[18:46:53] <Sync_> abort
[18:47:05] <_methods> ah bummer
[18:49:57] <PetefromTn_> damn
[18:53:32] <XXCoder> why was it aborted?
[18:54:51] <Sync_> no reason yet
[18:55:00] <Sync_> but they are still go for flight eventually
[18:56:06] <XXCoder> ok
[18:58:18] <Valen> looked like fire in the wrong spot to me
[18:58:20] <Sync_> scrubbing
[18:59:32] <enleth> XXCoder: they might not even know yet, the onboard computer aborted by itself
[19:03:55] <Sync_> Launch aborted on low thrust alarm. Rising oxygen temps due to hold for boat and helium bubble triggered alarm
[19:05:17] <enleth> wonder if they sue the idiot boater
[19:05:34] <enleth> what kind of utter fuck one had to be to do this?
[19:06:29] <Sync_> maybe he just did not get the memo
[19:26:19] <XXCoder> what
[19:26:25] <XXCoder> stream have ended?
[19:27:03] <XXCoder> Sync_: really? sucks. :(
[20:39:18] <PetefromTn_> Heh it was probably some guy in a fishing kayak ;)
[20:42:20] <XXCoder> man what a waste
[20:42:29] <XXCoder> they paid thousands bucks to setup
[20:42:38] <XXCoder> and now they gonna de-setup and setup again later
[20:43:15] <PetefromTn_> just had a visit from our boy Connor :D
[20:47:18] <os1r1s> Does anyone know what the wire channels and connectors for the x-stepper, y-stepper, etc is called? https://www.youtube.com/watch?v=qvQ00WmZTuU
[20:47:20] <Tom_itx> better take him to Fl so you can get your tool changer working
[20:50:40] <os1r1s> 18 minutes in
[20:50:45] <PetefromTn_> I know right... we were just laughing about that
[20:50:59] <PetefromTn_> unfortunately there are NO IRC guys down there I don't think...
[20:53:21] <XXCoder> im sure there are
[20:53:26] <XXCoder> just probably not this channel

[21:10:35] <CaptHindsight> I hate it when they fall over
[21:10:48] <malcom2073> It's so sad
[21:10:58] <malcom2073> Like seeing a classic car at the junkyard hehe
[21:11:40] <PetefromTn_> yeesh
[21:12:02] <CaptHindsight> need a better pic of the head
[21:12:19] <malcom2073> Sure you can email him to go out to his driveway and take a better pic :P
[21:12:40] <PetefromTn_> wonder how badly cracked that casting really is
[21:13:03] <CaptHindsight> poor leveling? strong wind? off balance heavy part?
[21:13:39] <malcom2073> Wonder how the head fell off heh
[21:13:51] <malcom2073> maybe that's why it fell off the lift, cause the head bolts broke?
[21:13:56] <malcom2073> ram*
[21:14:02] <CaptHindsight> "The head looks good and I don't see any cracking."
[21:14:58] <XXCoder> ouch
[21:15:07] <XXCoder> well $1 is WAY below scrap
[21:15:13] <CaptHindsight> http://i.ebayimg.com/images/g/yiEAAOSw~OVW01~l/s-l1600.jpg
[21:15:13] <PetefromTn_> man I am tired, we did a LOT of work on our house this weekend.. Still got a few things to do tho :(
[21:15:20] <malcom2073> If the ballscrews are ok, could be a good salvage
[21:15:34] <CaptHindsight> probably fine
[21:15:57] <CaptHindsight> ballscrews are Carl Zeiss ground precision screws (I don't remember if they are .0005 or .0001 precision and these were big $)
[21:16:16] <CaptHindsight> the Y axis mount is trashed.
[21:18:32] <CaptHindsight> malcom2073: near you? http://www.ebay.com/itm/Supermax-Model-Max-1-Rebel-CNC-Machining-Center-20-ATC-with-Fanuc-OM-Control-/182036843622
[21:19:07] <malcom2073> CaptHindsight: Only two hours away
[21:19:26] <malcom2073> oo free loading, what's it weigh you think?
[21:20:02] <malcom2073> 7600lbs
[21:20:09] <malcom2073> over the weight limit for my trailer haha
[21:20:20] <CaptHindsight> 4 skateboards and a rope
[21:20:52] <malcom2073> Have to be murca skateboards to handle the weight
[21:20:58] <CaptHindsight> a trailer that size is probably $70/day
[21:21:06] <malcom2073> Eh, like $130
[21:21:07] <malcom2073> still worth it
[21:21:30] <malcom2073> Dunno if my SUV could haul it, my 7000lb trailer is close to the limit when fully loaded heh
[21:21:58] <malcom2073> I could buy it, stick steppers on it ;)
[21:32:56] <PetefromTn_> Well Gn8 All..
[21:45:58] <enleth> old contactor motor control removed from the bridgeport's cabinet, all is ready to connect the VFD properly. before: http://i.imgur.com/1rIRDbA.jpg after: http://i.imgur.com/F2tIdvA.jpg
[21:47:25] <enleth> lots of time spent on replacing power wires that used terminals of the removed contactors to branch off and suddenly got too short to reach the next contactor on their own
[22:18:44] <zeeshan|2> enleth nice
[22:19:08] <zeeshan|2> i had to pick some terminal blocks for work
[22:19:30] <zeeshan|2> i hate having dangling diodes/movs outside a terminal block
[22:19:34] <zeeshan|2> or even resistors
[22:19:48] <zeeshan|2> came across eaton terminal blocks that actually allow you to "plug" in resistors/caps/movs
[22:19:48] <zeeshan|2> etc
[22:19:51] <zeeshan|2> its soooo clean
[22:19:55] * zeeshan|2 needs to convert to those
[22:40:04] <Tom_itx> nice one
[22:58:25] <enleth> zeeshan|2: the good thing about working with this machine is that every single wire is numbered with those slide-on color-coded digit markers.
[22:58:28] <enleth> on both ends
[22:58:40] <enleth> even wires 5cm long are marked on both ends
[23:04:58] <enleth> and the schematic even denotes the highest wire number used, gaps left in numbering for future use and so on
[23:36:16] <pink_vampire> hi
[23:37:53] <pink_vampire> why there is no 1mm R8 collet??
[23:37:56] <pink_vampire> :(
[23:40:59] <XXCoder> hey
[23:41:27] <XXCoder> R8 is pretty dang tiny
[23:41:34] <pink_vampire> hi XXCoder
[23:41:45] <XXCoder> is there sizes r8 can hold thats bigger than 1mm?
[23:41:53] <XXCoder> im sure yes
[23:42:24] <pink_vampire> the smallest I can find is 2mm
[23:42:33] <pink_vampire> but is too big.
[23:42:53] <CaptHindsight> use an R8 chuck
[23:43:23] <XXCoder> you mean ER collets?
[23:43:38] <XXCoder> as my ER 11 collection includes 1mm holder
[23:43:48] <CaptHindsight> R8 to jacobs chuck
[23:44:34] <pink_vampire> I know about all this adapters to ER
[23:44:45] <pink_vampire> but I want to work direct.
[23:45:20] <XXCoder> whats werong with er?
[23:46:54] <pink_vampire> add more run-out.

[23:48:30] <XXCoder> though some runouts is either acceptable or controllable
[23:48:32] <FloppyDisk> Looks like you can find 1/16", but I didn't see smaller.
[23:48:36] <XXCoder> I use er all time at work
[23:48:45] <FloppyDisk> You need a larger shank size then.
[23:48:46] <CaptHindsight> http://www.shars.com/r8-er16-er-collet-holder
[23:49:11] <XXCoder> usually all fine, even with applications where tol is rather sensive (+- .005)

[23:49:36] <XXCoder> reamer I just use dial indictor and dead blow hammer to be sure it is stright
[23:49:54] <XXCoder> thats where reamer really have to be very stright, usually fine
[23:50:01] <CaptHindsight> is the hammer for bending the end mill?
[23:50:13] <XXCoder> never used it for end mill
[23:50:27] <CaptHindsight> reamer?
[23:50:31] <XXCoder> yeah
[23:50:48] <pink_vampire> I getting white page on shars website

[23:53:35] <XXCoder> heh I'm lucky er11 collets fit my grinder
[23:53:55] <XXCoder> so rather than specific 8mm size I can use whatever range er11 fits
[23:54:05] <XXCoder> er was it 6mm whatever
