[00:00:09] <WalterN> heh
[00:00:31] <WalterN> with laser sintering, do a sugar frame for the cake
[00:00:47] <WalterN> with some frosting, that could look pretty freeking amazing
[00:01:12] <r00t4rd3d> just get nasa to help you build the sintering machine
[00:01:48] <WalterN> NASA can go screw themselves
[00:02:07] <r00t4rd3d> FUCK YOU, PLUTO'S REAL!
[00:02:12] <WalterN> lol
[00:02:51] <WalterN> that would be funny if SpaceX CEO claimed pluto as his own planet
[00:03:04] <r00t4rd3d> land on it and take a shit
[00:03:09] <r00t4rd3d> this mine!
[00:03:15] <WalterN> haha
[00:04:12] <FinboySlick> Space X is John Carmack, right?
[00:04:16] <FinboySlick> Or is that Armadillo?
[00:04:52] <WalterN> I dont remember... whichever sold paypal to ebay
[00:04:59] <r00t4rd3d> Houston we have an anomaly.
[00:05:17] <FinboySlick> Elon Tesla-motors Musk.
[00:07:57] <r00t4rd3d> I would just start with a laser engraver, build a xyz table
[00:08:07] <FinboySlick> I can't blame him for trying, but I find his sucking up to government because he can't build a proper car kind of disappointing.
[00:08:14] <r00t4rd3d> slap a 250w laser on it
[00:08:34] <WalterN> r00t4rd3d: 250 watts in the beam?
[00:08:39] <WalterN> or input power?
[00:09:06] <r00t4rd3d> ive just read where thats like the minimum laser size to use
[00:09:31] <r00t4rd3d> for engraver/cutter
[00:09:32] <WalterN> 25watt beam sounds about right for engraving
[00:10:05] <WalterN> somewhere I read 200 watt beam for metal laser sintering
[00:10:09] <r00t4rd3d> you will want to cut too
[00:10:44] <WalterN> hmm
[00:10:49] <WalterN> why?
[00:11:03] <r00t4rd3d> then you can make stuff to engrave
[00:11:20] <WalterN> oh, well, engrave, yeah
[00:12:43] <aitek> is there a g code to reload subroutines read only parameters?
[00:13:05] <WalterN> say I get a 75 watt laser, and I only want something like 30 watts... would I have to pulse the laser? or could I just cut back the input power?
[00:14:00] <r00t4rd3d> You are better off waiting till 9-10am eastern time for tech questions
[00:14:09] <aitek> ok thanks
[00:15:47] <r00t4rd3d> you writing gcode from scratch ?
[00:17:57] <WalterN> oh, that would also depend on feed rate
[00:18:12] <WalterN> power density and feed rate
[00:18:17] <WalterN> and material
[00:19:04] <r00t4rd3d> yeah if you move a 1w laser as fast as a 500w one, you would get drastically different results
[00:23:11] <r00t4rd3d> just get a wood router and make balsa airplanes
[00:23:34] <r00t4rd3d> well you could do that with a laser too i guess
[00:29:56] <WalterN> everything can be done with a laser
[00:30:25] <WalterN> like blowing up planets
[00:31:32] <WalterN> how is multi-color stuff done?
[00:41:36] <WalterN> meh
[00:41:46] <WalterN> I think its time to play some computer games or something
[01:33:30] <r00t4rd3d> Damn, Google Fiber is going to Austin.
[01:41:11] <Loetmichel> mornin'
[01:44:53] <Loetmichel> *bah* ... seventh of april and i had to clean my car winows from ice to drive to the bakery... the weather is broken!
[01:48:58] <AITEK2012> hello ?
[02:00:16] <DJ9DJ> moin
[02:10:48] <Loetmichel> *gnah* ... i am the biggest idiot running around.. ONE power strip on the floor. and i thrip and spill my coffee in it... RCD switched the whole flat off :-(
[02:14:46] <t12> i wonder if hplc pumps + hosing + valves make for good oilers
[07:03:18] <grandixximo> Is there a way to refresh subroutine read only parameters?
[07:04:10] <grandixximo> Like parameter 5410 tool diameter to update after a g10 L10
[07:04:32] <grandixximo> It doesn't seem to update right now
[07:04:49] <grandixximo> Is there a special g code to refresh it?
[07:06:14] <mhaberler> could you file a bug with a script to reproduce, including version?
[07:08:25] <mhaberler> dont forget a screenshot: http://www.bfst.de/funpix/screenshot.jpeg
[07:09:00] <jthornton> that's a screen shot for sure
[07:09:39] <mhaberler> "needs service" - here are some explanatory comments: http://imgur.com/rDhhgEz
[07:09:48] <Loetmichel> ... looks like fine (bird) buckshot ;-)
[07:10:15] <mhaberler> "Try pressing F8 as it boots up. "
[07:15:32] <grandixximo-i910> I made a post in the forum on the g code section
[07:15:44] <grandixximo-i910> I'll file a bug ASAP
[07:17:04] <grandixximo-i910> Sorry something came up afk for 20min
[07:26:32] <grandixximo-i910> Sorry
[07:27:34] <grandixximo-i910> http://linuxcnc.org/index.php/english/forum/20-g-code/26374-subroutine-that-change-the-tool-diameter
[07:31:37] <mhaberler> few developers will look at the forum for bug repors - if you want to haev it fixed, I suggest adding a bugtracker entry. And which version of linuxcnc are you running?
[07:31:39] <andypugh> I think what is happening there is related to the way that G-code is interpreted and queued. The fact that a dummy toolchange gives the effect required is a hint. Toolchange is a "queuebuster" and a whole new path is computed after it.
[07:32:25] <andypugh> I think that there is an implicit assumption that the tool diameter does not change between toolchanges.
[07:33:01] <andypugh> However, have you tried a G43 after your G10?
[07:33:06] <grandixximo> I'm on 2.5
[07:33:50] <grandixximo> I didn't try g43
[07:34:02] <andypugh> In fact, I am susrpised not to see a G43 with the M6
[07:34:17] <jthornton> gotta use G43
[07:35:04] <grandixximo> G43 loads axis comp
[07:35:11] <grandixximo> Axis offset
[07:35:19] <grandixximo> Will it load diameter also?
[07:37:27] <jthornton> I'd have to read the manual to be sure
[07:37:37] <grandixximo> I'll try with g43
[07:40:16] <grandix> Adding g43 does not seems to change anything
[07:41:14] <grandix> I'm working on x y and g43 loads tool length on z
[07:41:27] <grandix> So nothing changes
[07:42:31] <jthornton> yea g43 is tool length offset
[07:43:04] <jthornton> g10 l10 is set tool table
[07:44:19] <andypugh> I thought that G43 loaded the diameter too.
[07:44:37] <andypugh> It has never mattered to me to know :-)
[07:44:47] <grandix> It doesn't
[07:45:37] <grandix> Yeah i know most of you guys don't polish and don't need have a live waste on your tools and don't work a lot with g42
[07:46:03] <jthornton> T1 M6
[07:46:11] <jthornton> (debug, #5410)
[07:46:18] <jthornton> G10 L10 P1 R.25
[07:46:27] <jthornton> (debug, #5410)
[07:46:35] <jthornton> the above works for me
[07:47:03] <grandix> Make the debug a subroutine
[07:47:25] <grandix> I'll try
[07:47:31] <jthornton> subroutine in the same file or a called subroutine?
[07:48:20] <andypugh> jthornton: Was that MDI or Gcode file?
[07:48:27] <jthornton> MDI
[07:48:29] <grandix> g code
[07:50:11] <jthornton> I just ran it in g code and it worked
[07:51:10] <grandix> Then it must be my version I'll update
[07:51:57] <jthornton> I just ran as a sub and it worked
[07:52:15] <grandix> Not working for me
[07:52:20] <andypugh> I would be really surprised if there has been a change in this between 2.5 and 2.5.2
[07:52:39] <jthornton> http://pastebin.com/gbHpKJNG
[07:52:51] <jthornton> pastebin what your doing grandix
[07:52:52] <grandix> The changes take effect only after i play the second time
[07:54:45] <aitek> i wrote the same code as you did in here i added m2
[07:54:49] <aitek> and run as gcode
[07:55:24] <aitek> the first time i run it get the original diameter twice, and then the changed diameter
[07:56:44] <grandix> Aitek is always me
[07:56:54] <grandix> Only from the pc
[07:57:16] <grandix> :-)
[08:00:41] <aitek> http://pastebin.com/M4wnh1G0
[08:00:46] <aitek> this is what i'm running
[08:01:05] <aitek> i always get 60.0000
[08:03:14] <jthornton> I get .25 at that was the tool dia before running your code then 30. and 60.
[08:03:45] <jthornton> running again I get 60 30 60
[08:03:52] <aitek> i get 60 60 60
[08:04:03] <aitek> i did have make some changes to the code
[08:04:13] <aitek> i might have screw up something then
[08:04:26] <aitek> i'll reinstall from build bot
[08:04:40] <aitek> are you using 2.5?
[08:04:48] <jthornton> now you tell me your not using stock LinuxCNC
[08:04:49] <jthornton> yes
[08:06:43] <aitek> i did some very minor changes in the tool change
[08:07:03] <jthornton> I'm guessing not so minor now...
[08:07:23] <aitek> i'm guessing so too, i'll try with stock and let you know
[08:10:01] <aitek> ok installed from source it's working
[08:10:08] <aitek> sorry
[09:34:26] * Tom_itx removes bullet from aitek's foot
[09:38:59] <skunkworks> ?
[10:05:57] <Felix29> is there anybody in the chicago area?
[10:10:02] <sadara> yes
[10:10:06] <sadara> Millions of ppl
[10:10:31] <L84Supper> there is a couple
[10:11:10] <Felix29> I am looking for someone who could make me a couple pieces from 1/4" 6061
[10:11:36] <L84Supper> are they small enough to UPS?
[10:11:39] <Felix29> small pieces and compensation can be worked out
[10:12:21] <Felix29> yeah i'm checking dimensions of the largest piece right now
[10:12:45] <Felix29> 14"x6" is the largest
[10:13:08] <L84Supper> maybe somebody in the midwest would be interested
[10:13:15] <Felix29> yeah i figured
[10:13:23] <Felix29> if there's somebody here - great
[10:13:29] <Felix29> otherwise i'll post it on cnczone
[12:12:19] <IchGuckLive> hi all B)
[12:12:24] <Felix29> hi
[12:12:51] <IchGuckLive> nice weather here in germany but still cold
[12:13:08] <Felix29> indiana is the same way today
[12:13:21] <Felix29> let's not jinx it, there has been snow in late april before
[12:15:31] <IchGuckLive> here 2
[12:16:35] <IchGuckLive> Felix29: did you look after the sbr modificatrion on your router
[12:17:48] <Felix29> yeah
[12:17:56] <Felix29> i know what i wanna do now
[12:18:06] <Felix29> first of all, i need to replace all the plastic crap
[12:18:07] <IchGuckLive> cheep afortable and good on your router with less mods
[12:18:38] <IchGuckLive> think on SC 2 with harden pins it might better fit your frame
[12:19:10] <IchGuckLive> and the SC gets you a better price
[12:19:22] <Felix29> i found local people around
[12:19:32] <Felix29> i'll see if they can cut some things for me
[12:19:39] <Felix29> so i'll completely redo the frame
[12:19:44] <IchGuckLive> good to go
[12:20:21] <Felix29> that way, i can also asjust my frame size to the linear mechanism i'll get
[12:20:53] <Felix29> actually, i liked the slides on ebay
[12:21:31] <Felix29> http://www.ebay.com/itm/CNC-Set-12x-300mm-Linearfhrung-Linear-Guide-Rail-Stage-/221205563001
[12:21:42] <Felix29> i think i might get these and build my frame around it
[12:21:51] <Felix29> only problem is they don't ship to the us
[12:22:34] <IchGuckLive> i woudt go direct china
[12:22:42] <IchGuckLive> 10pc for 35USD
[12:22:59] <Felix29> yes, there is a guy here who buys from china
[12:23:06] <Felix29> i'll talk to him and see what he recommends
[12:23:23] <Felix29> the plan is to take 80/20 for the frame
[12:23:36] <Felix29> and those affordable slides
[12:23:43] <Felix29> that way, it shouldn't be too bad
[12:25:55] <IchGuckLive> if you go may think about long slide trails better then short you miss mashine space but you gain precision and stability
[12:28:34] <Felix29> for now, i need to figure out how to do the mechanical part
[12:28:46] <Felix29> which means if i can cut some mounting adapters and such
[12:29:00] <Felix29> once i have that figured out, i'll pull the trigger and buy the slides
[12:29:30] <L84Supper> isn't 80/20 near Fort Wayne, IN?
[12:29:38] <Felix29> yeah
[12:29:58] <Felix29> there's also minitec somewhere around i think
[12:30:14] <IchGuckLive> ,initek is here in town 2
[12:30:20] <IchGuckLive> m
[12:30:54] <L84Supper> Faztek
[12:32:53] <L84Supper> there are several t-slot extruders in China, what I haven't found is a supplier that provides finished t-slot services, cutting, drilling, tapping etc
[12:33:16] <Felix29> i was looking around, too
[12:33:22] <Felix29> i guess minitec will do it
[12:33:34] <L84Supper> no loyalty to Bosch? :)
[12:33:39] <Felix29> but i was rather looking for a machine shop that will make parts
[12:33:59] <Felix29> i contacted some, but they were all just larger orders
[12:34:29] <L84Supper> http://www.d2p.com/ShowInfo
[12:34:34] <IchGuckLive> L84Supper: minitec does this
[12:34:52] <IchGuckLive> you can order there at 0.2mm accuracy
[12:34:58] <L84Supper> IchGuckLive: sure, but I'm trying to find some supplier similar in China
[12:35:04] <IchGuckLive> and they als supply full axis
[12:35:15] <IchGuckLive> agree on that
[12:35:23] <L84Supper> all of them do in the US and the EU
[12:35:30] <IchGuckLive> woudt be good to have this cheep
[12:35:46] <L84Supper> in China it's just sold in bulk from the extruder/mill
[12:36:09] <L84Supper> Felix29: http://www.d2p.com/Exhibiting check this list
[12:36:19] <IchGuckLive> and the precision is offen worse
[12:36:54] <L84Supper> you just have to get on their back about it, they have the same equipment in China s anywhere else
[12:37:44] <ReadError> L84Supper, the guy that i got my router from
[12:37:47] <ReadError> hes got a supplier that does it
[12:37:56] <IchGuckLive> ive seen t-slots as a hell of mounting out of china
[12:38:50] <Felix29> that shaumburg convention is close
[12:38:59] <ReadError> the adults erector set :)
[12:39:08] <Felix29> but isnt that for people who want to build like a couple hundred units?
[12:39:52] <L84Supper> I just need to learn more Chinese
[12:40:17] <Felix29> well, the minitec things are 0.01" repeatability
[12:40:41] <L84Supper> some things just don't translate well, especially when you're translator has never seen or heard of what you're asking about
[12:40:43] <Felix29> even with the plastic in my machine, i'm already better than that
[12:40:51] <L84Supper> your/you're
[12:46:25] <IchGuckLive> L84Supper: ask ktHK here he is in the center oh HK and ships near everything
[12:47:01] <L84Supper> http://szztly.en.alibaba.com/productlist.html?domain_name=szztly.en.alibaba.com just over the hill from Hong Kong
[12:47:38] <L84Supper> have to find someone farther north
[12:54:40] <L84Supper> now I find one
[13:02:08] <L84Supper> is anyone in this channel from China, Japan, Korea, Singapore or Thailand?
[13:10:25] <r00t4rd3d> lol
[13:11:26] <r00t4rd3d> trying to get a deal on parts?
[13:12:11] <L84Supper> I'm there half the time
[13:12:29] <r00t4rd3d> and the other half?
[13:12:40] <L84Supper> stuck in the US
[13:12:56] <r00t4rd3d> what do you do over there?
[13:13:31] <L84Supper> 3D printers/additive manufacturing
[13:14:22] <r00t4rd3d> teaching the next generation of counterfitters
[13:15:38] <r00t4rd3d> can I go once and be your button pusher?
[13:16:14] <L84Supper> if it leaves out the front door it's a brand name item, if it leaves out the back door from the same factory its bootleg
[13:16:19] <L84Supper> is that what you mean?
[13:17:25] <L84Supper> they are drawn to western brands but just recently they have been starting their own labels
[13:17:56] <r00t4rd3d> id like to goto japan and take pictures
[13:18:50] <L84Supper> Japan is fun
[13:19:20] <L84Supper> Australia is covered, and some one used to lurk in here from India
[13:19:54] <L84Supper> they have a really big hacker, cnc, robot making culture in Japan
[13:20:13] <r00t4rd3d> so you get paid to go show them how to use a 3d printer?
[13:20:38] <r00t4rd3d> and teach them broken engrish on the side
[13:22:08] <L84Supper> heh, we manufacture them there
[13:23:24] <r00t4rd3d> send me a prototype
[13:23:39] <L84Supper> the US put a few $M into 3D print incubator in Ohio, China put $100M into their own
[13:24:40] <L84Supper> http://namii.org/
[13:25:20] <r00t4rd3d> looks like a ceo shit that site out.
[13:25:30] <L84Supper> http://www.3ders.org/articles/20130205-china-to-invest-8m-in-3d-printing-innovation-center.html
[13:26:34] <WalterN> anyone awake that knows more about laser sintering rapid prototyping machines?
[13:27:00] <L84Supper> WalterN: what are you looking for?
[13:27:17] <L84Supper> plastic or metal powder? both?
[13:27:26] <WalterN> kinda both... though mostly plastic
[13:27:52] <L84Supper> do you want to make one?
[13:27:52] <WalterN> what kind of power I need and power density when the beam hits the powder
[13:28:03] <WalterN> oh, yeah... kinda
[13:28:08] <L84Supper> oh, all depends on the materials
[13:28:17] <WalterN> right... so.. plastic :P
[13:28:25] <L84Supper> and how fast you want it to build parts
[13:28:32] <WalterN> yeah
[13:28:58] <L84Supper> some are up to 200W, but build parts very rapidly, few liters per hour
[13:28:59] <WalterN> material, feed rate, and the power of the laser(power density)
[13:29:29] <L84Supper> laser spot size
[13:29:33] <WalterN> aye
[13:29:43] <WalterN> and I really dont know what sane values are for all of that
[13:30:33] <L84Supper> 100um spot size and 100W can do just about anything including metals
[13:30:53] <WalterN> ok
[13:31:07] <L84Supper> some metals require a special atmosphere, like welding
[13:31:12] <WalterN> then its only adjusting feed rate for the different kinds of materials
[13:31:20] <WalterN> oh yeah
[13:31:34] <L84Supper> you modulate the laser along with the speed it travels
[13:31:36] <WalterN> what about heating up the materials before laser sintering?
[13:32:00] <L84Supper> yes, then there is less energy required to reach their melting point
[13:32:10] <sadara_> 100um spot size is difficult to achive
[13:32:12] <L84Supper> say the Tg is 210 deg C
[13:32:28] <L84Supper> you can use a larger spot if you find it difficult
[13:33:11] <WalterN> I found this last night... http://www.parallax-tech.com/faq.htm
[13:33:19] <sadara_> I think for hobby applications, plasma sintering might be easier
[13:33:29] <L84Supper> if you heat the powder to say 180 deg C then it only needs to rise 30 deg C or higher to melt rather than 190 C from room temp
[13:33:52] <L84Supper> depends on your level of skill
[13:34:16] <L84Supper> I don't recommend anything laser for DIY
[13:34:20] <WalterN> sadara_: I'm not really doing this for a hobby though... going to use ballscrews and stuff to make the machine properly
[13:34:28] <sadara_> If your talking plastics sintering, then that should be very easy
[13:35:07] <WalterN> I plan on spending in excess of $5,000 after everything
[13:35:09] <L84Supper> we have laser spots down to 1um pretty easily
[13:35:11] <WalterN> (heh)
[13:35:26] <WalterN> not sure how much lasers cost though
[13:35:30] <sadara> I would also allow the design to function with UV curing resins
[13:35:31] <L84Supper> two photon initiation is down to 100nm
[13:35:32] <WalterN> or optics
[13:36:01] <sadara> L84Supper: At what wavelength?
[13:36:42] <L84Supper> wavelength for ?
[13:36:46] <sadara> and what laser chemistry?
[13:37:08] <sadara> 100nm is well below the wavelength of most lasers
[13:37:22] <sadara> That is approching x-rays
[13:37:57] <L84Supper> you can look up two photon absorption
[13:38:03] <L84Supper> it's a quantum effect
[13:38:04] <WalterN> maybe microns?
[13:38:20] <L84Supper> it's more about short pulse duration than wavelength
[13:38:34] <L84Supper> no it's nanometers
[13:38:53] <L84Supper> http://www.technologyreview.com/news/511856/micro-3-d-printer-creates-tiny-structures-in-seconds/
[13:40:21] <L84Supper> WalterN: if you dig around the specs for SLS printers you'll find what you're looking for
[13:40:51] <sadara> That article is about MEMS mirrors
[13:41:13] <L84Supper> Micro 3-D Printer Creates Tiny Structures in Seconds
[13:41:20] <L84Supper> ^^ that one?
[13:43:34] <L84Supper> WalterN: http://www.alibaba.com/product-gs/527840103/CO2_Laser_Galvo_Mirror.html
[13:43:36] <sadara> Is that your comapny?
[13:43:49] <L84Supper> WalterN: http://www.alibaba.com/product-gs/611542074/10_6um_galvo_mirror_scan_mirror.html
[13:44:01] <L84Supper> sadara: no, we have a faster process
[13:44:11] <sadara> Magic? :)
[13:44:37] <L84Supper> almost seems like it
[13:45:03] <WalterN> ..?
[13:45:20] <L84Supper> http://www.asdn.net/asdn/nanotools/two-photon_polymerization.shtml
[13:45:35] <sadara> Reading about it now
[13:45:40] <L84Supper> WalterN: galvos steer the laser beam to the powder bed
[13:45:54] <sadara> How do you track what phase the laser will be in?
[13:46:02] <L84Supper> it's much faster than a XY scanning stage with linear motors
[13:46:20] <sadara> You could also use a couple of DLPs
[13:46:46] <sadara> or are they only 2 direction... nm
[13:47:11] <WalterN> oh yeah, with the liquid plastic stuff
[13:47:27] <sadara> can you get 2 axis/3axis galvonometers?
[13:47:41] <L84Supper> galvos yeah
[13:47:56] <L84Supper> each mirror is only 1 axis
[13:47:59] <sadara> third axis been linear, rather than rotational for focus
[13:48:15] <sadara> I mean a single mirror 2 or 3 axis
[13:48:33] <L84Supper> piezo
[13:48:39] <sadara> I have a system here that uses 2 galvos, (not laser)
[13:48:55] <WalterN> no idea what you are talking about... lol
[13:49:07] <L84Supper> sadara: what are you steering?
[13:49:20] <sadara> have you seen a VU meter on a audio amplifier, the old school needle ones?
[13:49:46] <sadara> Its for an active image stabliser for a spotting scope
[13:49:51] <L84Supper> seen, you mean worked with for several years :)
[13:50:05] <sadara> WalterN: have you seen a VU meter on a audio amplifier, the old school needle ones?
[13:50:19] <WalterN> what is a VU meter?
[13:50:37] <sadara> the needle or lights that pulse with the music
[13:50:52] <L84Supper> WalterN: https://www.youtube.com/watch?v=-sG2kG2_osA
[13:51:36] <WalterN> Standard Volume Indicator
[13:51:50] <sadara> a galvo is like the old analog needle gauges, but instead of the needle, you have a mirror
[13:51:54] <L84Supper> https://www.youtube.com/watch?feature=endscreen&NR=1&v=FqjqEY8Zupk better video
[13:51:57] <WalterN> so just an analog voltage meter?
[13:52:17] <sadara> when you change the current through it, the mirror changes angle
[13:52:35] <WalterN> oOo
[13:52:59] <L84Supper> Casio makes a laser projector
[13:53:14] <L84Supper> you can use it for SLS plastic
[13:53:23] <sadara> interisting
[13:53:27] <L84Supper> with its 470nm lasers
[13:53:57] <L84Supper> https://www.youtube.com/watch?v=0a7BzDsKNs8 this video shows the galvos really well
[13:54:23] <sadara> that is the most over the top control system I've ever seen for a galvo, my system uses a single pcb about 1x1 inch
[13:54:40] <L84Supper> heh
[13:55:20] <WalterN> how would the laser focus on a specific spot when the path the light is taking changes... without a lense to adjust?
[13:55:51] <L84Supper> http://www.edmundoptics.com/lasers/laser-optics/laser-optic-assemblies/f-theta-scanning-lenses/2961
[13:56:23] <L84Supper> if the bean is well collimated then there's nothing to focus
[13:56:37] <L84Supper> same for a beam
[13:56:52] <sadara> and if it's not, you have a third galvo that adjusts focus
[13:56:59] <L84Supper> I ever collimated a bean before ;)
[13:57:14] <sadara> ever ever?
[13:57:28] <sadara> Your typing is as bad as mine...
[13:57:30] <L84Supper> my n key is flakey
[13:57:42] <L84Supper> have to press it hard
[13:57:50] <L84Supper> time for new keyboard again
[13:57:50] <WalterN> nnnnnnuuuuuu
[13:58:00] <WalterN> get a real mechanical keyboard
[13:58:09] <L84Supper> this one lights up in the dark
[13:58:15] <WalterN> so does mine
[13:58:30] <sadara> g15 all the way
[13:58:31] <L84Supper> have a make and model
[13:58:42] <WalterN> razer blackwidow
[13:59:00] <sadara> there is your problem
[13:59:20] <WalterN> the razer blackwidow ultimate is the cheapest backlit mechanical keyboard in production
[13:59:20] <sadara> it doesn't have a LCD screen intergrated into it
[13:59:25] <L84Supper> either they keys wear out or the letters wear away
[13:59:37] <L84Supper> this is a Saitek
[14:00:22] <L84Supper> http://www.razerzone.com/gaming-keyboards-keypads/razer-blackwidow-2013/ does is hold up well?
[14:00:34] <sadara> noooo
[14:00:39] <sadara> really nooo
[14:00:41] <L84Supper> 2-3 years at most is what I get from keyboards
[14:00:45] <WalterN> yeah, it has a nice build
[14:00:58] <WalterN> I've had mine for a couple years now
[14:01:07] <sadara> I took mine back, and went back to using my g15
[14:01:15] <sadara> (not that I like the g15 much
[14:01:30] <WalterN> sadara: why? the keys are cherry MX blue if I recall correctly
[14:02:01] <sadara> the keys weer "weird".... and would keep double typing
[14:02:08] <DJ9DJ> namd
[14:02:09] <WalterN> hmm
[14:02:14] <WalterN> never had that issue
[14:02:20] <L84Supper> http://www.logitech.com/en-us/product/g19-keyboard-for-gaming?crid=26 for $200 is better give me a massage
[14:02:35] <WalterN> did you install drivers? cause I didnt
[14:03:07] <sadara> no
[14:03:10] <sadara> It's a kb
[14:03:19] <WalterN> (just wondering)
[14:03:27] <sadara> if a kb needed drivers to type, i would take it back and say it was defective
[14:03:57] <sadara> I have a driver (kinda, more like an app) to make my g5 lcd work
[14:04:12] <sadara> s/g5/15
[14:04:19] <WalterN> L84Supper: the blackwidow is not the backlit one... though you could solder in your own LEDs (so I've read) the black widow ultimate has the same PCB only with the LEDs for back light soldered in
[14:04:47] <sadara> http://en.wikipedia.org/wiki/Optimus_Maximus_keyboard <- top of the line
[14:05:04] <WalterN> screw that
[14:05:10] <WalterN> I'd rather have a new computer
[14:05:11] <WalterN> lol
[14:05:21] <sadara> sigh, me too
[14:05:31] <sadara> I want someone to buy one though
[14:05:45] <WalterN> and before a new computer I'd rather make a CNC machine
[14:05:48] <sadara> so they can tell me if it is as awsome as it should be
[14:05:54] <WalterN> which is why I asked about laserness :P
[14:06:05] * sadara is making one as we speak
[14:06:26] <WalterN> shiny :3
[14:06:30] <sadara> well, designing the W-axis spindle
[14:06:41] <WalterN> W?
[14:07:13] <L84Supper> WalterN: I was wondering what you meant by focus the laser? to smaller spot size than what leaves the source?
[14:07:20] <WalterN> L84Supper: yeah
[14:07:37] <WalterN> is that what is needed even?
[14:08:05] <L84Supper> if the beam is well collimated then no
[14:08:39] <WalterN> I know a guy who is (was anyway) making an 80watt laser... thats really my only souce on how lasers work from a practical standpoint
[14:08:39] <sadara> C axis rotates around Z, W-axis it the linear form of C
[14:09:08] <sadara> There is now way I'm going to try and explain W axis on IRC, we would be here for a very long time
[14:09:37] <WalterN> L84Supper: also, http://www.overclock.net/t/491752/mechanical-keyboard-guide
[14:10:02] <sadara> WalterN: http://www.efunda.com/processes/machining/images/mill/millCNCaxes1.gif
[14:10:13] <WalterN> cherry MX blue is the most common I think
[14:10:17] <L84Supper> http://www.iiviinfrared.com/CO2-Laser-Optics/scanning-laser-system-optics.html
[14:11:03] <L84Supper> for a small field up to 250mm
[14:11:08] <WalterN> sadara: oh ok... I was thinking lathe XD
[14:11:11] <sadara> that machine rotates W aroung B, mine rotates W around Z (C)
[14:12:22] <L84Supper> I saw that in a James Bond movie
[14:13:30] <WalterN> L84Supper: I'm kinda confused as to what I need now... uh..
[14:13:51] <L84Supper> depends on what you want to do, what size and materials
[14:13:55] <L84Supper> start from there
[14:14:05] <L84Supper> what bed size?
[14:14:06] <WalterN> actual printing size?
[14:14:09] <WalterN> yeah
[14:14:10] <L84Supper> yeah
[14:14:10] <WalterN> hmm
[14:14:18] <WalterN> good sized
[14:14:22] <WalterN> but not huge
[14:14:24] <WalterN> XD
[14:14:33] <L84Supper> 200mm XYZ?
[14:14:48] * WalterN does some converting
[14:14:59] <L84Supper> 10" XYZ
[14:15:15] <L84Supper> 200mm = ~ 8"
[14:15:22] * WalterN grabs tape measure to better visualize
[14:16:05] <WalterN> maybe 18"?
[14:17:04] <WalterN> that seems like a good size... is it too big?
[14:17:50] <L84Supper> http://www.youtube.com/watch?v=s2am3kbL1n4 SLS 3d printer prototype
[14:17:51] <Tecan> (s2am3kbL1n4) "SLS 3d printer prototype" by "xanxys0" is "Tech" - Length: 0:01:59
[14:18:25] <L84Supper> it's slower than using galvos
[14:18:35] <L84Supper> but maybe you already have the parts
[14:19:07] <WalterN> I dont have the parts for anything
[14:19:31] <WalterN> was going to build it from scratch
[14:20:13] <L84Supper> https://www.youtube.com/watch?v=uu6Lemm_Dts using a bluray laser
[14:20:14] <WalterN> well, with as much off the shelf stuff as possible I guess... things such as linuxCNC
[14:21:01] <L84Supper> we'll be submitting patches for linuxcnc as time goes by
[14:21:27] <L84Supper> https://www.youtube.com/watch?v=iEUGbagf5-4
[14:21:56] <L84Supper> a plotter with a bluray laser vs spindle
[14:22:45] <L84Supper> sadara_afk: http://www.youtube.com/watch?v=gF4HG6v29UY Casio Laser projector burns some stuff
[14:22:46] <Tecan> (gF4HG6v29UY) "Casio Laser projector burns some stuff" by "pontiacg445" is "Tech" - Length: 0:07:33
[14:23:01] <WalterN> you mentioned a 100 watt laser, now you are linking stuff 100 times less powerful
[14:23:25] <L84Supper> same principals, just different lasers and powder
[14:23:39] <sadara> 100w is for metals
[14:23:54] <sadara> your talking sls plastic, right?
[14:24:16] <L84Supper> the casio uses 1.6w lasers, you can see it melt plastics
[14:24:27] <WalterN> well, yeah
[14:24:36] <WalterN> metal would be nice too..
[14:25:06] <WalterN> but not really necessary... first time and stuff
[14:25:20] <sadara> start with plastic
[14:25:25] <L84Supper> but 100w laser in a 1um dia spot vs 100um spot gets expensive
[14:25:34] <sadara> metal is harder than it sounds
[14:26:17] <WalterN> well yeah... just look at the rockwell rating of metal vs plastic
[14:26:19] <WalterN> much harder
[14:27:04] <sadara> metal is harder to sinter
[14:27:44] <L84Supper> oh well, back to work for me, i have lasers to grind
[14:28:48] <sadara> lanes?
[14:28:54] <sadara> lens's?
[14:29:25] <sadara> however the plural of lens is splelt
[14:29:35] <WalterN> L84Supper: so what kind of laser do I want for plastic... 10 watts or something?
[14:29:56] <sadara> WalterN: pick you materials first
[14:30:03] <WalterN> plastic?
[14:30:14] <sadara> what type of lastic?
[14:30:16] <WalterN> what kind of plastic... donno..
[14:30:33] <WalterN> whats the cheapest most common stuff?
[14:30:56] <sadara> What country are you in?
[14:31:00] <WalterN> USA
[14:31:33] <sadara> brb phone
[14:33:02] <sadara> read this -> http://code.google.com/p/lemoncurry/wiki/main
[14:33:35] <L84Supper> thats for dlp photopolymer
[14:33:52] <WalterN> sadara: I've read about the DLP process before
[14:34:08] <sadara> and your sure you want to go sls?
[14:34:24] <sadara> the UV method is much easier (you don't need a DLP
[14:35:02] <L84Supper> it all depends on that parts he needs to make
[14:35:23] <WalterN> I dont "need" to make anything :P
[14:35:24] <sadara> the UV method is cheaper too, he needs to start somewhere (materials cost more though)
[14:35:38] <sadara> "He" needs to pick a direction
[14:35:45] <sadara> :P
[14:36:00] <L84Supper> play with a bluray laser first
[14:36:05] <sadara> L84Supper: you grind lenes?
[14:36:11] <L84Supper> cheap galvos are <$200
[14:36:28] <L84Supper> blueray laser is what $20
[14:36:31] <sadara> or buy a 250 - 500mw laser on ebay
[14:36:35] <WalterN> hmm
[14:36:48] <sadara> he needs to know what wavelength he needs
[14:37:12] <sadara> (I , personally, would try and match the laser to the work I was doing
[14:37:19] <WalterN> can the DLP method use a normal LCD screen? where the screen is pressed up against the surface of the builting layer?
[14:37:24] <L84Supper> http://hightechdealz.com/product_info.php?products_id=33
[14:37:43] <L84Supper> for LCD you need a monchrome panel
[14:38:13] <sadara> L84Supper: do you grind lenes?
[14:38:39] <L84Supper> then for bottom up projection through a vat there are issues with unsticking the polymer
[14:38:39] <sadara> L84Supper: I have a cpl of mirrors I need made
[14:39:20] <L84Supper> sadara: not sure who i could recommend
[14:39:46] <L84Supper> I'm either working, sleeping or spending a few minutes here
[14:40:11] <sadara> the prices I got here in australia we, to put it bluntly, fucking riduculous
[14:41:08] <WalterN> well fudge
[14:42:12] <WalterN> L84Supper: what is the most common plastic powder used for SLS?
[14:42:25] <L84Supper> sadara: can't find them off the shelf?
[14:42:38] <L84Supper> ABS
[14:43:02] <WalterN> alright... ABS.. what kind of laser do I want for that?
[14:43:13] <sadara> L84Supper: no one seems to release catalogs over here any more, they are all ground to order, and therefor are all "custom"
[14:44:10] <sadara> L84Supper: in the states, what would I be looking at for a f2 100mm hyperboloid ? ( a very rough guess would be fine)
[14:44:14] <L84Supper> http://www.diytrade.com/china/pd/10541998/GPolymers_SLS_selective_laser_sintering_PA12_Powders.html
[14:45:04] <WalterN> that is nylon?
[14:45:45] <JT-Shop> http://en.wikipedia.org/wiki/Nylon
[14:45:52] <WalterN> 100kg minimum order... hah.. how much would that cost?
[14:45:52] <L84Supper> http://www.rpsupport.co.uk/laser_sintering_materials.php
[14:46:08] <L84Supper> few $ /kg
[14:46:50] <L84Supper> WalterN: lots of suppliers
[14:47:13] <L84Supper> you just need to find one that will sell you a few lbs for testing
[14:47:21] <WalterN> yeah
[14:47:34] <WalterN> herm
[14:47:49] <L84Supper> http://www.topglobalmarket.com/rubber/pa12-powder-resin-for-selective-laser-sintering-sls-polyamide-powder-for-additive-manufacturing-and-rapid-prototyping-rp-p138168.html 10KG
[14:53:03] <WalterN> L84Supper: what kind of material should I start with?
[14:55:12] <L84Supper> you could grind your own powder as well
[14:55:34] <L84Supper> it just won't be as consistent as something made for sls
[14:57:35] <WalterN> so no material suggestions?
[14:58:13] <L84Supper> pa12 is cheap and low temp
[14:58:32] * WalterN looks it up
[14:59:07] <L84Supper> but some powder coating
[15:00:00] <L84Supper> http://www.harborfreight.com/16-oz-powder-coat-paint-white-93307.html
[15:00:09] <L84Supper> $5/lb
[15:00:25] <WalterN> what?
[15:00:35] <FinboySlick> L84Supper: I'm compiling the double-hasher for artix-7 now... I think it's too big.
[15:00:39] <L84Supper> powder coat
[15:01:04] <WalterN> what about powder coat... use that instead of pa12?
[15:01:38] <L84Supper> WalterN: yeah, it's cheap and easy to melt
[15:01:47] <WalterN> hmm
[15:02:03] <WalterN> alright
[15:02:06] <WalterN> I guess
[15:02:10] <WalterN> ohhhhhh
[15:02:13] <WalterN> hey
[15:02:23] <WalterN> I could make rocket engine stuff too
[15:02:29] <L84Supper> there are thermoplastics and thermosets, start with the thermoplastics
[15:03:13] <WalterN> what kinds of materials are each?
[15:03:22] <L84Supper> but $5/lb at harbor Freight is tough to beat for small volumes
[15:03:35] <L84Supper> epoxy is a thermoset
[15:03:39] <WalterN> ah
[15:03:45] <WalterN> ok
[15:04:08] <WalterN> UHMW and acrylic would be a thermoplastic?
[15:04:18] <L84Supper> nylon or polyester is thermoplastic
[15:05:12] <L84Supper> UHMW is just ultra high molecular weight, it can be a set or plastic
[15:05:31] <L84Supper> you can also use a thermoset it's just that you can't remelt them
[15:05:45] <sadara> I'm concidering doing this now as well
[15:05:55] <WalterN> sadara: lol
[15:06:24] <L84Supper> check ebay
[15:06:59] <WalterN> check ebay for what?
[15:07:07] <L84Supper> power coat
[15:07:15] <WalterN> oh heh
[15:07:24] * WalterN flails
[15:07:24] <L84Supper> powder coat even
[15:07:53] <WalterN> L84Supper: is an 18" box decent sized for something like this?
[15:08:04] <L84Supper> WalterN: sure
[15:08:08] <WalterN> I'm not even sure what most commercial sized ones are
[15:08:25] <L84Supper> FinboySlick: yeah, the numbers just don't seem to be adding up
[15:08:36] <WalterN> the only one I remotely looked at was a metal based one that cost $750,000 to make
[15:08:44] <WalterN> erm
[15:08:45] <WalterN> to buy
[15:09:13] <FinboySlick> L84Supper: You played with it too? Or did you just mean performance/price numbers?
[15:09:29] <L84Supper> FinboySlick: performance/price numbers
[15:10:30] <FinboySlick> L84Supper: They actually might. Artix apparently hits 600+Mhz.
[15:10:32] <L84Supper> WalterN: http://www.additive3d.com/com3_lks.htm Selective Laser Sintering and related powder-based technologies
[15:10:45] <L84Supper> FinboySlick: than that might work
[15:10:50] <L84Supper> if it fits
[15:11:45] <FinboySlick> L84Supper: I'm struggling to learn enough for that part. Might help if there are built-in functions that the spartan doesn't have.
[15:12:02] <FinboySlick> Like extra adders or multipliers.
[15:12:33] <L84Supper> sadara: FFF and FDM are now GGG or G3 (glorified glue gun)
[15:13:53] <sadara> reprap != good
[15:14:39] <WalterN> yeah
[15:14:45] <WalterN> I looked at that last night
[15:14:51] <WalterN> no ballscrews
[15:14:56] <WalterN> automatic fail
[15:15:18] <sadara> WalterN: not true, there are better alternitives to ballscrews
[15:15:40] <sadara> the reprap is a fail because it is an extruder
[15:15:43] <andypugh> linear motors, for example?
[15:15:47] <L84Supper> it was nice 20 years ago, but there is so much new tech that makes much nicer parts and much faster
[15:16:03] <sadara> linear motors are one
[15:16:43] <sadara> depends on the application, I wuld be fine with a belt drive for a reprap or extruder
[15:16:47] <L84Supper> now GGG isn't bad for everything, some materials are extruded well and it makes sense in some cases along with other tech
[15:17:26] <sadara> I wouldn't use a timing belt though, I would use normal belts and a glass encoder
[15:17:41] <WalterN> L84Supper: so... I'm confused... with one of these lenses... http://www.iiviinfrared.com/CO2-Laser-Optics/scanning-laser-system-optics.html do I not need to change the spot focust, cause it does that automatically based on where the light comes in at what angle?
[15:17:59] <sadara> http://www.ebay.com.au/itm/940nm-3W-Fiber-Coupled-Laser-Semiconductor-Diode-Fiber-CoupledL-aser-w-h-PSU-/251081459043?pt=LH_DefaultDomain_0&hash=item3a759f0563
[15:18:15] <sadara> ^^ may be a better option
[15:18:22] <sadara> esp if you are using steppers
[15:18:51] <L84Supper> WalterN: I have to go but sadara has the info you need
[15:19:32] <L84Supper> sadara: BTW are you up really early or late?
[15:19:53] <sadara> both, its four am,
[15:20:09] <L84Supper> when is your time change?
[15:20:12] <WalterN> so you havent beed to bed then
[15:20:18] <sadara> I will need sleep soon
[15:20:36] <WalterN> sadara: not till I get all necessary information
[15:20:40] * WalterN shakes fist
[15:20:44] <L84Supper> sadara: are you near Valen in Sydney?
[15:21:19] <sadara> I'm about 5000km to his west
[15:21:41] <L84Supper> near perth?
[15:22:18] <WalterN> waaaaait a sec
[15:22:20] <sadara> yeh, (sorry for the sarcasm, ppl seem to think australia is a tiny country with 1 or 2 small country towns)
[15:22:34] <DJ9DJ> gn8
[15:22:38] <WalterN> sadara: that ebay linky... the laser is attached to fiber optics?
[15:22:44] <sadara> yes
[15:22:48] <WalterN> so...
[15:22:53] <WalterN> thats pretty freeking awesome
[15:22:57] <andypugh> sumpfralle: Ar eyou involved with PyCAM> ]
[15:23:33] <sumpfralle> yes
[15:23:50] <L84Supper> sadara: there was a nanoparticle supplier near Perth
[15:24:18] <sadara> wtf, really?
[15:24:26] <sadara> nano copper?
[15:24:33] <andypugh> sumpfralle: I have been using it, and it seems to work: http://youtu.be/ZSLB-ue4CTI
[15:24:35] <Tecan> (ZSLB-ue4CTI) "Foundry Pattern Machining on my Mini-Mill" by "andy pugh" is "Tech" - Length: 0:03:34
[15:25:14] <L84Supper> sadara: TiO2 and Zn
[15:25:26] <andypugh> But the contoring algorithm is pretty slow, like an order of magnitude slower than the actual machining.
[15:25:53] <sumpfralle> yes - that is a pity
[15:26:15] <sadara> L84Supper: any idea on the name?
[15:26:28] <L84Supper> sadara: trying to recall
[15:26:39] <WalterN> sadara: you think three watts is enough?
[15:26:54] <sadara> nope
[15:27:29] <WalterN> you were just using that as an example?
[15:27:35] <sadara> but it is going to do 97% of what you will want to do with it (in plastic)
[15:27:54] <WalterN> then why would you say its not enough?
[15:27:54] <L84Supper> sadara: http://www.antaria.com/index.php?page=products
[15:27:57] <sadara> it's also MWIR
[15:27:57] <WalterN> lol
[15:28:08] <WalterN> what is MWIR?
[15:28:16] <sadara> medium wave ir
[15:28:28] <WalterN> oh
[15:28:30] <L84Supper> University of Western Australia
[15:28:32] <sadara> no UV, so it is a heat laser
[15:28:57] <WalterN> is that desirable?
[15:29:22] <sadara> I go to the lunchbar right next to that plase all the time, never new it was there
[15:29:32] <sadara> WalterN: it depands
[15:30:03] <sadara> It's not going to initiate UV cure compounds
[15:30:16] <WalterN> hmm
[15:30:45] <sadara> but it might cut very, very thin materials, and melt alsmost any plastic I can think of
[15:30:53] <L84Supper> sumpfralle: are the algorithms just slow or is it Python?
[15:32:08] <sumpfralle> probably the algorithms
[15:32:08] <sumpfralle> but I could not tell without rewriting them in a different language :)
[15:33:05] <L84Supper> sumpfralle: we looked into adding 5-axis support to pycam
[15:33:28] <sadara> what about 9 axis :) ?
[15:33:29] <L84Supper> but our customer let us off the hook by using NX CAM
[15:33:56] <L84Supper> but we'd like to see about helping speed things up and adding 5-axis support
[15:35:04] <WalterN> sadara: so should I consider the mirror method for directing the beam around? or should I just do stepper/servo motors (or something related) to direct the beam straight down on to the surface?
[15:35:11] <L84Supper> additive manufacturing needs its own version of CAM
[15:35:43] <sadara> WalterN: again, it depends on what you are trying to achive
[15:35:51] <WalterN> stuff
[15:35:57] <sadara> you can use mirrors on the axis as well
[15:36:02] <WalterN> yeah
[15:36:11] <WalterN> but you know what I mean
[15:37:15] <sadara> do you want to be able to do SLS, GGG (I like that acronym), cutting, polishing spraying welding and girls makeup with your machine? If so, you need to move the axis
[15:37:51] <sadara> if you want to do SLS, use the tilting mirror
[15:38:03] <L84Supper> acrylic nail powder will also sinter
[15:38:04] <WalterN> it might be nice to be able to engrave too...
[15:38:30] <WalterN> but thats pretty much the only thing I want to do
[15:38:59] <sadara> laser engraving, or mechanical?
[15:39:10] <WalterN> laser engraving
[15:39:25] <WalterN> I'd build a different machine otherwise
[15:39:27] <sadara> what material?
[15:39:46] <WalterN> donno... stainless, aluminum?
[15:40:24] <WalterN> say, 304/316, 6061...
[15:40:25] <sadara> ok you may want a 4 - 10W fibre coupled lasered
[15:41:42] <WalterN> and move the beam around so that it comes straight down?
[15:42:04] <sadara> no, fibre coupled, treat it like a 5 axis
[15:42:10] <WalterN> ..?
[15:42:40] <sadara> think of fibre coupled lasers like a water hose
[15:43:01] <sadara> you can point them in any direction, just don't kink the hose
[15:43:29] <WalterN> yeah, sure... but how is that 5 axes?
[15:43:53] <WalterN> thats only 2-3 axes I think?
[15:44:21] <WalterN> tilt one way, tilt the other, and maybe up and down
[15:44:22] <sadara> you can point it up or to the side
[15:45:02] <sadara> move right , move forward, move up, rotate left, rotate up
[15:45:29] <sadara> if you want to engrave something that is flat
[15:45:32] <WalterN> oh, so move it in X and Y, in addition to tilt?
[15:46:43] <sadara> move in x y and z, rotate in c and a
[15:47:17] <WalterN> yeah
[15:47:30] <WalterN> though the Z movement would be in the bed its self?
[15:47:42] <WalterN> (because laser sintering)
[15:48:00] <sadara> I should point out that most fibre coupled lasers have a focus around 20mm in frount of the objective lens
[15:48:09] <sumpfralle2> L84Supper: 5-axis geometry is a sphere of wisdom that is completely new for me. But if you provide the algorithms then it will surely work out with pycam
[15:48:36] <sadara> I, personally, would move the laser itself, in addition to the bed
[15:48:38] <L84Supper> sumpfralle2: we will have 2 full time devs this summer to help with it
[15:48:57] <WalterN> sadara: so that would be 6 axes...
[15:49:20] <WalterN> if moving the laser up and down in addition to the bed moving up and down
[15:49:26] <L84Supper> sumpfralle2: not every customer can afford $35K for a full NX CAM or even $22K for Mastercam 5-axis
[15:49:55] <sumpfralle2> L84Supper: of course - I agree
[15:50:09] <L84Supper> sumpfralle2: we'll join the ml
[15:50:10] <sumpfralle2> L84Supper: who is "we"?
[15:50:14] <sumpfralle2> fine!
[15:50:38] <sumpfralle2> (just curious)
[15:50:55] <sadara> I would do xyz, plus the bed (4 so far) and a addon forth and 5th (google image search for "4th axis")
[15:51:40] <WalterN> is there a lense I could get to extend the focus length?
[15:52:10] <sadara> you would swap out the SLS bed, to add the 4+5 axis
[15:52:42] <WalterN> 1" is not much, esp if there is going to be stuff going on between the laser and the top of the part being made
[15:54:09] <WalterN> wait, why would I want tilt if it is already moving around in X and Y?
[15:54:27] <sadara> how do you engrave a pen?
[15:54:53] <WalterN> in a C-axes lathe? :-x
[15:55:16] <WalterN> I see what you are getting at though
[15:55:29] <WalterN> at least now I do :P
[15:56:38] <sadara> this is 4 axis -> http://www.youtube.com/watch?v=dFLqQ-yn3gk&playnext=1&list=PLED77849FE6633EF0&feature=results_main

[15:58:43] <findux> hi there . how can i compile new chanced genhexkins.c file ? I always used linuxcnc from live cd. but not used to install.
[15:59:28] <WalterN> sadara: I could add the tilt stuff later too.. hmm
[15:59:40] <sadara> yes
[15:59:54] <WalterN> anyway
[15:59:56] <WalterN> http://www.ebay.com/itm/Laser-Diode-8W-8-Watt-8000mW-915nm-Fiber-Coupled-100um-Multimode-Pump-NEW-/110959792691?pt=LH_DefaultDomain_0&hash=item19d5b81233
[15:59:59] <WalterN> is that good?
[16:00:04] <WalterN> wait
[16:00:07] <WalterN> hmm
[16:01:13] <WalterN> no lense?
[16:01:35] <WalterN> or power supply
[16:02:31] <sadara> no output lens, tht makes it a bit difficult to work with, as the low NA means the beam will spread very fast
[16:03:19] <WalterN> what would a good lense be for that?
[16:04:43] <noob123> Have anyone used those cheaps CNC from ebay?? CNC 3020 or CNC 3040 or any other one from ebay ??
[16:07:47] <sadara> WalterNate: you need to figure out what you want to do, and do a little more research
[16:08:59] <WalterN> I want to burn stuff with lasers :P
[16:21:07] <Nick001-Shop> Is there a sample ini & hal file for a closed loop stepper setup?
[16:58:23] <mrsun> need to make my own "ball end" cutter to cut ball holes :/ .. how the heck :P
[16:59:06] <pcw_home> basically a closed loop stepper system is set up exactly like a standard servo system
[16:59:08] <pcw_home> except the output of the PID component sets the stepgen rate instead of a analog, pwm etc output
[17:13:32] <Nick001-Shop> I generated this with stepgen and put index into the ini - how do I get a pid list in there besides cut & paste?
[17:15:52] <Nick001-Shop> the stepper moves to find home(index) but doesn't see index - what am I missing? I can see index in hal config OK
[17:28:50] <pcw_home> The index logic is independent of whether a servo drive or stepgen in velocity mode is used
[17:29:40] <pcw_home> so if index does not work its unrelated to the step motor vs servo motor aspect
[17:31:07] <pcw_home> you do have to set the stepgen into velocity mode
[17:31:12] <cradek> if you mean you started with a stepconf-generated config, that's running stepgen in position mode, and index homing will certainly not work
[17:31:41] <AR_> anyone on here use an external motion controlelr instead of direct parallel port connection?
[17:32:44] <pcw_home> start with a servo configuration is what I tried to suggest at first
[17:36:43] <pcw_home> AR_: Usually LinuxCNC _is_ the motion controller so gets along better
[17:36:45] <pcw_home> with simpler external devices.
[17:37:26] <AR_> yeah i just wondered if there were any external motion controllers that worked with linuxcnc
[17:38:45] <Nick001-Shop> how do you set the stepgen into velocity mode?
[17:40:13] <Nick001-Shop> not finding this info in the forum
[17:46:38] <Nick001-Shop> also, is this something to use 5i20 or just the parport?
[17:50:28] <pcw_home> man stepgen
[17:50:49] <pcw_home> (or man hostmot2)
[17:55:30] <AR_> tired of fixing my chinese tb6560 3 axis driver
[17:55:37] <AR_> what's a cheap better alternative
[17:55:40] <AR_> ?
[17:55:57] <AR_> Leadshine M542 or Gecko G251x
[17:58:56] <Tom_itx> those seem to come highly recomended
[17:59:17] <andypugh> findux: Are you still there? Did you get your answer?
[17:59:47] <findux> yes please
[18:00:09] <andypugh> You ought to be able to compile genhexkins with comp.
[18:01:01] <andypugh> Look at section 12 here: http://www.linuxcnc.org/docs/html/hal/comp.html
[18:01:35] <andypugh> You want to compile and install C-code, to it would just be sudo comp --install genhexkins.c
[18:02:41] <andypugh> comp isn't really intended for kins files, but by a happy accident hal modules and kins modules live in the same place, and are the same things (kernel objects)
[18:02:49] <findux> I read ' *SOLVED* Recompiling genhexkins ' in the forum. but I do not understand exactly what I need
[18:03:13] <andypugh> What happens if you try sudo comp --install genhexkins.c
[18:05:52] <findux> I receiver something like this massage'WARNING: "pmRpyMatConvert" [/tmp/tmpvWVdx8/genhexkins.ko] undefined!'
[18:06:43] <findux> WARNING: "pmRpyMatConvert" [/tmp/tmpvWVdx8/genhexkins.ko] undefined! WARNING: "hal_init" [/tmp/tmpvWVdx8/genhexkins.ko] undefined!

[18:07:20] <andypugh> OK, that probably means that you need the source headers. Do you have a git clone of the source?
[18:07:35] <t12> mm
[18:07:36] <t12> linking?
[18:07:54] <t12> oh thats just weird output format
[18:08:21] <andypugh> findux: Those are all warnings, it _might_ still work.
[18:09:36] <findux> I received an error when I run the software
[18:09:44] <findux> errors
[18:09:55] <andypugh> OK, so you do need the headers.
[18:10:04] <L84Supper> AR_: what keeps on breaking?
[18:10:11] <andypugh> How dd you get genhexkins.c ?
[18:10:18] <AR_> nothing really keeps breaking
[18:10:21] <AR_> they are just shitty
[18:10:43] <L84Supper> yeah, I have a few of the single axis, boy are they noisy
[18:10:51] <findux> I cahanged only genhexkins.h some numerical value
[18:11:01] <AR_> the only things that have broke so far is one of the TB6560 chips and a 74HC chip
[18:11:05] <AR_> both my fault
[18:11:18] <AR_> but i think there are some other things going on it
[18:11:34] <L84Supper> yeah 0 protection against just about anything
[18:11:40] <AR_> ya
[18:11:41] <andypugh> findux: Do you only have genhexkins, or do you have the full LinuxCNC source?
[18:11:49] <Felix29> what do you think about the tb6560? is it worth changing?
[18:11:55] <AR_> i'm thinking of buying a couple Leadshines
[18:12:02] <AR_> $44 from china
[18:12:29] <AR_> when i bought the 3 axis tb6560 board it was over $75! lol
[18:14:27] <findux> first I have tried run-in-place method. didn' work, after I heve tried this line 'sudo comp --install genhexkins.c ' in source directory.
[18:14:47] <findux> didn't work
[18:16:34] <L84Supper> I've been thinking about a 3-axis board with a $5 arm cortex a9 soc on a board for ~$75
[18:16:54] <andypugh> You probably need to be in the actual src/ directory. So try sudo comp --install emc/kinematics/genhexkins.c
[18:17:03] <L84Supper> with enough ram for linuxcnc and a sd card
[18:18:11] <Nick001-Shop> pcw_home - can I use hm2-stepper with 5i20 and how do I set it to velocity mode and do I need to use a stepper driver like 251x?
[18:18:35] <findux> yes I downloaded src file from git
[18:19:07] <andypugh> Which directory were you in when you issed the "comp" command?
[18:21:26] <L84Supper> wow $3 3W 410nm led's from China, waiting for my eyes to recover....... yellow spots
[18:23:27] <findux> extracted *.tar.gz. file the following directory '/home/myownuser/myowndirectory' than I tired
[18:24:34] <andypugh> Is your modified genhexkins in src/emc/kinematics ?
[18:25:18] <findux> no
[18:26:27] <andypugh> It might need to be, I am not sure
[18:27:15] <findux> I did exactly this .' cd /home/myownuser/myowndirectory/build/src/emc/kinematics/' than this line 'sudo comp --install genhexkins.c'
[18:28:51] <andypugh> Hmm.
[18:32:22] <andypugh> findux: I am creating a virtual machine to experiment on.
[18:33:35] <findux> I received ebove errors after I think existing genhexkins.ko changed and didn't work
[18:35:43] <WalterN> would this be a good laser for laser sintering rapid prototyping machine? http://www.ebay.com/itm/30-Watt-Coherent-Laser-w-Heat-Sink-Water-Cooling-Module-FAP800-L-30W-/130843032047?pt=LH_DefaultDomain_0&hash=item1e76da39ef
[18:37:15] <L84Supper> looks good, i have to check the wavelength
[18:37:30] <WalterN> http://www.coherent.com/downloads/FAP800series_DSFinal.pdf is the data sheet I think
[18:38:11] <L84Supper> short IR ~800nm
[18:38:54] <WalterN> I'm wondering what that other thing is
[18:39:01] <L84Supper> 805-811nm
[18:39:52] <WalterN> the LST400IRW2
[18:40:07] <WalterN> NM laser products
[18:40:36] <L84Supper> http://www.nmlaser.com/
[18:40:49] <WalterN> yeah, looking at that
[18:41:09] <WalterN> shutter?
[18:41:15] <L84Supper> yeah
[18:41:30] <WalterN> what does that do?
[18:41:57] <WalterN> turns a continious laser into pulsed? XD
[18:42:28] <L84Supper> http://www.nmlaser.com/pdfs/LST400Specs.pdf
[18:42:38] <L84Supper> safety interlock
[18:43:11] <L84Supper> there an aperture on the other side of that unit
[18:43:22] <L84Supper> that is where the laser would exit
[18:43:35] <WalterN> oh yeah
[18:43:44] <WalterN> a little rubber thing it seems
[18:43:58] <L84Supper> from a distance
[18:44:18] <WalterN> think there is a lense on it?
[18:44:27] <WalterN> a focusing lense
[18:44:38] <L84Supper> don't know
[18:44:46] <L84Supper> it was part of something
[18:45:54] <WalterN> if it does not... what kind of lense would I want?
[18:48:09] <L84Supper> coherent still makes that unit
[18:48:18] <L84Supper> check the data sheets and call them
[18:48:27] <WalterN> hmm
[18:48:51] <WalterN> 807nm wavelength... is that still in the visable spectrum?
[18:49:07] <WalterN> its pretty close anyway
[18:50:29] <L84Supper> short IR
[18:52:20] <WalterN> is that a good price?
[18:54:06] <andypugh> fundux: You might have to recompile all of Linuxcnc to get the new genhexkins to work.
[18:54:40] <andypugh> findux: You might have to recompile all of Linuxcnc to get the new genhexkins to work.
[18:54:47] <findux> ok .

[18:55:10] <L84Supper> it's a bargain
[18:55:40] <WalterN> think I should get it, and figure out what I need when it arrives?
[18:56:11] <findux> can you give me link how can I recompile all of linuxcnc
[18:56:21] <andypugh> findux: "cd src" followed by "./autogen.sh" then "./configure --prefix=/usr" then "make" then "sudo make setuid"
[18:57:27] <findux> ok I 'm trying
[18:58:03] <andypugh> More details here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC#Resolving_outstanding_build_dependencies
[18:58:27] <L84Supper> WalterN: just don't stare at it :)
[18:58:44] <WalterN> L84Supper: heh... so I take that as a yes?
[19:00:35] <andypugh> For that price, I am tempted, and I don't even need a laser.
[19:00:43] <WalterN> yeah
[19:01:01] <L84Supper> <-- back at work, sorry
[19:01:26] <andypugh> WalterN: You should be able to re-eBay it at a profit anyway..
[19:01:40] <WalterN> well
[19:01:51] <WalterN> if I get it and the laser is working... I'm so keeping it
[19:02:11] <WalterN> because at the very least I can say I have a BSL (big scary laser)
[19:02:15] <L84Supper> some of the sellers end up with surplus and don't really know what it is or is worth
[19:02:38] <L84Supper> you can always strap it on a shark for photo ops
[19:03:32] <WalterN> it could be that they have to pull the laser out every 5 years or whatever and get it replaced
[19:04:38] <andypugh> WalterN: If you do get it, then I think there _might_ be a safety clip shorting the laser power inputs.
[19:05:03] <r00t4rd3d> http://imgur.com/a/RaBXi
[19:05:54] <WalterN> r00t4rd3d: so much effort put into cosmetics
[19:06:33] <WalterN> also, https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTkqL69ZwfUjoYZaGRYRQSW3L-OzQDxZrprEZK2IlrvSr93ggKtRA
[19:07:48] <WalterN> L84Supper: am I reading this data sheet correctly and seeing that there is 25 watts in the laser beam?
[19:08:52] <andypugh> findux: Sorry old chap, but I need to go now. Good luck.
[19:10:19] <findux> ok thanks .
[19:11:03] <WalterN> dude
[19:11:14] <WalterN> I'm looking at some of the other stuff this guy has
[19:11:16] <WalterN> http://www.ebay.com/itm/20-NEW-Cornell-Dubilier-Capacitors-46000-uF-50-Volts-VDC-Screw-Top-50v-/130738754289?pt=LH_DefaultDomain_0&hash=item1e70a312f1
[19:12:06] <WalterN> 46,000uf capacitors
[20:41:06] <L84Supper> WalterN: if it's from the "The Value Goose" its gotta be good!
[20:41:42] <WalterN> L84Supper: so I should quit trying to talk myself out of it and get that laser?
[20:44:08] <L84Supper> I have no desire to control you or tell you what to do :)
[20:44:22] <WalterN> haha
[20:44:35] <PetefromTn> Sweetness!!
[20:44:43] * Valen knows some people who wouldn't mind bossing you around
[20:44:43] <PetefromTn> Helo all...
[20:44:48] <Valen> you like whips right?
[20:45:08] <L84Supper> howdy PetefromTn
[20:45:18] <PetefromTn> How do...
[20:45:31] <L84Supper> Valen: most people under 30?
[20:45:40] <Valen> lol
[20:45:44] * Valen left that club
[20:45:48] <Valen> last week :-<
[20:45:52] <WalterN> ouch
[20:46:00] <L84Supper> welcome old man
[20:46:22] <PetefromTn> So we all talking LinuxCNC or what?
[20:46:29] <L84Supper> yes
[20:46:38] <Valen> why would we talk about that here?
[20:46:44] <WalterN> crazy
[20:46:49] <PetefromTn> Wonderin if my pal Billy is in here...?
[20:46:52] <WalterN> I just wanted to talk about lasers
[20:46:54] <Valen> seesh, kids these days
[20:46:55] <Valen> ;-P
[20:47:13] <PetefromTn> LOL this is cool. Have not been on a chat like this for years...
[20:47:20] <L84Supper> Valen: somebody from the other side of that island you live on was here a few hours ago
[20:47:34] <Valen> wow that must have been early (or late)
[20:47:43] <L84Supper> he was up late
[20:47:53] <L84Supper> Perth
[20:47:59] <PetefromTn> Who is the resident Ladder logic GURU?
[20:48:07] <Valen> as of yesterday thats 4 hours behind
[20:48:24] <L84Supper> wow, clock went back?
[20:48:31] <Connor> PetefromTn: Yup. I'm here.
[20:48:57] <PetefromTn> Hey man HOWYA doing? I just texted ya.... Finally found my way here LOL..
[20:49:07] <gry> PetefromTn: there is a bill1123 but I'm not totally sure it's who you're looking for
[20:49:31] <PetefromTn> Nope its my boy Connor, I think I blew his cover tho LOL...
[20:49:55] <PetefromTn> How do you respond to a specific person like that?
[20:49:56] <Connor> PetefromTn: Yea.. Just got your text and email.. I was away from computer eating Dinner.. left my phone in the office.. Just set back down to finish up some stuff for a client.
[20:50:09] <WalterN> this is getting too scary for me... I'm just going to buy this 30watt laser here
[20:50:09] <Valen> yeah daylight savings ended
[20:50:19] <PetefromTn> No worries man, you have been a great help to me this weekend already. P
[20:50:51] <Connor> PetefromTn: Just start typing their name and hit tab to complete it.. The client will "beep" at them letting them know someone said something with their handle in it..
[20:51:02] <PetefromTn> Connor: Cool...
[20:51:29] <PetefromTn> you'll have me all geeked out before ya know it man...
[20:51:34] <WalterN> I dont think most beep.. most can be set up to beep though
[20:51:48] <PetefromTn> How do you set it, that would be neat...
[20:51:51] <L84Supper> WalterN: http://www.3ders.org/articles/20120202-low-cost-and-open-source-sls-wax-3d-printer.html
[20:52:17] <Valen> btw you can make wax powder *really* easily ;->
[20:52:20] <WalterN> L84Supper: yeah, I saw that last night...
[20:52:21] <Valen> if extremly messy
[20:52:46] <WalterN> Valen: heated pressure washer?
[20:52:59] <Connor> mIRC and Pidgin both beep... not sure about other clients..
[20:53:12] <Valen> nah, carby
[20:53:28] <Valen> pot of hot wax, tube leading out of it, then blow compressed air over the top
[20:53:36] <PetefromTn> Connor: I downloaded Quassel first one I found that looked okay..
[20:53:39] <Valen> superfine wax powder
[20:53:48] <L84Supper> http://3dprintingindustry.com/2013/02/22/the-first-3d-printed-polymer-implant-to-receive-fda-approval/
[20:53:55] <Valen> will handily fill the workshop in about half a second
[20:53:56] <L84Supper> uses PEEK powder
[20:54:16] <Connor> PetefromTn: Never used that one. I use Pidgin since I'm on Ubunutu. mIRC was what I used when on Windows.. but.. what ever works is good. :)
[20:54:40] <WalterN> HexChat (a fork of Xchat) is my favorite
[20:54:53] <Valen> I use pidgin
[20:55:13] <Valen> though with MSN going away and no real way to integrate with skype :-<
[20:55:25] <Connor> I use Pidgin for AIM and other MSN chat too.
[20:55:41] <Connor> and it supports google+
[20:55:41] <Valen> somebody should make a MSN "server"
[20:55:46] <PetefromTn> Connor: just found it apparently can use sounds notifications but you need the sound byte to use it. Apparently none in there LOL...
[20:56:15] <Connor> Just copy and ol .wav file into it..
[20:56:47] <gry> PetefromTn: settings has a notification panel in Quassel, it can beep too
[20:56:49] <Connor> PetefromTn: On the ladder stuff.. that about the tool changer? because, remap might work good for it too...
[20:57:08] <gry> PetefromTn, (ask in client channel and they'll help to tune it somewhat)
[20:57:11] <PetefromTn> Connor: Gonna work on this Cincinatti arrow some more tomorrow trying to get the Y axis motor installed. Gonna try to use that Halscope for tuning again...
[20:57:43] <PetefromTn> What is client channel?
[20:58:00] <PetefromTn> Don't have any .wav files...
[20:58:25] <Connor> PetefromTn: probably the IRC channel for the program...
[20:58:58] <Connor> Looks like a #quassel channel exists on this server...
[21:00:28] <jdhFromTN> hmm
[21:00:33] <Connor> jdhFromTN: Smart A$$. :)
[21:01:04] <Connor> I thought it was jdhNC ? :)
[21:01:10] <jdh> is it?
[21:01:13] <PetefromTn> LOL...okay just downloaded a .wav beep. installing...
[21:01:15] <Connor> not know.. but it was..
[21:01:21] <Connor> a long time ago.
[21:01:31] <jdh> jdh was registered so I couldn't use it.
[21:01:34] <jdh> probably by me.
[21:01:42] <jdh> -NickServ- This nickname is registered. Please choose a different nickname, or
[21:01:47] <PetefromTn> jdh: you stealin' my thunder...!!
[21:01:57] <jdh> I seem to have forgotten my password again though
[21:02:04] <Connor> yea. I've had Connor on this server since around 98 maybe ?
[21:02:40] <jdh> heh, I actually avoided this network while lilo was around
[21:03:12] <PetefromTn> Connor: whaddya mean remap?
[21:04:03] <PetefromTn> whatsit mean when the username has a little clock on it? Days numbered or something? LOL
[21:04:04] <Connor> Remap is a module for hal that lets you remap G commands to run programs If I remember correctly. http://www.linuxcnc.org/docs/devel/html/remap/structure.html
[21:04:25] <Connor> Could be people who are idle ?
[21:04:39] <PetefromTn> How ya go idle?
[21:04:43] <jdh> Pete: I lived in .tn.us for 30ish years
[21:04:45] <Connor> don't type for a while. :)
[21:05:05] <PetefromTn> jdh: Oh Im so sorry LOL...
[21:05:20] <jdh> Pete: I got better about 16 years ago.
[21:05:47] <jdh> evidently I have to go bck in may for a wedding though.
[21:05:48] <Connor> So, the question is, if remap is stable enough now for tool changers.. I think it is. and will be seamless when added into your setup.
[21:05:49] <PetefromTn> Ooh thats good.... I'm trying to prep my house so I can move back to FLorida and sit on the beach.
[21:06:15] <PetefromTn> jdh: cool man look me up...
[21:06:34] <PetefromTn> Honestly I think ladder is the way to go here....
[21:06:42] <Connor> PetefromTn: jdh is a fellow G0704 owner (same mill as mine) He got it around the same time I did..
[21:06:52] <PetefromTn> Whose the resident Ladder logic guru
[21:07:04] <jdh> jt
[21:07:09] <PetefromTn> Well apparently no beep...dunno what I did wrong.
[21:07:21] <Connor> Dunno. jt and skunkworks probably.
[21:07:26] <jdh> I do AB and GE/Fanuc at work though
[21:08:21] <Connor> I know remap can handle everything though.. it basically maps out the G-command to a external program and we can do everything we need in it.
[21:08:23] <PetefromTn> What's AB?
[21:08:38] <Connor> I know little about ladder
[21:08:46] <jdh> allen-bradley
[21:09:09] <PetefromTn> Ladder logic can handle all the If/then stuff which is paramount for safety here I think but I don't know JS about it.
[21:09:22] <PetefromTn> Oh Allen Bradley.
[21:09:35] <Connor> Yea. remap can too.. and allot more.. such as storing variables and counting etc etc.
[21:09:36] <PetefromTn> That's the spensive stuff...
[21:10:50] <Connor> it could also keep track of stuff like how many times a tool was used.. by storing it in a external file every time that tool was used.
[21:11:46] <PetefromTn> Oh really? That is something I would think could come in real handy. Lee uses something OTHER than Ladder logic and not sure exactly what just yet.
[21:12:02] <Connor> Would be Remap. I think that's the only other way.
[21:12:15] <PetefromTn> I will logon to this when I am working on the machine that way when I have questions I can ask away.
[21:12:25] <Connor> Lets you mix Gcode with python programming to do everything you need.
[21:13:10] <PetefromTn> Dunno really he said he has something that uses G code in a seperate program somehow. Wish he was on here. Dunno maybe he is apparently there are 120 other CNC junkies in attendance right now...
[21:13:39] <Connor> Do you know his Handle on IRC ?
[21:13:43] <PetefromTn> I see Chris Radek is in here... He's got some heavy iron retrofitted...
[21:14:02] <PetefromTn> Nope just his Email dunno if he is even on IRC...
[21:15:05] <jdh> you can use m100-m199, but you would have to insert that yourself vs. just M6?
[21:15:14] <PetefromTn> His Email is Lomach and I don't see anything like that in the list right now...
[21:15:57] <PetefromTn> Really want this monster to run exactly like it did when new so that precludes anything but M6 codes...
[21:16:33] <PetefromTn> Are we the only people talking in here right now? All those other 120 folks are awful quiet unless I am missing how to hear them...
[21:16:42] <jdh> http://www.youtube.com/watch?v=bSXR3FsN0EE
[21:16:43] <Tecan> (bSXR3FsN0EE) "Linuxcnc retrofit of a Cincinnati Arrow 500" by "Lee Osborne" is "Tech" - Length: 0:00:46
[21:17:14] <PetefromTn> Tecan: Yup that's him... Sweet looking machine all stealthy like that No?
[21:17:30] <Tecan> hmmm
[21:17:40] <PetefromTn> That is the EXACT same machine I have... Are you Lee?
[21:17:48] <Tecan> Leecan ?
[21:18:14] <PetefromTn> Tecan: Is that his IRC name?
[21:18:46] <PetefromTn> Sure would be nice if he was on here as calling him on the phone in England last time cost me a pretty penny LOL...
[21:18:58] <Connor> PetefromTn: Skype
[21:19:41] <PetefromTn> Connor: yeah we actually talked about doing that.. If I need to I will...
[21:19:44] <Connor> PetefromTn: Honestly, let me just write it up with remap. Because I'll end up using 80% of it for my tool changer when I get it built.
[21:19:57] <Connor> It'll use the M6 tool change command.
[21:20:06] <PetefromTn> Why don't you want to use the ladder logic?
[21:20:27] <PetefromTn> oh and what is 3voiced?
[21:20:59] <Connor> I don't know ladder and you can do allot with more with remap.
[21:21:34] <PetefromTn> I favorited the link about remap. Gonna read it some tomorrow...
[21:22:05] <Connor> Okay.. it's mix between G-Code and Python. which lets you do ANYTHING just about.
[21:22:11] <Connor> Ladder is a bit more old-school
[21:22:22] <L84Supper> anyone ever see a flexible encoder strip that could be applied to a conveyor belt, need ± 50 µm (0.002")
[21:22:27] <PetefromTn> Yeah I LIKE old school....usually means it works good.
[21:24:01] <Connor> Hmm.. I can't load the Ladder Editor on my Simulator
[21:24:13] <Connor> and andy is already logged off..
[21:25:01] <PetefromTn> Andy who?
[21:25:39] <Connor> Andy Pugh
[21:25:44] <Valen> L84Supper: perhaps a magentic one?
[21:26:03] <PetefromTn> Big John sent me a simulation setup with a ladder logic of a toolchanger of some sort to look at and said to run it in simulation mode to see how it all works. Said it is not rocket science...
[21:26:12] <PetefromTn> Oh okay...
[21:26:25] <PetefromTn> He's in England so it must be getting late over there I suppose.
[21:27:00] <PetefromTn> ooh Lookey we got Fox Mulder in here, from the X files. Cool
[21:27:25] <PetefromTn> Why does it seem like I'm doing all the talking LOL...
[21:27:45] <Connor> It comes in waves. :)
[21:27:59] <Connor> Late Sunday it's pretty dead most of time.
[21:28:22] <Connor> and most across the pond are asleep or no up yet.
[21:28:41] <PetefromTn> True...
[21:28:52] <PetefromTn> I see Pete from mesa...
[21:29:04] <Connor> Only reason I'm on is because I'm working late.. :(
[21:29:15] <PetefromTn> You call this working LOL
[21:29:36] <Connor> I'm working in the other window. :)
[21:31:20] <WalterN> L84Supper: well, I bought that laser... $322 shipped
[21:31:38] <PetefromTn> Gonna finish machining the little brass terminals for the power leads to the Y axis motor tomorrow morning so I can finally stick that monster in there. Got lots of cleaning of sludge off the sheetmetal covers then I can put that all back on.
[21:32:11] <Connor> Cool.
[21:32:15] <PetefromTn> I also need to try to figure out how to wire up that spindle drive. Gonna start working on that bad boy tomorrow too...
[21:32:50] <Connor> That'll be fun. I'll see if I can send you the missing files and stuff you need to make the new control panel work..
[21:32:59] <PetefromTn> WalterN: Cool man now you're just like buck Rodgers...
[21:33:15] <WalterN> who is that?
[21:33:25] <PetefromTn> Nevermind...
[21:33:31] <Connor> ROFL
[21:33:51] <PetefromTn> Connor: okay man you'll probably have to tell me how to install them too since Im such a noob...
[21:34:12] <Connor> Yea. not a problem.
[21:34:40] <PetefromTn> Gonna hafta get one of those fancy wireless USB jobs so I can chat while I am tinkering...
[21:35:02] <Connor> Yea. or a long Cat5 cable and just plug it in..
[21:36:08] <PetefromTn> Just reading here about O words and python...
[21:36:52] <PetefromTn> What is NGC?
[21:37:07] <Connor> g file. NGC is the typical extension
[21:37:15] <Connor> err. g code file.
[21:38:26] <PetefromTn> Really, mine is usually .txt...
[21:42:12] <Valen> wires work
[21:42:18] <Valen> wireless is dodgy ;->
[21:42:28] <PetefromTn> Yeah but not nearly as cool LOL...
[21:42:30] <Valen> check device support list before purchasing wirless too
[21:42:56] <PetefromTn> Valen: where ya at Valen?
[21:43:22] <Connor> Down Under it looks like..
[21:43:28] <Valen> sydney au
[21:44:16] <PetefromTn> Wow no kidding... Got a friend in New Zealand who ALSO has a Cincinatti Arrow 500... he texts me sometimes and asks about my retrofit LOL
[21:44:43] <PetefromTn> What time is it In Sydney now?
[21:48:34] <PetefromTn> Connor: I am sure Lee would share his Toolchanger setup with me he has been very helpful so far. Dunno if it is in the Hal and INI files doubt it but since I really don't know how he is doing it that is not surprising. He does say that his machine has now performed thousands of toolchanges without issue tho so whatever he is doing is working .
[21:49:15] <Connor> PetefromTn: They'll be separate.. if he's willing to share that'll be a head start.
[21:49:58] <PetefromTn> Yeah I am sure it would... I think he will Ill ask him via email tomorrow.
[21:50:13] <PetefromTn> Oh and got a beep there scared the crap outta me LOL....
[21:50:28] <Connor> PetefromTn: ROFL
[21:50:49] <PetefromTn> Laugh it up fuzzball...
[21:51:36] <PetefromTn> What the hell kinda name is toastydeath?
[21:51:49] <Connor> I dunno, ask him. :)
[21:56:02] <PetefromTn> Connor: whaddya make of the metric labels on the inch settings issue we ran into on the build yesterday?
[21:56:46] <Connor> I need to send you 2 extra lines of code to paste into the button of the .axisrc file.
[21:59:31] <PetefromTn> Okay...
[22:11:02] <PetefromTn> Was just looking at that fourth axis you sent me links to...dayum I missed out on that one....sigh.
[22:11:15] <Connor> :(
[22:20:40] <Connor> PetefromTn: I'll keep my eyes out for another one.
[22:21:31] <PetefromTn> Cool man thanks... I may also just build one out of a rotab. Whatever I can get my hands on the least inexpensively the better.
[22:21:58] <PetefromTn> Dayum this forum is dead tonight. Really thought there would be a lot more questions and chatting.
[22:22:27] <Connor> That's why I idle in it all day while working.
[22:22:36] <jdh> it's late, sunday night. Hlaf the earth is off
[22:22:59] <Valen> its 1:00PM on a monday afternoon what are you talking about
[22:23:25] <jdh> the other half
[22:27:42] <PetefromTn> LOL....
[22:37:39] <PetefromTn> Well dudes, I'm ready to hit the sack here. Ill try to logon tomorrow while I tinker with the machine. Hopefully things will go well and I will make some more good progress. Cannot wait to see this monster make some parts...peace
[22:53:56] <r00t4rd3d> jdh, u in texas?
