[00:34:03] <archivist> ECA ! wikipedia was wrong
[00:34:38] <archivist> somebody on the internet was wrong
[00:39:09] <Jymmm> WHAT?! I read it on the internets, it can't be wrong!!!
[00:43:52] <archivist> some "person" had abbreviate Enhanced machine controller architecture to ECA despite the cited doc saying EMC
[01:06:58] <Jymmm> lol, dumbass
[01:08:05] <Jymmm> Gawd, i hate "buzz words"... architecture, framework, multimedia, etc
[01:40:29] <ds3> .
[01:40:30] <ds3> ~>
[01:40:34] <ds3> ~>
[01:41:03] <ds3> blah
[01:41:10] <Jymmm> ¿
[01:47:59] <Valen> ds3: are you trying to make sperms ?
[02:10:37] <Deejay> moin
[02:10:47] <Jymmm> You're fired!
[02:11:04] <Deejay> nope
[02:11:11] <Jymmm> Yep, too early!
[02:11:29] <Deejay> hehe
[04:20:41] <archivist_herron> that was very late, I was parked at a customer by 7 am
[05:17:09] <Swapper_> anyone that could gime me some hints on how to turn on a spindle fan when rpm is over a cirtain value ?
[05:17:12] <Swapper_> in HAL
[05:25:11] <jthornton> use classicladder
[05:30:06] <Swapper_> jthornton: so no easy way on doin it in hal ?
[05:35:28] <jthornton> wcomp should do it as well
[05:37:34] <Swapper_> ahh that looks like what i need
[05:37:49] <Swapper_> wcomp.N.over bit out
[05:37:54] <Swapper_> ty
[05:38:00] <jthornton> yw
[05:52:42] <Swapper_> it works!
[05:53:10] <Swapper_> a bit buggy precicly at the speed i set since the spindle RPM varies
[05:53:19] <Swapper_> guess i need some sort of filter
[05:53:29] <Swapper_> #spindle fancontrol
[05:53:29] <Swapper_> net spindle-fb-filtered-abs-rpm => wcomp.0.in
[05:53:29] <Swapper_> setp wcomp.0.max 2500
[05:53:30] <Swapper_> net spindlefan wcomp.0.over => hm2_5i25.0.7i77.0.0.output-04
[06:08:51] <jthornton> yea, you need a way to latch it on until some lower rpm is met
[06:09:27] <jthornton> like an off delay timer
[06:23:41] <archivist_herron> there is the lowpass filter to get rid of some noise
[06:33:51] <jthornton> I wish I understood how lowpass worked
[06:35:09] <archivist_herron> a moving average probably
[06:39:59] <jthornton> oh my a k doesn't like the manual cause it doesn't spell it out good enough for him to understand
[06:50:45] <Jymmm> ?
[06:51:38] <Jymmm> AK47?
[06:51:42] <Jymmm> A 'k' ?
[06:51:50] <jthornton> mailing list
[06:52:09] <jthornton> I think it is Aram
[06:52:32] <Jymmm> Ah, doesn't spell out what? lcnc? cnc'ing in general? machining?
[06:53:14] <skunkworks__> he thinks setting up cnc machenes are plug and play. everthing should just magically work.
[06:53:26] <Jymmm> oh, heh
[06:54:58] <SpeedEvil> Well. There do exist CNC machines that come with someone to explain it to you.
[06:55:37] <archivist_herron> that user needs a team to help him
[07:05:03] * jthornton resists responding to that email
[07:05:54] <Tom_itx> skunkworks_, they do but those cost 1/4 mil or more
[07:06:06] <Tom_itx> and come with factory support
[07:06:52] <archivist_herron> and an annual support fee
[07:07:01] <Tom_itx> now seriously... where's the fun in that??
[07:07:34] <archivist_herron> I actually hate ringing support droids
[07:08:13] <archivist_herron> had to do that the last few days setting up some stuff here
[07:44:06] * jthornton goes outside to enjoy the unusually cool day
[07:46:29] <XXCoder> wow its pretty darn cool this morning
[07:46:34] <XXCoder> almost cold lol
[07:51:16] <skunkworks__> polar vorteXX!
[07:51:55] <XXCoder> lol semiporn polar vortex ;)
[08:07:31] <RyanS> why did industry stop using power hacksaws? apparently they were beasts
[08:10:47] <skunkworks__> because band saws worked so much better?
[08:11:21] <RyanS> idk, did they?
[08:12:25] <skunkworks__> no lost time for backstroke
[08:20:17] <jthornton> I couldn't help myself
[08:21:31] <Smidge204__> Might be a bunk comparison, but I prefer my portable bandsaw to my sawzall whenever the bandsaw si capable fo doing the job
[08:22:39] <Smidge204__> So yeah I can see bandsaws being moer popular in production than reciprocating machinery
[08:28:13] <JT-Shop> was I bad?
[08:43:20] <archivist> hehe
[08:48:27] <Loetmichel> re from buying grocerys... that was expensive... 120eur food... and 480 eur new glasses... ( i started to "play the trombone" at reading lately) :-(
[08:49:21] <archivist> what, cheapo Aldi glasses not good enough
[08:50:09] <Loetmichel> archivist: apollo optics. not really more expensive than aldi
[08:50:27] <Loetmichel> but: dual lenses/ smooth transition
[08:50:33] <Loetmichel> thats costly
[09:09:56] <CaptHindsight> eyeglass frames have become quite a racket
[09:13:11] <Loetmichel> the frame was 99 eur
[09:13:35] <Loetmichel> but the varifocal lenses i now need cost a shitload of money...
[09:21:29] <CaptHindsight> http://www.ebay.com/itm/Gerber-Optical-X91002-Coburn-Triumph-Opthalmic-Lens-Finishing-System-Polisher-/251565388400
[09:24:02] <Loetmichel> i am very much on the "DIY" train... but glasses? no, thats aboud 2 orders of magnitude above my capabilitys (precision wise)
[09:24:33] <Loetmichel> besides: calculating the needed lens shape is not really trivial mathematics ,-)
[09:29:18] <CaptHindsight> I started looking into this again after watching that story on the Italian eyeglass cartel, Luxottica
[09:31:40] <CaptHindsight> the eyeglass in an hour places around here just use pre-ground lenses and then just finish the edges
[09:36:47] <CaptHindsight> and lenes may be inkjet printed now, to get the precision so that they don't end up like a Fresnel, is controlling the "slump" of the photopolymer between jetting and curing
[09:38:30] <Loetmichel> CaptHindsight: thats not possible with varifocal
[09:38:48] <Loetmichel> because there are to many combinations of near/farsighted
[09:39:13] <Loetmichel> so any varifocal lenst has to be made on order
[09:40:59] <cradek> and even then, they only barely work
[09:41:14] <CaptHindsight> Loetmichel: yours are the difficult lenses to try to keep all the stock on, but not difficult to print
[09:56:48] <Loetmichel> cradek: right. thats why this glases were so expensive.
[09:57:09] <Loetmichel> the last glases i have here have varifocal also
[09:57:48] <Loetmichel> but wrere cheap, the focus range on the lower half of the lenses is approx. 8mm wide.
[09:58:02] <Loetmichel> used that glasses for about a week
[09:58:08] <Loetmichel> that got fed up with it
[09:58:46] <Loetmichel> now i have ordered one that has about 2/3 of the lens widht as focus range at the bottom... we'll see if that works better
[10:01:18] <skunkworks__> I noticed I am starting to look over my glasses to see things close up...
[10:02:22] <Jymmm> skunkworks__: Do you wear glasses constantly?
[10:05:50] <Loetmichel> skunkworks: like this? ->
http://www.cyrom.org/palbum/main.php?g2_itemId=15029
[10:05:52] <Loetmichel> ;-)
[10:06:56] <skunkworks__> exactly
[10:07:42] <skunkworks__> Jymmm, yes
[10:08:12] <Jymmm> skunkworks__: I see Bi-focals in your future (maybe)
[10:08:31] <skunkworks__> I would probably go reading glasses first
[10:08:38] <Loetmichel> Jymmm: bifocals are outdated
[10:08:51] <Loetmichel> now varifocals are standard
[10:08:52] <Jymmm> Loetmichel: outdated?
[10:09:05] <Loetmichel> i dont know if they are still made
[10:09:13] <Jymmm> Loetmichel: You mean "Progressive Bi-Focals"?
[10:09:44] <Loetmichel> if thets the correct term: yes
[10:09:47] <cradek> of course they are still being made
[10:10:07] <cradek> varifocals have much higher margin so they get pushed on people very hard
[10:10:09] <Loetmichel> i havent seen bifocals with the "inserted lens" a LONG time now
[10:10:34] <cradek> weird. I see standard bi/trifocals all around (midwest US)
[10:10:53] <Jymmm> Ah, they are different things, but same idea.
[10:10:54] <Loetmichel> and the optician i just ordered my new glasses doesnt have them
[10:11:07] <Loetmichel> and cant order them either
[10:11:12] <Loetmichel> i asked her
[10:11:13] <cradek> (I bet that's a lie)
[10:11:21] <Jymmm> yeah, I think so too.
[10:11:26] <Loetmichel> cradek: its a big chain
[10:11:32] <Loetmichel> "apollo optic"
[10:11:40] <Loetmichel> i believe that she cant order them
[10:12:04] <Loetmichel> because she cant order anywhre else than the "mother company"
[10:12:11] <cradek> I've also heard "we only have polycarbonate (aka thin-and-light-but-you-can't-see-shit)" bs
[10:12:21] <cradek> ah then you're just going to the wrong place :-)
[10:12:23] <Einar1> I tried varifocal but it's not for me. Only good thing I can say it's a cheaper way to get disoriented than beer.
[10:12:42] <Loetmichel> Einar1: i have a varifocal i dont use
[10:12:49] <Loetmichel> because it was an even cheaper one.
[10:13:02] <Loetmichel> where the focus range at the bottom half is about 8mm wide
[10:13:13] <Loetmichel> thats way to small
[10:13:39] <Loetmichel> now i get one wiht about 3cm wide focus area
[10:13:53] <Loetmichel> ... which are MUCH more expensive for some strange reason ;)
[10:13:59] <Einar1> I remember a friend of my father had flip down sunglasses over his prescription glasses. Would it not be possible with flip down macro glasses for us old farts?
[10:14:10] <Loetmichel> Einar1: hmmm
[10:14:26] <Loetmichel> why didnt you get me this idea when i was a the optician?
[10:14:50] <Einar1> You did'nt tell me you were going. -)
[10:15:15] <Einar1> Opps forgot his glasses. Here goes :-)
[10:15:23] <Loetmichel> i joked about "someone should invent an autofocus optic mointable on glasses frames..."
[10:15:30] <archivist> I just put two cheap reading glasses or better, use the stereo zoom microscope
[10:15:32] <Loetmichel> ... just got a mild grin ;-)
[10:15:41] * cradek has new glasses with single-vision glass lenses on order
[10:16:15] <Einar1> I actually do connect 2 glasses in serial connection to see really up close.
[10:16:45] <cradek> have not tried glass before... should have better optics than even the CR39 I've used for years. wonder how long 'til I drop them, though.
[10:16:57] <Einar1> And I keep my autodarkening welding helmet to myself. It has correction inserts.
[10:20:19] <Einar1> Loetmichel: Call Google and they can probably reprogram theirs to be autofocus and with crosshairs to find car keys, wrenches and whatnot.
[10:20:57] <Einar1> Say "Car keys" and a crosshairs pop up telling you where they are.
[10:20:58] <Loetmichel> harhar
[10:21:00] <Loetmichel> nice idea
[10:21:23] <Loetmichel> useful use of augumented reality
[10:21:38] <Loetmichel> ... i dont tink that will emerge this decade ;)
[10:22:16] <Einar1> I don't know about you, but to me the decades seems to spin by at an alarming rate!
[10:22:18] <archivist> I seem to remember someone making some varifocal by pumping some liquid between two lenses
[10:22:32] <Loetmichel> i would like to have some contacs tiht integrated displays, though
[10:22:37] <Loetmichel> that would be nice
[10:22:57] <Loetmichel> Einar1: me too
[10:23:14] <Loetmichel> in my memory its like 1990 was "yesterday"
[10:23:49] <Einar1> Some day glasses will be obsolete. We will get nanoservos connected to our eye lens.
[10:24:17] <archivist> you need to replace the lens though as that is the basic fault
[10:24:35] <Loetmichel> archivist; no
[10:24:52] <Einar1> ?? I thought it was our own "servos" getting too weak?
[10:25:05] <cradek> I think the lens becomes inflexible
[10:25:06] <Loetmichel> it would be enough to correctly laser the cornea
[10:25:25] <archivist> inflexible is the problem
[10:25:27] <Einar1> And stiff. Hmm... some unwanted transfer of stiffness here?
[10:25:30] <Loetmichel> and then strenghen themusckles taht do the contracting of the lens
[10:25:55] <cradek> archivist: among the problems... shaped totally wrong in the first place is the second problem some of us have
[10:26:24] <Loetmichel> Einar1: youth shortsightness is usually a "too short" eyeball
[10:26:34] <archivist> I think mine are going a bit out of shape with age too
[10:26:40] <Loetmichel> so that the lens cant go to "infinite focus"
[10:26:57] <Loetmichel> even if the muscles are totally relaxed
[10:27:16] <Einar1> Not mine. I had eagle eyes until late 40ies. Then I found out my arms were topo short. And when I tried glasses my eyes found out "Hey! We don't want to try anymore".
[10:27:18] <Loetmichel> old age short sightess is usually the muscles getting weak/lens getting stiff
[10:27:28] <Loetmichel> ahem
[10:27:35] <Loetmichel> long sightness of course
[10:30:58] <archivist> I remember my old man getting long arms so I made a pair of +1 reading glasses for him
[10:31:09] <Einar1> I use 1 for driving, 2 for work where I use three monitors at more than arms length, 2.5 for reading and 3 for welding and grinding (protective glasses). So my eyes have come in a habit of not doing much adjustment.
[10:31:50] <Einar1> So when a visitor forgot his/hers glasses I can ask "what do you want?" ;-)
[11:07:43] <IchGuckLive> hi all B)
[11:08:06] <IchGuckLive> anarchows ?
[11:11:18] <jdh> any speed/feed/doc suggestions for cutting HDPE with 1 or 2 flute 3mm?
[11:11:19] <Loetmichel> Einar1: all positive?
[11:11:23] <IchGuckLive> ssi: did mesa stuff arrive within 24hr
[11:11:25] <Loetmichel> so you are far sighted?
[11:11:58] <Einar1> Loetmichel: Yes. I'm positive and far sighted. ;-)
[11:12:13] <IchGuckLive> anarchos2: did your joypad work
[11:12:36] <Loetmichel> Einar1:see: i am short sighted AND have the "old age near focos" problem
[11:12:49] <Einar1> Unless I also have a short memory. Harhar.
[11:12:56] <IchGuckLive> why dont you just use the main buttons as pressed not the analog position
[11:13:00] <Loetmichel> results in -1.5 far and +0,75 near correction...
[11:13:15] <Loetmichel> which is quite a span for varifocal lenses
[11:14:47] <jdh> My contacts are -3.5,+1.25
[11:14:59] <Einar1> My collegue always wore glasses, and still does. Until he needs to read the chip marking, when he take off his glasses.
[11:14:59] <Loetmichel> nice one
[11:15:37] <jdh> I rarely wear the contacts since I can't easily take them off to read chip markings.
[11:16:15] <Loetmichel> side effect of wearing glasses all your lifetime since preschool: i never use any protection glasses... which tends to reduce the lifepsan of my correction glasse to less than a year ;-)
[11:16:41] <TekniQue> I'm glad I'm not the only one who has that problem
[11:16:50] <jdh> I have to wear safety glasses out in teh shop so I accumulate lots of them.
[11:16:56] <TekniQue> my glasses get so badly scratched so quickly
[11:17:09] <Einar1> One thing that make varifocals not working for me is I have huge monitors (CAD) so I have to point my nose to the sky to see them. Then my neck hurts badly.
[11:17:10] <Loetmichel> i had angle grinder disc parts ricochet off my glasses more than once ;-)
[11:17:22] <IchGuckLive> UVEX over glass protection is best
[11:17:44] <Loetmichel> NO kind of coating can protect glasses from that
[11:18:10] <Loetmichel> i even had a 300 gram aluminium workpiece fly otu of the vice once...
[11:18:28] <Loetmichel> and brekaking my glasses right in the middle
[11:18:29] <IchGuckLive> fliing parts are bad
[11:18:41] <Einar1> Sometimes I put on glasses, then LEDlenser, then earmuffs. I probably would scare old ladies to run like .....
[11:19:01] <Loetmichel> my optician could belive it "thats acrylic? how did you manage to hreak it in thwo halves?
[11:19:46] <Loetmichel> Einar1: try the "stiff upper lip" attitude ;-)
[11:20:01] <Loetmichel> and i have 2 19" tfts here as well
[11:20:19] <Loetmichel> if i get the money they will be replaced soo by three 22" tfts
[11:20:27] <Loetmichel> have to make room first.
[11:20:33] <Einar1> Some years ago my 5Hp wood chipper sent a big piece of wood in return. It broke my unbreakable safety glasses in the middle like yours and left me with a bleeding nose. And a workng eyesight!
[11:20:56] <Loetmichel> Einar1: nose is alread done...
[11:21:04] <IchGuckLive> anarchos2: ?
[11:21:09] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5519
[11:21:17] <Loetmichel> no bone in there ;-)
[11:21:44] <IchGuckLive> off til later bye
[11:22:42] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12727 <- my workplace at home
[11:23:21] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14073 <- and my office at the company
[11:24:44] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13397 <- and the workbench of course
[11:24:53] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13400 <- side view
[11:25:32] <jdh> way too neat.
[11:25:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13486 <- better?
[11:26:05] <jdh> nope, still too neat.
[11:26:23] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14538 <- more like it?
[11:26:32] <jdh> check one of archivists pics, that's more my look.
[11:26:36] <Einar1> At least it seems like someone did work there!
[11:26:49] <Einar1> (In the last pic.)
[11:26:53] <Loetmichel> oh it does most of the time...
[11:27:01] <Loetmichel> ... much to the dismay of my boss ;-)
[11:27:12] <jdh> so, why not make generic tempest cages that hold 90% of computers?
[11:27:22] <Loetmichel> we do
[11:27:25] <Loetmichel> more or less
[11:27:35] <jdh> oh. they all look customish
[11:27:40] <Loetmichel> depends on the level of shielding required
[11:27:52] <Loetmichel> most OCs can stay in their orignal case
[11:28:06] <jdh> is there any real threat that this solves?
[11:28:07] <Loetmichel> only upgraded by some meters of copper tape and ferrite plates
[11:28:16] <Loetmichel> highes levels: own cases
[11:28:49] <Loetmichel> military beliees so, and as we live from that paranoia we dont say otherwise ;-)
[11:28:53] <Loetmichel> believes
[11:29:24] <jdh> yeah. kind of like inspecting shoes to get on planes
[11:29:32] <Loetmichel> we CAN display the contents of a commercial TFT from 100m away, though
[11:29:40] <jdh> cool
[11:30:02] <Loetmichel> or read any keypress on a ps2 keyboard from the same distance
[11:30:06] <Einar1> If you really throw money at it then you can extract amazing things from what is seemingly white/pink noise!
[11:30:42] <Loetmichel> Einar1: our two measurement chambers are stuffed wiht gear in the 1.5mio eur region
[11:30:47] <Loetmichel> each
[11:31:18] <Loetmichel> you can do some surprising things with this tech ;-)
[11:32:58] <Loetmichel> jdh: or "best level" pc cases are made of 3mm sheet aluminium, any corner line welded. NOT spot welded
[11:33:05] <Einar1> But are they able to extract information or just indicate that it is there?
[11:33:12] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15005
[11:33:19] <Loetmichel> Einar1: the former
[11:34:04] <Loetmichel> but for putting the "bsi" label on it we just have to measure signal levels meet (or be below) a certain envelope
[11:34:35] <Einar1> Will aluminum not take care only of the E emission?
[11:34:35] <Loetmichel> ... and send the measurements to the agency... to get a "approved" measurement number
[11:35:00] <Einar1> I would think you also need mild steel?
[11:35:25] <Loetmichel> Einar1: at 10khz to 4 ghz (what is what we have to measure) aluminium is a short for the M field also
[11:35:50] <Loetmichel> the mild stell is only necessary for lower frequencys
[11:36:03] <Loetmichel> like in the 100s of Hz
[11:36:10] <CaptHindsight> Loetmichel: time to make some Tempest Typewriters
http://arstechnica.com/tech-policy/2014/07/in-the-name-of-security-german-nsa-committee-may-turn-to-typewriters/
[11:36:11] <Loetmichel> steel
[11:36:50] <archivist> quill and ink
[11:36:54] <Einar1> Haha! German NSA commitee = Steampunks?
[11:37:09] <Loetmichel> CaptHindsight: ist easier to soundproof the rooms than to make the typewriters emission free ;-)
[11:37:44] <Einar1> http://www.datamancer.net/keyboards/woodenvso/woodenvso.htm
[11:38:54] <CaptHindsight> Maybe typewriters with encoders. Where have I seen this before?
[11:40:01] <Einar1> Photon processors and fiber comms in the future will make your job obsolete and selling blinds will be back in business.
[11:41:16] <seltecc> hi, my y axis goes in the same direction when I press left and right arrow... how can I change this....
[11:41:48] <jdh> sounds like your DIR pin isn't hooked up
[11:42:00] <jdh> or is improperly defined in the setup
[11:42:24] <seltecc> in the hal or in ini?
[11:42:37] <archivist> may need to scope the connection I have seen bad breakout board design
[11:43:05] <archivist> scope the actual signal see if it is active
[11:43:10] <seltecc> because they were both manualy edit...the ini and the hal
[11:43:31] <jdh> make sure the pin number is correct.
[11:44:33] <seltecc> in what file?
[11:44:34] <CaptHindsight> yes, the breakout boards with no docs, and just a half assed wiring diagram
[11:45:11] <Einar1> Does the Y axis work properly? If so swap X/Y connections to see if the error follows or not.
[11:45:40] <ssi> bleh the guy with the gemini drives hasn't either accepted or declined my offer
[11:45:48] <archivist> I am thinking of the series R
[11:52:45] <Einar1> Loetmichel: Is this you doing some work on your CNC after hours?
http://www.datamancer.com/cart/the-sojourner-display-p-201.html
[11:53:38] <Loetmichel> Einar1: no, but my private CNC has a 12" monitor nearly finished now...
[11:53:57] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14316
[11:54:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14313
[11:54:05] <Loetmichel> :-)
[11:54:12] <Einar1> Those displays look really cool.
[11:54:37] <Einar1> Brass frame?
[11:54:40] <seltecc> yes, I exchanged the connections from x and y from driver to motor and now x has the problem means the pin assignment is wrong?!
[11:54:43] <Loetmichel> yeah
[11:54:55] <Einar1> You welding brass?
[11:55:00] <Loetmichel> soldering
[11:55:19] <Einar1> Ahh. Of course LOETmichel. :-)
[11:55:29] <Loetmichel> of course ;-)
[11:56:01] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14307 <- thats the frame as i milled it
[11:56:56] <Loetmichel> the step is because thete wil be the plugs later, facing downwards so any colling liquiod or stuff will not seep in
[11:57:03] <Loetmichel> there
[11:57:08] <Einar1> Nice piece of origami. And one needs to be sober doing the folds in the right sequence!
[11:57:19] <Loetmichel> right
[11:57:52] <Loetmichel> i do that kind of origami all the time
[11:58:08] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14595
[11:58:37] <Einar1> You must have a good setup with your box & pan brake!
[11:58:48] <Loetmichel> i have none
[11:58:54] <Loetmichel> all done by hand
[11:59:18] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13531
[11:59:19] <archivist> sneaks in bending grooves though :)
[11:59:28] <Loetmichel> right ;-)
[11:59:34] <Loetmichel> lets see
[11:59:59] <archivist> your seeeekwets are not safe with me :)
[12:00:01] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14160 <- ahh, there is some in every state
[12:00:24] <Loetmichel> there you can see the grooves sine
[12:00:27] <Loetmichel> shine
[12:00:52] <Einar1> I have to go stuff something in my face .....
[12:01:19] <Loetmichel> archivist: thats totally ok, these are not secrets ;-)
[12:02:08] <ssi> Loetmichel: nice work
[12:02:20] <Loetmichel> btw: that even works for more complex forms... just have to think a bit harder beforehand, using a 2d "cad" (corel draw)
[12:02:27] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13826
[12:02:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13829
[12:02:33] <archivist> all the modellers and their brass etched stuff use that technique
[12:03:41] <Loetmichel> right
[12:04:25] <Loetmichel> just that i normally use 1.5 to 2mm thick aluminium rather than 0.5mm brass
[12:04:55] <ssi> I wish I had the ability to cut grooves like that with the plasma machine heh
[12:05:02] <ssi> I need to make a sheet metal fume hood for the laser
[12:05:11] <seltecc> is this ok?
[12:05:30] <seltecc> net ystep => parport.0.pin-16-out
[12:05:32] <seltecc> setp parport.0.pin-16-out-reset 1
[12:07:03] <Loetmichel> i am particulary prud of the NAS enclosure.... looks like boght that way when dust coated ->
http://www.cyrom.org/palbum/main.php?g2_itemId=14184&g2_imageViewsIndex=1
[12:07:19] <Loetmichel> proud
[12:07:44] <Loetmichel> (whats "polverbeschichtung" in english?)
[12:07:47] <Loetmichel> pulver
[12:07:53] <ssi> sweet, got the glue gun running again :D
[12:09:53] <jthornton> what are you going to build now?
[12:10:09] <ssi> gonna make some small parts for the laser
[12:10:13] <ssi> feet for the bottoms of the extrusion legs
[12:10:15] <ssi> maybe a tube mount
[12:10:47] <Einar1> Burp!!
[12:10:58] <Einar1> Loetmichel: Powder Coating
[12:11:01] <jthornton> a fellow Spyder person made me a glare shield for my GoPro camera
[12:11:46] <ssi> hehe nice
[12:11:52] <ssi> they can be handy if applied properly
[12:12:02] <Loetmichel> so: ... when its powerder coated in the same tone as the interior
[12:14:55] <seltecc> can I delete this from my hal file?
[12:14:57] <seltecc> setp parport.0.pin-16-out-reset 1
[12:16:28] <JT-Shop> hmm does that turn double stepping on or off?
[12:16:38] <JT-Shop> seltecc, why?
[12:17:44] <archivist> iirc it is just the start(reset) state
[12:18:10] <seltecc> because on 16 is my ystep.. and my y axis goes in the same dir when I press left and right arrow...
[12:18:42] <archivist> your DIR pin is the problem not the step pint
[12:19:28] <seltecc> ok, now I see...
[12:19:58] <seltecc> 16 should be dir and is step.... :(
[12:21:23] <JT-Shop> if an axis goes the same way then no direction information is seen by the drive
[12:21:57] <seltecc> no 16 should be step, sorry. now I know, Thanks... :)
[12:22:01] <archivist> and clocks are getting through on the correct pin
[12:33:54] <IchGuckLive> hi all b)
[12:35:51] <jdh> Hola
[12:35:54] <IchGuckLive> anarchos2: ?
[12:37:14] <ssi> woo, keling order came
[12:37:26] <IchGuckLive> ssi mesa ?
[12:37:40] <ssi> mesa stuff should be here thursday or so
[12:37:57] <ssi> today I got my litle 65ozin nema17s, some leadshine digital drivers, and a 48V switcher
[12:38:20] <ssi> tube isn't going to be here til NEXT thursday :(
[12:38:21] <ssi> so mad
[12:38:39] <jdh> I have to pull this crappy breakout board out of my 6040 and do some soldering to get pins for limits. Not sure it is worthwhile.
[12:39:14] <IchGuckLive> ssi leadshine what 542
[12:39:49] <IchGuckLive> jdh: tb board inside
[12:39:55] <ssi> they're keling branded, and the model number on them is KL5056D
[12:40:17] <IchGuckLive> yes the new modified ones
[12:40:58] <ssi> they look pretty nice
[12:41:03] <jdh> IchGuckLive: the driver boxes look like leadshine/clones
[12:41:32] <IchGuckLive> jdh:
http://www.pro-tos.de/shop/Endstufen/Endstufe-HP-5056-Leadshine-DM556-DIGITAL-5-6A-50V.html
[12:41:38] <IchGuckLive> DM556
[12:42:12] <jdh> not likely for this machine.
[12:43:17] <jdh> ssi: would 0.9degree steppers do anything better for that?
[12:43:43] <ssi> for what?
[12:43:49] <jdh> resolution
[12:43:56] <jdh> for the laser
[12:44:08] <ssi> well sure, they'd double the res
[12:44:35] <ssi> I'm gonna build it as is, with 0.008" per full step, and run 40x microstepping on these drives and see how it does
[12:44:48] <ssi> if I need more res, I'll build reductions
[12:44:52] <jdh> sparkfun has some 400 step 17's
[12:45:10] <jdh> $15 or something
[12:45:10] <ssi> link?
[12:45:36] <IchGuckLive> jdh: i dont think so
[12:45:47] <jdh> https://www.sparkfun.com/products/10846 $17
[12:46:03] <IchGuckLive> for cut no factor on laser engrave picture lines it is worth to go half point size overlap
[12:46:04] <ssi> might be good
[12:48:24] <ssi> dammit
[12:48:28] <ssi> I had a 10% off coupon for sparkfun
[12:48:32] <ssi> that expired 6/30 :(
[12:48:59] <kfoltman> so they were only 990% overpriced? ;)
[12:49:27] <ssi> overpriced compared to what?
[12:49:37] <ssi> if I can get those motors for $1.50 somewhere else, please point me at them :P
[12:49:45] <kfoltman> which motors?
[12:49:55] <kfoltman> $15 for nema17 sounds fair
[12:49:59] <ssi> 68oz 400step motors
[13:11:37] <IchGuckLive> AT all cand i set up a Gecko G540 to halfstepping
[13:11:46] <jdh> 10x only
[13:11:49] <IchGuckLive> arend there DIP switches
[13:13:13] <IchGuckLive> jdh: is this fix
[13:13:17] <ssi> ok printing part one of my tube mount :D
[13:13:21] <IchGuckLive> no change at all
[13:13:36] <jdh> Ich: I'm fairly sure they are fixed 10x only
[13:13:58] <IchGuckLive> so at 20Turns per inch i got 32000 steps
[13:23:50] <IchGuckLive> oh east cost USA bad weather in view sevier Thunderstorm local flooding
[13:43:18] <pcw_home> If you want 1/2 stepping (and 3 axis is enough) a MX3660 is probably a better choice than a G540
[13:43:38] <IchGuckLive> i see
[13:43:56] <pcw_home> Icy
[13:46:03] <pcw_home> also 6A vs 3.5 and 60V vs 50
[13:51:08] <IchGuckLive> PCW agree i Love Europ no Gecko
[13:51:26] <IchGuckLive> never got that problem in all my 200+ mashines
[13:52:23] <IchGuckLive> pcw_home: sorry icy that your distributor now also got geckos
[13:53:01] <IchGuckLive> http://www.retrofit-plus.at/
[14:01:06] <pcw_home> Geckos are fine but if you are software stepping their 1/10 ustep ratio may be a bit high
[14:02:55] <pcw_home> ( MX3660 is Leadshine )
[14:04:10] <IchGuckLive> i use leadshine most :-)
[14:04:28] <IchGuckLive> not loving it as to many clones on the maket fail on speed
[14:04:56] <pcw_home> MX3660 is 3 Axis + breakout and can be programmed for 1/2 to 1/64 ustep ratios
[14:11:11] <anarchos2> new controllers just arrived :D
[14:12:11] <anarchos2> stupid DHL charged me ~$15 in fees, though. $2 tax from government, $10 to DHL for a "processing fee" and $4.25 to DHL for a COD fee
[14:15:55] <JT-Shop> lol
[14:22:02] <anarchos2> they charge me $4.25 to give them $10 -_-
[14:25:55] <jdh> nice trick. I'll only charge you $3 if you give me $10
[14:28:18] <Jymmm> I need change... Do you have two twenties for a ten?
[14:28:58] <Jymmm> (Yes, that DOES work too)
[14:31:06] <IchGuckLive> BYE
[14:40:21] <K6MLE> Is there someone familiar with the proper setup of a Gecko G540 that might be able to give me a bit of help with proper configuration?
[14:40:44] <jdh> K6MLE: ask the real question and see.
[14:41:24] <K6MLE> I have a problem with stalling when the X & Y axes attempt to make an arc ...
[14:41:49] <jdh> power supply big enough?
[14:42:26] <K6MLE> The supply is an 8A supply set for 45 volts ... regulated.
[14:43:12] <jdh> it only occurs on arcs?
[14:43:15] <K6MLE> Motors are 200 step/rev 3.2V 2.8A 3.6mH NEMA 23's.
[14:43:33] <K6MLE> It only appears to occur on arcs ... not a travers .
[14:44:41] <jdh> that sounds like lack of power for both motors. Do you have the appropriate current resistors for the motors?
[14:45:19] <cradek> it might be a mechanical resonance problem -- near reversals on arcs, the motors move very slowly
[14:45:20] <K6MLE> The resistors are all 2.7K ...
[14:45:38] <cradek> for your traverse you might be accelerating through this troublesome resonant frequency very quickly
[14:45:46] <K6MLE> I should mention that the motors aren't mounted .. just sitting on a bench top.
[14:45:56] <cradek> aha yeah, it's resonance
[14:46:13] <cradek> clamp them down and put some weight on the shafts and it'll go away
[14:46:47] <K6MLE> That simple!?
[14:46:47] <skunkworks> 2nd'ed...
[14:46:50] <cradek> I bet so
[14:47:23] <K6MLE> Should I be able to go with the default G540 configuration in stepconf?
[14:47:45] <cradek> you'll have to customize at least scale, velocity, acceleration
[14:48:28] <K6MLE> That seems a bit scary to this newbie! :)
[14:48:54] <K6MLE> I'm pretty good with electronics .. not much of a machinist!
[14:53:52] <ssi> scale is how you map steps to linear travel; depends on the machine
[14:54:14] <ssi> velocity and accel you just sorta set based on what you want and tweak it til everything runs smoothly
[14:55:07] <ssi> but there's no one size fits all number because the velocity and accel your machine can do depend on the steps per travel, torque of the motors, weight of the joints, etc
[14:56:19] <K6MLE> ssi: That makes sense ... I wonder if I should start a new config file using the defaults for G540 in stepconf?
[14:56:39] <ssi> yes
[14:57:37] <K6MLE> ssi: Okay ... and then I suppose I adjust the INI file from there?
[14:57:43] <ssi> yep
[14:57:58] <K6MLE> And that's done manually (gedit), right?
[14:58:05] <ssi> yeah
[14:58:25] <K6MLE> Okay ... back to the drawing board! :)
[14:58:38] <ssi> haha
[15:06:52] <ssi> https://pbs.twimg.com/media/BsnBIL1IYAMfLvT.jpg
[15:09:34] <skunkworks> ssi, whatcha making?
[15:11:10] <ssi> laser tube mount
[15:11:23] <skunkworks> ah - neat
[15:12:28] <anarchos2> http://imgur.com/CLKSQdi
[15:12:59] <anarchos2> just need UPS to deliver my PSU that's been sitting in Anchorage (??!) for 4 days now
[15:14:37] * JT-Shop hasn't been home to Alaska for a long time now
[15:15:58] <anarchos2> i'm assuming it's going to go somewhere else before it gets to me too :(
[15:16:16] <anarchos2> i doubt UPS send a plane from Anchorage to Vancouver ever
[15:16:29] <anarchos2> will probably fly down to Seattle or LA before coming back up
[15:45:20] <anarchos2> slightly confused about the wiring between my controller and PSU
[15:45:35] <anarchos2> controller has +Vdc and GND
[15:47:16] <anarchos2> i connect +Vdc to the +V on the PSU, but then do i connect -V to GRD, or do i connect GND to the ground on the PSU?
[15:47:48] <anarchos2> if i do the latter it's not gonna work because of a lack of a -V connection anywhere...
[15:47:53] <ssi> V-
[15:47:59] <ssi> the ground connection on the psu is probably the mains ground
[15:48:33] <anarchos2> yea makes sense, just wanted to make sure :)
[15:49:50] <anarchos2> so next question is about my wiring colour scheme...i take it that this would be a "Two-Wire Grounded DC Power - Negative Ground" system?
[15:50:09] <ssi> yeah
[15:50:14] <anarchos2> and i should make +V red, and -V white
[15:50:24] <ssi> red and black would be my instinct, but red and white works too
[15:51:12] <anarchos2> ok
[16:06:25] <ssi> so I realized last night
[16:06:34] <ssi> I built the laser table into a room with a door smaller than the smallest dimension on the table :(
[16:07:26] <sirdancealot> use the laser
[16:10:55] <Deejay> gn8
[16:12:21] <ssi> lul
[16:36:49] <cradek> http://www.craigslist.org/about/best/hvn/4493372708.html
[16:38:17] <ssi> ha
[16:38:39] <jdh> somewhere, there is probably someone who desperately wants that vehicle.
[16:38:44] <ssi> yeah, me
[16:38:45] <ssi> :D
[16:42:52] <ink_> lol
[16:42:56] <ink_> nice exhaust
[17:01:18] <ssi> why am I sitting here accurately modeling crap in solidworks that doesn't need to be accurately modeled :P
[17:05:15] <ink_> to better your understanding of it?
[17:06:54] <ssi> no... not in this case
[17:06:58] <ssi> I'm just making it look overly pretty
[17:07:42] <ssi> https://pbs.twimg.com/media/Bsncx93IEAMFcOB.png:large
[17:14:13] <zeeshan|2> !
[17:14:21] <zeeshan|2> i made that shit
[17:14:22] <zeeshan|2> :D
[17:14:27] <zeeshan|2> in solidworks
[17:14:27] <ssi> eh?
[17:14:29] <zeeshan|2> kl8070d
[17:14:34] <ssi> this one's a kl5056D
[17:14:37] <zeeshan|2> oh
[17:14:55] <zeeshan|2> mine wasn't accurate at the pins though :p
[17:14:58] <ssi> i wonder if they're the same size
[17:17:26] <zeeshan|2> they look similar
[17:17:26] <zeeshan|2> ;p
[17:18:01] <ssi> yea
[17:18:46] <ssi> man my 3d printer is running great
[17:18:52] <ssi> I expected to have to screw with calibration and setup
[17:18:57] <ssi> but nope, it dusted right off and went to work
[17:21:14] <zeeshan|2> nice
[17:22:22] <zeeshan|2> http://i.imgur.com/YeKAwQk.png
[17:22:29] <zeeshan|2> look similar
[17:22:34] <zeeshan|2> in sisze
[17:23:05] <ssi> yeah
[17:23:09] <ssi> thant's exactly why I modeled mine, too
[17:23:12] <ssi> I'm about to model the psu
[17:48:26] <kfoltman> ssi: what extruder are you using?
[17:48:51] <ssi> this machine's got a regular wades style extruder with herringbone gears and a j-head
[17:49:02] <ssi> the other machine has the same extruder witha budaschnozzle
[17:49:12] <ssi> they both work well
[17:50:39] <kfoltman> where did you get the wades and the j-head?
[17:50:50] <kfoltman> I'm slightly afraid of buying from a non-recommended source
[17:50:59] <ssi> printed most of the parts actually
[17:51:08] <kfoltman> and the hot-end?
[17:51:10] <ssi> I started with a kit, and I've been through half a dozen machines at this point
[17:51:14] <ssi> ummm.. lemme see
[17:51:28] <ssi> hotends.com
[17:51:47] <Tom_itx> did that prusa hotend ever take off?
[17:51:57] <ssi> ?
[17:52:09] <Tom_itx> the SS one he was working on forever
[17:52:16] <ssi> I never saw it
[17:55:21] <ssi> https://pbs.twimg.com/media/BsnnrCuIUAAsrBQ.jpg:large
[17:55:23] <ssi> mk1 tube mount
[17:55:26] <ssi> it's not perfect, but it's close
[17:55:46] <ssi> need to increase the radius in the outside frame substantially for rigidity, and maybe thicken up the wall as well
[18:09:09] <zeeshan|2> 3d print me something
[18:09:10] <zeeshan|2> :P
[18:09:56] <Tom_itx> most of em just print more printers
[18:10:35] <zeeshan|2> i want a 3d printed
[18:10:40] <zeeshan|2> cover for an electric motor
[18:10:44] <zeeshan|2> =/
[18:10:57] <Tom_itx> i think Connor made some of those
[18:11:42] <ssi> I made some too
[18:11:58] <ssi> and I made plastic mounts that screw to the back of the stepper and provide mounting holes for encoders
[18:12:00] <zeeshan|2> not for a stepper
[18:12:05] <zeeshan|2> i need it for an induction motor
[18:12:10] <zeeshan|2> print me some ssi!
[18:12:14] <ssi> how big
[18:12:15] <zeeshan|2> $5!!
[18:12:17] <zeeshan|2> jk
[18:12:24] <zeeshan|2> i'd have to measure it
[18:12:30] <ssi> I can only do 200x200x100mm
[18:12:31] <zeeshan|2> but its 4" wide by 2.5" long
[18:12:36] <zeeshan|2> and like 2" deep
[18:12:40] <ssi> that's doable
[18:12:49] <zeeshan|2> does it cost a lot to print
[18:13:04] <zeeshan|2> cause if it does
[18:13:10] <zeeshan|2> i might just machine it out of plastic
[18:13:10] <zeeshan|2> ;p
[18:13:19] <zeeshan|2> i just want to own a 3d printed part
[18:13:30] <jdh> I got a customs bill from DHL for my 6040. $24
[18:13:31] <zeeshan|2> all the cool guys/girls have something 3d printed ;[
[18:13:54] <ssi> it's not terribly expensive
[18:14:07] <ssi> it's more expensive than it ought to be though... ABS filament is overpriced
[18:14:20] <zeeshan|2> cant you just feed zip ties into the extruder
[18:14:21] <zeeshan|2> :p
[18:15:24] <ssi> sure, as long as they're perfectly round 3mm zipties
[18:15:31] <SpeedEvil> ssi: there are several filament extruders around
[18:15:36] <ssi> yeah i know, I have one
[18:15:41] <ssi> I just haven't put it togehter yet :P
[18:16:10] <zeeshan|2> im sure you can crunch up the zip tie
[18:16:12] <zeeshan|2> into small bits
[18:16:16] <zeeshan|2> and feed it through a hopper or something
[18:16:22] <ssi> if you have a filament extruder
[18:16:25] <zeeshan|2> o
[19:36:59] <humble_sea_bass> http://irclo.gr/i/152311/6Rmt877.gif
[19:37:13] <humble_sea_bass> this is what i do before going into my shop
[19:38:50] <XXCoder> heys
[19:39:02] <humble_sea_bass> yo
[19:39:16] <XXCoder> and lol on link
[19:42:29] <XXCoder> my cnc couplers finally arrived
[19:42:33] <XXCoder> woot.
[19:42:41] <XXCoder> and found new problem lol
[19:43:10] <XXCoder> when I use motor mount, motor rod and ball screw does not line up
[19:43:19] <XXCoder> off by I guess 1/4 in
[19:43:24] <XXCoder> "yay"
[19:44:15] <AR_> you need a super flexible coupler
[19:44:32] <XXCoder> sure I'll just use toy spring
[19:51:12] <SpeedEvil> Duct tape.
[19:52:32] <XXCoder> 1/4 in thick not bad lol
[19:56:58] <ssi> XXCoder: oldham coupler!
[19:57:48] <XXCoder> its offset by height not distance to each other lol
[19:57:55] <XXCoder> simple solution though
[19:58:05] <XXCoder> just move ball screw and rails up
[20:00:21] <ssi> look it up before you dismiss me
[20:00:21] <RyanS> I am putting quick and dirty and coolant system on my 4 x 6 bandsaw, you think 3 L a minute is sufficient?
[20:00:44] <XXCoder> 1ML/ms
[20:01:26] <RyanS> umm
[20:02:08] <RyanS> 50ml/s ......
[20:02:42] <XXCoder> 60000000000 liters a minute
[20:02:46] <jdh> I have oldhams on my mill
[20:02:54] <SpeedEvil> RyanS: 1mL/s of water heated by 50C will cool by 200W
[20:03:00] <XXCoder> thats what my suggestion was LOL. I bet it'd be so fast it'd cut stock by itself.
[20:03:46] <SpeedEvil> RyanS: 50ml/s is quite adequate for anything sensible if you can get all of the coolant to the cutter
[20:04:02] <ssi> ok I'm about to cut a big part with a lot of pierces, I only have one piece of metal big enough
[20:04:04] <SpeedEvil> more may be an idea if you can only get a tiny fration
[20:04:13] <ssi> lets hope my thc crap doesn't ruin this one shot
[20:04:31] <SpeedEvil> Good luck
[20:04:33] <XXCoder> good luck and do a air cut first
[20:04:47] <SpeedEvil> Or a polystyrene cut
[20:05:00] <XXCoder> thats better but if can afford or buy
[20:05:09] <ssi> air cut doesn't help
[20:05:16] <ssi> it only is a problem when the thc is running
[20:05:46] * SpeedEvil just took delivery of 12m^3 of foam.
[20:06:10] <RyanS> Why do some bandsaws have coolant nozzles over both blade guides? Is it simply for larger machines?
[20:06:51] <SpeedEvil> RyanS: helping chip flow?
[20:08:16] <RyanS> I guess it couldn't hurt to have two
[20:08:39] <XXCoder> more is better
[20:09:01] <XXCoder> well till the system starts to outweigh the machine lol
[20:10:49] <RyanS> how about an agricultural pump..... say 50l a second :)
[20:11:20] <RyanS> It would be flood in every sense of the word
[20:11:43] <XXCoder> borrow a fire truck
[20:16:18] <jdh> g10 l2 p1 r180 will 'mirror' x?
[20:16:29] <ssi> I guess that was too much to ask for :(
[20:16:41] <ssi> being able to use 'run from here' is too much to ask for also
[20:17:08] <RyanS> That's a good point vertical bandsaws don't use the coolant, and presumably they use bimetal
[20:52:20] <ssi> blah
[20:52:23] <ssi> that was a complete failure
[21:11:44] <ipz> https://www.youtube.com/watch?v=eUdBWDo_Xe8 (CNC Design to Cut in 5m)
[21:53:21] <ssi> mmm, warm printy bits
[21:53:24] <ssi> just like mom used to make
[23:06:39] <ssi> quiet in here tonight!
[23:08:12] <XXCoder> yeah
[23:16:08] <ssi> makes me sad
[23:22:33] <XXCoder> oh well
[23:22:51] <XXCoder> this channel is MUCH more noise than more general #CNC channel
[23:39:59] <CaptHindsight> that channel smelled like socks, open a window
[23:40:13] <XXCoder> lol
[23:49:56] <ssi> :)
