[00:31:29] <Jymmm> How do you flip something over? I see it down on a variety of items in a production line, But I can't find anything to read up on it. Mostly flat things like a tortilla, plate, casino chips, lids, etc, mostly round discs.
[00:31:40] <Jymmm> s/down/done/
[00:32:10] <Valen> locating pins as a rule
[00:32:25] <Jymmm> in the disc?
[02:04:30] <Deejay> moin
[02:05:30] <SpeedEvil> http://new.livestream.com/spacex/DragonV2 - contains 3d printed rocket engine.
[02:05:37] <SpeedEvil> Now that's proper 3d printing.
[02:05:41] <SpeedEvil> Morning.
[03:36:54] <miss0r> yestarday morning I was offered a Roland CAMM-3 PNC-3100 for ~1200 USD. Is it worth the money? (only run for 4 hours total, and have been in heated dry storage ever since)
[03:43:30] <Einar1> I would have seen it move in all axes and run the spindle. If it did, I'd stuff $1200 in his pocket, pick up the machine and drive away before he could change his mind.
[03:44:01] <Einar1> Does that make it worth $1200? For me, yes. I don't know your plan and intended use.
[03:58:56] <SpeedEvil> It is really hard to kill a Decent machine in 4 hours.
[03:59:22] <SpeedEvil> But can be done by a skilled operator.
[09:26:52] <Jymmm> 4TB ext $159 http://www.frys.com/product/7410405?site=sa:adpages%20page:P35_FRI%20date:053014
[09:49:56] <Jymmm> JT-Shop__: You know, you could make dashboards for CanAm and make a killing! Just no style to them, maybe even have a place to have built in phone/gps docks, stereo, clock, radar, or even replace the speedo with aftermarket
[09:51:04] <Jymmm> JT-Shop__: even a place for cams too fwd and rear facing (theft/cops, etc)
[10:18:31] <Jymmm> If you play with a lot of various ISO's http://isostick.com/
[10:19:19] <Jymmm> No mor eburning cd's or mucking around with usbstick bootloaders
[10:23:59] <Jymmm> Well, sorta... http://wiki.isostick.com/index.php?title=Tested_Hardware
[11:57:10] <IchGuckLive> hi all B)
[12:20:26] <zq> that nml interface
[12:20:31] <zq> asdfgrmladsflkj
[12:21:00] <zq> it's almost as if the cpp parts were written in c-with-classes
[12:30:04] <IchGuckLive> zq: most is written in c
[12:32:11] <zq> '*.cc' -exec wc -l {} + | tail -n 1
[12:32:11] <zq> 98396 total
[12:32:11] <zq> *13:14:06 ~/dev/machinekit/src> find . -iname '*.c' -exec wc -l {} + | tail -n 1
[12:32:14] <zq> 153044 total
[12:32:24] <zq> *13:13:43 ~/dev/machinekit/src> find . -iname '*.cc' -exec wc -l {} + | tail -n 1 98396 total
[12:32:58] <IchGuckLive> what are you trying to relise
[12:32:59] <zq> the inherent verbosity of c tilts the balance away from it further
[12:33:14] <zq> right now? that most of it is c-with-classes, sort of
[12:33:28] <zq> before that i was gonna suggest rewriting the nml layer
[12:33:51] <zq> already wrote a(n idiomatic) cpp wrapper around hal, not sure if it would be of interest
[12:34:06] <IchGuckLive> what benefit do you think this is gone get the community
[12:34:30] <zq> dunno, how would code quality benefit the community?
[12:35:06] <IchGuckLive> alot i thin but it is almost rewritten now as the new kernels are going to take place
[12:38:12] <IchGuckLive> zq querry
[12:43:30] <CaptHindsight> looks like a fest in Houston the weekend of October 17th
[12:43:50] <zq> j #emc-devel
[12:44:02] <IchGuckLive> #linuxcnc-devel
[12:44:14] <zq> old habits die hard
[12:44:24] <IchGuckLive> O-o
[12:44:29] <IchGuckLive> O.o
[13:13:23] <IchGuckLive> im off early BYE BBQ here as always
[14:51:38] <Connor> Dang it.. the shaft of my digital probe is dead-nutz on at 3/8" and won't fit into my Low Profile 3/8" TTS Tool holder..
[14:52:07] <Connor> End mills fit into the tool holder just fine.. but.. they mic out to be around .3745" The shaft mics out to .375"
[14:53:43] <jdh> put it in the freezer
[14:53:50] <Connor> Yea.. doing that now..
[14:54:08] <Connor> I just don't want to lock it in forever.. Probably could drive it out if need be.
[14:54:40] <Connor> I had no idea endmills were undersized..
[14:55:26] <jdh> seems like something that will live there forever?
[14:55:47] <Connor> Most likely.. but, you never know. :)
[14:56:10] <jdh> but another low-profile 3/8" holder
[14:56:14] <Connor> as long as I can unscrew & screw the shaft from the probe...
[14:56:19] <Connor> I should be good.
[14:56:38] <Connor> probe can act as a tool setter too.. and will use it till I finish build mine.
[14:56:47] <jdh> which probe?
[14:57:13] <Connor> Once like CNC4PC sells, only from the guy who makes it.. and not the reseller.
[14:57:28] <Connor> http://www.wildhorse-innovations.com/index.php?_a=viewCat&catId=9
[14:58:08] <archivist> were you expecting +- 0 exactly
[14:58:36] <Connor> archivist: No. I was excepting the shaft to fit into a 3/8" holder just like endmills..
[15:00:15] <archivist> I person at a previous job used to put +- 0 on his drawings, I asked what he expected, his reply was, they should do the best they could
[15:05:51] <Connor> wonder how long I need to keep it in the freezer...
[15:06:06] <cradek> longer than that
[15:06:27] <jdh> I have some liquid He at work. much faster
[15:06:49] <cradek> you can get a LOT more temperature differential with the oven than with the freezer
[15:06:52] <Connor> longer than what? 10 minutes ?
[15:09:18] <Connor> I guess I could chuck it up in a collet and take some steel wool or emery clothe to it..
[15:09:43] <Connor> flip to around and to the other end a tad more than the main shaft..
[15:10:25] <jdh> put the tool holder in the oven
[15:10:25] <Connor> It's dark colored.. Looks like maybe it was Drill rod and not CRS
[15:14:26] <CaptHindsight> https://www.kickstarter.com/projects/tomwang/voltset-worlds-smartest-multimeter-for-smart-devic
[15:15:30] <CaptHindsight> and I was just about to launch my 4 channel digital scope and 10GHz spectrum analyzer dongle
[15:17:36] <archivist> that is a dumb toy
[15:18:50] <archivist> Connor, if black I bet it is above size
[15:19:24] <archivist> 1200 grit wet and dry paper to polish it down
[15:26:25] <archivist> CaptHindsight, I like the claim of a high resolution yet the accuracy is much worse than the fluke
[15:29:52] <CaptHindsight> looks like anything electronic or electromechanical that can be controlled by a smartphone is popular, no matter how impractical or lousy the implementation
[15:30:50] <PCW> there's a sucker with a smartphone born every second...
[15:32:16] <PCW> I'm sure _some_ of the ideas are useful
[15:34:31] <archivist> the practical joke will be ringing them up just as they probe a few KV
[15:38:47] <CaptHindsight> https://www.kickstarter.com/projects/13588168/papilio-duo-drag-and-drop-fpga-circuit-lab-for-mak?ref=category Spartan 6 duino board
[15:42:01] <PCW> except that schematics are a giant leap backwards
[15:50:08] <archivist> google is failing me cannot find any info on http://www.collection.archivist.info/searchv13.php?searchstr=mac+press
[15:52:28] <Jymmm> https://www.google.com/search?q=mac+press+site%3Ahttp%3A%2F%2Fwww.colection.archivist.info%2F#q=%22mac+press%22+site:http:%2F%2Fwww.collection.archivist.info%2F
[15:55:04] <archivist> Jymmm, you need to learn to spell and how to use google site search
[16:04:19] <Jymmm> archivist: ?
[16:05:39] <archivist> you spelled collection with one l
[16:06:10] <archivist> and I am trying to find info on other sites not my own
[16:06:11] <Jymmm> wrong link pasted... https://www.google.com/search?q=mac+press+site%3Ahttp%3A%2F%2Fwww.colection.archivist.info%2F#q=%22mac+press%22+site:http:%2F%2Fwww.collection.archivist.info%2F
[16:16:04] <tjtr33> PCW leap backwards? is it that you recommend the xilink ide? maybe better control, theres more than connections
[16:17:24] <Deejay> gn8
[16:17:26] <PCW> Schematic capture has been pretty much abandoned as a serious design entry system for hardware
[16:19:11] <SpeedEvil> yeah - today everyone uses breadboards full of TTL chips, and OCR.
[16:19:17] <tjtr33> :) tjtr33 runs ICT PLACE under DosBox
[16:19:45] <archivist> ICT PLACE that is a name from the past
[16:20:05] <tjtr33> peels is not fer pizza
[16:21:29] <PCW> scehmatics are perhaps useful for visualization but IMHO not useful for hardware entry above PCB layout anymore
[16:22:50] <archivist> I realise the kiddies of today think in pictures but....they are misguided
[16:23:36] <PCW> I guess there's a place for the "Labview" type environment but not having the power of a language is very limiting
[16:25:59] <tjtr33> i think in pictures too, sorta basic human thing. pix 'just work' while text is a finesse _after_ the frame is understood
[16:27:59] <PCW> I sketch stuff out on paper, and then type it in
[16:28:53] <tjtr33> agreed
[16:29:43] <PCW> One issue with schematic capture is portability (or lack of same)
[16:30:59] <tjtr33> ORCAD also runs on DosBox ;)
[16:31:14] <PCW> once you learn this particular whizbang tool, what do you actually know?
[16:32:29] <CaptHindsight> can we get rid of ladder logic while we're at it :)
[16:32:50] <tjtr33> the papilio thing? well kids get started. they can learn vhdl later https://github.com/hamsternz/IntroToSpartanFPGABook/blob/master/IntroToSpartanFPGABook.pdf
[16:32:59] <PCW> you would have to get rid of electricians
[16:35:52] <tjtr33> CaptHindsight, are you using Automation Direct Koyo's? DirectSoft is a text language. mine came with it free, build your own cables tho
[16:36:32] <tjtr33> (no ladder)
[16:36:35] <CaptHindsight> tjtr33: picked up a few from flebay
[16:36:57] <CaptHindsight> was using DirectSoft5
[16:37:10] <CaptHindsight> hate it
[16:38:08] <CaptHindsight> http://www.automationdirect.com/adc/Shopping/Catalog/Software_Products/Programmable_Controller_Software/DirectLOGIC_PLC_Programming_Software_%28DirectSOFT%29/PC-DSOFT5
[16:39:23] <tjtr33> 400$, masochistic!
[16:39:38] <CaptHindsight> yeah, I didn't pay that
[16:40:59] <tjtr33> wow they charge 250 for the langiuage based one. hope you got one else i can dig mine up for ya
[16:42:01] <tjtr33> used 'em in a shuttle-carousel tool changer ( carousel slide in and out of work area ... was garbage--- wiggly!)
[16:42:55] <tjtr33> bye
[17:06:46] <Connor> how hot do I need to get this tool holder do you think?
[17:06:56] <Connor> I just put it in the oven at 350F
[17:12:17] <SpeedEvil> Calculate.
[17:12:28] <SpeedEvil> What is the coefficient of linear expansion of steel?
[17:12:36] <Connor> Beats me..
[17:12:36] <SpeedEvil> What is the factor you need it to expand.
[17:12:38] <SpeedEvil> Divide.
[17:12:41] <SpeedEvil> Google
[17:21:25] <CaptHindsight> SpeedEvil: http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html
[17:22:11] <CaptHindsight> varies over a wide range depending on alloy
[17:25:10] <CaptHindsight> don't you need to shrink the tool? Heating the tool holder will make it expand making the ID smaller
[17:31:31] <CaptHindsight> depending on the shape
[17:32:38] <Connor> No, heading expanded it... just not enough.. it shrunk after I got about 1.5mm of the thing into it..
[17:32:47] <Connor> going to go get some 1200 grit sandpaper.
[17:32:54] <Connor> will polish it..
[18:50:35] <Connor> Well, couldn't find 1200 at home depot, best I could find was 600.. but, it worked.. got it in the toolholder..
[19:41:37] <Connor> Hey, question, is it possible to share input for limits / home switches with probe input?
[19:41:45] <Connor> Or is that a bad idea?
[19:42:01] <jdh> if the probe input goes off during a non-probe move it errors
[19:42:09] <cradek> you could probably do it with some hal gimmickry, but it's a bad idea
[19:42:26] <cradek> homing is a great way to bust your probe
[19:42:34] <jdh> heh
[19:42:43] <cradek> limits? I don't see how you could combine those.
[19:42:52] <cradek> home maybe.
[19:43:06] <Connor> jdh: I would use a jack that connects the tip or whatever when you unplug the plug.
[19:43:15] <cradek> jogging is the other great way to bust your probe!
[19:43:19] <Connor> cradek: My limits / home are the same.
[19:43:21] <cradek> well there are lots of ways
[19:43:35] <jdh> get a 5i25
[19:43:43] <jdh> you know you want one anyway
[19:43:47] <Connor> jdh: I will at some point.
[19:43:54] <cradek> well you don't want to disable your limit switches while probing. that's just stupid.
[19:44:19] <jdh> pci p-port card?
[19:44:33] <Connor> No.. The jack would be for the probe.. to keep the circuit in tact when probe not installed.
[19:44:39] <cradek> is the probe homemade and wired?
[19:44:46] <Connor> I'm using 3 inputs for the spindle encoder, and 1 for the limits.
[19:45:01] <Connor> cradek: I bought it.. $125.00 passive probe.
[19:45:06] <cradek> maybe you could use serport
[19:45:35] <Connor> I have 3 parports.. but, only one breakout.
[19:45:36] <cradek> well your spindle won't be running while you're probing. maybe use one of those?
[19:45:59] <Connor> Aren't their 5 inputs on parport ?
[19:46:03] <Connor> or just 4 ?
[19:46:38] <Connor> 10,11,12,13 and 15
[19:47:21] <Connor> CRAP. I'm using the other for the charge pump
[19:48:51] <Connor> I guess I'll play with it using the input for the limits seeing as I don't have all of them hooked up yet.. infact.. non of them are right now.. redoing them..
[20:26:41] <XXCoder> hey all
[22:08:22] <Connor_mill> hey guys, question. does motion.probe-input auto debounce? or do I need to add one ?\
[22:08:35] <Connor_mill> if so, what's a good delay time ?
[22:08:46] <jdh> no debounce on mine
[22:11:16] <skunkworks_> no debounce here either - but I am using an opto22 which seems to be very good at debounce
[22:12:09] <jdh> I'm using a wire run straight to teh pport pin
[22:13:43] <Jymmm> bouncy house?
[22:18:14] <Connor_mill> looks like I'm getting around .0001" on the Z with it..
[22:18:20] <Connor_mill> repeatability that is.
[22:19:15] <Connor_mill> the faster I go, the worse it gets.. Guess that's to be expected ?
[22:19:43] <jdh> double probe
[22:49:15] <Connor> I got my probe working.. now to just calibrate the tip..
[22:53:25] <Jymmm> cool
[22:55:54] <ChuangTzu> gazprom
[22:55:55] <ChuangTzu> lol
[23:14:36] <Jymmm> Is there anything any has used to kill ants indoors that's safe around pets and actually works (being you've actually used it more than once and it kills the lil bastards)?
[23:14:49] <FrankZappa> boric acid, no?
[23:14:53] <Jymmm> not pets safe
[23:14:57] <FrankZappa> k
[23:15:00] <FrankZappa> continuous glue strips
[23:15:00] <FrankZappa> ;)
[23:15:04] <Jymmm> lol
