[02:08:35] <Sairon> howdy
[02:08:47] <Sairon> researching takt time, production leveling, etc
[02:10:09] <jdhNC> how lean of you.
[02:13:46] <Sairon> truly
[02:13:56] <Sairon> eh, so, the company i work for is a startup
[02:14:14] -!- i_tarzan [i_tarzan!~i_tarzan@] has joined #emc
[02:14:14] <Sairon> and the manger types are all gung ho about lean
[02:14:33] <Sairon> however, i never actually see them on the manufacturing floor implementing such a thing
[02:14:40] <Sairon> it seems like... they don't know how to
[02:14:41] <jdhNC> you should hire a lot of lean-six-sigma masterbating black-belts
[02:14:54] <Sairon> so they just pretend it's happening, or something
[02:14:59] <Sairon> at the end of the day, the result is
[02:15:06] <Sairon> nothing is really tracked
[02:15:13] <Sairon> there's no... organization
[02:15:17] <jdhNC> how many $millions do they claim they have saved?
[02:15:28] <Sairon> they don;t yet
[02:15:33] <Sairon> so here's my thing
[02:15:38] <jdhNC> oh, they must not be very good
[02:15:45] <Sairon> is to give some recommendations to the guys on the floor
[02:15:46] <jdhNC> do they make nifty presentations?
[02:15:58] <Sairon> for some sort of realistic means of tracking and controlling production
[02:16:19] <Sairon> if it can tilt towards being a "lean" thing
[02:16:28] <Sairon> then it needs less selling at the management level
[02:16:30] <jdhNC> they need a robust 6-sigma DMAIC process for that
[02:16:36] <Sairon> hah
[02:17:23] <jdhNC> with all the money our lean-six-sigma-master-black-belts have saved us, I'm sure we are effectively printing money.
[02:17:44] <Sairon> i'm certain
[02:17:50] <Sairon> at the end of the day...
[02:18:08] <Sairon> i'm pretty much the only person there who has actually worked in any form of manufacturing
[02:18:22] <Sairon> in various machining roles, so at least the words make sense to me
[02:18:24] <jdhNC> don't let them find out
[02:18:39] <jdhNC> if they do, they will make sure to not ask you for any input.
[02:18:42] <Sairon> now, we're not machining
[02:18:50] <Sairon> but still, the ideas aren't that different
[02:18:52] <jdhNC> realism has no place in their world.
[02:21:00] <Sairon> well, good
[02:51:38] <ssi> I need to try to cut some pipe threads with emc
[02:51:53] <Danimal_garage> ahh, the old lean discussion

[03:07:58] <LikWidChz> anyone alive? i got a stupid question
[03:08:57] <A2Sheds> http://www.yikebike.com/ $2k, 1kw, 14mph, range 6 miles??
[03:09:43] <KimK> LikWidChz: Ask away
[03:09:54] <LikWidChz> do you know how big a 10/24 machine nut is?
[03:10:17] <jdhNC> about -> <- this big
[03:10:19] <LikWidChz> is it simply 10/24 = .41 inches or what not
[03:10:31] <LikWidChz> jdhNC whats your screen resolution ill do the conversion hahah
[03:10:36] <jdhNC> 10 is the size, 24 is threads per inch
[03:10:45] <LikWidChz> alright so 10 what?
[03:10:47] <A2Sheds> http://www.engineersedge.com/screw_threads_chart.htm
[03:11:05] <LikWidChz> Im not using them as nuts Im using them to tig the nuts together to make some little art stuff
[03:11:47] <A2Sheds> just #10, not ten of any standard measurement, they could have called it Bob-24
[03:12:00] <KimK> LikWidChz: I don't think it's ten of anything, just a number-ten size.
[03:12:22] <LikWidChz> yeah so it looks like on this chart its .19 inches
[03:12:44] <LikWidChz> http://cgi.ebay.com/Stainless-Steel-Hex-Machine-Finish-Nuts-10-24-500-pc-/110649665050?pt=LH_DefaultDomain_0&hash=item19c33be61a I wish they would just have a picture of a quarter next to it
[03:13:27] <A2Sheds> gauges are used for sizes of materials and fasteners, sheet metal, wire size, screws etc
[03:13:41] <LikWidChz> yeah what im looking for is what is the width of this nut
[03:13:55] <jdhNC> go measure one
[03:13:58] <LikWidChz> honestly I should just buy 1000 of these things http://cgi.ebay.com/3-8-Stainless-Steel-Nuts-25-per-pack-/140321564307?pt=LH_DefaultDomain_0&hash=item20abd12693
[03:14:00] <KimK> Also note that the hex outside dimensions are likely to be in multiples of 1/32 of an inch or so.
[03:14:19] <LikWidChz> so 10 32nds of an inch wide?
[03:14:42] <LikWidChz> no... thats 10 32nds of an inch wide inside diam of the threads
[03:14:49] <A2Sheds> it depends on the head, they are available in many types and sizes
[03:15:28] <KimK> I mean they are intended to fit nutdrivers and other tightening tools that (since we're talking English sizes here) are likely to fit tools that are in steps of 1/32 inch. So 7/32, 1/4, 9/32, 5/16, 11/32, etc.
[03:15:48] <LikWidChz> wow i wasnt thinking there
[03:15:59] <LikWidChz> everything should be metric..
[03:16:06] <jdhNC> why
[03:16:32] <LikWidChz> I like metric better hahah
[03:16:49] <jdhNC> even for time?
[03:16:56] <LikWidChz> ooh metric time
[03:17:04] <KimK> Well, it's certainly simpler in some cases, and you may have hit on one of them.
[03:17:04] <LikWidChz> an hour is actually 100 minutes :P
[03:17:06] <A2Sheds> metric alphabet
[03:18:02] <LikWidChz> hhaha the metric alphabet
[03:18:08] <jdhNC> 0 degrees is cold, 100 degrees is hot
[03:18:14] <LikWidChz> that sounds so retarded its a good idea
[03:18:16] <KimK> LikWidChz: I don't know what kind of an art project your making, but don't forget you'll have a hard time soldering stainless steel, if soldering is involved.
[03:18:24] <KimK> s/your/you're/
[03:18:29] <jdhNC> 0c isn't that cold, 100c isn't something you experience.
[03:18:45] <A2Sheds> http://snltranscripts.jt.org/75/75rdecabet.phtml can't find the video
[03:18:57] <LikWidChz> Kimk -- I have a tig
[03:19:29] <KimK> LikWidChz: OK. I hope it's a small one, or has a low current setting though.
[03:19:40] <jdhNC> #10 nuts are pretty small for welding
[03:19:53] <LikWidChz> my miller 200dx goes from 5-250 amps
[03:20:12] <LikWidChz> yeah jdhNC I found out that they are small nuts and wont work, ill just buy the 3/8ths inch ones
[03:24:40] <LikWidChz> http://img94.imageshack.us/img94/329/img8269v.jpg
[03:26:08] <jdhNC> ~9.3mm across flats, 316 stainless
[03:26:21] <A2Sheds> nice job for artwork
[03:26:37] <LikWidChz> I made a couple things like this, these are 1.5 inch nuts I made some stuff with smaller stainless ones
[03:26:52] <LikWidChz> Ill get a better photo
[03:27:32] <A2Sheds> most welding jobs I see on artwork is pretty sloppy
[03:28:54] <LikWidChz> yeah, well my cousin bought over 2 five gallon buckets of those nuts
[03:29:00] <LikWidChz> I went to town on them
[03:31:33] <LikWidChz> http://img546.imageshack.us/img546/4695/tigrobot.jpg
[03:31:37] <LikWidChz> thats what I made yesterday
[03:32:33] <elmo40> LikWidChz: looks like my ex... without her coffee in the morning :-P

[03:52:33] <nicko> I'm looking at the Mesa isolated I/O cards
[03:53:29] <nicko> 7i37 in particular - I have two more daughter card 'slots' - is one or possibly two 7i37 cards as simple as it gets ? or what are the other options ?
[04:01:13] <KimK> The 7i37's are very small, and they have the right balance of 24VDC I/O (more in than out, twice as many, in fact, 16 in and 8 out). If you think you might need to switch a mains-level AC voltage, the ribbon cable is compatible with any of Opto-22's 24-place (and some smaller) I/O cards. There are several available, and some clone makers.

[09:09:34] <automata_> I am trying a 3 axis mill with a Mesa 7i43 card. I have installed the live CD for and upgraded the install to emc 2.4.6. The default hm2-stepper configuration also works fine for me. Now I want to attach a hardware ESTOP button. But I am not sure what to change in the hal file to setup a hardware ESTOP button.
[09:10:34] <automata_> I realize that I will need to define a hardware input pin for the 7i43 using the num_dio option while loading the driver.
[09:11:54] <automata_> Also I will have to physically link up the estop-loop output to the new Input pin via a hardware ESTOP Button.
[09:12:07] <automata_> Any clues on where to start

[09:17:58] <Valen> did you use stepconf or do the config file yourself?
[09:18:27] <Valen> if its done your self, take a look for hal files around the place, somebody has an example of how to make an estop

[09:26:07] <automata_> I did the config mself.
[09:27:06] <automata_> Thanks, Valen, that is what I am trying now. Also looking at the pncconf wizard and trying to see if I can co-relate it's output to what I think should be happening.

[14:23:21] <automata_> does the M66 command support in-definite wait on input?
[14:24:32] <JT-Shop> I think it does if you don't use the Q word

[14:25:09] <JT-Shop> simple enough to test...

[15:11:26] <Connor> They're a bit tricky... You have to invert one of the enables to get them to work right.. because EMC only has 1 enable output, but, the board expects 3, so, You have to have a odd one in the mix to re-enable it.

[16:27:30] <automata_> I am using the Mesa 7i43 card with hostmot2 configuration to drive 3 steppers in a mill configuration.
[16:28:04] <automata_> I have set the W2 jumper on the 7i43 card to the "DOWN" position which means that the IO pins are operating at 3.3V
[16:28:56] <automata_> in the Mesa 7i43 manual it is mentioned that thsi is the standard method to connect the card.
[16:29:17] <automata_> the jumper W2 in the "UP" position would make the pins 5V tolerant
[16:30:30] <automata_> I would like to take external digital inputs like ESTOP and digital in. How should I configure the card? any pointers will help
[16:31:05] <automata_> I am also thinking about connecting opto-isolators for the inputs.

[16:50:23] <pcw_home> Much safer to leave the 7I43 in the default 5V tolerant mode
[16:51:35] <automata_> hi peter (pcw_home) (I assume you are Peter Wallace from Mesa)!
[16:52:02] <Danimal_garage> wowzers, just got some mouse traps and got 4 mice already
[16:52:11] -!- nullie [nullie!~nullie@nullie.telenet.ru] has joined #emc
[16:52:42] <automata_> I will change teh setup to 5V tolerant right away
[16:54:27] <pcw_home> Unless you need really fast signals with diode clamps to GND and VCC (non motion control uses)
[16:54:29] <pcw_home> I would use 5V tolerant mode
[16:58:24] <automata_> I have put the W2 Jumper to the Up Position. The W3 jumper is also in the Up position. However int he manual it says that the W3 jumper providesa 3.3V pullup for all user-configured io pins.
[16:59:04] <automata_> will this be a problem when inputs are connected to 5V supply?
[16:59:47] <pcw_home> I wold normally just leave the jumpers in the default positions for example ,all of our daughtercards require 5V on pin 49
[17:01:56] <pcw_home> Fo opto inputs i would use the built in pullups, and pull the inputs down with the OPTO
[17:01:58] <pcw_home> make sure you use a standard OPTO, not Darlington as their saturation voltage is too high for a good TTL low
[17:02:03] <pcw_home> For
[17:02:08] <automata_> The manual for the 7i43 shows the Defaultposition of W2 as "Down". That is what got me confised.
[17:02:38] <pcw_home> Thats an error in the manual (I will fix today(
[17:02:54] <automata_> Thanks.
[17:03:16] <automata_> Peter: Do you ahve a rep in India?
[17:03:26] <pcw_home> No
[17:03:33] <automata_> I would like to get some 7i33
[17:04:45] <automata_> If you ar echanging the manual: can you put a default jumpers section too. Not just teh default diagram but also some text detailing the default position.
[17:06:21] <automata_> I have the setup working with W1,W2,W3 in "UP" positions.
[17:06:33] <automata_> Now for some opto-isolation.

[17:32:57] <automata_> i will look for that config right away...
[17:33:34] <skunkworks> I would think you could.. just never thought about it. My config is pretty complicated - so ladder was a must

[17:53:02] <automata_> the external pin input does operate the estop pin. But the estop out behaves in a wierd fashion.
[17:54:13] <atom1> net estop-loop hm2_[HOSTMOT2](BOARD).0.gpio.015.in => iocontrol.0.emc-enable-in
[17:54:50] <skunkworks> ^ that would be very basic setup - only the external estop will enable emc.
[17:55:30] <automata_> That is exactly what I have setup right now.
[17:56:00] <automata_> In this config what happens to the internal estop signal output?

[17:56:56] <Zencncbuild> maybe stupid question but i am wiring up my XYZ limit stops and E stop i have one pin for each + GND, i assume the right thing to do is to connect all of them to the one GND pin + separate pins for each switch ?
[17:57:19] <Tom_itx> good idea
[17:57:32] <Zencncbuild> the thing is when GND'ed it all stops ? :)

[18:47:49] <Danimal_garage|2> 73 and back mustangs used the same lug pattern i think. you can get some old school cragars or something
[18:48:03] <jdhNC> looks fine for what it is (which isn't really a mill)
[18:48:03] <Loetmichel> some people are not shy to rip off people without hesitating... :-(
[18:48:16] <Loetmichel> jdhNC: looked on the pricetag?
[18:49:09] <skunkworks> Tom_itx: I think the issue with that estop setup is that if I hit the external estop - and then reset it - the machine comes out of estop. I like having to click the estop in axis to bring the machine back up.
[18:49:12] <jdhNC> I see no price

[18:49:33] <Danimal_garage|2> those are stock ranger wheels, they come in 14" and 15" and don't look half bad
[18:49:35] <archivist> jdhNC, 899 euro
[18:49:51] <anonimasu> skunkworks: cant you unlink the axis estop and use a AND to force both to be set
[18:49:58] <Danimal_garage|2> aluminum
[18:50:00] <anonimasu> and force toggling the axis on with a comp of your own?
[18:50:09] <Loetmichel> for metric screws instead of ballscrews or even trapezoid ... no backslash compensation (only one nut per sled), thin round bars instead of supported rails. a 17" plywood as groundplate...
[18:50:09] <anonimasu> like a latch?
[18:50:27] <jdhNC> ok, that's a little excessive... a little more than my mill cost
[18:51:05] <skunkworks> anonimasu: If you don't want to use classic ladder - then you would have to come up with something in hal. I am sure it could be done. I see there is an estop comp that may do just that.
[18:51:11] <jdhNC> but, hey, germans are rich. They can afford it
[18:51:11] <archivist> Loetmichel, nasty flexible heap for too much money...but made in germany he says!
[18:51:26] <skunkworks> anonimasu: I use rung 4 http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Sample_HAL_And_ClassicLadder
[18:51:32] <Danimal_garage|2> classicladder is fun once you learn it. I suggest giving it a try
[18:51:43] <Danimal_garage|2> if my slow ass could figure it out, anyone can :)
[18:52:04] <Loetmichel> archivist: my fist CNC was build with metric screws...
[18:52:24] <skunkworks> :) I equate it to learning eagle... Once you figure out the oddities of the interface - it is pretty easy.
[18:52:31] <Loetmichel> the nuts (2 per sled for bachslash comp.) lasted about 8h
