[00:00:18] <anonimasu> still, funny..
[00:00:31] <les> For me ... I took the plunge and will attempt sharpening solid carbide spiral router bits
[00:00:39] <anonimasu> cool
[00:00:40] <anonimasu> :)
[00:00:54] <les> Bought some awfully expensive diamond gring wheels today
[00:01:09] <les> grinding
[00:01:42] <les> I am getting about 6 hrs from some tools
[00:02:11] <les> sending them off for sharpening is a problem...40 km drive to mail them
[00:02:23] <anonimasu> hmm wood seems though
[00:02:26] <anonimasu> err tough..
[00:02:33] <les> So I will try it
[00:02:39] <anonimasu> * anonimasu has no experience in milling wood
[00:02:41] <anonimasu> machining
[00:02:46] <anonimasu> just some MDF..
[00:02:49] <anonimasu> or similiar
[00:02:54] <les> cherry
[00:03:04] <anonimasu> but that's not even real wood :)
[00:03:13] <les> but 6 hrs makes 100 kg of chips or so
[00:03:17] <anonimasu> hehe
[00:03:54] <les> actually I probably shoud not even bother with sharpening
[00:04:01] <les> I am just cheap
[00:04:09] <les> tool bit is $50
[00:04:29] <gezr> question about bearings, if I was able to knock a bearing out, using but a small block of aluminum, could that damage the bearing?
[00:04:32] <anonimasu> but mailing em is pretty annoying
[00:04:37] <anonimasu> :)
[00:04:39] <anonimasu> isnt it?
[00:04:47] <les> $9 for tool wear
[00:04:59] <jmkasunich> gezr - depends on which race you were pounding on
[00:05:02] <les> per hr
[00:05:27] <gezr> jmkasunich : it was protected outer race, I had to do my best with care on the inner
[00:05:44] <jmkasunich> another way to look at it - if you can resharpen in 20 mins, you are making $150/hr sharpening
[00:06:01] <gezr> it doesnt feel as if it is damaged, but I probably should look at replacement just to be sure hu?
[00:06:17] <anonimasu> gezr: what's the bearing for?
[00:06:22] <jmkasunich> depends on how critical a bearing it is, and how expensive the replacement
[00:06:33] <les> Gezr: if inner race is press fitted (as is normal for a shaft) you must only press on that
[00:06:50] <gezr> its just a load supporting bearing, for the alternator connection
[00:07:02] <les> Some tools require you to press on the outer
[00:07:15] <les> which destroys the bearing
[00:07:15] <anonimasu> oh I dont think you should worry that much
[00:07:17] <anonimasu> about it..
[00:07:18] <anonimasu> :)
[00:07:18] <gezr> yeah I know whats available, I dont ahve the tools
[00:07:24] <jmkasunich> I believe the shaft was already out, and he was removing the bearing from the housing?
[00:07:30] <gezr> yep
[00:07:42] <les> but they figure you wouldn't be removing it if it wasn't bad already
[00:07:43] <gezr> It didnt require much force, or beating
[00:08:20] <gezr> I had to get it out because of contamination from when I pulled the inbound side of the alternator coupling
[00:08:32] <les> Well, if it's brinnelled you will hear it
[00:10:41] <jmkasunich> gezr... do decide whether to replace... compare the cost of the replacement bearing with the effort to replace it later. If you have to tear the whole engine apart to get at it, and the bearing is cheap, then replace it anyway, just to be sure.... if it's expensive, but easy to get at, then go ahead and use the old one, if it turns out to be bad you can replace easily
[00:11:05] <les> good plan
[00:11:12] <anonimasu> yep
[00:11:28] <gezr> yeah im trying to look it up, I had to pull the connecting part to get at the guts of the motor, it doesnt appear to be fancy
[00:14:42] <anonimasu> * anonimasu yawns
[00:14:54] <les> I am hungry
[00:15:01] <les> dinnertime here
[00:15:09] <les> I will do that
[00:15:18] <les> later!
[00:15:21] <jmkasunich> * jmkasunich just had a large burrito
[00:15:28] <les> mmmm
[00:20:00] <anonimasu> I'll be heading off to bed now
[00:20:04] <anonimasu> :)
[00:20:31] <jmkasunich> goodnight
[00:21:02] <anonimasu> goodnight
[00:24:39] <gezr> 7 buck bearing :)
[00:25:53] <jmkasunich> replace it :)
[00:26:07] <gezr> oh yeah :)
[00:26:16] <gezr> http://mdmetric.com/pdf/brgprice2.pdf
[00:26:21] <gezr> huge list of bearings and prices
[00:32:48] <robin_sz> coo
[00:32:55] <robin_sz> do I read that right?
[00:33:15] <robin_sz> jmkasunich just eat a large donkey?
[00:33:56] <jmkasunich> nopw
[00:33:59] <jmkasunich> nopw
[00:34:01] <jmkasunich> nope
[00:34:09] <jmkasunich> dammit, kant spel
[00:34:14] <robin_sz> whats a burrito then?
[00:35:27] <gezr> your thinking burro robin_sz, its a tortillia filled with meat or beans or both or whatever
[00:35:35] <robin_sz> ahh.
[00:35:38] <jmkasunich> pile o stuff, wrapped in totilla
[00:35:57] <robin_sz> damn you all!
[00:36:03] <robin_sz> now I feel hungry :)
[00:36:13] <robin_sz> and its 1am
[00:36:14] <jmkasunich> in my case, shredded port, black beans, sauteed onions and green pepper, salsa, sour cream, and cheese
[00:36:17] <robin_sz> grrr :)
[00:36:27] <jmkasunich> shredded porK
[00:36:42] <robin_sz> oh ;) I was trying to work out how to shred pork
[00:36:47] <robin_sz> port
[00:36:52] <robin_sz> damn, yo uhave me at it now
[00:37:09] <robin_sz> sounds nice, apart from the pork
[00:37:32] <jmkasunich> they also had spicy beef, or chicken
[00:37:48] <robin_sz> too beefy and chickeny :)
[00:38:16] <jmkasunich> and veggie, with beans and guacomole
[00:38:22] <jmkasunich> I don't like guac
[00:38:29] <robin_sz> mmmmm ... gimme
[00:38:51] <robin_sz> im begininning to dislike this poxy rabbit thing
[00:39:04] <jmkasunich> green gooey stuff, ick
[00:39:12] <jmkasunich> guac that is, not the rabbit
[00:39:16] <robin_sz> they shipped an ancient copy of the IDE
[00:39:30] <robin_sz> not returned my calls
[00:39:48] <robin_sz> and the US office hasn't responded to my email
[00:40:01] <robin_sz> now im pi55ed.
[00:40:19] <jmkasunich> isn't the rabbit a Z80 variant?
[00:40:24] <jmkasunich> is there a gcc for Z-80
[00:40:29] <robin_sz> vaguely
[00:40:38] <robin_sz> its not a z80
[00:40:49] <robin_sz> has rather specific codeset and loading process
[00:40:55] <robin_sz> you need their tools basically
[00:41:23] <robin_sz> I do hope the V9.x IDE is better than the 7.x they shipped, because that sucks
[00:41:49] <robin_sz> can you imagine a compiler where you cant set the include path?
[00:46:56] <robin_sz> whatever, im whining
[00:48:20] <jmkasunich> isn't that what IRC is for?
[00:52:47] <robin_sz> guess so ...
[01:35:27] <jmkasunich> fscking winblows IE exploits !@$@!$#@#%
[01:36:23] <gezr> ?
[01:36:53] <jmkasunich> I have a doze box here I use for some things that I don't have good linux SW for
[01:37:03] <jmkasunich> last night it got infected
[01:37:29] <jmkasunich> "elite toolbar", a internet explorer "add on" that installs itself and is bloody murder to get rid of
[01:37:45] <jmkasunich> up till three am trying to get rid of it, and it seems bits are still around
[01:42:04] <jmkasunich> mix of old and new: http://home.att.net/~jmkasunich/Pics/radio_server.jpg
[01:55:00] <rayh> Is there a working site to download 4.14?
[01:57:08] <jmkasunich> sherline?
[01:57:24] <rayh> It's down right now.
[01:57:29] <rayh> Hi John.
[01:57:33] <jmkasunich> hi ray
[01:58:01] <jmkasunich> ISTR a post from Paul recently that mentioned a couple mirrors
[02:00:15] <jmkasunich> you trying to DL a copy?
[02:00:46] <rayh> Got a friend who is.
[02:04:24] <jmkasunich> wiki to the rescue:
[02:04:25] <jmkasunich> http://www.redpoint.org.uk/cgi-bin/emcinfo.pl?BrainDeadInstall
[02:04:29] <jmkasunich> has the mirrors
[02:10:38] <rayh> did you get a chance to look at the wiki?
[02:10:59] <jmkasunich> a little on sunday (even added a page)
[02:12:00] <rayh> I put in just the start of a glossary today. Mostly for the format of how to do it.
[02:13:27] <rayh> I think that we are about ready to post a note regarding it to the user list.
[02:16:24] <jmkasunich> yeah
[02:16:44] <jmkasunich> you ever do any ham radio stuff Ray?
[02:18:30] <rayh> Long years ago. Think I was ten or so.
[02:19:20] <rayh> Two of the guys in the radio repair shop I worked at were amateur extra class. Only 45 of those licenses then.
[02:19:43] <rayh> What are you thinking about ham radio?
[02:19:52] <danfalck> hi guys
[02:20:01] <rayh> Hi Dan.
[02:20:07] <jmkasunich> I'm about to start an ebay auction for my father-in-law's Hallicrafters S-85 SW receiver
[02:20:29] <rayh> Oh. Nice box.
[02:20:41] <danfalck> Ray, check out the web page I did about Hal May. It's in the wiki under case studies.
[02:20:50] <rayh> K
[02:21:08] <danfalck> It's my first web page...
[02:22:18] <rayh> Getting it now.
[02:22:39] <jmkasunich> seems a little wonky here, that might be a geocities thing
[02:22:54] <danfalck> what's it doing?
[02:23:00] <jmkasunich> better now...
[02:23:19] <jmkasunich> while loading the page, it put multiple photos and text all on top of each other
[02:23:26] <jmkasunich> but it cleared up once it finished loading
[02:23:40] <rayh> There is a frenchman in Portland who is very interested in EMC. Offered to translate stuff for us.
[02:23:59] <danfalck> really?
[02:24:12] <jmkasunich> hmm, many of the pics didn't show up
[02:24:27] <danfalck> oh oh...
[02:24:39] <jmkasunich> last one that worked was "Hal showing off EMC"
[02:24:45] <danfalck> that's strange...
[02:24:51] <rayh> I'm still watching bits dribble down the phone line.
[02:25:13] <danfalck> seemed to work on my wife's computer a minute ago.
[02:25:19] <jmkasunich> lemme try with Mozilla, Konqueror sometimes does strange stuff
[02:25:41] <danfalck> I use safari, she uses mozilla (firefox)
[02:26:40] <jmkasunich> uh-oh
[02:26:46] <danfalck> ?
[02:26:53] <jmkasunich> Sorry, this site is temporarily unavailable! The web site you are trying to access has exceeded its allocated data transfer.
[02:27:07] <danfalck> oh noooooo....
[02:27:18] <danfalck> I'll look for another site....
[02:27:25] <jmkasunich> I didn't think Ray and I were enough to count as a slashdotting ;-)
[02:27:58] <danfalck> that's funny. let's see, you, Ray, myself, and my wife slashdotted it : 0
[02:28:27] <rayh> That must be a busy server.
[02:28:29] <jmkasunich> well, it's geocities.....
[02:28:59] <rayh> If you sent the images to robin z you could put the page right in the wiki.
[02:29:24] <rayh> I did that with a couple images last night.
[02:30:14] <danfalck> ok, I'll do that.
[02:30:32] <danfalck> thanks for checking it out for me
[02:30:34] <rayh> Let me get the address he sent me.
[02:31:09] <rayh> holding@redpoint.org.uk
[02:31:34] <danfalck> is there any way to ftp the stuff to his server that you know of?
[02:31:57] <rayh> No but you could ask him.
[02:32:35] <rayh> He should be around by the time you get going in the morning. Or on the weekend.
[02:33:14] <rayh> You could tar it all up and put on linuxcnc and he could get it there.
[02:33:41] <danfalck> ok. i'll try that
[02:35:12] <rayh> Hal does some fantastic work.
[02:35:28] <rayh> I like your shots and text. Good site.
[02:36:11] <danfalck> paul is going to be here this weekend
[02:36:16] <rayh> gotta run. Maxine is calling. Catch you all later.
[02:36:26] <rayh> Hey that's great.
[02:44:54] <danfalck> gotta go...
[03:28:06] <gezr> im tired,
[03:28:13] <gezr> you guys have a great night/day
[03:29:47] <asdf-meep> asdf-meep is now known as asdfqwega
[05:33:29] <dave-e> dan are you around?
[05:33:36] <dave-e> awake?
[05:35:48] <dave-e> anyone have an email address for dan falck?
[06:11:51] <danfalck> dave:yea
[06:12:01] <dave-e> hey...it talks
[06:12:06] <danfalck> yep...
[06:12:16] <danfalck> I'm playing w/ python
[06:12:28] <danfalck> the programming language not a snake
[06:12:33] <danfalck> ;)
[06:12:35] <dave-e> oh, ugh...neat stuff if you think that way
[06:12:50] <danfalck> what are you up to tonight?
[06:13:00] <dave-e> I'm too procedural
[06:13:09] <dave-e> been looking at the wiki
[06:13:28] <dave-e> and plotting next moves for the mazak.
[06:13:45] <dave-e> just got my stg board back and now have x, y and z working
[06:13:51] <danfalck> cool
[06:13:55] <dave-e> need to tune, etc.
[06:14:10] <danfalck> paul might be here this weekend
[06:14:12] <dave-e> then figure out tool table ...
[06:14:19] <dave-e> oh really.
[06:14:38] <danfalck> yes. I invited him up to stay at my place for a couple days if he wants
[06:14:44] <dave-e> do you deal with the people at pacific machinery and tool steel?
[06:15:21] <danfalck> no but they are just down the street from us
[06:15:47] <dave-e> I have a good working relationship with Brad, the metallurgist
[06:15:57] <dave-e> he has been really nice and helpful
[06:16:15] <dave-e> so where are you?
[06:16:33] <danfalck> I work in the NW industrial district of Portland
[06:16:38] <danfalck> but live in Beaverton
[06:16:39] <dave-e> address?
[06:16:52] <danfalck> work or home?
[06:16:58] <dave-e> ah..but close to the brewery ... right.....work
[06:17:11] <danfalck> yes really close to the brewery
[06:17:27] <danfalck> I eat at Guilds Lake Inn all the time
[06:17:59] <dave-e> stumbled on to the brewery for lunch one noon with a local friend....the girls won't believe it was an accident
[06:18:00] <danfalck> we are off of 29th on NW Nela
[06:18:22] <dave-e> I suppose I could find that with a little help.
[06:18:30] <dave-e> some of the area is a rabbit warren
[06:18:30] <danfalck> How far are you from portland?
[06:18:43] <dave-e> Selah....180 mi or so
[06:18:47] <danfalck> ok
[06:18:55] <dave-e> 3 hr +
[06:19:39] <dave-e> only other place down there that I use is Stack ... for heat treating
[06:19:39] <danfalck> what are you doing w/ the Mazak?
[06:19:51] <danfalck> we use Stack every week too
[06:19:55] <dave-e> well the plan is to make gun parts....
[06:19:56] <danfalck> great company
[06:20:21] <dave-e> first is a CF conversion block for the Spencer
[06:20:50] <dave-e> next is the forward breechblock for the Starr carbine
[06:21:25] <dave-e> after I get a sample made it will show up on my web page...and the wiki will point to it.
[06:21:36] <danfalck> great
[06:21:56] <dave-e> what products does your company make?
[06:22:31] <danfalck> bearings for bicycles and a lot of the stuff that the bearings go int
[06:22:41] <danfalck> headsets, hubs
[06:22:45] <danfalck> cogs
[06:23:01] <dave-e> oh, all the good stuff, steel or Ti
[06:23:10] <danfalck> steel, Ti, aluminum
[06:23:25] <dave-e> what alloy for each?
[06:23:40] <danfalck> I'm not sure I can say over IRC
[06:23:46] <dave-e> oh, OK
[06:24:04] <danfalck> it's a fun process though. I really enjoy it now
[06:24:18] <danfalck> I came from the woodworking business-Gibson Guitar
[06:24:26] <danfalck> enjoyed that too
[06:24:46] <dave-e> Boeing is pretty much just doing assembly in WA at this point, which means that the good sources of Al are going away.
[06:24:59] <danfalck> I design tools, fixtures, work on processes
[06:25:12] <danfalck> yep, suppliers are going offshore
[06:25:20] <dave-e> I'm going to miss the 7050 and 7075 T651
[06:25:40] <danfalck> what a shame
[06:26:29] <danfalck> do you make gun parts for a hobby or a living?
[06:26:33] <dave-e> I've got a pretty good stock of 4041, 4043 and some tool steels from the shorts rack at Summerville in Seattle
[06:27:18] <dave-e> I've been retired for 12 years now. Gun parts are supposed to be a hobby...and if it happens to make some $$ that is all the better
[06:27:37] <danfalck> what did you do before retiring?
[06:27:44] <dave-e> ag chemist
[06:27:52] <danfalck> wow
[06:28:14] <danfalck> did you work around the country?
[06:28:17] <dave-e> actually a microbiologist by degree but a strong chem minor....30 sem hours
[06:28:20] <dave-e> no ....
[06:28:31] <danfalck> washington state?
[06:28:59] <dave-e> grad from WSU...got drafted...spent two years in Utah....dugway proving gnd...
[06:29:24] <dave-e> doing plague survey and then working on chemical tracers for bio-systems.
[06:29:50] <dave-e> then two years back at wsu ... doing C14 and H3 dating
[06:30:04] <dave-e> then came to Yakima and I'm still here
[06:30:40] <danfalck> are you up in the higher elevations? get more snow ?
[06:30:52] <dave-e> did some fun stuff...PDP-11 data acq for an atomic absorbtion
[06:31:04] <dave-e> 900' no much snow
[06:31:09] <dave-e> not
[06:31:53] <danfalck> hey, earlier you mentioned Boeing not making their own parts here anymore...you want to hear a funny story?
[06:32:06] <dave-e> we've had a 55 degree day with sun
[06:32:09] <dave-e> sure
[06:32:46] <danfalck> Thanksgiving 2003, I was having turkey with my family at some friends place in Sonoma, Ca
[06:32:54] <danfalck> there were a lot of people there
[06:33:04] <danfalck> lots of couples from Seattle
[06:33:20] <danfalck> the couple that had us over were origianlly from Seattle
[06:33:38] <danfalck> One couple there, the husband was retired from Boeing
[06:33:49] <danfalck> He was one of the head bastards in purchasing
[06:34:05] <danfalck> He asked me what I did, where I worked
[06:34:09] <danfalck> told him
[06:34:26] <danfalck> we just about got into a fight about manufacturing
[06:34:39] <danfalck> He kept on me most of the night
[06:35:00] <danfalck> about how we were crazy for trying to make things in this country anymore
[06:35:23] <danfalck> I told him that we made 'everything' in house and he could go stick it
[06:35:34] <danfalck> It was hilarious
[06:35:44] <danfalck> I'm just glad that my boss wasn't there
[06:35:52] <danfalck> there would have been a fist fight...
[06:36:22] <dave-e> well purchasing people are often accountants...nuf said
[06:36:35] <danfalck> I was glad he didn't show up this last thanksgiving
[06:36:41] <dave-e> indeed
[06:36:59] <danfalck> anyway...
[06:37:07] <danfalck> I just had to tell that one
[06:37:32] <dave-e> 'course Boeing did the duh thing of moving corporate to Chicago... of all places
[06:38:00] <danfalck> I came from the midwest and wouldn't ever go back
[06:38:06] <dave-e> on top of that they seem to be working toward only the mil stuff forget commercial
[06:38:58] <dave-e> I don't understand why anyone would move from the NW to Chicago...of course a lot of them didn't
[06:39:20] <danfalck> maybe something was .02 cheaper there
[06:39:21] <dave-e> anyone that could afford to get out did.
[06:39:42] <dave-e> part of it is driven by the merger
[06:39:58] <danfalck> mcdonald?
[06:40:11] <dave-e> I heard you cannot make it to fest....darned
[06:40:18] <dave-e> yes
[06:40:21] <danfalck> not enough vacation days
[06:40:26] <dave-e> opps.
[06:40:37] <dave-e> but then one cannot have everything
[06:40:55] <danfalck> paul will be here this week. It could kind of be like fest
[06:41:00] <dave-e> indeed
[06:41:18] <dave-e> you can pick his brain
[06:41:24] <danfalck> should I interview him and take lots of pics?
[06:41:36] <danfalck> BDI star
[06:41:45] <dave-e> just work on your problems
[06:41:59] <danfalck> threading for the lathe is what I want
[06:42:04] <dave-e> maybe pick his brain about threading
[06:42:22] <danfalck> I just want to see EMC do well
[06:42:24] <dave-e> I need that also
[06:42:59] <danfalck> are you going to fest then?
[06:43:17] <dave-e> I'm hoping to get some stuff up on my machine...don't know of anyone running a Mazak with emc
[06:43:50] <dave-e> Ray has cornered me into coordinating some of the integration stuff at cardinal eng
[06:44:47] <dave-e> first thing to do is work on getting a machine to convert
[06:45:09] <danfalck> something other than the Mazak?
[06:45:11] <dave-e> I'm hoping for a BP-I or BP-II
[06:45:45] <danfalck> I've seen a couple here in town in the last 6 months
[06:46:02] <danfalck> I'll keep watching for you
[06:46:09] <dave-e> it should have all the limit switches in place, estop, servo motors, ...which leaves power supply, amps and control
[06:46:32] <dave-e> cardinal engineering does this pretty regularly...so they may have a machine
[06:47:06] <dave-e> machines out here are much more expensive than in the midwest where they almost throw them away.
[06:47:48] <danfalck> do you have any of John Elson's boards?
[06:47:55] <dave-e> just getting that much done in a week will be a challenge
[06:47:59] <dave-e> ppmc
[06:48:12] <danfalck> is that the stepper pulse generator?
[06:48:26] <dave-e> no ... the encoder/dac/io
[06:48:36] <danfalck> does it work well?
[06:49:14] <dave-e> when I can get it to work.,..it works very well.
[06:49:23] <danfalck> parport problems?
[06:49:27] <dave-e> I keep burning the chip
[06:49:40] <danfalck> the chip in the ppmc?
[06:50:03] <dave-e> paraport works fine. Jon's test stuff no tests for paraport which really helps
[06:50:33] <dave-e> yep...the Xilinux chip on the board...only the dac board tho
[06:50:58] <dave-e> Jon says I have a grounding problem.
[06:51:29] <danfalck> I'm interested in his step generator board
[06:51:31] <dave-e> I used the short system...no i/o two summers ago...on a single axis test bed...
[06:52:16] <dave-e> MT-30 servo...70 v supply...2" flywheel on the motor shaft...encoder
[06:52:43] <dave-e> at 400 ipm...with accel of 1 g
[06:52:51] <danfalck> wow
[06:53:13] <dave-e> the stepper pulse dispensing board should work well
[06:53:26] <danfalck> the price is right also
[06:53:43] <danfalck> just can't afford one right now though
[06:54:17] <dave-e> I've used a ISA parallel port ....and the paraport on a 1.2 gig shuttle board/Duron with no problems
[06:54:33] <dave-e> the isa was an add on board
[06:54:38] <danfalck> w/ ppmc?
[06:54:43] <dave-e> yep
[06:55:10] <dave-e> any old machine really doesn't do a good job of epp
[06:55:52] <dave-e> Jon says the newer pci parallel ports are pretty good
[06:57:38] <dave-e> I'd better run....a long list of things to get done tomorrow
[06:57:58] <danfalck> good chatting with you
[06:58:04] <dave-e> catch you later
[07:36:22] <anonimasu> good morning
[08:28:19] <kb1_kanobe> evening all.
[08:34:15] <kb1_kanobe> Just reading about EMC and wondering how the... err... "post-processors" are implemented. Ie. how does the job get from CAD to controlled motions when switching between, say, a mill with a quill feed and a mill with only Z-axis through table motion.
[08:34:33] <alex_joni> hello
[08:34:38] <kb1_kanobe> hello.
[08:34:43] <alex_joni> the "post-processors" are part of the CAM software
[08:34:48] <alex_joni> not part of EMC
[08:35:09] <alex_joni> EMC expects a NC-file (RS274 or g-code)
[08:35:11] <kb1_kanobe> Ah... so the CAM must be aware of the target machine - eg. hexapod mill vs. 3-axis.
[08:35:15] <alex_joni> yes
[08:35:23] <alex_joni> hmmm.. not really
[08:35:29] <alex_joni> that's debateable
[08:35:40] <alex_joni> the CAM must be aware of the capabilities of the machine
[08:35:52] <alex_joni> e.g. mill vs. lathe or plasma
[08:35:57] <kb1_kanobe> and generates the optimum toolpath for it. Makes sense.
[08:35:58] <alex_joni> 2 axis or 3 axis
[08:36:17] <alex_joni> emc expects a nc-file with standard XYZABC coordinates
[08:36:25] <alex_joni> which can be XY, XYZ, etc...
[08:36:42] <alex_joni> and it does the kinematics based on the machine (hexapod is one example)
[08:37:06] <kb1_kanobe> ok... I guess I just need to install it and play :-)
[08:37:14] <alex_joni> what are you planning to install?
[08:37:20] <alex_joni> emc1/emc2 ?
[08:37:25] <alex_joni> what kernel?/ BDI?
[08:37:27] <kb1_kanobe> erm, BDI iso.
[08:37:32] <alex_joni> which one? ;)
[08:37:41] <alex_joni> I am only asking to keep you from later trouble
[08:37:52] <kb1_kanobe> BDI-Live_rc46.iso
[08:38:00] <alex_joni> ok, that one's perfect
[08:38:05] <kb1_kanobe> phew!
[08:38:17] <alex_joni> there is a new one out (bdi-4.14) but ... ;)
[08:38:39] <alex_joni> but that one's 2.6 based
[08:38:54] <alex_joni> and you won't be able to get the CVS source and compile it
[08:39:01] <alex_joni> IF you want to do that ;)
[08:39:11] <kb1_kanobe> No worries. Just want to putter for now.
[08:39:12] <kb1_kanobe> So - I see lots of stepper-related information for emc. How about DC servo control and/or hydraulic?
[08:39:37] <alex_joni> well.. there are some boards supported to do servo control
[08:39:47] <alex_joni> ServoToGo, Motenc,
[08:40:02] <kb1_kanobe> Could I go shopping for a Compumotor drive system and interface emc to that reasonably (via RS232)?
[08:42:00] <anonimasu> hey alex
[08:42:18] <anonimasu> and hi kb1_kanobe
[08:42:24] <kb1_kanobe> hello anonimasu.
[08:42:37] <kb1_kanobe> Thanks for the information alex, that clears things up a but for me.
[08:42:43] <anonimasu> what cam package are you using kb1_kanobe ?
[08:43:07] <kb1_kanobe> Nothing yet :-)
[08:43:11] <alex_joni> kb1_kanobe: rs232 is something you can do, but is not done yet
[08:43:17] <alex_joni> you might get help in doing it ;)
[08:43:18] <anonimasu> I am curious because I'll be making a post for visualmill later this week..
[08:43:18] <anonimasu> :)
[08:43:29] <anonimasu> and eventually mastercam but that one's far away.
[08:43:32] <alex_joni> what machine you want to control?
[08:43:37] <alex_joni> * alex_joni likes sheetcam ;)
[08:43:47] <alex_joni> but it's only 2D for plasma/oxy-fuel
[08:43:54] <anonimasu> yeah :)
[08:44:22] <kb1_kanobe> I have a Cincinnatti Mill I was considering retrofitting for handling repetative operations.
[08:44:22] <anonimasu> what size of cutter do you use when engraving nametags?
[08:44:46] <anonimasu> I'll get cutters off work if I engrave nametags for all store employees..
[08:44:53] <anonimasu> good deal..
[08:51:05] <anonimasu> :)
[08:51:21] <anonimasu> I think I'll finish the mill on the afternoon
[09:05:06] <alex_joni> hey an0n
[09:05:10] <alex_joni> at work?
[09:05:19] <anonimasu> yeah
[09:05:32] <anonimasu> but I might take the afternoon off to finish the mill
[09:05:34] <alex_joni> cool..
[09:05:40] <anonimasu> :)
[09:05:43] <alex_joni> that means you're feeling better.. ?
[09:06:12] <anonimasu> a bit.. it's rheumatism so it goes from good to bad..
[09:06:21] <alex_joni> ouchy... :/
[09:10:00] <anonimasu> hm, I wonder if I could just use a small drill for engraving
[09:12:48] <anonimasu> how's it going with your work?
[09:13:06] <anonimasu> I am mostly waiting for a solution off the PLC manufacturer..
[09:13:56] <alex_joni> at work it's ok
[09:14:04] <alex_joni> I finished installing two robots
[09:14:16] <alex_joni> gotta program the welding now (that's gonna be a bit tricky)
[09:14:26] <anonimasu> :)
[09:16:13] <anonimasu> I've got loads of problem with using PWM off the plc.. the pulsewidth increases lots over 0.1%.. but that's a bug..
[09:16:38] <alex_joni> 0.1% ?
[09:16:48] <anonimasu> yeah :)
[09:16:56] <alex_joni> kinda slow .. ain't it?
[09:17:05] <anonimasu> the voltage increases from 11.52v to 17v
[09:17:09] <anonimasu> slow?
[09:17:18] <anonimasu> that's 0.1% of 125hz ;)
[09:17:31] <alex_joni> you're doing PWM at 125 Hz ?
[09:17:34] <anonimasu> yeah
[09:17:37] <alex_joni> ouchy
[09:17:41] <anonimasu> howcome?
[09:17:45] <alex_joni> don't wanna know how the motor feels
[09:17:52] <alex_joni> PWM is usually at kHz range
[09:18:01] <anonimasu> I dont run motors.. I run a huydralic valve..
[09:18:07] <alex_joni> ahhh.. ok then
[09:18:19] <alex_joni> is it a close/open valve?
[09:18:21] <anonimasu> they require a frequency about 100hz..
[09:18:25] <alex_joni> or one you can adjust ?
[09:18:25] <anonimasu> a proportional one
[09:18:29] <anonimasu> yeah
[09:18:37] <alex_joni> did you try higher PWM rates?
[09:18:41] <alex_joni> it should work smoother
[09:18:44] <anonimasu> yeah.. it's a bug.
[09:18:55] <anonimasu> I measured it at the scope..
[09:19:18] <alex_joni> I agree.. but still it's kinda low for PWM
[09:19:27] <alex_joni> I ran PWM on a H-Bridge
[09:19:32] <alex_joni> and ran it about 17kHz ;)
[09:19:38] <alex_joni> off a 80C51 :P
[09:20:11] <anonimasu> :)
[09:20:46] <alex_joni> I ran it slow too
[09:20:53] <alex_joni> but that would have killed the motor
[09:21:20] <alex_joni> how did you come up with 100Hz frequency for the valve (datasheet?)
[09:21:21] <anonimasu> at the forest machines they run at 100hz.. precisely..
[09:21:28] <anonimasu> and it's the same valve :)
[09:21:38] <anonimasu> and they are super precise...
[09:21:55] <alex_joni> depends on the counter you use
[09:22:07] <alex_joni> if you have a big counter at high speeds
[09:22:14] <alex_joni> or a small counter at low speeds
[09:22:18] <alex_joni> you get the same precision
[09:22:30] <alex_joni> big counter at low speeds ... better precision
[09:23:02] <anonimasu> it
[09:23:09] <anonimasu> yeah
[09:23:20] <anonimasu> but well, as soon as they solve the bug with this i'll be set :)
[09:23:24] <alex_joni> yup
[09:23:42] <alex_joni> if the valve/motor supports it it's ok to go at low speeds
[09:23:47] <anonimasu> yeah..
[09:23:50] <alex_joni> at higher speeds you have better integration
[09:23:54] <anonimasu> the valves are built for that frequency..
[09:24:06] <anonimasu> so it's not a problem..
[09:24:13] <alex_joni> so the motor/valve won't know it's running off a chopped signal
[09:24:21] <alex_joni> ahh.. ok then ;)
[09:24:25] <anonimasu> yeah, but it's built that way..
[09:24:26] <anonimasu> :)
[09:24:50] <anonimasu> you run about 100hz to control the proportional valves..
[09:25:39] <alex_joni> seems jmk was in last night
[09:26:18] <anonimasu> yep
[09:26:30] <alex_joni> bugger.. I missed him ;)
[09:26:41] <alex_joni> would have wanted his feedback on classicladder
[09:27:34] <anonimasu> he came in pretty late though
[09:42:29] <alex_joni> seen that
[09:43:49] <anonimasu> :)
[09:43:57] <anonimasu> * anonimasu is drawing nametags right now
[09:44:09] <anonimasu> now I just need a engraving font.
[09:44:43] <alex_joni> * alex_joni is a sucker for Verdana
[09:44:48] <alex_joni> I just love it :D
[09:58:54] <anonimasu> yeah
[09:58:56] <anonimasu> I like verdana too
[09:59:02] <anonimasu> although I dont know how that's for engraving
[09:59:03] <anonimasu> bbl..
[09:59:06] <anonimasu> lunch
[09:59:14] <alex_joni> enjoy
[10:34:01] <A-L-P-H-A> morning
[10:34:24] <alex_joni> morning
[10:34:38] <A-L-P-H-A> so what's new for today?
[10:34:46] <alex_joni> not much ;)
[11:12:15] <A-L-P-H-A> alex_joni, what do you use to program atmels? [or was it you that programs atmels?]
[11:13:29] <alex_joni> I do
[11:13:36] <alex_joni> well I have a JTAG programmer
[11:13:36] <A-L-P-H-A> I just downloaded winavr.
[11:13:44] <alex_joni> and a parallel programmer I built
[11:14:00] <A-L-P-H-A> I have an willem programmer [but not at90s2313 adaptor]
[11:14:16] <A-L-P-H-A> I _had_ a parallel programmer.
[11:14:21] <A-L-P-H-A> I'm going to have to build a new at90s2313 programmer... the old one well... got something spilt on it, and caused it to disintegrated.
[11:15:25] <alex_joni> hehe
[11:15:26] <alex_joni> yeah
[11:15:48] <A-L-P-H-A> I mean what do you use to code with?
[11:16:13] <alex_joni> avrgcc
[11:16:27] <alex_joni> software written in Programmers Notepad
[11:16:32] <alex_joni> and winavr for debugging
[11:16:39] <A-L-P-H-A> so essentially the winavr package.
[11:16:45] <alex_joni> yup
[11:17:05] <A-L-P-H-A> got any code I can look at? [checking avrfreaks.net right now]
[11:17:25] <alex_joni> what would you need?
[11:17:35] <alex_joni> I usually use ethernut as an OS
[11:17:37] <alex_joni> and expand that
[11:17:42] <alex_joni> with what I need
[11:17:45] <alex_joni> www.ethernut.de
[11:17:47] <A-L-P-H-A> I don't know what that is.
[11:18:11] <A-L-P-H-A> that won't fit on an 90s2313.
[11:18:19] <A-L-P-H-A> only chip I got right now, and I have many of them. :(
[11:18:49] <A-L-P-H-A> well. I used to just take the atmel code, and expand that [which I never got very far]
[11:19:23] <A-L-P-H-A> I don't know if I'll be able to find the code I had... it was in asm. The logic was right, but I couldn't get it to start... unless I reset the device, and then it would go.
[11:19:37] <A-L-P-H-A> anyways, what I'm trying to do is...
[11:20:06] <A-L-P-H-A> do that tach thing that communicates to an LED/LCD I bought. [I'll get the specs in a sec]
[11:20:34] <A-L-P-H-A> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3871550696&ssPageName=ADME:B:EOAB:US:6
[11:21:47] <A-L-P-H-A> So, the pins I'll need are. Gnd, VCC (+5V), Crystal (two pines), Reset, Input pulse signal (from tach), output to VT100/hatachi interface [which I don't know how yet]
[11:22:00] <A-L-P-H-A> alex_joni, got eagel layout?
[11:22:40] <alex_joni> not installed
[11:23:23] <A-L-P-H-A> 'ight, nm. I'll just run down the in a pastebin or something.
[11:23:51] <alex_joni> well.. the LCD to interface is not that hard
[11:24:12] <alex_joni> you'll need 8 bits for data
[11:24:28] <alex_joni> enable
[11:24:30] <alex_joni> rd/wr
[11:24:36] <alex_joni> and rs
[11:24:44] <A-L-P-H-A> what's rs?
[11:24:52] <alex_joni> select
[11:25:08] <alex_joni> you can tie that to gnd (I think) and don't output it from the micro
[11:25:19] <alex_joni> rd/wr too, you'll only need wr
[11:25:27] <alex_joni> don't need to read anything from the lcd
[11:25:49] <alex_joni> you could access status from the LCD, but you can do that with delays (easier, and saves you a pin)
[11:26:24] <A-L-P-H-A> the LCD will need 8 pins then?
[11:26:31] <alex_joni> more than 8
[11:26:44] <alex_joni> 8 pins are for data
[11:26:56] <alex_joni> and 1 more for select (enable)
[11:27:52] <alex_joni> I just checked (you need RS too -> Data/Control)
[11:27:54] <A-L-P-H-A> 8 databus. I guess another for the backlight on/off [if I have a spare pin], a read/write pin. What's enabled do?
[11:28:13] <alex_joni> tells lcd you're talking to it
[11:28:22] <A-L-P-H-A> hmm... there's gotta be a way that I can use a TTL to 8bit process.
[11:28:30] <alex_joni> you can use 4 pins only, if you're short on pins
[11:28:32] <A-L-P-H-A> that would save me lots of pins.
[11:28:38] <alex_joni> but you need a serial load register
[11:29:03] <alex_joni> 1 bit where you output the data serially
[11:29:07] <A-L-P-H-A> k, I'll keep that in mind. Or I could just use another atmel to do TTL -> 8pin output.
[11:29:24] <alex_joni> how many pins does your atmel have?
[11:29:26] <A-L-P-H-A> 'ight, those are easy enough to get.
[11:29:27] <A-L-P-H-A> 20 pins.
[11:29:32] <alex_joni> should be enough
[11:29:36] <alex_joni> for all you need
[11:29:45] <A-L-P-H-A> hopefully... but just thinking in advance and escape routes.
[11:31:30] <A-L-P-H-A> I don't need a read/write pin... as I'm always gonna be writing to it.
[11:31:44] <alex_joni> right
[11:31:56] <A-L-P-H-A> Enabled? do I need an enabled?
[11:31:58] <alex_joni> you need enable and rs (to select between data and control)
[11:32:01] <alex_joni> you need
[11:32:09] <A-L-P-H-A> So 10 pins in total?
[11:32:12] <alex_joni> yup
[11:32:21] <alex_joni> or 4 if you want to keep it short
[11:32:41] <A-L-P-H-A> that leaves me with 5 spare pins.
[11:33:01] <alex_joni> yup
[11:33:38] <A-L-P-H-A> I guess TTL output to the computer... that's two pins.
[11:34:10] <A-L-P-H-A> 3 more pins.
[11:34:32] <alex_joni> 1 for the sensor
[11:34:38] <A-L-P-H-A> hahahaha yeah.
[11:34:50] <A-L-P-H-A> 2 pines.
[11:34:51] <A-L-P-H-A> pins.
[11:34:56] <A-L-P-H-A> Mod changes...
[11:35:00] <A-L-P-H-A> mode
[11:35:04] <alex_joni> ok
[11:35:24] <A-L-P-H-A> SFM / TACH / RPM counter --> buttons for up/down
[11:35:39] <A-L-P-H-A> if I need more, I'll use a serial load register chip.
[11:35:46] <alex_joni> yup
[11:35:53] <alex_joni> then you need only 4 pins for LCD
[11:36:38] <A-L-P-H-A> actually, if I use a Serial Load register, then I could use the TTL output that I have assigned out... so I free up 8. Just split the signal from the TTL... wait, can't do that... cause it's awe man.
[11:36:43] <A-L-P-H-A> yeah, 4 pins.
[11:36:50] <A-L-P-H-A> actual no.
[11:37:14] <A-L-P-H-A> yeah, still need the RXD/TXD pins... so I'll need to sets.
[11:37:25] <A-L-P-H-A> that is if I want to keep one set to go out.
[11:37:31] <A-L-P-H-A> go out to the computer.
[11:37:57] <alex_joni> yup
[11:38:20] <A-L-P-H-A> RS232? output for some reason or another... there... there's all 20 pins.
[11:38:39] <A-L-P-H-A> nah, screw rs232... I won't be using a serial port, or shouldn't be.
[11:39:31] <alex_joni> rs232 s usefull for debugging at least
[11:39:35] <alex_joni> scrap it later
[11:39:43] <A-L-P-H-A> 'ight. smart.
[11:40:25] <alex_joni> I wanna have one of these:http://www.digi.com/products/embeddeddeviceservers/digiconnectwime.jsp
[11:41:04] <A-L-P-H-A> won't load
[11:41:14] <alex_joni> try again ;)
[11:42:38] <A-L-P-H-A> http://www.pastebin.com/239583 pin layout.
[11:43:03] <A-L-P-H-A> oh! that looks like fun.
[11:43:18] <A-L-P-H-A> that'd be kick a$$ for remote monitoring.
[11:45:37] <A-L-P-H-A> http://www.pastebin.com/239587 <all pins filled]
[11:46:24] <alex_joni> hmmm
[11:46:40] <alex_joni> I'd connect Data1-Data8to the 8 bits of the LCD
[11:46:59] <alex_joni> that way you can do a simple OUT(Address)=value
[11:47:05] <alex_joni> during programming
[11:47:37] <A-L-P-H-A> those are PB0-PB7.
[11:47:57] <alex_joni> might be
[11:47:59] <A-L-P-H-A> Data1-Data8 are mapped to PB0-PB7. http://www.atmel.com/dyn/resources/prod_documents/doc0839.pdf
[11:49:55] <alex_joni> sounds ok
[11:49:58] <alex_joni> PB0-PB7
[11:54:51] <alex_j> * alex_j testing chatzilla
[11:55:08] <alex_j> seems ok so far ;)
[11:56:38] <A-L-P-H-A> okay. Now what are the proceedures for initiating the atmel? I guess this is where I need to see some code.
[11:56:52] <alex_joni> not really
[11:57:00] <alex_joni> avrlib does the most stuff
[11:57:12] <alex_joni> you need procedures to initialize the LCD
[11:58:40] <alex_joni> some stuff you might find interesting
[11:58:41] <alex_joni> http://lcdproc.sourceforge.net/docs/stable-0-4-x-user-html/c443.html#HD44780-HOWTO
[11:58:53] <A-L-P-H-A> checking
[11:59:12] <A-L-P-H-A> gonna read this. http://www.avrfreaks.net/index.php?module=dpDocs&func=display&mid=82
[12:55:14] <anonimasu> hm I wonder how expensive this emco machine vise is
[12:56:54] <alex_joni> what emco machine?
[12:57:09] <anonimasu> vise..
[12:57:42] <anonimasu> I found one with 110mm clamping area
[12:57:56] <anonimasu> and 110mm jaws..
[12:58:07] <anonimasu> that would be perfect for my mill..
[12:58:12] <anonimasu> I broke my old one :/
[12:58:54] <anonimasu> and I dont want to buy a good vice for 500$
[12:59:02] <anonimasu> or that's not enough
[12:59:05] <anonimasu> more like 600$
[12:59:07] <alex_joni> hmmm
[13:00:12] <anonimasu> argh 325$
[13:00:28] <anonimasu> although that's off the web.. my retailer wont be cheaper then that.
[13:05:23] <anonimasu> I think I should machine one.
[13:05:40] <alex_joni> yup
[13:06:33] <anonimasu> 325 for a small vice is too much.
[13:06:48] <anonimasu> I'd rather spend 600$ and get a precision one.
[13:09:26] <anonimasu> bleh..
[13:09:28] <anonimasu> this is horrid
[13:14:18] <les> hi
[13:14:42] <les> I sometimes use the chinese or taiwanese ones
[13:14:50] <les> most are pretty good
[13:15:09] <anonimasu> hey les
[13:15:14] <anonimasu> :)
[13:15:32] <les> For the surface grinder vice I reground it a little bit to get it perfectly square
[13:15:53] <les> I only took off .02 mm or so
[13:16:31] <les> I have a lab grade surface plate and granite square so I can measure right angles pretty well
[13:16:45] <anonimasu> :)
[13:16:46] <anonimasu> neat
[13:17:23] <les> The Kurt clones about 100x100 mm are $100 or so here
[13:17:29] <alex_joni> morning les
[13:17:37] <les> the angle-lock kind
[13:17:44] <les> morning alex
[13:18:09] <anonimasu> lol 3000sek
[13:18:19] <anonimasu> 441$
[13:18:44] <les> Some of my diamond tool grinding stuff should come today
[13:19:01] <les> The spin index fixture was $37
[13:19:12] <les> I have bought them before
[13:19:19] <les> amazingly good
[13:20:12] <les> The diamond cup 75 mm whell was $100 though
[13:20:19] <anonimasu> I wonder if there's any mono
[13:20:26] <anonimasu> err any engraving fonts on the web for free ;)
[13:20:41] <anonimasu> I am beging cheap today :D
[13:20:43] <anonimasu> being.
[13:20:46] <anonimasu> and I cant type either
[13:20:52] <les> I have really never tried to sharpen spiral carbide router bits
[13:20:52] <alex_joni> free is good
[13:21:12] <les> I just use TTF
[13:21:23] <anonimasu> hm, I dont know how to use thoose nicely..
[13:21:41] <les> but I think there are plenty of single line fonts out there
[13:22:08] <anonimasu> I dont know how visualmill handle thoose though
[13:22:25] <les> Can you do g-code from .dxf?
[13:22:44] <anonimasu> yeah
[13:22:45] <alex_joni> there's ace who does that
[13:23:01] <anonimasu> hm, I can export dxf off solidworks..
[13:23:20] <les> If so, I think I saw some shareware TTF to dxf
[13:24:03] <anonimasu> nice
[13:24:14] <les> must run out ...back in a while
[13:24:22] <alex_joni> http://home.carolina.rr.com/gcodemcode/ttftodxf.htm
[13:25:03] <alex_joni> http://home.carolina.rr.com/gcodemcode/
[13:28:00] <A-L-P-H-A> there's also outlineart
[13:28:11] <A-L-P-H-A> which does a nice job.
[13:30:47] <anonimasu> nice :)
[13:39:42] <A-L-P-H-A> hmm... things to make... atmel test board... [reset, crystal, power, ground, eight outputs, misc inputs, ttl] ... ttl <-> rs232 board... fun fun. Wished I bought an rs233 board [no caps then]
[13:41:47] <rayh> I found some stuff using an atmel. Ethernut I think.
[13:42:16] <anonimasu> oh, are you coding atmels
[13:42:17] <anonimasu> neat
[13:42:26] <A-L-P-H-A> trying to code.
[13:42:36] <anonimasu> if you need any help ask me :)
[13:43:31] <A-L-P-H-A> yes! I do need help. I'd like to learn AVRc or AVRgcc... and how to initialize things, and how to do interrupts from within C. I've got some code in asm, which I understand... but I don't know how to integrate that information I do have to an LCD I just recently purchased.
[13:43:55] <anonimasu> :)
[13:44:05] <anonimasu> using interupts isnt that hard
[13:44:26] <A-L-P-H-A> in asm, it's not hard... just that I don't have very much code I can look/learn from.
[13:44:33] <anonimasu> there's a good example in the avrgcc manual
[13:44:36] <A-L-P-H-A> much C code... I have enough asm code to learn from.
[13:44:48] <anonimasu> seen? www.avrfreaks.net
[13:45:01] <anonimasu> it has loads of info
[13:46:19] <anonimasu> is the UNITS = 0.03937007874016 in mm?
[13:46:21] <anonimasu> or in inch?
[13:46:27] <anonimasu> in the emc config?
[13:46:43] <A-L-P-H-A> I'll recheck it again for C code... I've found an article I understood... http://www.avrfreaks.net/index.php?module=dpDocs&func=display&mid=71
[13:46:57] <anonimasu> oh, articles..
[13:46:58] <anonimasu> heh
[13:47:01] <anonimasu> look in the forum
[13:47:05] <anonimasu> if you want good examples
[13:47:14] <rayh> The native units are 1 = 1mm
[13:47:26] <anonimasu> nice
[13:47:32] <anonimasu> then my values will plug right in..
[13:47:35] <anonimasu> off the turbocnc setup..
[13:47:43] <rayh> By multiplying 1 by .039... you get inch units.
[13:47:49] <anonimasu> with backslash and all checked..
[13:47:56] <anonimasu> * anonimasu is in a metric country
[13:48:13] <anonimasu> http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewforum&f=2&sid=5747d88d79524588d6198404502817b7
[13:48:14] <alex_joni> alpha: there is max233 (if I remember it right)
[13:48:21] <anonimasu> a-l-p-h-a: look from there..
[13:48:22] <alex_joni> it's an max232 with internal caps
[13:48:34] <alex_joni> rayh: hello
[13:48:39] <anonimasu> remind me to never buy max232 ;)
[13:48:40] <A-L-P-H-A> I think it's the other way around.
[13:48:43] <anonimasu> but 233 instead..
[13:48:53] <rayh> Hey Alex.
[13:48:53] <A-L-P-H-A> max233 has the internal caps. 232 needs external caps.
[13:48:59] <anonimasu> 232 dosent have caps..
[13:49:03] <anonimasu> :D
[13:49:05] <A-L-P-H-A> either way I have lots of caps.
[13:49:10] <anonimasu> hm, I might have my mill running tonight
[13:49:16] <anonimasu> or I will have my mill running
[13:49:19] <A-L-P-H-A> I hae everything I actually need... just need to put them together.
[13:51:37] <A-L-P-H-A> hmm... if I have 1 coming out of portB, could I have drive both an LCD databit, and a LED at the same time? like just split it like a "Y", or do I need a 5VDC 10K pullup resistor you think?
[13:51:46] <A-L-P-H-A> or 4.7 whichever.
[13:53:34] <anonimasu> I'll be back in a bit.
[13:53:45] <anonimasu> I probably will have more questions about the setup of emc ;)
[13:54:14] <alex_joni> alpha: that's what I said (233 has internal caps)
[14:00:59] <alex_joni> rayh: how's it going?
[14:01:52] <rayh> Good. The lake is beautiful this morning. Last night several fisherman had their pickups out there.
[14:01:59] <alex_joni> cool
[14:02:08] <alex_joni> how big is the lake?
[14:02:15] <alex_joni> and don't tell me in gallons ;)
[14:02:57] <rayh> 2k long <k wide
[14:03:06] <alex_joni> cool
[14:03:07] <rayh> We live on the south end.
[14:03:12] <alex_joni> nice to boat on
[14:03:27] <rayh> www.up.net/~rehenry
[14:04:06] <alex_joni> aren't you concearned about spammers?
[14:05:07] <rayh> I get so much spam anyway
[14:05:20] <rayh> That is not a current site.
[14:05:31] <alex_joni> I see
[14:05:34] <rayh> but some of the images are nice.
[14:06:07] <alex_joni> * alex_joni is looking
[14:06:11] <alex_joni> actually...
[14:06:16] <alex_joni> * alex_joni is enjoying ;)
[14:06:47] <rayh> Lady luck was smiling on us when we got this place.
[14:06:49] <alex_joni> who speaks so well german up there?
[14:07:13] <rayh> Das kann it nicht tun.
[14:07:21] <alex_joni> close
[14:07:22] <alex_joni> ;)
[14:07:34] <rayh> No cigar?
[14:07:51] <rayh> My oldest son lives near Frankfurt.
[14:07:57] <alex_joni> cool
[14:08:20] <rayh> Much of the translation is babelfish and there are some strange things.
[14:08:38] <alex_joni> like?
[14:09:08] <rayh> My brother in law in Dortmund is a ham radio operator. Shenken radio apparat.
[14:14:50] <alex_joni> coo
[14:15:04] <rayh> There is a sled run down to the lake. You can see the start of it between trees at http://freedom.up.net/~rehenry/seasons/winter1.jpg
[14:16:00] <rayh> I set up a pair of photocells at the bottom and two of my boys could get to about 60 MPH there.
[14:17:17] <rayh> They were using rubber tire tubes.
[14:17:22] <alex_joni> coo
[14:17:25] <alex_joni> that's a lot
[14:17:29] <alex_joni> are you in any pic?
[14:17:55] <rayh> Seems like around the campfire. Let me look
[14:24:01] <rayh> http://freedom.up.net/~rehenry/recent4/dad1.jpg Is as good as it gets here.
[14:25:32] <rayh> There are quite a few of the guys shown at http://www.pmdx.com/NAMES2002/index.html
[14:28:03] <alex_joni> cool ;)
[14:28:44] <alex_joni> nice hat paul_c wears
[14:28:52] <rayh> You're being generous. We are a odd bunch.
[14:29:04] <alex_joni> odd is good ;)
[14:29:20] <rayh> How true that is.
[14:29:48] <alex_joni> it's nice to have so different personalities, -> many productive ideeas
[14:30:02] <rayh> exactly
[14:31:55] <alex_joni> I wonder if I fit in ;)
[14:32:27] <rayh> We came to that conclusion (yes!) quite a while ago.
[14:32:39] <alex_joni> what's "we" ?
[14:33:07] <rayh> The folk you know from this list and the emc.
[14:33:22] <alex_joni> oh cool ;)
[14:34:13] <rayh> The internet is fantastic. I've got folk that I consider my friends all over the world.
[14:38:54] <alex_joni> nice
[14:39:05] <alex_joni> it's really helpfull...
[14:39:17] <rayh> Yes it is.
[14:39:44] <alex_joni> but it's beeing exploited a lot
[14:39:47] <alex_joni> spam & all that
[14:40:35] <rayh> True. And there is so much information that it is sometimes difficult to find what you need.
[14:41:02] <alex_joni> yup :)
[14:41:09] <alex_joni> but.. that's common ;)
[14:41:22] <alex_joni> I sometimes use google because I find information faster than searching my machine
[14:41:35] <rayh> * rayh has Linux showing on a small TV. Truely an ugly picture.
[14:41:40] <alex_joni> I know I have a datasheet somewhere, but I find it faster on the net
[14:41:42] <alex_joni> lol
[14:41:46] <alex_joni> what resolution?
[14:41:51] <rayh> I use google.com.linux a lot.
[14:42:04] <rayh> 640x480
[14:42:23] <rayh> oops google.com/linux
[14:42:52] <alex_joni> hmmm.. never used it
[14:42:59] <alex_joni> I used to use groups.google.com a lot
[14:43:14] <alex_joni> I even had a newsgroups provider a while ago...
[14:43:19] <alex_joni> but it seems to disappear
[14:43:21] <alex_joni> slowly
[14:45:00] <rayh> There is a lot of pressure on commercial ventures like these.
[14:51:31] <alex_joni> * alex_joni goes to play with an LCD
[14:51:59] <rayh> Catch you later. Have a good day.
[14:52:31] <alex_joni> bye
[15:05:18] <anonimasu> hm..
[15:05:27] <anonimasu> can anyone help me a bit?
[15:05:41] <anonimasu> I get "joint" following error when I make any moves with my y axis

[16:41:45] <A-L-P-H-A> EVIL!
[16:42:18] <A-L-P-H-A> my supplier just quoted me some insane price on a drill chuck. Drill chuck is MSRP is $189USD. They want to sell it to me for $343.82CDN + 15% tax!
[16:42:32] <A-L-P-H-A> 'screw' 'that'.
[16:42:51] <A-L-P-H-A> over $100 bucks difference... prior tax.
[16:43:04] <A-L-P-H-A> even if I slap $15 for shipping from mcmaster.com

[17:24:06] <anonimasu> hwllo alex
[17:24:23] <alex_joni> hey
[17:24:34] <anonimasu> do you have any idea about setting up emc?
[17:24:45] <anonimasu> I get joint somthing error
[17:24:48] <anonimasu> on my y axis
[17:25:03] <anonimasu> joint following error.. I think it is
[17:25:04] <alex_joni> can you be more specific?
[17:25:14] <alex_joni> that's if it can't follow the speed you set
[17:25:29] <anonimasu> I am running at the standard speed..
[17:25:55] <anonimasu> and the x axis works..
[17:26:49] <anonimasu> and I copied the settings since the ballscrew/reduction's are the same
[17:28:07] <anonimasu> maybe I touched somthing I shouldnt..
[17:30:39] <anonimasu> I'll grab a fresh ini and start over and see if it works then
[17:30:53] <anonimasu> btw I ordered a vise :)
[17:30:57] <alex_joni> better ;)

[17:38:33] <anonimasu> I need to burn a cd anyway...
[17:39:58] <A-L-P-H-A> I've got it... chuck - arbour - shaft collar - bearing - bearing - shaftcollar ---- spacer ---- shaft collar - bearing - pulley. Wonder how unbalanced that would be at 15K rpm? hmm...
[17:40:50] <anonimasu> hm, build a balancing machine?
[17:40:52] <anonimasu> ^_^
[17:40:56] <anonimasu> I got a good page on one

[18:19:30] <anonimasu> it's at the other laptop
[18:19:35] <anonimasu> at work
[18:19:57] <A-L-P-H-A> anonimasu, oh... cool, so it's not lost I hope... if you can pass me it next time, that'd be awesome.
[18:21:07] <A-L-P-H-A> http://ronkilber.tripod.com/balancer/balancer.htm ??
[18:21:33] <A-L-P-H-A> I don't see how that's gonna help me at 15K+ rpm.
[18:21:50] <anonimasu> no
[18:21:57] <anonimasu> I'll look it up :)
[18:22:23] <anonimasu> googling for it now
[18:22:23] <alex> damn suspend
[18:29:58] <anonimasu> http://www.technologie-entwicklung.de/
[18:29:59] <anonimasu> there
[18:31:26] <anonimasu> a-l-p-h-a: :)
[18:31:52] <anonimasu> a-l-p-h-a: http://www.technologie-entwicklung.de/Gasturbines/Balancing_Tool/balancing_tool.html
[18:32:02] <A-L-P-H-A> reading it now. :)
[18:32:30] <anonimasu> I am jealous of that guy
[18:32:37] <anonimasu> in the same way I am jealous of les router ;)
[18:32:37] <anonimasu> :D
[18:34:45] <anonimasu> what do you think about that balancer?
[18:39:06] <A-L-P-H-A> anonimasu, I see how it's testing if the part is balanced, how do you know where to drill take out to balance it?
[18:39:39] <A-L-P-H-A> the pizoelectic sensor only tells you that there is imbalance... not where.
[18:39:42] <anonimasu> you have a led/stroboscope..
[18:40:52] <anonimasu> did you see http://www.technologie-entwicklung.de/Gasturbines/Balancing_Tool/Available_Parts/available_parts.html
[18:40:55] <anonimasu> also`
[18:40:55] <A-L-P-H-A> I guess I don't know how it works.
[18:40:58] <anonimasu> ?
[18:41:09] <anonimasu> he trigger level will then be set to a value that only the most positive part of the imbalance waveform will exceed the trigger level. If the LED is pointed to the wheel to be balanced, this seems to be standing still (stroboscopic effect). If there has been a mark placed on it before (or has already been present), you can stop the wheel and place it statically in the position that has been spotted with the LED.
[18:41:55] <anonimasu> Now a counterweight will be attached to the other side of the wheel (usually I use textile adhesive tape) and the balance re-checked. During this process the trigger level will have to be set lower each time, as the imbalance decreases. When the vibration caused by imbalance approaches the noise level generated by the bearings, it becomes difficult to find a trigger level setting that will give a "standing" wheel display, then I usually stop and grind some mate
[18:42:02] <anonimasu> :)
[18:42:37] <anonimasu> brb kiosk
[18:49:00] <A-L-P-H-A> so essentially, I gotta do this in a dark room, so the strobe effect will work. And as long as there is a distiguishing mark I can measure. Now, the question is now, which side of the mark is imbalanced? the mark side,or the opposide side of the mark? :)
[18:49:33] <A-L-P-H-A> n this position the "heavy side" of the wheel will point directly to the transducer that causes the LED to light when pushed on (the "+" transducer).
[18:49:35] <A-L-P-H-A> got it. :)
[19:02:39] <anonimasu> the opposide one
[19:02:42] <anonimasu> opposite one..
[19:02:43] <anonimasu> :)
[19:03:32] <A-L-P-H-A> no, the transducer side. :P :)
[19:04:05] <anonimasu> if you trigger a real strobelight you wont have to worry ;)
[19:07:02] <anonimasu> or a high power led..
[19:07:02] <anonimasu> YES the one which isnt lit..
[19:07:02] <anonimasu> :)
[19:07:02] <anonimasu> opposite of the strobe ;)
[19:07:03] <anonimasu> that guy has a violent vaccum pump
[19:07:05] <anonimasu> http://www.technologie-entwicklung.de/Gasturbines/Vacuum_Pump/vacuum_pump.html
[19:08:16] <A-L-P-H-A> http://www.technologie-entwicklung.de/Gasturbines/mu-Turbine__KP31_/mu-turbine__kp31_.html this is so freak'n cool.
[19:09:10] <anonimasu> I'll machine one someday
[19:09:15] <anonimasu> when I get a cnc lathe.
[19:09:20] <anonimasu> get/build
[19:09:48] <anonimasu> I just need a base in somthing like epucrete ;)
[19:11:17] <anonimasu> small but super rigid ;)
[19:12:24] <anonimasu> I dont think the machining involved are that horrid..
[19:14:42] <A-L-P-H-A> the veins are.
[19:16:04] <anonimasu> some cam program magic..
[19:16:05] <anonimasu> :)
[19:17:28] <anonimasu> I think the NGV would be the hardest part to make
[19:17:56] <anonimasu> umm not ngv..
[19:18:15] <anonimasu> the fuel part..
[19:18:19] <anonimasu> with the tubes..
[19:18:35] <anonimasu> you probably would have to buy a ngv..
[19:21:28] <A-L-P-H-A> very very neat site.
[19:22:27] <anonimasu> http://www.hopersoft.com.tw/
[19:22:30] <anonimasu> more turbines ;)
[19:29:53] <anonimasu> I love the twinspool design
[19:29:54] <A-L-P-H-A> the .tw guys balancer is easier.
[19:30:26] <anonimasu> hehe
[19:31:29] <anonimasu> yep
[19:33:41] <A-L-P-H-A> then again, it's doing the same thing... except one's doing it via a circuit, the other is having a computer doing the calculation of a given phase to generate the pulse. The circuit one just does away with the computer... [not expensive either]
[19:33:53] <anonimasu> yeah
[19:34:01] <anonimasu> yep
[19:34:27] <A-L-P-H-A> could replace the peizo electric sensor with a accelerameter. Same result.
[19:34:34] <anonimasu> * anonimasu nods
[19:35:47] <anonimasu> did you see the monocopter page?
[19:41:35] <A-L-P-H-A> that thing scared me.
[19:41:41] <A-L-P-H-A> you're supposed to be strapped to that???
[19:42:21] <anonimasu> yeah..
[19:42:22] <anonimasu> :D
[19:42:32] <anonimasu> but the skill require to build that thing
[19:48:56] <anonimasu> :i'll be back in a little bit going to retry setting up emc
[19:49:23] <A-L-P-H-A> gl
[19:51:43] <anonimasu> thanks
[19:51:47] <anonimasu> I'll need it
[19:56:07] <A-L-P-H-A> any respectable CAD app out there for linux?
[20:02:07] <asdfqwega> A-L-P-H-A: A question often asked. http://pfrostie.freeservers.com/cad-tastrafy/
[20:02:57] <asdfqwega> I have a question about LinuxCAD - Has anybody here used it?
[20:03:20] <asdfqwega> I've seen the link on the LinuxCNC.org page
[20:03:54] <asdfqwega> I bought a copy back in '99, I think
[20:04:20] <A-L-P-H-A> I've heard of it... never touched it.
[20:04:47] <asdfqwega> And I chalked off the $100 I paid as "learning experience"
[20:05:26] <asdfqwega> It was completely non-functional, to put it politely
[20:05:58] <anonimasu> heh
[20:06:10] <anonimasu> I just wasted a cd.
[20:06:15] <pemmet> hi there...
[20:06:35] <pemmet> does anyone know anything about a company: Daedal inc?
[20:06:42] <anonimasu> the prog truncuated my filenames
[20:07:14] <pemmet> * pemmet is that student at WPI doing his Senior Project on Linux CNC
[20:07:59] <A-L-P-H-A> anonimasu, wasn't it only 2d?
[20:09:07] <anonimasu> a-l-p-h-a: what?
[20:09:13] <A-L-P-H-A> I would like a cad program for linux that has nice 3d modelling, with osnaps, and a CLI similar to autocad... or the ability to alias autocad command names to represent the ones in that program.
[20:09:14] <anonimasu> :D
[20:09:24] <A-L-P-H-A> linuxCAD
[20:09:28] <anonimasu> I havent used anything like that..
[20:09:32] <anonimasu> I use solidworks..
[20:09:33] <anonimasu> :)
[20:09:38] <anonimasu> on win for drawing.
[20:15:18] <anonimasu> I hate autocad/similiar stuff.. they are heavy to work with
[20:15:18] <anonimasu> :)
[20:15:18] <A-L-P-H-A> sorry, having two conversions at once... a friend is taking the leap...but the only thing stopping me from leaping over to linux is a good chat client (gaim isnot good), and a powerful enough CAD package.
[22:00:51] <robin_sz> meep!
[22:02:09] <robin_sz> today was a good day
[22:04:29] <robin_sz> with some slightly odd bits thrown in
[22:04:43] <anonimasu> I found the error.
[22:04:45] <anonimasu> :)
[22:04:46] <anonimasu> I think
[22:04:51] <robin_sz> error?
[22:04:55] <anonimasu> turbocnc probably stores it's values in " in the config.
[22:05:03] <anonimasu> I grabbed the values I've been running off there..
[22:06:00] <anonimasu> in this case 0.000065748031 per step
[22:06:11] <robin_sz> sigh
[22:06:17] <robin_sz> why do people do that?
[22:06:49] <anonimasu> do what?
[22:06:50] <anonimasu> being stupid?
[22:06:51] <anonimasu> ^_^
[22:07:03] <robin_sz> doesn't 82345.2 stepps per inch work out easier than 0.000000034345503 inches per step in the head?
[22:07:25] <robin_sz> anyway ....
[22:07:27] <anonimasu> oh, I had it pre calculated..
[22:07:29] <anonimasu> :)
[22:07:46] <robin_sz> yeah, but it just seems unwieldly
[22:07:48] <anonimasu> that's the problem with my "joint 1 following error" message..
[22:07:59] <anonimasu> that's true
[22:08:05] <robin_sz> anyway .. my local farmer visited me today
[22:08:15] <anonimasu> I'll calc it tomorrow..
[22:08:22] <anonimasu> got some fibreglass all over the floor..
[22:08:32] <anonimasu> or rather a fibreglass part.. dont want to breathe in more fumes
[22:08:49] <robin_sz> I rent some land to him, for grass production for silage
[22:09:04] <robin_sz> hes asked if he can replant it ...
[22:09:08] <anonimasu> I am trying to make a mold off a plastic cover.. but I think I'll just mill the molds directly
[22:09:09] <robin_sz> with LUPINS!!
[22:09:16] <anonimasu> lol
[22:09:17] <robin_sz> lupins i ask you
[22:09:26] <robin_sz> for cattle fodder
[22:09:40] <robin_sz> sorry, back to fibreglass
[22:10:07] <anonimasu> robin_sz: do you do fibreglass?
[22:10:16] <robin_sz> not if I can help it
[22:10:25] <robin_sz> I have done in the past though
[22:10:28] <anonimasu> hehe ok..
[22:10:32] <anonimasu> it's a hell..
[22:10:35] <robin_sz> yep
[22:10:48] <anonimasu> prepreg cf is nicer..
[22:10:52] <robin_sz> yep
[22:11:07] <robin_sz> and not as expensive as you might think either
[22:11:19] <anonimasu> it's expensive over here
[22:11:27] <anonimasu> or well hard to get..
[22:11:28] <robin_sz> I did some m'cycle mudguards in cf
[22:11:44] <robin_sz> worked out <5 GBP per gaurd in materials
[22:12:04] <anonimasu> nice
[22:12:21] <anonimasu> I dont really need cf though..
[22:12:22] <anonimasu> it just weighs more..
[22:12:29] <robin_sz> but you use less
[22:12:30] <anonimasu> since I dont have a autoclave and vaccum..
[22:12:35] <robin_sz> shrug
[22:12:38] <robin_sz> anyway ...
[22:12:59] <robin_sz> we're going to be knee-deep in LUPINS!!
[22:13:32] <anonimasu> lol
[22:13:46] <robin_sz> got the g2002 firmware to build now
[22:15:00] <robin_sz> what *exactly* does the 'extern' pragma do in C?
[22:16:43] <robin_sz> I *thought* it was used when there was going to be some external definition used that would only be visible at link time
[22:17:16] <robin_sz> so you can do extern static void fooBar(void);
[22:17:43] <robin_sz> and just make damn sure you have a fooBar(void) available at linktime
[22:18:05] <robin_sz> except here its being useed in the same file as the function definition ...
[22:21:30] <asdfqwega> Yay!
[22:21:57] <asdfqwega> Figuring out differences from emc1 to paul's emc1/libnml
[22:22:02] <rayh> robin_sz: When you get time, talk to me about 2002 and EMC. I got a request for info today.
[22:22:52] <asdfqwega> I've not got home switches, and a quick test showed that the M62/M63 usage had changed, too
[22:23:22] <asdfqwega> oops, s/not got/now got
[22:25:53] <anonimasu> :)
[22:27:21] <anonimasu> * anonimasu yawns
[22:29:15] <anonimasu> hm, I guess I just have to calculate this into steps per inch ;)
[22:29:20] <anonimasu> then I'll be up and running tomorrow..
[22:32:58] <anonimasu> my vise probably arrives at friday morning
[22:34:28] <anonimasu> I wonder if I should start to sell cheap blowoff valves for car's..
[22:34:33] <anonimasu> machine/sell..
[23:31:45] <anonimasu> goodnight everyone
[23:58:48] <robin_sz> ray
[23:58:53] <robin_sz> there went ray
[23:59:15] <robin_sz> we should feel very guilty
[23:59:46] <robin_sz> the madness of the SILLY_FUNCTION_NAMES() is affecting other projects
