[00:00:24] <dpy> holland only has 16 million civilians
[00:00:33] <dpy> london alone has that many
[00:00:33] <robin_sz> but we are a poor country, with mass unemployment
[00:00:35] <dpy> I believe
[00:00:45] <robin_sz> london has 5 million
[00:01:01] <dpy> if it were up to al-qaeda it would have been a little less by now
[00:01:07] <robin_sz> yeah
[00:01:07] <dpy> oh ok
[00:01:12] <robin_sz> but we are solving that
[00:01:19] <robin_sz> one by one ...
[00:01:33] <dpy> and you should
[00:01:37] <robin_sz> for some reason, we started with brazillian electricians
[00:01:43] <dpy> lol
[00:01:46] <robin_sz> quitre why, no one os sure
[00:02:47] <dpy> rswww looks ok
[00:02:53] <dpy> I think I'll stick with that
[00:03:09] <robin_sz> there will bi plastics suppliers in .nl
[00:03:17] <robin_sz> cheaper than rswww
[00:03:24] <robin_sz> but rs are convenient
[00:03:50] <dpy> wait a minute
[00:03:54] <dpy> they have a DUTCH site
[00:03:58] <robin_sz> * robin_sz waits
[00:04:40] <robin_sz> they probably have only a reduced stock list
[00:04:50] <dpy> http://www.rs-components.nl
[00:04:51] <robin_sz> liek spare parts for edam cheese making machines
[00:05:21] <robin_sz> and tulip bulb packing systems
[00:05:41] <robin_sz> * robin_sz wonders what else holland is famous for
[00:06:20] <dpy> I don't know and I don't care
[00:06:33] <robin_sz> mmm ....
[00:06:37] <robin_sz> Bicycles!
[00:06:37] <dpy> I'm not particularly proud of living here
[00:06:47] <robin_sz> dykes ...
[00:07:08] <robin_sz> windmills and clogs :)
[00:07:18] <dpy> lack of space
[00:07:34] <robin_sz> well ... drain some more sea!
[00:07:42] <robin_sz> or are you flooding bits again?
[00:09:37] <dpy> what a rip off
[00:09:46] <dpy> dutch site is more expensive
[00:09:50] <dpy> +5 EUR
[00:10:09] <robin_sz> thats euros for you ...
[00:10:15] <robin_sz> not worht much
[00:11:35] <dpy> but as my great aunt used to say: better expensive than not available
[00:11:54] <robin_sz> does tha apply to girls too?
[00:13:22] <robin_sz> maybe I buy delrin and send it to you ... you send back buggy wheels?
[00:26:19] <dpy> lol
[00:30:36] <Jymmm> is it hollnad or amsterdam that has the legal drugs and red light district
[00:31:35] <Jacky^> girls ? where ? O_O
[00:31:59] <Jymmm> Jacky^ in your bedroom closet.... 5 of them
[00:32:06] <Jacky^> lol
[00:32:08] <Jacky^> :)
[00:32:21] <Jacky^> i can't see them :\
[00:32:29] <Jacky^> bah..
[00:33:03] <Jymmm> your not to SEE them, you FEEL them
[00:33:32] <Jacky^> +_+
[00:33:44] <les> I wouldn't mind one for a little while either
[00:33:50] <Jymmm> Jacky^ when you FEEL the one with squishy knees..... that's NOT her knees!!!
[00:34:41] <les> One of my semi-retired employees is 76 years old. He brought home a twenty something from the hillbilly bar a while ago.
[00:34:53] <les> rough looking though.
[00:34:59] <Jacky^> :-)
[00:35:10] <Jymmm> roughly looking twrnty something..... yeow
[00:35:24] <Jymmm> but at 76, who cares! lol
[00:35:32] <les> I guess
[00:35:55] <les> Way too far out in the woods here.
[00:36:05] <Jymmm> les : Come on now, haven't you figured out WHY they ask "Paper or Plastic" at the stores yet?
[00:36:23] <les> ??
[00:36:42] <Jymmm> roughly looking 20yo.... Paper bag or her face or plastic.
[00:36:51] <les> oh. haha
[00:37:20] <Jymmm> and notice that is mostly plastic! LOL
[00:37:57] <Jymmm> les I took your recomendation and ok'ed the rails.
[00:38:14] <les> good plan
[00:38:45] <les> BIG performance gain per dollar I think
[00:38:55] <Jymmm> I also told them I haven't seen the machine working yet, and I want to see everything going first, so I'll either send them the $285 or the machien back.
[00:39:08] <les> heh
[00:39:11] <Jymmm> Not exactly in those words though.
[00:39:53] <Jymmm> It ALMOST feels like 'bait and switch'
[00:40:18] <les> yeah
[00:40:31] <les> well I hope it works well
[00:40:43] <Jymmm> I'm paying for their QA screwups, as they're loosing money. but I feel the machien can be worthwhile, just have little confidence in their QA area.
[00:41:05] <Jymmm> It's all silly little dumb mistakes.
[00:41:13] <Jymmm> Me too, thanks.
[00:41:18] <les> I have some reservations about the design but I hope it will do ok for signs
[00:41:58] <les> I would have used tandem screws
[00:42:19] <Jymmm> les : Well, if it at least gets me off the ground 'fairly well' I'm ok with it. It's mostly to work up being able to buy a laser when I can.
[00:43:18] <Jymmm> les : Rough guestimate... what would servo SYSTEM run me?
[00:44:11] <les> Well it's a bit. I have been trying to change that.
[00:44:18] <Jymmm> motors/encoders/drivers/breakout/PS
[00:44:39] <fenn> whaddya mean "i have been trying to change that"?
[00:44:42] <les> 3 motors, three amps, card, breakout
[00:45:07] <les> about $1200
[00:45:20] <Jymmm> what size servos (torque wise) ?
[00:45:52] <les> 2-300 in oz cont for the biggest
[00:46:00] <les> x
[00:46:25] <Jymmm> btw... Motor Calculator --> http://www.shinano.com/xampp/skvconv.swf
[00:46:31] <les> y and z can be smaller than x
[00:46:56] <les> I use motioneering design suite
[00:47:49] <les> oh posted to cad_cam about arc blending
[00:47:59] <les> hope not to start a scrap
[00:48:18] <les> but we can't have wrong information
[00:49:08] <fenn> how do you manage to read cad cam every day?
[00:49:49] <fenn> i mean, there's like 100 messages a day
[00:49:53] <Jymmm> fenn : digest mode
[00:49:55] <les> I just scan it quickly
[00:50:14] <les> I read one out of twenty perhaps
[00:50:19] <Jymmm> with finger on the DELETE key =)
[00:50:44] <fenn> i wonder if someone has an archive of all the messages in text format
[00:50:52] <SWPadnos> PGOffline
[00:51:01] <les> I will admit to using it for advertising
[00:51:08] <SWPadnos> you can download the whole shebang and browse / search offline
[00:51:27] <les> I only post for helpful information to help hobbyists
[00:51:28] <Jymmm> les nothign wrong with that
[00:51:29] <fenn> and it works for yahoo groups?
[00:51:46] <SWPadnos> I think it was made for Yahoo groups (could be wrong)
[00:51:50] <fenn> yahoo decided to block my IP when i tried to wget -rk
[00:52:03] <les> but in posting I shoot out several thousand links to my web page
[00:52:09] <SWPadnos> http://www.pgoffline.com/index.htm
[00:52:29] <Jymmm> les : Well ON-TOPIC commercial post are allowed.
[00:52:45] <Jacky^> umpf :(
[00:53:14] <les> when I post the hits on the engineering part of my web site go through the roof
[00:53:28] <fenn> heh i like the list of groups he has on the tutorial
[00:53:34] <les> but I never post ads...just answers to questions
[00:53:36] <Jymmm> les lol, get some google ads goin up there =)
[00:53:45] <SWPadnos> yeah - CAD_CAM_EMC ...
[00:54:25] <les> oh SWP...I was looking at that tc.c code
[00:54:30] <SWPadnos> ya
[00:54:35] <les> about the circular moves...
[00:54:45] <SWPadnos> ya
[00:54:59] <Jacky^> it is nice to be with you but the bed calls to me :(
[00:55:02] <Jacky^> night
[00:55:05] <SWPadnos> see ya
[00:55:09] <les> it is operating on .x .y .z structure elements
[00:55:21] <les> not .a .b .c
[00:55:37] <SWPadnos> OK - so the comment may have had bad terminology :)
[00:55:58] <les> I did not mention it in the cad cam post
[00:55:58] <fenn> cool he's got the groups already archived
[00:56:11] <fenn> you can download them without having to use pgoffline
[00:56:11] <les> but I think that is it
[00:57:23] <les> have a look at the if statement:

[00:57:45] <les> oops
[00:57:48] <SWPadnos> that doesn't look like an if statement
[00:57:49] <les> sorry
[00:58:10] <les> one more time
[00:58:18] <les> /* If either this move or the last move was a pure rotation
[00:58:18] <les> reset the velocity and acceleration and block any blending */

[00:58:39] <les> unitCart = tcGetUnitCart(thisTc);
[00:58:41] <les>
[00:58:57] <SWPadnos> I don't think that's it.
[00:59:11] <les> how come?
[00:59:22] <SWPadnos> it just does what the comment says - if this or the previous move was pure rotation, then set all velocities to 0
[00:59:31] <SWPadnos> that would include a,b,c,x,y,z
[00:59:41] <SWPadnos> (though they're not doing a,b,c)
[00:59:42] <fenn> rotation means roll, pitch, yaw, right?
[00:59:53] <les> should
[00:59:55] <SWPadnos> that's what I would think - a,b,c in G-code parlance
[01:00:19] <SWPadnos> but a circular move isn't rotation, it's translation on two axes
[01:00:30] <les> well I did not reference it in the post
[01:00:37] <SWPadnos> no - I noticed that
[01:00:42] <les> because I was not sure
[01:01:16] <les> But I know there is no blending....I spent many days work on that
[01:02:04] <les> it caused me great problems
[01:03:02] <SWPadnos> I wonder if Jon has some older version of the interpreter / TP that dows it right
[01:03:05] <SWPadnos> does
[01:03:21] <les> I don't want to be confrontational....I should have said "if someone has a version or way that blends arcs I am all eyes!"
[01:03:33] <SWPadnos> yeah - shame on you! :)
[01:04:24] <les> Still, misinformation needs to be corrected.
[01:04:49] <SWPadnos> yep - if only we knew if it *was* misinformation ;)
[01:05:33] <les> I do...with the versions Fred, Paul, and I have run here. But that is not all inclusive
[01:06:05] <SWPadnos> yeah - I seem to recall some discussion of other things that "used to work", but don't now
[01:06:12] <SWPadnos> like tool offsets or something
[01:06:27] <les> yeah
[01:32:19] <Jymmm> les : Fuck it, I can be the scapegoat.... what you want me to say?
[01:36:16] <les> sorry back
[01:43:48] <Jymmm> les Just tell me what to say, and I'll post to CCED on your behalf =)
[01:45:59] <SWPadnos> hey Jymmm, what voltage did you want from your transformer?
[01:47:01] <Jymmm> SWPadnos : Not EXACTLY sure... To drive 3 (maybe 4) of these using geckos http://www.xylotex.com/StepperMotor.htm
[01:47:28] <SWPadnos> right - how about roughly 48VDC, 500VA?
[01:47:45] <SWPadnos> (34VAC, gets 48VDC no load)
[01:47:57] <Jymmm> the 500VA sounds fine, but only 48 DC ?
[01:48:08] <Jymmm> SWPadnos you find something good?
[01:48:29] <SWPadnos> looking on eBay for a small control transformer with fuse block
[01:48:46] <SWPadnos> found this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7532930073
[01:49:25] <SWPadnos> 48V would be a 16x overvoltage - not quite high enough for mega-speeds, but might be good enough
[01:52:05] <Jymmm> SWPadnos : I appreciate it... I'm REAL reluctant from buying conponents that I can't easily replace down the road. I'd hate to be in the middle of a job it breaks and I can't get a EXACT (spec) replacement.
[01:52:40] <SWPadnos> true enough - but at that point, you can buy a new one to the spec you want (assuming you're charging for the stuff you make on the machine)
[01:52:42] <Jymmm> SWPadnos do you see my post on CCDE by chance?
[01:52:49] <SWPadnos> which one?
[01:52:55] <Jymmm> transformer
[01:53:01] <SWPadnos> ah - one sec
[01:53:18] <Jymmm> no biggy, I just thought that's why you responded =)
[01:53:45] <SWPadnos> nope - remembered the discussion of toroid.com when I jumped on IRC
[01:54:37] <Jymmm> SWPadnos : Ah, cool. Toroid.com seems reasonable and doens't restrict my voltage either.... just add a few more turns as needed.
[01:55:04] <SWPadnos> yep - I had seen them when researching for myself
[01:55:15] <SWPadnos> nothing big enough for me though :)
[01:55:38] <Jymmm> I called them asking where the manual download was, said they weren't sure but took my email/fax/phone number and qould get back to me.... very friendly
[01:56:00] <SWPadnos> cool.
[01:56:10] <Jymmm> SWPadnos : Well, if you need a XFMR made, this place can do it. Takes about a week.
[01:56:14] <SWPadnos> I may still get two of their big ones at some point
[01:56:31] <SWPadnos> I'd be looking in the 2 kVA range
[01:56:47] <Jymmm> medical?
[01:56:54] <SWPadnos> could get that way :)
[01:57:00] <SWPadnos> nope - just big servos
[01:57:24] <SWPadnos> 9.7A continuous, limited to 80V by the Geckos
[01:57:26] <Jymmm> sorry, they only make 10KVA toroids
[01:57:27] <SWPadnos> * 3
[01:57:51] <SWPadnos> plus more for at least one rotary axis
[01:57:58] <SWPadnos> (much smaller motor though)
[01:58:06] <Jymmm> SWPadnos: sorry, they only make 10KVA toroids
[01:58:22] <SWPadnos> I noticed you said that :)
[01:58:32] <SWPadnos> I don't care if it's a toroid or not
[01:58:42] <Jymmm> holy shit... 115 pounds for the 10KVA
[01:58:50] <SWPadnos> just 120/240 input, and 55V or so out, between 1.5 and 3 kVA
[01:59:01] <Jymmm> 2500VA 33 pounds
[01:59:14] <Jymmm> 2100VA 28.5#
[01:59:29] <SWPadnos> yeah - I have one from eBay - about 45 pounds (feels like 100 - it's really dense)
[02:01:12] <Jymmm> See, you're running a lot bigger and much harder to replace if something happens. That was my issue with ebay/surplus stuff in this respect. Big caps you can find anywhere (or even wire in parallel if need be) but transformers are a bitch to come by.
[02:02:06] <SWPadnos> my thought was to get the machine running and generating income, then I can replace things with "real" parts
[02:02:51] <Jymmm> That makes sene too, I just dont want to muck with retweaking later on down the road if it'a already working.
[02:03:08] <Jymmm> a variac and isolation transformer would work for me =)
[02:04:21] <Jymmm> I STILL dont know the VA I REALLY need,
[02:04:33] <Jymmm> 400Va is safe, but....
[02:04:38] <Jymmm> so I understand.
[02:05:50] <SWPadnos> yeah - the specs on those motors don't tell me enough
[02:05:59] <Jymmm> what would you need to know?
[02:06:01] <SWPadnos> (they might tell an expert enough, but not me)
[02:06:23] <SWPadnos> well - when I look at the power requirement, it just looks like it's too low, like by a factor of 100
[02:07:03] <SWPadnos> 2.8A, 1.13 ohm = 8.86 W per phase
[02:07:33] <SWPadnos> multiply by 2 because both phases are on, and you get a whopping 17.72 W per motor
[02:08:06] <SWPadnos> that's 0.023 HP - sounds like nothing to me
[02:08:57] <SWPadnos> I'm sure there's something about the dynamic power requirements of stepper motors that I'm forgetting here
[02:09:09] <Jymmm> heh
[02:11:36] <Jymmm> I'm trying to pull up the full data for them...
[02:15:13] <Jymmm> holding torque (2 phases on) 1.9N m
[02:18:28] <SWPadnos> that's where the 269 oz-in number comes from
[02:18:33] <SWPadnos> (268.8, actually)
[02:19:30] <Jymmm> ok, what ya need to know? I have a (pathetic) datasheet in front of me
[02:19:47] <Jymmm> it's a 2 phase motor
[02:19:49] <SWPadnos> heh - I don't know what I need to know
[02:21:03] <Jymmm> see 55VDC is about 40VAC. 50 being safe, and 60 pushing it.
[02:21:20] <SWPadnos> which drives?
[02:21:26] <Jymmm> geckos
[02:21:35] <SWPadnos> G202?
[02:21:51] <Jymmm> Yeah aka Vampire LITE
[02:22:05] <Jymmm> or VampireJR =)
[02:22:23] <SWPadnos> actually, for either the G201 or G202 (and their PLL-enhanced brothers), 20-25x the motor voltage is recommended
[02:22:36] <SWPadnos> so 60-75V should be fine with any Gecko drive
[02:22:48] <Jymmm> I was thinking about using a USC board and the 202's
[02:22:53] <SWPadnos> unles sthe motor heats up too much, and you don't need the added high-end speed
[02:23:26] <Jymmm> Well, if the only diff in performance is a XFMR, I dont mind putting in a lil extra for that.
[02:23:46] <SWPadnos> it'll depend on the motors
[02:23:52] <Jymmm> I wish I knew how to convert VA to watts
[02:24:16] <SWPadnos> though the G202 may have the lower standby heating feature of the Vampire - I don't remember
[02:24:35] <SWPadnos> well - you either divide by 1.8 or by 1.4
[02:24:56] <Jymmm> 1.8 to determine the VA needed
[02:25:08] <Jymmm> 1.4 for the voltage.
[02:25:16] <SWPadnos> 1.4 is for a "direct" conversion, and 1.8 takes into account some property of transformers when used with bridge rectifiers
[02:25:18] <Jymmm> That's what I was told by the xfmr mfg today
[02:25:29] <Jymmm> yep, that's what he said
[02:25:53] <SWPadnos> I think they derate the power due to the current profile into a bridge rectifier (lots of high current spikes)
[02:25:58] <Jymmm> cause he asked "2 or 4 diode bridge?" I said 4, he said 1.8
[02:27:01] <SWPadnos> right - you get all 120 current spikes - no time for the coils to rest
[02:27:57] <Jymmm> heh
[02:28:38] <Jymmm> If I could get my hands on a nice 500VA + isolation xfmr and a variac, I could just dial in what I needed.
[02:28:54] <SWPadnos> great for testing, not necessarily for the final system
[02:29:15] <SWPadnos> no point in losing power in the variac once you know the right voltage
[02:29:35] <SWPadnos> (not to mention that it adds another 25 pounds to the control cabinet)
[02:29:40] <Jymmm> lol
[02:29:53] <Jymmm> especially this one being 2000Watts =)
[02:29:59] <SWPadnos> oh - 35 pounds
[02:30:22] <Jymmm> But damn it all to hell with finding the EXACT xfmr... I could go by damn weight iof the things then
[02:30:39] <Jymmm> If they only marked xfmr's properly there would be no issues.
[02:31:16] <SWPadnos> you can go by weight for the VA rating (for the most part)
[02:31:26] <Jymmm> yeah, that's what I mean
[02:31:37] <SWPadnos> just not for the current capacity
[02:31:58] <Jymmm> bah humbug... gonna kick some mfg ass!!!
[02:32:11] <SWPadnos> yo - get down wit it, shit!
[02:32:21] <Jymmm> no doubt!
[02:32:30] <SWPadnos> you da man, yo!
[02:32:59] <SWPadnos> he be callin' dem up sayin "yo face on fire" - bro be ON!
[02:33:02] <Jymmm> I'm gonna pop a hi-pot cap in yo ass!
[02:33:31] <SWPadnos> shee-it - don' it sound like a fukkin par-TAY!
[02:34:35] <SWPadnos> (it's so hard to spell the jive / ghetto voice)
[02:34:44] <Jymmm> lol
[02:35:08] <Jymmm> 2x24V 600VA $120
[02:35:31] <SWPadnos> OK - $23.99 including shipping for a 50VA fused control transformer - now I can get back to the Digi-Key order
[02:50:12] <les> back for a bit
[02:50:20] <les> ah jon answered
[02:50:31] <les> heh
[02:50:46] <les> he says he will test it
[02:51:06] <SWPadnos> yep - note that he normally runs at low speeds - that may be the clue
[02:52:00] <les> and...he is running a fourth order system with a tach feedback velocity amp...that dramatically lowers bandwidth and smooths things
[02:52:57] <SWPadnos> hmmm - but he wouldn't be able to mill corners if that were a problem
[02:53:11] <SWPadnos> (or a solution for the blemding case)
[02:53:48] <les> centripedal accel...V^2/r.... HUGE difference between 15 ipm and 400
[02:54:26] <SWPadnos> of course
[02:54:30] <les> he runs at 5 inches per sec squared
[02:54:38] <les> I run ten times that
[02:55:14] <les> I would run 50 times that if the TP wasn't broken
[02:56:19] <SWPadnos> heh
[03:02:45] <les> I put the code rem in the reply....but in a "fix not fight" tone. I said it might not bre relevant.
[03:03:06] <SWPadnos> ah - cool.
[03:04:15] <SWPadnos> well - time for me to run - see you guys later
[03:04:20] <SWPadnos> SWPadnos is now known as SWP_Away
[06:43:40] <Jymmm> hey LawrenceG!
[07:24:06] <anonimasu__> hello
[07:24:19] <anonimasu__> anonimasu__ is now known as anonimasu_
[07:39:48] <anonimasu_> blah, why is solidworks so good.
[07:40:45] <Jymmm> heh
[07:41:09] <anonimasu_> it decimates solidedge..
[07:41:24] <anonimasu_> but solidedge can do more stuff, and are probably a better program overall but drawing in it is so hard
[07:41:51] <anonimasu_> I've drawn a lathe toolchanger :)
[07:42:23] <anonimasu_> although not in solidworks yet, as I dont have a normal mouse(no wheel or 3rd button) ..
[07:43:18] <anonimasu_> I'll take some material off work later and machine it..
[07:44:19] <anonimasu_> not that I need a toolchanger..
[07:44:31] <anonimasu_> but I need to practice machining
[07:44:47] <Jymmm> lol
[07:45:07] <anonimasu_> I found some pretty nice drawing yesterdat at cnczone and some movie on how a real toolchanger works..
[07:45:16] <anonimasu_> it's a large cylinder basically with lock pins..
[07:45:24] <anonimasu_> you push the tool plate out..
[07:45:41] <anonimasu_> rotate it with the motor, and apply pressure until it snaps back onto the lock pins
[07:46:30] <Jymmm> when you draw it up, let me know.
[07:46:50] <anonimasu_> hm, I could draw it up now
[07:47:10] <anonimasu_> not with the motor, since I need to design a coupling
[07:49:11] <Jymmm> Well, hutty up and design it, so I can steal the design for my own personal gain!
[07:49:30] <anonimasu_> lol
[07:49:37] <anonimasu_> I've got the housing drawn now
[07:50:08] <Jymmm> have you ever heard of 'Robin Subaru' generators?
[07:50:51] <anonimasu_> no
[07:51:09] <Jymmm> me neither --> http://www.robinamerica.com/generators/class.lasso?Class=Inverter-Silent
[07:51:23] <Jymmm> I guess competition for Honda's
[07:52:15] <Jymmm> heh, you can even get a keychain remote-start for it
[07:52:46] <anonimasu_> got the piston drawn now
[07:54:32] <anonimasu_> cute :)
[07:54:57] <Jymmm> sorta nice, if it's mounted on teh roof of an RV or something like that.
[07:59:49] <anonimasu_> yep
[08:02:23] <anonimasu_> I've got it drawn now
[08:02:25] <anonimasu_> just finishing up some
[08:03:39] <Jymmm> cool! I think I'm gonna call it a night! cya
[08:04:10] <anonimasu_> ah well..
[08:04:21] <anonimasu_> if you want to see it I can post it now
[08:12:56] <anonimasu_> ah well..
[09:09:15] <anonimasu_> * anonimasu_ yawns
[09:34:31] <Jacky^> morning
[09:34:45] <anonimasu_> morning jacky
[09:34:54] <Jacky^> hi anonimasu_ :)
[09:35:01] <anonimasu_> what's up?
[09:35:50] <Jacky^> this morning i'm looking for a way to shape inbound network traffic on a server of friend..
[09:36:04] <anonimasu_> ok
[09:36:07] <anonimasu_> nice
[09:36:08] <anonimasu_> :)
[09:36:30] <Jacky^> i've not experience .. :(
[09:36:55] <anonimasu_> what operating system?
[09:37:08] <Jacky^> this evening I will have some nice wood material i ordered yesterday
[09:37:10] <anonimasu_> linux or bsd?
[09:37:24] <Jacky^> linux, debian linux
[09:38:40] <Jacky^> he want to shape network traffic on some eth subnet
[09:39:30] <Jacky^> he have an Internet point here..
[10:35:53] <anonimasu_> hm
[10:35:57] <anonimasu_> ok
[10:41:01] <dpy> hi guys
[10:42:09] <dpy> any of you who know CNC milling: is there is need for some sort of switch (microswitch) at the beginning of each axis ?
[10:42:25] <dpy> like a reset or recalibration switch or anything ?
[10:54:10] <anonimasu_> if you want to home your machine..
[11:07:00] <alex_joni> morning
[11:07:43] <anonimasu_> morning alex
[11:07:48] <alex_joni> hey anders
[11:07:51] <anonimasu_> how's things going?
[11:08:02] <anonimasu_> I am back to work again, solving this memory issue again
[11:10:17] <alex_joni> bugger that ;)
[11:10:39] <anonimasu_> heh
[11:10:49] <alex_joni> yeah
[11:10:50] <alex_joni> same here
[11:10:51] <anonimasu_> customer demand, cant bugger it ;/
[11:10:53] <alex_joni> back to work
[11:11:00] <alex_joni> getting back in shape
[11:11:22] <anonimasu_> nice
[11:15:13] <anonimasu_> I thought you had vacation to get back in shape ;)
[11:16:04] <alex_joni> heh
[11:16:12] <alex_joni> but you need a vacation after the vacation aswell
[11:16:22] <anonimasu_> :D
[11:16:36] <anonimasu_> I started designing a lathe toolchanger.. that I am going to machine tonight
[11:17:22] <anonimasu_> looked up a large block of iron for the body a bit ago..
[11:17:39] <anonimasu_> I am just messing with the motor coupling in my head
[11:18:05] <anonimasu_> I'd need splines within the changer disc
[11:18:12] <anonimasu_> and I cant make splines :D
[11:30:50] <dpy> do you guys have large hobby space ?
[11:31:13] <alex_joni> not really
[11:34:13] <dpy> say, does the idea of a reference switch in a CNC mill sound familiar ?
[11:35:49] <dpy> I have some old joystick microswitches
[11:35:57] <dpy> would those suffice
[11:45:07] <alex_joni> depends on what you need
[11:45:26] <alex_joni> if you need very high accuracy then probably it won't
[11:45:34] <alex_joni> usually it's called a home-switch
[11:45:54] <alex_joni> and it does get implemented as a mechanical switch combined with an optical reference signal on the encoder
[11:46:03] <alex_joni> at least on the serious setup's
[11:56:16] <anonimasu_> * anonimasu_ has
[11:56:27] <anonimasu_> about 100m2
[11:57:15] <alex_joni> nice
[11:57:20] <alex_joni> I need an ISA pc ;)
[11:57:26] <alex_joni> gotta see what I can come up with
[11:57:28] <anonimasu_> but it's cramped..
[11:57:37] <alex_joni> cramped?
[11:57:38] <alex_joni> :D
[11:57:41] <anonimasu_> yeah
[11:57:44] <alex_joni> sounds like belly-ache
[11:57:45] <alex_joni> :D
[11:57:56] <anonimasu_> lathe & lathe & mill + a car
[11:58:13] <alex_joni> heh, nice
[11:58:24] <anonimasu_> the mill takes up most space
[11:58:25] <anonimasu_> :)
[11:58:43] <alex_joni> make it smaller ;)
[11:58:47] <anonimasu_> heh
[11:58:48] <anonimasu_> no way
[11:58:58] <anonimasu_> my mother suggested to get rid of the attic..
[11:59:02] <anonimasu_> so I could fit a large mill ;)
[12:00:19] <anonimasu_> but that'd way too much work
[12:00:51] <alex_joni> lol
[12:00:51] <alex_joni> nice
[12:06:30] <anonimasu_> *yawns*
[12:07:51] <alex_joni> ditto
[12:10:00] <anonimasu_> the fun part starts when I am going to mill the 10x10x10mm iron cube for the toolchanger
[12:10:07] <anonimasu_> err cm
[12:24:17] <anonimasu_> re
[16:58:08] <Jacky^> hi
[16:58:14] <Jacky^> j #iptables
[16:58:18] <Jacky^> :\
[18:00:43] <alex_joni> anonimasu: around?
[18:03:37] <alex_joni> alex_joni is now known as alex_joni_rb
[18:16:21] <anonimasu> yes
[18:16:31] <anonimasu> * anonimasu has milles one side of the iron cube yet
[18:24:50] <Jymmm> Yo People!
[18:27:55] <anonimasu> hey jymm
[18:28:02] <anonimasu> * anonimasu has stuff for a huydralic spindle now
[18:28:31] <Jymmm> what happened to the pigeon powered spindle?
[18:28:56] <anonimasu> I dont know about your spindle but mine isnt pigeon powered
[18:29:09] <anonimasu> I've got a 4kw electric motor to spare..
[18:29:32] <Jymmm> What a waste... pigeon power in NY would be awesome!
[18:29:45] <anonimasu> too bad I live in another country ;D
[18:30:35] <Jymmm> Come to America!
[18:30:54] <anonimasu> I'd rather clean myself with napalm.
[18:31:21] <Jymmm> Not to worry.... the TSA will do that for you and procide 8x10 glossies to boot!
[18:31:33] <Jymmm> provide
[18:36:50] <Jymmm> stuff as in parts or drawings?
[18:38:08] <alex_joni_rb> alex_joni_rb is now known as alex_joni
[18:44:41] <les> oww what is going on with this arcblend stuff
[18:44:45] <alex_joni> hey les
[18:44:51] <alex_joni> having problems?
[18:44:52] <les> hi alex
[18:45:05] <alex_joni> I was wondering
[18:45:13] <alex_joni> what did you do with that board you got?
[18:45:13] <les> we have two emcs that don't blend arcs and two that do
[18:45:29] <alex_joni> huh.. what versions?
[18:45:47] <les> nothing..had to back burner it due to research job
[18:45:59] <alex_joni> oh.. right
[18:46:10] <les> not sure...the two that blend are very old....pre 2000
[18:46:30] <alex_joni> emc1 from cvs?
[18:46:41] <les> yeah
[18:46:59] <les> was checking tp.c and tc.c
[18:47:26] <alex_joni> can you give me some version numbers?
[18:47:30] <alex_joni> on the ones that work?
[18:47:42] <les> in 2000 a mod was made hard coding exact stop in corners over 90 degrees ieven if g64 contouring was on
[18:47:57] <alex_joni> ouch
[18:48:08] <les> I think it might not get reset
[18:48:25] <les> do you get the emc lists?
[18:48:36] <les> it 's in the posts
[18:50:21] <alex_joni> in the 2000 posts?
[18:50:24] <alex_joni> or in current ones?
[18:51:00] <les> the current ones...today and yeasterday
[18:51:08] <les> the user list
[18:51:09] <alex_joni> didn't chec those
[18:51:11] <alex_joni> lemme check
[18:51:14] <les> k
[18:51:26] <alex_joni> I don't read much user lists
[18:51:28] <les> cradek you there?
[18:52:34] <alex_joni> he's been idle for a while
[18:52:45] <les> ok
[18:56:07] <les> well I have to go out for a bit....my grandma called and needs a ride to the pharmacy
[18:56:11] <les> she is 98
[18:56:44] <alex_joni> oh.. nice age
[18:56:49] <alex_joni> best wishes for her
[18:56:51] <les> back in a little bit
[18:59:13] <cradek> back now
[19:01:33] <alex_joni> how's blending working for you?
[19:01:50] <alex_joni> e.g. linear-arc-linear
[19:03:37] <cradek> I think stuff that old isn't necessarily in rcs
[19:03:39] <cradek> err, cvs
[19:04:20] <alex_joni> tp and tc date back to 14.jun.2000
[19:04:55] <cradek> you you were talking to me, sorry
[19:05:09] <cradek> my machine is slow velocity + high accel so I don't really notice blended vs. not blended
[19:05:16] <alex_joni> right
[19:05:29] <cradek> it accels to full speed in a tiny fraction of a second
[19:06:27] <cradek> if someone gets ahold of a copy of the files that blend, I could fix it in the cradek_stable branch of emc1
[19:06:43] <cradek> I don't want those recent interpreter changes so I branched
[19:07:40] <alex_joni> I agree
[19:07:50] <alex_joni> well les started this
[19:07:55] <alex_joni> les: still around?
[19:08:03] <cradek> he said he'd be back in a bit
[19:08:11] <alex_joni> oh right
[19:08:13] <alex_joni> forgot ;)
[19:08:16] <alex_joni> getting old :(
[19:08:21] <cradek> not as old as 98
[19:08:27] <alex_joni> definately
[19:08:29] <alex_joni> not yet
[19:10:19] <alex_joni> did you try emc2 lately?
[19:14:56] <alex_joni> darn.. my home PC doesn't have ISA any more :(
[19:15:59] <cradek> I'm hanging onto my last fast ISA motherboard (500-700 MHz iirc)
[19:16:31] <alex_joni> yeah.. gotta get me an ISA PC
[19:16:39] <alex_joni> I wanted to start working on the STG
[19:16:49] <cradek> that would be nice, but I can't afford it
[19:17:02] <alex_joni> what? a STG?
[19:17:12] <cradek> yeah
[19:17:22] <cradek> with the other necessary parts to run my mill...
[19:17:23] <alex_joni> or the whole servo setup?
[19:17:27] <cradek> that
[19:19:55] <alex_joni> yeah.. that tends to get expensive
[19:20:00] <alex_joni> and not suited for home use
[19:21:52] <cradek> huh, just reading the thread again: if arc blending is just broken/buggy I can probably fix it. I'm a good bug squasher.
[19:22:08] <alex_joni> I noticed ;)
[19:22:12] <cradek> ha, thanks
[19:22:23] <cradek> I don't really do anything else though, unlike you
[19:22:52] <alex_joni> heh, not that true
[19:23:33] <alex_joni> you do plenty of stuff ;)
[19:23:36] <alex_joni> e.g. axis
[19:23:59] <cradek> yeah, but I bet it doesn't even work on emc2
[19:24:10] <alex_joni> yes it does :P
[19:24:11] <cradek> I put in the first axis-specific emc hack (in emc1/cradek_stable)
[19:24:18] <cradek> oh, cool
[19:24:22] <alex_joni> it did
[19:24:23] <alex_joni> :)
[19:24:26] <cradek> yeah, did
[19:24:27] <alex_joni> didn't check it in a while
[19:24:28] <cradek> moving target
[19:24:36] <alex_joni> but the last I checked, worked
[19:24:52] <alex_joni> it'll probably get busted along the NML rework (when that'll happen)
[19:24:57] <alex_joni> but so will all GUI's
[19:28:29] <alex_joni> ok.. I have to drive a friend to the trainstation
[19:28:34] <alex_joni> back in an hour or so
[19:28:41] <alex_joni> later
[20:17:33] <alex_joni> hmm.. pretty quiet
[20:17:39] <alex_joni> thought I'll have lots to read up
[20:19:13] <anonimasu> hm
[20:19:14] <anonimasu> ok
[20:20:13] <anonimasu> * anonimasu is having a cup of tea
[20:20:17] <alex_joni> nice
[20:20:41] <anonimasu> I decided to turn the toolchanger pneumatic part tomorrow afternoon at work..
[20:20:58] <anonimasu> the internal cylinder :)
[20:21:08] <alex_joni> cool
[20:21:09] <anonimasu> it'll be 60x faster then milling the hole..
[20:21:18] <anonimasu> I designed a toolchanger :)
[20:21:23] <anonimasu> designed/stole/adapted
[20:21:38] <alex_joni> sounds ok for me ;)
[20:22:02] <anonimasu> yeah
[20:22:17] <anonimasu> * anonimasu is 50% on the way to adapting the new lathe to cnc ;)
[20:22:49] <anonimasu> or rather, I've overcome 50% of the mental resistance that keeps me from doing it..
[20:23:00] <alex_joni> LOL
[20:23:07] <anonimasu> * anonimasu convinces anonimasu that he's in need of a cnc lathe
[20:23:27] <anonimasu> oh, even if I dont do it, a pneumatic toolchanger is nice to haev
[20:23:28] <anonimasu> have
[20:23:38] <alex_joni> and fun to use on the new CL stuff
[20:23:42] <anonimasu> heh
[20:23:52] <anonimasu> I have a plc on the shelve here..
[20:23:57] <anonimasu> I am not touching cl ;)
[20:23:57] <alex_joni> hope you'll gonna emc it
[20:24:00] <alex_joni> why not?
[20:24:04] <anonimasu> oh, I have a real plc..
[20:24:18] <anonimasu> the lathe?
[20:24:25] <alex_joni> yup
[20:24:28] <anonimasu> ah I wish
[20:24:39] <alex_joni> well... step 1. dream
[20:24:42] <anonimasu> I might use cl for the toolchanger.. depends
[20:24:46] <alex_joni> step 2. wake up
[20:24:49] <anonimasu> yeah..
[20:24:50] <alex_joni> step 3. make it happen
[20:24:51] <alex_joni> :D
[20:25:00] <anonimasu> I usually end up finishing stuff..
[20:25:24] <anonimasu> but, lately *sigh*
[20:25:25] <alex_joni> well.. the tricky part is to start smthg
[20:25:28] <anonimasu> yeah
[20:25:44] <anonimasu> well, I've got the material for the toolchanger it's 40% of the work to square it
[20:26:10] <alex_joni> talking about dreaming ;)
[20:26:13] <anonimasu> heh
[20:26:18] <anonimasu> yeah
[20:26:19] <dreamer_> dreamer_ is now known as _dreamer
[20:26:48] <_dreamer> hi
[20:27:14] <Imperator_> Hi all
[20:27:35] <alex_joni> hey martin
[20:27:38] <alex_joni> hi _dreamer
[20:28:08] <Imperator_> whats going on ?
[20:28:27] <alex_joni> not much
[20:28:36] <alex_joni> started working on the STG
[20:28:41] <alex_joni> err.. wanted to start
[20:28:47] <Imperator_> hehe
[20:28:48] <alex_joni> but noticed I got no ISA slot here :)
[20:28:56] <_dreamer> I just got 3 3600 cycles per turn encoders. I got nothing to hook them up to. Could i test them by putting a power source to them and then hooking up an rms meter or something to the output pins?
[20:28:56] <Imperator_> ups
[20:29:18] <alex_joni> _dreamer: what else do you have besides RMS meter?
[20:29:19] <Imperator_> you need a oszy
[20:29:19] <anonimasu> hm, if you have a impulse counter..
[20:29:25] <alex_joni> a scope would be great
[20:29:33] <alex_joni> but RMS _should_ do the trick
[20:29:34] <anonimasu> some meters do show HZ
[20:29:39] <_dreamer> nope, no impulse counter. no scope. still a newbie
[20:29:51] <_dreamer> just rms meter and a few other junks
[20:29:57] <alex_joni> some of the meters have counters
[20:30:01] <alex_joni> but RMS might be ok
[20:30:04] <alex_joni> you
[20:30:06] <anonimasu> my lost meter.. *cry*
[20:30:14] <alex_joni> you'll only see that it works
[20:30:17] <alex_joni> not if it works ok
[20:30:35] <Imperator_> * Imperator_ trys to find out how to start a project with the Xilinx FPGA software
[20:30:36] <alex_joni> I suppose these are quadrature
[20:30:49] <alex_joni> usually #include's ;)
[20:31:19] <_dreamer> hm, yep. yes, quadrature. also says has differential outputs.
[20:31:29] <alex_joni> quadrature is best
[20:31:36] <alex_joni> most widely spread
[20:31:48] <alex_joni> connect the meter to the/a quadrature output
[20:31:53] <alex_joni> and turn it very slowly
[20:32:01] <alex_joni> you might see it toggle from 0V to 5V
[20:32:08] <alex_joni> if 5V is your power supply
[20:33:35] <alex_joni> usually the better ones have 2 quadrature outputs
[20:33:43] <alex_joni> A/notA and B/notB
[20:33:47] <alex_joni> and the index pulse
[20:34:12] <_dreamer> yes, it has a/not a and b/not b
[20:34:19] <alex_joni> no index?
[20:34:20] <_dreamer> however, I don't see a pin for index pulse, so I don't think it has it?
[20:34:25] <alex_joni> probably not
[20:34:32] <alex_joni> is it open?
[20:34:49] <alex_joni> you could check the disk, the index pulse is pretty visible to the trained eye ;)
[20:35:09] <alex_joni> _dreamer: do you have a working linux with rt?
[20:35:41] <_dreamer> nope, not open. I have linux bbuntu on this box right now
[20:35:44] <_dreamer> ubuntu
[20:35:52] <alex_joni> you might connect the encoder directly to the parport
[20:35:59] <alex_joni> and use a emc2 component to see if it works
[20:36:13] <alex_joni> but I would definately first try the RMS meter
[20:36:41] <_dreamer> I have to get my power supply from home first :P
[20:37:13] <_dreamer> this encoder is weird. it takes a 8-15VDC unregulated power supply as opposed to the normal 5V
[20:37:23] <alex_joni> ohh.. nasty
[20:38:08] <_dreamer> I have a 15V regulated power supply. I was planning on shielding everything.
[20:38:25] <_dreamer> I would think if it requires unregulated power supply, it must have some kind of filtering capacity within it'
[20:38:36] <alex_joni> yeah.. but it shouldn't matter
[20:38:47] <Jacky^> hello
[20:38:51] <_dreamer> hi
[20:38:54] <alex_joni> if you supply regulated power to a device that expects unregulated, it should work
[20:41:49] <Jacky^> alex_joni: stepper controller PS ?
[20:41:54] <les> back. whew it's hot. heat wave.
[20:42:42] <alex_joni> wb les
[20:42:46] <alex_joni> cradek is also around
[20:42:53] <les> oh good
[20:43:30] <les> and...make rc high pass to check the encoder with rms meter. turn it faster and signal will increase.
[20:44:28] <cradek> les: finally cooled off here - it was over 100 for a couple weeks, now it's 75
[20:44:49] <alex_joni> it was 35 celsius today here
[20:44:52] <cradek> after a very strong storm yesterday
[20:44:54] <alex_joni> not a lot cooler now
[20:44:55] <alex_joni> :(
[20:45:14] <les> beglad when the front gets here
[20:45:18] <cradek> alex_joni: we had 40 for weeks
[20:45:23] <alex_joni> ouch
[20:45:32] <alex_joni> ok.. back to serious stuff ;)
[20:45:37] <alex_joni> line-arc-line blending
[20:45:46] <alex_joni> and other arc- related blendings :P
[20:45:49] <les> well you saw my comment?
[20:46:11] <les> about perhaps the over 90 degree exact stop thing?
[20:46:17] <cradek> yeah
[20:47:07] <les> I have made a test program...series of connected arc s curves
[20:47:10] <les> joined
[20:47:22] <les> then an over 90 corner
[20:47:34] <les> then another series of s curves
[20:48:18] <les> the exact stop is a pain...chip load goes to zero and it burns
[20:48:41] <cradek> so what does your test program do?
[20:48:57] <les> just runs through those motions
[20:49:04] <cradek> I mean, does it blend?
[20:49:08] <Imperator_> Les: what type of hardware do you have, I meen how are you commanding your amps
[20:49:24] <les> have not tried it...had to go to town. just got back.
[20:49:36] <les> ok
[20:49:39] <les> stg
[20:49:43] <les> servo
[20:49:59] <les> pid torque mode
[20:50:19] <les> amps are voltage controlled current sources
[20:50:35] <les> in other words the usual
[20:50:36] <Imperator_> +-10v output of the stg card to the amps
[20:50:52] <les> yeah. 10v=20 amps.
[20:51:22] <Imperator_> hm
[20:51:23] <les> even have current and voltage meters on the pasnel
[20:52:05] <Imperator_> have no machine but some servos also commanded via +-10V signal, what i can test with them seams not that bad
[20:52:13] <les> Torque mode is normal these days, and totally quiet and smooth
[20:52:25] <les> must use D term though
[20:53:24] <les> As opposed to the old velocity mode amps used many years ago...must not use D
[20:53:43] <les> OMG
[20:53:43] <alex_joni> greetings paul_c
[20:53:46] <Jacky^> ue' paul_c
[20:53:47] <alex_joni> yeah..
[20:53:55] <alex_joni> paul_c: quick, hide ;)
[20:54:08] <les> hahaha
[20:54:14] <Jacky^> doh
[20:54:21] <Imperator_> Hi Paul
[20:55:01] <paul_c> Evening folks.
[20:57:18] <les> we have both beenqaway for a bit paul
[20:57:30] <les> I have been busy with a research gig.
[20:58:34] <les> You have been away writing heptic trajectory planners...
[21:00:06] <paul_c> heptic, no. hectic, maybe.
[21:00:13] <les> haha
[21:00:50] <les> dodecahedric...oops non symetrical boundary conditions haha
[21:00:57] <alex_joni> lol
[21:01:41] <les> get the order high enough and it will just be point to point!
[21:02:35] <alex_joni> and you'll end up having processing power for about 1-2 steps / second anyhow ;)
[21:02:43] <les> heh
[21:03:30] <Imperator_> for the meas fpga board is a soft DSP available, maybe that helps
[21:04:10] <les> Well I just have to keep at this energy harvesting thing...but client wants to violate laws of thermodynamics I fear
[21:04:40] <robin_sz> maweeep?
[21:04:45] <les> hey.
[21:04:53] <robin_sz> hows it hanging?
[21:05:04] <les> low. it's hot here.
[21:05:11] <robin_sz> wet here
[21:05:22] <alex_joni> hot here too
[21:06:15] <Jacky^> hi robin_sz :)
[21:06:31] <Jacky^> here is cold
[21:06:37] <Jacky^> 24�
[21:06:57] <Jacky^> with conditioner air fresh 18000 btu :P
[21:07:19] <Jacky^> out is 40 :\
[21:07:41] <alex_joni> had about 35 today
[21:07:56] <les> 37 here
[21:08:06] <alex_joni> Jacky^: I run a 24000 at work ;)
[21:08:08] <les> 42 at low elevation
[21:08:31] <Jacky^> alex_joni: it's a paradise
[21:08:32] <robin_sz> mushroom mushroom
[21:08:36] <Jacky^> ahhh :)
[21:08:42] <alex_joni> Jacky^: not really
[21:08:46] <alex_joni> it's too strong
[21:08:50] <alex_joni> getting headaches
[21:09:06] <Jacky^> of course, depend on the room..
[21:09:10] <alex_joni> I'm running it at 26-27 degrees on economy mode, with low fan and still it's a bit much
[21:09:16] <alex_joni> about 60-70 m^2
[21:09:30] <Jacky^> depend on many other thing
[21:09:33] <Jacky^> isolament
[21:09:47] <Jacky^> if up there's another floor ..
[21:09:53] <Jacky^> or not
[21:10:29] <Jacky^> in some case also 7000 BTU can work fine
[21:10:36] <Jacky^> not here ..
[21:10:44] <Jacky^> absolutely
[21:10:57] <Jacky^> :(
[21:12:18] <alex_joni> http://www.futurebots.com/gmotor.jpg <- nice motor
[21:12:58] <alex_joni> dc motor, dc brake and encoder
[21:13:35] <alex_joni> err.. tach not encoder
[21:16:19] <alex_joni> logger_aj, wb ;)
[21:16:19] <alex_joni> I'm logging. I don't understand 'wb ;)', alex_joni. Try /msg logger_aj help
[21:20:29] <robin_sz> btu ...
[21:20:44] <robin_sz> isnt that a measuremnt related to the heat output of a steam engine?
[21:20:52] <alex_joni> that's british thermal units
[21:20:58] <alex_joni> thought you'd know
[21:20:59] <robin_sz> wow ...
[21:21:05] <robin_sz> I dont think we use them over here
[21:21:13] <robin_sz> kw
[21:21:31] <alex_joni> but no.. brits are just not using new stuff
[21:21:37] <alex_joni> even if it's named after them
[21:21:39] <alex_joni> lol
[21:21:58] <robin_sz> new? i think I remember gas bills using it some 20 years ago
[21:22:24] <Jacky^> nah..
[21:22:30] <alex_joni> well.. "new"
[21:22:31] <robin_sz> but all chillers are rated in kw
[21:22:35] <alex_joni> or different
[21:23:04] <alex_joni> probably saner that way ;)
[21:23:14] <robin_sz> well .. maybe
[21:23:27] <alex_joni> I have no idea how much power a 24kBTU cooler drains
[21:23:32] <robin_sz> peopel will get confused between heat pump rates and energy consumption
[21:23:45] <anonimasu> * anonimasu just tried flycutting with a boring head
[21:23:50] <robin_sz> I know how much my 45kw one pulls ...
[21:23:54] <anonimasu> the surface got a mirror finish :)
[21:23:59] <anonimasu> just 0.03 per pass though
[21:24:09] <anonimasu> for the roughing pass
[21:24:11] <robin_sz> 37A of 415V 3 phase
[21:24:55] <robin_sz> as Iundertand it . btu are like joules ...
[21:25:07] <robin_sz> so is that 24K btu / hour or a minute?
[21:26:46] <Jacky^> 1 BTU = 1055 Joule.
[21:27:31] <anonimasu> * anonimasu is looking forward until he can machine more at the toolchanger :)
[21:28:00] <Jacky^> anonimasu: is the toolchanger ready to work ?
[21:28:11] <alex_joni> at this rate?
[21:28:13] <anonimasu> Jacky^: oh, I endedup building one for the lathe
[21:28:15] <alex_joni> probably never will be
[21:28:19] <alex_joni> lol
[21:28:26] <Jacky^> ouch :s
[21:28:29] <alex_joni> anonimasu: just pulling your leg ;)
[21:28:30] <Jacky^> no..
[21:28:48] <Jacky^> you will share youre project :P
[21:28:52] <anonimasu> no
[21:28:53] <anonimasu> :D
[21:28:56] <Jacky^> I also need it
[21:29:00] <Jacky^> :)
[21:29:13] <alex_joni> Jacky^: you might be able to buy it
[21:29:19] <alex_joni> especially if it doesn't work
[21:29:20] <alex_joni> :D
[21:29:35] <Jacky^> ghghgh :(
[21:31:49] <Jacky^> I believe in anonimasu :)
[21:32:05] <Jacky^> he's strong :P
[21:32:52] <anonimasu> lol
[21:32:54] <anonimasu> it's a simple design
[21:33:07] <Jacky^> it's a great idea :)
[21:33:08] <alex_joni> 5'3" and 160 lbs?
[21:33:13] <anonimasu> lol
[21:33:14] <robin_sz> I have a simple toolchanger for our bridgeport
[21:33:14] <anonimasu> not really
[21:33:18] <anonimasu> hand?
[21:33:22] <robin_sz> yep
[21:33:38] <anonimasu> oh, I guess you will be tending to it when doing runs of stuff over a weekend
[21:33:47] <anonimasu> :D
[21:33:55] <robin_sz> well, unless you have a part changer too ...
[21:34:09] <anonimasu> I will have someday :)
[21:34:11] <anonimasu> I dont need a toolchanger for the lathe really
[21:34:20] <robin_sz> but yeah, toolchangers are nice ...
[21:34:21] <anonimasu> it's just a nice and not too complex project to try out my skills..
[21:34:31] <anonimasu> machining anything is good practice
[21:34:34] <robin_sz> the spindle is the tricky thing
[21:34:40] <anonimasu> on the mill?
[21:34:44] <robin_sz> the button puller
[21:34:48] <robin_sz> * robin_sz nods
[21:34:50] <anonimasu> yeah
[21:34:53] <anonimasu> * anonimasu has it solved
[21:34:58] <anonimasu> I'll use the drawbar to push the tool out..
[21:35:07] <robin_sz> and finding a source of buttons
[21:35:11] <robin_sz> ahh, ok
[21:35:11] <anonimasu> * anonimasu has one
[21:35:19] <robin_sz> at a sane price?
[21:35:22] <anonimasu> yeah..
[21:35:28] <anonimasu> 30~
[21:35:30] <anonimasu> $
[21:35:34] <robin_sz> not bad ...
[21:35:36] <anonimasu> I think it was..
[21:35:42] <anonimasu> yeah
[21:35:43] <anonimasu> :)
[21:35:52] <robin_sz> they are made to a very tight spec ..
[21:35:57] <anonimasu> but since I dont have a drawbar that'll use thoose it's no use..
[21:36:01] <robin_sz> and xrayed to death
[21:36:09] <anonimasu> but I might have a huydralic spindle on the way
[21:36:23] <alex_joni> seen a nice cat scan for metals these days
[21:36:30] <anonimasu> got a 4kw motor and a pump :)
[21:36:44] <robin_sz> tasty
[21:36:51] <anonimasu> yeah should do nicer then the electric motor..
[21:37:13] <robin_sz> low speed though?
[21:37:16] <anonimasu> the huydralic motors I am going to use will handle 40kw ;)
[21:37:19] <alex_joni> robin_sz: ever seen a ct scan ?
[21:37:25] <robin_sz> yes
[21:37:26] <anonimasu> robin_sz: 4000rpm..
[21:37:39] <alex_joni> very nice
[21:37:40] <robin_sz> alex_joni: but only of humans
[21:37:46] <alex_joni> they used it for metal things
[21:37:49] <alex_joni> and scanned 3D
[21:37:54] <robin_sz> sure?
[21:38:01] <alex_joni> very sure ;)
[21:38:07] <alex_joni> I looked inside a watch
[21:38:08] <anonimasu> robin_sz: with a new column out of square construction iron..
[21:38:10] <alex_joni> very nice
[21:38:27] <alex_joni> they were taking pictures during turning the piece
[21:38:30] <robin_sz> only CT scanners I know of would not be useabkle with metal dues to high magnetic fields
[21:38:38] <alex_joni> 360 pictures
[21:38:49] <alex_joni> not sure what CT scanners use, this was x-ray based
[21:38:58] <robin_sz> ahh,
[21:39:02] <anonimasu> it'll be a while until I can begin to care about it but, it's still nicer then having a 4kw motor hanging..
[21:39:03] <robin_sz> thats different
[21:39:10] <alex_joni> about 10-20 times more powerfull than a human ct scanner
[21:39:18] <alex_joni> not sure .. just what they told me
[21:39:22] <anonimasu> or well, might be 10kw..
[21:39:27] <robin_sz> ct scans are not xray
[21:39:29] <Jacky^> ah! alex_joni do you know some nice project of homebuild 3D laser scanner ?
[21:39:36] <anonimasu> the only trouble is to cool the oill
[21:39:41] <anonimasu> s/oill/oikl
[21:39:42] <anonimasu> oil.
[21:40:03] <alex_joni> anonimasu: think I recall smthg about 4kW
[21:40:08] <alex_joni> for small objects though
[21:40:14] <alex_joni> 10 cm x 10 cm x 10 cm
[21:40:22] <anonimasu> ?!
[21:40:25] <anonimasu> ack
[21:40:27] <robin_sz> alex_joni: usually use nmr as the scan system, feeding data to the ct processor
[21:40:36] <alex_joni> right
[21:40:45] <alex_joni> robin_sz: I think this was xray
[21:40:49] <robin_sz> right
[21:40:50] <alex_joni> fed to a ct processor
[21:41:03] <robin_sz> nmr is a big magnet and some aeriels
[21:41:33] <alex_joni> I see..
[21:41:41] <alex_joni> well the nice thing was to put the images together
[21:41:45] <alex_joni> and get a 3D model
[21:41:46] <robin_sz> they wont nmr scan you if you have been in the metal industry
[21:41:55] <alex_joni> heh
[21:42:15] <robin_sz> particles of metal tend to leave the body .. by the most direct route
[21:42:33] <robin_sz> eg out through your eyes
[21:43:12] <robin_sz> my wifes seen plastic tubing float and be attracted to the magnets
[21:43:37] <alex_joni> heh
[21:45:13] <robin_sz> no .. seems Im wrong ...
[21:45:21] <robin_sz> ct is normally xray based
[21:45:31] <robin_sz> well .. there you go then
[21:47:34] <anonimasu> *yawns*
[21:47:49] <alex_joni> [00:00] <anonimasu> *yawns*
[21:48:15] <anonimasu> 22:58 here
[21:48:16] <anonimasu> ;)
[21:48:31] <anonimasu> how do you accept a refund at paypal?
[21:48:42] <anonimasu> it's marked as pending..
[21:49:14] <anonimasu> is it waiting for paypal to finish it?
[22:01:37] <Imperator_> ciao
[22:01:44] <anonimasu> later..
[22:01:49] <Jacky^> hey ciao Imperator_ :))
[22:01:58] <Imperator_> see you
[22:02:15] <Jacky^> Chatzilla 0.9.66e
[22:02:19] <Jacky^> what is ?
[22:02:32] <Jacky^> O_o
[22:02:38] <anonimasu> the stuff that comes with mozilla
[22:02:45] <Jacky^> irc client ?
[22:02:54] <anonimasu> yeah
[22:03:03] <Jacky^> mmm, never heard
[22:03:07] <Jacky^> :)
[22:03:27] <Jacky^> should be nice..
[22:13:20] <alex_joni> * alex_joni goes to bed
[22:13:22] <alex_joni> night
[22:13:22] <Yuga> hey all
