[00:00:51] <dmess> hi
[00:01:50] <les_w> had servo current on the storage scope today.
[00:02:09] <dmess> any hope??
[00:02:48] <les_w> well, I suspect when we turned off the misblending we turned off blending altogether.
[00:03:04] <les_w> no blending is not as bad a horrible misblending
[00:03:32] <les_w> not totally positive about this though.
[00:04:18] <dmess> with the correct accel / decel algorithms its the same
[00:04:45] <les_w> well I can switch from g61 to g64 and look at the scope.
[00:04:50] <les_w> that will tell.
[00:05:13] <dmess> dont blend the motion control.... control the accel/decel of a constant mass
[00:06:09] <les_w> well we have control with max>accel and amp current limiting
[00:06:18] <les_w> max_acceleration
[00:07:06] <les_w> I am not sure of this. Something is way screwed up still though.
[00:07:13] <dmess> transitional control???
[00:07:31] <dmess> s-curve...??
[00:07:34] <les_w> oh, it's something in tp/tc.c
[00:08:16] <les_w> s-curve at the trajectory level is basically a rewrite
[00:09:29] <dmess> it feels lead/lag related...
[00:09:57] <les_w> could be, but I don't think so.
[00:10:10] <les_w> lead is d term
[00:10:15] <les_w> lag is I term
[00:10:53] <dmess> tried opening "in pos'n" zove to see if blends are better...??
[00:11:15] <dmess> zone
[00:11:35] <les_w> ?
[00:11:46] <les_w> I just se nasty, nasty spikes
[00:11:49] <les_w> see
[00:12:48] <les_w> not as bad as before though
[00:12:48] <les_w> but
[00:12:48] <les_w> bad enough to trash any HSM
[00:13:10] <dmess> IF...your monitoring too SMALL a window.. its NEVER where it should be... it'll be jerky and stutter on the servo v
[00:14:13] <les_w> I am looking at fairly large windows...scope horizintal is about 1 second
[00:14:18] <dmess> but the drives accel / decel should monitor the ZONE it needs to accel/decel
[00:14:31] <les_w> servo tuning is good...1/2 cycle overshoot
[00:15:23] <les_w> have some excitation of x gantry rocking mode complex conjugate pole pair
[00:15:33] <les_w> that's mechanical
[00:16:04] <dmess> drive is suffering from data starvation...
[00:16:18] <les_w> not a software issue except for the lack of a notch filter in the pid
[00:20:15] <dmess> data overload...??
[00:20:43] <les_w> no, I don't thinkk so. I think it is math errors in the code.
[00:21:49] <dmess> math errors should should repeat.. run the same prog and record and compare...
[00:22:17] <les_w> it does
[00:22:48] <dmess> ron a large circle to see if its on all axes??
[00:23:14] <dmess> then try a small
[00:23:26] <les_w> yes. We have a special program to do just that. it is a slow helix using x,y, and z.
[00:23:49] <les_w> I did the math and paul coded it.
[00:23:56] <les_w> it does large and small
[00:24:38] <dmess> up a cone in smaller faster arcs
[00:25:00] <les_w> yes basically that is exactly what it does
[00:25:22] <les_w> We should post the code somewhere.
[00:25:30] <dmess> normal projection ON the cone
[00:25:41] <les_w> it's a simple c program that writes g code.
[00:26:07] <dmess> where were yo 15 yrs ago
[00:26:38] <dmess> its a mold runner test piece too
[00:26:41] <anonimasu> hm
[00:27:08] <les_w> 15 years...hm let me think....I was a director of reserch and development at a corporate division.
[00:27:38] <les_w> manager of research and development
[00:27:47] <les_w> must get the silly titles right!
[00:27:54] <dmess> and would NOT have given me the time of day.. i rest my case.. i got her done... ; )
[00:27:58] <Jymmm> s/research/finding the right beer/
[00:28:08] <Jymmm> s/development/bulshing contests/
[00:28:13] <Jymmm> belching
[00:28:25] <les_w> actually dmess...I might have hired you!
[00:28:28] <les_w> heh
[00:28:58] <dmess> damn... always laye for everything.... ; (
[00:29:08] <dmess> late
[00:29:28] <dmess> but i SOMETIMES get laid
[00:29:46] <les_w> huh? what's that?
[00:29:58] <les_w> hahaha
[00:30:18] <dmess> depends on th $$$ situation... LOL
[00:30:28] <Jymmm> dmess I could take that to a whole new level...
[00:30:41] <les_w> after two ex wives, I know that is true.
[00:31:18] <dmess> and im still sleepin with my wife... NOT the chick on the corner that looks pretty hot after a few pops
[00:32:07] <les_w> I am in rural georgia. It would take an awful lot of pops to make the girls look good here.
[00:32:57] <les_w> like in the "beer is good for you" thing
[00:33:31] <dmess> hypothetical situation... I walk int a whore house... i FLAKED for all my cash .. 1 of her sorry degenerate friends is the NEXT LUCKY candidate... and MY ASS IS GRASS
[00:33:49] <les_w> haha
[00:34:19] <anonimasu> f?
[00:34:49] <dmess> you want a friend list you hack me
[00:35:16] <dmess> but your BAD.... ; )
[00:35:54] <anonimasu> ?
[00:36:04] <anonimasu> dmess: stop confusing me
[00:36:39] <dmess> nah nah... your it...
[00:38:12] <Jymmm> * Jymmm reads about planers and jointers
[00:38:31] <anonimasu> it's all about having a plan before the party.
[00:40:31] <anonimasu> otherwise bad stuff happens.
[00:41:16] <CIA-6> 03rayhenry * 10emc2/configs/mazak_rf.hal: added a few more sigs
[00:42:58] <CIA-6> 03rayhenry * 10emc2/configs/mazak_rf.clp: start of tool arms
[00:50:27] <les_w> planers and jointers...hmmm
[00:50:33] <les_w> we have those.
[00:51:08] <Jymmm> Never touched either before. Just difficult to find tin wood here, so thought i might try the pallet thing.
[00:51:16] <Jymmm> thin
[00:51:37] <les_w> some pallets have very nice wood
[00:51:42] <les_w> most do not
[00:52:54] <Jymmm> Yeah; Just was looking at an alternative wood source. Guess I need to borrow an acre or two from you to store a ll this stuff =)
[00:53:04] <les_w> heh
[00:53:09] <les_w> wood for signs?
[00:53:14] <Jymmm> yeah
[00:53:23] <dmess> japanese packing crates are good
[00:53:38] <les_w> we use walnut. It's cheap, stable and carves nicely
[00:54:00] <Jymmm> dark walnut?
[00:54:03] <les_w> yes
[00:54:05] <Jymmm> err english walnut
[00:54:29] <Jymmm> dmess wouldn't know it if I saw it =)
[00:54:42] <les_w> juglans nigra...american walnit
[00:54:48] <les_w> walnut
[00:55:34] <les_w> uh...what is that identify thing? hads to reboot.
[00:55:49] <Jymmm> /ns identify <password>
[00:55:52] <les_w> ty
[00:55:58] <dmess> les... any chance of running a program in auto xyz axes.. with abc as input devices to add or negate pulses to move it all in real time??
[00:56:58] <les_w> I have not done abc....need to mess with it. I hear it has some problems
[00:57:40] <dmess> or x add pullses y negate afew...
[00:58:39] <les_w> step pulses? don't know. We do full servo.
[00:58:49] <dmess> i just think it needs to be ANOTHER type of input ... possibly and input axis??
[00:59:00] <les_w> but what you are talking about is basically feedforward
[00:59:46] <dmess> but with servo could i pull on it and have IT listen to me... and react on the other axis
[01:00:08] <dmess> ok yes...
[01:00:54] <dmess> bt i may want to slow it all down
[01:01:42] <les_w> dmess, that is a matrix feedforward...where x depend on y or similar
[01:02:40] <dmess> yes.. x is program.. y is operator input...
[01:03:44] <les_w> well, PID is basically dumb. It only knows errors. Feedforward knows the dynamics of a machine
[01:04:17] <les_w> emc has zeroth, first, and second order feedforward
[01:05:18] <dmess> thats zero.. ; (
[01:06:47] <dmess> or .. wait... its 1
[01:07:36] <les_w> output=position* feedforward term
[01:07:50] <les_w> seldom used
[01:08:06] <les_w> what is used a lot is accel feedforward....
[01:08:39] <les_w> if the structure lags due to accel forces... feedforward compensates
[01:09:01] <dmess> paragliding/hang-gliding simulator.... of baro recorded flights...
[01:09:05] <les_w> like if a fast car pressed you back in your seat...
[01:09:29] <anonimasu> les_w: what would you think about staritng a TP ducumentation project?
[01:09:32] <les_w> feedforward would move the seat up a little so you are the same distance from the steering wheel
[01:09:37] <les_w> that sort of thing
[01:09:43] <anonimasu> starting..
[01:10:32] <les_w> anders: sounds great. Might be kinda like a "unified theory" project though
[01:11:08] <les_w> I think the emc tp is structure more complicated than superstring theory
[01:11:11] <les_w> haha
[01:11:33] <les_w> I understand why that is though.
[01:51:19] <lilo> [Global Notice] Hi all. We're experiencing problems with cogent transit and we're rearranging the servers to compensate. Apologies for the inconvenience.
[02:23:44] <les_w> quiet...
[02:26:15] <miniMess> any thoughts on the flying sim idea... doable??
[02:31:41] <Jymmm> * Jymmm prefers alien flying suacer
[02:32:23] <CIA-6> 03rayhenry * 10emc2/configs/mazak_rf.clp: tool arms
[02:33:04] <CIA-6> 03rayhenry * 10emc2/configs/mazak_rf.hal: tool arms
[02:41:38] <fenn> mmm.. dumpstered sushi
[02:41:59] <fenn> m/e eats $200 worth of sushi
[02:45:38] <A-L-P-H-A> dumpstered sushi?
[02:45:41] <A-L-P-H-A> you mean dayold?
[02:45:50] <A-L-P-H-A> or same-day-old?
[02:46:40] <fenn> they throw it out the next day at 11:30
[02:47:10] <A-L-P-H-A> see...
[02:47:38] <A-L-P-H-A> Here in civilization... the sushi places if they close at 9pm... they clear out the stuff at 8pm at discount prices.
[02:47:58] <fenn> that's nice of them
[02:48:23] <A-L-P-H-A> better than wasting the food.
[02:48:31] <A-L-P-H-A> so they just sell it off cheaper.
[02:48:43] <A-L-P-H-A> cause if someone gets food poisoning, they get shut down.
[02:48:53] <A-L-P-H-A> so better to break even, then loose money, or worse.
[02:49:09] <fenn> even if the person gets the sushi out of their dumpster??
[02:49:29] <A-L-P-H-A> well, no.
[02:49:34] <A-L-P-H-A> they didn't sell it to you.
[02:49:48] <A-L-P-H-A> maybe good catfood.
[02:49:53] <A-L-P-H-A> but not human consumption.
[02:50:07] <fenn> yeah i feed it to my dog too
[02:50:16] <A-L-P-H-A> what happens if they forgot to put it in the fridge... and a human consums it.
[02:50:22] <A-L-P-H-A> what happens if you dog gets the runs?
[02:50:23] <A-L-P-H-A> eeew...
[02:50:27] <A-L-P-H-A> doggie diarhea.
[02:52:10] <fenn> i'm pretty sure most dogs can handle rotten fish pretty well
[02:53:29] <les_w> what th'
[02:53:34] <les_w> ??
[02:53:35] <les_w> haha
[02:54:43] <A-L-P-H-A> http://www.flashfunpages.com/couple.swf
[02:54:49] <les_w> rotten sushi-> dog food engineering?
[03:28:44] <Jymmm> A-L-P-H-A thats funny
[03:54:18] <A-L-P-H-A> heh. yeah.
[03:54:22] <A-L-P-H-A> some girl sent it to me.
[04:12:29] <Jymmm> if she only knew....
[21:28:27] <anonimasu> clapper?
[21:30:19] <miniMess> cnc clapper...
[21:30:30] <anonimasu> what's that?
[21:31:26] <miniMess> designer claps 2 times.. ( just like james brown) and instant part...
[21:31:56] <anonimasu> haha
[21:32:02] <anonimasu> fast sintering machines ;)
[21:32:21] <anonimasu> or something like that..
[21:33:18] <miniMess> no mind control metal removal.... it ALL in your head...
[21:33:40] <anonimasu> miniMess: lay off the crack ^_^
[21:34:47] <miniMess> no chemicals alter your synapsys and that screws wit the plc ...
[21:35:12] <miniMess> and other i/o devices
[21:37:48] <miniMess> my wife just showed me mittens for the small dog .... im dying here...
[21:38:07] <miniMess> there ARE 4
[21:38:29] <miniMess> someone SHOOT ME...
[21:38:44] <cradek> there should be 5 - one for the tail
[21:39:11] <miniMess> it never STOPS it would shed it
[21:39:41] <miniMess> PUG... i call her frank... her name is Pearl
[21:40:52] <A-L-P-H-A> hey for those that didn't see this earlier.
[21:40:56] <miniMess> there's a sweater tooo.... bring THE gun i shoot myself...
[21:41:09] <A-L-P-H-A> sexist as hell. but funny. http://www.flashfunpages.com/couple.swf *work safe*.
[21:43:45] <anonimasu> hm
[21:44:20] <miniMess> thats a keeper... wife just pounded off....
[21:45:01] <miniMess> you had the dogs and cats in shoes too.. didnt you..??
[21:45:05] <A-L-P-H-A> HEHE... I'll buy her a tim hortons coffee...
[21:45:14] <A-L-P-H-A> you're only 20 minutes away. hehehe
[21:45:26] <miniMess> she'll meet you.. you're close..
[21:45:37] <A-L-P-H-A> could meet in Ajax.
[21:45:40] <A-L-P-H-A> mid way. hehe.
[21:45:45] <A-L-P-H-A> have an affair with you wife. ;)
[21:45:50] <miniMess> she's walkin pups...
[21:46:19] <miniMess> tell me how she is?
[21:46:51] <A-L-P-H-A> heh. what happens if she's bad?
[21:46:57] <A-L-P-H-A> hahaha. j/k
[21:46:59] <A-L-P-H-A> i'll stop now
[21:47:24] <miniMess> the rings on you right hand cause if you us you left it feels like someone elas is doing it...
[21:47:47] <les_w> ha just sold something. Got a two inch thick stack'0 hundreds in my pocket. And no one to spend it on.Too bad.
[21:47:51] <miniMess> else is
[21:47:58] <anonimasu> les_w: spend it on me ;)
[21:48:09] <A-L-P-H-A> les_w... I'm your new bitch.
[21:48:14] <les_w> hahaha
[21:48:30] <A-L-P-H-A> what'd you sell?
[21:48:39] <A-L-P-H-A> how much is two inch thick stack of hundreds?
[21:48:50] <miniMess> alpha me and a chum are thinking of doing an amture nite at yuk-yuks in ajax.... can you round up a croud...
[21:49:55] <A-L-P-H-A> Dude, majority of my friends are now in Scar, Toronto. Why would they want to go Ajax?
[21:49:57] <miniMess> sold the farm??
[21:50:12] <les_w> nah...just an old car.
[21:50:12] <A-L-P-H-A> sold the ex-wifes skeletol remains.
[21:50:16] <les_w> hahaha
[21:50:18] <miniMess> for shits and giggles...??
[21:50:20] <les_w> which one?
[21:50:38] <miniMess> how old?
[21:50:57] <les_w> a first year '66 bronco sport
[21:51:02] <miniMess> wives nvolved i take it
[21:51:29] <miniMess> nice machine.. in good shape...4000
[21:51:42] <A-L-P-H-A> FUCK! stupid timmies. There's coffee grounds in my coffe.
[21:51:58] <A-L-P-H-A> must smile at the cute girl server more...
[21:52:08] <A-L-P-H-A> cute 20 year old.
[21:52:13] <les_w> actually...nor running. Got 4000 anyway.
[21:52:18] <A-L-P-H-A> I think she's my little sister's friend.
[21:52:23] <A-L-P-H-A> 2000 per inch.
[21:52:25] <miniMess> nah nah.. that the wifes... she asks for them so i dont steal hers... you cheater... ; (
[21:52:46] <anonimasu> A-L-P-H-A: nice :)
[21:53:27] <miniMess> solid body?? is worth it...
[21:53:31] <A-L-P-H-A> now enough coffee for six cookies.
[21:53:56] <A-L-P-H-A> wait? The server gurl, Dmess' wife, or the 66 bronco? I'm sure all 3.
[21:54:02] <miniMess> shite come get mine.. it feels dirty now...
[21:54:16] <icee> hey all
[21:54:22] <icee> it's pretty sad, but i've never held that much cash.
[21:54:26] <miniMess> pick 2.... and dream
[21:54:42] <icee> held plenty of $10m checks, but never $1000 in cash.
[21:56:02] <miniMess> hmm. we lost 10000 worth of checks cause we hung them on the xmas tree and the furnace blew them away...
[21:56:13] <A-L-P-H-A> bah.
[21:56:39] <miniMess> they were NEVER cashed as the Company dissolved...
[21:57:18] <A-L-P-H-A> miniMess. HAHAHAHHAHAHAHA
[21:57:20] <A-L-P-H-A> lovely.
[21:57:31] <A-L-P-H-A> WTF would you hang checks on the xmas tree?
[21:57:40] <miniMess> so we went in and confiscated equipment and held it ofr ransom with them who had rental contract on the equipment
[21:58:30] <miniMess> dec 19 here's your checks ... were done... stay home..
[21:59:23] <miniMess> none of the chks were any good.. we waited for the bank to open to see if some ones would pas...
[21:59:58] <miniMess> went back and drove equipment thru town....
[22:01:52] <miniMess> called the rental dudes.. said we got your equipment you got a contract.. revock it...
[22:03:11] <miniMess> we rigger nigged a bill of sale... and he sold it on ya.... SEND IN THE HOUNDS
[22:03:32] <anonimasu> miniMess: this stuff gets on a log...
[22:03:58] <miniMess> the got their equipment....
[22:04:58] <miniMess> back eventually.. but the BOSS got stopped like 4 times in a 4 hr trip cause his lic # was on the list...
[22:05:25] <anonimasu> heh
[22:05:31] <miniMess> was already past the 1/2 way point
[22:05:53] <miniMess> we wanted xmas.... and didnt get it
[22:06:51] <miniMess> rental dudes gave us 10000 to spit amongst 12 guys.... to have it back unburnt...
[22:06:59] <miniMess> split
[22:07:49] <anonimasu> ^_^
[22:09:07] <miniMess> miners RULE... we always have a hole to bury a body
[22:17:13] <anonimasu> *yawns*
[22:17:30] <Jacky^> mmhhhhhhh
[22:17:43] <Jacky^> anonimasu: what ??
[22:17:51] <anonimasu> nothing
[22:17:57] <Jacky^> :)
[22:18:12] <Jacky^> i was think bad ...
[22:18:16] <Jacky^> :P
[22:18:23] <Jacky^> thinking
[22:18:43] <Jacky^> les_w:
[22:18:55] <les_w> yes?
[22:19:01] <Jacky^> les_w: is working, I think ..
[22:19:08] <anonimasu> Jacky^: you friend that wanted to build a machine..
[22:19:10] <Jacky^> hey les_w
[22:19:20] <Jacky^> anonimasu: as quit :(
[22:19:52] <anonimasu> Jacky^: how fast does he want to go?
[22:20:17] <Jacky^> anonimasu: i understand he want to build a cnc for aluminium works in 3 min ..
[22:20:17] <anonimasu> Jacky^: and how much $ is he prepared to spend?
[22:20:19] <Jacky^> lol
[22:20:31] <Jacky^> he bought some drivers..
[22:20:39] <Jacky^> wait ..
[22:20:57] <anonimasu> your friend should read up more on machine design before he starts at all
[22:21:40] <Jacky^> http://www.cncitalia.net/articles.php?lng=it&pg=189
[22:21:54] <Jacky^> i don't know if you can see the page
[22:22:05] <anonimasu> so your friend wants a 3 minute cycletime
[22:22:07] <Jacky^> maybe registration is required ..
[22:22:12] <Jacky^> hehehe
[22:22:21] <anonimasu> yep
[22:22:29] <Jacky^> I tried to explain it to him ..
[22:22:32] <Jacky^> :)
[22:23:32] <Jacky^> les_w: later ..
[22:23:42] <Jacky^> if you have a little of time

[22:34:39] <tziOm> hey guys
[22:35:04] <ValarQ> hello and welcome tziOm
[22:35:06] <tziOm> ..wondering.. what version/branch/whatever of etai should I use to test out emc2 cvs?
[22:35:12] <tziOm> rtai
[22:36:41] <ValarQ> i'm using rtai-3.2
[22:36:49] <tziOm> Valar - what kernel?
[22:37:01] <ValarQ> 2.6.10
[22:37:11] <ValarQ> i had some problems with later kernels
[22:37:26] <tziOm> testing out .14 now..
[22:37:50] <ValarQ> ok
[22:38:24] <ValarQ> they modified the schedule code in the later kernels
[22:38:27] <tziOm> will rtai from cvs work you think? is that the 3.2 version? (says magma..=
[22:38:45] <ValarQ> never tried rtai from cvs actually
[22:39:04] <tziOm> this rtai project seems mol dead anyway..
[22:39:19] <ValarQ> what? rtai?
[22:39:35] <tziOm> atleast its a mess
[22:40:00] <tziOm> some code here.. some there .. different webpages, different content, different versions...
[22:40:27] <ValarQ> i only downloaded 3.2 from http://download.gna.org/rtai/stable/v3/
[22:40:35] <ValarQ> worked perfectly for me
[22:41:08] <ValarQ> (perfectly = i have forgotten how much trouble it was)
[22:41:15] <tziOm> 29.may
