had servo current on the storage scope today.
well, I suspect when we turned off the misblending we turned off blending altogether.
no blending is not as bad a horrible misblending
not totally positive about this though.
with the correct accel / decel algorithms its the same
well I can switch from g61 to g64 and look at the scope.
that will tell.
dont blend the motion control.... control the accel/decel of a constant mass
well we have control with max>accel and amp current limiting
I am not sure of this. Something is way screwed up still though.
oh, it's something in tp/tc.c
s-curve at the trajectory level is basically a rewrite
it feels lead/lag related...
could be, but I don't think so.
lead is d term
lag is I term
tried opening "in pos'n" zove to see if blends are better...??
I just se nasty, nasty spikes
not as bad as before though
bad enough to trash any HSM
IF...your monitoring too SMALL a window.. its NEVER where it should be... it'll be jerky and stutter on the servo v
I am looking at fairly large windows...scope horizintal is about 1 second
but the drives accel / decel should monitor the ZONE it needs to accel/decel
servo tuning is good...1/2 cycle overshoot
have some excitation of x gantry rocking mode complex conjugate pole pair
drive is suffering from data starvation...
not a software issue except for the lack of a notch filter in the pid
no, I don't thinkk so. I think it is math errors in the code.
math errors should should repeat.. run the same prog and record and compare...
ron a large circle to see if its on all axes??
then try a small
yes. We have a special program to do just that. it is a slow helix using x,y, and z.
I did the math and paul coded it.
it does large and small
up a cone in smaller faster arcs
yes basically that is exactly what it does
We should post the code somewhere.
normal projection ON the cone
it's a simple c program that writes g code.
where were yo 15 yrs ago
its a mold runner test piece too
15 years...hm let me think....I was a director of reserch and development at a corporate division.
manager of research and development
must get the silly titles right!
and would NOT have given me the time of day.. i rest my case.. i got her done... ; )
s/research/finding the right beer/
actually dmess...I might have hired you!
damn... always laye for everything.... ; (
but i SOMETIMES get laid
huh? what's that?
depends on th $$$ situation... LOL
dmess I could take that to a whole new level...
after two ex wives, I know that is true.
and im still sleepin with my wife... NOT the chick on the corner that looks pretty hot after a few pops
I am in rural georgia. It would take an awful lot of pops to make the girls look good here.
like in the "beer is good for you" thing
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
you want a friend list you hack me
but your BAD.... ; )
dmess: stop confusing me
nah nah... your it...
* Jymmm reads about planers and jointers
it's all about having a plan before the party.
otherwise bad stuff happens.
03rayhenry * 10emc2/configs/mazak_rf.hal: added a few more sigs
03rayhenry * 10emc2/configs/mazak_rf.clp: start of tool arms
planers and jointers...hmmm
we have those.
Never touched either before. Just difficult to find tin wood here, so thought i might try the pallet thing.
some pallets have very nice wood
most do not
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 =)
wood for signs?
japanese packing crates are good
we use walnut. It's cheap, stable and carves nicely
err english walnut
dmess wouldn't know it if I saw it =)
juglans nigra...american walnit
uh...what is that identify thing? hads to reboot.
/ns identify <password>
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??
I have not done abc....need to mess with it. I hear it has some problems
or x add pullses y negate afew...
step pulses? don't know. We do full servo.
i just think it needs to be ANOTHER type of input ... possibly and input axis??
but what you are talking about is basically feedforward
but with servo could i pull on it and have IT listen to me... and react on the other axis
bt i may want to slow it all down
dmess, that is a matrix feedforward...where x depend on y or similar
yes.. x is program.. y is operator input...
well, PID is basically dumb. It only knows errors. Feedforward knows the dynamics of a machine
emc has zeroth, first, and second order feedforward
thats zero.. ; (
or .. wait... its 1
output=position* feedforward term
what is used a lot is accel feedforward....
if the structure lags due to accel forces... feedforward compensates
paragliding/hang-gliding simulator.... of baro recorded flights...
like if a fast car pressed you back in your seat...
les_w: what would you think about staritng a TP ducumentation project?
feedforward would move the seat up a little so you are the same distance from the steering wheel
that sort of thing
anders: sounds great. Might be kinda like a "unified theory" project though
I think the emc tp is structure more complicated than superstring theory
I understand why that is though.
[Global Notice] Hi all. We're experiencing problems with cogent transit and we're rearranging the servers to compensate. Apologies for the inconvenience.
any thoughts on the flying sim idea... doable??

mmm.. dumpstered sushi
m/e eats $200 worth of sushi
you mean dayold?
they throw it out the next day at 11:30
Here in civilization... the sushi places if they close at 9pm... they clear out the stuff at 8pm at discount prices.
that's nice of them
better than wasting the food.
so they just sell it off cheaper.
cause if someone gets food poisoning, they get shut down.
so better to break even, then loose money, or worse.
even if the person gets the sushi out of their dumpster??
they didn't sell it to you.
maybe good catfood.
but not human consumption.
yeah i feed it to my dog too
what happens if they forgot to put it in the fridge... and a human consums it.
what happens if you dog gets the runs?
i'm pretty sure most dogs can handle rotten fish pretty well
[02:54:43] <A-L-P-H-A> http://www.flashfunpages.com/couple.swf
rotten sushi-> dog food engineering?
A-L-P-H-A thats funny
some girl sent it to me.
if she only knew....
designer claps 2 times.. ( just like james brown) and instant part...
fast sintering machines ;)
or something like that..
no mind control metal removal.... it ALL in your head...
miniMess: lay off the crack ^_^
no chemicals alter your synapsys and that screws wit the plc ...
and other i/o devices
my wife just showed me mittens for the small dog .... im dying here...
there ARE 4
someone SHOOT ME...
there should be 5 - one for the tail
it never STOPS it would shed it
PUG... i call her frank... her name is Pearl
hey for those that didn't see this earlier.
there's a sweater tooo.... bring THE gun i shoot myself...
sexist as hell. but funny. http://www.flashfunpages.com/couple.swf
thats a keeper... wife just pounded off....
you had the dogs and cats in shoes too.. didnt you..??
HEHE... I'll buy her a tim hortons coffee...
you're only 20 minutes away. hehehe
she'll meet you.. you're close..

heh. what happens if she's bad?
i'll stop now
the rings on you right hand cause if you us you left it feels like someone elas is doing it...
ha just sold something. Got a two inch thick stack'0 hundreds in my pocket. And no one to spend it on.Too bad.
les_w: spend it on me ;)
les_w... I'm your new bitch.
what'd you sell?
how much is two inch thick stack of hundreds?
alpha me and a chum are thinking of doing an amture nite at yuk-yuks in ajax.... can you round up a croud...
Dude, majority of my friends are now in Scar, Toronto. Why would they want to go Ajax?
sold the farm??
nah...just an old car.
sold the ex-wifes skeletol remains.
for shits and giggles...??
a first year '66 bronco sport
wives nvolved i take it
nice machine.. in good shape...4000
FUCK! stupid timmies. There's coffee grounds in my coffe.
must smile at the cute girl server more...
cute 20 year old.
actually...nor running. Got 4000 anyway.
I think she's my little sister's friend.
2000 per inch.
nah nah.. that the wifes... she asks for them so i dont steal hers... you cheater... ; (
A-L-P-H-A: nice :)
solid body?? is worth it...
now enough coffee for six cookies.
wait? The server gurl, Dmess' wife, or the 66 bronco? I'm sure all 3.
shite come get mine.. it feels dirty now...
it's pretty sad, but i've never held that much cash.
pick 2.... and dream
held plenty of $10m checks, but never $1000 in cash.
hmm. we lost 10000 worth of checks cause we hung them on the xmas tree and the furnace blew them away...
they were NEVER cashed as the Company dissolved...
WTF would you hang checks on the xmas tree?
so we went in and confiscated equipment and held it ofr ransom with them who had rental contract on the equipment
dec 19 here's your checks ... were done... stay home..
none of the chks were any good.. we waited for the bank to open to see if some ones would pas...
went back and drove equipment thru town....
called the rental dudes.. said we got your equipment you got a contract.. revock it...
we rigger nigged a bill of sale... and he sold it on ya.... SEND IN THE HOUNDS
miniMess: this stuff gets on a log...
the got their equipment....
back eventually.. but the BOSS got stopped like 4 times in a 4 hr trip cause his lic # was on the list...
was already past the 1/2 way point
we wanted xmas.... and didnt get it
rental dudes gave us 10000 to spit amongst 12 guys.... to have it back unburnt...
miners RULE... we always have a hole to bury a body
anonimasu: what ??
i was think bad ...
les_w: is working, I think ..
Jacky^: you friend that wanted to build a machine..
anonimasu: as quit :(
Jacky^: how fast does he want to go?
anonimasu: i understand he want to build a cnc for aluminium works in 3 min ..
Jacky^: and how much $ is he prepared to spend?
he bought some drivers..
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
i don't know if you can see the page
so your friend wants a 3 minute cycletime
maybe registration is required ..
I tried to explain it to him ..
les_w: later ..
if you have a little of time
hm, what kind of parts?
how much material would he like to remove?
I would like to examine bcs motors
anonimasu: no idea ...
he just join to the channel
is it for running production?
and ask me for plain
he's have a shop motors
bikes motors i think
he will find a good solution for his machine ;)
hello and welcome tziOm
..wondering.. what version/branch/whatever of etai should I use to test out emc2 cvs?
i'm using rtai-3.2
Valar - what kernel?
i had some problems with later kernels
testing out .14 now..
they modified the schedule code in the later kernels
will rtai from cvs work you think? is that the 3.2 version? (says magma..=
never tried rtai from cvs actually
this rtai project seems mol dead anyway..
atleast its a mess
some code here.. some there .. different webpages, different content, different versions...
i only downloaded 3.2 from http://download.gna.org/rtai/stable/v3/
worked perfectly for me
(perfectly = i have forgotten how much trouble it was)
hey ValarQ whatever happened with crapahalic? and can I see the source code?
i want a 3 minute machine too.... i'll cough up 1 M... but it has to do any of my parts in 3 minutes
* fenn contents himself with crapplication for the time being
