giacus. :P no
it's working now
les_w... stop entertaining guys... go find some women to entertain.:) hehe
yeeeeh! gaim irc
I played a diana Krall cut for anna...
anna is K4TS here
I was teasing her last night.
I think A-L-P-H-A-2 is using wpa encryption to talk now :P
she still has her new dog right giacus?
yeah, a puppy
I only have chickens and cat.
[00:27:57] <giacus> http://www.giacus.org/files/kyra.png
A-L-P-H-A-2: btw, I can confirm ..
there were few other woman on th music room :P
oh... les_w was telling me about that room...
[00:29:28] <A-L-P-H-A> https://wiki.ubuntu.com/BinaryDriverHowto/ATI#head-5ead174a0b3294527486cd4d71ded66b40003f25
A-L-P-H-A: I use drivers from stanchina website
that's not a rabbit shirt... it's tonights dinner menu!
[00:30:31] <giacus> http://xoomer.alice.it/flavio.stanchina/debian/fglrx-installer.html
Jymmm: I like that shirt :P
what is that stuff in the glass? looks like ink
A-L-P-H-A: but I don't know it they're ubuntu compatible .. check for it before
les_w: red wine
marelboro and a glass of ink?
an excellent wine maded in campania
about 12 E. bottle I think
I also like Lancer from portougal
it should be all around the world
did the dog get wine and marlboro?
haha, not yet ..
giacus I was just playing =)
les_w did you see my earlier question about a clear coat that doens't absorb stain?
no, but shellac spit coat works well
how do I tell what version of X I'm using?
or a vinyl sealer
Hmmm, never heard of a vinyal sealer, will google
spitting shellac bugs huh?
it's just ethylene vinyl acetate random copolimer in an aromatic solvent
doens't sound as durable as PU
it is a thermoplastic
as is shellac
is it? I thought shellac was just bug juice
yeah...it's bug juice...but it's a plastic too
old phonograph records were made of it
It's kinda strange to me... PU absribs stain but is more durable than the stuff that won't.
It's all about surface energy
surface density I understand, even understand surface tension, but never heard of surface energy
surface energy is surface tension for solids
[00:41:51] <Jymmm> http://en.wikipedia.org/wiki/Surface_energy
yes that seems a good article
Hey! you tricked me into learning something about physics! (and nothing explodes or goes boom either!)
so now you know
and knowing is half the battle
The real american HERO!
A-L-P-H-A dont make me hurt you
I have a kit to measure surface energy. It has calibrated fluids, and you measure contact angle.
example of high surface energy: very clean metal
example of low surface energy: teflon or a waxed car
pane of glass?
clean glass can have pretty high energy
ok, I'm gonna have to read this article about 15 times then.
water will sheet over a high energy surface
but you just said a waxed car is low energy
we measure it in spring units like newtons/meter
and the water beads off of that
the water has more afinity for itself than it does for the low energy surface
oh oh i misunderstood when you said SHEET
I was tinking bead
so you get it
yeah, but doesn't surface energy realte somehow to density too?
It relates usually to dangling bonds
only very clean surfaces have high energy
so sandpaper would have low surface energy
like freshly cleaned metal
water sheets rather than beads
ok, so where is "surface energy" a factor most (industry wise)?
the coatings industry
learn somethign new every day =)
just remember surface energy and surface tension are the same units
hopefully I'll never have to use either =)
If a liquid sheets out on a surface that surface has a higher surface energy than the liquid's surface tension
ah, ok, I get it now.
liquid A could bead on glass, where liquid B could sheet on the same material.
what happens when something gets absorbed/mixed together?
just more complicated
The word "energy" is what threw me a curve.
but it is energy
because it's a spring
yeah, but not in terms I am accustom to... (electrical, gas, thermal, etc)
It makes sense now, just was never exposed to such things.
you need to make one of those little boats with the tiny slot where you put a drop of oil
and it runs along
was it oil or soap?
probably either one
soap reduces surface tension
ah, I was thinking of when I put soap into a grease pan, and hte grease goes "EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEK" and runs away
well soaps and detergents chemically bind on oils on one end and water on the other
but there was some science demonstration where you make a little boat with a hole and slot in it
you put a drop of soap or something on it
and it runs away
Yeah, I'll have to make a wax paper boat and tryit out =)
But in general surfaces don't want to be there. It takes energy to cut stuff up to make surfaces. Things would rather be in a big ball with the least surface to vbolume ratio. That's the lowest enegy state.
ah, cool. Maybe I shouldn't have been getting stoned in high school afterall =)
what's the glgears or something to test openGL?
ran a few amps though my drive - mosfets seem only start to get warm at 3+ amps.
no heat sink yet
The little motors I have had some sort of encoder on the back - with a lm339 chip on it. Can't get a decent signal out of it. not a good square wave. Need to make a schematic from the circut board to try to figure it out.
lm 339 is not the fastest comparator in the world...but ought to make a pretty good square wave in an encoder
it has 4 wires coming out of it - red black white and blue. I ass-umed that red and black are suppy. the blue to ground and white to ground are putting out a saw tooth wave at the most. at .3 volts.
when the motor is spinning.
could it be differential?
I use differential in all my encoders
otherwise you would need only one wire for the signal...not two
could be - I am just going to have to look at the circuit board better.
this was out of an old line printer if I remember right.
four wires couldn't be differential
I am not up on my encoders :)
differential is two wires for each phase
just going to have to make a schematic - and look it over.
one goes plus the other minus on each pulse.
so you would need six at least.
2 for power - 4 for 2 balanced signals?
what kind of HELP?
Im doing some simple test - can I explain them to you?
1st ill tell you where im at then ill tell you what im doing.
I am a reletive newbe - but ask away and someone will help
where'd everyone go?
I was scrolled up. duh.
I settup ubuntu with emc2 and modified an ini file and a hal file to run my machine - I have a step and direction driven 3 axis mill - I start emc2 w. tkemc and can move my machine around in manual just fine - so I moved my zaxis to a point where I read 10" between the table and the bottom of the spindle - then I tell the machine in mdi to go 1" up and it only goes like 0.3"
its not a axis scale thing because I know I set those up right.
is z the only axis that does this?
I havent checked the others yet? should I do that first?
and is it exactly .3 - and .3 every time you try to move an inch?
no its not consistent - its different every time.
I can't get ubuntu to get openGL to do hardware acceleration. :(
im just useing a tapemeasure to get a feel for if the macine is working properly
have you run this machine before with other software or is this the first time it has moved?
what kind of hardware - dives - motors?
I have run it with TurboCNC - and it was very accurate and I even cut some parts with it when TurboCNC had control of it.
sounds like your velocity or acceleration is wrong
Hardware = Cambel breakout board, 3 Gecko320's, DC servo's with encoders. Gecko320's drive the DCservo's based on step and direction signeals from the parrallel port that are isolated through the breakout board.
if you jog slowly does it maintain position?
yes - a slow jog does maintain. hold on letme double check...
yup - at 2" inches a minute it looks like what it's coordnate readouts are giveing are correct
then your scale is right
I guess you should experiment with velocity and acceleration
do you know how to use www.pastebin.com?
what should I change them to?
sure put your ini on pastebin
ok - doing it
you don't know what max velocity or acceleration you used when it was working right?
I would have to reboot to TurboCNC and check - here http://pastebin.com/754917
which axis are we working on
1.2inch/sec is 72ipm, which is pretty fast, did it go that fast?
actually I would have to change to the hardrive with FreeDos and TurboCNC to do that. we are working on the Z axis. no 72 inches a minute gave me an error
actually - it seemed like I could go that fast but the coordinate readouts where wrong to what the machine actually did -
I just tried it - I get a following error when joging at 72 inches a minute
AT 50 INCHES A MINUTE IT LOOKS OK IN JOG MODE - BUT IN MDI MODE STARTING AT Z0 AND PROGRAMING TO GO TO Z1.0 IS WAY!! OFF
then set your max velocity to .833 which is 50ipm in inch/sec
OK - DOING
and stop yelling
SORRY i LIKE TO BE IN CAPS LOCK WHEN TYPEING MDI CODES. sorry :-)
my net connection is only staying up a few minutes at a time now, I might disappear
I need to get the cable company out here again
I changed line 130 to 0.833 - Im restarting emc and testing again - wait
yay! that looks much better!
yay, simple problem, simple solution
mdi is consistant with the coordinate readouts now
you'll probably have to work on the other axes too
I changed line 130: which was in the trajectory area - doesn't that change it for all axis?
yes I think so
but you should set it in the axis sections too
often you want the traj limit higher than the axis limits because if your axes can move at 50 you can make some moves faster than 50 (diagonal ones)
ok - one thing, if my X and Y are 10000 steps per inch but my z is 5000 per inch, should I change them all to 0.833
that depends on what velocities your machine can handle
you'll have to experiment
it's fine for the different axes to be set differently
I'm off to bed, goodnight
one last question
is emc2 set to incremental or absolute arcs by default
[04:17:12] <cradek> http://www.isd.mel.nist.gov/personnel/kramer/pubs/RS274NGC_3.web/RS274NGC_33a.html#1002442
here is the documentation for the arc command
you can specify the center by radius or by incremental distance from the arc's start point (ijk)
thankyou - gnite
[11:23:09] <giacus> http://www.giacus.org/files/intro_beta_3.avi
update, please suggest about it
yeah, the code
sound bad ?
it would be 12-15 minuts in total
since the origin until today
who know the exactly date matt contacted the nist ?
can't find it around
lunch .. later
fenn: the title for the clip would be "The EMC2 Code"
it would be nice to include some nice machining clip and interview to the developers and protagonists
quite hard to get it ..
I could publish the cinelerra project if anyone can help about it
I think it could take a long time to be done ..
but would be nice :)
giacus: should have said something 3 weeks ago
right, but it wasn't on my mind at that time
now tryng to get all possible resources
another hard thing are the audio comments
giacus: tried that file today
it wasn't there anymore
for now I'll use subtitles, an audio track could be alway added
hi .. just came back from lunch
and another thing I'd like to try is to capture few video of google heart zooming from sat to the nist location and others..
dunno if that could be used as Free or any (c) problem occour
giacus: is that movie still there?
[12:42:36] <giacus> http://www.giacus.org/files/intro_beta_3.avi
hmm.. upgrading from breezy to dapper isn't quite the way to go :)
[ 41.903512] Unable to handle kernel NULL pointer dereference at virtual address 00000000
until now, I just tried to capture a a google heart zooming on jepler location, isnt bad at all :)
it could be also possible to use few images instead of a entire video as in this flash clip :
looks good so far
[12:46:46] <giacus> http://web.tiscali.it/fspaghetti/
but you need to work on the text :)
I can't ..
ok, can I help then?
need ypur help :D
get a better idea
put it in pastebin or somewhere where I can edit
heh.. my current dapper? actually starts in about 7 seconds or less
lol.. it oopses and doesn't load any more sh*t
but then the X server comes up, and it basicly works :)
what an annoying website
agreed on the website..
[12:53:24] <giacus> http://pastebin.com/755421
what website spaghetti ?
I'm just looking at the idea of zooming from sat, not oher
[12:56:17] <alex_joni> http://pastebin.com/755428
ok, updating cinelerra files ..
I'll show it to you when ready
rendering and converting ..
[13:12:05] <giacus> http://www.giacus.org/files/intro_beta_4.avi
have to fix dissolve time for some text yet ..
yeah, only a bit..
I would start with 'The History' first
maybe some stuff about NISt
yeah, of course
and research & such
just after a short and impressive intro
I meant before The Code
that's would be the title
the sound is quite 'aggressive' in that point
yeah.. I know..
a shot of great effect is needed
* alex_joni needs to listen to the tune again ;)
it's been a while
K4ts: on my laptop running xp ..
like an horror movie :(
giacus: I really meant 'imagine a world' not 'image a world';)
I was doubts about it ..
ok, so text intro 00:00 -> 00:00:25
some pictures (maybe fast flashing by) examples and all kinds of stuff: 00:25 -> 01:02
starting to explain (what is emc2, what can it do (only general ideas)) 01:02 -> 01:38
updated, same url as before
some history (NIST & co ) 01:38 -> 02:50
then the people (pictures from meetings & developers) 02:50 -> 03:57
i'd like to include some shot from linuxcnc website, Axis and others
I can capture it directly from screen
what its really needed is some video machining stuff
then the descriptions in more detail 03:57 -> 05:50 (emc2, machine control, example machines, GUI's, remote control, hardware control, hardware abstraction layer, interconection, classicladder, kinematics, scara & puma robots, threading lathe, milling, cutting, etc)
one could be the cradek lathe
I have a small video from someone here the other day
let me put it somewhere
make the 'free' last a bit longer
instead of 'The Code' I would put 'The Enhanced Machine Controller v2'
yeah, its ok
I taked the idea about the title from The Linux Code videoclip
the yours seems to be more appropriate
alex_joni: looks like the mosfets start to get warm over 4+ amps. (no heatsink yet)
skunkworks: there are no curves on datasheet about it ?
I was hoping to close the loop last night but the encoder on the back of my motor did not seem to work correctly. had a lm339 comaritor in it - I am just going to have to draw up a circuit.
could be normal, maybe
giacus: home made drive :)
yeah, but not mosfet
looking at the curves of mosfet you should get some clue I guess
I am happy with it :)
giacus: which patch did you use for 2.6.15 ?
the one from adeos?
latest numberd 1.3 I guess
let me check ..
Hi. I am trying to install EMC on Ubuntu. But it basicly says Could not load 'rtapi'.
d3dib: can you describe what you already did?
I did just everything explained here http://www.linuxcnc.org/index.php?option=com_content&task=view&id=21&Itemid=4&lang=en
that's what I used
d3dib: did you reboot?
alex_joni, i did reboot with the specific kernel
ok, so that works.. and you get that error when you try to start emc2?
what version of Ubuntu did you install?
* alex_joni hopes it's not 6.06 ..
yes.. i use ubuntu 6.06
argh.. that's only 2 days old ;) our packages are meant primarly for 5.10..
ok.. can you issue a command?
issue a command?
open a terminal, and run a command
sudo mknod -m 666 /dev/rtai_shm c 10 254
alex_joni, btw. i have used dapper already 2 months without problems :)
i ran the command
/dev/rtai_shm is there.. should i reboot with the magma kernel and try running emc again?
you probably will need to run the command just before you run emc
it will get lost after rebooting because of udev
try to get in here with the kernel booted
the problem is that i cannot access the network with that kernel
but i reboot now.. get back later
maybe we should add a strong note of caution that the packages are for breezy, not dapper
that would be wise for now
d3dib: hello again
alex_joni, hi again. Thanks for the mknod trick for Ubuntu 6.06. I could launch emc2 succesfully with that
that's good to hear.. we need to work on that
d3dib: I tried using the breezy kernel on a dapper last night, but it didn't work for me (maybe you were lucky:)
alex_joni, i could run the kernel without problems
ok, maybe I was out of luck :)
only problem seems to be the missing network connection. or is it meant to be that way?
no, what network card?
i actually have three. 2 of them bonded together.
I got it to boot at one point, but very quickly in the boot process I got an oops (kernel oops), and then it jumped over to X, without loading a lot of stuff
they are of different make. but none appear on the list
maybe that's true for you too..
did it start up faster then usually? (the list in the beginning with the Ubuntu in the middle of the screen , and messages on the bottom)
yes, maybe i didnot watch carefully
try rebooting to it, and watch 'dmesg'
you should see some stuff in there
also I noticed that syslog & maybe other services don't get started
yes, sound device was also missing
after 2 weeks we will test more that on ubuntu 6.06
i will report more when we get hands on it with the real stuff
alex_joni, thank you so far.
Have to go now. Se you later.
* alex_joni yawns
and compiles a new kernel while doing that
any one used FREMILL at all??
free mill sucked in my catia stl and made code in unde 2 minutes my first try thru
any luck with the movie?
was away for a shopping :)
planning to cook fish this evening
well, thinking about the move too
I have to capture some short clip of kernel compiling, rtai running and others
I want to ask if les_w can shot a shot video of his machine running
the mine is too poor :)
I can just shot at the bit cutting, hidding the rest, lol
dmessier: attempting to create a short documentary video about emc
any good idea is welcome :)
[17:50:11] <giacus> http://www.giacus.org/files/intro_beta_4.avi
get machine video off the nicest machine .. and lots of screen shot stuff...
we could use some public domain clip
but I'd prefer to use our own video
so far so good.. ; )
giacus: how did you record the boot message?
alex_joni: to be onest, I first tried vnc2swf.py
that didint work for libs issues & pymedia
after that , tried istanbul
didint work on my wm, need gnome
at the end, I succesful got it by vmware running linux
heh.. sounds like a bit of trouble :)
I actually have debian testing on a virtual machine
I use that to test kernel compilation too ;P
also have a real machine running the 2.6.16 magma, celeron 800
but there can't capture the screen
so, using vmware and converting the video
the problem instad is to capture from google heart ..
I tried with the camera with poor results
the focus going to be bad zooming the map
a realtime screen recorder would be ok, maybe
but google heart eat all the cpu and ram :/
what's google heart?? im an idiot i guess
its a nice app
google for it
I can show you my house, wait ..
dmessier: sounds like google earth
i can see the roof of our cottage 400 miles north of me
[18:01:51] <alex_joni> http://www.google.com/heart/heart01.html
[18:02:16] <giacus> http://www.giacus.org/files/sat1.jpg
my house is in the center of that map
[18:02:47] <giacus> http://www.giacus.org/files/sat2.jpg
here with different zoom
that's google earth fwiw
I found jepler house :)
I'd like to find the NIST
should not be hard at all
alex_joni: another way could be to manually save any shot and then use them tu build a small clip
gov agencies and military instalations are black spots on google earth
but .. dozen of jpeg to save :(
[18:05:56] <alex_joni> http://maps.google.com/?ll=45.74039,21.21122&spn=0.001711,0.003626&t=k&om=1
<- this is me ;)
I have a stupid question -
I was trying to get the hang of Tkemc last night and I cant figure out how to set zeros - where do I set G54 55 56 etc - I right clicked on the readouts and zeroed them after edgefinding, I even ran one program and cut some chips, but at the end of the program(M2) it lost the zeros and I couldnt get them back.
why did they reset.
because you didn't zero the axes
you set some offsets
there is a Home button on the right
wholepair: in tkemc, the offsets you set by right-clicking the readouts are called "g92 offsets". When you run a g-code program and it ends, the g92 offsets are no longer applied.
dmessier HATEs g92....
they are old school
oh - so a simple fix would be to recall a G92 at the begining of my program. - or - if I call G54 and then use the Home button alex_joni refered to that will put the axis offsets in the workoffset table.
wholepair: you can set g5x offsets in tkemc by choosing Scripts > Set_Coordinates, but I'm not familiar with how to use this screen.
great - how do you set zeros and run multiple parts?
I don't know. I use AXIS (which sets a g54 offset when you use the "Offset" button) and typically I set it manually for each part I make.
script . set_coords should work..
ok, I think your answers will help, I will go out to the shop and learn some more.
come back and ask more questions anytime.
peein' rain here today
so no flying takin' place
dmessier... it's monsoon!
hey.. fun ehhh
my sons are playing soccer all day...
yeah... i was in that for a little bit... walking in and our of stores.
ahhh haaa on them...
my driver door is wet now thanks to the drive thru at BK
LOL... i left my window open all night... my van is soaked
was it raining last night?
it was pouring around noon

dmessier, hear about the terrorists being jailed in Pickering?
something like 19 people arrested.

any fuel oil found>??
Targets that I can think of... Ottawa, Toronto, Pickering, Darlington.
P & D scare ME the most...
i'm in the middle...
anyone here want to talk about servodrives ?
etla: not really ;)
well how about documenting the emcmot and emcio interfaces ? ;)
aiee.. not even that ;)
etla: Sure your welcome to document them =)
nice video there explaining what ubuntu means
got the rain again !
going out for a drink ;P
btw.. there's a new ubuntu flavour I spotted today.. Xubuntu
featuring XFCE4 a lightweight WM
"sudo apt-get xubuntu-desktop" should convert to it
That sounds kinda nice... sitting on the patio of a country villa overlooking the water, with a gnetle breeze blowing
sipping a cool drink
sigh ... just when you think it cant get any worse ...
you know I do this software thing for the Swiss guys
we just did a big series of auctions in Washington, yeah, the Java stuff
I couldnt go .. so I sent one of my swiss colleagues ... and we have a really big series of auctions in geneva this week
well .. the guy who went was really really busy, infact was so overworked hes had some sort of seizure ...
so you need to go there?
this is bad. bad bad bad.
a seizure is always bad
