heh - lower the gate resistance - the higer the current limit trip.. I don't think I get it. (getting the scope tomorrow)
Imagine that :)
skunkworks, sounds like changing the gate resistance is changing the turn on/off speed and causing you to see a shoot thru current spike
skunkworks, which is tripping the current limit circuit
slow turn on and fast off is usually used to deal with the shoot thru problem when both high and low fets switch together
anyone feeling patient enough to answer/help with a newbie question ? :)
don't ask to ask, just ask
k, well I'm trying to use the live Ubuntu 22 cd ... it loads, but the screen is small in the middle of my screen and the bottom of all dialogs is cut off ... I chose the safe vieo option because stand is even worse
I'm downloading the Drake live CD to try next
is the monitor hooked through a video switchbox, or just a normal cable?
it's a Dell ^00 Laptop

hi stuart, how was your vacation?
I'm coming to terms with going to work tomorrow for a 5 day week - something I haven't done for a while
at least it's not just me.
I got a lot of stuff done. it was a good vacation.
I got less done than I wanted to
caught up with some old friends, fixed a lot of stuff around the house, got some emc code written, got hay for the rest of the winter, etc etc.
no progress on 5i20-fying my step generation (although I did make good progress on generating an as-built wiring diagram for the shoptask - only a year late)
no playing with the Ametek motor (although I did get the encoder and servo drive board)
is that the spindle motor you hope to use?
no, those surplus center servos
the spindle drive project wasn't even on the list for this vacation
I did a lot of hiking with the dog though - time well spent
that's better than servos
and I made fairly good progress on the jig rebuild job
what feed-per-rev do you use for parting?
Vernon is now known as vlmarshall
I'm cutting a thread relief groove, but its the same thing - plunge straight in
very slow speed (25-50)
unfortunately I don't have variable speed
although I could cut the thread OD and shoulder on both parts first, then write another program to do the groove, and change speed for that
are you having trouble, or just nervous before trying?
nervous about chatter
if I screw up either of these parts, I have to back track quite a bit (all the way back to tapping 5/8-5 acme)
I think I'll do the od and shoulder, then I can mdi or jog the plunge cut
I wouldn't jog it
well I guess you can continuous jog slow. I was thinking jog wheel.
I don't have a wheel (yet)
bronze machines almost like brass
except the chips are a lot hotter
any scrap to experiment on?
I have a bit of 1" bar, but I'd have to mess with my setup
I'm doing the OD (shoulder and threads) of the acme nuts, so I have a piece of acme rod in the chuck, that I screw the nut on to
so they have threads inside and out?
yeah, 5/8-5 acme on the inside, 7/8-16 conventional on the outside
back, is there anyway for me to modify the xorg.conf file on the live CD, or will I need to install it?
[02:31:12] <jmkasunich> http://jmkasunich.com/pics/worm03.jpg
on the right
JayC911: you can modify it during a boot, but of course the change will be lost when you shut down
I want to test the chnage before I commit
JayC911: will you eventually want to control a machine with this laptop?
(most laptops make notoriously bad machine controls)
I use Mach3 currently ... works fine ... just wanted to see how Linux plays
can you tell me the steps to chnage the xorg file before it boots? ... I know wherethe file is, but I need to edit it before it's loaded/called
you can't change it before it boots; change after the boot, then restart X
Will EMC run on Xubuntu?
I'm in the same boat, JayC, trying *nix and EMC for the first time.
sure it will
I thought I was gonna love it at first, but I'm getting frustrated.
it will on any modern linux distribution, but dapper/hardy ubuntu based ones will let you use our realtime kernel and packages (saving you a lot of effort)
vlmarshall: what is the issue?
if you want to experience frustration, trying to install emc yourself will provide
xubuntu is unlikely to help there
what kind of machine?
that's almost always a hardware problem
if its a laptop, you've already been told that is probably a bad thing
intel 1.5GHz, 384megs
some hints here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test
laptops have too much extremely low-level crap going on - power management, fan control, etc
ha no laptop, I know better from Mach.
have you tried the SMI module?
it just great latency numbers at forst, around 12-14000, and then spikes around 200000
no, what's that?
do the spikes happen every 64 seconds?
I'm a total linux newbie
sounds like smi
hmm, I saw the mention of the maintenance thing around 64 secs...
[02:58:23] <jmkasunich> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingSMIIssues
ok, it's gone over 64 secs without a spike
still going. nothing else running on it at the moment
do you have any observations about what does make it spike? or is it totally random, out of the blue?
did you read http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting
yes, I've read it, and run the extended latency test
with no overruns
still no spike on that current test
idling, it's fine
what triggers it?
I'm not really sure.
well, there's a crash. I opened a firefox, with no spike, and then added EMC.
you can't run emc and the latency test together
oh yeah, I knew that.
figures it wouldn't spike now
I've been fighting it for 2 days. http://www.cnczone.com/forums/showthread.php?t=70830
update: got the video sorted
vlmarshall: I don't see a problem statement or a question in that thread, but there is a lot of noise - I didn't read it all
yeah sorry about that.
not many emc folks on cnczone. signal-to-noise is much better on our mailing lists.
ok I'll quit bugging y'all until I have more solid facts. It's running fine at the moment.
try running glxgears while the latency test is going
also, move/maximize windows
yeah, I've heard about the lists, but I haven't gotten settled in enough yet to join
yeah I've got 'gears running now too
yeah, I understand, lurking for a while is always a good idea
It's just a little hobby mill, I don't really take it seriously, but this problem has been tough.
I was really happy to see EMC, and it's macro variables.
latency spikes suck. sometimes you just need to use a different machine. but I don't think you have complete enough information yet to give up on this machine.
Yeah I'm not ready to give up yet, but the unfamiliarity was frustrating.
no idea if I could go buy a new vid card and have it work
what video card is it?
I was SURE it was video related

have you tried the vesa video driver?
no, don't know where it is
vlmarshall: in /etc/X11/xorg.conf, put Driver "vesa" in Section "Device"
if it's video, that is very likely to fix it
ha ok I'll try it
Leave the other bits about the ATI card?
what's in your Section "Device"?
Identifier " ATI tech ...radeon rv100 qy [radeon 7000/ve]
yeah leave everything, just add Driver "vesa"
same ATI info is in Section "Screen"
yeah, my laptop is ATI ... can you post the "Screen" section of your xorg.conf
I had to make a few chnages:
I can type it.
one was to use 1024x768 16bit
can't paste between computers :)
what is your DefaultDepth
change to 16
ha I was about to paste it. I saved it to flashdrive
are you editing the xorg.conf with the sudo command?
leave Screen's Device as ATI?
crap no, I opened it with editor.
what is your h and vert refresh?
JayC911: his settings will surely be different from what your laptop needs
it doesn't list them
yeah, it'll be monitor dependent ... but setting the bits down won't do any harm
well, I don't know how to get to it (from Terminal, I suppose), but, I've had no latency spike in all this time.
then cd /etc/X11
sudo gedit xorg.conf
well, now kb stopped responding ... I'll check back later
geez, took me forever to get to the directory.
ok there's several 'Depth's . Just change the Default Depth?
why are you changing depth?
you were going to try Driver "vesa"
There's a subsection for depth 1,4,8,15,16, and 24
yeah I changed that. I guess it was Jay that said to change the depth.
I don't know what Jay is doing. I thought he was doing something on his.
well, latency went up a bunch, but nothing unreasonable so far.
you restarted X after changing to vesa?
haha sorry for being such a newbie.
that's why I haven't touched a *nix.
control-alt-backspace will kill and restart X, or you could reboot.
60Hz refresh rate
that's 85Hz? no way. I can SEE it.
yeah, I'll believe that. ah well, if it fixes the latency...
it's a data point anyway. nothing says you have to leave it this way.
it just spiked.
ran for 10 secs or so, jumped to 243259
did anything just happen? fan start or stop? hard disk spin down or up?
ok started another
hm, yeah, that's an unusable number
seems like it's not video
do you have all power saving, speed scaling, etc turned off in the bios?
no option for scaling, this is a win 2k machine
is this video built in or a card?
that's often trouble. do you have a card you can try?
not that I can find
here let me fax you one to try

ok what about this kernel framebuffer?
did I mention that you should hit enter until done?
I don't know if it was on before.
hahah ok fine :D
that's be a No haha
I have no idea what any of that stuff does
I went through there and tried to decide what to do about each entry, and it didn't change anything as far as I could tell
yay, a gui again
how spoiled we've become.
yeah I'm old.
ok running latency test again
what a pile.
built in video is probably no good
guess I'd better find a card
where are you located?
I'm as close to the geographic center of Pennsylvania as you can get without being in prison
I was sure I had one here but I found everything BUT video.
want a box of modems? haha
I know what you're talking about, I really should dump my collection of obsolete computer parts
yeah but it's COOL to keep an old full-height HD :)
if I bought a new card, can X handle it?
thing is, my wife's bugging me to put a better vid card in THIS machine, and play Left4Dead networked with her. So, I can't justify ANOTHER card... and this thing's onboard too.
she just bought some new card for hers yesterday.
too bad there's no leftover from that.
well, thanks for all the help, I guess I'm off to go digging again
most likely I'll be back :D
I really want to stick with Linux.
dual boot is no problem
you'd think the eagle developers could take a week and put out a 64bit linux version
i actually spoke with the eagle developers about that and they insist there is no reason for them to
i also inquired about a PPC version so i can do my pcb work from my PS3 and there answer to all my questions was that there isnt a significant market for them to develop for any other system
I can see that
the bright side is that if you have all ro the 32 bit libs installed you can run it on a 64 bit ssystem which is what i do
are you running on ubuntu?
i actually run Arch, i hate ubuntu
I kinda hold a grudge against them for basicly "stealing" all the work debian has done over the years
are you trying to get eagle running on a 64bit install of ubuntu?
last time I tried to install debian, I gave up because the setup was so brain-dead
oh i see
I had gotten sick of fedora/red hat, but I only have so much time
well since im not an ubuntu guy myself all i can say is that you should be abse to install the ia32 libs and eagle should run other than that I dont know all of the ubuntu specifics
I have yet to figure out why these distributions don't steal each other's installers, what's the point of open source?
I guess I need to figure out how to install the 32 bit libraries
some of them do steal and that is exactly what ubuntu has done, they stole everything debian has done and gave nothing back which is not in the open source spirit
im assuming you have root access
try apt-get install ia32-libs as the root user
do you know how to use apt-get from the command line?
that should install everything you need then good luck with getting eagle install
it only installed 6 libs
the libX ... were not installed
will eagle install now?
it did, thanks
that's what I get for reading error messages
yep when in doubt consult man pages
which man page for that?
i dont know of one off the top of my head
but at least you have it working now
surprised that isn't mentioned on the ubuntu forums
problem is, my experience with using yum is down the tubes
it probably is somewhere but i wouldnt know where, but if you get a chance i do recommend trying out debian or what is best is that i recommend everyone build their own linux system from scratch at one point or anther
will apt-get is a thousand times better than yum so you made a great choice
I've heard that, but I'm not sure I believe it
trust me it is. debian has bar none the best package managment system (which ubuntu stole) it is the largest software repo, the only down side is if you want a slimmed down system some of the packages are a little bloated
Is the main advantage the repos?
yes and the easy system upgrades
system upgrade would be nice, I had to get a new computer because I didn't want to upgrade my fedora version :)
and if you are using debian rather than ubuntu, they put their software through alot of testing before they publish it so it in among the most secure
was you wanting to upgrade the fedora install or the ubuntu install?
hhmm its been many moons since i used redhat so im afraid i wouldnt be much help there
no prob, I need to back it up and wipe the hard drive and start w/ a new install
that's the fedora way
lol, reminds me of the rebooting windows days
they have upgrades, and a while back they tried an experiment upgrading with yum
but my version preceded that
fragalot is now known as Guest33641
well you wont have that problem with debian or ubuntu
well im off to bed nite all
thanks for the help, good night
How can you tell when you're out of invisible ink?
you never run out
you'd think so
If your car could travel at the speed of light, would your headlights work?
Guest33641 is now known as fragalot
alex_joni: Assuming you turned them on BEFORE moving, yes.
alex_joni: ...and that you never have any turns to make =)
well.. I'm not so sure
that might be true for the first 100m or so..
no turning at the speed of light as there are some silly mass problems alleged
alex_joni: Well, if you turn on your lights for (lets say) 10 seconds before you start moving and that you can accelerate from o to 186,000 MPS in 0 seconds, You'ld have at least 1.8 million miles of light before you ran out =)
* archivist hugs the inverse square law
re light from a point source
Fine, 500,000 miles
but who's counting =)
more like 1/2 a mile
g'day all and Happy New Year
morning / afternoon all
archivist: how do you get from 2 million miles to 1/4 mile?
JymmmEMC: light from a headlight doesn't travel 500.000 miles
JymmmEMC, learn the inverse square law and you will know the light will be too dim
but you will be moving too
the new light coming out of the headlights travels at the same speed as you
so it won't appear in front of you :)
pjm__, battles the same law with microwaves
but the light doesn't stay at the car even standing still, it projects
at what velocity?
nope, only one
speed of light :)
if you move the light source at the exact same speed, it won't project anymore
Lucas named their headlights projectors at the turn of the 20th century
interesting Q "If your car could travel at the speed of light, would your headlights work?"
my useless fact for this century
we need to merge archivist with wikipedia
alex_joni: Yeah? think about that the next time you use your headlights standing still... light is not at the bumper, it's at leat 1/8 mile down the road too
because it got there
does it depend on where the observer is? if they are also travelling at the speed of light then since its relative, the lights will work?
pjm__: the observer is supposed to be inside the car
* archivist doesnt believe all this relativity stuff
alex_joni: Right, but it doesn't STOP being project from the headlamp
of course it doesn't
but the lamp is standing still
pjm__: the obvious answer is "of course they still work :D"
yeah thats what I thought
you will NEVER catch up to the light that's 1/8 mile down the road
the second question is .. do they shine light in front of you?
JymmmEMC: but it only travels for 1/8 mile
of course they do
relative to the observer
JymmmEMC: maybe switching it before starting to move will work
light will leave the lamp at 2X light speed
alex_joni: That's what I said
pjm__: no it won't
pjm__: you cant go fast than the speed of light
ah under the current laws of physics perhaps not
whats light travelling "in"
archivist: you suck
Im not a black hole
archivist: maybe a black hole of info =)
archivist: small buckets
I cannot believe the wave AND photon
ok question,, earth is travelling in orbit at about 107,218 km/h, and light speed is about 299792.458Km / sec. If I shine a laser in the same direction as Earths orbit, how fast would the 'speed of light' be to an observer not on earth?
if wave then there IS an aether
pjm__: you don't have such a question
such a laser
alex_joni: I do, and it has a cool shark too!
this laser exists in the world not governed by the current laws of physics
ok not lazer but say a microwave transmitter
laser i mean
I guess at the speed of light
plus the speed of the earths transit through space?
the speed perceived by you will be less though
the other way around
light travels at the speed of light
not relative to some ref. frame
I think :)
Ok, if a laser pointer is a pure source of light at a given wavelength. Why is it that when you point it at the wall it has a "specilly" appearance to it?
ok if u have a ball and can throw it at 20mph, and throw it forward from a moving car that goes 20mph, a static observer would see the ball go 40mph?
(simple laser pointer)
where as the car driver would see it go forward at 20mph, does this not apply (in a simple way) to light speed + earths transit speed
i know F all about this as u can probably tell ;-)
oh, and I'm serious too.
owever, as speeds increase this rule becomes less accurate. Two spaceships approaching each other, each traveling at 90% the speed of light relative to some third observer, would not measure each other as approaching at 90% + 90% = 180% the speed of light; instead they each measure the other as approaching at slightly less than 99.5% the speed of light.
that assumed the speed of light is the maximum possible speed though?
because of http://en.wikipedia.org/wiki/Velocity-addition_formula
If one of the velocities for the above formula (or both) are c, the final result is c, as is expected if the speed of light is the same in all reference frames. Another important result is that this formula always returns a value which is less than c whenever v1 and v2 are less than c: this shows that no acceleration in any frame of reference can cause one to exceed the speed of light with respect to another observer. Thus c acts as a speed l
can we get stephen hawking in here???
he probably needs a CNC milling machine for something
I am serious about this... Ok, if a laser pointer is a pure source of light at a given wavelength. Why is it that when you point it at the wall it has a "specilly" appearance to it?

damn, I can never remember what the trailing slash in rsync does
I want to rsync a folder and all it's contents to a remote server
/usr/bin/rsync -avzrtlue 'ssh -p 1234' /sourcedir firstname.lastname@example.org:/destdir is what I have here for updating my www over rsync over ssh
that's a push, right?
yeah it pushes from my local server here over inet to a remote box
i've got ssh setup with private keys etc
I've been using this as a PULL:
rsync --verbose --progress --stats --compress --recursive --times --perms --links email@example.com:/home/user/ /home/user/public_html/blah/
but I need to PUSH this time
no keys, no rsyncd
would I just reverse the source and destination?
archivist: short question for you
I have a wristwatch, how would I go on and sand the glass on it.. it's pretty scratched
just replace normally
not sure I'm able to ;)
well its a cheap item at a watchmakers (should be)
depends on make etc
only the waterproof glasses have a special fitting and some Rolex
is it a real glass or plastic
alex_joni: you can try buffing it out
sound slike real glass
it says water resistant on the bottom 100Ft
some have a Saphire "glass"
alex_joni: I used a bench grinder and converted it to a buffer. bought a few cotton buffing wells and some compound
[13:01:17] <alex_joni> http://www.epinions.com/Calvin_Klein_K3212_30_Wrist_Watch
alex_joni: I would suggest you test using a piece of glass, as it take practice
leather Strap, Mineral Crystal, Swiss Quartz, 30 Meters Water resistan
to retain waterproof use a watchmaker who knows what he is doing to replace
pjm__: Confirmed that going from PULL to PUSH is just a simply reverseing the source/destination
ok great, is it working?
archivist: no real need for waterproof
pjm__: it's done =)
but I wouldn't want to replace it
Mineral Crystal == glass
archivist: I don't think he's going to take it apart
what JymmmEMC said :)
cool, i use rsync for my nightly backup of my pine email directories here
I never bother polishing watch glasses here (we do clocks mainly)
pjm__: I usually pull to backup one of our vhosts, just needed to PUSH to a different server this time
well good that its working
rsync is under used imho, yet its an excellent tool
I under use it to the maximum possible
ther's also rdiff-backup == rsync + version control
Though, I do need to figure out how to grab symlinks in certain areas, and to follow symlinks in others
wow that was fast

i just wanted to say i appreciate what you guys have done with packaging of rtai stuff for ubuntu
and i had a question about building on top of it
i need to upgrade to an rtai version that is newer than rtai 3.6 because of the python support
the latest we packaged is 3.6.1
but i guess i need to know how the linux-image package, rtai-modules, etc. packages were put together
I would do it this way:
get the rtai source from http://www.linuxcnc.org/hardy/dists/hardy/base/source/rtai_3.6.1-linuxcnc.4.tar.gz
get the 3.6.2 rtai from rtai.org (or whatever version you need)
well i need the latest one
3.6.2 or -cv
get the debian/ folder from the 3.6.1 source you got from linuxcnc
put it in the 3.6.2 dir
there's also a build script in the topdir
use dch to change the version
it's +x, so it's easy to find
should work then to build a new package
install with sudo dpkg -i
so i shouldn't need to rebuild another linux-image?
if so, that's awesome
the whole thing should take about 10 mins tops
including the downloads ;)
* bigcx2 starts his timer
i did a checkout of vulcano
i'm updating the changelog with dch
but i can't find what version that corresponds to : aka 3.6.?
in the rtai source anywhere
doesn't matter that much
just curious really
the version in the changelog isn't from rtai.org
it's the numbering we used for linuxcnc.org
if you got a CVS checkout, then there's no real version number
yea but it at least starts correctly
if you download 3.6.2 or 3.6-cv then that's your version number
right...but vulcano as i understand it is the "stable" branch
I'm not sure why "dch" likes to append "ubuntu" to the version number on ubuntu, but it does
you can use 3.6.3-mumble.6
i'm kinda wondering what that corresponds to
bigcx2: it doesn't really correspond to anything
the last version was 3.6.1-linuxcnc.4
Our package is based on 3.6.1, comes from linuxcnc, and there may have been 3 packages before that one. 3.6.1-linuxcnc.4
when you used dch it tried to increase the version number
it did that by adding ubuntu1 at the end (it figured it's not an ubuntu official package, and now you're ubuntizing it)
so it's some "smart" branding dch does
no i know i've done packaging before
probably a dch -i would be more appropriate
seemed odd to me at first too
i was jw about the rtai versioning that's all :)
if you all need help or anything maintaining stuff i'd def. help
bigcx2: thanks for the offer
if you want to help drop an email to firstname.lastname@example.org (after subscribing ;)
and state in what areas you can help out..
[13:30:55] <bigcx2> http://www.linuxcnc.org/hardy/dists/hardy/base/source/rtai_3.6.1-linuxcnc.4.tar.gz
does that correspond to apt-get source rtai-modules
from your repo
(fwiw, 3.6.cv as a debian package version is newer than 3.6.<digit>; if you're packaging 3.6-cv maybe that's the version number you want to start with)
at least for i386 :)
bigcx2: but apt-get source rtai-modules-2.6.24-16-rtai is a lot more to type :D
right right lol
bigcx2: we also have amd64 packages
(if you're packaging something from the cvs that's expected to become 3.7, then call it something like 3.7~cvsYYYYMMDD; that version is lower than 3.7.0 in deiban numbering)
i like that
alex_joni: yea i actually didn't know that until i ran apt-mirror on the linuxcnc archive on a 64-bit machine, and it didn't capture the 32-bit stuff!!!
unfortunately, I've only had a chance to try the 64-bit stuff on one machine, and it's unstable there (while regular ubuntu is quite stable) so I don't think our 64-bit stuff is ready for production use yet :(

hi ray, long time no chat
It has been a bit slow with the latest stuff from firefox. That flash or whatever thing.
I keep watching. Been busy of late.
I never figured out if there was a pattern to the crashes on my machine (amd, dual-core) but if I left the machine on it'd eventually just hang
Mine is a single core. That might do it.
I don't remember if I ever tried booting with only one cpu ..
(there must be a commandline arg for it)
model name: AMD Athlon(tm) 64 Processor 3000+
this box Im on is a dual AMD
mine is at 118 days, firefox needs regular kills though
archivist: running the linuxcnc.org realtime kernels?
[Global Notice] Hi all, I've added a new module to our services installation, that may be of interest to those of you with enforce enabled. It may also cause some adverse interactions with auto-identify scripts, however. Please see http://blog.freenode.net/?p=164
for more information. Thank you for using freenode and have a great day!
archivist, It took me a while to find that firefox problem.
it has the generic kernel in mine
the regular ubuntu kernels are just fine on my machine as well (at least as long as I don't run vmware :-P)
Ah. I've got jeff's rtai running here.
rayh, I just reboot firefox when it slows or fails to play vids
Yep. When it acts up, everything slows way down. Like 2 second delays.
2 to 30sec or more delays
Then it sounds like firefox plays the same on the stock and the rtai kernels.
takes a few minutes to time out when stopping it
there is some bug in the latest couple of versions of flash
some vid playing freeze after a while, playing only 2-5 seconds, then it pauses
I kill off npviewer when it starts to act up.
I must try that next time
[Global Notice] Hi all, terribly sorry to bother you *again* but regardless of how much hairdye I go through, I can't get away from being blonde. Needless to say, my previous global resulted in inadvertedly ddosing the machine hosting the blog and website. Please try again later and for now, call me Homer and watch me Doh!
yeah, on my laptop the 32-bit flash9 would stop working after awhile until I restarted firefox. the native flash10 doesn't do that, but in certain games it flickers annoyingly
(64-bit, dual core laptop; different machine from the one I tried to run realtime on)

Sounds like they have some work to do on firefox.
when it's the proprietary plugin that crashes, I blame the proprietary software
Oh. I didn't think about npviewer being proprietary. That would do it.
I get the same buggy behaviour on doze too
so it's surely not ff related
Probably written by someone paid under the table by that other software company.
bigcx2: I see it worked..
bigcx2: why bc i stopped asking questions
alex_joni: why bc i stopped asking questions
alex_joni: yes that is a good assumption :)
alex_joni: thank you
i also joined the mailing list, i'll send out an email here shortly
rayh: I don't think npviewer is proroprietary (it's GPL2 or later), but the flash plugin is (and on 64-bit systems with the 32-bit plugin, flash executes in address space of the npviewer program)
bigcx2: rtai mailing list ;)
It seems to invade all by itself rather than when I want to view something. (Cause I usually don't)
isn't the internet wonderful
you can use firefox extensions like flashblock or noscript to restrict flash only to places you want to view it (usually by clicking on the rectangle on the page where the plugin goes)
(noscript is a bit of overkill for that, as it breaks all dynamic websites by default)
I like flashblock - 99% of flash stuff is crap
I recently discovered there are people that obsess over flashlights
um, I have a flashlight I like
it's in my pocket
is there a 12-step program?
there is and OCD person for every possible item I bet

obvious if you think about it
anyways, it seems like a nice way to find out which drive it is :)
with as many drives as they had, they would get hoarse
did he really mean 500 msec? that seems like an amazingly long time
typical disk latency
actually, if it weren't for the 500 ms latency windows injects on some disk accesses, you could probably do pretty decent real-time on windows
i love yelling at the drive :)
I used to punch my monitor fairly often
I gave up when i realized that it didn't matter to the monitor
stupid monitor, doesnt even know its not liked ;)
I've heard that is a common failure mode for lcd's
bashing things to test for dry joints yes, but anger no
we had a grad student break a laptop screen, he said he fell asleep and hit his head on it
having see-through windows is not really that great of an effect
what do you see when you see through your desktop?

that's a good idea
I forgot about that

yep cant wait, and all of my steppers will be here toaday as well
SWPadnos on here has a working config for the 540 - you should ping him when you get a chance.
ping reply before send error
you have a config for the 540?
yes. I need to check with Mariss on some timing questions, but the config should work
I had a problem with the spindle output, but it turned out to be the board
planning to visit JymmmEMC ?
great can i get a copy? that will save me alot of time with setup
not sure, and he's a bit north of LA anyway :)
it will be good to have a second test of it before it gets checked into EMC2 and put on the Gecko website ;)
cool, just DCC it to me here or you can email it to email@example.com
ok, will do
I may even write some instructions or something :)

archivist: we had -35C not far from here last night
we are supposed to be getting -10
only -25F I guess..
hmm.. units gives a different result
we had -19°C here this morning
well.. at least it's supposed to be cold in sweden :)
here -26C only
LawrenceG: that is the odd issue.. increasing the gate resistance (which should slow things down) cause the effective current limit to be lower.
I am using diodes in parallel with the resistors for fast turn off.
Should be fun to look at it with the scope tonight.. ;)
skunkworks, is there any chance the diodes are in backwards?
I tripple checked them :)

i have one problem with emc2.2.8 is possible help
i have one problem with emc2.2.8 is possible help
flexmotioncnc: go ahead and ask your question
i have install and compile emc2.2.8 on linux debia etch with rai patch
i have one problem
the proble is :
when i start the motion the one axis the position count the axis increment or decrement
but sometime the counter position axis stop the counter , but the axis move normaly.After 1 second the conter increas normali for stop after 4 second ec.. what is the problem
you understand the my problem
no, not really
is this while jogging, using MDI commands, or running an NC program?
are you testing with a bare HAL setup?
are you using G-code that runs multiple axes, but only have one motor hooked up (so this motor stops while others that aren't connected would be in motion)
the problem is present in manual, in mdi and auto mode.when i start the emc2 the software the counter position axis is ok for 10 or 15 minuts, after time , the counter posizion stop the increses when i move the axis or single axis.
the counter being the onscreen DRO?
yes the position axis on screen
is the GUI responsive in general - does it redraw relatively often, can you resize the AXIS window and have it update quickly?
yes the response the gui is normaly, i use the video card integrated on board.is possible the problem is the low performante the video card on board?
well, my line of thought was that the realtime code seems to be working, since the motors keep moving. The GUI is userspace code though, so it could get swapped out to disk, held up by some other program, etc.
ok . i change the video card for ceck this problem.The problem is present after i move the window or open the menu ecc...What is the video card on agp is ok for linux debian letch 4.05?
maybe your opengl is broken
whith resolve the problem?
for resolve this problem i change the card o reinstall opengl library?
cradek, maybe a very long gcode file problem? and axis redraw is slow?
you should test some other opengl applications
if opengl is not working, you will have to troubleshoot; I cannot tell you how to fix it
If it is an OpenGl problem then maybe one of the other GUIs might work. For instance neither tkemc or xemc use opengl.
possibly. but it's only a guess. so many things can be wrong with a kernel+rtai+emc build.
True but it would rule out AXIS
The problem is present in tkemc and xemc and axis inteface
ok, so it is probably not a graphics problem then.
The test latency rtai is minlat -1200 nsecond and the maxlat 3510 nanosecond.
does the problem occur with any configuration file, or only with a specific configuration file? any messages shown on the terminal where you start emc, or the last 10-20 lines printed by the command "dmesg" after the problem occurs, might provide us helpful information.
ok, the lathe is inside, so it's time for breakfast. bbl
Worked up an appetite?
i have compile rtai kernel with procedure on emc wiki debian rtai install and the compile is ok no error
no message in terminal when the problem is on
the axis move correctly
does it happen with any configuration file? for instance, if you choose the sample configuration file sim/tkemc.ini, does it happen?
i use the mesa 5i20 card , tomorro i see in simulation mode
the position feedback shown on the screen has to travel like this: realtime => task => user interface
if the problem occurs in all configuration files, then you need to see if you can figure out where the position feedback is getting lost, for instance by attaching to milltask with a debugger or adding debugging print statements to it.
the function that copies data from realtime to task is src/emc/motion/usrmotintf.cc:usrmotReadEmcmotStatus.
the function in task that prepares the data to be seen by the user interface is src/emc/task/taskintf.cc:emcTrajUpdate
ok , i thing the code is ok and the compile not return the error in fuction.not is the software problem i thing the problem is hardare
that's what trying sim/tkemc.ini will help you determine. If it happens there, the problem is software (because your 5i20 card, motors and encoders aren't used at all). otherwise, it indicates that there's a problem with your configuration file or with your hardware.
ok thenks i see the problem and tommorro i speack for you in irc.Thanks for all
come back soon
