03cradek * 10emc2/tcl/tkemc.tcl: seems to fix it on ubuntu (the missing $f was a bug everywhere)
excuse me :)
anyone tried microwaving wood to season it?
fenn dont leave it in too long or will catch on fire =)
nah once the waters boiled out it cant get any hotter
if you cook it too fast it might crack though
oh you said wood, I thought you meant pot =)
03cradek * 10emc2/src/Makefile: oops
03jepler * 10emc2/src/ (7 files in 4 dirs): allow emc to work when CVS keyword substitution hasn't taken place
is there such a thing as a switched-mode speaker amp?
guess i should at least try to look before asking dumb questions
if you turn a transistor halfway on (like in a linear amp) a lot of power is dissipated unnecessarily
instead you turn it on and off quickly to simulate an analog signal
fsk seems to be something different
I know that are push-pull amps, and many other kinds as well, but les would know more about that than I. Class A amps, Class B amps, Class AB amps

tpub is pretty cool
no idea, just googled and that came up.
Ah, much better --> http://www.tpub.com/content/neets/14180/index.htm
its basically OCR'd military training manuals
didnt see anything in there about switching amps
i guess this is commonly referred to as a 'digital amplifier"
Hi anonimasu, G'Night anonimasu
can you believe that it's already been 1/12 of a year
went by pretty quickly for me
another 5.5 months, and I'll be even older.
A-L-P-H-A: happy ;)
I am aging. :(
Jacky^afk is now known as Jacky^
what is this? http://commons.wikimedia.org/wiki/Image:Taumel_142_b.png
looks like an rc helicopter thingamabob
thats strange thing ..
[12:38:37] <Jacky^> http://www.beppegrillo.it/eng/2006/01/lets_black_out_china.html#comments
double yay, and triple yay :D
I finally managed to enable DMA here :D
yeah, but until now it always caused errors
hdparm -d1 /dev/hdc
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
is the cdrom /dev/hdc ?
well, that's a bad paste
it was hda
a 250GB WD drive
but it was a kernel problem
booting a 2.4 non-SMP worked
only this 2.6.8-SMP didn't work
I had to manually specify piix to load on startup
oh.. smp, never tried it ..
now it works
Jacky^: you said something about hdparm the other day, where does it store configs?
nm, found it
I've a script in /etc/init.d/hdparm
its not recognized by rcconf
it was installed by hdparm package
/etc/hdparm.conf should be ok to customize it
HDIO_SET_DMA failed: Operation not permitted, wonder if is a kernel bug ..
its seem the kernel is compiles without DMA support
asked in #debian ..
14:38 < tralala> Jacky^: you need to load the ide drivers for your chipset before the ide-disk module
14:39 < tralala> Jacky^: you can do that by generating a new initrd image
mkinitrd should help
oh, so I need a new initrd?
I think so
ok, I added piix to /etc/modules, and that was better
at least on last reboot, now it won't work again :(
I'll try a new initrd image
hrmm.. seems only /etc/hdparm.conf doesn't work
alex_joni: wich kernel ?
I rebooted without /etc/hdparm.conf, and now running hdparm -c1 -d1 /dev/hda works OK
Linux xeon 2.6.8-2-686-smp #1 SMP Tue Aug 16 12:08:30 UTC 2005 i686 GNU/Linux
im using 2.6.14-2-686
I didn't find it..
well not going to use sid on this machine
I might consider testing, but definately not unstable
it's a vital machine (will be)
any luck with mkinitrd ?
alex_joni: its a long story ..
tring to solve
I heard mkinitrd cna't work with 2.6.14 kernel
yaird should be ok
its a bug
now tryng ..
any special commands?
if you switch to initramfs-tools this would work first time, but that requires you to install udev, you can work (maybe) around this bug in yaird by reading the bug report and following the instructions in there (possibly substituting your ide chipset for whichever they are fixing in the bug)
15:50 < dpkg> #345374:N[yaird] yaird: Cannot turn DMA support for ide devices on; Fri, 30 Dec 2005 23:33:01 UTC
I tried to add sis5513 (my chipset) in /etc/mkinitrd/modules and rebuild with mkinitrd -o /boot/initrd.img-2.6.14-2-686 but didnt work
lets try yaird
yaird? what's that?
[15:08:29] <Jacky^> http://www.google.it/search?hl=it&q=yaird+bug+345374&btnG=Cerca+con+Google&meta=
there's some interesting discussion about that bug
any clear conclusion?
was tryng to install the new kernel 2.6.15
it's strange.. because it does work for me
with piix added to /etc/modules
Configuro linux-image-2.6.15-1-686 (2.6.15-3) ...
Finding valid ramdisk creators.
Using mkinitrd.yaird to build the ramdisk.
yaird error: could not open /usr/lib/yaird/conf/Templates.cfg (fatal)
mkinitrd.yaird failed to create initrd image.
Failed to create initrd image.
dpkg: errore processando linux-image-2.6.15-1-686 (--configure): il sottoprocesso post-installation script ha restituito un codice di errore 9
Sono occorsi degli errori processando: linux-image-2.6.15-1-686
but not with using /etc/hdparm.conf
E: Sub-process /usr/bin/dpkg returned an error code (1)
guess that's why it's unstable
hdparm doesnt matter..
did you apt-get install yaird?
yeah, already installed
I do not have udev
Jacky^: if I switch off any hdparm stuff from /etc/hdparm.conf, and issue them manually after the boot it WORKS
just not at boot-time
ok, lets see if I can get yaird working ..
Jacky^: I just rebooted, and it works right
without anything in /etc/hdparm.conf
so I'll leave it like that for now
Im now running 2.6.15 kernel. fixed Yaird issue copyng Template.cfg , but didnt work yet ..
I think initramfs-tools should solve
now tring that
like I said.. I'll wait till debian releases a new kernel
dma should work out of the box.
im going to try
alex_joni: it work now
nice, what did you do?
I installed 2.6.15-1-686 kernel, nut it should work also with other, I was having the same issue with the 2.6.14
udev and initramfs-tools
are now installed
I removed 2.6.15-1-686 kernel-image and reinstalled
it has created the correct links and image
any special commands you used?
I tried to manually create the initrd by using yaird before, but it didint work
after installed initramfs-tools and reinstall the kernel-image it work
so basicly 'apt-get install udev initramfs-tools'
then initramfs ?
apt-get install kernel-image ?
dunno what youre using
kernel-image, as it's 2.6.8
you was having the dma issue with that ?
anyway should be correct, yes
hahaha nice flash file :)
as I sayd it didnt work after I tried to manually build the /boot/initrd.img-2.6.15-1-686 with yaird, it goes in Kernel panic
it worked after I did apt-get remove kernel reinstall kernel..
and, its ok, I'm able to manually set dma on off using hdparm now
btw, it is always on at boot time
but havent tried old kernel images i've
mmm going to check
its ok, it also work for others kernel
* Jacky^ came back to 2.6.15
wonder when ati will release the drivers for xorg 7
SWPadnos: what ? :)
almost as funny as Matrox releasing a new Linux driver
I found an howto here http://wiki.archlinux.org/index.php/ATI_Radeon_8.20.8_and_Xorg_7
the drvers are supposed to be compatible between XOrg and XFree86
but cant see anything about xorg 7 in the ati website ..
xorg 6.8 its ok.. but I'm using xorg 7
708 frames in 5.0 seconds = 141.464 FPS
its slow ..
well, ATI has been pretty bad about drivers for the last few years, I wouldn't hold my breath
the GATOS drivers may be OK, but they're not as well accelerated
that is slow. I get between 11000 and 12000 on my NVidia card
I have to run vmware and 3D cad too :/
as do I
someone sayd got a good results using Radeon instead of fglrx driver
I doubt it ..
I lost track some time ago. my only ATI card is a Radeon 8500DV
256 mb ?
64 or 138
I don't remember
the mine is 256
64M, but it's with the remote and the video breakout box (plus firewire and stuff)
I didn't think the 8500 could handle that much
I use tvtime to watch tv on a corner of my desktop
I actually bought that card so I could make a MythTV machine in the theater
never got there though, and now the SFF computers are so much spiffier for that
there's even a dual opteron smal form factor machine O_O
hmmm - maybe I can afford just one more "little" computer ;)
this one http://www.newegg.com/Product/Product.asp?Item=N82E16856101809
a whole lot of power in a small package
but then again, a fanless computer would be better in that situation (also, I'm just noticing that this has no optical audio inputs or outputs)
maybe Ive seen something like that produced by apple in some shop in naples, weeks ago
not sure ..
the mac mini is quite similar
the yours seems a good choice
I think the mac mini starts in the $500 range, but once you add enough stuff to make it really useful, you could have that little dual opteron supercomputer
much better :)
yep - $699 for a 1.42GHz PPC, plus monitor, keyboard, mouse (and that's only 80G HD + 512M RAM)
closer to $1000 when you add in that stugg, and upgrate to 100G / 1G
take a look at what I had to send to Idroid expert to get it understand I was doing anything right and the sound follower board on my robot is defective..
[16:59:26] <Jacky^> http://digilander.libero.it/jackydgl0/idroid.jpg
after I send 3 email, they was asking again if I used the correct cable.. withou read any quoted text on the email !
after they have seen the photo, they sayd, well, you should ask to our call center the sostitution of the board.. O_O
if they don't have a form letter for it, they cant help you.
they are doing a disaster sending the parts to the peoples: defective boards, wrong cables, defective gears, someone (readed in the forum)had some battery explosion too
If you look at the spot, they say: you just need a screwdriver to build your robot !
bill20r3: you can explain as better as you can, but some people believe only when see with his eyes
in nov I had to call Dell because my lcd's powersupply was failing, took me 30mins to convince them that my lcd actually used an external supply
had to send the tech to an ebay auction for the same part and say "I NEED THAT THING!"
lousy outsourced tech support.

neat DIY 3d scanner.
but I've about 20 links on bookmarks like that
[17:13:02] <Jacky^> http://www.splinescan.co.uk/
and so on .. :(
* fenn wants to make a DIY MRI scanner
* Jacky^ decided to buy it :(
splinescan is such a horrible piece of junnk
its seems to me like to look at the moon with a binocle, not with a telescopy
High quality od lens, camera, laser, should make the difference
that culd mean 20-30K Euro
what does parallax have to do with laser scanning?
how it work ?
on what depend accurancy ?
the shape of the line traced by the laser
and the ability of the software to pick out only that line
yes, I agree ..
routine to process the image arent a secret for what I know
laser scanners dont like radiosity
maybe if you had a low-energy neutron beam... :0
do you use a camera to capture the image right ?
looking at the difference beetwen my sony cybershot and the k4ts nikon there's a sea of difference
in only E. 300 more
talking about quality image
supposedly digital cameras for photometrics are ungodly expensive
Does anyone know a *nix gcode simulator?
simulator? like to show toolpaths?
axis is pretty good in sim mode
dont ask me how to do sim mode
To sinulate the toolpath threw the worked piece
fenn: I think a good 3D scanner use special optical lens, and circuits
AXIS started as a standalone g-code viewer, it should not be difficult to make it work that way again
patches happily accepted
using a 'normal' camera is a cheap way
* chinamill is away: eating
hey les_w :P
any progress with you work ?
just trying to work out some safer control logic for the machine
It seems there is no way around doing a tool change on a hot spindle
in other words
mmm .. yeah
VFD is powered up but commanded in off state
les_w: would a crappy homemade PWM motor driver amp suffice for a subwoofer amp?
ha...yeah fenn I would work
and sound bad
how much power do you want?
do you need to tune the output filters for a specific speaker or for a specific frequency?
think 500W would be good
well just so you don't hear the pwm frequency
easiest way is to make it well above 10 kHz
that ought to be like 20khz anyway
power dissipation starts going up
right.. i was reading an article that said that you had to fiddle with filters based on output impedance
up to 80 hz I have about 700 watts per channel depending on how you rate it
check this out: http://www.positron.org/projects/basscannon/
understand very very few single drivere can handle over 500 watts for any length of time
kinda reminds me of the SRL pulsejets
ridiculous, based on out-of-phase pipes, and LOUD
wave radio on steroids
I use a mccauley 15 with a qes of about .3 and fs of 28 in a 12 cubic foot box
It does the job. One on each side.
let's see max cont output at 25 hz for the pair is....
just need to find a giant whelk
* fenn just wanted to say "whelk"
about 125 db I meter.
but the boxes are big.
if you are content with say 105 db....the boxes can be pretty small
you are missing the point
with the same LF response.
my first sub: http://digilander.libero.it/jackydgl0/ub_simsub.jpeg
the point is to have a BASS CANNON!
18 years ago ! was a monster :D
i do like the idea of not wasting power radiated into the speaker cabinet
ah...looks like a bandpass box jacky
of couse, it wasnt use any xover :P
fenn, well gain bandwidth product, size, and efficiency are tied together
the resonant pipes are high efficiency very low bandwidth
but yes you can get into the 110 dba/1 watt with a quarter wave pipe
mine (fourth order high pass) is enough for me.
IT breaks things.
I don't turn it up much though.
I just did a bunch of stuff in the music room.
Must put midrange absorbing on one wall
and am commissioning a mural to be painted on it
hi jymm...well we talked about some layouts
a HUGE pot leaf?
yeah that sort of thing...
well you got naked women, now you need either thousands of rounds of ammunition or "boose" of some sort, right jymmm?
Oh... what about transition thru decades?
hendrix, clapton, pot, paisley, etc
jymmm hmmm good idea...
les_w: aleady seen this: http://www.geocities.com/royal_device/customita3.htm
music room... so 1800, 1900s 2000, etc
wonder how it pump ..
Well, I just retired some old amps, bought new, and put in some SEAS midrange vertical arrays.
they sound very smooth
I can servo control the low end speaker cones....accelerometer feedback to amps....
but it does not sond right
Yuga was working around a nice sub too, if I remeber well
Most music is mixed on speakers having some second and third order harmonic distortion.....
without it there the music often sounds unbalanced
Yes I have been working with yuga on a very high power PWM powered speaker
He wants to make speakers for a living
[18:03:36] <Jacky^> http://www.geocities.com/royal_device/salaGIF.GIF
that's the complete plain
good lord why not just use hydraulics and shake the floor mechanically
I have much more in the low end that I can really use I guess
better than not enough I suppose
les_w: seen the plain ?
all that to get 1 people heard music ? O_O
sitting inside horn
Well, I got a very good result with the changes lately...midrange is very important
very smooth and lifelike
there the critical frequency side :(
I Still have 16 of the SEAS drivers left....bought a whole carton if you recall
will use that for other stuff
they each have 100w cont voice coils....400w peak.
so they can almost do a hand clap....120 dba.
oh well...hmmm back to hot spindle.....
if that thing comes on while changing bits....
it would be really bad
I would prefer to remove power from the vfd while tool changing
But the documentation says that often removing power will quicky destroy the drive caps
les_w: use a relay on the motor lines
Wanted to alex, but drive docs advise against that too...
how about placing a shunt resistor insteadof the motor
if it opened during running for some reason....the drive is fried
resistor might work
would need some inductance too
4 kva gulp
you get the point
I called some people and most change tools with vfd on
Just seems dangerous to me
* Jymmm concurs
oh....made a manual speed dial on panel/ emc dac/parport selector switch too
I think I will mostly use manual
les_w: whats the risk of change the tool with vfd on ? shock ?
or damge it ?
so I have an on/off and 0-24000 rpm on the panel.
Jacky I think the risk is having a 4 kw spindle turn on with a loose tool or while you have wrenches on it
shoulda got the atc spindle
It was $4000 more...but yeah, your'e right probably
anyway another machine will have one.
i just repeat what other people tell me
covered wagon with two horses trotting down the street
with two giant confederate flags
yea we kicked the amish out of indiana.. guess they ended up in GA
on the wagon
wonder what the occasion is
I'm afraid I'm not much of a confederate
* chinamill is back
How is emc2 coming along?
bleh...let's see now....please check out my logic.....
les_w "You're KungFu is no good!"
no switches or contacts between drive and motor per vfd manual
soft estop disables amps only
hard estop disables amps, shorts servos to braking resistors, and removes power to vfd
power interruption causes hard estop...
as do hard limit switches
Jacky^ is now known as Jacky^afk
sounds sane to me
vfd must be powered the move servos...but motor does not have to turn
Just going through some simple FMEA for various component failures
glitching the VFD on input remains the worst
So waht is the status of emc2? Close to release?
glitching VFD off during cutting is second worst
chinamill: pretty close
I think 2 wire control to contacts or opto at the vfd is safest
For glitching an off command to the vfd... I can program the logic on it so either off or failure of the device or power sends a fault
than have an override to cut air or jog
spindle rotation stopping during a cut would cost thousands of dollars in damage
but you want to do it for jogs and verify
I am trying to rewire this so the workers can safely learn to use it
alex_joni: If I'm not mistaken you where working on a escavator some time ago, how is it coming along?
aj: then it must have been someone else here, I do not remember
ok then :)
oh that was anonimasu
hmm turned on the news during lunch break....someone went "postal" in california
what is with post office workers?
they've gone postal perhapse? lol
maybe they don't get enough christmas cards
or too many
just cooked some experimental lunch here (low on groceries)
It came out looking like kingon food.
I hate grocery shopping
les_w it's still crawling on the plate?
I broke up some angel hair pasta into shot pieces and threw in gravy mix
looks like it could crawl
Jacky^afk is now known as Jacky^
programming some open collector outputs here
ok fault is sent if drive is stopped for any reason including an off command
that function can be overridden by a phisical switch
but additionally an actual drive electrical fault will go to hard estop despite switch position
trying to failsafe any glitch phenomina on logic inputs
Failsafe is turning into more buttons to push I think
Hmmm...is that gonna work? Operator has more to learn, but it's harder to issue commands that cause safety concerns?
kinda wish I had a logic level signal when motion is commanded.
03jepler * 10emc2/scripts/realtime.in: Prefer the rtapi.conf next to scripts/realtime so that RIP setups work even when there's an installed version
03jepler * 10emc2/src/rtapi/ (rtai_rtapi.c rtai_ulapi.c): now that the right copy of the rtapi is being loaded, the version check is safe again (but the version is always 0 when $Version$ is not substituted, so it is of limited value)

4:45 pm here
quittin time but no commute
I love it
after spending hundreds of thousands of miles commuting
I only commute to the music room.
and the liquor store =)
or is that on automatic daily dleivery?
I do have a bit of a commute to do though soon. Back and forth to chicago.
well shit.. you said you hate grocery shopping... auto delivery just makes senses.
safeway.com and all that
They asked me today if I had picked a nice car yet for travelling
I haven't bought one yet.
Guess Lexus GS 300 is it.
Not my favorite
but quiet and reliable
Sadly AUDI, MB, BMW have scared me off due to reliability horror stories.
Will keep the 325i though for just around town though.
how are you?
I am fine...just finishing my work day
I look document for hospital
from car accident?
jacky showed me a picture
no car I'm fall
sister of Jacky^
accident for car!
Is jacky's sister ok?
but not car...
[22:08:49] <Jacky^> http://digilander.libero.it/jackydgl0/incidente/index.html
* Jacky^ working.. :D
we have a name for that here...it's called "totaled"
it means the car is finished
there's nothing to repair
what was that? FIAT? aLPHA?
just to thanks some saint for saved they
was a ford station wagon
I have a ford truck.
if you recall we talked abiut this crash
no airbags are open ..
So now your sister is fine?
modern cars have 6 airbags
les_w: yeah, my sister is ok now
yes I guess the one I will buy has that
they have been very lucky
I think my truck and car now have only one
New cars have side airbags I guess
abs and airbags can save the life
If cars had a steel tubing space frame roll cage like the cnc machines we design....
less would get hurt in car crashes
oh the logger is on...we have to talk about emc
I like emc.
jacky, k4ts, I will go to the music room now
have a nice evening
you too ;)
