SWPadnos: They made the conf artigo kits special (no cables). And no serial cables are available from VIA directly. His suggestion was to buy a pico board from fry's and that will come with the cables.
jepler: Thanks a lot! my wifi is working now... I've been trying for hours
Now for the fun stuff. I'm going to try to make PCBs with EMC and eagle, using: http://unpy.net/cgi-bin/viewcvs.cgi/eagle/ulp/gcode.ulp
Hugomatic: that's great news .. good luck with that ulp
you'll probably have some customizing to do ..

super-duper telephoto lens :)
this one is for TomP: http://www.rcuniverse.com/forum/fb.asp?m=7541729
tomp2, where do you get the motors for your electric bicycles?
eric_U: nice link, thx . i dumped the cyclone crap and got a unit from walmart, cheap and it actually works.
cyclone was the batteries?
or the motors?
cyclone taiwan was the motor lifepo4 batteries chargers pas system, no bike
brushless dc 500W 24V
there is an alternative to a123 called K2, seem to be very good cells
i'll be lookin, the walmart is cheap but sla battereies
i'm thinking d-cell ni-mh
the a123's are so much better
fast charging, high discharge rate with no cell degredation
what's the $/kWh or your preferred units
[03:03:31] <tomp2> http://zeva.com.au/tech/K2/
what's a kWh?
never heard of it
k2 is currently going fore 3.2v * 3200 mAh for $12
that's a temporary price I think, normal price is 2500 mAh * 3.2v for $12
a123 goes for $16.50
but k2 from Oz or Shanghai might add to cost
you can get them from www.battlepack.com
they are about the same pricing as a quality NiMH without the problems
very cool, thx for that link :) ( now wth is a cnc battery? i imagine its for portable cnc's? )
I think it is for memory backup, they are gel-cell bats
[03:10:47] <eric_U> http://www.youtube.com/watch?v=xfVX71YqPuQ
a123 are very dangerous :)
ack.. didn't expect to see him get killed
wow, i hope he's allright, the damn bike looked like it stuck itself right into the side of that van
I'm pretty sure that was just precautionary, and he's ok
now emc folks, that is acceleration
hope he learns his fucking lesson before he does get killed then
1) wear a helmet
2) make sure you have a helmet on
3) let the female assistant do the burnouts
i bought a stupid helmet for my stupid 450W walmart after 1st ride (maybe not so stupid)
burnouts are dumb anyway
gotta have a helmet
burnouts serve a purpose on a drag vehicle
electric tire heater
it is just promotion, no harm to it
bill dube is posting on the killacycle blog, so he must be ok
jmkasunich: thx, an lm318 fixed my board
this beer found its way to my desk
and is forcing me to drink it
* JymmmEMC grabs the bottle from toastydeath and fills it with prune juice
Well, I think I have stiffended up the Z axis stepper all that is possible with this arrangement, or very close to it and I still have about +/- 0.01 slop in the mechanism on stepper movement :-/.

was the RTAI kernel in 8.04 compiled with the kernel source from Ubuntu repo or from vanilla repo?
I'm trying to compile RTAI in Debian Lenny but the kernel source 2.4.24 from Debian repo is incompatible with RTAI. Many files are not in the expected places
fenn_ is now known as fenn
I found that my problem is related with the kernel-headers prepared by make-kpkg. I can compile RTAI modules with kernel-source but not with kernel-headers.
acemi: I had a problem compiling RTAI with the headers generated initially
so I used an additional small patch to ipipe.h
(I used the Ubuntu kernel sources + the ADEOS/IPIPE patch)
hal-linux-2.6.24-x86-2.0-04 I think
acemi: also, make-kpkg doesn't seem to produce sensible packages anymore, Ubuntu uses a custom debian/ infrastructure to build packages
maybe debian does the same .. ?
there is no /arch/x86/Makefile_32 in the headers directory but there is in the compiled kernel directory
therefore I can't compile RTAI module if I didn't compile the kernel source in this machine
alex_joni: after patching the ipipe.h could you compile RTAI modules using kernel-headers?
but the kernel headers produced by make-kpkg weren't good
only the ones I built with "fakeroot debian/rules custom-binary-flavour=rtai"
what is the alternative
(debian/rules is a big script from the Ubuntu kernel source)
maybe try getting the debian kernel sources with: apt-get source linux-image-...
does EMC have any problem with kernel-headers produced with make-kpkg?
I don't know..
but if rtai doesn't compile/install.. then it's useless to try emc2
I want to prepare linux-image and linux-headers and rtai modules deb packages in a machine and than I using this packages to compile EMC in anaother machine
I didn't follow debian way of building kernel packages lately
another question: RTAI is compatible with the standart ADEOS patch?
[10:48:55] <alex_joni> http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official
acemi: usually yes
what RTAI are you trying?
at the moment I would use 3.6.1 (just released a couple days ago), or vulcano CVS
ok, there's a 2.6.24 patch in there.. but I haven't tried it yet
why do you prefere adeos patch?
I don't prefer adeos patch
I used the one from RTAI
I think it's the same
I think there are not same
but not sure
I see Xenomai uses: adeos-ipipe-2.6.24-x86-2.0-07.patch
and for RTAI it is: hal-linux-2.6.24-x86-2.0-07.patch
but they differ a bit (content..)
micges: did you see the patch for blending of arcs for high speed cutting
BigJohnT: can you shortly describe bug that you found ?
jepler did it yesterday, it makes G64Pn work on arcs too
at high speed with short moves lines and arcs were not treated the same so the speeds of each were very different
so if you are doing arc line arc line the speeds change so often that the whole machine shook
now it runs very smooth cutting small arcs/lines at high speeds
wonder how it's impact on my laser after update :)
how fast do you cut?
should smooth out the motion when cutting small arcs/lines
how small ?
I had to play with the P number a bit and play with my cam software to get the smoothest motion
about < 5mm
do you cut out any art work or letters?
then you will see an improvement when cutting letters
the speed will be more consistent as you cut
If you set the P tolerance on G64 you can control how the blending is done
my laser run always in g64 p0.01
alex_joni: does the feed override affect the velocity in EMC?
[11:48:59] <BigJohnT> http://www.cnczone.com/forums/showthread.php?p=457118#post457118
BigJohnT: no, you can neverride past any configured machine constraints (velocity/acceleration)
that's what I thought
cradek_ is now known as cradek
BigJohnT: MAX_FEED_OVERRIDE = 1.2
ok, just when you thought you knew something :)
Stompin' at the Savoy
hey - I know that grapevine
the Ink Spots
I'm having an error with a generated NGC file: "start point too close to probe point". Since my Sherline machine does not have a probe, can I get EMC to ignore it?
have you programmed a G38 code?
Hi cradek... I'm trying to use the gcode.ulp script for eagle
oh, it uses tool length sensing. you will have to take that out and use some other scheme for tool lengths.
cradek: OK, thanks
cradek: can you pull an older verion of the ulp out of your repository? (the older version didn't have tool length)
I'm not sure
should be easy to fix up your copy though.
I would hate to go back because there might be other things fixed.
I'll try to comment out the printfs in the ulp file
you'd have to study the commit messages to figure it out.
Hugomatic: sounds good.
Is the script expecting many tools? I'd figure an endmill for the traces and a drill for the holes, but the script has many of these probes... I wonder why
copper roughing, trace outlines, different drills, board cutout
cradek: this is serious! thanks for the script
hope you get it going!
good night all
a-l-p-h-a: everyone's switched to mach, the channel is closed.
it ain't funny at all
that's funny, I'm about to go swimming
anybody using sheetcam?
it seems to run on linux under wine (at least it installs and starts)... I am looking for some sample parts to play with
okc needs a "no fatties" filter
there should be categories you can click on when you rate someone
that would empty the place in my experience
that was totally the wrong channel
but since i said it
it has been suggested before but the dev team doesn't listen
