cvs gone. it served us well.
how fast is that, anyway?
I'm not even sure what it means
if startrek is some sort of definition - some log of the speed of light.
Hey have you guys considered getting into the Ubuntu universe repository? Or setting up a 3rd party apt-get repository?
Or just a PPA?
Anything rather than distributing binaries really
The main value is that in Karmic it'll be _much_ easier to add a PPA repo
you should email them El_Matarife
EMC is meant to run on any Linux system, we just happen to package it for Ubuntu
SWPadnos: I mean proper packages in a ppa that you can give updates for and everything
* YokoZar is an Ubuntu dev
ok. I'm not too savvy about launchpad vs PPA's, etc.
as you can see :)
launchpad ppa = personal package archive. Basically you make a team for your project, upload your source package there, and it builds and signs it and everything
I think the only time I've noticed that was with a PPA that doesn't work any more ;)
In Karmic it'll be really easy to add it -- just tell people to go to system->administration->software sources and type "ppa:emc" and then install the emc package (eg apt://emc)
is there a name for Karmic+1 yet?
I think there may be an even easier way to add ppas too (eg through add/remove or an apt:// link)
usually name comes out after freeze when we start having to say "well this can't go into karmic so we'll postpone it to..."
the trouble is that we also need a realtime kernel, which can be a pain to get right
Yeah I'm not sure of the current status of the realtime kernel
not -rt, RTAI
-rt doesn't work well enough for this
it's getting closer, but it's still a ways off
So you depend on the RTAI package which isn't in Ubuntu?
yeah. there is no package, so we make our own
[12:10:04] <El_Matarife> https://launchpad.net/ubuntu/+source/rtai
yeah, source only, no?
No, that's in the universe package
and is supported so people upgrade it
oh, interesting. I had seen that one before, but I thought it wasn't usable for some reason
(which may no longer be a reason)
of course the page didn't load for me :)
there we go
so in theory, you could make a PPA for this, and have it depend on the RTAI package and apt-get will go out and get it for you
wait, it is a source package
Try apt-get RTAI
I've done dpkg -l "*rtai*"
SWPadnos: you can have ppa depend on other ppa as well
sure, I see that
or just put the needed package in your own ppa
It can't depend on universe packages?
it can too
So PPA for EMC that depends on the RTAI package being installed
Or if the RTAI project has a PPA, you could depend on that
Wonder if those guys have an IRC channel
I still don't see a binary package of RTAI
on Intrepid, using Synaptic and searching for "rtai"
there is rtai-doc, and the RTAI that we package
Are you searching the universe repository?
yes, I have universe enabled
I'm pretty sure that PPA is only for the source
* BigJohnT wonders why the hm2 stepgen vel feedback does not end up as 0 when the axis is not in motion
it should end up at 0, but maybe not for a second or so
oh, from stepgen. hmmm
it looks like some real small number
I wonder if it's dithering between two steps, and therefore outputting a vel which is 1 count per servo period (plus and minus)
I moved the axis back to 0 so it should not be between steps there... I think
yeah. I'm not sure exactly how the stepgen internals work
I think it's similar tot he software stepgen, which keeps track of fractions of a step
it's reporting the velocity at -0.00001220802
what are the stepgen scale and the actual thread period?
scale is 1000
where do I find the actual thread period?
huh. 5TPI direct drive full step?
halcmd show thread
is the stepgen running in V or P mode?
huh. that doesn't look like a step or 1/ a step
is the sign changing or is it steady>
steady after I stop
every time I stop it is a different number
I suppose the driver could use some small "tiny value" and round to 0 if it's that close
ok, that would fit the theory that a step fraction is somehow not being handled correctly
if I go up it is positive if I jog down it is neg
nap time here :)
