[Bdi4emc-help] quickstep, apt-file

[Jeff Epler]

On the irc channel, a bdi user was talking about what he described as
"ringing":
<approx> it sounds like emc1 pulsing has some kind of ringing when running constant speed
<jepler> what step rates are you trying to attain?
<approx> I have 1333 steps/mm . ringing occurs when running over 10mm/s

I first suggested that he try "quickstep", but then I couldn't figure
out which version(s) of the emc-modules package have quickstep.  My bdi
test machine has "emc-modules-2.6.12.6-magma+bdi.102" and apt-get
doesn't report any newer version is available.  But that package doesn't
have a "quickstep.o".

So my first question is this: Which emc-modules do I have to install to
have quickstep available?

I tried to answer this question for myself by using apt-file, but I got
an error when running "apt-file update":
    --11:28:24--  http://bdi4emc.ourproject.org/debian/dists/sarge/Contents-i386.gz
               => `/var/cache/apt/bdi4emc.ourproject.org_debian_dists_sarge_Contents-i386.gz'

Is this an error on my end, or is the ourproject.org apt repository not set up
to permit use of apt-file?

Thanks -- I'll pass any answers I get along to <approx> on irc.
