I don't know about other folks with 500's, but the smart sweep on both
of my machines has never worked properly since the installation in
August. I ended up reinstalling the Buildstation software and disabling
the SmartSweep option just to gain reliability. Phantom sweep stalls
were the most common failure mode, but it also intermittent
functionality was a problem (ala your described problem).

There have been field fixes using command line codes (deadbaud=1200) and
new cables with EMI suppression magnets to no avail. I'm still waiting
for 3D to fix it -- they've got my money, but I have no (quality)
product. It looks to me that they are ignoring the problem which tells
me that there is no fix. So the moral is......caveat emptor.
