Hi All,

I tried sending to SVGCOAT2-pcs (through coral), but it bounced (see

I think SVGCOAT and SVGCOAT2 are now both working, at least to a
yellow state.  SVGCOAT2 is in shutdown, but I feel is definately
up to yellow, at least, for further testing.

I can't change the status in coral.  If you get this, and you can
change SVGCOAT2 from RED to YELLOW, it would be appreciated.
Both machines are written up in a comment on coral for the current
status.  I'll try to do further testing on SVGCOAT2 if it's made
yellow.  Since the steppers are coming back to life, it would be
good to have both tracks back online for the weekend!

I found several problems:
One of the roller bearings on the main track was
out of alignment.  This means that the spindle cannot
reach (and seal vacuum with) the wafer when it comes up
to meet.  I put the bearing back on track.
Also, the vacuum sensor is really in bad shape.  It looks
like it has been sprayed too much with solvent, and
the buttons are therefore "welded" in place, and the display
is crazed so it's difficult to read.  It's working ok at this
moment, but we should probably have a new one
(or five) on order.
Also, I think the chuck may have been loose on the
spindle, but I don't know for sure.  In any case,
I re-seated it.
It's still shutdown, so I can't fully test it, but in manual
mode, at least it can grab a wafer, pull vacuum,
spin it, dispense, and release it.  I think it can safely go to
yellow for further testing.
