Subject: Wafersaw operational ... but please be careful.

K&S Wafer Saw Users ...

After a lengthy down time, I believe that the K&S 775 Wafer Saw is
operational.  We believe that the occasional "dropping of the head/blade
assembly" was due to an intermittent fault in the 5V power supply which has
been repaired.  We have also replaced the spindle drive and have repaired the
theta stage.  Finally, there had been a problem with the cut depth adjustment
that we believe has also been repaired.

So, the shutdown has been removed and the saw is once again operational. 
However, because it is increasingly difficult to get spare parts and support
for this machine, please treat it with extra care.  In particular, if you
don't know how to do something .... please ask rather than making an error. 
Also, if you see some strange machine behavior, please report it so that we
can try to look at and solve problems before they become troublesome.

Finally, do some test cuts on a sample wafer before putting your real wafer at
risk ... 

Good luck,

John
