Saw users,

As you are probably aware, the saw has been misbehaving a lot recently.
Its favorite trick is to assume the ccw limit switch has been reached.
With the intermittent nature of the failure, it has been difficult to
fix it.

The good news: the failure is the limit switch not the wiring or logic.
It is now a hard failure.
The bad news: the saw will be down for a few days while an ex-K&S
service tech is brought in to replace all limit switches, do an audit of
the tool condition, and provide some maintenance training for staff.

The timing is to be determined and I'll keep you posted when I know
more.

Dick

	We think we have identified one of the main
causes of the theta drive problem.  At least one part
is bent, and the service tech is trying to locate a
replacement part.  We may have info on availability
of this part by tomorrow.  I'll keep everyone updated
when we find out.	Len

	We just removed the shutdown on the saw.
Some new parts have been installed, so please

(good or bad).		Len
