When I get to it, I worked with my scanner and legal stuff that had to be emailed a good bit of the day. And I'm about spent. Some small adjustments made and another 5x5 is in progress now. And I can see that I can lower the temps a few degrees and still get adequate adhesion to the glass. Still fine tuning IOW.
