Still haven't found the problem. The consumables looked OK and the air pressure was good. May do some more cutting today to try and figure it out. Thanks for all your ideas.
My air is as dry as it can get in Houston in the summer. No water in the separator on the back of the machine. It goes through a small separator at the compressor and then on to one of these also http://www.nationaltoolwarehouse.com...FU4F7AodKUEApQ.
