I have the same problem, Dennis, with my bigger, fancier, more expensive 650 (I think that's the model number). It has production stops, which are nice, especially when you're cutting multiple windows, and it will handle boards up to 40" wide. It in theory can cut 8 ply mats as well, but it always curves the cuts on the 8-ply. I wish it was more reliable in that regard so I could cut my own 8-ply mats which just look SOOOO nice when done right.
