What are you using the opticut 150 for? I imagine these machines are used for cutting large volumes of softwood for sheds, cabins etc. I can remember using one in a pine furniture company, it was used to cut unsorted redwood to length before being planed on a Weinig 9 head machine and assembled into panels. They are clever machines with optical readers that can cut around defects and optimise cutting for mininum waste. Then one I worked on got through 40 cubic metres a day.
