I can see why you don't want to take the Roland to shows... But why can't you cut smaller scraps? Your Roland specs go down to 2" wide material can be cut. Your pinch rollers move,, so you can cut smaller scraps. And anything smaller can go on a carrier sheet.
A few years back I had to teach a Roland owner (of 7 years), how to run his machine, because he didn't want to read his user manual. I don't own a Roland, I just read the user manual. I asked him the same question, why can't you cut smaller scraps? He bought another machine also, just to cut scraps. Oh, He didn't know the pinch rollers moved.. There may be a set screw to loosen, but they do move.
