I would say that was a successful cut. All you had at the bottom was a thin skin and tabs. I try to attain that each time. I use my calipers on each piece of wood I place on my machine and adjust on the setup screen. There is no sense in damaging the waste board too much, but it happens.
This is what I did to help prevent static issues on my machine.
