This is pretty cool. Can we supply our own shapes? Can it rotate them? Can we specify edges that we prefer stay vertical or horizontal? I often need to CNC things out of plywood and it takes a surprising amount of time to lay out while making sure that the bit won't cross through an adjacent piece, but at the same time you may need to pack them into a small area to not waste wood. Good packing can make the difference between needing an additional $150 sheet of wood or not.
