I have never cut on this material. However, you have a great piece of “waste” material from the interior, use it to make a test cut/engrave.
Actually, for this specific example, it lookes like only the small cuts for the holes didn’t take. make sure they are Cut not Engrave or Score. Leave the plastic on this one until you manually drill out the holes, then remove the mask.
On subsequent ones, set the holes (if they are separate from the rest of the design) to cut twice or 3 times. Use a piece of duct tape to lift the holes first on the next one(s), so if the holes aren’t complete, you can just run that part again w/out losing registration.
Way cool design!
edit: the Focus (out of focus) I would use to smooth and enhance the engraving, but cutting should focus all your energy where you want the separation. [Unless you need a wide kerf, then cut multiple passes.]
Hey you experts out there, chip in if I’m wrong.
