Okay, that particular file has a couple of issues…the main one is overlapping vectors, and unnecessary paths at the outsides of the bed. (Lose the outside rectangle.)
I was able to turn all of the colored filled shapes into a compound path that will engrave fine…what you want to do is just use a Fill color without a stroke color for the engrave areas. For this design, it’s necessary to turn all the shapes on top of the back shape into a compound path, and then subtract them from the back shape to wind up with the final compound path for engraving. It loads without issue, and looks pretty sharp.
