Not sure I'm fully understanding... but if you want to cut first, then use the laser to engrave, you could make a template. Use some stock (birch, MDF, acrylic) and use the laser to cut out a shape that's the same as the one you are wanting to engrave. Then you take out that cut piece, and insert the thing you want engraved into the hole. Poof, you just made a template and you know right where the borders are for your laser, and everything is aligned. Just save the file that your laser used, and mark the template so you always know which is the upper left and top, and you can use it with pretty good repeatability.
