The answer is yes. Probably every user on this forum has engraved or cut very similar wood. The "real" settings are 100% dependent upon your fixture, expectations, individual panel properties, wood gain, and which direction you are burning in, and phase of the moon. I would plan on having a test panel and spending time with Ralphs's test patterns and procedures. Then etch a small image and post the results.

I use a lot of the 3mm birch plywood (from eBay). I was never pleased with grayscale on this material, even sanded smooth with 320grit. I guess I never liked the "brown" look or the steaking at light shades. I fall back to using dither at 254ppi (.1mm). I use the bitmap dithering in Photoshop. It still takes many trial burns to even get that looking good. Sorry I don't have any secret formula for you. Just keep experimenting.
