I have the 80w Trotec, awesome machine. I suggest 1.5”, 2” and 4” lens. Those are the 3 main things that make your CO2 so versatile, and I would get them before any of the accessory beds. You can cut and engrave Anything on the basic cutting table that comes with the machine and a few scrap pieces of acrylic for spacers. I do not cut much wood so no comment there, however the 80w is awesome for engraving wood, laminates, marking aluminum, and acrylic. The 80w will cut through 15mm acrylic in one pass with no trouble approx 10” per minute. I haven’t tried thicker but I would guess 20mm would be about the max thickness in 1 slowwww pass.

As for other items that I sure use a lot would be a digital caliper, and blue masking tape.
