Testing acrylic today on my new 55 watt Xtool P2 Co2 laser. I started by testing the unmasked acrylic scrap by placing it directly on the honeycomb (oops, I forgot to lift the acrylic), and as expected, I got flashback, (lovingly known as tick marks). I then raised the acrylic off the honeycomb with some scraps, which eliminated the flashback (as expected). The cut was smooth and very clear.
Raising your acrylic off the honeycomb to prevent flashback applies to most CO2 lasers. Thus far, I'm loving this Xtool P2 laser; it complements my Aeon Mira 9 and fiber lasers perfectly!
