Thanks Neal and everyone else for their help, I have given up now, I can cut 8mm MDF like a "knife through butter", but not this particular plywood, I have tried multiple passes and many settings but the edge is still charcoal.
Most likely it is exterior glue being used or it could be a Chinese version that uses Poplar for the core. True Baltic Birch will cut clean and have brownish edges. Once in a while you will get a black poof of smoke and it won't cut all the way through... It seems, in my opinion, that they (the russians) are stacking the center core with less than BB grade and they are a little more prevalent in knots than normal. OK for CNC and mechanical cutting but not as nice for laser when cutting lots of small items.
Have a Blessed day,

I always heard running at 100% power is bad for the laser and eats up the tube very quickly. Any truth to that?

Trotec recommends 80w for 1/2, other posters are correct that's too thick for the wattage.
