Beamo struggling to cut 3mm ply and acrylic

Hi all. I’ve had my beamo for quite a while. Since I’ve owned it, is never done a consistent job cutting things. I’ve tried probably 4 or 5 brand of recommended 3mm ply and almost always have to use 5mm settings and they still don’t airways cut through - maybe half the time. Tonight, I tried 3mm acrylic. Perfectly flat, cast acrylic that consistently measured 2.95mm on my mitutoyo calipers. Agree attempting 4 cuts, it took going to 65+% power and 3mm/s to get a solid cut.

What gives? From day one I’ve assumed I’ve just had bad material, but this should have been way easier on the beamo given everything you see on the internet and the Facebook groups.
