Depth of cut Beambox Pro


I’m not even sure if this is the right place to ask this question… I’ve just ordered a Beambox Pro while waiting for delivery I thought I’d do some extra research on the machine. It states 8mm cut on wood (probably balsa wood) does anyone know what depth I might be able to cut on oak?


Ive been able to make a 6mm cut, but it was not clean and left a lot of char. Even a 5mm piece presents challenges if its too far from the origin point. Im sure someone with more experience or know how would be able to help more, but Id be surprised to see it cut more than 6mm.
