3/4" red oak, 100(4ipm)/full(100%)
57 second cut, focus at the surface.
Seems power dwindled towards the end (cut left to right) Counter intuitive because according to the grain, the left where the grain is tighter should be where it is harder…?
Anyway, no problem cutting a solid 1/2" of hardwood.
Interesting to see where the laser ‘dips’ into the softer grain. 
Edit; This is a prerelease unit, and for all I know it might be equipped with a hot (pro) tube.
