Just running a few tests to home in some settings for the weekend,
12mm poplar plywood 3mm/s 90%
3mm MDF 25mm/s 90%
6mm Acylic 3mm/s 90%
Those are very nice speeds! So looking forward to assembling my own and burning holes in all kinds of stuff! 
@CescoAiel The speed surprised me too
We cant wait to get our lasers out in the world 
But sadly we have to wait a just a little longer
