So has the engraving capabilities been figured out yet? I am so excited, I have designed about 5 things to be cut already and was hoping for a little clarity, if possible. Will it work like a grayscale topo, assigning deepest burn values to the darkest grays, lightest to lights, etc? Do you know the approximate depth that can be burned from a typical piece of MDF or Birch on one pass? Are we talking 1/16" or 1/100"?
