I am starting this topic again to be more descriptive in the problems and provide better photos.
I cannot cut virtually any wood without scorching it to death and even then, not always. Here is an example
The lens is in correctly:
The wood is laying perfectly flat. I have tried a few experiments with focus. This shows a setting of 140/full (used to cut through without a hitch) at focal points of .1, .2., auto, .3 and .4 respectively:
Additionally, here it is from the side, these are simple lines also at .1, .2, auto, .3, .4:
The cutting is very inconsistent. Every once in a while, the first 3 squares cut just fine. But mostly, they don’t even mark the back of the board.
I need desperate help right now. Any suggestions?
And YES YES YES I cleaned all the optics.
Oh here is the back side of some 1/8 baltic birch…
