Hi Frank, this is a nice and laser-technically interesting picture. It will be exciting to see the finished result. But the road to it is long and you have to test yourself with all the many setting options. Make a small representative clip and test, test and test.
You must also pay attention to the wood surface itself and the fiber structure, here I always try to orient the natural wood lines with, for example, the horizon or “at an angle” to something that does not irritate one’s eyes. Some pre-treat the wood with a baking soda solution.
Good luck and remember to show the result
