It’s kind of a balance with speed and power and number of passes because the char buildup can lead to non-desirable results. I think I do 700 speed and 60% power and three passes. Cherry, maple and walnut all behave slightly different so you need to test them. The best thing is to get a small test square and use that to see how it works. Start with two passes and see how that works.
I use this as a test file.
