D' you do have to adjust when using wood and I don't care what machine you are using. And if you get it perfect it won't be once the weather, material or shape changes. It is the wood moving my friend. The male more than the female, but both do.

As I think you may know I make inlays for a living, so again it is not your machine, all mine do this for inlays. If I make a .5in plug my males are .5125 for a perfect fit on one machine, slightly different on another.

Anyone can say I am wrong, but with so many machines and near 600 floor inlays under my belt I am saying it doesn't matter. If CNC is the hobby then strive for perfection, if the end game are the woodworking results then just know you need test every project and that male has to be adjusted to fit the female, end of. Once I was resigned to that I never looked back.
