Yes, different types of wood can require different settings on the miter box in order to get accurate results because different types of wood may be thicker or thinner than others and require a specific angle when cutting. You should also adjust the saw blades so that they are perpendicular for straight cuts, or at an angle if you plan on making angled ones. Next, firmly clamp your piece of wood into place so that it won’t move while you cut it. Lastly, make some test cuts with scrap pieces of wood until you get a feel for how to make proper cuts in the box without damaging them before working on your project.
