This was kiln dried cedar. It wasn't warped and if you look at the pics, it looks to me like it is a toolpath error. You see how it dug down in one pass to create the groove then moved back to it's normal height. The material was held flat and after carving did not bow or warp so it is not a materials issue.
I have seen others post similar pictures but i don't recall what, if any, their solutions was? Or if this is just one of those things where "gremlins got into the computer and maybe with another shallow pass i can get rid of it.
