I know there is a thread on this subject but cant locate it. So it finally happened to me ,Carving about done and power goes out. So to save the carve you need to put a carve region over the previous carved area and finish the carve, Ok when I do this it gives me a carve region but it still has depth, some of the carve showing thru carve region, Even though it has zero depth I can see that it still is not flat with board surface??? what am I missing here Thanks Mike
