sounds like you might have told the machine to stay under the rollers.
and with your piece being only 6" long . What happens is when you tell it to stay under rollers it starts carving 3 1/2" from the end of the board. the machine usually asks to if you want to size the project to fit board.
The minimum length is supposed to be 7". and you 'll have to tell it not to stay under rollers.
also to get a raised pattern you will have to carve away everything around the pattern .
