If I may make a suggestion, you need to increase your feed rate or decrease your spindle speed. I see some burning in the corners meaning your going to slow and the chipload is to low to remove the excess heat. I would also recommend using some type of processed material as stock; wood has a grain and in a unclean piece with a knot the varying hardness can make you miss steps (assuming your cnc is stepper based).
