I have a curious issue where I've designed a set of 5 valleys 1/2" deep and 10" long. (see attached)
The roughing pass went as expected but the finishing pass only cut on the left side of the valley and the very bottom of the trough. The right side of the valley didn't get touched.
Top 1/2 of attached shows both sides.
Bottom 1/2 shows the details of each side of the trough. Left is smooth; right is still rough
