It looks like you need to increase the acceleration of your motors. The machine is trying to blend into the next cut. You can increase your motor's acceleration and see if that helps, or you can turn CV off and turn Exact Stop on, that should take care of the issue whether the accel on the motors is slow or not. G64 turns on CV G61 turns on Exact Stop.
I would turn on Exact Stop (G61) only when doing finishing contours; Keep G64 on when roughing.
