I tried to duplicate Motion Analysis phenomenon manually. When Driver Shaft manually rotates Driver legs must travel along the designated Driver Shaft path. But sometimes Driver stop rotates when mated leg comes at the middle of the Driver Shaft. How to fix this?

Only one leg has tangent relation with Driver Shaft path. If more than one leg has Driver Shaft will not rotate.
