Before you start adding layers to your puppets, you should enable the Default Separate Positions
With the Default Separate Positions
By default, this preference is enabled. For cut-out animation, you want to have three independent axes so you can control them individually. When you lock the three positions together, each time you add a keyframe, it is added on all three positions at the same time.
When you separate the three positions and add a keyframe on one axis, it is not added on the other two. This gives you more freedom when animating with motion keyframes and nudging parts forward and backward over time.
