On the other hand the rotation around the X axis (red) is already prevented by the Base-to-Crank joint; and so the corresponding degree of freedom (dof) is constrained twice (= redundant) and causes the warning.
 * To avoid this redundancy an auxilliary object and corresponding constraints could be inserted, but that is for some other tutorial.
 * To avoid double constraining the offset between base and Rod, different constraints were used, with only one of them fixing the motion along the Z axis.
