The effect of lattice rotation, micropillar tilt, and contact misalignment on the compression of anisotropic single crystals is assessed by means of crystal plasticity finite element simulations. The study is focused in single crystals with the NaCl structure, which present a very anisotropic plastic behavior as a result of the large difference in the CRSS between the two possible families of slip systems. The results show that in the case of “hard” directions for which the soft slip systems are not initially active, like the  direction, the loading stiffness and the flow stress can be greatly affected by small misalignments.
