voxel rotation animations are broken, and are offset from center along the x axis this calibration tool goes from 0-31 starting on green for 0 point on each axis with the black dot in the perfect center. Yellow represents the Y axis, Blue is X axis. For this 31x31 the rotational center is exactly 3 voxels from the center, at X:19 Y:15. The true native center is X:15 Y:15 and thus should rotate there.
