The position of the symmetry point is contingent on
the kinematics. If you change the kinematics (such as
switching the head), then the position of the symmetry
point changes as well.
Depending on the kinematics, the positive direction
of rotation of SYM may not correspond to the positive
direction of rotation of SEQ. Therefore, ascertain the
position of the symmetry point and the direction of
rotation of SYM on each machine before programming.
