From point A to point B in JUMP mode:

If point A and point B are only different in Z-axis, but the arm orientations of them are the same, Dobot M1 will not work.

If point A and point B are the same, only different in arm orientations, for example, the arm orientation of point A is left, and that of point B is right, point A moves to point B as the right hand posture, while the terminal coordinate relative to the origin stays constant.
