Unexpected Joint Posture When Moving from Home Position in RoboDK

#1
I’m creating a motion path using points, but when I command the robot to move from the home position to a point in joint mode,
the second axis of the arm moves downward (see image1).
What I was expecting, however, was the arm posture shown in image2, and I don’t really understand why it turned out this way.
I think I could resolve this by adding some intermediate posture between the home position and that point,
but could someone explain why the arm ended up in this posture?
Also, in what situations would the configuration shown in the third attached image be used?
I’ve tried reading the RoboDK documentation, but there are still parts I find difficult to understand,
so I would appreciate it if someone could explain.

A joint movement to a joint target should show the behavior you are describing.

Can you send us your project with the 2 targets you are referring to? We can better take a look.
