No other configurations for SCARA mechanism

#1
Hello,

I made a simple 4 axes SCARA robot with the mechanisms builder. Everything works fine expect that I cannot select alternative axis configurations for any targets.

Where I expect it for example to have both joints solutions (θ1,θ2,d3,θ4) [45.00°,  90.00°, 0.00°, 0.00°] and [-45.00°,  -90.00°, 0.00°, 90.00°] as possible configurations for a target. Yet it only gives the current solution and no alternatives. While an alternative config is possible as I can axis jog into it and even force it by programming a joint target close to the desired config before moving to the target.

Iterative inverse kinematics is on.

You may need to increase your robot joint limits to see all possible solutions.

Can you provide us with your RoboDK project file? (RDK file)
