3ds Max animation robotic arm - problem

awsedr9

Mechanical arm is interconnected and all joints function and hold together..
When the animation starts the end point makes arc trajectory. How can I make it to do a linear trajectory? THNX

run a HI-Solver from the rotator on top of the base to the nozzle pivot. there should be 1 pivot between start and end. then animate the IK target from A to B.

Thanks, but i tried.
this is OK, but it is only inverse kinematic : 0° - 180°.  
I need movie arms like this gif

you got any context to that gif? looks like some kind of custom tool from Duber. probably not something that can be replicated easily. you might try 2 IK chains and swtich the arm in between them.
