I would like to reproduce the movement of the front part of a hydraulic excavator in Simscape Multibody.

I would like to fix the distance between the pins (cylinder length) in order to create the maximum reach posture of the front part, but I do not know how to do this.

Currently, we are trying to adjust the limits of the Cylindrical Joint and the Revolute Joint to get the behavior closer to that of a real excavator, but we are not fully aware of the effect of the limits.

How can we fix the distance between the pins and create the maximum reach posture?

I would appreciate it if you could help me.

Thank you in advance.
