Hello, I am building a simscape model of a 3DOF model, part of which I have pictured below. The mechanism giving me grief is rather simple, it is just a leadscrew mounted to a carriage. The revolute joint, "Revolute4" is giving me a lot of trouble and I believe it might (?) have something to do with my lead screw block, since this block in particular proved difficult to work with..
Essentially, when I move the carriage, via a prismatic articulation signal, the revolute4 joint will output a motion and position signal. However, when I try to drive this with torque input directly to the Revolute4 (and not the prismatic), there is no revolution of the joint. How do I resolve this? Simscape throws no errors and therefore I am more or less at a complete loss on how to troubleshoot this issue. I have attached the image of part of my project, unfortunately I will not be able to include the entire project but I believe this information is enough to begin with.
