Hi,

You could try Mechanism Wizard to solve follower joint on this kind of closed loop system. Add-on can be found here:

Mechanism Wizard

Hi, Mechanism Wizard add-on helps you solve follower joints in systems that form a closed loop. Like the SasaHelper add-on (SasaHelper for modeling follower joints) Mechanism Wizard solves follower joint expressions with sasa-functions. The difference is that SasaHelper only measures the system but Mechanism Wizard tries to solve the follower expressions completely and write them into follower links. Mechanism Wizard doesn’t solve every type of system but usually you can model the system in a w…

I tested it on your model and it works if you first make rotational joints parallel. Mech wizard is little picky about that. Here’s a video on how I aligned joints and then used MW to solve followers:
