I have written a tutorial on how to simulate a slide crank as done in the sky engineering tutorial below.

I hope it helps. The tutorial is in the WB's repository wiki; linked below.

There is a bug it the axial rotation joint and the revolut hinge joint. the simulation still works it just not quit the way it is supposed to, The bug fix will not change the tutorial.
The first picture shows the initial position of the mechanism. you can see how the parts side by side(not overlapping). The next picture shows the final position of the mechanism. you can see the part overlap. That is not what should happen.
I know how to fix this case, but my misunderstanding of how the MBDyn works makes me less confident this will fix it in gerneral.
