Constraints problem with barrel cam and roller

I'm struggling to get a cylindrical cam to play with a roller, in my screencast I have both rollers in place but I have been trying to get it to work with one. Beginning to think it (the software) doesn't like my swept surface, I have been trying to use a transitional constraint as suggested in youtube clips but also a lot with a tangent constraint.

The idea is that the shaft will be the input and the yoke that holds the rollers will have a reciprocating linear motion. I'm aware that there is a feature to design cylindrical cams in Inventor but I wanted to roll my own (yes, pun intended). I'm using Inventor 2015.

 

Any ideas or help very appreciated.

 

BR,

Mattias

I found the problem, the shaft was slightly misaligned.
