Help on Basic Motion in Solidworks

I have a model of a tipper and I want to use basic motion to demonstrate how it moves. Currently, I have a actuator pushing my tipper along a path mate which works fine in the animation section. However, I would like to use the basic motion as I would like to include it tipping an object off the surface into a container. When I am using the basic motion, it will not slide along the rails up to the end and then tip over. Instead it tends to jump around and fail.
