Platform simulation doesn't work

Hello everyone,

I'm student of Mechatronics and I realizes the platform project. Its task is to control the ball on its surface.

I created platform model in matlab simulink. I have a problem because it doesn't work correctly. When I connect all of elements together platform stops wroking. When I disconnect one node platform reacts correctly to the force of gravity. I don't know where I'm making a mistake. I am sending the model in the attachment.

Are there other settings for parallel robots? Where can I find a solution to the problem?

Thank you in advance.

I believe an example of the system you are modeling is available here:

See the animation below. This will help you fix your model.
