RobotStudio event

Creation of an controller

Options
Hello.

I created some mechanisms as a positioner ( blue part) (external axes) for my station because in RobotStudio's bookstore there was not what I was looking for.
I did all the graphic layout but when adding the mechanisms in the virtual controller from Layout I can't add what I did, I can only add the robots. I have also added the external axis wizards add-ins.

Can someone help me?
Thank you
