Thanks Guys for the reply.
I'm interested in the method of capturing the tool holder in the carousel. Instead of the traditional fork capture (more common design - used by the system upnorth is speaking of (I think)). the tool holder is inserted in the capturing device in the carousel and a solenoid energizes and captures/releases the tool holder. There must be a return spring on the solenoid but I just can't get my head wrapped around the design. I may be over thinking it but a peek at the real thing would be helpful. Again, nothing commercial in my efforts, just want to try a new design. The Torus Pro is not the easiest design for a tool changer.
