Automatic Sliding Tool Rack For my Q408

Hello everybody,

I would like to add an automatic sliding table to my brand-new Q408, similar to this system:

Unfortunately, this system is no longer available, but I can build one myself.

My question is: does anyone have this system? If so, could you tell me what G-code activates the sliding piston and which output it uses? My ATC works fine, but I need to control the sliding rack with some G-code.

Thank you !
