For all Onefinitys without a tool setter, you must separate each tool into it’s own file.
The BB controller is limited and unable to jog/move during a tool change, so it cannot do tool changes.
The Masso controller only does tool changes with a tool setter.
Whatever you are watching or people you are talking to are not using Onefinity machines.
The final answer is any Onefinity machine that does not have a tool setter must separate each tool into it’s own file.
