I do not know how to put my xbox one in main because when I want to put my xbox one in the main there is a message that says that I reached the limit.

How to share Digital Games and XboxOne?
To play your games on another console you have to use the settings of my Xbox Main.
Here I tell you how to do «My main Xbox»
The first time you log in to an Xbox One and save the password, that console becomes your primary Xbox. Your main Xbox allows:

Share games and downloadable content purchased in the digital store with anyone who logs into their console. You can even share downloaded games as part of a subscription.
Share your Xbox Gold subscription with anyone else who signs in to your console.
If you have more than one Xbox One console or if you log in to multiple consoles, I recommend that you assign Xbox One as the console you use most frequently.

Designate an Xbox One console as your main Xbox.
Note You can only designate only one console as your main Xbox.

Scroll left from Home to open the guide.
Select Settings
Select All settings.
Select Personalization
Select My main Xbox
Review the information, and then do one of the following actions:
Select Make this my main Xbox to designate the console as your main Xbox.
Select This is not my main Xbox to remove the designation.

say you changed your Home on the 2nd Feb 2016, 5th March 2016 and 9th Sept 2016, you only have to wait till the 2nd Feb 2017.

Its 1 year from the third previous change on the HOME.

Hope that helps

If you want that counter reset then you will have to contact support directly as they are the only ones that can do it. Keep in mind since there is a 3 change per year limit they are not obligated to do it but definitely worth a try.
