Dissapear weight shipping over a total cost

I want to ask you how can I dissapear totaly the weight based shipping over for example 50 euro total cost of order ... Now I can see and enabled the free shipping correctly but as an option I also have the cost of weight based shipping enabled and appeared on the checkout cart that is not correct. Is there any way to dissapear this option if free shipping enabled?
Thank you

If you need to disable other methods when Free Shipping is available, you can use my tutorial here:

If you want more flexibility in how you set up your rates, using weight + total criteria, you could use Formula-Based Shipping.

Thanks for your answer ...the biggest problem solved ...the only problem that I have now is that I have on a specific place receive from the shop and is activated and dissapear the free shipping method when someone cannot come to the shop and wants to send them free (free shipping) by the courier.
