@Maratk1n, are you saying that the Get_Weight() function is very slow and is blocking other actions?
If so, maybe there is a solution, but I can't see how we could have inferred that that is the problem from your Original Post.
I think you need a different function to read the HX711 - one that starts a reading but does not wait for the answer and periodically checks to see if the answer is ready.
Maybe the library already has functions that facilitate that?
