Hello, You appear to be new to this mailing list and probably new to density functional theory as well. Welcome. The answer to your question is definitely no. The plane-wave cutoff is highly dependent on the nature of the pseudopotential used for each species in your simulation. There may be recommended cut off values for each of the pseudopotentials that you are using and then you should start with the largest of those values. If you are not familiar with these concepts I would recommend the book Electronic Structure: Basic Theory and Practical Methods by Richard Martin or any number of review articles that might be suggested by members of this list. Good luck.
