Roughing and Finishing 2.5 STL file

I want to be able to rough a STL file and then finish. I have a 3018 and it just cannot take 1/4 of material all at once. I have tried different processes and changed settings everything and then when I animate it does everything at once. I am sure there is a way but just cannot figure out. I love the software program BTW and did my first trace feature yesterday.

You want to run roughing and finishing as separate files? Then for export, choose the .zip file option which separates ops into files.
