Gcode Creation for CNC Router

I need an STL file converted into a Gcode file for Candle, compatible with a Genmitsu 440PRO CNC machine. The project involves routing a basic design onto hardwood for a folding knife. I have only a few different bits but after looking at the file U didn't mind recommendations on what to use...
