SolidWorks for makers, post processor for LinuxCNC?

I am trying to use nc shop floor, the cam software that comes with SolidWorks for makers. But what postprocessor should I use?
The shop floor program is difficult enough, it's totally illogical, and now I am not sure what output to use.
Can anybody help?

one of my mates has a license to Fusion 360 for the cam part.

I use the excelent Path workbench in FreeCAD now to make stuff. I design in SolidWorks and export a step file. The step file I use in FC to make code for LinuxCNC.

@ikkuh, I'm new to CNC, in the process of setting up my first mill. I also draw parts in SolidWorks (3DEXPERIENCE for Makers). I'm trying to figure out the cleanest low $$ path to get from the part drawing to GCODE to run the mill.

I have used FreeCAD in the past. I have zero experience with LinuxCNC. So you import an STL into FreeCAD and use Path Workbench. What do you output from Path Workbench? I have my mill, but have not selected controller, SW, or steppers/servos yet. I'm trying to understand the flow better before I spend $$.

Thanks for any insights.
