You can use UGS or bCNC on Mac, both will display the gcode for you but you have to start them outside of sketchup.
SketchUcam can do simple rotary commands. For complex parts Fusion360 will do all you can handle. For controller, LinuxCNC is very good, and...

Ditch that compression bit! Your cut depth is not deep enough to make use of its compression facility so all it is doing is compressing chips...
bCNC is a bit complicated to start with, you will be better off with GRBL-panel.
maybe you can start with these videos? SketchUcam Howto - YouTube
