Engraving star for an American flag

I am having a heck of a time getting the starts for an American flag engraved the way I want. Using an engrave toolpath with a 60 degree (30 degree on one edge) v bit and a depth of 5mm, I get this. What I want is to eliminate the center "mountain" so all 5 rays of the star meet at a point. Changing bit size and depth only changes the size of the center mountain. Any ideas on how I can get rid of that?

 

My model is attached. Please ignore the size of the body. I had other sketches I was testing out and removed them to de-clutter.

Please attach your model.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I attached the model to my original post. Thanks for having a look.

You have the depth set to -5mm, try -10mm:

p.s. If you change to a 90 degree or 120 degree bit, you won't have to go so deep.

I don't use the engrave toolpath much,  but I'm pretty sure will need to do some sort of clearing tool path, like adaptive clearing or pocket, in order to get rid of the mountain.
