Fusion isn't designed to output raster toolpaths needed for area engraving. there is an autocad dxf post output that you could use to get a dxf and then try some 3rd party software. 

 

If you want to keep it all in fusion i put together a hacked version of the grbl post that should work.

 

Not sure how you are controlling your laser but I have assumed that M3 will turn the laser on and M5 will turn it off.

 

The attached post is a modified version of the GRBL post that should work with any of the 2D Toolpaths (may work with 3D but didn't test). It turns the laser on (M3) when the cutting process starts (ignoring any lead-in parameters) and turns the laser off when the cutting process finishes. You should be able to engrave areas using a 2Dpocket or 2Dadaptive command and a small tool diameter. (Fusion might choke if you set the diameter to small).

 

To give you an example in the tool path shown below the laser should be on only for the parts of the path shown in blue and will turn off when the path is not blue (e.g. lead-in, lead-out, rapid, helical, etc.)image.png

 

 

Note: This is not a particularly pretty solution the code will have extra M5 commands etc but it should get the job done.
