Artisan and Lightburn/Fusion 360

Is anyone having full success using Fusion 360 or Lightburn to generate your G code for the laser then importing it through Luban? I am running into issues with Lightburn. The laser is not getting up to speed. I do not believe it is getting over 2500-3000 mm/min. Also, I do not think the Overscanning is working correctly. I have not fired up Fusion yet though.
