I think you can uncheck ramping in the operation setup. On my Haas, I would use a smaller end mill, maybe 1/2 or 5/8 inch and do a adaptive clearing pass at full depth, 6000 RPM, 120 IPM, full DOC, about 0.035 step over, aluminum cutting carbide endmill.

Then a final profile clean up of about 0.005. 6000 RPM, 80 IPM, full DOC

To learn Fusion 360, I would recommend https://academy.titansofcnc.com/ a free online course that takes you from 0 to machining parts in a couple of days. Uses Fusion 360 and Haas machines.
