Helical Contour Toolpath

[Anonymous]

I try to create a helical toolpath which will plunge 0,3 mm per revolution. However Fusion 360 doesn't create proper helices. It will ramps for a while but then stops ramping and starts to feed flat toolpaths which increases the machining time substantially. I have attached the file. Any help will be appreciated. Thanks in advance.
