    you could always use 3 axis wire frame
    albeit more time consuming,you would have to draw your tool path and draw leads and compensate for tool size

    this is contour ramping in 2 axis
    just enter the same feed rate for x y and z
    set feed plane just above the part something like .010-.020-.030 default is .100
    do not use a leadin
    use depth per pass and set it shallow to start (not knowing what cutter or material) cutter is critical musst plunge well
    finish pass would always be a sraight line cut
    if you want to use ramping for finish pass, just use side allowance for rgh and "0" for finish pass

    this is very useful toolpath
