If the surface is not ending against a wall, you can extend the surface by 2-3mm

Also in "Gaps" the tangent arcs entry/exit is an option, ( not available if you use "Follow Surface" )

Another is "Direction", this is a added linear lead in/out, do not use with "Zigzag", it is best to set this after getting the surface parameters correct ( check the endpoints of your surface paths carefully if using "Direction"
