I am experimenting with ninjaflex and having a Ormerod (Bowden extruder) I cannot use retraction, thus it is very important to be able to never cross perimeters, so every oozing remains inside the print.
So I used the "do not cross perimeter function", but to my big surprise Slic3r 1.1.9 fails at doing so while 0.9.9 totally wins!
