I’m using CuraEngine from the command line and would like to slice two models stacked on top of each other (a cylinder on top of a cube). The lower model should be sliced in the standard way, while the upper model should use the "Spiralize Outer Contour" option. However, Cura does not allow this parameter to be set differently for individual objects in the scene. Is there a way to bypass this limitation? I know I can run the slicing process twice and merge the resulting G-codes, but I’d like to avoid that.
