    2) What you see is probably the out of wing panel movement to keep the cutting synchronized. Understanding it and why it happens need some knowledge about foam curring cnc strategy

    Still struggeling with profilipro cnc strategy. This is what I meant, shown by a simple cnc cutting path simulation (for explanation only). I progammed a rectangular foam panel, constant profile, simple spar cutout and simple lightening hole to show what I mean.

    ProfiliPro prescribes to first cut the spar and lightening cutouts. According to the simulation, the hot wire will be immersed into the foam block from the top along a vertical path:

    Then, as a second step, the profiled wing panel is cut:

    For me it looks, as if there will be no usable top foam negative mold remaining. The top foam negative mold will be cut into three pieces. Is this intended? How is the procedure, in case I want and need such remaining one piece negative foam mold? Any workaround?
