Thanks. I tried that myself. Here is the full slit version. It gave me kind of ambiguous answer: Both ‘OK’ and the same ‘floating cantilever’ message. You are saying its a warning but not a critical error? I also should have shown the whole part because I assumed it was related to the slit feature but maybe by re-orientating a new issue arose? As mentioned if I suppress the slit no warning at all. It could print on the main face.
