Thank you for this information. I am relatively new to 3DP. I did see the repair button but assumed something more fundamental must be wrong.
I was under the (probably false) assumption that if I saved as STEP from Cad, then Studio might convert it into a ‘better’ STL file upon from that vector format, as opposed to saving directly as STL from Cad. But maybe you are saying there is no such advantage? My Cad has default STL settings but I can override them to increase resolution/density. Before I got my A1, I was making files for a friend, providing him increasing levels of resolution without really knowing much of anything. Of course the files got larger but he said there was no discernable benefit. Maybe he had arrived at the limits of his printer or just a function of those parts. ie. if they are mostly flat surfaces, limited benefit.
I am just about to inserted my 0.2 nozzle for the first time tonight for some smaller more detailed cylindrical parts. Would you still advise to save as STL because that is kind of baked in the Bambu A1 workflow, or continue what I’m doing with STEP & just repair if there are issues?
