Suggested Solution: This should be avoided by slicing a better path (detect floating wall and print last on applicable layers?), and/or the user should be warned about the problem.
I spent a long time adjusting settings to try and fix the problem because I did not expect the slicer to do something like this. Now that I noticed the issue, it’s printing quite well with “print infill first” turned on.
Thanks, that makes sense. I tried to find topics covering this, but I wasn’t searching for the right thing.
It would be really great if Bambu Studio detected this problem, warned the user, and at least linked to some documentation to describe potential solutions like the one you provided.
It should be fairly simple to detect, since it’s trying to print a wall in thin air with a significant gap from the last layer?
Hopefully this would save other newbies from wasting as much time as I did on this.
Not sure if “convert holes to polyholes” setting in orca slicer has any bearing on this, but I only just today became aware of that setting’s existence, so I’m just mentioning it in case it’s relevant. Probably offpoint, but I won’t remember to mention it here later.
After several years and several software updates - this rather serious problem still persists. I have seen other slicers print successfully 90 deg over hangs for several inches with perfection, why this has not be resolved years ago is beyond me. come on Bambu, you can do better, it can’t be that difficult. The is a tapered overhang, like 22 degrees angle, and it starts by printing the first layer 1/8" away from any wall or surface - out in mid air. I suppose this is a great way to sell extra filament.
