In printing Compact poop bucket L (A1, A1 mini) - Free 3D Print Model - MakerWorld I see banding that is at the same layers as the holes in the side. I am guessing that this is related to those layers taking much longer to print that the ones without holes. Past that, I could use some suggestions as to what to adjust to try to eliminate this kind of defect in the future.
It was printed using the 0.20 mm Standard @BBL A1 with Bambu PETG HF selected as the filament. 2 Wall loops (default) and I don’t see indications of any overrides.
[Edit: I had reopened a copy of the project that was not loaded into Bambu Studio. I have edited the below to reflect what I believe to the be the profile overrides and details in use]
Other layers speed shows:
Outer wall: 50 mm/s
Inner wall: 50 mm/s
Small perimeters: 50% (default)
Sparse infill: 90mm/s
Internal solid infill: 90 mm/s
Top surface: 90 mm/s
Gap infill: 90 mm/s
Slow down for overhangs
Slow down for curled perimeters
Seam: Back
Smart scarf seam application (default)
Scarf joint for inner walls (default)
I just went through this issue on an H2D! For me it was the pre start fan time in the fillament settings. It is set to 2 seconds, I switched it to 0 seconds and the prints turned out much better. Original user who helped me was @hotellonely, just figured I would give credit where due if it helps you.
Changing the pre start fan time to zero cleaned up the banding and didn’t seem to have significant impact on the overhang/bridge appearance on the holes. I do see some defects in the raised logo, but figuring out how to locally modify the parameters will be a learning experience for another day.
