Hey guys,
I am using Bambu lab sunflower yellow. I have dried it, and washed my plate. With this particular filament the first layer looks like shit, but the rest of the print turns out fine. Other filaments have proper thick lines of equal height and so on.
I only have a problem with this particular color sinw opening the filament. Is it just the filament being shit or you can think of anything else I could check?


Any chance the filament is unevenly extruded from the manufacturer? Try measure the spool in few places with some calipers to verify that the filament thickness is exactly 1.75mm, and that it doesn’t vary.
Also, might be worth it to check your flow rate/extrusion multiplier setting to ensure that the amount of plastic extruded matches what it is trying to do.
I have read that the Bambu filaments do not guarantee with same thickness very well compared to other manufacturers (0.03mm instead of 0.02mm tolerance) and this could play a factor with small nozzles. I had in mind to try other manufacturers, but they are not so easily available for similar price in my area, so I have postponed it until I finish my current project, but I am keeping it in mind.
I should probably buy some calipers and actually measure it.
