    A few things I might consider/think to try:

    • How old is the PLA you’re using? Is it possible it’s absorbed too much moisture?
    • Are you printing too fast or possibly under-extruding?
    • Skip the glue. I’ve found it’s just gunk that separates the filament from the print bed, worsening adhesion in my testing. Clean your print bed with rubbing alcohol before hand.
    • How old is your nozzle? If you’ve been printing for a few hundreds of hours, the inner diameter of the nozzle might be worn out.
    • How hot is your print bed? For PLA, I’ll usually keep mine around 60°C.

    I don’t have a Bambu, but these are a few of the things I’ve learned with my Monoprice Maker Select v2 and Ankermake M5.

      99% of printing issues with PLA are solved with a thin film of glue stick.

      IPA does not remove oils, it solubilizes them and then they deposit back down again when it evaporates. Soap and water is better because it removes oils and plasticizers.

        You don’t dump alcohol on the plate and then let it evaporate. You put it on a paper towel or microfiber cloth and rub the plate so the oils are transferred to the paper towel.

        Dish soap can be problematic because many brands include oils to be soft on hands. Palmolive is named because it has Palm oil in it. Dawn has Palm oil too

      (it was solved by washing the plate with soap)

      The PLA is a week old, but it was 10$ no brand PLA which might be an issue.

      there nozzle might be about a year old,

      I’m using 60°, but tried 70°

      thanks for your answer
