I tried 3d print glue stick. washing with alcohol. wash the nozzle, cold pull, higher bed temperature… nothing,
the i has 3 successful prints with the same file, and now for the life of me I can’t get it to work
- I had similar issues not too long ago and washing the plate with soap and warm water did the trick. .Made sure it dried for a day too just in case. - THIS!!! THIS IS WHAT WORKED - ANYONE IN THE FUTURE WITH THE SAME PROBLEM CHECK THAT - Heyoooo, glad I could help! 
 
 
- 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. - (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 
- 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. - 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.
