Without further information, this looks like a plate that requires a simple clean.
Use a warm water and standard dish soap mix to clean off any residue and oils from fingers that build up over time.
This is a normal consequence of 3D printing.
Once thoroughly cleaned and dried, try again.
I would recommend printing a single layer test before to verify it’s completely clean. If you don’t have a file to use, you can easily make one as follows.
- In Bambu Studio create a new project
- Right-click the plate and add a part
- Change the dimensions to fill your plate and 0.2mm height
Print that, if it is flat and without any imperfections, you’re good to go.
