First layer adhesion issues could be related to incorrectly selecting the plate type in Bambu Studio.
For example, if you slice a model for the Cool Plate and print it on the Textured PEI Plate, there is a high chance the model will not adhere to the plate as expected.
This is caused by the different plate proprieties and requirements. The Cool Plate requires around 35C for PLA while the Textured PEI Plate requires around 55 - 65C for PLA.
The Textured PEI Plate also has a different Z offset which impacts how close the nozzle is to the print surface for the first layer to be printed.
Selecting the correct plate type according to the filament used, while also ensuring the plate is clean before starting a print will give you the best chances of success when printing.
We strongly recommend to wash the plates with hot water and detergent before printing to remove any debris or contaminants, and avoid touching the surface.
This solution solves most issues related to adhesion, as long as the right settings are used for the materials you are trying to print, and the correct plate type has been selected in the slicer.
In some rare cases, the bed leveling from previous calibrations might be inaccurate leading to inconsistent adhesion to the plate.
If you encounter issues with the quality of the first layer, we recommend performing a bed leveling calibration from the calibration menu after ensuring the nozzle tip is clean and free of any debris.
We also strongly recommend to keep the Bed Leveling Calibration option turned on when starting a print, for the highest chances of success.
