@a2iink probably, your Z endstop is too high.

@a2iink wich is your machine? Could you send some photos?

@BaDboD I have not sanded the bed. I understand that since there is an alternative that works for me without doing work, that should be the option. I have set the bed to 110 which is what my ender3 pro gives. I have spoken with a maker in my environment and they have had problems with the PEI bed, I will not use it. The piece always ends up coming loose and I have not managed to make a complete impression.

@BaDboD the problem persists. I will use the black one again, because it has never given me problems.

@BaDboD about z problem. I had the same problem some times. I had solved It Playing with noozle and bed temperature, increase 10°c noozle, and later can put your normal work temperature. Expect than this can help you.

@BaDboD Hi, thanks for your consideration. Bed level or temperature is not a problem. I am working ABS, without problems using the Flex magnetic bed, but creality PEI have made this adhesion problems. Will Clean It as you have said expecting that solve. Thanks a lot.

I have purchased a PEI bed for my Ender 3 pro. The pieces come off the bed, which is not the case with the standard bed. Any probable reason?

Hi, is ABS filament avaliable ti work with ender 3-Pro?. I have seen that yes in web information, but documents only say PLA.
