ERROR: KEY 2529 Leveling sensor chip abnormality

I have owned my K1 MAX for almost two months now and it was working perfectly until this week. I started getting ERROR: KEY 2529, I have tried bed leveling with no success… i’m not sure what to do now. The error is consistent and now will not print due to this error,


any help would be greatly appreciated.

Tive esse problema quase agora amigo, apenas resetei ela para o padrão de fabrica, e voltou ao normal.

Had the same error, did as suggested in this post and did a factory reset. It seems to be working now.

UPDATE: After factory reset, and a print, got the same error again. Printer is only 2 weeks old (very discouraging). I found the following documentation

In it, it mentions to loosen the screws on the bed appropriately, I loosened them, to just be snug, and it is working again.
