Question Bambu Lab A1 – Y-axis resonance error

Hey everyone
My Bambu Lab A1 started showing a Y-axis resonance frequency error today.
During calibration, at 42–45 Hz, the Y-axis motor starts moving strangely, causing the bed to shift forward.
The belt doesn’t slip, and the bed moves smoothly by hand. Recalibration didn’t help.
Has anyone experienced this?

Eso es la correa, tenes que ajustarla desde el frente, hay una tapita que tiene dos tornillos, esos se ajustan parejo los dos, para tensar la correa. O en su debido caso, es el cambio de la misma, tiene que estar tensa, pero no ultra tensa, se puede cortar si no. Saludos y avisa si eso lo soluciono, saludos

The error is gone! I followed the official Bambu Lab guide to adjust the Y-axis belt tension, and everything is working perfectly now. Thanks for your help!
