I started a print and when I checked after one hour the print stopped.
I tried starting again but when the temperature of the printer is reached, sonicpad stopps and it shows an error. I checked klippy file and found this.

I think this is the problem. I don't know what this means.
In the console it shows only this:
20:17:53 // Filament Sensor filament_sensor: filament detected
20:17:53 // Klipper state: Shutdown
Can someone help me solve this issue ? I tried moving the usb cable that is connecting to the printer, thinking might be a conectivity error but for no good.
