K8400 doesn't start from home position anymore

My K8400 printer doesn’t start from and return to its home-position anymore. It prints fine otherwise but the prints seem to start to far out in x and y direction to be able to use the full build volume. I can manually force the extruder in the home position but even then it’ll move in the y direction a bit.

Also when replacing filament it’ll bump into the front of the printer and stays there.

I tried resetting the printer to its factory settings but otherwise I don’t know where to start to solve this

Hello !
An endstop issue ? ( To check, if you manage to connect via USB, look the “Endstop States” ( M119 : Endstop States | Marlin Firmware ) before and after a Home ( G28 ) )
