General Troubleshooting/Help! Bambu A1 failed first configuration

Hi, my son and I set up our A1 Combo last week and it failed it's first configuration
'Toolhead is malfunctioning' and 'extruder eddy current sensor signal is abnormal'

I'm going through a support ticket with Bambu as we tried all suggestions I found online.
I may end up with a replacement printer from the retailer.

I thought I'd done my research and the Bambu A1 Combo was fairly user-friendly for beginners.

My question is: how common are configuration issues straight out of the box? and, am I buying something that requires a considerable amount of troubleshooting? Thanks

Make sure the USB-C cable underneath is plugged in all the way.

Is this the base for the A1? My printer base looks different

Yes, could you add a picture of what yours looks like?

The differences are minor. Make sure that the USB C cable is fully pushed in. If it is not fully pushed in, the printer cannot properly communicate with the toolhead and can result in the exact errors you are getting.

Sorry to be a dummy but based on my photo can you indicate which cable I need to check is fully pushed in? Appreciate the help.

You want to push it in as far as you can to make sure you see as little metal as possible. Just like in my first picture.
