Does anyone know what Error 2404 Unknown Exception means and how to cure it? It appears to be something to do with WLAN printing. I have a new CR-10SE and it shows this error whenever I send a file to print. The print seems to be OK and the machine is working fine. I’d just like to know how to avoid this error in future.
It’s not in the Wiki. Contact them to update the Wiki please.

I have done so. The LCD actually povided more details and it is to do with the Y belt tension not being high enough or/and the y post not being tight enough. I tightened both and still get the error which support says not to worry about. It is something to do with what happens when the unti switches off.
The Y endstop is probably loose.
