@admin i purchased the quiet 32bit Creality upgrade card for my ender 3 pro. After installation it ran a test print fine with the upgraded software. the next day however, it does not even start to print and halts with "Autohome failed". I have removed all of the card connections and remade them but still the same fault. I have triple checked the wiring and no issues. Please advise.
