Octopus v1.1, e0 dont work

Good morning, I bought an octopus v1.1 mainboard, I configure the marlin normally but the motor connected to input E0 does not work, the status of the motor and the cable are fine, I checked it by connecting to other inputs on the card but the extruderdoes not work,My petg 3d printer filament cannot come out of the nozzle either I have looked for different sources and no solution works, when connecting the motor it does not rotate, but it does not vibrate either, the current connection of the extruder is in motor 4. Could you help me?
