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 extruder does 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?
I have not used the btt octopus board. I believe it can address several extruders. Are you connected to the one programmed in marlin?

I think in Marlin, you have to override the cold extrusion limit to get the extruder to move when not above 170C at the hotend.
Also, Marlin will reassign the Ex ports depending on whether X2, Y2, or Z2-4 are used.
I hope this helps, moved on to Klipper a long time ago.
thanks all you guys,it works now!
