Is your nozzle temperature set to at least 180 degrees Celsius (can't remember the exact cutoff)? I think the ender 3 firmware tries to protect the user by not extruding as long as the nozzle temperature is not above a certain value.
I run Klipper firmware on this printer not stock Marlin. I usually print PLA at 210 so the temperature cut off wasn't the problem. I fully heated the nozzle before trying to extrude filament.
Hmmm try connecting the extruder motor wire to another movement motor (x, y or z) and running the extrusion to see if the movement motor moves. You could also connect a movement motor wire to the extruder motor and see if it extruded then
Ok so i swapped the extruder connection to the Z stepper one and it did spin! So the motor's not bad or the connection. Swapped it back to the extruder socket and nothing. So maybe its something in the Klipper config for the extruder?
