I've replaced practically everything: nozzle, extruder gears, extruder motor, printhead circuit board, tightened the belt, calibrated the extruder, calibrated the pressure, PID, changed/dried the filament, tried printing slower, faster, what do you think it could be?

Ender 3v3 (no-Ke/SE the mini version of the 3v3 Plus)

Is a Direct Drive Extruder with metal gear (solid ?) instead the plastic ones
