Do You have 2 physical nozzles or 1 nozzle with 2 extruder.

if it is 1 nozzle with 2 extruders, you need to check the shared heater box.

in the image you posted you have set the part to use the 2nd extruder( based on color)

if you only want to use the 2nd extruder, you need to make sure that the infill and support etc are set to use extruder 2 as well (by default they are assigned to extruder 1.)
