I have removed the left extruder and set my flashforge to one extruder in the settings, My quality of the printed parts has vastly increased due to the 2nd nozzle not dragging over the part. If I need to dual extrude I have ordered a quick connector that I am going to mount on the back and create a loom so I can plug it in again and dual extrude in about 5-10 minutes.
Its also much easier to level the print bed.
