The extruder printed cover is placed over the extruder in order to give protection to the extruder cable and all the cables plugged into the extruder PCB. The cover secures the extruder PCB on the extruder aluminum cover as well as functions as a distance piece between these two components. Therefore, if you notice visible signs of wear and tear on the extruder printed cover (cracks or breaks), replace the cover to avoid any kind of failures.
At first, print the cover and then replace it according to this manual. The model is available for download here.
