After reading the instructions more carefully, it says to lightly hook the cowling hole around the tip BEFORE installing the screws on the side where the fan gets mounted. After this photo was taken, I undid the screws and slid the cowling to the left, hooking it carefully over the extruder tip, and then it all fit fine. Lesson learned about reading instructions fully and carefully.
The springs are a holdover from the original model Ecksbot, that aren’t required for the 201q4 model, but they got installed later on the Y axis anyway.
The parts in this bag are the extruder cleaning rod (long copper one), the tiny extruder tip cleaning pin, and the balck plastic L shaped piece is used to square everything up during the calibration phase.
