1. My kit included 2 X-idler brackets. One of them was the old style. The second one was the new style and had the cutout needed for the improved Z-stop adjust system. 50/50 chance, and I installed the wrong one! So watch out for this.
2. There are 2 M5 nuts that fasten the large gear in the extruder to the hobbed bolt. Both of them were half-height jam nuts in my kit. You will have better success if the nut that fits into the trap on the gear is a full-height, standard M5 nut. The half-height nut doesn't stick out of the trap, so the jam nut did not ride up snug to it. This will make more sense when you get to that spot.
I think you will love your printer, and the whole build experience!
