On step 9.8 it says "8. Grab 2x part XX (used only for alignment) and place on the printer as shown." Which part is that? I don't see it shown in the pictures.
Step 9: Adding Right Idler Bracket
8. Grab 2x part XX (used only for alignment) and place on the printer as shown. Note the tabs on the top of the plastic corner piece which should hold the extrusions in place.

Here is a second build question on "Step 11: Adding Motor Pulleys". How far from the top of the motor shaft should the GT2 pulleys be mounted?
Thanks

SOrry about that! I'll fix the instructions soon. For the alignment, you just use the plastic corner blocks that will eventually be going there. You temporarily place them where they will go in order to align the height of that intermediate extrusion ring. And you will have to adjust the height of the pulleys according to how the belt sits but about 2mm below the top of the motor shaft is usually about right.

Are the plastic corner blocks you referring to the Rod Brackets A9-12? For the 2mm measurement for the pulley height 2x D15 (M5 Washers) would do the job nicely as temporary measurement spacers on the top of the pulley. I will hold off with the blue lock-tight until the exact height adjustment is made. Thanks

Those are the ones and yeah definitely wait until you get the full printer built and can see that the pulleys are at the right height before using loctite! Let me know if you have any other questions on the build! -Andrew

Step 11: Adding Motor Pulleys -
3. Repeat the process for the other stepper motor, but take note that on the right side, part G10 is installed "upside down" compared to the left side. Again, leave about 1mm of the shaft exposed and Blue Loctite is recommended on the grub screws.
So for this step the right-hand photo should show the pulley mounted "upside down" correct?

Upside-down compared to the left side, yes. So on the left side, the grub screws will be above the teeth of the pulley, and on the right side the grub screws will be below the teeth.

I'm not sure exactly what you're referring to, could you be a little more specific?

I only see 3 there but maybe I'm missing something. Regardless I wouldn't worry about that, you only need 3 (1 for endstop, 1 for wire bundle clamp, 1 for pfte clamp)

Step 14: Y Slider Assembly Part B
It says this:
1. Assemble the four idler stacks. The top two are identical and the bottom two are identical. The top two use parts D14 as the base bolt. Notice the error, there should be 2x part D15 above the two bearings (G11) and 3x part D15 below. The top two idlers use parts D12 as the base bolt and have 2x part G11 for the idler and 1x part D15 below.
I believe the last sentence should says this:
The bottom two idlers use parts D12 as the base bolt and have 2x part G11 for the idler and 1x part D15 below.
Thanks
