Agree with Stefan - reinstall the (2) M6 x 12 cap head screws removed in step 22. You do not need the (2) M6 x 16 cap head screws at all, nor do you need to reinstall the washers from step 22.
IMPORTANT To followup on Seppo's comment in a previous step - the arms did not come with heat inserts in them as shown. I didn't realize this until way later (installing the felt wipers in the Accessories section, where it is more difficult).
I needed to install (2) M3 heat inserts in each arm. Do this now vs waiting! It's not called out anywhere else.
The rear M5x85 Screw kept falling while trying to mount the motor assembly to the frame. I ended up using some masking (painter's) tape to prevent it from falling down. Worked well.
The timing pulley is aligned 'gears down' in this picture, but in the left stepper motor assembly section that one is 'gears up'. Unsure if this is indicated correctly or one of them will be fixed in a future step...noting this here.
These ball bearings (3 - the 2 flanged and 1 unflanged) are the 'idler pulley's'. If you purchased the heavy duty idler pulley's (add-on / option) then one heavy duty idler pulley replaces these 3 bearings. Better to add them now if you bought them. And this follows through the rest of the build.
"Route the power cable back to the electronics enclosure and follow the piano wire previously installed." - this is the first reference in this guide about piano wire, not sure where it was instructed to install it.
Similar to step 23 (spool arm), the M6x16 is too long. I reused the M6x12 without the washer to screw the lower corner bracket assembly into the base.

I also had to file down 2 inserts on the left tensioner. Not my favorite thing.

This is the:
Coupler Rigid Type BLK
SKU: HW2990GC
(I believe)
Based on Electronics section 12. Electronics the grommet on the rear panel should be on the LEFT. It's not clear from this diagram.
