Check carefully where the zip ties are being placed on the VAOC camera cable. On my assembly, the camera cable has full insulation, then shrink tubing, then individual wires, and the natural fit put one zip-tie on the individual wires and the other zip-tie on the shrink tubing.
When tightened, this caused abrasion of the individual wires, and damage to the insulation on one wire.
Check the the placement of this cable to ensure that the zipties are both holding the shrink tubing, or consider using electrical tape or perhaps more shrink tubing to provide a more even grip on the cable.
This appears to have changed from previous versions (hence 'check your cables'). I'd like to suggest the wire colors should match the pinout for the EBB42 Endstop -- that seems higher priority that wire colors for a microswitch.
I'm not sure where it would go, but some statement in the commissioning guide of 'if your EBB42 crashes/shorts when the endstop is triggered/released, check the endstop wiring' would have been appreciated.
I would suggest this diagram and the text should call out the difference between the male and female crimp connectors in a larger diagram. (My kit supplied 4x of both kinds of connectors in a single bag, and a builder unfamiliar with micro-fit might not notice the difference.)
As with Step 72, this step can be performed before the fan is mounted to the x-rail (and would be much easier, as the rail is in the way once it is mounted.)
I'd suggest that the builder should check the position of the "flat" on the stepper motor, at this step, and confirm it is on a side within the printer volume. The position shown in diagram #1 (red) should be ok, but it might be better to position it towards the front of the printer.
Making sure the "flat" is aimed towards the builder will help tighten one grub screw on the pulley to the flat, as mentioned in a comment to Step 4 of guide 9: Gantry Alignment.
I ran into a clearance issue: I cannot bring the X-axis gantry forward all the way because the joiners collide with the tensioner arms.
If the tensioner arms should not be colliding with the joiners prior to tensioning, then I suggest Step 27 of the the Motion System instructions should provide guidelines for an acceptable position for the tensioner arms. They seem to need about ~25mm maximum protrusion to avoid collision at this step. (Perhaps a more specific position is desirable based on the expected amount of positive/negative adjustment that will be needed.)

Should this start with "If your back panel..."?
(I wound up with a Batch 1 kit/bottom plate, and Batch 2 enclosure panels, so don't have either hole, oops.)
Shouldn't there also be 4x M2.5 Heat Inserts to match the 4x M2.5CHS for the Raspberry Pi brackets?

Clearer details on exactly how the USB cable is routed around the zip tie mounts would be appreciated.
Same comment as on step 18: make sure the "flat" on the stepper motor is accessible, for later fastening of the pulley.
