I would advise fitting the ‘Y drag chain moving end mount’ onto the X axis endplate before assembling to the C - beam.  I found that it is very difficult to get an alan key on the head of the rear bolt and turn it for tightening.  There just not enough room in between the beams.  Either that or use tapped holes in the X axis end plate and fix the ‘Y drag chain moving end mount’ with low profile M5 screws from the outside ( do away with the nyloc nuts).

I found that there is not much room to fit in the clamping collar and flexible coupling on the Y axis drives.  The flexible coupling is pushed right up against the motor meaning that the grub screw is past the flat on the motor shaft.  It seems to function ok but could probably do with 5mm longer bolts and spacers to be on the safe side.

I have the same issue with the cap head bolt on the locking collar fouling the Z axis plate.
