I agree the new part on the extruder is intended to prevent cable breakage, but the official description for the Rambo changes sounds more like they are trying to address complaints about the difficulties assembling it.
I would need to see the printer in action with the new top-exit of the extruder cable bundle to be certain, but I think that the relocation actually tightens the radius of the bend in the cable bundle. I cannot 'simulate' it well enough in my mind to be certain, but I think it might make cable bending worse.
I'll leave the Rambo enclosure unchanged for now, but I will extend the extruder cable bundle length as long as possible (limited by the shortest cable in the bundle). I have already added a nail at the Rambo end, shrink-wrapped to the end of the 3mm filament, to stiffen the bundle at the entry point into the Rambo housing.
Looks to me like I can get started with the upgrade tomorrow, fixing the cable breakage issues. I'll probably leave the rest of the upgrade kit lying around (once it actually arrives) for spare parts if the bearings start causing trouble one day.
