What about a brass brush for wiping the ooze (instead of capton tape). The guy from the channel Design Prototype Test implemented successfully a brass brush wipe on an ender 3. Check it out :)
Very nice job! Personally I do not trust just magnets. I would be afraid that print head will pop off when it hits a bump in print. I would add a servo-controlled locking mechanism so that print head is securely locked to carriage. Also for positioning you use screws - very nice idea but is locating head precise enough? Is there no play between screws and the holes they go into? Maybe conical shaped pins and holes instead so that there is no play on the position once head is pulled in by magnets. To account for differences in hot end length you could have an adjustment screw between the part that has magnets and locating holes and part that holds hot end. Sliding up and down as you rotate screw. Then you could adjust height offset of each hot end individually. Just my thoughts.
Nice setup btw. I am still undecided on which corexy to build. After seeing your EVA system, I know I want that setup with the gantry. It looks gorgeous and cleverly designed. For a 360-400mm build surface, do you have any suggestions between HEVO, hypercube or RatRig v-core (I discard voron because I want the EVA system)

@@eva-3d948 thanks a lot for the information! Indeed, ratrig is looking more and more attractive.
