it won’t be a match because the drag chain is 3D printed and the connections for it are on the sides of the chain, not an extension at the end, but I can print a new one to match. This will work.
My solution was to use the ends of the tubes, and install plugs in them.
These plugs go into the ends of the gantry tubes. You can see there are openings for the wires to pass through. The holes near the plugs are for rag chain mounts. The box piece top lefta mounts to the core clamp, and holds the drag chain end at the router. This ttaches to the core, so it does not have any pull on the Z tower at all.
You mentioned the z tower pull on the other thread. Thank you for sharing the solution you use.
