Cooling on Dual extrusion module

Dual Extrusion Head: Heat creep discussion thread

Hi folks, just finished a 6:45 hrs print with the DX (single color/left hotend), all stock + added locking blocks, but no thermal grease. No issues whatsoever. Print quality ranges from very good to excellent. I am particularly impressed by the handling of overhangs and bridges which came out very good (so print cooling is good!). After all, despite being one of the first receivers of the DX, I seem to be lucky and have a working device (pending that my right nozzle decides to act up on longer …

But be aware of the discussion following (and above) in that thread: it seems that the right nozzle has a cooling problem of a different kind.
