Hi, I have received the CubeX Duo too. The first jet with White ABS and the second jet with Red PLA. I can say that I have the same problems. In case I only use PLA, the quality is aceptable but if I use ABS, the results are far away from expected. I have used before the Afinia UP and iit's results are better than CubeX. The only problem for this 3d printer is that it has a very limited printable area. I would appreciate if anyone could send it's setup data for comparing them with mine ones. Thanks. Miguel Angel.
