Ultimaker 2+ still has the same problem, I cannot use it any more - 6 months after purchase. Filament moves slower out of the nozzle than it is pushed into the tube. See above. According to devices here, I have made atomic pull about 10 times all together, i have replaced the teflon coupler (22EUR), I have replaced the nozzle (0.4 into 0.6), all this took me several days and it still does not work. I wanted to use the 3D printer for a teaching project at the university and for a master thesis, it is not the best advertisement if I am stuck here. There is already a delay. Wikth this experience, I would not want to buy a new one even if we had the money for it. (I do not have the full understanding whether officials from Ultimaker read these messages, if yes, the latter message is for them). Today I will ask for gurantee / replacement at Conrad electronics in Germany, where it was bought.

Thank you, I know now what I can do next. In case I find out that I need a new teflon coupler, does it look like this? Its termed 3D Solex TFN PTFE Coupler UM2+.

thanks, I may need to replace this part, I have already made atomic cleaning, tried lower print speed, elevated temperature, always same problems. 4 models were printed half then print was interrupted and the filament curled behind the printer so the picture does not look the same as my printer (ultimaker 2+) what is the part called? where can I get it ?

After ca 100 3D objects the filament extrusion slowed down. The transport at the other side of the tube is faster, as a result, the tube goes off, printing is discontinued. This is getting harder, elevated temperature did not help (Ultimaker 2+, transparent PLA)
