Extrusion stops during print I changed the filament (PLA) in my Wanhao Duplicator I3+. I ended the first try to print when I saw that the 'lines' were too thin. I re-sliced with a higher temperature (195°C instead of 190°C). Now the print started without a problem but after about 25% no more filament came out of the extruder. What can be the reason and how can I resolve it? The filament is from Vertex, grey. The object that I use to test is a 20 mm hollow cube from Thingiverse that I have used for the previous filament too. I am not sure that this is a clogging problem since the print starts with no problems. It just stopped after 25%. When I started another print I was able to finish by increasing the temperature.

I redid the print in order to reply to some questions posed in the answer of @kdtop. The print started but the output was not consistent and sometimes stopped. The temperature is 195°C and sometimes 'drop' to 194°C. First I pushed the new real so that the extruder did not need to pull so much. When this did not solve the problem I changed the temperature to 200°C. Now the output became consistent and my print finished. It was not as good as the one that I did with my previous filament. The top was not as neatly closed. Only the last 2 layers covered more or less for 100% the surface (perhaps 200°C is too high for this?).

For me the solution is to higher the temperature to 200°C (or perhaps 205°C).
