I have an Ane5 a6 printer. It worked really well for about two weeks, but now I get a very uneven flow in my prints. Any ideas what may cause this?

Solution:

Thanks for the feedback. It did look like under-extrusion.

The Net A6 comes partly assambled by the manufacturer. One issue that sometimes occurs is that the gear in the extruder-head, that feeds the filament into the extruder, is not fastened as it should be. The prints are good in the beginning, but over time, the screws come loose and the gear moves over to the side. It then loosens its grip on the filament and cannot push it into the extruder head. It can easily be solved by removing the fan, fastening the screws inside and reattaching the fan. The printer now works great again.
