Printing keep clogging and failing

While trying to pring the prusa enclosure version 2 top corner pieces i experience constant failures and bad print quality.  I can get a perfect first layer and after a while i get cloging or bad extrusion and the print starts to break down due to these rundom clogs. I have tried several different adjustments, speed reduction, profiles calibrations end so on but the damn thing keeps doing the same. I have 50 to 45% humidity with a humidifier running, tried different temperatures for my petg and different petg packages from prusament all with themsame results. When i pring this large surface the print progressively breaks down. Can anyone help me out? I am beggining to regret not going with the zortrax cause i seem to spend half of my printing time debugging the damn thing.

Hi Koutso, 

Have you tried reducing the retractions to say 0.4mm?

After doing some research i found out that this was due to extruder clogging. I did the cold extrusion cleaning method and the problem was resolved.
