Brittle prints

[Nielski55 0]

So i got this new roll of pla from Real. It prints pretty good overall. But it latly my prints became quite brittlr. Especially the suports and infill. Sides were fine. It seems to be due to the temperature in my printer case. When the doors were closed it printed brittle but when open the lines became solid again. Is there anyone who can confirm or knows why this migjt hapens? Thanks

I have an Anet A6

Could be also under extrusion. For your Anet A6 I found this, maybe this is also the root cause for your problem:

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.

Yes i red this too. If it keeps hapening even with the doors open i will try that. But for now it is printing fine, only when it becomes to warm it seems to be happening
