The part of the PVA which has passed the feeder was brittle, but the filament before was not brittle.
The Atlas has a diameter of 2.86 mm, PVA 2.88 mm.
I see the main diference that the PVA has a smoother (less rough) surface, especially after running through the feeder
I am using a unit with a vaccum pump and hot sealing, as you use it before deep-freezing food.
Hence I did not use silica bags, or do have I?
I think that is quite likely. 15 months is pretty old. Is it brittle when you try to bend it?
I am not familiar with this material, but if this would be the case I think it would be more accurate to say the filament would be too thick.
Besides keeping filament in a vaccuum bag, do you also keep silica bags in the same bag?
