We recently changed the Filament from Ultimaker PLA White to Ultimaker PLA Silver metallic. The print shown in the pictures is the first print after the material change, it shows signs of underextrusion that didn't occur with the white PLA Filament. We removed the Material out of the Bowden-Tube and saw the scratch marks that produced by the Feeder which wasn't the case before. I would like to know if anyone knows what the problem could be or has some ideas.
