Pro-Plan

After changing Filament from PLA to ABS everything was ok. But after changing back from ABS to PLA printing failed. At first, still some material came out of the nozzel producing a cobweb type formation only. Then no material at all was printed. After cleaning the nozzel (atomic-methode) the nozzel seem to be clean, but still no material is deposited. We noticed a deep groove in the filament at the position of the filament feeder.
