Hello all, Need your assistance with some problems I am having with Ultimaker 3 printer. For a while now I am having problems printing with PLA black with my ultimaker 3 printer, each time I start a new job the print core gets clogged at the very beginning. Because of that i tried to use ABS black, if I print a short job (2-3 hours) it comes out ok but if I print a long job like the one with the attached pictures the print core gets clogged also with the ABS. Does anyone know what is the reason with these issues with both materials? attached are also the Cura parameters for both materials. All materials are original and being recognized by nfc chip plus i did hot and cold pulls to the problematic print core. tnx
