Hello there! I recently bought a 3d printer for the first time, a PrimaCreator P120. Today I was going to change filament, because there where very little left of the old one. But I accidentally broke of the filament and somehow managed to push it when I tried to grasp the small part that was left. So now it is inside the tube, and I cannot get it. So I tried pushing it further using the new filament and by heating up the nozzle. Unfortunately I can't get it out. The new filament won't move at all. So I now plead with anyone of you for help, and would appreciate it a lot.
