About 5 hours into a print last night, the filament stopped extruding leaving the model unfinished.
On investigation, I saw that the filament had stopped feeding. I can see marks on the filament left by the wheel that feeds it through the tube. The marks stop with a black mark. Does the black mark suggest a reason why the printer stopped printing?
I am using an Anycubic Mega S with 3dJake EcoPLA.
