in this video I'm showing 2 problems, (1) leaked PLA around the nozzle, (2) irregular output (irregular extrusion speed and filament diameter). I'm trying to maintain my beloved 3d printer by cleaning the thermal barrier, creating a blob, testing the nozzle diamater, obviously something physically bothers the extrusion speed, and it's located at the bottom of the nozzle, and I've also noticed that the orange paste around the nozzle has partially disappeared and has burnt, maybe it has created excessive heat in the mecanism... don't know. Now : what could I do ?
