petg jam in hotend heatbreak
hi,
A few times in a row my printer prints "the air" filament doesn't come out of the nozzle. It is stuck, don't move down to the hot end neither up when trying to unload it. I disassembled the extruder and I see that a clog is in the heatbreak,
when I pull out the stuck filament of heatbreak some of the filament still remains on the heatbreak walls. I put noozle temperature to 280c, filament should melt but it does not. Where is the problem? Maybe hotend is not working properly and don't raise temperature till 280c and that's why filament don't melt from the walls?
