Benefits of the upgraded nozzle and hotend:
- The longer nozzle thread helps more efficient filament heating
- The new heatbreak prevent the melted plastic to go up to the cool area and clog there
- The new cover on the heatblock helps to keep the nozzle temperature more stable (ex, when the object fan starts the temperature will not drop)
- To assemble the nozzle, it is not necessary to heat the heatblock and heatbreak.
