Replacing a nozzle : before starting

Nozzles can be swapped in order to change nozzle diameter or material for special filaments or to change an old nozzle with a new one.
Regardless of the reason and the modle of the head the procedure requires the following conditions:

  • Remove the filament from the nozzle by unloading the filament
  • Remove the head while the unit is idle and the nozzle is cold.
