  • Heat the composite extruder up to 200C° . Using the 9 mm socket wrench unscrew the composite nozzle from the composite extruder – turn it clockwise, do not use too much force to avoid damage of the composite nozzle
  • Check the сomposite nozzle, there should be no fiber pieces inside. If they are there, remove them with tweezers.
  • Heat composite extruder up to 250C°. Clean the guide tube in composite heater block with cleaning needle from tool kit or you can use any stiff steel wire with 0.8 diameter.

Caution!
