  5. Select the Temperature Control tile from the available options.



  6. Select the Heat option on the screen when prompted.



  7. Select the Fiber option on the screen when prompted.



  8. Press Done to exit from the manual heating utility. The nozzle will continue to warm up until it reaches operating temperature.



  9. When the nozzle is heated, use the 10mm torque wrench to loosen the fiber nozzle.
    Note: Do not remove the fiber nozzle at this point. Just ensure that it is able to turn somewhat freely. Do not touch the nozzle with your hands, as it will be very hot.
  10. Repeat steps 2-5 to navigate to the temperature control settings, then select the Cool option to cool the fiber nozzle.
  11. When the nozzle is at room temperature, remove it from the print head with your fingers or the torque wrench.

Replace the Fiber Nozzle

  1. Insert the Teflon PTFE tube into the replacement nozzle.



  2. Apply a small amount of Anti-Seize to the end of the threads of the nozzle.



  3. Using the torque wrench, screw the new nozzle into the print head but do not fully tighten it.
  4. Unscrew the new nozzle and then screw it partway into the print head again. This helps to disperse the Anti-Seize over all of the threads.
  5. Tighten the nozzle until it clicks. 
    Note: You do not need to heat the print head up again to install the new fiber nozzle.
