Replace the Plastic Nozzle

Before you begin the process of replacing your plastic nozzle, please note that your printer has a built-in utility which will walk you through the replacement process step by step.

  1. Select the menu icon from the dashboard.

  2. Select the Utilities tile from the available options.

  3. Select the Maintenance tile from the available options.

  4. Select the Replace Nozzles tile. 


  5. Select the Replace Plastic Nozzle tile. 


  6. Press the Unload Plastic button and follow the onscreen instructions.

  7. Use the 7mm torque wrench to remove the plastic nozzle, then press Next.

  8. Transfer the washer from the old nozzle to the new nozzle. Take care not to lose it.
  9. Apply a small amount of Anti-Seize to the end of the threads of the new nozzle, then press Next on the touchscreen.
    Note: Be sure not to get any of the Anti-Seize inside the nozzle.

  10. Select the Cool Head option on the touchscreen.
    Note: The print head will take five to seven minutes to completely cool.

  11. When the print head finishes cooling, press Next on the touchscreen.

  12. Using the torque wrench, screw the new nozzle partway into the print head, then unscrew it and screw it in again; this helps disperse the Anti-Seize over all of the threads. Press Next to continue with the utility.

  13. Once the print head finishes heating, tighten the nozzle until it clicks.
    Note: Be sure the torque wrench has solid contact at all points on the nozzle. Failure to do so may result in your plastic nozzle being stripped.

  14. Press the Reload Plastic button on the touchscreen.


  15. Select Meter Load and follow the onscreen instructions to reload plastic.

  16. Press Done to finish the utility.


  17. Run the Shim Bed Level utility (Menu > Bed Level > Shim Bed Level). For more information, see Level the Print Bed.
  18. Run the Bed Level Test Print utility to confirm that the bed is level (Menu > Utilities > Test Prints > Bed Level Test Print). For more information, see Bed Level Test Print
  19. If applicable, run the fiber nozzle height calibration utility (Menu > Bed Level > Adjust Fiber Nozzle Height). For more information, see Adjust Fiber Nozzle Height.
