Nozzle Replacement

Warning: Some operations require handling hot parts. Exercise maximum caution. Ensure that bed heating is disabled and that the door, bed, and other parts are safe to touch.

Procedure for Changing Nozzle

1. Heat the Hotend:
   • Heat the hotend to a temperature slightly lower than the printing temperature. For example, if printing at 300°C, heat the nozzle to 250°C.
2. Remove Old Nozzle:
   • Use 12 mm wrench to hold the hotend and 7 mm (9/32") wrench to unscrew the nozzle.
   • Unscrew the old nozzle, clear fittig plase from plastic remains
3. Attach new nozzle
   • Insert the new one, and tighten it with a torque of approximately 1.5 Nm (recommended by the manufacturer).

Procedure for Clearing Clogged Hotend or Nozzle

1. Remove nozzle:
   • Heat the hotend to a temperature slightly lower than the printing temperature.
   • Unscrew the nozzle. Use 12 mm wrench to hold the hotend and 7 mm (9/32") wrench to unscrew the nozzle.
2. Test Extrusion:
   • Attempt to extrude plastic without the nozzle. If the plastic extrudes, simply replace the nozzle.
3. Addressing Clogged Heat Break:
   • If plastic does not extrude, the heat break is clogged. Follow the procedure for Unclogging the Nozzle.
