e) Nozzle change

  Caution: Danger of burns. Do not directly touch the hot nozzle or the extruder.

•  To replace the extruder nozzle, the extruder must first be heated to a temperature suitable for the inserted filament material.
•  When the temperature is reached, remove the inserted filament material as described in chapter "15. c) Removing and changing the fila

-

ment".

•  Screw off the extruder nozzle (1) from the extruder with an 8 mm hexagon wrench or ring spanner (2). Alternatively, you can also use an 8 

mm hexagon socket wrench for this. This way, the nozzle cannot fall off.

  When unscrewing the nozzle, always secure the extruder against twisting at the heating block with an 11 mm hexagon socket wrench (3).
  Never damage the line for the temperature sensor. This may lead to short circuit otherwise. Loss of guarantee/warranty!

 The extruder must not twist during nozzle change and the nozzle must never be turned when cold since the extruder may 

otherwise be damaged and rendered useless.

•  If necessary, clean the thread of the heating block carefully with tweezers or flat pliers.
•  Apply PTFE sealing tape to the new nozzle. Observe the winding direction in any case! The sealing tape must run with the thread! This means 

that the end of the sealing tape on the outside must not oppose the turn-in direction. Otherwise, it may happen that the sealing tape is moved 

when turning in and will not seal properly (see small picture on the left).

  The sealing tape must never protrude beyond the thread. The sealing tape that protrudes beyond the thread, cut it off with a sharp knife. 

Smooth the sealing tape well with your fingers. The ridges of the thread may be slightly visible. This way, the nozzle can be turned in more 

easily without the sealing tape becoming bunched up in the thread (see small picture on the right).

  For this, observe chapter "13. b) Assembly of the extruder " in the assembly instructions of the RF2000 v2 construction kit.

•  Screw the new extruder nozzle carefully into the heating block and tighten it again (do not forget to secure the heating block!). Never apply 

any strong forces for this.

•  Then put in the filament again as described in chapter "15. Inserting, removing and changing the filament".
•  Switch off the extruder heating again and have the extruder cool off.
