We will always inform you when instruction steps involve handling hot parts.

Take care when working on parts that are heated.

Avoid touching hot parts!

While the nozzle is heated and placed on the heatbed (carboard box), DO NOT leave the printer!

Step 3 Tools necessary for this chapter

⬢For this chapter, please prepare:

⬢T8 Torx key

⬢2.5 mm Allen key

⬢Universal wrench

⬢Wrench 13-16

⬢Nextruder box as a heatbed cover.

⬢小さな真鍮ブラシノズル掃除用

Step 4 Select the tool

⬢On your printer, go to Control -> Pick/Park tool.

⬢Select the tool on which you wish to install the V6 Nozzle Adapter.

We'll use "Pick Tool 1" as an example.

Step 5 Filament unloading

⬢If you have loaded the filament, unload it from the hotend. On the screen, navigate to Filament -> Unload Filament.

⬢Select the tool that you picked in the previous step.

The selected tool will automatically move to the front of the printer.

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!

⬢Remove the filament from the hotend. It is not necessary to completely remove it from the printer. Just a few centimeters (inches) above the extruder.

Step 6 Cleaning the hotend

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!

次のステップでは、ヒーターブロックとホットエンドをフィラメントゴミからきれいにしておく必要があります。そうしないと、ノズルを外すのが難しくなります。

If you have a Prusa hotend sock on the hotend, remove it.

⬢真鍮のブラシを使い、ヒーターブロックとホットエンドのフィラメント汚れを注意深く清掃します。ショートする恐れがあるため、ブラシがホットエンドケーブルに接触しないようにしてください。

⬢When the heaterblock and the hotend are perfectly clean, cool down the printer. On the screen, navigate to Preheat -> Cooldown.

Wait until the hot parts are cooled down to ambient temperature. It takes approximately 10 minutes.

Step 7 Park the tool

⬢On your printer, go to Control -> Pick/Park tool.

⬢Select Park Current Tool.

Step 8 Preparing the printer

Before you proceed, it is recommended to protect the heatbed.

⬢Make sure the heatbed is cooled down to ambient temperature. Place the empty cardboard box approximately to the front center part of the heatbed.

⬢From the rear side of the printer, turn the power switch OFF (symbol "O").

Step 9 Undocking the Nextruder

⬢On the selected, cleaned tool:

⬢Gently undock the Nextruder.

⬢Put the Nextruder on the heatbed.

Step 10 Disconnecting the hotend

⬢Open the dwarf-cover-door to access the electronics board.

⬢By pressing the safety latch, disconnect the hotend thermistor cable.

⬢By pressing the safety latch, disconnect the hotend heater cable.

⬢Leave both cables free for now.

Step 11 Removing the hotend

⬢Insert the TX8 Torx key all the way through the tool-changer until it reaches the grub screw in the Nextruder. Loosen the screw. Do not remove the screw, a few turns are enough!

⬢Carefully pull the hotend assembly out of the Nextruder.

⬢At the same time push the hotend cables behind the fan out of the Nextruder.

Step 12 Prusaノズルの取り外し

⬢Using the 13mm cutout in Universal wrench X grasp the heaterblock.

⬢Using the 7mm cutout in the Universal wrench Y grasp the nozzle and loosen it.
