Step 2 Tools necessary for this chapter

⬢For this chapter, please prepare:

⬢TX 8 Torx key

⬢2.5mm Allen key

⬢Wrench 13-16

⬢Universal wrench

⬢A cardboard box for use as a heatbed protection during the assembly. Hint: use the Prusament box.

⬢小さな真鍮ブラシノズル掃除用

Step 3 Preparing the printer

⬢Manually move the X-axis assembly all the way to the front side of the printer.

⬢Move the extruder approximately to the center of the X-axis.

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

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 4 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.

⬢On the printer screen, go to Control -> Temperature and set the nozzle temperature to 250°C.

⬢Wait at least 5 minutes. The remains of the filament must be warmed up slightly so that they can be removed more easily.

⬢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 5 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").

⬢Unplug the PSU cable.

Step 6 Disconnecting the hotend

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

⬢Disconnect the hotend thermistor cable.

Each connector has a safety latch. It is necessary to press the latch before disconnecting. Otherwise, the connector may get damaged.

⬢Disconnect the hotend heater cable.

⬢Leave both cables free for now.

Step 7 Removing the hotend

⬢Remove the x-carriage-cover from the X-carriage.

⬢Hold the hotend with your right hand.

⬢Using your left hand, insert the Torx TX 8 key all the way through the X-carriage until it reaches the grub screw in the extruder. Loosen the screw. Do not remove the screw, a few turns are enough!

⬢Carefully pull the hotend assembly out of the extruder.

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

Step 8 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.

⬢Manually release and remove the nozzle with nub from the hotend assembly.

Step 9 V6ノズルの取り付け：部品の準備

⬢For the following steps, please prepare:

⬢Nextruder V6ノズルアダプター（１個）

⬢V6 Nozzle (1x)

Step 10 Nextruder V6ノズルアダプターの取り付け

⬢ケーブルがある側から、PrusaNextruder V6ノズルアダプターをヒーターブロックにねじ込みます。

⬢ヒーターブロックを手で持ち、ユニバーサルレンチでPrusaNextruder V6ノズルアダプターを締めます。

⬢From the opposite side of the heaterblock, screw in the V6 nozzle. Do not tighten it completely. Leave a 2 - 3 mm gap between the nozzle and heaterblock.

The final tightening of the nozzle will proceed later. Please continue to the next step.

Step 11 Connecting the hotend

⬢Push the hotend cable behind the heatsink fan up to the electronics.

⬢Locate the hole in the heatsink from the bottom of the extruder and insert the hotend nub into the heatsink.

Do not tighten the grub screw to secure the hotend yet! Wait for the instruction.

⬢Connect the hotend heater to the upper slot on the electronics board.

⬢Connect the hotend thermistor to the lower slot on the electronics board.

⬢Keep the hotend assembly hanging on cables. Avoid to pulling on the hotend.

Step 12 Tightening the nozzle

次のステップでは、ノズルを加熱する必要があります。ホットエンドの熱い部分に触れないようにしてください。

Remove the cardboard box from the heatbed!

⬢電源コードをプリンタに差し込み、電源を入れます。

⬢On the printer screen, go to Control -> Temperature -> Nozzle Temperature and using the knob set 250°C.

WARNING: From now, the hotend and heatbed are very HOT. Do not touch these parts!!!

⬢スパナ 13-16 でヒーターブロックをつかみます。ホットエンドを引っ張らないようにしてください！

⬢Tighten the nozzle using the universal wrench. Do not overtighten it, you can damage the thread. Use the sufficient force. The prescribed tightening torque is 1.5 Nm.

NOTE: Avoid bending the hotend assembly while tightening! After that, there will be a gap of approximately 1 mm between the nozzle and the heater block.
