⬢The bag with fasteners includes two M3x20 screws needed later, separate them now to avoid using them instead of M3x18!

⬢Keep the magnets apart in a sufficient distance. They can break each other!

⬢MK2.5S用のホットエンドは、MK2.5に比べて短いPTFEチューブを使っています（詳しくはPTFEチューブのトリミング方法 - Original Prusa プリンター）。チューブを交換したか、ご確認してください。

⬢Pay great attention to the cable management, if you miss some important step you would need to disassemble the extruder.

⬢This bag includes extra fasteners. Don't worry if you finish with few unused screws and nuts.

⬢Take two M3nS nuts and insert them in the Extruder-body.

Ensure correct alignment using the Allen key.

⬢Secure the nut using an M3x10 screw. Tighten the screw just slightly, later on we need to add the P.I.N.D.A. sensor.

⬢Take two M3n nuts and insert them in.

Use the screw pulling technique.

⬢Take the smaller magnet (10x6x2) and insert it carefully in the FS-lever. Majority of the magnet will be hidden inside the printed part.

⬢Insert the FS-lever in the body.

⬢Secure the part with a M3x18. Tighten it, but ensure the lever can move freely.

⬢Insert the bigger magnet (20x6x2) in the Extruder-body, it will stick out:

⬢Take the printed part Adapter-printer and insert the steel ball in.

⬢Roll with the ball to all sides to ensure smooth movement.

In case of any rough surface, remove the ball and clean the inside of the printed part.

⬢Place the printer part together with the steel ball in the Extruder-body. The surfaces of both parts should be almost aligned.

⬢Extruder motor (1x)

⬢Extruder-motor-plate (1x)

⬢M3x10 screw (2x)

⬢Take the Extruder-motor-plate and secure it using two M3x10 screws. Use the cable as a guide to properly orient the part.

⬢Resist the temptation to place a screw in the third hole! Leave it for later ;)

⬢Rotate the shaft as in the picture. Flat part must in the direction of the arrow.

⬢Slide the gear on the shaft, the lock screw must be facing against the flat part of the shaft. Tighten the screw slightly.

⬢There is a "channel" for the filament inside the printed part. Align approximately the teeth on the gear with it.

⬢Don't tighten the screw just yet. We will align it properly first. See the next step.

⬢Take a piece of the 1.75 filament. You can use the bundled one on a spool, don't use the black nylon, which is too thick. Straighten the filament as much as possible.

⬢Place the filament along the path and align the gear properly.

⬢The filament will be always slightly bent. Use it anyway for the initial alignment.

⬢For a final check replace the filament with an Allen key. Bear in mind, the key has slightly different size than the filament.

⬢Tighten the screw if needed, we will make the final check later on.

Don't use any glue to fix the screw in place, you won't be able to release it, in such case you might have to replace the entire motor.

⬢Extruder-cover (1x)

⬢このガイドでは、返品や修理のため、組立済プリンタの梱包箱を使用しプリンタを梱包する方法について説明します。

⬢Slide the nut all the way in.

Ensure correct alignment using the Allen key.

⬢Leave the second slot empty, we will use it later.

⬢Hotend for MK2.5S (1x)

⬢M3x40 screw (2x)

⬢M3x10 screw (2x)

We will use some screws later, but keep them around.

⬢Take two M3x10 screws and insert them in the holes. Doing this now makes the assembly slightly easier, but both holes are shallow and the screws might fall out. If this happens, you can continue without them and put them back later on (you will be noticed). Also note, that in few upcoming pictures the screws might be missing.

Hotend assembly was completely reworked from MK3 to avoid bad placement. Also any future maintenance is much easier.

⬢Place the hotend next to the Extruder-body, see the grooves in the printed part, which are in the shape of the hotend.

⬢Correctly placed hotend. Cables should point in the direction behind the hand, we will align them in the next step.

⬢Place the Extruder-body with the hotend on the box and make sure the cables are pointing down.

⬢Place your finger temporarily on the longer magnet and place the extruder motor assembly on the Extruder-body. The Bondtech gear might pull the magnet out while assembling parts together.

⬢Make sure both parts are aligned.

⬢Place the Extruder-cover on the Extruder-body. Again, make sure parts are properly aligned.

⬢先ほど用意したM3x40のネジ2本を差し込んで締めます。このとき、ネジの長さが全体の厚みより少し長いので、注意してください。

⬢X-carriage (1x)

⬢M3n nut (2x)

⬢M3nS nut (4x)

⬢IR-sensor cable (1x)

⬢Take both M3n nuts and using pliers (or screw) push them in the X-carriage, then using a screw from the other side, pull them all the way in.

⬢Don't forget to remove the screw.

⬢Take all four M3nS nuts and insert them in. Ensure correct alignment using the Allen key.

From now on, keep in mind the nuts are inside, avoid rotating the X-carriage "downwards", or the nuts might fall out.

⬢Take the IR-sensor cable and locate the end with the smaller connector.

⬢Place cable in the X-carriage, use the small printed overhangs to keep the cable inside.

⬢The distance between the connector and the X-carriage should be around 15 mm (0.6 inch). We will adjust it later.

⬢Guide the cable through the slot, remember this path, we will use it for other cables as well.

The IR-sensor cable colour might differ from yours, but the assembly procedure is the same ;)

⬢Make sure the motor cable follows the channel both in Extruder-body and X-carriage. In the X-carriage the motor cable will follow the path of the IR-sensor cable.

⬢Make sure the motor cable follows the channel both in Extruder-body and X-carriage. In the X-carriage the motor cable will follow the path of the IR-sensor cable.

⬢ENSURE NO WIRE IS PINCHED! Then use the M3x10 screw and Allen key with ball end to connect both parts together. If you are inserting the screw at this moment, it will be slightly inclined in the beginning, but it will "straighten up" after few turns. Don't tighten the screw completely, we need to adjust the IR-sensor cable.

⬢Turn the extruder to the other side and if needed insert the second M3x10 screw. Don't tighten the screw, we need to adjust the IR-sensor cable.

⬢Prusa IR-sensor (1x)

⬢M2x8 screw (1x)

⬢M3x40 screw (1x)

⬢Place the IR-sensor on the top of the Extruder-body and secure it with the M2x8.

Tighten the M2x8 screw, the sensor shouldn't be able to move, but be careful the PCB isn't indestructible ;)

⬢Connect the cable, mind the correct orientation of the connector and wires.

⬢Leave a slack behind the sensor like in the picture. Don't create too big loop as it might interfere with the frame. If needed adjust the length by gently pulling/pushing the cable.

⬢Ready? Ok, check once more no cable is pinched and tighten both M3x10 screws installed previously.

⬢For easier fan installation, remove temporarily the black wire from the cable bundle and release at least one loop. Then tie the bundle back, see the picture.

⬢Before you move to the next step, take an Allen key and GENTLY PUSH the motor cable to the channel to create space for the fan cable.

⬢First, create a loop on the cable. Make sure the black protective wrap is close to the edge of the fan. See the picture.

⬢Place the fan on the extruder and proceed in the following way:

⬢Extruder-idler (1x)

⬢Bondtech WITHOUT the hole for the lock screw (1x)

⬢Bearing (2x)

⬢Shaft (1x)

⬢M3n nut (1x)

⬢M3x40 screw (2x)

⬢Idler spring (1x) place the spring on the screw

⬢Take M3n nut and place it in the Extruder-idler.

Use the screw pulling technique.

⬢Insert the pulley in idler as shown in the picture.

⬢Slide the shaft through the idler and pulley. Use reasonable force or you will BREAK the printed part.

⬢Place your finger on the bearing and ensure it can rotate freely.

⬢Place the Extruder-idler in place and secure it using a M3x40 screw.

⬢Don't tighten the screw too firmly, it serves as a shaft for the idler. Check that the idler can rotate freely.

⬢Use the M3x40 screw with the spring to introduce tension to the Extruder-idler.

Hold the Extruder-idler on the other side, until the screw reaches the nut.

⬢Since there is only one screw, you need to introduce a large force. The head of the screw, should be aligned or slightly below the surface.

⬢Take the M3n nut and insert it all the way to the support. It is crucial!

Use the screw pulling technique.

⬢Place the support on the extruder and ensure the inclined part is facing "down" (towards the nozzle).

⬢Secure the support using an M3x10 screw.

⬢Insert M3nS nut in the Fan-shroud, all the way in.

Ensure correct alignment using the Allen key.

⬢Mount the Fan-shroud to the extruder, secure it using an M3x20 screw. Don't over tighten the screw, you can break the plastic casing. Also make sure the fan can rotate freely.

⬢First, slide the fan in the Fan-shroud and make sure it is aligned properly.

⬢Second, fix the fan in place using one M3x20 screw. Tighten carefully, or you will damage the fan's casing.

⬢Turn the extruder around and insert the M3n nut. No need to pull it in, we will use the screw.

⬢Place the remaining M3x20 screw from the other side and tighten it, but carefully, or you will damage the fan's casing.

⬢Guide the cable according to the picture in the channel. Bend it slightly towards the extruder. DON'T stretch the cable!

⬢Insert the zip ties in the X-carriage like in the picture.

⬢Lower the X-axis at about 1/3 from the top.

⬢Align the bearings like in the picture. Lower bearing position is approximate for now.

⬢Place the extruder on the bearings, the top couple must fit perfectly.

⬢We will adjust the lower bearing later on.

⬢Tighten and cut the zip ties.

⬢Place the cables on the P.I.N.D.A. sensor side over the lower smooth rod and push them back in the channel.

⬢Place the cables on the hotend fan side over the lower smooth rod and push them back in the channel.

⬢Align the bearing, so it fits nicely in the X-carriage

⬢Guide the X-axis belt through the X-end-idler, around the 623h bearing with the housing and back.

⬢Continue with the belt through the X-carriage.

⬢Guide the X-axis belt through the X-end-motor, around the GT2-16 pulley and back.

⬢X軸 ベルトの取り付けを続ける前に、X エンド の M3 ネジ を緩めてください。

⬢写真のように、X軸 モーターをフレームの方に少し回転させます。

⬢X-GT2 ベルト の フラットな部分を、2枚目の写真のように X キャリッジ に押し込みます。

ドライバーや一番小さい六角レンチを使って、ベルトを押し入れてください。

⬢右手でモーターをつかみ、元の位置へと回転させ、押さえておきます。(ベルトに張力がかかるようにします。)

⬢左手の2本の指で、ベルトを挟むようにつかみます。このとき、ベルトを曲げるために必要な力はとても小さな状態となっているようにしてください。ただし、つかむ前から自重でベルトが曲がってしまわないようにしてください。通常時には真っすぐになっている必要があります。

モーターを元の位置へ回転するのが困難な場合、ベルトの張力が強すぎます。

⬢ベルトの張力に合わせて、X キャリッジ に押し込むベルトの量を調節してください。

⬢調整ができたら、モーターを元の位置へ回転させ、M3 ネジ を再度固定します。

以下のステップに向けて、ホワイトマーカーをご用意されることをお勧めします。もちろん、ホワイトマーカーがなくても、ベルトの余分な部分を切断することはできます。

⬢切断する必要のある部分の長さを測り、X キャリッジからゆっくりとベルトを取り外します。ただしこのとき、張力を失ってしまわないよう、最低 3-4つ の歯は X キャリッジ に噛み合ったままになるように注意してください。可能であれば、ベルトの切断する部分に、マーカーで印をつけます。

⬢マーカーの位置が正しいかどうか、ベルトが張られた状態であるかどうかを、再度確認してください。

⬢ラジオペンチを使って、印をつけた場所でベルトを切断し、ベルトを X キャリッジ に戻します。必要であれば、ドライバーや六角レンチを使ってください。

⬢Black nylon filament 50 cm / 19.7 inch (1x)

⬢Using the pliers cut one end of the filament to create a tip.

⬢Check the tip is similar to the third picture.

⬢ナイロンフィラメントを差し込む穴を探します。一番小さい六角レンチを使って、穴の中に異物が入っていないことを確認してください。

⬢ラジオペンチを使って、ナイロンフィラメントをスロットに差し込みます。この際には、もう片方の手でエクストルーダーを押さえてください。

⬢フィラメントが正しくささっているかを確認するため、手でやさしく引いてみてください。X軸 が少しだけ曲がって、フィラメントがスロットから抜けなければ正しい状態です。

⬢もし上手くいかない場合には、フィラメントの先端を形状を調整してみてください。

⬢X-carriage-back (1個)

⬢Cable-holder (1個)

⬢M3x40 ネジ (1本)

⬢M3n ナット (2個)

⬢Take the M3n nut and place it in the printed part (all the way in).

Use the screw pulling technique.

⬢Tighten the X-carriage-back and the cable-holder together.

⬢Secure the screw by tightening the nut all the way to the surface. Do not use excessive force, as you might crack the printed part.

⬢Push the cables from the Extruder THROUGH the X-carriage-back start the print fan and P.I.N.D.A. sensor cables.

⬢In the next step add IR-sensor cable, then the extruder motor and hotend fan.

⬢Carefully insert the nylon filament and then slide the X-carriage-back towards the X-axis.

⬢M3x10 screw (4x)

⬢Use all four screws and tighten the X-carriage-back.

Tighten the screws with a reasonable force, make sure you won't deform/squeeze the bearings between the printed parts.

If you have issues with placing the X-carriage-back, make sure the bearings, especially the lower one, are seated properly.

⬢結束バンド (5本)

⬢ケーブルスリーブ 13 x 490 mm (1本)

パッケージには 3本 のケーブルスリーブが入っています。最も大きなものを使用してください。(直径と長さの一番大きなもの)

⬢Open one end of the textile sleeve and slide it on the cable bundle leading from the extruder. Don't forget to include the nylon!

⬢Leave the cables from the Hotend out for now.

⬢Length of the first wrap should be slightly longer than the cable-holder part.

⬢Gently twist the sleeve to make it smaller and tighter around the cables, orient the sleeve's seam downwards, then slide the sleeve towards the extruder.

⬢Ensure the cable-holder is properly oriented and at the end of the screw.

⬢Take 3 zip ties and tighten the textile sleeve to the holder.

⬢ここで、ホットエンドからの配線を cable-holder へとまとめます。

⬢ホットエンドからの配線がまとまったら、2本 の結束バンドを使って固定し、余分な部分を切断します。

⬢ケーブルスリーブをほどき、ホットエンドからの配線を差し込みます。

⬢すべてのケーブルをスリーブで巻いていきます。
