Step 1 Tools necessary for this chapter

⬢Please prepare tools for this chapter:

⬢1.5mm六角レンチでナットの位置合わせが可能

⬢M3 ネジ向けの 2.5mm 六角レンチ

Step 2 Selector assembly: Parts preparation

⬢For the following steps, please prepare:

⬢Selector (1x)

⬢10x6x2 Magnet (1x)

⬢スチールボール (1個)

MMU2Sからアップグレードする場合は、古いボールではなく、アップグレードキットに含まれる新しいボールを使用してください。

新しいボールは強磁性体でできています。

Step 3 Selector assembly: Magnetic ball

⬢Insert the magnet into the marked opening on the selector. Push it in until it is flush with the surrounding surface.

The orientation of the magnet doesn't matter.

⬢Insert the magnetic ball into the marked hole on the top of the selector.

⬢The steel ball should be attracted to the magnet below and stay in place. If not, verify you are using a correct ball.

セレクターの側面には開口部があり、そこからボールの位置や動きを観察できます。

The selector ball from the older MMU2S can't be re-used as it is non-magnetic. Use only the supplied MMU3 magnetic version.

Step 4 Selector assembly: Trapeze nut parts preparation

⬢For the following steps, please prepare:

⬢Trapeze nut (1x)

In case you're assembling the unit from scratch, the nut is inside the Motor kit box, attached to the selector motor.

⬢M3n nut (1x)

⬢M3nS nut (1x)

⬢M3x10 ネジ (2本)

Step 5 Selector assembly: Trapeze nut installation

⬢Insert the M3n nut into the marked opening in the selector, just below the magnet. Push it all the way in. Make sure the magnet doesn't get pushed out.

The easiest way of inserting the M3n nut is by an M3x30 screw used as a handle.

⬢Insert the M3nS nut into the marked opening on the other side of the selector.

⬢Attach the trapeze nut onto the selector. There is a recess into which it should fit nicely.

⬢M3x10のネジ2本で台形ナットを固定します。今は少しだけ締めておき、後で完全に締めるようにします。

Step 6 Selector assembly: Rods and Cover parts preparation

⬢For the following steps, please prepare:

⬢M3nS nuts (2x)

⬢ブッシング・チューブ 5x6x25bt (2個)

⬢M3x10 screws (2x)

⬢セレクターフロントプレート (1枚)

Step 7 Selector assembly: Bronze bushing tubes

⬢Insert the bronze bushing tubes into the marked openings on the selector as far as you can, using your hand. Make sure you are inserting them from the correct side.

⬢Press the tubes in by carefully pushing the assembly against a flat surface.

⬢In the end, the tubes should end up flush with the surface on the other side.

Step 8 Selector assembly: Rods and Cover

⬢Insert the two M3nS nuts into the marked openings on the side of the selector. Push the nuts all the way in using the 1.5mm Allen key.

⬢Add the front plate onto the selector. Make sure the side of it is flush with the flat part of the selector.

⬢Attach the front plate with two M3x10 screws. Tighten them up.

Step 9 Selector assembly: Finda parts preparation

⬢For the following steps, please prepare:

⬢SuperFINDA sensor (1x)

Your sensor might look slightly different if you are re-using the older FINDA sensor. But don't worry, it will work just as good.

⬢M3x10 screw (1x)

⬢M3nS nut (1x)

Step 10 Selector assembly: SuperFINDA probe

⬢Insert the M3nS nut into the marked opening on the front of the selector.

⬢Insert the SuperFINDA sensor into the corresponding opening in the selector.

⬢Adjust the position of the sensor so that it ends flush or slightly above the inner surface of the D-shaped opening on the side of the selector.

Ensure the sensor's bottom part is aligned and doesn’t protrude into the D-shaped opening! Even though the SuperFINDA sensor's height might need further adjustment, this is usually a good starting point.

⬢プローブを M3x10 ネジで固定します。センサーが動かなくなる程度にネジを締めます。

SuperFINDAセンサーがしっかりと固定されていれば十分です。
