Step 2 Selector assembly: Parts preparation

Selector assembly: Parts preparation
Selector assembly: Parts preparation
For the following steps, please prepare:
Selector (1x)
10x6x2 Magnet (1x)
Magnetic steel ball (1x)
Make sure you are using the newly supplied ball, not the old one.

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.

There is an opening on the side of the selector through which you can observe the ball's position.

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

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 screw (2x)

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.
Fix the trapeze nut in place with two M3x10 screws. Tighten them just slightly for now. We will tighten them up fully later on.

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.

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

Selector assembly: SuperFINDA probe
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 with the top inner surface of the D-shaped opening on the side of the selector.
Ensure the sensor's bottom part is aligned perfectly in the D-shaped opening. Even though the SuperFINDA sensor's height might need further adjustment, this is usually a good starting point.
Fix the probe in place with M3x10 screw. Tighten the screw up just so that the sensor can no loner be moved.
Avoid over-tightening the screw; if SuperFINDA is securely held in place, that's sufficient.

Step 11 Selector assembly: Cutter parts preparation

Selector assembly: Cutter parts preparation
For the following steps, please prepare:
M3nS nut (1x)
M3x10 screw (1x)
Blade holder (1x)
Blade (2x) - stored in the little plastic box
Be very careful while handling the blades! You might easily harm yourself!

Insert the M3nS nut into the marked opening on top of the selector. Push it all the way in.
Insert the two blades into the recess on the back of the selector. Make sure the blades are seated nicely and do not overlap each other. The blades should be as close together as possible.
Cover the blades with the blade holder. Verify the blades are still seated perfectly in place while attaching the cover.
Fix the blade holder in place with M3x10 screw. Tighten it up fully.
