Step 3 –wiring the LCD
Needed parts:
Control unit (after Step 2
Jumper Wire 10cm m-f
Back:
Description:
Wire the connections according to their labels. (GND-GND / VCC-VCC / SDA-SDA / SCL-SCL)
Important note:
This step should be double checked to ensure that the pins are properly connected, otherwise the
control unit and / or the display can be destroyed!

Step 4a –Stand 1
Needed parts:
Stand1_Nema_17.stl
Nema 17 (min. 40Ncm)
M3x8mm (4x)
Gear_Small.stl (optional v2)
(1) (2)
Description:
(1) Mount the stepper motor with four M3x8mm Screws onto the Stand1.stl.
(2) Press the Gear_small.stl onto the motor shaft. Make sure, that the gear and the motor shaft close
flush at the front.
Note:
Depending on the printing accuracy, it may be necessary to pre-drill the screw holes with a 3mm drill
bit. Furthermore the gear and the motor shaft might have a tight fit and you might have to „gently“
use the help of a hammer.
11
Step 4b –Stand 1
Needed parts:
Stand1_Nema_17.stl (after Step 4a)
Adapter2.stl
Steel pin (d=6mm, l>50mm)
(1) (2) (3)
Description:
(1) The steel pin is pressed into the opening of the side stand.
(2) The larger gear (Adapter2.stl) is pressed onto the steel pin.
(3) The steel pin (top) and the motor shaft must NOT protrude forward from the components and
should be flush with the surface. Superglue can be used to fix the position of the gears.
Note:
Both gears should match well and rotate relatively resistance free. If this is not the case, it may be
necessary to replace the small gear with v2.stl or adjust the printer settings.
12
Step 5 –Stand 2
Needed parts:
Stand2.stl
Adapter1.stl
Steel pin (d=6mm, l>50mm)
(1) (2)
Description:
(1) The steel pin is pressed into the opening of the side stand
(2) The adapter1.stl is pressed onto the steel pin. It is important to ensure that the steel pin does not
protrude forward from the adapter.
Note:
The adapter can be fixed with superglue on the steel pin. It must be ensured that the steel pin can
rotate freely in the stand.
13
Step 6 –Turntable
Needed parts:
Turntable_Base_small.stl
Nema 17 (min. 40Ncm)
M3x8mm (4x)
Rotary_Arm.stl (2x)
Turntable_Adapter.stl
Description:
(1) Connect the Nema 17 with 4 M3x8mm screws with Turntable_Base_small.stl:
(2) Place the Rotary Arm (2x) on the sides of the turntable_base.stl (red mark) and press any
Turntable_Adapter.stl onto the motor shaft:
Note:
The connections marked red in the second picture can be fixed with super glue if they are too loose.
14
Step 7 –Tilting mechanism
Needed parts:
Stand 1 (after step 4b)
Stand 2 (after step 5)
Turntable_Base_small.stl (after step 6)
M3x12mm (2x)
Description:
The two M3x12mm screws are screwed laterally into the adapters (red mark), so as to connect the
side stands with the rotating arm (Turntable_Base + Rotary_Arm). The height has to be adapted to
the print object (see next page).
15
Step 8 –Setting the Scanning Volume
Description:
Depending on the object, the height of the tilting mechanism must be adjusted. This can be done by
loosening the screws used in step 7 and adjusting the height accordingly. The goal is that the center
of the object is in the center of the two roational axis, as shown in the following image:
(1) optimal height:
(2) object to low:
(3) object to high:
16
Step 9 –Wiring the stepper motors and control unit
Needed parts:
Control unit (after step 3)
Tilting mechanism (after step 7/8)
Stepper motor cable >70cm (2x)
Description:
The motors are connected to the control unit as shown.
Rotor = (1)
TT = (2)
TT = (2)
Rotor = (1)
12V DC

Step 10 –(optional) Mounting on a base plate / work surface
Needed parts:
Tilting mechanism and control unit (after step 9)
Screw for wood (d=3mm) or alternatively double-sided tape
Wood panel (min. 600x150mm)
Description:
The tilting mechanism and the control unit are mounted on a base plate. This can be done either
temporarily with double-sided tape or more durable with wood screws.

Accessories
Remote Control –Bluetooth for Android/iOS
A modified Bluetooth trigger can be used to trigger most smartphone
cameras. The shown module is operated with a CR2032 button cell, which
must be inserted on the back. As soon as the On / Off switch has been
flipped, the blue LED lights up at regular intervals. The device must then be
paired with the smartphone via Bluetooth. This can be done in the
smartphone’s setting menu. The device should be visible as “AB Shutter 3”
and has to be coupled accordingly
To connect the Bluetooth module to the control unit, the enclosed cables
are used. The female DuPont plugs are plugged into the Bluetooth module.
Attention: The upper connectors are for iOS, the lower for Android! (See
picture below). You can test the functionality of the trigger by shorting the
male ends of the cables.
The male DuPont plugs are then plugged into the outer-right two sockets
on the control unit (Opto). Be careful choosing the right pins, as the wrong
pins might destroy the bluetooth device!

Remote Shutter Control –Infrared
Important: Set Camera mode to the appropriate camera model (settings menu)
Many cameras can be triggered by infrared. This function is to be activated in the corresponding menu
of the camera (see user manual of your camera model). An infrared LED is connected to the control
board of the scanner (see below) so that it emits a predefined light pulse at the given times. This light
is not visible to the human eye (but not harmful either). You can sometimes see the light pulse as a
slight pink flicker on the display of the camera, as the sensor of the camera registers the infrared light.
However, some cameras (for example Iphones) use an infrared-filter, so the light pulses are not
displayed. It should also be noted that these are very short light pulses (<0.1s). Note: If the camera
does not detect a light pulse as soon as a scan routine is started, the connectors should be reversed.

Remote Shutter Control –Modifying a remote control
For (almost) all cameras you can buy a standard remote release, which can be connected to the camera
by cable. These can be modified easily and also connected to the Scanner’s control unit. A very
extensive source for various camera models and home-made remote releases is the following page:
http://www.doc-diy.net/photo/remote_pinout/. A modified trigger can be connected to the control
unit similar to the Bluetooth module (see: Remote control - Bluetooth for Android / iOS).
An existing remote release can be modified with minimal soldering skill and a total of two soldering
points. The following pictures describe the basic procedure:
(1)-Remote Control for Nikon/Canon (ca. 5€)
(2) Opening the enclosure
(3) Identification of the connectors
(4) The shown points (red circles) have been contacted with two male jumper wires, that can be
connected to the Scanner. By shortening the two wires the remote will send a pulse to the camera and
trigger the shutter.
These contacts are usually bridged by
pressing the button (see first image)
These contact points can be used to connect
two cables, that can later be connected to
the scanner’s control module.
