- Page 3 Base + Ring Base Ring Make sure that the ring can slide relatively freely before continuing with the next steps.
- Page 4 Mounting the Turntable Motor 1x Base+Ring 1x Nema17 small 4x M3x8 Make sure to mount the small stepper motor (Turntable) first. The motor connector should face to the left.
- Page 5 Mounting the rotor motor 1x small gear 1x Nema17 large 4x M3x8 Press the small gear onto the motor shaft of the larger stepper motor. Mount the stepper motor with four M3x8 screws like shown below. Move the large ring a couple of times to make sure, that the gears fit.
- Page 6 Mounting the Raspberry Pi 1x Raspberry Pi 4x M3x8 Make sure to not overtighten the screws as this might bend and damage the board.
- Page 7 Preparing the Ringlight Module 1x Ringlight 1x Pi Camera v2.1 2x M2x6 6x M2 nut (1) Insert the M2x6 screw (2x) (2) Add two nuts (2x) (3) Add the Camera Module (4) Tighten the camera module using two M2 nuts.
- Page 8 Preparing the camera cable 1x camera ribbon cable (50cm) Insert the camera ribbon cable through the two slots (red arrows). Make sure that the metal plating of the cable is facing the stepper motor (yellow circle). Take your time with that step, the cable should not bend sharply.
- Page 9 Close-up Continue through the next slot (again the metal plating should be facing away from you)
- Page 10 Insert the camera ribbon cable into the socket. The metal plating should be facing away from the USB/Ethernet ports (yellow circle).

- Page 12 Connecting the Ringlight Module 1x JST XH 3P (50cm) Connect the camera ribbon cable with the camera. The Metal plating is facing down. If you have two JST cables (20cm+30cm) use the longer one to connect to the ringlight.
- Page 13 If you have two JST cables (20cm+30cm), connect the smaller one like shown above (red arrow) Use the two slots (yellow circles) to guide the cable.
- Page 14 Connecting the Pi Shield 1x Frontplate with Pi Shield 2x stepper motor cable Turntable (small Nema 17) Rotor (large Nema 17) JST XH 3P (from ringlight module, see previous step) And connect the stepper motor cables to the corresponding stepper motors...
- Page 15 Mounting the Frontplate 1x M3x8 or M3x12 Bottom view: Mount the frontplate to the base and make sure that the pin headers of the Raspberry Pi and the Pi shield are properly aligned. (Yellow circle)
- Page 16 Use the M3 screw to connect the frontplate to the base.
- Page 17 Mounting the Backplate 4x M3x8...
- Page 18 You might use some zip-tie to cleanly store the cables behind the back plate.
- Page 19 Mounting the Diffuser/Polarizer 1x Diffuser/Polarizer This step is optional but can greatly enhance the image quality. The diffuser makes the light more even and the polarizer can absorb almost all reflections. The diffuser/polarizer module is a snap-on part and should be mounted like this: The polarizer consists of two pieces of linear polarizer foil, which are mounted perpendicular to each other.
