Hello,

this is my version of a turntable. This turntable is controlled by a Arduino Nano and a Nema 17 stepper. My purpose is to use it for 3D scanning with FlexScan3D or with my Shining 3D Einstar. 

The Tabel has a outer diameter of 320mm.

BOM:

• Arduino Nano
• Nema 17 Stepper
• TB6600 Stepper Driver
• 12V Power supply
• Potentiometer
• 0,96 Zoll OLED I2C Display
• lazy susan 12 inch (30,5cm)
• 12mm Push button
• 4mm wood screws

Assembly:

My lazy susan has 7 mounting holes. I print 7 Bearing Mounts. This Bearing Mounts ar designed to be used with a 12mm thick Table. Lay the lazy susan flat on the Table and mark the outer Diameter. 
Saw a hole based on the marking. Insert the printed Bearing Mounts in the lazy susan and screw it in to the table. You can now insert the printed table in to the lazy susan. Mount the Nema17 stepper on the Nema17_Mount. Pres now the Sun_Gear on to the Nema 17 shaft. Scrow the Nema17_Mount in to the table. The last thing to do the cabling.

Cablin:

I have a Wokwi project that contain the cabling and a version of the Arduino code. The pins on the A4988 has the same naming as the TB6600 stepper driver. I use this Wokwi Project as a way of testing new versions of the Arduino code, so the code is not always functional. The latest stable code is in a .ino file on this page under files.

Future updates:

• New Arduino code that can switch between a Manual mode and FlexScan3D
• I'm planning a new version of the 3D printed table that includes magnets (drop in replacement).
• A menu function on the display
