The Spyder 3D World lab is equipped with several printers and a David scanner. In order to create uniform consistent rotations for better scans, Enrique and Kevin wanted to use the Virtumake Arduino turntable. Unfortunately, the servo and specified board were out of stock and not available for months. So, they fired up Solidworks and began designing what he needed, starting with a new base and table to retrofit a servo from Fry’s Electronics.
Here are the steps they took to customize the turntable and create precise, clean scans:
Use the Arduino compatible board . The “UNO R3 Development Board ATMEGA328P ATMEGA16U2 For Arduino Compatible” UNO R3 worked well.
The new servo also required a redesign of the base and table. Enrique and Kevin created these designs in SolidWorks, by measuring the board with calipers and then making the case large enough to fit the board, allowing for potential printer errors. It’s also designed to be an easy print. The infill density can be adjusted in the file from 10% to 100%, if desired.
Adjust the pins for the new design – digital pin 4(signal pin for the servo), 5v+ pin(power), and gnd(ground) pin.
Assemble accordingly and begin scanning.
