Rotary Table Stepper Motor Adapter

thingiverse

I bought a 100mm rotary table for my milling machine from here. I needed to connect a stepper motor from SparkFun so I could control its rotation with an Arduino to make gears. This setup is great because one step of the stepper motor advances the rotary plate by 1/80th of a degree and does it fairly automatically. The first task in this project was designing a connection support that attaches the stepper motor to the axle of the 100mm rotary table. An OpenSCAD file is attached that allows you to print the main body of the support or mill and lathe the main body from two chunks of aluminum and assemble them together. The uploaded STL files provide the components if they are going to be 3D printed. This project is in progress; my next step is to 3D print a support structure that holds a display, keypad, Arduino, and stepper motor board together to control the stepper. Assembly Components Required To attach this to the 100mm rotary table, you need two M5 12mm button-head screws. To attach it to the motor, you will need four M3 10mm screws.
