Customizable turntable motorized with NEMA 17 stepper

prusaprinters

<p>Designed and printed this for recording video of models. Could also be used for 3D scanning or any other purpose.</p><p>The turntable with a 100mm diameter uses about 20 grams, or 6.5 meters of filament. With the material saving holes the amount of filament used is about 15 grams.</p><p>I used a SparkFun RedBoard (Arduino UNO compatible) and this Adafruit motor driver:</p><p><a href="https://www.adafruit.com/product/1438">https://www.adafruit.com/product/1438</a></p><p>to control the NEMA 17 stepper motor. If you want to do the same you can download the Adafruit example sketch associated with that motor driver as a starting point and modify as desired. I used the MICROSTEP in my main loop() because it is smooth, quiet and slow. My Arduino .ino sketch is included in the files.</p><p>The stepper motor sits in a small frame inside the base. I didn’t glue it in or secure it, but you certainly could.</p><p>I’m a novice with OpenSCAD so the included sketches are not perfect. I probably can’t answer your OpenSCAD question but there are many resources online.</p><p>If you use all or part of this I would enjoy seeing your build.&nbsp;</p><p>Please click the “like” button if you like this.
