Design Example: Stepper-Driven Turntable

oblique

This example demonstrates combining an off-the-shelf lazy-susan bearing with a stepper motor. The bearing provides robust support for a load attached to the output gear. The gears provide a reduction stage to increase the precision and torque output of the stepper motor. The result is a low-precision but low-cost laser-cuttable rotation stage.

The SolidWorks model files and individual DXF cutting files may be found in the FlatPackExample/Stepper-Turntable folder, or may be downloaded as a single file as Stepper-Turntable.zip.
