So he decided to replace the stepper motor controller in his turntable and document the process for anyone else who’s scanner might be struggling. Plenty of room for expansion.

Stepper motors are simple and cheap to use, and you don't need to have a fully closed-loop controller to use them accurately. Servomotors are much faster, but for guaranteeable positioning accuracy, ...

Each axis of the stepper controller has six output connections. Each group of three wires connects to a pair of coils. Linear slides are key to the design of a functional machine.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

The programmable unit controls Size 23 and Size 34 stepper-motor units. The easy-to-use electronic drive and fully programmable control unit has a patent-pending graphic-user interface.

If you’re a thoroughly modern hardware hacker who prefers using a web browser to twiddling knobs, then perhaps you’d be interested in the WiFi enabled stepper motor controller we covered recently.
