Precise, flexible stepper control for robots, machines and 3D printers Key benefits Simple, tactile control: On-board buttons let you set rotation direction and speed without additional software, so you can adapt quickly to new scenes and prototypes. Accurate, repeatable motion: The LCD displays speed, delay and cycle times for precise adjustments and consistent results across runs. Built for versatility: Built-in working modes let the stepper motor driver automatically change direction and behavior, enabling multiple applications from one controller. What it does Controls stepper motor direction and speed via buttons for easy, on-the-fly adjustments. Shows speed, delay and cycle times on an LCD for precise motor control and quick verification. Switches direction automatically according to the selected working modes to support complex motion patterns and repeated cycles. Why you need it Cuts setup time: Manual button control and an informative LCD reduce the time spent tuning parameters. Improves reliability: Visible speed/delay/cycle readouts make it easy to reproduce motion profiles and avoid trial-and-error. Expands application options: Automatic direction changes and selectable modes let one controller serve multiple roles in different projects. Compatibility and performance Function: Stepper motor driver control with manual button input and LCD feedback. Compatibility: Designed to integrate with stepper-driven systems commonly used in robotics, machinery and 3D printing setups. Performance: Enables precise control over rotation speed, timing delays and cyclical operation through selectable modes and on-screen values. Practical use scenarios Robot joint testing: Quickly set speeds and cycle counts using buttons and confirm parameters on the LCD to run consistent, repeatable joint motion tests. 3D printer or filament system: Control feed or auxiliary axes with precise speed and cycle settings; automatic direction modes simplify bidirectional operations. Machine indexing or inspection rigs: Use delay and cycle settings to create timed, repeatable indexing motions with automatic direction changes between cycles. Who this is for Makers and hobbyists who need an easy-to-use, visible control interface for stepper motors. Engineers and technicians looking for a compact controller to prototype or deploy repeatable motion sequences without complex setup. Small-scale production or lab environments where quick reconfiguration and reliable cycles are required. What to expect Direct button-based control of rotation direction and speed. LCD readout of speed, delay and cycle times for precise, auditable settings. Automatic direction changes driven by selectable working modes to support multiple scenes and applications.
