8mm Stepper Electronic Starter — 2Phase 4Wire Stepping Linear Slider with Screw Shaft Moving Block (10mm Stroke) — ideal for DIY camera rigs and micropositioning Why you need this part Compact precision: The 8mm form factor with a dedicated linear screw shaft moving block delivers controlled, repeatable linear motion in a very small package. Accurate short travel: A defined 10mm stroke provides exactly the microlength movement needed for focus adjustments, closeup sliding, and fine positioning without excess travel. Reliable stepper control: The 2phase 4wire stepping design gives stable, repeatable steps for smooth motion and predictable positioning in electronic control systems. Key benefits Solves smallmotion challenges: Makes microadjustments simple for camera builds, optical setups, and prototypes where manual control is impractical. Reduces setup friction: Integrates directly into DIY camera rigs and small automation tasks to manual sliders or improvised solutions. Repeatable and controllable: Stepbased motion enables precise, incremental moves—helpful for focus stacking, timelapse panning, and repeatable testing scenarios. Main features and attributes Size: 8mm compact stepping assembly for tight or confined installations. Drive type: 2phase, 4wire stepping electronic starter configuration for stepper motor control. Motion mechanism: Linear slider with screw shaft moving block for mechanical linear travel. Stroke: 10mm total linear travel for precise shortrange positioning. Application orientation: Designed for DIY camera projects and other micro linear motion needs. Functionality and compatibility Designed to be used where a small, electrically driven linear actuator is needed; compatible with control systems that support 2phase, 4wire stepper devices. Provides controlled linear motion through a screwdriven moving block, suitable for repeatable electronic stepping control. Typical use cases DIY camera focus slider: Add precise 10mm focus or microslide adjustments for macro photography, focus stacking, or closeup timelapse rigs. Small automation and instrumentation: Use as a micropositioning stage in prototypes, sensor alignment, or laboratory fixtures requiring short, repeatable travel. Compact robotics and mechanisms: Integrate into small robotic assemblies, optical mounts, or devices that require a compact linear actuator with stepper control. What to expect in use Smooth, incremental linear movement across the 10mm stroke when driven by standard 2phase stepper control signals. A compact footprint that fits into small assemblies where larger linear actuators would not be practical. Predictable positioning suitable for repeatable tasks in DIY camera builds and smallscale automation. Notes for planners and builders Confirm your controller or driver supports 2phase 4wire stepper configurations. The product is targeted at applications requiring shortrange, precise linear motion such as camera modifications and micropositioning tasks. Includes (as described) 8mm stepper electronic starter assembly in 2phase 4wire stepping configuration with linear slider screw shaft moving block and a 10mm stroke for DIY camera and micromotion applications.
