Compact, precise linear motion for small camera and DIY projects. This 8mm Stepper Electronic Starter is a 2phase, 4wire stepping module with an integrated linear slider and screwshaft moving block. With a 10mm stroke, it provides controlled shortrange travel suitable for microadjustments, focus rails, and other compact motion tasks. Key benefits Precise shorttravel positioning: the screwshaft moving block and stepper drive deliver repeatable, controlled linear movement over a 10mm stroke. Compact form factor: the 8mm size keeps the assembly small and easy to fit into tight housings and camera rigs. Simple stepping design: 2phase, 4wire configuration is a common stepping arrangement for straightforward integration into DIY builds. Ideal for camera and micro motion projects: engineered for smallscale linear tasks where fine movement and consistency matter. Core attributes Type: 2phase, 4wire stepping electronic starter Form factor: 8mm Motion element: screw shaft with moving block (linear slider) Stroke length: 10mm Intended use: DIY camera and small linear motion applications What this product solves Eliminates manual finetuning: replaces hand adjustments with repeatable motorized movement for focus, framing, or micro positioning. Saves space in compact designs: the small 8mm profile allows use inside limited enclosures or lightweight rigs. Provides predictable linear travel: the screwslider arrangement converts rotary stepping into precise linear displacement across the full 10mm stroke. Practical use cases Macro focus rail for cameras: add motorized, repeatable focus shifts for stacked macro photography or repeatable timelapse focus pulls. Small automated stages and positioning: integrate into prototype optical systems, sensor alignment rigs, or small desktop automation where short, accurate travel is needed. DIY camera sliders and lens shifters: implement controlled micromovements for creative effects and repeatable framing in compact camera builds. Integration notes (projectfriendly) Suited for smallscale DIY and prototyping projects requiring compact linear motion and short travel. The 2phase, 4wire stepping format supports common stepper control approaches used in hobby and DIY electronics. What's included (as described) 8mm stepper electronic starter module with screwshaft linear slider and moving block, providing a 10mm stroke for linear adjustment. This component is a practical, compact solution when you need controlled, shortrange linear motion for camera and small automation projects without taking up much space.
