Compact 2phase, 4wire stepperdriven linear slider designed for precision shorttravel motion in DIY camera and small automation projects. The assembly combines an 8mm screw shaft and moving block to deliver controlled linear movement with a maximum 10mm stroke. Key benefits Precise shortrange positioning: the stepperdriven screw shaft converts rotary steps into accurate linear motion for repeatable small adjustments. Easy integration for DIY camera builds: compact size and straightforward mechanical design make it suitable for focus rails, microsliders, timelapse adjustments, and other camera accessories. Reliable, repeatable motion control: a 2phase, 4wire stepping setup allows stepwise control and integration with common stepper controllers and driver boards. Key attributes Drive type: 2phase, 4wire stepping electronic starter configuration (stepperdriven). Lead screw diameter: 8mm screw shaft. Travel (stroke): 10mm linear movement of the moving block. Functionality: linear slider / moving block that translates stepper rotation to linear displacement. Application focus: intended for DIY camera and small precision motion projects. What this solves Eliminates manual microadjustment struggles by providing motorized, repeatable shorttravel movement. Simplifies prototyping for compact motion systems where large linear actuators are impractical. Offers a ready mechanical solution when you need to convert stepper rotation into precise linear changes over a 10mm range. Typical use cases DIY camera focus or macro rail: add motorized fine focus or microadjustment to camera rigs for timelapse focus stacking or repeatable framing. Small automation or robotics: precise shortrange linear actuation in hobby robots, sensor positioning, or control panels where only a small stroke is required. Electronics bench or prototype fixtures: integrate into test setups that require controlled micromovement of components or probes. Installation and control notes Designed around a 2phase, 4wire stepper configuration; control using stepper drivers or controller boards compatible with 2phase, 4wire motors. Compact form factor is intended for integration into DIY assemblies and small enclosures where a 10mm stroke meets application needs. This linear slider assembly is intended for users who need compact, stepperdriven shorttravel motion in camerarelated or smallscale automation projects. Its 8mm screw shaft and 10mm movingblock stroke make it a practical component for precise, repeatable positioning tasks.
