A precise, easy-to-read belt tension gauge built for 3D printers and other machines using 2GT timing and synchronous belts. Use it to set consistent belt tension, reduce print artifacts, and verify tension after maintenance. Key benefits Accurate tension measurement: Digital screen gives clear, repeatable readings so you can set and compare belt tension reliably. Faster setup and maintenance: Quick measurements reduce the guesswork and time needed for initial setup or routine checks. Durable contact and consistent readings: Metal probe ensures reliable contact with the belt for stable measurements over repeated use. Safe for common belts: Designed for 2GT timing belts and synchronous belts used on most desktop 3D printers and similar equipment. Simple and robust construction: ABS body with a silver finish provides a practical, lightweight tool that resists everyday workshop handling. Features and attributes Function: Measures belt tension for adjustment and verification. Readout: Digital screen for easy, precise viewing of measured values. Probe: Metal probe for durable and consistent contact with the belt. Material and finish: ABS construction with a silver finish for a professional, practical appearance. Compatibility: Specifically suitable for 2GT timing belts and synchronous belts. How it helps Diagnose and fix print quality issues by identifying under- or over-tensioned belts. Standardize tension across multiple axes to improve repeatability and reduce mechanical slop. Verify correct belt tension after replacement or maintenance to prevent premature wear and missed steps. Typical applications 3D printer setup and calibration: Measure and match belt tension on X and Y axes during initial assembly or after upgrades. Routine maintenance: Quickly check belts during periodic service to maintain consistent print quality. Hobby robotics and small CNC machines: Confirm and adjust tension on systems that use 2GT timing or synchronous belts. Practical notes Use the digital readout to record baseline tension values for each axis and recheck after any adjustments. The metal probe is designed for consistent contact; ensure proper placement on the belt tooth surface for repeatable readings. Compatible with 2GT timing belts and common synchronous belts—use accordingly when selecting the tool for your equipment. A straightforward tool for anyone who needs reliable, repeatable belt tension measurements on 3D printers and other machines using 2GT timing or synchronous belts.
