2040 Yaxis belt tensioner for Ender 3 Material and durability: made from aluminum alloy, with wearresistant and deformationresistant properties to maintain stable belt tension over time. Surface finish: anodizing treatment provides wear resistance and corrosion resistance, helping the part stay reliable in varying prints and environments. Compatibility: specifically designed for Ender 3; not compatible with Ender 3 Pro. Key benefits: improves Yaxis belt tension stability, reducing belt slack and play, which helps achieve more consistent layer alignment and print accuracy. What makes it stand out: combination of rugged aluminum construction and durable anodized finish offers a reliable tensioning solution tailored to the Ender 3 platform. Use scenarios: 1) Upgrading an Ender 3 to improve Yaxis belt tension and stability for higherquality, more repeatable prints. 2) Replacing a worn stock Yaxis tensioner on an Ender 3 to reduce belt slip and chatter during longer print jobs. 2020 Xaxis belt tensioner for CR10 series and Ender3/Ender5 family Material and durability: constructed from aluminum alloy with wearresistant and deformationresistant properties to maintain consistent Xaxis belt tension. Surface finish: anodizing treatment for enhanced wear and corrosion resistance, contributing to longterm reliability. Compatibility: compatible with CR10, CR10S, CR10S4, CR10S5, CR10V2, CR10SPro, CR10SV2, CRXPro, CR6SE, Ender3, Ender3 Pro, Ender3 V2, Ender5, Ender5 Pro, Ender5 Plus, SV01, SV02. Key benefits: provides stable, precise Xaxis belt tension across a wide range of printers, helping to minimize belt slack, reduce print defects, and improve dimensional accuracy. What makes it stand out: broad compatibility across CR10 and Enderseries models, coupled with a durable aluminum alloy and anodized finish that resist wear and corrosion over time. Use scenarios: 1) Upgrading CR10 family printers to reduce Xaxis belt slack at higher print speeds or when printing with tighter tolerances. 2) Standardizing belt tensioning across multiple machines (Ender3, Ender5, SV01/SV02) in a multiprinter setup to maintain consistent print quality. Notes The 2040 Yaxis tensioner is intended for Ender 3 only and is not compatible with Ender 3 Pro. The 2020 Xaxis tensioner covers a broad range of CR10 and Enderseries models, providing a versatile solution for improving belt tension and print reliability across these platforms.
