This can improve positional resolution, reduce vibration and ringing, and lower moving mass—particularly valuable on fast CoreXY machines where gantry dynamics directly affect print quality.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eWhy Choose Gates EPDM?\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003eEPDM is often considered the \"industrial premium\" choice, specifically designed for harsh or high-performance conditions.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eExtreme Heat Resistance:\u003c\/b\u003e EPDM is rated for \u003cb\u003e-45°C to +135°C\u003c\/b\u003e.

Open-Loop (Linear) Belts: The Spiral Cut\u003c\/h4\u003e\n\u003cp\u003eStandard open-loop belt stock is often manufactured as a very wide sleeve on a large drum.
