1、APPLICABLE MODELS: 3D printer CNC parts kit is suitable for VORON 0.2 R1 or for VORON 0.1, for VORON 0.2 (upgraded to 0.2 R1). 2、SURFACES ANODIZING: CNC aluminum alloy processing, surfaces anodizing, high processing accurate, high temperature resistance, not easy to deform, solidly structure, no cracks, can ensure the printer long term stable operation. 3、INCREASE PRINTING SPEED: Good compatibility, XY limit switch can be installed. The XY part of the connecting parts and the X slider are cut and weighed to make them lighter, reduce inertia and increase printing speed. 4、IMPROVED MOTION ACCURACY: The tensioner wheel uses customized stainless steel cylindrical screws to ensure that the tensioner wheel rotates with very little clearance, improving motion accuracy. 5、EASY INSTALLATION: The Aluminum alloy CNC parts kit is easy to install, only a few modifications to the original mounting base are required to complete the kit.
