Description: The retarder is mainly aimed at the vibration of the parallel-arm 3D printer when printing Especially the use of 8825-driven and relatively low resistance motor effect is more obvious Can effectively eliminate the uneven signal wave at low speed, so as to achieve a relatively flat signal wave Effect In the use of 8825-driven Delta 24V power supply models the most obvious effect Specification: Material: composite plastic Size: 50x30x10mm Scope of application: 3D printer Package Includes: 1x stripper 1x cable
