This TL-smoother module mainly used for 3D printer motors, especially for parallel arm configurations of the machine effect is significant. Lower vibration lower noise smoother result. Features - Color: As Shown. - Material: Aluminum. - Size: 12.00X10.00X3.00 cm/ 4.72X3.93X1.18 inch. - This TL-smoother module mainly used for the vibration of the 3D printer in parallel structure. - And it can the uneven signal wave at low speeds effectively and achieve the signal wave of relative voucher. - Connect the TL smoother module to the corresponding position of the motherboard driver socket and the motor. - You can also cut the motor wire into two sections and solder the board between them to achieve better conductivity. - Pacakage Includes: 4 -Smoother plus module and 4 x heatsink. Package list: 4 -Smoother Plus Modules 4 x Heatsinks
