TL-Smoother: the TL-smoother filter moduleis an addon module compatible with 3D printer stepper motor drivers, the board provide flyback diodes(freewheeling) compatible with the motor outputs, and protect the inductance voltages of the driver in the unpowered statusFunction: this TL-smoother module mainly used compatible with the vibration of the 3D printer in parallel structure, and it can eliminate the uneven signal wave at low speed effectively and achieve the signal wave of relative voucherConnection:connect the TL-smoother module to the corresponding position of the motherboard's drive socket and motor, or you can cut the motor wire into two pieces and soldering the board between them and then will achieve better conductivityColour: BlackMaterial: PCBPackage Contents:5 x 3D stepper motor filter5 x jumper wiresOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
