❃❃ The TL-Smoother is an addon module for 3D printer stepper motor drivers; the board provide flyback diodes(freewheeling) for the motor outputs, and protect the inductance voltages of the driver in the unpowered status. ❃❃ 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 conductivity. ❃❃ You will got smoother movement especially on the delta-style 3Dprinter under DVR8825 stepper drivers and A4988/2 drivers.
