● Silent step protection is an additional module step and Pololu A4988 compatible step motor driver. The board provides the motor output with a flyback diode (free rotating diode), which enables it to withstand induction voltage even when the driver is not powered.
● The v2 protector also includes a diode from the logic voltage (anode) to the motor voltage (cathode) to ensure the power sequencing of all silent steppers..
● This type of eliminator is mainly used for vibration of a 3D printer having a parallel arm structure. Especially motors with lower resistance are more effective. It can effectively eliminate uneven signal waves at low speeds and obtain relatively flat signals.
The effect varies depending on the machine and the condition of the motor.
