MKS LV8729 stepper motor driver controller

MKS LV8729

Overview
MKS LV8729 is a  ultra quiet stepper motor driver, and good for Nema stepper motor whose current is less than 1.5A, which makes motor steady, quiet and precise.
Also, it does good work with MKS ROBIN, MKS GEN,MKS SBASE and RAMPS1.4 controller board on 3d printer, carving machine, CNC, etc.

Cautions
Please mind the connecting direction,

or else will burn the driver chip and controller board.

Microstep Setting
1.The jumpers on the board are M1,M2,M3. “High” means put jumpers on, while “Low” is off.

As follows:

2.The Algorithm and Adjustment  on LV8729 driver.
Formula: i=Vref/0.5, Vref defaults 0.4V.While current is 0.8A,1.5A Max.

As follows:

3.Please increase the current by rotating the potentiometer clockwise slowly.

While reduce by rotating the potentiometer  anticlockwise.

4.Please measure the Verf  by multimeter.
Cautions: please disconnect all motors, or will burn the drivers and board.
Please plug the power supply as well as USB.
