Measurement:

The drive current must be converted by measuring the driving voltage. The method of measured the driving voltage VREF can refer to the voltage between the knob on the driver to the USB interface, which is deemed to be VREF.Drive current can be converted through VREF through different drivers.adjust:

The VREF can be adjusted according to the operation of the motor. By adjusting the knob above (clockwise, increasing clockwise, reducing counterclockwise):

Before adjusting the knob, it must be performed in the case of power off. The adjustment is adjusted and then the power measurement is performed to prevent drivers or motherboards from burning.

Drive current algorithm and adjustment:

1. VREF measures the voltage of GND and the middle end of the potentiometer.

2 Do you must connect the motor when measuring the voltage, otherwise it is easy to burn the driver.

3. When the measurement voltage is measured, the power should be connected. Do not just connect USB to power.

Please pay special attention to the direction, do not insert it!

How to use:

1 When using on the printing control board, please keep the three jump caps under the socket

2. Pay attention to the direction, refer to the figure above.

3. It can be used directly on MKS SGEN-L.

4. The direction of the motor is the opposite of 4998 and 8825. If you want to replace 4988 directly,

Please adjust the firmware or adjust the motor connection.
