This is the product that I am using

I wired the pins of parallel Port of my driver to the Arduino like that:
Arduino UNO. Parallel Port of Driver
GN| 18-25
8 | 1 (All axes Enable)
2 | 2
5 | 3
In the same way, I did wiring for other axes as well. The simple Arduino code that I run works fine for all the axes and I got the motion. But the LEDs on my board are dim and the controller display shows that the correct signals are received from UGS controller to the board and not enough I guess.
Below are certain pics of how I wired them
Edit: I have figured out that my driver works on enable HIGH and GRBL by default is for enable LOW drivers. So, I change the enable LOW to HIGH for the GRBL and now I am having motion. The problem now is my NEMA 23 vibrates back and forth when I give it a command. I am sorry if I sound stupid but I am from Mechanical background and know very less about the mechatronics side.
