Hey! I'm making a CNC with a 3 axis integrated TB6560 and an Arduino uno. As the 3 axis TB6560 has a Parallel Port connection so I connected the Arduino UNO pins to the parallel Ports to install GRBL in it. When I run a simple Arduino code all my three NEMA 23 motors move well (I have a noise from these motors and their shaft is tight when still, when it moves the noise ends). I then installed GRBL on my Arduino and used UGS to see the motion. Unfortunately, I have no motion with it. I could see that my controller display shows motion in the axis when I press the jog in UGS, the LEDs on my controller are very dim (which indicates the motion in the axis) and I think this might be the reason why it's not moving the motors.
Please bring up pen and paper and make a little schematics how You wired the drivers. Likely You're not using the correct pins, misses and Enable....
As You tell the steppers are stiff at stand still powering looks okey.
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.
