MACH3 help. motor turns 1way only? Answered

Hey, I'm Building a 3axis CNC milling machine.
I've made a test setup with one motor, driver, controller, computer.
Got the motor turning, but only one way, no matter if I press arrow (on keyboard) up or down.

I've connected:
Step P2
and have setup the ports/ pin config menu to that.

I've connected an external 5V power supply to the driver board.
The motor is connected as instructed by the seller.

please help me...

There are two possibilities: Software or hardware. I'd check to see if the computer DOES change the "DIR" pin level, when you think you are reversing the motor ? If it does, and the motor doesn't change direction, check the wiring of the controller and the motor.

tried changing the outputs to P7 and P8... it worked, must be an error on the breakout board ;)
