Are you using Mach2 or Mach3? In the other thread, I said to increase the direction pulse width. In Mach2 it's called direction prechange. both are in the motor tuning.

Frustrated beyond limits!! I have set my Gecko & stepper & Breakout board up and wired them carefully, but no matter what motor I use, I can NOT get the steppers to spin in both directions!
The motor jogs smoothly, and I'm convinced its a Mach2 software setting!
Step is using pin 2 and active HI
Direction is using pin 3 and active LOW
Please help me!

Hi Gerry,
Using Mach2 software.
I tried changing that setting, it just made my motor start really fast then slow to current jog percentage of 50% it had no effect on the rotation direction.

If they really don't go in the opposite direction then I would suspect that your direction signal is not properly connected...or you're using the wrong pin.
need to set your outputs both to active low.

ViperTX: both Mach2 & the Bidirectional Breakout board are using the same pins.

PoppaBear10: I have set both outputs to Active LOW

Ger21: Your right, I was confused with the Acceleration & Velocity.
When I set the Direction Precharge to 3, the motor ran smooth in one direction, and vibrated without spinning in the other.
I noticed that CNC2PC.com has two boards:
a: Bidirectional Breakout Board
b: Parallel Port Interface Card
I have the Bidirectional Breakout Board, did I get the right one?
Just make sure it's set for pins 2-9 to be output.
Try increasing the direction prechange to 5,10,15,20,25 and see if it makes a difference.

The bidirectional board should work. Does it have a jumper to make it look like a plain parallel port?

No
Question,
Are the Step & Direction line Output only?
