Here's what I sent them.

Several years ago I purchased a driver and breakout board from you. I has worked great for me. It's a 4 axis board and I never used the 4th axis. Now I'm trying to connect the 4th axis and having some trouble. The motor only turns in one direction. I'm not getting a voltage drop on the driver board on pin#9, when I reverse the motor. It drops on the breakout board but not on the driver board. Do you have any ideas what I could try? I don't see the driver board on you e bay page anymore, are you still selling them? I think I got mine in 2007.
Thank You,

This is the answer I got from them.

Hi Jerry, Sure It is possible your mach3 pinouts are incorrect, because pin 9 is the step pin and the voltage should not drop on that. Pin 8 is the actual direction pin. and pin 5 is the enable pin. See if that changes anything. Sorry, not carrying that anymore.

I may have all my pins wrong, I don't know, but it's been working. I have pins 2,3 on the X axis, 4,5 on the Y axis, 6,7 on the Z axis and 8,9 on the 4th axis. I'm not sure what the guy is telling me.

He is trying to say that pin 8= direction and pin 9 = step.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

I've done that it just runs in the opposite direction only. I wasn't sure what he meant by pin 5 being the enable pin. ??

If these are standard step and direction drives, changing the step pin for the direction pin should not allow it to move at all. It might move one step when it tries to change direction but that would be about it.

Here's a 4 axis file he sent me. I'm not going to be able to try it for a while. Not really sure what to do with it.

Well, it appears to be a problem with the board. I have another one coming and we'll see if it works. Thank you for your suggestions.
