Righty... So I've finally got round to getting a PCIe-parallel card, and have been playing around for most of yesterday trying to get this to work.

I started by checking that my power supply was outputting actually 24v, not 30v which if the potentiometer has been moved it can do, then wired the steppers up to my driver board (I'm using a 4 axis TB 6560, but currently only 3 motors)(I don't yet have any E-stops or limit switches or spindles, I'm just trying to get the steppers to work) like so:

Is this right? I've tried to show how I've set my DIP switches too, if it helps I can attach the entire data sheet for the driver board.

I then installed the drivers for my PCIe-parallel card, then Mach 3, and then plugged the power, steppers and parallel into the board and turned it all on. I launched Mach 3 mill, went to ports and pins and set it up how the driver boards manual says to, loaded some g-code and hit start cycle. None of the motors did anything, so I tried using the jog hotkeys. still nothing.

I then tried browsing some youtube vids, forum posts etc, (one of the reasons I chose this board was that it seemed popular and so would be easy to find other people with it) and found some different ports & pins settings which I tried. Still nothing.

The only things I have noticed are that the fan comes on on the driver board, it doesn't get at all hot (slightly warm) after 15 mins, the two LED's that I have highlighted in red boxes on my diagram come on (I think they are the 5v and 12v regulator LED's), the motors are no easier/harder to turn than when they aren't plugged in, and lastly I think there is a very faint rice crispies sort of crackle noise, which I think is coming from the steppers, but is very hard to say as its so quiet. All of these observations are the same whenever it is plugged in to the power, regardless of whether it is plugged in to the PC or Mach 3 is doing something.

So I'm kinda hoping that someone has some ideas for me... what are the correct ports pins settings for my setup? have I wired my steppers correctly? Are my DIP switches set right? Is there something I've missed?

Thanks very much to anyone who can help me out here!
