Need Help!- Controlling AlienCNC 1 axis stepper motor controller

[gremilRoute]

How would i go about controlling a stepper motor using the STEP and DIR of the board. The datasheet mentions nothing to do with controlling it except that it features "Two phase bipolar (chopper) pulse width modulating technology". I would ask alienCNC but their website doesn't seem to be working anymore.
Thanks for any help.

have you had any joy yet? I have an alien cnc 3 axis board working ok, maybe i can help.

I got it working for a couple of days, then i accidentally incorrectly wired a stepper motor in and blew one of the drive boards. The other 2 i had, both blew for no apparent reason after working for quite a while each (possibly the board has a really bad heat sink). I instead bought a 3 axis controller off eBay and am running it from my computer instead of using my arduino board. When googling the AlienCNC boards it turns out most people recommend against using them.

bummer, looks like i was lucky then...

what kind of set up do you have now?

here's mine:

not doing a lot yet with it, just a bit of wood engraving etc.

cheers,
