Hi All
This looks like a great project that your buidling here and a nice way to do it as well.
I found these linistepper drvers online http://www.piclist.com/techref/io/stepper/linistep/index.htm
I was wondering if they are compatible with the code that your writting they seem to use a few more wires than a chopper driver but from what the website says they may provide smother motion than a standard stepper driver
Im intrested in building a rotary table to begin with and am happy to help out in anyway that I can. Im not a strong programer I know just enough to get myself in trouble. I have furniture and product design background and some skills with graphics. So let me know where I can help to give this a nuge.
Cheers

The wiring has nothing to do with the way the driver functions, but for the type of motor it drives. This driver is used for uni-polar motors, which are abundant and work fine.
It is a driver that takes step/direction inputs, so it will work just fine with the engine.
There are less expensive bi-polar drivers that work just fine, and many of us are using them, including the Pololu drivers: http://www.pololu.com/catalog/product/1202 (http://www.pololu.com/catalog/product/1201 is cheaper, and smaller, if you want to supply your own voltage regulator.), and the Easydriver: http://www.sparkfun.com/commerce/product_info.php?products_id=9402
I can't speak to the quality of the linistepper, but people on CNCzone like them, and they're open-source, which I like to support. However, my caveat here is that if this is your first electronics project, I would suggest getting a pre-assembled driver, as debugging issues with a circuit is not necessarily a fun way to start. And debugging a high-current circuit is much less fun =)
But, if you like the drivers, they should work just fine from the OpenMoco perspective.
