Thanks - I've not managed to find the spec on these steppers yet unfortunately so it's hard to compare to builds others have done.

People seem to suggest anything from 270-425oz for the X2, but the lower end would be fine for me to get started since I got these free. I'd only ever be doing light work and speed doesn't bother me for now.

Definitely intending to change to ballscrews but can't afford to just now. So I was hoping to achieve a cheap but functional setup before hand, so that it'll be ready automated and a big improvement when the budget allows for ballscrews in future.
