Recommended controller and stepper drivers for new build

[Andrewg]

These are what I use on small machines like this and they work great. I've fitted loads of these on small machines like what your building.

What voltage do you drive these at, as I see they are 50v DC?
I assume as closed loop gives you almost 50% more power over open loop the lower voltage is less of an issue.
