The closed-loop stepper system is far better than the Standard stepper system for a few reasons, provided you buy the right one.?

Basically there are types of closed-loop motor, 2 phase or 3 phase, 3 phase is the better type. They give a smoother movement because the Step angle is lower, usually, they come with either 1.2deg or 0.9deg compared to 1.8 deg found on standard 2 phase hybrid stepper. They are also more powerful and less prone to resonance.

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.

Don't go with USB, Ethernet is much more reliable and fitted to most PC's. USB is flaky and gives all sorts of troubles with electrical noise.

You are correct not to Skimp on the electronics, it's the heart of the machine and the single biggest cause of trouble on many machines that use low-quality electrics.
I'll eventually go this route I reckon:

48V power and driven by a UC400eth.

(well, if I can make any £ that is).
