The nr1 imporant piece of gear is the motion controller.
The Pokeys for example, with hardware MPGs ! and thats crucial, move my machine with an MPG as well as a 100 grand Haas.

The MPG is wired directly into pokeys, no USB.
MPG wheels cost about 30€ each, and I put one on every axis of every machine.

Pokeys supports 3 at once with Mach3, and will likely support more (they sort of tole me they can).
CSLabs also told me that they can support dedicated MPGs.

Trust me, dedicated wheels like on a lathe, where the same MPG, in the same position, always moves the x axis, is the dogs danglers.
Just like manual, but clean, fast, 10x more accurate, perfectly repeatble.

Important point !
A usb MPG cannot be good as .. ! Because the USB has variable latencies (to 1 ssecond 100.000 less).

On a Pokeys, the engine runs at 125 kHz,
so every 0.01 ms, it checks if it needs to move an axis.

This makes it "feel" like its solidly connected to the machine.
Huge difference.
