The three considerations that put the kibosh on CNC are cost, space requirements for a machine that's not a toy, and the learning curve.
That being said, my preference is for servos because they are much less likely to lose a step. Our ANA Express has servos and runs much faster than other cutters we've had that had steppers. My POS Sherline mill has steppers and is seldom used.
If you have any specifics about a lathe that has a CNC controlled compound for the tool holder, please enlighten me. My search for such a device turned up empty.
Thanks
