The steppers will generally only lose steps if they're tuned too close to their maximum speed and acceleration from my understanding and reading of Jazz's posts. There's plenty of people on here using twin setups and not many posts to say they're losing steps and racking the gantry. I'm in the same situation as you regarding the twin vs single stepper and I'm leaning towards the single Nema 34 with a different driver. The AM882 will not drive the Nema 34 with any sort of speed, 240V drives are best for them but they are more expensive! I'm going to use my spare 3.1Nm Nema 23 stepper and driver for a 4th axis when I get the Nema 34....
