When you are running in micro stepping mode, the stepper it behaving like an AC motor. Missing a micro step is not a problem if it occurs between the motor and the driver (but- see below). If it occurs between the controller and the driver, lost is lost.
To easily loose a step between the motor and driver, you either need to open the wire to the motor or short it out. Either way there’s a lot more than just the micro step being thrown out. You are abruptly taking the motor current to zero. That’s not the same as simply holding the previous value a bit too long. Your motor will *not* be happy when you suddenly do that.
I would not start with the controller at all. Electronics are (relatively) cheap and flexible. I would work out the mechanical side of things first. That will get you to speeds and torque needs. That drives the motor size selection. With any size you can then pick a voltage and current combination *along with* a driver. Then the controller will come into play.
