It is certainly small and light enough that shipping it back shouldn't be too much trouble if they'll fix major problems under warranty. It's being pitched as a "consumer" machine so they'd better think about getting that system set up and in place for the wave of tickets they'll end up getting.

That being said, I've been studying the mechanical design of the thing for almost a year now and with a very low part count, about the worst mechanically I can see happening is breaking a guide rod or a belt. Anyone on this forum is likely competent enough to be able to repair it. Getting all 4 screws on the H-bridge timed to one another properly isn't critical if the bed leveling software works as promised.
