Just have to make sure it stays very clean. And is the plate just riding on ball bearings against the bottom of the enclosure?
Yes, you do have to keep chunks of filament out of the gears. In practice, I'm not that tidy and most of the time any debris gets pushed along the pinion rod and out of the way. Only once did I have a mis-print due to a large chunk of filament in the gear.

Also, the build plate has feet in the corners that normally glide just above the flat surface at the bottom of the enclosure. Normally the build plate does not want to tip, but if you have an off-center center-of-gravity, one of the feet may touch down as you move to the extreme X-Y positions, but the transition is smooth and not noticeable.
