Noisy Banebot 20:1 Planetary
We built up six 20:1 Planetary gearboxes, and found one of them to be slightly noisy. Upon disassembly and inspection, we discovered that the 11-tooth pinion gear was cracked through. It's difficult to see on the picture, but it can be seen fairly clearly if you're looking for it.

Re: pic: Noisy Banebot 20:1 Planetary
It's because the BaneBots pinion gears are bored for a tight interference fit on the the BaneBots motor shaft. The FP (and the new AndyMark 500 series) has a knurled shaft which is just big enough to crack the gear.
