There was an initial wear-in period in the anodizing. Nearly all the wear you saw occurred in the first few cycles. We ran an accelerated test platform which ran the gearbox for several hours in full speed forward to immediate full speed reverse cycles, in both gears, and experienced no significant wear on that platform after the initial wear-in period. Additionally, the competition robots exhibited no failures or significant wear over several competitions, and likewise with the practice robots after probably over 100 hours of use. These aluminum gears are actually stronger and harder than off-the-shelf steel gears (such as Martin) you can buy.
