Yes, AM changed their #25s at some point. They're now thinner and no longer chamfered, and we're having systematic issues with CNC notch defects. There was a bunch of talk earlier this month about it, but it was never resolved into a different supplier. We're currently looking either at fixing the bolt pattern and bore on the less expensive RobotShop ones or crossing our fingers and trying to lathe a chamfer on AM's thinner ones. Wondering if anyone found a different solution.
