So, how'd you get your machine apart, OM? I'm thinking of either trying to sand down the pins, or drill out the holes, before putting it back together, so I don't have to go through this the next time. It's not clear to me what value they add over just the bolts. I know we don't want the steppers flopping around adding to backlash, but I would think the bolts would be enough to prevent that. Certainly snug (not "nailed") pins would be adequate.
