Hey Tiller, the gantry is 2.5 inches thick, and a quick FEA in Fusion shows around 4 tenths of deflection in the gantry with a 300lb load. This is what my steppers could in theory produce with 100%...

Thanks for the tip Peteeng! I started with 400 grit and worked up to 1500 where the blocks mount, and re-indicated it to the rail. Anyway, some updates:
