The trimpot on Geckodrive stepper motor drivers does affect smoothness, but adjusts microstep linearity, not the anti-resonance circuitry. Due to magnetic construction of motors varying, and due to the response issues near zero current, the smaller current microsteps tend to bunch together. The adjustment is for minimizing this effect.
