Frustrated with mine. Alignment becomes off no matter how centered it is at the beginning. The machine goes through different brands of skates (CCM and Bauer) and different steel (Bauer, SpeedBlades, Stepsteel, etc.). Every other pair, I need to re-adjust the centering wheel.
Maybe the clamp or something is loose? Is there anything to tighten?
Edit: I check the edges with several edge checkers and even have an HDI gauge. I know they are off...
