Wasteboard Adjustment?

Anyone around here have some decent ideas for levelling Carvey’s wasteboard?

Since I received the machine it’s always been a little off. A .001" pass won’t even make contact with the stock when I’m carving near the smart clamp, but in all directions away from the clamp I’ll be down into the stock as much as 1/16". The wasteboard itself is in good shape, and my stock is clean, flat, and clamped with even pressure all around, so it gets pretty aggravating.
