Here's the whole trick:
Carefully set the stop collar on the diamond shank to the tip just skims the wheel. Then, with the grinder
running (of course) just slowly run the point back and forth across the face of the wheel. The diamond will shave
off the high points, and using the tool rest as a guide keeps the tool steady. Holding the dresser by hand tends to
let the point follow the wheel, making it harder to get it running smoothly.

You might have to readjust the stop collar and skim the wheel more than once, just make light cuts
with each pass, and eventually it'll get smooth and concentric. Both the wheels on this unit took
two light passes, and are now damn near perfect. You can hear that it runs smoother, and there's less
vibration on the part you're grinding, with a lower tendency to get "kicked" away from the wheel.

However, on this particular setup, a bit more work was needed to
eliminate even more of the vibration...
