Help with hed 3 cassette/wheel wobble

I am new to working on my own bike and I have hit a problem with my rear wheel.
I bought a Hed 3 tri spoke rear wheel (clincher) off of eBay. The wheel came without a cassette.
I put a Shimano Ultegra HG CS-6500 9-speed on the wheel. The shifters are Shimano Dura Ace bar-end and the derailleurs are Shimano Ultegra. I used the skewer from my Mavic Ksyrium Elite rear wheel.

When I put the Hed on my bike, it looks like the cassette and chain wobbles when turning the pedals. The wheel itself doesn't wobble (the distance between the brake pads and wheel doesn't change).

Is the wobble normal? Have I installed the cassette wrong? Is the cassette incompatible with the shifters/derailleurs? Bad wheel?

Thanks in advance.

I've been told that a little wobble isn't really a big deal. If it's causing your drivetrain to be noisy, poor shifting, etc, I *think* the fix is to get a new hub, which basically means a new wheel if you're not into wheelbuilding.

Ok, I hate to revive a dead post but it looks like it just sort of died and I actually have the answer. First off, DON'T take the freehub mechanism off of the hub, if you do you'll have to mail it back it HED to get it fixed. The wheel is most likely fine and they NEVER untrue (or so I have been told, and I have no reason to questien that). Trueing is factory done by putting little (0.001") shims in there. This sometimes makes it look like it wobbles but in reality the wheel is completely true and the actual distance is correct. If you are still worried call them up (The phone number is on their web page) and ask.

There should be NO Wobble in the cassette. There should be no play in the cogs on the cassette. This should all be tight.
What you are missing is a 1mm spacer that needs to go on the hub, before putting on the cassette.
Your local bike shop should have these around. When you lock down the cassette, it should be tight.
This seems to be a very common issue with the HED 3 wheels.
