Can you wire a three way light circuit using two three way dimmer switches. One on each end. Feed on one end and light on the other end. With two dimmers, I can't get the circuit to work. If I remove one dimmer and use a normal three way switch on the fee end, circuit works just fine.

Any particular reason you posted this 4X? Read the dimmer instructions for 3 way, you can only use 1 dimmer per circuit.

With regular dimmers, you can only use 1, Another type mentioned was on another post.
Insteon 2477D works well, need 2, can have as many as you want, They Make a Hub that allows control by App/phone?
