Hi Bryce, most people have the misconception that it's all in the wrist, in fact it is not. Though it plays a role in your over all serve, most amateurs forget to use their entire body including their feet. Wrist work is only the the final act of your service. Serving with your arms and wrist will not get you the ultimate spin on the ball. Rehearse your serves without the ball 1st, and try to use your body. And once you start using the ball, try not to toss the ball too high. Get your actions right 1st.
Your toss is as important as your serve too. Pros always toss the ball into their bodies (amateurs toss in front of their bodies). This is to get maximum ball dwell time on the bat, which means maximum spin. Tossing the ball parallel or in front of you will result in minimum dwell time, coz otherwise you'll end up serving on the table, which will be a foul serve.
Good luck, and happy training.
