You very well may have waived your lack of adequate service defense by filing a motion in response to receiving the ticket. For future reference, ask for a free consultation with a criminal defense lawyer before responding to a photo radar ticket in any way.
Generally, the act of showing up to challenge jurisdiction does not waive the challenge to jurisdiction.
Lastly, always make sure you are citing the right set of rules. You might want to consider reading the Rules of Procedure in Civil Traffic and Civil Boating Violation Cases.
It can be very difficult to represent yourself when there are so many rules and legal principles at play. I recommend calling a local attorney to assist you.
Best of luck to you.
