yes i did DaveK and sorry for not posting my findings. thats what led me to chainge the pots. even when i was not moving the pots it would chaing just a little. the program it self did not work thow 1 of the pots would more 2 servos and one of the other pots would more 2 servos and the last 2 pots did nothing. lots of shaking. something was wrong with the code because i was never getting that much shaking and i have always had 3 servos working right.
when i started this project i was only using 2 servos for 1 cam and that all worked fine now i added to more servos for cam number 2 and thats when the trubble started. so the pots that i replaced were the 2 new ones i had added.

You may need to add decoupling capacitors. Try some 0.1uf ceramic capacitors across the servo power rail. If you have long wires connected the servos put capacitors at both the servos and power supply ends.
is this what your talking about? http://cgi.ebay.com/50-pcs-Ceramic-Axial-Capacitors-0-1uF-100nF-20-50V_W0QQitemZ290328838783QQcmdZViewItemQQptZLH_DefaultDomain_210?hash=item4398f2827f&_trksid=p3286.c0.m14
is there any wrong way to install them?
could you please tell me more about this?
