Without seeing your code, there is not much we can do to help. If your servos just jitter (constantly jerking back-and-forth), you probably have more than one servo node for a single servo and it is trying to hold several positions at the same time. You will need to rewrite your program to use a single node for each servo & control the position fed to it, or use something like gweimer/servo/servo-enable to only enable one node for each servo at at time. The down-side of the latter option is your servo will just free-wheel if all nodes for a servo are disabled, and your arm will probably collapse.
