My servos sometimes move a bit even when no code is running on the cRIO, even when no power goes to the cRIO. The move is a small glitch of a few degrees.

Check your servo connectors at both ends. The servo cables may not have good strain relief, and you may be able to provoke this by wiggling the cable. If so, replace the servo or the cable.
