Jittery servos

Lynxmotion Robot Arms

Hi,

When using the SSC32 controller and coding a simple sweep loop on the Arduino (communicating via direct TX connection),
the servo movement on my arm (AL5D) is full of little twitches and the arm does not stay in one place even when movement code ends and it’s supposed to.

I’ve tested the servos using direct connection to the Arduino and they seem OK.
Also, there is no special weight/pressure on these servos. just lifting the arm itself. I am using a spring, as instructed, to take off some of the pressure,.

Would anyone have an idea what’s going on?

Thanks,
Zvika

Can you post your code ?

How do you have the servos powered? Inadequate power is often the root of many servo issues.
