Severe servo vibration Galil AMC

I have fought a vibration on and off with my galil card driving AMC servo amps for years. Tried everything i could think of. Its been an anoyance until today. I had to shut down the machine and work on the problem before making more parts.

Before today, the vibration would only occur when the machine was sitting still. it would be a buzzing sound and you could put your hand on the servo and feel it making very small moves back and forth rapidly. Over time I've seen the issue on all four axis. An Estop (issues MO) and reset (issues SH) always calmed it right down.

Today, my knee started vibrating (axis 4) under motion and its more severe. I (of PID) is 0 on this axis. I changed it to 10 and the frequency was much lower but the amplitude was MUCH higher. I shut it down after one second.

Tommorrow morning, I'll take the servo apart and look for mechanical issues and test without the belt to the load on.

I could sure use other ideas.
