how many leads do the encoders have? I though mine were differential but I was confusing Quadrature with differential. Differential endcoders will have 7-8 outputs depending on indexing. TTL only have 4-5 outputs.
that definitely sounds like a noise problem though. It is the same symptoms I had.
Have you tried spiral wraping the wire from the power supply to the servo drives?
I only have very short wires from my caps to my servo boards but this was the first thing I did on my box and the noise problem got better but only the encoders solved the problem. After I started having problems I spiraled every pair of wires I had in the box. Unless they were loners!
edit: I also switched all the motor wiring to sheilded wiring.
