EMC 5 Axis Freqmod PID tuning.

Hello
Does anyone have some notes on PID tuneup on stepper motors on 5 or 6
axis routers setup with freqmod.o??
Here is my setup: stepper motor drivers running at 400steps/rev, 80
steps /mm for emc, max speed 15units/sec. When in G0 or G1 mode,
running anything over 60mm/sec I get a nice clean run. However once
interpolation kicks in, if a axis has to move less than >>60mm/min I
get grinding and oscillation, without any movement. I'm trying to play
with P= value, It helped by Still not perfect.
Did anyone experience anything simular...??? Please advise if you have
any suggestion at all. Thanks in advance.
