Yes I'm not worried about servo following error spikes. But I'm shaking my

a friend's okuma can go at 40m/min without shaking. Which is amazing to
watch. They are both similar size
Well, do you have encoders on this machine that read back to
LinuxCNC? if so, you can graph the velocity of the axes and
see if the servo is operating with stable response, or if
you have oscillations. You may have the MAX_ACCELERATION
parameter in the .ini file set too high.
