Just as a tell all, I have pretty powerful servos that are near the limit of the 8i20's, I was having trouble setting them up and wasn't able to keep position when rapid traversing. The simple remedy was
change from 1:1 to 2:1 for x and 3:1 for z. It is all belt driven anyway.
This ups the motor torque and with the fanuc motors i have, speed isn't much of an issue.
