Tuning will vary based on the table mechanics and motors. One person's settings my cause your table or motors to break into violent oscillation. When you get everything hooked up and mounted turn the current limit full sup and set the gain and damping at at 11:00 o'clock position.
Turn the gain up until it gets unstable. Turn it back down and advanced the dampening a few degrees and turn the gain back up again to instability; keep walking it up. After you get it to a point that has good "stiffness". Run the axis through several rapid moves with direction change. That will tell you if you have the gain too high. Too much dampening can cause problems so it's a dance with both controls and they interact.
Unless you know what you are doing with a scope and don't mind mounting remounting the drives (to get the covers off and on), then tuning by hand is the best way.
It's not so critical that it could cause any damage and you may find the default 11 o'clock starting place is fine. You have to have them on you machine to tune them correctly. You can do it sitting on a bench but it's not much better than just running them at default.
For those size motors I turn the current limit to about 2/3 fully clockwise.
