What you have to gain is a working rotary table!! That is the goal, correct?!?
Why would the parameters change? I have no idea. Bone head operators changing something they do not know, sabatoge, or plain human error. I don't know your shop or who has access to what. I can only speculate on the information that is presented.
Your other options are to start throwing money at the problem. Change out some boards, cables, call in a tech, etc.
Check them or don't check them makes no difference to me, but you asked for suggestions, so here they are.
Good luck!
