THanks.  Look at the pic.  The green center axis are not square to the leg.  Positioned like this with  a y offest of 11 degrees I can get the leg to move up and down on the X axis without twisting either on z or y so it works. My question is why can I not re-orient the center green lines to be "sqaure" to the backend of the leg as it was originally?  When I do - the leg rotates in along x AND y which I don't want.  I hope that helps....
