I am trying to use a G68 rotational coordinate system on a VM5 OKK mill with a Fanuc 180i control. I am storing the angle in variable #550, and calling it with a "G68X0.0Y0.0R#550" line. It works great when using offset G54, but when I try to use any other offset (G55, G56, etc.) it wants to refer back to offset G54. I have tried moving the placement of the line all over in the code (before and after the offset callout), and nothing seems to fix it. Is this a parameter issue, or what have I got going on? And help would be greatly appreciated!!
