Hello,
I'm running a Fanuc 21i-TB control (cylindrical grinder). I want to rapid either the X and C axis or the Z and C axis at the same time for cycle time reasons (orient the C axis for loading at the same time as my retract or safety move).

When I try
G0X10.C180.
I get alarm 130 Illegal Axis Operation
This is a grinding machine with C axis interpolation capability.

Would anyone have an idea how (or if) this is possible. Seems pretty straight forward to me but....

Thanks!
