Tried both but no difference, also tried various combinations of the suggestions, axis of rotaion as x, y etc. In the settings page it is called Rotation Diameter rather than radius, tried values for radius and diameter but again no change.
Tried running a job but the A axis just rotates contiuously and the image of the toolpath shows nothing meanigful.
Can't help but think it's close, but one small thing wrong?
