According to IPC-7351A, the optimum fiducial is a solid circle with a minimum of 1mm diameter, but can be up to 3mm. There should be a solder mask clearance a minimum of 2x the radius of the copper circle. So the minimum fiducial size is 0.040" with

I was hoping somebody knew how to do this. My method was to place parts at 0 and 180 degree rotation, and adjust head offset until the parts were in the same position at both rotations. Then, I adjusted the M.A. station offset to zero in on correct
