Need to probe to small interpolated bores on diagonal corners of each part blank to find part center (G54,5,6,7..), and angle of rotation when flipped to side 2. Angle of rotation to be corrected via G68 on op2. Front op1, Back op2 to align within microns when flipped. Any ideas welcomed. Normal practice in my field but probing two bores does not seem to be an option in mach 4 probing page. Watch parts. Any help appreciated.
