Basic Angle Beam Calibrations

I had recorded a first draft of this over a year ago but shelved it because I messed it up. Then this time the mic didn't work. If bad things happen in 3's then I guess I'm tempting fate because I hit "print" anyways. I'm not trying a 3rd time. AAAAND I forgot about setting the X-offset after doing the beam index point. Good grief, maybe that was the 3rd one.
