I have been using a laser tracker for a few months now but have not needed to do any bundle alignments. That time has now come. Any tips, advise, guidance or info would be greatly appreciated. Im using a Leica Absolute Tracker AT901
More points are better.
Make sure that the angle between the bundles you do is not a shallow angle. Near to 90 degrees is best.
Don't forget to put in a probe comp OFF command before the Bundle and a probe comp ON command after. You wan to measure center of ball for the bundle.
Use the 1.5" ball
