I'm not getting an association between global and local fids on our Universal Lightning and In-Line 7 machines. The machines find globals just fine, then when it moves to find locals, they are not always centered in the search box (sometimes nearly out) which results in manual alignment. Any ideas on what I am doing wrong in the program?

I assume your global fiducials are on the panel, but outside circuit area. If you circuits are not placed exactly as in the program, globals would be located, but locals won't. At least, older UPS versions work like that.

P.S. By the way, as I can see, UPS 8+ has ability to check circuit offset locations (see Perform Circuit Offset Inspect section in you operation manual)...

There are no circuits/offsets - it's a single board.

We have yet had the need to use local fids on our boards you must be putting down pretty fine pitch parts that are needing the acurcey if it is failing fids that are within the search area then maybe its somthing else size our lighting it should find fids in the search area if its not finding the fids outside the area maybe make the search area larger. our try running without the local fids and see if it will place them ok. good luck I hope we don't have this problem if we start using local fids

Thanks for the input. These are 80 pin fine pitch connectors on arrayed flex circuits. We have found from experimenting there is really no good alternative but to use local fids. I found what I'm doing wrong - I needed to move fid finds and corrections in the order list as the global corrects did not precede the local finds. You used to not really have a choice on GSM's; the new UPS is flexible in allowing you to place corrections anywhere you want in the order list and it can confuse. It's a different train of thought from the GSM days for me but it's making sense, now.
