I recently picked up a used GSM-1, 1994 or 1995 vintage. I'm in the process of setting up my first product on it - everything seems to be going well, however there's a constant inch or so offset on the X-axis. That is, when the board slides in, it's looking for fids on the next circuit in the panel. My board dimensioning is good, placements are all right, fids are verified against cad data+offsets, etc. Everytime I try something, it ends up with the same offset as well. Is there some sort of older-style board handling issue that I'm missing?
