"I have the scanner programed to lock a crop box at 41.5mm x 41.5mm. I then just drag the box to the exact position, thus centering the chip perfectly. Or at least near perfectly."

I dont know how to tell the scaner where to scan on the bed, I just put the chip in a corner. It is stopping me from flipin my chips but I have been very busy !!

Thanks for the help, wish there was an easier scanner to buy like that business card one!!
