Sounds like you have a non-IQ system? If you can, get one! It makes life much easier. Costly, though! Anyway, as stated above, your best bet is to assign multiple boards to the same table top. If the two boards are 99% similar, use a full opti

Hi CKH, If the problem is on the current board type only, the problem is in the fiducials or in the CAD data. If the problem remains on all boards(different product) it is definetly a machine calibration problem. Did you try to reteach the board one
