Best guess, not knowing specifics of error, would be a vision system error... connection issue wrt camera. Does system respond properly (prompts to raise / lower head) upon reboot? Specific error information would help in troubleshooting. DEKHEAD

2 fiducial alignment vs 3 fiducial alignment , any opinion ? When do we actually need the third fiducial for alignment ?

Offsets are there to for an alignment change over the entire board... alignment weighting is, essentially to account for imperfect match between stencil and board, and will allow you to concentrate best alignment to a given portion of the board (give

how helpful is it to use alignment weighting over fiducial offsets ?
