But in the REAL world where the part hits the board, all the software in the world can't predict part size descrepancy, polarity descrepancy, thickness error, or board tollerance errors.

But are they virtual jobs?

You may call a few used machine people. They may have them or know of a company that is going under and looking to get rid of them. Also try E-Bay.

Does he look at the board under a Mantus and mistake vias for solder balls, get mad and walk away? Mine does.

HOW did you change the temp? Stay that course till you achieve the temp you need. Try slowing the conveyor as well.
