One of our GSM machines started having an issue with "spitting" parts onto the board / blowing them around. I determined the problem be that spindle #2 on our flex head is not touching the parts all the way down to the board. It is stopping just above the board and then the air kiss blows the part away.
I adjusted the height of all the spindles using the jig plate and mpf nozzles. I adjusted air kiss and cleaned the filters in the air valves. There does not appear to be any resistance in the linear slide action.
Any thoughts on why it would not be putting the parts all the way down?
