You also should check to make sure you have blow off at the placing station set properly. I have seen machines with the flow control valve shut completely off not release parts properly. The parts end up in the scrap bin and the machine thinks they

Hi, Does it really matter what temp the oven runs at as long as the PCB's are profiled correctly? I mean we run boards through all the time to check profiles, so as long as that's ok, would it matter what the oven though the temps where? Regards,

We have concrete floors. We check 28 locations every 90 days with a surface resitivity meter (calabrated) and Ive never seen a reading other than 10 to the 9th

I have never seen that message before, but you should check the Z axis driver card, and the Z home sensor. Do you hear anything when the axis tries to move?
