TVM920 PNP Down Camera Not Finding Mark Point

[chris2006]

Hi All

I have a TVM920 pick and place machine which is working OK apart from the down camera not locating the mark points

I have adjusted all the settings in config but nothing improves

The very occasional time it see's the hole in the PCB and auto centers but in most cases I have to manually align.

Has anyone else had this problem and found a fix?

Thanks
