Debugging is an ongoing process, trying to spot the idiosyncrasies of this machine and make appropriate improvements, but basically, it works pretty well now. 

Not all PCBs are made equal ...... I've had some made from some companies where the screen print has been off by as much as 2mm which makes populating the boards very difficult, especially on small 0402 stuff.
