I have the same problem too. I have tried auto tuning the PID settings, reuploading the firmware, checked the connections and swearing at it. None of the things made a difference.
At the moment I have to preheat the nozzle to 3 degrees above printing temperature, let it "stabilize" there, and then ...

I can't seem to find any specifications on the lead screws used on the a30. I have just bought one, and it has been a fight to get it running smoothly.
The lead screw are not straight, which gives me all kinds of trouble the first 100 mm of a print. I am really desperate to get some new ones on it ...
