Hi there CK, I didn't follow the link yet, but I thought I'd comment on your post here. I've attended two engineering schools in the USA, and one of them was a pretty darn good school. At both, I would have to say about 80%+ of the graduate studen

All these generalizations are non sense. What real cph you will receive depend on many factors: - paths optimization - what number of feeders are used - what number of nozzle changes has your job - how fast is the recognition for small and big part
