After having my Series II machine almost 6yrs I finally did a Series 3 upgrade!!! Since I had the machine setup/ready to move back to my shop in Washington it just seemed like a perfect time. Holy smokes what a difference in the way it runs, it's quieter and I swear the surface finishes are better but its probably just my imagination. The Z axis rapids from 65 to 90 seems blazing fast and the first thing I did was ram my Haimer into my part when doing a Z touch off. My fault for not paying attention.
Anyway I am kicking myself for not doing this years ago.
