I still have to upload my latest pictures but thought Id at least post these tonight.
I have the machine running now - Its running great though I still have some initial fine tuning to do.
Below are a few pics taken last week before the Z axis motor was mounted and I was running the X - Y axis while testing and setting rates, steps per inch, limit switches etc.
By the way for those who didnt see my prior thread
