Ok, after looking at this from many angles, and reading so many posts on many sites, I ordered a 48" X 48" ProCNC. All the hardware from AVID and all the electronics, motors, and spindle from Gary Campbell. running Centroid Acorn.
And I have added the rotary from AVID too. At this time I have the majority of the hardware assembled and ready to run, and I am about 3/4 done with the electronics. I have powered the controls up and moved the 3 axis. I will say it has been an adventure to this point, and I am now doing some fine tuning of the hardware before I finish the electronics. The basic hardware seems to be very good, and I am happy with the electronics package.
I am not rushing through this, but using what free time I have to complete this.
I can say without a doubt, that the support I have gotten at this point has been great.
