A few other tidbits. I plan on using 1/2-10 5 start acme screws. Not sure of the drivers yet...I bought the motors from us.stepperonline.com and Bo told me they have a brand new professional (not hobby grade) version of the TB6560. The driver isn't listed yet on their website. I just might give that a try.
Ahead of the drivers will be Windows 10 to an Arduino Uno running GRBL. This setup has served me well with the Shapeoko2.
