Testing the Spindle Motor and PSU I got. Good to see they are not  duds (so far), but I will likely have to buy another three phase motor  that isnt limited to the built in ER8 collet chuck. The interface seems  to indicate the correct RPM even without Hall. So that's good. Here are  the links to what I bought;

(48v 600w)

And this is what I will probably buy at some point so I can use 1/4" bits, but with the same 600w driver;
