    2.2kw is the standard for a nice machine. And no need to upgrade as they are quite reliable. If you buy from reputable seller and receive GPZ brand spindle, yes, they are 4 bearing. spindle is best controlled from board. The more "auto" the better in the long run.

    Why dont you take a step back and explain your axis decisions? if you have not bought the screws and supported rails.

    First of all Hiwin 20 is enough and best for the purpose. Secondly the Z and the X/ gantry are quite more important than the long axis /Y and A/ . So if not gonna be used square rail on all machine, then better be used on Z and X.
    Also 20xx screw for Z is overkill, 1605 is best there and 1610 for the X.

    There are many threads in the forum where all is explained again and again..., so may be some homework?
