its not that big but they did come with up to a 5hp motor depending on original option taken.around 150 x z around 200

things are a lot better now i have centroid and an encoder on the spindle compared to mach3 before . But i think servos would be a better option and give a bit of a comfort blanket for accuracy if I'm not mistaken .
So if 750w looks more than enough from peoples experience that's fine i know what ball park to be in .
if anyone has links from any vendor they have used and trust that would be great

cheers
