Few MPCNC machines use spindles. Almost everyone uses a router with the Makita 700 series or clone being the domanate choice these days. The Makita router has similar power to a 1KW spindle. There are machines posted to this forum that use a 1.5kw spindle, so it certainly will work. Steve’s build has a 1.5kw spindle, so you could reach out to him for any suggestions. In the US, there is a substantial cost increase between a 0.8kw and a 1.5kw spindle.
