This is a very solid and well built cnc. Works like a charm. Owner's Manual, and Oliver USB setup included. 15,000 rpm ...takes 1/4" shank bits. See below website link for all specs. I use VCarve Desktop Vectric software for all my designing, but any g-code software like Carveco, Carbide Create, Fusion 360 etc., will work as well. Just create, file to a usb and plug the usb directly into the Oliver and run your project. Would consider a trade for a good planer. I need to make room in my shop so make me an offer I can't refuse.
