Hi, I need advice and direction. 4 Axis CNC Stepper Motor Driver TB6560AHQ Board Controller Router Mach3 KCAM4 item #251901027087 on ebay. Is this what I'd need to run Mach 3 on my machine? Would I need anything else? If I read it correctly this is a "bob" and drivers on one board. I don't have the experience to know the difference so I'm asking for help. Right now it is set up with an XPro board but I want to run Mach 3. Would I be better off with 4 drivers and a separate bob? Thanks for the help guys.
