What else do you need to complete your machine?

MX-P423-400 By AMT

2. You will need to purchase or make a router/spindle mount. I highly recommend the router/spindle mounts sold by www.cncrouterparts.com

4. You will need to purchase some type of Controller software such as Mach3, Mach4, or UCCNC.
5. You will need to purchase some type of program/design software (CAD/CAM).
