** Step Motors & Controller board **

 this cutter is 4-axis, it means it needs 4 step motors and controller board. So I choose the 'Nema 23 CNC Stepper Motor 2.8A 178.5oz.in/1.26Nm CNC Stepping Motor DIY CNC Mill' and 'TinyG CNC Controller Board v8'

** Drawer slides **

 this cutter is moving device, so it needs Drawer slides to improve moving. I buy the 8 drawer slides. the half of them is 18inch for up and down, and the half of them is 24 inch for front and back.
