Hi I am in the process of finalizing design of my 1st CNC Router: Z-300mm, Y-700mm, X- 900mm.

My current design has 2 stepper motors driving 2 ball screws on the X Axis, the linear rails/guides and bearings have all been ordered. All of the Extruded aluminum has been ordered as well.

Before I commit to buying the Stepper motors, drivers, and the like I am uncertain if it would be best to use 2 Stepper motors and a 4 Axis board or 1 Stepper motor driving both of the ball screws via a belt arrangement.

Does anyone have experience with either? any recommendations.
