A couple of beginner questions... Profile sizes and cutting area size.

[NordicCnc]

The machine in the picture uses a single screw and as a cutting area of about 600 x 1000 if I recall correctly. However, I've built lots of machines with this design up to 700 x 1250 cutting area using single screws. If you wanted stronger machine at the same width/length say for cutting mostly aluminum or Hardwoods with heavy cuts then go with twin motors every time.

What about the raised gantry for the machine in the picture? It would become way stiffer with raised Y-axis, e.g. with profiles and then then X-axis would me mounted straight onto the frame. This would require 2 ballscrews on the Y-axis too.
