Hi, the question is which geometry is more stiff and why? Lets say same working area (small), same machine bed material, same machine size. For metalworking. From my observations in diy machines the main difference between two is z axis stifness. Usually vertical design have more stiff z axis and space for installing low rpm spindle+motor. Bridge design usually mean less stiff z axis and high rpm woodworking spindle. Does that mean verticall design is better in terms of stiffness?
