This is my point unless you have the tools and knowledge to use them then it's better that you don't limit adjustment and instead lock it down when setup.

As you probably know Mr. Enstein comes into play when setting up a CNC machine.? Any adjustment usually an equal and opposite reaction somewhere else and you soon end up chasing errors around the machine. This is when you appreciate the adjustment you built into the machine, esp on large machines because small errors get big very quickly as it gets wider and longer.!
