Hi there

I am trying to put together a 2 meter by 4 meter 3 axis wood cutting CNC Machine, to power It
I am using 4 step motors 45 kg/cm each. I am using helical rack and pinion system for my 4 meter long
Axis (Y axis). Here is my question: Some people have told me that I cannot Spring Load A Helical Rack and pinion system, What I want to know is that, How true is this statement?
