Subject: CNC Z-axis: Quill or knee?

What are pros and cons for using the knee versus the Quill for feeding the Z-axis? I realize the obvious con of much larger mass and force required and massive "weight compensating springs" for the knee. On the other hand, locking the quill will give a much more rigid system. My "Bridgeport type" mill already has built in DRO. I intend to use the DRO encoders for the CNC function. The Z-axis is monitoring the knee, not the quill. I can always switch to the quill but I like to evaluate my options before digging into the conversion. Bertho Boman Vinland Corporation in now too hot Florida
