I'm looking for the philosophical description of what Constant Velocity setting does for your cutting? 

Or better yet a practical description would be great too.

Does CV "off" interfere with the accelerations in Motor tuning?

Does CV "on" induce errors in accuracy?   

thanks in advance
Dave

These are a few really good threads on that. Look at the bottom one first.
