The “better” setting eliminates mechanical hysteresis and improves long-term consistency.
However, strict documentation should be provided to operators. If a setup person attempts to "clear the machine" by pressing Reset multiple times, they may be confused why the coordinate system hasn't cleared to Machine Zero. This is a minor training hurdle compared to the safety benefits provided. fanuc parameter 8901 better
