I've been reading up on feed speed and all of the discussions begs this question. If the feed rate knob is a 'maximum' and the computer will slow the feed down as needed regardless... y not just set it to the highest and let the computer idle it back as necessary? I understand that on stove temp guys want to regulate things using the feed rate but if on room temp you're only limiting the speed y not open the valve and let the computer do the rest as needed?
