I have an ender3 and I wouldn’t have dreamed it would go this fast. I was looking at putting a new direct drive on it to go faster… something like I read about here. What hot end is needed to go faster? I still have the stock. I’ve upgraded to a dual geared extruder and put a better fan setup on it and the blue tube. I’m happy with print quality at the moment, but 40 is way slower than 180…
