I switched to a Hemera direct drive hotend, there are better options now, but you may not need that depending on what an S1 has OOB.
The big change is the enclosure, doesn't have to be fancy, mine is a couple of IKEA LACK tables with some acrylic duct taped on and a door duct- taped on only one side.
I upgraded from Marlin to Kipper and tuned for resonance which lets you achieve much better speeds and quality than a stock E3v2
