Benchmark with PCIe Gen 3 enabled on a MakerDisk 512GB 2242 M-Key M.2 SSD: | Benchmark | Result | | -------------------------- | ------ | | iozone 4K random read |...

A few notes from use: - Temps are good, the hottest IC is right next to the fan cutout, so I don't think cooling is an issue. - Coil whine:...

I wouldn't recommend running inside the official Pi 5 case if you want good thermals—just like when running _without_ PoE, the case's airflow is not amazing, meaning the fan ramps...

 My S1 has the STM32F401 chip. It looks like [older S1s had a different chip](https://3dprintbeginner.com/how-to-install-klipper-on-ender-3-s1/).

Another couple options to test out include: - [Klipper + Fluidd or Klipper + OctoPrint with KIAUH](https://github.com/dw-0/kiauh) - [Mainsail](https://docs.mainsail.xyz) (sponsored by BigTreeTech) Article comparing the three: [Mainsail Vs. Fluidd Vs....

I have given away the S1 to my Dad; if he wants to do Klipper he can, but I figure he may just enjoy printing with the stability of officially-supported...
