Creality Ender 3 S1 running Klipper - 150mm/s, 3500 acceleration

This is the Ender 3 S1 running Klipper, printing at 150mm/s, 0.15 mm layer height with 3500 acceleration (realistically, it&probably printing at 100mm/s). This is probably the maximum printing speed you can achieve with the stock configuration. The main limiting factor would be the hotend which is not able to keep up with the high flow rate.
