A maker ran Klipper firmware on a jailbroken Nintendo Switch to speed up a Prusa MK3S 3D printer. Klipper offloads complex motion processing to a faster general-purpose CPU, freeing the printer's microcontroller for low-level motor control. Using techniques like input shaping, the Benchy benchmark print time dropped from 90 minutes to just 8. While a Raspberry Pi is the typical host for Klipper, the Nintendo Switch works as an unconventional alternative.
