• YouTuber runs Klipper on a Nintendo Switch to cut 3D print times by 1000% on old 3D Printer May 18
Additional Context
A YouTuber going by Cocoanix has used a Linux-loaded Nintendo Switch to run open-source firmware called Klipper on a Prusa MK3S 3D printer (released in 2019), cutting a 90-minute print job down to just eight minutes.
The trick doesn’t actually require a Switch specifically. Klipper is designed to offload the processing work that standard firmware like Marlin handles on a printer’s own microcontroller onto any external device. Cocoanix describes running Marlin on a 3D printer’s microcontroller as “a bit like asking a calculator to run a spreadsheet.” The Switch just happened to be what they had available, though Cocoanix concedes “for most people, a Raspberry Pi is a better choice.”
With the Switch handling G-code processing and sending real-time instructions to the printer, Cocoanix push
