Overview
- YouTuber Cocoanix showed a Prusa MK3S cut a standard 3DBenchy from about 90 minutes to under nine minutes, with one run clocked at 8 minutes 41 seconds under SpeedBenchy rules.
- Using Linux on the Switch, the setup pushed the printer to reported peaks of 400 mm/s speed and 17,000 mm/s² acceleration in a stress test.
- Klipper moves heavy motion math off the printer’s microcontroller to a general‑purpose computer, which enables input shaping and more precise G‑code timing for cleaner prints with less ringing and ghosting.
- The video and coverage note the gains were capped by the stock hotend, extruder, and cooling, and a bedslinger Y‑axis also nears its physical limit at these speeds.
- Reporters frame the Switch as a clever proof‑of‑concept, with a Raspberry Pi or similar single‑board computer recommended as the practical, safer host for most users.
