Modder uses Nintendo Switch to boost aging 3D printer's speed by 90%, dropping 3DBenchy print time from 90 minutes to a mere 8 minutes and 41 seconds — enthusiast claims big quality improvements by using jailbroken quad-core console

Why This Matters

This innovative use of a Nintendo Switch to run Klipper firmware on an aging 3D printer demonstrates how repurposing consumer hardware can significantly enhance performance and quality. It highlights the potential for enthusiasts to extend the lifespan of existing equipment through creative modifications, impacting both hobbyists and the broader 3D printing industry. Such advancements could lead to more accessible, cost-effective upgrades and inspire further experimentation with off-the-shelf devices.

Key Takeaways

A keen nozzle-head has dramatically sped up their 3D printer using the portable power of a Nintendo Switch. Cocoanix 3D Printing shared a video earlier this week demonstrating the Switch-powered acceleration of their venerable Prusa MK3S. Instead of taking 90 minutes to output the famous standard 3DBenchy tugboat model, the Nvidia-accelerated MK3S took a brisk sub-nine minutes. Should you repurpose your Switch to accelerate your 3D printer? That, of course, depends…

In the video above, Cocoanix boasts about not just the increased performance but quality improvements. Using Klipper instead of Prusa’s custom firmware (originally based on Marlin years ago) delivers modern features like more extensive planning, advanced vibration compensation, and other techniques. As well as getting your output in a fraction of the time, “less ringing and ghosting” will be present in the output, according to Cocoanix.

Klipper is also a champ when it comes to configuration, with a simple and easily editable text file ready for tweaks. More traditional firmware recompilation techniques for the granular control here are thus simply not necessary. Moreover, while the printer’s motion‑control firmware is replaced by Klipper, the user interface is handled through the slick Mainsail/Fluidd web dashboard.

Thanks to the power of the Switch and Klipper, with the Prusa MK3S, the bottleneck stops being processing power or advanced features, and is instead the 3D printer’s hotend and extruder. Running the new Input Shaper, the TechTuber manages to push the MK3S “to its absolute speed limit: 400mm/s at 17,000mm/s² of acceleration.”

Modern 3D printers aren’t so short on horsepower

The touch screen Switch is a great add-on for the Prusa MK3S. However, the MK3S is of a certain vintage now, and while contemporary designs addressing the same market may suffer from similar processing bottlenecks, adding an SBC or Switch to a modern 3D printer may not be so desirable.

Here, instead of motion planning running on the 8-bit microcontroller on the system motherboard, the machine is enhanced by Klipper, farming out all the heavy compute work to the attached handheld console with a quad-core Nvidia SoC.

Users of devices like the MK3S usually employ something like a Raspberry Pi or connect to their laptop to accelerate and advance their 3D printing. The use of the Nintendo here is mostly stylish tech flair – but the integrated touchscreen might be welcomed by some.
