☝️ Marlin Firmware is a popular open source firmware for #RepRap 3D printers. Built on the #Arduino platform, Marlin is optimized to run on anything from a modest 32KB AVR to a powerful 32-bit ARM. Created by hobbyists for hobbyists, it also runs CNC mills, lasers, plotters, pick-and-place machines….

The updated Fixed-Time Motion scheduler and trajectory planner is blowing away the previous implementation with its smooth and quiet operation. It’s been ages since we just sat and watched the printer in awe, but this is some crazy magic. #RepRap #3DPrinting #OpenSource

Realtime 100x print speed is possible, but only in simulation! Attach the Marlin Simulator to LLDB in VSCode and there's no more fun and exciting way to debug and test your improvements to our small and maximally efficient #OpenSource motion system. #RepRap #3DPrinting #ImgUI

At the moment #LLMs still can’t handle our codebase and choke on preprocessor macros and novel meta-programming. Humans are still far more adept. But we are rooting for you, brave little #AI, and we’re sure you’ll get there soon! #OpenSource

The definition of irony: Contracting pneumonia while you’re taking an extended health break. 😵 (And now I know what a “pleural effusion” is.)

Did everyone have a great time at #MRRF2025? We didn't make it out this year because #RepRap needs us to stay on the job to keep this thing going! But guaranteed we'll be there next year to represent our eternal commitment to this amazing #3DPrinting community!

We’re tagging a new release any day now. As the premier #OpenSource single-board motion system we’ve still
got a lot to do and much of it is already mapped out. Join our human effort or we’ll be forced to hand over our task list to schizoid #AI !

The content on #3DPrinting and #RepRap was exciting while we were inventing the technology. Now we’re just talking about the latest models and features and it’s no more interesting than content about the newest television. What will be the next #RepRap -like phenomenon my fellow #makers??

Hark! The beta testing period for 2.1.3 is almost over! We’ve been cleaning up, revamping, and optimizing the motion system to achieve higher acceleration and fix longstanding annoyances. Your existing #RepRap machines and #3DPrinters will seem brand new, and your future builds will be extra extra.
