☝️ 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….

My 2nd plotter runs with @marlinfw.org , just like a 3D printer 😄 #penplotter #3dprint

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

We have many community resources and I am diving into release work now, so please take advantage of our many other resources! marlinfw.org

Most people just use Auto Build Marlin in VSCode. You will need to be more comprehensive in setting up your configuration. I was merely pointing out that building Marlin is relatively trivial if you have a good configuration.

The options that were modified allowed the firmware to build for SKR3-EZ. The mftest command is included in the Marlin project and it builds Marlin from the command line. The -a flag tells it to automatically determine the correct target env.

For a test to make sure everything is copacetic I just did this and got a successful build. Of course, various settings would need tweaking, but it works like a charm. The "Auto Build Marlin" tool makes it slightly more convenient.

Indeed, the Ender is often the best choice for an example because it is a reference design. If you have a config created that works for your Ender-3 with SKR-3 EZ please submit it to the project! We rely 100% on the community for these things,

"Auto Build Marlin" is a VSCode extension created by the lead developer of Marlin Firmware to provide all the tools you need in one convenient location. It's never been easier to configure, build, and update your motion system firmware!

I’ll be live streaming later today, putting some final touches to the upcoming Marlin 2.1.3 release. This version will be tagged on Friday and we’ll patch up your reported issues in followup point releases. #3DPrinting

Change nothing else —only the MOTHERBOARD— as a starting point. If it builds and works you can then make your own adjustments. Some examples may override a pin or two so watch out for that. This helpful page shows just the non-default settings in isolation: github.com/MarlinFirmwa...

Build examples are for specific printers, not boards alone. Take an example for the given machine and just change the MOTHERBOARD to whatever you’ve got.

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.)

I just need to take it easy (and sleep a lot) for a little while, then I’ll be back on the project full-time!

With so many changes in our industry, now is Marlin's critical moment.

Our sponsorship is in steep decline, yet our workload is holding steady.

As we continue support and development we need your help now more than ever!

We are continually improving Auto Build Marlin which builds Marlin with the push of a button. For those who prefer to skip the build, we provide pre-built binaries (and concise "Config.h" exports) for all contributed configurations at github.com/MarlinFirmwa...

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??

Canceling noise and oscillations allows for higher speeds and results in cleaner prints. Check out Tom Brazier's blog for background and insights into his clever ZV Input Shaper … which even runs on your old 16MHz AVR processor!
