Marlin Firmware
@MarlinFirmware
🤖 Marlin is the world's most popular firmware for 3D printers. Used by Prusa, Lulzbot, and many more! ❤️ Support our work! https://marlinfw.org/donate
For the most up to date announcements about Marlin and promotional reposts of your amazing #3Dprinting and #DIY projects follow us on #Bluesky and #Mastodon! We will continue to post here but with lower priority and less gusto.
Every #RepRap machine can benefit from well-tuned Input Shaping! This OctoPrint plugin makes the process much simpler and provides a vital UI component in the evolution of Marlin motion control. #3DPrinting github.com/navaismo/Octop…
Our classic YouTubers have all moved on to bigger/better. So where do you find your best online content these days related to hacking together a motion system, plotter, laser cutter, hangprinter … out of scraps … in a cave?!? You know… where the magic happens. #RepRap
Have fun at @OpenSauceLive everyone! We won't be attending this year, but when you experience those #OpenSource vibes and feel the inspirational winds of the #RepRap Revolution at your back you'll know we are there in spirit!
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! marlinfw.org/docs/developme… #3DPrinting #RepRap #OpenSource
⭐️ Auto Build Marlin 2.1.75 provides some new and useful things… 📝Config Editor: Updated for Marlin 2.1.3-b3 compatibility. ℹ️ Info Panel: Documentation Search for quick access to useful knowledge when you need it! 🔗github.com/MarlinFirmware… #RepRap #3DPrinting #OpenSource
Marlin 2.1.3 beta 3 is out now! github.com/MarlinFirmware… We're in the home stretch to the official release. One more big sprint to address all your outstanding bug reports and then we'll put a ring on this thing! #RepRap #3DPrinting #OpenSource
Would you buy a printer bed made of asbestos? Asking for a friend.
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!
Building… building… building… Marlin 2.1.3 beta 3 binaries all night long! @MarlinFirmware #RepRap #3DPrinting #OpenSource
Instead of a big block of support material, you can add a custom bridging mesh of a few lines to complete the top of a helmet or mask. The webbing can be easily clipped off after #3dprinting
Welcome @BigTreeTech @3dprintmetal @ecw3d to the big #3DPrintopia 2025 show! Every week we have more and more sponsors signing up and soon we will be selling out of spaces. If you want to be a part of this years event, please reach out today!
Details… Details… Just ordered a set of Trinamic TMC2240 SPI units from Amazon for test and tuning. These advanced stepper drivers are especially well suited to our fancy new Fixed-Time Motion System and Input Shapers. Once 2240 is sorted out let's tag this thing 2.1.3 okay!?
C'mon @Tronxy3 you can do better! You have gained a little bit of benefit from the use of Marlin Firmware, have you not? All we ask is that you politely provide the source code to all customers who ask and at least not throw insults at them. #OpenSource #GPL #3DPrinting

Whatever vitamins you're taking, keep it up! The innovation and quality of your contributions to fix, improve, and extend the power and capabilities of all kinds of hobbyist making robots have been especially good in recent times! #RepRap #OpenSource #3DPrinting
“Don’t let the perfect be the enemy of the good.” If you're interested in motion theory, robotics, CNC … and looking to build your C / C++ coding skills this is the opportune moment to join us in moving the state of the art forward! #Coding #OpenSource #RepRap #3DPrinting
Back on the job getting the latest beta release out. twitch.tv/thinkyhead
If you invited us, well, we'd show up! With something to say… eloquently. #3DPrinting
