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.
If you like using Mainsail as your print host you will be able to do that with Marlin a lot more easily on the next update. The key is a little connector called Serial2Moon.

Robots are 3D printing full-size ship hulls.
ㅤ
CEAD’s Faber Navalis system uses robotic arms to print complete marine hulls up to 12 m long and 4 m wide in a single automated run—no molds, no segmentation, and no heavy manual assembly.
ㅤ
A 12-meter RIB-style prototype for the Royal Dutch Navy was printed in 8 days, tested during NATO’s BOMA exercise, and sailed for four days with the Navy in Den Helder. Traditional delivery timelines for similar vessels often run into years.
ㅤ
The hulls use glass-fiber-reinforced HDPro, roughly 10% lighter than comparable fiberglass while offering higher impact resistance than standard HDPE, plus UV stability and recyclability. Primary targets are USVs, RIBs, workboats, and patrol craft.

I think people underestimate what soaking in a subject matter for years does to your ability to solve problems in it.
I started HueForge without an inkling of color theory or of the variety of color models out there. I had NO idea how hard it would be to get a computer to tell two colors apart.
Now - with the help of coding tools and over 3 years of work in the space - I can solve problems in hours that I just didn't have a framework to solve in the past at all. It was the earned expertise that suddenly makes old, intractable problems, well, easy to formulate and solve.
None of my coding agents have ever suggested these solutions, the quality of the request for complex tasks is super important, but without them, I would not be able to experiment and develop novel solutions (well novel to me) to problems that my user's have had for years. It's a crazy new world in software, but experience still matters a WHOLE lot.

This 3D Printer is INSANE
@Printcepts showing off a 3D Printer that is a belt printer, a corexy, and a toolchanger, all in one, all at the same time!!

5 Axis 3D Printing!!
Take a look at this 5-axis 3D printer that was designed and built by college students that we spotted at @3DPrintopia!

So cool to see our merch out in the wild and being put to good use! It’s a classic collection for a limited time. But follow and stay tuned for upcoming new 2027 designs! marlin-firmware-schwag.creat…
I made some small chocolate ice cream sodas for my parents and I. It is basically just soda water and icecream. I made the soda water with my @SodaStreamUSA. Since I used chocolate ice cream I didn't need the chocolate syrup.
I am eating mine in my @MarlinFirmware mug.😋
We get a lot more submissions of code by #agents lately, and also a marked improvement in quality and comprehension.
But to code Marlin properly they need more!
Tell yours to use the Simulator with http agent interface (and new visualizations).

Thanks to @AnthropicAI for hooking us up with a generous allowance of Claude Max 20x and to @github for Copilot!
In our interactive sessions with Opus 5 and GPT 5.6 Luna we’re doing incredible things, building tools, closing issues, making improvements in record time.

The dream team at Virginia Tech thought: why not?
They built an automated plate changer for Voron printers that actually picks up finished plates, store the prints, and place a fresh plate back on for the next print. That's pretty cool! 🔄🖨️
With their WorkCell system, the whole workflow runs with minimal supervision, from one print to the next.
And what a treat it was to see our BIQU CryoGrip Pro Buildplate featured in this genius setup. 👀
This is where DIY gets interesting—when "what if?" turns into "why not?"

I'm recovering the original code and assets of a little #Amiga game I wrote for Capstone in 1989, "Bill & Ted's Excellent Adventure."
It should be fun to remaster!
I spent an intensive 40 hours with #Hermes and Ghidra to get most of the way there!

Anyone still prefer a written review vs video?
If so I've converted my LDO Voron V0.2-S1 Kit Review into a written blog-like format with LOTS of pictures and insights. Including some details left out of the video for time considerations
