In case you missed it, I was a guest with Tom and Stefan on The Meltzone Podcast a few months ago, talking about the future of Marlin Firmware in a world of fast and inexpensive proprietary Bambu printers and decent alternatives like RepRapFirmware and Klipper. A great conversation and a lot of fun.
Marlin 2.2 is just around the corner, with a whole new motion system and a huge number of improvements. There’s still a vast space for single-board printers, a vast RepRap community, and g...

Hey everyone. Sorry for being so antisocial during this long world crisis. I've been facing challenges in health and well-being, driving myself a little too hard and not keeping up the best habits or sleep. In fact, right now I'm on this weird 3pm-6am waking schedule, but I have to admit that I prefer the peace and silence of the small hours to the sun's loud glare.

In case you missed it, I just set up a Marlin Firmware server on Discord — a good way to keep in touch and get extra support.
If you're pledging at the $5 level or above you'll get an instant invite link that assigns you to the "Patron" role. This role will give you some extra privileges on the server once I figure out what this popular communication tool can do!

Hey everybody! In case you missed it, during his whirlwind trip to Bay Area Maker Faire 2018, Tom Sanladerer took the opportunity to bop on over to Austin, Texas for a visit. While he was here he sampled the local Tex-Mex, gathered some footage for the RepRap documentary under development, and did an interview with me about Marlin Firmware.
In this wide-ranging interview we talked about some of the interesting technical aspects of Marlin, the challenges of open source development, and —with ...

I got two of these units recently and have been making some improvements in Marlin to support them better and add more capabilities. They're a great addition at a very low cost.

If you didn't know, February is Marlin Housecleaning Month! All my efforts (and yours too!) will go towards cleaning up old issues, fixing known bugs and hunting down bad behaviors. And, of course, this also means tweaking and improving the user experience, which is really just getting its start in the main Marlin fork.
As part of this whole crusade I'm collecting all Marlin's graphical elements into files for easier access and to pro...

Even though Marlin 2.0 is going full blast incorporating support for the latest, greatest, and fastest 32-bit boards and micro-controllers, I haven't forgotten about 8-bit AVR! I'm always looking for new ways to optimize Marlin so that it can run faster, smoother, and cooler on the majority of 3D printers.
Last year I took a stab at optimizing graphical display updates to prevent stuttering (caused by a "starved" planner). Within hours of posting that update, there was a sudden influx of help ...

Throughout Marlin's 5-year-long history, all its high level movement, G-code handlers, and main loop code has lived together in a single file. growing in size with each new release. With Marlin 1.1.5 (out now!), this file has ballooned to over 13,000 lines of code. Any code guru will tell you that's generally bad practice!

This video demonstrates the new marquee scrolling feature. I'm sure this style of scrolling is included in some versions of Marlin out there, but oh well, I just implemented it today for inclusion in Marlin 1.1.4 (coming soon) because it's the little things that I feel like working on right now.
Well, that… and the previous scrolling that I did for 1.1.3 just resets the message back to the start when it reaches the end of the available space. It's hard to follow and needed a-fixin'....

Marlin has a lot of moving parts that need constant oiling, and as 3D printers become more sophisticated, the demand for new and better features is ever-changing. We've a lot of improvements already underway, and Marlin 1.1 is shaping up to be a great update.
So as we go forward into 2017 we'd like to know what kinds of features and improvements you most want to see in your 3D printer firmware.

A Special Thank You
Until recently I only had one humble printer to work with: Millie, my trusty self-sourced Prusa i3. But a few months ago, when I was struggling with delta code I received the donation of an inexpensive "Micromake" deltabot from a very nice guy in Japan, who also threw in a portable oscilloscope and a pair of extra RAMPS boards for good measure. They have all turned out to be very useful in moving Marlin forward.
So, to you, Katsumi, I say "Dōmo ariga...

Configuration is a constant source of difficulty for Marlin users. After all, we just want to pick the right installation for our machines, download and install Marlin. And when it comes time to upgrade to the next version (as you certainly will soon!) it would be ideal to just use our existing configurations and build.
Of course, it's never that easy. At least, not at first.
For Marlin 1.1 one of my priorities was to maintain the existing configuration system, but improve settings w...

Graphical Displays
Last month I received a RepRap Discount Full Graphical Display donated all the way from Australia! Of course the very first thing I did was fix up the Marlin status screen. The XYZ coordinates needed to be able to show negative values, so that was the first fix. I centered the nozzle and hot-end temperatures on their graphics. And I got rid of visual noise like the empty "--:--" time value.<...
