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 ...

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.

I just got back from 3D Meetup Sweden where I was invited to give two 45 minute presentations covering a bit of the history of the maker scene and (of course) the future of Marlin Firmware. (The presentations will be posted online soon.) The event was amazing and transformative, and I look forward to attending again if they will have me!
Most exciting for me, also in atte...

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.

And, of course, this also means tweaking and improving the user experience, which is really just getting its start in the main Marlin fork.

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 (cau...

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 t...

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 ...

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.
