Wowzers!

Hey RepRappers, Thinkyhead here with another Marlin Firmware project update!"Let's push this puppy out!"So wow, what can I say? When I jumped in to help push through the 1.1.0 release I guess I didn't know what I was getting into! The number of new patches added since 1.1.0-RC3 (way back in December) nu...

Mixing Extruder Support

Mixing Extruders are becoming far more common. Thanks to your support Marlin 1.2 will be ready for them. #RepRap #3DPrintingA few years ago, a student in the University of Bath's Mechanical Engineering Department named Pia Taubert, under the supervision of Dr. Bowyer et. al, wrote a dissertation on how to make a mi...

Fixing CoreXY and CoreXZ

Marlin supports a variety of 3D printer designs, including Cartesian, which moves X, Y, and Z directly, Delta, which moves the carriage indirectly, usually with three arms mounted on vertical carriages, and SCARA, which uses a dual-rotary-arm to move in XY. All of these designs are well-supported in Marlin 1.0.2, and w...

Marlin Firmware Update

I took a brief hiatus from programming Marlin during the holidays and spent lots of time testing out 1.1.0-RC2 and RC3 using my RepRap, a self-sourced Prusa i3 that I call "Millie." Everything worked well for me on the software side. I only wish I had more equipment to test on. I had an offer of a graphical dis...

Release Candidate 2, Better Documentation

Hey folks, here's a quick update for November.I've been slowly getting acquainted with my new city — Portland, Oregon — where I now have a pretty stable home-base with enough room and solitude to work and experiment. I've had less freelance work lately, so I've been working on calibrating my 3D prin...

Marlin 1.1.0-RC1 has been out for a little while now, ready for public testing and your feedback. There are many improvements that should make your printing experience with Marlin a lot smoother.A lot of changes have been made since 1.0.2, so there are probably some outstanding issues, but I expect them to be relativel...

Start your CoreXZs!

Marlin has had CoreXY support for a while now, but for some reason CoreXZ has been waiting in the wings for a proper implementation. After a couple of days hacking and debugging I'm happy to report that CoreXZ support has been added to Marlin's Development branch, and according to testers it's working great...

Bed Leveling for the masses

Automatic Bed Leveling allows a 3D printer equipped with a suitable probe to test the height of the print surface at multiple points and to use that information to compensate for its overall tilt. When set up properly, bed leveling guarantees a good first layer, and thus improves the whole print. The procedure itself i...

New Marlin Firmware features

https://www.youtube.com/watch?v=2niF8_XZ7xs Here's a video from December 2014 in which I talk about some of the more interesting Marlin features I was working on at that time, including the Hitachi LCD progress bar now included in Marlin 1.0.2.You can tell I was very excited the feature to sort SD card files on the...
