PlatformIO and Marlin – and how to have separate config files, for different 3Dprinter while sharing the same code.

I am using Marlin 2.0 to control my 3D printers, Marlin 2.0 can still be compiled and installed from the Arduino-IDE,although I use the supplied Makefile. To take advantage of other processors you have to use PlatformIO. In this article … Continue reading

Marlin 2.0 using Makefile (and reclaiming io-pins on atmega1284p based mainboard)

I am using Marlin 2.0 to control my 3D printers, I like to be in full control so I compile my own firmware, adding my own tweaks. Most people probably use the Arduino IDE to compile and install the firmware … Continue reading
