Getting the Firmware

We recommend using the fantastic Marlin firmware with our Mark2 printer kits. A version of Marlin pre-customised for the Mark2 printer is available on GitHub, and we will endeavour to keep it up-to-date with the latest Marlin releases.

Generally, the easiest way to get your printer up and running is to download the pre-customised firmware, and to upload that firmware to your board following the guide here.

However, if you want to use a different firmware version (i.e. a newer development version of Marlin), or just if you want to check the changes for your own reference, the page here details the main changes that need to be made to suit the Mark2 3D printer.
