bUltimaker is an online firmware builder for Ultimaker Original and Original+ 3D printers.

It offers a simple web interface to build an Ultimaker firmware from sources.

It is aimed at (advanced) end-users who want/need to build a custom firmware for their Ultimaker Original printer.
Build options are limited and constrained to ensure safe builds.

If you are an expert users/developer who want to set and try all possible options, this builder is probably not for you ;)

The builder evolves in parallel with the associated firmware branches:

• Marlin for Ultimaker Original / Original+ (Stable)
• Marlin for Ultimaker Original / Original+ (Experimental)

It will not work with other Marlin forks.

The features supported by the builder are listed in the README file of the associated firmware repository.
