Recent stable builds of the firmware can be found here : https://github.com/Smoothieware/Smoothieware/tree/edge/FirmwareBin

Very latest are called …_latest.bin

You can also find automated builds here.

Then you can flash the new binary by following the guidelines here http://smoothieware.org/flashing-smoothie-firmware

If you want the very latest bleeding edge, you can also compile it yourself, come to IRC if you need help with compilation.

Smoothie can be found on GitHub at the following address: 

• https://github.com/Smoothieware/Smoothieware

You can retrieve the code using git :

git clone git://github.com/Smoothieware/Smoothie.git

For instruction to compile Smoothie from source, please see compiling-smoothie.

You will be on the edge branch by default.

The edge branch is always more up to date.

You probably want to be on the edge branch to compile.

If you want to compile the master branch, please do :

git checkout master

Unless you can say «I fully understand why I need the master branch», it's pretty certain you don't. Please use edge.

The edge branch is automatically built for every new commit to the repository.

You can find these automatic builds below with different possible configurations, in particular the default build (for 3D printers), and the CNC build for different amounts of axes:
