Did you know ? Smoothieware has a very very active IRC channel on Freenode : http://smoothieware.org/irc
In the IRC channel, you can ask for help, discuss firmware development and talk about your favorite robots.
Often peaking at 100 persons connected, it’s ( as far as I know ) the most active channel of any 3D printing or CNC milling firmware, and it’s a great place to stay connected to, to follow news on firmware dev, or help newcomers.
