About the Machine

The C-Beam machine is based upon the OpenBuilds CBeam machine which is documented here http://openbuildspartstore.com/openbuilds-c-beam-machine/.  It uses a smoothieboard as the controller the documentation for the smoothieboard is located here http://smoothieware.org/smoothieboard-v1.  

To connect and control the machine you will have to download printrun from http://www.pronterface.com/#download. Once this is downloaded and installed you can connect to the CNC by plugging in the USB cable and using the following parameters.  Port (Will depend upon machine) baud speed = 115200.
