I just completed the first test of running EMC2/LinuxCNC on Ubuntu with the HobbyCNC board. I connected a motor to the X-axis and started EMC2 with the “Axis” interface. I then told it to execute the default G-code file it loads with. Lo and behold the motor started spinning! I then moved the motor to the Y and Z axis and repeated. Seems to work well.

I didn’t notice any stalling so the problems I experienced with Windows XP and Mach3 must be due to Windows XP…

Here is a video:

Details on how to install EMC2 from source along with RTAI will follow when I have them ready. Also I will post the configuration files for the HobbyCNC board a bit further on in the project when I have more confidence that they are correct.
