Whatever it is called – it's an incredible bit of software.
It took me a bit of time to get my head around all the bits and pieces; now that I understand what is going on, one realizes just how flexible it is. I'm glad I went LinuxCNC over some of the other solutions, and the price is right!
(have CNC 4-axis mill, joypad input device, and now a CNC4PC MPG Pendant – looking at CNCing one of my lathes next)
