The Beagle is in a different class from the Raspberry Pi and Arduino modules. The dual PRU's allow it to do things that outshine the LinuxCNC systems from 20 years ago running on Pentium 33 size machines. The nice thing about them is they are small. A small 1GHz 32 bit PC in the tiny brick format costs into the hundreds of dollars. But that's also why I asked. Comparisons that I've done with a Pi3 and a BeagleBone Black show for normal graphics GUI and even compiling programs with Lazaras (Delphi Pascal) that the Beagle is about half the speed but then the Pi3 has a dual processor core. Probably still not fast enough to do the real time stuff for Linux. But it does be the question doesn't it? If Linux could run real time on much slower PCs 10 years ago, why can't it run on the much faster with more memory Beagles? Has LinuxCNC really changed that much? As I mentioned in the reply to Andy. I'm hoping to start a conversation with people who have used both and perhaps even Mach3.
