Yup Mactec54 I see you still have bad feelings about UCCNC because you have never described and likely connot describe what is better in those controls, it is just your little feelings again.
Arm Cortex A8 is not a motion control CPU, it is a general Arm microcontroller. The beagleboard populates that microcontroller. So you are again wrong.
Acorn did not even put in the effort to design their own motion controller, they just used a beagleboard.
At least all those other controllers having their own motion controller board designs.
