The PRU can do a great job with step/dir generation. Anything that has encoders should really be running with FPGA hardware and something like the Mesa boards. I was just trying to point out that ARM parts and boards are available that more directly compete with the "traditional" Atom motherboards currently popular here (including conventional PCI/PCIe expansion slots!). IMHO, the 'Bone makes a good low-end solution for things like 3D printers, while ARM + Mesa boards can compete against the Atom motherboards in the more traditional LinuxCNC space. And while there's not as much need to migrate away from x86 at the upper end, factors such as power consumption and cooling could make the ARM parts attractive vs. x86. > I'm building Rostock-like device which I intend to use for both > small milling/engraving and 3D printing.
