Thanks Will...thanks for your comment. I should have made it clearer, I am really looking I think for a hardware tie-in rather than software solution to use microprocessors like the Azteeg X5, BBB, pcDuino with the CNC 5 axis stepper board. Smoothieware or LinuxCNC are control software that I want to use for my scara printer adaptation, I'm just looking to see if anyone will comment on how possibly to use the Azteeg X5, BBB, or pcDuino3 with the 5 axis CNC board from stepperonline.com. Thanks again.
