The Arduino is all fine and popular, but compared to what is already available stock for the Beaglebone any such solution - which will be a lot of work too - will be a complete dog in terms of stepper speed and phase noise the Beaglebone port of LinuxCNC can use the builtin coprocessor of the TI3335 chipset and bang stepper lines at 200kHz if you can find a powerstage and motor to sustain that again: this is _stock_, done, ready to go, not blue skye - build from here: http://git.mah.priv.at/gitweb?p=emc2-dev.git;a=shortlog;h=refs/heads/arm335x-hal-pru-module no reason to reinvent the wheel in square form ;) - Michael > At 4.33 inch x 3.35 inch (11 cm x 8.5 cm) this would make a very compact > control system for CNC.
