Smoothie making it's first steps ! The steps and dir pulses are outputed to LEDs here. Here it's playing a production gcode file and everything seems fine.
Smoothie is a project of porting Grbl ( http://dank.bengler.no/-/page/show/54... ) to ARM. It will also be object-oriented, and highly modular ( as in : you can add most functionality to it without having to touch any of the other code ). It will be GPL when it's released, but you can also get the pre-alpha code right now by emailing firstname.lastname@example.org.
Right now it's missing a configuration storage mechanism ( an sd-card ), and a laser output module so that I can test it with the laser cutter. Also the step timing is done using the Mbed library, and it would probably be better using the bare timer instead.
