BeagleBones At MRRF

[Jason Kridner] – the BeagleBone guy – headed out to the Midwest RepRap Festival this weekend.┬áThere are a lot of single board computers out there, but the BeagleBoard and Bone are perfectly suited for controlling printers, and motion control systems thanks to the real-time PRUs on board. It’s not the board for you if you want to play retro video games or build a media center; it’s the board for building stuff.

Of interest at the BeagleBooth were a few capes specifically designed for CNC and 3D printing work. There was the CRAMPS, a clone of the very popular RAMPS 3D printer electronics board made for the Beagle. If you’re trying to control an old mill that is only controllable through a parallel port, here’s the board for you. There are 3D printer boards with absurd layouts┬áthat work well as both printer controller boards and the reason why you should never come up with the name of something before you build it.

[Jason]’s trip out to MRRF wasn’t only about extolling the virtues of PRUs; Machinekit, a great motion control software, was also there, running on a few Beagles. The printer at the BeagleBooth was running Machinekit and apart from a few lines of GCode that sent the head crashing into the part, everything was working great.
