[Jason Kridner] – the BeagleBone guy – headed out to the Midwest RepRap Festival this weekend. There 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 that work well as both printer controller boards and the…

Machinekit on BeagleBone with delta 3D printer — I need to do my own version, because this is getting easier all the time
Design | Make | Share
tl;dr: Instructions to run (and calibrate!) a linear delta 3D printer on MachineKit. I use a CRAMPS board but much of this applies to other boards too.
The first post in this series showed how to get a CRAMPS board up and running with MachineKit, along with how to verify that each board feature works as expected.
This second post shows how to get a Linear Delta 3D printer (a la Rostock, Kossel, 3DR, Wolfstock, etc.) running and calibrated with this same CRAMPS/MachineKit combination. Most of the instructions will apply equally to other boards like the BeBoPr.

The Hackaday folks and I were both checking out cool stuff at Chicago’s Pumping Station: One
The Hackaday Prize was about to launch but the date wasn’t public yet. I decided to do a pre-launch tour to visit a few places and to drop in on some of the Hackaday Prize Judges. It started in Chicagoland, looped through San Francisco for a hardware meetup and Hardware Con, then finished with visits to [Ben Krasnow’s] workshop, [Elecia White’s] studio, and the Evil Mad Scientist Laboratories.
The Prize is now running and it’s time for you to enter. Look at some of the awesome hacking going on at the places I visited and then submit your own idea to get your entry started. Join me after the break for all the details of the adventure.
