BeagleBones At MRRF

Hackaday

[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 Delta configuration + calibration

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.

Crazy Whirlwind Pre-Hackaday Prize Launch Tour

The Hackaday folks and I were both checking out cool stuff at Chicago’s Pumping Station: One

Hackaday

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.
