Replicape BBB-flasher ready for download

Yes! The Thing/Replicape BBB-flasher image is now finally ready for alfa testing! This flasher image has everything you need for using the Replicape for controlling a 3D-printer or other CNC-machine. It's a minimal Angstrom SystemD image with Redeem, Toggle, CuraEngine and Octoprint pre-installed. There is no X or Wayland due to the missing SGX drivers

One stepper driver, two stepper motors

  Wiring two stepper motors on one stepper driver I've had a couple of questions about whether its possible to drive two stepper motors with one driver, for instance to control a printer such as Prusa I3 or similar which uses two stepper motors on the Z-axis. The answer to that is yes. Just make

Reach expansion board for Replicape ready for review

I have gotten a few requests for an expansion board to accompany the Replicape lately, so I have made an inital version for anyone interested in adding more extruders than the standard two present on Replicape. The Reach board uses the spare PWM and ADC pins from Replicape to keep the cost down and the

Replicape printing a tree frog

Hey, I took a video of the Replicape finishing a print last night: The video shows the Thing printer, which is a demo-printer for displaying the capabilities of the Replicape and the Manga Screen and also for developing Spline, which is a all-metal remotely cooled dual Bowden extruder that I'm working on. Here is a

Writing Clutter apps on BeagleBone Black using Python

Clutter is a great SDK for writing hardware accelerated GUI apps for embedded devices. It can run on X and Wayland, but it can also use the framebuffer directly and bypass the overhead of a display manager completely, ideal for embedded devices. I have spent the last few weeks working on getting Clutter to run

3D rendering by PVR SGX on BeagleBone

Texas Instruments recently (Nov 18 2013) released the alpha version of the SDK 5 for the SGX530 3D engine that is built in to the BeagleBone (black). The 3D engine interface is special since it is one of the few parts (only part?) that is closed source and so the community is dependent on TI
