-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 So I finally got enough of the pieces put together to run a print on my MendelMax 3D printer using the BeagleBone with the BeBoPr cape and LinuxCNC. This is using the 3.2 Xenomai kernel from Michael Haberler to get LinuxCNC working well on the 'Bone, and custom PRU code doing step/dir and pwm generation. Thanks also to Ian for the bb_gpio module, which came in very handy.
Video or it didn't happen... My first ever 3D print from the BeagleBone, second print using LinuxCNC (the first LinuxCNC print used an x86 running preempt-rt). The X axis is mirrored and the configuration and slicing settings need to be tweaked to improve print quality, but overall it came out pretty good: http://www.youtube.com/watch?v=n2IoHOZipLU ...I particularly like the acceleration control in LinuxCNC. It seems smoother than the Arduino code. Now if I could just get a slicing program that outputs true arcs and nurbs... :) Code is in the arm335x-hal-pru-tasks branch of Michael's git repository: http://git.mah.priv.at/gitweb?p=emc2-dev.git;a=shortlog;h=refs/heads/arm335x-hal-pru-tasks Up next is the great migration to a 3.8 kernel, where I get to craft the magic device tree fragments necessary to get this all working again. - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlGqI7sACgkQLywbqEHdNFwEkwCgw6n50qq9fP9lQLltBwTTp/0u rm8AoMU5hhohJljA6gpu5T+wsE/sOAES =6IRC -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with <2% overhead.
