I'd say LinuxCNC is ready, but there are still issues with the platform in general: * There is currently no available I/O cape for the BeagleBone that is targeted at industrial control. Depending on how willing you are to wire up something from scratch, and how complicated you need your I/O protection, this could be a minor issue or a show stopper. Your mill also needs to be using step/dir control. * It depends on what you want to do for a display. The HDMI output on the 'Black has been causing nothing but problems for most folks, and will never run high resolutions like 1080p. If you are OK with oneof the 4" or 7" LCD capes, or are willing to by a specific HDMI monitor know to work with the 'Bone that should get you a display, but LinuxCNC has not been tested with a native display AFAIK. * Even if you do have a working display, you need to choose your interface wisely. I haven't been able to test with a native display, but the 'Bone has no 3D acceleration so I suspect Axis will always be a CPU hog and you'll need to use one of the lighter-weight interfaces. * Finally, you would very definitely be an early adopter. If you're OK with that, I'd say it's ready to try. If you want something you install and it runs without issue for the next few years, the 'Bone isn't there yet. - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlG+7uAACgkQLywbqEHdNFz/XgCeKU8vVh7sTU5mKL4NLeGWHKZ6 4FUAoPB+5BMaWROTd3kLhkCymZv2tKuU =f7rX -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
