Do this:
1. Remove all linuxcnc* and emc2* packages.
2. Add these two APT source lines to your repository list:

Well, going through the procedure to get it from the buildbot and install again
worked. It didn't update anything (because it didn't need to). Perhaps the

Performance depends on if you are doing everything is userland or in the
kernel. For a good overview of BeagleBone performance with driving servos:
http://veter-project.blogspot.com/2011/09/real-time-enough-about-pwms-and-shaky.html
They eventually settled on using Xenomai with a kernel driver

The BeagleBone uses 3.3V on the expansion headers, so for building a breakout
setup you would probably want to include some level conversion kits to convert
that to 5V (and for isolation). Adafruit has a nice selection of addons for
the BeagleBone:

How can I run this, Chris? I pulled the latest off the buildbot and changed
our config according to your instructions on the wiki but gscreen doesn't seem
to be in there anywhere (I can't find the executable).

GPIO driven by bit-banging from the ARM processor is approximately 240
ns, and it apparently
holds the CPU in a wait state until the operation is performed by the
GPIO multiplexer.

The GPIO pins can be written by the 700+ MHz ARM CPU, but they
