The LinuxCNC wiki has a list of common issues that affect RT performance:

It reads:
Configure and build for Xenomai:
cd src
./configure --with-threads=xenomai-user --enable-run-in-place
make
sudo make setuid

BUT I think it should read:
Configure and build for Xenomai:
cd src
sh autogen.sh
./configure --with-threads=xenomai-user --enable-run-in-place
make
sudo make setuid

You should try running linuxcnc in sim-mode. Does that work? That would indicate a problem with the parport driver.

In general it's best to post all your configuration files and your error output on either the linuxcnc form or the linuxcnc mailinglist. My experience is that there is usually someone there who knows how to solve your problem and can help you.

This is the sauce I was looking for. I have a MAXNC-10cl that I was finally able to get moving because of this sample code. I still have a lot of tuning to undertake before it's ready. Thanks!
