BBB for CNC

Hello everyone, I’m trying to build a CNC machine using Beaglobone black. I created a Debian Machinekit Image, but I had this problem when starting LinuxCNC, someone can help me?

Stepconf only runs on x86 systems with a parallel port. On the BBB,
you have to manually craft your machine configuration files, but there
are several example configurations you can use to start from.

Also, it's probably better to ask machinekit specific questions on the
machinekit Google group vs. the BeagleBoard group, but there's a lot
of overlap.
