There is work going on to modify AXIS 
http://www.linuxcnc.org/docs/devel/html/gui/axis.html  to better suit 
glue gun printers as well as SLA/DLP/SLS 3D printers. Axis was designed 
around cutting tools about 10 years ago and needs a few changes to 
better fit additive manufacturing.

EMC2 currently can easily control your type of 3-axis stage. It's just 
like a 3-axis mill only with a nozzle on an extruder instead of a 
cutting tool in a spindle.

The main problem with using the BBB as a printer controller is its poor 
GPU if you want a UI display on the printer.

We are working on drivers for use with the MESA FPGA cards 
http://www.mesanet.com/fpgacardinfo.html  that work with low cost (~$50) 
ARM SOC boards such as the cubieboard http://cubieboard.org/  that can 
support HD video for a user interface such as AXIS.
