While my beast has routing as its first planned jobs, I also plan to print 6' wings and fuselages for R/C aircraft, so I definitely need to keep the extruder heaters and sensors front and center.
What packages am I likely to need for routing on the BBB? for printing? Can LinuxCNC do routing and printing? Both boards mention something about some software/firmware that comes on/with them... what is that about?
