We'll eventually need something that can detect both the 3.8 and 4.x
locations for this file.  Feel free to add that if you have time.

Now you're squarely in the middle of the velocity extrusion logic and
python generated HAL configurations, which I'm not particularly
familiar with.  AFAIK there's nothing kernel specific about the
velocity extrusion logic, but it's obviously not working.

I'd recommend trying a more traditional configuration that isn't doing
velocity extrusion.  I'm most familiar with the CRAMPS.ini config:

https://github.com/machinekit/machinekit/tree/master/configs/ARM/BeagleBone/CRAMPS

...since it started as the config file for my first printer, but you
could try any of the BeagleBone configs that use the universal overlay
(which I think is most of them except for the BeBoPr configs).
