Printing on the Beaglebone
==========================
Unfortunately, the Beaglebone processor can sometimes struggle to run
OctoPrint well. Print stalls have been known to occur on complex
prints (the printer may move faster than OctoPrint can send movement
commands). If this occurs, consider using the "virtual_sdcard" feature
(see [config/example-extras.cfg](../config/example-extras.cfg) for
details) to print directly from Klipper.
