They offer standalone and installable versions. For me this was a Jessie image from the eLinux Beaglebone builds page. To get the Beaglebone Black (or Green or whatever other computer youвЂ™re using) ready you should at least get an up-to-date copy of whatever OS you want to run. One resource intensive process is the rendering of the timelapse with FFMPEG, for which I think I have a work around for by compiling some libraries (libjpeg and libgphoto2, libavtools etc.) and not using the precompiled ARM binary. When I am running prints serving over the LAN or tunnelled in with VPN or SSH it uses around 3% CPU to control the print and maintain the server connection including the webcam.

The Beaglebones are also lacking a bit in graphics capability compared to the Pi, but for a headless server that is not a factor. Whatever the specs and cost, Beaglebone Blacks (and Greens) are a great RasPi alternative and have a little more capability as a Linux server. The Beaglebones go for a little more $$ now and still have 512 MB of RAM but increased to 4gb of eMMC with basically the same 1 GHz TI ARM cortex A7 processor (I think, donвЂ™t quote me). I boot and run it off the SD card slot anyway which I will get to. The A6 is a little crippled compared the newer C and Green revisions of the board, but half a gig of RAM and 2 gigs of eMMC still works for me.

This thing cost me $ 55 in May 2013(14?) and still has the balls to run a full Debian system with some daemons on like 1 Amp including accessories. I jumped on the Beaglebone bandwagon early-on I donвЂ™t care that the Raspberry Pi has a larger following. I wish there was functionality within Octoprint to automagically try to reconnect to the printer and kill the hotend and bed after a catastrophic communication issue but am not sure this exists yet. The worst part about this is that the printer hangs after the last move / command received and does not cool down which can be a dangerous situation.

If you suffer random serial dissconnects mid-print itвЂ™s likely a cable issue.

It sould be an issue with my cheap 4-port USB hub, but IвЂ™m not sure. I have had issues with USB connectivity though, and have tried different cables, long and short, and have had the best luck with one that has extra shielding. Octoprint picks it up no problem over USB/TTY with a reasonably modern kernel. The Duplicator i3 runs a Melzi board with a Repetier based firmware.
