So i've run into a bit of a problem. I'm trying to install LED Strips on each of my printers as status indicators, but the boards I am using (Rambo Mini's on the Prusa I3 Mk2MM machines) Don't have very many extra pins & it looks like implementing them into the printers themselves will be quite the headache.
My solution would be to see about using my Raspberry Pi 3's, which are running Repetier Server to run the printers, to control the lights accordingly.
Is there any native controls or pins set up on the Raspberry Pi firmware that already supports this? I haven't managed to find any decent documentation on it as of yet.
Thanks in advance!
