Is it possible to use the librarys for the lcd screen on a different printer board? would it require much work other then wiring and adapting the code abit?
What do you mean exactly by another board? Another printer mainboard with the same LCD panel? It depends if your mainboard has a serial (uart) connection available and on you C++ programming skills. It is far from trivial.
hmmm i may just end up hooking up a raspberry pi and octoprint
