I'm trying to find a way to connect my "Full Graphic Smart Controller Graphical LCD (128x64) Screen" to my Printrbot 1405, so I can control it via the rotary encoder, and use the SD Card of the Smart Controller, rather than the built in SD Card Reader.
I'm familiar with Firmware alteration, uploading it, etc, however I think someone has already covered this at some point, and I'm wondering if anyone can point me in the correct direction since my search has come up dry.
My main concerns of starting to alter the marlin firmware, is that uploading to the Printrbot might kill it if the pin outs are wrong....?
I'm hoping that someone can give me a head start or pointers.
Thanks
